Description

Technical Field

[0001] This utility model relates to the technical field of compressor disassembly equipment, specifically a rotor heat jacket disassembly device. Background Technology

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of a refrigeration system. A compressor mainly consists of a cylinder structure, a transmission structure, and a body structure. The transmission structure is mainly driven by a crankshaft. When disassembling a compressor, the crankshaft and the rotor mounted on the crankshaft need to be removed.

[0003] Currently, after the rotor is heat-shrinked and naturally cooled, the rotor's inner diameter becomes smaller and it has an interference fit with the crankshaft's long shaft. When the hole is restored, a clamping force is generated on the shaft, connecting the two parts and making them difficult to disassemble. Conventional hammering methods will damage the crankshaft and rotor, reducing the efficiency of rotor heat-shrinking disassembly. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rotor heat jacket disassembly device, which solves the problem of inconvenience in quickly disassembling the rotor heat jacket from the crankshaft during compressor disassembly.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned goal of facilitating the rapid disassembly of the rotor heat jacket from the crankshaft during compressor disassembly, this utility model provides the following technical solution: a rotor heat jacket disassembly device, comprising a working platform, an inner groove formed inside the working platform, a hydraulic press disposed inside the inner groove, a lower support plate fixed on the working platform, a support rod fixed on the outer surface of the lower support plate, an upper support plate fixed on the support rod, a hydraulic cylinder fixed above the upper support plate, a hydraulic rod fixed at the output end of the hydraulic cylinder, an ejector rod fixed at the bottom end of the hydraulic rod, and a positioning fixture disposed on the inner surface of the lower support plate;

[0008] The positioning fixture includes a U-shaped platform, which is fixed to the inner side of the surface of the lower support plate. Slots are provided on both sides of the U-shaped platform. A first unloading support plate is inserted into the slot on one side, and a second unloading support plate is inserted into the slot on the other side. A rotor placement groove is provided on the upper surface of the first and second unloading support plates, and a through hole is provided on the bottom surface of the rotor placement groove.

[0009] Preferably, the rotor placement groove on one side of the No. 1 unloading support plate and the rotor placement groove on one side of the No. 2 unloading support plate are both semi-circular, and the rotor placement grooves on both sides form a circular groove.

[0012] Preferably, the first unloading support plate and the second unloading support plate are movably connected to the U-shaped platform via slots.

[0013] Preferably, the hydraulic rod, ejector rod, rotor placement slot, and through hole are on the same axis.

[0014] Preferably, the support rods are rectangular in shape and there are four of them, with the four support rods located on the outside of the positioning fixture.

[0015] Compared with the prior art, this utility model provides a rotor heat jacket disassembly device, which has the following beneficial effects:

[0016] 1. This rotor heat sleeve disassembly equipment, by placing the rotor into the rotor placement slot, aligns the crankshaft with the through hole, enabling the hydraulic cylinder to drive the hydraulic rod to automatically align with the bottom of the crankshaft long shaft, and the crankshaft is pressed out of the rotor by the ejector rod. The rotor remains on the rotor placement slot, and the ejected crankshaft falls onto the U-shaped platform through the through hole, completing the disassembly process, thus improving the efficiency of rotor heat sleeve disassembly.

[0017] 2. The rotor heat sleeve disassembly device, after the rotor is placed into the rotor placement slot, makes the hydraulic rod, ejector rod, rotor placement slot and through hole on the same axis. The hydraulic rod drives the ejector rod to move downward to push the crankshaft out of the rotor, so that the crankshaft and rotor are separated.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0025] Please see Figure 1-5 This utility model provides a rotor heat jacket disassembly device, including a working platform 1, an inner groove 2 is opened inside the working platform 1, a hydraulic press 3 is arranged inside the inner groove 2, a lower support plate 4 is fixed on the working platform 1, a support rod 5 is fixed on the outer surface of the lower support plate 4, an upper support plate 6 is fixed on the support rod 5, a hydraulic cylinder 7 is fixed above the upper support plate 6, a hydraulic rod 8 is fixed at the output end of the hydraulic cylinder 7, an ejector rod 9 is fixed at the bottom end of the hydraulic rod 8, and a positioning fixture 10 is arranged on the inner surface of the lower support plate 4.

[0026] The positioning fixture 10 includes a U-shaped platform 11, which is fixed to the inner side of the surface of the lower support plate 4. Slots 12 are provided on both sides of the U-shaped platform 11. A first unloading support plate 13 is inserted into the slot 12 on one side, and a second unloading support plate 14 is inserted into the slot 12 on the other side. A rotor placement groove 15 is provided on the upper surface of the first unloading support plate 13 and the second unloading support plate 14. A through hole 16 is provided on the bottom surface of the rotor placement groove 15. By inserting the first unloading support plate 13 and the second unloading support plate 14 into the slots 12 on both sides of the U-shaped platform 11, the pump body to be disassembled is taken out, and the rotor is placed into the rotor placement groove 15 so that the crankshaft is aligned with the through hole 16 so that the crankshaft can be automatically pushed out of the rotor later.

[0027] Furthermore, the rotor placement groove 15 on one side of the first unloading support plate 13 and the rotor placement groove 15 on one side of the second unloading support plate 14 are both semi-circular, forming a circular groove on both sides, which makes it easy to put the rotor into the rotor placement groove 15 so that the crankshaft can be ejected later.

[0028] Furthermore, the through holes 16 on one side of the No. 1 unloading support plate 13 and the through holes 16 on one side of the No. 2 unloading support plate 14 are both semi-circular, and the through holes 16 on both sides form round holes, so that the crankshaft after being ejected can fall down through the through holes 16.

[0029] Furthermore, the No. 1 unloading support plate 13 and the No. 2 unloading support plate 14 are symmetrically arranged. When the ejector rod 9 ejects the crankshaft, the No. 1 unloading support plate 13 and the No. 2 unloading support plate 14 are subjected to downward pressure, which facilitates the rotor to be supported and fixed through the No. 1 unloading support plate 13 and the No. 2 unloading support plate 14 on both sides.

[0030] Furthermore, the first unloading support plate 13 and the second unloading support plate 14 are movably connected to the U-shaped platform 11 through the slot 12. By moving the first unloading support plate 13 and the second unloading support plate 14 laterally, the first unloading support plate 13 and the second unloading support plate 14 can drive the rotor to move and align the rotor with the ejector rod 9.

[0031] Furthermore, the hydraulic rod 8, ejector rod 9, rotor placement slot 15, and through hole 16 are on the same axis. After the rotor is placed into the rotor placement slot 15, by making the hydraulic rod 8, ejector rod 9, rotor placement slot 15, and through hole 16 on the same axis, the hydraulic rod 8 drives the ejector rod 9 to move downward to eject the crankshaft from the rotor, thereby separating the crankshaft from the rotor. This allows the crankshaft to be automatically ejected from the rotor, reducing the occurrence of crankshaft and rotor defects after the rotor heat jacket is disassembled.

[0032] Furthermore, there are four rectangular support rods 5 located on the outside of the positioning fixture 10. The four support rods 5 can support and fix the upper support plate 6, so that the upper support plate 6 can support and fix the hydraulic cylinder 7.

[0033] In use, the No. 1 unloading support plate 13 and the No. 2 unloading support plate 14 are inserted into the slots 12 on both sides of the U-shaped platform 11, so that the rotor placement slots 15 on both sides of the No. 1 unloading support plate 13 and the No. 2 unloading support plate 14 form circular slots, and the through holes 16 on both sides form circular holes. Then, the pump body to be disassembled is taken out, and the rotor is placed into the rotor placement slot 15, so that the crankshaft is aligned with the through hole 16, and the rotor, crankshaft, ejector rod 9, rotor placement slot 15 and through hole 16 are on the same axis. The hydraulic cylinder 7 is activated, so that the hydraulic cylinder 7 can drive the hydraulic rod 8 to automatically align with the bottom of the crankshaft long shaft, and the crankshaft is pressed out of the rotor through the ejector rod 9. During this process, the rotor remains on the rotor placement slot 15. After being ejected, the crankshaft falls onto the U-shaped platform 11 through the through hole 16, completing the disassembly process and improving the efficiency of rotor heat sleeve disassembly.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
