Abstract
Description
Technical Field
[0001] The utility model relates to the field of pipe cutting machines, and more specifically, to a clamping mechanism of a pipe cutting machine. Background Art
[0002] The clamping mechanism of a pipe cutter refers to the parts or devices used to fix and clamp the pipe in the pipe cutter. These mechanisms are usually designed to firmly clamp the pipe to ensure that the pipe does not move or deform during the cutting process, thereby ensuring the accuracy and stability of the cutting. The design of the clamping mechanism can vary depending on the model of the pipe cutter and the use requirements, but the basic function is to effectively fix the pipe for accurate cutting operations.
[0003] The pipe cutting machine can cut pipes of different diameters. When cutting pipes of smaller diameters, in order to increase cutting efficiency, multiple small pipes are usually placed on the clamping mechanism at the same time for synchronous cutting. However, if the end faces of several pipes are not aligned, it will cause length errors of the pipes during the first section cutting. The existing clamping mechanism does not provide a structure for aligning the end faces of multiple pipes.
[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0007] The utility model is further configured as follows: a connecting block is fixedly connected to the base, a through hole is provided on the connecting block, a rotating hole is provided on the alignment plate, and a rotating column passes through both the rotating hole and the through hole.
[0008] The utility model is further configured as follows: one end of the rotating column is fixedly connected to the limiting part, the end of the rotating column facing away from the limiting part is detachably connected to the limiting block, and a convex strip that interferes with the limiting part is fixedly connected to the base, and the convex strip is used to limit the rotation of the limiting part.
[0009] The utility model is further configured as follows: the limiting mechanism comprises a clamping block and two grooves, the two grooves are located on the same vertical line, the clamping block is fixedly connected to the limiting block, and the grooves are located on the hole wall of the through hole.

[0014] In summary, the utility model has the following beneficial effects:
[0015] By arranging an upper clamping block and a lower clamping block on the base, the clamping mechanism can clamp the pipe fittings.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] The clamping mechanism of the pipe cutting machine, such as Figures 1 to 3 As shown, it includes a base 1, on which an upper clamping block 2 and a lower clamping block 3 are provided, and an alignment plate 4 is rotatably connected to the base 1, and the rotation angle of the alignment plate 4 is 180°. A limiting mechanism is provided on the base 1, and the limiting mechanism is used to limit the alignment plate 4 to be perpendicular to the base 1. By arranging the upper clamping block 2 and the lower clamping block 3 on the base 1, the clamping mechanism can clamp the pipe fitting. When the alignment plate 4 on the base 1 is flipped upward and is perpendicular to the base 1, the limiting mechanism can limit the alignment plate 4, and then the operator can push a number of pipe fittings so that their end faces contact the alignment plate 4, thereby aligning the pipe fittings, and then the upper clamping block 2 and the lower clamping block 3 clamp these pipe fittings, and then the pipe fittings can be cut. The alignment plate 4 is made of stainless steel, and the stainless steel material is corrosion-resistant, which increases the life of the alignment plate 4.
[0022] like Figure 2 and Figure 3 As shown, a connecting block 5 is integrally formed on the base 1, a through hole 6 is provided on the connecting block 5, a rotating hole 7 is provided on the alignment plate 4, and a rotating column 8 passes through the rotating hole 7 and the through hole 6 at the same time, so that the alignment plate 4 can rotate on the base 1, one end of the rotating column 8 is fixedly connected to the limiting portion 18, and the end of the rotating column 8 facing away from the limiting portion 18 is detachably connected to the limiting block 11, so that the rotating column 8 can keep passing through the through hole 6, and the limiting block 11 can be disassembled, and then the rotating column 8 can be passed through the through hole 6 and rotated to complete the installation, a protrusion 17 that contacts the limiting portion 18 is integrally formed on the base 1, and the protrusion 17 is used to limit the rotation of the limiting portion 18, and the cross-section of the limiting portion 18 is triangular, so that when the limiting portion 18 contacts the protrusion 17, the rotation of the rotating column 8 is limited.
[0023] like Figure 2 and Figure 3 As shown, the limiting mechanism includes a block 9 and two grooves 10, the two grooves 10 are located on the same vertical line, the block 9 is integrally formed on the limiting block 11, and the groove 10 is located on the hole wall of the through hole 6, so that when the block 9 is inserted into the groove 10, the alignment plate 4 is fixed. Since the grooves 10 are located in the same straight line, after the block 9 of the rotating column 8 slides out of the groove 10, the alignment plate 4 can be rotated, and then the block 9 is inserted into another groove 10, and then the block 9 fixes the alignment plate 4 again, so that the alignment plate 4 can rotate 180 degrees. A compression spring 12 is sleeved on the rotating column 8, and the compression spring 12 is located between the limiting portion 18 and the connecting block 5, so that when the rotating column 8 is pulled, the compression spring 12 will be squeezed by the limiting portion 18 and then elastically deformed, and the length of the compression spring 12 becomes shorter. Then the operator can rotate the alignment plate 4. When the alignment plate 4 rotates 180°, the operator releases the rotating column 8, and then the compression spring 12 recovers the elastic deformation and applies a force to the limiting portion 18, so that the rotating column 8 is reset, so that the clamping block 9 remains stuck in the groove 10.
[0024] like Figure 2 and Figure 3 As shown, the limit block 11 is provided with an opening 13 through which the rotating column 8 passes, and four convex strips 14 are integrally formed on the hole wall of the opening 13. The rotating column 8 is provided with four card slots 15 for the convex strips 14 to be embedded, so that the limit block 11 can be sleeved on the rotating column 8, and when the convex strips 14 are embedded in the card slots 15, the rotation of the limit block 11 can be limited. The rotating column 8 is threadedly connected with a nut 16 facing away from the limiting portion 18. When the nut 16 is fixed on the rotating column 8, the limit block 11 is kept on the rotating column 8, and during installation. When aligning the plate 4, the operator first sets the compression spring 12 on the rotating column 8, and then the operator picks up the alignment plate 4 so that the rotating hole 7 on the alignment plate 4 is aligned with the through hole 6 on the connecting block 5, and then the operator picks up the rotating column 8 to pass through the through hole 6 and the rotating through hole 6, and then the operator sets the limit block 11 on the part of the rotating column 8 extending outward, so that the convex strip 14 on the hole wall of the opening 13 is embedded in the card groove 15, and then the operator takes out the nut 16 and fixes it on the rotating column 8, thereby realizing the fixation of the nut 16 to the limit block 11.
[0025] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
