Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically a positioning tooling for welded pipe processing. Background Technology

[0002] When welding pipes, a positioning fixture is needed to clamp and position them. Utility model patent CN214602895U discloses a pipeline welding positioning fixture, including a support platform, a fixing bracket for fixing the pipe to be welded, and an orienting device for fixing the valve to be welded. The valve to be welded has an actuator interface. The fixing bracket is fixedly connected to the support platform. The support platform has a valve positioning point preset, and several sets of fixing holes for fixing the orienting device are arranged circumferentially around the valve positioning point. The orienting device includes a base plate detachably fixed to the fixing hole set and an orienting plate fixedly connected to the base plate. The orienting plate has a fixing slot for fixing the actuator interface. The actuator interface is inserted into the fixing slot to fix the valve to be welded on the support platform. This pipeline welding positioning fixture positions both the valve to be welded and the pipe to be welded, ensuring that the actuator interface of the valve to be welded is accurately located in the preset position, effectively preventing the actuator interface from occupying the installation space of other components.

[0003] However, when using this device, it is not convenient to adjust the angle of the welded pipes according to the usage requirements for welding connection. At the same time, there is a certain gap between the two welded pipes during the welding process, which affects the tightness of the weld. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning fixture for welded pipe processing, which solves the problems that when the device is in use, it is not convenient to adjust the angle of the welded pipe according to the usage requirements for welding connection, and at the same time, there is a certain gap between the two welded pipes during the welding process, which affects the welding tightness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for welded pipe processing, comprising a base plate, a sliding plate slidably connected to the upper end of the base plate, an adjusting mechanism provided on the base plate, a support plate fixedly connected to the upper end of the sliding plate, an adjusting mechanism provided on the support plate, a slide frame provided on the adjusting mechanism, a clamping plate slidably connected to the outer side of the slide frame, a screw threadedly connected to the inside of the slide frame, and the screw and the clamping plate connected by bearings.

[0006] Preferably, the adjusting mechanism includes a bidirectional screw, which is movably connected inside the slide plate. A limiting plate is fixedly connected to the upper end of the base plate, and the limiting plate and the bidirectional screw are slidably connected. A top plate is threadedly connected to the outer side of the bidirectional screw, and the top plate and the base plate are slidably connected. A compression spring is provided on the outer side of the bidirectional screw. By rotating the bidirectional screw and the top plate to perform threaded movement, the compression spring compresses the slide plate, thereby maintaining contact between the two welded pipes clamped and fixed by the clamping plate, preventing gaps from existing between the two welded pipes after adjustment, which would affect the welding tightness of the welded pipes.

[0007] Preferably, a dovetail block is fixedly connected to the lower end of the top plate, and the dovetail block is slidably connected to the bottom plate. The dovetail block guides the movement of the top plate.

[0008] Preferably, one end of the compression spring is fixedly connected to the top plate, and the other end of the compression spring is fixedly connected to the slide plate. By setting the compression spring, the slide plate is elastically compressed.

[0009] Preferably, the adjusting mechanism includes a support rod, with the upper end of the support plate fixedly connected to the support rod. A fixed plate is hinged to the upper end of the support rod, and the fixed plate is fixedly connected to the slide. A cylinder is fixedly mounted on the surface of the support plate, with its cylinder rod passing through and slidably connected to the support plate. An adjusting plate is fixedly connected to the end of the cylinder rod, and the adjusting plate is slidably connected to the support plate. The cylinder drives the adjusting plate to slide on the support plate, thereby changing the angle of the adjusting rod, which in turn changes the angle of the fixed plate, and consequently, the angle between the two welded pipes. This allows the fixed angle between the two welded pipes to be adjusted according to welding requirements.

[0010] Preferably, an adjusting rod is hinged to the upper end of the adjusting plate, and the adjusting rod is hinged to the fixed plate. The adjusting rod allows for adjustment and support of the fixed plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses the rotation of the bidirectional screw and the top plate to make threaded movement, which causes the compression spring to squeeze the slide plate, thereby keeping the two welded pipes fixed by the clamping plate in contact, avoiding gaps between the two welded pipes after adjustment, which would affect the welding tightness of the welded pipes.

[0013] 2. This utility model uses a cylinder to drive an adjusting plate to slide on a support plate, thereby changing the angle of the adjusting rod, which in turn changes the angle of the fixed plate, and thus changes the angle between the two welded pipes. This allows the fixed angle between the two welded pipes to be adjusted according to welding requirements. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 , Figure 3 , Figure 4 A positioning fixture for welded pipe processing includes a base plate 1, a slide plate 2 slidably connected to the upper end of the base plate 1, an adjusting mechanism 3 provided on the base plate 1, a support plate 4 fixedly connected to the upper end of the slide plate 2, an adjusting mechanism 5 provided on the support plate 4, a slide frame 6 provided on the adjusting mechanism 5, a clamping plate 7 slidably connected to the outer side of the slide frame 6, and a screw 8 threadedly connected to the inside of the slide frame 6. The screw 8 and the clamping plate 7 are connected by bearings.

[0021] Please see Figure 1 , Figure 2The adjusting mechanism 3 includes a bidirectional screw 31. The bidirectional screw 31 is movably connected inside the slide plate 2. A limiting plate 32 is fixedly connected to the upper end of the base plate 1. The limiting plate 32 and the bidirectional screw 31 are slidably connected. A top plate 33 is threadedly connected to the outside of the bidirectional screw 31. The top plate 33 and the base plate 1 are slidably connected. A dovetail block 34 is fixedly connected to the lower end of the top plate 33. The dovetail block 34 and the base plate 1 are slidably connected. The dovetail block 34 guides the movement of the top plate 33. A compression spring 35 is provided on the outside of the bidirectional screw 31. One end of the compression spring 35 is fixedly connected to the top plate 33, and the other end of the compression spring 35 is fixedly connected to the slide plate 2. The compression spring 35 makes the slide plate 2 elastically compressed. By rotating the bidirectional screw 31 and the top plate 33 to make threaded movements, the compression spring 35 squeezes the slide plate 2, thereby keeping the two welded pipes clamped and fixed by the clamping plate 7 in contact, avoiding gaps after the two welded pipes are adjusted, which would affect the welding tightness of the welded pipes.

[0022] Please see Figure 1 , Figure 3 , Figure 4 The adjusting mechanism 5 includes a support rod 51. The upper end of the support plate 4 is fixedly connected to the support rod 51. The upper end of the support rod 51 is hinged to a fixed plate 52. The fixed plate 52 is fixedly connected to the slide 6. The upper end of the support plate 4 is fixedly connected to a support plate 53. A cylinder 54 is fixedly mounted on the surface of the support plate 53. The cylinder rod of the cylinder 54 passes through the support plate 53 and is slidably connected to the support plate 53. An adjusting plate 55 is fixedly connected to the end of the cylinder rod of the cylinder 54. The adjusting plate 55 is slidably connected to the support plate 4. An adjusting rod 56 is hinged to the upper end of the adjusting plate 55. The adjusting rod 56 is hinged to the fixed plate 52. By setting the adjusting rod 56, the fixed plate 52 is supported and adjusted. The cylinder 54 drives the adjusting plate 55 to slide on the support plate 4, thereby changing the angle of the adjusting rod 56, which in turn changes the angle of the fixed plate 52, and thus changes the angle between the two welded pipes. This allows the fixed angle between the two welded pipes to be adjusted according to welding requirements.

[0023] The specific implementation process of this utility model is as follows: In use, according to the adjustment device for the butt joint angle between the two welded pipes, the cylinder 54 is activated. The cylinder 54 drives the cylinder rod to extend, and the cylinder rod drives the adjusting plate 55 to move. The movement of the adjusting plate 55 causes the adjusting rod 56 to deflect, which in turn causes the adjusting rod 56 to change the angle of the fixing plate 52. The cylinder 54 drives the adjusting plate 55 to slide on the support plate 4, which in turn causes the angle of the adjusting rod 56 to change, which in turn causes the angle of the fixing plate 52 to change, which in turn causes the angle between the two welded pipes to change. Thus, the fixed angle between the two welded pipes can be adjusted according to the welding requirements. Then, the steel pipe is placed between the fixing plate 52 and the clamping plate 7, and the screw 8 is manually rotated. The rotation of the screw 8 and the slide 6 make a... The threaded movement causes the clamping plate 7 to move, and the distance between the clamping plate 7 and the fixing plate 52 changes, thus fixing the steel pipe in place. Then, the double-acting screw 31 and the top plate 33 are manually rotated to make threaded movement, which causes the top plate 33 to compress the compression spring 35. The compression spring 35 drives the sliding plate 2 to move, which changes the gap between the two sliding plates 2, thus shortening the distance between the two welded pipes and maintaining contact. At the same time, the continuous movement of the top plate 33 compresses the compression spring 35. By rotating the double-acting screw 31 and the top plate 33 to make threaded movement, the compression spring 35 compresses the sliding plate 2, thus maintaining contact between the two welded pipes clamped and fixed by the clamping plate 7, preventing gaps from existing after the two welded pipes are adjusted, which would affect the welding tightness of the welded pipes.
