Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices, in particular to an auxiliary device used for processing a reducing pipe joint. Background Art

[0002] In the engineering fields of petroleum, chemical industry, food, medical treatment, etc., a large number of reducer pipe joints are used. The existing reducer pipe joints mainly include large-diameter pipe joints, oblique transition pipes and small-diameter pipe joints. The large-diameter pipe joints are used to plug in large-diameter pipes, and the small-diameter pipe joints are used to plug in small-diameter pipes. The oblique transition pipe plays a connecting role between the large-diameter pipe joints and the small-diameter pipe joints. These reducers are basically one-to-one.

[0003] In the prior art, when processing each reducer pipe, workers are required to fix it. However, since the reducer is small in shape and the outer diameters and lengths at both ends are different, the conventional clamping and fastening structure cannot fix the two ends of the reducer, which can easily cause the pipe joint to loosen during the processing, resulting in unsatisfactory processing effect of the pipe joint. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides an auxiliary device for processing reducer pipe joints, which overcomes the deficiencies of the prior art and effectively solves the problem that the conventional clamping and fastening structure in the prior art cannot fix the two ends of the reducer pipe joint, which easily causes the pipe joint to loosen during the processing.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An auxiliary device for processing a reducing pipe joint comprises a base plate, a support rod is fixed on the top of the base plate, and a fixed shell is fixed on the top of the support rod, both ends of the fixed shell are rotatably connected with screw rods, and the rod walls of the two screw rods are respectively screwed with clamping mechanisms, and the clamping mechanism comprises a connecting shell, a movable block fixed to the back of the connecting shell, a bidirectional screw rod rotatably connected to the inner walls of both ends of the connecting shell, and a clamping assembly screwed to both ends of the rod wall of the bidirectional screw rod.

[0007] According to the length of the reducer, rotate the two screws respectively to adjust the position between the two clamping mechanisms so that the positions of the two clamping mechanisms match the positions of the two ends of the reducer. Then rotate the two-way screws in the two clamping mechanisms respectively to adjust the two clamping assemblies to be close to each other so that the two clamping assemblies can clamp the two ends of the reducer respectively, which is convenient for subsequent processing operations.

[0008] Preferably, knobs are respectively provided at both ends of the fixing shell, and the two knobs are respectively connected and fixed to ends of the two screw rods that are away from each other.

[0009] The screw rod is rotated by turning the knob, thereby adjusting the positions of the two clamping mechanisms respectively.

[0010] Preferably, the movable block is threadedly connected to the screw rod, and the movable block is slidably connected to the fixed shell.

[0011] Through the threaded cooperation between the movable block and the screw rod, the rotating screw rod drives the movable block to move along the fixed shell.

[0012] Preferably, a turning handle is provided at the top end of the connecting shell, and the turning handle is connected and fixed to the top end of the bidirectional screw rod.

[0013] The bidirectional screw rod is driven to rotate by rotating the turning handle, thereby adjusting the position between the two clamping components.

[0014] Preferably, the clamping assembly includes an adjusting block, an inserting block plugged into one end of the adjusting block, and a clamping block fixed to one end of the inserting block.

[0015] The clamping block is connected to the adjusting block through an insert block, so that clamping blocks of different sizes can be easily replaced.

[0016] Preferably, the adjustment block is threadedly connected to the bidirectional lead screw, and the adjustment block is slidably connected to the connecting shell.

[0017] The rotating bidirectional screw drives the two adjusting blocks to move closer to or farther from each other, thereby clamping or loosening the pipe joint through the two clamping blocks.

[0018] The beneficial effects of the utility model are:

[0019] By rotating the two screws according to the length of the reducer, the position between the two clamping mechanisms is adjusted so that the positions of the two clamping mechanisms match the positions of the two ends of the reducer, and then the two-way screws in the two clamping mechanisms are rotated respectively to adjust the two clamping assemblies to be close to each other, so that the two clamping assemblies can clamp the two ends of the reducer respectively, which is convenient for subsequent processing operations. This effectively solves the problem that the conventional clamping and fastening structure in the prior art cannot fix the two ends of the reducer, which easily causes the pipe joint to loosen during the processing.
