AI Technical Summary
In existing technologies, the unstable rotation speed of manually controlled steel wheels leads to uneven spraying, necessitating the design of a suspension device capable of automatic rotation.
A stable self-rotating spraying fixture was designed, including a fixture body and an automatic power structure. The axial movement and self-rotation of the fixture are realized through a guide unit and a self-rotation unit, and automatic rotation is achieved by using components such as sprockets and guide bearings.
It enables automatic rotation of the steel wheel during the spraying process, ensuring uniform spraying, reducing manual intervention, and improving production efficiency.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical equipment technology and relates to a stable self-rotating spraying fixture. Background Technology
[0002] On the existing painting overhead conveyor, the steel wheels entering the spray booth need to be sprayed manually. After the steel wheels enter the spray booth, the employees use their hands to rotate the steel wheels while using a spray gun to spray them. Due to the unstable speed control by manual operation, the spraying is uneven. Now, a hanging device needs to be designed to hang on the overhead conveyor. After reaching the spray booth, it will automatically start rotating and stop rotating in coordination with the mechanism below. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a spraying fixture that solves these problems.
[0004] The objective of this utility model can be achieved through the following technical solution: A stable self-rotating spraying fixture, comprising a fixture body and an automatic power structure that cooperates with the fixture body and drives the fixture body to move and rotate, characterized in that the fixture body includes a rotating shaft platform, a fixed cylinder sleeved on the rotating shaft platform and movably connected thereto, and a main hanging body connected to the fixed cylinder. The main hanging body includes a fixture frame and a hook connected to the fixture frame. A guide unit is provided on the outer peripheral wall of the fixed cylinder, which is connected to it, has a guiding function, and cooperates with the self-rotating power structure. The guide unit includes a connecting plate connected to the fixed cylinder and a guide block connected to the connecting plate. A rack with external teeth is provided on one side wall of the guide block, and several guide bearings connected to it are provided on the lower end face of the guide block on the other side. The lower end of the rotating shaft platform extends axially downward and axially extends out of the extension of the fixed cylinder. A self-rotating unit for the rotation of the rotating shaft platform is provided on the extension of the rotating shaft platform.
[0005] In the aforementioned stable self-rotating spraying fixture, the self-rotating unit includes a sprocket sleeved on and connected to the extension.
[0006] In the aforementioned stable self-rotating spraying fixture, the guide bearing and the guide block are connected via a bearing shaft.
[0007] Compared with existing technologies, this stable self-rotating spraying fixture controls the axial movement of the fixture by setting up a guide unit and a self-rotating unit, while also being able to rotate. Attached Figure Description
[0008] Figure 1 This is a schematic diagram of the three-dimensional structure of this stable self-rotating spraying fixture.
[0009] In the diagram, 1 is the rotating shaft platform; 2 is the fixed cylinder; 3 is the main body; 4 is the connecting plate; 5 is the guide block; 6 is the rack; 7 is the guide bearing; and 8 is the sprocket. Detailed Implementation
[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0011] like Figure 1 As shown, this stable self-rotating spraying fixture includes a fixture body and an automatic power structure that cooperates with the fixture body and drives the fixture body to move and rotate. The fixture body includes a rotating shaft platform 1, a fixed cylinder 2 sleeved on the rotating shaft platform 1 and movably connected to it, and a main hanging body 3 connected to the fixed cylinder 2. The rotating shaft platform 1 and the fixed cylinder 2 are movably connected by several movable bearings. The main hanging body 3 includes a fixture frame and hooks connected to the fixture frame. The fixture frame can be designed according to actual needs. The outer peripheral wall of the fixed cylinder 2 is provided with a guide unit connected to it, which has a guiding function and cooperates with the self-rotating power structure. The unit includes a connecting plate 4 connected to the fixed cylinder 2 and a guide block 5 connected to the connecting plate 4. A rack 6 with external teeth is provided on one side wall of the guide block 5 and connected thereto. Several guide bearings 7 are provided on the lower end face of the guide block 5 on the other side and connected thereto. The lower end of the rotating shaft platform 1 extends axially downward and axially passes through the extension of the fixed cylinder 2. The rotating shaft platform 1 is provided on the extension with a self-rotating unit that cooperates with the automatic force structure and is used for the self-rotation of the rotating shaft platform 1. The self-rotating unit includes a sprocket 8 sleeved on the extension and connected thereto. The guide bearings 7 and the guide block 5 are connected through a bearing shaft.
