Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe cutting machines, and specifically relates to a positioning device for a pipe cutting machine. Background Technique
[0002] The main function of a pipe cutting machine is to cut tubular materials according to specific lengths or shapes to meet the requirements of subsequent processing or installation. It can achieve precise cutting of pipes according to preset dimensions, ensure that the cut materials meet the design specifications, and can perform rapid continuous cutting to improve production efficiency. In short, the pipe cutting machine plays an indispensable role in modern industrial production. It not only improves production efficiency and product quality but also helps to reduce costs and enhance the market competitiveness of enterprises.
[0003] However, in the current existing technology, the cutting blade will be worn during long-term use when cutting pipes. When the severely worn area contacts the pipe during the cutting process, it will cause the pipe to move, resulting in vibration during the pipe cutting process, causing deviation between the pipe angle and the cutting angle of the pipe cutting machine, affecting the cutting angle and accuracy, and reducing the cutting quality. Content of the Utility Model
[0004] The purpose of the utility model is to provide a positioning device for a pipe cutting machine to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution:
[0006] A positioning device for a pipe cutting machine includes a cutting table. A positioning wheel is arranged inside the cutting table. A base is arranged on one side of the cutting table. A positioning component for positioning during pipe cutting is arranged outside the base. The positioning component includes a hole groove arranged inside the base. Two auxiliary wheels are arranged inside the hole groove. Two cavities are arranged on the outer walls of the two auxiliary wheels. A signal button and a spring are arranged on the inner wall of the cavity. A convex block is arranged inside the cavity. Connecting frames and covers are arranged at both ends of the base. An extension rod is arranged inside the connecting frame. A pulley is arranged on the inner wall of the cover. An electromagnet is arranged at one end of the cover.
[0007] As a preferred scheme of the utility model, the positioning wheel is located directly below the cutter in the cutting table and is rotationally connected to the cutting table through a connecting shaft. The base is located at the pipe placement area on one side of the cutting table and is connected to the cutting table through bolts.
[0008] As a preferred scheme of the utility model, the auxiliary wheels are both rotationally connected to the inner wall of the hole groove of the base through connecting shafts, and the auxiliary wheels are parallel to the positioning wheel in the cutting table in terms of angle. Both the positioning wheel and the auxiliary wheels support the pipe and are in contact with the outer wall of the pipe.
[0009] As a preferred embodiment of the present utility model, the two cavities are annularly distributed on both sides of the outer wall of the auxiliary wheel. One end of the convex block is located inside the cavity, and the other end extends to the outside of the auxiliary wheel. Both ends of the spring are connected to the inner wall of the cavity and the convex block by welding.
[0010] As a preferred embodiment of the present utility model, the signal button is located on the inner wall of the cavity and is electrically connected to the total control center. When the convex block contracts inside the cavity near the inner end, it abuts against and presses the signal button.
[0011] As a preferred embodiment of the present utility model, the connecting frame is of a segmented structure, and the extension rod is located inside the connecting frame and is slidably connected to the inner wall of the connecting frame. Both ends of the connecting frame are respectively rotatably connected to the base and the cover plate through damping shafts. The electromagnet is inlaid and connected to the end of the cover plate far from the connecting frame. By rotating the connecting frame, the cover plate wraps around the pipe.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: In response to the problems raised in the background art, this application adopts a positioning component. By extending the base at the front end of the cutting table, the position of the pipe is positioned by the parallel-mounted positioning wheels and the auxiliary wheel group. The angle of the pipe is positioned by comparing the fitting surfaces of the pipe with the two wheel groups. At the same time, by extending the cover plates at both ends of the auxiliary wheel group, after the pipe is positioned, the pipe is wrapped and tightened by the connecting frame to improve the stability during pipe cutting. During the cutting process, through the convex blocks protruding from the auxiliary wheel, when cutting, by cooperating with the rotation of the pipe, the pipe rotates relative to the auxiliary wheel and presses the convex blocks. When the angle of the pipe deflects, the convex blocks cannot fully contract, and a signal is sent for reminder, improving the cutting accuracy.
[0013] The present utility model positions and assists in correcting the pipe through two wheel groups, wraps and tightens the pipe during cutting to improve the cutting stability, avoids the pipe from shaking, and ensures the cutting quality and accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described.
[0020] Embodiment
[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: a positioning device for a pipe cutting machine, including a cutting table 1. A positioning wheel 2 is arranged inside the cutting table 1. The positioning wheel 2 is used to position the area of the pipe that needs to be cut. A base 3 is arranged on one side of the cutting table 1. A positioning component for positioning during pipe cutting is arranged outside the base 3. The positioning component includes a hole groove 301 arranged inside the base 3. Two auxiliary wheels 4 are arranged inside the hole groove 301. The auxiliary wheels 4 are parallel to the positioning wheel 2 and are used to position the pipe body area near the cutting position of the pipe. After the pipe is placed, the angle of the pipe is assisted to be positioned and corrected by comparing the fitting situation of the pipe with the positioning wheel 2 and the auxiliary wheels 4 (during cutting, the pipe can be driven to rotate by the positioning wheel 2 and the auxiliary wheels 4, which is convenient for cutting). Two cavities 5 are arranged on the outer walls of the two auxiliary wheels 4 for accommodating the bumps 6. A signal button 501 and a spring 502 are arranged on the inner wall of the cavity 5. During the cutting process, since both the auxiliary wheel 4 and the pipe are in a rotating state, the bump 6 outside the auxiliary wheel 4 will cycle through the pipe. When passing through the pipe, it can contract into the cavity 5 by abutting against the pipe, and press the signal button 501 in the cavity 5 after contraction (when the angle of the pipe deflects, since it cannot fit completely with the auxiliary wheel 4, when pressing the bump 6, the bump 6 will not completely contract into the cavity 5, so the pressing force of the bump 6 on the signal button 501 is insufficient, and the signal button 501 emits a signal to the control center for reminder) The cavity 5 is provided with a bump 6 inside. Connecting frames 7 and cover plates 8 are arranged at both ends of the base 3. The connecting frame 7 enables the cover plate 8 to rotate, thereby wrapping the pipe. At the same time, the diameter after the cover plate 8 is wrapped can be tightened by the segmented telescopic structure of the connecting frame 7, and the pipe is tightened and clamped after wrapping to improve the stability of the pipe. An extension rod 701 is arranged inside the connecting frame 7. A pulley 801 is arranged on the inner wall of the cover plate 8. An electromagnet 802 is arranged at one end of the cover plate 8. The electromagnet 802 can adsorb and fix when the cover plate 8 wraps the pipe.
[0022] In this embodiment, all electrical components are controlled by a conventional controller.
[0023] For the embodiments, please refer to Figures 1-4 , the positioning wheel 2 is located directly below the cutter in the cutting table 1 and is rotatably connected to the cutting table 1 through a connecting shaft. The base 3 is located at the pipe placement area on one side of the cutting table 1 and is connected to the cutting table 1 by bolts. The auxiliary wheels 4 are each rotatably connected to the inner wall of the hole groove 301 of the base 3 through a connecting shaft, and the auxiliary wheels 4 are parallel to the positioning wheel 2 in the cutting table 1 in terms of angle. Both the positioning wheel 2 and the auxiliary wheels 4 receive the pipe and are in contact with the outer wall of the pipe. The two cavities 5 are annularly distributed on both sides of the outer wall of the auxiliary wheel 4. One end of the convex block 6 is located inside the cavity 5, and the other end extends outside the auxiliary wheel 4. Both ends of the spring 502 are connected to the inner wall of the cavity 5 and the convex block 6 by welding. The signal button 501 is located on the inner wall of the cavity 5 and is electrically connected to the total control center. When the convex block 6 contracts inside the cavity 5, it abuts against and presses the signal button 501. The connecting frame 7 is a segmented structure, and the extension rod 701 is located inside the connecting frame 7 and is slidably connected to the inner wall of the connecting frame 7. Both ends of the connecting frame 7 are respectively rotatably connected to the base 3 and the cover plate 8 through damping shafts. The electromagnet 802 is embedded in the end of the cover plate 8 away from the connecting frame 7, and the cover plate 8 is wrapped around the pipe by rotating the connecting frame 7. During use, first place the pipe on the cutting table 1, and position and fit the pipe with the positioning wheel 2 and the auxiliary wheels 4. Drive the pipe to rotate correspondingly through the rotation of the positioning wheel 2 and the auxiliary wheels 4. It is convenient to correct and position the angle of the pipe according to the fitting situation of the pipe. After angle positioning, lift the cover plate 8, wrap the cover plate 8 around the pipe through the connecting frame 7, and fix it by adsorbing with the electromagnet 802 at one end of the cover plate 8. Then, control the contraction of the extension rod 701 in the connecting frame 7 through the PLC controller to tighten and fix the pipe with the cover plate 8. Then, cooperate with the cutter of the cutting table 1 to cut the pipe.
