[0027] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example 1:

[0029] like Figures 1 to 5 As shown in the figure, this utility model provides a pipe clamp for welding pipes; the clamp includes: a clamping assembly 100, a lifting assembly 400, and a translation assembly 300;

[0030] The clamping assembly 100 is used to clamp the second pipe 600; this device is used to assist in welding the second pipe 600 onto the first pipe 100; the clamping assembly 100 is slidably connected to the lifting assembly 400; the translation assembly 300 is fixedly connected to the lifting assembly 400.

[0031] The clamping assembly 100 includes a support plate 102, on which a first hinge block 104 is fixedly mounted, and a cylinder 103 is fixedly mounted on the side of the first hinge block 104. The first hinge block 104 has several connecting grooves, which are hinged to a first connecting rod 107. The top end of the piston rod of the cylinder 103 is fixedly connected to a second hinge block 105. The second hinge block 105 has a connecting groove, which is hinged to a second connecting rod 106. The other end of the first connecting rod 107 is hinged to the second connecting rod 106, and a pin at the hinge point is fixedly connected to a clamping block 108.

[0032] The clamping assembly 100, through the telescopic piston rod of the cylinder 103, drives the second hinge block 105 closer to the cylinder 103. The second hinge block 105 pulls the second connecting rod 106 towards the cylinder 103, causing the other end of the second connecting rod 106 to move away from the piston rod, pulling the clamping block 107 away from the piston rod; the second connecting rod 106 pulls the first connecting rod 107 away from the piston rod and closer to the cylinder 103; thus achieving the effect of the clamping block 108 moving outward, and the clamping assembly 100 gripping the second pipe 600.

[0033] The translation component 300 includes a limiting block 301, which is fixedly connected to a first slide rail 303; a slider 302 is slidably disposed on the first slide rail 303; and the slider 302 is fixedly connected to a lifting component 400.

[0034] The translation component 300 moves the slider 302, causing the lifting component 400 on the slider 302 to move; thus achieving the translation effect of the lifting component 400, which in turn drives the clamping component 100 on the lifting component 400 to move left and right, thereby clamping the second welding pipe 600.

[0035] The lifting assembly 400 includes a support base 401, with a U-shaped box 402 fixedly connected to its side. A second slide rail 403 is provided on the protrusion of the U-shaped box 402, and a lead screw 404 is rotatably mounted inside the U-shaped box 402. A limiting device 407 is fixedly mounted above the U-shaped box 402, and a bearing is provided inside the limiting device 407.

[0036] The lead screw 404 passes through the U-shaped housing 402 and is fixedly connected to the handle 408, and the lead screw 404 is fixedly connected to the bearing in the limiting device 407; the lead screw 404 and the nut of the guide device 405 are threadedly fixed; the guide device 405 and the slide rail of the U-shaped housing 402 are slidably fixed; and the guide device 405 is provided with a lifting device fixing device 406;

[0037] The lifting component 400 rotates the screw 404 by rotating the handle 408, causing the nut on the guide device 405 to move along the axis of the screw 404; thus achieving the effect of the guide device 405 moving up and down, thereby achieving the effect of the clamping component 100 moving up and down.

[0038] Example 2:

[0039] like Figures 1 to 5 As shown, the difference from Embodiment 1 is that, in order to further increase the stability of the welding, a support assembly 200 is provided below the second welding pipe 600.

[0040] The lifting assembly 200 includes a lifting base 201, on which a first hinge plate 202 is fixedly mounted; the first hinge plate 202 has a hinge hole, through which a first connecting rod 203 and a second connecting rod 204 are hinged to a pin; and the other end of the first connecting rod 203 is hinged to a first connecting block 205; the other end of the second connecting rod 204 is hinged to a second connecting block 206.

[0041] The first connecting rod 203 is also hinged to a third connecting rod 207; the second connecting rod 204 is also hinged to a fourth connecting rod 208, and the third connecting rod 207 and the fourth connecting rod 208 are hinged together; the hinge position of the third connecting rod 207 and the fourth connecting rod 208 is located on the second hinge plate 209; an arc-shaped support plate 212 is fixedly provided on the second hinge plate 209;

[0042] The lifting assembly 200 also includes a bidirectional lead screw 210, which is threadedly connected to the second connecting block 206 and the first connecting block 205. A handle 211 is fixedly connected to one end of the bidirectional lead screw 210 near the second connecting block 206. A sleeve 214 is fixedly provided on the side of the second connecting block 206 near the handle 211. A limit bolt 213 is threaded on the sleeve 214. The bidirectional lead screw 210 passes through the sleeve 214. Tightening the limit bolt 213 limits the bidirectional lead screw and prevents accidental contact.

[0043] The lifting assembly 200, by rotating the handle 211, drives the lead screw 210 to rotate, causing the first connecting block 205 and the second connecting block 206 to move towards each other; driving the movement of multiple hinge plates; thereby driving the arc-shaped support plate 212 to move upward, achieving the effect of the lifting assembly 400 moving upward.

[0044] Working principle:

[0045] By moving the slider 302, the lifting component 400 on the slider 302 moves, achieving the effect of translation of the lifting component 400, thereby driving the clamping component 100 on the lifting component 400 to move left and right. By rotating the handle 211, the lead screw 210 is rotated, causing the first connecting block 205 and the second connecting block 206 to move towards each other; driving the movement of multiple hinge plates; thereby driving the arc-shaped support plate 212 to move upward, achieving the effect of upward movement of the lifting component 400, thereby driving the clamping component 100 on the lifting component 400 to move up and down, placing the clamping component 100 inside the second pipe 600, via the cylinder 1. The telescopic piston rod of 03 drives the second hinge block 105 to approach the cylinder 103. The second hinge block 105 pulls the second connecting rod 106 to move closer to the cylinder 103, so that the other end of the second connecting rod 106 moves away from the piston rod, pulling the clamping block 107 away from the piston rod. The second connecting rod 106 pulls the first connecting rod 107 away from the piston rod and closer to the cylinder 103. This achieves the effect of the clamping block 108 moving outward, so that the clamping assembly 100 can grip the second pipe 600. This facilitates the clamping operation of second pipes 600 with different inner diameters, thereby facilitating the welding operation of the second pipe 600 on the first pipe 500.
