[0015] (III) Beneficial Effects

[0016] This utility model provides a workpiece rotation positioning fixture for a powder coating production line, which has the following advantages:

[0017] 1. This powder coating production line uses a workpiece rotation positioning fixture. Through the configuration of transmission and clamping components, during use, the workpiece is placed on one side of the positioning plate according to the required clamping diameter. Then, the second output motor is started, which drives the transmission gear, which in turn drives the rotating column and turntable to rotate simultaneously. The turntable pushes the slide rod, causing the clamping block to slide in the groove on the positioning plate, thereby clamping workpieces of different diameters. At the same time, the first output motor is started, which drives the rotating sleeve to rotate, causing the clamping block to rotate the workpiece. This achieves rapid clamping of workpieces of different diameters and ensures that the powder coating achieves full-angle coverage, avoiding uneven coating thickness and improving coating efficiency.

[0018] 2. This powder coating production line uses a workpiece rotation positioning fixture. Through the setting of the rotating component, during use, depending on the length of the workpiece, in long workpiece mode, the second drive motor is started, driving the threaded rod to rotate, which in turn drives the slider to drive the base plate, and the two sets of support frames move synchronously. The clamping blocks are used to rigidly clamp both ends of the workpiece. In short workpiece grouping mode, the first drive motor is started, and after the torque is increased by the reducer, the drive shaft flips the fixed plate to vertically position it, so that a single set of fixtures splits into two independent units, which can simultaneously process two small workpieces. The dual-mode fixture can be switched to achieve the effect of flexibly dealing with workpieces of different sizes, enabling one machine to be used for multiple purposes and improving the applicability of the fixture.

[0028] Two sets of stress plates 13 are fixedly connected to the top of both sides of the base plate 8, and two sets of limiting blocks 14 are fixedly connected to the bottom of the base plate 8. The setting of the limiting blocks 14 plays a role in increasing the stability of the movement of the base plate 8.
