Description

Technical Field

[0001] The invention relates to the technical field of parts processing devices, in particular to a dual-circuit switching type automobile parts cutting device and a use method thereof. Background Art

[0002] Auto parts refer to the individual components that make up a car. They play a vital role in the performance, safety and reliability of the car. In order to adapt to the size and space requirements of different models, some parts need to be cut into specific shapes and sizes. In addition, during the manufacturing process, cutting can also be used to remove excess parts of parts to improve the precision and quality of parts. Sometimes, cutting can be used to repair or replace damaged parts.

[0003] In the prior art, some auto parts are tubular, and laser cutting machines are commonly used to cut tubular parts. If the light at the laser head of the laser cutting machine is not concentrated enough, the energy of the laser beam will be dispersed, resulting in a slower cutting speed, reduced cutting quality, or even failure to complete the cutting task. However, the laser head of the existing laser cutting machine is not provided with a component that can assist in concentrating the laser beam, which reduces the cutting efficiency.

[0004] Therefore, we propose a dual-circuit switching type automobile parts cutting device and a method of using the same to solve the above-mentioned problems. Summary of the invention

[0010] Preferably, two lifting assemblies are arranged on the top of the fixed base plate, and the lifting assemblies include a fixed seat, a slot is provided on the top of the fixed seat, a clamping plate is inserted inside the slot, a support plate is fixedly connected to the top of the clamping plate, a plurality of first ball grooves are provided on the inner wall of the support plate, first rotating balls are movably connected to the inner walls of the first ball grooves, and pipe fittings are placed on the inner wall of the support plate.

[0011] Preferably, a card slot is provided on one side of the slot away from each other, a touch panel is fixedly connected to one side of the card board away from each other, and each touch panel is respectively inserted in each card slot.

[0012] Preferably, the opposite sides of the fixed seat are fixedly connected with mounting sleeves, the inner walls of the two mounting sleeves are slidably connected with push plates, the outer surfaces of the two push plates are fixedly connected with pull rods, one ends of the two pull rods respectively pass through the two mounting sleeves to the outside, one ends of the two pull rods are fixedly connected with pull blocks, connecting springs are arranged between the outer surfaces of the two push plates and the inner walls of the two mounting sleeves, the two connecting springs are respectively arranged on the outside of the two pull rods, and the outer surfaces of the two push plates are in contact with the outer surfaces of the two touch plates respectively.

[0015] A method for using a dual-line switching type automobile parts cutting device comprises the following steps:

[0016] S1. Place the pipe fittings on two pallets, and start the two electric telescopic rods at the same time to shrink the two electric telescopic rods, thereby driving the connecting plate and the clamping plate to move downward until the pipe fittings are clamped. When the pipe fittings are fully clamped, the position of the pipe fittings cannot be rotated. When the pipe fittings are not fully clamped, the position of the pipe fittings can be adjusted during cutting.

[0017] S2. When replacing the pallet, press the two pull blocks at the same time, so that the two pull rods will push the two push plates inward, so that the touch plate is disengaged from the card slot. At this time, pull the card plate out of the slot to facilitate the replacement and disassembly of the pallet. By electrically connecting the electric telescopic rod, hydraulic rod, forward and reverse motor, and laser cutting machine body to the dual-line switch, it can automatically switch to the backup power supply when the main power supply fails, so as to achieve the benefit of continuous power supply;

[0018] S3. During the cutting process, the hydraulic rod is activated to drive the support plate to rise and fall. Since the structure of the reinforced support plate is triangular and stable, it can effectively prevent the support plate from tipping over during the lifting process. The lifting of the support plate can also drive the cutting assembly to rise and fall. During cutting, the bottom of the cutting machine head is the laser head, which will emit laser;

[0019] S4. When the laser is dispersed, the forward and reverse motors are started to drive the active gear to rotate, and the meshing connection between the active gear and the gear ring drives the gear ring to rotate. Since the threaded ring and the threaded groove on the inner wall of the gear ring are threadedly connected, the rotation of the gear ring can drive the threaded ring to rise and fall. The gear ring and the limit frame are connected by multiple connecting rods, thereby driving the limit frame to move up and down outside the cutting head. The position of the focusing tube is adjusted by the reinforcing rod. The further the focusing tube moves downward, the better the laser beam concentration effect is. The reflector can reflect the light emitted downward to the bottom to assist in beam concentration.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. During use, when the laser is dispersed, the forward and reverse motors are started to drive the active gear to rotate, and then the gear ring is driven to rotate. Since the threaded ring and the threaded groove on the inner wall of the gear ring are threadedly connected, the rotation of the gear ring can drive the threaded ring to rise and fall. The gear ring and the limit frame are connected by multiple connecting rods, so as to drive the limit frame to move up and down outside the cutting head. The position of the focusing tube is adjusted by the reinforcing rod. The further the focusing tube moves downward, the better the laser beam concentration effect is. The reflector can reflect the light emitted downward to the bottom to assist the beam concentration. The focusing tube and the reflector are made of high-temperature resistant ceramics.

[0022] 2. When in use, the electric telescopic rod, hydraulic rod, forward and reverse motor, and laser cutting machine body are electrically connected to the dual-line switch, so that it can automatically switch to the backup power supply when the main power fails, so as to achieve the benefit of continuous power supply. During the cutting process, the support plate can be driven up and down by starting the hydraulic rod, and the cutting assembly can also be driven up and down at the same time;

[0023] 3. When in use, by starting the two electric telescopic rods at the same time, the two electric telescopic rods are contracted, thereby driving the connecting plate and the clamping plate to move downward until the pipe is clamped. When it is fully clamped, the position of the pipe cannot be rotated, and the first rotating ball rotates flexibly inside the first ball groove, and the second rotating ball rotates flexibly inside the second ball groove. This makes it convenient to adjust the position of the pipe during cutting. The support plate is replaceable. When replacing, press the two pull blocks at the same time, thereby pressing the two pull rods inward at the same time. The two pull rods will push the two push plates inward, and the push plates contact the touch plates, so that the touch plates are disengaged from the inside of the card slot. At this time, pull the card plate out of the slot to facilitate the replacement and disassembly of the support plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] like Figure 1-3 As shown, the support assembly 3 includes a hydraulic rod 301, which is arranged on the top of the fixed base plate 6, and the top of the hydraulic rod 301 is fixedly connected to a bearing plate 302, and the top of the bearing plate 302 is fixedly connected to a support plate 304, and a plurality of reinforcing support plates 303 are fixedly connected between the outer surfaces of the support plate 304 and the bearing plate 302, and the top of the support plate 304 is fixedly connected to a mounting plate 305, and an auxiliary plate 401 is fixedly installed on the outer surface of the support plate 304. By starting the hydraulic rod 301, the hydraulic rod 301 is extended and retracted, thereby driving the support plate 304 to rise and fall. Since the structure of the reinforcing support plate 303 is triangular and stable, it can effectively prevent the support plate 304 from tipping over during the lifting process.

[0041] like Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, two lifting components 2 are arranged on the top of the fixed base plate 6, and the lifting components 2 include a fixed seat 206, a slot 205 is provided on the top of the fixed seat 206, a clamping plate 204 is inserted inside the slot 205, a support plate 201 is fixedly connected to the top of the clamping plate 204, a plurality of first ball grooves 203 are provided on the inner wall of the support plate 201, and the inner walls of the first ball grooves 203 are movably connected with first rotating balls 202, pipe fittings 8 are placed on the inner walls of the support plates 201, and the pipe fittings 8 are placed on the two support plates 201 for easy cutting, and the support plates 201 can be disassembled and assembled through the flexible engagement between the slot 205 and the clamping plate 204.

[0042] like Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, a card slot 213 is provided on the opposite side of the slot 205, and a touch panel 212 is fixedly connected to the opposite side of the card plate 204. Each touch panel 212 is respectively inserted into the interior of each card slot 213. By detaching the touch panel 212 from the interior of the card slot 213, the card plate 204 is pulled out from the slot 205, thereby facilitating the replacement and disassembly of the tray 201.

[0043] like Figure 1 , Figure 2 , Figure 8 and Fig. 9As shown, the opposite side of the fixed seat 206 is fixedly connected with a mounting sleeve 207, the inner walls of the two mounting sleeves 207 are slidably connected with push plates 211, the outer surfaces of the two push plates 211 are fixedly connected with pull rods 209, one end of the two pull rods 209 respectively penetrates the two mounting sleeves 207 to the outside, one end of the two pull rods 209 is fixedly connected with pull blocks 208, connecting springs 210 are arranged between the outer surfaces of the two push plates 211 and the inner walls of the two mounting sleeves 207, the two connecting springs 210 are respectively arranged on the outside of the two pull rods 209, the outer surfaces of the two push plates 211 are in contact with the outer surfaces of the two touch plates 212 respectively, when replacing, the two pull blocks 208 are pressed at the same time, thereby pressing the two pull rods 209 inward at the same time, the two pull rods 209 will push the two push plates 211 inward, and the push plates 211 contact the touch plates 212.

[0044] like Figure 1 , Figure 2 and Fig.10 As shown, a clamping assembly 1 is arranged on the top of one of the lifting assemblies 2. The clamping assembly 1 includes two electric telescopic rods 101. Both electric telescopic rods 101 are arranged on the top of the fixed base plate 6. By starting the two electric telescopic rods 101 at the same time, the two electric telescopic rods 101 are retracted.

[0045] like Figure 1 , Figure 2 and Fig.10 As shown, the top ends of the two electric telescopic rods 101 are fixedly connected with a connecting plate 102, and a clamping plate 103 is fixedly connected between the opposite sides of the two connecting plates 102. The inner wall of the clamping plate 103 is provided with a plurality of second ball grooves 104, and the inner wall of each second ball groove 104 is movably connected with a second rotating ball 105. The connecting plate 102 and the clamping plate 103 are driven downward by the electric telescopic rod 101 until the pipe 8 is clamped, and the second rotating ball 105 is flexibly rotated inside the second ball groove 104, so that the position of the pipe 8 can be adjusted during cutting.

[0046] In the present invention, when in use, first, the pipe fitting 8 is placed on the two supporting plates 201 for easy cutting, and the two electric telescopic rods 101 are started at the same time to make the two electric telescopic rods 101 contract, thereby driving the connecting plate 102 and the clamping plate 103 to move downward until the pipe fitting 8 is clamped. When it is fully clamped, the position of the pipe fitting 8 cannot be rotated. When it is not fully clamped, since the surface of the pipe fitting 8 is in contact with the plurality of first rotating balls 202 and the plurality of second rotating balls 105, the first rotating balls 202 can flexibly rotate inside the first ball groove 203, and the second rotating balls 105 can flexibly rotate inside the second ball groove 104, so it is convenient to adjust the position of the pipe fitting 8 when cutting. The supporting plate 201 is replaceable. When replacing, press The two pull blocks 208 simultaneously press the two pull rods 209 inwards, and the two pull rods 209 will push the two push plates 211 inwards, and the push plates 211 contact the touch plates 212, so that the touch plates 212 are disengaged from the inside of the card slots 213. At this time, the card plate 204 is pulled out from the slot 205, so as to facilitate the replacement and disassembly of the support plate 201. By electrically connecting the electric telescopic rod 101, the hydraulic rod 301, the forward and reverse motors 402, and the laser cutting machine body 501 to the dual-line switching switch 9, it is possible to automatically switch to the backup power supply when the main power supply fails, so as to achieve the benefit of continuous power supply. During the cutting process, by starting the hydraulic rod 301, the hydraulic rod 301 is extended and retracted, thereby driving the support plate 304 to rise and fall. Due to the strengthening of the support plate 303 The structure is triangular and stable, so the support plate 304 can be effectively prevented from tipping over during the lifting process. The lifting of the support plate 304 can also drive the cutting assembly 5 to lift. The laser cutting machine body 501 is an existing device. The internal structure and working principle are public technologies, which will not be described in detail here. During cutting, the bottom of the cutting machine head 503 is the laser head, which will emit laser. When the laser is dispersed, the forward and reverse motors 402 are started, and the output shafts of the forward and reverse motors 402 rotate, thereby driving the active gear 403 to rotate. Under the meshing connection between the active gear 403 and the gear ring 404, the gear ring 404 is driven to rotate, and the limit ring 411 is sleeved on the outside of the rotating plate 502, and the rotating plate 50 2 is fixed on the outside of the laser cutting machine body 501, so the gear ring 404 will not change its height when rotating. Since the threaded ring 409 and the threaded groove 410 on the inner wall of the gear ring 404 are threadedly connected, the rotation of the gear ring 404 can drive the threaded ring 409 to rise and fall. The gear ring 404 and the limit frame 407 are connected by multiple connecting rods 406, so as to drive the limit frame 407 to move up and down outside the cutting machine head 503. The position of the focusing tube 405 is driven by the reinforcing rod 408 to adjust the position. The further the focusing tube 405 moves downward, the better the laser beam concentration effect is. The reflector 413 can reflect the light emitted downward to the bottom to assist the beam concentration. The material of the focusing tube 405 and the reflector 413 is ceramic with high temperature resistance characteristics;

[0047] The dual-line switching switch 9 is a dual power switch, which has two incoming lines, one in front and one in the back, and one outgoing line, and the two are connected together to come out from here. The dual power switching is usually used for more important loads. It has two power supplies. When there is a problem with one line, it can automatically switch to the other line, which can greatly improve the stability of electricity use. The dual-line switching switch 9 can automatically switch to the backup power supply when the main power supply fails to ensure the continuous power supply of the power equipment.

[0048] The wiring diagram of the electric telescopic rod 101, the hydraulic rod 301, the forward and reverse motor 402, the laser cutting machine body 501 and the dual-circuit switching switch 9 in the present invention belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the electric telescopic rod 101, the hydraulic rod 301, the forward and reverse motor 402, the laser cutting machine body 501 and the dual-circuit switching switch 9 are no longer explained in detail.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

5. The dual-circuit switching type automobile parts cutting device according to claim 4, characterized in that: A clamping assembly (1) is arranged on the top of one of the lifting assemblies (2), and the clamping assembly (1) comprises two electric telescopic rods (101), and the two electric telescopic rods (101) are both arranged on the top of the fixed bottom plate (6).

6. The dual-circuit switching type automobile parts cutting device according to claim 5, characterized in that: The top ends of the two electric telescopic rods (101) are fixedly connected to a connecting plate (102), a clamping plate (103) is fixedly connected between opposite sides of the two connecting plates (102), a plurality of second ball grooves (104) are formed on the inner wall of the clamping plate (103), and a second rotating ball (105) is movably connected to the inner wall of each second ball groove (104).

7. A method for using a dual-line switching type automobile parts cutting device, characterized in that: The dual-line switching type automobile parts cutting device according to claim 6 is used, comprising the following steps: S1, placing the pipe fitting (8) on two support plates (201), and simultaneously starting the two electric telescopic rods (101) to cause the two electric telescopic rods (101) to contract, thereby driving the connecting plate (102) and the clamping plate (103) to move downward until the pipe fitting (8) is clamped. When the pipe fitting (8) is fully clamped, the position of the pipe fitting (8) cannot be rotated. When the pipe fitting (8) is not fully clamped, the position of the pipe fitting (8) can be adjusted during cutting. S2. When replacing the support plate (201), the two pull blocks (208) are pressed simultaneously, so that the two pull rods (209) push the two push plates (211) inward, so that the touch plate (212) is disengaged from the inside of the card slot (213). At this time, the card plate (204) is pulled out from the slot (205), so as to facilitate the replacement and disassembly of the support plate (201). By electrically connecting the electric telescopic rod (101), the hydraulic rod (301), the forward and reverse motors (402), and the laser cutting machine body (501) to the dual-line switching switch (9), it is possible to automatically switch to the backup power supply when the main power supply fails, thereby achieving the benefit of continuous power supply; S3, during the cutting process, the hydraulic rod (301) is activated to drive the support plate (304) to rise and fall. Since the structure of the reinforcing support plate (303) is triangular and stable, the support plate (304) can be effectively prevented from tipping over during the lifting process. The lifting of the support plate (304) can also drive the cutting assembly (5) to rise and fall. During cutting, the bottom of the cutting machine head (503) is the laser head, which emits laser light. S4. When the laser is dispersed, the forward and reverse motors (402) are started to drive the active gear (403) to rotate. Under the meshing connection between the active gear (403) and the gear ring (404), the gear ring (404) is further driven to rotate. Since the threaded ring (409) and the threaded groove (410) on the inner wall of the gear ring (404) are threadedly connected, the rotation of the gear ring (404) can drive the threaded ring (409) to rise and fall. The gear ring (404) and the limit frame (407) are connected by multiple connecting rods (406), thereby driving the limit frame (407) to move up and down outside the cutting machine head (503). The position of the focusing tube (405) is driven to be adjusted by the reinforcing rod (408). The further the focusing tube (405) moves downward, the better the laser beam concentration effect is. The reflector (413) can reflect the light emitted downward to the bottom to assist in beam concentration.
