[0002] Air compressors are usually composed of crankcases, motors, and dryers. Figure 1 As shown, when the staff removes the bearing 903 of the motor rotor assembly 9 from the bearing sleeve 30 of the crankcase 10, due to the interference fit between the bearing 903 of the rotor assembly 9 and the bearing sleeve 30, and the bearing glue seal, it is extremely inconvenient for the staff to remove it for maintenance or replacement. For the magnetic brushless motor rotor, it is easy to cause wear on the rotor surface when clamping and adjusting the rotor by using conventional disassembly tools; and the existing disassembly tools are difficult to apply to the disassembly of rotor assemblies of various specifications and sizes. Therefore, the utility model intends to provide a disassembly tool with strong applicability and no wear on the rotor surface during the disassembly process. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figures 1 to 5 As shown, the utility model provides a disassembly tool for an air compressor rotor assembly, comprising a gantry bracket 2, a mounting plate 3, an L-shaped clamping rod 4 and a V-shaped clamping sleeve 5.

[0027] The gantry bracket 2 is detachably mounted on the crankcase 10. A positioning sleeve 1 is mounted at the bottom of the gantry bracket 2 and can be mounted on the motor mounting sleeve 40 of the crankcase 10. This can improve the stability of the disassembly tooling and improve its positioning and installation efficiency relative to the crankcase 10.

[0028] A guide hole 203 is vertically opened on the vertical support rod 201 of the gantry bracket 2 , and the screw 8 passes through the guide hole 203 and is connected to the corresponding side threaded hole 20 of the crankcase 10 .

[0029] The mounting plate 3 is slidably disposed on the gantry bracket 2, and the height of the mounting plate 3 relative to the gantry bracket 2 is adjustable. Specifically:

[0030] The mounting plate 3 is driven to rise and fall by a driving assembly 7, and the driving assembly 7 includes a lead screw 701 vertically rotatably arranged on the horizontal support rod 202 of the gantry bracket 2. The mounting plate 3 is fitted onto the lead screw 701 through a lead screw nut 702, and the lead screw 701 is driven to rotate by a pin rod 703 installed at the top. A guide groove 204 is vertically opened on the inner wall of the vertical support rod 201 of the gantry bracket 2, and guide blocks 302 that can vertically slide along the guide groove 204 are installed on both sides of the mounting plate 3.

[0031] The L-shaped clamping rods 4 are located on both sides of the gantry bracket 2 and are mounted on the mounting plate 3 and arranged opposite to each other. The L-shaped clamping rods 4 include a vertical rod 401 horizontally slidably arranged on the mounting plate 3 and a horizontal support plate 402 installed at the bottom end of the vertical rod 401. The horizontal support plate 402 is used to support the bottom surface of the rotor 901. Specifically:

[0032] The two sides of the mounting plate 3 are provided with slide grooves 301, and the vertical rods 401 are horizontally slidably arranged on the slide grooves 301 on the corresponding sides, and the outer ends of the slide grooves 301 are open. In this way, the L-shaped clamping rod 4 is connected to the mounting plate 3 in a shell-detachable manner, which will not interfere with the thermal drying step of the connection part of the rotor assembly 9.

[0033] The V-shaped clamping sleeve 5 is vertically slidably sleeved on the vertical rod 401, and a sleeve hole 501 is provided in the middle of the V-shaped clamping sleeve 5 for vertically penetrating the vertical rod 401. The V-shaped clamping wall 502 inside the V-shaped clamping sleeve 5 can be tangent to the side wall of the rotor 901.

[0034] Furthermore, the V-shaped clamping sleeve 5 is made of non-ferromagnetic material, and the vertical rod 401 is made of ferromagnetic material. For example, the V-shaped clamping sleeve 5 is made of lightweight plastic material, and the vertical rod 401 is made of iron material with adsorption force. The advantages of this arrangement are:

[0035] On the one hand, under the adsorption force of the brushed motor rotor 901, the two sets of L-shaped clamping rods 4 can be moved closer to the rotor 9, so that the V-shaped clamping sleeve 5 mounted on the vertical rod 401 can position and clamp the rotor 901 therebetween; on the other hand, the vertical rod 401 will not directly act on the side wall of the rotor 901. When the L-shaped clamping rod 4 is adjusted in height, the original friction between the vertical rod 401 and the side wall of the rotor 901 can be converted into friction between the vertical rod 401 and the sleeve hole 501 of the V-shaped clamping sleeve 5, thereby avoiding wear on the surface of the rotor 901.

[0036] Preferably, a rubber anti-skid pad may be provided on the V-shaped clamping wall 502 on the inner side of the V-shaped clamping sleeve 5 , so as to increase the friction between the rotor 901 and the V-shaped clamping sleeve 5 .

[0037] The working principle of the disassembly tool of the utility model is:

[0038] When removing the rotor assembly 9 from the crankcase 10, first, the positioning sleeve 1 is mounted on the motor mounting sleeve 40 of the crankcase 10, and the guide hole 203 on the gantry bracket 2 is aligned with the threaded hole 20 on the crankcase 10. The gantry bracket 2 is fixedly mounted on the crankcase 10 using screws 8.

[0039] Afterwards, a heating device (not shown in the figure), such as a hot air blower, is used to heat the bearing 903 of the rotor assembly 9 and the bearing sleeve 30 mounted thereon, so as to soften the bearing glue therebetween, thereby facilitating the later disassembly operation between the two.

[0040] Next, the vertical rods 401 of the two L-shaped clamping rods 4 are slid and clamped into the slide grooves 301 from both ends. At this time, the horizontal support plate 402 at the bottom of the L-shaped clamping rod 4 is located at the horizontal height between the rotor 901 and the lower bearing 903. The two L-shaped clamping rods 4 are pushed toward the side close to the rotor 901. At the same time, under the adsorption force of the brushless motor rotor 901, the V-shaped clamping wall 502 of the inner wall of the V-shaped clamping sleeve 5 mounted on the vertical rod 401 can be tangent to the outer wall of the rotor 901.

[0041] Then, adjust the height of the L-shaped clamping rod 4 so that the surface of the horizontal support plate 402 is supported on the bottom surface of the rotor 901. Specifically:

[0042] The pin rod 703 is rotated to rotate the lead screw 701, and the mounting plate 3 which is mounted on the lead screw 701 through the lead screw nut 702 rises vertically under the guidance of the guide groove 204 on the inner side of the gantry bracket 2. During the rising process, the horizontal support plate 402 at the bottom end of the L-shaped clamping rod 4 will gradually contact the bottom surface of the rotor 901, and provide an upward pulling force to the rotor 901, and finally pull the rotor assembly 9 out of the bearing sleeve 30.

[0043] Since the V-shaped clamping wall 502 of the inner wall of the V-shaped clamping sleeve 5 has a centering function on the rotor 901 , the rotor assembly 9 will not fall off easily after being pulled out.

[0044] The disassembled rotor assembly 9 can be easily taken out by opening the L-shaped clamping rod 4, and the disassembly of the disassembly tooling can be completed by loosening the screws 8.

[0045] The utility model slides a V-shaped clamping sleeve 5 on the L-shaped clamping rod 4. On the one hand, under the adsorption force of the brushed motor rotor 901, the two groups of L-shaped clamping rods 4 can be moved closer to the rotor 9, so that the V-shaped clamping sleeve 5 mounted on the vertical rod 401 can position and clamp the rotor 901 therebetween, which is suitable for clamping rotors of various specifications and sizes, improves the positioning and clamping efficiency of the rotor 901, and can also prevent the rotor assembly 9 from easily falling off when being pulled out;

[0046] On the other hand, the vertical rod 401 will not directly act on the side wall of the rotor 901. When the L-shaped clamping rod 4 is adjusted in height, the original friction between the vertical rod 401 and the side wall of the rotor 901 can be converted into friction between the vertical rod 401 and the sleeve hole 501 of the V-shaped clamping sleeve 5, thereby avoiding wear on the surface of the rotor 901. The overall efficiency of disassembly of the rotor assembly is improved.

[0047] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
