Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a ring-shaped wire jig with a self-locking function. Background Technology

[0002] With the rapid development of automotive technology, the demand for compressors, as the core component of automotive air conditioning systems, is increasing year by year. The compressor coil, as the most crucial component of the compressor, determines the overall quality of the air conditioning system, making quality control of the compressor coil essential. Therefore, automotive component manufacturers currently primarily use automated methods for coil assembly. However, the compressor coil assembly process requires a self-locking fixture. This fixture must meet three conditions: First, when assembling the coil components in the compressor coil, the floating block assembly in the fixture must be in its initial raised state for positioning the inner diameter of the coil components. Second, when assembling the outer casing components in the compressor coil, the outer casing will interfere with the floating block assembly in the fixture, pressing the floating block down and self-locking it. Third, when the fixture reaches the last station on its circular movement line, the locking mechanism needs to be opened, and the floating block assembly needs to be raised and returned to its initial state. The stability and reliability of this fixture are crucial to the entire assembly process.

[0003] Currently, there is a lack of jigs on the market that meet the above three conditions. Therefore, it is necessary to design a ring-shaped jig with a self-locking function to meet the assembly requirements. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the present invention aims to provide a ring-shaped jig with a self-locking function, thereby solving the problem of the lack of a jig that can simultaneously meet the requirements of initial positioning, self-locking, and reset in the existing compressor coil assembly process.

[0006] The floating block assembly, installed on the main body, is used to position the inner hole of the coil product and achieves self-locking through the linkage between the self-locking connecting block and the connecting plate;

[0007] A reset spring and a spring post, wherein the spring post is fixed on the base plate, and the reset spring is sleeved on the spring post and connected to the floating block assembly for driving the floating block assembly to reset;

[0008] Anti-rotation pin, fixed to the base plate and cooperating with the floating block assembly, prevents the floating block assembly from rotating when it moves up and down;

[0009] Reset pin and spring, wherein the reset pin is fixed on the connecting plate, and the spring is arranged on the reset pin and connected with the self-locking connecting block, so as to provide the reset force of the self-locking connecting block.

[0010] Further, the main body is fixed with a positioning block, and the floating block assembly is movably installed in the middle of the positioning block.

[0011] Further, the main body is fixed with a product supporting block on the side surface, so as to angularly position the coil product.

[0012] Further, the floating block assembly comprises a floating block, a floating block connecting plate fixed on the bottom of the floating block, a self-locking pin fixed on the side surface of the floating block connecting plate, and a positioning copper sleeve press-fitted into the floating block.

[0013] Further, the coil product comprises a coil component and a shell component assembled in the coil component.

[0014] Further, the bottom plate is fixed with a flat key at the bottom, so as to position the jig on the annular wire.

[0015] Further, the main body is fixed with a positioning pin, so as to position the annular wire in the riveting process.

[0016] Further, the reset force of the reset spring is perpendicular to the compression direction of the spring, and the self-locking connecting block is self-locked and unlocked by the compression and release of the spring.
