Description

Technical Field

[0001] The present invention belongs to the technical field of cylindrical and plate cutting, and relates to the stabilization of cutting tools, and specifically to a stabilization device for cylindrical and plate cutting tools and a method of using the same. Background Art

[0002] At present, when cutting iron plates and medium and low pressure carbon steel pipes in factories and mines, workers usually hold a cutting torch and cut along the cutting direction. Because the worker holds the cutting torch during the cutting process, affected by the worker's heartbeat and cutting experience, the edge of the iron plate or carbon steel pipe will be uneven after cutting, and the accuracy of the size of the iron plate and carbon steel pipe after cutting cannot be guaranteed, which affects the quality of the finished product and increases the number of unqualified cut parts. For cut parts with unqualified sizes, workers need to spend time and materials to grind the uneven cutting surface formed by cutting, which is time-consuming and labor-intensive, not only increasing labor costs, but also reducing processing efficiency.

[0003] Most of the stabilizing devices for cutting tools in the prior art are only used for cutting circular plates or cylindrical pipes.

[0004] The stabilizing device for cutting circular plates includes a center positioning seat, a stabilizing seat and a cutting nozzle fixing ring which are fixedly connected from left to right by adjusting the crossbar. When cutting, the cutting nozzle is placed in the cutting nozzle fixing ring, and the cutting nozzle fixing ring rotates around the center positioning seat to cut the circular plate. This cutting structure and method is only suitable for cutting circular plates. It cannot provide sufficient support when cutting cylindrical parts and plates with flat cutting surfaces, and cannot meet the requirements for cutting finished products.

[0005] For the stabilizing device used for cutting cylindrical pipe fittings, the pipe fittings are mostly rotated and fixed on the support frame, and the cutting tool is fixed on the connecting frame. When cutting, the cutting tool is fixed, and the pipe fitting is driven to rotate by the support frame to achieve the cutting of the pipe fitting. This cutting structure and method is only suitable for cutting circular pipe fittings, not for cutting plates with flat cutting surfaces. In addition, the overall structure is relatively complex, occupies a large area, and is relatively inconvenient to use. Summary of the invention

[0006] In order to solve the above deficiencies in the prior art, the present invention aims to provide a stabilizing device for cylindrical and plate cutting tools and a method of using the same, so as to achieve the purpose of being suitable for cutting both cylindrical parts and plates with flat cutting surfaces.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a stabilizing device for cylindrical and plate cutting tools, comprising a connecting rod, one side of the connecting rod is fixedly connected to a cutting fixing piece for fixing the cutting part of the cutting tool, and the other side of the connecting rod is rotatably connected to two rollers for rolling on the surface of the cut workpiece along the cutting direction.

[0008] As a limitation of the present invention, the rollers are all rotatably connected to the roller frames, and the roller frames are all detachably connected to the connecting rods.

[0009] As a further limitation of the present invention, the distances from the contact points of the two rollers with the cut pieces to the connecting rod are equal.

[0010] As a further limitation of the present invention, the two roller frames are a first roller frame for fixing the first roller and a second roller frame for fixing the second roller, the first roller frame is provided with a threaded hole for threaded connection with a connecting rod, and the first roller frame is threadedly connected with a top screw for tightening the connecting rod into the threaded hole.

[0011] As a further limitation of the present invention, a support portion for fixing the cutting tool is provided on the second roller frame, and the first roller frame is located between the second roller frame and the cutting fixing member.

[0012] As another limitation of the present invention, the second roller frame includes two symmetrically arranged clamping plates connected by bolts, and a limiting sleeve for limiting the distance between the two clamping plates is sleeved on the bolts between the two clamping plates; the second roller is rotatably connected to the bottom ends of the two clamping plates, the middle parts of the two clamping plates are clamped on the connecting rod, and the supporting parts arranged on the top ends of the two clamping plates are circular clamps for clamping and fixing cutting tools.

[0013] As another limitation of the present invention, the cutting fixture is a sleeve, on which a fixing nut threadedly connected to a connecting rod is fixedly connected, and on the connecting rod is an adjustable nut threadedly connected to limit the fixing nut.

[0014] The present invention also provides a method for using a stabilizing device for cylindrical and plate cutting tools, which is realized by utilizing the above-mentioned stabilizing device for cylindrical and plate cutting tools, and its technical solution is as follows: A method for using a stabilizing device for cylindrical and plate cutting tools, comprising the following steps: two rollers roll along the cutting direction on the surface of the cut piece, driving the cutting part of the cutting tool placed in the cutting fixture to cut along the cutting direction.

[0015] As a limitation of the present invention, S1. Pre-adjustment: adjust the position of the roller on the connecting rod, and adjust the rotation angle of the sleeve relative to the connecting rod; S2. Cutting: the cutting tool body is placed on the support part, and the two rollers slide along the cutting direction on the surface of the cut piece, driving the cutting part of the cutting tool fixed in the sleeve to cut along the cutting direction.

[0016] Due to the adoption of the above-mentioned technical scheme, the beneficial effects achieved by the present invention compared with the prior art are as follows: the present invention effectively ensures the cutting accuracy of the cut workpiece and the quality of the cut product by providing stable support for the cutting tool when it moves along the cutting line direction, so that the cut cross-section of the cut workpiece is smooth, the number of unqualified cut products is reduced, and secondary processing such as grinding of the cut surface is avoided, thereby improving work efficiency.

[0017] The present invention provides at least two rollers, which can drive the cutting fixture of the cutting part of the cutting tool to move linearly when cutting a flat plate; and can drive the cutting fixture to cut in a circumferential direction perpendicular to the side of the cylindrical part when cutting a cylindrical part. In addition, the fixed position of the roller frame on the connecting rod of the present invention is adjustable, which can be suitable for processing cylindrical parts of different diameters, and can adjust the support point of the roller on the supporting rod for the cutting tool according to the center of gravity position of the supported cutting tool.
