Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cutting equipment, in particular to a positioning and fixing track structure of a pipeline cutting machine. Background Art

[0002] Electric automatic pipe cutting machines have become a common tool in current pipe cutting operations. These cutting machines are usually fixed to the pipe by chains and rely on rollers to rotate along the pipe wall to perform cutting operations. However, there is a significant problem with this existing design: due to the relatively short spacing between the chain and the roller, the machine is prone to shaking during the cutting process. This shaking not only affects the accuracy and flatness of the cutting, but may also cause deviations or unevenness in the cut.

[0003] When the cut is not smooth, secondary cutting or manual cutting correction is often required, which not only increases the workload and difficulty of operation, but also may cause waste of pipe materials. In the modern industrial environment that pursues high efficiency, precision and resource conservation, such waste and inefficiency are obviously unacceptable. Therefore, in view of the shortcomings of the existing electric automatic pipe cutting machine in terms of stability and accuracy, a new type of positioning fixed track structure is urgently needed to improve the quality and efficiency of pipe cutting. Utility Model Content

[0004] The utility model aims to provide a positioning and fixing track structure for a pipe cutting machine, so as to solve the problem in the background art that the interval between the chain and the roller is relatively short, which causes the machine to shake easily during the cutting process.

[0006] Preferably, the number of the limit assemblies is four, and two are arranged in a group on the outside of both sides of the track.

[0007] Preferably, the limiting assembly includes a vertically arranged sliding column, a protective cover is provided on the outer side of the bottom of the sliding column, a sliding cover is installed on the top of the sliding column, the sliding cover is slidably matched with the outer end of the bracket, a bolt hole is provided on the top of the sliding cover, a positioning bolt is installed in the through hole, the positioning bolt is threadedly connected to the bolt hole, and the bottom end of the positioning bolt is tightened against the outer wall of the bracket.

[0008] Preferably, a bolt hole is provided on a side of the fixing block close to the track, a plurality of locking holes are provided on the surface of the track, and the fixing block is fixed to the inner side of the track by locking bolts.

[0011] Preferably, the projection is a hemispherical structure.

[0012] Preferably, the fixing blocks are arranged in a circular shape with equal spacing on the inner side of the track.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The positioning and fixing track structure of the pipe cutting machine has a unique design and construction, which significantly improves the stability and accuracy of the pipe cutting operation. The structure uses the close fit of the bracket and the limit assembly to ensure that the cutting machine remains stable during operation, effectively reducing shaking and deviation.

[0023] The utility model provides a positioning and fixing track structure of a pipe cutting machine, such as Figure 1-Figure 5 As shown, it includes a bracket 3, one end of the bracket 3 is fixed to the cutting machine 2 by bolts, the cutting machine 2 is installed on the pipeline 1, and the other end of the bracket 3 is installed with a plurality of limit assemblies 4, one end of the pipeline 1 is sleeved with a track 5, and the limit assemblies 4 are arranged on both sides of the track 5. A plurality of fixing blocks 51 are installed on the inner side of the track 5, and a plurality of protrusions 53 are installed on the outer wall of the fixing block 51, and the protrusions 53 abut against the outer wall of the pipeline 1. The cutting machine 2 is firmly connected to the pipeline 1 through the bracket 3, and the accurate positioning of the track 5 is ensured by the limit assemblies 4. In particular, the design of the fixing block 51 and the protrusion 53 installed on the inner side of the track 5 makes the whole structure fit closely with the outer wall of the pipeline 1, greatly enhancing the stability during the cutting operation. This structure not only effectively prevents the possible shaking of the cutting machine during operation, but also ensures the accuracy of cutting and the flatness of the cut. Therefore, the structure significantly improves the quality and efficiency of pipeline cutting, reduces the waste of materials and subsequent correction work caused by unstable cutting, and brings substantial convenience and cost savings to pipeline construction and maintenance.

[0024] In this embodiment, there are four limit assemblies 4 , which are arranged in groups of two on the outside of both sides of the track 5 to ensure that the cutting machine 2 will not deviate when running around the pipe 1 .

[0025] Specifically, the limit assembly 4 includes a vertically arranged sliding column 41, a protective sleeve 42 is provided on the outer side of the bottom of the sliding column 41, a sliding sleeve 43 is installed on the top of the sliding column 41 to protect the sliding column 41, the sliding sleeve 43 is slidably matched with the outer end of the bracket 3, a bolt hole is provided on the top of the sliding sleeve 43, a positioning bolt 44 is installed in the through hole, the positioning bolt 44 is threadedly connected to the bolt hole, and the bottom end of the positioning bolt 44 is tightly pressed against the outer wall of the bracket 3.

[0026] Furthermore, a bolt hole is provided on one side of the fixing block 51 close to the track 5 , and a plurality of locking holes 55 are provided on the surface of the track 5 . The fixing block 51 is locked and fixed to the inner side of the track 5 by locking bolts 52 , so as to facilitate the arbitrary disassembly and assembly and position adjustment of the fixing block 51 .

[0027] Furthermore, a plurality of weight-reducing holes 54 are provided on the surface of the track 5 to reduce the weight of the track 5 , making it easier to carry and saving materials.

[0028] Furthermore, a groove 511 is provided on the surface of the fixing block 51 to save material usage.

[0030] Furthermore, the fixing blocks 51 are arranged in a circular shape with equal spacing on the inner side of the track 5 to ensure that the outer wall of the pipeline 1 is evenly stressed.

[0031] When the positioning and fixing track structure of the pipe cutting machine of the utility model is used, first, one end of the bracket 3 is tightly fixed to the cutting machine 2 by bolts, so that the cutting machine 2 can be firmly installed on the pipe 1. The other end of the bracket 3 is connected to the limit assembly 4, which is precisely set on both sides of the track 5 to ensure that the cutting machine will not deviate during operation.

[0032] When the cutting machine starts working, it moves along the outer wall of the pipe 1.

These fixing blocks 51 and protrusions 53 fit tightly with the outer wall of the pipe 1 and provide a stable support.

[0033] In addition, the cooperation between the slide post 41 and the slide sleeve 43 in the limiting assembly 4 enables the cutting machine to slide smoothly on the track, while the positioning bolt 44 further ensures the position stability of the cutting machine.
