Description

Technical Field

[0001] The utility model relates to the technical field of support frame processing equipment, in particular to a fixing tool for processing a metal support frame. Background Art

[0002] Metal support bracket is a rod-type bracket made of metal material, and metal is a substance with gloss, ductility, easy electrical and thermal conductivity. Metals are widely present in nature and are widely used in life. They are very important and most widely used substances in modern industry. In the metal parts processing industry, it is often necessary to drill holes in metal parts.

[0003] However, some current metal drilling devices require workers to hold the metal parts for drilling. When the workers hold the metal parts for drilling, it is inevitable that there will be shaking, inaccurate positioning or deviation in the moving distance of the metal parts. In addition, the metal drilling devices have no corresponding references, which may lead to deviations in the drilling position of the metal parts, causing the drilling process of the metal parts to fail and reduce the quality of the metal parts processing.

[0004] For example, a metal drilling tool disclosed in Chinese patent publication number CN214393294U guides the metal part between the two limit plates through a slide fixedly connected to one side of the two limit plates, quickly placing the metal part in a processing position, and energizing the electromagnet and the electromagnet plate can fix the two limit plates in position, while de-energizing the electromagnet and the electromagnet plate can push the two limit plates by the metal part, thereby achieving the purpose of automatically adjusting the distance between the two limit plates according to the size of the metal part, which is beneficial to improving the stability of the moving trajectory of the metal part, ensuring the stable and accurate movement of the metal part, improving the accuracy of the metal part drilling processing, improving the quality of the metal part processing, and reducing the economic losses caused by the failure of metal part processing.

[0005] The existing technology has the following problems:

[0006] The tooling uses an electromagnet to ensure the stability of the moving trajectory and a limit plate to limit and fix the metal parts. However, the movement of the limit plates at both ends of the device requires the push rod to move in an instantaneous direction. Once the two sets of push rods move forward and backward at different times, the limit position will be different from the expected position, which will easily lead to deviations in the limit fixing position in actual operation, and the movement of the push rod is difficult to control.
