[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 5 The present invention provides a mechanical parts processing flipping fixture, comprising: a base 1 and a clamping device 5 for clamping parts, a first support column 2 fixedly connected to the upper surface of the base 1, a second support column 3 fixedly connected to the upper surface of the base 1, and a flipping device 4 provided on the upper surface of the base 1.

[0032] In the embodiments of this utility model, please refer to Figures 1 to 3The flipping device 4 includes a support column 401, which is fixedly connected to the base 1. A connecting block 402 is fixedly connected to the upper surface of the support column 401. A motor 405 is fixedly connected to one side of the connecting block 402. A connecting rod 403 is rotatably connected to the side of the connecting block 402 away from the motor 405. The output end of the motor 405 is fixedly connected to the connecting rod 403. A rotating rod 415 is rotatably connected inside the second support column 3. The end of the rotating rod 415 away from the support column 401 is fixedly connected to the clamping device 5. A gear 414 is fixedly connected to one end of the support column 401. A rectangular plate 411 is fixedly connected to the side of the second support column 3 near the gear 414. A groove 412 is formed on the side of the rectangular plate 411 away from the second support column 3. A rack 410 is slidably connected to the inner wall of the groove 412. The rack 410 meshes with the gear 414. A connecting frame 409 is fixedly connected to the side of the rack 410 away from the rectangular plate 411. A slider 408 is slidably connected to the inner wall of the connecting frame 409. The slider 408 is rotatably connected to the connecting rod 403. This achieves the effect that when processing the other side of the part is required, the part can be automatically flipped without re-clamping it, thanks to the flipping device 4. A fixing ring 404 is fixedly connected to the side of the connecting block 402 near the motor 405. A protective cover 406 is movably connected to the inner wall of the fixing ring 404. The motor 405 is located inside the protective cover 406. When the motor 405 is working, it can be protected by the fixing ring 404 and the protective cover 406, reducing the impact of the external environment on the motor 405. The protective cover 406 has several heat dissipation holes 407 evenly distributed on its arc surface. This allows the heat generated by the motor 405 during operation to be dissipated through the heat dissipation holes 407, preventing damage to the motor 405 due to high temperatures. Several sliding balls 413 are fixedly connected to the inner wall of the slide groove 412, and are evenly distributed on its inner wall. This reduces the frictional resistance between the rack 410 and the inner wall of the slide groove 412 when the rack 410 slides within it.

[0033] In the embodiments of this utility model, please refer to Figure 1 , Figure 4 and Figure 5The clamping device 5 includes a connecting plate 51, which is fixedly connected to a rotating rod 415. A rotating shaft 52 is rotatably connected to the side of the first support column 2 closest to the second support column 3. Telescopic rods 53 are fixedly connected to the sides of the rotating shaft 52 and the connecting plate 51 that are close to each other. A fixing frame 54 is fixedly connected to the free end of the telescopic rod 53. A screw 55 is threaded through the upper surface of the fixing frame 54. A knob 56 is fixedly connected to one end of the screw 55, and a pressure plate 58 is rotatably connected to the end of the screw 55 away from the knob 56. This achieves the effect of fixing the position of parts with different lengths, widths, and thicknesses when clamping and fixing parts. Several arc grooves 57 are evenly distributed on the arc surface of the knob 56. This allows the user to place their finger in the arc groove 57 to rotate the knob 56 when rotating the screw 55 using the knob 56, preventing slippage during rotation. Several rubber strips 59 are fixedly connected to the lower surface of the pressure plate 58, and the rubber strips 59 are evenly distributed on the lower surface of the pressure plate 58. When the pressure plate 58 is used to press and fix the parts, the rubber strips 59 can increase the friction between the parts and the parts, and prevent the parts from sliding.

[0034] The working principle of the mechanical parts processing flipping fixture provided by this utility model is as follows: When it is necessary to process the parts, the workpiece is first clamped and fixed by the clamping device 5. During the processing, when it is necessary to process the other side or another angle of the parts, the motor 405 is started, and the output end of the motor 405 starts to rotate. The rotation of the output end of the motor 405 drives the connecting rod 403 to rotate synchronously. During this process, the support column 401 and the connecting block 402 provide support for the motor 405 and the connecting rod 403. When the connecting rod 403 starts to move in a circle with the output end of the motor 405 as the center, the connecting rod 403 rotates synchronously. The other end of the connecting rod 403 drives the slider 408 to slide on the inner wall of the connecting frame 409. When the slider 408 slides in the connecting frame 409, the circular motion of the connecting rod 403 is converted into the linear motion of the connecting frame 409 by the slider 408. When the connecting frame 409 moves in a straight line, the connecting frame 409 drives the rack 410 to slide horizontally in the groove 412 of the rectangular plate 411. When the rack 410 slides in the groove 412, the ball bearings 413 on the inner wall of the groove 412 reduce the frictional resistance between the rack 410 and the groove 412, and increase the transmission efficiency of the rack 410 in the groove 412. When the rack 410 slides, it drives the gear 414 on the second support column 3 to rotate via the rotating rod 415. The rotating rod 415 is supported by the second support column 3 during rotation, and simultaneously drives the connected disc 51 to rotate synchronously, thereby causing the parts fixed by the clamping device 5 to rotate as well. When the rotation reaches the set angle, the motor 405 is turned off, and the processing of the parts continues. When it is necessary to continue flipping the parts, the motor 405 is restarted, and the above steps are repeated. During this process, the fixing ring 404 and the protective cover 406 protect the motor 405, reducing the impact of the external environment on the motor 405. The heat dissipation holes 407 on the protective cover 406 dissipate the heat generated by the motor 405 in a timely manner, preventing the motor 405 from being damaged due to high temperature.

[0035] When machining parts, they need to be clamped and fixed. First, according to the length and width dimensions of the parts, extend the telescopic rods 53 on the rotating shaft 52 and the connecting plate 51 respectively. When the free ends of the two telescopic rods 53 move, they will drive the two fixed frames 54 to move closer to each other. When the two fixed frames 54 have moved enough to place the parts between them, stop extending the telescopic rods 53 and place the parts on the fixed frames 54. Then, turn the knob 56 on the screw 55 to drive the screw 55 to rotate. When turning the knob 56, the operator can place their fingers in the arc groove 57 on the arc surface of the knob 56 to rotate it, so as to avoid slippage when turning the knob 56. When the screw 55 rotates, its end pushes the pressure plate 58 below towards the component. As the pressure plate 58 contacts the component, continued rotation of the screw 55 causes the rubber strip 59 below the pressure plate 58 to elastically deform, increasing both the contact area and friction between them to prevent the component from sliding under the pressure plate 58. Once the component is secured, processing can begin. When clamping and securing components of different sizes and thicknesses, reverse the knob 56 to release the pressure plate 58 from the component. Then, follow the same steps to clamp and secure another component without changing the fixture, improving the tooling's versatility.
