Description

Technical Field

[0001] The utility model relates to the field of automobile seat motor assembly, in particular to a riveting device for automobile seat motor parts. Background Art

[0002] The worm gear and gearbox cover are two critical components in automotive seat motors. Both require riveting during processing: the center bracket must be pressed into the worm gear, and the bushing must be pressed into the gearbox cover. Conventional presses typically use a manual press for the center bracket, and a pneumatic press for the bushing. These drawbacks are as follows: 1. Due to the high demand for both components, multiple devices are required to press them in separately, taking up space in the factory; 2. Pneumatic presses lack protective devices, making them susceptible to injury during operation; and 3. Manual presses are time-consuming and labor-intensive, hindering overall motor assembly efficiency. Summary of the Invention

[0003] In view of the deficiencies of the existing technology, the present invention has developed a riveting device for automobile seat motor parts. The technical solution adopted by the present invention is: a riveting device for automobile seat motor parts, characterized in that it includes a cabinet 1, a workbench 4, a frame 6, a base 11, a hydraulic pump 27 and a PLC; the workbench 4 is arranged in the cabinet 1; the frame 6 and the base 11 are fixedly connected; the base 11 is fixedly arranged on the workbench 4; the first hydraulic cylinder 5 and the second hydraulic cylinder 14 are respectively fixedly arranged on the frame 6, and their piston rods respectively pass through the upper part of the frame 6; the first guide rail 12 and the second guide rail 20 are respectively fixedly connected to the rear part of the frame 6; the first upper mold 7 and the second upper mold 16 are respectively connected to the piston rods of the first hydraulic cylinder 5 and the second hydraulic cylinder 14, and the two are respectively slidably connected to the first guide rail 12 and the second guide rail 20; the first pressing head 13 and the second pressing head 19 are respectively slidable with the first upper mold 7 and the second upper mold 16 Disassembly connection; the first lower mold 10 and the second lower mold 21 are respectively fixedly arranged on the base 11 and are respectively placed directly below the first upper mold 7 and the second upper mold 16; the first proximity switch 9 and the second proximity switch 18 are respectively detachably connected to the left and right sides of the frame 6; the first pin 8 and the second pin 17 are respectively arranged on the first upper mold 7 and the second upper mold 16, and correspond to the first proximity switch 9 and the second proximity switch 18 respectively; the buzzer 2, the grating 3, and the touch screen 15 are respectively fixedly arranged on the cabinet 1; the two-hand switch button 22 is fixedly arranged on the workbench 4; the first hydraulic cylinder 5 and the second hydraulic cylinder 14 are respectively connected to the hydraulic pump 27 pipeline; the buzzer 2, the grating 3, the first proximity switch 9, the touch screen 15, the second proximity switch 18 and the two-hand switch button 22 are respectively electrically connected to the PLC.

[0004] The benefits of the present invention are as follows: 1. Since two hydraulic cylinders are used to press the center bracket and the bushing at the same workstation, the waste of factory space caused by operating multiple machines separately is avoided. Two parts can be processed at the same workstation at the same time, which avoids the low efficiency and slow speed of manual processing that hinders the overall assembly of the motor; 2. Since a grating is added, it is effectively avoided that workers are injured in the event of misoperation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0009] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0010] like Figure 1The utility model comprises: a cabinet 1, a workbench 4, a frame 6, a base 11, a hydraulic pump 27 and a PLC; the workbench 4 is arranged in the cabinet 1; the frame 6 and the base 11 are fixedly connected; the base 11 is fixedly arranged on the workbench 4; the first hydraulic cylinder 5 and the second hydraulic cylinder 14 are respectively fixedly arranged on the frame 6, and their piston rods respectively pass through the upper part of the frame 6; the first guide rail 12 and the second guide rail 20 are respectively fixedly connected to the rear part of the frame 6; the first upper die 7 and the second upper die 16 are respectively connected to the piston rods of the first hydraulic cylinder 5 and the second hydraulic cylinder 14, and the two are respectively slidably connected to the first guide rail 12 and the second guide rail 20; the first pressure head 13 and the second pressure head 19 are respectively detachably connected to the first upper die 7 and the second upper die 16; the first lower die 10, the first lower die 11 and the second lower die 12 are respectively connected to the first upper die 7 and the second upper die 16; The two lower molds 21 are respectively fixed on the base 11 and are placed directly below the first upper mold 7 and the second upper mold 16; the first proximity switch 9 and the second proximity switch 18 are respectively detachably connected to the left and right sides of the frame 6; the first pin 8 and the second pin 17 are respectively provided on the first upper mold 7 and the second upper mold 16, and correspond to the first proximity switch 9 and the second proximity switch 18 respectively; the buzzer 2, the grating 3, and the touch screen 15 are respectively fixed on the cabinet 1; the two-hand switch button 22 is fixed on the workbench 4; the first hydraulic cylinder 5 and the second hydraulic cylinder 14 are respectively connected to the hydraulic pump 27 pipeline; the buzzer 2, the grating 3, the first proximity switch 9, the touch screen 15, the second proximity switch 18 and the two-hand switch button 22 are respectively electrically connected to the PLC.

[0011] When doing specific operations, such as Figure 2 As shown, the worker places the worm gear 26 on the first lower die 10 to complete the positioning of the worm gear 26; the worker clamps the center bracket 23 on the first pressure head 13, and the clamping force between the two is not large. The above steps complete the pre-installation of the center bracket and the worm gear to ensure that the components are concentric; the worker places the gear box cover 25 on the second lower die 21 to complete the positioning of the second lower die 21; the worker places the bushing 24 in the through hole matched with it on the gear box cover 25. The above steps complete the pre-installation of the gear box cover and the bushing to ensure that the components are concentric; then, the worker operates the touch screen 15 to select the simultaneous processing of the worm gear as needed. The following is an example of processing a worm wheel and a gear box cover at the same time: after the worker completes the pre-assembly of the worm wheel and the gear box cover, he should withdraw his hands from the cabinet 1 and press the two-hand switch button 22 with both hands to start the device. When the grating 3 detects that there is no object blocking it, it sends a signal to the PLC. The PLC determines that the worker's hands are out of the cabinet. If there is still foreign matter remaining in the detection range of the grating 3, the worker presses the two-hand switch button 22, and the grating 3 sends a signal to the PLC. The PLC controls the buzzer 2 to sound an alarm, prompting the worker to check for foreign matter. Figure 3 As shown, after the grating 3 is detected to be normal, the PLC controls the hydraulic pump 27 to work, and the hydraulic pump 27 pressurizes the first hydraulic cylinder 5 and the second hydraulic cylinder 14 at the same time. The piston rods of both move downward, respectively driving the first upper mold 7 and the second upper mold 16 to move downward. The first upper mold 7 drives the first pressing head 13 to press the center bracket 23 into the worm gear 26. The clamping force between the center bracket 23 and the first pressing head 13 is not large, but the clamping force between the center bracket 23 and the worm gear 26 is relatively large; the second pressing head 19 presses the bushing 24 into the gear box cover 25. When the first pin rod 8 moves to be detected by the first proximity switch 9, the first proximity switch 9 sends a signal to the PLC, and the PLC determines that the first pressure head 13 has been pressed into place. The PLC controls the hydraulic pump 27 to raise the piston rod of the first hydraulic cylinder 5. Similarly, when the second pin rod 17 moves to be detected by the second proximity switch 18, the second proximity switch 18 sends a signal to the PLC, and the PLC retracts the piston rod of the second hydraulic cylinder 14, completing the processing operation of the two components. The worker can then remove the two components.

[0012] The pressing depth of the first pressing head 13 and the second pressing head 19 can be adjusted by adjusting the height of the first proximity switch 9 and the second proximity switch 18 .

[0013] The hydraulic cylinder and the hydraulic pump used in the present invention are both commercially available products, and their connection and control methods are prior arts well known to those skilled in the art.

[0014] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
