Description

Technical Field

[0001] This invention belongs to the field of automotive casting processing technology, specifically a deburring and cutting device for automotive castings. Background Technology

[0002] Automotive castings are metal parts produced through casting processes in automobile manufacturing. They are mainly used in key parts such as the body, engine, and chassis. The deburring and cutting process during the production of automotive castings is crucial in automobile manufacturing. It is mainly used to remove burrs, flash, and other excess material from the surface of the castings to ensure the precision and quality of the castings.

[0003] A patent application with publication number CN116748602A discloses a deburring device for automotive lock cylinder castings, including a frame, a clamping mechanism, a proximity drive mechanism, a keyhole pusher, and a through-hole pusher. The clamping mechanism is mounted on the frame, and the keyhole of the lock cylinder is mounted downwards in the clamping mechanism. The proximity drive mechanism has a first mounting component and a second mounting component that can approach the lock cylinder sequentially. This application mainly uses the drive mechanism to drive two pushers to deburr the keyhole and the pushers of the lock cylinder in sequence, which can improve the deburring efficiency.

[0004] In the deburring and cutting process of automotive castings, although the aforementioned deburring equipment can use two push cutters to accelerate the deburring efficiency, automotive castings have diverse and complex shapes, with their outer and inner walls exhibiting various angles. Due to the different angles of these angles, traditional equipment often has to use only a single cutting method and tool when dealing with these complex angles, making it difficult to adapt to the challenges of different angle combinations. This makes it difficult for existing equipment to effectively cut when deburring, and it can usually only handle standard workpieces and limited shapes, failing to meet the increasingly complex needs of modern automotive castings.

Detailed Implementation

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1 to 3 , Figure 6 As shown in the embodiment of the present invention, a deburring and cutting device for automotive castings includes a device frame 1; a first rotating roller 11 is rotatably connected to one outer wall of the device frame 1, and a first friction damper is provided between the device frame 1 and the first rotating roller 11; a first connecting plate 12 is fixedly connected to the end of the first rotating roller 11 away from the device frame 1; a first knob 13 is fixedly connected to the end of the first rotating roller 11 away from the first connecting plate 12; a first scraper blade 14 is fixedly connected to the outer walls of both the device frame 1 and the first connecting plate 12; during the deburring and cutting of automotive castings, according to the different included angles of different automotive castings, turning the first knob 13 drives the first rotating roller 11 to rotate, and the first connecting plate 12 rotates accordingly to cooperate with the device frame 1 to form a fit with the automotive casting. The included angle is limited by the first friction damper, which limits the included angle formed by the device frame 1 and the first connecting plate 12. The first friction damper is mainly used to limit the rotation of the first roller 11 after the angle is adjusted. The first scraper blade 14 on the device frame 1 is attached to one side of the included angle of the automobile casting, and the other scraper blade 14 on the first connecting plate 12 is attached to the other side of the included angle of the automobile casting. The device frame 1 and the first connecting plate 12 can be adaptively adjusted to be suitable for deburring and cutting automobile castings with acute angles, right angles and obtuse angles. The pushing device frame 1 slides on the surface of the automobile casting, and the two scraper blades 14 can deburr and scrape the included angle of the automobile casting. Finally, the deepest part of the included angle is ground and deburred using a special tool. It can effectively cut the burrs at different angles of the automobile casting.

[0032] The first scraper blade 14 has a triangular groove; an electric push rod 2 is fixedly connected to the outer wall of the device frame 1 on the side away from the first scraper blade 14, and the output end of the electric push rod 2 is fixedly connected to the outer wall of the device frame 1; a mounting plate 21 is fixedly connected to the end of the electric push rod 2 away from the device frame 1; when deburring the automotive casting at different angles, the mounting plate 21 is connected to the mobile device, and after adjusting the angle of the device frame 1 and the first connecting plate 12 for scraping the burrs, the output end of the electric push rod 2 extends, and drives the two first scraper blades 14 to push against the angle of the automotive casting first, from one end of the automotive casting to the other end. Then the output end of the electric push rod 2 retracts, and the triangular grooves on the two first scraper blades 14 scrape the surface of the automotive casting a second time, improving the deburring effect on the surface of the automotive casting.

[0033] like Figures 1 to 4 , Figure 6 As shown, a first electric slider 3 is slidably connected to the inner wall of the device frame 1; a sliding plate 31 is fixedly connected to the outer wall of the first electric slider 3, and the sliding plate 31 is slidably connected to the inner wall of the device frame 1; a connecting rod 32 is fixedly connected to the sliding plate 31; a second scraper blade 33 is fixedly connected to the end of the connecting rod 32 away from the sliding plate 31, and the second scraper blade 33 has a triangular oblique groove; when the first scraper blade 14 on the device frame 1 scrapes one side surface of the automotive casting, the first electric slider 3... The operation causes the sliding plate 31 to slide, and the connecting rod 32 subsequently drives the connected second scraper blade 33 to slide out of the inner wall of the device frame 1. This allows the first scraper blade 14 and the second scraper blade 33 to work together to scrape away burrs from the surface of longer automotive castings. When the triangular groove on the second scraper blade 33 is reset at the output end of the electric push rod 2, it performs a secondary scraping on the surface of the automotive casting. This allows the length of burrs removed at the device frame 1 to be adjusted according to the angle of the different lengths of the automotive casting, thus improving the applicability of the deburring and cutting device.

[0034] like Figures 1 to 3 , Figure 5 , Figure 6As shown, a second electric slider 4 is slidably connected to the inner wall of the first connecting plate 12; a first fixing plate 41 is fixed to the outer wall of the second electric slider 4; a third scraper 42 is fixed to one side of the first fixing plate 41, and a triangular groove is provided on the third scraper 42; when the first scraper 14 on the first connecting plate 12 scrapes one side of the automotive casting, the second electric slider 4 drives the first fixing plate 41 to slide, and the third scraper 42 slides out of the inner wall of the first connecting plate 12 at the same time, so that the first scraper 14 on the first connecting plate 12 and the third scraper 42 cooperate to push away burrs on the longer surface of the automotive casting, and cooperate with the triangular groove on the third scraper 42 to scrape the surface of the automotive casting a second time. The length of burr removal at the first connecting plate 12 can be adjusted according to the angle of different lengths of the automotive casting, further improving the applicability of the deburring and cutting device.

[0035] like Figures 1 to 4 , Figure 6 As shown, a second rotating roller 5 is rotatably connected to the sliding plate 31, and a second friction damper is provided between the second rotating roller 5 and the sliding plate 31; a second connecting plate 51 is fixedly connected to the end of the second rotating roller 5 away from the sliding plate 31, and a first scraper blade 14 is fixedly connected to the second connecting plate 51; a second knob 52 is fixedly connected to the end of the second rotating roller 5 away from the second connecting plate 51; when deburring and cutting the corner of the gate-shaped automotive casting, the second rotating roller 5 is turned by the second knob 52, which drives the second connecting plate 51 to rotate. The second connecting plate 51, which was originally retracted below the device frame 1, rotates and fits against one side surface of the automotive casting. The three first scraper blades 14 are respectively attached to the surface of the automotive casting that needs to be deburred. The second friction damper is limited after the second rotating roller 5 is rotated and adjusted. As the deburring and cutting device is pushed, the three first scraper blades 14 push and scrape the burrs on the included angle of the gate-shaped automotive casting. At the same time, the second connecting plate 51 can be adjusted and adapted at will according to the included angle of different automotive castings, so as to achieve the function of deburring the automotive casting on three sides.

[0036] like Figures 1 to 6As shown, a second fixing plate 6 is fixedly connected to the end of the second scraper blade 33 away from the connecting rod 32; a whetstone 61 is fixedly connected to both the second fixing plate 6 and the first fixing plate 41, and the whetstone 61 is attached to the outer wall of the first scraper blade 14; when the blades of the two first scraper blades 14 on the device frame 1 and the first connecting plate 12 have been scraping burrs for a long time, some burr debris easily adheres to the blades of the two first scraper blades 14, and the first electric slide is used to remove the debris. As block 3 and the second electric slider 4 drive the second scraper blade 33 and the third scraper blade 42 to slide, the two whetstones 61 on the second fixing plate 6 and the first fixing plate 41 respectively grind the blade edges of the two first scraper blades 14, improving the burr removal effect of the two first scraper blades 14. At the same time, the two whetstones 61 can also scrape off the waste at the blade edges of the two first scraper blades 14, reducing the adhesion of burrs on the two first scraper blades 14.

[0037] like Figures 1 to 4 , Figure 6 , Figure 7 , Figure 8 As shown, a fixed base 7 is fixedly connected to the side of the second connecting plate 51 near the electric push rod 2; an air inlet pipe 71 and an air outlet pipe 72 are fixedly connected to the fixed base 7 respectively; a first diversion box 73 is fixedly connected to the end of the air outlet pipe 72 away from the fixed base 7; a first corrugated pipe 74 is fixedly connected to the bottom end of the first diversion box 73; a first air deflector 75 is fixedly connected to the bottom end of the first corrugated pipe 74; after deburring and cutting the surface of the automotive casting, a large number of burrs are scraped off by the first scraper blade 14. The position of the first air deflector 75 is first adjusted according to the included angle of different automotive castings, and the first corrugated pipe 75 is then adjusted accordingly. Corrugated pipe 74 is a pipe that can be bent and adjusted to any shape. It has plasticity and toughness, and can be deformed and stretched. It is similar to the pipe connected to a household gas water heater. After adjusting the No. 1 air deflector 75 to a suitable dust blowing position, an external fan is connected to the air inlet pipe 71. The fan blows air into the interior of the fixed base 7 through the air inlet pipe 71. The air passes through the air outlet pipe 72 and reaches the No. 1 diversion box 73, where it is diverted into the No. 1 corrugated pipe 74. Finally, the No. 1 scraper blade 14 pushes the burrs off in front, and the No. 1 air deflector 75 follows closely behind, blowing air to remove the burrs and debris, thus playing a role in burr cleaning.

[0038] A second air plate 8 is slidably connected to the first air plate 75; square grooves are respectively formed between the first air plate 75 and the second air plate 8, the length of the square groove of the second air plate 8 is less than the length of the square groove of the first air plate 75, and the second air plate 8 can be connected to the first air plate 75 through the square groove after sliding from the initial position; when blowing away and cleaning large areas of burrs and debris, the second air plate 8 is slid away from the first air plate 75, at which time the square groove of the second air plate 8, which was originally blocked by the first air plate 75, is connected to the first air plate 75. The grooves are connected, and part of the air force entering the No. 1 air plate 75 is blown out into the No. 2 air plate 8. The No. 1 air plate 75 works in conjunction with the extended No. 2 air plate 8 to simultaneously blow away burrs and debris, improving the effect of burr removal. When the No. 2 air plate 8 is not in use, it can be slid in the opposite direction and placed on the upper surface of the No. 1 air plate 75. The upper surface of the No. 1 air plate 75 is misaligned and blocked by the square groove of the No. 2 air plate 8. The air force entering the No. 1 corrugated pipe 74 is only blown out from the No. 1 air plate 75, which plays a role in controlling the extension of the air blowing width at the No. 1 air plate 75.

[0039] A second diversion box 9 is fixedly connected to the top of the first diversion box 73; a first air duct 92 is opened on the side of the device frame 1 near the first scraper blade 14; a second corrugated pipe 91 connects the second diversion box 9 and the first air duct 92; a second air duct 94 is opened on the side of the first connecting plate 12 near the first scraper blade 14; a third corrugated pipe 93 connects the second diversion box 9 and the second air duct 94; a sealing component is provided inside the first diversion box 73, which is used to control the connection state at the second diversion box 9; when the two first scraper blades 14 on the device frame 1 and the first connecting plate 12 are connected... When scraping automotive castings, some burrs tend to adhere to the No. 1 scraper blade 14. By increasing the power of the blower, a strong airflow is blown into the interior of the No. 1 diversion box 73 and the sealing component is opened. Most of the airflow is blown out from the No. 1 air plate 75, and some airflow is guided to the No. 1 air duct 92, which extends from the No. 2 corrugated pipe 91, and the No. 2 air duct 94, which extends from the No. 3 corrugated pipe 93. The No. 2 corrugated pipe 91 and the No. 3 corrugated pipe 93 are made of the same material as the No. 1 corrugated pipe 74 and have the same plasticity. The No. 1 air duct 92 and the No. 2 air duct 94 blow air onto the outer wall of the two No. 1 scraper blades 14 to remove impurities and reduce the adhesion of burrs and debris on the No. 1 scraper blades 14.

[0040] The sealing assembly includes a fixed rod 95, a sealing plate 96, and an elastic element 97. The fixed rod 95 is fixed to the inner wall of the first diversion box 73. The sealing plate 96 is slidably connected to the outer wall of the fixed rod 95. The elastic element 97 is sleeved on the fixed rod 95. When the fan is working, the fan power is set to three levels. At the first power level, the air blows into the first diversion box 73, the air force is blocked by the sealing plate 96, and the air enters the first corrugated pipe 74 and is discharged through the first air plate 75. At the second power level, the air blows into the first diversion box 73, and the air force pushes the sealing plate 96 to slide on the fixed rod 95. 5. When the elastic element 97 is compressed and contracted to half position, the air enters the first corrugated pipe 74 and is simultaneously discharged from the first wind plate 75 and the extended second wind plate 8. When the power is at the third level, a strong wind enters the first diversion box 73, and the wind pushes the sealing plate 96 to slide on the fixed rod 95. The elastic element 97 is compressed and contracted. At this time, the channel at the second diversion box 9 is opened. Part of the air enters the first corrugated pipe 74 and is discharged. The other part of the air enters the second diversion box 9 and is blown out from the first wind trough 92 and the second wind trough 94, which plays the role of controlling the opening and closing of the air blowing channel according to the power of the fan.

[0041] Working process: During the deburring and cutting of automotive castings, according to the different angles of different automotive castings, turning knob 13 drives roller 11 to rotate. Connecting plate 12 rotates accordingly, engaging with frame 1 to form an angle suitable for the automotive casting. Friction damper 1 limits the angle between frame 1 and connecting plate 12. Friction damper 1 mainly restricts the rotation of roller 11 after angle adjustment. Scraper 14 on frame 1 conforms to the angle of the automotive casting. On one side, another scraper blade 14 on the first connecting plate 12 fits against the other side of the corner of the automotive casting. The device frame 1 and the first connecting plate 12 can be adaptively adjusted to suit deburring and cutting of automotive castings with acute, right, and obtuse angles. The pushing device frame 1 slides on the surface of the automotive casting, and the two scraper blades 14 can push and scrape the corner of the automotive casting to effectively cut burrs at different angles of the automotive casting. When deburring the corner of the automotive casting at different angles, the mounting plate 21 and the moving... After connecting the equipment and adjusting the angle of the scraper on the frame 1 and the first connecting plate 12, the output end of the electric push rod 2 extends, driving the two first scraper blades 14 to push against the included angle of the automotive casting from one end to the other. Then, the output end of the electric push rod 2 retracts, and the triangular grooves on the two first scraper blades 14 perform a secondary scraping on the surface of the automotive casting, improving the deburring effect. When the first scraper blade 14 on the frame 1 scrapes one side of the automotive casting, it utilizes… The operation of the first electric slider 3 drives the sliding plate 31 to slide, and the connecting rod 32 drives the connected second scraper 33 to slide out of the inner wall of the device frame 1 in sync. This allows the first scraper 14 and the second scraper 33 to work together to scrape off burrs from the surface of longer automotive castings. When the triangular groove on the second scraper 33 is reset at the output end of the electric push rod 2, it performs a second scraping on the surface of the automotive casting. This allows the length of burrs removed at the device frame 1 to be adjusted according to the angle of the different lengths of the automotive castings, thus improving the applicability of the deburring and cutting device.

[0042] When the first scraper blade 14 on the first connecting plate 12 scrapes one side of the automotive casting, the second electric slider 4 drives the first fixed plate 41 to slide, and the third scraper blade 42 slides out of the inner wall of the first connecting plate 12 at the same time. This allows the first scraper blade 14 and the third scraper blade 42 on the first connecting plate 12 to work together to push away burrs on the longer surface of the automotive casting. The triangular groove on the third scraper blade 42 is used to scrape the surface of the automotive casting a second time. The length of burr removal at the first connecting plate 12 can be adjusted according to the angle of the different lengths of the automotive casting, further improving the applicability of the deburring and cutting device.

[0043] When deburring and cutting the corner of a gate-shaped automotive casting, the second knob 52 is turned to rotate the second roller 5, causing the second connecting plate 51 to rotate. This causes the connecting plate 51, originally retracted below the device frame 1, to rotate and fit against one side of the automotive casting. Three first scraper blades 14 are respectively attached to the surfaces of the automotive casting requiring deburring. The second friction damper is limited after the second roller 5 is adjusted by rotation. As the deburring and cutting device is pushed forward, the three first scraper blades 14 scrape away the burrs on the corner of the gate-shaped automotive casting. Simultaneously, the second connecting plate 51 can be freely adjusted to fit different corner angles of the automotive casting, effectively deburring the automotive casting on three sides. After deburring and cutting the surface of the automotive casting, a large number of burrs are scraped away by the first scraper blades 14. First, adjust the position of the No. 1 air deflector 75 according to the angle of different automotive castings. The No. 1 corrugated pipe 74 is a pipe that can be bent and adjusted to any shape. It has plasticity and toughness, and can be deformed and stretched, similar to the pipe connected to a household gas water heater. After adjusting the No. 1 air deflector 75 to a suitable dust blowing position, use the air intake pipe 71 connected to an external fan. The fan blows air into the interior of the fixed seat 7 through the air intake pipe 71. The air passes through the air outlet pipe 72 and reaches the No. 1 diverter box 73, where it is diverted into the No. 1 corrugated pipe 74. Finally, the No. 1 scraper blade 14 pushes the burrs off in front, and the No. 1 air deflector 75 follows closely behind, blowing away the burrs and debris, thus cleaning the burrs. When cleaning large areas of burrs and debris, the No. 2 air deflector 8 is slid away from the No. 1 air deflector 75. At this time, the square groove of the second air plate 8, which was originally blocked by the first air plate 75, is connected to the square groove of the first air plate 75. Some of the air force entering the first air plate 75 enters the second air plate 8 and is blown out. The first air plate 75, together with the extended second air plate 8, simultaneously blows away burrs and debris, improving the burr removal effect. When the second air plate 8 is not in use, it can be slid in the opposite direction and placed on the upper surface of the first air plate 75. The upper surface of the first air plate 75 is misaligned and blocked by the square groove of the second air plate 8. The air force entering the first corrugated pipe 74 is only blown out from the first air plate 75, which plays a role in controlling the extension of the air blowing width at the first air plate 75. When the two first scraper blades 14 on the device frame 1 and the first connecting plate 12 push the automotive casting, some burrs are easily attached to the first scraper blades 14. The high-powered fan blows strong air into the interior of the No. 1 distribution box 73 and opens the sealing components. Most of the air is blown out from the No. 1 air plate 75, and some air is guided to the No. 1 air duct 92, which extends from the No. 2 corrugated pipe 91, and the No. 2 air duct 94, which extends from the No. 3 corrugated pipe 93. The No. 2 corrugated pipe 91 and the No. 3 corrugated pipe 93 are made of the same material as the No. 1 corrugated pipe 74 and have the same plasticity. The No. 1 air duct 92 and the No. 2 air duct 94 blow air onto the outer wall of the two No. 1 scraper blades 14 to remove impurities and reduce the adhesion of burrs and debris on the No. 1 scraper blades 14. When the fan is working, the fan power is set to three levels. At the first power level, the air blows into the interior of the No. 1 distribution box 73, and the air force is blocked by the sealing plate 96. The air enters the No. 1 corrugated pipe 74 and is guided to the No. 1 air plate 75 for discharge.At the second power setting, air enters the first distribution box 73, the wind pushes the sealing plate 96 to slide on the fixed rod 95, and the elastic element 97 is squeezed and contracted to half position. The air enters the first corrugated pipe 74 and is simultaneously discharged from the first air plate 75 and the extended second air plate 8. At the third power setting, strong air enters the first distribution box 73, the wind pushes the sealing plate 96 to slide on the fixed rod 95, and the elastic element 97 is squeezed and contracted. At this time, the channel at the second distribution box 9 is opened, some air enters the first corrugated pipe 74 and is discharged, and the other part of the air enters the second distribution box 9 and is blown out from the first air duct 92 and the second air duct 94, which plays the role of controlling the opening and closing of the air blowing channel according to the fan power.

[0044] When the blades of the two No. 1 scrapers 14 on the device frame 1 and the No. 1 connecting plate 12 have been scraping burrs for a long time, some burr debris tends to adhere to the blades of the two No. 1 scrapers 14. During the process of the No. 2 scraper 33 and the No. 3 scraper 42 being slid by the No. 1 electric slider 3 and the No. 2 electric slider 4 respectively, the two whetstones 61 on the No. 2 fixing plate 6 and the No. 1 fixing plate 41 respectively grind the blades of the two No. 1 scrapers 14, improving the burr removal effect of the two No. 1 scrapers 14. At the same time, the two whetstones 61 can also scrape off the debris at the blades of the two No. 1 scrapers 14, reducing the adhesion of burrs on the two No. 1 scrapers 14.
