Description

Technical Field

[0001] The utility model relates to a clamp, in particular to a stainless steel pipe processing clamp. Background Art

[0002] When installing equipment, the pipe openings of some equipment are at a large height from the ground. Since the equipment is usually installed first and then the pipes are installed, the pipes installed later need to be welded off the ground. Currently, a crane is generally used to lift both ends of the pipes, and then they are manually held together for welding. This method is firstly inefficient, and the pipes need to be tied with hinges and then untied after welding. Secondly, the manual docking method is prone to swinging, and the concentricity is prone to deviation, which needs to be constantly corrected during the welding process. Utility Model Content

DETAILED DESCRIPTION

[0016] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] As shown in the figure:

[0018] A stainless steel pipe processing fixture comprises a movable base 1, on which a horizontal slide 3 is mounted via a bracket, on which two pipe clamps 5 which can slide along are mounted, and the pipe clamps 5 have an adjustment structure, on which a clamping part A5555, a clamping part B5656 and a clamping part C5757 are respectively mounted, and the clamping part A5555, the clamping part B5656 and the clamping part C5757 are arranged in an isosceles triangle and can be opened or closed under the drive of the adjustment structure, and maintain an isosceles triangle distribution state during the opening and closing process.

[0019] The utility model is mainly used for the installation and welding of stainless steel pipe fittings. It is arranged as a whole on a movable base 1, which is convenient for transfer on site. The pipe clamp 5 can be moved along the slide 3, so as to adjust the clamping position to cope with pipe fittings of different lengths. The clamping part A5555, the clamping part B5656 and the clamping part C5757 of the pipe clamp 5 are arranged in an isosceles triangle, and can be opened or closed under the drive of the adjustment structure, so as to achieve stable clamping of pipe fittings of different diameters. Considering the simplicity of structural design and the ease of operation, the clamping part A5555 and the clamping part B5656 are located at the base of the isosceles triangle and are all in the same horizontal plane, and the clamping part C5757 is located at the vertex.

[0020] Specifically, the pipe clamp 5 includes a rod seat 51 and an arc-shaped clamping arm 52 hinged on both sides of the rod seat 51, the bottom of the arc-shaped clamping arm 52 is bent inward, and the clamping part A5555 and the clamping part B5656 are respectively fixed at the ends of the arc-shaped clamping arm 52, and a slide groove 521 is opened in the middle of the arc-shaped clamping arm 52 along its length direction; an adjusting screw 53 is installed in the middle of the rod seat 51, and a pressure head 54 is installed at the bottom end of the adjusting screw 53, and a clamping part C5757 is installed at the bottom of the pressure head 54. The pressure head 54 is symmetrical with the adjusting screw 53 as the central axis, and a group of connecting arms 541 that clamp the arc-shaped clamping arm 52 in the middle are installed on the end faces on both sides, and a sliding column 542542 passing through the slide groove 521 is installed between the ends of the same group of connecting arms 541.

[0021] When it is necessary to close the pipe clamp 5 to clamp the pipe fitting, twist the adjusting screw 53 to push the pressure head 54 downward. During the downward movement of the pressure head 54, the sliding column 542542 will slide along the sliding groove 521, thereby pulling the arc-shaped clamping arm 52 to close. During this process, the clamping part A5555, the clamping part B5656 and the clamping part C5757 can be gradually closed to complete the clamping and fixation of the pipe fitting.

[0022] On the basis of the above structural design, sliders 511 are integrally extended from both sides of the rod seat 51, a through slot 31 is provided through the center of the slide 3 along the length direction, and slide rails 32 are symmetrically processed on both side walls of the through slot 31. The sliders 511 of the pipe clamp 5 are respectively embedded in the slide rails 32, so that the pipe clamp 5 slides along the through slot 31, so that the pipe clamp 5 can slide smoothly while facilitating the operation of the adjusting screw 53.

[0023] As an optimized design, the slide 3 is split, and the two ends are connected as one through a rectangular buckle 4 with bolts, which is convenient for separate processing. The integrated design slide rail 32 is inconvenient to process.

[0024] As an optimized design scheme, the bracket includes multiple motor screw lifters 2 and extension plates 21. The extension plates 21 are vertically welded on both sides of the slide 3. The top of the motor screw lifter 2 is welded to the end of the extension plate 21. The extension plate 21 can leave more operating space in the middle, and the motor screw lifter 2 is used to adjust the height of the slide 3 to cope with different installation heights.

[0025] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
