Description

Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a tooling for adjusting the inner support surface of a motor end cover. Background Art

[0002] The permanent magnet motor is composed of components such as a rotor, a stator and an end cover, among which the end cover is one of the most critical parts of the motor. The processing of the motor end cover generally requires the processing of the bearing chamber end and the resolver end of the end cover separately. In the prior art, the bearing chamber end of the end cover is usually processed first, and then the processed bearing chamber end stop is positioned and matched with the stop of the adjustment tooling. After positioning, due to a certain gap between the bearing chamber end and the adjustment tooling, the concentricity of the resolver hole, the bearing chamber hole and the oil seal hole is poor after the resolver end is processed. After the whole machine is assembled, due to the poor concentricity of the end cover, the oil seal life is reduced and the resolver accuracy cannot be controlled, thereby reducing the operating life of the motor. Utility Model Content

[0003] Based on this, a motor end cover inner support surface adjustment tool is provided, which can fit tightly with the bearing chamber end of the end cover, and can avoid the situation where the bearing chamber hole and the rotational transformer hole are not concentric after the end cover is processed.

[0004] A motor end cover inner support and surface adjustment tool comprises a connecting plate, on which a positioning mechanism and a supporting mechanism are arranged. The positioning mechanism is used to position and tighten the bearing chamber hole of the end cover, and the supporting mechanism is used to support the end cover and fit with the end surface of the end cover.

[0005] The support mechanism includes a plurality of support components arranged along the circumference of the outer ring of the connecting disk, an air block is arranged between the support component and the connecting disk, a No. 1 air vent is arranged on the air block, a No. 2 air vent is arranged in the support component, the No. 1 air vent is connected to one end of the No. 2 air vent, and the other end of the No. 2 air vent corresponds to the end surface of the end cover.

[0006] The above-mentioned motor end cover inner support and surface adjustment tooling is composed of a positioning mechanism and a supporting mechanism. The positioning mechanism positions and tightens the bearing chamber hole of the end cover, so that the supporting components of the supporting mechanism support the end cover respectively, and one end of the supporting component is tightly fitted with the end face of the end cover.

The machine tool's air inspection procedure can be used to check whether the end face of the end cover and the supporting component are firmly fitted. If there is air leakage, the next processing operation cannot be performed. The tooling can position the end cover and fit the end face of the end cover tightly to the supporting component through the positioning mechanism and the supporting mechanism, which can effectively avoid the situation where the bearing chamber hole and the rotating hole are not concentric after processing.

[0007] In one of the embodiments, the support assembly of the motor end cover internal support and surface adjustment tooling includes an arc-shaped fixing block and two support blocks. The arc-shaped fixing block is provided with a bayonet for connecting with a connecting plate. The two support blocks are symmetrically installed at both ends of the arc-shaped fixing block, and the two support blocks are respectively used to fit with the end faces of the end cover.

[0012] In one of the embodiments, a main shaft for connecting to a lathe is provided at the bottom of the connecting plate of the inner support and surface adjustment tooling of the motor end cover.

[0013] The beneficial effects of this application are:

[0014] The present application provides a tooling for adjusting the inner support surface of the motor end cover, which is composed of a positioning mechanism and a supporting mechanism. The positioning mechanism positions and tightens the bearing chamber hole of the end cover, so that the supporting components of the supporting mechanism support the end cover respectively, and one end of the supporting component is tightly fitted with the end face of the end cover. A No. 2 vent hole and a No. 1 vent hole are respectively arranged on the supporting component and the air passage block. One end of the No. 1 vent hole is connected to one end of the No. 2 vent hole, and the other end of the No. 1 vent hole is connected to the air path of the machine tool.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, an embodiment of the present application provides a motor end cover internal support and surface adjustment tooling, including a connecting plate 1, on which a positioning mechanism 2 and a supporting mechanism 3 are provided, the positioning mechanism 2 is used to position and tighten the bearing chamber hole 42 of the end cover 4, and the supporting mechanism 3 is used to support the end cover 4 and fit with the end surface of the end cover 4.

[0022] The support mechanism 3 includes a plurality of support components 31 arranged along the circumference of the outer ring of the connecting disk 1, an air block 32 is arranged between the support component 31 and the connecting disk 1, a No. 1 air vent is arranged on the air block 32, a No. 2 air vent is arranged in the support component 31, the No. 1 air vent is connected to one end of the No. 2 air vent, and the other end of the No. 2 air vent corresponds to the end surface of the end cover 4.

[0023] Specifically, the motor end cover inner support and surface adjustment tooling is composed of a positioning mechanism 2 and a supporting mechanism 3. The positioning mechanism 2 positions and tightens the bearing chamber hole 42 of the end cover 4. The supporting mechanism 3 includes three supporting components 31. The three supporting components 31 support the end faces of the end cover 4 respectively, and one end of the supporting component 31 is tightly fitted with the end face of the end cover 4. A second vent hole and a first vent hole are respectively set on the supporting component 31 and the air passing block 32. One end of the first vent hole is connected to one end of the second vent hole, and the other end of the first vent hole is connected to the air path of the machine tool. The other end of the second vent hole is fitted with the end face of the end cover 4. The air inspection procedure of the machine tool can be used to check whether the end face of the end cover 4 and the supporting component 31 are firmly fitted. If there is air leakage, the next processing operation cannot be performed.

[0024] In the above structure, by setting the No. 1 through hole and the No. 2 through hole, it is convenient for the gas inspection procedure to determine whether the end face of the end cover 4 is firmly attached to the support assembly 31. If there is a gap, the end cover 4 cannot be processed. The positioning mechanism 2 and the support mechanism 3 can also be used to position the end cover 4 and closely attach the end face of the end cover 4 to the support assembly 31, which can effectively avoid the situation where the bearing chamber hole 42 and the rotational change hole 41 are not concentric after processing.

[0025] like Figure 1 As shown, in one embodiment, the support assembly 31 of the motor end cover inner support and surface adjustment tooling includes an arc-shaped fixing block 311 and two support blocks 312, and the arc-shaped fixing block 311 is provided with a bayonet 001 for connecting with the connecting disk 1, and the two support blocks 312 are symmetrically installed at both ends of the arc-shaped fixing block 311, and the two support blocks 312 are respectively used to fit with the end faces of the end cover 4.

[0027] This arrangement facilitates supporting the end cover 4 and fitting with the end surface of the end cover 4 .

[0028] like Figure 1 and Figure 2 As shown, in one of the embodiments, the positioning mechanism 2 of the inner support and adjustment tooling of the motor end cover includes a plurality of fixing claws 21 arranged along the central circumference of the connecting disk 1, a boss is arranged at the bottom of the fixing claw 21, a plurality of connecting blocks 11 are arranged along the circumference of the connecting disk 1, and a tooth groove for fixing and cooperating with the boss is arranged on the connecting block 11, and a detachable supporting claw 22 is arranged on the fixing claw 21, and one end of the supporting claw 22 is used to extend into the bearing chamber hole 42 of the end cover 4 and tighten the bearing chamber hole 42 of the end cover 4.

[0029] Specifically, three fixing claws 21 can be arranged along the middle circumference of the connecting disk 1, and three connecting blocks 11 can be arranged on the connecting disk 1. The tooth grooves on the connecting blocks are fixedly matched with the bosses of the fixing claws. The fixing claw 21 is fixedly connected to the connecting blocks by bolts, and the supporting claw 22 is detachably connected to the fixing claw 21 by bolts. One end of the supporting claw 22 extends into the bearing chamber hole 42 of the end cover 4 to position the bearing chamber hole 42 and tighten the bearing chamber hole 42 so that the end cover 4 is fixed on the connecting disk 1.

[0030] In the above structure, the detachable support claw 22 is used for internal support, and there is no need to repeatedly use bolts for locking and fixing, which greatly improves the clamping efficiency. The specifications of the support claw 22 can also be replaced according to the model of the end cover 4, thereby improving the versatility of the tooling.

[0031] like Figure 2 As shown, in one of the embodiments, the fixing claw 21 of the motor end cover inner support and adjustment tooling is set to be L-shaped. This setting is convenient for accommodating the supporting claw 22.

[0032] like Figure 2 As shown, in one embodiment, the support claw 22 of the motor end cover inner support and surface adjustment tooling is set to be L-shaped.

[0033] This arrangement facilitates the support claws 22 to tighten the bearing chamber hole 42 of the end cover 4 .

[0034] like Figure 2 As shown, in one of the embodiments, the supporting claws 22 of the motor end cover inner support and surface adjustment tooling are soft claws.

[0035] The soft claws are used to facilitate tightening the bearing chamber hole 42 of the end cover 4.

[0036] like Figure 1 As shown, in one of the embodiments, a main shaft 12 for connecting to a lathe is provided at the bottom of the connecting plate 1 of the inner support and surface adjustment tooling of the motor end cover.

[0037] Specifically, the connection plate 1 is connected to the lathe through the main shaft 12. This arrangement facilitates the installation of the connection plate 1 on the lathe.
