Description

Technical Field

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

[0002] Metal processing is a common metal processing method that processes metal parts into different shapes and structures for people's use. During the processing of metal parts, the metal parts need to be stabilized. The clamping device of the metal parts is an effective device for stabilizing the metal parts.

[0003] As shown in the announcement number CN 206883248 U, a clamping structure for metal processing is disclosed, which includes a device body; the device body is mainly composed of a base, side plates, a fixed frame, a first clamping plate and a second clamping plate, and the two ends of the base are fixedly connected to the side plates and the fixed frame respectively; and a control device is fixedly connected to the fixed frame, and a hydraulic cylinder is fixedly connected to the right side wall of the fixed frame. The device does not have a convenient stretching and contracting mechanism, and the position of the clamping mechanism cannot be adjusted according to different metal sizes, so that it cannot find the best support point, which is not conducive to clamping and fixing. At the same time, there is no automated push rod clamping mechanism, which cannot effectively clamp metals of different sizes, which may cause them to fall off during processing. No intelligent control method is adopted, which makes it more time-consuming and labor-intensive for workers to operate. Utility Model Content

[0004] The purpose of the present utility model is to provide a clamping structure for metal processing to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

The fitting grooves are movably connected to the limit blocks. The tight connection between the fitting grooves inside the hollow column and the limit blocks allows the telescopic column to move freely inside the hollow column, making it easier for the clamping mechanism to find the optimal clamping point, and significantly improving stability.

[0012] Preferably, a connecting plate is fixedly provided on the side of the hollow column away from the telescopic column, and a number of fixing screws are movably provided on both sides of the outside of the connecting plate. The connecting plate is connected and fixed with other structures by fixing screws. The simple connection method allows the device to be easily installed inside any large machine.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This is a clamping structure for metal processing.

Similarly, the main control rod is retracted to the other side, and the fine-tuning rod cooperates with the connecting rod to clamp the clamping block on one side inward to clamp and fix the metal. The position of the telescopic column can be adjusted manually, and the telescopic spring on the attachment block on one side of the telescopic column undergoes elastic deformation to drive the limit block to flexibly connect with the fitting groove inside the hollow column to complete the position change.

[0015] 2. This is a clamping structure used for metal processing. The device has a convenient stretching and contracting mechanism, which can adjust the position of the clamping mechanism according to the size of different metals, so that it can find the best support point, which is conducive to clamping and fixing. At the same time, the automated push-rod clamping mechanism can effectively clamp metals of different sizes to prevent them from falling off during the processing process. The intelligent control method makes it more time-saving and labor-saving for workers to operate. BRIEF DESCRIPTION OF THE DRAWINGS
