Abstract

A casing of an oscillating maneuvering tool is provided with a motor and a switch used for controlling the motor; the shaft of the motor is provided with an eccentric shaft which is fixedly provided with a bearing; the output shaft of the oscillating maneuvering tool is connected with a working head clamping device; a driving part fixed on the output shat is matched with the bearing of the eccentric shaft. The output shaft and the driving part are connected and fixed by screw thread. As the output shaft of the oscillating maneuvering tool is connected with the driving part by screw thread, inner and outer screws can be produced just by general equipment, so the producing process is simple and the producing cost is low; in the assembling process, only a screwdriver such as a wrench is needed to be reliably connected with the two parts, so the operating process is simple and the efficiency is high.

Description

Reciprocally swinging formula power-driven tool

Technical field

The utility model relates to a kind of reciprocally swinging formula power-driven tool.

Background technology

The multipurpose reciprocally swinging formula power-driven tool that FEIN company produces, working head is that axis is done slightly swing with the output shaft, adopt interference fit between the hole of its output shaft and actuator, owing to limited by the casing inner space, assembling difficulty between output shaft and the actuator; Axle is had relatively high expectations with the magnitude of interference that cooperates between the hole, and the magnitude of interference is less, assembling easily but both skid easily, the magnitude of interference is bigger, and the assembling difficulty needs both matching parts are adopted fine finishining, processing cost height, the defective products that occurs in the production process also are difficult to maintenance; Simultaneously owing to adopt interference fit between output shaft and the actuator, it is less to pack tightly area, is difficult to transmit than high pulling torque, easily causes both to skid in the long-term use of instrument, causes the instrument work efficiency to reduce or damages.

Summary of the invention

The purpose of this utility model is: the reciprocally swinging formula power-driven tool that provides that a kind of requirement on machining accuracy is lower, assembling is simple easily, is difficult for skidding between output shaft and the actuator.

The utility model is achieved through the following technical solutions:

A kind of reciprocally swinging formula power-driven tool, be provided with the switch of motor and control motor in the casing, the rotating shaft of motor is provided with eccentric shaft, be fixed with bearing on the eccentric shaft, reciprocally swinging formula power-driven tool output shaft is connected with the working head clamping device, actuator is fixed on the output shaft and matches with bearing on the eccentric shaft, it is characterized in that: adopt thread connection to fix between described output shaft and actuator.

Advantage of the present utility model is: adopt thread connection between the output shaft of reciprocally swinging formula power-driven tool and the actuator, internal and external threads only need adopt general equipment just can process, and processing cost easy to manufacture is low; Only need to adopt spanner etc. to revolve tool in the assembling process and just can both be linked up reliably, simple to operate, the efficient height; Cooperate area bigger between the output shaft of thread connection and the actuator, only need between apply certain screw-down torque, screw-down torque just can the long-time normal operation of assurance instrument greatly greater than the output torque of motor.Because adopting thread connection to belong to dismoutability between the output shaft of reciprocally swinging formula power-driven tool and the actuator connects, can both be in production, maintenance and the product recycling process of instrument comparatively easily with both dismountings, reduce the machine maintenance cost, be convenient to resource reutilization.Bearing in the utility model also can be a bearing group.

In the utility model, additional adhesive attachment is fixed between described output shaft and the actuator.It can further improve the reliability of thread connection between the output shaft of reciprocally swinging formula power-driven tool and the actuator.Can prevent also that at screw thread place adhesive coating the instrument vibration from causing thread looseness.

In the utility model, the input of described actuator is a fork type.Certainly, the input of actuator also can be shaft hole mode.

Fig. 2 is that input of the present utility model is the actuator schematic diagram of fork type.

Fig. 3 is that input of the present utility model is the actuator schematic diagram of shaft hole mode.

The specific embodiment

As shown in Figure 1: the reciprocally swinging formula power-driven tool of present embodiment, be provided with the switch 2 of motor 3 and control motor in the casing 1, the rotating shaft of motor is provided with eccentric shaft 4, be fixed with bearing or bearing group 5 on the eccentric shaft 4, reciprocally swinging formula power-driven tool output shaft 9 is connected with the clamping device 11 of working head 12, and actuator 6 is fixed on the output shaft 9 and matches with bearing or bearing group 5 on the eccentric shaft 4.6 of output shaft 9 and actuators adopt thread connection to fix.

During work, eccentric shaft 4 is by fixing bearing or the bearing group 5 on it, the rotation of rotation motor 3 is converted into eccentric circular motion passes to actuator 6, drive end 7 on the actuator 6 matches with bearing or bearing group 5, union end 8 on the actuator 6 links with the connecting section 10 on the output shaft 9, drive output shaft 9 and make reciprocally swinging, output shaft 9 drives working head 12 by the working head clamping device on it 11 and makes reciprocally swinging.Adopt thread connection to fix among the figure between output shaft 9 and the actuator 6; Just the connecting section 10 of output shaft 9 and the union end 7 on the actuator 6 link, and adopt threaded connection mode to fix between the two.

In order further to improve the reliability of actuator 6 and output shaft 9 thread connection, it is loosening to prevent both, and on the flank of the connecting section 10 of output shaft 9 and the thread connection of the union end 8 of actuator 6, additional adhesive attachment is fixed, adhesive coating.When being output shaft 9 and actuator 6 employing thread connection, the also additional adhesive attachment of between is fixed.Add the compound connecting mode that gluing end connects by thread connection, can prevent more effectively that the instrument dither from causing both loosening inefficacies of connection.

For the ease of loading and unloading, can be convenient to the surface configuration of tool holdings such as spanner in the corresponding site setting of output shaft 9 and actuator, as flat side, gap, annular knurl etc.

Drive end on: the actuator 67 adopts fork type as shown in Figure 2, and it matches with bearing or bearing group 5, so that rotatablely moving of rotation motor is converted into the reciprocally swinging of output shaft 9 by them.

As shown in Figure 3: the drive end 8 on the actuator 6 adopts shaft hole mode, and it matches with bearing or bearing group 5, so that rotatablely moving of rotation motor is converted into the reciprocally swinging of output shaft 9 by them.

Motor in the utility model can be an electro-motor, also can be the motor of air motor or alternate manner.
