Description

Technical Field

[0001] This invention relates to the field of compressor technology, specifically to a high-precision scroll plate machining method. Background Technology

[0002] Scroll compressors are positive displacement compressors that are energy efficient, quiet, stable in operation, and relatively simple in structure. They are widely used in automotive air conditioning and air compressor fields.

[0003] The most critical components of a scroll compressor are the precision and surface finish of the scroll moving and stationary discs. Currently, no processing equipment on the market can effectively solve these problems.

[0004] Existing machine tool processing methods involve keeping the scroll plate part stationary while the tool moves along a trajectory during machining. However, this cutting method produces tool marks. Although horizontal milling and turning machines can improve tool marks by having the scroll plate part and the tool move along the same trajectory, the parallelism, concentricity, perpendicularity, and surface finish requirements of the two surfaces of the scroll plate part are extremely high, which existing processing equipment and processes cannot meet. Moreover, common scroll plate machining methods employ sequential machining, and secondary clamping makes it difficult to guarantee the required accuracy and surface finish of the parallelism, concentricity, perpendicularity, and surface finish of the two surfaces.

The clamping rotation control lever 658, under the control of its motor, can extend and retract vertically, driving the rotation of the clamping rotation gear 657. The rotation of the clamping rotation gear 657 allows the entire U-shaped substrate 652 assembly (including the U-shaped substrate 652, chuck 653, chuck base 654, and stepper motor 655) to rotate along the hinge pin 656.

[0052] The scroll plate machining device 5 includes a scroll plate machining base 51 and a scroll plate machining electric spindle 52. The scroll plate machining base 51 is controlled by a transverse magnetic linear motor and a longitudinal magnetic linear motor to perform two-axis trajectory movements in the X and Z directions on the machining table 1 on the other side of the rotary clamping device 3. The scroll plate machining electric spindle 52 is mounted on the inner end face of the scroll plate machining base 51.

The scroll plate machining tool magazine device 54 includes a scroll plate tool magazine bracket 1 541, a tool magazine support 542, a scroll plate tool magazine bracket 2 543, and several scroll plate tool holders 544.

[0053] The moving plate machining tool magazine device holds several moving plate machining tools 43, and the stationary plate machining tool magazine device 54 holds several stationary plate machining tools 53, which can be easily changed at any time during the scroll plate machining process. Moreover, the several moving plate tool holders 441 and stationary plate tool holders 544 are all C-shaped clamps, which makes it easy for the tools to be locked in the tool holder from the side.

[0054] The rotary clamping device 3 includes a clamping base 31 and at least two rotary clamping station holes 32 disposed on the clamping base 31. The rotary clamping station holes 32 penetrate through the front and rear end faces of the clamping base 31. Multiple synchronous peripheral jaws are disposed in the rotary clamping station holes 32. The synchronous peripheral jaws move synchronously to the center under the control of a motor and squeeze and clamp the outer periphery of the raw material vortex disk. The multiple synchronous peripheral jaws can rotate as a whole under the control of a motor.

[0055] At least two rotary clamping station holes 32 are provided, so that the scroll moving plate processing device 4 can perform scroll moving plate surface processing on the raw material scroll plate in one of the rotary clamping station holes 32, while the scroll stationary plate processing device 5 can simultaneously perform scroll stationary plate surface processing on the raw material scroll plate in the other rotary clamping station holes 32; after the processing of each surface is completed, the position is reversed to process the raw material scroll plate in the other rotary clamping station hole 32, which greatly improves the processing efficiency of the scroll plate.

[0056] The working principle of the scroll disk machining system of the present invention is as follows:

[0057] 1. In the central control system of the scroll plate machining system of this device, the standard position of the scroll plate machining of the raw material to be processed in the rotating clamping device 3, as well as the tool machining motion macro program in the scroll plate machining device 4 and the scroll plate machining device 5 on both sides are pre-set.

[0058] II. In the central control system of the scroll machining system of this device, the standard position of the raw material scroll on the blank material tray 7 located on one side of the machining table 1 is preset. Assuming that the standard position of the raw material scroll on the blank material tray 7 is position one, and the standard position of the scroll machining of the rotary clamping device 3 is position two, the motion trajectory macro program of this raw material scroll from position one to position two through the gantry imaging system is also preset.

[0059] Third, the camera 642 captures a photograph of the actual position of the raw material scroll plate on the blank material tray 7 located on one side of the processing table 1, including its placement angle, and compares it with the standard position one of the raw material scroll plate; then, by adjusting the X, Y, and Z axis motion displacements of the transverse slide rail device 66, the longitudinal slide rail device 61, and the vertical lead screw device 631 in the gantry imaging system 6, as well as the rotation angle in the clamping device 65, the raw material scroll plate is clamped; finally, after clamping the raw material scroll plate, it returns to the initial standard position one of the raw material scroll plate, and then sends the raw material scroll plate to the rotary clamping device 3 (i.e., the standard position two of the scroll plate processing in the rotary clamping device 3) according to the set macro program.

[0060] IV. The Scroll Moving Disk Machining Device 4 and the Scroll Stationary Disk Machining Device 5, under the coordination of the rotational motion of the rotary clamping device 3, have their machining tools performing cutting operations on the moving disk surface and the stationary disk surface of the scroll disk respectively according to the preset motion macro program.

[0061] 5. After the raw material scroll plate and the moving and stationary plates are processed one after the other, the finished scroll plate is taken out from the rotating clamping device 3 by the clamping device 3 and placed on the finished material plate 8 located on the other side of the processing table 1, thus realizing the entire processing process of the high-precision scroll plate.

[0062] This invention provides a high-precision scroll plate machining method. The method uses a rotary clamping device 3 to clamp the outer periphery of the raw material scroll plate, and tools on both sides to machine the moving and stationary plate surfaces. This reduces the adverse effects of multiple clamping operations in sequential machining on the parallelism, concentricity, perpendicularity, and surface finish of the moving and stationary plate surfaces. The gantry imaging system 6 effectively achieves the placement and positioning of the raw material scroll plate, realizing the automation, high precision, and high standardization requirements of scroll plate machining. The moving plate machining electric spindle 42 on one side of the rotary clamping device 3 moves along the X, Y, and Z axes, and in conjunction with the rotation of the rotary clamping device 3, enables 3D contour cutting. The stationary plate machining electric spindle 52 on the other side of the rotary clamping device 3 moves along the X and Z axes, and in conjunction with the rotation of the rotary clamping device 3, and through a system macro program, enables continuous turning and grinding cutting. This effectively ensures the parallelism, concentricity, and surface finish requirements of the two surfaces of the scroll plate.

[0063] This invention provides a high-precision scroll plate machining method with high machining efficiency. It can effectively meet the requirements of automation, high precision, and high standardization in scroll plate machining, and ensure product consistency and pass rate, while greatly improving production efficiency and saving labor costs.

[0064] The invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the invention, or the direct application of the inventive concept and technical solution to other situations without modification, is within the protection scope of the invention.
