Technical Field

[0001] The utility model belongs to a steel pipe clamp, in particular to a clamp for processing steel pipes. Background Art

[0002] A fixture is a device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a clamp. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process in the process can be called a fixture.

[0003] The Chinese patent with announcement number CN220660028U discloses a multi-steel pipe processing fixture for steel pipe production and processing, including a base plate, a movable groove is opened on the upper side of the base plate, and the base plate located inside the movable groove is internally rotatably connected with a bidirectional screw rod, one end of the bidirectional screw rod rotates through the inner wall of the base plate and extends to the outside of the base plate, and one side of the bidirectional screw rod located outside the base plate is fixedly connected to a first rotating disk.

[0004] However, the above patent has the following shortcomings:

[0005] 1. The above patent can place steel pipes of different diameters by setting two sets of side clamping plates at an angle, and can fix the placed steel pipes with a stop block. However, the above patent cannot adjust the angle of the steel pipe according to the processing requirements after the steel pipe is fixed. It is necessary to release the fixation of the steel pipe, rotate the steel pipe, and then fix it, which makes the use of the device inconvenient;

[0006] The above patent can place steel pipes of different diameters by means of two sets of side clamping plates arranged at an angle, and can fix the placed steel pipes by means of a stop block. However, when clamping the steel pipe, the above patent will cover a part of the surface of the steel pipe, which will have an adverse effect on the subsequent processing of the steel pipe.

When the rotating disk rotates, it will drive multiple arc-shaped guide grooves on its surface to rotate synchronously. When the arc-shaped guide groove rotates, it will drive the stop rod to slide in the slide groove through the guide shaft movably connected to it, and then drive the stop block to move synchronously through the stop rod;

[0016] Therefore, through the above structure, after rotating the knob, multiple blocks can be driven to move synchronously at the same time, and then after the steel pipe is sleeved on the outer periphery of multiple blocks, multiple blocks can be pressed against the inner wall of the steel pipe, so that the steel pipe is fixed by friction;

[0017] And by rotating the fixing tube by the handle, the fixing tube and the mounting shell can be abutted against each other, and then the fixing tube and the extension rod are fixed by friction force, and then the knob is locked.

[0018] Preferably, the outer circumference of the guide shaft is rotatably connected with a roller, the number of the rollers is set to be multiple, and the multiple rollers are distributed around the center of the guide shaft;

[0019] By arranging a plurality of rollers on the periphery of the guide shaft, the sliding friction between the guide shaft and the guide groove can be converted into the rotational friction of the rollers, thereby reducing the wear between the guide shaft and the guide groove, which is beneficial to increasing the service life of the device.

[0020] Preferably, the stop block is configured to be arc-shaped, a protective pad is fixedly connected to the surface of the stop block, and the protective pad is made of rubber material;

[0021] By setting the stop block to be arc-shaped and arranging a protective pad on the surface of the stop block, the release area between the stop block and the inner wall of the steel pipe can be increased through the shape of the stop block and the elastic deformation of the protective pad after the stop block contacts the inner wall of the steel pipe, thereby avoiding deformation of the steel pipe due to excessive local force. The provision of the protective pad can avoid scratching the surface of the steel pipe due to rigid contact between the stop block and the steel pipe.

[0024] 2. By setting up a fixing mechanism, multiple blocks can be adjusted synchronously by rotating the knob, so that the inner wall of the steel pipe can be squeezed by multiple blocks to fix the steel pipe. This fixing method can avoid the surface of the steel pipe being blocked by the clamp, thereby improving the application range of the device. BRIEF DESCRIPTION OF THE DRAWINGS
