Description

Screw-driven distance adjustment device

technical field

The utility model relates to a distance adjustment device, in particular to a distance adjustment device used for adjusting the width of a feed opening and having a self-locking function.

Background technique

With the development of my country's construction industry, building materials such as wood and gypsum board need to be processed into regular shapes in large quantities on electric planers or sawing machines. When building materials are processed, it is necessary to determine the reference side, and then adjust the width of the feed port according to the size of the processed material. Appropriate feed opening width can make the material not deviate during processing, and the processing accuracy can be improved. Most of the feed inlets of planers or sawing machines do not have width adjustment devices, and some feed inlets of workbenches have width adjustment devices, but these devices generally have problems such as unreasonable design, complicated structure, and inconvenient adjustment operation.

The above-mentioned screw-driven distance adjustment device is characterized in that the pressing plate is fixedly connected to the installation base by at least two bolts.

The above-mentioned screw-driven distance adjustment device is characterized in that the installation base is welded or fixed on the frame by screws.

The above-mentioned screw-driven distance adjustment device is characterized in that the driving handwheel is welded or fixedly mounted on the end of the threaded rod by screwing.

The above-mentioned screw-driven distance adjustment device is characterized in that: the connecting seat is welded on the movable arm.

Compared with the prior art, the utility model has the following advantages:

(1) The design of the screw-driven distance adjustment device is very reasonable, the structure is simple and compact, the operator only needs to rotate the driving hand wheel to complete the distance adjustment, and the device also has a self-locking function, which is very easy to use.

(2) The screw-driven distance adjustment device is small in size, light in weight, easy to disassemble and easy to maintain and carry.

(3) The screw-driven distance adjustment device has no rigid impact during use, has a long service life, and has a very wide range of applications.

(4) The production process of the screw-driven distance adjustment device is simple, the processing accuracy is not high, and many parts are very easy to produce and purchase, so its production cost is very low, and it is easy to popularize and use.

Below by accompanying drawing and embodiment, the utility model is described in further detail.

Detailed ways

A kind of screw drive type distance adjustment device as shown in Figure 1, comprises the installation base 2 that is fixedly installed on the upper side of frame 1 and plays a supporting role, also includes the threaded rod 8 that is used to drive movable arm 3 to move back and forth, and described The threaded rod 8 cooperates to form the threaded sleeve 5 of the threaded transmission pair and the driving hand wheel 9 for driving the threaded rod 8; the upper side of the frame 1 is fixedly installed with the mounting base 2, and the mounting base 2 The threaded sleeve 5 is fixedly installed on the upper side through the pressure plate 6, and the threaded rod 8 is arranged in the threaded sleeve 5, and one end of the threaded rod 8 is rotatably connected with one end of the connecting seat 4, and the connecting seat The other end of 4 is fixedly mounted on the movable arm 3, the other end of the threaded rod 8 is fixedly mounted with the driving hand wheel 9, and the outer edge of the driving hand wheel 9 is fixedly mounted with a ring for driving the driving hand wheel. Wheel 9 rotates drive handle 10 .

In this embodiment, the pressing plate 6 is fixedly connected to the installation base 2 through at least two fastening bolts 7 .

In this embodiment, the installation base 2 is fixed and installed on the frame 1 by welding or screws.

In this embodiment, the driving hand wheel 9 is welded or fixedly installed on the end of the threaded rod 8 by screwing.

In this embodiment, the connecting seat 4 is welded on the movable arm 3 .

The working process of the screw-driven distance adjusting device of the utility model is: firstly, the screw-driven distance adjusting device is fixedly installed at the working position, the operator rotates the driving hand wheel 9 clockwise through the driving handle 10, and the driving hand wheel 9 drives the threaded rod 8 rotates clockwise in the threaded sleeve 5, and the threaded rod 8 drives the movable arm 3 installed at its front end to move forward, so that the width of the feed opening becomes smaller. On the contrary, turning the driving handwheel 9 counterclockwise can make the movable arm 3 move backward, thereby making the feeding opening width larger.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any simple modifications, changes and equivalent structural transformations made to the above embodiments according to the technical essence of the present utility model still belong to Within the scope of protection of the technical solution of the utility model.
