[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a pin-type workpiece assembly tool, including an assembly cylinder, and an installation tube is fixedly connected to the port of the assembly cylinder.

[0008] A workpiece fixing assembly includes a plurality of support rods that are slidably connected to the side wall of a mounting tube. Each of the support rods located inside the mounting tube has a clamping plate fixedly connected to its end. A compression spring is fixedly connected between each clamping plate and the inner wall of the mounting tube.

[0009] An auxiliary assembly component includes an annular rotating bracket fixedly connected to the inner wall of an assembly cylinder.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: Refer to Figures 1 to 3 A pin-type workpiece assembly tool includes an assembly cylinder 1, a workpiece fixing assembly, and an auxiliary assembly assembly. A straight handle 13 is fixedly connected to the end of the assembly cylinder 1 away from the mounting tube 2, and the mounting tube 2 is fixedly connected to the port of the assembly cylinder 1. The workpiece fixing assembly includes a plurality of support rods 3 that are slidably connected to the side wall of the mounting tube 2. Each of the support rods 3 located inside the mounting tube 2 has a pressing and fixing plate 4 fixedly connected to its end. The pressing and fixing plate 4 has an arc-shaped structure, and the edges of the upper and lower end faces of the pressing and fixing plate 4 are rounded. A compression spring 5 is fixedly connected between each pressing and fixing plate 4 and the inner wall of the mounting tube 2.

[0026] During the process of inserting the pin-type workpiece into the installation tube 2, it will squeeze several clamping and fixing plates 4, causing several compression springs 5 ​​to start compressing and accumulating elastic potential energy. After the pin-type workpiece is inserted, the several compression springs 5 ​​will release potential energy to elastically push the clamping and fixing plates 4, so that the clamping and fixing plates 4 can elastically press the pin-type workpiece in the opposite direction, thereby quickly fixing the pin-type workpiece and improving the efficiency of the assembly tool in fixing the pin-type workpiece.

[0027] Reference Figure 1 and Figure 3The auxiliary assembly components include an annular rotating bracket fixedly connected to the inner wall of the assembly cylinder 1, a lifting screw 6 rotatably connected to the annular rotating bracket, a limit lifting block 7 threadedly connected to the lifting screw 6, a strip-shaped limit guide rail 11 fixedly connected to the inner wall of the assembly cylinder 1, a groove opened on the limit lifting block 7, the strip-shaped limit guide rail 11 matching the groove, two arc-shaped guide rods 8 fixedly connected to the lower end face of the limit lifting block 7, an abutment 9 fixedly connected to the lower end of the two arc-shaped guide rods 8, a self-driving component fixedly connected to the inner wall of the assembly cylinder 1, the self-driving component including an annular fixed bracket fixedly connected to the inner wall of the assembly cylinder 1, a rotary motor 10 fixedly connected to the inner side of the annular fixed bracket, the output end of the rotary motor 10 fixedly connected to the upper end of the lifting screw 6 through a coupling, a control panel 12 fixedly connected to the outer peripheral wall of the assembly cylinder 1, and the control panel 12, the rotary motor 10 and the external power supply are electrically connected to form a whole.

[0028] The rotary motor 10 is started by the control panel 12. The rotary motor 10 drives the lifting screw 6 to rotate, so that the limit lifting block 7 begins to move downward inside the assembly cylinder 1. The arc-shaped guide rod 8 drives the abutment 9 to move downward, and the downward movement of the abutment 9 can automatically push the pin-type workpiece, so as to facilitate and quickly detach the pin-type workpiece from the installation tube, which helps to improve the ease of use of the pin-type workpiece assembly tool.

[0029] The working principle of this utility model is as follows:

[0030] 1. In use, first insert the pin-type workpiece into the center position of several clamping and fixing plates 4 inside the mounting tube 2. During this process, the pin-type workpiece will squeeze the clamping and fixing plates 4, causing several compression springs 5 ​​to start compressing and accumulating elastic potential energy. After the pin-type workpiece is inserted, the compression springs 5 ​​will release potential energy to elastically push the clamping and fixing plates 4, so that the clamping and fixing plates 4 can elastically press the pin-type workpiece in the opposite direction, thereby quickly fixing the pin-type workpiece and improving the efficiency of the assembly tool in fixing the pin-type workpiece.

[0031] 2. When assembling and using pin-type workpieces, it is necessary to push the pin-type workpiece to move in order to separate the pin-type workpiece from the assembly tool and insert the pin-type workpiece into the corresponding mechanical structure. The rotary motor 10 can be started by the control panel 12. The rotary motor 10 drives the lifting screw 6 to rotate, so that the limit lifting block 7 begins to move downward inside the assembly cylinder 1. The arc-shaped guide rod 8 drives the abutment 9 to move downward, and the downward movement of the abutment 9 can automatically push the pin-type workpiece, so as to facilitate and quickly separate the pin-type workpiece from the installation tube, which is beneficial to improving the ease of use of the pin-type workpiece assembly tool.
