Description

Technical Field

[0001] The present invention relates to the field of laser cutting technology, and in particular to an intelligent laser cutting device for processing special steel for machine tools. Background Art

[0002] Special steel for machine tools differs significantly from ordinary steel in performance. It has higher strength and hardness, and often has more complex alloy composition and organizational structure to meet the use requirements of machine tools under high-precision and high-load conditions. Due to the above characteristics, special steel for machine tools needs to be laser cut when making machine tool accessories to achieve cutting of corresponding holes, grooves and other structures inside it. At present, laser cutting is becoming more and more mature. The laser cutting head is controlled by an intelligent system, which can accurately control the shape and size of the incision to adapt to its complex structural processing needs, while reducing processing stress and deformation and ensuring the mechanical properties of the material.

[0003] When laser cutting is performed on special steel for machine tools, the waste after cutting needs to be collected to ensure operation safety and achieve resource recycling. For example, the patent with application number: CN202220695344.9 discloses a waste collection device for a steel plate laser cutting machine, which includes a recovery base, a recovery box body is provided on the top of the recovery base, a feeding port is opened on the top of the recovery box body, and a first motor is provided on the outer wall of the recovery box body. One end of the output shaft of the first motor passes through the interior of the recovery box body and is transmission-connected to the first gear. Two second gears are provided at the bottom of the inner wall of the recovery box body at the bottom of the first gear. The outer surfaces of the two second gears are both provided with crushing rollers. A second motor is provided at the bottom end of the inner part of the recovery base. The top end of the output shaft of the second motor is transmission-connected to a filter screen 1 through a coupling. Cleaning boxes are provided on both sides of the recovery box body, and a water collecting tank is provided at the bottom end of the cleaning box. The scraps generated by cutting are first crushed by the crushing rollers and then fall onto the upper surface of the filter screen 1. The crushed waste is convenient for subsequent melting processing and can be reused.

[0004] When the existing laser cutting device for special steel processing of machine tools is in operation, the waste generated by cutting usually falls directly into a manually placed collection box. The operator needs to regularly check the waste accumulation in the collection box. When the waste is close to the upper limit of the collection box capacity, the collection box needs to be taken out in time for waste cleaning and recycling. If the waste is not cleaned in time, the waste will overflow the collection box and scatter into the working environment, which not only increases the workload of subsequent secondary collection and cleaning of waste, but may also affect the cleanliness of the work site and the safety of equipment operation. It has poor flexibility and low practicality. Summary of the Invention

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Please refer to Figures 1 to 10 :Example 1: The present invention proposes an intelligent laser cutting device for processing special steel for machine tools, comprising: a laser cutting assembly 1, the laser cutting assembly 1 comprising a displacement mechanism 101, a lifting push rod 102, a laser cutting head 103 and a waste collection seat 104, the displacement mechanism 101 is mounted on the side of the waste collection seat 104, and the lifting push rod 102 is fixedly mounted on the side of the transverse moving arm of the displacement mechanism 101, and the laser cutting head 103 is fixedly mounted on the bottom of the lifting push rod 102, the laser cutting assembly 1 can realize the laser cutting operation of special steel for machine tools, the displacement mechanism 101 can drive the lifting push rod 102 and the laser cutting head 103 at the bottom thereof to displace and locate the cutting position in the plane, and the lifting push rod 102 can drive the laser cutting head 103 to move vertically, so that through the intelligent control of the control device, the laser cutting head 103 can realize the positioning and cutting operations on the special steel for machine tools, and the use is convenient and flexible; it also includes a waste collection assembly, which is composed of a switching mechanism 2 and a trigger mechanism 3; The switching mechanism 2 includes a channel flap 201 and two linkage seats 202. The channel flap 201 is rotatably connected to the collection channel of the waste collection seat 104, and the two linkage seats 202 are inserted into the interior of the waste collection seat 104. The two linkage seats 202 are respectively arranged on both sides of the rotating shaft of the channel flap 201; the trigger mechanism 3 includes a collection box 301, a trigger plate 302, a support block 303, a positioning disk 304 and a positioning rod 305. The collection box 301 is inserted into the interior of the waste collection seat 104, and the trigger plate 302 is inserted into the interior of the collection box 301, the support block 303 is inserted into the interior of the collection box 301, the positioning disk 304 is inserted into the outside of the positioning rod 305, and the positioning disk 304 is inserted into the interior of the collection box 301, and the positioning rod 305 is rotatably connected to the bottom of the trigger plate 302.

[0031] Among them, there are two groups of trigger mechanisms 3, and the two groups of trigger mechanisms 3 are symmetrically arranged on both sides of the waste collection seat 104. During use, the waste after cutting the machine tool special steel can fall into the interior of the waste collection component through the collection channel of the waste collection seat 104, and the switching mechanism 2 can switch the falling direction of the waste, so that when the two groups of trigger mechanisms 3 are used alternately, it can avoid the phenomenon of waste overflowing and scattering into the working environment when the waste is full.

[0032] Among them, a linkage rack 2021 is provided on the top side of the linkage seat 202, and a linkage gear 2011 is provided on the outside of the rotating shaft of the channel flap 201. The two linkage racks 2021 are respectively engaged with the gear teeth on both sides of the linkage gear 2011 for transmission. A control top spring 3041 is provided at the bottom of the positioning plate 304, and the two ends of the control top spring 3041 are respectively against the bottom of the positioning plate 304 and the inside of the collection box 301. In use, the initial state of the channel flap 201 is tilted to the left for example. At this time, the waste can be guided to the left by the channel flap 201 after passing through the collection channel. The collection box 301 of the trigger mechanism 3 is used for temporary storage. When the collection box 301 is not full of waste, the total weight of the waste on the trigger plate 302 is not enough to cause the control top spring 3041 to deform and compress. The waste collection seat 104 is provided with a raised support groove 1041. When the support block 303 is inserted into the raised support groove 1041, the collection box 301 is in a suspended state inside the waste collection seat 104. The support block 303 can be stably inserted into the raised support groove 1041, so that the collection box 301 can always be in a suspended state and remain stable.

[0033] The bottom of the trigger plate 302 is provided with an inclined trigger groove 3021, and the interior of the support block 303 is provided with a trigger rod 3031, which is inserted into the interior of the trigger groove 3021. During use, as the amount of waste in the collection box 301 increases, the total weight of the waste will gradually increase until the total weight of the waste exceeds the elastic force of the control top spring 3041. The trigger plate 302 will move downward and compress the control top spring 3041. When the trigger plate 302 moves, the trigger groove 3021 can be pulled by the trigger rod 3031. The movable support block 303 moves toward the inside of the collection box 301, so that the support block 303 escapes from the inside of the raised support groove 1041. At this time, the support function provided by the support block 303 to the trigger mechanism 3 fails, so that the collection box 301 on the left side will fall inside the waste collection seat 104. The bottom side of the linkage seat 202 is provided with a gravity pressure plate 2022. The gravity pressure plates 2022 of the two linkage seats 202 are staggered up and down in the vertical direction, and the gravity pressure plates 2022 of the two linkage seats 202 are staggered and symmetrical in the plane. The gravity pressure plate 2022 of the seat 202 is set 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 resist and squeeze the gravity pressure plate 2022 at its bottom to move downward synchronously. When the gravity pressure 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 a state of rightward tilt. In this process, The other linkage seat 202 will move up so that the gravity pressure plate 2022 at its bottom will contact the bottom of the collection box 301 of the right trigger mechanism 3, so as to prepare for the subsequent triggering of the switching action (that is, after the right collection box 301 is full, the channel flap 201 will be switched to a left-tilted state again). After the collection box 301 on the left falls, it can be pulled out for recycling and other operations. After the collection box 301 is emptied, it can be reinserted into the raised support groove 1041 of the waste collection seat 104. It is easy to operate and flexible.

[0034] Among them, the outside of the rod body of the positioning rod 305 is provided with a thread, and the positioning rod 305 is screwed to the inside of the positioning plate 304 through the rod body thread. In use, the total weight value of the waste when the trigger mechanism 3 triggers the collection box 301 to fall can be freely adjusted and used, so that it can adapt to the laser cutting processing of different types of machine tool special steel and waste recycling. When the positioning rod 305 is rotated, the positioning rod 305 can drive the positioning plate 304 to move and change the use position through the rod body thread. The change of the use position of the positioning plate 304 changes the initial extension and contraction state of the control top spring 3041, that is, the total weight value of the waste required to overcome the elastic force of the control top spring 3041 when the collection box 301 is triggered to fall. It can be adjusted and used as needed and has strong adaptability.

[0035] The specific usage and function of this embodiment: In the present invention, the laser cutting assembly 1 can realize the laser cutting operation of machine tool special steel, the displacement mechanism 101 can drive the lifting push rod 102 and the laser cutting head 103 at the bottom to displace and locate the cutting position in the plane, and the lifting push rod 102 can drive the laser cutting head 103 to move up and down longitudinally, so that through the intelligent control of the control device, the laser cutting head 103 can realize positioning and cutting operations on machine tool special steel, and the waste after cutting of the machine tool special steel can fall into the interior of the waste collection assembly through the collection channel of the waste collection seat 104, and the switching mechanism 2 can switch the falling direction of the waste, so that when the two sets of trigger mechanisms 3 are used alternately, it can be avoided that the waste is overflowed and scattered when it is full. The phenomenon occurs in the working environment. Here, the initial state of the channel flap 201 is tilted to the left as an example. At this time, after the waste passes through the collection channel, it can be guided by the channel flap 201 to the inside of the collection box 301 of the left trigger mechanism 3 for collection and temporary storage. When the collection box 301 is not full of waste, the total weight of the waste on the trigger plate 302 is not enough to cause the control top spring 3041 to deform and compress. The support block 303 can be stably inserted into the inside of the raised support groove 1041, so that the collection box 301 can always be in a suspended state. As the amount of waste in the collection box 301 increases, the total weight of the waste will gradually increase. Until the total weight of the waste is greater than the elastic force of the control top spring 3041, the trigger plate 302 will move downward and compress After the jacking is complete, the jacking mechanism 310 is turned off, and the jacking mechanism 310 is turned off, so that the jacking mechanism 310 is turned off, and the jacking mechanism 310 is turned off, so that the jacking mechanism 310 is turned off, and the jacking mechanism 310 is turned off, so that the jacking mechanism 310 is turned off, and the jacking mechanism 310 is turned off, so that the jacking mechanism 310 is turned off, and the jacking mechanism 310 is turned off, so that the jacking mechanism 310 is turned off, 1 is switched to a state of rightward tilting use, and in this process, the other linkage seat 202 moves up to make the gravity pressure plate 2022 at its bottom contact the bottom of the collection box 301 of the right trigger mechanism 3, so as to prepare for the subsequent triggering switching action (that is, when the right collection box 301 is full, the channel flap 201 will be switched to a state of leftward tilting use again). After the collection box 301 on the left falls, it can be pulled out for recycling and other operations. After the collection box 301 is emptied, it can be reinserted into the raised support groove 1041 of the waste collection seat 104. The total weight value of the waste when the trigger mechanism 3 triggers the collection box 301 to fall can be freely adjusted and used, so that it can adapt to the laser cutting processing and waste recycling of different types of machine tool special steel.When the positioning rod 305 is rotated, the positioning rod 305 can drive the positioning plate 304 to move and change its use position through the rod body thread. The change in the use position of the positioning plate 304 changes the initial expansion and contraction 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 triggering the collection box 301 to fall. This can be adjusted as needed.

[0036] In another embodiment, an elastic pin is provided on the side of the channel flap 201, and the outer end of the elastic pin is semi-spherical. By inserting the elastic pin into the positioning groove inside the waste collection seat 104, the channel flap 201 can be kept in the use state when guiding the waste, avoiding the channel flap 201 from accidentally rotating or flipping. When the switching action of the waste collection component is triggered, since the total weight of the waste is greater than the elastic force of the elastic pin, the elastic pin will not hinder and affect the switching action of the waste collection component, thereby further improving the stability of the device.
