Description

Technical Field

[0001] This invention relates to the technical field of motor assembly machines, and in particular to a brush box and carbon brush holder assembly device. Background Technology

[0002] The electric motor is an important functional component of a car, mainly consisting of a stator, rotor, brush holder, carbon brushes, and commutator. Mechanical commutation is achieved through the interaction of the carbon brushes and the commutator. The brush holder is used for positioning and guiding the carbon brushes, which are mounted on the brush holder via brush boxes.

[0003] Currently, in the field of motor assembly, existing technology generally involves workers manually installing the brush box onto the carbon brush holder. This is labor-intensive, inefficient, and the connection between the brush box and the carbon brush holder is difficult to guarantee, thus affecting motor performance. Summary of the Invention

[0004] The purpose of this invention is to provide a brush box and carbon brush holder assembly device to solve the technical problems of low brush box installation efficiency and high assembly labor intensity in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A brush box and carbon brush holder assembly device is provided, comprising: a feeding device for providing a brush box, the brush box including a box body having a base plate and two support legs respectively formed at opposite ends of the base plate, the support legs extending outward from the ends of the base plate along the length direction of the base plate; a pre-bending device for receiving the brush box provided by the feeding device and bending the two support legs downward relative to the base plate, the pre-bending device being disposed on one side of the feeding device; and a receiving device disposed on one side of the pre-bending device, the receiving device including a receiving seat, the receiving seat having a function for bending the support legs downward. The device includes at least one placement slot for inserting the folded brush holder; a feeding device for providing a carbon brush holder; a secondary bending device disposed between the receiving device and the feeding device, the secondary bending device including a bending support for supporting the carbon brush holder provided by the feeding device and a secondary bending mechanism for placing the brush holder on the receiving device on the bending support and bending the two legs of the brush holder inward relative to the base plate, the secondary bending mechanism being vertically and vertically disposed above the bending support and reciprocating between the bending support and the receiving device; and a pressing device disposed on one side of the secondary bending device for pressing the legs against the carbon brush holder.

[0006] Compared with existing technologies, the brush box and carbon brush holder assembly equipment provided by this invention includes a feeding device, a pre-bending device, a receiving device, a loading device, a secondary bending device, and a pressing device. The pre-bending device receives the brush box provided by the feeding device and bends the two legs downward relative to the base plate. The carbon brush holder provided by the loading device is supported by the bending support seat of the secondary bending device. The secondary bending device places the brush box on the receiving seat onto the bending support seat and bends the two legs of the brush box inward relative to the base plate. Then, the pressing device presses the legs tightly against the carbon brush holder. In this way, the bending and pressing of the brush box legs can be realized, thereby installing the brush box on the carbon brush holder. This not only greatly improves the assembly of the brush box on the carbon brush holder, but also increases the assembly efficiency of both and reduces production costs. Attached Figure Description

[0014] like Figure 1 and Figure 2As shown, this embodiment provides a brush box and carbon brush holder assembly device 1000, comprising: a feeding device 1001 for providing a brush box 60, the brush box 60 including a box body 61 having a base plate 62 and two support legs 63 respectively formed at opposite ends of the base plate 62, the support legs 63 extending outward from the ends of the base plate 62 along the length direction of the base plate 62; a pre-bending device 10 for receiving the brush box 60 provided by the feeding device 1001 and bending the two support legs 63 downward relative to the base plate 62, the pre-bending device 10 being disposed on one side of the feeding device 1001; and a receiving device 20 disposed on one side of the pre-bending device 10, the receiving device 20 including a receiving seat 21, the receiving seat 21 having the brush box after the support legs 63 are bent downward. At least one mounting slot 211 into which the carbon brush holder 70 is inserted; a feeding device 30 for providing the carbon brush holder 70; a secondary bending device 40 disposed between the receiving device 20 and the feeding device 30, the secondary bending device 40 including a bending support 41 for supporting the carbon brush holder 70 provided by the feeding device 30 and a secondary bending mechanism 42 for placing the brush box 60 on the receiving device 21 on the bending support 41 and bending the two legs 63 of the brush box 60 inward relative to the base plate 62, the secondary bending mechanism 42 being vertically and vertically disposed above the bending support 41 and reciprocating between the bending support 41 and the receiving device 21; and a pressing device 50 disposed on one side of the secondary bending device 40 for pressing the legs 63 against the carbon brush holder 70.

[0015] The aforementioned brush box and carbon brush holder assembly equipment 1000 includes a feeding device 1001, a pre-bending device 10, a receiving device 20, a feeding device 30, a secondary bending device 40, and a pressing device 50. The pre-bending device 10 receives the brush box 60 provided by the feeding device 1001 and bends its two legs 63 downwards relative to the base plate 62. The secondary bending device 40 supports the carbon brush holder 70 provided by the feeding device 30 via a bending support seat 41. The secondary bending device 40 places the brush box 60 on the receiving seat 21 into the bending support seat 50. The two legs 63 of the brush box 60 are bent inward relative to the base plate 62 on the bent support base 41, and then the clamping device 50 presses the legs 63 against the carbon brush holder 70. In this way, the bending and clamping of the legs 63 of the brush box 60 can be realized, thereby installing the brush box 60 on the carbon brush holder 70. This not only greatly improves the assembly of the brush box 60 on the carbon brush holder 70, increases the assembly efficiency of the two, and reduces production costs, but also makes the connection between the brush box 60 and the carbon brush holder 70 more stable and reliable, ensuring the performance of the motor.

[0016] See Figure 1 and Figure 2 The brush box and carbon brush holder assembly equipment 1000 provided in this embodiment includes a feeding device 1001, a pre-bending device 10, a receiving device 20, a feeding device 30, a secondary bending device 40, and a pressing device 50.

[0017] See Figures 1 to 4 , Figure 6 The feeding device 1001 provided in this embodiment is used to provide brush boxes 60. The brush box 60 includes a box body 61 with a base plate 62 and two support legs 63 respectively formed at opposite ends of the base plate 62. The support legs 63 extend outward from the ends of the base plate 62 along the length direction of the base plate 62. In this embodiment, the feeding device 1001 includes a vibrating plate part, which can provide the brush boxes 60 one by one to the pre-bending device 10. The brush box 60 includes a rectangular box body 61 for mounting carbon brushes (not shown). The box body 61 has a base plate 62. The carbon brushes can move along the length direction of the base plate 62 of the brush box 60. The support legs 63 are arranged horizontally outward from both ends of the base plate 62 along the length direction of the base plate 62. The vibrating plate part moves the brush box 60 toward the pre-bending device 10 with one side of the base plate 62 facing down.

[0018] See Figures 1 to 15 The pre-bending device 10 provided in this embodiment is used to receive the brush box 60 provided by the feeding device 1001 and bend the two legs 63 downward relative to the base plate 62 respectively, so that the included angle between the legs 63 and the base plate 62 is, but not limited to, 90 degrees. The pre-bending device 10 is located on one side of the feeding device 1001.

[0019] See Figures 4 to 15 The pre-bending device 10 provided in this embodiment includes a conveyor seat 11, a pre-bending mechanism 12, and two bending support assemblies 13.

[0020] See Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 14 and Figure 15The conveyor seat 11 provided in this embodiment has a first side 11a, a second side 11b opposite to the first side 11a, and a conveying channel 111 extending along the length direction of the conveyor seat 11 and for the brush box 60 to move. The conveying channel 111 has two opposing longitudinal walls 1111. Each longitudinal wall 1111 has a horizontal groove 112 for inserting the support leg 63 of the brush box 60 and extending along the length direction. The bottom surface of the conveying channel 111 has a vertical groove 113 for inserting the downwardly bent support leg 63 of the brush box 60 and extending along the length direction. The conveyor seat 11 has an inlet position 114, a first bending position 115, and a second bending position 116 arranged sequentially along the length direction to connect with the outlet of the feeding device 1001. In this embodiment, the conveyor seat 11 connects with the outlet of the vibrating plate part. The conveying seat 11 is, but is not limited to, a rectangular seat. The first side 11a and the second side 11b of the conveying seat 11 are arranged opposite each other in a direction perpendicular to the length direction. The conveying channel 111 is formed on the top surface of the conveying seat 11 and extends along the entire length of the conveying seat 11. The bottom of each longitudinal wall 1111 is provided with a horizontal groove 112 for the support leg 63 of the brush box 60 to be bent provided by the feeding device 1001 to be inserted and moved, and extends along the length direction of the conveying seat 11 (i.e., the direction of movement of the brush box 60 on the seat). The bottom surface of the conveying channel 111 is provided with a vertical groove 113 for the support leg 63 of the brush box 60 after bending downward to be inserted and moved, and extends along the length direction of the conveying seat 11. There are two vertical grooves 113, which correspond to the two horizontal grooves 112 respectively.

[0021] See Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 15The pre-bending mechanism 12 provided in this embodiment is used to bend the support leg 63 in the horizontal groove 112 into the vertical groove 113. The pre-bending mechanism 12 includes a first pre-bending assembly 121 disposed on the first side 11a and used to press the support leg 63 of the brush box 60 located in the first bending position 115, a second pre-bending assembly 122 disposed on the second side 11b and used to press the support leg 63 of the brush box 60 located in the second bending position 116, and a pre-bending lifting power 123 for driving the first pre-bending assembly 121 and the second pre-bending assembly 122 to rise and fall. Two bending support assemblies 13 are used to hold the brush box 60 on the conveying channel 111 during bending. One of the two bending support assemblies 13 is disposed on the second side 11b and corresponds to the first pre-bending assembly 121, and the other is disposed on the first side 11a and corresponds to the second pre-bending assembly 122. A first pre-bending slot 117 corresponding to the first pre-bending assembly 121 is provided on the first side 11a of the conveyor seat 11. The first pre-bending slot 117 connects to the conveying channel 111 and extends from the top of the conveyor seat 11 to the bottom of the conveyor seat 11. A second pre-bending slot 118 corresponding to the second pre-bending assembly 122 is provided on the second side 11b of the conveyor seat 11. The second pre-bending slot 118 connects to the conveying channel 111 and extends from the top of the conveyor seat 11 to the bottom of the conveyor seat 11. It is understood that the first pre-bending slot 117 and the second pre-bending slot 118 are located on opposite sides of the conveyor seat 11. The first pre-bending slot 117 connects the conveyor channel 111 and the horizontal slot 112 and vertical slot 113 near the first side 11a. The second pre-bending slot 118 connects the conveyor channel 111 and the horizontal slot 112 and vertical slot 113 near the second side 11b. The first pre-bending assembly 121 is installed at the first pre-bending slot 117 of the conveyor seat 11, corresponding to the first bending position 115. The second pre-bending assembly 122 is installed at the second pre-bending slot 118 of the conveyor seat 11, corresponding to the second bending position 116. The brush box 60 in the first bending position 115 is close to the support leg 6 of the first side 11a. 3. Suspended in the first pre-bending slot 117, the support leg 63 of the brush box 60 located in the first bending position 115 near the first side 11a can be bent downward by the action of the first pre-bending assembly 121 and the pre-bending lifting power 123, so that the support leg 63 is basically perpendicular to the box body 61. The support leg 63 of the brush box 60 located in the second bending position 116 near the second side 11b is suspended in the second pre-bending slot 118. The support leg 63 of the brush box 60 located in the second bending position 116 near the second side 11b can be bent downward by the action of the second pre-bending assembly 122 and the pre-bending lifting power 123, so that the support leg 63 is basically perpendicular to the box body 61, thereby realizing the downward bending of the two support legs 63 of the brush box 60 respectively.

[0022] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 15 The first pre-bending component 121 and the second pre-bending component 122 provided in this embodiment may have the same structure or different structure.

[0023] In this embodiment, the pre-bending mechanism 12 includes a pre-bending base plate 124 located below the conveyor seat 11 and connected to the pre-bending lifting power 123. The first pre-bending assembly 121 and the second pre-bending assembly 122 are mounted on the pre-bending base plate 124. The first pre-bending assembly 121 and the second pre-bending assembly 122 have the same structure. Both the first pre-bending assembly 121 and the second pre-bending assembly 122 include a pre-bending fixing seat 1211 fixed on the pre-bending base plate 124 and connected to the pre-bending lifting power 123 through the pre-bending base plate 124, a pre-bending translational seat 1212 movably mounted on the pre-bending fixing seat 1211 in a direction perpendicular to the length direction of the conveyor seat 11, a pre-bending pressing block 1213 mounted on the top of the pre-bending translational seat 1212 and used to press the support leg 63 downward, and a pre-bending translational force member 1214 fixed on the pre-bending fixing seat 1211 and used to drive the pre-bending translational seat 1212 to move. The pre-bending top pressure block 1213 of the first pre-bending assembly 121 is movably disposed in the first pre-bending slot 117, and the pre-bending top pressure block 1213 of the second pre-bending assembly 122 is movably disposed in the second pre-bending slot 118. It is easy to understand that after the pre-bending top pressure block 1213 moves above the support leg 63, as the pre-bending lifting power 123 drives the pre-bending base plate 124 to move down (lower part of the figure), the pre-bending top pressure block 1213 presses the support leg 63 downward (lower part of the figure), and the pre-bending translational force member 1214 drives the pre-bending translational seat 1212 and the pre-bending top pressure block 1213 to move in the direction of the conveying channel 111, thereby bending the support leg 63 downward and inward.

[0024] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 15The bending support assembly 13 provided in this embodiment includes a bending support fixed seat 131 fixed on the conveying seat 11, a bending support translation seat 132 movably mounted on the bending support fixed seat 131 in a direction perpendicular to the length direction, a bending support rod 133 mounted on the bending support translation seat 132 and used to insert the box body 61 of the brush box 60, and a bending support translation force member 134 fixed on the bending support fixed seat 131 and used to drive the bending support translation seat 132 to move; the conveying seat 11 is provided with a support through groove 119 for the bending support rod 133 to move, and the support through groove 119 connects the conveying channel 111 and the horizontal groove 112. In this embodiment, the bending support assembly 13 is used to support the brush box 60 when it is bent. The bending support assembly 13 is installed on the side of the conveyor seat 11 opposite to the first pre-bending assembly 121 and the second pre-bending assembly 122. The bending support rod 133 has a shape that matches the box body 61. Thus, before bending, the bending support translation force member 134 drives the bending support translation seat 132 and the bending support rod 133 to move, so that the end of the bending support rod 133 is inserted into the box body 61, thereby maintaining the position of the box body 61 and improving the strength of lifting the box during bending, thus preventing the box body 61 from deforming.

[0025] See Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 13 and Figure 14 The pre-bending device 10 provided in this embodiment also includes a material-pushing assembly 14, which is supported on one side of the conveyor seat 11. The material-pushing assembly 14 includes a material-pushing bracket 141 disposed above the conveyor seat 11, a material-pushing lifting power component 142 connected to the material-pushing bracket 141 and used to drive the material-pushing bracket 141 to rise and fall, and a material-pushing translational force component 143 connected to the material-pushing lifting power component 142 and used to drive the material-pushing lifting power component 142 to move along the length direction of the conveyor seat 11. The material-pushing bracket 141 includes three material-pushing column portions 1411 that can move into and out of the conveying channel 111 and are arranged side by side along the length direction of the conveyor seat 11. Corresponding to the feeding position 114, the first bending position 115, and the second bending position 116 respectively, the bottom end of the feeding column 1411 is formed with a feeding hole 1412 for inserting the box body 61. In this way, the feeding lifting power component 142 drives the feeding bracket 141 to move down, and the feeding column 1411 moves down and inserts the brush box 60 on the conveying channel 111 into the feeding hole 1412. Then, the feeding translational force component 143 can realize the movement of the brush box 60 in the conveying channel 111. It is worth mentioning that after the feeding column 1411 is fitted onto the brush box 60, the brush box 60 can be accurately positioned in the conveying channel 111, thereby improving the bending and forming accuracy.

[0026] See Figure 11 , Figure 12 and Figure 15 The pre-bending device 10 provided in this embodiment also includes a lifting assembly 15 for lifting the brush box 60 removed from the feeding device 1001 into the conveying channel 111. The lifting assembly 15 includes a lifting bracket 151 that is vertically and elliptically disposed at the inlet position 114 and a lifting power component 152 connected to the lifting bracket 151 and used to drive the lifting bracket 151 to rise and fall. The lifting bracket 151 has a receiving hole 1511 for inserting the brush box 60 removed from the feeding device 1001. In this way, a height difference is formed between the conveying channel 111 and the outlet of the feeding device 1001, which can ensure the quantity of each feeding. After the new brush box 60 is lifted by the lifting assembly 15, the brush box 60 is then moved on the conveying channel 111 by the feeding component 14.

[0027] See Figure 4 , Figure 9 , Figure 10 , Figures 16 to 18 The receiving device 20 provided in this embodiment is disposed on one side of the pre-bending device 10. The receiving device 20 includes a receiving seat 21, which has a placement groove 211 for inserting the brush box 60 after the support leg 63 is bent downwards. In this embodiment, the receiving device 20 also includes a receiving support frame 22. The receiving seat 21 is rotatably supported on the receiving support frame 22. The receiving support frame 22 is provided with a receiving rotation power component 23 connected to the receiving seat 21 and used to drive the receiving seat 21 to rotate. The receiving seat 21 has a circular cross-section and has a placement groove 211 for inserting the brush box 60 after the support leg 63 is bent downwards in a translational manner. The number of placement grooves 211 is, but not limited to, three, and the three placement grooves 211 are spaced apart circumferentially. The mounting groove 211 is formed on the top surface of the receiving seat 21 and extends from the middle of the top surface of the receiving seat 21 to the periphery of the top surface. The mounting groove 211 includes an upper mounting groove 2111 into which the body 61 of the brush box 60 is placed and a lower mounting groove 2112 located below the upper mounting groove 2111 into which the support leg 63 of the brush box 60 is placed. The width of the lower mounting groove 2112 is smaller than the width of the upper mounting groove 2111. In this way, the bottom surface of the body 61 of the brush box 60 abuts against the bottom surface of the upper mounting groove 2111 to be supported in the upper mounting groove 2111.

[0028] See Figure 4 , Figure 9 , Figure 10 and Figure 16In this embodiment, the pre-bending device 10 further includes a transfer seat 16 and a pushing assembly 17 connected to the end of the conveyor seat 11 away from the feeding device 1001. The transfer seat 16 includes a transfer groove 161 for the brush box 60 to move and communicate with the conveying channel 111. The transfer groove 161 includes an upper transfer groove 1611 for the body 61 of the brush box 60 to be placed in and a lower transfer groove 1612 located below the upper transfer groove 1611 for the support leg 63 of the brush box 60 to be placed in. The bottom surface of the body 61 of the brush box 60 abuts against the bottom surface of the upper transfer groove 1611 to be supported in the upper transfer groove 1611. The pushing assembly 17 includes a pushing rod 171 for pushing the brush box 60 in the transfer slot 161 into the placement slot 211 of the receiving seat 21, and a pushing power component 172 fixed on the transfer seat 16 for driving the pushing rod 171 to move along the length direction of the pushing rod 171. The pushing rod 171 is movably disposed in the transfer slot 1611, and the cross-sectional area of ​​the pushing rod 171 is larger than the cross-sectional area of ​​the box 61. It can be understood that after the brush box 60 with the two side legs 63 bent downwards is moved from the conveying channel 111 into the transfer slot 161 of the transfer seat 16, the receiving seat 21 is driven to rotate by the receiving rotation power component 23 to align the placement slot 211 with the transfer slot 161, and then the pushing power component 172 drives the pushing rod 171 to push the brush box 60 into the placement slot 211.

[0029] See Figure 16 and Figure 17 The feeding device 30 provided in this embodiment is used to provide a carbon brush holder 70. The feeding device 30 includes a rotary seat 31 and a rotary power component 32 connected to the rotary seat 31 and capable of driving the rotary seat 31 to rotate. The rotary seat 31 is provided with a gripper cylinder 33 at both ends for gripping the carbon brush holder 70. The carbon brush holder 70 has a horizontal through groove 71 for installing the brush box 60.

[0030] See Figures 16 to 18The secondary bending device 40 provided in this embodiment is disposed between the receiving device 20 and the feeding device 30. The secondary bending device 40 includes a bending support 41 and a secondary bending mechanism 42 that can move relative to each other in an opening and closing direction (vertical direction in the figure). The bending support 41 is used to place and support the carbon brush holder 70 provided by the feeding device 30. The secondary bending mechanism 42 is used to grab the brush box 60 on the receiving seat 21 and place the brush box 60 on the carbon brush holder 70 located on the bending support 41, and bend the two legs 63 of the brush box 60 inward relative to the bottom plate 62 respectively. The secondary bending mechanism 42 is vertically and vertically disposed above the bending support 41 and can reciprocate between the bending support 41 and the receiving seat 21. Understandably, after the secondary bending mechanism 42 moves above the receiving seat 21, it descends and grabs the brush box 60 located on the receiving seat 21, and then moves the brush box 60 above the bending support seat 41. The secondary bending mechanism 42 drives the brush box 60 to move down, thereby installing each brush box 60 at the corresponding horizontal through slot 71 on the carbon brush holder 70. As the secondary bending mechanism 42 continues to move down, together with the bending support seat 41, it further bends the support legs 63 of each brush box 60 inward, so that the support legs 63 and the base plate 62 form an angle of approximately 45 degrees.

[0031] See Figures 16 to 18 In this embodiment, the secondary bending device 40 further includes a secondary bending bracket 43, a secondary bending moving seat 44 movably disposed on the secondary bending bracket 43, a secondary bending translation driving force member 45 mounted on the secondary bending bracket 43 and used to drive the secondary bending moving seat 44 to move, a secondary bending lifting seat 46 movably disposed on the secondary bending moving seat 44, and a secondary bending lifting power member 47 used to drive the secondary bending lifting seat 46 to rise and fall.

[0032] See Figures 16 to 18In this embodiment, the secondary bending mechanism 42 includes an assembly base 421, a pressure base 422, and a retaining assembly 423. The assembly base 421 is fixedly connected to the secondary bending lifting base 46. The pressure base 422 has a circular cross-section and is used to dock with the receiving base 21. The number of retaining assemblies 423 is not limited to three. They are fixed on the assembly base 421 circumferentially and correspond to the three placement slots 211 respectively. The retaining assembly 423 includes a retaining fixing base 4231 fixed on the assembly base 421, a retaining translational base 4232 movably mounted on the retaining fixing base 4231, a retaining rod 4233 mounted on the retaining translational base 4232 and used to insert the box body 61 of the brush box 60, and a retaining translational force member 4234 fixed on the retaining fixing base 4231 and used to drive the retaining translational base 4232 to move. It should be noted that the receiving seat 21 is used to position the three brush boxes 60. The three placement slots 211 on the receiving seat 21, the three holding components 423 on the secondary bending mechanism 42, and the three horizontal through slots 71 of the carbon brush holder 70 placed on the bending support seat 41 are respectively aligned and set one by one. In this way, the assembly efficiency of each brush holder can be improved and the positional accuracy after assembly is high.

[0033] See Figure 17 and Figure 18 In this embodiment, the bending support base 41 includes a bending base 411, a first floating bracket 412 elastically connected to the bending base 411, and a bending forming block 413 fixed to the bending base 411. The number of bending forming blocks 413 is not limited to three, corresponding to the three holding components 423 and the brush box 60 respectively. The first floating bracket 412 is provided with a first contour groove 4121 that matches the shape of the carbon brush holder 70. The first floating bracket 412 has a first mounting groove 4122 for the bending forming block 413 to be inserted. The bending forming block 413 includes a bending fixing part 4131 fixed on the bending base 411 and two bending protrusions 4132 formed on the bending fixing part 4131 and arranged side by side with intervals between them. The two bending protrusions 4132 correspond to the two legs 63 of the brush box 60 respectively. Each bending protrusion 4132 includes a bending forming inclined surface 4133 for abutting against the bottom end of the leg 63. The bending forming inclined surface 4133 extends downward from the top surface of the bending protrusion 4132 and inclined toward the other bending protrusion 4132 to the bending fixing part 4131. Understandably, after the retaining component 423 presses down the brush box 60, the bottom end of the support leg 63 contacts the bending forming slope 4133 of the bending protrusion 4132, and under the guidance of the bending forming slope 4133, the support leg 63 bends inward, the support leg 63 is tilted relative to the base plate 62, and the brush box 60 is snapped onto the carbon brush holder 70.

[0034] See Figure 17In this embodiment, the first floating support 412 is provided with a circumferential positioning post for positioning the carbon brush holder 70, which is used to position the placed carbon brush holder 70.

[0035] See Figure 19 and Figure 20 In this embodiment, the pressing device 50 includes a pressing support 51 and a pressing mechanism 52 that can move relative to the pressing support 51 in the vertical direction (the vertical direction shown in the figure). The pressing mechanism 52 is movably arranged above the pressing support 51. The structure of the pressing mechanism 52 is basically the same as that of the secondary bending mechanism 42, so it will not be described again.

[0036] See Figure 19 and Figure 20 In this embodiment, the clamping support 51 includes a clamping base 511, a second floating bracket 512 elastically connected to the clamping base 511, and a clamping forming block 513 fixed to the clamping base 511. The number of clamping forming blocks 513 is, but not limited to, three. The second floating bracket 512 is provided with a second contour groove 5121 that matches the shape of the carbon brush holder 70. The second floating bracket 512 has a second mounting groove 5122 for the bending forming block 413 to be inserted. The clamping forming block 513 includes a clamping fixing part 5131 fixed to the clamping base 511 and two clamping protrusions 5132 formed on the clamping fixing part 5131 and arranged side by side and spaced apart from each other. The two clamping protrusions 5132 correspond to the two legs 63 of the brush box 60 respectively. Each clamping protrusion 5132 includes a clamping plane 5133 located on its top surface and used to abut against the bottom end of the leg 63. Understandably, an external robotic arm (not shown) grips the interlocking carbon brush holder 70 and brush box 60 on the bending support 41 together onto the second contour groove 5121 of the clamping support 51. The clamping mechanism 52 further presses down the support leg 63 of the brush box 60. Under the action of the clamping protrusion 5132, the support leg 63 continues to bend towards the bottom plate 62, and the clamping plane 5133 makes the support leg 63 stick to the bottom surface of the carbon brush holder 70, thereby fixing the brush box 60 and the carbon brush holder 70 together.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
