[0006] By adopting the above technical scheme, the pulley is first oiled by the oiling mechanism, and then the oiled pulley is assembled with the rivet, and then the pulley equipped with the rivet is assembled at the riveting position at one end of the automobile part, and the assembled automobile part is placed on the mounting block and the limit frame, so that the riveted end of the automobile part is placed on the mounting block, and the other end is correspondingly clamped in the notch of the limit frame, and then the limit plate is installed on the top of the riveting position of the automobile part, and finally the parts on the mounting block are riveted as a whole by the riveting equipment to realize the assembly of the pulley, after the pulley assembly at one end of the automobile part is completed, the same assembly work is performed again on the other end of the automobile part, and then the assembly work of the pulleys at both ends of the automobile part is completed, and the detection control mechanism set can detect whether the oiling mechanism is working and control the riveting device, when the detection control mechanism detects that the oiling mechanism is working, the riveting device can work normally, when the detection control mechanism does not detect that the oiling mechanism is working, the riveting device does not work, thereby reducing the occurrence of the pulley being assembled without oiling and reducing the defective rate.

When the bottom surface of the casing contacts the top surface of the support plate, the nozzle on the oil spray pipe extends through the through hole to the top surface of the casing. At this time, the oil delivery component transports lubricating oil into the oil spray pipe and sprays the lubricating oil on the pulley through the nozzle, thereby realizing the oiling of the pulley.

[0031] like Figure 3 and Figure 4 As shown, the top surface of the base 1 is provided with an oiling mechanism 5 for oiling the pulley, and the oiling mechanism 5 includes a support plate 51, a casing 52, an oil injection pipe 53 and an oil delivery assembly 54. The support plate 51 is fixedly connected to the top surface of the base 1, and a column 55 is coaxially fixedly connected to the top surface of the support plate 51. The casing 52 is sleeved on the top of the column 55, and the casing 52 and the outer wall of the column 55 are slidably matched. An annular plate 56 is coaxially fixedly connected to the outside of the casing 52, and a spring 57 surrounding the outside of the column 55 is fixedly connected to the bottom surface of the annular plate 56, and the bottom end of the spring 57 is fixedly connected to the support plate 51 is fixedly connected to the top surface of the casing 52, a plurality of through holes 521 are opened on the top surface of the casing 52, a rubber pad is fixedly connected to the inner side wall of each through hole 521, a cross opening 523 is opened on the rubber pad, an oil injection pipe 53 is fixedly connected to the top surface of the column 55, a plurality of nozzles 531 are vertically fixedly connected to the oil injection pipe 53, the plurality of nozzles 531 respectively correspond to the positions of the plurality of through holes 521, the nozzles 531 can pass through the through holes 521 to the top surface of the casing 52, an oil delivery component 54 is arranged on the top surface of the base 1, and the oil delivery component 54 can deliver lubricating oil to the oil injection pipe 53.

[0032] Before assembling the pulley and the automobile parts, the pulley is placed on the top surface of the casing 52, and then the pulley is pressed down to make the casing 52 compress the spring 57 and slide down. When the bottom surface of the casing 52 contacts the top surface of the support plate 51, the nozzle 531 on the oil injection pipe 53 passes through the through hole 521 and extends to the top surface of the casing 52. At this time, the oil delivery component 54 delivers lubricating oil to the oil injection pipe 53 and sprays the lubricating oil on the pulley through the nozzle 531, so that the pulley is automatically oiled. After the pulley is removed, the pressure applied to the casing 52 disappears, and the casing 52 slides up and resets under the elastic force of the spring 57. The setting of the rubber sheet 522 can prevent dust and impurities from entering the interior of the casing 52, and the setting of the cross 523 can enable the nozzle 531 to pass through the rubber sheet 522, so as to ensure that the pulley oiling work can be carried out normally.

[0033] like Figure 3 and Figure 4As shown, the oil delivery assembly 54 includes a material box 541, a pump body 542, an oil inlet pipe 543 and an oil outlet pipe 544. The material box 541 is fixedly connected to the top surface of the base 1. Lubricating oil is contained in the material box 541. The pump body 542 is installed on the top surface of the base 1. One end of the oil inlet pipe 543 is fixedly connected to the input end of the pump body 542, and the other end is fixedly connected to the side wall of the material box 541 to connect the material box 541 and the pump body 542. One end of the oil outlet pipe 544 is fixedly connected to the output end of the pump body 542, and the other end passes through the side wall of the casing 52 and is fixedly connected to the side wall of the oil injection pipe 53 to connect the pump body 542 and the oil injection pipe 53.

[0034] Starting the pump body 542 can transport the lubricating oil in the material box 541 to the oil injection pipe 53 through the oil inlet pipe 543 and the oil outlet pipe 544, so that the nozzle 531 sprays the lubricating oil on the pulley, thereby realizing automatic oiling of the pulley.

[0035] like Figure 1 and Figure 3 As shown, the top surface of the base 1 is provided with a mounting block 2, a limiting frame 3 and a riveting device 4. The limiting frame 3 is located on the top surface of the base 1 on one side of the mounting block 2. The limiting frame 3 is provided with a pair of notches 31 that can cooperate with the ends of automobile parts. The riveting device 4 is arranged on the top surface of the base 1 on one side of the mounting block 2. The output end of the riveting device 4 is located at the top of the mounting block 2 and is coaxial with the mounting block 2. The riveting device 4 is a prior art and will not be described in detail here. A detection control mechanism 6 is also provided on the top surface of the base 1. The detection control mechanism 6 can detect whether the pump body 542 is working and control the opening and closing of the riveting device 4.

[0036] When the detection control mechanism 6 detects that the pump body 542 is started and the pulley is oiled, the riveting device 4 can work normally. During assembly, the oiled pulley is first assembled with the rivet, and then the pulley with the rivet is assembled at the riveting position at one end of the automobile part, and the assembled automobile part is placed on the mounting block 2 and the limiting frame 3, so that the riveted end of the automobile part is placed on the mounting block 2, and the other end is correspondingly clamped in the notch 31 of the limiting frame 3, and then the limiting plate is installed on the top of the riveting position of the automobile part, and finally the parts on the mounting block 2 are riveted by the riveting device 4 to realize the pulley assembly. If the detection control mechanism 6 does not detect that the pump body 542 is started to oil the pulley, the riveting device 4 does not work, thereby reducing the occurrence of the pulley being assembled without oiling.

[0037] like Figure 3 and Figure 4As shown, the detection control mechanism 6 includes a pressure sensor 61 and a first controller 62. The pressure sensor 61 is arranged on the top surface of the support plate 51 to detect the pressure on the support plate 51. The first controller 62 is arranged on the top surface of the base 1. The output end of the pressure sensor 61 is electrically connected to the input end of the first controller 62. The output end of the first controller 62 is electrically connected to the pump body 542 and the riveting device 4. The first controller 62 controls the opening and closing of the pump body 542 and the riveting device 4.

[0038] The pressure sensor 61 detects the pressure on the top surface of the support plate 51 and transmits the detection data to the first controller 62. When the pulley is placed on the top surface of the casing 52 and the casing 52 is pressed down, the pressure sensor 61 detects the pressure change, and the first controller 62 first controls the pump body 542 to start oiling the pulley and turns on the riveting device 4 so that the riveting device 4 can work normally. When the pulley is not placed on the top surface of the casing 52 and the casing 52 is not pressed down, the second controller 83 will not control the pump body 542 to start oiling, and the riveting device 4 will not work.

[0039] like Figure 3 and Figure 5 As shown, a fixed block 7 located at one side of the mounting block 2 is fixedly connected to the top surface of the base 1, and a slide groove 71 is provided on the top surface of the fixed block 7. A slider 8 is slidably connected to the inner side wall of the slide groove 71, and a groove 85 is provided on the bottom surface of the slider 8. A guide rail 72 is fixedly connected to the bottom wall of the slide groove 71. The guide rail 72 is arranged along the length direction of the slide groove 71 and passes through the groove 85 on the bottom surface of the slider 8. The guide rail 72 slides with the inner wall of the groove 85. A connecting plate 81 extending to the outside of the fixed block 7 is fixedly connected to the side of the slider 8 close to the mounting block 2, and a height sensor 9 is provided at the end of the connecting plate 81 away from the slider 8. A cylinder 82 arranged along the length direction of the slide groove 71 is provided on the inner wall of one end of the slide groove 71, and the output end of the cylinder 82 is fixedly connected to the side wall of the slider 8. A second controller 83 is provided on the top surface of the slider 8, and the output end of the height sensor 9 is electrically connected to the input end of the second controller 83. A warning light 84 is fixedly connected to the top surface of the connecting plate 81, and the output end of the second controller 83 is electrically connected to the warning light 84 to control the turning on and off of the warning light 84.

[0040] After completing the riveting work between the pulley and the automobile parts on the mounting block 2, the cylinder 82 will push the slider 8 to drive the connecting plate 81 to move, prompting the height sensor 9 to move to the top of the mounting block 2, detect the height of the rivet after riveting, and transmit the detection data to the second controller 83. When the height data received by the second controller 83 does not meet the requirements, the second controller 83 will control the warning light 84 to light up, reminding the staff that the riveting work does not meet the requirements, so that the staff can more intuitively understand whether the assembled parts are qualified. After detecting the height, the cylinder 82 will drive the slider 8 to move back and reset so that the height sensor 9 can be detected again.

[0041] Working principle: When the pulley is installed on the automobile part by riveting, first take the pulley to be installed and place it on the casing 52 and press the pulley down, so that the casing 52 compresses the spring 57 and moves down along the outer wall of the column 55 until it contacts the support plate 51. At this time, the nozzle 531 on the oil injection pipe 53 passes through the through hole 521 and extends to the top surface of the casing 52. The pressure sensor 61 transmits the detected pressure change data to the first controller 62. The first controller 62 controls the pump body 542 to work. The pump body 542 transports the lubricating oil in the material box 541 to the oil injection pipe 53 and sprays it on the pulley through the nozzle 531 to achieve pulley oiling. Then the pulley is manually removed and the oiled pulley is assembled with the rivet. Then assemble the pulley with rivets at the riveting position at one end of the automobile part, and place the assembled automobile part on the mounting block 2 and the limit frame 3, and then install the limit plate on the top of the riveting position of the automobile part, and then use the riveting device 4 to rivet the parts on the mounting block 2 as a whole to realize the pulley assembly; if the staff does not place the pulley on the top surface of the casing 52 and press the casing 52 down to contact the support plate 51, after the pressure sensor 61 transmits pressure data to the second controller 83, the second controller 83 will not control the pump body 542 to start the pulley oiling work, and the riveting device 4 will not work, thereby reducing the occurrence of the pulley being assembled without oiling and reducing the defective rate.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
