[0031] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely represents some embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0034] like Figure 1-5 As shown, this embodiment provides a calibration device for installing a DC motor housing, comprising an operating table 1, a rotary calibration mechanism 2 is provided on the top of the operating table 1, a clamping assembly 3 is provided on one side of the operating table 1, and a limit assembly 4 is provided on the top of the operating table 1;

[0035] The rotation calibration mechanism 2 includes a first servo motor 201, a rotating column 202, a rotating block 203 and a placement slot 204. The first servo motor 201 is bolted to the bottom of the operating table 1, and the rotating column 202 is coaxially arranged at the output end of the first servo motor 201. The servo motor 201 drives the rotating column 202 to rotate. The rotating block 203 is fixedly connected to the top of the rotating column 202 and is located at the center of the rotating column 202. The placement slot 204 is opened inside the rotating block 203. The motor housing to be installed is placed in the placement slot 204 of the rotating block 203. During installation, the first servo motor 201 can be started to rotate the rotating column 202 and the rotating block 203, thereby driving the motor housing to rotate, so that the staff can observe whether the inner wall of the housing is aligned with the motor rotor.

[0036] like Figure 3As shown, the clamping assembly 3 includes a second servo motor 301, a bidirectional screw rod 302, a moving block 303, a slide 304, a support block 305, a fixed rod 306 and a clamping plate 307. The second servo motor 301 is bolted to one side of the operating table 1, and the bidirectional screw rod 302 is fixedly connected to the output end of the second servo motor 301. The two moving blocks 303 are both threadedly connected to the outer wall of the bidirectional screw rod 302 and are symmetrically arranged. The second servo motor 301 drives the bidirectional screw rod 302 to rotate, driving the two moving blocks 303 to move closer to or away from each other. There are two slide grooves 304, both of which are opened inside the operating table 1. The slide grooves 304 extend along the moving direction of the moving block 303. The support block 305 is fixedly connected to the top of the moving block 303 and is slidably connected to the inner wall of the slide groove 304. The support block 30 The two movable blocks 303 are inserted into the chute 304 and slide along the length direction of the chute 304. The outer wall of the support block 305 is tightly fitted with the inner wall of the chute 304. The fixing rod 306 is fixedly connected to one side of the support block 305. The clamping plate 307 is fixedly connected to one side of the fixing rod 306. After adjusting the motor housing, the second servo motor 301 is started to rotate the bidirectional screw rod 302, thereby causing the two movable blocks 303 to move towards or oppositely in the chute 304, thereby causing the support block 305 and the fixing rod 306 to approach the outer wall of the motor housing, so that the clamping plate 307 clamps and fixes them, thereby maintaining the stability of the motor housing during installation. When the motor housing is not adjusted properly and deviation occurs, the second servo motor 301 can be rotated in the opposite direction to make the two clamping plates 307 away from the motor housing, which is convenient for the staff to adjust it.

[0037] like Figure 5As shown, the limiting assembly 4 includes a support frame 401, a slide rod 402, a limiting plate 403, a waist-shaped hole 404, a first threaded column 405, a second threaded column 406 and an internal threaded sleeve 407. The two support frames 401 are fixedly connected to the top of the operating table 1, the slide rod 402 is fixedly connected to one side of the support frame 401, the limiting plate 403 is arranged below the support frame 401, the waist-shaped hole 404 is opened inside the limiting plate 403, the slide rod 402 is inserted into the waist-shaped hole 404, and the limiting plate 403 can move up and down on the slide rod 402 through the waist-shaped hole 404. The waist-shaped hole 404 is arranged along the length direction of the limiting plate 403, so that the slide rod 402 can slide along the length direction of the waist-shaped hole 404, so that the limiting plate 403 can move away from or close to the placement slot 204. The first threaded column 405 is fixedly connected to the limiting At the bottom of the positioning plate 403, the second threaded column 406 is fixedly connected to the top of the operating table 1, the internal threaded sleeve 407 is threadedly connected to the outer wall of the first threaded column 405, and the other end of the internal threaded sleeve 407 is threadedly connected to the outer wall of the second threaded column 406; the limiting assembly 4 is provided with at least two groups, and the two groups of limiting assemblies 4 are respectively located on both sides of the placement groove 204. When the motor rotor is placed into the motor housing, the internal threaded sleeve 407 is screwed into the bottom of the first threaded column 405, and then the limiting plate 403 is slid so that the limiting plate 403 is close to the top of the motor housing, and the bottom of the first threaded column 405 is located at the top of the second threaded column 406, and then the internal threaded sleeve 407 is rotated to make it enter the top of the second threaded column 406, so that the limiting plate 403 is close to the top of the motor housing, limiting it to prevent the motor housing from shaking during installation.

[0038] like Figure 3 As shown, the tops of the two limit plates 403 are fixedly connected to an extension plate 5, and a vertically arranged third threaded column 6 is passed through the extension plate 5. The third threaded column 6 and the extension plate 5 are threadedly connected, and a soft pad 7 is provided at the bottom of the third threaded column 6. After the motor rotor is placed in the motor housing, the third threaded column 6 can be rotated to make the soft pad 7 slowly descend to support the rotor in the housing to prevent it from shaking, so as to facilitate subsequent staff to further fix the rotor.

[0039] like Figure 4 As shown, a plurality of stabilizing grooves 8 are provided inside the operating table 1 and on the inner wall of the slide 304. The stabilizing grooves 8 extend along the length direction of the slide 304. Stabilizing blocks 9 are detachably connected to both sides of the support block 305. One end of the stabilizing block 9 is located in the stabilizing groove 8 and contacts the inner wall of the stabilizing groove 8. The stabilizing block 9 can slide along the length direction of the stabilizing groove 8. Since the stabilizing block 9 is connected to the support block 305 and the stabilizing block 9 is located on the inner wall of the stabilizing groove 8, when the support block 305 moves, the stabilizing block 9 will slide in the stabilizing groove 8, thereby improving the stability of the support block 305 during movement.

[0040] like Figure 3 As shown, a stabilizing rod 10 is fixedly connected to one side of the operating table 1. The stabilizing rod 10 is arranged parallel to the bidirectional screw rod 302 and is located below the bidirectional screw rod 302. The stabilizing rod 10 is passed through two moving blocks 303 and the moving blocks 303 can slide along the length direction of the stabilizing rod 10. When the moving blocks 303 move, they will synchronously slide on the outer wall of the stabilizing rod 10, which improves the stability of the moving blocks 303 during movement and can prevent the moving blocks 303 from rotating with the rotation of the bidirectional screw rod 302.

[0041] like Figure 3 As shown, protective pads 11 are welded on the two clamping plates 307. The protective pads 11 are set toward the outer wall of the product. The protective pads 11 are made of flexible material. When the clamping plates 307 clamp the motor housing, the protective pads 11 will directly contact the motor housing to prevent the clamping plates 307 from causing scratches or extrusion damage to the motor housing.

[0042] Specifically, when using the calibration device for installing a DC motor housing: place the motor housing to be installed into the placement slot 204 of the rotating block 203, start the first servo motor 201, rotate the rotating column 202 and the rotating block 203, and then drive the motor housing to rotate, so that the staff can observe whether the inner wall of the housing is aligned with the motor rotor. After adjusting the motor housing, start the second servo motor 301 to rotate the bidirectional screw rod 302, and then make the two moving blocks 303 move toward or oppositely in the slide slot 304, so that the support block 305 and the fixed rod 306 are close to the outer wall of the motor housing, so that the clamping plate 307 and the protective pad 11 clamp and fix them. When placing the motor rotor into the motor housing, screw the internal threaded sleeve 407 into the bottom of the first threaded column 405, then slide the limit plate 403 so that the limit plate 403 is close to the top of the motor housing, and make the bottom of the first threaded column 405 be located at the top of the second threaded column 406, then rotate the internal threaded sleeve 407 to make it enter the top of the second threaded column 406, so that the limit plate 403 is close to the top of the motor housing, limiting it to prevent the motor housing from shaking during installation. After placing the motor rotor into the motor housing, the third threaded column 6 can be rotated to make the soft pad 7 slowly descend to support the rotor in the housing to prevent it from shaking, making it easier for subsequent staff to further fix the rotor.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
