[0005] According to another embodiment of the utility model, the annular elastic member is further comprised of an annular rubber member, a cavity is provided in the annular elastic member, and the cavity is communicated with the outlet of the air inlet hole.

[0006] According to another embodiment of the present invention, the clamping block is made of phenolic polymer, and the bottom end of the clamping block is fixed on the machine base.

[0007] According to another embodiment of the utility model, the elastic support member is further comprised of a spring.

[0008] According to another embodiment of the utility model, the clamping member is further comprised of a pin.

[0009] According to another embodiment of the present invention, the connecting groove is further comprised of a circular groove.

[0010] The beneficial effect of the utility model is that the utility model uses an air pump to inflate the inside through the air inlet, and then uses the airflow to drive the annular elastic member to deform, thereby driving the annularly distributed clamping blocks to clamp the product. The elastic support member cooperates with the clamping member to clamp the slot at the bottom of the product, thereby helping to locate the direction of the product. The application reduces the volume and cost and simplifies the structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a structural schematic diagram of the utility model; Figure 2 It is a cross-sectional view of the utility model; Figure 3 It is a structural schematic diagram of the utility model after clamping the product.

[0017] Combined with Figure 1 and attached Figure 2 As shown, a pneumatic chuck for product processing includes a machine base 1, an annular elastic member 2, an air inlet 3, a clamping block 4, an elastic support member 5, and a clamping member 6. The machine base 1 is provided with a connecting groove 7 for connecting the product, the bottom of the connecting groove 7 is connected to the clamping member 6 through the elastic support member 5, the side wall of the connecting groove 7 is connected with an annular elastic member 2, the connecting groove 7 is connected with several clamping blocks 4 formed in a ring shape, the annular elastic member 2 is located between the clamping block 4 and the side wall of the connecting groove 7, and the machine base 1 is provided with an air inlet 3.

[0018] The annular elastic member 2 is an annular rubber member. A cavity is provided in the annular elastic member 2 . The cavity is communicated with the outlet of the air inlet 3 .

[0019] The material of the clamping block 4 is phenolic polymer, and the bottom end of the clamping block 4 is fixed on the machine base 1 .

[0020] The elastic supporting member 5 is a spring.

[0021] The clamping member 6 is a pin.

[0022] The connecting groove 7 is a circular groove.

[0023] As attached Figure 3 As shown, the use of the present application is as follows: first, put the product into the connection groove 7 of the base 1, and let the horizontal clamping member 6 be embedded in the V-shaped groove 7 at the bottom of the product. After the product and the clamping member 6 are connected together, the horizontal orientation of the product can be positioned. Since the elastic support member 5 provides support force for the clamping member 6, the elastic support member 5 can press the clamping member 6 upwards and tightly in the V-shaped groove 7. After the product presses down the elastic support member 5, the clamping block 4 starts to clamp the product.

[0024] The air pump is connected to the air inlet 3, and air is inflated into the machine base 1 through the air inlet 3. The rubber annular elastic member 2 is deformed and bulges inward. The annular elastic member 2 can push the plurality of clamping blocks 4 formed in an annular shape and made of phenolic polymer inward, thereby clamping the product.

[0025] When the product needs to be released after the processing task is completed, the compressed air is released, and then the annular elastic member 2 retracts, and the clamping block 4 made of phenolic polymer shrinks back to its original shape by elastic deformation, and the pneumatic chuck releases the product.

[0026] When the pneumatic chuck releases the product, the elastic deformation of the elastic support member 5 is released, and finally the product is ejected from the pneumatic chuck, and the process is completed.
