Description

Technical Field

[0001] The invention relates to the technical field of water tank production equipment, and more specifically to an automatic plasma arc cutting device for a stainless steel water tank. Background Art

[0002] A stainless steel sink is a product made of stainless steel as raw material, which is processed on the main body by one-piece stretching or welding, and then formed after surface treatment. It is an indispensable part of cabinet installation, and the final product is used in modern kitchens as one of the indispensable tools for washing vegetables or dishes.

[0003] In the prior art, in the production process of sinks, a plasma arc cutting device is often used to make holes in stainless steel sinks. When plasma arc cutting stainless steel, due to the high melting point and high hardness of the material, oxide scale and burrs are easily generated on the cut surface after cutting. Not only are scratches easily caused when picking up, but corrosion and other problems may also occur in subsequent use. Therefore, grinding is usually required to remove the oxide scale, make the surface smooth, and improve corrosion resistance. Currently, during production, most of the grinding is performed by staff in subsequent steps, which is not only inefficient, but also has a poor grinding effect, which is not convenient for actual production operations.

[0021] A stainless steel water tank automatic plasma arc cutting device, including a machine tool body 1, a mechanical arm 4, and a control console 5. Specifically, the mechanical arm 4 and the control console 5 are both prior art, and their specific working principles are not repeated here. The mechanical arm 4 and the control console 5 are both arranged on the side of the machine tool body 1, and a clamping mechanism is arranged on the top of the machine tool body 1. The clamping mechanism is used to align and clamp the water tank. A square seat 3 is fixedly installed at one end of the mechanical arm 4, and a mounting hole is opened on one side of the square seat 3. A plasma arc cutting head 23 is fixedly installed in the mounting hole. A circular groove is opened on the other side of the square seat 3. A grinding mechanism is provided in the groove, and the grinding mechanism includes a circular shaft 29, which is movably arranged in the circular groove. Two telescopic grooves are provided on the outer wall of the circumferential side of the circular shaft 29, and multi-stage telescopic rods 40 are fixedly installed in the two telescopic grooves. The ends of the two multi-stage telescopic rods 40 are fixedly installed with arc-shaped grinding sheets 39 and are connected through an adjusting component. A cleaning component is provided in the circular groove, and the cleaning component includes an annular plate 42, which is rotatably arranged in the circular groove, and a plurality of cleaning brushes 46 are provided on the inner wall of the circumferential side of the annular plate 42, and the plurality of cleaning brushes 46 are used to clean the two arc-shaped grinding sheets 39.

[0022] like Figure 2 and Figure 4 As shown, the clamping mechanism includes two rectangular plates 2, two slide grooves are provided on the top of the machine tool body 1, and the inner walls of the sides of the two slide grooves close to each other are provided with connecting holes, and the opposite sides of the two slide grooves are jointly rotatably installed with bidirectional screw rods 8, and the outer walls of the peripheral sides of the two bidirectional screw rods 8 are fixedly sleeved with synchronous pulleys 10, and the two synchronous belt pulleys 10 are jointly meshed and installed with synchronous belts 11. Through the meshing action of the two synchronous pulleys 10 and the synchronous belt 11, the two bidirectional screw rods 8 can be driven to realize the synchronous rotation function to prevent the two rectangular plates 2 from getting stuck during the movement. A clamping motor 12 is fixedly installed on the side of the machine tool body 1. Specifically, the clamping motor 12 can be controlled by a PLC controller, and the output shaft of the clamping motor 12 is connected to one of the bidirectional screw rods 8. The ends of the two bidirectional screw rods 8 are connected, and two slide plates 9 are threadedly installed on the two bidirectional screw rods 8. The tops of the four slide plates 9 are fixedly connected to the bottoms of the two rectangular plates 2 respectively. The sides of the two rectangular plates 2 are provided with square holes, and square slide rods 14 are slidably installed in the two square holes. The sides of the two square slide rods 14 close to each other are fixedly installed with clamps 15, and the sides of the two clamps 15 are provided with anti-slip pads 16. The sides of the two square slide rods 14 away from each other are fixedly installed with square plates 17, and the outer walls of the surrounding sides of the two square slide rods 14 are sleeved with compression springs 18. Through the elastic action of the compression springs 18, when the extrusion limit on the clamps 15 is released, the elastic action of the compression springs 18 can drive the square plates 17 to achieve the reset function.

[0023] Specifically, start the clamping motor 12 to drive one of the bidirectional screws 8 to rotate, and through the meshing action of the two synchronous pulleys 10 and the synchronous belt 11, drive the other bidirectional screw 8 to rotate synchronously, and under the action of the thread, drive the two rectangular plates 2, two square slide bars 14, and two clamps 15 to move toward each other synchronously, and push the stainless steel water sink to the middle position of the machine tool body 1. When the two clamps 15 are in contact with the surface of the stainless steel water sink, the extrusion and limiting effect of the stainless steel water sink can keep the two clamps 15 stationary. At this time, since the rectangular plate 2 continues to move, it has a stretching effect on the compression spring 18.

[0024] like Figure 5 As shown, the clamping mechanism also includes four telescopic shafts 21, rectangular holes are opened on the sides of the two rectangular plates 2, and the relative inner walls of the four rectangular holes are jointly fixedly installed with limit shafts 13, and the outer walls of the surrounding sides of the four limit shafts 13 are slidably sleeved with linkage sliders 20, and the sides of the four linkage sliders 20 are rotatably installed with first connecting rods 19, and the other ends of the four first connecting rods 19 are respectively rotatably installed on the two side parts of the two square plates 17, and the four telescopic shafts 21 are respectively fixedly installed on the sides of the four linkage sliders 20, and the outer walls of the surrounding sides of each two matching telescopic shafts 21 are jointly slidably sleeved with telescopic sleeves 22. Through the setting of the first connecting rod 19, when the square plate 17 is in a stationary state and the rectangular plate 2 is in a moving state, the connecting action of the first connecting rod 19 can drive the linkage slider 20 to realize the horizontal movement function.

[0025] Specifically, when the splint 15 is in a stationary state and the rectangular plate 2 continues to move, the connecting action of the first connecting rod 19 can drive the linkage slider 20 and the telescopic shaft 21 to move synchronously, thereby driving the two telescopic sleeves 22 to move synchronously toward each other, and cooperating with the action of the two splints 15, the stainless steel water tank is pushed to the center position of the machine tool body 1 to complete the alignment operation.

[0026] like Figure 1 As shown, the clamping mechanism also includes a placement plate 6. A placement groove is opened on the top of the machine tool body 1, and a placement plate 6 is movably installed in the placement groove. A hydraulic cylinder 7 is fixedly installed on the bottom of the machine tool body 1. Specifically, the hydraulic cylinder 7 can be controlled by a PLC controller. The output end of the hydraulic cylinder 7 passes through the machine tool body 1 and is fixedly connected to the bottom of the placement plate 6. The placement plate 6 is located at the center position of the two rectangular plates 2. Through the arrangement of the hydraulic cylinder 7 and the placement plate 6, the stainless steel water tank can be clamped when it is at a certain height, thereby preventing damage to the machine tool body 1 during subsequent cutting.

[0027] Specifically, the hydraulic cylinder 7 drives the placement plate 6 to move upward, so that the stainless steel water tank is placed on the top of the placement plate 6, which is convenient for aligning and clamping the stainless steel water tank. After the clamping operation is completed, the hydraulic cylinder 7 drives the placement plate 6 to reset, thereby avoiding certain damage to the placement plate 6 and the surface of the machine tool body 1 during the cutting process.

[0028] like Figure 6 and Figure 7 As shown, the grinding mechanism also includes a first ear plate 27, and two limit grooves 28 are provided on the inner wall of the circumferential side of the circular groove. The first ear plate 27 is slidably arranged in the two limit grooves 28. The bottom end of the circular shaft 29 is rotatably connected to the top of the first ear plate 27. A transmission cavity is provided in the square seat 3, and a screw guide sleeve 25 is rotatably installed on the bottom inner wall of the transmission cavity. A motor groove is provided on the bottom inner wall of the transmission cavity, and a drive motor 24 is fixedly installed in the motor groove. Specifically, the drive motor 24 can be controlled by a PLC controller, and the output shaft of the drive motor 24 is connected to the bottom end of the screw guide sleeve 25. A screw 26 is installed in the screw guide sleeve 25 through internal threads, and the top end of the screw 26 passes through the transmission cavity and is connected to the bottom of the first ear plate 27. Through the connection between the screw guide sleeve 25 and the screw 26, when the screw guide sleeve 25 rotates, it can drive the screw 26 to achieve lifting movement through the action of the thread.

[0029] Specifically, the drive motor 24 is started to drive the screw guide sleeve 25 to rotate, thereby driving the screw 26 and the first ear plate 27 to realize the lifting and lowering movement function through the action of the thread and the limiting action of the first ear plate 27 and the two limiting grooves 28, so as to facilitate the adjustment of the height position of the circular shaft 29 and the arc-shaped grinding sheet 39.

[0030] like Figure 8 As shown, the grinding mechanism also includes a grinding motor 33. Specifically, the grinding motor 33 can be controlled by a PLC controller. The grinding motor 33 is fixedly installed at the bottom of the first ear plate 27. The output shaft of the grinding motor 33 passes through the first ear plate 27 and is fixedly sleeved with a transmission gear 34. The outer wall of the circumferential side of the circular shaft 29 is fixedly sleeved with a matching gear 35. The matching gear 35 is meshed and installed with the transmission gear 34. Through the meshing action of the transmission gear 34 and the matching gear 35, the rotation function of the circular shaft 29 can be achieved by driving the grinding motor 33 to drive the circular shaft 29.

[0031] Specifically, the grinding motor 33 is started to drive the transmission gear 34 to rotate, so that the circular shaft 29 and the two arc-shaped grinding discs 39 are driven to rotate synchronously through the meshing action of the transmission gear 34 and the matching gear 35, thereby realizing the grinding operation of the cutting hole.

[0032] like Fig. 9 and Fig.10As shown, the adjustment component includes a second ear plate 36, an ear-shaped lifting hole is provided on the circumferential outer wall of the circular shaft 29, the second ear plate 36 is slidably installed in the ear-shaped lifting hole, a mounting groove is provided on the bottom inner wall of the ear-shaped lifting hole, and an electric telescopic rod 37 is fixedly installed in the mounting groove. Specifically, the electric telescopic rod 37 can be controlled by a PLC controller, and the output end of the electric telescopic rod 37 is fixedly connected to the bottom of the second ear plate 36, and two rotating grooves are provided on the circumferential outer wall of the second ear plate 36, and second connecting rods 38 are rotatably installed in the two rotating grooves, and rotating holes are provided on the circumferential outer walls of the two multi-stage telescopic rods 40, and the other ends of the two second connecting rods 38 are rotatably installed in the two rotating holes respectively, and grinding sandpaper 41 is fixedly installed on the circumferential outer walls of the two arc-shaped grinding plates 39. Through the connection action of the two second connecting rods 38, the two arc-shaped grinding plates 39 can be driven to move synchronously toward or away from each other under the lifting action of the second ear plate 36, thereby adjusting the grinding diameter.

[0033] Specifically, starting the electric telescopic rod 37 drives the second ear plate 36 to move, which can drive the two multi-stage telescopic rods 40 and the two arc-shaped grinding plates 39 to move toward or away from each other synchronously under the connection of the two second connecting rods 38, thereby adjusting the position of the arc-shaped grinding plates 39 to facilitate adaptation to cutting holes of different diameters.

[0034] like Fig.12 As shown, an annular groove is provided on the inner wall of the circumferential side of the circular groove, and the annular plate 42 is rotatably installed in the annular groove. An annular limiting circular groove is provided on the opposite inner walls of the annular groove. Limiting circular rings 45 are rotatably installed in the two annular limiting circular grooves. The ends of the two limiting circular rings 45 close to each other are fixedly connected to the two sides of the annular plate 42 respectively. Through the action of the two limiting circular rings 45, the annular plate 42 can be limited to a certain extent to prevent the annular plate 42 from moving when rotating. Two arc plates 47 are fixedly installed on the inner wall of the circumferential side of the circular groove. Self-cleaning shafts 48 are fixedly installed on the sides of the two arc plates 47 close to each other. Through the setting of the self-cleaning shaft 48, when the annular plate 42 and multiple cleaning brushes 46 rotate, the cleaning brush 46 can be cleaned by the self-cleaning shaft 48 to improve its continuous cleaning ability. The self-cleaning shaft 48 is adapted to the multiple cleaning brushes 46.

[0035] Specifically, when the annular plate 42 rotates, it can drive multiple cleaning brushes 46 to rotate synchronously, thereby cleaning the surface of the arc-shaped grinding sheet 39. Moreover, through the setting of the self-cleaning shaft 48, when the cleaning brush 46 rotates, it can play a certain cleaning role on the cleaning brush 46, thereby improving its continuous cleaning ability.

[0036] like Figure 6 and Fig.12As shown, the cleaning component also includes a rotating shaft 30, and a rotating hole is formed at the sides of the transmission cavity and the annular groove close to each other. The rotating shaft 30 is rotatably installed in the rotating hole. The bottom end of the rotating shaft 30 extends into the transmission cavity and is fixedly sleeved with a first driven gear 31. The peripheral outer wall of the screw guide sleeve 25 is fixedly sleeved with a first driving gear 32, and the first driving gear 32 is meshingly installed with the first driven gear 31. The top end of the rotating shaft 30 extends into the annular groove and is fixedly sleeved with a second driving gear 44. The peripheral outer wall of the annular plate 42 is fixedly sleeved with a second driven gear 43, and the second driven gear 43 is meshingly installed with the second driving gear 44. With this arrangement, the transmission effect of the rotating shaft 30 can be used to enable the screw guide sleeve 25 to drive the annular plate 42 to rotate synchronously when it rotates, thereby realizing the cleaning effect of the arc-shaped grinding sheet 39 during the storage process.

[0037] Specifically, after the cutting hole grinding operation is completed, the arc-shaped grinding sheet 39 can be stored by rotating the screw guide sleeve 25, and when the screw guide sleeve 25 rotates, it can drive the rotating shaft 30 to rotate under the meshing action of the first driving gear 32 and the first driven gear 31, and then drive the annular plate 42 to realize the rotation function under the meshing action of the second driving gear 44 and the second driven gear 43, thereby realizing the cleaning effect on the surface of the arc-shaped grinding sheet 39 during the storage process, thereby improving the subsequent grinding ability.

[0038] The working principle and use process of the present invention are as follows: when in use, the stainless steel water tank is placed on the top of the placement plate 6, and the placement plate 6 and the stainless steel water tank are driven to rise to a suitable position by the hydraulic cylinder 7, and the clamping motor 12 is started to drive one of the two-way screw rods 8 to rotate, and the other two-way screw rod 8 is driven to rotate synchronously through the meshing action of two synchronous pulleys 10 and the synchronous belt 11, thereby driving the four slide plates 9 and the two rectangular plates 2 to move synchronously under the action of the thread, and when the two rectangular plates 2 move toward each other, the two square slide rods 14 and the two clamping plates 15 are driven to move synchronously, and when one of the clamping plates 15 is in contact with the stainless steel water tank, the two square slide rods 14 and the two clamping plates 15 are driven to move synchronously. When the surface is in contact, it can push the stainless steel sink to move until the other clamp plate 15 contacts its surface. When the two clamp plates 15 are in contact with the surface of the stainless steel sink, the two clamp plates 15 remain stationary through the extrusion effect. At this time, the two rectangular plates 2 continue to move. Under the connection action of multiple first connecting rods 19, the two linked sliders 20 located on the same rectangular plate 2 move toward each other synchronously, thereby driving the multiple telescopic shafts 21 and the two telescopic sleeves 22 to move synchronously. The stainless steel sink is pushed to the center position through the two telescopic sleeves 22, thereby realizing the alignment function, which is convenient for subsequent positioning and cutting operations.

[0039] The program is input through the control console 5 to control the movement of the robot arm 4, thereby driving the square seat 3 and the plasma arc cutting head 23 to move to the top of the sink, and cutting operations are performed on the edge of the sink, the hole and other parts. After the cutting operation is completed, the square seat 3 is driven by the robot arm 4 to rotate 180 degrees, and the drive motor 24 is started to drive the screw guide sleeve 25 to rotate, so that under the threaded action of the screw guide sleeve 25 and the screw 26 and the limiting action of the first ear plate 27 and the two limiting grooves 28, the screw 26, the first ear plate 27, the circular shaft 29, and the two arc-shaped grinding sheets 39 are driven to move synchronously, so as to adjust the position of the arc-shaped grinding sheet 39 to move to the cutting position.

[0040] The electric telescopic rod 37 is started to drive the second ear plate 36 to move. When the second ear plate 36 moves, under the connection of the two second connecting rods 38, the two multi-stage telescopic rods 40 and the two arc-shaped grinding sheets 39 are driven to move synchronously in opposite directions, so that the two arc-shaped grinding sheets 39 fit with the inner wall of the peripheral side of the cutting hole, thereby adapting to cutting holes of different diameters, and facilitating the grinding operation. After the arc-shaped grinding sheets 39 fit with the inner wall of the peripheral side of the cutting hole, the grinding motor 33 is started to drive the transmission gear 34 to rotate, thereby driving the matching gear 35, the circular shaft 29, and the two arc-shaped grinding sheets 39 to rotate synchronously through the meshing action, grinding the inner wall of the peripheral side of the cutting hole, thereby removing the oxide scale, making the surface smooth, and improving the corrosion resistance.

[0041] After the grinding is completed, the grinding motor 33 is turned off, and the second ear plate 36 and the two arc-shaped grinding sheets 39 are driven to reset through the electric telescopic rod 37, and the driving motor 24 is started to drive the screw guide sleeve 25 to move in the opposite direction, thereby driving the first ear plate 27, the circular shaft 29, and the two arc-shaped grinding sheets 39 to reset. During the rotation of the screw guide sleeve 25, the rotating shaft 30 is driven to rotate under the meshing action of the first driving gear 32 and the first driven gear 31. When the rotating shaft 30 rotates, the meshing action of the second driving gear 44 and the second driven gear 43 drives the annular plate 42 and the multiple cleaning brushes 46 to rotate, and the surfaces of the two arc-shaped grinding sheets 39 are cleaned by the multiple cleaning brushes 46 to remove foreign matter such as metal debris on the surfaces of the arc-shaped grinding sheets 39. There is no need for manual cleaning by the staff, which effectively improves the subsequent grinding effect, and during the rotation of the annular plate 42 and the multiple cleaning brushes 46, the foreign matter adhering to the cleaning brush 46 can be cleaned through the action of the self-cleaning shaft 48, which effectively improves the continuous cleaning ability of the cleaning brush 46.
