[0018] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.

[0019] This application discloses a positioning and clamping device for drilling holes in injection-molded parts of a tennis machine magnet bracket, referring to... Figure 2-4The system includes a frame 1, a divider 2, a turntable 3, and two positioning and clamping mechanisms. The divider 2 is installed at the bottom of the frame 1, and the turntable 3 is located at the top of the frame 1 and is driven by the divider 2. The two positioning and clamping mechanisms are symmetrically arranged on the turntable 3. Each positioning and clamping mechanism includes a clamping assembly 4 and a pressing assembly 5. The clamping assembly 4 includes a servo motor 41, a square frame 42, a transmission screw 43, and clamping rods 44. The servo motor 41 and the square frame 42 are both fixed on the turntable 3. The transmission screw 43 is rotatably connected inside the square frame 42. The two sides of the surface of the transmission screw 43 are provided with threaded grooves with opposite directions. The number of clamping rods 44 is set to two, and the two clamping rods 44 are symmetrically threadedly connected to the transmission screw 43. The servo motor 41 is used to drive the transmission screw 43 to rotate.

[0020] The clamping component 5 is set corresponding to the square frame 42. The clamping component 5 includes a clamping cylinder 51 and a push block 52. The clamping cylinder 51 can drive the push block 52 to push the injection molded part of the tennis machine magnet bracket onto the square frame 42. The turntable 3 has a clearance hole on its surface corresponding to the position of the positioning and clamping mechanism.

[0021] Reference Figure 3-4 A sliding groove is provided inside the square frame 42, and the clamping rod 44 is slidably disposed in the sliding groove. A stop plate 421 is provided at one end of the square frame 42 corresponding to the push block 52.

[0022] Reference Figure 3 A nozzle 6 is also provided on the turntable 3 on one side of the positioning and clamping mechanism. Compressed air is connected to the nozzle 6. Several chip removal grooves 31 are opened on the surface of the turntable 3.

[0023] By providing nozzles 6, the waste chips on the surface of the turntable 3 can be blown away from the chip discharge groove 31 after the part is picked up, so that a new tennis machine magnet bracket injection molded part can be placed.

[0024] The implementation principle of the positioning and clamping device for drilling injection molded parts of tennis machine magnet brackets in this embodiment is as follows:

[0025] The turntable 3 is equipped with two positioning and clamping mechanisms. Driven by the divider 2, drilling can be carried out at one station while loading and unloading can be carried out at the other station, thus enabling continuous drilling and high production efficiency. The structure of the positioning and clamping mechanism is also relatively simple and easy to use. During positioning, the operator only needs to insert the annular groove in the injection molded part into the clamping rod 44. Then, the servo motor 41 drives the transmission rod to rotate, and the transmission rod drives the two clamping rods 44 to move to both sides respectively, clamping the injection molded part from the inside of the annular groove. The clamping cylinder 51 drives the push block 52 to push the injection molded part against the square frame 42 from the side of the injection molded part, thus completing the positioning and clamping of the injection molded part. The installation is relatively simple.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
