Description

Technical Field

[0002] When installing gears onto the motor output shaft, a press is often used to apply pressure to ensure a secure fit and proper operation, as the gears typically have a tight fit with the shaft. However, traditional presses often require frequent manual handling during gear installation. Since the gear and motor shaft positioning accuracy needs to be controlled within 0.1mm, relying on manual visual alignment and adjustment makes it difficult to guarantee precision. Deviations can lead to poor gear meshing, increased noise, and even shortened motor life. Furthermore, manual loading and unloading have a low tolerance for error, increasing the probability of incorrect, missing, or mixed installations. This also poses significant safety hazards, as carelessness can result in accidents such as crushing hands. In addition, poor operator stability makes it difficult to ensure consistency in each pressing process, thus affecting the quality of the finished product. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Please refer to Figure 1This utility model provides an automatic loading and unloading servo press, including a frame 1, a tray positioning assembly 2 for positioning the motor, a gear feeding device 3 for feeding the gear, a robot loading and unloading clamping device 4 for clamping the motor and gear, a servo pressure device 5 for pressing the gear onto the motor output shaft, a stamping positioning device 6 for pre-positioning the gear on the motor output shaft, and a conveying device 7 for moving the stamping positioning device 6 to below the servo pressure device 5, etc. The components of this embodiment will be described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 and Figure 2 As shown, the pallet positioning component 2, gear feeding device 3, robot loading / unloading clamping device 4, servo pressure device 5, and conveying device 7 can all be installed on the top surface of the frame 1. The pallet positioning component 2 and gear feeding device 3 are located on both sides of the conveying device 7, the robot loading / unloading clamping device 4 is located on the loading end side of the conveying device 7, and the servo pressure device 5 is fixedly installed above the pressing end of the conveying device 7 along the conveying direction of the stamping positioning device 6. The output part of the robot loading / unloading clamping device 4 can move back and forth above the pallet positioning component 2, gear feeding device 3, and conveying device 7.

[0031] like Figure 3 As shown, the pallet positioning assembly 2 may include a support base plate 21, support rods 22, a pallet base plate 23, and a pallet 24. The pallet base plate 23 is fixedly mounted on the support base plate 21 by four support rods 22. The pallet 24 is placed on the pallet base plate 23. Limiting blocks 231 for limiting the position of the pallet 24 are respectively provided at the four corners of the top of the pallet base plate 23. The top of the pallet 24 has several slots arranged in an array for storing the motor.

[0032] The tray 24 can accommodate motors without gears and motors with gears, ensuring that the motor storage slot is fixed and facilitating accurate motor loading and unloading by the robot's clamping device 4.

[0033] like Figure 4 As shown, the gear feeding device 3 may include a vibratory feeder 31, a gear feeding track 32, and a direct vibratory feeder 33. The discharge port of the vibratory feeder 31 is connected to the feed end of the gear feeding track 32, and the direct vibratory feeder 33 is located at the bottom of the gear feeding track 32. The vibration of the vibratory feeder 31 causes the gears to be arranged in an orderly manner and enter the gear feeding track 32 from their discharge ports. The direct vibratory feeder 33 provides power for the movement of the gears within the track, enabling the gears to be continuously fed forward. This achieves automatic feeding of individual gears, improves production efficiency, and reduces manual intervention.

[0034] like Figure 5As shown, the robot loading and unloading gripping device 4 may include a multi-axis robot 41 and a robot gripper 42. Preferably, the multi-axis robot 41 may be a six-axis robot commonly found on the market, and the robot gripper 42 is rotatably mounted downwards on the sixth axis of the six-axis robot.

[0035] Preferably, the robot gripper 42 may include a gripper connecting plate 421, a gear gripper, and a motor gripper. The gripper connecting plate 421 is fixedly connected to the bearing of the end axis of the multi-axis robot 41, and the gear gripper and the motor gripper are respectively disposed downward at both ends of the gripper connecting plate 421.

[0036] Specifically, such as Figure 6 As shown, the gear clamp can be configured as a first gripper cylinder 431 for clamping gears, and the two grippers of the first gripper cylinder 431 are respectively provided with contour clamps 432;

[0037] like Figure 7 As shown, the motor clamp may include a second rotary cylinder 441 and a second gripper cylinder 442 for clamping the motor.

The second rotary cylinder 441 can drive the second gripper cylinder 442 to rotate. The two grippers of the second gripper cylinder 442 are respectively provided with motor clamps 443 with anti-slip textures at the ends.

[0038] In practice, the first gripper cylinder 431 clamps the gear through the contour clamp 432, and the second rotary cylinder 441 drives the second gripper cylinder 442 to rotate to a suitable angle. The second gripper cylinder 442 clamps the motor through the motor clamp 443, and then the motor and gear are moved to the loading end stamping and positioning device 6 located on the conveying device 7. The robot loading and unloading device 4 replaces manual loading and unloading, and the repeatability positioning accuracy can reach 0.015mm.

[0039] like Figure 8 As shown, the conveying device 7 may include a support frame 71, a slide rail 72, a slider 73, a linear module 74, and a stamping base plate 75. The slide rail 72 and the linear module 74 are respectively installed parallel to each other along the length direction of the support frame 71 on the top surface of the support frame 71. The slider 73 is slidably connected to the slide rail 72. One side of the stamping base plate 75 is fixedly connected to the output part of the linear module 74, and the other side of the stamping base plate 75 is fixedly connected to the top of the slider 73 through a pad 751.

[0040] like Figure 9As shown, the stamping positioning device 6 may include a slide lifting cylinder 61, a positioning block 62, a positioning pin 63, and a first rotary cylinder 64. The slide lifting cylinder 61 is vertically installed on the top of the stamping base plate 75. The first rotary cylinder 64 is horizontally positioned above the stamping base plate 75 via an L-shaped plate. The positioning block 62 consists of two blocks, which are combined at the middle to form a locking position 60 for positioning the motor. One of the positioning blocks 62 has a notch 621 at the top for the robot's loading and unloading device to drive the motor to load and unload materials. The positioning pin 63 is vertically fixed between the positioning block 62 and the first rotary cylinder 64. The first output rotor 641 of the first rotary cylinder 64 has a through hole 642 in the middle for the positioning pin 63 to pass through. The end of the first output rotor 641 has a positioning hole 643 for gear positioning to fit onto the motor output shaft.

[0041] Among them, the stamping positioning device 6 can ensure the accurate position of the gear before pressing, reduce the deviation during gear pressing, and improve the assembly accuracy. The positioning block 62 and the positioning pin 63 can limit the position of their respective motors and gears. The conveying device 7 realizes automated workstation conversion, improves production efficiency, and has high displacement accuracy.

[0042] like Figure 10 As shown, the servo pressure device 5 may include a press base plate 51, a press top plate 52, a support column 53, an electric cylinder 54, a coupling 55, and a connecting pressure head 56. The press top plate 52 is fixedly connected to the press base plate 51 above the press by four support columns 53. The electric cylinder 54 is set downward on the press top plate 52 and its output shaft passes through the press top plate 52. The connecting pressure head 56 is connected to the output shaft of the electric cylinder 54 through the coupling 55. The electric cylinder 54 can drive the connecting pressure head 56 to move up and down.

[0043] like Figure 11 As shown, the servo pressure device 5 may also include a press cover 57, which covers the outside of the electric cylinder 54. The bottom front of the press cover 57 has a front opening 571 for the conveying device 7 to pass through. The press cover 57 is provided with several control buttons 572. Cooling fans 573 connected to the outside are installed on the inner walls of both sides of the press cover 57.

[0044] In this implementation, an electric cylinder 54 is used as the press to provide the required pressing force. The servo control pressing distance has high accuracy, and the repeatability can be controlled within ±0.01mm. According to the pressing process requirements, the stability and consistency of product quality can be guaranteed.

[0045] Furthermore, the press housing 57 protects the operator's safety with a high safety factor, and the cooling fan 573 reduces the temperature of the equipment during operation.

[0046] The working principle of this utility model is as follows:

[0047] First, workers place a pallet 24 filled with unassembled gears onto the pallet base 23. Then, the gear feeding device 3 is activated, and the vibratory feeder 31 and linear vibratory feeder 33 evenly transport the gears onto the feeding track 32 for automated gear loading. The second gripper cylinder 442 of the robot's loading / unloading device 4, via the second rotary cylinder 441, adjusts to a suitable angle and grips the unassembled motors on the pallet 24, placing them in the slot of the stamping positioning device 6 to achieve automatic motor loading. Next, the first gripper cylinder 431, holding the gears, rotates them above the stamping positioning device 6. The first rotary cylinder 64 drives the through hole 642 to rotate above the positioning pin 63 and... The slide lifting cylinder 61 drives it to descend. At this time, the positioning hole 643 is also located above the motor output shaft. Then, the first gripper cylinder 431 releases the gear and allows it to pass through the positioning hole 643 and be pre-fitted onto the motor output shaft. Then, the conveying device 7 moves the stamping positioning device 6 to below the servo pressure device 5. The electric cylinder 54 drives the connecting pressure head 56 to move downward to press the gear onto the motor output shaft. After pressing, the slide lifting cylinder 61 drives the first rotary cylinder 64 to move upward, and at the same time, the first output rotating head 641 rotates and disengages from the positioning pin 63. Then, the conveying device 7 sends the stamping positioning device 6 out. Finally, the second gripper cylinder 442 clamps the motor with the assembled gear. Figure 12 (As shown) The material is transferred to the slot of pallet 24 for unloading, thus completing one automated pressing operation.

[0048] In summary, this utility model can realize a series of automated operations such as automated loading and unloading, automated pre-positioning, automated transfer and automated pressing of motors and gears, replacing manual operation, significantly improving production efficiency and repeatability accuracy, avoiding problems such as misalignment, omission and confusion, with a high safety factor, ensuring the stability of product quality, and meeting the needs of large-scale production of enterprises.
