[0025] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0026] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present application.

[0027] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] like Figure 1-Figure 5 The processing auxiliary device for the reducer lower shell shown in the figure includes a positioning component 1, and the positioning component 1 is used to fix the reducer lower shell. The positioning component 1 is installed on the positioning support component 2, and the positioning support component 2 is fixedly installed on the placement plate 3. The placement plate 3 is provided with a radially arranged pre-tightening slide rail 301 to adapt to reducer lower shells of different sizes. A plurality of clamping cylinders 4 are installed on the placement plate 3, and the clamping cylinders 4 are slidably connected to the pre-tightening slide rail 301.

[0029] When processing the outer surface or external shaft hole of the reducer, first use the clamping cylinder 4 to clamp the outer surface of the lower shell of the reducer for pre-positioning. After the lower shell of the reducer is straightened, use the positioning component 1 to position the inner surface of the lower shell of the reducer to ensure accurate positioning. After the positioning component 1 positions the inner surface of the lower shell of the reducer, the clamping cylinder 4 stops working, and then the next step of processing of the lower shell of the reducer can be carried out.

[0030] like Figure 4 As shown, the positioning assembly 1 includes a connecting body 101, on which a plurality of arc-shaped positioning blocks 102 are fixedly mounted and evenly distributed on the circumference of the connecting body 101, and each arc-shaped positioning block 102 is provided with an arc-shaped slide rail 1021. The positioning assembly 1 is also provided with a plurality of telescopic arm assemblies 103, and each arc-shaped positioning block 102 is provided with a telescopic arm assembly 103, and the telescopic arm assembly 103 is slidably connected to the arc-shaped slide rail 1021.

[0031] like Figure 5 As shown, the telescopic arm assembly 103 includes a telescopic arm shaft 1031, one end of which is provided with an arc-shaped slider 10311, which is installed in the arc-shaped slide rail 1021 of the arc-shaped positioning block 102, and the arc-shaped slider 10311 is slidably connected to the arc-shaped slide rail 1021. The movable range of each arc-shaped slider 10311 in the arc-shaped slide rail 1021 is 80°, which is suitable for the inner surface of the reducer lower housing at different angles.

[0032] The other end of the telescopic arm shaft 1031 is equipped with a telescopic arm 1034, which is screwed and connected to the telescopic arm shaft 1031, and the telescopic arm 1034 can be telescopically adjusted. A movable shaft head 1035 is installed at one end of the telescopic arm 1034, and the movable shaft head 1035 is connected to the telescopic arm 1034 through a joint bearing. The movable shaft head 1035 is rotatably connected to the telescopic arm 1034, and the movable shaft head 1035 can rotate within a certain circumferential angle, so that the movable shaft head 1035 has a self-adjusting effect and can be used for compression planes of different angles. The locking spacer 1032 is sleeved on the telescopic arm shaft 1031, and the locking spacer 1032 is provided with an arc surface 10321. Two locking nuts 1033 are also provided on the telescopic arm shaft 1031, one locking nut 1033 is used to fix the telescopic arm shaft 1031, and the other locking nut 1033 is used to fix the telescopic arm 1034.

[0033] Combination Figure 2 and Figure 3The positioning support assembly 2 includes a hydraulic cylinder 201, which drives a support shaft 202 to move up and down. The support shaft 202 is an inverted L-shaped one. One end of the support shaft 202 is connected to the hydraulic cylinder 201, and the other end is provided with a lifting shaft hole 2021. Two radially arranged sliding keys 204 are installed in the lifting shaft hole 2021. The lifting shaft 203 is sleeved in the lifting shaft hole 2021. The lifting shaft 203 is radially provided with two sliding grooves 2031. The lifting shaft 203 is slidably connected in the lifting shaft hole 2021 through the sliding grooves 2031 and the sliding keys 204. The outer circumference of the lifting shaft 203 is provided with threads, and two lifting fixing nuts 205 are screwed on the lifting shaft 203. The two lifting fixing nuts 205 are respectively located on the upper surface and the lower surface of the lifting shaft hole 2021. When the lifting shaft 203 needs to be adjusted up and down, first loosen the lower lifting fixing nut 205, and then rotate the upper lifting fixing nut 205 to make the lifting shaft 203 move up and down. When it is adjusted to a suitable position, tighten the lower lifting fixing nut 205 to fix the position of the lifting shaft 203.

[0034] The up and down movement of the lifting shaft 203 can drive the up and down movement of the positioning assembly 1. The positioning assembly 1 is connected to the lifting shaft 203 through the connecting body 101. Figure 4 As shown, a connection positioning member 1011 is also provided on the connection body 101 to facilitate accurate positioning of the connection body 101 and the lifting shaft 203 .

[0035] When not in processing, the hydraulic cylinder 201 drives the support shaft 202 to move upward to a certain height, and the lifting shaft 203 drives the positioning assembly 1 to move upward to a certain height. When processing is required, the reducer lower shell is placed on the placement plate 3, and the outer surface of the reducer lower shell is clamped by the clamping cylinder 4 for pre-positioning, and then the hydraulic cylinder 201 drives the support shaft 202 to move downward to a suitable position, and the lifting shaft 203 drives the positioning assembly 1 to move downward to a certain position, and the lower end surface of the connecting body 101 presses the inner bottom surface of the reducer lower shell, and then adjusts the telescopic arm assembly 103 to a suitable angle and length, rotates the two locking nuts 1033, and fixes the telescopic arm shaft 1031 and the telescopic arm 1034. Because the arc surface 10321 is consistent with the outer cylindrical surface size of the arc positioning block 102, when tightening the locking nut 1033, the arc surface 10321 fits the arc positioning block 102, making the locking more secure, and the telescopic arm assembly 103 supports the various inner surfaces of the reducer lower shell for the next step of processing.

[0036] The implementation methods of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
