Description

Technical Field

[0001] The utility model relates to the technical field of mechanical component processing, in particular to a punching device for mechanical component processing. Background Art

[0002] Punching refers to punching various patterns on materials such as steel plates, leather, cloth, and wood to meet different needs. In the process of machining mechanical parts, punching operations are often required.

[0003] Publication number: CN 214053334 U proposes a punching device for machining mechanical parts. In this case, a clamping block is used to limit the position of a part to be punched under the elastic force of a spring, so that the part will not be offset during machining and the plate will not be wasted. In addition, a collection box is provided, and waste materials of the punched parts fall into the collection box through the waste hole for collection, so that it is convenient for staff to clean up the waste. The device has a reasonable structure, is easy to clean, and is very convenient to install. However, when it is in operation, only one hole position can be punched at a time. When multiple punchings are required, the position of the part must be continuously adjusted. Not only is the punching efficiency low, but positioning errors are also prone to occur, resulting in the scrapping of parts. Therefore, it is necessary to propose a punching device for machining mechanical parts to solve the above problems. Utility Model Content

[0006] By adopting the above technical scheme, the mechanical parts to be processed are placed on the punching base and clamped and fixed by the clamping parts. Before punching, the first screw is first rotated to push the movable plate to slide back and forth in the rectangular frame. Under the sliding cooperation of the limit groove and the limit column, the adjustment block slides left and right on the cross bar, and the distance between multiple punching heads can be adjusted, so as to accurately adjust the punching position. When the cylinder drives the rectangular frame to press down, the processing of multiple hole positions can be completed at one time, which not only has high processing accuracy, but also greatly improves the processing efficiency.

[0010] By adopting the above technical solution, the movable plate can slide smoothly in the plane of the rectangular frame under the push of the first screw rod, and the cross bar is used to adjust the sliding limit of the block, so that the spacing adjustment is more stable.

[0011] The utility model is further configured as follows: the clamping component includes fixed plates installed at both ends of the top of the punching base, T-shaped clamping plates are provided on opposite sides of the two fixed plates, a second screw rod rotatably connected to the T-shaped clamping plate is threadedly installed on the right fixed plate, an elastic member is provided between the left fixed plate and the T-shaped clamping plate, and a limiting rod slidably connected to the bottom of the two T-shaped clamping plates is also installed in the punching base.

[0012] By adopting the above technical solution, when fixing the mechanical parts, the second screw is rotated, and under the restriction of the limit rod, the T-shaped clamping plate on the right is pushed to the left, so that the two T-shaped clamping plates are closer, and with the cooperation of the elastic member, the mechanical parts are clamped and fixed.

[0013] The utility model is further configured as follows: the elastic member comprises a U-shaped frame installed on the side of the T-shaped clamping plate and slidably connected to the fixed plate, and a plurality of springs respectively connected to the T-shaped clamping plate and the fixed plate are installed on the inner side of the U-shaped frame.

[0014] By adopting the above technical solution, when the left T-shaped clamping plate is pressed, the U-shaped frame slides leftward and compresses the spring, and the elastic force of the spring pushes the mechanical parts tightly, making the punching operation more stable.

[0015] 1. The utility model rotates the first screw to push the movable plate to slide forward and backward in the rectangular frame. Under the sliding cooperation of the limit notch and the limit column, the adjustment block slides left and right on the cross bar, and the distance between multiple punching heads can be adjusted, so as to accurately adjust the punching position. When the cylinder drives the rectangular frame to press down, the processing of multiple hole positions can be completed at one time, which not only has high processing accuracy, but also greatly improves the processing efficiency.

[0016] 2. In the utility model, the second screw is rotated, and under the restriction of the limit rod, the T-shaped clamping plate on the right is pushed to move left, so that the two T-shaped clamping plates are close to each other, and the mechanical parts are clamped and fixed. When the left T-shaped clamping plate is under pressure, the U-shaped frame slides to the left and compresses the spring. The elastic force of the spring pushes the mechanical parts tightly, making the punching operation more stable. BRIEF DESCRIPTION OF THE DRAWINGS
