Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to an automatic transmission device for a cold welding machine. Background Technology

[0002] Cold welding machines use the high heat energy generated by the instantaneous discharge of micro-electricity to melt special welding wire onto the damaged parts of the workpiece, firmly fusing it with the original substrate. Post-weld processing requires minimal grinding and polishing. Non-standard containers refer to pressure vessels that do not conform to national or industry standards, primarily used to meet specific process requirements. These devices are usually customized according to specific customer needs, thus having a wide range of applications, including petroleum, chemical, power, and food industries. Non-standard containers come in many types, each playing a unique role in industrial production. Cryogenic containers are a type of non-standard container, mainly including cryogenic pressure storage tanks and cryogenic pipelines. Currently, cold welding machines are commonly used to weld tubular products such as pressure storage tanks and pressure pipelines within non-standard containers.

[0003] In the prior art, such as the CNC hydraulic automatic cold welding machine with announcement number CN110919249A, a cold welding machine body, a positioning and clamping device, and a driving displacement device are included. The bottom of the cold welding machine body is movably inserted into the interior of the positioning and clamping device, and the driving displacement device is fixedly installed on the bottom of the positioning and clamping device. The CNC hydraulic automatic cold welding machine of this invention, by setting up a driving displacement device, uses a motor to drive two rotating shafts to rotate together, causing the sliding sleeve to move along the sliding rod direction, prompting the casters to be retracted into the storage cavity or to contact the ground. This allows the cold welding machine to slide with the assistance of the casters. After reaching the target point, the casters can be retracted, allowing the cold welding machine to switch freely between two states: placement and movement. This also avoids the need for manual handling, making the cold welding machine easy to move while improving placement efficiency.

[0004] When welding tubular products in non-standard containers, existing cold welding machines require manual rotation of the tubular products or adjustment of the machine head position during the welding process due to the characteristics of the tubular products. This is not conducive to the welding work. Furthermore, existing cold welding machines have poor adaptability to tubular products of different sizes.

[0005] Therefore, it is necessary to invent an automatic transmission device for a cold welding machine to solve the above problems. Utility Model Content

One end of multiple threaded sleeves 12 is fixedly provided with a transmission gear 16, and the transmission gear 16 meshes with the protruding teeth 15. A slide rail 25 is fixedly provided on the outer side of the transmission plate 14, and a slider 26 is fixedly provided on the outer side of the support base 2. Both the slide rail 25 and the slider 26 are designed with an "L" shape. A screw hole is opened on the outer side of the slide rail 25, and a locking bolt 23 is provided in the screw hole through the thread. One end of the locking bolt 23 is in contact with the outer wall of the support base 2. The locking bolt 23 is used to limit the position of the transmission plate 14. The slide rail 25 and the slider 26 are used to prevent the transmission plate 14 from disengaging. The inner sidewall of the support base 2 is provided with slots 17 at both ends, and the arc-shaped base 4 is provided with plugs 18 that are adapted to the slots 17 at both ends. The plugs 18 cooperate with the slots 17 to realize the connection between the arc-shaped base 4 and the support base 2. The top of the arc-shaped seat 4 is provided with a first sliding hole 19. The first sliding rod 20 is slidably provided inside the first sliding hole 19 and is fixedly provided on the upper surface of the movable seat 5.

A welding head 24 is provided above the frame 1, and the welding head 24 is located between two support bases 2. The welding head 24 adopts the corresponding structure in the prior art.

[0022] Working principle of this utility model: When in use, the arc-shaped seat 4 and the support seat 2 are separated. The tubular product to be welded can be placed inside the support seat 2. By rotating the locking bolt 23, the locking bolt 23 is separated from the support seat 2. At this time, the limit of the transmission plate 14 is released. Rotating the transmission plate 14, the transmission plate 14 drives the transmission gear 16 to rotate through the convex tooth 15. The transmission gear 16 drives the threaded sleeve 12 to rotate. During the rotation, the threaded sleeve 12 drives the adjusting screw 13 to move vertically through the thread. The adjusting screw 13 drives the support wheel 3 to move, so as to realize the synchronous adjustment of the position of multiple support wheels 3. The tubular product to be welded is placed in multiple... Between the support wheels 3, until multiple support wheels 3 simultaneously adhere to the outer wall of the tubular product, the clamping and positioning of the tubular product can be completed. Then tighten the locking bolt 23, and insert the arc-shaped seat 4 from the side into the top of the support seat 2, so that the insert blocks 18 at both ends of the arc-shaped seat 4 are respectively inserted into the slots 17 at both ends of the support seat 2. At this time, the support seat 2 and the arc-shaped seat 4 form a circular structure. By rotating the positioning screw 10, the positioning screw 10 cooperates with the positioning screw hole 11, so that the movable seat 5 drives the rubber roller 6 to move downward. Rotate the positioning screw 10 until the rubber roller 6 presses against the surface of the tubular product, and the clamping and fixing of the tubular product can be completed. When splicing and welding two tubular products, the two tubular products are clamped and positioned by two sets of support seats 2, so that the two tubular products are connected to each other and the connection point coincides with the welding head 24. The welding head 24 can then be used to weld the connection point of the tubular products. During the welding process, two drive motors 7 synchronously drive two sets of rubber rollers 6 to rotate, and the two sets of rubber rollers 6 synchronously drive the two tubular products to rotate, so as to facilitate the welding of the splicing point of the tubular products. When repairing and welding the outer surface of a single tubular product, adjust the position of the tubular product so that its welding area coincides with the welding head 24 to facilitate the repair and welding of the tubular product. It should be noted that this embodiment only provides the clamping and transmission structure for the welding process of tubular products in non-standard containers. For the welding head 24 and other structures in the welding process, the corresponding structures in the prior art are adopted. The welding head 24 can be used with power components such as cylinders to adjust the position and height of the welding head 24. At the same time, when welding tubular products in this embodiment, after the tubular products are spliced, they can be reinforced by electric welding at their joints to improve stability. When processing tubular products that are long or heavy, multiple sets of support seats 2 can be added to ensure stability. It should be further explained that the drive motor 7 in this embodiment is a motor with a self-locking function in the prior art. It is equipped with a controller and power supply. When it is not working, it has a self-locking effect to achieve the positioning of the tubular product.
