In this process, since the cutting disc is manually controlled to descend for cutting based on experience, it is easy for the cutting disc to tilt, which easily leads to an uneven cutting surface, which is not conducive to the later docking of the two rails. Utility Model Content

[0009] Preferably, a driving motor is installed on one side of the shell, and a supporting shaft is rotatably connected to the other side of the shell. The supporting shaft is linked to the output end of the driving motor through a pulley group, and the cutting disc is connected to the supporting shaft through screws.

[0010] Preferably, a locking mechanism is provided at the front end of the housing, and the locking mechanism consists of an outer frame, a pull-out frame, a locking frame and a return spring.

[0012] In summary, the utility model mainly has the following beneficial effects:

[0013] 1. The existing cutting machine controls the cutting disc to descend for cutting by manual experience, which makes it easy for the cutting disc to tilt and cause the cutting surface to be uneven, which is not conducive to the docking of the rails. The utility model is provided with a positioning mechanism and a guide mechanism, after the support frame is sleeved on the rail, the electric push rod is controlled to work and extend until the positioning plate is firmly fitted with the side wall of the rail, so that the positioning of the cutting machine body on the rail can be achieved through the positioning plate. Since the cutting machine body is connected to the first guide plate through the transverse frame and the second guide plate for transverse sliding, and is connected to the support frame through the longitudinal frame and the first guide plate for longitudinal sliding, and the first guide plate is connected to the second guide plate for rotation through the rotating shaft, the cutting machine body can be moved to multiple positions in the direction perpendicular to the rail. Through the above operation, the cutting disc and the rail can be always in a vertical state, so that the rail can be protected, thereby preventing the situation that the cutting surface of the rail is uneven due to tilted cutting, which is conducive to the docking of the two rails in the later stage.

[0014] 2. The utility model is provided with a locking mechanism. Since the pull-out frame is elastically connected to the outer frame by a reset spring, and the first guide plate and the second guide plate are rotationally connected by a rotating shaft, when the longitudinal frame is rotated to a horizontal state around the rotating shaft, the locking frame can be pulled to one side so that the locking frame is not blocked by the longitudinal frame. Since the locking frame and the pull-out frame are rotationally connected by a pin shaft, the locking frame can be rotated to be in a vertical state with the outer shell. At this time, the pull-out frame is released, so that the locking frame will be stuck on the outer surface of the longitudinal frame under the action of the reset spring and realize its positioning, thereby realizing the folding of the cutting machine, so that it can be convenient to move and carry.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0022] The following describes an embodiment of the utility model based on its overall structure.

[0023] A cutting machine with a protective structure, such as Figure 1 , Figure 3 and Figure 4 As shown, it includes a cutting machine body 1, which includes a shell 101 and a cutting disc 104. The cutting disc 104 is rotatably connected to one side of the shell 101. A driving motor 102 is installed on one side of the shell 101. A support shaft 103 is rotatably connected to the other side of the shell 101. The support shaft 103 and the output end of the driving motor 102 are linked through a pulley group. The cutting disc 104 is connected to the support shaft 103 through screws. When the driving motor 102 is working, the output end of the driving motor 102 drives the supporting shaft 103 and the cutting disc 104 to rotate under the action of the pulley group, and gradually moves downward to cut the rail.

[0024] See also Figure 1 and Figure 3It can be seen that the top end of the support frame 201 is rotatably connected to a roller 204, and two rollers 204 are symmetrically arranged about the central axis of the support frame 201. After the positioning plate 203 is separated from the side wall of the rail, the cutting machine body 1 can be pulled to slide along the rail, so that the cutting machine body 1 can be easily moved to the next position to be cut, and the process is relatively labor-saving.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that the front end of the housing 101 is provided with a guide mechanism 3, and the guide mechanism 3 includes a longitudinal frame 301, a first guide plate 302, a transverse frame 303 and a second guide plate 304. The transverse frame 303 is connected to the front end of the housing 101 by screws, and the second guide plate 304 is movably connected to the inside of the transverse frame 303. The first guide plate 302 is movably connected to the front end of the second guide plate 304. The longitudinal frame 301 is sleeved on the outer surface of the first guide plate 302. The housing 101 and the first guide plate 302 form a sliding structure through the transverse frame 303 and the second guide plate 304. The transverse frame 303 and the support frame 201 forms a sliding structure through the first guide plate 302 and the longitudinal frame 301, and a rotating shaft 305 is arranged between the second guide plate 304 and the first guide plate 302, and the second guide plate 304 and the first guide plate 302 form a rotating structure through the rotating shaft 305. After the cutting machine body 1 is positioned on the rail, the cutting machine body 1 can be moved to multiple positions in the direction perpendicular to the rail, so that the cutting disk 104 and the rail are always in a vertical state, so that the rail can be protected, thereby preventing the occurrence of inclined cutting that makes the cutting surface of the rail uneven, which is beneficial to the later docking of the two rails.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that a positioning mechanism 2 is provided at the bottom end of the longitudinal frame 301, and the positioning mechanism 2 includes a support frame 201, an electric push rod 202 and a positioning plate 203. The support frame 201 is connected to the bottom end of the longitudinal frame 301 by screws, and the electric push rod 202 is installed inside the support frame 201. The positioning plate 203 is connected to one side of the electric push rod 202 by screws. After the support frame 201 is sleeved on the rail, the electric push rod 202 is controlled to work and extend until the positioning plate 203 is firmly fitted with the side wall of the rail, so that the cutting machine body 1 can be positioned on the rail through the positioning plate 203.

[0027] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that the front end of the housing 101 is provided with a snap-fit ​​mechanism 4, which is composed of an outer frame 401, a pull-out frame 402, a snap-fit ​​frame 403 and a reset spring 404. The outer frame 401 is welded to the front end of the housing 101, the pull-out frame 402 is slidably connected to the inside of the outer frame 401, the reset spring 404 is welded between the pull-out frame 402 and the outer frame 401, and the snap-fit ​​frame 403 is rotatably connected to one side of the pull-out frame 402 through a pin shaft. When the longitudinal frame 301 rotates around the rotating shaft 305 to a horizontal state, the card frame 403 can be pulled to one side so that the longitudinal frame 301 is not blocked. At this time, the card frame 403 can be rotated to be in a vertical state with the shell 101. At this time, the pull-out frame 402 is released, so that the card frame 403 will be stuck on the outer surface of the longitudinal frame 301 under the action of the return spring 404 and position it, thereby realizing the folding of the cutting machine, making it easy to move and carry.

[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that a positioning groove 306 is provided at the front end of the first guide plate 302, and a bolt 307 extending into the positioning groove 306 is threadedly connected to the front end of the longitudinal frame 301, and the front end of the bolt 307 is connected to the front end of the longitudinal frame 301 by a connecting rope. When it is necessary to pull the cutting machine body 1 to move, the first guide plate 302 and the longitudinal frame 301 are positioned by the bolt 307 and the positioning groove 306, so that the cutting machine body 1 can be prevented from sliding downward.

[0029] The working principle of the utility model is as follows: when using the cutting machine with a protective structure, it is moved to the side of the cutting rail, and then the support frame 201 is sleeved on the rail, and the electric push rod 202 is controlled to work and extend until the positioning plate 203 is firmly fitted with the side wall of the rail, and the drive motor 102 is started at this time, so that the output end of the drive motor 102 drives the support shaft 103 and the cutting disc 104 to rotate under the action of the pulley group, and at the same time, the cutting disc 104 is gradually moved down under the action of the transverse frame 303, the first guide plate 302, the longitudinal frame 301, the second guide plate 304 and the rotating shaft 305 and cuts the rail, and in this process, the cutting disc 104 and the rail are always in a vertical state, so that the protection of the rail can be achieved, thereby preventing the occurrence of inclined cutting and making the cutting surface of the rail uneven, which is beneficial to the docking of the two rails in the later stage.
