[0026] Example 1:

[0027] like Figure 1-4As shown, a processing jig with a T-block 5 for side clamping includes a base plate 1, a positioning block 8, a power unit and two clamping units. The positioning block 8 is fixed at the center above the base plate 1 and is used to support the workpiece. The two clamping units are respectively arranged on both sides of the positioning block 8. The power unit is arranged below the base plate 1 and is used to drive the two clamping units to clamp the workpiece; the clamping unit includes a pressing block 3 and a T-block 5. The pressing block 3 is provided with an arc groove that cooperates with the outer wall of the workpiece toward the side of the positioning block 8, and the pressing block 3 is provided with a T-slot on the side relative to the positioning block 8. The T-block 5 is fitted in the T-slot, and the T-block is tilted downward toward the side of the positioning block 8; the T-slot is tilted upward toward the side of the T-block 5.

[0028] There are positioning holes on both sides of the positioning block 8, and positioning pins 7 are provided in the positioning holes. The bottom of the positioning pin 7 is connected to the base plate 1 through a spring, and the positioning pin 7 cooperates with the inner hole of the workpiece; the positioning pin 7 is inserted into the inner hole of the workpiece to position the product to improve the clamping accuracy.

[0029] The power unit includes a cylinder 12 and a pull plate 10. The cylinder 12 is fixed below the base plate 1. The pull plate 10 is fixed to the top of the piston rod of the cylinder 12. Both sides of the pull plate 10 are fixed to the bottom of the two T-blocks 5 respectively.

[0030] A guide post 11 is fixed on the bottom plate 1 , and the guide post 11 extends downward and passes through the pull plate 10 ; the guide post 11 plays a guiding role, ensuring that the pull plate 10 moves up and down smoothly and improves accuracy.

[0031] Both ends of the pressing block 3 are provided with pads 4, and the pads 4 are arranged between the pressing block 3 and the bottom plate 1; both ends of the pressing block 3 are provided with pressure strips 2, and both sides of the bottom of the pressing block 3 are provided with protrusions that cooperate with the pressure strips 2. The pressure strips 2 are fixed to the bottom plate 1 and are used to press the pressing block 3 on the pads 4; the top block and the pressure strips 2 are used to limit the pressing block 3 so that the pressing block 3 can only move horizontally.

[0032] Support columns 6 are provided on both sides of the positioning block 8, and the support columns 6 are fixed to the base plate 1. The support columns 6 cooperate with the limiting grooves, and the limiting grooves are set on the pressure block 3 and the grooves are set toward the positioning block 8; the support columns 6 are used to support the workpiece plane and keep the workpiece balanced.

[0033] An anti-stupidity pin 9 is provided on one side of the positioning block 8 and is fixed to the base plate 1 ; the anti-stupidity pin 9 is used to limit the workpiece and prevent the workpiece from being misplaced and installed on the positioning block 8 .

[0034] Working principle: The T-block 5 moves up and down under the action of the cylinder 12 and the pull plate 10, and the T-slot causes the pressure block 3 to move horizontally under the force of the T-block 5, thereby clamping and loosening the side of the workpiece. During this series of repeated movements, the guide pillars 11 and guide sleeves on the pull plate 10, as well as the pressure strip 2 and the pad 4 provide accuracy and stability during movement. The locating pin 7 limits the pressure block 3, so that the clamping force on the product is uniform and stable, thereby ensuring the processing accuracy of the workpiece.

[0035] The processing jig with the side clamping of the T-block 5 of the present invention uses the up and down movement of the T-block 5 with the side tilted arrangement to push the pressure block 3 towards or away from the workpiece, thereby achieving side clamping of the workpiece and solving the problem of no pressure point position on the workpiece.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
