Compressors are widely used in engineering and industrial fields, and are often used in refrigeration, air conditioning, water supply systems, industrial production and energy industries. The main function of a compressor is to increase the pressure of gas or steam and compress it into a smaller volume, so that the gas or steam can be more efficiently transported, stored or used to achieve a specific industrial process. Compressors require disassembly equipment when repairing.
[0003] The existing disassembly device is to place the compressor upside down on the tooling, adjust the position of the tooling feet so that the tooling feet are against the compressor bracket, use the hexagon socket to lock the screws and the side of the bottom cover, and use a wrench to twist the nut to remove the compressor bottom cover. However, since the force is applied to one side of the feet, the bottom cover is easily deformed, the bottom bearing installation size is not in place, and after the screws are locked with the side of the bottom cover, scratches will appear on the side of the bottom cover, resulting in a poor appearance of the compressor. In addition, the existing disassembly device cannot switch the compressor fixing method when fixing the compressor, and its applicability is insufficient.
[0004] Therefore, we make improvements to this and propose a compressor bottom cover disassembly tool. Utility Model Content

[0015] Compared with the prior art, the utility model has the following beneficial effects:
[0016] In the scheme of this application:
[0017] 1. Place the compressor in the lower tooling, clamp the shell with the cylinder, install the upper tooling on the bottom cover, and tighten it with screws.

[0029] Embodiment 1:
[0030] like Figure 1-Figure 4 As shown, this embodiment proposes a compressor bottom cover disassembly tool, including a clamping cylinder 1, a round handle 2 is arranged below the clamping cylinder 1, an upper tool 3 is arranged at the bottom of the round handle 2, a lower tool 4 is arranged below the upper tool 3, a support seat 5 is installed at the bottom of the lower tool 4, clamps 16 are arranged on both sides of the lower tool 4, a first connecting frame 6 and a second connecting frame 9 are fixedly connected on both sides of the support seat 5, a bidirectional screw 7 is rotatably connected in the first connecting frame 6, a first electric push rod 8 is installed on the support seat 5, and a first motor 1 is installed on the first electric push rod 8 0, an outer bushing 11 is connected to the output shaft of the first motor 10, and the outer bushing 11 is rotatably installed on the outside of the bidirectional screw 7. A clamping block 18 is arranged between the bidirectional screw 7 and the bidirectional screw 7. Slide blocks 12 are threadedly installed on both sides of the bidirectional screw 7. A support rod 15 is fitted inside the slider 12. The upper part of the support rod 15 is connected to the clamp 16. The position of the first motor 10 is changed by the first electric push rod 8, thereby changing the connection mode between the output shaft of the first motor 10 and the outer bushing 11 and the bidirectional screw 7, thereby changing the clamping mode of the device for the compressor.
[0031] Embodiment 2:
[0032] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:
[0033] like Figure 1As shown, as a preferred embodiment, on the basis of the above method, further, the support seat 5, the first connecting frame 6 and the second connecting frame 9 are a whole, and the lower surfaces of the support seat 5, the first connecting frame 6 and the second connecting frame 9 are in the same plane, ensuring that the device as a whole can prevent stability and enhance the stability of the device during operation.
[0034] like Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a groove 17 is opened in the bidirectional screw 7, a block 18 is arranged in the groove 17, a spring 19 is connected between the block 18 and the outer bushing 11, and the spring 19 can shrink the block 18 to the inside of the outer bushing 11 after the block 18 is compressed to a certain extent, thereby limiting the clamping degree of the device and enhancing the stability of the device.
[0035] like Figure 2 and Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the connection between the output shaft of the first motor 10 and the bidirectional screw 7 and the outer sleeve 11 is a key connection, and a keyway 20 is provided in the bidirectional screw 7 and the outer sleeve 11. The keyway 20 enables the device to change the connection method between the first motor 10 and the bidirectional screw 7 and the outer sleeve 11. When the first motor 10 is connected to the bidirectional screw 7 and the outer sleeve 11 at the same time, the bidirectional screw 7 can be directly driven to rotate. When the first motor 10 is only connected to the outer sleeve 11, the bidirectional screw 7 can be indirectly driven to rotate, and when the rotation resistance of the bidirectional screw 7 is too large, the bidirectional screw 7 is stopped from rotating, thereby realizing a protection function.
[0036] like Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a second electric push rod 13 is fixedly connected to the slider 12, and a convex plate 14 is fixedly connected above the second electric push rod 13. The convex plate 14 and the slider 12 are slidably connected, and the slider 12 and the support rod 15 are fixedly connected. The slidably mounted convex plate 14 can drive the support rod 15 to move upward stably when moving upward, so as to adjust the clamping height subsequently.
[0037] like Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the block 18 is a spherical structure, half of the diameter of the block 18 is larger than the depth of the groove 17, and the outer bushing 11 is suitable for sliding on the outside of the bidirectional screw 7 when the rotation resistance of the bidirectional screw 7 is too large, ensuring that the bidirectional screw 7 stops rotating when the rotation resistance is too large, and does not affect the normal rotation of the outer bushing 11, thereby realizing the function of overload protection.
[0038] Specifically, when the compressor bottom cover disassembly tool is used: Figure 1As shown, by placing the compressor into the lower tooling 4, the housing is clamped by the clamp 16. When clamping, as shown in FIG. Figure 2 and Figure 3 As shown, the height of the support rod 15 is adjusted according to the required clamping height. During the adjustment, the second electric push rod 13 on the slider 12 is extended or shortened, thereby changing the height of the convex plate 14, the support rod 15 and the clamp 16. After the adjustment is completed, the upper tooling 3 is installed on the bottom cover and locked with screws. The PLC is used to control the stroke of the servo motor so that the clamping claw cylinder 1 reaches the specified position and clamps the round handle 2. The servo motor controls the stroke to move upward, thereby slowly pulling out the bottom cover. In this way, the bottom cover will not be deformed, the bottom bearing will not deviate from the installation size, and there will be no scratches on the side of the bottom cover.
[0039] During the clamping of the housing, Figure 1 , Figure 2 and Figure 4 As shown, the clamping mode can be switched as needed. By extending the first electric push rod 8, the first motor 10 is driven to move backward. During the backward movement of the first motor 10, the output shaft of the first motor 10 is pulled out from the keyway 20 of the bidirectional screw 7 and remains in the keyway 20 of the outer bushing 11. At this time, the block 18 of the spherical structure is supported by the spring 19 in the outer bushing 11, thereby driving the bidirectional screw 7 to rotate, thereby realizing the torque transmission function. In the process of transmitting torque, the outer bushing 11 can also drive the bidirectional screw 7 to rotate synchronously. When the bidirectional screw 7 rotates, the two adjacent sliders 12 move toward each other, so that the housing is clamped by the clamp 16. After the housing is clamped, the rotation resistance of the bidirectional screw 7 increases, and the block 18 will detach from the inside of the groove 17 and move to the next groove 17, thereby realizing the function of automatically stopping the drive when the rotation resistance is too large, thereby ensuring that the housing will not be damaged during the clamping process.
[0040] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
