The drum ring, part of the axial-flow drum body, requires a coiling process before assembly. This involves using a coiling machine to roll the sheet material into a cylindrical shape before welding. The existing GV drum coiling fixture has a simple structure and lacks adequate support for the drum ring, resulting in poor quality during welding. Furthermore, manual removal of the drum ring from the fixture after welding is required, which is time-consuming and labor-intensive. Summary of the Invention

DETAILED DESCRIPTION

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0029] See also Figures 1-6 A roller welding device includes a frame 101 and an intermediate frame 201. The intermediate frame 201 is slidably installed on the frame 101. An upper frame 301 is hingedly provided on the intermediate frame 201. The upper frame 301 is provided with at least two groups of clamping units. The clamping units include relatively arranged clamping mechanisms 4, and the clamping mechanisms 4 jointly clamp the roller ring.

[0030] See also Figure 6The clamping mechanism 4 includes a clamping plate 401 and a clamping cylinder 402. The clamping plate 401 is hingedly mounted on the upper frame 301. The clamping plate 401 is arc-shaped. The two clamping plates 401 of the clamping mechanism 4 are arranged opposite each other and together form a semicircular clamping surface for clamping the drum ring. The cylinder body of the clamping cylinder 402 is hingedly mounted on the upper frame 301, and the end of the piston rod of the clamping cylinder 402 is hingedly connected to the middle of the clamping plate 401. To provide a stable clamping effect on the drum ring, the clamping unit is provided in three groups.

[0031] A mounting base 303 is provided on the upper frame 301, and the end of the clamping plate 401 is hingedly installed in the mounting base 303. The mounting base 301 includes a seat plate and two hinged plates for installing the clamping plate 401. The clamping plate 401 is hingedly installed between the two hinged plates. In addition to providing a hinged mounting point for the clamping plate 401, the two hinged plates also provide a limiting function on both sides to prevent the clamping plate 401 from offsetting during rotation.

[0032] One end of the upper frame 301 is hingedly mounted on the middle frame 201 , and support columns 302 are provided on both sides of the end of the upper frame 301 hingedly mounted on the middle frame 201 .

[0033] The intermediate frame 201 is provided with a jacking power mechanism 5 , the power output end of the jacking power mechanism 5 is transmission-connected to the upper frame 301 , and the jacking power mechanism 5 is used to drive the upper frame 301 to rotate around the hinge point with the intermediate frame 201 .

[0034] The lifting power mechanism 5 is a lifting cylinder, the cylinder body of which is hingedly mounted on the intermediate frame 201, and the end of the piston rod of the lifting cylinder is hingedly connected to the upper frame 301. The piston rod of the lifting cylinder extends, driving the upper frame 301 to rotate around the hinge point with the intermediate frame 201. When the upper frame 301 rotates to a position perpendicular to the intermediate frame 201, the support column 302 supports the intermediate frame 201, providing support for the upper frame 301 and the roller clamped on the upper frame 301. On the one hand, it protects the lifting cylinder and prevents the piston rod of the lifting cylinder from being damaged due to continuous force. On the other hand, it provides stable support for the upper frame 301 and prevents it from shaking.

[0035] One end of the intermediate frame 201 is provided with a frame hinge seat, and the other end of the intermediate frame 201 is provided with an intermediate vertical pipe 203 (see Figure 5 ), the upper frame 301 is hingedly mounted on the frame body hinge seat. When the upper frame 301 is horizontal, the top surface of the intermediate vertical pipe 203 presses against the bottom surface of the upper frame 301. During welding, the piston rod of the jacking cylinder retracts and resets, and the upper frame 301 is horizontal. The intermediate vertical pipe 203 can provide stable support for the upper frame 301.

[0036] Limiting plates 105 are provided at both ends of the frame 101 , and limiting pins 205 are provided at both ends of the intermediate frame 201 corresponding to the limiting plates 105 .

[0037] Guide plates 204 are respectively provided at both ends of the intermediate frame 201 corresponding to the limiting vertical plates 105 . The limiting pins 205 are detachably inserted into the guide plates 204 . The bottom surface of the guide plates 204 is higher than the top surface of the limiting vertical plates 105 .

[0038] The frame 101 is provided with a slide rail 102 , and the intermediate frame 201 is provided with a slider 202 , which is slidably mounted on the slide rail 102 .

[0039] It also includes a translational power mechanism, which provides power for the translation of the intermediate frame 201 on the slide rail 102. The present invention does not limit the specific structure of the translational power mechanism. As a preferred embodiment of the present invention, the translational power mechanism is a translation cylinder.

[0040] In order to facilitate the movement of the equipment, fixed wheels 104 and universal wheels 103 are respectively provided at both ends of the bottom of the frame 101.

[0041] The use process of this utility model is as follows:

[0042] In the initial state, the piston rod of the lifting cylinder is retracted, the upper shelf 301 is in a horizontal state, and the upper end surfaces of the two middle risers 203 of the middle shelf 201 touch the bottom surface of the upper shelf 301;

[0043] Pull out the limit pin 205 at one end of the intermediate frame 201, and the piston rod of the translation cylinder extends to push the intermediate frame 201 along the slide rail 102 until the intermediate frame 201 moves to the end of the frame 101. Here, the end of the frame 101 is placed close to the rolling machine, and the limit plate 105 blocks the intermediate frame 201;

[0044] Then, the limiting pin 205 on the intermediate frame 201 is inserted into the guide plate 204, and the end of the limiting pin 205 abuts against the outer side of the limiting vertical plate, thereby providing a limiting effect on the intermediate frame 201 through the limiting pin 205;

[0045] The piston rod of the clamping cylinder 402 contracts, driving the multiple clamping plates 401 on the upper frame 301 to rotate around the installation hinge point. The clamping plates 401 are opened, and the roller ring removed from the roller rolling machine is placed on the upper frame 301 and between the clamping plates 401 on both sides. The piston rod of the clamping cylinder 402 extends, driving the multiple clamping plates 401 on the upper frame 301 to rotate around the installation hinge point. The semicircular clamping surface formed by the two opposing clamping plates 401 clamps the roller ring, and then the butt joint of the roller ring is welded. Specifically, the three welding points at both ends and the middle of the butt joint are welded.

[0046] After welding is completed, the limit pin 205 is pulled out, and the piston rod of the translation cylinder contracts to push the intermediate frame 201 to move along the slide rail 102 until the intermediate frame 201 moves to the other end of the frame 101. The limit pin 205 inserted into the other end of the intermediate frame 201 provides a limit for the intermediate frame 201, and the piston rod of the lifting cylinder extends, lifting the upper frame 301 to rotate around the hinge point between it and the intermediate frame 201 until the two support columns of the upper frame 301 hit the top surface of the intermediate frame 201 , so that the upper frame 301 and the roller ring thereon are in a state perpendicular to the ground, the piston rod of the clamping cylinder 402 contracts, driving the multiple clamping plates 401 on the upper frame 301 to rotate around the installation hinge point, opening the clamping plates 401, and the roller ring that loses the clamping of the clamping plates 401 falls to the ground under the action of gravity, and falls into the frame body of the frame 101. Under the action of the frame 101, the roller ring will not flip over at will, making it easier for workers to take the parts. At this point, the welding of the roller ring is completed.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
