Technical Field

[0001] This invention relates to the field of automotive parts cutting device technology, specifically to an internal cutting device for automotive parts that prevents accidental contact. Background Technology

[0002] The automotive parts internal cutting device is a processing device capable of quickly removing burrs from the inner walls of automotive parts. This device uses a pressing mechanism to fix the automotive part onto a limiting base, and then uses the internal cutting device to cut the inner wall of the part to remove the burrs. A cutting collection device is used to collect waste generated during the cutting process, while the pressing mechanism is used to fix the automotive part, ensuring the accuracy and safety of the cutting process. In summary, the automotive parts internal cutting device is a highly efficient and precise automotive parts processing equipment that can help improve production efficiency and product quality.

[0003] In the current automotive parts manufacturing process, it is often necessary to cut and grind the inner walls of automotive parts. However, because the inner walls of automotive parts are relatively narrow, it is difficult for operators to accurately control the cutting tools during operation, which can easily lead to accidental contact with other areas, resulting in over-cutting of the inner side of the automotive parts and rendering the cut automotive parts unusable.

[0004] Therefore, we propose an internal cutting device for automotive parts that prevents accidental contact, in order to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an internal cutting device for automotive parts that prevents accidental contact, in order to solve the problem mentioned in the background art that the internal wall cutting of automotive parts is prone to accidental contact with non-cutting areas, resulting in parts not meeting the size requirements.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-accidental-touch automotive parts inner cutting device, comprising: a cutting table, a support frame fixed at the bottom of the cutting table, an anti-accidental-touch component, the anti-accidental-touch component comprising two fixed frames, a first forward and reverse motor provided on the inner top surface of each of the two fixed frames, a first threaded rod fixedly connected to the output shaft of each of the two first forward and reverse motors, a lifting block threadedly fitted on the outer surface of each of the two first threaded rods, an electromagnet fixed between the outer surfaces of the two lifting blocks, a limit post fixed on the top of the cutting table, a lifting rod movably embedded inside the limit post, and an iron disc fixed at the top end of the lifting rod.

[0007] Preferably, the bottom ends of the two first threaded rods are respectively movably embedded in the inner bottom surface of the two fixed frames. The outer surface of the limiting post has two grooves. The outer surface of each of the two grooves is provided with a positioning component. Each of the two positioning components includes a hollow frame. The outer surface of each of the two hollow frames is fixedly connected to the outer surface of the two grooves respectively.

[0008] Preferably, the bottoms of both hollow frames are fixedly connected to the top of the cutting table, and two mounting blocks are fixedly fixed on the outer surface of the lifting rod near the bottom. A drive motor is provided on the outer surface of each of the two mounting blocks, and a movable tube is fixedly connected to the output shaft of each of the two drive motors. A locking rod is fixedly installed at one end of each of the two movable tubes.

[0009] Preferably, the support frame is provided with a fixing component inside, the fixing component including a negative pressure pump, the outer surface of the negative pressure pump is fixedly connected to the inner wall of the support frame by screws, the outer surfaces of the air inlet pipe and air outlet pipe of the negative pressure pump are provided with valves, the inner walls of the support frame are fixedly installed with connecting plates, and a connecting ring is fixed between the outer surfaces of the two connecting plates.

[0010] Preferably, one end of the air inlet pipe and one end of the air outlet pipe of the negative pressure pump are fixedly inserted into the interior of the connecting ring, and the top of the connecting ring is fixedly connected to multiple connecting pipes, the top ends of the multiple connecting pipes being fixedly inserted into the exterior of the cutting table.

[0011] Preferably, a positioning plate is fixed inside the cutting table, and the top ends of the plurality of connecting tubes are fixedly inserted into the interior of the positioning plate, and suction cups are provided at the top ends of the plurality of connecting tubes.

[0012] Preferably, a cutting assembly is provided on the top of the cutting table, and the cutting assembly includes two load-bearing frames, the bottom of which is fixedly connected to the top of the cutting table.

[0013] Preferably, a second forward and reverse motor is provided on the inner wall of each of the two load-bearing frames, and the output shafts of the two second forward and reverse motors are fixedly connected to a second threaded rod, with one end of each second threaded rod extending movably through to the outside of the two load-bearing frames.

[0014] Preferably, the outer surfaces of both second threaded rods are threaded with sliding plates, and a third forward and reverse motor is provided on the outer surface of one of the sliding plates. The output shaft of the third forward and reverse motor is fixedly connected to a ball screw.

[0015] Preferably, one end of the ball screw extends movably through the outside of another slide plate, an electric actuator is provided on the outer surface of the ball screw, a load-bearing block is fixed at the bottom of the electric actuator, and a laser cutter is provided at the bottom of the load-bearing block.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. After the automotive parts are fixed, the two first forward and reverse motors are started, which drive the electromagnet to move upward, and then drive the iron disc to the edge of the position to be cut. When the third forward and reverse motor is started, it drives the laser cutter to the position corresponding to the inner wall of the automotive parts. The two second forward and reverse motors are started until the laser cutter moves to the top of the position to be cut. The electric push rod and the laser cutter are then started to cut the automotive parts. This solves the problem in the prior art that the inner wall of automotive parts is easily accidentally touched by non-cutting areas, resulting in the parts not meeting the size requirements.

[0017] 2. During the processing of automotive parts, when it is necessary to cut the inside of the automotive parts, first place the automotive parts to be cut on the top of the positioning plate, start the negative pressure pump, and open the valve on the surface of the air intake pipe, so that the contact surface between the multiple suction cups and the automotive parts is in a vacuum state, and finally fix the automotive parts on the surface of the positioning plate. Through the action of the fixing components, the automotive parts are effectively fixed, which facilitates the subsequent cutting of the automotive parts.

[0018] 3. When the iron disc moves to the edge of the position to be cut, start the two drive motors to drive the two clamping rods to rotate. When the clamping rods rotate to the position where they contact the inner wall of the hollow frame, the two ends of the clamping rods will be squeezed, which will cause the clamping rods to be stuck inside the hollow frame, thereby fixing the iron disc and effectively preventing the iron disc from moving.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-8 The present invention provides a technical solution: an anti-accidental touch cutting device for the inner side of automotive parts, comprising: a cutting table 1, a support frame 2 fixed at the bottom of the cutting table 1, an anti-accidental touch component 4, the anti-accidental touch component 4 comprising two fixed frames 401, a first forward and reverse motor 402 provided on the inner top surface of each of the two fixed frames 401, a first threaded rod 403 fixedly connected to the output shaft of each of the two first forward and reverse motors 402, a lifting block 404 threadedly sleeved on the outer surface of each of the two first threaded rods 403, an electromagnet 405 fixed between the outer surfaces of the two lifting blocks 404, a limit post 406 fixed at the top of the cutting table 1, a lifting rod 407 movably embedded inside the limit post 406, and an iron disc 408 fixed at the top of the lifting rod 407.

[0023] like Figure 1-2 and Figure 5-7As shown, the bottom ends of the two first threaded rods 403 are movably embedded in the inner bottom surfaces of the two fixed frames 401. The outer surface of the limiting post 406 has two grooves 5. The outer surface of each groove 5 is provided with a positioning component 6. Each positioning component 6 includes a hollow frame 601. The outer surfaces of the two hollow frames 601 are fixedly connected to the outer surfaces of the two grooves 5. By connecting the two first threaded rods 403 with the two fixed frames 401, the stability of the two first threaded rods 403 is ensured. The opening of the two grooves 5 allows the two mounting blocks 602 to move along the lifting rod 407. The movement of the iron disc 408 drives the lifting rod 407 to move upward, which in turn drives the mounting blocks 602 to move upward, thereby causing the clamping rod 605 to move upward until the iron disc 408 moves to the edge of the position to be cut.

[0024] like Figure 1-4 and Figure 6-7 As shown, the bottoms of both hollow frames 601 are fixedly connected to the top of the cutting table 1. Two mounting blocks 602 are fixed to the outer surface of the lifting rod 407 near the bottom. Each mounting block 602 has a drive motor 603 mounted on its outer surface. The output shafts of both drive motors 603 are fixedly connected to movable tubes 604. A locking rod 605 is fixedly mounted at one end of each movable tube 604. The connection between the two hollow frames 601 and the cutting table 1 ensures the stability of the two hollow frames 601. The lifting rod... The fixing between 407 and mounting block 602 allows the lifting rod 407 to move the two mounting blocks 602 during its movement, thereby activating the two drive motors 603 and causing the two locking rods 605 to rotate. The length of the locking rod 605 is greater than the internal width of the hollow frame 601. When the locking rod 605 rotates to the position where it contacts the inner wall of the hollow frame 601, both ends of the locking rod 605 will be squeezed, thereby causing the locking rod 605 to be locked inside the hollow frame 601, thus completing the fixing of the locking rod 605.

[0025] like Figure 1-4 As shown, a fixing component 3 is installed inside the support frame 2. The fixing component 3 includes a negative pressure pump 301. The outer surface of the negative pressure pump 301 is fixedly connected to the inner wall of the support frame 2 by screws. Valves 302 are installed on the outer surfaces of the air inlet pipe and the air outlet pipe of the negative pressure pump 301. Connecting plates 304 are fixedly installed on the opposite inner walls of the support frame 2. A connecting ring 303 is fixed between the outer surfaces of the two connecting plates 304. When the two ends of the two clamps 605 are separated from the inner walls of the two hollow frames 601 respectively, the iron disc 408 can move downward under its own gravity. Then the negative pressure pump 301 is restarted and the valve 302 on the surface of the air inlet pipe is opened to deliver gas into the interior of the connecting ring 303.

[0026] like Figure 1-4As shown, one end of the air inlet pipe and the air outlet pipe of the negative pressure pump 301 are fixedly inserted into the interior of the connecting ring 303. The top of the connecting ring 303 is fixedly connected to multiple connecting pipes 305, and the top ends of the multiple connecting pipes 305 are fixedly inserted into the exterior of the cutting table 1. By inserting the air inlet pipe and the air outlet pipe of the negative pressure pump 301 into the interior of the connecting ring 303, the gas delivery is facilitated. The negative pressure pump 301 is started and the valve 302 on the surface of the air inlet pipe is opened to draw out the gas inside the connecting ring 303, and then draw out the gas inside the multiple connecting pipes 305.

[0027] like Figure 1-4 As shown, a positioning plate 307 is fixed inside the cutting table 1. The top ends of multiple connecting pipes 305 are fixedly inserted into the interior of the positioning plate 307. Suction cups 306 are provided at the top ends of the multiple connecting pipes 305. When it is necessary to cut the inside of the automotive parts, the automotive parts to be cut are first placed on the top of the positioning plate 307, with the inner wall part to be cut facing upwards. The size of the automotive parts to be processed matches the size of the positioning plate 307. By inserting the connecting pipes 305 into the interior of the positioning plate 307, it is convenient to fix the automotive parts.

[0028] like Figure 1-4 and Figure 8 As shown, a cutting assembly 7 is provided on the top of the cutting table 1. The cutting assembly 7 includes two support frames 701. The bottom of the two support frames 701 is fixedly connected to the top of the cutting table 1. The cutting assembly 7 facilitates the cutting of the inside of automotive parts. The stability of the cutting assembly 7 is ensured by fixing the two support frames 701 to the cutting table 1.

[0029] like Figure 1-2 and Figure 8 As shown, a second forward and reverse motor 702 is provided on the inner wall of each of the two load-bearing frames 701. The output shafts of the two second forward and reverse motors 702 are fixedly connected to a second threaded rod 703. One end of each of the two threaded rods 703 extends movably through to the outside of the two load-bearing frames 701. When the two second forward and reverse motors 702 are started, the two threaded rods 703 are driven to rotate. By extending the two threaded rods 703 through to the outside of the two load-bearing frames 701, the stability of the two threaded rods 703 is ensured.

[0030] like Figure 1-8 As shown, the outer surfaces of the two second threaded rods 703 are threaded with sliding plates 704. A third forward and reverse motor 705 is installed on the outer surface of one of the sliding plates 704. The output shaft of the third forward and reverse motor 705 is fixedly connected to a ball screw 706. When the two second forward and reverse motors 702 are started, the two sliding plates 704 are moved along the direction of the second threaded rods 703. When the third forward and reverse motor 705 is started, the ball screw 706 is rotated.

[0031] like Figure 1-2 and Figure 8 As shown, one end of the ball screw 706 extends through the outside of another slide plate 704. An electric actuator 707 is installed on the outer surface of the ball screw 706. A load-bearing block 708 is fixed to the bottom of the electric actuator 707. A laser cutter 709 is installed at the bottom of the load-bearing block 708. By extending one end of the ball screw 706 through the outside of the slide plate 704, the stability of the ball screw 706 is ensured. When the laser cutter 709 moves to the top where it needs to be cut, the electric actuator 707 is activated, which drives the load-bearing block 708 to move downward, thereby driving the laser cutter 709 to move downward. The laser beam generated by the laser in the laser cutter 709 has high energy and high focusing. The beam is focused by a lens or mirror, concentrating the energy at a very small focal point to increase the energy density. The high-energy laser beam melts the surface of the workpiece to achieve the purpose of cutting the workpiece. When the laser cutter 709 moves to the position where it needs to be cut, the laser cutter 709 is activated, and the automotive parts can be cut.

[0032] The usage and working principle of this device are as follows: During the processing of automotive parts, when it is necessary to cut the inner side of an automotive part, first place the automotive part to be cut on top of the positioning plate 307, with the inner wall portion to be cut facing upwards. The size of the automotive part to be processed must match the size of the positioning plate 307. Figure 3As shown, the suction cup 306 in the positioning plate 307 has a small diameter, corresponding to the solid part of the car part. The iron disc 408 is positioned at the hollow part of the car part, and the outer diameter of the iron disc 408 matches the inner diameter of the car part. Then, the negative pressure pump 301 is started, and the valve 302 on the surface of the air intake pipe is opened to suck out the gas inside the connecting ring 303, thereby sucking out the gas inside the multiple connecting pipes 305. This creates a vacuum between the multiple suction cups 306 and the contact surface of the car part, ultimately fixing the car part to the surface of the positioning plate 307. Through the action of the fixing component 3, the car part is effectively fixed, facilitating the subsequent cutting of the car part. After the car part is fixed, the two first forward and reverse motors 402 are started. The two first threaded rods 403 rotate, thereby causing the two lifting blocks 404 to move upward. The movement of the two lifting blocks 404 causes the electromagnet 405 to move upward. At the same time, the electromagnet 405 is electrically connected to an external power source, so that it generates a magnetic field, attracting the iron disc 408. Under the action of magnetic force, the iron disc 408 moves upward with the electromagnet 405. The automotive part to be cut is made of aluminum alloy. The movement of the electromagnet 405 causes the iron disc 408 to move upward. The movement of the iron disc 408 causes the lifting rod 407 to move upward, which in turn causes the mounting block 602 to move upward, thus causing the clamping rod 605 to move upward. When the iron disc 408 moves to the edge of the position to be cut, the two drive motors 603 are started, causing the two clamping rods 605 to rotate. The movement involves a clamping rod 605 whose length is greater than the internal width of the hollow frame 601. When the clamping rod 605 rotates to a position where it contacts the inner wall of the hollow frame 601, both ends of the clamping rod 605 are compressed, causing it to lock into the interior of the hollow frame 601, thus fixing the clamping rod 605. This, in turn, fixes the mounting block 602 inside the hollow frame 601, thereby fixing the lifting rod 407 and the iron disc 408. Then, the electromagnet 405 is disconnected from the external power supply, thus fixing the iron disc 408. Next, the third forward and reverse motor 705 is started, driving the ball screw 706 to rotate, which in turn drives the electric push rod 707 to move along the ball screw 706. The ball screw 706 is a type of... This device converts rotary motion into linear motion. Its working principle involves embedding a nut into a threaded screw. Many balls are embedded inside the nut. When the screw rotates, the balls roll, pushing the nut linearly along the screw. This design significantly reduces frictional resistance, improves transmission efficiency, and can withstand large axial loads. When the laser cutting machine 709 moves to the position corresponding to the inner wall of the automotive part, the third forward / reverse motor 705 is turned off, and the two second forward / reverse motors 702 are started. This drives the two second threaded rods 703 to rotate, thereby causing the two sliding plates 704 to move along the direction of the second threaded rods 703, and further driving the laser cutting machine 709 to move until it reaches the top to be cut.The electric actuator 707 can be activated to extend it, causing the load-bearing block 708 to move downwards, thereby moving the laser cutting machine 709 downwards. The laser beam generated by the laser in the laser cutting machine 709 has high energy and high focusing capability. The beam is focused through a lens or mirror, concentrating the energy at a very small focal point, increasing the energy density. The high-energy laser beam melts the workpiece surface, achieving the purpose of cutting the workpiece. When the laser cutting machine 709 moves to the desired cutting position, it is activated to cut the automotive parts. During the cutting process, due to the obstruction of the iron disc 408, the laser cutting machine 709 can only cut within a certain range, avoiding contact with areas below the iron disc 408. This solves the problem in existing technologies where the inner wall of automotive parts is easily cut into non-cutting areas. The problem of substandard part dimensions caused by the cutting process is addressed by restarting the two drive motors 603 after the automotive parts are cut. This causes the two clamping rods 605 to rotate in opposite directions. The drive motors 603 can rotate the movable tube 604 clockwise or counterclockwise and have a self-locking function, a mature technology that will not be elaborated upon here. When the ends of the two clamping rods 605 separate from the inner walls of the two hollow frames 601, the iron disc 408 moves downwards under its own weight. Then, the negative pressure pump 301 is restarted, and the valve 302 on the surface of the air intake pipe is opened, supplying gas into the connecting ring 303. This gas then supplies gas into the connecting tube 305 and the suction cups 306, causing the suction cups 306 to separate from the automotive parts, allowing the cut automotive parts to be removed.

[0033] The wiring diagrams of the negative pressure pump 301, the first forward and reverse motor 402, the electromagnet 405, the drive motor 603, the second forward and reverse motor 702, the third forward and reverse motor 705, the electric actuator 707, and the laser cutter 709 in this invention are common knowledge in the field, and their working principles are well-known technologies. The appropriate models are selected according to actual use. Therefore, the control methods and wiring arrangements of the negative pressure pump 301, the first forward and reverse motor 402, the electromagnet 405, the drive motor 603, the second forward and reverse motor 702, the third forward and reverse motor 705, the electric actuator 707, and the laser cutter 709 will not be explained in detail.

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