Description

Technical Field

[0001] This utility model belongs to the field of riveting tooling technology, specifically relating to a riveting tooling for gap control. Background Technology

[0002] Riveting, also known as riveting connection, is a method of connecting multiple parts by using axial force to thicken the rivet shank inside the rivet hole and form a rivet head.

[0003] Riveting fixtures are required when riveting workpieces. However, existing riveting fixtures can only rivet one workpiece at a time, resulting in low efficiency. After multiple riveting operations, the workpiece grooves inevitably experience wear and tear. Furthermore, the riveting fixtures lack a mechanism to tighten and limit the workpiece. Therefore, if the workpiece shifts or misaligns during the riveting process, it will cause a decrease in riveting accuracy. To address this issue, we propose a gap-controlled riveting fixture. Utility Model Content

[0004] The purpose of this utility model is to provide a gap control riveting fixture to solve the problems mentioned in the background art. The existing riveting fixture can only rivet one workpiece at a time, resulting in low work efficiency. After multiple riveting operations, the workpiece groove will inevitably wear out. Furthermore, the riveting fixture does not have a mechanism to tighten and limit the workpiece. Therefore, if the workpiece is misaligned during the riveting process, it will cause a decrease in riveting accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gap-controlled riveting fixture, comprising a base, a workpiece placement plate fixedly mounted on the upper surface of the base, a plurality of workpiece contour grooves formed on the workpiece placement plate, a plurality of workpiece tops slidably disposed on the outer surface of the workpiece placement plate, a plurality of top sliding holes formed on the surface of the workpiece placement plate opposite to the plurality of workpiece contour grooves, the workpiece tops slidingly passing through the top sliding holes, one end of the workpiece top having an inclined surface, a workpiece locking ring rotatably mounted on the outer surface of the workpiece placement plate, a plurality of mating plates fixedly mounted on the inner wall of the workpiece locking ring, the side of the mating plates having an inclined surface, the inclined surface... Inclined surface one and inclined surface two fit together for use. A handle one is fixedly installed on the outer surface of the workpiece locking ring. A support column is fixedly installed on the surface of the workpiece placement plate. A sub-part placement ring and a tooling cover plate are sleeved on the outer surface of the support column. An installation plate is rotatably installed on the outer surface of the sub-part placement ring. A sub-part placement hole is opened on the sub-part placement ring at the position directly opposite the workpiece contour groove. A hand ring two is fixedly installed on the outer surface of the tooling cover plate. An elastic lever is fixedly installed on the lower surface of the tooling cover plate at the position directly opposite the workpiece contour groove and the sub-part placement hole. A bayonet is opened on the outer surface of the support column, and a tensioning plate is locked at the bayonet position. An observation hole is opened on the tooling cover plate.

[0006] The above scheme utilizes a workpiece placement plate in conjunction with a workpiece locking ring, a sub-part placement plate, and a fixture cover plate. Multiple workpiece contour grooves on the workpiece placement plate work with multiple workpiece tops, allowing for the simultaneous placement of multiple workpieces. The rotation of the workpiece locking ring drives the mating plate, which in turn utilizes the second inclined surface of the mating plate and the first inclined surface of the workpiece top to move the workpiece top into the contour groove, ensuring uniform clamping of multiple workpieces against the wall. This guarantees consistent angle stability during riveting, preventing deviations that could reduce riveting accuracy. The fixture cover plate, in conjunction with elastic levers, further aligns the workpieces, enhancing placement and clamping stability. The fixture cover plate can be position-limited via a tension plate, which locks in place by engaging with a locking slot and using a locking rod inserted into a locking groove, facilitating overall assembly.

[0007] In a preferred embodiment, a fixing ring is fixedly installed on the outer surface of the base, and an arc-shaped sliding hole is provided on the fixing ring. A fixing screw is fixedly installed on the lower surface of the workpiece locking ring, and the fixing screw passes through the arc-shaped sliding hole and is threaded with a fixing nut.

[0008] The above solution utilizes a fixing screw that passes through an arc-shaped sliding hole in conjunction with a fixing nut. When the fixing nut is unscrewed, the workpiece locking ring unlocks and can rotate. After rotation, the fixing nut is screwed on to achieve position compression locking. The structure is simple and the operation is convenient.

[0009] In a preferred embodiment, a plurality of guide seats are fixedly installed on the outer surface of the workpiece placement plate, a sliding rod is fixedly installed on the inner wall of the guide seat, a sliding block is slidably installed on the outer surface of the sliding rod, a spring is fixedly installed between the sliding block and the inner wall of the guide seat, and the sliding block is fixedly installed on the surface of the workpiece top at the corresponding position.

[0010] By using the above scheme, the guide seat and sliding rod work together to ensure the stable sliding of the sliding block, thereby ensuring the stable sliding of the workpiece top and preventing deviation. When the workpiece locking ring is rotated and the workpiece top moves toward the workpiece contour groove, the first spring will deform. Therefore, when the workpiece locking ring is rotated in the opposite direction, the elastic force of the first spring can be used to quickly push the workpiece top back to its original position, improving the ease of operation.

[0011] In a preferred embodiment, a plurality of alignment rods are fixedly installed on the upper surface of the workpiece locking ring, and a plurality of alignment holes are provided on the mounting plate, with the alignment rods inserted into the inner wall of the alignment holes.

[0012] By using the above scheme, the alignment rod and alignment hole can be used together to achieve alignment between the workpiece locking ring and the mounting plate, thus avoiding misalignment.

[0013] In a preferred embodiment, a locking block is fixedly installed on the outer surface of the tensioning plate, a locking rod is slidably installed on the locking block, a pull ring is fixedly installed at one end of the locking rod, a spring is fixedly installed between the pull ring and the locking block, and a locking groove for inserting the locking rod is opened on the surface of the tooling cover plate.

[0014] Using the above scheme, the locking rod is used in conjunction with the second spring. When the tension plate is engaged in the slot, the elastic force of the second spring can be used to drive the locking rod into the locking groove, thereby locking the position of the tension plate.

[0015] In a preferred embodiment, the bottom end of the elastic paddle has an inclined surface.

[0016] By adopting the above scheme, by setting an inclined surface on the elastic lever, the inclined surface can be used in conjunction with the elastic lever when the tooling cover plate is inserted downwards to achieve unified alignment movement of the sub-parts.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This gap control riveting fixture uses a workpiece placement plate in conjunction with a workpiece locking ring, a sub-part placement plate, and a fixture cover plate. Multiple workpiece contour grooves on the workpiece placement plate are used in conjunction with multiple workpiece tops. Multiple workpieces can be placed in the contour grooves at the same time. The rotation of the workpiece locking ring drives the mating plate to move. Then, the second inclined surface of the mating plate and the first inclined surface of the workpiece top workpiece work together to make the workpiece top workpiece move into the workpiece contour groove, so that multiple workpieces are uniformly pressed against the wall. This ensures good uniform angle stability during riveting and avoids the problem of reduced riveting accuracy due to deviation.

[0019] This gap control riveting fixture uses a fixture cover plate in conjunction with an elastic lever. The elastic lever allows for further alignment of the workpiece, thereby improving the stability of the workpiece placement and clamping. The fixture cover plate can achieve position limitation through a tension plate. The tension plate is locked in position by snapping into the bayonet and using a locking rod inserted into the locking groove, which facilitates overall assembly. Attached Figure Description

[0029] Please see Figure 1-8 This utility model provides a gap control riveting fixture, including a base 1. A workpiece placement plate 2 is fixedly installed on the upper surface of the base 1. The workpiece placement plate 2 has several workpiece contour grooves 5. Several workpiece tops 6 are slidably disposed on the outer surface of the workpiece placement plate 2. Several top sliding holes are opened on the surface of the workpiece placement plate 2 at the positions of the several workpiece contour grooves 5. The workpiece tops 6 slide through the top sliding holes. One end of the workpiece top 6 has an inclined surface. A workpiece locking ring 7 is rotatably installed on the outer surface of the workpiece placement plate 2. Several mating plates 8 are fixedly installed on the inner wall of the workpiece locking ring 7. The side of the mating plate 8 has an inclined surface. The inclined surfaces 1 and 2 are mutually fitted and used. A handle 9 is fixedly installed on the outer surface of the workpiece locking ring 7. A support column 10 is fixedly installed on the surface of the workpiece placement plate 2. A sub-part placement ring 12 and a tooling cover plate 13 are sleeved on the outer surface of the support column 10. An installation plate 11 is rotatably installed on the outer surface of the sub-part placement ring 12. A sub-part placement hole is opened on the sub-part placement ring 12 at the position directly opposite the workpiece contour groove 5. A hand ring 2 is fixedly installed on the outer surface of the tooling cover plate 13. An elastic lever 15 is fixedly installed on the lower surface of the tooling cover plate 13 at the position directly opposite the workpiece contour groove 5 and the sub-part placement hole. A bayonet is opened on the outer surface of the support column 10, and a tensioning plate 24 is clamped at the bayonet position. An observation hole is opened on the tooling cover plate 13.

[0030] By setting up a workpiece placement plate 2 in conjunction with a workpiece locking ring 7, a sub-part placement plate, and a tooling cover plate 13, multiple workpiece contour grooves 5 on the workpiece placement plate 2 are used in conjunction with multiple workpiece tops 6. Multiple workpieces can be placed in the multiple workpiece contour grooves 5 at one time. The rotation of the workpiece locking ring 7 drives the movement of the mating plate 8. Then, by using the second inclined surface of the mating plate 8 and the first inclined surface of the workpiece top 6, the workpiece top 6 moves into the workpiece contour groove 5, realizing the uniform clamping of multiple workpieces against the wall. This ensures good uniform angle stability during riveting and avoids the problem of reduced riveting accuracy due to deviation. By setting up a tooling cover plate 13 in conjunction with an elastic lever 15, the elastic lever 15 can further align the workpieces, thereby improving the stability of workpiece placement and clamping. The tooling cover plate 13 can achieve position limit through a tension plate 24. The tension plate 24 is locked in position by snapping into the bayonet and using the locking rod 4 to insert into the locking groove, which facilitates overall assembly.

[0031] A fixing ring 16 is fixedly installed on the outer surface of the base 1. The fixing ring 16 has an arc-shaped sliding hole. A fixing screw 17 is fixedly installed on the lower surface of the workpiece locking ring 7. The fixing screw 17 passes through the arc-shaped sliding hole and is threaded with a fixing nut 18. The fixing screw 17 passes through the arc-shaped sliding hole and works with the fixing nut 18. When the fixing nut 18 is unscrewed, the workpiece locking ring 7 is unlocked and can rotate. After it has rotated, the fixing nut 18 is screwed on to achieve position compression locking. The structure is simple and the operation is convenient.

[0032] Several guide seats 19 are fixedly installed on the outer surface of the workpiece placement plate 2. A sliding rod 21 is fixedly installed on the inner wall of the guide seat 19. A sliding block 20 is slidably installed on the outer surface of the sliding rod 21. A spring 22 is fixedly installed between the sliding block 20 and the inner wall of the guide seat 19. The sliding block 20 is fixedly installed on the surface of the workpiece top 6 at the corresponding position. By using the guide seat 19 and the sliding rod 21 in cooperation, the sliding block 20 can be stably slid, thereby ensuring the stable sliding of the workpiece top 6 and preventing deviation. When the workpiece locking ring 7 is rotated to move the workpiece top 6 toward the workpiece contour groove 5, the spring 22 will deform. Therefore, when the workpiece locking ring 7 is rotated in the opposite direction, the elastic force of the spring 22 can be used to quickly push the workpiece top 6 back to its original position, improving the ease of operation.

[0033] Several alignment rods 23 are fixedly installed on the upper surface of the workpiece locking ring 7. Several alignment holes are opened on the mounting plate 11. The alignment rods 23 are inserted into the inner wall of the alignment holes. By using the alignment rods 23 and the alignment holes in conjunction, the alignment between the workpiece locking ring 7 and the mounting plate 11 can be achieved, avoiding the phenomenon of offset and misalignment.

[0034] A locking block 25 is fixedly installed on the outer surface of the tension plate 24. A locking rod 4 is slidably installed on the locking block 25. A pull ring 3 is fixedly installed at one end of the locking rod 4. A spring 26 is fixedly installed between the pull ring 3 and the locking block 25. A locking groove for the locking rod 4 to be inserted is opened on the surface of the tool cover plate 13. The locking rod 4 is used in conjunction with the spring 26. When the tension plate 24 is inserted into the slot, the elastic force of the spring 26 can be used to drive the locking rod 4 into the locking groove to achieve the position locking of the tension plate 24.

[0035] The bottom end of the elastic lever 15 has an inclined surface. By setting the inclined surface on the elastic lever 15, when the tooling cover plate 13 is inserted downward, the presence of the inclined surface can be used in conjunction with the elastic lever 15 to achieve the unified alignment movement of the sub-parts.

[0036] In use, pulling the pull ring 3 drives the locking rod 4 to move and disengage from the locking groove. Pulling the tension plate 24 horizontally causes it to disengage from the bayonet. Remove the tension plate 24, pull it upwards and remove the tooling cover plate 13 and mounting plate 11. Then, place the workpieces to be riveted into the workpiece contour groove 5 respectively, and unscrew the fixing nut 18. At this time, the workpiece locking ring 7 is unlocked. The operating handle 1 9 drives the workpiece locking ring 7 to rotate, which in turn drives the mating plate 8 to rotate. When the mating plate 8 moves, it uses the inclined surface 2 to engage with the inclined surface 1 on the workpiece top 6, causing the workpiece top 6 to move towards the workpiece contour groove 5, thereby achieving the unification of multiple workpieces. Tighten the workpiece against the wall, and then tighten the fixing nut 18 to lock the workpiece locking ring 7. Then insert the mounting plate 11 into the support column 10 so that the alignment rod 23 is inserted into the alignment hole. Then place the sub-part on the sub-part placement ring 12. Then insert the tooling cover plate 13 into the support column 10. After insertion, the presence of the elastic lever 15 will uniformly align and limit the sub-part to maintain stability. Then pull the pull ring 3 to drive the locking rod 4 to disengage from the locking block 25. Insert the tension plate 24 into the bayonet of the support column 10. Use the elastic force of the second spring 26 to drive the locking rod 4 into the locking groove to complete the installation and locking of the tension plate 24.
