One end of the first telescopic rod 32 is connected to the first pusher 31; affected by the action of the first pusher 31, the first ejector rod 321 of the first telescopic rod 32 can extend into the first assembly groove 21; to ensure that the first ejector rod 321 can reach the first assembly groove 21 directly and fix the copper sleeve in the round hole of the first extension part, therefore, the first ejector rod 321 penetrates through the second through hole 24.

[0029] The second limiting member 4 is provided with a second assembly groove 41. The second assembly groove 41 is used to abut against the second extension part 82 of the high-pressure shaft.

[0031] It should be noted that, in order to facilitate the first ejector rod 321 and the second ejector rod 521 to sleeve the copper sleeve, the diameters of the first ejector rod 321 and the second ejector rod 521 are equal to the inner diameter of the copper sleeve. At the same time, in order to prevent the copper sleeve from getting stuck in the second through hole 24, the diameter of the second through hole 24 is smaller than the outer diameter of the copper sleeve.

[0032] Further, the support component 6 is arranged between the first limiting member 2 and the second limiting member 4. Specifically, the support component 6 includes a fixed block 61 arranged on one side of the first limiting member 2. One end of the fixed block 61 is fixedly connected to the workbench 1, and the other end has a V-shaped groove 611 for abutting against the shaft body 83 of the high-pressure shaft. According to the length of the high-pressure shaft, in this embodiment, two fixed blocks 61 are provided, and these two fixed blocks 61 are distributed at intervals front and back and are both located on one side of the first limiting member 2.

[0033] The support assembly 6 further includes a slide rail 62 and a support block 63. The slide rail 62 is arranged along the length direction of the second ejector rod 521.

[0034] In this embodiment, the device for assembling a copper sleeve on a high-pressure shaft further includes an electric control assembly 7 arranged on the workbench 1. The electric control assembly 7 has a first button 71 for connecting to an external power supply, a second button 72 for controlling the opening and closing of the first pusher 31, and a third button 73 for controlling the opening and closing of the second pusher 51.

[0035] It should be noted that, in this embodiment, the first pusher 31 and the second pusher 51 are preferably hydraulic cylinders. Since hydraulic cylinders are commonly used technical means in the field of part assembly bench equipment, the hydraulic cylinders belong to the prior art and will not be described in detail in this article.

[0036] It should be emphasized that, in this embodiment, the basic working principle of the device for assembling a copper sleeve on a high-pressure shaft is as follows: In this embodiment, the device for assembling a copper sleeve on a high-pressure shaft fixes the high-pressure shaft on the workbench 1 through the fixing block 61 of the support assembly 6. The first assembly groove 21 of the first limiting member 2 can abut against the first extension portion 81 of the high-pressure shaft, and the round hole of the first extension portion 81 is aligned with the first through hole 23. The first positioning rod 22 slides out from the first through hole 23, and one end of the first positioning rod 22 is embedded in the round hole of the first extension portion 81 of the high-pressure shaft to position the first extension portion 81. One end of the first ejector rod 321 close to the first assembly groove 21 is sleeved with a copper sleeve, and then the user presses the second button 72, and the first pusher 31 is turned on. Affected by the action of the first pusher 31, the first ejector rod 321 moves towards the round hole of the first extension portion 81. Since the first through hole 23 and the second through hole 24 are coaxially arranged, the first ejector rod 321 ejects the first positioning rod 22 out of the round hole of the first extension portion 81 and at the same time fixes the copper sleeve in the round hole of the first extension portion 81, completing the assembly of the copper sleeve in the round hole of the first extension portion 81. Then the first ejector rod 321 moves away from the round hole of the first extension portion 81, and then the first pusher 31 is turned off. It should be noted that since there is only one round hole in the first extension portion 81 of the high-pressure shaft, it is only necessary to sleeve the copper sleeve once, and then perform the assembly operation of the copper sleeve in the round hole of the second extension portion 82.

[0037] After the bronze bushing of the first extension part 81 is assembled, the high-pressure shaft is transferred from the fixed block 61 and placed on the support block 63 for fixation. Then, the second extension part 82 of the high-pressure shaft is abutted against the second assembly groove 41 of the second limiting member 4, and the round hole of the second extension part 82 is aligned with the third through hole 43. The second positioning rod 42 slides out from the third through hole 43, and one end of the second positioning rod 42 is embedded in the round hole of the second extension part 82 of the high-pressure shaft to position the second extension part 82. One end of the second ejector rod 521 close to the second assembly groove 41 is sleeved with a bronze bushing. Then, the user presses the third button 73, and the second pusher 51 is activated. The second pusher 51 drives the second ejector rod 521 to move towards the direction of the round hole of the second extension part 82. Since the third through hole 43 and the second ejector rod 521 are coaxially arranged, the second ejector rod 521 ejects the second positioning rod 42 out of the round hole of the second extension part, and at the same time fixes the bronze bushing in the round hole of the second extension part 82. Then, the second ejector rod 521 moves away from the round hole of the second extension part 82, and then the second pusher 51 is closed. In this embodiment, since the high-pressure shaft has three second extension parts 82, that is, there are three round holes that need to be assembled with bronze bushings correspondingly. Through the above operations, after assembling the round hole of one of the second extension parts 82, the other two round holes are assembled in sequence. The specific operation is that after assembling one of the round holes, the second extension part 82 of the high-pressure shaft with the assembled bronze bushing is moved away from the second assembly groove 41. By sliding the support block 63 on the slide rail 62, the high-pressure shaft is moved left and right so that the other second extension parts 82 are abutted against the second assembly groove 41, and the assembly of the bronze bushing is completed through the above operations. The user controls the first pusher 31 and the second pusher 51 to embed the bronze bushing into the corresponding round hole respectively by pressing the second button 72 and the third button 73, and the assembly operation of the bronze bushing is completed, which greatly improves the efficiency of assembling the bronze bushing.

[0038] As mentioned above, the above is only the preferred specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, making non-substantive modifications to the present invention using this concept, shall fall within the scope of infringement of the protection of the present invention.
