Description

Technical Field

[0001] This utility model relates to the field of tennis machine manufacturing technology, and in particular to an internal trimming device for a ball feed dial injection molded part. Background Technology

[0002] Tennis machines play an important role in tennis training and fitness. They mainly use a launching device to launch tennis balls from a storage tank to a specific area via a control unit. Through the cooperation of sensors and control units, they can launch balls with different forces and angles to different areas to achieve training and fitness effects.

[0003] Tennis machines are mostly made of injection-molded plastic parts, with the ball feed wheel being a key component. It primarily functions to position, control, and feed the ball. Generally produced by injection molding, the parting line of the feed wheel is prone to burrs and burrs. To ensure ball feeding accuracy and reduce interference with the tennis ball, the parting line needs to be effectively trimmed. The existing trimming method mainly involves workers manually cutting the parting line with scrapers, which is not only inconvenient and inefficient but also carries the risk of hand injuries from improper operation and cutting tools.

[0026] like Figure 1-6 The device shown is an internal trimming device for injection molded parts using a ball feed dial, comprising a worktable 1, a support device 2, a dial 3, a trimming mechanism 4, a pressing tube 5, and a limiting mechanism 6. The support device 2 is mounted on the top of the worktable 1, the dial 3 is secured to the outer side of the top of the support device 2, the trimming mechanism 4 and the limiting mechanism 6 are mounted on the surface of the worktable 1, and the pressing tube 5 is secured to the outer side of the top of the support device 2. The support device 2 includes a mounting tube 21, an adjusting rod 22, a limiting rod 23, a first spring 24, and a limiting insert rod 25. The mounting tube 21 is movably connected to the top of the worktable 1. The adjusting rod 22 is locked inside the top of the mounting tube 21, the limiting rod 23 is fixedly set at the bottom of the adjusting rod 22, the first spring 24 is sleeved outside the limiting rod 23, and the limiting insertion rod 25 is fixedly set at the top of the adjusting rod 22. The trimming mechanism 4 includes a motor 41, a turntable 42, an electric telescopic rod 43, and a tool assembly 44. The motor 41 is installed inside the top of the worktable 1, the turntable 42 is fixedly set at the output end of the motor 41, the electric telescopic rod 43 is installed inside the bottom of the turntable 42, and the tool assembly 44 is set at the telescopic end of the electric telescopic rod 43.

[0027] Specifically, the limiting mechanism 6 includes a guide box 61, a plug rod 62, a pressure plate 63, a guide rod 64, and a third spring 65. The guide rod 64 is fixedly installed inside the guide box 61, the third spring 65 is sleeved on the outside of the guide rod 64, the plug rod 62 is snapped inside the guide box 61, and the pressure plate 63 is fixedly installed outside the plug rod 62. The tool assembly 44 includes a mounting box 441, a tool holder 442, a scraper 443, a friction block 444, and a second spring 445. The mounting box 441 is fixedly installed at the telescopic end of the electric telescopic rod 43, the tool holder 442 is snapped inside one end of the mounting box 441, the scraper 443 is installed on one side of the tool holder 442, and the friction block 445... 44 is fixedly installed at the bottom of one end of the tool holder 442. The second spring 445 is installed inside one side of the mounting box 441 and between the back of the tool holder 442. The upper surface of the friction block 444 is horizontal, and the top of one end is inclined downward. The blade of the scraper 443 is inclined. A guide block is provided inside the mounting tube 21. A guide groove is vertically opened on the surface of the adjusting rod 22 to cooperate with it. A limiting block is provided at the end of the insertion rod 62 to cooperate with the guide groove on the surface of the adjusting rod 22. A limiting groove is opened on the surface of the limiting insertion rod 25. The cross section of the limiting insertion rod 25 cooperates with the mounting hole in the middle of the dial wheel 3. An insertion hole is opened at the bottom of the pressing tube 5 to cooperate with the limiting insertion rod 25.

[0028] In this embodiment, the dial wheel 3 is first fitted onto the top of the limiting rod 25 according to the mounting hole in its middle. The end of the limiting rod 25 passes through and extends to the outer side of the top of the dial wheel 3. Then, the bottom insertion hole of the pressing tube 5 is locked onto the top of the limiting rod 25 and pressed down until the adjusting rod 22 retracts downward. The first spring 24 is compressed and retracts until the limiting rod 23 contacts the bottom of the mounting tube 21. In this way, the distance from the bottom of the dial wheel 3 to the upper surface of the workbench 1 is constant. Then, the handle at one end of the rod 62 is released. Under the action of the third spring 65, the third spring 65 applies pressure to the pressure plate 63, so that the limiting block at the end of the rod 62 is locked in the guide groove on the surface of the adjusting rod 22, preventing the adjusting rod 22 from rotating. At this time, the trimming mechanism 4 will be at the bottom of the dial wheel 3 ball ring.

[0029] Furthermore, the rotation of motor 41 controls the rotation of turntable 42. During the rotation, electric telescopic rod 43 slowly extends, and at this time, tool assembly 44 pushes forward. First, friction block 444 contacts the bottom of ball ring of dial wheel 3. One end of friction block 444 is set at an angle downward. The rotating friction block 444 grinds the bottom of ball ring and effectively removes burrs. As electric telescopic rod 43 continues to push forward, the inclined scraper 443 effectively cleans the burrs on the inner side of the bottom of ball ring. Turntable 42 is provided with a material discharge hole at the bottom to facilitate the discharge of waste. The second spring 445 retracts when the scraper 443 is excessively squeezed to avoid damage to dial wheel 3. After the bottom of ball ring of a single dial wheel 3 is processed, the pressing tube 5 is lifted, so that adjusting rod 22 is lifted under the action of first spring 24, and dial wheel 3 is lifted synchronously to avoid interference with trimming mechanism 4 when adjusting dial wheel 3. Rotating mounting tube 21 can adjust the angle of dial wheel 3, switch the processed ball ring, and press again to clamp and limit, achieving the effect of rapid adjustment processing.
