Description

Technical Field

[0001] The invention relates to the technical field of burr removal, in particular to a device for removing burrs from the surface of an aluminum die casting. Background Art

[0002] Aluminum die castings are parts made of aluminum alloy materials through die casting. Die casting is a process in which molten metal is injected into a high-precision mold and cooled and solidified under high pressure. Die casting can produce aluminum parts with precise dimensions and smooth surfaces. Aluminum alloys have good strength and corrosion resistance, and are light in weight, which helps to reduce the burden on the overall structure.

[0003] During the production process of aluminum die castings, due to the characteristics of high-pressure injection and cooling, some irregular burrs or flash are often formed on the surface of the castings. The burrs may affect the appearance and dimensional accuracy of the aluminum die castings. At the same time, the burrs may affect the assembly, fit and function of the aluminum die castings. Especially in precision mechanical parts, the burrs may interfere with the normal operation of the parts. Common deburring methods include mechanical deburring (such as grinding and polishing), chemical deburring (such as pickling) and ultrasonic deburring.

[0004] At present, the common method of removing burrs from aluminum die-castings is to put the aluminum die-castings into clean water and use a magnetic needle and cleaning liquid to remove the burrs from the aluminum die-castings. However, the cleaning liquid is usually corrosive and irritating, which causes the operator to come into contact with the cleaning liquid during the process of picking up or placing the aluminum die-castings, causing damage to the body.

[0017] 1. The device for removing burrs from the surface of aluminum die-castings rotates a driving gear by cooperating with a rotating motor and a first pulley group, and drives the driven gear to rotate during the rotation of the driving gear. During the rotation of the driven gear, the restrictions of the driving rod, the first sliding block, the second sliding block, the first track groove and the second track groove are used to make the driven gear rotate with the driving gear as the center of the circle, and the first sliding block can slide from one end of the first track groove to the other end, and similarly, the second sliding block slides from one end of the second track groove to the other end, so that the first placement plate can reciprocate up and down, and the operator only needs to put the aluminum die-casting on the surface of the first placement plate and take the aluminum die-casting on the surface of the first placement plate, so as to avoid the operator directly inserting his hand into the cleaning liquid during the process of taking or placing the aluminum die-casting, thereby reducing the direct contact of the operator with the cleaning liquid and improving safety.

[0018] 2. The device for removing burrs from the surface of aluminum die-castings is installed between two second sliding blocks through a second placement plate. Therefore, during the movement of the first sliding block and the second sliding block, the first placement plate and the second placement plate are in a parallel and contacting state during the movement of each other. At the same time, the aluminum die-casting on the surface of the first placement plate is pushed to the surface of the first placement plate by the cooperation of the pushing cylinder, the third track groove and the pushing plate. At the same time, the first placement plate and the second placement plate continue, so that the first placement plate moves to the bottom side of the feed port for the convenience of the operator to load the material, and the second placement plate moves to the side of the discharge port for the convenience of the operator to take the material. During the movement of the second placement plate, the nozzle flushes the aluminum die-casting placed on the surface of the second placement plate, so that the flushing of the aluminum die-casting is completed when the second placement plate reaches the discharge port. Not only can the aluminum die-casting be deburred while the aluminum die-casting is being deburred, but another batch of aluminum die-castings can also be flushed, thereby reducing the operation of the operator, automatically removing burrs from the surface of the aluminum die-casting and flushing the aluminum die-casting, and improving the processing speed of the processing process, which can significantly improve production efficiency and speed up the production cycle.

[0019] 3. The device for removing burrs from the surface of aluminum die-castings, while the second sliding block slides with the second track groove, utilizes the cooperation of the air pipe, the connecting channel and the pressing block to make the pressing block descend. When the second sliding block slides to the end of the second track groove, the second placement plate reaches the upper side of the discharge port. At the same time, the pressing block presses the second placement plate, and the second placement plate swings by utilizing the cooperation of the one-way torsion spring and the second rotating rod, so that the aluminum die-casting placed on the surface of the second placement plate falls, thereby realizing automatic unloading of the flushed aluminum die-castings; not only that, through the cooperation of the limit block and the push groove and the push spring, the push block pushes the aluminum die-casting on the surface of the first placement plate to the surface of the second placement plate, and the limit block plays a blocking role on the aluminum die-casting, thereby minimizing the falling of the aluminum die-casting during the plate changing process.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1: This embodiment is intended to promote the solution of the common method of removing burrs from aluminum die castings, which is to put the aluminum die castings into clean water and use a magnetic needle and cleaning liquid to remove burrs from the aluminum die castings. However, the cleaning liquid is usually corrosive and irritating, which causes the operator to come into contact with the cleaning liquid during the process of picking up or placing the aluminum die castings, causing damage to the body. Please refer to Figure 1-Figure 10 A device for removing burrs from the surface of aluminum die castings includes an equipment body 110, a feeding port 111 for feeding castings is installed on the upper side of the equipment body 110, a discharging port 112 for discharging castings is opened on the side of the equipment body 110, a cleaning tank 113 for removing burrs from the surface of aluminum die castings is installed inside the equipment body 110, a rotating shaft 114 is rotatably installed inside the cleaning tank 113, a rotating motor 115 for driving the rotating shaft 114 is installed on the side of the equipment body 110, a stirring plate 120 for stirring the cleaning liquid is installed inside the equipment body 110, a first placement plate 121 for lifting the casting is movably installed inside the equipment body 110, and a first track groove 122 and a second track groove 123 for guiding the moving direction of the first placement plate 121 are opened inside the equipment body 110.

[0034] There are two first track grooves 122, which are respectively opened on both sides of the device body 110. The second track groove 123 has the same specifications as the first track groove 122. The second track groove 123 is horizontally arranged on the inner wall of the device body 110, and the first track groove 122 is horizontally and vertically arranged inside the device body 110. The first track groove 122 and the second track groove 123 form a cross-intersecting sliding groove. A first sliding block 130 is slidably installed inside the first track groove 122, and a second sliding block 131 is slidably installed inside the second track groove 123. A driving rod 132 is installed between the second sliding block 131 and the first sliding block 130, and the ends of the driving rod 132 are rotatably arranged with the second sliding block 131 and the first sliding block 130 respectively.

[0035] Two first rotating rods 140 are installed on the side of the first placement plate 121. The two first rotating rods 140 are located on both sides of the first placement plate 121. The two first rotating rods 140 are located at a diagonal position relative to the first placement plate 121. The two first rotating rods 140 are perpendicular to the side walls of the first placement plate 121. The first rotating rods 140 are connected to the first sliding blocks 130 on both sides. A driving gear 151 is installed on the side of the driving rod 132. A driving gear 150 is rotatably installed on the inner wall of the equipment body 110. The driving gear 151 is meshed with the driving gear 150. When the driving gear 150 rotates, the driving gear 151 rotates with the driving gear 150 as the center of the circle. A connecting shaft 152 is installed on the side of the driving gear 150. A first pulley group 153 for transmission is installed between the connecting shaft 152 and the rotating shaft 114. The first pulley group 153 is a common transmission device, usually including a transmission belt and a pulley. Its specific model, working principle and usage are well known to those skilled in the art, and will not be elaborated here.

[0036] See Figure 1 , Figure 2 , Figure 4 and Figure 5 In a specific implementation, the rotating shaft 114 is driven to rotate by the rotating motor 115, and the rotating shaft 114 uses the transmission of the first pulley set 153 to rotate the driving gear 150. During the rotation of the driving gear 150, the driving gear 151 is driven to rotate. Since the driving gear 151 is installed on the side of the driving rod 132, the driving gear 151 is restricted by the driving rod 132. At the same time, the first sliding block 130 and the second sliding block 131 installed at both ends of the driving rod 132 are restricted by the first track groove 122 and the second track groove 123, so that the driving gear 151 rotates with the driving gear 150 as the center of the circle, and the first sliding block 130 can slide from one end of the first track groove 122 to the other end, and similarly, the second sliding block 131 slides from one end of the second track groove 123 to the other end;

[0037] See Figure 1 , Figure 2 , Figure 4 and Figure 5 , the first placing plate 121 uses the cooperation of the first rotating rod 140 and the first sliding block 130 so that the first placing plate 121 can move along the track of the first sliding block 130. When the first placing plate 121 moves to the end of the first track groove 122 following the first sliding block 130, the operator manually puts the aluminum die casting through the feed port 111 on the surface of the first placing plate 121. In the process of the first placing plate 121 moving to the other end of the first track groove 122 following the first sliding block 130, the first placing plate 121 is The placement plate 121 reaches the bottom of the cleaning tank 113, and the cleaning liquid overflows the aluminum die-casting placed on the surface of the first placement plate 121, so that the cleaning liquid soaks the aluminum die-casting. At the same time, the cleaning liquid inside the cleaning tank 113 is stirred by the stirring plate 120 to make the cleaning liquid and the aluminum die-casting fully contact as much as possible. After a period of time, when the burrs on the surface of the aluminum die-casting are removed, the first placement plate 121 moves following the first sliding block 130 so that the aluminum die-casting reaches the feed port 111 again, which is convenient for the operator to pick up the aluminum die-casting.

[0038] In this embodiment: the driving gear 150 is rotated by the cooperation of the rotating motor 115 and the first pulley group 153, and the driving gear 151 is driven to rotate during the rotation of the driving gear 150. During the rotation of the driving gear 151, the driving rod 132, the first sliding block 130, the second sliding block 131, the first track groove 122 and the second track groove 123 are used to limit the driving gear 151 to rotate with the driving gear 150 as the center, and the first sliding block 130 can slide from one end of the first track groove 122 to the other end, and the second sliding block 131 slides from one end of the second track groove 123 to the other end, so that the first placement plate 121 can reciprocate up and down, and the operator only needs to place the aluminum die-casting on the surface of the first placement plate 121 and take the aluminum die-casting on the surface of the first placement plate 121, and try to avoid the operator directly inserting his hand into the cleaning liquid during the process of taking or placing the aluminum die-casting, thereby reducing the operator's direct contact with the cleaning liquid and improving safety.

[0039] Embodiment 2: This embodiment is intended to solve the problem that cleaning liquid will remain on the surface of aluminum die castings after burrs are removed, and the surface of aluminum die castings needs to be rinsed with clean water. However, at present, after the burrs are removed from aluminum die castings, they need to be manually salvaged and rinsed separately, which is a relatively troublesome operation. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 - Fig.10A third track groove 170 is opened inside the equipment body 110, and a pushing cylinder 171 is installed inside the equipment body 110. A pushing block 172 is movably installed at the movable end of the pushing cylinder 171. A sliding groove 173 is opened on the side of the pushing block 172. A slider 174 is slidably installed inside the sliding groove 173. The slider 174 is hinged to the movable end of the pushing cylinder 171. A sliding column 175 is installed on the side of the pushing block 172. The sliding column 175 slides with the third track groove 170. When the pushing block 172 moves along the track of the third track groove 170, the bottom side of the pushing block 172 contacts the first placement plate 121.

[0040] See Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 A movable second placement plate 141 is installed inside the device body 110, and two second rotating rods 142 are installed on the side of the second placement plate 141. The two second rotating rods 142 are located on both sides of the second placement plate 141. The two second rotating rods 142 are located at the diagonal position relative to the second placement plate 141. The two second rotating rods 142 are perpendicular to the side wall of the second placement plate 141. Two second rotating rods 142 are installed on the side of the second placement plate 141. The two second rotating rods 142 are located on both sides of the second placement plate 141. The two second rotating rods 142 are located at a diagonal position relative to the second placement plate 141, and the two second rotating rods 142 are perpendicular to the side walls of the second placement plate 141. At the same time, the two second rotating rods 142 are connected to the two second sliding blocks 131, so that the second placement plate 141 can reciprocate following the moving direction of the second sliding block 131. A nozzle 161 is installed inside the equipment body 110, and a collecting box 162 is installed on the bottom side of the nozzle 161. The first placement plate 121 and the second placement plate 141 are both configured as filter plates.

[0041] See Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6In a specific implementation, the first placement plate 121 and the second placement plate 141 cooperate with the first sliding block 130, the second sliding block 131, the first track groove 122 and the second track groove 123 to make the first placement plate 121 and the second placement plate 141 parallel and in contact with each other during the movement. At this time, the rotating motor 115 stops moving, and at the same time, the cylinder 171 pushes the push block 172 to move along the third track groove 170, so that the bottom side of the push block 172 drops and contacts the surface of the first placement plate 121, so that the push block 172 pushes the aluminum die casting on the surface of the first placement plate 121 to the surface of the second placement plate 141 during the movement. At the same time, The rotating motor 115 continues to start, and the first sliding block 130 and the second sliding block 131 continue to move, so that the first placement plate 121 moves to the bottom side of the feed port 111 to facilitate the operator to load the material, and the second placement plate 141 moves to the side of the discharge port 112 to facilitate the operator to take the material; during the movement of the second placement plate 141, the nozzle 161 flushes the aluminum die-castings placed on the surface of the second placement plate 141, so that the flushing of the aluminum die-castings is completed in the process of the second placement plate 141 reaching the discharge port 112, thereby reducing the operator's operation, automatically removing burrs on the surface of the aluminum die-castings and flushing the aluminum die-castings, and improving the processing speed of the processing, which can significantly improve production efficiency and accelerate the production cycle.

[0042] In this embodiment: the second placement plate 141 is installed between the two second sliding blocks 131, so that during the movement of the first sliding block 130 and the second sliding block 131, the first placement plate 121 and the second placement plate 141 are parallel and in contact with each other during the movement. At the same time, the aluminum die-casting on the surface of the first placement plate 121 is pushed to the surface of the first placement plate 121 by the cooperation of the pushing cylinder 171, the third track groove 170 and the pushing plate. At the same time, the first placement plate 121 and the second placement plate 141 continue to move, so that the first placement plate 121 moves to the bottom side of the feed port 111 for easy operation. The author loads the material, and the second placement plate 141 moves to the side of the discharge port 112 for the convenience of the operator to take it; during the movement of the second placement plate 141, the nozzle 161 rinses the aluminum die-castings placed on the surface of the second placement plate 141, so that the flushing of the aluminum die-castings is completed in the process of the second placement plate 141 reaching the discharge port 112, not only can the aluminum die-castings be deburred, but also another batch of aluminum die-castings can be flushed, which reduces the operator's operation, automates the deburring of the surface of the aluminum die-castings and the flushing of the aluminum die-castings, and improves the speed of the processing process, which can significantly improve production efficiency and accelerate the production cycle.

[0043] Embodiment 3: This embodiment is intended to help solve the problem that the aluminum die-casting may fall off when the push block 172 pushes the aluminum die-casting on the surface of the first placement plate 121 to the second first placement plate 121. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1 - Fig.10 A one-way torsion spring 160 is installed between the second placement plate 141 and the second rotating rod 142, a sliding wheel 180 is installed on the side of the second sliding block 131, a transverse groove 181 is installed inside the second track groove 123, an air pipe 182 is installed inside the transverse groove 181, and the bottom side of the sliding wheel 180 is in sliding contact with the air pipe 182. A crossbeam 190 is installed inside the device body 110, a connecting channel 191 is opened inside the crossbeam 190, a pressing block 192 is movably installed inside the connecting channel 191, and a connecting pipe 193 is installed between the connecting channel 191 and the air pipe 182. When the sliding wheel 180 slides toward one end of the air pipe 182, the pressing block 192 descends from the connecting channel 191, and the pressing block 192 presses the second placement plate 141, and a reset spring 195 for resetting the pressing block 192 is installed inside the connecting channel 191.

[0044] See Figure 5 , Figure 6 , Fig. 9 , Fig.10 and Fig.11 In a specific implementation, during the process of the second sliding block 131 moving toward the discharge port 112, the sliding wheel 180 installed on the bottom side of the second sliding block 131 squeezes the gas inside the air pipe 182, so that the gas inside the air pipe 182 reaches the connecting channel 191 through the connecting pipe 193, and the gas reaching the connecting channel 191 squeezes the pressing block 192, so that the pressing block 192 descends. When the second sliding block 131 slides to the end of the second track groove 123, the second placing plate 141 reaches the upper side of the discharge port 112. At the same time, the pressing block 192 presses the second placing plate 141. The second placing plate 141 swings by the cooperation of the one-way torsion spring 160 and the second rotating rod 142, so as to be placed on the second placing plate 141. The aluminum die-castings on the surface of the plate 141 fall off, and the aluminum die-castings after washing are automatically unloaded. A rotating column 220 is installed on the side of the driving gear 150, and a docking column 230 is installed on the side of the stirring plate 120. A second pulley group 240 is installed between the rotating column 220 and the docking column 230. When the driving gear 150 rotates, the stirring plate 120 can be rotated through the cooperation of the second pulley group 240 to keep the cleaning liquid in a stirring state as much as possible. A flipping plate 250 for stirring the cleaning liquid is installed inside the equipment body 110, and a driving motor is connected to the side of the flipping plate 250, so that the driving motor can drive the flipping plate 250. It is a common technology that the driving motor drives the flipping plate 250 to rotate, so this embodiment will not be described in detail.

[0045] See Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 and Fig.11 In a specific implementation, a limit block 210 is movably installed on the upper side of the second placement plate 141, a pushing groove 211 is opened on the surface of the second placement plate 141, the limit block 210 is movably installed inside the pushing groove 211, and a pushing spring 212 is installed between the limit block 210 and the pushing groove 211, so that when the pushing block 172 pushes the aluminum die-casting on the surface of the first placement plate 121 to the surface of the second placement plate 141, the limit block 210 plays a blocking role on the aluminum die-casting.

[0046] In this embodiment: while the second sliding block 131 slides with the second track groove 123, the cooperation of the air pipe 182, the connecting channel 191 and the pressing block 192 is used to make the pressing block 192 descend. When the second sliding block 131 slides to the end of the second track groove 123, the second placement plate 141 reaches the upper side of the discharge port 112. At the same time, the pressing block 192 presses the second placement plate 141, and the second placement plate 141 swings by the cooperation of the one-way torsion spring 160 and the second rotating rod 142, so that the aluminum die-casting placed on the surface of the second placement plate 141 falls, and the aluminum die-casting after washing is automatically unloaded; not only that, through the cooperation of the limit block 210 and the push groove 211 and the push spring 212, when the push block 172 pushes the aluminum die-casting on the surface of the first placement plate 121 to the surface of the second placement plate 141, the limit block 210 plays a blocking role on the aluminum die-casting, thereby minimizing the aluminum die-casting from falling during the plate changing process.
