Description

Technical Field

[0001] This invention relates to the field of riveting equipment technology, specifically a reverse riveting device for a production line. Background Technology

[0002] Riveting is the process of connecting two or more workpieces using rivets. For example, the holes for shoelaces on sneakers are made by hollow rivets. Riveting uses axial force to thicken the rivet shank inside the rivet hole and form a rivet head, thus connecting multiple workpieces. Riveting is widely used in the machinery and automotive industries. When riveting car locks, the car lock blanks need to be riveted from the bottom of the production line. Setting up anchors directly below the production line will affect the operation of the production line. Currently, the common practice is to manually flip the car locks, then rivet them from the top of the car locks and then put them back on the production line, resulting in low riveting efficiency of the car lock parts.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-7 The technical solution provided by the present invention specifically includes the following embodiments: A reverse riveting device for an assembly line, characterized in that: it includes a frame 1, a workbench 101 fixedly connected to the top of the frame 1, a riveting pressure table 102 fixedly connected to the top of the workbench 101, a riveting mechanism 5 fixedly installed at the bottom of the workbench 101, a lifting component 3 provided at the front of the workbench 101, a fixed seat 103 fixedly installed on the top of the workbench 101, the fixed seat 103 being located at the front end of the riveting pressure table 102, two symmetrically distributed connecting side panels 104 fixedly installed on the top of the fixed seat 103, the front ends of the two connecting side panels 104 being connected to an end plate 105, rectangular slots 106 penetrating through the lower part of the opposite side of the two connecting side panels 104, L-shaped baffles 107 rotatably installed inside the two rectangular slots 106, and the bottom of the end plate 105 being fixedly installed with... There is an assembly base 1012. A lifting component 3 is fixedly installed on the lower back of the assembly base 1012. The lifting component 3 includes a lifting seat 301 fixedly installed on the lower back of the assembly base 1012. A lifting cylinder 302 is fixedly installed at the bottom of the lifting seat 301. A lifting bracket 303 is fixedly installed at the top of the lifting cylinder 302. A tooling plate 304 is connected to the top of the lifting bracket 303. A connecting plate 305 is fixedly installed on the left and right sides of the lifting bracket 303. A secondary cylinder 306 is fixedly installed on the lower part of the side of the two connecting plates 305 that are far apart. A baffle 307 is fixedly installed at the top of the output rod of the two secondary cylinders 306. A plurality of columns 2 are fixedly provided at the front end of the frame 1. A flow conveyor chain 4 is connected to the top of the plurality of columns 2. The flow conveyor chain 4 is located on the top of the lifting bracket 303. Two fixed ears 108 are fixedly installed on the opposite sides of the two L-shaped baffles 107. A first bolt 109 is fixedly installed on the opposite sides of the two fixed ears 108. A second bolt 1010 is fixedly installed on the upper part of the opposite side of the two connecting side panels 104 and the upper part of the left and right sides of the end plate 105. There are four second bolts 1010 in total. The second bolts 1010 are located on top of the first bolts 109 respectively. A tension spring 1011 is connected between the first bolts 109 and the second bolts 1010 at the corresponding positions. A push cylinder 6 is fixedly installed on the top of the assembly base 1012. A telescopic hole 1005 is opened through the front of the end plate 105. The position of the push cylinder 6 corresponds to the position of the telescopic hole 1005. A reverse push cylinder 7 is fixedly installed at the rear end of the top of the worktable 101. The reverse push cylinder 7 and the push cylinder 6 are symmetrically distributed front and back. Specifically, when the workpiece, along with the tooling plate 304 carrying the workpiece, is transported by the conveyor chain 4 to a position directly above the lifting bracket 303, the output rod of the lifting cylinder 302 pushes the lifting bracket 303 upward. This upward movement of the lifting bracket 303 further pushes the tooling plate 304, along with the workpiece on its top, upward until the left and right sides of the tooling plate 304 contact the bottom of the two L-shaped baffles 107. Under the upward thrust of the tooling plate 304, the two L-shaped baffles 107... The two L-shaped baffles 107 rotate synchronously outwards from the junction with the two rectangular slots 106. This rotation causes the fixing ears 108 and the first bolt 109 to rotate together. The rotation of the first bolt 109 with the fixing ears 108 stretches the tension spring 1011, causing the second bolt 1010 to rebound. When the tooling plate 304 rises above the lowest point of the L-shaped baffles 107, the output rod of the lifting cylinder 302 drives the lifting bracket 303 to move downwards and reset. Spring 1011 elastically contracts, pulling the first bolt 109, fixing lug 108, and L-shaped baffle 107 to rotate and reset along the junction of L-shaped baffle 107 and rectangular slot 106. At this time, the tooling plate 304 has been lifted and is supported by the top surface of the bent part of the two reset L-shaped baffles 107. Then, the output rod of cylinder 6 pushes the tooling plate 304 and the workpiece from between the two L-shaped baffles 107 to the top of the riveting mechanism 5. Then, the output end of the riveting mechanism 5... The bottom of the tooling plate 304 is riveted to the workpiece to be riveted. After the riveting is completed, the output rod of the reverse thrust cylinder 7 pushes the tooling plate 304 and the riveted workpiece between the two L-shaped baffles 107, so that the tooling plate 304 and the riveted workpiece are supported again by the top surface of the bend of the two L-shaped baffles 107. Then the output rod of the lifting cylinder 302 drives the lifting bracket 303 to move upward again, lifting the tooling plate 304 and the riveted workpiece upward from between the two L-shaped baffles 107. At the same time, the lifting bracket 303 moves upward, causing the two connecting plates 305 and the two auxiliary cylinders 306 to move upward together. The output rods of the two auxiliary cylinders 306 drive the two baffles 307 to move upward. The upward movement of the two baffles 307 pushes against their horizontal ends, causing the two L-shaped baffles 107 to rotate outward again. The tension spring 1011 stretches and stores force again. At this time, the output rod of the lifting cylinder 302 retracts downward, causing the lifting bracket 303 to move downward. Due to the movement of the two L-shaped baffles 107... When rotated outward, the tooling plate 304 is no longer supported by the L-shaped baffle 107, causing the tooling plate 304, along with the riveted workpiece, to move downward with the lifting bracket 303 until it falls onto the conveyor chain 4. After the tooling plate 304 falls onto the conveyor chain 4, the output rods of the two auxiliary cylinders 306 retract downward, driving the two baffles 307 to move downward and reset, releasing the top force on the horizontal ends of the two L-shaped baffles 107. The tension spring 1011 is elastically released, thereby driving the two L-shaped baffles 107 to reverse and reset.

[0019] Furthermore, the two baffles 307 are located at the bottom of the two L-shaped baffles 107 respectively, and the positions of the two baffles 307 correspond one-to-one with the positions of the two L-shaped baffles 107. It should be noted that by setting the two baffles 307 at the bottom of the two L-shaped baffles 107, the two baffles 307 move upward and push against the horizontal ends of the two baffles 307, causing the two L-shaped baffles 107 to rotate outward again. As the two L-shaped baffles 107 rotate outward, the tooling plate 304 is no longer supported by the L-shaped baffles 107, causing the tooling plate 304, along with the riveted workpiece, to fall on the top of the lifting bracket 303 and be moved downward by the lifting bracket 303 to the upper end of the conveyor chain 4.

[0020] Furthermore, two guide rods 308 are fixedly installed on the bottom of the lifting bracket 303, which are distributed on the left and right. Both guide rods 308 movably pass through the top and bottom of the lifting seat 301, and the outer walls of the two guide rods 308 are slidably connected to the inner wall of the through hole between the lifting seat 301. It should be noted that by setting two guide rods 308 to slide between them and the lifting seat 301, a precise guiding effect is provided for the upward and downward movement of the lifting bracket 303, so that the trajectory of the upward and downward movement of the lifting bracket 303 is well consistent and accurate, ensuring the accuracy of the upward and downward movement of the lifting bracket 303.

[0021] Furthermore, the distance between the two L-shaped baffles 107 matches the left and right width of the tooling plate 304; It should be noted that the distance between the two L-shaped baffles 107 matches the left and right widths of the two tooling plates 304. This is so that when the two tooling plates 304 move upward, the left and right sides of the tooling plates 304 will press against the bottom of the horizontal ends of the two L-shaped baffles 107, thereby causing the two L-shaped baffles 107 to rotate outward, thus pushing the tooling plates 304 between the two L-shaped baffles 107.

[0022] Furthermore, the riveting mechanism 5 is located at the bottom of the fixed base 103, and the top of the fixed base 103 is provided with a clearance hole 1003 extending downward. The output end of the riveting mechanism 5 passes through the clearance hole 1003 and extends to the space between the left and right connecting side panels 104. It should be noted that by setting the clearance hole 1003, the output end of the riveting mechanism 5 can perform riveting processing on the workpiece pushed to the top of the clearance hole 1003, avoiding interference from the fixed seat 103 on the output end of the riveting mechanism 5, and ensuring the reasonable operation of the device.

[0023] Furthermore, guide blocks 1013 are fixedly installed on the lower part of the side of the two connecting side panels 104 that are close to each other. The top height of the two guide blocks 1013 is flush with the top surface height of the bend of the two L-shaped baffles 107. Limit blocks 10131 are fixedly installed at the top rear end of the two guide blocks 1013. It should be noted that after the lifting bracket 303 pushes the tooling plate 304 and the workpiece between the two L-shaped baffles 107, the push cylinder 6 pushes the tooling plate 304 backward to the top of the two guide blocks 1013, so that the tooling plate 304 slides along the top surface of the two guide blocks 1013, thereby providing sliding support and sliding guidance for the tooling plate 304. At the same time, the two limit blocks 10131 can limit the backward sliding position of the tooling plate 304 to prevent the tooling plate 304 from sliding excessively. After riveting, the output rod of the reverse push cylinder 7 pushes the tooling plate 304 together with the workpiece to slide forward along the top of the two guide blocks 1013, so that the tooling plate 304 and the workpiece can accurately enter between the two L-shaped baffles 107, ensuring the precise operation of the device.

[0024] Furthermore, two positioning posts 3003 are fixedly installed on the top of the lifting bracket 303, and two positioning holes 3004 are opened on the bottom of the tooling plate 304, with the positions of the two positioning holes 3004 corresponding one-to-one with the positions of the two positioning posts 3003, and the specifications of the two positioning holes 3004 being compatible with the specifications of the two positioning posts 3003. It should be noted that when the lifting bracket 303 moves upward to lift the tooling plate 304, the top surface of the lifting bracket 303 contacts the bottom surface of the tooling plate 304. At this time, the two positioning pins 3003 will be inserted into the interior of the two positioning holes 3004, thereby limiting the tooling plate 304 to the top of the lifting bracket 303. This can prevent the tooling plate 304 from shifting during the upward movement, so that the tooling plate 304 can accurately enter between the two L-shaped baffles 107.

[0025] In this reverse riveting assembly line device, during operation, the workpiece, along with the tooling plate 304 carrying the workpiece, is conveyed by the conveyor chain 4 to a position directly above the lifting bracket 303. The output rod of the lifting cylinder 302 then pushes the lifting bracket 303 upwards. This upward movement of the lifting bracket 303 further pushes the tooling plate 304, along with the workpiece on its top, upwards until the left and right sides of the tooling plate 304 contact the bottom of the two L-shaped baffles 107. Under the upward thrust of the tooling plate 304, the two L-shaped baffles 107 are moved along the transition lines with the two rectangular slots 106. The two L-shaped baffles 107 rotate synchronously outwards, causing the fixing ears 108 and the first bolt 109 to rotate together. The rotation of the first bolt 109 with the fixing ears 108 stretches the tension spring 1011, causing the second bolt 1010 to generate a rebound force. When the tooling plate 304 rises to a height higher than the lowest point of the L-shaped baffles 107, the output rod of the lifting cylinder 302 drives the lifting bracket 303 to move downwards and reset. The two tension springs 1011 elastically contract, pulling the first bolt 109, the fixing ears 108, and the L-shaped baffles 107 along the L-shaped baffles 107. The fixture plate 304 is rotated and reset in the opposite direction to the transition point of the rectangular slot 106. At this time, the fixture plate 304 has been lifted and is supported by the top surface of the bent part of the two reset L-shaped baffles 107. Then, the output rod of the cylinder 6 pushes the fixture plate 304 and the workpiece from between the two L-shaped baffles 107 to the top of the two guide blocks 1013, and slides backward along the top of the two guide blocks 1013 until the rear end of the fixture plate 304 abuts against the front of the two limit blocks 10131. At this time, the output rod of the cylinder 6 retracts, and the fixture plate 304 and the workpiece are just located in the riveting mechanism 5. At the top, the output end of the riveting mechanism 5 rivets the workpiece to be riveted from the bottom of the tooling plate 304. After the riveting is completed, the output rod of the reverse thrust cylinder 7 pushes the tooling plate 304 and the riveted workpiece to slide between the two L-shaped baffles 107 along the top surface of the two guide blocks 1013, so that the tooling plate 304 and the riveted workpiece are supported again by the top surface of the bend of the two L-shaped baffles 107. Then the output rod of the lifting cylinder 302 drives the lifting bracket 303 to move upward again, lifting the tooling plate 304 and the riveted workpiece upward from between the two L-shaped baffles 107. At the same time, the lifting bracket 303 moves upward, causing the two connecting plates 305 and the two auxiliary cylinders 306 to move upward together. The output rods of the two auxiliary cylinders 306 drive the two baffles 307 to move upward. The upward movement of the two baffles 307 pushes against their horizontal ends, causing the two L-shaped baffles 107 to rotate outward again. The tension spring 1011 stretches and stores force again. At this time, the output rod of the lifting cylinder 302 retracts downward, causing the lifting bracket 303 to move downward. Due to the movement of the two L-shaped baffles 107... When rotated outward, the tooling plate 304 is no longer supported by the L-shaped baffle 107, causing the tooling plate 304, along with the riveted workpiece, to move downward with the lifting bracket 303 until it falls onto the conveyor chain 4. After the tooling plate 304 falls onto the conveyor chain 4, the output rods of the two auxiliary cylinders 306 retract downward, driving the two baffles 307 to move downward and reset, releasing the top force on the horizontal ends of the two L-shaped baffles 107. The tension spring 1011 is elastically released, thereby driving the two L-shaped baffles 107 to reverse and reset.
