Description

Technical Field

[0001] The invention relates to the field of laser cutting, in particular to a laser cutting device for processing a switch. Background Art

[0002] A high-power density laser beam is used to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporates to form holes. As the beam moves across the material, the holes continuously form narrow slits to complete the cutting of the material. Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, so that the irradiated material quickly melts, vaporizes, ablates or reaches the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece. Laser cutting is one of the thermal cutting methods. Most laser cutting machines are controlled and operated by CNC programs or made into cutting robots. As a precision processing method, laser cutting can cut almost all materials, including two-dimensional or three-dimensional cutting of thin metal plates.

[0003] Since the metal plates are relatively thin, laser cutting can cut through thicker metal plates, so multiple layers of metal plates can be stacked together and processed by laser cutting. However, when the existing laser cutting device clamps the multiple layers of metal plates up and down, the clamping force in the middle position of the multiple layers of metal plates is small, which may cause the middle layer of metal plate to shift, resulting in processing errors.

[0023] 2. The laser cutting device used for processing the switch uses air to squeeze the piston disc to slide downward, so that the piston disc contacts the spring sheet. Since the air can be compressed, when the air pressure inside the extrusion cone is greater than the elastic force at the spring sheet, the piston disc will squeeze the spring sheet to deform, so that the high-pressure air quickly pushes the piston disc and the extrusion cone to hit the metal plate, thus forming a groove on the metal plate, so that the friction block on the outer surface of the second airbag can be snapped into the groove, thereby increasing the clamping friction.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in 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 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.

[0032] Example 1

[0033] See also Figure 1-2 A laser cutting device for processing a switch comprises a processing frame 1 and a laser cutting head 2 mounted at one end of the processing frame 1. Two clamping plates 6 are mounted inside the processing frame 1. A tidying device 8 is mounted at the lower end of the clamping plate 6. Two squeezing devices 7 are mounted at one end of the clamping plate 6. The squeezing device 7 is used to squeeze the steel plate to deform. The squeezing device 7 comprises a rotating shaft 71 rotatably connected to one end of the clamping plate 6. An arc plate 72 is mounted at one end of the rotating shaft 71. A protruding plate 74 is mounted at the other end of the rotating shaft 71. A first airbag 73 is mounted on the clamping plate 6. The first airbag 73 is used to abut against the protruding plate 74 after expansion.

[0034] There are several arranging devices 8, and the arranging devices 8 include a rotating rod 81 installed at the lower end of the clamping plate 6, and a first supporting plate 82 is installed at one end of the rotating rod 81;

[0035] Two first electric push rods 3 are also installed inside the processing frame 1. The two first electric push rods 3 are arranged opposite to each other. A connecting block 4 is installed at one end of the first electric push rod 3, and a second electric push rod 5 is installed at one end of the connecting block 4. The lower end of the second electric push rod 5 is connected to the upper end of the clamping plate 6.

[0036] according to Figure 1 As shown, several metal plates are placed between two clamping plates 6, and then the first electric push rod 3 pushes the connecting block 4 and the clamping plate 6 to move, and the two clamping plates 6 are used to clamp the two ends of the metal plates. Figure 2 As shown, air is filled into the two first airbags 73 by an air pump to expand the first airbags 73, and the expanded first airbags 73 are used to abut against the extended plate 74, and the extended plate 74 uses the rotating shaft 71 as a fulcrum to drive the arc plate 72 to move. The two arc plates 72 are relatively moved up and down to abut against the metal plate, and the arc size of the upper arc plate 72 is larger than that of the lower arc plate 72, so that the two sides of the metal plate will be tilted upward, so that the cross-section of several metal plates is a concave arc, and then the clamp is pulled by the second electric push rod 5. The plate 6 slides upward, and drives the rotating rod 81 and the first supporting plate 82 to slide out of the interior of the laser cutting head 2 through the clamping plate 6, and drives a plurality of arc-shaped concave metal plates to be lifted upward through the two clamping plates 6, and then continues to fill the first air bag 73 at the lower end with air, so that the arc plate 72 at the lower end continues to rotate, thereby causing the arc plate 72 to gradually move from the contact surface of the metal plate at the bottom layer to the contact surface of the second-to-last metal plate, thereby causing the metal plate at the bottom layer to fall to the upper end of the first supporting plate 82, so that the first supporting plate 82 is used to receive the metal plate, according to Figure 2 As shown, since there are a plurality of first support plates 82, after the first support plate 82 of the bottom layer receives the metal plate, the first support plate 82 of the second-to-last layer rotates, so that the first support plate 82 of the second-to-last layer rotates to the upper end of the first support plate 82 of the first-to-last layer, so that the first support plate 82 of the second-to-last layer can receive the next metal plate, and as the arc plate 72 continues to rotate, the metal plate continues to fall downward to the first support plate 82 of each layer, so that each metal plate is clamped, and the clamping effect is improved;

[0037] Further, after the plurality of metal plates are distributed on the upper ends of the plurality of first support plates 82, the first electric push rod 3 continues to slide the connecting block 4 and the clamping plate 6 toward one end, thereby clamping the metal plates through the first support plates 82 on both sides.

[0038] Example 2

[0039] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-3The finishing device 8 also includes a circular sleeve 83 rotatably connected to the inside of the clamping plate 6, the inner wall of the circular sleeve 83 is provided with a spiral groove 84, the inside of the circular sleeve 83 is slidably connected with a rotating rod 81, one end of the rotating rod 81 is installed with a slider 85, the slider 85 is slidably connected to the spiral groove 84, and the rotating rod 81 is connected to the clamping plate 6 through a second spring 87;

[0040] A square column 86 is also slidably connected inside the circular sleeve 83. The square column 86 passes through the upper end of the circular sleeve 83. A second support plate 88 is installed on the upper end of the square column 86.

[0041] The upper end of the second supporting plate 88 is also rotatably connected to a rotating rod 81 of another arranging device 8 .

[0042] according to Figure 3 As shown, the first support plate 82 of the last sorting device 8 at the lower end of the clamping plate 6 is initially extended, so when the first metal plate falls down, the first metal plate will fall to the upper end of the first support plate 82 of the last sorting device 8. Due to the high quality of the metal plate, the metal plate will press the first support plate 82 downward to slide downward, and the first support plate 82 drives the rotating rod 81 to slide downward, and the rotating rod 81 drives the slider 85 to slide and connect at the spiral groove 84, thereby causing the circular sleeve 83 to rotate, the circular sleeve 83 drives the square column 86 to rotate, and the square column 86 drives the second support plate 88 to rotate, so that the second support plate 88 can receive the second metal plate;

[0043] It should be noted that when the square column 86 drives the second support plate 88 to rotate, the rotating rod 81 at the upper end of the second support plate 88 is rotatably connected to the upper end of the second support plate 88, so when the second support plate 88 rotates, the second support plate 88 will not drive the upper end rotating rod 81 to rotate;

[0044] Subsequently, when the second support plate 88 receives the second metal plate, the second support plate 88 is squeezed downward by the second metal plate, and the second support plate 88 pulls the rotating rod 81 of the second sorting device 8 at the upper end to slide downward, and the rotating rod 81 of the second sorting device 8 drives the slider 85 to slide downward, so that the circular sleeve 83 of the second sorting device 8 rotates, and the rotation of the second circular sleeve 83 drives the square column 86 of the second sorting device 8 and the second support plate 88 to rotate, so that the third metal plate can be received, and this cycle is repeated to receive several metal plates, thereby improving the clamping effect.

[0045] Example 3

[0046] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-4 , a clamping device 9 is installed at the lower end of the second support plate 88 and the upper end of the first support plate 82, and the clamping device 9 is used to clamp the metal plate;

[0047] The clamping device 9 includes a second air bag 93 installed on the upper end of the second support plate 88 and the upper end of the first support plate 82 .

[0048] according to Figure 4 As shown, when the metal plate is located between the second support plate 88 and the first support plate 82, air is filled into the second airbag 93 to expand the second airbag 93, and the two expanded second airbags 93 are used to clamp the upper and lower surfaces of the metal plate, thereby increasing the clamping area using the second airbags 93, thereby improving the clamping effect.

[0049] Example 4

[0050] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-6 The second air bag 93 is also provided with an air cylinder 95, the interior of the air cylinder 95 is slidably connected with a piston plate 96, and an extrusion cone 98 is provided at the lower end of the piston plate 96. The extrusion cone 98 penetrates the air cylinder 95 and the second air bag 93, and the extrusion cone 98 is connected to the air cylinder 95 via a third spring 99;

[0051] A friction block 90 is installed on the outer surface of the second airbag 93, and the friction block 90 is used to abut against the metal plate;

[0052] A transmission groove 15 is provided on one side of one of the second air bags 93, and a through groove is provided on one side of the air cylinder 95, and the through groove, the air cylinder 95 and the transmission groove 15 are connected;

[0053] A hose 94 is provided between the two second air bags 93;

[0054] A liquid storage chamber 10 is provided inside the connecting block 4, a push plate 12 is slidably connected inside the liquid storage chamber 10, the push plate 12 is connected to the connecting block 4 via a first spring 13, and a slide rod 11 is installed at the lower end of the push plate 12;

[0055] A transmission tube 14 is installed at one end of the connecting block 4, one end of the transmission tube 14 is connected to the inside of the liquid storage chamber 10, and the other end of the transmission tube 14 is connected to the inside of the clamping plate 6. A transmission groove 15 is provided on one side of the second support plate 88, and one end of the transmission tube 14 is used to be connected to one side of the transmission groove 15;

[0056] The inner wall of the gas cylinder 95 is provided with a spring piece 97 , and the piston plate 96 is used to abut against the spring piece 97 ;

[0057] The clamping device 9 further includes a bottom plate 92 mounted on the lower end of the second airbag 93 , and a piston rod 91 is mounted on one end of the bottom plate 92 .

[0058] according to Figure 2As shown in FIG. 1 , when the second electric push rod 5 drives the clamping plate 6 to slide upward, the clamping plate 6 will contact the slide bar 11, and the slide bar 11 drives the push plate 12 to slide and connect inside the liquid storage chamber 10, and the push plate 12 squeezes the air in the liquid storage chamber 10 so that the air enters the transmission pipe 14. Figure 4 As shown, when the second support plate 88 rotates, the transmission slot 15 at one end of the second support plate 88 is connected to the transmission tube 14 at the clamping plate 6, so that the transmission tube 14 transmits air to the transmission slot 15, and the transmission slot 15 transmits air to one of the second airbags 93 to expand the first second airbag 93. Since the two second airbags 93 are connected by a hose 94, the air discharged from the transmission slot 15 inflates the two second airbags 93 through the hose 94, so that the two second airbags 93 are expanded to clamp the metal plate;

[0059] The specific clamping state is as follows: Figure 6 As shown, when the second airbag 93 is inflated, the air inside the second airbag 93 will enter the inside of the air cylinder 95, so that the air is used to squeeze the piston plate 96 to slide downward, so that the piston plate 96 is against the spring plate 97. Since the air can be compressed, when the air pressure inside the extrusion cone 98 is greater than the elastic force at the spring plate 97, the piston plate 96 will squeeze the spring plate 97 to deform, so that the high-pressure air quickly pushes the piston plate 96 and the extrusion cone 98 to hit the metal plate, so that a groove is formed on the metal plate, so that the friction block 90 on the outer surface of the second airbag 93 can be buckled on the groove, thereby increasing the clamping friction.

[0060] It should be noted that the thickness of the switch casing iron sheet is 0.5 mm, so the high pressure pushing the extrusion cone 98 can leave a pit on the iron sheet.

[0061] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
