Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and in particular to a device for removing slag from a cylinder block of an automobile engine. Background Art

[0002] In the related art, the removal of slag from automobile engine cylinder blocks is generally done by fixing the slag with a collision block, and then using a manipulator to clamp the workpiece to knock out the slag. This has the following technical drawbacks:

[0003] (1) When the robot grips the workpiece to hit the slag bag, it is easy to cause the clamping position to change, thereby changing the clamping state and causing the impact position deviation, which can easily lead to the occurrence of shutdown and other phenomena.

[0004] (2) When the manipulator clamps the workpiece to hit the slag bag, the clamping reliability is poor, and the collision position deviation is prone to occur, which increases the scrap rate. The collision time of the slag bag is about 1 minute. During this minute, the hot mold of the casting can only wait, the production cycle is long, and the production efficiency is low. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0006] To this end, an object of the present invention is to provide an automobile engine cylinder block slag removal device that can stably remove slag, shorten the production cycle, improve work efficiency, and improve product quality.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the present invention provides a slag bag removal device for an automobile engine cylinder block, comprising: a base and a bottom plate arranged in a cooperative manner, the middle area of the base and the bottom plate being hollowed out; a workpiece placement plate, arranged in the middle hollow area of the bottom plate; a first oil cylinder, fixedly installed below the bottom plate through a mounting bracket, the first oil cylinder being connected to the workpiece placement plate; a second oil cylinder, installed below the workpiece placement plate, the pull rod of the second oil cylinder passing through the workpiece placement plate and connected to the locking and positioning assembly; a locking and positioning assembly, installed on the workpiece placement plate; a plurality of first slag bag removal parts, respectively installed on the bottom plate and located around the workpiece placement plate, to remove slag bags around the cylinder hole of the engine cylinder block workpiece.

[0008] In this solution, a workpiece placement plate is provided in the hollowed-out area in the middle of the base plate to accommodate the engine cylinder workpiece. This allows the robot to place the engine cylinder workpiece that needs to have its slag removed before performing other operations, significantly reducing mold waiting time. A first oil cylinder is installed and fixed below the base plate to drive the workpiece placement plate up and down, colliding with the multiple first slag removal components installed on the base plate, thereby removing the slag around the cylinder bore of the engine cylinder workpiece. A second oil cylinder installed below the workpiece placement plate cooperates with the locking and positioning assembly to lock the workpiece, ensuring strong placement stability and precise positioning, making it less likely to deviate from its position due to impact.

[0009] The first slag bag removal member includes a slag bag removal plate with an outer surface inclined downward to form a blade, and a slag bag removal push rod with a blade-shaped top. The positions of the slag bag removal plate and the slag bag removal push rod match the slag bags around the cylinder hole of the engine cylinder workpiece.

[0010] Specifically, the robot places the engine cylinder workpiece on the workpiece placement plate, and the cylinder hole of the engine cylinder workpiece corresponds to the locking and positioning assembly; the second oil cylinder is tightened, and the locking and positioning assembly locks and positions the engine cylinder workpiece; the first oil cylinder pushes out, driving the workpiece placement plate downward, thereby driving the engine cylinder workpiece to collide with the first slag bag removal part, removing the slag bag around the cylinder hole of the engine cylinder workpiece, and reset after removal is completed.

[0011] Preferably, the locking and positioning assembly includes: a positioning plate, which is installed on the workpiece placement plate, and the position of the positioning plate matches the cylinder hole position of the automobile engine cylinder workpiece; a rising pin, which is arranged on the positioning plate; a pressure cover, which is sleeved on the rising pin and fixedly connected to the positioning plate; a pull block, which is arranged on the top of the rising pin, and the outer side of the pull block is slidably connected to the inner side of the rising pin, and the pull block is connected to the pull rod of the second oil cylinder.

[0012] In this solution, a locking and positioning assembly is composed of a positioning plate, a pin, a pressure cover, a pull block, etc. The positioning plate is installed on the workpiece placement plate and matches the cylinder hole position of the automobile engine cylinder workpiece to perform preliminary positioning of the automobile engine cylinder workpiece. By setting a pin on the positioning plate and a pull block on the top of the pin, the outer side of the pull block is slidably connected to the inner side of the pin, and the pull block is connected to the pull rod of the second oil cylinder. In this way, the pull rod of the second oil cylinder is tightened to drive the pull block downward, so that the diameter of the pin gradually increases. When encountering a workpiece, the workpiece will be locked and fixed under the action of tension. The fixation is strong and not easy to be dislocated under the action of impact, thereby ensuring the accuracy of slag bag removal. A pressure cover is set on the pin and fixed on the positioning plate, which can limit the moving direction of the pin and further ensure the accuracy of tightening and positioning.

[0013] Preferably, the pulling block includes an inverted quadrangular pyramid body with a wide top and narrow bottom and a connecting hole in the middle, and a T-shaped boss arranged on the side of the inverted quadrangular pyramid body. The cross-sectional area of the T-shaped boss decreases from top to bottom, and the inverted quadrangular pyramid body is fixedly connected to the pull rod of the second oil cylinder; the rising pin is surrounded by four fan-shaped bodies, and is cylindrical with an inverted quadrangular pyramid-shaped through groove in the middle. There is a gap between two adjacent fan-shaped bodies, and each fan-shaped body has a T-shaped keyway. The cross-sectional area of the T-shaped keyway decreases from top to bottom. When the machine is in the stopped state, the lower part of the T-shaped boss is stuck in the T-shaped groove.

[0014] In this solution, by designing the pull block to be wide at the top and narrow at the bottom, the diameter of the expansion pin can gradually increase during the downward movement of the pull block, and the workpiece can be fixed by the tensioning force. The design of the T-shaped boss and T-shaped keyway allows the expansion pin to be retracted and reset during the upward movement of the pull block, thereby ensuring the cyclic tensioning and fixing of the workpiece.

[0015] Preferably, an anti-slip thread is provided on the outer side of the rising pin.

[0016] In this solution, by providing anti-slip threads on the outer surface of the rising pin, the reliability of positioning and locking the workpiece is further improved.

[0017] Preferably, two second oil cylinders are provided, and two sets of locking and positioning components are provided correspondingly, and the arrangement positions of the two sets of locking and positioning components correspond to the positions of the cylinder holes at both ends of the engine cylinder workpiece.

[0018] In this solution, by providing two second oil cylinders and two sets of locking and positioning components, locking and positioning can be performed through the cylinder holes at both ends of the engine cylinder workpiece, which makes it more stable.

[0019] Preferably, a guide rail is provided on the base, sliders are provided on both sides of the base plate, and the base plate and the base are slidably connected through the sliders and the guide rails; a first door-type frame is installed on the base; a third oil cylinder is installed on the base, and the third oil cylinder is connected to the base plate to push the base plate to slide along the guide rails; a plurality of second slag bag removal members are respectively installed on the inner side of the first door-type frame to remove the slag bags on the side of the engine cylinder workpiece; a plurality of proximity switches are installed under the base to control the stroke of the third oil cylinder.

[0020] In this solution, the bottom plate can slide relative to the base via guide rails and sliders. Once locked and positioned, the bottom plate's relative position on the base can be controlled by a third oil cylinder and proximity switches, enabling the removal of slag from various surfaces. A second slag removal member, mounted on the first portal frame, removes slag from the side of the engine block workpiece. Specifically, the second slag removal member comprises long, blade-like strips of varying lengths, arranged sequentially from top to bottom on the inside of one column of the first portal frame. It also comprises a slag removal plate with an irregular side surface, arranged on the inside of another column of the first portal frame, thereby matching the slag on one side of the engine block workpiece.

[0021] Preferably, the automobile engine cylinder block slag removal device also includes: a buffer, which is installed on the base through a buffer bracket, and the buffer is arranged in cooperation with the third oil cylinder; and an anti-collision block, which is installed on the buffer bracket, and the anti-collision block is opposite to the bottom plate.

[0022] In this solution, the design of the buffer and anti-collision block ensures the stability of the third oil cylinder when pushing and pulling the base plate to move the engine cylinder workpiece.

[0023] Preferably, the automobile engine block slag bag removal equipment also includes: a second portal frame, installed on the base, the second portal frame is opposite to the first portal frame; a plurality of third slag bag removal members, respectively installed on the inner side of the second portal frame to remove the slag bags on the side of the engine cylinder workpiece; a fourth oil cylinder, installed above the crossbeam of the second portal frame, the pull rod head of the fourth oil cylinder passes through the crossbeam and is connected to the first slag bag pressure plate; the second slag bag pressure plate is connected to the bottom end of the guide rod, the top end of the guide rod passes through the crossbeam, the second slag bag pressure plate and the first slag bag pressure plate are arranged on the left and right and fixedly connected to remove the large slag bags of vertical ribs extending from the side of the engine cylinder workpiece.

[0024] In this solution, the fourth oil cylinder drives the first and second slag pack pressure plates, which cooperate with the third slag pack removal member to remove the slag pack on the other side of the engine block workpiece. The third slag pack removal member includes slag pack removal plates with irregular side surfaces, which are respectively arranged on the inner sides of the two columns of the second door-shaped frame to match the slag pack on the other side of the engine block workpiece. The first and second slag pack pressure plates can first break the slag pack rib plates in the large slag pack extending from the other side of the engine block workpiece, thereby removing the entire slag pack and then retreating, effectively removing the large slag pack extending from the other side of the engine block workpiece.

[0025] Preferably, the first slag pack pressure plate is in a wrench shape with an opening facing downward, and the second slag pack pressure plate is in a rectangular parallelepiped shape.

[0026] In this solution, the first slag bag pressure plate is designed to be a wrench with the opening downward, and the second slag bag pressure plate is designed to be a rectangular parallelepiped, which makes it easy to remove the entire slag bag after breaking the slag bag ribs without damaging the workpiece.

[0027] Preferably, the automobile engine block slag removal device further comprises: a slag blowing device, which is arranged in the middle position of the workpiece placement plate; and a guide cover, which is installed above the sliders on both sides of the base plate.

[0028] In this solution, by setting up a slag blowing device and a guide cover, the removed slag bag can be easily flowed away, avoiding the accumulation of slag bags affecting the slag bag removal action of the next workpiece, so that the entire device can continue to cycle and improve the slag bag removal efficiency.

[0029] The automobile engine cylinder block slag removal device proposed by the present invention has the following beneficial technical effects:

[0030] (1) The automobile engine cylinder block slag removal device proposed in the present invention can stably remove slag, shorten the production cycle, improve work efficiency, and improve product quality.

[0031] (2) Compared with the conventional method of using a manipulator to grab a workpiece and hit the slag bag, the slag bag removal device proposed in the present invention has accurate positioning, reliable locking, and is less likely to cause deviation in the collision position, thus ensuring the accuracy of slag bag removal.

[0032] (3) The unique design of the locking and positioning assembly in the automobile engine cylinder block slag removal equipment proposed by the present invention makes the positioning and locking of the workpiece more secure and can realize automatic operation.

[0033] (4) The present invention proposes an automobile engine cylinder block slag removal device that works independently. After the manipulator puts down the workpiece, it can perform other actions, thereby separating the slag removal time from the process, allowing the slag removal process to be carried out simultaneously with other processes, reducing the mold waiting time, shortening the casting time, and greatly improving production efficiency.

DETAILED DESCRIPTION

[0049] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0050] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0051] The following combination Figures 1 to 11 The slag removal device for an automobile engine cylinder block according to an embodiment of the present invention will be described in detail.

[0052] like Figures 1 to 10As shown, the automotive engine block slag removal equipment according to an embodiment of the present invention includes: a base 102, a bottom plate 104, a workpiece placement plate 106, a first hydraulic cylinder 108, a second hydraulic cylinder 112, a locking and positioning assembly 116, and first slag removal components 118. The base 102 and bottom plate 104 are coupled together, with the center region between the base 102 and bottom plate 104 being hollowed out. The workpiece placement plate 106 is positioned within the hollowed-out center region of the bottom plate 104. The first hydraulic cylinder 108 is connected to the workpiece placement plate 106 and fixedly mounted below the bottom plate 104 via a mounting bracket 110. The first hydraulic cylinder 108 drives the workpiece placement plate 106 up and down, striking the multiple first slag removal components 118 mounted on the bottom plate 104, thereby removing the slag 2022 surrounding the cylinder bore of the engine block workpiece 202. This allows the robot to place the engine block workpiece 202 to be desmeared and proceed to perform other operations, significantly reducing mold waiting time. A second oil cylinder 112 is mounted below the workpiece placement plate 106. A pull rod 114 of the second oil cylinder 112 passes through the workpiece placement plate 106 and connects to a locking and positioning assembly 116 mounted on the workpiece placement plate 106. The second oil cylinder 112 cooperates with the locking and positioning assembly 116 to lock the workpiece, ensuring stable placement and precise positioning, while also preventing positional deviation due to impact. Multiple first slag removal members 118 are mounted on the base plate 104. These members are positioned around the workpiece placement plate 106 and are used to remove slag 2022 from the cylinder bore of the engine block workpiece 202. These members 118 include slag removal plates with downwardly inclined outer surfaces forming a cutting edge, and a slag removal push rod with a cutting edge at its top. The slag removal plates and push rod are positioned to align with the slag 2022 surrounding the cylinder bore of the engine block workpiece 202.

[0053] Furthermore, if Figures 1 to 10As shown, the locking and positioning assembly 116 includes a positioning plate 1162, a pin 1164, a pressure cap 1166, and a pull block 1168. The positioning plate 1162 is mounted on the workpiece placement plate 106. The positioning plate 1162 aligns with the cylinder bore of the automobile engine block workpiece 202, providing preliminary positioning for the workpiece. The pin 1164 is mounted on the positioning plate 116, and the pull block 1168 is mounted atop the pin 1164. The outer side of the pull block 1168 is slidably connected to the inner side of the pin 1164. The pull block 1168 is connected to the pull rod 114 of the second oil cylinder 112. When the pull rod 114 of the second oil cylinder 112 is tightened, the pull block 1168 is driven downward, gradually increasing the diameter of the pin 1164. When the pin 1164 encounters the workpiece, the tensioning force locks the workpiece securely in place, ensuring a secure hold and preventing dislocation from impact, thereby ensuring accurate slag removal. A pressure cover 1166 is sleeved on the rising pin 1164 , and the pressure cover 1166 is fixedly connected to the positioning plate 1162 , which can limit the moving direction of the rising pin 1164 and further ensure the accuracy of the tightening positioning.

[0054] Further, as 6 to Figure 9 As shown, the pull block 1168 includes an inverted quadrangular pyramid body 1168-1 with a connection hole in the middle, which is wide at the top and narrow at the bottom, and a T-shaped protrusion 1168-2 arranged on the side of the inverted quadrangular pyramid body 1168-1. The cross-sectional area of the T-shaped protrusion 1168-2 decreases from top to bottom. The inverted quadrangular pyramid body 1168-1 is fixedly connected to the pull rod 114 of the second oil cylinder 112. The rising pin 1164 is surrounded by four sector-shaped bodies 1164-1, which are cylindrical with an inverted quadrangular pyramid-shaped through groove in the middle. There is a gap between two adjacent sector-shaped bodies 1164-1. Each sector-shaped body 1164-1 has a T-shaped keyway 1164-2. The cross-sectional area of the T-shaped keyway 1164-2 decreases from top to bottom. When the machine is stopped, the lower part of the T-shaped protrusion 1168-2 is stuck in the T-shaped groove. With this design, the diameter of the expansion pin 1164 can gradually increase during the downward movement of the pulling block 1168, and the workpiece can be fixed by the tensioning force. The design of the T-shaped boss 1168-2 and the T-shaped keyway 1164-2 allows the expansion pin 1164 to be retracted during the upward movement of the pulling block 1168, so that the expansion pin 1164 is reset, thereby ensuring the cyclic tensioning and fixing of the workpiece.

[0055] Furthermore, if Figure 6 As shown, an anti-slip thread 1164-3 is provided on the outer surface of the rising pin 1164, which further improves the reliability when positioning and locking the workpiece.

[0056] Furthermore, if Figures 1 to 5As shown, the automobile engine block slag removal device is provided with two second oil cylinders 112 and two corresponding sets of locking and positioning assemblies 116. The two sets of locking and positioning assemblies 116 are arranged at positions corresponding to the cylinder holes at both ends of the engine block workpiece 202. The locking and positioning can be achieved through the cylinder holes at both ends of the engine block workpiece 202, which provides greater stability.

[0057] Furthermore, if Figures 1 to 5 As shown, guide rails are provided on the base 102, and sliders are provided on both sides of the bottom plate 104. The bottom plate 104 and the base 102 are slidably connected via the sliders and guide rails. A third oil cylinder is installed on the base 102 and connected to the bottom plate 104, pushing the bottom plate 104 to slide along the guide rails, thereby achieving left and right movement of the engine cylinder workpiece 202. After a single locking and positioning, the relative position of the bottom plate 104 on the base 102 can be controlled by the third oil cylinder and proximity switches 130 to achieve the removal of slag bags 2022 from various surfaces. Multiple proximity switches 130 are installed below the base 102 to control the stroke of the third oil cylinder, thereby controlling the position of the engine cylinder workpiece 202 and improving the stability of slag bag removal. A first door-shaped frame is installed on the base 102, and a plurality of second slag bag removal members are respectively installed on the inner side of the first door-shaped frame to remove the slag bag 2022 on the side of the engine cylinder workpiece 202. The second slag bag removal members include long strips with blade-shaped sides, which are of different lengths and are arranged from top to bottom on the inner side of a column of the first door-shaped frame. The second slag bag removal members also include a slag bag removal plate with irregular side shapes and are arranged on the inner side of another column of the first door-shaped frame, so as to match the slag bag on one side of the engine cylinder workpiece 202.

[0058] Furthermore, if Figures 1 to 5 As shown, a buffer 132 is installed on the base 102 through a buffer bracket 134. The buffer 132 is arranged in conjunction with the third oil cylinder. At the same time, an anti-collision block (not marked in the figure) opposite to the bottom plate 104 is installed on the buffer bracket 134. This design ensures the stability of the third oil cylinder when pushing and pulling the bottom plate 104 to move the engine cylinder workpiece 202.

[0059] Furthermore, if Figures 1 to 5As shown, a second portal frame 136 is mounted on the base 102, opposite the first portal frame. A fourth oil cylinder 140 is mounted above the crossbeam 1362 of the second portal frame 136. The end of the pull rod 114 of the fourth oil cylinder 140 passes through the crossbeam 1362 and connects to the first slag pack pressure plate 142. A second slag pack pressure plate 144 is connected to the bottom end of a guide rod 146, the top end of which passes through the crossbeam 1362. The second slag pack pressure plate 144 is positioned on the left and right sides of the first slag pack pressure plate 142 and is fixedly connected. The first and second slag pack pressure plates 142 and 144 can first break the slag pack ribs 2024 in the large slag pack extending from the other side of the engine block workpiece 202, thereby removing the entire slag pack 2022 and then retracting, effectively removing the large slag pack extending from the other side of the engine block workpiece 202. A plurality of third slag bag removal members 138 are also installed on the inner side of the second door-type frame 136. The third slag bag removal members 138 include slag bag removal plates with irregular side surfaces, which are respectively arranged on the inner sides of two columns of the second door-type frame 136, and matched with the slag bag 2022 on the other side of the engine cylinder workpiece 202, thereby removing the slag bag on the other side of the engine cylinder workpiece 202.

[0060] Furthermore, if Figures 1 to 4 As shown, the first slag ladle pressing plate 142 is wrench-shaped with its opening facing downward, and the second slag ladle pressing plate 144 is rectangular, which facilitates breaking the slag ladle ribs 2024 without damaging the workpiece.

[0061] Furthermore, if Figures 1 to 5 As shown, the automobile engine block slag removal apparatus is also equipped with a slag blowing device 148 and a deflector 150. The slag blowing device 148 is located in the middle of the workpiece placement plate 106, and the deflector 150 is installed above the sliders on both sides of the base plate 104. This facilitates the removal of the removed slag, preventing slag accumulation from affecting the slag removal operation of the next workpiece. This allows the entire apparatus to operate continuously in a cycle, improving the efficiency of slag removal.

[0062] The working process of the automobile engine cylinder block slag removal device proposed by the present invention is as follows:

[0063] Under the coordination of electrical and hydraulic, the third oil cylinder pushes the bottom plate 104 to move along the guide rail, and the bottom plate 104 is fixed in the middle position through the middle proximity switch 130; the manipulator places the engine cylinder workpiece 202 on the workpiece placement plate 106, and the engine cylinder workpiece 202 is as shown in FIG.
