Technical Field
[0001] The utility model relates to the technical field of welding fixtures, in particular to a rotary welding fixture. Background Art
[0002] A fixture is a device used to fix the object to be processed during the mechanical manufacturing process so that it occupies the correct position for construction or inspection. When sealing a round tube or welding a round tube to the surface of a round plate, a fixture is required to clamp and lock the round tube or round plate, and the two can be driven by the fixture to rotate for welding.
[0003] Traditional clamps can only clamp and lock the round tube from the outside or inside, and then put the round plate against the top of the round tube to lock and weld. However, the sizes of round tubes are different, and the single inner support or external clamping structure cannot meet the requirements of clamping large and small diameter round tubes at the same time. In addition, there is a need to place the round tube on the top and the round plate on the bottom to be locked, and traditional clamps cannot meet the use requirements. Therefore, we propose a rotary welding clamp. Utility Model Content
[0004] The purpose of the utility model is to provide a rotary welding fixture, which can clamp and lock a round tube with a large diameter by using a clamping plate, and lock a round tube with a small diameter by using a vertical rod from the inside, or clamp and lock a circular plate by using a clamping plate, and then place the circular plate or the circular tube on top and lock it tightly with a cone block, so as to meet the needs of clamping circular tubes with different diameters, or place the circular plate at the bottom and the circular tube at the top and lock it, so as to meet different clamping and locking requirements and solve the problems raised in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rotary welding fixture, comprising a base and an upper plate, the upper plate being horizontally placed above the base, and support rods are fixed between the four corners of the bottom of the upper plate and the base as vertical supports; an electric turntable is installed and fixed in the middle position of the surface of the base, and three first cylinders are installed on the outer ring of the surface of the electric turntable through side plates, a clamp is fixed at the end of the first cylinder, a horizontal support plate is welded and fixed to the bottom of the clamp, and a vertical rod is vertically fixed to the outer position of the surface of the support plate; a second cylinder is installed in the middle position of the surface of the upper plate, a lifting plate is fixed to the bottom end of the second cylinder, and a cone block is rotatably installed in the middle position of the bottom of the lifting plate.
[0006] By adopting the above technical scheme, when the round tube is placed at the bottom for locking, the vertical support of the round tube is placed above the support plate, and the first cylinder drives the clamp to be pushed out, so that the clamp clamps and locks the round tube with a large diameter from the outside. When the first cylinder drives the clamp to be retracted, it can push the support round tube from the inside to the outside of the round tube to lock the round tube with a small diameter, and then the round plate is aligned and placed above the round tube, and is locked by the cone block for welding. The round plate can also be placed at the bottom and clamped by the clamp, and the round tube is placed above it and locked by the cone block above from the inside for welding.
[0007] Optionally, a rubber pad is fixed to the inner surface of the clamping plate, and the rubber pad is fixed to the surface of the clamping plate by fitting.
[0008] By adopting the above technical solution, when the clamping plate clamps the round tube or round plate from the outside, the rubber pad contacts the outer surface of the round tube or round plate, thereby achieving an anti-slip locking effect.
[0009] Optionally, a rubber sleeve is fixedly sleeved on the outer ring of the vertical rod, and the inner ring of the rubber sleeve is pressed tightly against the outer surface of the vertical rod.
[0010] By adopting the above technical solution, when the vertical rod contacts the inner ring of the round tube from the inside, it is pressed against the inner surface of the round tube through the rubber sleeve, which has an anti-slip locking effect on the clamping of the round tube.
[0011] Optionally, the bottom of the cone block is set to be a plane, and the diameter of the bottom of the cone block is smaller than the diameter above it.
[0012] By adopting the above technical solution, the bottom of the flat cone block can be pressed against the surface of the circular plate, and the setting that the lower diameter is smaller than the upper diameter can press and lock circular tubes with different inner diameters from the inside.
[0013] Optionally, the second cylinder and the cone block are located directly above the center position of the electric turntable.
[0014] By adopting the above technical solution, it is ensured that the cone block can be pressed against the center of the circular plate, or just pressed against the inside of the circular tube and locked.

[0016] 1. The technical solution of the present application is to install three first cylinders with clamps fixed at the ends on the surface of the electric turntable, the bottom of the clamps is transversely fixed to the support plate, and a vertical rod is vertically fixed to the outer position of the support plate surface. The clamps can be used to clamp and lock round tubes with large diameters, and the vertical rods can be used to contact and lock round tubes with small diameters from the inside, or the clamps can be used to clamp and lock the circular plates, and then the circular plates or the circular tubes are placed on top and locked by the cone blocks, so as to meet the needs of clamping circular tubes with different diameters, or the circular plates can be placed at the bottom and the circular tubes are placed at the top and locked, so as to meet different clamping and locking requirements.
[0017] 2. The technical solution of the present application sets the bottom surface of the cone block to be a plane, which is convenient for contacting the surface of the circular plate, thereby pressing and locking the circular plate on the surface of the circular tube, and making it convenient for contacting and supporting circular tubes of different diameters from the inside.

[0022] See also Figure 1-2 The utility model provides a technical solution: a rotary welding fixture, including a base 1 and an upper plate 2, characterized in that the upper plate 2 is horizontally placed above the base 1, and support rods 21 are vertically fixed between the four corners of the bottom of the upper plate 2 and the base 1, and four support rods 21 are provided, and the lengths of the four support rods 21 are the same, so that the upper plate 2 can be supported in parallel directly above the base 1.
[0023] An electric turntable 11 is fixedly installed in the middle position of the surface of the base 1, and three first cylinders 3 are installed on the outer ring of the surface of the electric turntable 11 through the side plate 111. The first cylinders 3 are evenly installed around the surface of the electric turntable 11, and a clamp 31 is fixed to the end of the first cylinder 3, and a rubber pad 311 is fixed to the inner surface of the clamp 31. When the clamp 31 is driven by the first cylinder 3 to move toward the center, the rubber pad 311 can be used to contact the outer surface of the round tube or round plate to clamp and lock it. A horizontal support plate 32 is welded and fixed to the bottom of the clamp 31, and when the round tube is placed but not locked, the round tube can be supported from the bottom.
[0024] A vertical rod 33 is vertically fixed to the outside of the support plate 32 surface, and a rubber sleeve 331 is fixed on the outer ring of the vertical rod 33. The inner ring of the rubber sleeve 331 is pressed against the outer surface of the vertical rod 33. When the vertical rod 33 is driven by the first cylinder 3 from the inside to be retracted to the outside, the rubber sleeve 331 can be pressed against the inner surface of the round tube to support and lock the round tube from the inside. In addition, when supporting the circular plate before clamping and locking it, the circular plate can be supported on the top of the vertical rod 33.
[0025] A second cylinder 4 is installed in the middle position of the surface of the upper plate 2, and a lifting plate 41 is fixed to the bottom end of the second cylinder 4. A cone block 411 is rotatably installed in the middle position of the bottom of the lifting plate 41. The second cylinder 4 and the cone block 411 are located directly above the center position of the electric turntable 11. The bottom of the cone block 411 is set to be a plane. The bottom diameter of the cone block 411 is smaller than the diameter above it. The plane at the bottom of the cone block 411 can be pressed against the middle position of the surface of the circular plate to lock it, and the bottom of the cone block 411 can be supported by the inside of the circular tube to lock the top of the circular tube.
[0026] When in use, the first cylinder 3 and the second cylinder 4 are both connected to the high-pressure gas source through the electromagnetic control valve. When the round tube is placed at the bottom and welded with the round plate, the round tube is placed above the three support plates 32 for support, and then the first cylinder 3 is controlled to drive the clamping plate 31 to push it out, so that the clamping plate 31 can be clamped against the outer surface of the round tube through the rubber pad 311 on its inner surface, and the round tube can be clamped from the outer ring, and a round tube with a relatively large diameter can be clamped; conversely, the first cylinder 3 is controlled to drive the clamping plate 31 to be retracted toward the side plate 111, so that the vertical rod 33 can be pressed against the inner ring of the round tube from the inside through the rubber sleeve 331 The surface can be stretched out from the inside to support the round tube, which can be suitable for locking round tubes with smaller diameters; then the round plate is aligned and placed on the upper surface of the round tube, and the second cylinder 4 is controlled to drive the lifting plate 41 and drive the cone block 411 to lower the height, so that the flat support at the bottom of the cone block 411 is in contact with the surface of the round plate, and the two are tightly locked, and then the round tube and the round plate can be welded. During the welding process, the electric turntable 11 is controlled to drive the upper structure to rotate, which can drive the round tube to rotate, and make the round plate rotate synchronously under the resistance of the cone block 411, and then the four sides of the two can be welded. When it is necessary to weld the circular tube to the surface of the circular plate and place the circular plate below, the circular plate support can be supported by the top of the vertical rod 33 placed on the surface of the support plate 32, and then the first cylinder 3 is controlled to drive the clamping plate 31 to be pushed out, so that the clamping plate 31 can be clamped and pressed against the outer surface of the circular plate through the rubber pad 311 on its inner surface, and the circular plate can be clamped and locked, and then the vertical support of the circular tube is aligned and placed on the surface of the circular plate, and then the second cylinder 4 is controlled to drive the lifting plate 41 and the cone block 411 to lower the height, so that the cone block 411 can press against the inside of the circular tube from the inside and press against the inner surface of the circular tube from the inside, so that the circular tube can be pressed against the surface of the circular plate, and then the circular tube can be welded to the surface of the circular plate. During the welding process, the electric turntable 11 is also controlled to drive the upper structure to rotate, which can drive the circular plate to rotate, and make the circular tube rotate synchronously under the action of the cone block 411, and then the four sides of the two can be welded.
