[0019] Beneficial effects of the present invention:

[0020] 1. The present invention can place and fix multiple bridge housings through the setting of the placement unit, and at the same time, the bridge housings of the electric drive bridge can be rotated and replaced in turn through the rotation of the placement unit, so that it can perform continuous operation. The setting of the outer ring grinding unit can perform targeted grinding operations on the outer edge of the center of the bridge housing, and the aperture grinding unit provided on one side of the outer ring grinding unit can grind the outer edge of the center of the bridge housing while the outer ring grinding unit is grinding the outer edge of the center of the bridge housing.

[0021] 2. The present invention drives the transposition shaft to rotate by turning on the motor, and the rotation of the transposition shaft synchronously drives the rotation of the transposition plate. When the transposition plate rotates, the outer ring grinding unit and the paint spraying unit can be quickly switched, and then the center of the bridge housing can be quickly polished and the inside and outside can be painted, thereby realizing the continuous grinding and painting of the bridge housing. Compared with the existing external processing device for the electric drive bridge housing, the present invention can synchronously grind the outer edge and inner wall of the middle circular ring of the bridge housing, effectively overcoming the problem of difficult grinding in the middle of the electric drive bridge. At the same time, the outer ring grinding unit and the paint spraying unit can be quickly and conveniently switched, so that after the circular ring in the middle of the bridge housing is polished, the outside of the bridge housing can be sprayed with paint.

[0022] 3. The present invention drives the sliding frame to slide in the rectangular slide groove by opening the electric slider until the outer plate is fitted with the outer edge of the circular ring in the middle of the bridge housing. At this time, the outer plate moves up in contact with the bridge housing, and then the outer plate is opened to grind the burrs on the outside of the bridge housing. When the outer plate moves up, the movable plug is simultaneously driven to move up. When the movable plug moves up, the blockage of the central tube is cancelled. At this time, the coolant in the cooling box flows through the central tube to the outer plate, and finally the coolant flows to the contact surface between the outer plate and the bridge housing. Through the setting of the coolant, not only can the outer plate be cooled when grinding the outside of the bridge housing, but also the dust generated during grinding can be washed away.

[0023] 4. The present invention drives the regulating block to slide in the side groove when the steering plate rotates. At this time, the mounting plate is flipped on the cross bar until the support box and the middle of the bridge housing are on the same axis. Then, the slider is driven to open and drive the support box to move into the center hole of the bridge housing. Then, the electric push rod is controlled to push forward. When the electric push rod is pushed forward, it simultaneously drives multiple pushing plates to expand outward. At this time, multiple grinding plates are expanded at the circular hole in the center of the bridge housing until they conflict with the center of the bridge housing. Then, the motor is turned on to drive the storage box to rotate. While the storage box rotates, it drives multiple grinding plates to perform rotational grinding in the circular ring in the center of the bridge housing, thereby realizing the grinding operation of the circular hole in the middle of the bridge housing.

[0024] 5. The present invention starts the motor to drive the driving rod to rotate, and when the driving rod rotates, the driving wheel drives the surrounding ring to rotate. When the surrounding ring rotates, the nozzle is turned on to spray paint the inner and outer walls of the circular hole in the middle of the bridge housing at the same time, and the paint in the paint spray box can be continuously transmitted and supplied to the nozzle through the setting of the transmission pipe.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] As attached Figure 1-11As shown, an external processing device of an electric drive bridge includes a base 1, a recycling box 8 is placed in the middle of the upper end surface of the base 1, and a support plate 2 fixedly connected to the base 1 is provided on the rear side of the recycling box 8. A rectangular slide is provided on the upper part of the support plate 2 close to the recycling box 8. A sliding frame 4 is slidably installed in the rectangular slide through an electric slider. Two symmetrically arranged transposition shafts 41 are installed in the middle of the sliding frame 4 through motor rotation.

An aperture grinding unit is fixedly installed on the outside of the outer ring grinding unit, and placement units are symmetrically installed on both sides of the middle of the support plate 2.

[0041] As attached Figure 3 As shown, the placement unit is set up to place and fix multiple bridge shells, and at the same time, the bridge shells of the electric drive bridge can be rotated and transposed in turn through the rotation of the placement unit, so that it can perform continuous operation. The setting of the outer ring grinding unit can perform targeted grinding operations on the outer edge of the center of the bridge shell, and the aperture grinding unit provided on one side of the outer ring grinding unit can grind the outer edge of the center of the bridge shell while the outer ring grinding unit is grinding the outer edge of the center of the bridge shell. The aperture grinding unit can also cooperate with it to grind the inside of the circular ring in the middle of the bridge shell, which effectively solves the problem of difficulty in grinding the outer edge and inner wall of the center of the bridge shell. The motor is turned on to drive the transposition shaft 41 to rotate. When the transposition shaft 41 rotates The shift plate 42 is driven to rotate synchronously. When the shift plate 42 rotates, the outer ring grinding unit and the painting unit can be quickly switched, and then the inside and outside of the bridge housing can be quickly painted after the grinding operation at the center of the bridge housing, thereby realizing the continuity of grinding and painting of the bridge housing. Compared with the existing external processing device for the electric drive bridge housing, the present invention can synchronously grind the outer edge and inner wall of the middle circular ring of the bridge housing, effectively overcoming the problem of difficult grinding in the middle of the electric drive bridge. At the same time, the outer ring grinding unit and the painting unit can be quickly and conveniently switched, so that after the grinding of the middle circular ring of the bridge housing is completed, the painting operation of the outside of the bridge housing can be carried out immediately.

[0042] The placement unit includes two symmetrically arranged telescopic plates 3, and the telescopic ends of the telescopic plates 3 are fixedly installed with side plates 30. The two side plates 30 are close to each other and a rotating frame 31 is installed on the side rotated by a motor. Multiple groups of control plates 32 are circumferentially installed on the outer edges of the rotating frames 31 on both sides. Each group of control plates 32 is jointly installed with a group of corresponding limit plates 33, and a rubber block is provided on the inner side of the limit plate 33 to fix the inner wall of the bridge housing.

[0043] By opening the two telescopic plates 3 and bringing them closer to each other, the side plates 30 can contact the two side walls of the electric drive bridge when they are close to each other, and the rubber blocks on the two side plates 30 are placed inside the bridge housing to prevent the electric drive bridge housing from sliding during grinding.

[0044] As attached Figure 5 As shown, the outer ring grinding unit includes a cooling box 5, with external frames 51 fixedly installed on both sides of the outside of the cooling box 5, an external box 52 located below the cooling box 5 is commonly installed between the two external frames 51, and a center tube 53 is commonly installed between the external box 52 and the cooling box 5, an arc-shaped groove is provided in the middle of the external box 52, and an arc-shaped external plate 54 is slidably installed in the groove, and a cross groove 55 provided on the external box 52 is symmetrically provided above the external plate 54, and a cross plate 56 fixed to the external plate 54 is slidably installed in the cross groove 55, and a movable plug 541 for blocking the center tube 53 is fixedly installed in the middle of the upper end face of the external plate 54.

[0045] When grinding the circular ring in the middle of the electric drive bridge housing, the electric slider opens and drives the sliding frame 4 to slide in the rectangular slide groove until the outer plate 54 fits with the outer edge of the circular ring in the middle of the bridge housing. At this time, the outer plate 54 moves up in contact with the bridge housing, and then the outer plate 54 is opened to grind the burrs on the outside of the bridge housing. When the outer plate 54 moves up, it simultaneously drives the moving plug 541 to move up. When the moving plug 541 moves up, the blockage of the central tube 53 is cancelled. At this time, the coolant in the cooling box 5 flows through the central tube 53 to the outer plate 54, and finally the coolant flows to the contact surface between the outer plate 54 and the bridge housing. Through the setting of the coolant, not only can the outer plate 54 be cooled when grinding the outside of the bridge housing, but also the dust generated during grinding can be washed away.

[0046] As attached Figure 8 As shown, the aperture grinding unit includes a fixed frame 6, and dovetail grooves 61 are provided on both sides of the inner wall of the fixed frame 6. A dovetail block is slidably installed in the dovetail groove 61 through an electric slider, and a cylinder 62 is fixedly installed on the side of the dovetail block away from the dovetail groove 61. The telescopic ends of multiple cylinders 62 are jointly installed with a support frame 63 located below the fixed frame 6, and a cross bar 64 is fixedly installed in the middle of the support frame 63. A mounting plate 65 is installed in the middle of the cross bar 64 through motor rotation, and a support box 68 is fixedly installed on the lower end surface of the mounting plate 65. Side grooves 650 are provided on both sides of the mounting plate 65, and a regulating block 651 is slidably installed in the side groove 650. Adjustment plates 652 are installed on both sides of the inner wall of the fixed frame 6 through motor rotation, and the adjustment plate 652 is hinged to the regulating block 651 at one end away from the fixed frame 6.

[0047] When grinding the circular hole in the middle of the bridge housing, the motor is turned on to drive the adjustment plate 652 to rotate. When the adjustment plate 652 rotates, it drives the control block 651 to slide in the side groove 650. At this time, the mounting plate 65 is flipped on the cross bar 64 until the support box 68 is on the same axis as the middle of the bridge housing. Then, the slider is driven to open and drive the support box 68 to move into the center hole of the bridge housing. Then, the electric push rod 69 is controlled to push forward. When the electric push rod 69 pushes forward, it simultaneously drives multiple pushing plates 691 to expand outward. At this time, multiple grinding plates 692 are expanded at the circular hole in the center of the bridge housing until they conflict with the center of the bridge housing. Then, the motor is turned on to drive the storage box 66 to rotate. While the storage box 66 rotates, it drives multiple grinding plates 692 to perform rotational grinding in the circular ring in the center of the bridge housing, thereby realizing the grinding operation of the circular hole in the middle of the bridge housing.

[0048] An electric push rod 69 is fixedly installed in the inner cavity of the support box 68, and a circumferentially arranged rotating plate 681 is hinged on the support box 68. A grinding plate 692 is hinged between multiple rotating plates 681. A circumferentially arranged through groove is opened on the outer wall of the support box 68, and a pushing plate 691 is hinged to the end of the electric push rod 69 in the through groove. The end of the pushing plate 691 away from the electric push rod 69 is hinged to the grinding plate 692.

[0049] A conduction tube 67 is installed at one end of the storage box 66. The end of the conduction tube 67 away from the storage box 66 is connected to the side wall of the center tube 53. A liquid outlet is provided on the outer wall of the grinding plate 692. A branch pipe is installed between the top of the grinding plate 692 and the storage box 66. The coolant in the storage box 66 can be supplied to the liquid outlet through the branch pipe.

[0050] As attached Figure 9 As shown, the paint spraying unit includes a paint spraying box 7 for storing paint materials. External sleeves 71 are fixedly installed on both sides of the outside of the paint spraying box 7. A plurality of equally spaced arc frames 72 are fixedly installed on the lower end surface of the paint spraying box 7. A driving rod 73 is installed between the two external sleeves 71 through the rotation of a motor. A plurality of equally spaced driving wheels 74 are installed on the driving rod 73. An arc groove is provided on the inner wall of the arc frame 72.

[0051] The motor is turned on to drive the transposition shaft 41 to rotate. When the transposition shaft 41 rotates, the transposition plate 42 is synchronously driven to rotate. When the transposition plate 42 rotates, the painting unit and the outer ring grinding unit are transposed, thereby facilitating the subsequent painting operation of the bridge housing.

[0052] When the polished bridge housing is to be painted, the motor is turned on to drive the driving rod 73 to rotate. When the driving rod 73 rotates, the driving wheel 74 drives the surrounding ring 75 to rotate. When the surrounding ring 75 rotates, the nozzle 77 is turned on to simultaneously spray paint the inner and outer walls of the circular hole in the middle of the bridge housing. In addition, the setting of the transmission pipe 78 can also continuously transmit and supply the paint in the paint box 7 to the nozzle 77.

[0053] A surrounding ring 75 is slidably installed in the arc groove, a through groove is opened in the middle of the arc frame 72, and a plurality of teeth 76 arranged at equal intervals are fixedly installed on the outside of the surrounding ring 75. The driving wheel 74 is placed in the through groove and engages with the teeth 76. A nozzle 77 is fixedly installed in the middle of the side of the surrounding ring 75 away from the arc frame 72, and a transmission pipe 78 connected to the paint spray box 7 is provided on one side of the nozzle 77.

[0054] The arc-shaped frame 72 is arranged in an arc shape, which can block the spray head 77 from spraying the paint and prevent the paint from splashing when spraying.

[0055] A magnetic frame 82 is rotatably installed in the middle of the recovery box 8, and one end of the magnetic frame 82 passes through the recovery box 8. Pulleys are fixedly installed on one side of the magnetic frame 82 and the rotating frame 31 on one side, and a belt is installed between the pulleys. A recovery pipe 81 is installed between the recovery box 8 and the paint spray box 7.

[0056] The setting of the recycling box 8 can recycle the paint that falls when the bridge shell is painted, so that it can be recycled and reused. When the motor is turned on to drive the rotating frame 31 to rotate, the rotation of the rotating frame 31 can replace multiple bridge shells so as to carry out continuous processing operations of batch bridge shells, and when the rotating frame 31 rotates, the setting of the pulley and the belt can also drive the rotation of the magnetic suction frame 82. The setting of the magnetic suction frame 82 can also continuously filter and adsorb the paint in the recycling box 8, and then filter out the iron powder that falls during grinding.

[0057] When the steering plate 652 rotates downward, it drives the regulating block 651 to slide in the side groove 650. At this time, the mounting plate 65 rotates on the cross bar 64 so that the support box 68 and the bridge housing are coaxial.

[0058] When in use, the placement unit is set to place and fix multiple bridge shells, and the bridge shells of the electric drive bridge can be rotated and transposed in turn through the rotation of the placement unit, so that it can perform continuous operation. The outer ring grinding unit is set to perform targeted grinding operations on the outer edge of the center of the bridge shell, and the aperture grinding unit provided on one side of the outer ring grinding unit can grind the outer edge of the center of the bridge shell while the outer ring grinding unit is grinding the outer edge of the center of the bridge shell. The aperture grinding unit can also cooperate with it to grind the inside of the circular ring in the middle of the bridge shell, which effectively solves the problem of difficulty in grinding the outer edge and inner wall of the center of the bridge shell. The motor is turned on to drive the transposition shaft 41 to rotate, and the transposition shaft 41 rotates When the shift plate 42 is rotated, the shift plate 42 can quickly switch the positions of the outer ring grinding unit and the painting unit, and then quickly perform the painting operation on the inside and outside after the grinding operation on the center of the bridge housing, thereby realizing the continuous grinding and painting of the bridge housing. Compared with the existing external processing device for the electric drive bridge housing, the present invention can synchronously grind the outer edge and inner wall of the middle ring of the bridge housing, effectively overcoming the problem of difficult grinding in the middle of the electric drive bridge. At the same time, the outer ring grinding unit and the painting unit can be quickly and conveniently switched, so that after the grinding of the middle ring of the bridge housing is completed, the painting operation on the outside of the bridge housing can be carried out immediately.

[0059] Open the two telescopic plates 3 and bring them close to each other, so that the side plates 30 can contact the two side walls of the electric drive bridge when they are close to each other, and the rubber blocks on the two side plates 30 are placed inside the bridge housing to prevent the electric drive bridge housing from sliding during grinding. When grinding the circular ring in the middle of the electric drive bridge housing, the electric slider is opened to drive the sliding frame 4 to slide in the rectangular slide groove until the outer plate 54 is fitted with the outer edge of the circular ring in the middle of the bridge housing. At this time, the outer plate 54 moves up in contact with the bridge housing, and then the outer plate 54 is opened to The burrs on the outside of the axle housing can be polished, and when the outer plate 54 moves upward, the movable plug 541 is simultaneously driven to move upward. When the movable plug 541 moves upward, the blockage of the central tube 53 is cancelled. At this time, the coolant in the cooling box 5 flows through the central tube 53 to the outer plate 54, and finally flows to the contact surface between the outer plate 54 and the axle housing. The provision of the coolant can not only cool the outer plate 54 when polishing the outside of the axle housing, but also wash away the dust generated during the polishing.

[0060] When grinding the circular hole in the middle of the bridge housing, the motor is turned on to drive the adjustment plate 652 to rotate. When the adjustment plate 652 rotates, it drives the regulating block 651 to slide in the side groove 650. At this time, the mounting plate 65 is flipped on the cross bar 64 until the support box 68 and the middle of the bridge housing are on the same axis. Then, the slider is driven to open and drive the support box 68 to move into the center hole of the bridge housing. Then, the electric push rod 69 is controlled to push forward. When the electric push rod 69 pushes forward, it simultaneously drives multiple pushing plates 691 to expand outward. At this time, multiple grinding plates 692 are expanded at the circular hole in the center of the bridge housing until they conflict with the center of the bridge housing. Then, the motor is turned on to drive the storage box 66 to rotate. While the storage box 66 rotates, it drives multiple grinding plates 692 to perform rotational grinding in the circular ring in the center of the bridge housing, thereby realizing the grinding operation of the circular hole in the middle of the bridge housing.

[0061] The motor is turned on to drive the transposition shaft 41 to rotate. When the transposition shaft 41 rotates, the transposition plate 42 is driven to rotate synchronously. When the transposition plate 42 rotates, the paint spraying unit and the outer ring grinding unit are transposed, so as to facilitate the subsequent painting operation of the bridge housing. When the bridge housing after grinding is painted, the motor is turned on to drive the driving rod 73 to rotate. When the driving rod 73 rotates, the surrounding ring 75 is driven to rotate through the driving wheel 74. When the surrounding ring 75 rotates, the nozzle 77 is turned on to spray paint the inner and outer walls of the circular hole in the middle of the bridge housing at the same time. In addition, the setting of the transmission pipe 78 can also continuously transmit and supply the paint in the paint spraying box 7 to the nozzle 77. The arc frame 72 is set in an arc shape, which can resist the spraying of paint by the nozzle 77 to prevent the paint from splashing when it is sprayed. The setting of the recovery box 8 can recover the paint that falls when the bridge shell is painted, so that it can be recycled and reused. When the motor is turned on to drive the rotating frame 31 to rotate, the rotation of the rotating frame 31 can replace multiple bridge shells so as to carry out continuous processing operations of batch bridge shells, and when the rotating frame 31 rotates, the setting of the pulley and belt can also drive the rotation of the magnetic suction frame 82. The setting of the magnetic suction frame 82 can also continuously filter and adsorb the paint in the recovery box 8, and then filter out the iron powder that is polished and dropped.
