Description

Technical Field

[0001] This invention relates to the field of automotive engine block repair technology, specifically to an integrated repair equipment for automotive engine block remanufacturing involving spraying and fine grinding. Background Technology

[0002] Automotive engine cylinder block spraying and fine grinding repair is a technology for repairing damage such as wear and corrosion of engine cylinder blocks. It aims to restore the dimensional accuracy and surface quality of the cylinder block and extend the service life of the engine. It mainly involves forming a wear-resistant coating on the surface of the cylinder block through a spraying process, followed by fine grinding to restore the dimensional accuracy and surface quality of the cylinder block. However, existing integrated repair equipment has the following problems when used. When repairing the inside of the piston chamber of a cylinder block, lubricating coolant is usually sprayed during the grinding process to ensure smooth grinding and reduce the adverse effects of high temperatures. However, existing integrated repair equipment is not convenient for uniform lubrication and cooling. Most of them rely on point-to-point spraying, which can only lubricate and cool a single point. This can easily lead to uneven lubrication and cooling across the entire grinding area of ​​the inner wall, affecting the internal grinding accuracy. At the same time, different car engine cylinder blocks have different piston chamber diameters and positions. Existing integrated repair equipment is not convenient to adapt to different specifications of car engine cylinder blocks through simple adjustments. It usually requires replacing the grinding and spraying mechanism, which is not only cumbersome but also increases equipment costs.

[0003] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated spraying and grinding repair device for remanufacturing automobile engine blocks, so as to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated spraying and grinding repair equipment for remanufacturing automobile engine cylinder blocks, comprising a base, a positioning mechanism installed on the top guide rail of the base for positioning and fixing the engine cylinder block, a mounting seat connected to the top bracket of the base via a hydraulic cylinder, and a guide seat connected to the bottom of the mounting seat via an embedded motor; It also includes a bidirectional lead screw, which is installed at the bottom of the guide seat by a motor rotating laterally. Two drive seats are threaded on the bidirectional lead screw. An installation head is fixed at the bottom of the drive seat. An installation column is installed through the installation head and the drive seat. A drive assembly is provided between the installation column and the drive seat. A repair plate is connected to the outer cavity of the installation column by a crossbar. A grinding strip and a nozzle are fixed to the outer side of the repair plate below the two drive seats, respectively. A liquid guide plate is fixed to the side of the repair plate where the grinding strip is located. A liquid delivery assembly is disposed between the mounting head and the repair plate where the nozzle is located, and is used to deliver spraying liquid to the nozzle; An adjustment assembly, disposed between the guide seat and the mounting post, is used to adjust the position of the repair plate according to the distance between the two drive seats.

[0006] Preferably, the drive seat slides against the bottom of the guide seat via a bidirectional lead screw, and the two drive seats move in opposite directions.

[0007] Preferably, the liquid guide plate is designed as a hook-shaped structure when viewed from above, the internal space of the liquid guide plate is inclined inward in the side, and the front end of the liquid guide plate has inclined liquid outlet holes distributed vertically at equal intervals.

[0008] Preferably, the drive assembly includes a gear, which is embedded in the drive housing via a motor, and a gear sleeve meshes with the inner side of the gear, the gear sleeve being fixedly fitted onto the top of the mounting post.

[0009] Preferably, the liquid delivery assembly includes a liquid delivery tray and a liquid delivery box. The liquid delivery tray is fixed to the bottom of the mounting head, and the liquid delivery box is rotatably and sealed on the liquid delivery tray. The liquid delivery box is connected to the nozzle through a corrugated pipe that penetrates the repair plate.

[0010] Preferably, the adjusting assembly includes a toothed roller, which is movably disposed in the bottom cavity of the guide seat. A rack is engaged with the rear side of the toothed roller. The rack is vertically movably mounted in the bottom cavity of the guide seat via an electric push rod. A guide post is fixedly fixed to the bottom of the toothed roller. The guide post is embedded and rotatably mounted in a mounting post. A guide plate is fixedly sleeved on the guide post. A guide groove is formed on the top of the guide plate. A guide rod is slidably disposed in the guide groove. The guide rod is fixed to the bottom of the crossbar.

[0011] Preferably, the guide groove is designed with an inclined arc shape on the guide plate, and the guide groove drives the crossbar to move laterally through the rotation of the guide plate.

[0012] Preferably, the guide discs inside the two mounting columns are mirrored, and the movement and rotation of the two toothed rollers drive the repair plates on the outer sides of the two mounting columns to move synchronously.

[0013] Compared with the prior art, the beneficial effects of the present invention are: In this invention, during grinding, lubricating coolant is sprayed into the piston cavity and enters the internal area of ​​the guide plate. Under centrifugal force, the liquid is thrown to the front end of the guide plate and discharged from its front outlet to the inner wall of the piston cavity. The rotating guide plate evenly throws the liquid onto the inner wall of the piston cavity, providing circumferential lubrication and cooling. Because the front outlet of the guide plate is designed with equally spaced inclined distribution, combined with its rotation and up-and-down movement, it further helps the liquid to be evenly distributed in the piston cavity. Compared with traditional single-point spraying, the simple use of the guide plate can greatly improve lubrication and cooling efficiency, improve grinding efficiency and service life. Furthermore, when adjusting the position of the repair plate for piston cavities of different sizes, the inwardly inclined guide plate can still effectively receive the lubricating coolant, further improving the applicability of the device. This invention addresses the issue that, for piston chambers of different specifications, the internal diameter of the piston chamber and the center distance between adjacent piston chambers vary. By using a bidirectional lead screw to drive two drive seats to move in opposite directions, the distance between the two mounting posts can be adjusted. Simultaneously, through the meshing of toothed rollers and gears, the guide plate is rotated, and the guide groove and guide rod drive the crossbar and repair plate to move, allowing for synchronous adjustment of the repair plate's position. This ensures that, for piston chambers of different specifications, only the distance between the two drive seats needs to be adjusted to guarantee alternating positioning operations for spraying and polishing the piston chamber, while simultaneously ensuring the repair and polishing effect inside the piston chamber.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-7 The present invention provides a technical solution: an integrated repair equipment for spraying and grinding of automobile engine cylinder block remanufacturing, including a base 1, a positioning mechanism installed on the top guide rail of the base 1 for positioning and fixing the engine cylinder block, a mounting seat 4 connected to the top bracket 2 of the base 1 through a hydraulic cylinder 3, and a guide seat 5 connected to the bottom of the mounting seat 4 through an embedded motor. In one embodiment of the present invention, a bidirectional lead screw 6 is installed at the bottom of a guide seat 5 via a motor that rotates laterally. Two drive seats 7 are threaded onto the bidirectional lead screw 6. An installation head 8 is fixed at the bottom of the drive seat 7. An installation column 9 is installed through the installation head 8 and the drive seat 7. A drive assembly is provided between the installation column 9 and the drive seat 7. A repair plate 11 is connected to the outer cavity of the installation column 9 via a crossbar 10. A grinding strip and a nozzle are fixed to the outer side of the repair plate 11 below the two drive seats 7, respectively. A liquid guide plate 111 is fixed to the side of the repair plate 11 where the grinding strip is located. The drive seats 7 slide against the bottom of the guide seat 5 via the bidirectional lead screw 6, and the two drive seats 7 move in opposite directions. The drive assembly includes a gear 121. The gear 121 is embedded in the drive seat 7 via a motor. A gear sleeve 122 meshes with the inner side of the gear 121. The gear sleeve 122 is fixedly sleeved on the top of the installation column 9. The motor inside the mounting base 4 drives the guide seat 5 to rotate, placing the mounting post 9 of the nozzle above the piston cavity. An external spray pump connects to the liquid delivery plate 131, allowing the repair fluid to enter the liquid delivery tank 132 and be sprayed onto the inner wall of the piston cavity through the bellows. Simultaneously, the motor inside the drive base 7 drives the gear 121 to rotate, which in turn drives the mounting post 9 to rotate, causing the nozzle to follow the repair plate 11. This, combined with the hydraulic cylinder 3 driving the mounting base 4 up and down, provides uniform spraying and repair to the piston cavity. Then, the hydraulic cylinder 3 drives the mounting head 8 and mounting post 9 to reset, and the motor again drives the guide seat 5 to rotate the mounting post 9 with the grinding strip onto the previously sprayed and repaired piston cavity. The hydraulic cylinder 3 is then driven again, causing the repair plate 11 with the grinding strip to enter the piston cavity. The motor-driven gear 121 rotates, causing the mounting post 9 and repair plate 11 to rotate, thus grinding the inner wall of the piston cavity.

[0018] In one embodiment of the present invention, a liquid delivery assembly is disposed between the mounting head 8 and the repair plate 11 where the nozzle is located, for delivering spraying liquid to the nozzle; the liquid delivery assembly includes a liquid delivery tray 131 and a liquid delivery tank 132, the liquid delivery tray 131 is fixed to the bottom of the mounting head 8, and the liquid delivery tank 132 is rotatably and sealed on the liquid delivery tray 131, and the liquid delivery tank 132 is connected to the nozzle through a corrugated pipe penetrating the repair plate 11; An external spray pump is connected to the delivery plate 131, allowing the repair fluid to enter the delivery tank 132 and be sprayed from the nozzle to the inner wall of the piston chamber through the bellows. When the mounting column 9 rotates, the bellows drives the delivery tank 132 to rotate, and the delivery tank 132 rotates in a sealed manner on the delivery plate 131 to deliver fluid stably.

[0019] In one embodiment of the present invention, an adjustment assembly is disposed between the guide seat 5 and the mounting post 9, for adjusting the position of the repair plate 11 according to the distance between the two drive seats 7; the adjustment assembly includes a toothed roller 141, which is movably disposed in the bottom cavity of the guide seat 5, and a rack 142 meshes with the rear side of the toothed roller 141. The rack 142 is vertically movably mounted in the bottom cavity of the guide seat 5 via an electric push rod. A guide post 143 is fixed to the bottom of the toothed roller 141, and the guide post 143 is rotatably embedded in the mounting post 9. A guide plate 144 is fixedly sleeved on the guide post 143. A guide groove 145 is opened on the top of the guide plate 144. A guide rod 146 is slidably arranged in the guide groove 145. The guide rod 146 is fixed to the bottom of the crossbar 10. The guide groove 145 has an inclined arc structure design on the guide plate 144. The guide groove 145 drives the crossbar 10 to move laterally through the rotation of the guide plate 144. The guide plates 144 in the two mounting posts 9 are mirrored. The movement and rotation of the two toothed rollers 141 drive the repair plates 11 on the outside of the two mounting posts 9 to move synchronously. Based on the size and spacing of the piston chambers in the automobile engine cylinder block, the bidirectional lead screw 6 is rotated by a motor to adjust the distance between the two drive seats 7, and then adjust the distance between the two mounting posts 9. At the same time, the movement of the drive seats 7 drives the toothed roller 141 to move. Through the meshing of the toothed roller 141 with the rack 142, the guide post 143 connected to the toothed roller 141 is driven to rotate. The guide post 143 drives the guide plate 144 to rotate. Through the guide groove 145, the guide rod 146 is moved, and then through the crossbar 10, the repair plate 11 is rotated. The position of the grinding strip and the nozzle on the repair plate 11 is adjusted so that the grinding strip and the nozzle are adapted to piston chambers with different inner diameters.

[0020] In one embodiment of the present invention, the liquid guide plate 111 is designed as a hook-shaped structure from a top view. The internal space of the liquid guide plate 111 is inclined inward from the side. Inclined liquid outlet holes are distributed vertically at equal intervals at the front end of the liquid guide plate 111. Through an external liquid spraying mechanism, lubricating coolant is sprayed into the piston cavity. The liquid is sprayed into the liquid guide plate 111. Under the action of centrifugal force, the liquid is thrown to the front end and sprayed out from the liquid outlet holes at the front end of the liquid guide plate 111 to the inner wall of the piston cavity, so as to lubricate and cool during grinding.

[0021] Working principle: First, the car engine block is fixed on the base 1 by the positioning mechanism, so that the piston chamber of the car engine block is located below the mounting column 9. Then, according to the size and spacing of the piston chamber of the car engine block, the bidirectional lead screw 6 is rotated by the motor to adjust the distance between the two drive seats 7, and then adjust the distance between the two mounting columns 9. At the same time, the movement of the drive seats 7 drives the toothed roller 141 to move. Through the meshing of the toothed roller 141 and the rack 142, the guide column 143 connected to the toothed roller 141 is driven to rotate. The guide column 143 drives the guide plate 144 to rotate. Through the guide groove 145, the guide rod 146 is moved, and then through the crossbar 10, the repair plate 11 is rotated. The position of the grinding strip and the nozzle on the repair plate 11 is adjusted so that the grinding strip and the nozzle are adapted to the piston chambers with different inner diameters. After the adjustment is completed, the rack 142 is moved upward by the electric push rod so that the rack 142 does not contact the toothed roller 141, ensuring that the toothed roller 141 follows the rotation of the mounting column 9. First, the motor inside the mounting base 4 drives the guide seat 5 to rotate, positioning the mounting post 9 of the nozzle above the piston cavity. An external spray pump connects to the delivery plate 131, allowing the repair fluid to enter the delivery tank 132 and be sprayed through the bellows onto the inner wall of the piston cavity. Simultaneously, the motor inside the drive base 7 drives the gear 121 to rotate, which in turn drives the mounting post 9 to rotate, causing the nozzle to follow the repair plate 11. This, combined with the hydraulic cylinder 3 moving the mounting base 4 up and down, provides uniform spraying repair to the piston cavity. Then, the hydraulic cylinder 3 drives the mounting head 8 and mounting post 9 to reset, and the motor again drives the guide seat 5 to rotate, positioning the mounting post 9 with the grinding strip in the previously sprayed repair area. Above the piston chamber, the hydraulic cylinder 3 is driven again, causing the repair plate 11, which is equipped with a grinding strip, to enter the piston chamber. The motor drives the gear 121 to rotate, which in turn drives the mounting column 9 and the repair plate 11 to rotate, grinding the inner wall of the piston chamber. At the same time, through an external spraying mechanism, lubricating coolant is sprayed into the piston chamber. The liquid is sprayed into the guide plate 111, and under the action of centrifugal force, the liquid is thrown to the front end and sprayed out from the liquid outlet at the front end of the guide plate 111 to the inner wall of the piston chamber, providing lubrication and cooling during grinding. Then, the hydraulic cylinder 3 drives the mounting column 9 and the repair plate 11, and through the guide rail and positioning mechanism, drives the car engine block to move, repeating the above operation to spray and grind the next piston chamber.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
