Description

Technical Field

[0001] This invention relates to the technical field of intelligent cutting devices, and more particularly to a fully automatic cutting device and method for processing automobile fenders. Background Technology

[0002] A car fender is a body panel located above the wheels. It is mainly used to protect the car body, reduce wind resistance, and enhance the appearance. During the processing of car fenders, a cutting device is usually used to cut the sides of the fender to remove the burrs and maintain the smoothness and flatness of the fender.

[0003] Existing cutting devices employ various methods to cut fender parts. For example, a cutting device for processing new energy vehicle parts, disclosed in CN119035641A, relates to the field of automotive parts processing technology. It includes a first cutting mechanism, a second cutting mechanism, a third cutting mechanism, a drive frame, and a switch. The first cutting mechanism includes a first cutting blade and a first rotating shaft; the second cutting mechanism includes a second cutting blade and a second rotating shaft; the third cutting mechanism includes a third cutting blade and a third rotating shaft; and each of the three drive frames includes a baffle and four limit rods. Existing cutting devices typically use a fixed cutting disc to cut sheet metal. Since the cutting disc cannot be moved or rotated, it can only perform horizontal or vertical cutting, and cannot cut irregularly shaped sheet metal (such as fender parts). The cutting range is narrow. For example, the aforementioned prior art uses multiple cutting blades to cut automotive parts. Since the positions of multiple cutting blades cannot be adjusted, the cutting range is limited, and it cannot cut along the curved edge of the fender part. At the same time, the device cannot clean up the debris during cutting in real time, and the debris is easy to fall on the fender, affecting the cutting accuracy. It has certain limitations. Therefore, there is an urgent need to design a fully automated cutting device and method for processing automobile fenders to solve the above problems. Summary of the Invention

[0014] A fully automated cutting method for machining automobile fenders, and a fully automated cutting device for machining automobile fenders as described above, includes the following steps: S1.

S6. The purified clean gas is blown into the placement platform through the air blowing pipe to cool down the fender parts, cutting disc, and grinding disc.

[0015] This invention provides a fully automated cutting device and method for machining automobile fenders. It has the following advantages: 1. When cutting fender parts, this cutting device can flexibly adjust the cutting of the cutting disc through the cooperation of the universal joint and the drive rod without affecting the normal rotation of the cutting disc. It can effectively cut the arc edges and irregular corners of the fender. At the same time, with the lifting displacement module and hydraulic push rod, the height and horizontal position of the cutting disc can be adjusted to achieve multi-position cutting. In addition, with the grinding disc, the burr removal and surface grinding can be completed simultaneously during the cutting process to improve the surface smoothness of the fender.

[0016] 2.

At the same time, multiple compression spring rods can adjust the position of the fender parts in real time during cutting, so that it can adapt to the angle adjustment of the cutting plate, allowing the fender parts to better fit and contact the cutting plate, further improving the cutting accuracy.

[0017] 3. When cutting fender parts, this cutting device can remove the debris generated during cutting in real time through the adsorption tube, avoiding the accumulation of debris that affects the cutting effect. After purification and filtration, clean cold air can be blown to the fender parts and the cutting disc to achieve active heat dissipation of the cutting disc, which can effectively extend the service life of the cutting disc and protect the fender parts from thermal deformation and damage.

[0018] 4. When cutting fender parts, this cutting device can directly inject the adsorbed hot air and cutting debris into the purified water. This can not only purify and filter the debris, avoiding excessive oil on the debris and affecting the recycling effect, but also dissipate heat and cool the hot air, so that it can be quickly cooled when blown onto the cutting disc, resulting in better cutting effect.

[0019] In summary, this invention, through the cooperation of components such as the universal joint and the lifting displacement module, can achieve multi-angle synchronous cutting and grinding of the fender, effectively adapting to the irregular contours of different fenders. At the same time, it adopts a dual positioning method of electromagnetic adsorption and elastic extrusion, which effectively improves the stability of the fender during cutting. Furthermore, the circulation system of adsorption, purification and air cooling can simultaneously achieve chip removal and heat dissipation and cooling of the cutting area during cutting, resulting in better cutting effect.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Example 1: Refer to Figures 1-3 A fully automatic cutting device for processing automobile fenders includes a fender part 15 to be cut, which is mounted on a support box 1.

[0025] This cutting device also includes: The cutting unit is located on the side of the support box 1 and includes a lifting displacement module 4 located on the side of the support box 1 for controlling the lifting and lowering. The lifting displacement module 4 is equipped with a lifting component. The lifting displacement module 4 is prior art. It is equipped with a lifting motor and controls the lifting and lowering of the lifting component through the lifting motor. This part is prior art and will not be described in detail here.

[0026] The cutting unit is used to grind and cut the fender 15, and automatically adjusts the cutting angle according to the side curvature of the fender 15 to achieve fine cutting of irregularly shaped plates.

[0027] The support platform 3 is mounted on the support box 1, and a placement platform 7 is horizontally slidably mounted on it. The placement platform 7 is equipped with a positioning component for positioning the fender piece 15. The placement platform 7 can slide horizontally on the support platform 3, thereby driving the fender piece 15 on it to move and enabling it to be moved for cutting.

[0028] The processing unit is located inside the support box 1. The processing unit is used to adsorb and remove the cutting chips generated during cutting to avoid the accumulation of cutting chips affecting the cutting accuracy. At the same time, it can also purify and screen the cutting chips to avoid excessive oil on the chips, which would affect the recycling effect. It can also dissipate and cool the hot air so that it can be quickly cooled when blown onto the cutting disc 10, resulting in better cutting effect.

[0029] The support box 1 is equipped with a control panel 2 on its side. The control panel 2 is used to control the opening and closing and operation status of the cutting unit, positioning component and processing unit, so as to realize the automated cutting of the fender 15 and the intelligent automatic cutting of the fender 15.

[0030] Example 2: Refer to Figures 2-6 The difference between this embodiment and embodiment one is that: the lifting displacement module 4 is provided with a pushing component, the pushing component is provided with a cutting disk 10 for cutting the fender 15, and the cutting disk 10 is provided with a grinding disk 14 for grinding.

[0031] The pushing assembly includes a transverse pushing frame 5, which is fixedly installed on the lifting component. The lifting displacement module 4 is used to control the lifting of the lifting component to adjust the cutting position. The lifting displacement module 4 controls the lifting of the transverse pushing frame 5 by controlling the lifting of the lifting component, thereby adjusting the height position of the cutting disk 10 and the grinding disk 14 on the transverse pushing frame 5.

[0032] The pushing assembly is equipped with a cutting mechanism, which includes a hydraulic pushing rod 11 fixedly installed in the transverse pushing frame 5. A limit slider 12 is slidably installed in the transverse pushing frame 5, and the limit slider 12 is fixedly installed on the driving end of the hydraulic pushing rod 11. A drive motor 6 is fixedly installed on the lower part of the limit slider 12. When the hydraulic push rod 11 is started, it will drive the limit slider 12 to move, which in turn drives the drive motor 6 on it to move horizontally, thereby adjusting the position of the drive motor 6 and controlling the position of the cutting disc 10 and the grinding disc 14 on it, so that they are close to the fender 15 for cutting.

[0033] In a further embodiment, a drive motor 6 is fixedly installed on the lower part of the limiting slider 12, and a drive rod is fixedly installed on the drive end of the drive motor 6. A universal joint shaft 13 is provided on the drive rod. A cutting disk 10 for cutting the fender 15 is fixedly installed on the universal joint shaft 13, and a grinding disk 14 for grinding the fender 15 is provided on the cutting disk 10. The universal joint shaft 13 is used to adjust the angle position of the cutting disk 10 without affecting the normal rotation of the cutting disk 10, thereby realizing multi-angle cutting of the fender 15. The hydraulic push rod 11 pushes the limit slider 12 to slide horizontally along the transverse push frame 5, driving the drive motor 6, universal shaft 13 and cutting disc 10 to move horizontally synchronously until the edge of the cutting disc 10 contacts the profile to be cut on the fender 15, thus completing the precise adjustment of the cutting position.

[0034] When cutting, the drive motor 6 is started first to drive the drive rod to rotate. The drive rod transmits the rotational power to the cutting disk 10 through the universal joint 13. When the cutting disk 10 rotates, it will drive the grinding disk 14 outside it to rotate synchronously at high speed. If the area to be cut on the fender 15 is arc-shaped or irregularly shaped, the operator can adjust the angle of the universal joint 13 (which does not affect the transmission of rotational power) through the control panel 2 or manually, so that the cutting disk 10 fits the irregularly shaped contour of the fender 15. At this time, when the cutting disk 10 rotates, it will cut the fender 15. After cutting, the cutting disk 10 and the grinding disk 14 can be moved down synchronously through the lifting displacement module 4, so that the grinding disk 14 is pressed and fitted against the side of the fender 15 after cutting. At this time, when the grinding disk 14 rotates, it will grind the side of the fender 15 synchronously, improving the surface smoothness of the fender 15.

[0035] Example 3: Refer to Figures 1-3 as well as Figures 11-12 The difference between this embodiment and embodiment two is that the positioning component includes a support platform 25 fixedly installed in the placement platform 7, an electromagnetic positioning disk 28 for adsorbing and positioning the fender piece 15 is slidably installed on the support platform 25, and a plurality of compression spring rods 26 are fixedly installed on the support platform 25, and a compression roller shaft 27 for compressing the fender piece 15 is rotatably installed on each compression spring rod 26. When cutting the fender 15, first place the fender 15 on the electromagnetic positioning disk 28 on the support platform 25, and then start the electromagnetic positioning disk 28 to generate magnetic force to attract the fender 15, thus completing the attraction and positioning of the fender 15. After the fender 15 is positioned, its uncut rear part will be pressed and adhered to multiple extrusion rollers 27, and at this time, multiple extrusion spring rods 26 are in a relaxed state.

[0036] The drive assembly includes a servo motor 17 fixedly installed in the support box 1, and a drive roller 18 fixedly installed on the drive end of the servo motor 17. A one-way bearing 19 is provided on the drive roller 18, and the one-way bearing 19 cooperates with the forward rotation of the drive roller 18. A reciprocating screw 20 is provided on the one-way bearing 19, and a ball nut disc 21 is fitted on the reciprocating screw 20. A movable frame 22 is slidably installed on the lower part of the placement platform 7, and the movable frame 22 is fixedly installed on the ball nut disc 21. After the fender 15 is positioned, the servo motor 17 can be started to drive the drive roller 18 to rotate in the forward direction. When the drive roller 18 rotates in the forward direction, it will drive the one-way bearing 19 that is fitted on it to rotate. When the one-way bearing 19 rotates, it will drive the reciprocating screw 20 on it to rotate. When the reciprocating screw 20 rotates, it will drive the ball nut disc 21 that is fitted on it to move, so that the ball nut disc 21 moves back and forth on the reciprocating screw 20.

[0037] After positioning, the ball nut disc 21 moves forward, which will drive the placement table 7 to move synchronously through the moving frame 22. This will drive the fender 15 on the placement table 7 to the lower part of the cutting disc 10, and cutting can begin. After all the fender parts 15 have been cut, the ball bearing nut disc 21 moves forward to its maximum position and then moves in the opposite direction back to its original position. This causes the cut fender parts 15 on the placement table 7 to return to their original positions, allowing the fender parts 15 to be removed and the next fender part 15 to be placed, thus enabling automatic cutting of the next fender part 15 and effectively improving the cutting efficiency of the fender parts 15.

[0038] The cooperation between the reciprocating lead screw 20 and the ball nut disc 21 is existing technology. The specific principle is as follows: the reciprocating lead screw 20 is a form of three-dimensional cam pair. Its specific structure consists of two threaded grooves with the same pitch and opposite directions of rotation. The two ends of the lead screw are connected by a transition curve. By rotating the lead screw, the side of the helical groove pushes the balls located in the helical groove of the ball nut disc 21 to make axial reciprocating motion. The reciprocating motion of the balls will drive the ball nut disc 21 to move back and forth. That is, when the reciprocating lead screw 20 rotates in one direction, it can drive the ball nut disc 21 to make it move back and forth linearly on the reciprocating lead screw 20.

[0039] When the cutting disc 10 or grinding disc 14 cuts or grinds the fender 15, it applies an inward thrust to the fender 15 (see instruction manual). Figure 11 (in the direction from reference numeral 15 to reference numeral 25), thereby compressing and squeezing the spring rod 26, and thus applying stable pressure to the fender 15 through the squeezing action of the spring rod 26 and the cutting disc 10, further improving the cutting stability of the fender 15.

[0040] While the cutting disc 10 is cutting, when the cutting disc 10 deflects and presses against the arc-shaped side of the fender 15, the electromagnetic positioning disc 28 and the fender 15 will move inward as a whole. This allows the cutting disc 10 to fit more tightly against the side of the fender 15 without adjusting the overall position of the cutting disc 10, thereby further improving the cutting or grinding effect of the fender 15.

[0041] Example 4: Refer to Figures 7-9 as well as Figures 13-18 The difference between this embodiment and embodiment three is that the processing unit includes a driving component, a circulation component and a purification component. The driving component is used to control the horizontal movement of the placement platform 7 to realize the moving cutting of the fender 15. The circulation component is provided with an adsorption pipe 9 and an air blowing pipe 8. The adsorption pipe 9 is used to adsorb and process the cutting debris, and after being purified by the purification component, it is blown onto the fender 15 through the air blowing pipe 8 to realize the air blowing heat dissipation of the fender 15 during cutting.

[0042] The circulation assembly includes a storage box 16 fixedly installed in the support box 1. A driven roller 29 is rotatably installed in the storage box 16. A one-way bearing 30 is provided on the drive roller 18, and the one-way bearing 30 cooperates with the reverse rotation of the drive roller 18. A transmission belt 31 is sleeved between the driven roller 29 and the one-way bearing 30. A partition plate 32 is fixedly installed in the storage box 16. While cutting, the servo motor 17 will start and drive the drive roller 18 to reverse (at this time, the one-way bearing 19 does not rotate and the fender 15 does not move). The reverse rotation of the drive roller 18 will drive the one-way bearing 30 to rotate. When the one-way bearing 30 rotates, it will drive the driven roller 29 to rotate synchronously under the action of the transmission belt 31, thereby completing the transmission of the drive.

[0043] In a further embodiment, an adsorption mechanism is installed between the storage box 16 and the placement platform 7. The adsorption mechanism includes a fan impeller 33 fixedly installed on the driven roller 29, and the fan impeller 33 is located between the partition plate 32 and the side wall of the storage box 16. An air blowing hood 23 and an adsorption hood 24 are respectively provided on both sides of the placement platform 7. Two adsorption tubes 9 for adsorbing cutting impurities are fixedly connected between the adsorption hood 24 and the storage box 16. An air blowing pipe 8 for blowing purified gas is fixedly connected between the air blowing hood 23 and the storage box 16. Both adsorption tubes 9 and air blowing pipe 8 are elastic tubes. Multiple air inlet pipes 34 for conducting gas are provided on the partition plate 32. When the driven roller 29 rotates, it will drive the impeller 33 on it to rotate. When the impeller 33 rotates, it will generate negative pressure suction between the storage box 16 and the partition plate 32. The negative pressure suction acts on the two adsorption tubes 9 through the air inlet pipe 34, and then the negative pressure suction is generated through the adsorption cover 24. During the cutting process, the negative pressure suction generated by the adsorption hood 24 can simultaneously adsorb the cutting debris and hot air into the storage box 16 through the adsorption hood 24 and the two adsorption tubes 9, thus completing the collection of cutting debris and preventing the cutting debris from accumulating on the placement platform 7 and the fender 15 and affecting the cutting accuracy.

[0044] In a further embodiment, the purification component includes a support inclined plate 35 fixedly installed between the storage box 16 and the partition plate 32. The storage box 16 is filled with purified water at the lower part of the support inclined plate 35. A conduction pump 38 is provided at the bottom of the storage box 16, and a slugging pipe 40 for conducting purified water is provided on the discharge end of the conduction pump 38. The outlet end of the slugging pipe 40 is located at the upper part of the support inclined plate 35. As the cutting debris enters the storage box 16 (located above the bearing inclined plate 35), the conduction pump 38 starts to absorb purified water and sprays the purified water onto the upper part of the bearing inclined plate 35 through the condenser pipe 40. At this time, the purified water comes into contact with the cutting debris on the upper part of the bearing inclined plate 35 inside the storage box 16, thus purifying and adsorbing the cutting debris. The hot air cools down rapidly after contacting the water, and the debris is intercepted and settled by the purified water, thus completing the purification of the debris and the cooling of the hot air.

[0045] In a further embodiment, two swing frames 42 are fixedly installed on the partition plate 32, and swing elements 39 are rotatably installed on both swing frames 42. A pressing hook wheel 37 that cooperates with the two swing elements 39 is fixedly installed on the driven roller 29. A swing spring 43 for resetting is fixedly installed between each swing element 39 and the corresponding swing frame 42. When the driven roller 29 rotates, it drives the pressing hook wheel 37 on it to rotate synchronously. When the pressing hook wheel 37 rotates, it periodically presses the swing member 39. When the swing member 39 is squeezed, it moves down and stretches the swing spring 43. When the swing member 39 separates from the pressing hook wheel 37, the swing spring 43 automatically stretches and resets, and drives the swing member 39 to rebound, thereby realizing the reciprocating swing of the swing member 39. When the swing member 39 reciprocates, it will come into further contact with the cutting chips in the hot air, causing the cutting chips to fall off and improving the separation efficiency of the cutting chips. At the same time, the swing of the swing member 39, in conjunction with the rotation of the pressing hook wheel 37, can separate and disperse the purified water in the storage box 16, so that the purified water comes into closer contact with the hot air and cutting chips, further improving the efficiency of chip settling and the cooling efficiency of the hot air.

[0046] The cooled air will enter the air blowing hood 23 through the air intake pipe 34 and the air blowing pipe 8, and be blown onto the fender 15 and the cutting disc 10 in the placement table 7. This will provide efficient air blowing and cooling for the fender 15 and the cutting disc 10, and prevent overheating and deformation damage to the fender 15 and the cutting disc 10 during long-term cutting.

[0047] At the same time, the air blowing hood 23 can also blow cutting chips and hot air, making it easier for them to enter the adsorption hood 24, thus improving the adsorption efficiency of the adsorption hood 24. After the cutting is completed, the electromagnetic positioning disk 28 is de-energized and demagnetized, releasing its adsorption of cutting chips. At this time, the adsorption hood 24 continues to adsorb, which can remove the cutting chips adsorbed on the electromagnetic positioning disk 28 and prevent the cutting chips from accumulating on the electromagnetic positioning disk 28.

[0048] A screening box 36 is fixedly installed on the bearing inclined plate 35, and an electric opening and closing door 41 is provided on the upper part of the screening box 36, and a screening filter plate 44 for filtering impurities is provided on the lower part of the screening box 36. After cutting is completed, the electric door 41 on the screening box 36 can be opened by controlling the control panel 2, so that the purified water and debris on the bearing inclined plate 35 enter the screening box 36 at the same time. The screening filter plate 44 in the screening box 36 will filter the debris, leaving the debris and impurities on the screening filter plate 44, while the purified water permeates to the lower part of the bearing inclined plate 35 and flows back to the conduction pump 38, realizing the separation of debris and purified water, and at the same time completing the recycling of purified water.

[0049] Both the support box 1 and the storage box 16 are equipped with inspection ports, which allow for the inspection and replacement of the internal structure of the support box 1 and the storage box 16, as well as the collection and treatment of debris and purified water.

[0050] The specific working principle of this cutting device is as follows: When cutting the fender 15, the fender 15 is first placed on the electromagnetic positioning disk 28 on the support platform 25, and then the electromagnetic positioning disk 28 is activated to generate magnetic force to attract the fender 15, thus completing the attraction and positioning of the fender 15. After the fender piece 15 is positioned, the servo motor 17 can be started to drive the drive roller 18 to rotate in the forward direction. When the drive roller 18 rotates in the forward direction, it drives the one-way bearing 19 to rotate. The rotation of the one-way bearing 19 drives the reciprocating screw 20 to rotate, which in turn drives the ball nut plate 21 to move in the forward direction. Through the moving frame 22, it drives the placement table 7 to move synchronously, which can move the fender piece 15 on the placement table 7 to the lower part of the cutting disc 10 to complete the cutting preparation.

[0051] During cutting, the position of the cutting disc 10 is adjusted by the cooperation of the lifting displacement module 4 and the hydraulic push rod 11, so that the edge of the cutting disc 10 contacts the profile to be cut of the fender 15, thus completing the precise adjustment of the cutting position.

[0052] When cutting, the drive motor 6 is started first to drive the drive rod to rotate. The drive rod transmits the rotational power to the cutting disk 10 through the universal joint 13. When the cutting disk 10 rotates, it will drive the grinding disk 14 outside it to rotate synchronously at high speed. If the area to be cut on the fender 15 is arc-shaped or irregularly shaped, the operator can adjust the angle of the universal joint 13 via the control panel 2 or manually to make the cutting disk 10 fit the irregular contour of the fender 15. At this time, when the cutting disk 10 rotates, it will cut the fender 15. After cutting, the cutting disk 10 and the grinding disk 14 can be moved down synchronously through the lifting displacement module 4, so that the grinding disk 14 is pressed and fitted against the side of the fender 15 after cutting. At this time, when the grinding disk 14 rotates, it will grind the side of the fender 15 synchronously, improving the surface smoothness of the fender 15.

[0053] While cutting, the servo motor 17 will start and drive the drive roller 18 to reverse (at this time, the one-way bearing 19 does not rotate and the fender 15 does not move). The reverse rotation of the drive roller 18 will drive the one-way bearing 30 to rotate. When the one-way bearing 30 rotates, it will drive the driven roller 29 to rotate synchronously under the action of the transmission belt 31. When the driven roller 29 rotates, it will drive the impeller 33 on it to rotate. When the impeller 33 rotates, it will generate negative pressure suction between the storage box 16 and the partition plate 32. The negative pressure suction acts on the two adsorption tubes 9 through the air inlet pipe 34, and then the negative pressure suction is generated through the adsorption cover 24. During the cutting process, the negative pressure suction generated by the adsorption hood 24 can simultaneously adsorb the cutting debris and hot air into the storage box 16 through the adsorption hood 24 and the two adsorption tubes 9, thus completing the collection of cutting debris and preventing the cutting debris from accumulating on the placement platform 7 and the fender 15 and affecting the cutting accuracy.

[0054] As the cutting debris enters the storage box 16, the conduction pump 38 starts to absorb purified water and sprays the purified water onto the upper part of the support inclined plate 35 through the condenser pipe 40. At this time, the purified water comes into contact with the cutting debris on the upper part of the support inclined plate 35 inside the storage box 16, thus purifying and adsorbing the cutting debris. The hot air cools down rapidly after contacting the water, and the debris is intercepted by the purified water and settles down, completing the purification of the debris and the cooling of the hot air.

[0055] The cooled air will enter the air blowing hood 23 through the air intake pipe 34 and the air blowing pipe 8, and be blown onto the fender 15 and the cutting disc 10 in the placement table 7. This will provide efficient air blowing and cooling for the fender 15 and the cutting disc 10, and prevent overheating and deformation damage to the fender 15 and the cutting disc 10 during long-term cutting.

[0056] This invention also provides a fully automated cutting method for automobile fender machining, and a fully automated cutting device for automobile fender machining, comprising the following steps: S1. When cutting the fender 15, first place the fender 15 on the placement table 7 and position it using the positioning assembly. S2. Start the drive assembly to move the placement stage 7 to the lower part of the cutting disk 10; S3. Start the lifting displacement module 4 and the pushing component to adjust the height and horizontal position of the cutting disk 10 so that the cutting disk 10 contacts the fender 15. S4. Start the cutting assembly to drive the cutting disk 10 and grinding disk 14 to rotate, and cooperate with the squeezing action of the positioning assembly to perform comprehensive cutting and grinding on the fender 15. S5. During the cutting process, the circulation component is activated to adsorb cutting debris through the adsorption tube 9 and transfer the cutting debris to the purification component for purification and filtration. S6. The purified clean gas is blown into the placement table 7 through the air blowing pipe 8 to cool down the fender 15, the cutting disc 10, and the grinding disc 14.
