[0002] Reciprocating compressors are commonly used equipment in industrial production, and the disassembly and assembly of the piston head is one of the key processes in their maintenance and repair. The piston head and piston shaft are usually fixed by bolts or threads. When disassembling and assembling the piston head, it is necessary to stably fix the piston shaft to prevent it from rotating or moving, so as to ensure that the disassembly and assembly operations can be carried out smoothly, thereby ensuring that the piston head can be easily separated from or reliably connected to the piston shaft.

[0003] Currently, in the disassembly and assembly of reciprocating compressor piston heads, there is a lack of efficient and stable piston shaft fixing tools. Temporary tools or simple clamping methods are often used, which have problems such as insecure fixing, easy damage to the piston shaft surface, and cumbersome operation, affecting disassembly and assembly efficiency and quality, and increasing maintenance difficulty and time costs. Therefore, it is urgent to design a piston shaft fixing tool for the disassembly and assembly of reciprocating compressor piston heads to solve the above problems. Summary of the Invention

[0024] Please see Figure 1-2This utility model discloses a piston shaft fixing tool for disassembling and assembling the piston head of a reciprocating compressor, comprising a clamping assembly and a transfer hand ring 4. The clamping assembly includes a lower clamping seat 1, an upper clamping block 2, and a bolt assembly; the bolt assembly includes a connecting bolt 3 passing through a bolt through hole and a connecting nut 31 that mates with the connecting bolt 3.

[0025] The lower clamping base 1 provides basic support, with its bottom configured as a support plate. Force-bearing handles 11 are provided on the left and right sides for easy assembly and disassembly of the piston head. Through holes 13 for the transfer wristbands to pass through are provided on the front and rear sides. The upper surface is a first V-shaped groove 10, with two mounting ears formed on each side of the groove opening. Each mounting ear has a bolt through hole for the connecting bolt 3 to pass through. Two transfer wristbands 4 are provided, respectively connected to the through holes 13 on the front and rear sides of the lower clamping base 1.

[0026] The mounting ears on the first V-shaped groove 10 are connected to the bottom surface of the lower clamping seat 1 by a first reinforcing plate 12. The upper clamping block 2 is provided with a second V-shaped groove 20, and two mounting ears are formed on each side of the groove opening of the second V-shaped groove 20. The mounting ears are provided with bolt through holes for the connecting bolts 3 to pass through. The mounting ears on the second V-shaped groove 20 are connected to the outer wall of the upper clamping block by a second reinforcing plate 21.

[0027] The lower clamping seat 1 and the upper clamping block 2 are connected by a bolt assembly passing through the bolt through hole. In use, the piston shaft is placed between the first V-groove 10 and the second V-groove 20. By tightening the connecting nut 31, the distance between the first V-groove 10 and the second V-groove 20 can be reduced until the piston shaft is fixed. This design allows for the adjustment of the distance between the first V-groove 10 and the second V-groove 20 by the connecting nut 31, thus accommodating piston shafts of different diameters.

[0028] Furthermore, both the first clamping pad 5 and the second clamping pad 6 are wear-resistant, non-slip rubber pads or polymer composite material pads. The first clamping pad 5 is installed between the first V-shaped clamping groove 10 and the piston shaft; the second clamping pad 6 is installed between the second V-shaped clamping groove 20 and the piston shaft. In this way, the clamping friction on the piston shaft can be enhanced, while avoiding damage to the piston shaft surface during disassembly and assembly.

[0029] The steps for disassembling and assembling the piston shaft using this utility model are as follows:

[0030] S1. First, by lifting the transfer wristband 4, place the piston shaft fixing tool of this utility model at the compressor repair station.

[0031] S2. Maintenance personnel insert the first clamping pad 5 into the first V-shaped clamping groove 10 on the lower clamping seat 1, then place the piston shaft on the first clamping pad 5, cover it with the upper clamping block 2 on which the second clamping pad 6 is installed, insert the connecting bolt 3 and tighten the connecting nut 31, so that the distance between the first V-shaped clamping groove 10 and the second V-shaped clamping groove 20 is reduced until the piston shaft is clamped. The second clamping pad 6 and the first clamping pad 5 ensure stable clamping and do not damage the piston shaft.

[0032] S3. With the help of the force-bearing handles 11 on the left and right sides of the lower clamping seat 1, a stable force-bearing point is provided for the disassembly and assembly of the piston head.

[0033] S4. After disassembly and assembly, loosen the bolt assembly, remove the piston shaft, and place the piston shaft fixing tool of this utility model into the storage box by lifting the transfer wristband 4.

[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.
