Description

Stepped lifting mechanism for conduit

Technical Field

The utility model relates to the technical field of cylindrical part conveying, in particular to a stepped lifting mechanism for a guide pipe.

Background

The valve guide pipe is a guide device of the automobile engine valve, and ensures that the valve does reciprocating linear motion, so that the valve and the valve seat ring can be correctly attached.

The raw material of the valve guide pipe is cylindrical, and batch automatic feeding is difficult to realize by adopting modes such as a sucking disc, a clamp and the like; at present, the loading of the valve guide pipe during automatic production is realized in a manual mode, the efficiency is low, and the labor cost is high.

SUMMERY OF THE UTILITY MODEL

In order to solve the above technical problems, the present invention provides a step-like lifting mechanism for a catheter.

In order to solve the technical problems, the utility model adopts the following technical scheme:

Furthermore, a sliding gap exists between the lifting plate and the fixing plate; when the top surface of the lifting plate moves upwards to be parallel to the top surface of the fixed plate, the guide pipe rolls to the top surface of the fixed plate under the component force of the self gravity; if only a sliding gap exists between the pair of lifting plates and the fixing plate, the guide pipe can roll from the top surface of the lifting plate to the top surface of the fixing plate when the top surfaces of the lifting plate and the fixing plate are parallel because the lifting plate and the fixing plate are obliquely arranged.

Further, the clearance between the lifting plate and the fixing plate is smaller than the diameter of the guide pipe; when the top surface of the lifting plate moves upwards to be higher than the top surface of the fixed plate, the guide pipe rolls to the top surface of the fixed plate under the component force of the self gravity; if there is too big clearance between a pair of lifter plate and the fixed plate, even both incline settings, the pipe still probably blocks between clearance between them, needs the lifter plate top surface to be higher than the fixed plate top surface, just can ensure that the pipe rolls to the fixed plate top surface from the lifter plate top surface.

Further, the lifting plate is arranged on the left side, and the fixing plate is arranged on the right side; along the direction from left to right, lifter plate and fixed plate slope upwards.

Further, the device comprises a base, a linear guide rail fixedly arranged on the base and a rack fixedly connected with a linear guide rail moving pair; the lifting cylinder, the conveying line and the fixing plate are all fixedly arranged on the rack; the whole lifting mechanism can slide along the linear guide rail, and is convenient to adjust.

Furthermore, the support plates are provided with N pairs in total and are sequentially arranged from left to right, and the lifting plate in each pair of support plates is fixedly connected with the moving end of the lifting cylinder; and starting from the second pair of support plates, when the lifting plate in each pair of support plates moves downwards, the top surface of the lifting plate can be parallel to or lower than the top surface of the fixed plate in the upper pair of support plates, and when the lifting plate moves upwards, the lifting plate can be parallel to or higher than the top surface of the fixed plate in the same pair of support plates.

Compared with the prior art, the utility model has the beneficial technical effects that:

the outer part of the conduit is cylindrical, so that the suction and the feeding can not be carried out in negative pressure modes such as a sucking disc and the like; the utility model adopts the step-shaped lifting mechanism, and the guide pipe is lifted up by stages through the repeated lifting of the inclined support plate and the lifting plate, thereby completing the batch and automatic lifting and feeding of the guide pipe.

Detailed Description

A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

Example one

A ladder-shaped lifting mechanism for a conduit 1 comprises a conveying line 10, a pair of support plates 20, a lifting cylinder 30, a frame 40, a linear guide rail 50 and a base 60; the support plate includes a lifting plate 201 and a fixing plate 202.

In this embodiment, the conveying line 10 is a conveying line composed of rollers and sprockets, and the conduits 1 are placed on the conveying line 10 in batches.

The inclined direction of the lifting plate 201 is from left to right, i.e. from left to right to up; the fixing plate 202 is parallel to the lifting plate 201.

A large gap may exist between the lifting plate 201 and the fixing plate 202, or only a sliding gap may exist.

When a gap exists between the lifting plate 201 and the fixing plate 202, the gap should be smaller than the diameter of the guide tube 1 to prevent the guide tube 1 from falling into the gap, and when the lifting plate 201 carries the guide tube 1 and rises upwards, the top surface of the lifting plate 201 should be higher than the top surface of the fixing plate 202; because there is a gap between the lifting plate 201 and the fixing plate 202, the guide tube 1 may be stuck in the gap when rolling along the top surface of the inclined lifting plate 201 toward the top surface of the fixing plate 202, and this phenomenon can be avoided when the top surface of the lifting plate 201 is higher than the top surface of the fixing plate 202, and the height difference between the top surface of the lifting plate 201 and the top surface of the fixing plate 202 is the standard for enabling the guide tube to roll smoothly onto the top surface of the fixing plate 202.

When only a sliding gap exists between the lifting plate 201 and the fixing plate 202, the lifting plate can slide relative to the fixing plate but the gap between the lifting plate and the fixing plate is small; when the top surface of the lifting plate 201 is flush with the fixing plate 202, because the lifting plate 201 and the fixing plate 202 are both inclined, the guide tube 1 on the top surface of the lifting plate 201 can roll to the top surface of the fixing plate 202 under the action of gravity, and one-time lifting of the guide tube 1 is completed.

The conveying line 10, the lifting cylinder 30 and the fixing plate are all mounted on the rack 40, and the rack 40 is connected with the base 60 through the linear guide 50, so that the position of the rack 40 relative to the base 60 can be adjusted conveniently and rapidly.

The moving end of the lifting cylinder is the cylinder piston rod.

Example two

The only difference from the first embodiment is that the second embodiment has a plurality of pairs of support plates, namely more than two pairs of support plates; many sets gradually and uprise in proper order to the extension board from left to right, and the difference in height can satisfy: and starting from the second pair of support plates, when the lifting plate in each pair of support plates moves downwards, the top surface of the lifting plate can be parallel to or lower than the top surface of the fixed plate in the upper pair of support plates, and when the lifting plate moves upwards, the lifting plate can be parallel to or higher than the top surface of the fixed plate in the same pair of support plates.

Taking two pairs of support plates with sliding gaps as an example, after the lifting plate 211 in the first pair of support plates moves downwards, the top surface of the lifting plate is used for bearing the guide pipe 1 transmitted by the fixing plates of the upper pair of support plates or the guide pipe 1 transmitted by the conveying line 10, after the lifting plate 221 in the second pair of support plates moves downwards, the top surface of the lifting plate is used for bearing the guide pipe 1 on the top surface of the fixing plate 212 of the first pair of support plates, and the top surfaces of the lifting plates of the first pair of support plates and the second pair of support plates are both provided with at least one guide pipe 1; at the moment, the lifting plates of the first pair of support plates and the second pair of support plates both ascend to enable the top surfaces of the lifting plates to be parallel to the top surfaces of the paired fixing plates, so that the guide pipes 1 roll to the top surfaces of the fixing plates from the top surfaces of the lifting plates, and at the moment, the top surfaces of the fixing plates of the first pair of support plates and the second pair of support plates are provided with at least one guide pipe 1. Because fixed plate and lifter plate all have certain width, and the width is greater than the length of a pipe 1 far away, so not only can upwards carry a pipe 1 at every turn, can also carry out batch transport.

The number of the support plates is set according to the height to be lifted by the catheter 1, and five pairs of support plates are arranged in the total in fig. 1, namely a first pair of support plates 21, a second pair of support plates 22, a third pair of support plates 23, a fourth pair of support plates 24 and a fifth pair of support plates 25.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
