Description

Technical Field

[0001] The utility model relates to the field of racket processing, in particular to a drilling mechanism for a badminton racket. Background Art

[0002] Now, with the improvement of people's living standards and the rise of the national fitness craze, badminton has been widely popularized. As a national sport that promotes people's health, badminton has also been loved by people, and the production volume of badminton rackets has increased accordingly. Badminton rackets are generally composed of a racket head, a racket shaft, a racket handle, and a joint between the racket frame and the racket shaft. The mesh wire on the racket head of a badminton racket is an important factor in determining the quality of the badminton racket, so the through hole for pulling the mesh wire is particularly important, especially the accuracy of the through hole position. Most of the current badminton rackets are punched manually, which is very time-consuming.

[0003] According to the public patent 202022543812.4, a drilling device for processing badminton rackets includes a base and a drilling assembly; a side panel is provided on the upper surface of the base; an arc-shaped support block is fixed to one side of the side panel; a pair of sliders are movably fitted above the arc-shaped support block; a cross plate is clamped between the pair of sliders; a pair of limit assemblies are fixed below the arc-shaped support block; an electric lifting rod is fixed to the other side of the side panel; a connecting plate is fixed to the telescopic end of the electric lifting rod; a drilling assembly is provided at the end of the connecting plate; a pair of through grooves are opened above the arc-shaped support block; a spring A is fixedly connected to the top of the inner wall of the through groove. The utility model solves the problem that the existing badminton racket is easy to loosen when drilling, thereby causing the drilling hole to be offset and affecting the quality of the badminton racket through the functions of the base, the drilling component, the arc-shaped support block, the slider, the limit component and the cross plate. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved: although the limit rod is fixedly connected to the adjacent side surfaces of the slider, when drilling the badminton racket, the cross plate is first pushed upward to push the slider upward, and then the upper end of the badminton racket is clamped in the arc-shaped clamping groove, the slider is lowered, and a pair of limit rods are used to press and fix the badminton racket to prevent it from loosening during drilling. The dynamic deviation solves the problem that most of the current badminton rackets are drilled manually, which is very time-consuming. There is also a problem of difficulty in determining the hole position when drilling holes, which leads to the badminton racket being easily loose when drilling holes, thereby causing the drilling holes to be offset, affecting the quality of the badminton racket. However, during use, the drilling mechanism of the traditional badminton racket often has some debris and slag in the hole after drilling holes in the badminton racket, which affects the perforation of the network cable. Moreover, after the badminton racket is drilled, burrs appear in the hole. When the network cable passes through the hole with burrs, it is easy to damage the network cable, affecting the service life of the network cable. For this reason, a new technical solution needs to be designed to solve the problem. Utility Model Content
