Description

Technical Field

[0001] This utility model relates to the field of motor gear testing technology, and in particular to a motor gear testing feeding mechanism. Background Technology

[0002] In the production and testing process of motor gears, the loading process before torque testing is a fundamental step to ensure the smooth progress of the test. At present, the loading operation for motor gear testing in the industry still generally relies on manual labor, that is, the operator manually places the motor gears to be tested one by one onto the test fixture station.

[0003] Manual material loading is extremely labor-intensive, easily causing fatigue and affecting operational efficiency. Manual material loading requires dedicated personnel, and with rising labor costs, long-term operation will significantly increase the company's production costs. More importantly, manual operation has limited speed, making it difficult to match the needs of high-speed testing equipment in mass production scenarios of motor gears. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a motor gear testing and feeding mechanism.

[0005] This utility model proposes a motor gear testing and feeding mechanism, including an equipment cabinet. A vertical vibrator, a gear feeding fixture, and a first-stage horizontal drive module are respectively installed on the top of the equipment cabinet. The vertical vibrator internally conveys several motor gears. A lifting drive module is installed at the drive end of the first-stage horizontal drive module, and a second-stage material-retrieving drive module is installed at the drive end of the lifting drive module. The first-stage horizontal drive module and the lifting drive module respectively adjust the horizontal and vertical positions of the second-stage material-retrieving drive module. The second-stage material-retrieving drive module places the motor gears conveyed by the vertical vibrator onto several workstations of the gear feeding fixture.

[0006] Furthermore, the inlet of the linear vibrator is connected to the outlet of the vibrating disc, and a stop block is installed on the top of the equipment cabinet to block the outlet of the linear vibrator and prevent the motor gears from feeding material.

[0007] Furthermore, the gear feeding fixture includes a first guide rail and a feeding drive cylinder mounted on the top of the equipment cabinet. The upper part of the first guide rail is slidably connected to the fixture base plate, and the telescopic end of the feeding drive cylinder is connected to the fixture base plate.

[0008] Furthermore, a number of equidistant positioning posts are installed at the top of the fixture base plate. A sleeve is installed on the outside of the positioning post, and an insertion hole is opened inside the sleeve. The positioning post is inserted into the insertion hole.

[0009] Furthermore, a slot is formed at the top of the positioning post, and keyways are symmetrically formed on the surface of the motor gear shaft. The motor gear shaft is located in the insertion hole, and the keyways engage with the slot.

[0010] Furthermore, the transverse drive module includes a bracket mounted on the top of the equipment cabinet. A lead screw is rotatably connected to the front of the bracket, and a motor is mounted at the end of the bracket. The drive end of the motor is connected to the lead screw, and the external thread of the lead screw is connected to a drive seat. A second guide rail is also symmetrically mounted on the front of the bracket, and the drive seat slides outside the second guide rail.

[0011] Furthermore, the lifting drive module includes a lifting drive cylinder and a third guide rail mounted on the front of the drive seat. The lifting seat is slidably connected to the outside of the third guide rail, and the telescopic end of the lifting seat is connected to the lifting seat.

[0012] Furthermore, the two-stage material handling drive module includes a material transfer drive cylinder and a fourth guide rail installed on the front of the lifting seat. The fourth guide rail is slidably connected to a movable seat. The telescopic end of the material transfer drive cylinder is connected to the movable seat. A suction nozzle is installed inside the movable seat.

[0013] The beneficial effects of this utility model are as follows: the orderly conveying of motor gears is achieved through a linear vibrator, and the coordinated action of a first-stage transverse drive module, a lifting drive module, and a second-stage material picking drive module completes automated material picking and placing. With the precise positioning structure of the gear loading fixture, it replaces the traditional manual loading method, effectively reducing the intensity of manual labor and production costs.

[0023] Reference Figure 1-8 This utility model proposes a motor gear testing and feeding mechanism, including an equipment cabinet 1, on the top of which are fixedly installed a vertical vibrator 2 (the specific structure and principle of the vertical vibrator 2 are known technologies and will not be detailed here), a gear feeding fixture 3, and a horizontal drive module 4. The inlet of the vertical vibrator 2 is connected to the outlet of an external vibrating plate. The vibrating plate sorts and arranges the disordered motor gears 8 and continuously feeds them into the vertical vibrator 2. The vertical vibrator 2, through its own vibration, smoothly feeds several motor gears 8 along the conveying track towards the outlet. At the same time, a stop block 7 is fixedly installed at the top of the equipment cabinet 1 corresponding to the outlet of the vertical vibrator 2. The stop block 7 blocks the outlet of the vertical vibrator 2, so that the motor gears 8 to be fed to the outlet are blocked, preventing them from falling directly and ensuring that the motor gears 8 are waiting for the feeding operation in an orderly manner at the outlet.

[0024] The gear feeding fixture 3 includes a first guide rail 31 and a feeding drive cylinder 32 installed at the top of the equipment cabinet 1. The first guide rail 31 is set in a horizontal direction, and a fixture base plate 33 is slidably connected to its upper part. The bottom of the fixture base plate 33 is provided with a slider that matches the first guide rail 31 to ensure smooth sliding. The telescopic end of the feeding drive cylinder 32 is fixedly connected to the fixture base plate 33 through a floating joint. When the feeding drive cylinder 32 telescopically extends or retracts, it can drive the fixture base plate 33 to slide horizontally back and forth along the first guide rail 31, thereby conveying several neatly arranged motor gears 8 to the next testing process.

[0025] In addition, a number of equidistant positioning posts 34 are evenly installed on the top of the fixture base plate 33. A sleeve 35 is installed on the outside of the positioning post 34. The sleeve 35 has a matching insertion hole 36 inside. The positioning post 34 is inserted into the insertion hole 36. In order to further constrain the motor gear 8, a slot 37 is provided on the top of the positioning post 34. A keyway 81 is symmetrically provided on the surface of the motor gear 8 shaft. When the motor gear 8 is placed in the gear loading fixture 3, its shaft is exactly located in the insertion hole 36, and the keyway 81 and the slot 37 are precisely engaged. The circumferential rotation of the motor gear 8 is restricted by the cooperation of the mechanical structure.

[0026] A horizontal drive module 4 is used to achieve horizontal position adjustment. It includes a bracket 41 installed at the top of the equipment cabinet 1. A lead screw 42 is rotatably connected to the front of the bracket 41 through a bearing seat. The lead screw 42 is set in the horizontal direction. A motor 43 is fixedly installed at the end of the bracket 41 through a motor seat. The drive end of the motor 43 is fixedly connected to one end of the lead screw 42 through a coupling. The motor 43 is a servo motor, which can achieve precise speed control. A drive seat 44 is threadedly connected to the external of the lead screw 42. A second guide rail 45 is also symmetrically installed on the front of the bracket 41. The second guide rail 45 is set parallel to the lead screw 42. The bottom of the drive seat 44 is provided with a slider that matches the second guide rail 45, so that the drive seat 44 can slide smoothly outside the second guide rail 45. When the motor 43 drives the lead screw 42 to rotate, the drive seat 44 moves horizontally along the lead screw 42 and the second guide rail 45 under the action of the thread, so as to achieve precise adjustment of the horizontal position.

[0027] A lifting drive module 5 is installed on the drive seat 44 of a horizontal drive module 4. The lifting drive module 5 includes a lifting drive cylinder 51 and a third guide rail 52 installed on the front of the drive seat 44. The third guide rail 52 is arranged in the vertical direction and a lifting seat 53 is slidably connected to its outside. The side of the lifting seat 53 is provided with a slider that matches the third guide rail 52. The extension and retraction end of the lifting drive cylinder 51 is fixedly connected to the lifting seat 53 through a connector. When the lifting drive cylinder 51 extends and retracts, it drives the lifting seat 53 to reciprocate in the vertical direction along the third guide rail 52 to achieve position adjustment in the height direction.

[0028] The lifting drive module 5 has a lifting base 53 equipped with a two-stage material handling drive module 6. The two-stage material handling drive module 6 includes a material transfer drive cylinder 61 and a fourth guide rail 62 installed on the front of the lifting base 53. The fourth guide rail 62 is set in a horizontal direction and is slidably connected to a movable seat 63. The side of the movable seat 63 is provided with a slider that matches the fourth guide rail 62. The telescopic end of the material transfer drive cylinder 61 is fixedly connected to the movable seat 63. A suction nozzle 64 is installed inside the movable seat 63. The suction nozzle 64 is connected to the air port of an external vacuum generator through an air pipe, which can generate suction force. When the material transfer drive cylinder 61 extends or retracts, it drives the movable seat 63 to slide horizontally along the fourth guide rail 62, thereby realizing the switching of the position of the suction nozzle 64 between the material handling point and the material dispensing point.

[0029] Work process:

[0030] The vibrating disc continuously conveys the sorted motor gears 8 to the straight vibrator 2. The straight vibrator 2 conveys the motor gears 8 along the track to the outlet through vibration, where they are blocked by the stop block 7, forming a state where they are ready to be picked up.

[0031] The motor 43 of the horizontal drive module 4 drives the lead screw 42 to rotate, causing the drive seat 44 to slide along the second guide rail 45, moving the lifting drive module 5 and the second-stage material picking drive module 6 to directly above the outlet of the vibrator 2; then the lifting drive cylinder 51 extends, causing the lifting seat 53 to descend along the third guide rail 52, so that the suction nozzle 64 of the second-stage material picking drive module 6 is close to the motor gear 8 to be picked up.

[0032] When the external vacuum generator is activated, the suction nozzle 64 generates suction force, which attracts the motor gear 8. Then, the lifting drive cylinder 51 retracts, which drives the lifting seat 53 to rise, lifting the motor gear 8 from the outlet of the vibrator 2.

[0033] The horizontal drive module 4 moves again, moving the two-stage material handling drive module 6, which has the motor gear 8 adsorbed, to the target station directly above the gear loading fixture 3. The lifting drive cylinder 51 extends, driving the motor gear 8 to descend to a position close to the sleeve 35.

[0034] The material transfer drive cylinder 61 is activated, causing the movable seat 63 to slide along the fourth guide rail 62, precisely aligning the motor gear 8 with the insertion hole 36 of the sleeve 35. Then, the lifting drive cylinder 51 continues to descend, causing the shaft of the motor gear 8 to be inserted into the insertion hole 36, and the keyway 81 on the shaft precisely engages with the slot 37 at the top of the positioning post 34; the suction nozzle 64 stops the negative pressure and releases the motor gear 8.

[0035] The feeding drive cylinder 32 extends and retracts, causing the fixture base plate 33 to slide along the first guide rail 31, moving the station equipped with the motor gear 8 to the test position, and at the same time moving the next empty station to the material pick-up and unload position. The above steps are repeated to realize continuous motor gear test feeding operation.

[0036] It should be noted that the execution and cessation of the above actions are detected and controlled by photoelectric sensors and controllers, which are existing and well-known technologies and will not be described in detail here.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
