Description

Technical Field

[0001] The present invention relates to the technical field of hole opening, and particularly relates to a laser cutting machine for cabinet production. Background Art

[0002] Mechanical experiment equipment is very important teaching equipment in physics experiment teaching. It integrates various instruments and tools required for multiple mechanical experiments, can assist in learning to conduct various mechanical experiments. A certain part of the cabinet body will be set in an arc shape, and laser holes will be opened on the arc-shaped part to form an arc-shaped sieve plate, so as to facilitate the screening of small balls in the collision experiment to meet the use of small balls of the same size for the experiment, and then ensure the accuracy and repeatability of the experiment. When opening holes in the arc-shaped plate, the arc-shaped plate will be fixed on the workbench first, and the arc-shaped plate will be opened according to requirements through the laser hole opening equipment to form an arc-shaped sieve plate. After processing, the arc-shaped sieve plate can be welded and fixed on the mechanical cabinet.

[0003] A Chinese patent document with the publication number of CN104646806B discloses a cylinder hole opening tooling, which is applicable to hole opening operations on the surface of a cylinder. It includes a gantry. A centering cutting device is provided on the cross beam of the gantry. The centering cutting device includes a centering column. A cylindrical cam is installed on the upper part of the centering column. A curve groove is provided on the cylindrical cam. Below the cylindrical cam and on one side of the centering column, there is a cutting head that moves up and down and rotates along the centering column. The cutting head includes a guide rod and a mounting seat for the cutting gun. The distance from the muzzle of the cutting gun to the center line of the centering column is consistent with the radius of the hole to be opened. The height difference from the lowest point to the highest point of the curve groove is consistent with the height difference from the lowest point to the highest point of the hole to be opened. The trajectory of the curve groove of the cylindrical cam makes the distance between the rotating cutting head driven by the guide rod and the surface of the cylinder always remain unchanged. Among them, the structure of the cylindrical cam is formed by injection molding after three-dimensional modeling.

[0004] When the above-mentioned hole opening device in the prior art works, a required cylindrical cam is selected according to the diameter of the hole to be opened, and the cylinder hole opening tooling is installed. During use, the cylinder to be opened is placed in the water tank, and a part of water is added to the water tank. The gantry is erected on the upper edge of the water tank, and the gantry is pushed to move the overall tooling to the position where the hole needs to be opened. The left and right adjusting devices on the upper part of the centering cutting device are adjusted so that the positioning pointer on the centering column positions to the center of the hole to be opened, ensuring that the center is located at the highest point of the cylinder. The height of the plasma cutting gun is adjusted through the up and down adjusting device on the mounting seat connected to the cutting gun, and the plasma cutting gun is driven to perform the cutting work to complete the hole opening operation on the surface of the cylinder.

[0005] However, the above-mentioned prior art still has the following deficiencies: When opening a hole in the side of the arc-shaped plate, the diameter of the waste material cut by laser is smaller than the diameter of the hole to be opened, and the waste material cut by laser will fall vertically under the action of its own gravity. At this time, once the bottom of the waste material is blocked by the inner wall of the hole, the waste material will collide with the inner wall of the hole to be opened and then break away from the arc-shaped plate, easily causing the deformation of the hole wall, thus affecting the hole-opening quality and having an impact on subsequent use. Summary of the Invention

[0006] The present invention provides a laser cutting machine for cabinet production, aiming to solve the problem in the prior art that when opening a hole in the side of an arc-shaped plate by an existing hole-opening device, the diameter of the waste material cut by laser is smaller than the diameter of the hole to be opened, and the waste material cut by laser will fall vertically under the action of its own gravity. At this time, once the bottom of the waste material is blocked by the inner wall of the hole, the waste material will collide with the inner wall of the hole to be opened and then break away from the arc-shaped plate, easily causing the deformation of the hole wall, thus affecting the hole-opening quality.

After the hole-cutting part is cut, a waste material block is formed and is magnetically adsorbed by the magnet, so as to receive the cut waste material block, and drive the waste material block to move out of the hole by the movable part, so as to avoid the collision between the waste material block and the inner wall of the hole to be opened when the waste material block falls vertically under the action of its own gravity, thus avoiding the deformation of the hole wall and affecting the hole-opening quality.

[0041] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0042] As Figures 1 to 9 shown, the laser cutting machine for cabinet production of the present invention includes a driving mechanism 1, a control cabinet, a drilling gun head 2, a support table 3 and a material receiving mechanism 4. The drilling gun head 2 is a plasma cutting gun head. The drilling gun head 2 is connected to the driving mechanism 1. The driving mechanism 1 can drive the drilling gun head 2 to cut and drill the arc plate A, so as to cut off the scrap block A1. The control cabinet can set a three-dimensional trajectory planning for the driving mechanism 1 (the control cabinet is a prior art and is not shown in the figure), so that the driving mechanism 1 can drive the drilling gun head 2 to move along the set three-dimensional trajectory planning. The support table 3 is located below the drilling gun head 2 and is used for supporting and positioning the arc plate A. The material receiving mechanism 4 is connected to the support table 3 and can receive the scrap block A1 to prevent the scrap block A1 from colliding with the inner wall of the drilled hole when falling vertically under its own gravity, thereby avoiding the deformation of the hole wall and affecting the drilling quality.

[0043] Lift the arc-shaped plate A onto the support table 3, and the support table 3 positions and supports the arc-shaped plate A. The axis direction of the arc-shaped plate A is the X-axis direction. Then, drive the hole-opening gun head 2 to the position to be cut and opened on the arc-shaped plate A through the driving mechanism 1. Next, the material receiving mechanism 4 magnetically fixes the position to be cut and opened on the arc-shaped plate A, and the driving mechanism 1 drives the hole-opening gun head 2 to perform cutting and opening operations on the arc-shaped plate A, so that a waste block A1 is formed at the position to be cut and opened on the arc-shaped plate A. The material receiving mechanism 4 magnetically fixes the cut waste block A1. Finally, start the material receiving mechanism 4 again to remove the cut waste block A1. During the process of removing the waste block A1, the waste block A1 does not contact the hole wall of the opened hole, so as to avoid the collision between the waste block A1 and the inner wall of the opened hole when the waste block A1 vertically falls under the action of its own gravity, thereby avoiding the deformation of the hole wall and affecting the hole-opening quality.

[0044] As Figure 1 , Figure 2 and Figure 9 shown, the driving mechanism 1 includes a gantry bracket 11, a first moving member 12, a second moving member 13, a height adjuster 14, a rotating member 15, an arc voltage monitoring and adjusting member 16. The first moving member 12 is installed on the gantry bracket 11 and can move along the X-axis direction. The second moving member 13 is installed on the first moving member 12 and can move along the Y-axis direction. The height adjuster 14 is connected to the second moving member 13 and can move along the Z-axis direction. The rotating member 15 is connected to the height adjuster 14 and can drive the hole-opening gun head 2 to rotate, so that the hole-opening gun head 2 can perform hole-opening operations on the arc-shaped plate A. The adjusting member 16 is connected to the rotating member 15, and the hole-opening gun head 2 is connected to the adjusting member 16. The adjusting member 16 can adjust the cutting angle of the hole-opening gun head 2, so as to perform laser cutting and opening on the arc-shaped plate A according to requirements. The arc voltage monitoring is connected to the rotating member 15 (the arc voltage monitoring is a prior art and not shown in the figure), which is used to monitor the arc voltage data when the hole-opening gun head 2 cuts and opens the arc-shaped plate A, feedback the distance change between the hole-opening gun head 2 and the arc-shaped plate A, and transmit this signal to the height adjuster 14. The height adjuster 14 adjusts the distance between the hole-opening gun head 2 and the arc-shaped plate A according to the signal, so as to achieve three-dimensional cutting and perform laser cutting and opening on the arc-shaped plate A.

[0045] Start the first walking part 12 to drive the hole-opening gun head 2 to move along the X-axis direction to the set position, start the second walking part 13 to drive the hole-opening gun head 2 to move along the Y-axis direction to the set position, start the height adjuster 14 to drive the hole-opening gun head 2 to move along the Z-axis direction to the set position, start the adjusting part 16 to drive the hole-opening gun head 2 to rotate, so as to adjust the cutting angle of the hole-opening gun head 2, so as to perform laser cutting and hole-opening on the arc-shaped plate A subsequently. Start the rotating part 15 to drive the hole-opening gun head 2 to rotate, so as to perform cutting and hole-opening on the arc-shaped plate A. During this process, the arc voltage monitor monitors the arc voltage data when the hole-opening gun head 2 cuts and opens the hole on the arc-shaped plate A, feeds back the distance change between the hole-opening gun head 2 and the arc-shaped plate A, and transmits this signal to the height adjuster 14. The height adjuster 14 adjusts the distance between the hole-opening gun head 2 and the arc-shaped plate A according to the signal, so as to realize three-dimensional cutting, and then cut the required holes on the arc-shaped plate A. The cut waste is the waste block A1.

[0046] As Figure 1 and Figure 3 shown, the support table 3 includes a table body 31 and a positioning plate 32. The table body 31 is used to support the arc-shaped plate A. The axis of the arc-shaped plate A is in the X-axis direction. There are four positioning plates 32. The four positioning plates 32 are all connected to the table body 31. The four corners of the arc-shaped plate A can be positioned through the four positioning plates 32 to prevent the arc-shaped plate A from shifting, so as to ensure the hole-opening quality of the arc-shaped plate A. The four positioning plates 32 and the table body 31 can be detachably connected by bolts.

[0047] As Figure 1 , Figures 3 to 9 shown, the material receiving mechanism 4 includes a swing arm 41, a collection box 42, a material receiving part 43, a material discharging part 44, a shielding part 45 and a first driving source 46. The swing arm 41 is rotatably connected to the table body 31 and is coaxially arranged with the arc-shaped plate A. There is an installation opening at the top of the table body 31. The first driving source 46 is connected in the installation opening at the top of the table body 31. The first driving source 46 is a motor. The output shaft of the first driving source 46 is connected to the swing arm 41. Starting the first driving source 46 can drive the swing arm 41 to rotate along the X-axis. The collection box 42 is connected to the swing arm 41. One end of the collection box 42 away from the swing arm 41 is open, and one end of the collection box 42 away from the swing arm 41 is in contact with the inner wall of the arc-shaped plate A. The collection box 42 can collect the waste slag formed during cutting and the cut waste block A1. The material receiving part 43 is connected in the collection box 42 and is used to remove the cut waste block A1. The material discharging part 44 is connected in the collection box 42 and is used to discharge the waste block A1 and waste slag collected in the collection box 42. The shielding part 45 is connected in the collection box 42 and is used to shield the material receiving part 43 to prevent the waste slag during the cutting and hole-opening of the arc-shaped plate A from splashing into the material receiving part 43 and affecting the normal operation of the material receiving part 43.

[0048] Start the driving source 46. The swing arm 41 drives the collection box 42 to swing radially along the arc-shaped plate A, so that the material receiving part 43 moves to the opening part to be cut on the arc-shaped plate A. Start the magnetic adsorption between the material receiving part 43 and the opening part to be cut on the arc-shaped plate A. After the opening gun head 2 cuts and opens the hole on the arc-shaped plate A, a waste block A1 is formed at the opening part to be cut on the arc-shaped plate A, and the generated waste block A1 is magnetically adsorbed by the material receiving part 43, preventing the waste block A1 from falling under its own gravity after being completely separated from the arc-shaped plate A, thereby avoiding the collision between the waste block A1 and the inner wall of the opened hole. Moreover, the waste slag generated when the opening gun head 2 cuts and opens the hole on the arc-shaped plate A falls into the collection box 42, preventing the waste slag from affecting the horizontal placement of the next arc-shaped plate A after falling onto the table body 31. After cutting and opening the hole, the material receiving part 43 drives the waste block A1 to move radially along the arc-shaped plate A into the collection box 42, so that the waste block A1 does not contact the inner wall of the hole opened on the arc-shaped plate A. Then the waste block A1 falls into the collection box 42. Finally, the discharging part 44 discharges the waste block A1 and the waste slag, and can directly discharge the waste block A1 outside the support table 3 for collection, without manual collection of the waste block A1.

[0049] Continue to refer to Figure 1 、 Figures 3 to 9 As shown, a first cavity 421, a second cavity 422 and a discharge port 423 are arranged in the collection box 42. There are two first cavities 421, the second cavity 422 is arranged between the two first cavities 421, there are two groups of discharge ports 423, each group of discharge ports 423 has two, and the two discharge ports 423 in the same group are arranged front and back along the X-axis direction. The two discharge ports 423 are respectively arranged on the inner walls of the two first cavities 421. The first cavity 421 is used to hold the waste block A1 after cutting and opening the hole, and the second cavity 422 is used to install the material receiving part 43. During use, the discharging part 44 can discharge the waste block A1 and the waste slag from the discharge port 423.

[0050] Continue to refer to Figure 1 、 Figures 3 to 9As shown, the material receiving member 43 includes a screw rod 431, a second driving source 432, a moving part 433, a telescopic part 434, a movable part 435 and a magnet 436. The screw rod 431 is rotatably connected in the second cavity 422. The screw rod 431 is arranged along the X-axis direction. The second driving source 432 is connected to the collecting box 42. The second driving source 432 is a motor. The output shaft of the second driving source 432 is connected to the screw rod 431. The moving part 433 is limitedly slidably connected in the second cavity 422. The moving part 433 is threadedly connected to the screw rod 431, and the moving part 433 is threadedly connected to the screw rod 431. One end of part 433 extends out of cavity 422, and driving source 432 is started to drive screw 431 to rotate. At this time, under the limit of cavity 422 on moving part 433, moving part 433 moves along the X-axis direction. Telescopic part 434 is connected in moving part 433, and movable part 435 is inserted in one end of moving part 433 extending out of cavity 422. Telescopic part 434 is a cylinder, and the telescopic end of telescopic part 434 is connected to movable part 435, and magnet 436 is connected to one end of movable part 435 extending out of moving part 433.

[0051] The swing arm 41 drives the collecting box 42 to rotate along the X-axis direction, so that the material receiving piece 43 moves to the X-axis direction of the part to be cut and opened on the arc plate A, and starts the driving source 2 432 to drive the screw rod 431 to rotate, so as to drive the moving part 433 to move along the X-axis direction, until the moving part 433 drives the movable part 435 and the magnet 436 to move to the cutting and opening part of the arc plate A, and then starts the telescopic part 434 to drive the movable part 435 to approach the arc plate A, until the magnet 436 contacts and magnetically adsorbs the cutting and opening part of the arc plate A, thereby completing the magnetic fixation of the cutting and opening part of the arc plate A, so as to avoid the waste block A1 under the cutting and opening from falling vertically under its own gravity, thereby avoiding the collision between the waste block A1 and the inner wall of the opening and causing deformation of the hole wall, thereby ensuring the quality of the cutting and opening of the arc plate A.

[0052] After the cutting and opening operation of the arc plate A is completed, the waste block A1 is fixed by the magnetic force of the magnet 436. At this time, the telescopic part 434 is started to drive the movable part 435 to move in the direction of extending into the movable part 433, and the cut waste block A1 is driven by the magnet 436 to separate from the opened hole, so that the waste block A1 moves along the radial direction of the arc plate A, and the waste block A1 does not contact the inner wall of the hole opened on the arc plate A. After the magnet 436 extends into the movable part 433, the magnet 436 is separated from the waste block A1 under the obstruction of the movable part 433. As the distance between the magnet 436 and the waste block A1 increases, the magnetic force between the magnet 436 and the waste block A1 gradually decreases until the waste block A1 overcomes the magnetic force between the magnet 436 and the waste block A1 through its own gravity and falls into one of the cavities 421.

[0053] Continue to refer Figure 1 , Figures 3 to 9As shown, the discharging member 44 includes a driving roller 441, a conveyor belt 442 and a driving source three 443. There are two driving rollers 441, which are respectively rotatably connected to the front and rear sides of the collection box 42, and the axes of the two driving rollers 441 are both perpendicular to the X-axis direction. There are two conveyor belts 442, and both of the two conveyor belts 442 are drivingly connected to the two driving rollers 441. The two conveyor belts 442 can support the waste slag and waste block A1 generated during cutting and opening holes, and the two conveyor belts 442 and the two driving rollers 441 can be driven to convey and discharge the waste slag and waste block A1, so as to avoid manual cleaning when the waste slag and waste block A1 fall onto the table body 31. The two conveyor belts 442 respectively penetrate through two groups of discharging ports 423, and the two conveyor belts 442 are respectively located in two cavities one 421. The driving source three 443 is connected to the collection box 42. The driving source three 443 is a motor, and the output shaft of the driving source three 443 is connected to one of the driving rollers 441. The conveyor belt 442 is made of flexible metal material to avoid damage to the conveyor belt 442 caused by the waste slag generated during cutting and opening holes.

[0054] The cut waste block A1 falls onto the conveyor belt 442 in the cavity one 421. Start the driving source three 443 to drive the transmission between the two conveyor belts 442 and the two driving rollers 441, so as to drive the waste block A1 to be discharged from the discharging port 423 on the collection box 42, facilitating the collection of the cut waste block A1.

[0055] Continue to refer to Figure 1 、 Figures 3 to 9 As shown, there are two shielding members 45, and the two shielding members 45 are respectively connected to the front side and the rear side of the inner wall of the collection box 42. The two shielding members 45 can shield the cavity two 422 to avoid waste slag splashing onto the lead screw 431 and affecting the movement of the moving part 433.

[0056] The shielding member 45 includes a mounting box 451, a coil roller 452, a guide roller 453, a shielding belt 454, a torsion spring 455 and a scraping portion 456. The mounting box 451 is connected to the collection box 42. The coil roller 452 is rotatably connected inside the mounting box 451. An opening is provided at the bottom of one side of the mounting box 451 close to the moving portion 433. The guide roller 453 is rotatably connected in the opening. One end of the shielding belt 454 is wound around the coil roller 452. The other end of the shielding belt 454 is connected to the moving portion 433, and the guide roller 453 guides the shielding belt 454 so that the shielding belt 454 horizontally shields the top of the cavity two 422. The torsion spring 455 is connected between the coil roller 452 and the mounting box 451 and is used to drive the coil roller 452 to wind up the shielding belt 454. The shielding belt 454 is made of a flexible metal material. The scraping portion 456 is connected to one side of the mounting box 451 close to the moving portion 433 and is used to scrape off the waste slag on the shielding belt 454 when the coil roller 452 winds up the shielding belt 454, so as to avoid affecting the winding of the shielding belt 454.

[0057] Working principle: Lift the arc-shaped plate A onto the table body 31, and the axis of the arc-shaped plate A is in the X-axis direction, and position the four corners of the arc-shaped plate A through the four positioning plates 32.

[0058] Start the driving source one 46, and drive the collection box 42 to swing along the radial direction of the arc-shaped plate A by the swing arm 41, so that the material receiving member 43 moves to the X-axis direction of the part to be cut and opened on the arc-shaped plate A. Start the driving source two 432 to drive the lead screw 431 to rotate, so as to drive the moving portion 433 to move along the X-axis direction until the moving portion 433 drives the movable portion 435 and the magnet 436 to move to the part to be cut and opened on the arc-shaped plate A. Then start the telescopic portion 434 to drive the movable portion 435 to approach the arc-shaped plate A until the magnet 436 is magnetically adsorbed to the cutting and opening portion of the arc-shaped plate A, thereby completing the magnetic adsorption fixation of the part to be cut and opened on the arc-shaped plate A.

[0059] When the moving portion 433 moves along the X-axis direction, it pulls the shielding belt 454 of one of the shielding members 45 to unwind, and the shielding belt 454 of the other shielding member 45 is wound up under the action of the torsion spring 455 and the coil roller 452 on this shielding member 45, so that the shielding belts 454 of the two shielding members 45 always shield the cavity two 422, and the scraping portion 456 cleans the waste residue attached to the upper surface of the shielding belt 454 being wound up, so as to avoid the waste residue being wound in the shielding belt 454, and further avoid affecting the winding of the shielding belt 454.

[0060] Start the walking part 12 to drive the hole punching gun head 2 to move to the set position along the X-axis direction, start the walking part 2 13 to drive the hole punching gun head 2 to move to the set position along the Y-axis direction, start the height adjuster 14 to drive the hole punching gun head 2 to move to the set position along the Z-axis direction, start the adjustment part 16 to drive the hole punching gun head 2 to rotate to adjust the cutting angle of the hole punching gun head 2, start the rotating part 15 to drive the hole punching gun head 2 to rotate, thereby cutting and opening a hole in the arc plate A. During this process, the arc voltage monitoring is used to monitor the arc voltage data when the hole punching gun head 2 cuts and opens a hole in the arc plate A, and the change in the distance between the hole punching gun head 2 and the arc plate A is fed back, and this signal is transmitted to the height adjuster 14, and the height adjuster 14 adjusts the distance from the hole punching gun head 2 to the arc plate A according to the signal, thereby realizing three-dimensional cutting, and cutting off the part to be cut of the arc plate A to form a waste block A1.

[0061] After the operation of cutting and opening the arc plate A is completed, the waste block A1 is magnetically fixed by the magnet 436, and the telescopic part 434 is started to drive the movable part 435 to move in the direction of extending into the movable part 433, and the cut waste block A1 is driven by the magnet 436 to separate from the opened hole, and the waste block A1 does not contact the hole wall. After the magnet 436 extends into the movable part 433, the magnet 436 is separated from the waste block A1 under the obstruction of the movable part 433. As the distance between the magnet 436 and the waste block A1 increases, the magnetic force between the magnet 436 and the waste block A1 gradually decreases, until the waste block A1 overcomes the magnetic force between the magnet 436 and the waste block A1 through its own gravity and falls into one of the cavities 421, and is supported by the conveyor belt 442.

[0062] When the movable part 433 moves along the X-axis direction, the shielding belt 454 on one of the shielding members 45 is unwound, and the shielding belt 454 on the other shielding member 45 is reeled under the action of the torsion spring 455 and the winding roller 452 on the shielding member 45, so that the shielding belts 454 on the two shielding members 45 always shield the cavity 2 422.

[0063] The cut waste block A1 falls onto the conveyor belt 442 in the cavity 1 421, and the driving source 3 443 is started to drive the transmission between the two conveyor belts 442 and the two transmission rollers 441, thereby driving the waste block A1 to be discharged from the discharge port 423 on the collection box 42, and the discharged waste block A1 can be collected by an external collection frame.

A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
