[0023] The following is a further detailed description of the specific implementation methods of the present invention through the description of the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0024] like Figures 1 to 3 As shown, the device for oiling and welding strength testing of welded parts of an automobile window lifter includes a mounting frame 1, a mounting base 2 is provided on the mounting frame 1, a support seat 3 is provided on the mounting base 2, an oiling mechanism is provided on the support seat 3, a positioning mechanism is provided on the mounting base 2, and a driving mechanism is provided at the bottom end of the mounting frame 1.

[0025] like Figures 1 to 3As shown, the automobile window lifter welded parts oiling and welding strength testing device can achieve fixed-point lubrication of the welded parts through the oiling mechanism to ensure good lubrication performance, and can achieve accurate positioning of the welded parts through the positioning mechanism, which is convenient for batch testing of welded parts, can effectively reduce production costs and improve work efficiency.

[0026] like Figure 2 As shown, the oiling mechanism includes an oiling head 5 and an oiling cylinder 4. The support base 3 is an L-shaped structure. The oiling cylinder 4 is provided at the upper end of the support base 3. The lower end of the oiling cylinder 4 is provided with an oiling cylinder piston rod 6. The oiling cylinder piston rod 6 is connected to the oiling cylinder connecting plate. The oiling head 5 is provided on the oiling cylinder connecting plate. The bottom end of the oiling cylinder connecting plate is provided with a pressure plate 7. The two ends of the pressure plate 7 are provided with clamping bolts 8. The oiling mechanism can achieve fixed-point lubrication of the welded parts, and the application position is accurate and the amount of oil applied is consistent. When applied after welding, the lubricating performance does not change, and it can effectively play a lubricating role, thereby ensuring good lubrication performance. The clamping bolts 8 at both ends of the pressure plate 7 can clamp the welded parts.

[0027] like Figure 2 As shown, the positioning mechanism includes a positioning plate 9, a positioning block 12, and a positioning pin 11. A limiting plate 10 is provided on the positioning plate 9. The positioning plate 9 and the limiting plate 10 form a semicircular structure that cooperates with one end of the welded part. The positioning block 12 is provided on the mounting base 2, and the positioning pin 11 is provided on the positioning plate 9. The positioning mechanism can achieve accurate positioning of the welded part, facilitating batch inspection of welded parts. The positioning plate 9, positioning block 12, positioning pin 11, and the mounting block 22 on the swing arm 20 all cooperate with the welded part to achieve accurate positioning of the welded part.

[0028] like Figure 3 As shown, the driving mechanism includes a driving cylinder 13, which is arranged at the bottom end of the mounting base plate 2, and one end of the driving cylinder 13 is connected to a driving cylinder piston rod 14, and the driving cylinder piston rod 14 is connected to a rack 17. The bottom end of the mounting base plate 2 is fixedly connected to a guide rail 16, and a guide plate 15 is provided on the guide rail 16. The guide rail 16 cooperates with the guide plate 15, and one end of the guide rail 16 is provided with a limiting bolt 32 corresponding to the guide plate 15. The driving cylinder piston rod 14, the rack 17, and the guide plate 15 are all fixedly connected, and one end of the rack 17 is provided with a gear 18, and the rack 17 cooperates with the gear 18. A rotating shaft 28 is connected to the rack 17, and the upper end of the rotating shaft 28 passes through the mounting stand 1. The driving mechanism is used to realize the reciprocating motion of the swing arm 20, thereby facilitating the detection of the welding strength of the welded parts. The operation of the driving cylinder 13 drives the driving cylinder piston rod 14 to reciprocate, and then drives the rack 17 to reciprocate on the gear 18. The limit bolt 32 can limit the maximum distance of the movement of the guide plate 15. The reciprocating rotation of the gear 18 causes the rotating shaft 28 to drive the swing arm 20 to rotate. The swing arm 20 can push the balance arm on the welded part to move, and the movement of the balance arm makes the lubricating oil evenly distributed.

[0029] A bearing 19 is provided on the mounting base 2, and a rotating shaft 28 is hingedly connected to the bearing 19. One end of the rotating shaft 28 passes through the bearing 19 and is connected to a swing arm 20. A mounting block 22 is provided at one end of the swing arm 20, which longitudinally corresponds to the oiling head 5. A stopper 21 is provided at the other end of the swing arm 20. The bearing 19 is fixed to the mounting base 2, allowing the rotating shaft 28 to rotate. The reciprocating motion of the swing arm 20 drives the balance arm on the weldment, allowing the lubricating oil to be fully distributed on the weldment and improving lubrication performance.

[0030] A control button 23 is provided at the front of the mounting platform 1, a fan 24 is provided at the top of the mounting platform 1, a process display board 25 is provided on the mounting platform 1, and an electrical control box 27 is provided inside the mounting platform 1.

The process display board 25 can be used to place process instructions to facilitate work. The electrical control box 27 provides a stable power supply for the device.

[0031] A displacement sensor 31 is provided on the positioning plate 9, and a pressure sensor is provided on the oiling head 5. The displacement sensor 31 on the positioning plate 9 can detect whether the set position value meets the standard, and the pressure sensor can detect the change in pressure on the weldment during oiling.

[0032] An oil pressure detector 29 is provided on the support base 3. The oil pressure detector 29 can detect the pressure of the lubricating oil, which facilitates the operation of the staff and the regulation of the lubricating oil pressure.

[0033] The support base 3, the positioning plate 9 and the positioning block 12 are all fixedly connected to the mounting base plate 2. The support base 3, the positioning plate 9 and the bearing 19 provide mounting locations for other parts, and the positioning block 12 realizes the positioning of the welded parts.

[0034] The spacing between the clamping bolts 8 is adapted to the length of the welded parts. This ensures that the welded parts do not move relative to each other during oil filling and weld strength testing, thereby improving the stability of the device during operation.

[0035] like Figures 1 to 3As shown, the device for oiling and welding strength testing of automobile window lifter welded parts is also provided with a socket 26 on the mounting stand 1, which can facilitate the stable power supply when other instruments are used. Casters 30 are provided at the bottom end of the mounting stand 1 to facilitate the movement and transportation of the mounting stand 1. When in use, the welded parts are placed on the positioning plate 9 and the positioning block 12. One end of the welded parts cooperates with the positioning pin 11 on the positioning plate 9. The positioning plate 9 and the limit plate 10 form a semicircular structure to limit the position of the welded parts. The control button 23 is activated, the oiling mechanism is activated, the piston rod of the oiling cylinder 4 is pressed down, and the clamping bolts 8 at both ends of the pressure plate 7 clamp the welded parts. The oiling head 5 corresponds to the mounting block 22 to realize quantitative and fixed-point oiling of the welded parts. After oiling, the drive mechanism is operated, and the reciprocating motion of the piston rod and the matching of the gear 18 and the rack 17 are used to control the oiling mechanism. The combination can make the rotating shaft 28 rotate back and forth within a certain angle, and the rotating shaft 28 drives the swing arm 20 to rotate back and forth within a certain angle. The swing arm 20 can push the parts of the weldment, so that the lubrication applied to the weldment can be evenly distributed, thereby achieving grease application. When the rotation is about to end, the block 21 on the swing arm 20 can block the balance arm on one side of the weldment, and the driving mechanism continues to drive the balance arm on the other side of the weldment to rotate. The displacement sensor 31 can detect whether the set position value meets the standard. The welding strength of the weldment can be judged based on the value obtained by the sensor.

[0036] The device for oiling and welding strength testing welded parts of automobile window regulators can achieve fixed-point lubrication of welded parts through an oiling mechanism to ensure good lubrication performance, and can achieve accurate positioning of welded parts through a positioning mechanism, thereby facilitating batch testing of welded parts, effectively reducing production costs and improving work efficiency.
