Description

Technical Field

[0001] The present invention relates to the field of motor assembly technology, in particular to a gasket bearing assembly screw locking current adjustment device and an operating method thereof. Background Art

During the assembly process of the motor, the motor and the gear box need to be press-fitted, and the pressed motor and gear box assembly parts need to be screwed to tightly assemble the motor and gear box together; and before assembling the motor gear box, gaskets and bearings need to be installed.

[0003] In the prior art, the assembly of motor gear boxes is usually completed in steps using multiple mechanisms, and it is not possible to automatically complete the continuous operations from feeding to assembly to discharging at one time, resulting in low assembly efficiency. At the same time, the gear box lacks isolation and correction mechanisms during transportation, which makes it easy for the gear box to be crowded during transportation and difficult to position correctly. Moreover, the positioning mechanism during the gasket loading process has a single function, low positioning accuracy, and is not convenient for gasket transfer. In addition, this type of assembly equipment does not power on the motor during the screw locking process, and cannot ensure the smooth operation of the assembled motor gear box. It also does not have a centering correction mechanism, and cannot evenly adjust the operating friction of the motor shaft, which is defective in improving product performance.

[0024] An operating method for the gasket bearing assembly screw locking current adjustment device includes the following steps:

The synchronous material transfer mechanism moves the gear box with the gasket and bearing installed forward to wait for the motor to be installed; the motor loading mechanism starts loading the motor, and the motor transfer mechanism transfers the motor to the motor shaft oiling mechanism for oiling;

[0030] S6. The oiled motor is transferred by the motor transfer mechanism to the assembly mechanism for assembly of the motor and the gear box;

[0031] S7, the synchronous material moving mechanism moves the assembled motor gear box forward, and the screw locking mechanism installs the screws at the joint of the motor gear box to firmly connect the motor and the gear box. During the process of tightening the screws, the motor is powered on and operates.

[0032] S8. After the screws are tightened, the motor gear box is transferred to the centering correction mechanism for hammering and centering operation;

[0033] S9. Qualified products are transferred to the unloading mechanism for unloading, and unqualified products are transferred to the defective product collection mechanism.

[0034] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical scheme that by integrating the gear box conveying and positioning mechanism, the synchronous material moving mechanism, the gasket loading and installation mechanism, the bearing loading and installation mechanism, the motor loading mechanism, the motor shaft oiling mechanism, the assembly mechanism, the screw locking mechanism, the centering correction mechanism, the defective product collection mechanism and the unloading mechanism on the frame to form a device for assembling gaskets and bearings for motor gear boxes, locking screws and adjusting current. The device realizes automatic loading, transfer, conveying and installation of gear boxes, gaskets, bearings, motors and combinations, which makes the assembly efficiency of motor gear boxes higher, saves a lot of manual labor, improves product quality and reduces production costs.

[0035] At the same time, the device also has the following advantages:

[0036] First, by using a positioning device and isolation assembly in conjunction, the positioning device can correct tooth box deviations caused by vibration during conveyance, and the vertical positioning assembly is used to fix the tooth box vertically, correcting its placement and assisting with subsequent assembly alignment. Furthermore, the isolation assembly automatically isolates subsequent tooth boxes during the positioning of the previous one, preventing congestion and making tooth box conveyance more orderly and improving loading efficiency.

[0037] Second, by coordinating the vibration basin, straight vibration feeder, gasket transfer assembly and gasket positioning assembly, the gasket can be accurately positioned after loading with the cooperation of the rotation positioning unit, fixing unit, lifting unit and laser sensor, thereby improving the gasket installation accuracy; the overall structure of the rotation positioning unit, fixing unit, lifting unit and laser sensor is cleverly and compactly coordinated, realizing the automatic positioning, fixing and lifting actions of the gasket, which promotes the subsequent precise assembly of the gasket, while saving manual labor and improving production efficiency.

[0038] Third, by setting up a power-on component in the screw locking mechanism, the motor can be powered on while the motor gear box is being screwed, avoiding the motor from being stuck due to excessive screw tightening and the occurrence of unstable current; the current test can be performed simultaneously during the screw locking operation of the motor gear box, thereby improving product quality, reducing the subsequent inspection process of the motor, and reducing production costs.

[0039] Fourth, by integrating the corrective sliding assembly, fixed assembly, rotating assembly, tapping assembly, and electrical connection assembly into a centering correction mechanism, this mechanism evenly taps the motor's snout, ensuring more uniform contact between the motor shaft and the snout, reducing localized excessive friction and improving motor operation smoothness. This improves motor operating stability and product quality, extending the motor's service life.

[0108] S4. The tooth box with the gasket installed is transferred to the next intermediate transfer seat by the synchronous material transfer mechanism; the bearing loading assembly loads the bearing; the bearing installation assembly installs the bearing into the tooth box;

[0109] S5. The synchronous material transfer mechanism transfers the gear box with the gasket and bearing installed to the next intermediate transfer seat, waiting for the motor to be installed; the motor loading mechanism starts loading the motor, and the motor transfer mechanism transfers the motor to the motor shaft oiling mechanism for oiling;

[0110] S6. The oiled motor is transferred by the motor transfer mechanism to the assembly mechanism for assembly of the motor and the gear box;

[0111] S7. The synchronous material transfer mechanism transfers the assembled motor gear box to the next intermediate transfer seat, and the screw locking mechanism installs screws at the joint of the motor gear box to securely connect the motor and gear box to each other. During the process of tightening the screws, the motor is powered on and operates.

[0112] S8. After the screws are tightened, the motor gear box is transferred to the centering correction mechanism for hammering and centering operation;

[0113] S9. Qualified products are unloaded by the unloading mechanism, and unqualified products are transferred to the defective product collection mechanism. The motor 111 drives the conveyor belt 112 to transfer the defective products to the defective product collection area.

[0114] The specific working principle of the device is as follows:

[0115] The tooth box transport and positioning mechanism 20 transports the tooth box via the first linear vibrating feeder 22 to the accommodating space 2311 of the positioning device 23. Due to its own weight distribution, the tooth box may tilt under the vibration of the first linear vibrating feeder 22, causing the front end of the tooth box to diagonally insert into the clearance slot 2314, requiring correction. After the laser sensor 2333 of the lateral correction assembly 233 detects the front end of the tooth box entering the clearance slot 2314, the correction drive cylinder 2332 drives the correction block 2331 forward, pushing the front end of the tooth box out of the clearance slot 2314 and aligning the tooth box. The displacement sensor 2334 monitors the movement of the correction block 2331 in real time to prevent excessive movement and overcorrection of the front end of the tooth box. After the tooth box is aligned, the first lateral drive cylinder 2322 drives the slide 2321 forward to slide below the vertical positioning assembly. The vertical positioning cylinder 2341 drives the positioning column 2342 downward to press the tooth box firmly, awaiting transfer. Before the tooth box is positioned and tightened, the isolation assembly 24 will isolate the tooth box behind from the tooth box to prevent the tooth box from being crowded and unable to be positioned; specifically, the laser sensor 2333 detects that the front end of the tooth box enters the make way groove 2314, indicating that the tooth box has been delivered to its position; at this time, the isolation drive cylinder 243 will drive the step block 242 to move forward, so that the upper step portion of the step block 242 slides to contact the lower end of the isolation column 241 (the isolation column 241 is normally in a downward state under the action of the spring, that is, the upper end of the isolation column 241 is in a downward state under the action of the spring, that is, the upper end of the isolation column 241 is in a downward state under the action of the spring, that is, the upper end of the isolation column 241 is in a downward state under the action of the spring, that is, the upper end of the isolation column 241 is in a downward state The end does not exceed the upper surface of the first linear vibrating feeder 22 to avoid blocking the movement of the tooth box), so that the isolation column 241 is pushed upward and exceeds the upper surface of the first linear vibrating feeder 22 to block the tooth box behind; after the front tooth box is positioned, tightened and transferred away, the isolation drive cylinder 243 drives the step block 242 to move backward, so that the lower step part slides to contact the isolation column 241, and the isolation column 241 is reset under the action of the spring 245. The next tooth box is driven by the first linear vibrating feeder 22 to move forward to the accommodating space 2311, and the cycle is repeated.

[0116] After the tooth box arrives at the vertical positioning component 234, the clamping cylinder of the tooth box transfer mechanism 130 moves to the vertical positioning component 234 under the drive of the horizontal drive cylinder and the vertical lifting drive cylinder to clamp the tooth box and the rotating cylinder rotates the tooth box from a lying state to a vertical state; then it is transferred to the middle transfer seat 31 of the synchronous material moving mechanism 30, and the second horizontal movement drive cylinder 37 of the synchronous material moving mechanism 30 will drive the horizontal movement slide 34 to drive the clamping cylinder 36 to move to correspond to the middle transfer seat 31, and then the first vertical movement drive cylinder 38 drives the vertical movement slide 35 to move downward, so that the clamping cylinder 36 clamps the tooth box on the middle transfer seat 31, and the first vertical movement drive cylinder 38 moves the clamping cylinder 36 downward again, so that the clamping cylinder 36 places the clamped tooth box in the middle transfer seat 31 at the corresponding gasket loading and installation mechanism 40, waiting for the gasket to be installed.

[0117] The gasket in the first vibrating basin 411 of the gasket feeding device 41 is transported to the gasket transfer assembly 413 through the second straight vibration feeder 412, the material sensor 416 detects the incoming material, and the transfer clamp 4131, driven by the transfer drive cylinder 4132, clamps the gasket arriving at the discharge end of the second straight vibration feeder 412 and places it on the rotating seat 41411 of the gasket positioning assembly 414; the rotating seat 41411 has an air hole, and the vacuum sounder is connected to the air hole of the rotating seat 41411 through the shaft of the driven pulley 41415, thereby adsorbing the gasket on the rotating seat 41411; the motor 41412 drives the pulley group 41413 to operate, and the driven pulley 41415 drives the rotating seat 41411 to rotate for positioning. At this time, the laser sensor unit 4144 emits light onto the gasket. The signal and the reflected signal determine the gasket (there is a notch on the gasket, and the laser sensor unit 4144 determines the distance through the transmitted signal and the reflected signal. The distance between the notch position and the non-notch position is different, so it is used to determine whether it has been rotated into place); if it has been rotated into place, the motor 41412 stops driving, and the positioning drive cylinder 41422 of the fixing unit 4142 drives the positioning fork 41421 to move forward to fix the gasket (after the motor 41412 stops driving, the gasket will still inertially rotate to a certain angle, and the positioning fork 41421 will fork the gasket forward and apply a small rotational force to the gasket to achieve the optimal position of the gasket); the slot switch 41423 will generate an induction signal to the sensor sheet 41424 installed on the positioning fork 41421 to determine the moving position of the positioning fork 41421 and prevent excessive movement. After the gasket is fixed, the positioning fork 41421 will retract, the vacuum sounder will stop working, and the lifting plate 41431 of the lifting unit 4143 will lift the gasket upward and away from the rotating seat 41411 under the drive of the lifting drive cylinder 41432.

[0118] The gasket suction rod 4221 (hollow inside, using vacuum adsorption) of the gasket installation device 42 clamps the gasket on the lifting plate 41431 and installs it in the hole of the gear box under the drive of the third transverse drive cylinder 4223 and the lifting drive cylinder 4222 (the gear box has a worm accommodating hole, the worm is connected to the motor shaft end, and the worm is installed in the worm accommodating hole; specifically, before installing the worm, it is necessary to first install the gasket at the bottom of the worm accommodating hole, and then install the bearing above the gasket. When the worm is installed, it will pass through the bearing, and the front end of the worm will contact the gasket).

[0119] The tooth box with the gasket installed is transferred by the clamping cylinder 36 of the synchronous material transfer mechanism 30 to the next transfer seat 31, and the transfer seat 31 corresponds to the bearing loading and installation mechanism 50; the second vibration basin 511 and the third straight vibration feeder 512 of the bearing loading assembly 51 transport the bearings to the bearing transverse movement device 513; the bearing suction rod 522 (vacuum suction) of the bearing installation assembly 52, driven by the fifth transverse movement drive cylinder 523 and the second vertical movement drive cylinder 524, sucks the bearings displaced by the bearing transverse movement device 513 and installs them in the tooth box.

[0120] The synchronous material transfer mechanism 30 transfers the gear box with gaskets and bearings installed to the next transfer seat 31, which corresponds to the assembly mechanism 80 workstation; the motor loading mechanism 60 starts to load the motor, and the motor loading mechanism 60 adopts the traditional motor combined with the conveyor belt operation mode for loading; when the motor reaches the motor transfer mechanism 140, the motor transfer mechanism 140 adopts horizontal and vertical drive to cooperate with the clamping cylinder to clamp the motor and transfer it to the motor shaft oiling mechanism 70; the motor transfer mechanism 140 adopts a rotary drive motor to drive the clamping cylinder to rotate, so that the motor shaft penetrates into the oiling pan 72 for circumferential oiling operation, and the oiled motor is transferred by the motor transfer mechanism 140 to the motor receiving cylinder 82 of the assembly mechanism 80, and the motor receiving cylinder 82 receives the motor from the clamping cylinder of the motor transfer mechanism 140 to complete the handover of the motor. Then, the motor receiving cylinder 82 is driven by the horizontal driving cylinder and the press-fitting driving device 85 to vertically insert the motor into the gear box on the intermediate transfer seat 31; the press-fitting cylinder 84 drives the lower pressing block 86 to press the motor further into the gear box, so that the worm at the end of the motor shaft is inserted into the hole of the gear box where the gasket and bearing have been installed; at this point, the motor and the gear box are assembled.

[0121] The synchronous material transfer mechanism 30 transfers the assembled motor gear box to the next transfer seat 31, which corresponds to the workstation of the screw locking mechanism 90; the three screwdrivers 92 of the screw locking mechanism 90 are connected to the screw feed box, and the screws are installed at the joint of the motor gear box under the drive of the lifting drive device 93, so that the motor and the gear box are fixed to each other; in the process of tightening the screws, the electrode of the power component 94 is connected to the power socket of the motor under the drive of the power drive cylinder, and the motor is powered on to prevent the motor from being blocked after the screws are tightened; tightening the screws while the motor is powered on can make the tightening force of the three screws more uniform, and avoid the phenomenon of the motor being stuck due to over-tightening of a part. After the screws are locked, the motor gear box is transferred to the centering correction mechanism 100 by the manipulator. The manipulator is a conventional handling manipulator, which is not shown in the drawings and will not be described here.

[0122] The motor gear box is transferred to the correction slide 1022 of the centering correction mechanism 100, and the pressure seat 1032 under the fixing component 103 is driven by the pressing drive cylinder 1033 to press the motor gear box downward and fix it on the bottom support 1031; the correction sliding drive device 1021 drives the correction slide 1022 to move forward to the knocking component 106; the motor 10632 of the swing unit 1063 drives the pulley group 10633 to operate, so that the output shaft 10634 rotates, and the turntable 10631 rotates accordingly; the collision unit 1062 installed on the turntable 10631 swings 90 degrees with the turntable 10631; the collision drive cylinder 10622 drives the collision block 10623 to slide back and forth along the slide rail 10624, simulating the action of punching and retracting the fist toward the pig mouth position of the motor (the motor pig mouth refers to a part of the rear end of the motor shaft extending out of the outside of the motor housing, and a portion extending from the rear end of the motor shaft is set on the motor housing There is a covering component, which completely covers the protruding part of the rear end of the motor shaft, and the inner wall of the covering is in sliding contact with the rear end of the motor shaft, and knocking the pig's mouth is knocking the covering, so that the edge of the covering is in uniform contact with the rear end of the motor shaft, thereby making the operation more stable); during the knocking process, the motor 1041 of the rotating component 104 drives the rotating disk 1042 to rotate, and the motor gear box rotates accordingly, so that the knocking can be evenly performed around the circumference of the pig's mouth, avoiding the situation of excessive local knocking; at the same time, the power plug of the power connection component 107 is connected to the power connection socket of the motor under the drive of the power drive cylinder to energize the motor, that is, during the process of knocking the motor pig's mouth position, the motor is in a energized state; this can improve the uniformity of the contact between the motor shaft and the pig's mouth, and at the same time, it can detect in real time whether the motor current is stable. When the motor current is within a stable range, the product is qualified. If the current is still unstable after multiple knocks, the product is defective. In addition, during the hammering process, the two sets of hammering components use an alternating hammering method, so that the contact force between the motor shaft and the pig's mouth is uniform and symmetrical during the hammering process, further improving product quality.

[0123] Qualified products are transferred and unloaded by the robot (unloading mechanism 120 ), and unqualified products are transferred by the robot to the defective product collection mechanism 110 . The motor 111 drives the conveyor belt 112 to transfer the defective products to the defective product collection area.

[0124] The design focus of the present invention is to form a device for assembling gaskets, bearings, motors and combinations thereof by integrating the gear box conveying and positioning mechanism, synchronous material moving mechanism, gasket loading and installation mechanism, bearing loading and installation mechanism, motor loading mechanism, motor shaft oiling mechanism, assembly mechanism, screw locking mechanism, centering correction mechanism, defective product collection mechanism and unloading mechanism on the frame. The device realizes automatic loading, transfer, conveying and installation of gear boxes, gaskets, bearings, motors and combinations, which makes the assembly efficiency of motor gear boxes higher, saves a lot of manual labor, improves product quality and reduces production costs.

[0125] At the same time, the device also has the following advantages:

[0126] First, by using a positioning device and isolation assembly in conjunction, the positioning device can correct tooth box deviations caused by vibration during conveyance, and the vertical positioning assembly is used to fix the tooth box vertically, correcting its placement and assisting with subsequent assembly alignment. Furthermore, the isolation assembly automatically isolates subsequent tooth boxes during the positioning of the previous one, preventing congestion and making tooth box conveyance more orderly and improving loading efficiency.

[0127] Second, by coordinating the vibration basin, straight vibration feeder, gasket transfer assembly and gasket positioning assembly, the gasket can be accurately positioned after loading with the cooperation of the rotation positioning unit, fixing unit, lifting unit and laser sensor, thereby improving the gasket installation accuracy; the overall structure of the rotation positioning unit, fixing unit, lifting unit and laser sensor is cleverly and compactly coordinated, realizing the automatic positioning, fixing and lifting actions of the gasket, which promotes the subsequent precise assembly of the gasket, while saving manual labor and improving production efficiency.

[0128] Third, by setting up a power-on component in the screw locking mechanism, the motor can be powered on while the motor gear box is being screwed, avoiding the motor from being stuck due to excessive screw tightening and the occurrence of unstable current; the current test can be performed simultaneously during the screw locking operation of the motor gear box, thereby improving product quality, reducing the subsequent inspection process of the motor, and reducing production costs.

[0129] Fourth, by integrating the corrective sliding assembly, fixed assembly, rotating assembly, tapping assembly, and electrical connection assembly into a centering correction mechanism, this mechanism evenly taps the position of the motor's pigtail, ensuring more uniform contact between the motor shaft and the pigtail, reducing localized excessive friction and improving motor operation smoothness. This improves motor operating stability and product quality, extending the motor's service life.

[0130] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
