[0027] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] See Figure 1 , which shows a schematic structural diagram of a compressor packing disassembly and assembly tooling in an embodiment of the present utility model. This embodiment is applied to a Burkhardt compressor, which includes a connecting rod 100, a pressure plate 200 and a tray 300. The pressure plate 200 and the tray 300 are detachably connected to the connecting rod 100. When disassembling and reinstalling, the pressure plate 200 and the tray 300 are selectively installed on the connecting rod 100.

[0029] See Figure 2 and Figure 3 , the central position of the pressure plate 200 is threadedly connected to the connecting rod. Specifically, an M12 internal thread hole is opened at the central position of the pressure plate 200, and the internal thread hole is connected to the external thread of the connecting rod 100. The pressure plate 200 includes a first disc part 210 and a cylindrical part 220 concentrically arranged with the first disc part 210. In this embodiment, the first disc part 210 and the cylindrical part 220 are integrally formed.

[0030] See Figure 4 and Figure 5, the central position of the tray 300 is threadedly connected to the connecting rod 100. Specifically, when setting, an M12 internal thread hole is opened at the central position of the tray 300, and the internal thread hole is threadedly connected to the external thread of the connecting rod 100. The tray 300 includes a second disc portion 310 and a circular convex portion 320 concentrically arranged on the second disc portion 310. The diameter of the circular convex portion 320 is smaller than the inner diameter of the packing 10, and the outer edge of the circular convex portion 320 is matched with the inner edge of the packing. When actually setting, the diameter of the circular convex portion 320 is slightly smaller than the inner diameter of the packing 10, so that the packing 10 can not only be sleeved on the circular convex portion 320, but also avoid large-range movement of the packing 10. The end face of the packing 10 is supported on the end face of the second disc portion 310.

[0031] See Figure 8 , when the compressor disassembles the packing, the second disc portion 310 is used to support the packing 10, and the outer edge of the circular convex portion 320 is used to limit the inner edge of the packing. When disassembling the packing 10, the connecting rod 100 passes through the packing flange 20, connects the tray 300 to the connecting rod 100, lifts the tray 300 to remove the flange bolt 30, and the packing falls smoothly.

[0032] See Figure 7 , when the compressor installs the packing, the pressure plate 200 is installed in advance, and then the assembled packing is placed between the pressure plate 200 and the tray 300. The tray 300 is tightened to firmly fix the packing 10. The first disc portion 210 and the second disc portion 310 are used to compact the packing from both sides respectively, and the outer wall of the cylindrical portion 220 and the outer edge of the circular convex portion 320 are used to limit the inner edge of the packing at the same time. Lift the installation flange bolt 30 upward, remove the tray 300, and draw out the connecting rod 100 and the pressure plate 200 from above, and the packing replacement is completed.

[0033] The above-mentioned compressor packing disassembly and assembly tooling is provided with a pressure plate 200 and a tray 300, which can firmly fix the packing without dislocation, ensure the smooth installation of the packing. When disassembling the packing, the tooling can be installed in advance, and the upper and lower personnel cooperate with each other, which can avoid the packing from falling when removing the flange bolt and cause injury to the operators, ensuring the operation safety.

[0034] See Figure 6 , in an embodiment, a first annular extrusion surface 211 is formed on the first disc portion 210 outside the cylindrical portion 220, and a second annular extrusion surface 311 is formed on the second disc portion 310 outside the circular convex portion 320. The first annular extrusion surface 211 and the second annular extrusion surface 311 are close to each other to extrude the packing.

[0035] See Figure 1 And Figure 6, in one embodiment, the radial width of the first annular extrusion surface 211 is greater than or equal to the radial width of the packing. The first annular extrusion surface 211 completely covers the end face of the packing. With such a setting, the packing can be extruded more comprehensively from one side.

[0036] In one embodiment, the radial width of the second annular extrusion surface 311 is greater than or equal to the radial width of the packing. The second annular extrusion surface 311 completely covers the end face of the packing. With such a setting, the packing can be extruded more comprehensively from the other side.

[0037] In one embodiment, the radial width of the first annular extrusion surface 211 is equal to the radial width of the second annular extrusion surface 311.

[0038] In one embodiment, external threads are respectively provided at both ends of the connecting rod 100.

[0039] In one embodiment, the axial length of the cylindrical portion 220 is greater than the axial length of the circular convex portion 320.

[0040] In one embodiment, the outer diameter of the cylindrical portion 220 is less than or equal to the diameter of the circular convex portion 320.
