Description

Technical Field

[0001] The utility model belongs to the technical field of cutting equipment, and particularly relates to a cutting machine convenient for positioning. Background Art

[0002] For a cutting machine for pipes, when in use, it is necessary to position and cut the pipes according to the length required for construction. Therefore, first, according to the length of the pipe to be cut, marks are made on the pipe with a marker pen, and then the cutting machine cuts at the marked position of the pipe. The process of marking the length of each pipe one by one will delay the construction progress and affect the work process. In addition, when the pipe is being cut, a clamp needs to be used for fixation. When the grinding wheel cuts the pipe, the pipe will jump violently due to the intense cutting. To prevent the jumping of the pipe from affecting the error of the cutting length, the operator needs to press it with hands or feet, making the operation inconvenient for the operator.

[0003] Therefore, we provide a cutting machine convenient for positioning to solve the above problems. Content of the Utility Model

[0025] Embodiment 1

[0026] Please refer to Figures 1 to 5, the utility model is a cutting machine that is convenient for positioning, including a machine body 1, a positioner 2 and a measuring component 3. The machine body 1 includes a bottom plate 101, a motor cover 102, a motor 103, a grinding wheel 104 and a handle 105. The positioner 2 includes a positioner housing 201, a linear light motor 202, a linear light mirror 203 and a laser emitter 204. By placing the pipe on the bottom plate 101, the measuring component 3 measures the length of the pipe to be cut. The laser emitter 204 of the positioner 2 emits a linear laser, and then the linear light motor 202 rotates to drive the linear light mirror 203 to rotate, reflecting the laser out of the light passing port 201a, so that the light spot of the laser falling on the pipe is linear, so as to mark and position the cutting position, solving the problem of low work efficiency caused by the need to measure and mark before cutting the pipe.

[0027] Specifically, a rotating arm 102a is fixedly arranged on the outer side of the periphery of the motor cover 102. The handle 105 is fixedly installed on the outer side of the motor cover 102. One end of the rotating arm 102a is hinged to the upper end of the bottom plate 101. The grinding wheel 104 is fixedly installed on the output shaft of the motor 103. A cutting groove 101a is opened on the surface of the bottom plate 101 below the grinding wheel 104. The positioner 2 is fixedly installed at one end of the cutting groove 101a on the surface of the bottom plate 101. A light passing port 201a is opened on one side of the positioner housing 201 facing the cutting groove 101a. Both the laser emitter 204 and the linear light motor 202 are fixedly installed in the positioner housing 201. The laser emitting end of the laser emitter 204 is vertically downward. The linear light mirror 203 is fixedly installed on the output shaft of the linear light motor 202. The mirror surface of the linear light mirror 203 is perpendicular to the wheel surface of the grinding wheel 104. The linear light mirror 203 is below the emission ray of the laser emitter 204; the measuring component 3 is fixedly installed on the surface of the bottom plate 101 on the side of the cutting groove 101a far from the motor cover 102.

[0028] Further, the measuring component 3 includes a tape measure 301, a winding belt 302, a baffle 303 and a vertical plate 304. The vertical plate 304 is fixedly arranged on the surface of the bottom plate 101 on the side of the cutting groove 101a far from the motor cover 102. A notch 304a is opened on the surface of the vertical plate 304.

[0029] Further, the tape measure 301 is fixedly installed on the side of the vertical plate 304 away from the notch 304a. The winding belt 302 is wound in a winding box 302a. The winding box 302a is fixedly installed on the side of the vertical plate 304 away from the tape measure 301. The rack of the tape measure 301 and the outlet end of the winding belt 302 are both on the side of the vertical plate 304 close to the cutting groove 101a. One end of the tape of the tape measure 301 and one end of the winding belt 302 are respectively fixedly connected to both ends of the baffle 303.

[0030] The operation process of this embodiment is as follows:

[0031] Place the pipe on the bottom plate 101. Extend one end of the pipe out of the notch 304a and push out the baffle 303, so that the tape of the tape measure 301 is pulled out, enabling the operator to read the length of the pipe. The linear light motor 202 rotates to drive the linear light mirror 203 to rotate, causing the linear laser emitted by the laser emitter 204 to be refracted and emitted from the light passing port 201a, and finally forming a strip-shaped light spot on the pipe to facilitate the positioning and cutting of the grinding wheel.

[0032] Embodiment 2

[0033] Please refer to Figures 1 to 5 , on the basis of Embodiment 1, a clamp assembly 101b is provided below the motor cover 102 on the upper side of the panel of the bottom plate 101. The clamp assembly 101b includes a limit plate 101b-1, a lead screw channel 101b-2 and a lead screw 101b-3 fixed on the upper side of the panel of the bottom plate 101. By providing an inclined top plate 101b-4 at the front end of the lead screw 101b-3 of the clamp assembly 101b, the spiral lead screw 101b-3 is advanced to make the inclined top plate 101b-4 press tightly against the pipe and apply a downward pressure to the pipe, so that the pipe does not jump violently during cutting, thus affecting the cutting effect.

[0034] Specifically, the plate surface of the limit plate 101b-1 is perpendicular to the wheel surface of the grinding wheel 104. The lead screw 101b-3 is spirally sleeved in the lead screw channel 101b-2, and the axis of the lead screw 101b-3 is perpendicular to the panel of the limit plate 101b-1. The bottom plate 101 is provided with a top plate sliding groove 101c on the panel between the limit plate 101b-1 and the lead screw channel 101b-2 directly below the lead screw 101b-3.

[0037] Furthermore, a cutting machine button 105b is installed between the grip 105a-1 and the bottom plate of the U-shaped grip holder 105a.

[0038] The operation process of this embodiment is as follows:

[0039] Place the pipe on the bottom plate 101, rotate the lead screw 101b-1 to press the inclined top plate 101b-4 against the pipe, and apply a downward pressure to the pipe by the downward inclined panel to keep the pipe stable without jumping. The rubber pad 101b-5 further increases the friction force to prevent the pipe from sliding. The operator holds the handle 105a-1 with the hand and presses the cutting machine button 105b with the index finger, and presses down the handle 105. When the operator presses down the handle for cutting, the palm is downward, making it easier to exert force with the wrist during the downward pressing process.
