Description

Technical Field

[0001] This utility model relates to the field of transmission shaft feeding technology, and in particular to an automatic feeding and positioning device for motor transmission shafts. Background Technology

[0002] With the development of industrial automation, motor drive shafts, as important components of mechanical transmission systems, have increasingly higher requirements for the accuracy of feeding and positioning during their processing and assembly. Traditional manual feeding and positioning methods are inefficient, lack precision, and are prone to workpiece damage or process delays.

[0003] The applicant discovered through a search that a Chinese patent discloses "A feeding device for automated transmission shaft processing, with publication (announcement) number "CN215709230U3". This patent mainly uses two rotating shafts to rotate two rotating wheels, causing a bar to enter the arc-shaped groove on the two rotating wheels. When the rotating wheels rotate again, the bar between the rotating wheels enters the placement mechanism at the bottom, completing the neat arrangement of the bar. However, when the transmission shaft of this device is conveying, it cannot guarantee that the driving end of the transmission shaft is on one side and the driven end is on the other side. The automated equipment has difficulty identifying the direction of the transmission shaft, increasing the risk of downtime and failure. The operator needs to manually flip the transmission shaft, increasing labor intensity and human interference. The transmission shaft with inconsistent direction has poor compatibility and flexibility with the production line. Therefore, we propose an automatic feeding and positioning device for motor transmission shafts. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic feeding and positioning device for motor drive shafts, so as to solve the problems mentioned in the background art, such as the inability to ensure that the drive end of the drive shaft is on one side and the driven end is on the other side during transmission, the difficulty for automated equipment to identify the direction of the drive shaft, the increase in downtime and failure risk, the need for operators to manually flip the drive shaft, the increase in labor intensity and human interference, and the poor compatibility and flexibility of the production line due to the inconsistent direction of the drive shaft.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding and positioning device for a motor drive shaft, comprising a base plate with a conveying structure mounted on its top end. A feeding structure and an adjusting structure are respectively mounted on the conveying structure. The adjusting structure includes a mounting plate and a third motor. The mounting plate rotatably mounts a lead screw via a mounting groove. The motor shaft of the third motor is fixedly connected to the top end of the lead screw. A connecting plate is threaded between the lead screws. The connecting plate is slidably connected to the mounting groove. The connecting plate mounts a mounting box via a rotary cylinder. The mounting box mounts a bidirectional lead screw via a fourth motor. A rubber pad is fixedly mounted on the bidirectional lead screw via a slider and a clamping plate.

[0006] As a preferred embodiment, the conveying structure includes a fixed frame and rollers. The fixed frame is fixedly installed on the top of the base plate, and the rollers are rotatably installed at both ends inside the fixed frame. The rollers are connected by a conveyor belt. A first motor is fixedly installed on the outside of the fixed frame, and the motor shaft of the first motor is fixedly connected to one end of the rollers.

[0007] As a preferred embodiment, the feeding structure includes a storage box, a connecting frame, and a support. The storage box is fixedly installed on the top of the fixed frame via the connecting frame, and a discharge chute is provided at the bottom of the storage box.

[0008] As a preferred embodiment, a rotating shaft is rotatably installed at the bottom of the storage bin, a rotating cylinder is fixedly installed on the rotating shaft, an arc-shaped groove is provided on the rotating cylinder, a second motor is fixedly installed on the outer wall of the storage bin, the motor shaft of the second motor is fixedly connected to one end of the rotating shaft, and the bracket is symmetrically fixedly installed on the conveyor belt.

[0009] As a preferred embodiment, the mounting plate is fixedly installed on the top of the mounting frame, the mounting groove is formed inside the mounting plate, the lead screw is rotatably installed in the mounting groove, and the third motor is fixedly installed on the top of the mounting plate.

[0010] As a preferred embodiment, the rotary cylinder is fixedly mounted on the connecting plate, the mounting box is fixedly mounted on the rotating end of the rotary cylinder, the bidirectional lead screw is rotatably mounted inside the mounting box, the fourth motor is fixedly mounted on the outside of the mounting box, the motor shaft of the fourth motor is fixedly connected to one end of the bidirectional lead screw, the slider is threadedly mounted on the bidirectional lead screw, the slider is slidably connected to the inner wall of the mounting box, the clamping plate is fixedly mounted on the bottom end of the slider, and the rubber pad is fixedly mounted on one side of the clamping plate.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the set adjustment structure, the lead screw drives the mounting box to rise and fall through the connecting plate and the rotary cylinder. The bidirectional lead screw in the mounting box drives the clamping plate to clamp the drive shaft through the slider. The rotary cylinder drives the mounting box to rotate, thereby rotating the drive shaft on the bracket. This makes the driving end of different drive shafts on one side and the driven end on the other side, reducing manual flipping or manual centering operations, improving production efficiency, ensuring that the automated equipment can accurately identify and operate the drive shaft, reducing downtime or failures caused by inconsistent directions, ensuring assembly accuracy, avoiding rework or line stoppages, and improving assembly efficiency.

[0013] 2. Through the feeding structure, the second motor drives the rotating drum to rotate via the rotating shaft. The rotating drum is equipped with an arc-shaped groove to accommodate one drive shaft, so that the drive shafts are placed one by one on the support on the conveyor belt. This avoids jamming or chaos caused by multiple drive shafts falling at the same time, ensuring that only one drive shaft is conveyed at a time, improving the reliability and efficiency of feeding. No manual intervention is required, reducing human involvement and increasing the degree of automation. Attached Figure Description

[0024] The feeding structure 3 includes a storage box 31 and a connecting frame 32. The storage box 31 is fixedly installed on the top of the fixed frame 21 through the connecting frame 32.

Several brackets 37 are symmetrically fixedly installed on the conveyor belt 23.

[0025] Specifically, through the feeding structure 3, the second motor 36 drives the rotating drum 35 to rotate via the rotating shaft 34. The rotating drum 35 is provided with an arc-shaped groove to accommodate one drive shaft, so that the drive shafts are placed one by one on the bracket 37 on the conveyor belt 23, avoiding jamming or chaos caused by multiple drive shafts falling at the same time, ensuring that only one drive shaft is conveyed at a time, improving the reliability and efficiency of feeding, eliminating the need for manual intervention, reducing human involvement, and improving the degree of automation.

[0026] Example 2:

[0027] Please see the appendix Figure 5 and attached Figure 6The adjusting structure 4 includes a mounting plate 401, which is fixedly mounted on the top of the fixed frame 21 and on one side of the storage box 31. A mounting groove 402 is formed in the mounting plate 401, and a lead screw 403 is rotatably mounted in the mounting groove 402. A third motor 404 is fixedly mounted on the top of the mounting plate 401, and the motor shaft of the third motor 404 is fixedly connected to the top of the lead screw 403. A connecting plate 405 is threadedly mounted between the lead screws 403, and the connecting plate 405 is slidably connected to the mounting groove 402. A rotary screw is fixedly mounted on the connecting plate 405. Rotary cylinder 406, with mounting box 407 fixedly installed at the rotating end of rotary cylinder 406.

The motor shaft of fourth motor 409 is fixedly connected to one end of bidirectional lead screw 408. Slider 410 is threaded onto bidirectional lead screw 408. Slider 410 is slidably connected to the inner wall of mounting box 407. Clamping plate 411 is fixedly installed at the bottom end of slider 410. Rubber pad 412 is fixedly installed on one side of clamping plate 411.

[0028] Specifically, by adjusting structure 4, lead screw 403 and rotary cylinder 406 drive mounting box 407 to rise and rotate. Bidirectional lead screw 408 drives clamping plate 411 to clamp the drive shaft through slider 410, so as to unify the direction of drive end and driven end of drive shaft, reduce manual flipping, improve production efficiency, ensure accurate operation of automated equipment, avoid downtime or rework due to incorrect direction, and optimize assembly efficiency.

[0029] The working principle of this utility model is as follows: This utility model is an automatic feeding and positioning device for a motor drive shaft. The drive shaft is placed in the storage box 31, and the first motor 24 is started. The motor shaft of the first motor 24 drives the roller shaft 22 to rotate, and the roller shaft 22 drives the conveyor belt 23 to drive the transmission. The conveyor belt 23 drives the support 37 to move. The first motor 24 can rotate intermittently each time. The second motor 36 is started, and the motor shaft of the second motor 36 drives the rotating shaft 34 to rotate. The rotating shaft 34 drives the rotating drum 35 to rotate. The drive shaft in the storage box 31 enters the arc groove in the rotating drum 35. The rotating drum 35 drives the drive shaft to rotate. When the drive shaft rotates to the top of the discharge trough 33, the support 37 moves to the bottom of the discharge trough 33. The drive shaft falls down from the discharge trough 33 onto the support 37. The support 37 supports the drive shaft, and the conveyor belt 23 transports the drive shaft.

[0030] The drive shaft has a drive end and a driven end at its two ends. Since the drive shaft is placed arbitrarily in the storage bin 31, the drive end and driven end may both be on one side. When the drive ends and driven ends of different drive shafts on the bracket 37 are on one side, the third motor 404 is started. The motor shaft of the third motor 404 drives the lead screw 403 to rotate, which in turn drives the connecting plate 405 to slide downwards. Then, the fourth motor 409 is started, and its motor shaft drives the bidirectional lead screw 408 to rotate. The bidirectional lead screw 408 controls the movement of the slider 410, which in turn moves the clamping plate 411. As the rubber pad 412 moves, the clamping plate 411 clamps both ends of the drive shaft through the rubber pad 412. Then, the connecting plate 405 is controlled to slide upward, causing the drive shaft to leave the bracket 37. The rotary cylinder 406 is activated, and the rotating part of the rotary cylinder 406 drives the mounting box 407 to rotate. The mounting box 407 drives the drive shaft to rotate, and the connecting plate 405 is controlled to descend, so that the drive shaft is placed back on the bracket 37. The clamping plate 411 and the rubber pad 412 are no longer clamping the drive shaft, thereby distinguishing the driving end and the driven end of the drive shaft, so that the driving end and the driven end are on one side and the driven end and the driven end are on the other side.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
