The rotary drive assembly 6 is used to drive the rotor clamping mechanism 4 to rotate. The gasket pressing mechanism 7 is used to press the gasket output by the gasket discharging mechanism onto the commutator end of the rotor.

[0100] The beneficial effects of the rotor commutator polishing and gasket insertion device provided in the embodiment of the present application are: compared with the prior art, the rotor commutator polishing and gasket insertion device in the embodiment of the present application is provided with a rotor clamping mechanism 4 to clamp the rotor, a polishing belt conveying mechanism 2 and a rotating drive assembly 6 are provided to cooperate in polishing the rotor commutator, a gasket discharging mechanism 3 and a gasket pressing mechanism 7 are provided to cooperate in pressing the gasket into the commutator end of the rotor, polishing and gasket insertion use the same workstation, the processes are concentrated, the production efficiency is high, and costs are saved.

[0101] In one embodiment, see Figure 3 and Figure 7 The gasket discharging mechanism includes a gasket discharging rod 34, which is connected to the first pushing assembly 5. The first pushing assembly 5 drives the gasket discharging rod 34 to move. A gasket discharging trough 341 is provided on the gasket discharging rod 34. The gasket discharging trough 341 is used to place gaskets. The depth of the gasket discharging trough 341 is consistent with the thickness of the gasket, ensuring that the gasket discharging trough 341 only transports one gasket at a time. A guide hole 342 is provided on the bottom wall of the gasket discharging trough 341. The other end of the guide hole 342 is connected to a vacuum connector 343, and a vacuum suction device is externally connected through the vacuum connector 343. The vacuum suction device can be a vacuum pump. The guide hole 342 generates suction to firmly adsorb the gasket in the gasket discharging trough 341.

[0102] In one embodiment, see Figure 11 and Figure 12The gasket pressing mechanism 7 includes a second pushing component 71, an elastic sleeve 72 and an elastic pin 73. The elastic sleeve 72 is connected to the second pushing component 71, and the second pushing component 71 is used to drive the elastic sleeve 72 to move. A connecting groove 721 is provided on the elastic sleeve 72, and the connecting groove 721 is located on the end of the elastic sleeve 72 away from the second pushing component 71. A first spring 722 is provided in the connecting groove 721, and the elastic pin 73 is retractably installed in the connecting groove 721, and one end of the first spring 722 abuts against the elastic pin 73. The elastic pin 73 is used to insert into the inner hole of the gasket to remove the gasket. The upper end of the elastic pin 73 is in interference connection with the inner hole of the gasket, and the elastic sleeve 72 is used to press the gasket on the elastic pin 73 to the commutator end of the rotor.

[0103] When the first pushing assembly 5 drives the rotor clamping mechanism 4 to move to a position close to the polishing belt conveying mechanism 2, refer to Figure 3 The gasket discharge slot 341 corresponds to the elastic sleeve 72, and the conductive hole 342 corresponds to the elastic pin 73. At this time, when the second pushing component 71 drives the elastic sleeve 72 downward, the elastic pin 73 can be inserted into the gasket inner hole located in the gasket discharge slot 341. The positions of the elastic pin 73 and the conductive hole 342 correspond to each other, making it easier for the elastic pin 73 to be inserted into the conductive hole 342 and avoiding interference with the gasket discharge slot 341, which would cause the gasket to fail to be removed.

[0104] When the first pushing assembly 5 drives the rotor clamping mechanism 4 to move to a position close to the gasket discharging mechanism 3, refer to Figure 1 The spring pin 73 corresponds to the position of the rotor shaft. At this time, when the second pushing component 71 drives the spring sleeve 72 to press down, the gasket is sleeved on the spring pin 73, the spring pin 73 abuts the rotor shaft, and the spring pin 73 retreats into the connecting groove 721. The spring sleeve 72 presses the gasket against the commutator end of the rotor.

[0105] In one embodiment, see Figure 3 and Figure 7 The rotor commutator polishing and shim insertion device also includes a detection circuit for detecting whether a shim is present in the shim discharge slot 341. The shim discharge rod 34 and the spring pin 73 are both conductive. The detection circuit electrically connects the shim discharge rod 34 and the spring pin 73. The spring sleeve 72 is insulating. The diameter of the conductive hole 342 is larger than the diameter of the spring pin 73.

[0106] The detection circuit may include a power supply, a light bulb and a wire, wherein the wire connects the power supply, the light bulb, the gasket discharge rod 34 and the spring needle 73 in series.

[0107] When there is a gasket in the gasket discharge slot 341, the spring pin 73 is pressed down and inserted into the inner ring of the gasket, the detection circuit is connected, and the light bulb lights up. When there is no gasket in the gasket discharge slot 341, the spring pin 73 extends into the conductive hole 342, the spring sleeve 72 contacts the bottom wall of the gasket discharge slot 341, the detection circuit is disconnected, and the light bulb does not light up.

[0108] In one embodiment, see Figure 1 and Figure 12 The gasket pressing mechanism 7 also includes a guide post 74, a fixed plate 75, a connector 76, a lower pressing plate 77, a connecting seat 78 and a second spring 79. The fixed plate 75 is connected to one end of the guide post 74, and the second pushing assembly 71 is mounted on the fixed plate 75. The connector 76 is connected to the output end of the second pushing assembly 71, and the cross-section of the connector 76 is T-shaped. A connecting hole is provided on the lower pressing plate 77, and the connecting hole corresponds to the position of the guide post 74. A linear bearing 771 is provided in the connecting hole, and the linear bearing 771 is sleeved on the guide post 74. The elastic sleeve 72 is connected to the lower pressing plate 77 and is located on the side of the lower pressing plate 77 away from the second pushing assembly 71. The linear bearing 771 is provided to ensure that the lower pressing plate 77 moves more smoothly along the length direction of the guide post 74. The connecting seat 78 is connected to the lower pressing plate 77 and is located on the side of the lower pressing plate 77 away from the elastic sleeve 72. A T-slot 781 is provided on the connecting seat 78, and the connector 76 is limitedly connected in the T-slot 781. By placing a T-shaped connector 76 upside down within a T-slot 781, the second pusher assembly 71 can drive the connector 78 to move back and forth along the length of the guide post 74. A second spring 79 is positioned within the T-slot 781, with its ends abutting the connector 76 and the bottom wall of the T-slot 781, respectively. This second spring 79 acts as a buffer, preventing excessive pressure from being applied to the commutator end of the rotor during the downward movement of the spring sleeve 72, potentially damaging the product.

[0109] In one embodiment, see Figure 1 、 Figure 7 and Figure 8 The gasket discharging mechanism 3 also includes a gasket discharging cylinder 31 and a gasket shifting assembly 32.

The gasket discharging port 3111 is located at the end of the gasket discharging cylinder 31 away from the gasket shifting assembly 32. The gasket shifting assembly 32 is used to shift the gaskets in the gasket discharging cylinder 31 out of the gasket discharging port 3111. A gasket discharging rod 34 covers the gasket discharging port 3111. The gasket discharging rod 34 is used to prevent gaskets from falling out of the gasket discharging port 3111.

[0110] When the first pushing assembly 5 drives the rotor clamping mechanism 4 to move to a position close to the polishing belt conveying mechanism 2, refer to Figure 3 The gasket discharge trough 341 corresponds to the gasket discharge port 3111 , the gasket shifting assembly 32 shifts the gasket into the gasket discharge trough 341 , and the conductive hole 342 vacuums the gasket into the gasket discharge trough 341 .

[0111] In one embodiment, see Figure 7The gasket discharge mechanism 3 also includes a discharge rod guide block 33, to which the gasket discharge barrel 31 is connected. A guide groove 331 is provided on the discharge rod guide block 33, into which the gasket discharge rod 34 is slidably connected. The guide groove 331 is used to guide the gasket discharge rod 34 and also to press the gasket discharge rod 34 against the gasket discharge barrel 31, ensuring that the gasket discharge rod 34 always blocks the gasket discharge port 3111, preventing the gasket in the gasket discharge barrel 31 from falling out.

[0112] In one embodiment, see Figure 3 、 Figure 4 、 Figure 9 and Figure 10 The rotor clamping mechanism 4 includes a chuck sleeve 41, a chuck 42, and a third spring 43. A first through-hole is provided in the center of the chuck sleeve 41. The chuck 42 includes a clamping portion 421, a connecting portion 422, and a raised portion 423. The clamping portion 421 and raised portion 423 are respectively connected to the ends of the connecting portion 422, which is slidably connected within the first through-hole. The raised portion 423 can be a locking nut, facilitating assembly and disassembly and insertion of the chuck 42 into the first through-hole. The clamping portion 421 is tapered, facilitating locking of the clamping portion 421 against the first through-hole. The clamping portion 421 is provided with a receiving groove 4211 and a plurality of opening grooves 4212 at one end away from the protrusion 423. The receiving groove 4211 is used to accommodate the rotor. A second through hole 4213 is provided on the bottom wall of the receiving groove 4211. The connection between the second through hole 4213 and the receiving groove 4211 is stepped, which facilitates the placement of the rotor and prevents the rotor from falling along the second through hole 4213. The opening groove 4212 is connected to the outside of the clamping head 42 along the side wall of the receiving groove 4211 and the side wall of the second through hole 4213. The provision of the opening groove 4212 can increase the elasticity of the clamping portion 421. When the clamping portion 421 is fully extended from the first through hole, the plurality of opening grooves 4212 expand, facilitating the placement of the rotor into the receiving groove 4211. When the clamping portion 421 is partially inserted into the first through hole, the plurality of opening grooves 4212 tighten, and the clamping portion 421 clamps the rotor. A third spring 43 is mounted on the connecting portion 422, with its ends respectively contacting the collet sleeve 41 and the protrusion 423. The third spring 43 facilitates pushing the protrusion 423 away from the collet sleeve 41, ensuring that the clamping portion 421 is partially retained within the first through hole. The multiple openings 4212 tighten, allowing the clamping portion 421 to securely clamp the rotor.

[0113] In one embodiment, see Figure 3 、 Figure 4 、 Figure 9 and Figure 10A limiting groove 4221 is provided on the outer surface of the connecting portion 422 of the chuck 42.

A limiting protrusion is provided on the inner wall of the first through hole at a position corresponding to the limiting groove 4221. The limiting protrusion is slidably connected within the limiting groove 4221. The limiting protrusion can be a portion of a screw that passes through the side wall of the chuck sleeve 41 and protrudes into the first through hole. The limiting protrusion and the limiting groove 4221 are arranged to cooperate and connect to ensure that the chuck 42 can only move axially along the first through hole and cannot rotate within the first through hole. This ensures that when the rotary drive assembly 6 drives the chuck sleeve 41 to rotate, the chuck sleeve 41 also drives the chuck 42 to rotate.

[0114] In one embodiment, see Figure 1 and Figure 5 The polishing tape conveyor mechanism 2 includes a discharge motor 21, a feed tray 22, multiple first guide rollers 23, a take-up motor 24, a take-up gear 25, and a pressure gear 26.

The stops 271 are provided with a retaining groove 2711, which is arranged along the length of the polishing belt support plate 27 and is disposed opposite to each other. The two second guide pulleys 272 are connected to the polishing belt support plate 27 and are located at opposite ends of the same side of the polishing belt support plate 27 along the width direction. The slider 28 is slidably connected to the polishing belt support plate 27, with its ends along the width direction slidably connected within the two retaining grooves 2711. The retaining grooves 2711 are used to limit the movement of the slider 28 to the length direction of the polishing belt support plate 27, thereby ensuring the sliding stability of the slider 28. A counterweight 281 is connected to the slider 28, and a third guide pulley 282 is connected to the slider 28. The polishing belt is slidably connected to the two second guide pulleys 272 and the third guide pulley 282. The polishing belt passes over one second guide pulley 272, then passes over the third guide pulley 282 in the middle, and then passes over the other second guide pulley 272. The polishing belt forms a V-shaped path between the two second guide pulleys 272 and the third guide pulley 282. The counterweight 281 keeps the polishing belt taut, ensuring a good polishing effect.

[0130] Working principle of the rotor commutator polishing gasket device according to the embodiment of the present application:

[0131] In the initial state of the machine, the output end of the first cylinder extends out, the rotor clamping mechanism 4 is located near the gasket discharge mechanism 3, and the chuck 42 is placed directly below the spring pin 73 of the gasket pressing mechanism 7. At this time, the gasket discharge groove 341 corresponds to the position of the gasket discharge port 3111.

[0132] The output end of the third cylinder is pushed upward, pushing the chuck 42 to move along the first through hole of the chuck sleeve 41. The clamping portion 421 is in a loose state, and the multiple open slots 4212 on the clamping portion 421 are expanded. The output end of the second cylinder is not pushed out, and the spring pin 73 is above the clamping portion 421. The belt discharge motor 21 and the belt take-up motor 24 of the polishing belt conveyor mechanism are not rotating. The gasket shifting motor 321 of the gasket discharge mechanism 3 is continuously rotating, shifting the gasket in the gasket discharge cylinder 31. The guide hole 342 of the gasket discharge rod 34 is vacuum-sucked, and the rotation motor 61 of the rotary drive assembly 6 is continuously rotating.

[0133] Place the rotor into the accommodating groove 4211 of the chuck 42 with the rotor commutator facing upward, press the inching switch 12, the output end of the third cylinder retracts downward, the third spring 43 pushes the protrusion 423 away from the chuck sleeve 41, a part of the clamping part 421 extends into the first through hole, the opening groove 4212 of the clamping part 421 is tightened, and the clamping part 421 clamps the rotor.

[0134] The output end of the first cylinder retracts, and the rotor clamping mechanism 4 is positioned near the polishing belt conveyor mechanism 2. One end of the rotor clamping mechanism 4 extends into the polishing groove 291. The driving wheel 62 of the rotating mechanism abuts the chuck sleeve 41, driving the driving wheel 62 to rotate the chuck sleeve 41, and the polishing belt is pressed against the surface of the rotor commutator. Simultaneously, the belt discharge motor 21 and the belt take-up motor 24 rotate, driving the polishing belt to move and polish. At this time, the gasket is also discharged by the gasket discharge rod 34.

[0135] The output end of the second cylinder pushes downward. When a gasket is present in the gasket discharge slot 341 of the gasket discharge rod 34, the spring pin 73 inserts into the gasket inner hole, and the detection circuit is turned on. When no gasket is present in the gasket discharge slot 341 of the gasket discharge rod 34, the spring pin 73 inserts into the gasket inner hole, and the detection circuit is turned off. The output end of the first push cylinder pushes the rotor clamping mechanism 4 to a position close to the gasket discharge mechanism 3, aligning the gasket discharge slot 341 with the gasket discharge port 3111. The gasket discharge rod 34 then repeats the gasket removal operation. The output end of the first push cylinder retracts, driving the rotor clamping mechanism 4 to a position close to the polishing belt conveyor 2, and repeating the gasket detection until the detection circuit is turned on.

[0136] The output end of the second cylinder retracts upward, completing the gasket removal operation. The output end of the first cylinder pushes the rotor clamping mechanism 4 close to the gasket discharge mechanism 3, and the chuck 42 reaches directly below the spring pin 73 of the gasket pressing mechanism 7. The brake block 161 of the brake mechanism rubs against the chuck sleeve 41, causing the chuck sleeve 41 to stop rotating.

[0137] The output end of the second cylinder pushes downward, pushing the gasket on the spring pin 73 into the shaft at the rotor commutator end. The spring pin 73 retreats into the connecting groove 721, and the spring sleeve 72 presses the gasket tightly. Then the output end of the second cylinder retreats upward, completing the gasket pressing action.

[0138] The output end of the third cylinder is pushed upward, pushing the chuck 42 to move along the first through hole of the chuck sleeve 41. The clamping part 421 is in a loose state, and the multiple open grooves 4212 on the clamping part 421 are unfolded. The polished and gasketed rotor is taken away, and the rotor to be processed is placed in the accommodating groove 4211, and the above actions are repeated.

[0139] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
