[0028] According to the overall structure of the device, a groove is provided on the top of the base 2, and the limiting effect of the spring 204 and the connecting rod 205 is used. After the downward pressure is applied to the pressing plate 3, the elasticity of the spring 204 itself is used to reset. A mounting opening is provided in the positioning block 201, and the pin can be placed in the mounting opening in the positioning block 201 in advance for preliminary fixation. When the hole groove of the surface to be processed is flipped to the bottom of the mounting opening, fine-tuning and alignment are performed. At this time, a force can be applied to the pressing plate 3 to squeeze the pin in the mounting opening of the positioning block 201 downward into the hole groove of the workpiece to be processed through the nail-shaped plate 302. The driving gear 1001 is driven to rotate by shaking the rocker 7. Due to the two sides of the rack 601 The two sides are respectively meshed with the driving gear 1001 and the auxiliary gear 801. When the driving gear 1001 rotates, the auxiliary gear 801 can be driven to rotate. The other end of the rotating roller 8 is fixedly connected to the rotating disk.

[0029] like Figure 1-3 As shown, a circular groove is opened on one side of the base 2, and a storage tube 202 is fixedly connected to the inner wall of the circular groove, the storage tube 202 is a hollow tube, and the top of the storage tube 202 is fixedly connected to a limiting pile 203, the positioning block 201 is made of rubber material, a spring 204 is fixedly connected to the bottom of the storage tube 202, and a connecting rod 205 is sleeved inside the spring 204, a pressing plate 3 is fixedly connected to the top of the connecting rod 205, and an anti-slip pad 301 is fixedly connected to one end of the pressing plate 3, and a nail-shaped plate 302 is fixedly connected to the bottom of one end of the pressing plate 3.

[0030] By opening a circular groove at the top of the base 2, the spring 204 and the connecting rod 205 can move up and down in the storage tube 202 through the limiting effect. After applying downward pressure to the pressing plate 3, the elasticity of the spring 204 itself is used to reset inside the storage tube 202.

Due to the strong plasticity of the rubber material, one end of the bottom of the pin will move along one end of the outer wall of the workpiece to be processed during the rotation of the workpiece until it is aligned with the circular groove on the surface. When fine-tuning and aligning, a force can be applied to the pressing plate 3 at this time to squeeze the pin in the positioning block 201 downward into the hole groove of the workpiece to be processed through the nail-shaped plate 302.

[0031] like Figure 4-5 As shown, a nailing hole is provided on one side of the top surface of the base 2, and the nailing hole on one side of the top surface of the base 2 is parallel to and coincides with the nailing hole on the surface of the positioning block 201, a through hole is provided at the center of one side surface of the workbench 1, and a rotating roller 8 is rotatably connected inside the through hole, a clamping plate 9 is rotatably connected at one end of the rotating roller 8, and a plurality of movable grooves are provided on the surface of the clamping plate 9, the movable groove is a T-slot, and a slider 901 is slidably connected inside the movable groove, one side of the clamping plate 9 is fixedly connected to the workbench 1, a group of relative limiting strips 902 are fixedly connected at the opening of the movable groove, and the inner wall of the limiting strip 902 is slidably connected to the slider 901, the slider 901 is an inverted T-shaped block, and a toggle roller 903 is fixedly connected to the center of the surface of the slider 901, one end of the rotating roller 8 is fixedly connected to a rotating plate 4, and a plurality of arc grooves are provided on the surface of the rotating plate 4, and the toggle roller 903 passes through the arc groove and is fixedly connected to the clamping block 5, and the clamping block 5 is an arc block.

[0032] By opening a nailing hole on the surface of the base 2 and the nailing hole of the base 2 and the nailing hole of the positioning block 201 are parallel to each other, a certain movable distance is given to the pin to facilitate alignment with the hole groove, and one end of the rotating roller 8 that passes through the inside of the workbench 1 is rotatably connected to the clamping plate 9, and the clamping plate 9 is fixedly connected to the workbench 1, and a movable groove is opened on the surface of the clamping plate 9, and a slider 901 is slidably connected in the movable groove, and a group of relative limit strips 902 are fixedly connected at the opening of the movable groove, on the one hand, leaving movable space for the toggle roller 903 at the bottom of the slider 901, and on the other hand, it is ensured that the slider 901 is locked in the movable groove and will not fall out during the movement process. One end of the rotating roller 8 is fixedly connected to the rotating plate 4, and when the rotating roller 8 is rotated, the rotating plate 4 will be driven to rotate together, and a plurality of arc grooves are opened on the surface of the rotating disk, which will drive the toggle roller 903 to move along the arc groove during rotation, so that the slider 901 moves inside the movable groove, thereby realizing the contraction and expansion of the clamping block 5 at the top of the toggle roller 903.

[0033] like Figure 6 As shown, the slide groove 6 is a T-shaped groove, and the rack 601 is a T-shaped long strip plate. The slide groove 6 is slidably connected to the rack 601, and serrations are provided on both sides of the rack 601. The other end of the rotating roller 8 is fixedly connected to an auxiliary gear 801, and the auxiliary gear 801 is meshed with one side of the rack 601. One side of the workbench 1 is fixedly connected to a cylindrical rod 10, and the outer wall of the cylindrical rod 10 is rotatably connected to a driving gear 1001, and one side of the driving gear 1001 is fixedly connected to the rocker 7, and the driving gear 1001 is meshed with the other side of the rack 601.

[0034] By opening a T-shaped slide groove 6 on one side of the workbench 1, and the slide groove 6 is slidably connected to the T-shaped rack 601, the rack 601 is locked in the slide groove 6 during the up and down movement. A plurality of saw teeth are provided on both sides of the rack 601, and the two sides of the gear are respectively meshed with the driving gear 1001 and the auxiliary gear 801.

[0035] Working principle: When it is necessary to install a pin on the workpiece to be processed, the pin can be inserted into the nail hole opened in the positioning block 201 in advance, and the pin can be retained inside the nail hole by the anti-slip property of the rubber. At this time, the driving gear 1001 can be driven by the rocker 7 to rotate clockwise to drive the rack 601 downward, and the rack 601 drives the auxiliary gear 801 to rotate counterclockwise, and the auxiliary gear 801 drives the rotating roller 8 to rotate counterclockwise. At this time, the toggle roller 903 will be driven to move along the arc groove during the rotation process, so that the slider 901 moves inside the movable groove, realizing the contraction of the clamping block 5 on the top of the toggle roller 903, and the clamping effect can be released, and the workpiece to be processed can be placed on the clamping block 5 outer wall, manually flip the workpiece to be processed. Due to the strong plasticity of rubber material, it will rotate along one end of the outer wall of the workpiece to be processed during its rotation until it is aligned with the circular groove on the surface. When fine-tuning the alignment, a force can be applied to the pressing plate 3 to squeeze the pin in the positioning block 201 downward into the hole groove of the workpiece to be processed through the nail-shaped plate 302. The connecting rod 205 at the top of the pressing plate 3 is reset inside the storage tube 202 under the action of the spring 204. At this time, the work of installing the pin in a hole groove has been completed. The rocker 7 can be turned again to release the clamping effect and flip the workpiece to be processed to align it. Continuing the above steps can complete the installation of the pin in the workpiece to be processed.
