Abstract
Description
Technical Field
[0001] This utility model relates to the field of arc workpiece processing technology, and more specifically, to an arc shaping fixture driven by a cylinder. Background Technology
[0002] When machining arc-shaped workpieces, they need to be shaped to ensure that the shape and size of the arc-shaped parts are completely consistent with the design drawings or specifications. This is crucial for subsequent assembly and use, as any slight deviation may lead to a decrease in the performance or failure of the entire system. During the shaping process, burrs, scratches and other defects on the surface of the arc-shaped parts can be removed by grinding, polishing and other means, thereby improving its surface quality. During the stamping process of the product with a die, the punches on the die must be connected, so the front ends of the product cannot touch each other during the stamping process, resulting in the arc degree only reaching 40%.
[0003] In the current process of shaping arc workpieces, the arc workpiece that has been stamped to 40% completion is placed in a fixture, which then squeezes and limits the arc workpiece. The arc workpiece is then bent manually. Manual bending is slow and the labor intensity of the workers is high. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cylinder-driven arc shaping fixture, which aims to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cylinder-driven arc forming fixture, comprising a base plate, an arc top fixing block, an arc workpiece body, and an arc contour block, wherein the arc top fixing block and the arc workpiece body are both located on the top of the base plate, the outer bottom edge of the arc contour block is threadedly connected to the base plate, a pressing frame is movably arranged on one side of the arc top fixing block, and the bottom end of the pressing frame is fixedly connected to the base plate, a pressing rod is movably connected to the pressing frame through a hinge, and two cylinders are movably arranged on both the front and rear sides of the arc workpiece body, and all four cylinders are fixedly installed on the top of the base plate.
[0006] Furthermore, two limiting blocks are fixedly connected to the top of the substrate, and the opposing sides of the two limiting blocks extend into the arc-shaped workpiece body.
[0007] It can be seen that the above technical solution is used to limit the position of the arc-shaped workpiece body.
[0008] Furthermore, a bottom frame is fixedly connected to the bottom end of the substrate, and a connecting component is provided on the bottom frame. The connecting component includes two insert plates, two pressure plates, a connecting frame, a sliding plate, and locking bolts.
[0009] Furthermore, the top ends of the two insert plates are respectively fixedly connected to the two pressure plates, and the bottom ends of the two insert plates are both through the arc-shaped fixing block. The connecting frame is fixed to the two insert plates by locking bolts, and the bottom end of the connecting frame is fixedly connected to the sliding plate.
[0010] Furthermore, two sliding rods are fixedly connected inside the bottom frame, and one end of each sliding rod passes through the slide plate.
[0011] As can be seen, in the above technical solution, when the extrusion rod drives the arc-top fixed block to move horizontally, the arc-top fixed block can drive the slide plate to slide on the slide rod, thereby preventing the arc-top fixed block from deflecting when moving horizontally.
[0012] Furthermore, both insert plates are fixedly fitted with gaskets, and the bottom ends of both gaskets are in contact with the arc-shaped fixing block.
[0013] As can be seen, in the above technical solution, the gasket can improve the stability between the pressure plate and the arc-shaped fixing block.
[0014] Furthermore, four support frames are movably provided on the outer side of the bottom frame, and the top ends of the four support frames are fixedly connected to the base plate.
[0015] It can be seen that the above technical solution is designed to facilitate the support of the substrate.
[0016] The technical effects and advantages of this utility model are as follows:
[0017] 1. This utility model presses the pressing frame and moves the extrusion rod, which in turn drives the arc-top fixing block to move horizontally. The arc-top fixing block and the arc-shaped block press and fix the center position of the arc workpiece body. Then, four cylinders are activated in sequence to press and bend the arc workpiece body. The operation is simple and does not require manual bending of the arc workpiece body, which effectively improves the bending efficiency and reduces the labor intensity of the workers.
[0018] 2. This utility model involves rotating the arc-shaped contour block away from the base plate, replacing the arc-shaped contour block with one of the appropriate diameter according to the needs of the arc workpiece body, rotating the locking bolt away from the connecting frame, thereby releasing the fixation between the two insert plates and the connecting frame, moving the two pressure plates upward in sequence, and moving the two insert plates away from the arc top fixing block, and replacing the arc top fixing block with one of the appropriate diameter according to the needs of the arc workpiece body. The structure is simple and has a wide range of applications. Attached Figure Description

[0026] Refer to the instruction manual appendix Figure 1-4 This embodiment of a cylinder-driven arc shaping fixture includes a base plate 1, an arc top fixing block 4, an arc workpiece body 6, and an arc contour block 7. The arc top fixing block 4 and the arc workpiece body 6 are both located on the top of the base plate 1. The outer bottom edge of the arc contour block 7 is threadedly connected to the base plate 1. A pressing frame 2 is movably arranged on one side of the arc top fixing block 4, and the bottom end of the pressing frame 2 is fixedly connected to the base plate 1. A pressing rod 3 is movably connected to the pressing frame 2 through a hinge. Two cylinders 8 are movably arranged on both the front and rear sides of the arc workpiece body 6, and all four cylinders 8 are fixedly installed on the top of the base plate 1.
[0027] Furthermore, two limiting blocks 9 are fixedly connected to the top of the substrate 1, and the opposing sides of the two limiting blocks 9 extend into the arc-shaped workpiece body 6.
[0028] Furthermore, a bottom frame 11 is fixedly connected to the bottom end of the substrate 1. A connecting component 5 is provided on the bottom frame 11. The connecting component 5 includes two insert plates 501, two pressure plates 502, a connecting frame 503, a sliding plate 504, and a locking bolt 505. The top ends of the two insert plates 501 are fixedly connected to the two pressure plates 502 respectively, and the bottom ends of the two insert plates 501 pass through the arc-shaped top fixing block 4. The connecting frame 503 is fixed to the two insert plates 501 by the locking bolt 505, and the bottom end of the connecting frame 503 is fixedly connected to the sliding plate 504. Two sliding rods 506 are fixedly connected inside the bottom frame 11, and one end of each sliding rod 506 passes through the sliding plate 504. A gasket 507 is fixedly sleeved on each of the two insert plates 501, and the bottom ends of the two gaskets 507 are in contact with the arc-shaped top fixing block 4.
[0029] In this process, the arc-shaped contour block 7 is rotated and moved away from the base plate 1. The arc-shaped contour block 7 of the corresponding diameter is replaced according to the needs of the arc workpiece body 6. The locking bolt 505 is rotated and moved away from the connecting frame 503, thereby releasing the fixation between the two insert plates 501 and the connecting frame 503. The two pressure plates 502 are moved upward in sequence, and the two insert plates 501 are moved away from the arc top fixing block 4.

Similarly, the arc top fixing block 4 is installed. The shim 507 can improve the stability between the pressure plate 502 and the arc top fixing block 4. At the same time, when the extrusion rod 3 drives the arc top fixing block 4 to move horizontally, the arc top fixing block 4 can drive the slide plate 504 to slide on the slide rod 506, thereby preventing the arc top fixing block 4 from deflecting when moving horizontally.

Simultaneously, two limiting blocks 9 limit the arc-shaped workpiece body 6. Then, the operator presses the pressing frame 2, causing the extrusion rod 3 to move. The extrusion rod 3 drives the arc-top fixing block 4 to move horizontally. The arc-top fixing block 4 and the arc-shaped contour block 7 then extrude and fix the center position of the arc-shaped workpiece body 6. Next, four cylinders 8 are activated sequentially. It is worth noting that each of the four cylinders 8 has a circular extrusion block fixedly installed at one end near the arc-shaped workpiece body 6. The four circular extrusion blocks sequentially extrude and bend the arc-shaped workpiece body 6. The operation is simple, requiring no manual bending of the arc-shaped workpiece body 6, effectively improving bending efficiency and reducing the labor intensity of the operator.
