[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution:
[0021] A screw locking fixture, including a fixture main body 1 for assisting in fixing screws. The fixture main body 1 includes a base 11, an operating table 12, a support block 13, a rotating plate 14, and a fixing block 15. The top of the base 11 is provided with an operating table 12 that is recessed. The top of the base 11 is fixedly connected to a fixing block 15. One side of the fixing block 15 is rotatably connected to a rotating plate 14 with a hollow middle. The top of the base 11 is fixedly connected to a support block 13 for supporting the rotating plate 14. The top of the operating table 12 is provided with a workpiece clamping mechanism 2. The workpiece clamping mechanism 2 includes a positioning strip 21, a slider 22, a guide rod 23, and a first spring 24. The base 11 is provided with a plurality of grooves 3. The guide rod 23 is fixedly connected to the groove 3 opened in the base 11. The outer side of the guide rod 23 is slidably connected to the slider 22. The top of the slider 22 is fixedly connected to the positioning strip 21. The outer side of the guide rod 23 is provided with a first spring 24. By providing the workpiece clamping mechanism 2 at the operating table 12, it is convenient to clamp and fix workpieces of different specifications, improving the overall versatility of the fixture main body 1. And compared with the existing technology of taking the positioning plate, it avoids the cumbersome process of taking and makes the fixing process more simple and fast.
[0022] One of the first springs 24 is arranged between the two sliders 22. The sliders 22 are slidably connected to the grooves 3 formed at the base 11, facilitating the clamping of the positioning strips 21. A part clamping mechanism 5 is provided at the rotating plate 14. The part clamping mechanism 5 includes a fixing plate 51, a sliding rod 52, a second spring 53 and a moving plate 54, facilitating the clamping and fixing of parts. A plurality of fixing plates 51 are fixedly connected to the top of the rotating plate 14. A sliding rod 52 is fixedly connected to one side of the fixing plate 51. A second spring 53 is arranged outside the sliding rod 52. A moving plate 54 with a T-shaped cross-section is slidably connected to the outside of the sliding rod 52. A rubber layer 4 is fixedly connected to one side of the moving plate 54 and the positioning strip 21, increasing the friction while not easily damaging the parts and workpieces. The second spring 53 is arranged between the fixing plate 51 and the moving plate 54. The moving plate 54 slides in the hollow part of the rotating plate 14, facilitating the movement of the moving plate 54.
[0023] Working process: When the screw locking fixture is in use, first place the fixture body 1 in a suitable position. The user holds the rotating plate 14 and rotates it backward to an open state. Then, place the workpiece to be fixed in turn on the surface of the operating table 12 and between the two positioning strips 21. Since the positioning strips 21 are fixedly connected to the sliders 22 and the sliders 22 move on the outside of the guide rod 23 and inside the groove 3, under the action of the elastic force of the first spring 24, the two positioning strips 21 effectively clamp the workpiece and fix the workpiece. After fixing the workpiece, rotate the rotating plate 14 in the reverse direction until the bottom of the rotating plate 14 fits against the support block 13. The support block 13 effectively supports the rotating plate 14. Then, pass the part through the hollow part of the rotating plate 14 and between the two moving plates 54 until the bottom of the part fits tightly against the positioning strip 21. The positioning strip 21 supports the part. Since the moving plate 54 slides on the outside of the sliding rod 52, under the action of the elastic force of the second spring 53, the moving plate 54 can effectively clamp and fix the part. By providing the rubber layer 4 on one side of the moving plate 54 and the positioning strip 21, the friction between the moving plate 54 and the part, and between the positioning strip 21 and the workpiece is increased, making it not easy to move during clamping and not easy to damage the surfaces of the part and the workpiece. By providing the workpiece clamping mechanism 2 at the operating table 12, it is convenient to clamp and fix workpieces of different specifications, improving the overall versatility of the fixture body 1. Compared with the existing technology of taking the positioning plate, it avoids the cumbersome process of taking and makes the fixing process more simple and fast. By providing the part clamping mechanism 5 at the rotating plate 14, it is convenient to clamp and fix parts of different specifications, further improving the overall versatility of the fixture body 1.
