Description

Technical Field

[0001] This utility model relates to the field of moving scroll plate machining technology, and in particular to a moving scroll plate machining tooling. Background Technology

[0002] A scroll compressor is a positive displacement compressor. Its compression component consists of a moving scroll and a stationary scroll. The moving scroll rotates and translates around an eccentric crankshaft. Due to the tangential gas force, the moving scroll also has a rotational motion around its own base circle. This rotational motion, together with the stationary scroll, forms four crescent-shaped compression chambers between them. When machining the moving scroll, a fixture is needed to fix it.

[0003] To address this, patent CN223313551U discloses a precision machining fixture for a moving scroll plate. From bottom to top, it includes a base plate, a housing, and a positioning block. The housing cavity is equipped with a lifting mechanism, which, from top to bottom, includes an expansion sleeve for fixing parts, a diaphragm disc for driving the expansion sleeve to open, and a piston for ejecting the diaphragm disc. A vent hole is provided on one side of the housing for driving the piston to move. In use, this invention utilizes a lifting mechanism within the housing cavity. This lifting mechanism includes an expansion sleeve, a diaphragm disc, and a piston. The vent hole drives the piston to move, causing the piston to eject the diaphragm disc. Once ejected, the expansion sleeve deforms and opens, thus fixing the parts and preventing deformation when using a three-jaw chuck.

[0004] Existing machining fixtures for moving scrolls have poor positioning performance and are not convenient for clamping and fixing moving scrolls of different sizes, which affects the machining efficiency of moving scrolls. Utility Model Content

[0005] The purpose of this utility model is to provide a machining fixture for a moving scroll plate, in order to solve the defect of poor positioning effect of an existing machining fixture for a moving scroll plate.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a machining fixture for a moving scroll plate, including a base, a clamping structure on the base, a moving scroll plate body mounted on the clamping structure, the clamping structure including a fixed cylinder mounted on the base, a connecting shaft mounted on the output end of the fixed cylinder, a lifting frame mounted on the top end of the connecting shaft, clamping plates evenly hinged on the lifting frame and a rubber pad mounted on one end of the clamping plates, a lower support mounted on the base between adjacent clamping plates, an auxiliary structure inside the lower support, an upper support mounted on the lower support, and an adjustment structure between the upper support and the lower support.

[0007] Preferably, the inner side of the rubber pad is provided with anti-slip texture.

[0008] The above structure increases the friction between the clamping plate and the moving scroll plate, thus enhancing the clamping effect.

[0009] Preferably, the upper surface of the upper bracket has a groove.

[0010] The above structure can provide a certain degree of limitation for the moving scroll disk.

[0011] Preferably, the auxiliary structure includes a limiting block, a ash receiving tray, a moving block, a limiting groove, and a telescopic spring. The limiting blocks are all installed on the inner side wall of the lower support. The ash receiving tray is installed on the limiting block. The side wall of the ash receiving tray is evenly provided with limiting grooves. The inside of each limiting groove is symmetrically installed with a telescopic spring, and a moving block is installed at one end of each telescopic spring.

[0012] The above structure can collect the waste chips and dust generated during the processing of the moving scroll plate.

[0013] Preferably, one end of the movable block is disposed in the limiting groove, and the movable block and the telescopic spring form a telescopic structure.

[0014] With the above structure, the telescopic spring can move the moving block so that it contacts the clamping plate.

[0015] Preferably, the adjustment structure includes a slot and a block, the block being symmetrically installed at the bottom of the lower bracket, and the slot being evenly distributed on the upper surface of the lower bracket.

[0016] The above structure allows for adjustment of the position of the upper support to support and limit the movement of rotating disks of different sizes.

[0017] Preferably, the card block and the card slot cooperate to form an engaging structure.

[0018] The above structure allows for quick fixation of the upper bracket.

[0019] The advantages of the machining fixture for a moving scroll plate provided by this utility model are as follows: The clamping structure can clamp and fix moving scrolls of different sizes, improving processing efficiency. The adjustment structure can adjust the position of the upper support to support and limit moving scrolls of different sizes. The auxiliary structure can collect waste chips and dust generated during the processing of moving scrolls.

[0020] With the clamping structure in place, the fixed cylinder is activated, and the connecting shaft drives the lifting frame to move upward. Under the limiting action of the lower bracket, the clamping plate moves towards the moving scroll until it contacts the moving scroll, thus achieving the purpose of clamping and fixing moving scrolls of different sizes and improving processing efficiency. The upper bracket is designed to limit the movement of the scroll plate by its groove. By inserting the locking block into the slots at different positions, the position of the upper bracket can be adjusted to limit the movement of scroll plates of different sizes. With the auxiliary structure in place, when the clamping plate moves, the moving block moves into the limiting groove and contacts the clamping plate. The dust collection tray can collect the waste chips and dust generated during the processing of the moving scroll plate, preventing the waste chips and dust from falling into the clamping structure and affecting its performance.
