Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, and in particular to a non-magnetic pipe cutting device that can be quickly positioned. Background Technology

[0002] Non-magnetic pipes refer to pipes with a magnetic permeability close to or equal to the vacuum magnetic permeability, which hardly produce magnetization in a magnetic field.

[0003] In existing technologies, when cutting pipes, especially during temporary operations such as mobile work or outdoor construction, operators will draw cutting auxiliary lines on the outer wall of the pipe after measurement, and then use mobile cutting equipment, such as an angle grinder, to perform the cutting.

[0004] Traditional cutting equipment only provides a cutting platform and lacks the function of quickly positioning the pipe, which leads to the inability to guarantee the stability and accuracy of the cutting process and low work efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a non-magnetic pipe cutting device that can be quickly positioned.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A non-magnetic pipe cutting device with rapid positioning includes a base, an electric cutting machine is installed on one side of the upper part of the base, and a movable plate is provided on the side away from the electric cutting machine. The movable plate is connected to a lead screw to achieve horizontal displacement.

[0008] A rocker arm is rotatably mounted on one side of the upper part of the movable plate via a rotating seat. An arc-shaped pressure block is mounted on the bottom side of one side of the rocker arm. A handle is vertically mounted on one end of the rocker arm, and a control switch is provided on the top of the handle. The control switch is electrically connected to an electromagnet. The electromagnet is mounted on the rotating end of the rocker arm, and a magnetic sheet is provided on the side away from the electromagnet. When the control switch is turned on, the electromagnet is energized, and the magnetic sheet is displaced by electromagnetic attraction and is attracted to the electromagnet.

[0009] In addition, a preferred structure is that a rotating seat two is installed on the upper side of the base, and a rocker arm is rotatably connected to the middle of the rotating seat two through a rotating shaft and bearing components, and an electric cutting machine is installed at one end of the rocker arm.

[0010] In addition, a preferred structure is that a torsion spring is installed at the rotatable connection between the rocker arm and the rotating seat, and the torsion spring deforms when the rocker arm rotates.

[0011] In addition, a preferred structure is that a slot is provided on the upper side of the base, and a base is installed in the slot. The bottom of the base is screwed to the threaded section in the middle of the lead screw, and the smooth sections at both ends of the lead screw are rotatably installed on the inner wall of the slot.

[0012] In addition, a preferred structure is that mounting seats are installed on both sides of the upper part of the movable plate, and a pair of support rollers are fixedly installed on the upper part of the mounting seats.

[0013] In addition, in a preferred structure, the middle part of the rotating seat is rotatably connected to a support shaft via a bearing, the middle part of the support shaft is fixedly connected to the bottom end of the rocker arm, a slot is opened on one side of the inner wall of the rotating seat, a magnetic sheet is installed in the slot, one end of the magnetic sheet is provided with a limit post, the limit post extends into the interior of the rotating seat and is connected to a spring, and when the magnetic sheet moves through the slot, the spring deforms.

[0014] In addition, a preferred structure is that an electromagnet is fixedly installed inside the bottom side of the rocker arm, and the electromagnet is electrically connected to the control switch through a wire. In the natural state, there is a gap between the electromagnet and the magnetic plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] In this invention, pipe positioning is achieved through the coordinated arrangement of a rocker arm and a support roller. After rotation, the rocker arm presses against the outer wall of the pipe for positioning. Once pressed, the rocker arm is locked by an electromagnetic locking mechanism controlled by a control switch, ensuring the stability and convenience of the pipe positioning process. At the same time, the pipe can still be horizontally adjusted and positioned a second time by rotating the lead screw, effectively improving the convenience of positioning and increasing work efficiency.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-8 A non-magnetic pipe cutting device with rapid positioning includes a base 1, an electric cutting machine 13 is installed on one side of the upper part of the base 1, and a moving plate 2 is provided on the side away from the electric cutting machine 13. The moving plate 2 is connected to a lead screw 4 to achieve horizontal displacement.

[0028] A rocker arm 51 is rotatably mounted on one side of the upper part of the movable plate 2 via a rotating seat 5. An arc-shaped pressure block 55 is mounted on the bottom side of one side of the rocker arm 51. A handle 52 is vertically mounted on one end of the rocker arm 51. A control switch 53 is provided on the top of the handle 52. The control switch 53 is electrically connected to the electromagnet 7. The electromagnet 7 is installed on the rotating end of the rocker arm 51. A magnetic sheet 8 is provided on the side away from the electromagnet 7. When the control switch 53 is turned on, the electromagnet 7 is energized, and the magnetic sheet 8 is displaced by electromagnetic attraction and attracted to the electromagnet 7.

[0029] A rotating seat 11 is installed on one side of the upper part of the base 1. A rocker arm 12 is rotatably connected to the middle of the rotating seat 11 through a rotating shaft and bearing components. An electric cutting machine 13 is installed at one end of the rocker arm 12. The electric cutting machine 13 is connected to an external power supply to realize the function of powering the electric cutting machine 13.

[0030] A torsion spring 14 is installed at the rotatable connection between the rocker arm 12 and the rotating seat 11. When the rocker arm 12 rotates, the torsional force generated by the deformation of the torsion spring 14 drives the rocker arm 12 to rotate and return to its original position.

[0031] A slot is provided on one side of the upper part of the base 1. The base 1 is installed in the slot and the bottom of the base 1 is screwed to the middle threaded section of the lead screw 4. The smooth sections at both ends of the lead screw 4 are rotatably installed on the inner wall of the slot.

[0032] One end of the lead screw 4 extends out of the base 1 and is connected to a handle. The handle drives the lead screw 4 to rotate, and its threaded section rotates in a spiral motion with the base 1 to move the base 1.

[0033] The bottom of the base 1 has a protrusion for fitting into the slot provided on the upper part of the base 1.

[0034] Mounting bases 3 are installed on both sides of the upper part of the movable plate 2. A pair of support rollers 31 are fixedly installed on the upper part of the mounting bases 3, and the pipes are placed on the support rollers 31.

[0035] A support shaft 6 is rotatably connected to the middle of the rotating seat 5 via a bearing. The middle of the support shaft 6 is fixedly connected to the bottom end of the rocker arm 51. A slot is opened on one side of the inner wall of the rotating seat 5. A magnetic piece 8 is installed in the slot. A limit post 82 is provided at one end of the magnetic piece 8. The limit post 82 extends into the interior of the rotating seat 5 and is connected to a spring 81. When the magnetic piece 8 moves through the slot, the spring 81 deforms.

[0036] An electromagnet 7 is fixedly installed inside the bottom side of the rocker arm 51. The electromagnet 7 is electrically connected to the control switch 53 through the wire 54. In its natural state, there is a gap between the electromagnet 7 and the magnetic plate 8.

[0037] In this embodiment, the pipe is placed on the support roller 31 on the upper part of the moving plate 2, supported by the support roller 31. The operator holds the handle 52 and pulls the rocker arm 51 to rotate the pipe. During the rotation, the arc-shaped pressure block 55 moves and presses down on the outer wall of the pipe. When the pipe is pressed down and cannot move, the operator simply presses the control switch 53 on the handle 52 with his thumb, causing it to deflect to the open state, i.e., the circuit is connected. At this time, the corresponding line connected to the electromagnet 7 is connected, and the electromagnet 7 generates a corresponding electromagnetic attraction force after being energized. The magnetic sheet 8 inside the rotating seat 5 is attracted and displaced by the magnetic attraction until it is attracted to the electromagnet 7. At this time, the magnetic sheet 8 and the electromagnet 7 are connected as a whole. Since the magnetic sheet 8 is installed inside the rotating seat 5 through multiple limiting posts 82, the setting of the limiting posts 82 allows the magnetic sheet 8 to make horizontal displacement but not rotational movement. Therefore, after the electromagnet 7 is connected to the magnetic sheet 8, the rocker arm 51 used to install the electromagnet 7 cannot rotate as a whole, thus maintaining the corresponding position to press the pipe.

[0038] Then, the operator starts the electric cutting machine 13 and holds the electric cutting machine 13 to make it rotate downward through the rocker arm 12, thereby cutting the pipe.

[0039] In practical applications, after the pipe is fixed, the moving plate 2 can still be moved by rotating the screw 4, thereby moving the pipe horizontally to meet the cutting position.

[0040] The control switch 53 is marked with corresponding on and off indicators, and is electrically connected to the relay, external power supply, and electromagnet 7 via wire 54 to form a control circuit.

[0041] It is worth noting that the control switch 53 can be purchased directly from the market, and its specific circuit wiring method is common knowledge to those skilled in the art and will not be explained further.

[0042] It should also be noted that the electric cutting machine 13 is a device that uses a motor to drive the cutting blade to rotate and achieve cutting. This is existing technology and will not be explained further.

[0043] After the rocker arm 51 is rotated, it can press and position the outer wall of the pipe. The control switch 53 can make the electromagnet assembly at the rotating end of the rocker arm 51 magnetically lock to realize the quick locking function of the rocker arm 51, thereby quickly pressing and positioning the pipe. At the same time, the pipe can still be adjusted and positioned horizontally after being positioned by rotating the lead screw 4.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
