Description

Technical Field

[0001] This utility model relates to the field of hinge production equipment, specifically to a riveting detection mechanism. Background Technology

[0002] A riveting module includes a transfer gripper, a rivet detector, a circular conveyor line, a fixing block, a rejection pusher, multiple riveting machines, and several riveting carriers. The riveting carriers are slidably mounted on the circular conveyor line along its movement trajectory. The transfer gripper is located at the loading end of the circular conveyor line and is used to transfer the workpiece to the riveting carrier. The fixing block is movably mounted above the circular conveyor line and on the same side as the riveting machines, used to descend and fix the workpiece to the riveting carrier. The rivet detector and multiple riveting machines are sequentially arranged on one side of the circular conveyor line. The rivet detector is used to detect whether there is a rivet in the connecting hole of the workpiece. The rejection pusher is located on the other side of the circular conveyor line and is used to reject workpieces without rivets in the connecting hole. Because the rivet detector of this riveting module is located before the riveting machine's operation, it only detects whether there is a rivet in the connecting hole of the workpiece, but cannot detect whether the rivet is properly riveted. If the rivet is not properly riveted, defective products are easily produced, affecting product quality. In addition, the number of fixed pressure blocks must match the number of riveting machines, and the two must be set one-to-one. If the fixed pressure blocks are to be driven to descend, multiple lifting drive devices are required, resulting in a large number of parts, which is not conducive to reducing production costs. Utility Model Content

[0003] The purpose of this invention is to provide a riveting inspection mechanism that can detect whether the riveting is in place after the riveting operation and can reduce production costs.

[0004] To achieve the above objectives, this utility model provides a riveting inspection mechanism, comprising a worktable, an inspection component, a clamping component, a transfer component, several tooling components, and several riveting machines. The tooling components are arranged along a first direction on the worktable. The riveting machines and the inspection component are respectively located on one side of their respective tooling components. In the first direction, the inspection component is located at the rear end of the riveting machine. The clamping component includes a first driving device, a crossbar, and several pressing blocks. The crossbar extends along the first direction, and the pressing blocks are arranged on the crossbar, with the pressing blocks corresponding vertically to the tooling components. The first driving device drives the crossbar to rotate around its own axis, thereby causing the pressing blocks to flip up and down. The transfer component is located on one side of the tooling components and includes several clamps that can move back and forth between adjacent tooling components.

[0005] As can be seen from the above scheme, by setting the detection component at the rear end of the riveting machine, it is convenient to check whether the rivets on the workpiece are riveted in place after the riveting operation, which helps to ensure the quality of the workpiece; by setting the first driving device to drive the crossbar to rotate, thereby driving all the lower pressure blocks to flip up and down together, the workpieces on multiple tooling components can be pressed or released simultaneously. Compared with the existing technology, it has the advantage of saving the number of driving devices, which helps to reduce production costs; by setting the transfer component, the workpiece can be transferred from the previous tooling component to the next tooling component, which facilitates the riveting operation of rivets at different positions on the workpiece.

[0006] A further embodiment is that the detection assembly includes a detection base, a detection movable seat, a detector, a telescopic rod, and a detection translation drive device. The detection movable seat is slidably mounted on the detection base, and the detection translation drive device can drive the detection movable seat to move towards the tooling assembly. The detector and the telescopic rod are arranged on the detection movable seat along the moving direction of the detection movable seat, and the stop end of the telescopic rod protrudes from the first end of the detection movable seat, and the test end of the telescopic rod protrudes from the second end of the detection movable seat and can move closer to or away from the detection end of the detector.

[0007] As can be seen from the above scheme, with the above settings, when the detection movable seat drives the telescopic rod to move towards the workpiece on the tooling assembly, the stop end of the telescopic rod abuts against the rivet on the workpiece and stops moving. At this time, the detection movable seat continues to move, so that the test end of the telescopic rod approaches the detection end of the detector. If the test end of the telescopic rod enters the detection range of the detector, it means that the rivet is not properly riveted.

[0008] A further embodiment includes a clamping fixing seat, a rack, a gear, and at least two support seats. The clamping fixing seat is disposed between two adjacent support seats, and the two ends of the crossbar are respectively disposed on the two support seats. The gear is sleeved on the crossbar, and the rack extends vertically and is disposed on the clamping fixing seat. The gear and the rack are meshed and connected. The first driving device can drive the rack to move up and down, thereby driving the crossbar to rotate through the gear.

[0009] As can be seen from the above scheme, with the above configuration, the first drive device is connected to the rack and gear to drive the crossbar to rotate, which facilitates the simultaneous up-and-down flipping of multiple pressure blocks.

[0010] A further proposed solution is to use twice the number of pressure blocks as tooling components, with each tooling component having two pressure blocks, and the two pressure blocks being set to correspond to the two ends of the tooling component respectively.

[0011] A further embodiment includes a transfer fixing frame, a transfer translation frame, a transfer lifting frame, a transfer translation drive device, and a first transfer lifting drive device. The transfer translation frame and the transfer lifting frame are both movably mounted on the transfer fixing frame. The transfer translation drive device can drive the transfer translation frame to move back and forth along a first direction, and the first transfer lifting drive device can drive the transfer lifting frame to move up and down. A plurality of clamps are arranged along the first direction on the transfer lifting frame and / or the transfer translation frame.

[0012] A further embodiment is that the fixture includes a first fixture and several second fixtures. The first fixture is mounted on a transfer and translation frame, and the several second fixtures are arranged on a transfer and lifting frame. The transfer and translation frame is also equipped with a second transfer and lifting drive device, which can drive the first fixture to move up and down.

[0013] As can be seen from the above scheme, by setting the first fixture, the workpiece is picked up from the previous workstation and transferred to the first tooling assembly, thus realizing the automatic feeding of the workpiece; by setting the second fixture, the workpiece is picked up from the previous tooling assembly and transferred to the next tooling assembly, which facilitates the riveting operation for rivets in different positions.

[0014] A further solution is to also install an angle adjustment component on the worktable, with the angle adjustment component located at the front end of all riveting machines in the first direction.

[0015] As can be seen from the above scheme, by setting the workpiece into the tooling assembly, the angle adjustment component can be used to adjust the angle between the workpiece's hinge arm and the hinge cup before the workpiece is placed into the tooling assembly, ensuring that the workpiece can be placed into the tooling assembly at a preset angle, which helps to ensure the accuracy of the subsequent riveting position.

[0016] A further option is that the angle adjustment component includes two pushers that are positioned vertically and vertically, and the two pushers can be relatively close to each other or relatively far apart.

[0017] A further option is to also set up several side-top components on the workbench, with each side-top component corresponding to a riveting machine, and the side-top components and riveting machines respectively set on both sides of the tooling assembly.

[0018] As can be seen from the above scheme, by setting it up as described above, before riveting, the rivet to be riveted is pressed tightly from one side of the workpiece by the side top component, ensuring that the riveting operation is carried out smoothly.

[0019] A further embodiment includes a side-top fixed base, a side-top adjusting block, a side-top mating base, a wedge, a side-top movable block, a side-top rod, a side-top elastic element, and a side-top driving device. The side-top adjusting block is adjustable up and down on the side-top fixed base. The side-top mating base is fixedly connected to the side-top adjusting block. The wedge is movably connected between the side-top mating base and the side-top adjusting block. The side-top movable block is movably disposed within the side-top mating base, with its first end abutting against the wedge. The second end of the side-top movable block is provided with a side-top rod. The side-top elastic element is elastically connected between the side-top movable block and the side-top mating base. The side-top driving device drives the wedge to move up and down, thereby driving the side-top movable block and the side-top rod to move towards the tooling assembly.

[0020] As can be seen from the above scheme, by pressing one end of the rivet to be riveted with the side top rod, it is convenient for the riveting rod of the riveting machine to perform riveting operation on the other end of the rivet; by setting the side top adjustment block, it is convenient to make appropriate adjustments according to the different height positions of the rivet, which is beneficial to the compatibility of rivets of different heights.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0029] See Figure 1 and Figure 3The riveting inspection mechanism provided in this embodiment includes a worktable 1, an inspection component 2, a clamping component 3, a transfer component 4, an angle adjustment component 5, several side-mounted components 6, several tooling components 7, and several riveting machines 8. This embodiment takes four tooling components 7, three riveting machines 8, and three side-mounted components 6 as an example. The workpiece 9 is placed on the tooling component 7. In this embodiment, the workpiece 9 is preferably a buffer hinge, which includes a hinge arm 91 and a hinge cup 92 that can rotate relative to each other.

[0030] Four tooling components 7 are arranged along the first direction X on the middle of the workbench 1. Three riveting machines 8 and a detection component 2 are arranged along the first direction X on the workbench 1, and the three riveting machines 8 and the detection component 2 are all located on the same side of the four tooling components 7. Three side-top components 6 are arranged in a one-to-one correspondence with the three riveting machines 8, and the side-top components 6 and the riveting machines 8 are respectively located on both sides of the corresponding tooling component 7 in the second direction Y, which is perpendicular to the first direction X.

[0031] The clamping assembly 3 is positioned above the four tooling assemblies 7 and is used to clamp the workpiece 9 from above.

[0032] The transfer component 4 is located on one side of the tooling component 7. The transfer component 4 includes several clamps that can move back and forth between two adjacent tooling components 7 to realize the position transfer of the workpiece 9.

[0033] In the first direction X, the angle adjustment component 5 is located at the front end of all riveting machines 8, which facilitates the pre-adjustment of the included angle between the hinge arm 91 and the hinge cup 92 of the workpiece 9, ensuring that the workpiece 9 can accurately cooperate with the tooling component 7, and also helps to improve the accuracy of the riveting position.

[0034] In the first direction X, the detection component 2 is located at the rear end of all riveting machines 8 and is used to detect the workpiece 9 after the riveting operation, which is beneficial to detect defective products where the rivets are not properly riveted.

[0035] In this embodiment, along the first direction X, the end that the workpiece 9 reaches first is the front end, and the workpiece 9 moves backward along the first direction X, that is... Figure 1 The left side of the image represents the front end, and the right side represents the back end.

[0036] exist Figure 2 In the process, the transfer assembly 4 also includes a transfer fixing frame 41, a transfer translation frame 42, a transfer lifting frame 43, a transfer translation drive device 44, and a first transfer lifting drive device 45.

[0037] A transfer fixing frame 41 is disposed on one side of all tooling components 7. A transfer translation frame 42 extends along a first direction X and is disposed on the transfer fixing frame 41. A transfer translation drive device 44 can drive the transfer translation frame 42 to move back and forth along the first direction X. A transfer lifting frame 43 is disposed on the transfer translation frame 42. A first transfer lifting drive device 45 can drive the transfer lifting frame 43 to move up and down back and forth. The transfer translation drive device 44 and the first transfer lifting drive device 45 can be pneumatic cylinders or hydraulic cylinders.

[0038] Several clamps are arranged along the first direction X on the transfer lifting frame 43 and / or transfer translation frame 42. Specifically:

[0039] The fixture includes a first fixture 46 and four second fixtures 47, both of which are pneumatic or hydraulic fixtures. The first fixture 46 is located at the front end of the transfer frame 42, and all the second fixtures 47 are arranged on the transfer lifting frame 43, so that the first fixture 46 and all the second fixtures 47 can move back and forth synchronously along the first direction X with the transfer frame 42, and the four second fixtures 47 can move up and down synchronously with the transfer lifting frame 43.

[0040] The transfer frame 42 is also equipped with a second transfer lifting drive device 48, which can independently drive the first clamp 46 to move up and down. The second transfer lifting drive device 48 can be a pneumatic cylinder or a hydraulic cylinder.

[0041] The front end of the transfer frame 42 is provided with a turntable (not shown in the figure) and an angle adjustment assembly 5. The turntable is provided with multiple fixing assemblies 10 for fixing the workpiece 9. The fixing assemblies 10 clamp and fix the workpiece 9 from one end of the hinge cup 92, and the hinge arm 91 of the workpiece 9 protrudes beyond the fixing assembly 10. The first clamp 46 can grab the workpiece 9 on the fixing assembly 10 and transfer it to the angle adjustment assembly 5.

[0042] The angle adjustment component 5 includes two vertically aligned pushers that can be positioned closer or further apart. Specifically:

[0043] The upper pusher is a pressure rod 51, which is located on one side of the first clamp 46. The pressure rod 51 can move up and down and horizontally synchronously with the first clamp 46. The lower part of the pressure rod 51 extends downward beyond the clamping opening of the first clamp 46, so that before clamping the workpiece 9, the pressure rod 51 can push the hinge arm 91 of the workpiece 9 downward to rotate downward.

[0044] The lower pusher includes a support 52 and a pusher drive 53. The support 52 is vertically aligned with the pressure rod 51. The pusher drive 53 can drive the support 52 to move towards the pressure rod 51. The pusher drive 53 can be a pneumatic cylinder or a hydraulic cylinder. The hinge arm 91 of the workpiece 9 can enter between the pressure rod 51 and the support 52. The lifting and lowering of the support 52 ensures that the hinge arm 91 stops rotating after rotating to a certain position, ensuring that the hinge cup 92 and the hinge arm 91 are at a suitable angle that is basically horizontal.

[0045] Combination Figure 3 and Figure 4 The clamping assembly 3 includes a first driving device 31, a clamping fixing seat 32, a crossbar 33, three support seats 34, and eight pressing blocks 35.

[0046] Three support seats 34 are arranged along the first direction X, and a clamping fixing seat 32 is disposed between two adjacent support seats 34. A crossbar 33 extends along the first direction X, with its two ends respectively disposed on the two outermost support seats 34, and its middle part disposed on another support seat 34. Eight pressing blocks 35 are arranged between the two ends of the crossbar 33, and every two pressing blocks 35 are vertically corresponding to one tooling assembly 7. A gear 36 is also sleeved between the two ends of the crossbar 33, and a rack 37 is disposed on the clamping fixing seat 32. The rack 37 extends along the vertical direction Z, and the gear 36 meshes with the rack 37.

[0047] The first driving device 31 can be a pneumatic cylinder or a hydraulic cylinder. The first driving device 31 drives the rack 37 to move up and down, thereby driving the gear 36 to rotate in both directions, which in turn drives the crossbar 33 to rotate in both directions around its own axis, thereby driving the lower pressure block 35 to flip up and down.

[0048] In this embodiment, the number of pressing blocks 35 is twice the number of tooling components 7. Each tooling component 7 corresponds to two pressing blocks 35, and the two pressing blocks 35 are respectively set at both ends of the tooling component 7 to facilitate pressing the workpiece 9 from both ends. A gasket 351 is provided at the free end of the pressing block 35. The gasket 351 can directly contact the workpiece 9 to prevent scratching the surface of the workpiece 9. The gasket 351 can be a rubber gasket, nylon gasket, silicone gasket, etc.

[0049] See Figure 5 The riveting machine 8 can be a pneumatic riveting machine or a hydraulic riveting machine, etc. The riveting rod of the riveting machine 8 is aligned with one end of the rivet on the workpiece 9 on the tooling assembly 7.

[0050] The side top assembly 6 includes a side top fixing seat 61, a side top adjusting block 62, a side top mating seat 63, a wedge block 64, a side top movable block 65, a side top rod 66, a side top elastic element 67, and a side top driving device 68.

[0051] The side top adjusting block 62 is mounted on the side top fixing base 61 by screws, and the height of the side top adjusting block 62 on the side top fixing base 61 is adjustable. The side top adjusting block 62 has a first mounting hole; the side top fixing base 61 has a second mounting hole, which is an elongated hole extending in the vertical direction Z, and the screw passes through the second mounting hole and connects to the first mounting hole.

[0052] The side-top mating seat 63 is fixedly connected to the side-top adjusting block 62, and a vertically extending channel is formed between the side-top mating seat 63 and the side-top adjusting block 62; the wedge block 64 is disposed in the channel between the side-top mating seat 63 and the side-top adjusting block 62, and the wedge block 64 can move up and down. The wedge block 64 is provided with an inclined surface.

[0053] The side top movable block 65 is arranged in the side top mating seat 63 along the second direction Y, and the first end of the side top movable block 65 can abut against the inclined surface of the wedge block 64. The second end of the side top movable block 65 is provided with a side top rod 66, which is correspondingly arranged with the rivet of the workpiece 9.

[0054] A side-top elastic element 67 is elastically connected between the side-top movable block 65 and the side-top mating seat 63. Specifically, a mounting rod 651 is provided on the side wall of the side-top movable block 65, and a mating part 631 is provided on one side of the side-top mating seat 63. The two ends of the side-top elastic element 67 are respectively connected to the mounting rod 651 and the mating part 631, so that the side-top movable block 65 has the potential energy to move towards the wedge block 64. The side-top elastic element 67 is preferably a spring.

[0055] The side-top drive device 68 can be a pneumatic cylinder or a hydraulic cylinder. The side-top drive device 68 drives the wedge block 64 to move up and down, thereby driving the side-top movable block 65 and the side-top rod 66 to move towards the tooling assembly 7, so that the side-top rod 66 can abut against the other end of the rivet of the workpiece 9.

[0056] Combination Figure 6 and Figure 7 The detection component 2 includes a detection base 21, a detection movable seat 22, a detection translation drive device 23, four detectors 24, and four telescopic rods 25.

[0057] The detection movable seat 22 is slidably mounted on the detection base 21 along the second direction Y; the detection translation drive device 23 can be a pneumatic cylinder or a hydraulic cylinder, and the detection translation drive device 23 can drive the detection movable seat 22 to move towards the tooling assembly 7. The detector 24 and the telescopic rod 25 are arranged on the detection movable seat 22 along the moving direction of the detection movable seat 22. Specifically:

[0058] The detection seat 22 is provided with a first mounting part 221 and a second mounting part 222. The first mounting part 221 and the second mounting part 222 are arranged along the second direction Y, and a groove 223 is provided between the first mounting part 221 and the second mounting part 222.

[0059] The detector 24 is preferably a proximity switch. The detector 24 is disposed on the first mounting part 221, and the detection end of the detector 24 extends into the groove 223.

[0060] Telescopic rods 25 are mounted on the second mounting portion 222, and each telescopic rod 25 corresponds to a detector 24. The stop end of the telescopic rod 25 protrudes from the first end of the second mounting portion 222 and is used to abut against the corresponding rivet on the workpiece 9; the test end of the telescopic rod 25 is generally retracted into the second mounting portion 222. During the test, the test end of the telescopic rod 25 can protrude from the second end of the detection movable seat 22 and move closer to or away from the detection end of the detector 24.

[0061] Since the length of the rivet before riveting is longer than its length after riveting, during testing, if the test end of the telescopic rod 25 enters the detection range of the detector 24 when the test seat 22 moves along the second direction Y, triggering the detector 24, it indicates that the rivet is not riveted properly; if the test end of the telescopic rod 25 does not enter the detection range of the detector 24 after the test seat 22 moves into place along the second direction Y, it indicates that the rivet is riveted properly.

[0062] In order to ensure that the abutting end of the telescopic rod 25 protrudes from the first end of the second mounting part 222 under normal conditions, a spring 2221 is provided in the second mounting part 222. The spring 2221 applies a potential energy to the telescopic rod 25 to move towards the tooling assembly 7.

[0063] In summary, this utility model, by placing the detection component 2 at the rear end of the riveting machine 8, facilitates the detection of whether the rivets on the workpiece 9 are properly riveted after the riveting operation, making it easier to detect defective products and ensuring the quality of the workpiece 9. By setting the first driving device 31 to drive the crossbar 33 to rotate, thereby causing all the lower pressure blocks 35 to flip up and down together, the workpiece 9 on multiple tooling components 7 can be pressed or released simultaneously. Compared with the prior art, this has the advantage of saving the number of driving devices, which helps to reduce production costs. By setting the transfer component 4, the workpiece 9 is transferred from the previous tooling component 7 to the next tooling component 7, which facilitates the riveting operation of rivets at different positions on the workpiece 9.

[0064] Finally, it should be emphasized that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
