Description

Technical Field

[0001] This utility model relates to the field of billiard cue manufacturing, and in particular to a precision grinding device for billiard cue manufacturing. Background Technology

[0002] A billiard cue is a tool used to strike billiard balls and is widely used in various billiard competitions. A billiard cue usually consists of two parts: the shaft and the head. Depending on the type of billiard game and individual needs, cues come in a variety of designs and materials. Traditionally, billiard cue shafts are mostly made of wood, with maple, walnut, mahogany, and other high-density woods being the most common. Modern cue shafts also use lightweight and durable materials such as synthetic materials and carbon fiber.

[0003] In the manufacturing process of billiard cues, the polishing process has a decisive impact on the final feel, balance, and appearance quality of the cue. Traditional polishing methods mostly rely on manual operation of grinding wheels or handheld belt sanders. Manual polishing makes it difficult to guarantee the straightness, taper consistency, and surface smoothness of the cue, which can easily lead to a shift in the cue's center of gravity or a decrease in grip comfort. To address these issues, we propose a precision polishing device for billiard cue manufacturing. Utility Model Content

[0004] The purpose of this invention is to provide a precision grinding device for manufacturing billiard cues, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A precision grinding device for billiard cue manufacturing includes a housing. A casing is mounted on one side of the housing.

Combined with the rotation driven by a first motor, it ensures that the cue rotates at a uniform speed during the grinding process, avoiding problems such as eccentricity or uneven taper caused by manual operation. The arc-shaped grinding plate, with spring self-adjustment, keeps the sandpaper in contact with the cue surface, ensuring uniform grinding, improving straightness and surface finish. The movement of the grinding frame is controlled by an adjustment mechanism, which, combined with the second motor driving the second lead screw, realizes automatic adjustment of the grinding position, reducing manual intervention and improving processing efficiency. The clamping mechanism can quickly adjust the position of the second clamping sleeve to adapt to billiard cues of different lengths, improving the versatility of the equipment.
