[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1:

[0023] See also Figure 1-3 In this embodiment, a positioning tool for pressure vessel processing includes a support base 1. Two support columns 11 for support are provided on the top of the support base 1. The opposite sides of the two support columns 11 are fixedly connected to a connecting platform 12. The bottom of the connecting platform 12 is provided with a connecting gear 15 for connection. The two connecting gears 15 are both transmission-connected to two clamping assemblies 2; an electric push rod 13 for transmission is provided on the top of the connecting platform 12, and the push rod end of the electric push rod 13 is fixedly connected to a transmission block 14, and the transmission block 14 is fixedly connected to a clamping assembly 2;

[0024] The clamping assembly 2 includes a connecting column 21, the top of the connecting column 21 is fixedly connected to a mounting plate 22, the top of the mounting plate 22 is fixedly connected to a guide platform 23 for guiding, two guide columns 18 are provided at the bottom of the support column 11, and the two guide columns 18 are both slidably connected to the guide platform 23, and the opposite sides of the two mounting plates 22 are fixedly connected to a gear rod 24 for linkage, and the two gear rods 24 are both engaged with the connecting gear 15; the bottom of the connecting column 21 is also provided with a clamping jaw 25 for fixing the pressure vessel, and a plurality of adjusting wheels 26 are provided in the two clamping jaws 25.

[0025] As a preferred technical solution in this embodiment: during the processing of the pressure vessel, the worker can place the pressure vessel between the two clamping assemblies 2, and then control the electric push rod 13 to drive the transmission block 14 to produce a displacement effect. During the displacement of the transmission block 14, the connecting column 21 can be driven to cause the gear rod 24 to produce a displacement effect. During the displacement of the gear rod 24, the connecting gear 15 can be driven to rotate. During the rotation of the connecting gear 15, the other gear rod 24 can be driven to produce a displacement effect, thereby achieving the effect of driving the two connecting columns 21 to produce relative or reverse displacement. In actual use, when the worker When the operator needs to position the pressure vessel, he can control the electric push rod 13 to drive the transmission block 14 to move close to the connecting gear 15. At this time, under the action of the connecting gear 15, the momentum clamp 25 can produce a relative displacement effect. When the clamp 25 drives the adjusting wheel 26 to move until multiple adjusting wheels 26 are in fit with the pressure vessel, the pressure vessel is fixed in the horizontal and vertical directions. At the same time, since the adjusting wheel 26 and the clamp 25 are rotatably connected, when welding the pressure vessel, the operator can achieve the effect of multi-angle welding of the pressure vessel by controlling the rotation of the pressure vessel without adjusting the posture.

[0026] The technical effects brought about by the above-mentioned embodiment are as follows: by providing the connecting gear 15 and the gear rod 24, it is possible to effectively achieve the centering clamping effect when fixing the pressure vessel, thereby ensuring the welding accuracy of the pressure vessel; by providing multiple adjustment wheels 26 in the clamping jaw 25, it is possible to control the rotation of the pressure vessel while positioning the pressure vessel, thereby facilitating the staff to adjust the welding angle and avoiding the use of complex postures or tools to achieve the welding effect during the welding process.

[0027] Example 2:

[0028] See also Figure 1-3 In order to facilitate the workers to adjust the angle of the pressure vessel during the welding process, the two clamping jaws 25 in this embodiment are both arc-shaped and have mounting grooves on the opposite sides of the two clamping jaws 25. Multiple adjustment wheels 26 are rotatably connected to the mounting grooves. The bottom of the connecting platform 12 is fixedly connected to two mounting seats 19. The bottom of the two mounting seats 19 is rotatably connected to two guide wheels 191 for guiding the gear rod 24. The two guide wheels 191 are located on both sides of the connecting gear 15, and the two gear rods 24 are respectively located between the two guide wheels 191 and the connecting gear 15. A transmission motor 16 is provided at the bottom of the support base 1. The output shaft of the transmission motor 16 passes through the upper surface of the support base 1 and is fixedly connected to the adjustment platform 17. The adjustment platform 17 is located directly below the connecting gear 15.

[0029] As a preferred technical solution in this embodiment: during the welding of the pressure vessel, the worker can place the pressure vessel on the adjustment platform 17, and then control the electric push rod 13 to drive the clamping assembly 2 to achieve the effect of fixing the pressure vessel. At this time, the pressure vessel is just located at the center of the adjustment platform 17. When it is necessary to adjust the welding angle of the pressure vessel, the worker can control the transmission motor 16 so that its output shaft drives the adjustment platform 17 to rotate, thereby achieving the effect of controlling the rotation of the pressure vessel. This method can effectively facilitate the worker to adjust the pressure vessel.

[0030] Furthermore, in order to increase the friction between the adjusting platform 17 and the pressure vessel, the staff can add an anti-slip pad on the top of the adjusting platform 17. If the material of the pressure vessel is an iron-containing alloy material, an electromagnet can be added to the adjusting platform 17 to ensure that it can control the rotation of the pressure vessel during the welding process.

[0031] The technical effects brought about by the above embodiment are: by providing a transmission motor 16 and an adjustment platform 17, it is possible to effectively facilitate the staff to adjust the pressure vessel during the welding process during use, avoiding the need for manual adjustment and effectively reducing the workload of the staff.

[0032] The working principle of the above embodiment is:

[0033] 1. During the processing of the pressure vessel, the staff can place the pressure vessel between the two clamping assemblies 2, and then control the electric push rod 13 to drive the transmission block 14 to produce a displacement effect. During the displacement of the transmission block 14, the connecting column 21 can be driven to cause the gear rod 24 to produce a displacement effect. During the displacement of the gear rod 24, the connecting gear 15 can be driven to rotate. During the rotation of the connecting gear 15, the other gear rod 24 can be driven to produce a displacement effect, thereby achieving the effect of driving the two connecting columns 21 to produce relative or reverse displacement. In actual use, when the staff needs to adjust the pressure vessel After the device is positioned, the transmission block 14 can be driven to move close to the connecting gear 15 by controlling the electric push rod 13. At this time, under the action of the connecting gear 15, the momentum clamp 25 can be driven to produce a relative displacement effect. When the clamp 25 drives the adjusting wheel 26 to move until multiple adjusting wheels 26 are in contact with the pressure vessel, the pressure vessel can be fixed in the horizontal and vertical directions. At the same time, since the adjusting wheel 26 and the clamp 25 are rotatably connected, when welding the pressure vessel, the staff can achieve the effect of multi-angle welding of the pressure vessel by controlling the rotation of the pressure vessel without adjusting their posture.

[0034] 2. During the welding process of the pressure vessel, the staff can place the pressure vessel on the adjustment table 17, and then control the electric push rod 13 to drive the clamping assembly 2 to achieve the effect of fixing the pressure vessel. At this time, the pressure vessel is just located at the center of the adjustment table 17. When the welding angle of the pressure vessel needs to be adjusted, the staff can control the transmission motor 16 so that its output shaft drives the adjustment table 17 to rotate, thereby achieving the effect of controlling the rotation of the pressure vessel. This method can effectively facilitate the staff to adjust the pressure vessel.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
