Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0022] See also Figure 1 - Figure 5, including: an operating table 1; a punching machine 2 is installed on the operating table 1, the punching machine 2 is a prior art, and can automatically perform a punching operation by presetting.

The output end of the motor 31 is connected to a first gear 32. The first gear 32 is located on the operating table 1. A second gear 33 is rotatably installed on the operating table 1. The first gear 32 is meshed with the second gear 33. A turntable 34 is connected to the second gear 33. A lever 35 is connected to the turntable 34. A rotating shaft 36 is rotatably mounted on the operating table 1, the top of the rotating shaft 36 is connected to a chassis 38, the outer wall of the rotating shaft 36 is connected to a groove wheel 37, the groove wheel 37 is provided with four arc grooves and four straight grooves, the four straight grooves are arranged in a circular array with the center of the groove wheel 37 as the center, and the four arc grooves are arranged in a circular array with the center of the groove wheel 37 as the center. The lever 35 contacts the four straight grooves in turn during the movement, and the lever 35 contacts one of the straight grooves on the groove wheel 37 during the rotation, so that the lever 35 drives the groove wheel 37 to rotate through the straight groove when rotating. When the groove wheel 37 rotates to ninety degrees, the lever 35 is out of contact with the straight groove, and the lever 35 performs a second circle When rotating, it will contact another straight groove and drive the slide wheel 37 to rotate 90 degrees. Every time the lever 35 rotates one circle, it can drive the slide wheel 37 to rotate 90 degrees through one of the straight grooves. Four connecting blocks 39 are installed on the chassis 38. Cover plates 314 are installed on the tops of the four connecting blocks 39. Four sliders 310 are slidably installed on the chassis 38. Two connecting rods 311 are hinged on the sliders 310. The ends of the connecting rods 311 away from the sliders 310 are hinged with support rods 312. The eight support rods 312 are divided into four groups. The two support rods 312 between two adjacent connecting blocks 39 form a group. The four groups of support rods 312 are arranged in a circular array with the center of the chassis 38 as the center. The bottom surfaces of the support rods 312 are connected by springs. The elastic rod 313 is connected, and the eight support rods 312 are all slidably connected to the chassis 38. The staff puts the motor housing on the two support rods 312 of the same group. After the motor housing is put on the two support rods 312, the two elastic rods 313 exert a supporting force on the inner wall of the motor housing through the elastic force of the spring, so that the two support rods 312 and the two elastic rods 313 support and fix the motor housing from the inside, achieving a clamping effect. A spring is connected between the support rod 312 and one side of one of the connecting blocks 39 close to the support rod 312. Since the two support rods 312 support from the inside of the motor housing, the downward pressure generated by the punching machine 2 when punching is partially offset, greatly reducing the possibility of motor deformation;The inner wall of the cover plate 314 is slidably connected with a frustum block 315, and a threaded rod 316 is rotatably installed on the chassis 38. The threaded rod 316 is provided with a threaded groove. The inner wall of the frustum block 315 is slidably connected with the threaded groove on the threaded rod 316 through a ball.

The frustum block 315 is provided with four inclined surfaces, and the four inclined surfaces on the frustum block 315 are slidably connected with the four sliders 310 respectively. When the slider 310 moves in the direction away from the frustum block 315, the two connecting rods 311 drive the two struts 312 to move in the direction away from each other, thereby increasing the distance between the two struts 312. After the frustum block 315 moves upward, the slider 310 uses the reverse thrust generated by the two struts 312 to move along the inclined surface of the frustum block 315 toward the frustum block 315. The two support rods 312 move toward each other, thereby reducing the distance between the two support rods 312. By adjusting the distance between the two support rods 312, it is possible to adapt to motor housings with different inner diameters. The staff can adjust the distance between the two support rods 312 by turning the hand wheel 317 according to actual processing requirements to meet the support requirements and maintain the stability of the motor housing. Through the setting of the support assembly 3, the two support rods 312 and the two elastic rods 313 cooperate to support and fix the inside of the motor housing. When the two support rods 312 rotate to transport the motor housing to the bottom of the punching machine 2 for punching, the internal support method can avoid the deformation of the motor housing during punching as much as possible, thereby improving the product quality. The staff can adjust the distance between the two support rods 312 by turning the hand wheel 317 according to the processing requirements of motors of different specifications, so that the two support rods 312 can maintain the stability of the support, thereby enhancing the applicability of the support assembly 3. ;

[0023] For further information, see Figure 6 - Figure 7, a cleaning component 4 is used to clean the motor housing after punching. The cleaning component 4 is arranged on the operating table 1.

A collecting box 49 is installed on the operating table 1. The collecting box 49 is located below the cleaning brush 48. The cleaning brush 48 is flexibly arranged. When the motor housing is in motion, the cleaning brush 48 contacts the cleaning brush 48 so that the cleaning brush 48 brushes off the debris on the surface of the motor housing. When the motor housing is in motion, the cleaning brush 48 contacts the cleaning brush 48 so that the debris on the surface of the motor housing is brushed off. When the motor housing passes under the cleaning brush 48, the debris on the cleaning brush 48 falls into the collection box 49, so as to achieve the effect of cleaning and collecting the debris generated by drilling holes in the motor housing; a slide bar 41 is slidably installed on the operating table 1, one end of the slide bar 41 is connected to a short shaft 42, and the other end of the slide bar 41 is hinged with a push rod 43, and the four arc grooves on the slide wheel 37 contact the short shaft 42 in turn during the movement, a spring is arranged between the slide bar 41 and the slide frame 44, and a movable block 45 is slidably installed on the slide frame 44, and the movable block 45 is hinged to one end of the push rod 43 away from the slide bar 41, and a plurality of protrusions 46 are installed on the movable block 45 , the plurality of protrusions 46 contact with the cleaning brush 48 in turn during the movement, and each rotation of the groove wheel 37 can drive the slide bar 41 to perform a forward and backward reciprocating motion through the cooperation of two of the arc grooves, and the slide bar 41 drives the movable block 45 to perform an up and down reciprocating motion through the push rod 43 during the forward and backward reciprocating motion, and the movable block 45 drives the plurality of protrusions 46 to move synchronously during the movement, and the plurality of protrusions 46 contact with the cleaning brush 48 in turn during the movement, and through the cooperation between the cleaning brush 48 and the inner slide 47, the plurality of protrusions 46 can drive the cleaning brush 48 to vibrate during the movement, and the cleaning brush 48 can vibrate through the vibration It can promote the cleaning effect and also facilitate the cleaning brush 48 to shake off the debris attached to it; through the setting of the cleaning component 4, the cleaning brush 48 can clean the debris on the motor casing after the drilling of the motor casing is completed, avoiding more debris remaining on the motor casing and increasing the cleaning work of subsequent staff; through the cooperation between multiple protrusions 46 and the cleaning brush 48, the cleaning brush 48 can vibrate during cleaning, thereby promoting the cleaning effect. When the motor casing is not in contact with the cleaning brush 48, the cleaning brush 48 shakes off the debris attached to it through vibration, thereby maintaining the cleanliness of the cleaning brush 48 itself.

[0024] Further, see Figure 8 - Fig.10, a grinding assembly 5 is used to grind the warped edge on the motor housing. The grinding assembly 5 is arranged on the operating table 1. The grinding assembly 5 includes a mounting cover 51. The mounting cover 51 is slidably mounted on the inner wall of the operating table 1. The operating table 1 limits the mounting cover 51. The mounting cover 51 can move up and down slightly on the operating table 1. A third gear 54 is rotatably mounted on the operating table 1. A plum blossom wheel 55 is connected to the third gear 54. A driven roller 56 is rotatably mounted inside the mounting cover 51. A driven shaft 57 is connected to the driven roller 56. The driven shaft 57 is rotatably connected to the inner wall of the mounting cover 51. A mounting shaft 59 is rotatably mounted on the mounting cover 51. A belt 58 is sleeved on the mounting shaft 59 and the driven shaft 57. The mounting shaft 59 The bottom of the motor 50 is connected to four elastic telescopic rods 510, and the bottom of the four elastic telescopic rods 510 is connected to a grinding wheel 511. The mounting shaft 59 drives the grinding wheel 511 to rotate through the four elastic telescopic rods 510. The grinding wheel 511 uses the elastic force of the four elastic telescopic rods 510 to apply a certain pressure to the motor housing. The grinding wheel 511 can grind the warped edge on the mounting hole of the motor housing to improve the punching quality by rotating. The third gear 54 is meshed with the first gear 32. A plurality of round rods are arranged on the driven roller 56, and a plurality of paddles are arranged on the plum blossom wheel 55. The plurality of paddles on the plum blossom wheel 55 are respectively in contact with the plurality of round rods on the driven roller 56 when moving. When the plum blossom wheel 55 rotates, the plurality of paddles above it and the driven roller 5 The cooperation between the multiple round rods on 6 drives the driven roller 56 to rotate, and the friction between the multiple round rods and the multiple paddles in the vertical direction is low, so that the plum blossom wheel 55 and the driven roller 56 can maintain the transmission relationship while the driven roller 56 can also move up and down to a certain extent; the turntable 34 is equipped with an arc block 52, and the mounting cover 51 is connected with a roller 53. When the arc block 52 moves, it contacts the roller 53. When the arc block 52 is in contact with the roller 53, the roller 53 moves upward along the arc surface of the arc block 52 first, and then moves downward. When the roller 53 moves upward, it can drive the mounting cover 51 to move upward. When the roller 53 moves downward, the mounting cover 51 moves downward. When the slide wheel 37 is reset and starts to rotate, the grinding wheel 511 is lifted upward, and the motor housing under the grinding wheel 511 rotates along with the support rod 312, and the next motor housing moves to the bottom of the grinding wheel 511. When the slide wheel 37 stops rotating, the motor housing moves into place, and the grinding wheel 511 contacts the motor housing to perform a grinding operation, thereby avoiding the grinding wheel 511 from affecting the movement trajectory of the motor housing; through the setting of the grinding assembly 5, after the motor housing is punched and cleaned, the grinding wheel 511 grinds the motor housing by rotating, and grinds the warped edge generated when the motor housing is punched to be smooth, thereby improving the punching quality of the motor housing and avoiding the warped edge of the mounting hole of the motor housing that affects the subsequent installation operation;Through the cooperation of the arc block 52 and the roller 53, when the motor housing moves, the mounting cover 51 can lift the grinding wheel 511 to prevent the motor housing from colliding with the grinding wheel 511 and affecting the movement trajectory of the motor housing.

[0025] With the above structure, the working principle of this case is that the staff puts the motor housing on the two support rods 312 of the same group. After the motor housing is put on the two support rods 312, the two elastic rods 313 apply a supporting force to the inner wall of the motor housing through the elastic force of the spring, so that the two support rods 312 and the two elastic rods 313 support and fix the motor housing from the inside, thereby achieving a clamping effect. After starting the motor 31, the motor 31 drives the No. 1 gear 32 to rotate, and the No. 1 gear 32 drives the turntable 34 to rotate through the No. 2 gear 33, and the turntable 34 drives the lever 35 to rotate. During the rotation, the lever 35 will contact one of the straight grooves on the slide wheel 37, so that the lever 35 drives the slide wheel 37 to rotate through the straight groove when rotating. When the slide wheel 37 rotates to ninety degrees, the lever 35 disengages from the straight groove, and the lever 35 rotates a second circle. When the lever 35 rotates one circle, it will contact another straight groove and drive the groove wheel 37 to rotate ninety degrees. Each time the lever 35 rotates one circle, it can drive the groove wheel 37 to rotate ninety degrees through one of the straight grooves. When the groove wheel 37 rotates, it drives the rotating shaft 36 to rotate. When the rotating shaft 36 rotates, it drives the chassis 38 to rotate. When the chassis 38 rotates, it drives the four groups of support rods 312 to rotate, so that the four groups of support rods 312 can drive the motor housing to rotate ninety degrees periodically. A group of support rods 312 with the motor housing transports the motor housing to the bottom of the punching machine 2. The punching machine 2 is a prior art that can automatically perform a punching operation by presetting. After the punching machine 2 is started, the motor housing moving to the bottom thereof is punched. Since the two support rods 312 support from the inside of the motor housing, the downward pressure generated by part of the punching machine 2 when punching is offset, which greatly reduces the possibility of motor deformation.The staff can rotate the threaded rod 316 through the hand wheel 317. When the threaded rod 316 rotates, the cooperation between the thread groove and the ball bearing drives the cone block 315 to slide upward or downward on the inner wall of the cover plate 314. When the cone block 315 moves downward, the cone block 315 presses the four sliders 310 downward, so that the four inclined surfaces of the cone block 315 apply lateral thrust to the four sliders 310, so that the four sliders 310 move away from the cone block 315. When the sliders 310 move away from the cone block 315, the two The connecting rod 311 drives the two struts 312 to move away from each other, thereby increasing the distance between the two struts 312. When the frustum block 315 moves upward, due to the elastic force of the springs between the two struts 312 and two of the connecting blocks 39, the two struts 312 always maintain a force in the direction of approaching each other. The two struts 312 also apply a reverse thrust to the slider 310 through the two connecting rods 311. After the frustum block 315 moves upward, the slider 310 uses the reverse thrust generated by the two struts 312 to move along the frustum block 315. The inclined surface of 15 moves toward the direction close to the frustum block 315, and the two support rods 312 move toward each other, thereby reducing the distance between the two support rods 312. By adjusting the distance between the two support rods 312, it can adapt to motor housings with different inner diameters. The staff can adjust the distance between the two support rods 312 by turning the hand wheel 317 according to actual processing requirements to meet the support requirements and maintain the stability of the motor housing; through the setting of the support assembly 3, the two support rods 312 and the two elastic rods 313 are coordinated to support and fix the inside of the motor housing. When the two support rods 312 are rotated to transport the motor housing to the bottom of the punching machine 2 for punching, the internal support method is used to avoid deformation of the motor housing during punching as much as possible, thereby improving product quality; the staff can adjust the distance between the two support rods 312 by turning the hand wheel 317 according to the processing requirements of motors of different specifications, so that the two support rods 312 can maintain the stability of the support, thereby enhancing the applicability of the support assembly 3. ;

[0026] After the motor housing has completed the drilling operation, the motor housing moves to the bottom of the cleaning brush 48 as the turntable 34 rotates. The cleaning brush 48 is flexibly set. During the movement of the motor housing, the motor housing contacts the cleaning brush 48 so that the cleaning brush 48 brushes off the debris on the surface of the motor housing. When the motor housing passes under the cleaning brush 48, the debris on the cleaning brush 48 falls into the collection box 49, thereby achieving the effect of cleaning and collecting the debris generated by drilling the motor housing. When the chute wheel 37 stops, one of the chute wheels 37 The arc groove contacts the short shaft 42. When the slide wheel 37 starts to rotate, the arc groove drives the slide bar 41 to move away from the slide wheel 37 through the short shaft 42. When the next arc groove contacts the short shaft 42, the slide bar 41 moves toward the slide wheel 37 through the elastic force of the spring between the slide frame 44, so that the short shaft 42 keeps in contact with the arc groove. Every time the slide wheel 37 rotates, it can drive the slide bar 41 to perform a back and forth reciprocating motion through the cooperation of two of the arc grooves. During the back-and-forth reciprocating motion, the movable block 45 is driven by the push rod 43 to perform an up-and-down reciprocating motion. During the motion, the movable block 45 drives the plurality of protrusions 46 to move synchronously. The plurality of protrusions 46 contact the cleaning brush 48 in turn during the motion. Through the cooperation between the cleaning brush 48 and the inner slide 47, the plurality of protrusions 46 can drive the cleaning brush 48 to vibrate during the motion. The cleaning brush 48 can promote the cleaning effect through vibration, and it is also convenient for the cleaning brush 48 to shake off the debris attached to it. Through the arrangement of the cleaning component 4, after the motor housing is punched, the cleaning brush 48 can clean the debris on the motor housing, avoiding the residual debris on the motor housing and increasing the cleaning work of the subsequent staff. Through the cooperation between the plurality of protrusions 46 and the cleaning brush 48, the cleaning brush 48 can vibrate during cleaning, thereby promoting the cleaning effect. When the motor housing is not in contact with the cleaning brush 48, the cleaning brush 48 shakes off the debris attached to it through vibration, thereby maintaining the cleanliness of the cleaning brush 48 itself.

[0027] The motor housing that has just completed the debris cleaning moves to the bottom of the grinding wheel 511. When the No. 1 gear 32 rotates, it drives the plum blossom wheel 55 to rotate through the No. 3 gear 54. The plum blossom wheel 55 drives the driven roller 56 to rotate through the cooperation between the multiple paddles above it and the multiple round rods on the driven roller 56. Since the friction between the multiple round rods and the multiple paddles in the vertical direction is relatively low, the plum blossom wheel 55 and the driven roller 56 can maintain the transmission relationship while the driven roller 56 can also move up and down to a certain extent. When the driven roller 56 rotates, it drives the driven shaft 57 to rotate. The driven shaft 57 drives the installation shaft 59 to rotate through the belt 58. The installation shaft 59 drives the driven roller 59 through the four elastic telescopic rods 510. The grinding wheel 511 rotates, and the grinding wheel 511 uses the elastic force of the four elastic telescopic rods 510 to apply a certain pressure to the motor housing. The grinding wheel 511 can grind the warped edge on the mounting hole of the motor housing to be smooth by rotating, thereby improving the quality of drilling. When the turntable 34 rotates, the turntable 34 drives the arc block 52 to rotate synchronously. The arc block 52 contacts with the roller 53 during the rotation. Since the operating table 1 limits the mounting cover 51, the mounting cover 51 can move up and down slightly on the operating table 1. The mounting cover 51 uses its own gravity to keep the roller 53 downward. When the arc block 52 contacts with the roller 53, the roller 53 moves along the arc surface of the arc block 52. First move upward, then move downward, when the roller 53 moves upward, it can drive the mounting cover 51 to move upward, when the roller 53 moves downward, the mounting cover 51 resets downward, and when the mounting cover 51 moves, it drives the driven roller 56, the driven shaft 57, the belt 58, the mounting shaft 59, the four elastic telescopic rods 510 and the grinding wheel 511 to move synchronously, at the same time, the grinding wheel 511 still keeps rotating, so that when the groove wheel 37 starts to rotate, the grinding wheel 511 is lifted upward, and the motor housing under the grinding wheel 511 rotates with the support rod 312, and the next motor housing moves to the bottom of the grinding wheel 511, and when the groove wheel 37 stops rotating, the motor housing moves into place, and the grinding wheel 511 contacts the motor housing for grinding, thereby preventing the grinding wheel 511 from affecting the movement trajectory of the motor housing. By setting the grinding assembly 5, after the motor housing is punched and cleaned, the grinding wheel 511 grinds the motor housing by rotating, thereby smoothing the warped edges generated when the motor housing is punched, improving the drilling quality of the motor housing, and preventing the installation holes of the motor housing from having warped edges and affecting subsequent installation operations. By cooperating with the arc block 52 and the roller 53, the mounting cover 51 can lift the grinding wheel 511 when the motor housing is moving, thereby preventing the motor housing from colliding with the grinding wheel 511 when moving, thereby affecting the movement trajectory of the motor housing.

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
