Description

Technical Field

[0001] This invention belongs to the field of metal brake drum technology, specifically relating to a metal brake drum spraying fixture that can be quickly positioned. Background Technology

[0002] Metal brake drums are the core component of drum braking systems. They generate braking torque through friction with brake pads, enabling vehicles to decelerate or stop. Metal brake drum painting fixtures are specialized equipment for painting the surface of brake drums. They use mechanical structures to stably clamp and rotate the brake drum, working with painting components to achieve uniform coating coverage while preventing paint from adhering to non-painted areas. For example, a Chinese patent discloses a brake drum painting fixture (authorization announcement number CN221086046U). This patented technology drives a second cylinder to move a first mounting seat within a mounting groove, causing one end of the connecting arm to rotate. This, in turn, causes the abutment rods to disperse and separate, allowing the abutment joint to abut and fix against the inner wall of the annular brake drum. A drive motor then rotates the worm gear, worm wheel, and connecting rod, causing the rotating seat to rotate, thus rotating the brake drum. Finally, a spray gun is used to paint its surface, avoiding the need for transporting and repositioning the brake drum during multi-station painting processes. However, existing publicly available metal brake drum spraying fixtures still have some shortcomings in practical applications that need improvement, such as: 1. Positioning the metal brake drum using a ball requires the lower side of the metal brake drum to be in contact with the operating table during positioning, which affects the painting operation of the metal brake drum and results in poor positioning stability. 2. When the metal brake drum is placed, its lower side adheres to the table surface, making it easy to pinch hands during handling, which compromises safety and ease of use, and also hinders the positioning speed of the metal brake drum. Therefore, those skilled in the art have provided a metal brake drum spraying fixture that enables rapid positioning to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide a metal brake drum spraying fixture that can be quickly positioned, thereby solving the problems mentioned in the background art.

The spraying component is located at one upper end of the operating table, and the positioning component is located at the other upper end of the operating table. A bearing is installed at the lower end of the positioning component. An electric telescopic rod is installed on the lower side of the operating table near the positioning component. A guide slide component is provided at the upper end of the electric telescopic rod. The metal brake drum body is provided on the upper side of the guide slide component.

[0005] The present invention is further configured such that: the guide sliding component includes a support ring, a rotating seat is provided on the upper side of the support ring, and a rotating ball is provided inside the rotating seat.

[0006] The present invention is further configured such that: the transmission wheel rotates at the upper position of the operating table via a transmission motor, the outer side of the transmission wheel rotates at the outer position of the positioning member, and the positioning member rotates at the upper position of the operating table via a bearing.

[0007] The present invention is further configured such that: the guide slide member slides on the upper side of the operating table via an electric telescopic rod, and the metal brake drum body is located on the outer side of the positioning member.

[0008] The present invention is further configured such that: the first guide rod slides at the upper end of the support base, the slider slides at the outer side of the conical block, the lead screw body slides at the lower side of the support base via a through-type lead screw motor, the lower end of the second guide rod slides at the lower side of the support base, and the upper end of the second guide rod is fixed at the lower side of the conical block.

[0009] The present invention is further configured such that the rotating ball rotates at an internal position of the rotating seat, and the rotating ball rolls at a position below the metal brake drum body.

[0010] The technical effects achieved by this utility model are as follows: This utility model discloses a metal brake drum spraying fixture that can be quickly positioned. It improves the completeness of spraying by supporting the metal brake drum body through the guide sliding component, improves the stability of the metal brake drum body during rotational spraying by guiding the metal brake drum body through the guide sliding component, and improves the firmness of positioning by positioning the metal brake drum body through the positioning component.

[0011] This utility model discloses a metal brake drum spraying fixture that can be quickly positioned. The electric telescopic rod drives the guide slide component to slide on the outside of the positioning component, automatically adjusting the height of the metal brake drum body. This prevents the lower side of the metal brake drum body from touching the operating table, improving the safety of the metal brake drum body placement and operation, increasing the convenience of picking and placing, and facilitating the positioning speed of the metal brake drum body.
