[0002] Machine tool special steel is significantly different from ordinary steel in performance, and has higher strength and hardness, and often has more complex alloy components and organizational structures to meet the use requirements of machine tools under high-precision and high-load working conditions. Due to the above characteristics, the machine tool special steel needs to be cut by laser cutting when making machine tool accessories to cut corresponding holes, grooves and other structures in the machine tool special steel. At present, laser cutting is becoming more and more mature, and the intelligent system can control the laser cutting head to accurately control the shape and size of the cut, adapt to the machining requirements of complex structures, and reduce the machining stress and deformation to protect the mechanical properties of the material.

[0003] When the machine tool special steel is laser cut, the waste after cutting needs to be collected to ensure the safety of the operation and realize resource recycling.

[0036] Please refer to Figures 1 to 10: Embodiment one

[0037] The application provides an intelligent laser cutting device for machining machine tool special steel, which comprises a laser cutting assembly 1, the laser cutting assembly 1 comprises a displacement mechanism 101, a lifting push rod 102, a laser cutting head 103 and a waste collecting seat 104, the displacement mechanism 101 is installed on the side of the waste collecting seat 104, the lifting push rod 102 is fixedly installed on the side of a transverse moving arm of the displacement mechanism 101, the laser cutting head 103 is fixedly installed at the bottom of the lifting push rod 102, the laser cutting assembly 1 can realize laser cutting operation on the machine tool special steel, the displacement mechanism 101 can drive the lifting push rod 102 and the laser cutting head 103 at the bottom of the lifting push rod 102 to displace and position a cutting position in a plane, and the lifting push rod 102 can drive the laser cutting head 103 to vertically move up and down, so that the laser cutting head 103 can be positioned on the machine tool special steel and cutting operation and the like can be realized through intelligent control of a control device, and the device is convenient and flexible to use, and further comprising a waste collecting assembly, the waste collecting assembly comprises a switching mechanism 2 and a triggering mechanism 3.

[0038] The switching mechanism 2 comprises a channel flap 201 and two linkage seats 202, the channel flap 201 is rotationally connected in a material collecting channel of the waste collecting seat 104, the two linkage seats 202 are inserted into the waste collecting seat 104, and the two linkage seats 202 are arranged on the two sides of a rotating shaft of the channel flap 201; the triggering mechanism 3 comprises a collecting box 301, a triggering plate 302, a supporting block 303, a positioning disc 304 and a positioning rod 305, the collecting box 301 is inserted into the waste collecting seat 104, the triggering plate 302 is inserted into the collecting box 301, the supporting block 303 is inserted into the collecting box 301, the positioning disc 304 is inserted into the collecting box 301, and the positioning rod 305 is rotationally connected at the bottom of the triggering plate 302.

[0039] The triggering mechanism 3 is provided with two groups, and the two groups of triggering mechanisms 3 are symmetrically arranged on the two sides of the waste collecting seat 104, in use, waste after the machine tool special steel is cut can fall into the waste collecting assembly through the material collecting channel of the waste collecting seat 104, and the switching mechanism 2 can switch the falling direction of the waste, so that, under the alternating use of the two groups of triggering mechanisms 3, the phenomenon that the waste is overflowed and scattered into the working environment when the waste is full can be avoided.

[0040] The top side of the linkage seat 202 is provided with linkage rack 2021, and the outside of the rotating shaft of the channel flap 201 is provided with linkage gear 2011, the two linkage racks 2021 are respectively engaged with the teeth on both sides of the linkage gear 2011 to drive, the bottom of the positioning disc 304 is provided with a control top spring 3041, and the two ends of the control top spring 3041 are respectively abutted against the bottom of the positioning disc 304 and the inside of the collecting box 301. In use, the initial state of the channel flap 201 is taken as an example of left inclination, at this time, the waste can be guided by the channel flap 201 to the inside of the collecting box 301 of the left trigger mechanism 3 for temporary collection and storage after passing through the material collecting channel. When the inside of the collecting box 301 is not full of waste, the total weight of the waste on the trigger plate 302 at this time is not enough to deform and compress the control top spring 3041. The inside of the waste collecting seat 104 is provided with a raised support groove 1041. When the support block 303 is inserted into the inside of the raised support groove 1041, the collecting box 301 is in a suspended state in the inside of the waste collecting seat 104. The support block 303 can be stably inserted into the inside of the raised support groove 1041, so that the collecting box 301 can always be in a suspended state and remain stable.

[0041] The bottom of the trigger plate 302 is provided with an inclined trigger groove 3021, and the inside of the support block 303 is provided with a trigger rod 3031 which is inserted into the inside of the trigger groove 3021. In use, as the amount of waste in the collection box 301 increases, the total weight of the waste also gradually increases. When the total weight of the waste is greater than the elastic force of the control top spring 3041, the trigger plate 302 moves downward and compresses the control top spring 3041. When the trigger plate 302 moves, the trigger groove 3021 can drive the support block 303 to move towards the inside of the collection box 301 through the trigger rod 3031, so that the support block 303 is out of the inside of the heightening support groove 1041. At this time, the support block 303 fails to provide support function for the trigger mechanism 3, so that the left collection box 301 falls in the inside of the waste collection seat 104. The bottom side of the linkage seat 202 is provided with a gravity pressing plate 2022. The gravity pressing plates 2022 of the two linkage seats 202 are vertically staggered and symmetrically staggered in the plane. The gravity pressing plate 2022 of the linkage seat 202 is arranged at the bottom of the collection box 301 on the other side of the axis of the channel flap 201. When the collection box 301 falls, it can touch and press the gravity pressing plate 2022 at the bottom to move downward synchronously. When the gravity pressing plate 2022 moves downward, it can drive the linkage seat 202 to move downward. When the linkage seat 202 moves downward, the linkage rack 2021 can drive the channel flap 201 to rotate through the linkage gear 2011, so that the channel flap 201 is switched to the state of being used to incline to the right. In this process, the other linkage seat 202 moves upward so that the gravity pressing plate 2022 at the bottom touches the collection box 301 at the bottom of the right trigger mechanism 3, in order to continue to trigger the switching action (i.e. the right collection box 301 will be switched to the state of being used to incline to the left after being filled). After the left collection box 301 falls, the waste in the inside can be taken out for recycling and other operations. After the collection box 301 is emptied, it can be inserted into the inside of the heightening support groove 1041 of the waste collection seat 104, which is convenient and flexible.

[0042] The rod body of the positioning rod 305 is externally provided with threads, and the positioning rod 305 is screwed into the inside of the positioning disc 304 through the rod body threads. In use, the total weight of the waste when the trigger mechanism 3 triggers the collection box 301 to fall can be freely controlled, so as to adapt to the laser cutting of different types of machine tool special steel and the recycling of waste. When the positioning rod 305 rotates, the positioning rod 305 can drive the positioning disc 304 to move and change the use position through the rod body threads. The change of the use position of the positioning disc 304 changes the initial extension state of the control top spring 3041, that is, the total weight of the waste required to overcome the elastic force of the control top spring 3041 when the collection box 301 falls can be controlled as needed, which has strong adaptability.

[0043] The specific use and role of the embodiment are as follows: in the embodiment, the laser cutting assembly 1 can realize laser cutting operation on machine tool special steel, the displacement mechanism 101 can drive the lifting push rod 102 and the laser cutting head 103 at the bottom of the lifting push rod 102 to displace and position the cutting position in the plane, and the lifting push rod 102 can drive the laser cutting head 103 to vertically ascend and descend, so that the intelligent control of the control device can realize the positioning and cutting of the laser cutting head 103 on the machine tool special steel, and the waste after the machine tool special steel is cut can fall into the inside of the waste collecting assembly through the collecting channel of the waste collecting seat 104, and the switching mechanism 2 can switch the falling direction of the waste, so that when the waste is full, the waste can be prevented from overflowing and scattering into the working environment, and the initial state of the channel flap 201 is taken as an example, that is, the channel flap 201 is inclined to the left, and the waste can be guided by the channel flap 201 to the inside of the collecting box 301 of the left trigger mechanism 3 for temporary collection when the waste passes through the collecting channel, when the waste is not full in the collecting box 301, the total weight of the waste on the trigger plate 302 is not enough to deform and compress the control top spring 3041, and the supporting block 303 can be stably inserted into the inside of the heightening supporting groove 1041, so that the collecting box 301 can always be in a suspended state, as the waste in the collecting box 301 increases, the total weight of the waste also gradually increases, until the total weight of the waste is greater than the elastic force of the control top spring 3041, the trigger plate 302 moves downward and compresses the control top spring 3041, and when the trigger plate 302 moves, the trigger groove 3021 can drive the supporting block 303 to move into the inside of the collecting box 301 through the trigger rod 3031, so that the supporting block 303 is out of the inside of the heightening supporting groove 1041, and the supporting function of the supporting block 303 for the trigger mechanism 3 is invalid, so that the left collecting box 301 falls in the inside of the waste collecting seat 104, and the collecting box 301 can abut and extrude the gravity pressing plate 2022 at the bottom to move downward synchronously, the gravity pressing plate 2022 can drive the linkage seat 202 to move downward when the gravity pressing plate 2022 moves downward, the linkage rack 2021 can drive the channel flap 201 to rotate through the linkage gear 2011 when the linkage seat 202 moves downward, so that the channel flap 201 is switched to the state of being inclined to the right for use, and in the process, the other linkage seat 202 moves upward to abut the gravity pressing plate 2022 at the bottom of the right trigger mechanism 3, so as to continue the switching action (that is, the right collecting box 301 is full, and the channel flap 201 is switched to the state of being inclined to the left for use again), the left collecting box 301 falls out to collect the waste in the inside of the collecting box 301, and the like, and the collecting box 301 is inserted into the inside of the heightening supporting groove 1041 of the waste collecting seat 104 again after the collecting box 301 is emptied, the total weight of the waste when the collecting box 301 falls out can be freely regulated and used, so that the laser cutting of different types of machine tool special steel and the waste recycling can be adapted,When the rotating positioning rod 305 is rotated, the positioning rod 305 can drive the positioning disc 304 to move through the rod body thread to change the use position. The change of the use position of the positioning disc 304 changes the initial extension state of the control top spring 3041, that is, the total weight value of the waste required to be overcome by the control top spring 3041 when the collection box 301 falls is changed, and the use can be controlled as required.

[0044] In another embodiment, the side surface of the channel flap 201 is provided with an elastic pin column, and the outer end of the elastic pin column is semispherical. The elastic pin column is inserted into the positioning groove in the interior of the waste collection seat 104, can keep the use state of the channel flap 201 when guiding the waste, avoids the phenomenon of accidental rotation or overturning of the channel flap 201, and when the switching action of the waste collection assembly is triggered, since the total weight of the waste is greater than the elastic force of the elastic pin column, the elastic pin column does not hinder and affect the switching action of the waste collection assembly, and the stability of the device is further improved.
