Technical Field
[0001] The utility model relates to the technical field of punching fixtures, in particular to a special fixture for non-four-axis punching of a scroll stator. Background Art
[0002] The scroll machine is a positive displacement fluid machine, which is mainly composed of key components such as the movable scroll, the fixed scroll, the anti-rotation mechanism, the crankshaft, and the sealing mechanism. This machine has few moving parts and is characterized by low noise, low vibration, high efficiency, and high reliability. However, the scroll profile design not only determines the difficulty of processing, but also directly affects the performance of the machine. Therefore, a special punching fixture needs to be designed when processing the scroll.
[0003] The traditional four-axis punching method has problems such as numerous processes and poor precision in multiple clamping, which leads to low production efficiency. The non-four-axis punching special fixture can clamp quickly, realize efficient synchronous processing, and greatly improve production efficiency. Utility Model Content
[0004] The utility model aims to provide a special fixture for non-four-axis drilling of a scroll stator, so as to solve the defects of the existing four-axis drilling method, such as complicated working procedures, poor precision of multiple clamping, etc., which leads to low production efficiency.
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a special fixture for non-four-axis punching of a scroll stator, comprising a support frame;
[0006] The top of the support frame is evenly fixed with a limiting structure, and a fixing seat is evenly fixed on the side of the top of the support frame away from the limiting structure;
[0007] A holding structure is evenly fixed on one side of the top of the support frame, and the holding structure includes a holding block, a cylinder and a mounting frame. The mounting frame is evenly fixed on one side of the top of the support frame, and a cylinder is arranged on the top of the mounting frame, and a cylinder is arranged on one side of the mounting frame;
[0008] A base is arranged on one side of the top of the support frame close to the mounting frame, a positioning structure is arranged at the bottom of the base, limited seats are evenly fixed on both sides of the top of the support frame, and reserved holes are evenly opened on both sides inside the support frame.
[0009] Furthermore, the limiting structure includes an electric telescopic rod, a fixing frame, a limiting frame, a connecting rod and a limiting block. The fixing frame is evenly fixed to the top of the supporting frame, and the electric telescopic rod is installed on one side of the fixing frame.
[0010] Furthermore, a limiting frame is provided on one side of the fixing frame, one end of the electric telescopic rod extends to the outside of the fixing frame and is fixed with a connecting rod, and one end of the connecting rod passes through the limiting frame and is fixed with a limiting block.
[0011] Furthermore, one side of the limit block and the outer side of the scroll stator are in conflict with each other, and two groups of the limit blocks are provided.
[0012] Furthermore, the holding block is hingedly connected to the cylinder, and the holding block is hingedly connected to the mounting frame.
[0013] Furthermore, the positioning structure includes a positioning groove, a positioning block and a guide groove. The positioning groove is opened at the bottom of the base.

[0015] The utility model provides a special fixture for non-four-axis drilling of the scroll stator, which has the following advantages:
[0016] By providing a holding structure and starting the cylinder, the lifting and lowering of the top end of the cylinder can drive one end of the holding block to move up and down. When one end of the holding block moves up and down, its middle position will rotate around the top end of the mounting frame. When one end of the holding block rises together with the top end of the cylinder, the other end of the holding block drops. At this time, the end of the holding block close to the scroll and stator disk will be pressed on the top end of the scroll and stator disk to press down and fix the scroll and stator disk. Therefore, when punching holes in the scroll and stator disk, it is only necessary to place the scroll and stator disk in the specified position, and then start the cylinder to quickly press down and clamp the scroll and stator disk, thereby realizing the function of fast clamping of the device and improving the convenience and work efficiency of the special fixture for non-four-axis punching of the scroll and stator disk when in use.
[0017] By setting a limited position structure and starting the electric telescopic rod, the extension of the electric telescopic rod will drive the limit block to contact the side of the scroll stator through the connecting rod, so as to limit and fix the scroll stator, thereby avoiding the displacement of the scroll stator during drilling and affecting the drilling accuracy. The device has the function of facilitating the limit position of the scroll stator, and improves the stability of the special fixture for non-four-axis drilling of the scroll stator during use.
[0018] By providing a positioning structure, when installing the base, the positioning groove is sleeved on the top of the positioning block through the guide groove, so that the base can be placed in the correct position, avoiding deviation of the scroll stator when positioning, and realizing the function of facilitating the positioning of the base, thereby improving the convenience of using the special fixture for non-four-axis drilling of the scroll stator.

The limiting structure 2 includes an electric telescopic rod 21, a fixed frame 22, a limiting frame 23, a connecting rod 24 and a limiting block 25. The fixed frame 22 is evenly fixed on the top of the support frame 1. The electric telescopic rod 21 is installed on one side of the fixed frame 22. A limiting frame 23 is set on one side of the fixed frame 22. One end of the electric telescopic rod 21 extends to the outside of the fixed frame 22 and is fixed with a connecting rod 24. One end of the connecting rod 24 passes through the limiting frame 23 and is fixed with a limiting block 25. One side of the limiting block 25 and the outer side of the scroll stator are in conflict with each other. Two groups of limiting blocks 25 are provided. A fixing seat 5 is evenly fixed on the side of the top of the support frame 1 away from the limiting structure 2.
[0029] The external power supply starts the electric telescopic rod 21.
