Description

Technical Field

[0001] The utility model relates to the technical field of clamping tooling, in particular to a non-destructive clamping tooling. Background Art

[0002] Semiconductor system products have very high requirements for shape and position tolerances and appearance. The existing technology requires a reliable processing technology and a multi-axis machine with high precision for one-time clamping and molding to meet these requirements. In particular, for the particularity of product raw materials and the processing of parts with high requirements for surface flatness and contour, a clamping tool is needed to clamp them.

[0003] In the prior art, during the use of an existing clamping tool, if there is a perforation on the product, if a suction cup tool with a sealing ring is used, the suction force of the suction cup is very small and the parts cannot be scratched. If a vise is used for clamping, the flatness and scratches of the product cannot be controlled, which leads to a long processing cycle and debugging time, high cost, low efficiency, and unstable product quality. Utility Model Content

[0004] The utility model mainly provides a non-destructive clamping tool which can effectively control shape and position tolerances, and will not cause scratches on products due to clamping problems. The processing time and processing cycle are shortened, the processing cost is reduced, the efficiency is improved, the product quality is stable, the product defective rate is reduced, and the operating cost is effectively controlled.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a damage-free clamping tool, including a base plate, a main board is installed on the top of the base plate, an air pressure cavity is opened on the top of the base plate, an air suction port is opened at one end of the base plate, one end of the air suction port is connected with the air pressure cavity, an air pipe joint is installed at the other end of the air suction port, a sealing strip is provided on the outside of the air pressure cavity between the base plate and the main board, a plurality of connecting holes are opened in the main board, and a product body is placed on the top of the main board.

[0006] Preferably, screws are provided at the four corners of the main board, and first screw holes matching the screws are provided in the main board and the base plate. By setting the screws and the first screw holes, the main board can be installed on the base plate at any time and can also be disassembled at any time.

[0007] Preferably, a positioning pin is installed in the connecting hole in the main board, and the product body is positioned and placed on the top of the main board by the positioning pin. By installing the positioning pin in the connecting hole in the main board, the product body can be positioned and guided to avoid movement during processing. In addition, by providing multiple connecting holes, users can install corresponding positioning pins in different connecting holes according to the positions of the through holes on the product, which is more practical.

[0008] Preferably, sealing grooves matching the sealing strips are provided at opposite ends of the bottom plate and the main board, and the sealing strips are fixed in the sealing grooves provided at the top of the bottom plate. The setting of the sealing strips can prevent air leakage in the air pressure cavity after the bottom plate and the main board are installed, thereby preventing air from being sucked in from the connecting holes.

[0009] Preferably, second screw holes are provided at the four corners of the bottom plate, and the second screw holes facilitate installation of the bottom plate with other external devices.

[0010] Preferably, one end of the air pipe joint away from the air suction port is arranged outside the bottom plate, and the bottom end of the connecting hole is connected with the air pressure chamber. The bottom end of the connecting hole is connected with the air pressure chamber. When the air in the air pressure chamber is sucked in, the air will be sucked in through the connecting hole, thereby adsorbing the product placed on the top of the connecting hole.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] In the utility model, the material used for the main board is POM plastic, which has a certain hardness and can protect the product from being scratched. The flatness of the main board should be controlled within 0.005mm, which can not only ensure good adsorption to the product body but also effectively ensure the flatness requirement of the product body. By installing positioning pins in the connecting holes in the main board, the product body can be positioned and guided to avoid movement during processing. In addition, through the provision of multiple connecting holes, the user can install the corresponding positioning pins in different connecting holes according to the positions of the through holes on the product, which is more practical. Through the provision of sealing strips, air leakage in the air pressure cavity can be prevented after the bottom plate and the main board are installed, resulting in air not being sucked from the connecting holes.
