Abstract
Description
Technical Field
[0001] This utility model belongs to the field of flange processing technology, and specifically relates to a flange welding clamping and positioning device. Background Technology
[0002] A flange welding clamping and positioning device is a mechanical device used to precisely fix a flange to a pipe or other connecting component during the welding process. Its core function is to ensure that the position, angle, and concentricity between the flange and the mating component meet the design requirements, thereby guaranteeing the sealing performance, strength, and geometric accuracy of the welded joint. During operation, after the flange is fixed to the device, the operator can manually adjust its horizontal, vertical, and rotational angles to ensure that the welding surface is completely flush with the mating component, avoiding welding defects caused by misalignment. However, existing flange welding clamping and positioning devices still have shortcomings. Most devices are only suitable for flanges of specific sizes or types. When dealing with flanges of different specifications, frequent changes of clamps or adjustments to the structure are required, significantly increasing preparation time and labor costs. Therefore, a new structure is proposed to solve these problems. Utility Model Content

[0010] In a preferred embodiment, a support frame is welded above the movable base, and an electric push rod is installed on the top of the support frame. The bottom output end of the electric push rod is fixed to the top of the upper clamping member by a push rod.
[0011] In a preferred embodiment, the clamping assembly is provided with a stabilizing support on the left side. The stabilizing support includes a stabilizing ring for stabilizing the flange pipe.

[0014] In a preferred embodiment, the inner radius of the extension cylinder matches the radius of the left side of the flange.

In actual use, the flange pipe can be rotated inside the stabilizing ring and clamping assembly one respectively by the synchronous rolling of drive roller one and drive roller two. At the same time, the flange and the left side of the flange rotate inside clamping assembly two. Then, the rotation angle of the flange and flange pipe can be controlled by controlling the rolling radius of drive roller one and drive roller two. Therefore, the welding angle of the flange can be flexibly adjusted. After adjustment, the top left side of the flange can be pressed down by the locking plate. Therefore, the flange and flange pipe can be stably clamped by friction. Attached Figure Description

[0027] 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.
[0028] Please see Figures 1-4 As the first embodiment of this utility model: a flange welding clamping and positioning device, including: clamping component 200 and clamping component 400, clamping component 200 is installed on the right side of the upper surface of the working plate 100, and clamping component 200 includes a lower clamping member 220 and an upper clamping member 230 for clamping flange pipe.
[0029] A support base 110 is provided on the left side of the work plate 100. A clamping assembly 400 for clamping the flange is installed inside the support base 110. The clamping assembly 400 includes a locking plate 430 for locking the flange.
[0030] A moving groove 101 is horizontally opened on the right side of the upper surface of the work plate 100. An adjusting screw 120 is installed below the moving groove 101. A stepper motor is installed on the right side of the work plate 100.
[0031] The left output end of the stepper motor is connected to the right side of the adjusting screw 120 via a coupling. A movable base 210 is provided below the lower clamp 220. A mating hole is provided on the right side of the movable base 210. The mating hole is sleeved on the outside of the adjusting screw 120, and the specifications of the mating hole match those of the adjusting screw 120.
[0032] The lower clamp 220 has a semi-circular plate structure. An active roller 221 is installed on the lower inner side of the lower clamp 220. The active roller 221 is connected to the drive motor 1 installed inside the movable base 210 through a coupling 2.
[0033] The lower clamp 220 and the upper clamp 230 have the same specifications and are mirror images of each other. The upper clamp 230 and the lower clamp 220 together form a ring structure. A driven roller 231 is installed on the upper left and right sides of the inner side of the upper clamp 230.
[0034] A support frame is welded on top of the movable base 210. An electric push rod is installed on the top of the support frame. The bottom output end of the electric push rod is fixed to the top of the upper clamp 230 through a push rod.
[0035] In practical use, starting the stepper motor drives the adjusting screw 120 to rotate clockwise inside the moving groove 101 (the stepper motor is existing technology, and its model can be selected according to the available models on the market, which will not be elaborated further). This allows the clamping assembly 200 to move uniformly to the left along the moving groove 101 through the threaded connection between the adjusting screw 120 and the mating hole. Similarly, rotating the adjusting screw 120 counterclockwise moves the clamping assembly 200 to the right along the moving groove 101. Therefore, the distance between the clamping assembly 200 and the clamping assembly 400 can be flexibly adjusted, enabling the clamping of flanges and flanged pipes of different lengths, greatly improving clamping flexibility.
[0036] Please see Figures 1-4 As a second embodiment of the present invention: based on the description in the above embodiments, further, a stabilizing support 300 is provided on the left side of the clamping assembly 200. The stabilizing support 300 includes a stabilizing ring 310 for stabilizing the flange pipe. The stabilizing ring 310 has a semi-circular structure, and an active roller 311 is installed on the lower inner side of the stabilizing ring 310.
[0037] The second active roller 311 is connected to the second drive motor installed inside the stabilizing support 300 via a coupling 3. Two sets of driven rollers 231 are symmetrically installed above the inner side of the stabilizing ring 310, and the centers of the stabilizing support 300, the first clamping assembly 200 and the second clamping assembly 400 are on the same horizontal line.
[0038] The clamping assembly 400 also includes a mating plate 410 and an extension cylinder 420. The extension cylinder 420 is located behind the mating plate 410. A mating groove matching the radius length of the flange is opened on the right side of the mating plate 410.
[0039] The inner radius of the extension cylinder 420 matches the radius of the left side of the flange. A telescopic opening 421 is provided at the top of the extension cylinder 420, and a locking plate 430 is provided below the telescopic opening 421. Four sets of driven rollers 231 are symmetrically installed on the rear side inside the extension cylinder 420. The area enclosed by the four sets of driven rollers 231 inside the clamping assembly 2 400 is designated as region one. The area enclosed by the active roller 2 311 inside the stabilizing support 300 and the two sets of driven rollers 231 is designated as region two. The area enclosed by the active roller 1 221 inside the clamping assembly 1 200 and the two sets of driven rollers 231 is designated as region three. The centers of regions one, two, and three are on the same horizontal line, and the radii of the inscribed circles of regions one, two, and three are all the same.
[0040] The top of the extension tube 420 extends backward to form a support plate. An electric push rod 2 is installed on the top of the support plate. The bottom output end of the electric push rod 2 passes through the telescopic port 421 through a push rod 2 and is fixed to the top of the locking plate 430. The locking plate 430 is a semi-circular plate structure and is made of flexible rubber.
[0041] In actual use, firstly, the clamping assembly 200 can be moved to the right by rotating the lead screw 120 counterclockwise, leaving space for the flange and flange pipe installation. Then, the flange pipe is placed inside the stabilizing component and clamped inside the driving roller 311 and a pair of driven rollers 231. Then, the flange on the left side of the flange pipe is placed to the left inside the mating groove on the right side of the mating plate 410, with the left side of the flange not in contact with the inside of the mating groove. The left side of the flange is placed inside the extension cylinder 420. When the locking plate 430 is driven upward by the electric push rod 2, its upper surface is made to fit with the lower surface of the telescopic port 421. Then, the adjusting screw 120 is rotated clockwise to drive the clamping assembly 200 to move to the left. At this time, the upper clamp 230 and the lower clamp 220 are separated. When the right side of the flange pipe is above the driving roller 221, the electric push rod 1 is started to drive the clamping assembly downward and close to the lower clamp 220, clamping the right side of the flange pipe inside the driving roller 221 and the two sets of driven rollers 231.
[0042] After the flange and flange pipe are clamped, the drive motor 1, which drives the first drive roller 221, and the drive motor 2, which drives the second drive roller 311, can be started simultaneously (drive motor 1 and drive motor 2 are synchronous mechanisms, and both are existing technologies; their internal structures and working principles will not be described in detail here). The drive rollers 221 and 311 rotate in the same direction. Since the specifications of drive rollers 221 and 311 are identical, their surfaces rub against the surface of the flange pipe, causing the flange pipe to rotate and change the welding angle. When the flange pipe rotates, the inner front side of the extension cylinder 420... The four sets of driven rollers 231 rotate with the movement, and a pair of driven rollers 231 on the inner side of the stabilizer rotate with the movement. At the same time, a pair of driven rollers 231 on the inner side of the clamping assembly 2 400 rotate with the movement. Therefore, the rotation of the flange pipe can be made more stable. After the rotation is completed, the rotation of the first drive roller 221 and the second drive roller 311 is stopped, and the second electric push rod is started to drive the locking plate 430 downward and make its arc-shaped lower surface tightly fit with the outer left side of the flange. Then the position of the flange and the flange pipe is locked. Therefore, the final effect is that the welding angle can be flexibly adjusted, and the flange and the flange pipe can be positioned by the locking plate 430.
[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
