[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a clamping fixture for the production of mechanical parts.

[0025] This utility model provides, for example Figure 1-3The clamping fixture for producing mechanical parts shown includes a base 1. The base 1 has a first cavity inside, and through holes are symmetrically opened on both sides of the cavity. A moving rod 2 is slidably arranged inside each of the two through holes. A driving mechanism is arranged inside the first cavity. Both moving rods 2 are moved by the driving mechanism. One end of each moving rod 2 is fixedly connected to an L-shaped rod 3. One end of each L-shaped rod 3 is fixedly connected to a pressure plate 4. Multiple sliding grooves are opened on one side of each pressure plate 4. A pressure block 5 is slidably arranged inside each sliding groove. A second cavity is opened inside each second cavity. A fixing mechanism is arranged inside each second cavity. Each pressure block 5 is fixed by a corresponding fixing mechanism.

[0026] When it is necessary to press irregular mechanical parts, the position of each pressing block 5 can be adjusted according to the shape of the mechanical parts, so that each pressing block 5 fits the mechanical parts during the pressing process, thereby improving the stability of the pressing.

[0027] In order for the two pressure plates 4 to be movable, such as Figure 1-2 As shown, the drive mechanism includes a rotating rod 6, a gear 7, two racks 8, a movable plate 9, and a motor 10. The rotating rod 6 is rotatably connected to the inside of the first cavity. The gear 7 is fixedly sleeved on the corresponding rod wall of the rotating rod 6. The two racks 8 are respectively meshed with the two ends of the gear 7. The two movable plates 9 are respectively fixedly connected to one end of the corresponding rack 8. Each movable rod 2 is respectively fixedly connected to one side of the corresponding movable plate 9. The motor 10 is fixedly connected to one side of the base 1. One end of the rotating rod 6 passes through one side of the first cavity and is fixedly connected to the output end of the motor 10.

[0028] Start the motor 10 to make the rotating rod 6 rotate. Then the two racks 8 drive the corresponding moving plates 9 to move closer to each other, so that the two moving rods 2 can drive the corresponding pressure plates 5 to move closer to each other and clamp the mechanical parts.

[0029] In order to ensure that each pressure block 5 can be fixed after being moved, such as Figure 1-3 As shown, the fixing mechanism includes multiple square blocks 11, multiple baffles 12, multiple connecting rods 13, multiple buttons 14, and multiple springs 15. Each second cavity has a square hole on its upper surface. Each square block 11 is slidably disposed inside the corresponding square hole. Each baffle 12 is fixedly connected to the lower surface of the corresponding square block 11. Each spring 15 is disposed inside the corresponding second cavity and fixedly connected to the corresponding baffle 12. Each connecting rod 13 is fixedly connected to the upper surface of the corresponding square block 11. Each button 14 is fixedly connected to the upper end of the corresponding connecting rod 13. Each slide has a strip hole on its upper surface. Each strip hole matches the corresponding connecting rod 13. Each strip hole has multiple fixing holes inside it. Each fixing hole matches the corresponding square block 11.

[0030] Press button 14 to move square block 11 out of the corresponding fixing hole. During this process, baffle 12 squeezes spring 15 and compresses it. Then, move connecting rod 13 to move pressure block 5. When pressure block 5 moves to the designated position, release button 14. Then spring 15 rebounds and drives square block 5 to move into another fixing hole, so that each pressure block 5 can be fixed after moving.

[0031] To protect mechanical parts, such as Figure 1-2 As shown, a rubber pad 16 is fixedly connected to one end of each pressure block 5.

[0032] The rubber pad 16 can be used to protect the mechanical parts from excessive pressure.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
