Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a milling positioning tooling for a dynamic plate of a scroll compressor. Background Art

[0002] like Figure 7 The figure shows a scroll compressor moving plate. In order to ensure the sealing and assembly accuracy, its upper surface and scroll side wall need to be milled. Since the entire upper surface needs to be processed, it is difficult to position. At present, the upper surface is usually pressed down by a cylinder to position it. After other parts are processed, the pressed parts are replaced for secondary processing. Secondary processing reduces processing efficiency and requires repositioning, which will also bring new errors. At the same time, the processed parts are pressed, which is easy to produce indentations and affect product quality. Utility Model Content

[0003] In order to solve the above problems existing in the prior art, the utility model provides a milling positioning tool for a scroll compressor moving plate which is easy to use, has stable positioning, and can improve processing accuracy and processing efficiency.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A milling and positioning tool for a scroll compressor moving plate comprises a base, a support seat is fixedly provided on the base, a flow plate is provided on the support seat, and the flow plate and the support seat are supported and detachably connected; a first positioning pin for positioning the compressor moving plate is provided on the flow plate, and a plurality of first bolts are provided on the flow plate and connected to the threaded holes at the bottom of the compressor moving plate through the flow plate.

[0006] The base is installed on the workbench of the milling machine. When in use, first take down the flow plate, connect the compressor moving plate with the flow plate, then connect the flow plate with the support seat, and then mill the surface of the compressor moving plate. The clamping is very convenient, and all processing can be completed in one clamping, eliminating the secondary clamping operation, and effectively improving the processing efficiency and processing accuracy.

[0007] Preferably, the support seat is provided with a second positioning pin for positioning the flow plate, and the flow plate is provided with a second positioning hole adapted to the second positioning pin; the base is provided with a plurality of clamping assemblies for clamping and positioning the flow plate on the support seat. After the compressor moving plate is connected to the flow plate, the flow plate is positioned with the support seat through the second positioning pin and then clamped and positioned by the clamping assembly.

[0008] Preferably, the clamping assembly includes a cylinder with its shaft end facing upward, a pressure block rotatably connected to the cylinder shaft, a rotating seat fixedly provided on the cylinder housing, and the middle part of the pressure block rotatably connected to the rotating seat via a connecting arm; when the cylinder shaft is extended, the end of the pressure block presses the flow plate, and when the cylinder shaft is retracted, the pressure block is separated from the flow plate.

[0009] Preferably, the first positioning pins are configured as two, one of which is a cylindrical pin and the other is a diamond pin. The use of two different forms of positioning pins can increase the convenience of positioning between the compressor moving plate and the flow plate while meeting the positioning accuracy.

[0010] Preferably, at least three sets of adapters are provided at the edge of the top surface of the flow plate, and the adapters are threadedly connected to the flow plate. When the flow plate and the support seat are positioned by the second positioning pin, the clamping assembly is pressed on the top surface of the adapter. Repeated long-term pressing of the clamping assembly on the same part of the flow plate will cause pits on the surface of the flow plate. After the adapter is used, the clamping assembly is pressed on the adapter. After the pit is generated on the adapter, the adapter is directly replaced.

[0011] Preferably, at least three upwardly protruding support parts are provided at the top edge of the support seat, the top surfaces of all the support parts are coplanar, and the bottom surface of the flow plate contacts the top surfaces of the support parts. The cooperation between the support parts and the flow plate increases the processing convenience of the support seat (the three support surfaces have high positioning accuracy and convenient flatness processing), and makes it easier to observe whether there are debris residues on the support parts before installing the flow plate.

[0012] Preferably, three groups of supporting feet are provided at the bottom edge of the supporting seat, and the bottom surfaces of the supporting feet are coplanar. By connecting the supporting feet with the base, the flatness processing of the supporting feet is more convenient.

[0013] Preferably, the base plate is provided with third locating pins, two third locating pins are configured, the two third locating pins are positioned with any two groups of supporting feet, and the base plate and the supporting feet are connected by second bolts.

[0014] Preferably, the bottom plate is provided with a first reference hole, the support seat is provided with a second reference hole coaxially distributed with the first reference hole, and the flow plate is provided with a third reference hole coaxially distributed with the first reference hole. The first reference hole, the second reference hole, and the third reference hole are coaxially distributed, which facilitates the positioning of the milling machine spindle box.

[0015] Therefore, the utility model has the beneficial effects of being easy to use, stable in positioning, and capable of improving processing accuracy and processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
