Description

Technical Field

[0001] The utility model relates to the technical field of welding jigs, and specifically relates to a clamping jig for welding a pressure vessel assembly. Background Technique

[0002] During the welding process of a pressure vessel assembly, a clamping jig is required. The patent publication number is CN217750171U, which discloses a welding jig for a pressure vessel assembly, including a bottom plate and a support frame vertically fixed on the top of the bottom plate. The top of the support frame is connected with a jig plate through a bearing. Device holes are formed on the jig plate, and two clamping plates that can approach or move away from each other are arranged in the device holes. Two abutting plates are arranged on the upper and lower sides of the jig plate, and through holes are formed on the abutting plates. A pressing component for forcing the abutting plates to move towards one side of the jig plate is arranged between the jig plate and the abutting plates. In the welding jig for a pressure vessel assembly of the utility model, when in use, the pressure vessel is placed into the device hole, and it can be clamped and fixed by the mutual approach of the two clamping plates. Then, the components to be welded are placed at both ends of the pressure vessel, and the abutting plates are driven by the pressing component to abut and fix the components, so as to stably fit the arc-shaped pressure vessel assembly together.

[0003] The above-mentioned prior art solution has the following defects: The angle of the jig plate is positioned through the insertion and matching of a limiting hole and a limiting rod. However, there are regular intervals between the limiting holes, and a stepped adjustment will be formed during the adjustment of the jig plate. When the angle that the jig plate needs to be adjusted is between the limiting holes, the cooperation of the limiting hole and the limiting rod will not be able to meet the angle positioning of the jig plate, reducing the angle adjustment effect of the clamping jig. Content of the Utility Model

[0004] To solve the problems raised in the above background technique, the purpose of the present utility model is to provide a clamping jig for welding a pressure vessel assembly, which has the advantage of stepless adjustment, and solves the problem that the angle of the jig plate is positioned through the insertion and matching of a limiting hole and a limiting rod. However, there are regular intervals between the limiting holes, and a stepped adjustment will be formed during the adjustment of the jig plate. When the angle that the jig plate needs to be adjusted is between the limiting holes, the cooperation of the limiting hole and the limiting rod will not be able to meet the angle positioning of the jig plate, reducing the angle adjustment effect of the clamping jig.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A clamping tool for welding a pressure vessel assembly, including a U-shaped plate. A tooling plate is provided at the top inside the U-shaped plate. A clamping tooling assembly is fixedly connected to the surface of the tooling plate. Rotating shafts are fixedly connected to both sides of the tooling plate. The outer sides of the rotating shafts penetrate to the outside of the U-shaped plate. An infinitely variable locking wheel is fixedly connected to the surface of the rotating shafts. A clamping locking plate is provided outside the infinitely variable locking wheel. The clamping locking plate is movably connected to the outside of the U-shaped plate through a hinge. A pushing mechanism is provided at the bottom inside the clamping locking plate.

[0006] Preferably, the pushing mechanism includes a mounting frame. The mounting frame is fixedly connected to the bottom inside the U-shaped plate. A motor is fixedly connected to the top of the mounting frame. The output end of the motor penetrates to the inside of the mounting frame. A rotating plate is fixedly connected to the output end of the motor. Moving plates are provided on both sides of the rotating plate. Push rods are fixedly connected to the outside of the moving plates. The outer sides of the push rods penetrate to the outside of the U-shaped plate.

[0007] Preferably, sliding rods are fixedly connected to both the front side and the rear side inside the U-shaped plate. The moving plates are slidably connected to the surfaces of the sliding rods.

[0008] Preferably, a stabilizing sleeve is sleeved on the surface of the sliding rod. The surface of the stabilizing sleeve is fixedly connected to the surface of the moving plate.

[0011] Preferably, pulleys are rotatably connected to both sides of the rotating plate. The surfaces of the pulleys are in contact with the surfaces of the moving plates.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. In the present utility model, the rotating plate is rotated by a motor. The rotating plate is inclined, and the rotating plate loses the supporting effect on the moving plate and the push rod. After the push rod becomes loose, the push rod loses the abutting and supporting effect on the clamping and locking plate. After the clamping and locking plate becomes loose, the close-fitting and locking effect with the stepless locking wheel is lost. The rotating shaft, the tooling plate, and the clamping tooling assembly can then adjust the angle. During this process, the clamping tooling assembly can be locked and positioned at any angle, possessing the advantage of stepless adjustment. By performing stepless adjustment through the locking plate member, any-angle positioning of the tooling plate can be satisfied, improving the angle adjustment effect of the clamping tooling.

[0014] 2. By providing a pushing mechanism in the present utility model, the clamping and locking plate can be pushed to rotate, preventing the clamping and locking plate from failing to closely fit with the stepless locking wheel, which may lead to the inability of the stepless locking wheel to lock the angles of the tooling plate and the clamping tooling assembly, thus improving the positioning effect of the clamping tooling assembly.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 to 4As shown in the figure, a clamping tool for welding a pressure vessel assembly provided by the present utility model includes a U-shaped plate 1.

On the surface of the rotating shaft 4, a stepless locking wheel 5 is fixedly connected. On the outside of the stepless locking wheel 5, there is a clamping locking plate 6. The clamping locking plate 6 is movably connected to the outside of the U-shaped plate 1 through a hinge. At the bottom inside the clamping locking plate 6, a pushing mechanism 7 is provided.

[0022] Reference Figure 4 , the pushing mechanism 7 includes a mounting frame 71. The mounting frame 71 is fixedly connected to the bottom inside the U-shaped plate 1. At the top of the mounting frame 71, a motor 72 is fixedly connected. The output end of the motor 72 penetrates to the inside of the mounting frame 71. The output end of the motor 72 is fixedly connected to a rotating plate 73. On both sides of the rotating plate 73, there are moving plates 74. On the outside of the moving plate 74, a push rod 75 is fixedly connected. The outside of the push rod 75 penetrates to the outside of the U-shaped plate 1.

[0023] As a technical optimization scheme of the present utility model, by setting the pushing mechanism 7, it can push the clamping locking plate 6 to rotate, avoiding the situation that the clamping locking plate 6 cannot fit tightly with the stepless locking wheel 5, resulting in the inability of the stepless locking wheel 5 to lock the angles of the tooling plate 2 and the clamping tooling assembly 3, and improving the positioning effect of the clamping tooling assembly 3.

[0024] Reference Figure 4 , on the front side and the rear side inside the U-shaped plate 1, sliding rods 8 are fixedly connected. The moving plates 74 are slidably connected to the surfaces of the sliding rods 8.

[0025] As a technical optimization scheme of the present utility model, by setting the sliding rods 8, it can stabilize the sliding of the moving plates 74, avoiding the shaking of the moving plates 74 during the sliding process, resulting in the loosening of the moving plates 74, and improving the sliding stability of the moving plates 74.

[0026] Reference Figure 4 , a stabilizing sleeve 9 is sleeved on the surface of the sliding rod 8. The surface of the stabilizing sleeve 9 is fixedly connected to the surface of the moving plate 74.

[0027] As a technical optimization scheme of the present utility model, by setting the stabilizing sleeve 9, it can perform secondary sliding stability on the moving plates 74, avoiding the shaking of the moving plates 74 during the sliding process, and improving the sliding stability of the moving plates 74.

[0028] Reference Figure 4 , on the surface of the sliding rod 8, a mounting block 10 is fixedly connected. On both sides of the mounting block 10, tension springs 11 are fixedly connected. The surfaces of the tension springs 11 are fixedly connected to the inside of the moving plate 74.

[0029] As a technical optimization solution of the present utility model, by arranging a tension spring 11, the moving plate 74 can be automatically reset and moved, avoiding the situation that the moving plate 74 cannot automatically return to its original position after being pushed and requiring manual reset, thus improving the convenience of use of the moving plate 74.

[0030] Reference Figure 3 , a limiting sleeve 12 is sleeved on the surface of the push rod 75, and the bottom of the limiting sleeve 12 is fixedly connected to the bottom of the inner wall of the U-shaped plate 1.

[0031] As a technical optimization solution of the present utility model, by arranging the limiting sleeve 12, the sliding of the push rod 75 can be stabilized, avoiding the shaking of the push rod 75 during the sliding movement, resulting in the loosening of the push rod 75, and improving the sliding stability of the push rod 75.

[0032] Reference Figure 4 , pulleys 13 are rotatably connected to both sides of the rotating plate 73, and the surface of the pulley 13 is in contact with the surface of the moving plate 74.

[0033] As a technical optimization solution of the present utility model, by arranging the pulleys 13, the contact between the rotating plate 73 and the moving plate 74 can be isolated, avoiding the friction between the surface of the rotating plate 73 and the surface of the moving plate 74 when the rotating plate 73 moves, resulting in the wear of the surface of the moving plate 74, and improving the installation safety of the moving plate 74.

[0034] The working principle and usage process of the present utility model: When in use, in the figure, the stepless locking wheel 5 and the clamping locking plate 6 are in a tightly fitting state, the stepless locking wheel 5 is fastened by the clamping locking plate 6, the stepless locking wheel 5 and the rotating shaft 4 are positioned, and the tooling plate 2 and the clamping tooling assembly 3 are angularly positioned. When it is necessary to adjust the angle of the clamping tooling assembly 3, the motor 72 is started, the motor 72 drives the rotating plate 73 to rotate, the rotating plate 73 is inclined, the rotating plate 73 loses the supporting effect on the moving plate 74 and the push rod 75. After the push rod 75 is loosened, the push rod 75 loses the abutting and supporting effect on the clamping locking plate 6. After the clamping locking plate 6 is loosened, the tightly fitting and locking effect with the stepless locking wheel 5 is lost, and the rotating shaft 4, the tooling plate 2 and the clamping tooling assembly 3 can be adjusted in angle. During this process, the clamping tooling assembly 3 can be locked and positioned at any angle, thus having the advantage of stepless adjustment.

[0035] In summary, for the clamping tooling for welding the pressure vessel assembly, through the combined use of the U-shaped plate 1, the tooling plate 2, the clamping tooling assembly 3, the rotating shaft 4, the stepless locking wheel 5, the clamping locking plate 6, and the pushing mechanism 7, it solves the problem that the tooling plate is positioned at an angle by the insertion fit of the limiting hole and the limiting rod. However, there are regular intervals between the limiting holes, and a stepped adjustment will be formed during the adjustment of the tooling plate. When the angle that the tooling plate needs to be adjusted is between the limiting holes, the fit between the limiting hole and the limiting rod will not be able to meet the angle positioning of the tooling plate, reducing the angle adjustment effect of the clamping tooling.
