Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, in particular to a clamp for hardware processing. Background Art

[0002] Hardware processing involves cutting, grinding, welding, stamping, casting, and forging metal materials to achieve predetermined shapes and sizes, thereby producing hardware products with specific functions. Hardware processing is widely used in various industries, including machinery, electronics, automobiles, construction, and furniture. During hardware processing, fixtures are required to secure the workpiece.

[0003] For example, a hardware processing fixture disclosed in authorization publication number CN218313081U includes a limit frame, a movable base, and a fixture table. The movable base is slidably mounted on the top of the fixture table, a fixed rod extending from the fixture table is fixedly mounted on the bottom of the movable base, and the limit frame is bolted to the top of the movable base. By adopting the above technical solution, the beneficial effect of this utility model is that it can quickly drive the clamping base to clamp the workpiece, which is convenient and quick.

[0004] Although the above patent can drive the clamping seat to clamp the workpiece relatively quickly, there is no positioning slot on the arc seat, and it is only fixed by the end of the bolt abutting against the arc seat, which may cause the fixed seat to move. Utility Model Content

[0005] The purpose of the present utility model is to provide a hardware processing fixture to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This hardware processing clamp is used in conjunction with a positioning frame, a positioning slot, a push rod and a positioning block. When the push rod on the right is pushed, the rack moves forward until the two clamps clamp the hardware. Then, the push rod on the right is rotated, and the push rod drives the positioning block on the outer wall of the middle part to flip downward and be clamped in the positioning slot at the corresponding position on the positioning frame. In this way, after locking, the rack will not be displaced, thereby making it more stable after clamping.

[0017] 2. This hardware processing fixture is used in conjunction with rack 1, gear 2, gear 1 and rack 2. When fixing hardware, the hardware is placed on the clamping table, and then the push rod is pushed. The push rod drives rack 1 to drive gear 1 to rotate. When gear 1 rotates, it drives gear 2 to rotate synchronously through the transmission shaft. When gear 2 rotates, it controls the racks 2 on both sides to move in the same direction. When rack 2 moves, it drives the movable block through the connecting piece. When the movable block moves, it drives the splint to clamp the hardware, so that the clamping speed is faster during operation. BRIEF DESCRIPTION OF THE DRAWINGS
