Description

Technical Field

[0001] The utility model belongs to the technical field of workpiece punching, in particular to a positioning mechanism for workpiece punching. Background Art

[0002] The positioning mechanism for workpiece punching is a device used to determine the position of the workpiece and keep it fixed during the workpiece punching process. It usually consists of multiple components, including a fixed base, positioning fixtures, adjustment devices and sensors. These components work together to ensure that the workpiece is in the correct position during punching.

[0003] When a workpiece needs to be punched, it is first placed on the positioning fixture of the positioning mechanism. Then, the position and angle of the positioning fixture are adjusted by the adjustment device to place the workpiece in the correct punching position. Next, the sensor detects the position and state of the workpiece to ensure accurate positioning. Finally, the punching equipment performs the punching operation on the workpiece.

[0004] However, during the welding process, the welding area will be subjected to high heat input, and the temperature will rise sharply, while the temperature of the part far away from the welding area is relatively low. This uneven heating causes a temperature gradient inside the workpiece. Since the workpiece is welded first and then punched, the deformation after welding makes it difficult to automatically adjust the position of the workpiece. It is not easy to ensure that the punch is aligned with the workpiece, making it difficult to reduce errors. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides a positioning mechanism for workpiece punching, which solves the problem that the workpiece is inevitably deformed after welding.

[0007] The floating mechanism includes a cross spring, a guide rail, a guide rail mounting plate and a floating base. The guide rail is installed on one side of the guide rail mounting plate. There are two cross springs, which are respectively installed at both ends of the guide rail mounting plate. The surface of the guide rail is slidably connected with a limiting block, and the floating base is installed on one side of the limiting block.

[0008] Preferably, the bottom of the mounting plate is fixedly connected to the base plate via a fixing bolt, both ends of the base plate are fixedly connected to fixing bars, and the surface of the fixing bar is fixedly installed with a limit bolt.

[0010] Preferably, the top surface of the slider is fixedly installed with a top plate by a first bolt, the top surface of the top plate is fixedly connected to a fixing seat, one side of the fixing seat is fixedly connected to a connecting rod by a fixing block, one end of the connecting rod is slidably connected to a fixing frame, one side of the fixing frame is fixedly installed with a first cylinder by a fixing plate, and the bottom surface of the fixing frame is connected to the top surface of the mounting plate.

[0011] Preferably, the other side of the guide rail mounting plate is connected to the other side of the fixing seat, and a concave template is fixedly mounted on one side of the floating base.

[0012] Preferably, the punching mechanism includes a second cylinder, a stabilizing disk and a punch, the punch is fixedly mounted on the output end of the second cylinder through the stabilizing disk, a fixing box is fixedly mounted on the surface of the second cylinder, and one end of the fixing box is connected to one end of the cross spring.
