Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to laser cutting equipment for worm production with a smoke and dust collection function. Background Art

[0002] In the production process of worm gears, the first step is to cut the rod-shaped raw materials to a preset length, and then transport the cut blanks to processing equipment such as milling machines for tooth processing. As laser cutting technology has significant advantages such as high precision, high efficiency and non-contact processing, especially in the cutting application of small-diameter rods, more and more factories are currently using laser cutting equipment in the front-end blanking process of worm gear production.

[0003] The working principle of laser cutting technology is to locally heat the material through a high-energy-density laser beam, causing it to melt or vaporize rapidly, thereby achieving cutting. However, during the laser cutting process, a large amount of smoke, debris and sparks will inevitably be generated. These byproducts will not only pollute the environment, but may also harm the health of the operator. Existing laser cutting equipment is usually equipped with an air suction device to collect and treat the smoke generated during the cutting process. However, the current air suction device often needs to generate a large suction force to effectively collect smoke during use, but excessive suction will not only increase energy consumption, but may also form strong airflow disturbances in the cutting area, interfere with the stability of the laser beam, and thus affect the cutting effect; finally, during the cutting process, the existing laser cutting equipment is difficult to ensure the position stability of the raw materials. When the raw materials jump due to the rotation speed or the wear of the machine tool spindle, the relative position between the raw materials and the laser cutting head will change, which will cause the laser focus position to be unstable, affecting the incision quality. Summary of the invention

[0004] The purpose of the present invention is to provide a laser cutting device for worm production with a smoke and dust collection function to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a laser cutting device for worm production with a smoke and dust collection function, the laser cutting device comprising a body, a chuck and a linear motor are installed on the body, the chuck clamps and fixes the material and drives the material to rotate, a mounting frame is arranged on the linear motor, a first mounting seat is arranged at one end of the mounting frame close to the chuck, a lifting module and a waste recovery component are arranged inside the first mounting seat, a laser cutting head is arranged below the lifting module, the laser cutting head and the lifting module are connected by a connecting seat, a working frame is arranged below the laser cutting head, and a group of sealing components are arranged at both ends of the working frame. The working frame is connected with the smoke collection mechanism through the exhaust pipe. During the cutting operation, the material passes through the working frame and is concentric with the working frame. The two ends of the working frame are isolated from the external environment through two sets of sealing components. Then, the laser cutting head is driven downward by the lifting module to extend into the working frame, and the material is cut by the laser cutting head. Compared with the current laser cutting equipment, the present invention can avoid the debris and sparks carried in the protective gas during laser cutting from splashing everywhere on the one hand, and can effectively prevent the interference of external airflow on the other hand to ensure the stability of the cutting process. Finally, the smoke generated during the cutting process can be collected and processed in time through the smoke collection mechanism to prevent the smoke from spreading, so as to improve the smoke collection efficiency.

[0006] Furthermore, a fixed sleeve is provided at one end of the working frame close to the laser cutting head, a movable sleeve is provided inside the fixed sleeve, the fixed sleeve and the movable sleeve are connected by a compression spring, a piezoelectric sheet is provided at one end of the movable sleeve close to the compression spring, the inner diameter of the movable sleeve is larger than the diameter of the laser cutting head and smaller than the diameter of the connecting seat, when the laser cutting head in the present invention moves down to the target position in the working frame, the connecting seat on the laser cutting head will first contact with the upper end surface of the movable sleeve, when the laser cutting head continues to move down, the connecting seat will drive the movable sleeve to move down synchronously, at this time the compression spring will deform, and the piezoelectric sheet provided at one end of the movable sleeve close to the compression spring will generate a group of electrical signals, by monitoring the changes in the electrical signals generated by the piezoelectric sheet, the staff can timely know the position of the laser cutting head to avoid collision between the material and the laser cutting head, finally, when the laser cutting head cuts the material, since the connecting seat contacts the upper end surface of the movable sleeve, the entire cutting environment will be in a completely sealed state, at this time the smoke and dust collection mechanism can completely collect the smoke and dust generated during the cutting process without generating a large suction force, thereby preventing the smoke and dust from overflowing.

[0007] Furthermore, the sealing component includes a sealing seat, an airbag is provided at the inner diameter of the sealing seat, an air cavity is provided inside the sealing seat, the air cavity is connected to the airbag, an electromagnet is provided at the end of the air cavity away from the airbag, a sealing plate is provided on the side of the electromagnet close to the airbag, compressed gas is provided on the side of the sealing plate away from the electromagnet, the sealing plate is movably installed in the air cavity through a telescopic spring rod, and a permanent magnet is embedded at the end of the sealing plate close to the electromagnet. When the sealing component of the present invention is not working, the sealing plate is close to the electromagnet. When the sealing component is in working state, the electromagnet will generate a set of magnetic fields that repel the sealing plate. The sealing plate will move away from the electromagnet and squeeze the compressed gas in the air cavity. When the compressed gas enters the airbag, the airbag will expand and wrap the material, and the two ends of the working frame will be separated from the external environment by the airbag. Compared with the current sealing components, the present invention can be applicable to materials of different diameters. At the same time, when the material rotates in the airbag, the surface of the material will not be damaged. Finally, when power outages or equipment failures occur, the airbag in the present invention will automatically loosen the material. At this time, the smoke and dust remaining in the working frame will automatically dissipate into the external environment to avoid the smoke and dust remaining in the working frame being absorbed by the staff when they are taking materials or repairing equipment.

[0008] Furthermore, a third mounting seat is provided at one end of the mounting frame away from the chuck, a second mounting seat is provided between the first mounting seat and the third mounting seat, a material collecting cover is provided below the third mounting seat, and a positioning mechanism is provided at one end below the second mounting seat close to the chuck.

[0009] Furthermore, the positioning mechanism includes a fixed frame and a rotating ring, the fixed frame is provided with two groups, the two groups of fixed frames are arranged on both sides of the rotating ring, each group of fixed frames is fixedly installed below the second mounting seat, and each group of fixed frames is provided with a group of slide grooves at one end close to the rotating ring, a clamping assembly is provided inside the rotating ring, and a group of sliders are provided at both ends of the rotating ring, and the sliders are adapted to the slide grooves. When the material is laser cut, the clamping assembly clamps the end of the material to be cut (the function realized by the clamping assembly belongs to the conventional technical means in this field, and the specific structure is not described). When the chuck drives the material to rotate, the material will drive the clamping assembly and the rotating ring to rotate synchronously. Since the rotating ring is slidably connected to the two groups of fixed frames, and the two groups of fixed frames are fixedly installed below the second mounting seat, the clamping assembly can suppress the material from jumping when clamping the material, avoid the instability of the laser focus position, and thus affect the incision quality, and at the same time prevent the material from colliding with the laser cutting head during the cutting process.

[0010] Furthermore, a transmission gear and a rotating motor are arranged inside the second mounting seat, and the working end of the rotating motor is connected to the transmission gear. An external gear is arranged outside the rotating ring, and the external gear is meshed with the transmission gear. A fixed seat is arranged on the working frame, and a first cylinder and a grinding assembly are arranged inside the fixed seat, and the working end of the first cylinder is connected to the grinding assembly.

[0011] Furthermore, the grinding assembly includes a movable seat, a grinding motor and a grinding wheel, the grinding motor is arranged inside the movable seat, the grinding wheel is arranged at one end of the movable seat close to the center line of the work frame, and the grinding motor and the grinding wheel are connected through a belt drive assembly.

[0012] When the present invention performs laser cutting on a material, the grinding assembly is moved away from the material through the first cylinder, the material is clamped through the chuck, and one end of the material to be cut is clamped through the clamping assembly. After one end of the material to be cut is cut, the staff can close the clamping assembly and the chuck, and then manually or mechanically move the cut material to the position of the collecting cover for a distance, and at the same time move the material to be cut to a position away from the second mounting seat for a distance until the end face of the cut material and the end face of the material to be cut are aligned with the two end faces of the grinding wheel. Then the staff can turn on the clamping assembly, the rotating motor and the chuck, clamp the cut material through the clamping assembly, drive the cut material to rotate through the rotating motor and the transmission gear, clamp the material to be cut through the chuck and rotate the material 3 to be cut. Finally, the grinding assembly is brought close to the material through the first cylinder, the grinding wheel is driven to rotate through the grinding motor and the belt drive assembly, and the end faces of the cut material and the end faces of the material to be cut are ground through the two ends of the grinding wheel to eliminate slag existing in the laser cutting part of the material.

[0013] Furthermore, the smoke collection mechanism includes a filter chamber and a fan, a filter assembly is arranged in the filter chamber, the air inlet end of the fan is connected to the exhaust pipe through an exhaust channel, the air outlet end of the fan is connected to the filter chamber, and an air outlet channel is arranged at one end of the filter chamber away from the fan.

[0014] Furthermore, a flow detection element is arranged above the air outlet channel, and the filter assembly includes a filter frame and a reversing motor. The reversing motor is arranged at the side end of the filter cavity and connected to the filter frame. Three groups of through holes are arranged on the filter frame, and a group of filter screens are arranged in each group of through holes. The flow detection element is electrically connected to the reversing motor.

[0015] When the present invention is cutting and grinding materials, the fan will continuously generate a set of suction forces to transport smoke and various debris into the filter chamber, and a set of filter screens near the air outlet of the fan will intercept particles and various debris in the smoke, and the wind speed of the air outlet channel will be monitored by a flow detection element. When a set of filter screens near the air outlet of the fan is blocked, the wind speed of the air outlet channel will decrease accordingly. At this time, the staff can start the reversing motor and drive the filter frame to rotate through the reversing motor to replace a set of filter screens near the air outlet of the fan. Compared with the filter components currently used in laser cutting equipment, the present invention can automatically replace the filter screens without stopping the machine to ensure work efficiency.

[0016] Furthermore, the smoke and dust collection mechanism also includes a waste channel, which is connected to the filter chamber, a baffle is provided inside the waste channel, and a second cylinder is provided at the side end of the baffle. When the present invention is working normally, the three groups of through holes on the filter frame are respectively aligned with the air outlet end, the air outlet channel, and the waste channel of the fan, and the baffle is located in the waste channel, and the waste channel is separated from the environment outside by the baffle. When the staff needs to clean a group of filters, the filter frame can be driven to rotate by the reversing motor until the filter to be cleaned is aligned with the waste channel, and then the outlet end of the waste channel is aligned with the outside The outside waste recycling system is connected to the outside world, and the baffle is kept away from the waste channel by the second cylinder. At this time, the staff only needs to turn on the fan and close the air outlet end of the flow detection element to allow the outside air to flow along the exhaust channel, the filter frame, and the waste channel. During the flow of the outside air, the smoke particles and various debris on the filter screen to be cleaned will enter the outside waste recycling system with the outside air. Through the above technical scheme, the present invention can collect smoke and grinding debris through the fan on the one hand, and can also clean the filter assembly through the fan on the other hand, so as to reduce the labor intensity of the staff.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: compared with the current laser cutting equipment, the present invention is provided with a working frame and a smoke collection mechanism, and the smoke generated during the cutting process is collected and processed by the smoke collection mechanism, and sealing components are provided at both ends of the working frame, and a fixed sleeve and a movable sleeve are provided at the upper end of the working frame. Through the cooperation of the two sets of sealing components and the fixed sleeve and the movable sleeve, the present invention can keep the entire cutting environment in a completely sealed state when laser cutting the material, on the one hand, it can avoid the debris and sparks carried in the protective gas during laser cutting from splashing everywhere, and on the other hand, the smoke collection mechanism can completely collect the smoke generated during the cutting process without generating a large suction force, thereby preventing the smoke from overflowing. In addition, the sealing component in the present invention can be suitable for materials of different diameters on the one hand. At the same time, when the material rotates in the airbag, the surface of the material will not be damaged. When a power outage or equipment failure occurs, the smoke and dust remaining in the work frame will automatically dissipate into the external environment to avoid the smoke and dust remaining in the work frame being absorbed by the staff when they are taking materials or repairing the equipment. Finally, the present invention is also provided with a positioning mechanism and a grinding assembly. The positioning mechanism can suppress the material from jumping, avoid the instability of the laser focus position, and thus affect the incision quality. At the same time, it can also prevent the material from colliding with the laser cutting head during the cutting process. Through the mutual cooperation of the positioning mechanism and the grinding assembly, the present invention can grind the cut material end face and the material end face to be cut after the laser cutting of the material is completed, so as to eliminate the slag and other phenomena existing in the laser cutting part of the material.

The two ends of the working frame 42 are isolated from the external environment through two sets of sealing components. Then, the laser cutting head 41 is driven downward by the lifting module 49 to extend into the working frame 42. The material 3 is cut by the laser cutting head 41. Compared with the current laser cutting equipment, the present invention can avoid the debris and sparks carried in the protective gas during laser cutting from splashing everywhere on the one hand, and on the other hand, it can effectively prevent the interference of external airflow to ensure the stability of the cutting process. Finally, the smoke generated during the cutting process can be collected and processed in time through the smoke collection mechanism to prevent the smoke from spreading, so as to improve the smoke collection efficiency.

The sleeve 4211 moves downward synchronously, and the compression spring will be deformed at this time. The piezoelectric sheet arranged near one end of the compression spring of the movable sleeve 4211 will generate a group of electrical signals.

Compared with the current sealing components, the present invention can be applied to materials 3 of different diameters. At the same time, when the material 3 rotates in the airbag 4234, the surface of the material 3 will not be damaged. Finally, when power outages or equipment failures occur, the airbag 4234 in the present invention will automatically loosen the material 3. At this time, the smoke and dust remaining in the working frame 42 will automatically dissipate into the external environment, so as to avoid the smoke and dust remaining in the working frame 42 being absorbed by the staff when they are taking the material 3 or repairing the equipment.

[0024] like Figure 2 and Fig. 9 As shown, a third mounting seat 6 is provided at one end of the mounting frame 12 away from the chuck 2, a second mounting seat 5 is provided between the first mounting seat 4 and the third mounting seat 6, a material collecting cover 61 is provided below the third mounting seat 6, and a positioning mechanism is provided at one end below the second mounting seat 5 close to the chuck 2.

[0025] like Figure 2 and Fig. 9 As shown, the positioning mechanism includes a fixed frame 51 and a rotating ring 52. The fixed frame 51 is provided with two groups. The two groups of fixed frames 51 are arranged on both sides of the rotating ring 52. Each group of fixed frames 51 is fixedly installed below the second mounting seat 5. Each group of fixed frames 51 is provided with a group of slide grooves at one end close to the rotating ring 52. A clamping assembly is provided inside the rotating ring 52. A group of sliders are provided at both ends of the rotating ring 52, and the sliders are adapted to the slide grooves.

[0026] When the present invention performs laser cutting on the material 3, the end of the material 3 to be cut is clamped by the clamping assembly (the function realized by the clamping assembly belongs to the conventional technical means in this field, and the specific structure is not described). When the chuck 2 drives the material 3 to rotate, the material 3 will drive the clamping assembly and the rotating ring 52 to rotate synchronously. Since the rotating ring 52 is slidably connected with the two sets of fixed frames 51, and the two sets of fixed frames 51 are fixedly installed under the second mounting seat 5, the clamping assembly can suppress the material 3 from jumping when clamping the material 3, avoid the instability of the laser focus position, and thus affect the incision quality.

[0028] like Figure 7-Figure 8 As shown, the grinding assembly includes a movable seat 4242, a grinding motor 4243 and a grinding wheel 4244. The grinding motor 4243 is arranged inside the movable seat 4242, and the grinding wheel 4244 is arranged at one end of the movable seat 4242 close to the center line of the workbench 42. The grinding motor 4243 and the grinding wheel 4244 are connected by a belt drive assembly 4245.

[0029] When the present invention performs laser cutting on the material 3, the grinding assembly is moved away from the material 3 by the first cylinder 4241, the material 3 is clamped by the chuck 2, and the end of the material 3 to be cut is clamped by the clamping assembly. After the end of the material 3 to be cut is cut, the staff can close the clamping assembly and the chuck 2, and then manually or mechanically move the cut material 3 to the position of the collecting cover 61 for a distance, and at the same time move the material 3 to be cut to a position away from the second mounting seat 5 for a distance, until the end face of the cut material 3 and the end face of the material 3 to be cut are aligned with the two end faces of the grinding wheel 4244, and then ... move the cut material 3 to the position of the collecting cover 61 for a distance, and then move the material 3 to be cut to the position away from the second mounting seat 5 for a distance, and then the staff can close the clamping assembly and the chuck 2, and then move the material 3 to be cut to the position of the collecting cover 61 for a distance, and then move the material 3 to be cut to the position of the collecting cover 61 for a distance, and then move the material 3 to be cut to the position of the collecting cover 61 for a distance, and then move the material 3 to be cut to the position of the collecting cover 61 for a distance, and then move the material 3 to be cut to the position of the collecting cover 61 for a distance, and then move the material The operator can turn on the clamping assembly, the rotating motor 54 and the chuck 2, clamp the cut material 3 through the clamping assembly, drive the cut material 3 to rotate through the rotating motor 54 and the transmission gear 53, clamp the material 3 to be cut through the chuck 2 and rotate the material 3 to be cut, finally make the grinding assembly close to the material 3 through the first cylinder 4241, drive the grinding wheel 4244 to rotate through the grinding motor 4243 and the belt drive assembly 4245, and grind the end faces of the cut material 3 and the end faces of the material 3 to be cut through the two ends of the grinding wheel 4244 to eliminate the slag existing in the laser cutting part of the material 3.

[0030] like Figure 2-Figure 5 As shown, the smoke collection mechanism includes a filter chamber and a fan 46. A filter assembly is arranged in the filter chamber. The air inlet end of the fan 46 is connected to the exhaust pipe 422 through the exhaust channel 47. The air outlet end of the fan 46 is connected to the filter chamber. An air outlet channel 431 is arranged at one end of the filter chamber away from the fan 46.

[0031] like Figure 5 As shown, a flow detection element 43 is arranged above the air outlet channel 431, and the filter assembly includes a filter frame 48 and a reversing motor. The reversing motor is arranged at the side end of the filter cavity and connected to the filter frame 48. Three groups of through holes are arranged on the filter frame 48, and a group of filter screens are arranged in each group of through holes. The flow detection element 43 is electrically connected to the reversing motor.

[0032] When the present invention is cutting and grinding materials, the fan 46 will continuously generate a set of suction force to transport smoke and various debris into the filter chamber, and a set of filter screens near the air outlet end of the fan 46 will intercept particles and various debris in the smoke. The wind speed of the air outlet channel 431 is monitored by the flow detection element 43. When a set of filter screens near the air outlet end of the fan 46 is blocked, the wind speed of the air outlet channel 431 will decrease accordingly. At this time, the staff can turn on the reversing motor and drive the filter frame 48 to rotate through the reversing motor to replace a set of filter screens near the air outlet end of the fan 46. Compared with the filter components currently used in laser cutting equipment, the present invention can automatically replace the filter screens without stopping the machine to ensure work efficiency.

[0033] like Figure 5 As shown, the smoke and dust collection mechanism also includes a waste channel 45, which is connected to the filter chamber, and a baffle 451 is provided inside the waste channel 45. The side end of the baffle 451 is provided with a second cylinder 44. When the present invention is working normally, the three groups of through holes on the filter frame 48 are respectively aligned with the air outlet end of the fan 46, the air outlet channel 431, and the waste channel 45. At the same time, the baffle 451 is located in the waste channel 45, and the baffle 451 separates the waste channel 45 from the external environment. When the staff needs to clean a group of filters, the filter frame 48 can be driven to rotate by the reversing motor until the filter to be cleaned is aligned with the waste channel 45, and then the outlet of the waste channel 45 is closed. The mouth end is connected to the external waste recovery system, and the baffle 451 is kept away from the waste channel 45 through the second cylinder 44. At this time, the staff only needs to turn on the fan 46 and close the air outlet end of the flow detection element 43 to allow the external air to flow along the exhaust channel 47, the filter frame 48, and the waste channel 45. During the flow of the external air, the smoke particles and various debris on the filter screen to be cleaned will enter the external waste recovery system with the external air. Through the above technical scheme, the present invention can collect smoke and grinding debris through the fan 46 on the one hand, and can also clean the filter assembly through the fan 46 on the other hand, so as to reduce the labor intensity of the staff.

[0034] The working principle of the present invention is as follows: when cutting the material 3, the staff needs to pass the material 3 through the working frame 42 and be concentric with the working frame 42, and then clamp the end of the material 3 to be cut by the clamping assembly, and isolate the two ends of the working frame 42 from the external environment through two sets of sealing assemblies, and then drive the laser cutting head 41 to move downward and extend into the working frame 42 through the lifting module 49, and drive the material 3 to rotate through the chuck 2, and cut the material 3 through the laser cutting head 41. During the cutting process of the material 3, the smoke collection mechanism will continuously generate a set of suction force, and then collect and process the smoke generated during the cutting process. After the end of the material 3 to be cut is cut off, the staff can close the clamping assembly and the chuck 2, and then manually or mechanically move the cut end of the material 3. The material 3 is moved a certain distance toward the position of the collecting cover 61, and the material 3 to be cut is moved a certain distance away from the second mounting seat 5 until the end face of the cut material 3 and the end face of the material 3 to be cut are aligned with the two end faces of the grinding wheel 4244. Then the staff can open the clamping assembly and the chuck 2, clamp the cut material 3 by the clamping assembly, and clamp the material 3 to be cut by the chuck 2. Finally, the grinding assembly is brought close to the material 3 by the first cylinder 4241, and the end faces of the cut material 3 and the end faces of the material 3 to be cut are ground by the two end faces of the grinding wheel 4244 to eliminate the slag existing in the laser cutting part of the material 3. When the grinding is completed, the staff can close the clamping assembly to take away the cut material 3.
