Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal part processing, in particular to an adjustable fixture for sheet metal part production. Background Technique

[0002] As is well known, sheet metal is a comprehensive cold working process for metal sheets, and the products processed by the sheet metal process are called sheet metal parts, and fixtures are required for fixing during the processing and production of sheet metal parts; as the prior art of the fixture for sheet metal part production, the Chinese patent (authorization announcement number: CN219805981U) discloses a workpiece fixture for sheet metal part processing and production, including a trapezoidal seat, a sector seat and a rotating seat. A knob one is arranged through the interior of the trapezoidal seat. The sector seat is installed through a shaft rod inside the trapezoidal seat. Sector scales are arranged at the front end and the rear end of the sector seat. A limiting gear is arranged above the rear end of the sector seat. The rotating seat is installed on the top of the sector seat through a rotating shaft. A threaded sleeve is fixedly installed on the other side of the top of the rotating seat. A lead screw two is installed through the interior of the threaded sleeve. A moving clamping block is arranged on one side of the lead screw two through a rotating shaft. Through the cooperation of the sector seat, the rotating seat and the limiting gear, the utility model can facilitate the staff to adjust the fixing angle of the sheet metal part. When the staff needs to further adjust the clamping direction of the sheet metal part, the rotating seat can be rotated to a specified angle and then the limiting bolt can be tightened to fix the limiting gear, so as to fix the rotating seat, facilitate the adjustment of the fixing direction of the sheet metal part, and increase the adjustability of the device;

[0003] However, the existing fixture mainly clamps the sheet metal part by tightening the lead screw. Due to the lack of the function of adaptively adjusting and clamping trapezoidal sheet metal parts with different heights, the stability of the trapezoidal sheet metal part after being clamped by the fixture still needs to be improved. Therefore, an adjustable fixture for sheet metal part production is proposed. Summary of the Invention

[0004] The purpose of the utility model is to provide an adjustable fixture for sheet metal part production to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: An adjustable fixture for sheet metal part production, including a base, a clamping mechanism and a trapezoidal sheet metal part, and the trapezoidal sheet metal part is installed on the base;

[0006] The clamping mechanism includes a bracket fixedly connected to the top of the base. A cylinder is fixedly installed at the top of the bracket. The piston rod of the cylinder penetrates the bracket and is rotatably connected to a gear. One side of the gear is meshed with a first rack, and the other side of the gear is meshed with a second rack. Movable blocks are fixedly connected to the opposite sides of the second rack and the first rack. Connecting rods are evenly slidably connected inside the movable blocks. One end of the top of the connecting rod is fixedly connected to the bracket. Connecting blocks are fixedly connected to the bottoms of the second rack and the first rack. Fixed blocks are fixedly connected to the bottoms of the connecting blocks, and both of the fixed blocks are located above the trapezoidal sheet metal part.

[0007] As a further preference of this technical solution: Anti-sliding blocks are evenly and fixedly connected to the bottom of the fixed block.

[0008] As a further preference of this technical solution: A stop block is fixedly connected to one end of the bottom of the connecting rod.

[0009] As a further preference of this technical solution: Support blocks are evenly and fixedly connected to the outside of the base. Threaded rods are threadedly connected inside the support blocks.

[0010] As a further preference of this technical solution: A convex block is fixedly connected to one end of the top of the threaded rod.

[0011] As a further preference of this technical solution: A groove is formed in the top of the convex block.

[0012] As a further preference of this technical solution: A control switch for controlling the operating state of the cylinder is fixedly installed on the outside of the bracket.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By arranging a clamping mechanism on the base in the present utility model, after the cylinder is started, the first rack and the second rack can be driven to move downward through the gear, so that after one fixed block is pressed against the higher side of the trapezoidal sheet metal part, the other fixed block can be pressed against the lower side of the trapezoidal sheet metal part under the adjustment of the gear, and thus the two fixed blocks can respectively clamp the two different-height top surfaces of the trapezoidal sheet metal part;

[0015] 2. By arranging the first rack and the second rack meshed on both sides of the gear in the present utility model, the two fixed blocks can be adaptively adjusted when pressing the trapezoidal sheet metal part, thereby effectively improving the stability of the trapezoidal sheet metal part after being clamped by the fixture.

[0025] Among them, the clamping mechanism 2 includes a bracket 20 fixedly connected to the top of the base 1. A cylinder 29 is fixedly installed at the top of the bracket 20. The piston rod of the cylinder 29 penetrates through the bracket 20 and is rotatably connected to a gear 21. A first rack 22 is meshed and connected to one side of the gear 21, and a second rack 23 is meshed and connected to the other side of the gear 21. Movable blocks 24 are fixedly connected to the opposite sides of the second rack 23 and the first rack 22. Connecting rods 25 are uniformly and slidably connected inside the movable blocks 24.
