Description

Technical Field

[0001] This utility model relates to the field of differential oil seal and oiling technology, specifically an oil seal press for a new energy electric drive assembly line. Background Technology

[0002] In new energy vehicles, the differential functions similarly to that in traditional gasoline vehicles, its core function being to adjust the speed difference between the left and right drive wheels, ensuring the vehicle's stability and safety under various driving conditions. During the assembly process of a new energy vehicle differential assembly line, it is necessary to first automatically apply oil to the oil seal pressing positions on both sides of the differential, and then press the oil seals onto the half-shaft holes on both sides of the differential. Currently, differential oiling and oil seal pressing require separate equipment, resulting in long assembly times and an inability to effectively shorten the cycle time. Furthermore, the separate equipment occupies a large area, leading to low site utilization. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned shortcomings by integrating automatic oiling and oil sealing into a single device, effectively shortening the cycle time, reducing the equipment's footprint, and increasing site utilization.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A new energy electric drive assembly line oil seal press includes a frame, a conveyor line passing through the frame, a tray that slides along the conveyor line, and an oiling assembly and an oil seal pressing assembly arranged sequentially on the frame along the conveyor line's conveying direction. The conveyor line is used to sequentially send the differential housing to the oiling assembly and the oil seal pressing assembly via the tray. The oil seal pressing assembly is used to press the oil seal, and the oiling assembly is used to apply oil.

[0006] Furthermore, the oil seal pressing assembly includes a positioning mechanism and a pressing mechanism. The positioning mechanism is used to position and clamp the differential housing on the tray, and the pressing mechanism is used to press the oil seal onto the differential housing.

[0007] Furthermore, an RFID electronic chip is installed at the bottom of the tray, and an RFID reader is installed on the conveyor mounting frame below the frame.

The positioning mechanism includes a positioning block, a positioning cylinder for driving the positioning block to rise or fall, a centering cylinder fixed on the conveyor mounting frame, a pressure seat located directly above the centering cylinder, a balancing cylinder for driving the pressure seat to rise or fall, a lifting frame for mounting the balancing cylinder, and a Z-axis servo cylinder for driving the lifting frame to rise or fall along the frame. The piston rod of the centering cylinder extends vertically upward and is connected to a centering rod. The Z-axis servo cylinder is mounted on the frame.

[0008] Furthermore, the pressing mechanism includes a left pressing frame and a right pressing frame, a left press mounted on the left pressing frame, a left press head located at the output end of the left press, a right press mounted on the right pressing frame, and a right press head located at the output end of the right press, with the left press head and the right press head facing each other.

[0009] Furthermore, the pressing mechanism also includes front and rear slides that are slidably connected to the lifting frame, and a Y-axis servo electric cylinder that drives the front and rear slides to slide back and forth. The left pressing frame and the right pressing frame are mounted on the front and rear slides, and the Y-axis servo electric cylinder is fixed on the lifting frame.

[0010] Furthermore, the oiling assembly includes a second positioning mechanism and an oiling mechanism. The second positioning mechanism is used to position the differential, and the oiling mechanism is used to apply oil to the differential.

Detailed Implementation

[0025] like Figure 1-8 As shown, the oil seal press of the new energy electric drive assembly line includes a frame 1, a conveyor line 2 passing through the frame 1, a tray that slides along the conveyor line 2, and an oiling assembly 4 and an oil seal pressing assembly 3 arranged sequentially on the frame 1 along the conveying direction of the conveyor line 2. The conveyor line 2 is used to send the differential housing sequentially to the oiling assembly 4 and the oil seal pressing assembly 3 through the tray. The oil seal pressing assembly 3 is used to press the oil seal, and the oiling assembly 4 is used to apply oil.

[0026] In use, conveyor line 2 first sends the differential housing on the tray to the oiling assembly 4. The oiling assembly 4 applies oil to the differential housing. After the oiling is completed, conveyor line 2 sends the differential housing on the tray to the oil seal pressing assembly 3. The oil seal pressing assembly 3 then presses the oil seal onto the differential housing. This utility model can integrate automatic oiling and oil seal pressing into one device, effectively shortening the cycle time, reducing the equipment's footprint, and increasing the site utilization rate.

[0027] like Figure 1-8 As shown, the oil seal pressing assembly 3 includes a positioning mechanism and a pressing mechanism. The positioning mechanism is used to position and clamp the differential housing on the tray, and the pressing mechanism is used to press the oil seal onto the differential housing. In this embodiment, the positioning mechanism is used to position and clamp the differential housing. After manually feeding two oil seals, the pressing mechanism is used to press the oil seal onto the differential housing.

[0028] like Figure 1-8As shown, an RFID electronic chip is provided on the side of the tray, and an RFID reader 5 is provided on the mounting frame of the conveyor line 2 below the frame 1. The RFID reader 5 is compatible with the RFID electronic chip, and a connection hole is vertically provided on the tray. The positioning mechanism includes a positioning block 311, a positioning cylinder 312 for driving the positioning block 311 to rise or fall, a centering cylinder 313 fixed on the mounting frame of the conveyor line 2, a pressure seat 314 located directly above the centering cylinder 313, a balancing cylinder 315 for driving the pressure seat 314 to rise or fall, a lifting frame 316 for mounting the balancing cylinder 315, and a Z-axis servo cylinder 317 for driving the lifting frame 316 to rise or fall along the frame 1. The piston rod of the centering cylinder 313 is vertically oriented towards... The upper extension drive is connected to the centering rod 318, and the Z-axis servo cylinder 317 is mounted on the frame 1. In this embodiment, during the pallet transfer process driven by the conveyor line 2, when the RFID reader 5 identifies the RFID electronic tag, the positioning cylinder 312 drives the positioning stop block 311 to rise, so that the front end of the pallet abuts against the positioning stop block 311. The conveyor line 2 stops conveying, and the piston rod head of the centering cylinder 313 extends vertically upward, so that the top of the centering rod 318 passes through the connecting hole and extends into the drive shaft hole of the differential housing to position the differential housing. At the same time, the Z-axis servo cylinder 317 drives the lifting frame 316 to descend, and the balancing cylinder 315 drives the pressure seat 314 to move down, pressing the differential housing onto the pallet to press and position the differential housing. After the oil seal is pressed, the positioning cylinder 312 drives the stop block to descend, and the conveyor line 2 drives the pallet to continue to move.

[0029] like Figure 1-8 As shown, the pressing mechanism includes a left pressing frame 321 and a right pressing frame 322. A left press 323 is mounted on the left pressing frame 321, a left press head 324 is located at the output end of the left press 323, a right press 325 is mounted on the right pressing frame 322, and a right press head 326 is located at the output end of the right press 325. The left press head 324 and the right press head 326 are positioned opposite each other. In this embodiment, when the Z-axis servo cylinder 317 drives the lifting frame 316 to descend, the left press head 324 and the right press head 326 are positioned opposite the two half-shaft holes on the differential housing. Since the positioning mechanism has already clamped the differential housing, after manually inserting the two oil seals into the half-shaft holes, the left press 323 drives the left press head 324 to move to the right, and the right press 325 drives the right press head 326 to move to the left, thus pressing and maintaining the pressure of the two oil seals.

[0030] like Figure 1-8As shown, the pressing mechanism also includes front and rear slides 327 slidably connected to the lifting frame 316, and a Y-axis servo cylinder 328 driven by the output end to slide the front and rear slides 327 back and forth. The left pressing frame 321 and the right pressing frame 322 are mounted on the front and rear slides 327, and the Y-axis servo cylinder 328 is fixed on the lifting frame 316. In this embodiment, since the half-shaft hole positions of different models of differential housings are different, the front and rear slides 327 are driven to slide back and forth by the Y-axis servo cylinder 328 to adjust the front and rear positions of the left pressing head 324 and the right pressing head 326. The lifting frame 316 is driven to rise or fall by the Z-axis servo cylinder 317 to adjust the up and down positions of the left pressing head 324 and the right pressing head 326 so that they are aligned with the half-shaft holes of the differential housing. This makes it compatible with different models of differential housing assembly lines and has better applicability.

[0031] like Figure 1-8 As shown, the oiling assembly 4 includes a positioning mechanism two and an oiling mechanism. The positioning mechanism two is used to position the differential, and the oiling mechanism is used to apply oil to the differential. In this embodiment, the positioning mechanism two positions the differential externally, and the oiling mechanism applies oil to the positioned differential.

[0032] like Figure 1-8 As shown, the second positioning mechanism includes a second positioning block 411 and a second positioning cylinder 412 for driving the second positioning block 411 to rise or fall. The second positioning cylinder 412 is mounted on the mounting frame of the conveyor line 2. In this embodiment, during the process of driving the pallet closer to the oiling component 4 through the conveyor line 2, the second positioning block 411 is in a rising state. When the front end of the pallet abuts against the second positioning block 411, the conveyor line 2 stops conveying, and the oiling mechanism applies oil to the positioned differential.

[0033] like Figure 1-8As shown, the oiling mechanism includes a Y-axis frame 421 positioned above the conveyor line 2, two booms 422 positioned below the Y-axis frame 421, an oiler 423 mounted near the bottom of the booms 422, a Y-axis cylinder 424 for driving the booms 422 closer to or further away from the middle of the Y-axis frame 421, an X-axis cylinder 425 for driving the Y-axis frame 421 to move left or right, an X-axis seat 426 for mounting the X-axis cylinder 425, and a Z-axis cylinder 427 for driving the X-axis seat 426 to rise or fall. The Z-axis cylinder 427 is fixed to the frame 1. 4. Mounted on the Y-axis frame 421, an oil box 428 is provided below the oiler 423, and the oil box 428 is fixed on the boom 422. The spray ends of the two oilers 423 are positioned opposite each other. In this embodiment, the boom 422 is driven to move closer to or further away from the middle of the Y-axis frame 421 by the Y-axis cylinder 424 to adjust the distance between the two oilers 423. The Y-axis frame 421 is driven to move left and right by the X-axis cylinder 425 to adjust the left and right oiling position of the oiler 423. The X-axis seat 426 is driven to rise or fall by the Z-axis cylinder 427 to adjust the oiling height of the oiler 423, making it suitable for oiling different models of products and improving its applicability.

[0034] like Figure 1-8 As shown, it also includes a cover 6 mounted on the frame 1, and an electrical control cabinet 7 located on the rear side of the cover 6. The oil seal pressing assembly 3 and the oiling assembly 4 are both electrically connected to the electrical control cabinet 7. In this embodiment, the cover 6 can provide a certain dustproof effect, and the electrical control cabinet 7 can control the oil seal pressing assembly 3 and the oiling assembly 4.
