Description

Technical Field

[0001] The present application relates to the field of compressor stator-rotor gap assembly, and in particular to a tool for assembling the compressor stator-rotor gap. Background Art

[0002] The stator and rotor of the compressor need to be gap-assembled during installation. At present, the existing tooling for assembling the gap between the stator and rotor of the compressor mainly uses an umbrella gauge, which usually includes a main body and eight gap pieces provided on the main body. The eight gap pieces are evenly distributed on the main body, and each gap piece is fixed to the main body by two screws. In this way, eight gap pieces require 16 screws. Therefore, when the eight gap pieces need to be replaced, all 16 screws need to be removed before the old eight gap pieces can be removed, and then the eight new gap pieces are replaced, and then the 16 screws are reinstalled on the main body, and then the new eight gap pieces are re-fixed on the main body. This process makes the process of replacing eight new gap pieces not only cumbersome, but also inefficient and slow. At the same time, the labor intensity of the staff is high. Based on this, the inventor has developed a new tooling for compressing the stator and rotor gap assembly with a fast replacement speed of eight gap pieces. Summary of the Invention

[0003] In order to improve the speed and efficiency of replacing the stator and rotor gap sheets of the compressor, the present application provides a tool for assembling the stator and rotor gap of the compressor. During disassembly and assembly, it is only necessary to disassemble the screw and the umbrella skirt, then remove the umbrella skirt from the main body, and then remove the eight gap sheets from the positioning assembly on the main body in turn, and then install the new gap sheets on the positioning assembly in turn, and then re-sleeve the umbrella skirt on the main body, and connect and fix the screw and the umbrella skirt to complete the replacement of the gap sheet. The process of replacing the gap sheet is not only fast and efficient, but also has low labor intensity. Compared with the traditional method of fixing the gap sheet with screws, it greatly improves the speed and efficiency of replacing the gap sheet.

[0024] The present application is further described in detail below with reference to the accompanying drawings.

[0025] The embodiment of the present application discloses a tool for assembling the gap between the stator and rotor of a compressor.

[0026] Reference Figure 1 The tooling includes a main body 1, a gap piece 2, a positioning component 3, an umbrella skirt 4 and a screw 5.

[0027] Reference Figure 1 and Figure 2 A first through hole 11 is opened in the middle of the main body 1 along its axial direction.

[0028] There are eight gap sheets 2, and each gap sheet 2 is provided with a positioning hole 21, wherein the number of positioning holes 21 on each gap sheet 2 is at least two, and at least two positioning holes 21 are arranged along the length direction of the gap sheet 2, and the eight gap sheets 2 are evenly distributed on the main body 1 along the circumferential direction of the main body 1.

[0029] Reference Figure 1 and Figure 2 The number of positioning assemblies 3 is the same as the number of gap pieces 2, also eight. Eight sets of positioning assemblies 3 are used to secure the eight gap pieces 2, and the eight sets of positioning assemblies 3 are evenly distributed along the circumference of the body 1. Each set of positioning assemblies 3 includes at least two positioning rods 31, wherein the positioning rods 31 are arranged along the radial direction of the body 1. The positioning rods 31 cooperate with the positioning holes 21 and pass through the positioning holes 21 in the gap pieces 2, thereby enabling the positioning assembly 3 to position the gap pieces 2. Specifically, the positioning rods 31 can be positioning pins, wherein a positioning groove 12 is defined on the outer wall of the body 1, and the positioning pins are inserted into the positioning groove 12.

[0030] Reference Figure 1 and Figure 3The shed 4 is sleeved on the exterior of the body 1. Specifically, one end of the shed 4 is open, and the other end is a solid rod. The open end of the shed 4 is sleeved on the body 1, and a second through-hole 41 is formed on the open end of the shed 4 for the positioning assembly 3 on the body 1 to pass through. In other words, the purpose of the second through-hole 41 is to make room for the positioning assembly 3, facilitating the installation of the shed 4 on the body 1. The shed 4 is used to press and secure the eight spacers 2 to the body 1. Specifically, to ensure that the shed 4 and the body 1 secure the eight spacers 2 more securely, the outer surface of the body 1 is an outer conical surface 14, and the inner wall of the open end of the shed 4 is an inner conical surface 42 that cooperates with the outer conical surface 14 of the body 1. When in use, the inner conical surface 42 is sleeved on the spacers 2, and the inner conical surface 42 and the outer conical surface 14 compress and secure the spacers 2.

[0031] Reference Figure 1 and Figure 3 The screw 5 passes through the first through hole 11 on the body 1 and is threadedly connected to the solid rod of the shed 4. The head of the screw 5 abuts against the body 1, thereby achieving a fixed connection between the shed 4 and the body 1. Specifically, an internal threaded hole 43 is formed on the solid rod of the shed 4, and the screw 5 is threadedly connected to the internal threaded hole 43 on the shed 4. The screw 5 is a hexagonal screw.

[0032] Further, refer to Figure 1 and Figure 2 In order to enable eight gap pieces 2 to be simultaneously installed on the body 1, the positioning assembly 3 further includes a magnet 32, which is disposed on the outer wall of the body 1 and is used to attract the gap pieces 2 mounted on the two positioning pins. Specifically, an adsorption groove 13 is defined on the outer wall of the body 1, and the magnet 32 is disposed within and embedded in the adsorption groove 13. Preferably, the magnet 32 and the adsorption groove 13 are of the same size and height, so that the magnet 32 does not protrude from the adsorption groove 13 and interfere with the installation of the gap pieces 2.

[0033] After the chute 1 is in operation, the chute 1 is automatically disconnected from the support 1 and the chute 1 is automatically disconnected, and the chute 1 is automatically disconnected from the support 1. When the chute 1 is in operation, the chute 1 is automatically disconnected from the support 1 and the chute 1 is automatically disconnected.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
