The deburring and cutting process during the production of automotive castings is crucial in automotive manufacturing, mainly used to remove burrs and flash and other excess materials on the surface of the castings to ensure the accuracy and quality of the castings.

[0003] A patent application with the publication number CN116748602A discloses a deburring device for automotive lock core castings, including a frame, a fixture mechanism, a proximity drive mechanism, a keyhole push knife, and a through-hole push knife. The fixture mechanism is arranged on the frame, and the keyhole of the lock core is arranged downward in the fixture mechanism. The proximity drive structure has a first mounting component and a second mounting component that can successively approach the lock core.

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0023] As Figures 1 to 3 , Figure 6 shown, a deburring and cutting device for automobile castings according to an embodiment of the present invention includes a device frame 1; one outer wall of the device frame 1 is rotatably connected with a first rotating roller 11, and a first friction damper is arranged between the device frame 1 and the first rotating roller 11; one end of the first rotating roller 11 away from the device frame 1 is fixedly connected with a first connecting plate 12; one end of the first rotating roller 11 away from the first connecting plate 12 is fixedly connected with a first knob 13; first scraping knives 14 are fixedly connected to the outer walls of the device frame 1 and the first connecting plate 12; when deburring and cutting automobile castings, according to the included angles of different automobile castings at different angles, turn the first knob 13 to drive the first rotating roller 11 to rotate, and the first connecting plate 12 rotates accordingly to cooperate with the device frame 1 to form an included angle adapted to the automobile casting. The included angle formed by the device frame 1 and the first connecting plate 12 is limited by the first friction damper. The first friction damper is mainly used to limit the rotation of the first rotating roller 11 after adjusting the angle. The first scraping knife 14 on the device frame 1 fits one side of the included angle of the automobile casting, and the other first scraping knife 14 on the first connecting plate 12 fits 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. Push the device frame 1 to slide on the surface of the automobile casting, and the two first scraping knives 14 can push and shovel the burrs at the included angle of the automobile casting. Finally, use a special tool to polish and deburr the deepest part of the included angle, which can effectively cut the burrs at different angle included angles of the automobile casting.

[0024] A triangular inclined groove is formed in the first scraping cutter 14. On the outer wall of the device frame 1 and on the side far from the first scraping cutter 14, an electric push rod 2 is fixedly connected, and the output end of the electric push rod 2 is fixedly connected to the outer wall of the device frame 1. One end of the electric push rod 2 far from the device frame 1 is fixedly connected with a mounting plate 21. When deburring the included angles of different angles of the automobile casting, the mounting plate 21 is connected with the mobile device. After adjusting the angles 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 scraping cutters 14 to fit the included angle of the automobile casting and push and scrape first, from one end of the automobile casting to the other end. Subsequently, the output end of the electric push rod 2 retracts, and the triangular inclined grooves on the two first scraping cutters 14 scrape the surface of the automobile casting for the second time, improving the deburring treatment effect on the surface of the automobile casting.

[0025] As Figures 1 to 4 , Figure 6 shown, a first electric slider 3 is slidably connected to the inner wall of the device frame 1. The outer wall of the first electric slider 3 is fixedly connected with a sliding plate 31, 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. One end of the connecting rod 32 far from the sliding plate 31 is fixedly connected with a second scraping cutter 33, and a triangular inclined groove is formed in the second scraping cutter 33. When the first scraping cutter 14 on the device frame 1 scrapes one side surface of the automobile casting, the first electric slider 3 works to drive the sliding plate 31 to slide, and the connecting rod 32 drives the connected second scraping cutter 33 to slide out of the inner wall of the device frame 1 synchronously, so that the first scraping cutter 14 and the second scraping cutter 33 cooperate to push and scrape the burrs on the surface of the longer automobile casting. Cooperating with the triangular inclined groove on the second scraping cutter 33 to scrape the surface of the automobile casting for the second time when the output end of the electric push rod 2 resets, the length of removing burrs at the device frame 1 can be adaptively adjusted according to the included angles of different lengths of the automobile casting, improving the applicability of the deburring cutting device.

[0026] As 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 fixedly connected to the outer wall of the second electric slider 4; a third scraping knife 42 is fixedly connected to one side of the first fixing plate 41, and a triangular inclined groove is formed in the third scraping knife 42; when the first scraping knife 14 on the first connecting plate 12 scrapes one side surface of the automotive casting, the second electric slider 4 is used to drive the first fixing plate 41 to slide, and the third scraping knife 42 synchronously slides out of the inner wall of the first connecting plate 12, so that the first scraping knife 14 on the first connecting plate 12 and the third scraping knife 42 cooperate to push and scrape the burrs on the surface of the longer automotive casting, and the triangular inclined groove on the third scraping knife 42 is used to scrape the surface of the automotive casting for the second time, so that the length of the burrs scraped at the first connecting plate 12 can be adaptively adjusted according to the included angle of different lengths of the automotive casting, further improving the applicability of the deburring and cutting device.

[0027] As Figures 1 to 4 , Figure 6 shown, a second roller 5 is rotatably connected to the sliding plate 31, and a second friction damper is arranged between the second roller 5 and the sliding plate 31; a second connecting plate 51 is fixedly connected to the end of the second roller 5 away from the sliding plate 31, and a first scraping knife 14 is fixedly connected to the second connecting plate 51; a second knob 52 is fixedly connected to the end of the second roller 5 away from the second connecting plate 51; when deburring and cutting the included angle of the portal-shaped automotive casting, the second knob 52 is used to twist the second roller 5 and drive the second connecting plate 51 to rotate, so that the second connecting plate 51 originally retracted under the device frame 1 rotates and fits against one side surface of the automotive casting, and the three first scraping knives 14 respectively fit against the surface of the automotive casting where burrs need to be removed. The second friction damper limits the second roller 5 after its rotation adjustment. As the deburring and cutting device is pushed forward, the three first scraping knives 14 push and scrape the burrs on the included angle of the portal-shaped automotive casting. At the same time, according to the included angle of different automotive castings, the second connecting plate 51 can be adjusted and adapted at will, playing a role in deburring the three-sided automotive casting.

[0028] As Figures 1 to 6As shown, a second fixing plate 6 is fixedly connected to one end of the second scraping blade 33 away from the connecting rod 32; grinding stones 61 are fixedly connected to both the second fixing plate 6 and the first fixing plate 41, and the grinding stones 61 are attached to the outer wall of the first scraping blade 14; when burrs are pushed and shoveled at the cutting edges of the two first scraping blades 14 on the device frame 1 and the first connecting plate 12 for a long time, some burr waste chips are likely to adhere to the cutting edges of the two first scraping blades 14. During the process of driving the second scraping blade 33 and the third scraping blade 42 to slide by the first electric slider 3 and the second electric slider 4 respectively, the two grinding stones 61 on the second fixing plate 6 and the first fixing plate 41 polish the cutting edges of the two first scraping blades 14 respectively, improving the burr removal effect of the two first scraping blades 14. At the same time, the two grinding stones 61 can also scrape off the waste chips at the cutting edges of the two first scraping blades 14, reducing the adhesion of burrs on the two first scraping blades 14.

[0029] As Figures 1 to 4 , Figure 6 , Figure 7 , Figure 8 As shown, a fixing seat 7 is fixedly connected to one side of the second connecting plate 51 close to the electric push rod 2; an air inlet pipe 71 and an air outlet pipe 72 are respectively fixedly connected to the fixing seat 7; one end of the air outlet pipe 72 away from the fixing seat 7 is fixedly connected to a first flow dividing box 73; a first corrugated pipe 74 is fixedly connected to the bottom end of the first flow dividing box 73; a first air plate 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 scraping blade 14. First, adjust the position of the first air plate 75 according to the angles of different automotive castings. The first corrugated pipe 74 is a pipe that can be bent and adjusted in shape at will, with plastic toughness, capable of deforming and stretching, similar to the pipe connected to a household gas water heater. After adjusting the first air plate 75 to the appropriate dust blowing position, an external fan is connected through the air inlet pipe 71. When the fan works, air is blown into the interior of the fixing seat 7 through the air inlet pipe 71. The air reaches the first flow dividing box 73 through the air outlet pipe 72 and then flows into the first corrugated pipe 74. Finally, the first scraping blade 14 shovels the burrs to fall in the front, and the first air plate 75 blows immediately behind to remove the burr waste chips, playing a role in cleaning the burrs.

[0030] 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 that 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 and cleaning large-area burr waste chips, the second air plate 8 is slid away from the first air plate 75. At this time, the square groove of the second air plate 8 originally blocked by the first air plate 75 is connected to the square groove of the first air plate 75, and part of the wind entering the first air plate 75 blows out into the second air plate 8. The first air plate 75 cooperates with the extended second air plate 8 to blow the burr waste chips synchronously, improving the effect of burr blowing. When the second air plate 8 is not in use, it can be reversely slid onto the upper surface of the first air plate 75. The upper surface of the first air plate 75 misaligns and blocks the square groove of the second air plate 8, and the wind entering the first bellows 74 only blows out from the first air plate 75, playing a role in controlling the extension of the blowing width at the first air plate 75.

[0031] A second flow dividing box 9 is fixedly connected to the top end of the first flow dividing box 73; a first air groove 92 is formed on one side of the device frame 1 close to the first scraping knife 14; a second bellows 91 is connected between the second flow dividing box 9 and the first air groove 92; a second air groove 94 is formed on one side of the first connecting plate 12 close to the first scraping knife 14; a third bellows 93 is connected between the second flow dividing box 9 and the second air groove 94; a blocking component is arranged inside the first flow dividing box 73, and the blocking component is used to control the communication state at the second flow dividing box 9; when the two first scraping knives 14 on the device frame 1 and the first connecting plate 12 push and shovel the automotive casting, some burrs are easily attached to the first scraping knives 14. Increase the power of the fan, blow strong wind into the inside of the first flow dividing box 73 and open the blocking component. Most of the wind blows out from the first air plate 75, and part of the wind is diverted to the first air groove 92 extended by the second bellows 91 and the second air groove 94 extended by the third bellows 93 to blow out. The second bellows 91 and the third bellows 93 are made of the same material as the first bellows 74 and also have plasticity. The first air groove 92 and the second air groove 94 blow and remove impurities on the outer walls of the two first scraping knives 14, reducing the attachment of burr waste chips on the first scraping knives 14.

[0032] The plugging assembly includes a fixing rod 95, a plugging plate 96 and an elastic member 97; the fixing rod 95 is fixedly connected to the inner wall of the first flow dividing box 73; the plugging plate 96 is slidably connected to the outer wall of the fixing rod 95; the elastic member 97 is sleeved on the fixing rod 95; when the fan works, the power of the fan is set to three gears. At the first gear power, the blowing air enters the inside of the first flow dividing box 73, and the wind force is blocked by the plugging plate 96, and the wind enters the first corrugated pipe 74 and is discharged at the first air plate 75; at the second gear power, the blowing air enters the inside of the first flow dividing box 73, and the wind force pushes the plugging plate 96 to slide on the fixing rod 95, and the elastic member 97 is squeezed and contracted to half of its position, and the wind enters the first corrugated pipe 74 and is discharged synchronously at the first air plate 75 and the extended second air plate 8; at the third gear power, strong blowing air enters the inside of the first flow dividing box 73, and the wind force pushes the plugging plate 96 to slide on the fixing rod 95, and the elastic member 97 is squeezed and contracted. At this time, the channel at the second flow dividing box 9 is opened, part of the wind enters the first corrugated pipe 74 and is discharged, and the other part of the wind enters the second flow dividing box 9 and is blown out at the first air groove 92 and the second air groove 94, playing a role in controlling the opening and closing of the blowing channel according to the fan power.

[0033] Working process: When deburring and cutting automotive castings, according to the included angles of different automotive castings at different angles, turn the first knob 13 to drive the first roller 11 to rotate. The first connecting plate 12 rotates accordingly and forms an included angle adapted to the automotive casting with the device frame 1. The included angle formed by the device frame 1 and the first connecting plate 12 is limited by the first friction damper. The first friction damper is mainly used to limit the rotation of the first roller 11 after adjusting the angle. The first scraping knife 14 on the device frame 1 fits one side of the included angle of the automotive casting, and another first scraping knife 14 on the first connecting plate 12 fits the other side of the included angle of the automotive casting. The device frame 1 and the first connecting plate 12 can be adaptively adjusted to be suitable for deburring and cutting automotive castings with acute angles, right angles, and obtuse angles. Push the device frame 1 to slide on the surface of the automotive casting. The two first scraping knives 14 can push and scrape the burrs at the included angle of the automotive casting, and can effectively cut the burrs at different angle included angles of the automotive casting; When deburring the included angles of different angles of the automotive casting, connect the mounting plate 21 to the mobile device. After adjusting the angles of the device frame 1 and the first connecting plate 12 for scraping burrs, the output end of the electric push rod 2 extends, and drives the two first scraping knives 14 to fit the included angle of the automotive casting and push and scrape first, from one end of the automotive casting to the other end. Subsequently, the output end of the electric push rod 2 retracts, and the triangular inclined grooves on the two first scraping knives 14 scrape the surface of the automotive casting for the second time, improving the deburring effect on the surface of the automotive casting; When the first scraping knife 14 on the device frame 1 scrapes one side surface of the automotive casting, utilize the first electric slider 3 to work to drive the sliding plate 31 to slide, and the connecting rod 32 drives the connected second scraping knife 33 to slide out of the inner wall of the device frame 1 synchronously, so that the first scraping knife 14 and the second scraping knife 33 cooperate to push and scrape the burrs on the surface of a longer automotive casting. Cooperate with the triangular inclined grooves on the second scraping knife 33 to scrape the surface of the automotive casting for the second time when the output end of the electric push rod 2 resets, and can adaptively adjust the length of the burrs removed at the device frame 1 according to the included angles of different lengths of the automotive casting, improving the applicability of the deburring and cutting device; When the first scraping knife 14 on the first connecting plate 12 scrapes one side surface of the automotive casting, utilize the second electric slider 4 to work to drive the first fixing plate 41 to slide, and the third scraping knife 42 slides out of the inner wall of the first connecting plate 12 synchronously, so that the first scraping knife 14 on the first connecting plate 12 and the third scraping knife 42 cooperate to push and scrape the burrs on the surface of a longer automotive casting. Cooperate with the triangular inclined grooves on the third scraping knife 42 to scrape the surface of the automotive casting for the second time, and can adaptively adjust the length of the burrs removed at the first connecting plate 12 according to the included angles of different lengths of the automotive casting, further improving the applicability of the deburring and cutting device; When deburring and cutting the angle of the portal-shaped automotive casting, turn the second roller 5 by turning the second knob 52 to drive the second connecting plate 51 to rotate, so that the second connecting plate 51 that was originally retracted under the device frame 1 rotates and fits against one side surface of the automotive casting. The three first scraping blades 14 are respectively fitted against the surface of the automotive casting that needs deburring. The second friction damper limits the second roller 5 after its rotation adjustment. As the deburring and cutting device is pushed forward, the three first scraping blades 14 push and shovel the burrs on the angle of the portal-shaped automotive casting. At the same time, according to the angle of different automotive castings, the second connecting plate 51 can be adjusted and adapted at will, playing a role in deburring the three-sided automotive casting; after deburring and cutting the surface of the automotive casting, a large amount of burrs are scraped off by the first scraping blades 14. First, adjust the position of the first air plate 75 according to the angle of different automotive castings. The first corrugated pipe 74 is a pipe that can be bent and adjusted in shape at will, with plastic toughness, capable of deforming and stretching, similar to the pipe connected to a household gas water heater. After adjusting the first air plate 75 to the appropriate dust blowing position, connect an external fan through the air inlet pipe 71. The fan works and blows air into the inside of the fixed seat 7 through the air inlet pipe 71. The air passes through the air outlet pipe 72 and reaches the first flow dividing box 73, where it is diverted and enters the first corrugated pipe 74. Finally, the first scraping blades 14 push and shovel the burrs to fall in the front, and the first air plate 75 blows closely behind to remove the burr waste, playing a role in cleaning the burrs; when blowing and cleaning a large area of burr waste, slide the second air plate 8 away from the first air plate 75. At this time, the square groove of the second air plate 8 that was originally blocked by the first air plate 75 is connected to the square groove of the first air plate 75. Part of the wind entering the first air plate 75 enters the second air plate 8 and blows out. The first air plate 75 cooperates with the extended second air plate 8 to blow out the burr waste synchronously, improving the effect of blowing out the burrs. When the second air plate 8 is not in use, slide it reversely and place it on the upper surface of the first air plate 75. The upper surface of the first air plate 75 misaligns and blocks the square groove of the second air plate 8, and the wind entering the first corrugated pipe 74 only blows out from the first air plate 75, playing a role in controlling and extending the blowing width at the first air plate 75; when the two first scraping blades 14 on the device frame 1 and the first connecting plate 12 push and shovel the automotive casting, some burrs are easily attached to the first scraping blades 14. Increase the power of the fan, blow strong wind into the inside of the first flow dividing box 73 and open the blocking component. Most of the wind blows out from the first air plate 75, and part of the wind is diverted to the first air groove 92 extended by the second corrugated pipe 91 and the second air groove 94 extended by the third corrugated pipe 93 and blows out. The second corrugated pipe 91 and the third corrugated pipe 93 are made of the same material as the first corrugated pipe 74 and also have plasticity. The first air groove 92 and the second air groove 94 blow air to remove impurities on the outer walls of the two first scraping blades 14, reducing the attachment of burr waste on the first scraping blades 14; when the fan works, the power of the fan is set to three gears. At the first gear power, the wind blows into the inside of the first flow dividing box 73, and the wind is blocked by the blocking plate 96. The wind enters the first corrugated pipe 74 and is introduced to the first air plate 75 and discharged;When in the second gear power, the blowing wind enters the interior of the first flow dividing box 73. The wind force pushes the blocking plate 96 to slide on the fixed rod 95, and the elastic member 97 is squeezed and contracted to half of its position. The wind enters the first corrugated pipe 74 and is discharged synchronously at the first wind plate 75 and the extended second wind plate 8. When in the third gear power, the strong blowing wind enters the interior of the first flow dividing box 73. The wind force pushes the blocking plate 96 to slide on the fixed rod 95, and the elastic member 97 is squeezed and contracted. At this time, the channel at the second flow dividing box 9 is opened. Part of the wind enters the first corrugated pipe 74 and is discharged, and the other part of the wind enters the second flow dividing box 9 and is blown out from the first wind groove 92 and the second wind groove 94, playing a role in controlling the opening and closing of the blowing channel according to the power of the blower. When the cutting edges of the two first scraping blades 14 on the device frame 1 and the first connecting plate 12 are used to push and shovel burrs for a long time, some burr waste chips are likely to adhere to the cutting edges of the two first scraping blades 14. During the process of driving the second scraping blade 33 and the third scraping blade 42 to slide by the first electric slider 3 and the second electric slider 4 respectively, the two grindstones 61 on the second fixing plate 6 and the first fixing plate 41 respectively grind the cutting edges of the two first scraping blades 14, improving the burr removal effect of the two first scraping blades 14. At the same time, the two grindstones 61 can also scrape off the waste chips at the cutting edges of the two first scraping blades 14, reducing the adhesion of burrs on the two first scraping blades 14.
