The quick return motion assembly is located between the right sliding groove and the left sliding groove. The driving motor is connected to the quick return motion assembly. The two cutting members are respectively connected to both sides of the quick return motion assembly. The stroke speed ratio coefficient of the quick return motion assembly is greater than 1, so that the quick return motion assembly has a first state of approaching thick rails at a first speed and a second state of approaching thin rails at a second speed during its movement, and the first speed is less than the second speed.

[0006] In one embodiment, the quick return motion assembly includes a first gear, a second gear, a first transmission rod and a second transmission rod. The first gear is connected to the driving motor. The first gear meshes with the second gear. A convex block is provided at a non - center position on the surface of the second gear.

The movement of the trigger rod following the second transmission rod can drive the ball valve to rotate, thereby adjusting the on-off of the communication relationship between the coolant pipe and the receiving space. The coolant pipe extends from the communication box to the left chute.

[0008] In one embodiment, the liquid outlet assembly further includes a lubricating oil pipe. The lubricating oil pipe is arranged on one side of the communication box close to the thick rail. The lubricating oil pipe extends from one side of the communication box to one side of the right chute.

[0009] When the quick return motion assembly is in the first state, it can drive the trigger rod to rotate clockwise and drive the ball valve to rotate clockwise to connect the ball valve with the lubricating oil pipe and disconnect it from the coolant pipe.

[0010] When the quick return motion assembly is in the second state, it can drive the trigger rod to rotate counterclockwise and drive the ball valve to rotate counterclockwise to connect the ball valve with the coolant pipe and disconnect it from the lubricating oil pipe.

[0011] In one embodiment, the rail carrier is provided with two notches. The orthographic projection of the notches towards the bottom surface of the rail carrier is the first projection, and the orthographic projection of the cutting member towards the bottom surface of the rail carrier is the second projection. The second projection is located within the area of the first projection, so that lubricating oil or coolant can flow out from the notches.

[0012] In one embodiment, a second convex block is provided on the ball valve, and a second sliding groove is formed on the trigger rod. The second convex block extends into the second sliding groove and is fixedly connected to the inner wall of the second sliding groove.

[0014] In one embodiment, the lubricating oil pipe includes a main lubricating pipe, a first sub-lubricating pipe, and a second sub-lubricating pipe. The main lubricating pipe is in communication with the accommodating space. The first sub-lubricating pipe and the second sub-lubricating pipe respectively extend from one end of the main lubricating pipe away from the communication box to the cutting position of the thick rail.

[0033] The following combination Figures 1-3 shown will further explain and illustrate a cutting device for rail production related to the present utility model.

[0034] In an embodiment of a cutting device for rail production, the cutting device for rail production includes a rail carrier 1, a driving motor 2, a quick-return motion assembly 3, and two cutting members 4. The rail carrier 1 is provided with a right chute 11 and a left chute 12. The thick rail 200 slides on the right chute 11, and the thin rail 100 slides on the left chute 12. The driving motor 2 and the quick-return motion assembly 3 are both installed on the rail carrier 1. The quick-return motion assembly 3 is located between the right chute 11 and the left chute 12. The driving motor 2 is connected to the quick-return motion assembly 3. The two cutting members 4 are respectively connected to both sides of the quick-return motion assembly 3. The stroke speed ratio coefficient of the quick-return motion assembly 3 is greater than 1, so that the quick-return motion assembly 3 has a first state of approaching the thick rail 200 at a first speed and a second state of approaching the thin rail 100 at a second speed during its movement, and the first speed is less than the second speed. Specifically, the driving motor 2 is electrically connected to the quick-return motion assembly 3, and the cutting member 4 is a milling cutter.

[0035] In this embodiment, under the action of the driving motor, the quick-return motion assembly can reciprocate, and the stroke speed ratio coefficient of the quick-return motion assembly is greater than 1. In this way, when the thick and thin rails are cut simultaneously by the quick-return motion assembly, the cutting speed can be adjusted by the quick-return motion assembly, so that the speed is slower when cutting the thick rail and faster when cutting the thin rail, improving the cutting efficiency and ensuring the cutting quality.

[0036] Preferably, the extending direction of the right chute 11 is parallel to the extending direction of the left chute 12.

[0037] In one embodiment, the quick-return motion assembly 3 includes a first gear 31, a second gear 32, a first transmission rod 33, and a second transmission rod 34. The first gear 31 is connected to the driving motor 2. The first gear 31 meshes with the second gear 32. A convex block 35 is provided at a non-central position on the surface of the second gear 32. One end of the first transmission rod 33 is rotatably connected to the rail carrier 1, and the other end is rotatably connected to the second transmission rod 34 through a shaft. A first sliding groove 331 is provided on the first transmission rod 33, and the convex block 35 extends into the first sliding groove 331 to be able to drive the first transmission rod 33 to swing reciprocally. The first transmission rod 33 and the second transmission rod 34 form a 90° angle, and the two cutting members 4 are respectively installed at both ends of the second transmission rod 34.

[0038] In this embodiment, the driving motor 2 drives the first gear 31 to rotate. The rotation of the first gear 31 can drive the second gear 32 to rotate, and the first transmission rod 33 follows the movement of the second gear 32, so that the first transmission rod 33 can drive the second transmission rod 34 to reciprocate along a first direction. Specifically, the first direction is perpendicular to the extending direction of the rail, and the first gear 31 is electrically connected to the driving motor 2.

[0039] In one embodiment, the cutting device for rail production further includes a liquid outlet assembly 5. The liquid outlet assembly 5 includes a trigger rod 51, a ball valve 52, a communication box 53, and a coolant pipe 54. A receiving space 55 is provided in the communication box 53. The coolant pipe 54 is communicated with the receiving space 55. The ball valve 52 is arranged in the receiving space 55 and is rotatably connected to the trigger rod 51 through a rotating shaft. The trigger rod 51 is also rotatably connected to the second transmission rod 34. The movement of the trigger rod 51 following the second transmission rod 34 can drive the ball valve 52 to rotate, thereby adjusting the on-off of the communication relationship between the coolant pipe 54 and the receiving space 55. The coolant pipe 54 extends from the communication box 53 to the left chute 12.

[0040] In this embodiment, by providing the coolant pipe 54, during the cutting process, the driving motor 2 drives the quick return motion assembly 3 to perform a reciprocating motion in the first direction. The quick return motion assembly 3 pulls the ball valve 52 to rotate and thus communicate with the coolant pipe 54, and the coolant flows out, preventing the problem of rough cutting surface due to too high temperature at the cutting position during the cutting of thin rails, and improving the cutting quality.

[0041] In one embodiment, the liquid outlet assembly 5 further includes a lubricating oil pipe 56. The lubricating oil pipe 56 is arranged on the side of the communication box 53 close to the thick rail 200. The lubricating oil pipe 56 extends from one side of the communication box 53 to one side of the right chute 11. When the quick return motion assembly 3 is in the first state, it can drive the trigger rod 51 to rotate clockwise and drive the ball valve 52 to rotate clockwise to connect the ball valve 52 with the lubricating oil pipe 56 and disconnect it from the coolant pipe 54. When the quick return motion assembly 3 is in the second state, it can drive the trigger rod 51 to rotate counterclockwise and drive the ball valve 52 to rotate counterclockwise to connect the ball valve 52 with the coolant pipe 54 and disconnect it from the lubricating oil pipe 56.

[0042] It can be understood that when cutting the thick rail 200, the quick return motion assembly 3 is in the first state. The quick return motion assembly 3 pulls the ball valve 52, so that the liquid outlet assembly 5 is switched to the state where the lubricating oil pipe 56 is connected and the coolant pipe 54 is disconnected, and the cutting position of the thick rail 200 can be lubricated by the lubricating oil, reducing the friction and resistance during the cutting of the thick rail, improving the cutting efficiency and reducing the tool wear. When cutting the thin rail 100, the quick return motion assembly 3 is in the second state, and the coolant pipe 54 is connected. The cutting position of the thin rail 100 is quickly cooled by the coolant, preventing the thin rail 100 from deforming or being damaged due to too high temperature, ensuring the cutting quality, and meeting the cooling and lubrication requirements of different thickness rails during cutting.

[0043] In one embodiment, the rail carrier 1 is provided with two notches 13. The positive projection of the notch 13 towards the bottom surface of the rail carrier 1 is the first projection, and the positive projection of the cutting member 4 towards the bottom surface of the rail carrier 1 is the second projection. The second projection is located within the area of the first projection, so that the lubricating oil or coolant can flow out from the notch 13.

[0044] In this embodiment, after the lubricating oil or coolant completes the cooling and lubrication at the cutting position, it can smoothly drain from the notch 13, preventing the liquid from accumulating on the track carrier 1 and avoiding the influence of liquid residue on the next cutting.

[0045] In addition, it should be explained that the orthographic projection towards the bottom surface of the track carrier 1 is the projection along the vertical direction.

[0046] In one embodiment, a second convex block 521 is provided on the ball valve 52, and a second sliding groove 511 is formed on the trigger rod 51. The second convex block 521 extends into the second sliding groove 511 and is fixedly connected to the inner wall of the second sliding groove 511. The trigger rod 51 can drive the ball valve 52 to rotate, thereby realizing the switching between the lubricating oil pipe 56 and the coolant pipe 54, and providing a suitable cooling medium for cutting rails of different thicknesses.

[0047] In one embodiment, the coolant pipe 54 includes a cooling main pipe 541, a first cooling branch pipe 542, and a second cooling branch pipe 543. The cooling main pipe 541 is communicated with the accommodating space 55. One end of the first cooling branch pipe 542 and one end of the second cooling branch pipe 543 are both communicated with the cooling main pipe 541, and the other ends both extend to the cutting position of the thin rail 100. The first cooling branch pipe 542 corresponds to the position below the thin rail 100, and the second cooling branch pipe 543 corresponds to the position above the thin rail 100.

[0048] In this embodiment, the first cooling branch pipe 542 and the second cooling branch pipe 543 respectively correspond to the cutting positions below and above the thin rail 100, achieving sufficient cooling of the cutting position of the thin rail 100, ensuring that the coolant can fully act on the cutting position, and improving the cooling effect.

[0049] In one embodiment, the lubricating oil pipe 56 includes a lubricating main pipe 561, a first lubricating branch pipe 562, and a second lubricating branch pipe 563. The lubricating main pipe 561 is communicated with the accommodating space 55. The first lubricating branch pipe 562 and the second lubricating branch pipe 563 respectively extend from one end of the lubricating main pipe 561 away from the communication box 53 to the cutting position of the thick rail 200, and the first lubricating branch pipe 562 and the second lubricating branch pipe 563 are respectively communicated with the lubricating main pipe 561. The first lubricating branch pipe 562 corresponds to the position below the thick rail 200, and the second lubricating branch pipe 563 corresponds to the position above the thick rail 200.

[0050] In this embodiment, the first lubricating branch pipe 562 and the second lubricating branch pipe 563 respectively correspond to the cutting positions below and above the thick rail 200, achieving sufficient cooling of the cutting position of the thick rail 200, ensuring that the coolant can fully act on the cutting position, and improving the cooling effect.

[0051] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0052] The above embodiments only express several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
