Description

Technical Field

[0001] The utility model relates to the field of metal forging processing, in particular to a metal forging processing fixture. Background Art

[0002] Metal forgings are widely used in modern industry, often used to manufacture various mechanical parts due to their excellent mechanical and physical properties. However, during the processing of metal forgings, how to effectively fix and clamp the forgings to ensure machining accuracy, improve production efficiency, and ensure operator safety has always been a major technical issue.

[0003] Traditional clamps used to clamp metal forgings can only clamp metal forgings of specific shapes. Different metal forgings require different clamping equipment to clamp them. Replacing the clamp not only delays the processing efficiency of metal forgings, but also increases production costs due to multiple clamps. Utility Model Content

[0004] The utility model aims to solve the shortcoming of single function of the fixture for clamping metal forgings in the prior art and proposes a metal forging processing fixture.

[0005] In order to solve the problems existing in the prior art, the present invention adopts the following technical solutions:

[0012] Preferably, an arc-shaped groove is provided on the inner side of the clamping block, and a rubber pad is fixedly provided on the surface of the arc-shaped groove.

[0013] Preferably, the moving block fits against the inner wall of the fixed column groove, and a rotating ring is fixedly provided on one end of the bidirectional screw located outside the fixed column.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In the present invention, four symmetrical clamps are provided. The clamps are driven by the cylinder through the driving gear to drive the first tooth plate. When the four clamps operate synchronously, cylinders, disks and small metal forgings can be clamped. When a rectangular and oversized metal forging needs to be clamped, the adjustment component drives the two symmetrical driving gears away from the first tooth plate, causing the two clamping blocks to stop moving.

The rotation of the adjusting gear will cause the driving gear to rotate, allowing the driving gear to drive the clamping block to rotate toward the rear end of the fixed frame, making it easier for the two clamping blocks to clamp the metal forging.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example: This example provides a metal forging processing fixture, see Figure 1-4 Specifically, it includes a fixed frame 1, a limiting frame 11 is fixed to the end of the fixed frame 1, a movable plate 12 is slidably provided on the inner side of the limiting frame 11, and a first tooth plate 13 is fixed to the four surfaces of the movable plate 12, and a cylinder 14 is fixed to the inner wall of the fixed frame 1, and the output end of the cylinder 14 is fixedly connected to one end of the movable plate 12; an adjusting component is provided on one side of the fixed frame 1, and both sides of the limiting frame 11 and the adjusting component are rotatably provided with a driving gear 15 meshing with the first tooth plate 13; a connecting frame 5 is fixed on both sides of the limiting frame 11, and the connecting frame 5 is rotatably connected to the central axis of the two driving gears 15; a driving rod 16 is fixed on the driving gear 15, and a clamping block 17 is fixed at one end of the driving rod 16, and an arc groove is provided on the inner side of the clamping block 17, and a rubber pad is fixed on the surface of the arc groove; a flange 4 is fixed on the end of the fixed frame 1 away from the limiting frame 11;

[0025] The fixture can be connected to other driving equipment through the flange 4. Four clamping blocks 17 are arranged, and the clamping blocks 17 are symmetrically distributed in a rectangular shape. The movable plate 12 is driven to move by the cylinder 14, and the movable plate 12 drives the first tooth plate 13 to control the rotation of the four driving gears 15. The driving gear 15 drives the driving rod 16 and the clamping blocks 17 to rotate. Some small metal forgings such as cylinders and discs are clamped by the clamping blocks 17. When a rectangular and oversized metal forging needs to be clamped, the two symmetrical driving gears 15 are driven to leave the first tooth plate 13 through the adjusting component, so that the two clamping blocks 17 stop moving, and the metal forging is clamped by the other two clamping blocks 17, thereby improving the practicality of the fixture.

[0026] In the specific implementation process, Figure 1 and Figure 3As shown, the adjustment assembly includes a fixed column 2 installed on one side of the fixed frame 1, a bidirectional screw 21 is rotatably provided in the fixed column 2, two moving blocks 22 are slidably provided in the fixed column 2, the moving blocks 22 are threadedly connected to both ends of the bidirectional screw 21, one end of the moving block 22 is fixed with a connecting block 23, one end of the connecting block 23 is rotatably connected to the driving gear 15, the moving block 22 is fitted with the inner wall of the groove of the fixed column 2, the end of the bidirectional screw 21 located on the outside of the fixed column 2 is fixed with a swivel, a positioning block 6 is fixed on the fixed frame 1, and the fixed column 2 is installed in the groove of the positioning block 6;

[0027] By rotating the rotating ring, the bidirectional screw 21 is driven to rotate, and the bidirectional screw 21 drives the two moving blocks 22 to move synchronously along the fixed column 2. The moving block 22 drives the connecting block 23 to move, and the connecting block 23 drives the two driving gears 15 to move synchronously, so that the driving gear 15 engages or disengages with the first gear plate 13 to achieve control of the two clamps; the moving blocks 22 are respectively located at both ends of the fixed column 2 and also on both sides of the fixed frame 1, so that the two driving gears 15 are respectively located on both sides of the fixed frame 1, and are symmetrically distributed with the other two driving gears 15.

[0028] In the specific implementation process, Figure 3 and Figure 4 As shown, the central axis of the two driving gears 15 is fixed with an adjusting gear 3, and one side of the fixed column 2 is fixed with a support rod 31, and the end of the support rod 31 is fixed with a second gear plate 32;

[0029] When the two driving gears 15 are disengaged from the first tooth plate 13, the adjusting gear 3 on the central axis of the driving gear 15 will contact and mesh with the second tooth plate 32, and the adjusting gear 3 will be driven to rotate by the second tooth plate 32. Since the adjusting gear 3 and the driving gear 15 are located on the same central axis, the rotation of the adjusting gear 3 will cause the driving gear 15 to rotate, allowing the driving gear 15 to drive the clamping block 17 to rotate toward the rear end of the fixing frame 1, making it easier for the two clamping blocks 17 to clamp the metal forging.

[0030] Specifically, the working principle and operation method of the utility model are as follows:

[0031] The movable plate 12 is driven to move by the cylinder 14, and the movable plate 12 drives the first tooth plate 13 to control the rotation of the four driving gears 15. The driving gear 15 drives the driving rod 16 and the clamping block 17 to rotate, and the clamping block 17 is used to clamp some small metal forgings such as cylinders and disks. When a rectangular and oversized metal forging needs to be clamped; the bidirectional screw 21 is driven to rotate by rotating the swivel, and the bidirectional screw 21 drives the two moving blocks 22 to move synchronously along the fixed column 2, and the moving block 22 drives the connecting block 23 to move, and the connecting block 23 drives the two driving gears 15 to move synchronously, so that the driving gear 15 is disengaged from the first tooth plate 13, and the two symmetrical clamps clamp the metal forging.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
