Description

Technical Field

[0001] This utility model relates to a stamping and riveting fixture, and more particularly to a combined precision sheet metal stamping and riveting fixture, belonging to the field of sheet metal processing technology. Background Technology

[0002] Sheet metal processing is a metal processing technology that uses stamping, shearing, bending, welding and other processes to manufacture parts and structures that meet the requirements. Sheet metal processing involves many aspects such as material selection, process flow, equipment use and application fields. When it is necessary to splice metal sheets, riveting is usually used for fixing.

[0003] When using stamping and riveting fixtures to process sheet metal parts, the fixtures do not have the function of supporting and moving the sheet metal parts. The sheet metal riveting process is carried out manually by holding the sheet metal parts for support and position adjustment to meet the stamping and riveting requirements at different positions on the sheet metal parts. This method is not stable and precise enough, and it is easy for the position of the sheet metal riveting to deviate, which reduces the quality of sheet metal riveting processing. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a combined precision sheet metal stamping and riveting fixture that can stably and accurately support and transfer sheet metal parts.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A combined precision sheet metal stamping and riveting fixture includes a processing table, on which a riveting head is mounted. A support block is mounted on the processing table below the riveting head. An automatic transfer mechanism is provided on the processing table. The automatic transfer mechanism includes two first slide rails symmetrically fixedly mounted on the processing table, with a first placement platform slidably mounted between the two first slide rails. Two first fixing plates are symmetrically fixedly mounted on the surface of the processing table, and a first lead screw is movably mounted between the two first fixing plates. A first motor is mounted at one end of the first lead screw, and a first moving block connected to the bottom of the first placement platform is mounted on the first lead screw. Two second slide rails are symmetrically fixedly mounted on the top of the first placement platform, with a second placement platform slidably mounted between the two second slide rails. Two second fixing plates are symmetrically fixedly mounted on the surface of the second slide rails, and a second lead screw is movably mounted between the two second fixing plates. A second motor is mounted at one end of the second lead screw, and a second moving block connected to the bottom of the second placement platform is mounted on the second lead screw. Two limiting plates are symmetrically mounted on the top of the second placement platform, and a first support plate parallel to the support block is fixedly mounted on one side of each limiting plate.

[0007] Furthermore, a second support plate is fixedly installed on the top of the limiting plate, and a screw rod connected by threads is provided on the second support plate. A pressure plate that is slidably connected to the screw rod is slidably installed on the limiting plate.

[0008] Furthermore, a first fixing block is fixedly installed on both sides of the first moving block and the second moving block, and a sponge is provided on one side of the first fixing block to fit against the first lead screw and the second lead screw.

[0009] Furthermore, two first springs are symmetrically installed inside the first fixing block, and a locking rod is fixedly installed at one end of the first spring. A locking block is fixedly installed on the sponge.

[0010] Furthermore, the diameter of the lever matches the inner diameter of the slot on the lever block, and one end of the lever is arc-shaped.

[0011] Furthermore, the limiting plate is movably installed on the top of the second placement platform, and a second fixing block is fixedly installed on both sides of the limiting plate. A limiting rod is movably installed on the second fixing block, and multiple positioning blocks are uniformly fixedly installed on the surface of the second placement platform.

[0012] Furthermore, a second spring is fixedly installed on the top of the second fixing block, and the second spring is sleeved on the limiting rod and one end is connected to the top of the limiting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This application, through the setting of an automatic transfer mechanism, can support and transfer sheet metal parts. The sheet metal parts are placed on two limit plates and a first support plate for support. The first motor and the second motor are started to drive the first lead screw and the second lead screw to rotate, which in turn drives the first moving block and the second moving block to move. The first moving block and the second moving block, in cooperation with the first slide rail and the second slide rail, drive the first placement platform and the second placement platform to move, thereby adjusting the longitudinal and lateral transfer of the sheet metal parts. This allows the riveting joint to be riveted gradually at different positions on the sheet metal. The transfer process is smooth and precise, which can replace manual hand-held sheet metal stamping and riveting processing, effectively avoids deviations in the riveting position, and helps to improve the quality of riveting processing.

[0021] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figures 1-5The diagram shows a combined precision sheet metal stamping and riveting fixture, comprising a processing table 1, a riveting head 2 mounted on the processing table 1, a support block 3 mounted on the processing table 1 below the riveting head 2, and an automatic transfer mechanism 4 mounted on the processing table 1. The automatic transfer mechanism 4 includes two first slide rails 5 symmetrically fixedly mounted on the processing table 1, a first placement platform 6 slidably mounted between the two first slide rails 5, two first fixing plates 7 symmetrically fixedly mounted on the surface of the processing table 1, a first lead screw 8 movably mounted between the two first fixing plates 7, a first motor 9 mounted at one end of the first lead screw 8, and a component mounted on the first lead screw 8 that is connected to the bottom of the first placement platform 6. The first movable block 10 is connected; two second slide rails 11 are symmetrically fixedly installed on the top of the first placement platform 6, and a second placement platform 12 is slidably installed between the two second slide rails 11. Two second fixed plates 13 are symmetrically fixedly installed on the surface of the second slide rails 11, and a second lead screw 14 is movably installed between the two second fixed plates 13. A second motor 15 is installed at one end of the second lead screw 14, and a second movable block 16 connected to the bottom of the second placement platform 12 is installed on the second lead screw 14; two limiting plates 17 are symmetrically installed on the top of the second placement platform 12, and a first support plate 18 parallel to the support block 3 is fixedly installed on one side of the limiting plate 17. The automatic transfer mechanism 4 supports and transfers sheet metal parts. The sheet metal parts are placed on two limit plates 17 and a first support plate 18 for support. Then, the first motor 9 and the second motor 15 are started to drive the first lead screw 8 and the second lead screw 14 to rotate, which in turn drives the first moving block 10 and the second moving block 16 to move. The first moving block 10 and the second moving block 16, in cooperation with the first slide rail 5 and the second slide rail 11, drive the first placement platform 6 and the second placement platform 12 to move, thereby adjusting the longitudinal and lateral transfer of the sheet metal parts. This allows the riveting joint 2 to be riveted gradually at different positions on the sheet metal. The transfer process is smooth and precise.

[0023] In this embodiment, if Figures 1-5As shown, a second support plate 19 is fixedly installed on the top of the limiting plate 17. A screw 20 connected by a thread is provided on the second support plate 19. A pressure plate 21 that is slidably connected to the screw 20 is slidably installed on the limiting plate 17. A first fixing block 22 is fixedly installed on both sides of the first moving block 10 and the second moving block 16. A sponge wiper 23 that fits against the first lead screw 8 and the second lead screw 14 is provided on one side of the first fixing block 22. Two first springs 24 are symmetrically installed inside the first fixing block 22. A locking rod 25 is fixedly installed on one end of the first spring 24. A locking block 26 is fixedly installed on the sponge wiper 23. After the sheet metal part is placed on the first support plate 18, the screw 20 is rotated, and the thread between it and the second support plate 19 drives the pressure plate 21 to descend, so that the pressure plate 21 cooperates with the first support plate 18 to clamp the sheet metal part, making the sheet metal part more stably supported on the two first support plates 18, further preventing shaking during riveting; during the movement of the first moving block 10 and the second moving block 16, the sponge wipers 23 on both sides can wipe the surfaces of the first lead screw 8 and the second lead screw 14, and clean the surfaces of the first lead screw 8 and the second lead screw 14. The surface of 4 serves a cleaning function, preventing impurities and dust from adhering to the surfaces of the first lead screw 8 and the second lead screw 14, which could affect the connection and movement of the first moving block 10 and the second moving block 16. The first fixed block 22 and the sponge 23 are connected and fixed by the engagement of the locking rod 25 and the locking block 26. Since the locking rod 25 is supported by the first spring 24, the locking rod 25 can extend and retract in the first fixed block 22, thereby allowing the locking rod 25 to separate from the locking block 26, making it easy to remove the sponge 23 from the first fixed block 22.

[0024] In this embodiment, if Figures 1-5As shown, the diameter of the locking rod 25 matches the inner diameter of the slot on the locking block 26, and one end of the locking rod 25 is arc-shaped; the limiting plate 17 is movably installed on the top of the second placement platform 12, and the two sides of the limiting plate 17 are fixedly installed with second fixing blocks 27, and the second fixing blocks 27 are movably installed with limiting rods 29. Multiple positioning blocks 30 are evenly fixedly installed on the surface of the second placement platform 12; the top of the second fixing block 27 is fixedly installed with a second spring 28, and the second spring 28 is sleeved on the limiting rod 29 and one end is connected to the top of the limiting rod 29. The diameter of the locking rod 25 is matched with the inner diameter of the slot on the locking block 26, making the engagement between the locking rod 25 and the locking block 26 more secure and effectively preventing the sponge 23 from shaking. At the same time, one end of the locking rod 25 is made arc-shaped, making it easier for the locking block 26 to squeeze the locking rod 25 during disassembly and engagement. Since the limiting plate 17 is movably set on the top of the second placement platform 12, the position of the limiting plate 17 can be adjusted to change the distance between the two limiting plates 17, which facilitates the placement and fixing of sheet metal parts of different specifications. After adjustment, the limiting rod 29 can be inserted into the positioning block 30 to limit and fix the limiting plate 17. Under the contraction support of the second spring 28, the stability of the limit can be improved, preventing the limiting rod 29 from detaching from the positioning block 30.

[0025] The working process of the combined precision sheet metal stamping and riveting fixture provided in this embodiment is as follows:

[0026] The sheet metal part is placed on two limiting plates 17 and a first support plate 18 for support. The first motor 9 and the second motor 15 are started to drive the first lead screw 8 and the second lead screw 14 to rotate respectively, which in turn drive the first moving block 10 and the second moving block 16 to move. With the cooperation of the first moving block 10 and the second moving block 16 with the first slide rail 5 and the second slide rail 11, the first placement platform 6 and the second placement platform 12 are moved. The sheet metal part is moved and adjusted longitudinally and laterally, so that the riveting joint 2 is riveted gradually at different positions on the sheet metal. The moving process is smooth and precise.
