Description

Technical Field

[0001] This invention relates to the field of robotics, specifically to a robot for machining engine cylinder blocks. Background Technology

[0002] Robots (i.e., robotic arms) are specialized actuators used in the machining, transfer, and loading / unloading of engine cylinder blocks to grasp, position, and clamp them. In the machining and automated production line industry, they are collectively referred to as engine cylinder block-specific tooling fixtures, also commonly known as mechanical manual fixtures, cylinder block clamping fixtures, or rigid positioning fixtures. These fixtures are generally made of hard metals such as cast iron, hardened steel, and cemented carbide because engine cylinder blocks are heavy, precision workpieces with large weight and micron-level machining accuracy requirements. Hard materials possess extremely high structural rigidity, resistance to deformation, and wear resistance, ensuring that the cylinder block will not shift, shake, or flip during high-speed transfer and machine tool processing, accurately matching the positioning reference of the processing equipment. They can also withstand long-term, high-frequency clamping operations without wear or deformation, thus meeting the stability and precision requirements of large-scale, continuous production.

[0003] However, using cylinder block jigs made of purely rigid materials also presents significant application drawbacks and potential hazards. Because the jig and cylinder block have a rigid, direct contact without any cushioning, the rigid contact surface of the jig directly squeezes and rubs against critical precision parts of the engine cylinder block, such as the machined surfaces, assembly mating surfaces, and locating stops, under the clamping force. This easily causes indentations, scratches, dents, and even localized micro-deformations on the cylinder block surface. Such damage not only compromises the dimensional accuracy and surface finish of the cylinder block but also severely affects the assembly sealing and fitting precision of the cylinder block with core components such as the cylinder head and crankshaft. At best, this requires additional grinding and repair processes, increasing production costs; at worst, it can directly lead to cylinder block scrapping, reducing the yield rate and affecting the final assembly quality and operational reliability of the engine. Therefore, to address these issues, a robot for machining engine cylinder blocks is proposed. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes a robot for machining engine cylinder blocks.

[0005] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a robot for machining engine cylinder blocks, including a manipulator and a fixture mounted on the manipulator, wherein the fixture is provided with two clamping plates controlled by a drive mechanism; it also includes: a lifting mechanism, including two servo motors mounted in the clamping plates, wherein a lead screw is fixedly mounted on the output end of the servo motor, and a movable block is movably connected to the lead screw; a fixed frame, fixedly mounted on the movable block and having an electric push rod fixedly mounted inside, wherein a lifting column with a rubber collar is fixedly mounted on the output end of the electric push rod, and a sensor is fixedly mounted on one end of the lifting column.

[0006] Furthermore, rubber auxiliary blocks are fixedly installed on the sides of the two clamps that are close to each other.

[0007] Furthermore, the electric push rod is provided with a support mechanism, which includes several connecting frames fixedly connected to the electric push rod. A sliding plate fixedly connected to the lifting column is slidably connected inside the connecting frame. A stop bar made of flexible material is provided on the lifting column. A support block that slides within the clamping plate is fixedly installed on one side of the movable block.

[0008] Furthermore, the clamping plate is provided with two multi-stage telescopic plates, one end of the two multi-stage telescopic plates is fixedly connected to the inner wall of the clamping plate, and the ends of the two multi-stage telescopic plates that are close to each other are fixedly connected to the fixed frame; the multi-stage telescopic plates are composed of several hollow plates that are slidably connected.

[0009] Furthermore, a liquid spraying mechanism is provided inside the clamping plate. The liquid spraying mechanism includes two symmetrically arranged liquid storage boxes made of rubber inside the clamping plate. One side of each liquid storage box is fixedly installed with an inlet pipe that communicates with the interior and has a one-way valve. The other side of each liquid storage box is fixedly installed with an outlet pipe that communicates with the interior and has a one-way valve. Extrusion blocks are provided on both sides of the support block.

[0010] Furthermore, several inclined spray pipes are fixedly installed at the bottom of the fixed frame, and the end of the outlet pipe away from the liquid storage box is connected to several spray pipes.

[0011] Furthermore, one end of the extrusion block is arc-shaped, and several rolling columns are rotatably connected to the arc-shaped surface of the extrusion block.

[0012] Furthermore, the extrusion block slides within the support block via an elastic rope, and a first electromagnet is fixedly installed within the support block, while a second electromagnet is fixedly installed on one side of the extrusion block.

[0013] Furthermore, the clamp is provided with a stirring mechanism, which includes a deformable and hollow elastic block; a connecting pipe is fixedly installed in the liquid storage box, and a sliding rod is slidably connected in the connecting pipe. A connecting plate is fixedly installed at one end of the sliding rod, and a plurality of fan blades are provided at one end of the connecting plate; the connecting pipe and the elastic block are connected by a conduit.

[0014] Furthermore, the multi-stage telescopic plate is provided with an air blowing mechanism, which includes an air inlet pipe with a one-way valve and connected to the interior of the multi-stage telescopic plate. An air outlet pipe with a one-way valve and connected to the interior is fixedly installed on the surface of the multi-stage telescopic plate, and one end of the air outlet pipe is connected to the interior of the spray pipe. The several hollow plates of the multi-stage telescopic plate are sealed and slidably connected, and the several hollow plates are connected through through holes.

[0015] The advantages of this invention are: 1. This invention revolutionizes the traditional design of directly clamping and lifting engine blocks through structural design. It utilizes a lifting column and a collar to lift the engine block by engaging with a pre-drilled hole, thus adapting to different types of engine blocks and ensuring a consistent contact area during lifting. The collar, made of rubber, provides cushioning and protection for the engine block, while the auxiliary block design prevents easy wobbling during lifting, ensuring stability. The flexible material design effectively prevents indentations, scratches, and impacts on the engine block surface caused by rigid contact, thereby avoiding damage to the engine block and subsequent repairs.

[0016] 2. This invention, through its designed structure, sprays lubricating oil before the engine block is clamped by the rubber auxiliary block. This allows a thin and uniform lubricating barrier film to quickly form between the precision contact surface of the cylinder block and the rubber clamping surface. This effectively prevents direct friction and compression during clamping, thus avoiding scratches, indentations, or marks on the machined surface of the cylinder block. It reduces friction and localized stress at the contact points, minimizing microscopic damage to the cylinder block surface. Furthermore, it helps to adsorb hard impurities such as fine dust and iron filings from the air or workpiece surface, preventing these impurities from being trapped between the clamping plate and the cylinder block and causing secondary impact damage. This maximizes the protection of the cylinder block's surface precision and smoothness, while also improving the smoothness and stability of the rubber clamping mechanism, ensuring that the cylinder block is not damaged during transport and processing due to clamping actions.

[0017] 3. This invention utilizes a designed agitation mechanism to periodically agitate and mix the lubricating oil in the reservoir. This is because engine-specific lubricating oils contain composite additives for lubrication, film formation, and rust prevention. Issues such as sedimentation of active ingredients, uneven concentration, and even oil-water separation can occur. Therefore, periodic agitation ensures thorough and uniform mixing of all oil components, guaranteeing the formation of a stable and uniform protective film on the cylinder block surface after spraying. Simultaneously, it keeps fine iron filings, dust, and other impurities mixed in with the oil suspended, preventing sedimentation and clogging of the spray lines and nozzles. Furthermore, it prevents localized oxidation and deterioration of the oil due to prolonged stagnation, consistently ensuring stable lubrication, isolation, and protective performance, and guaranteeing reliable protection of the cylinder block's precision contact surfaces.

[0018] 4. Through its designed structure, this invention allows for pre-blowing of the engine cylinder block before lubricating oil is sprayed. This pre-blowing removes impurities such as iron filings and dust from the contact surface between the cylinder block and the rubber clamping plate, preventing these impurities from scratching the precision contact surface of the cylinder block during clamping and providing a clean surface foundation for subsequent oil spraying. Blowing the air after lubricating oil spraying ensures the oil is evenly dispersed and spread, forming a continuous, thin, and stable lubricating protective film in the contact area. Simultaneously, it removes excess liquid, ensuring the protective effect of the oil film without affecting the clamping friction and positioning stability of the rubber clamping plate.

[0022] 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.

[0023] Please see Figure 1-8 As shown, a robot for machining engine cylinder blocks includes a robotic arm 1 and a gripper 2 mounted on the robotic arm 1. The gripper 2 has two clamping plates 3 controlled by a drive mechanism. It also includes a lifting mechanism 10, comprising two servo motors 11 mounted within the clamping plates 3. A lead screw 12 is fixedly mounted on the output end of each servo motor 11, and a movable block 13 is movably connected to the lead screw 12. A fixed frame 14 is fixedly mounted on the movable block 13 and has an electric push rod 15 fixedly mounted inside. A lifting column 16 with a rubber collar 17 is fixedly mounted on the output end of the electric push rod 15, and a sensor 18 is fixedly mounted on one end of the lifting column 16. Rubber auxiliary blocks 70 are fixedly mounted on the sides of the two clamping plates 3 that are close to each other.

[0024] Specifically, the electric push rod 15 is equipped with a support mechanism 20, which includes several connecting frames 21 fixedly connected to the electric push rod 15. Inside each connecting frame 21, a sliding plate 22 fixedly connected to a lifting column 16 is slidably connected. A flexible stop bar 24 is provided on the lifting column 16. A support block 23 that slides within the clamping plate 3 is fixedly installed on one side of the movable block 13. Two multi-stage telescopic plates 30 are provided inside the clamping plate 3. One end of each multi-stage telescopic plate 30 is fixedly connected to the inner wall of the clamping plate 3, and the ends of the two multi-stage telescopic plates 30 that are close to each other are fixedly connected to the fixed frame 14. Each multi-stage telescopic plate 30 is composed of several hollow plates slidably connected together.

[0025] During operation, when the engine block is being processed and transferred, a robotic arm 1 is used. The robotic arm 1 moves the clamp 2 and clamping plates 3 to the engine block, positioning the two clamping plates 3 on either side of the engine block. At this point, the servo motor 11 within the clamping plates 3 is activated. The lead screw 12 of the servo motor 11 moves the movable block 13 and the fixed frame 14 up and down. As the fixed frame 14 moves, it also moves components such as the lifting column 16, the collar 17, and the sensor 18. The sensor 18 positions the lifting column 16 at the hole in the engine block, sending a signal to the controller to stop the servo motor 11, ensuring that the lifting column 16 and the collar 17 are aligned with the hole in the engine block. Then, the electric push rod 15 within the fixed frame 14 is activated, allowing it to move the lifting column 16 and the collar 17 into the hole in the engine block. At this point, the two clamping plates 3 on the clamp 2 are activated, causing them to move closer together under the drive of a driving mechanism (such as a motor), while the stop lever 24 serves as a positioning and warning mechanism. As the clamping plates 3 move, the rubber auxiliary blocks 70 on their surfaces also press against the surface of the engine block, thus helping to stabilize the engine block and preventing swaying when lifting it later. Then, the servo motor 11 moves the movable block 13 and the fixed frame 14 upwards, thereby using the cooperation of the lifting column 16 and the collar 17 to lift the engine block.

[0026] When the electric push rod 15 lifts the engine block via the lifting column 16, the connecting frame 21 and the sliding plate 22 work together to provide auxiliary support for the lifting column 16. This prevents insufficient support due to relying solely on the output rod of the electric push rod 15, which could lead to damage to the output rod after prolonged and repeated use. When the movable block 13 moves, the support block 23 slides within the clamping plate 3, also providing auxiliary support and movement. The multi-stage telescopic plate 30 is designed to move in conjunction with the fixed frame 14 and simultaneously close the clamping plate 3, thereby reducing the entry of impurities into the clamping plate 3 and minimizing their impact on the coordinated movement of the lead screw 12 and the movable block 13.

[0027] The aforementioned design changes the traditional method of directly clamping and lifting the engine block. It utilizes the lifting column 16 and the collar 17 to lift the engine block through the opening, thus adapting to different types of engine blocks and ensuring a large contact area during lifting. The collar 17, made of rubber, acts as a buffer and protects the engine block, while the auxiliary block 70 ensures stability and prevents the engine block from easily wobbling during lifting. The flexible material design effectively prevents indentations, scratches, and impacts on the engine block surface caused by hard contact, thus avoiding damage to the engine block and subsequent repairs.

[0028] A spraying mechanism 40 is installed inside the clamping plate 3. The spraying mechanism 40 includes two rubber storage boxes 42 symmetrically arranged inside the clamping plate 3. One side of the storage box 42 is fixedly installed with an inlet pipe that communicates with the interior and has a one-way valve, and the other side of the storage box 42 is fixedly installed with an outlet pipe that communicates with the interior and has a one-way valve. Squeezing blocks 41 are provided on both sides of the support block 23. Several inclined spraying pipes 43 are fixedly installed at the bottom of the fixing frame 14, and the end of the outlet pipe away from the storage box 42 is connected to several spraying pipes 43.

[0029] Specifically, one end of the extrusion block 41 is arc-shaped, and several rolling columns 44 are rotatably connected to the arc-shaped surface of the extrusion block 41. The extrusion block 41 slides within the support block 23 via an elastic rope 47, and a first electromagnet 45 is fixedly installed within the support block 23, while a second electromagnet 46 is fixedly installed on one side of the extrusion block 41.

[0030] During operation, when the servo motor 11 moves the movable block 13 downward from its initial position, it first energizes the first electromagnet 45 and the second electromagnet 46 within the support block 23. This causes the pressing block 41, along with the first electromagnet 45 and the elastic rope 47, to move away from the support block 23, positioning the pressing block 41 above the elastic block 51. Subsequently, as the servo motor 11 moves the support block 23 downward, it utilizes the curved surface of the pressing block 41 and several rolling columns 44 to compress the deformable liquid reservoir 42. This allows the liquid (lubricating oil) within the reservoir 42 to flow through the outlet pipe into several spray pipes 43, spraying it onto the surface of the engine block to form a protective film. When the pressing block 41 is not in use, the first electromagnet 45 and the second electromagnet 46 are de-energized, and the pressing block 41 slides back to its original position under the action of the elastic rope 47, ready for subsequent use.

[0031] With the structure designed above, spraying lubricating oil before the engine block is clamped by the rubber auxiliary block 70 allows a thin and uniform lubricating barrier film to be quickly formed between the precision contact surface of the cylinder block and the rubber clamping surface. This effectively prevents scratches, indentations, or marks on the machined surface of the cylinder block caused by direct friction and compression during clamping, reduces friction and local stress at the contact points, minimizes microscopic damage to the cylinder block surface, and also helps to adsorb hard impurities such as fine dust and iron filings from the air or workpiece surface, preventing impurities from being trapped between the clamping plate and the cylinder block and causing secondary impact damage. This maximizes the protection of the cylinder block's surface precision and smoothness, while also improving the smoothness and stability of the rubber clamp 2, ensuring that the cylinder block is not damaged by clamping during transportation and processing.

[0032] A stirring mechanism 50 is provided inside the clamping plate 3. The stirring mechanism 50 includes a deformable and hollow elastic block 51. A connecting pipe 52 is fixedly installed inside the liquid storage box 42. A slide rod 53 is slidably connected inside the connecting pipe 52. A connecting plate 54 is fixedly installed at one end of the slide rod 53. A plurality of fan blades 55 are provided at one end of the connecting plate 54. The connecting pipe 52 and the elastic block 51 are connected by a conduit 56.

[0033] During operation, when the lubricating oil needs to be stirred after prolonged use, the servo motor 11 starts, moving the movable block 13 upwards before moving the support block 23 and the movable block 13 downwards, using the support block 23 to compress the elastic block 51. After being compressed, the gas inside the elastic block 51 enters the connecting pipe 52 through the conduit 56, thereby pushing the sliding rod 53 sealed inside the connecting pipe 52. The sliding rod 53 then moves through the connecting plate 54, carrying several fan blades 55, within the liquid storage box 42. As the fan blades 55 move, they come into contact with the liquid in the liquid storage box 42, causing them to rotate and thus agitate the liquid inside the liquid storage box 42. When the elastic block 51 is no longer compressed, the sliding rod 53, along with the connecting plate 54 and the fan blades 55, returns to its original position, and the gas returns to the elastic block 51 through the conduit 56.

[0034] The agitation mechanism 50 designed above allows the lubricating oil in the reservoir 42 to be periodically agitated and mixed. This is because engine-specific lubricating oil contains composite additives such as lubricants, film-forming agents, and rust inhibitors. Issues such as sedimentation of active ingredients, uneven concentration, and even oil-water separation can occur. Therefore, periodic agitation is necessary to ensure thorough and uniform mixing of all oil components, guaranteeing the formation of a stable and uniform protective film on the cylinder block surface after spraying. Simultaneously, it keeps fine iron filings, dust, and other impurities mixed in with the oil suspended, preventing sedimentation and clogging of the spray lines and nozzles. It also prevents localized oxidation and deterioration of the oil due to prolonged static storage, ensuring consistently stable lubrication, isolation, and protective performance of the lubricating oil, and guaranteeing reliable protection of the cylinder block's precision contact surfaces.

[0035] The multi-stage telescopic plate 30 is equipped with an air blowing mechanism 60, which includes an air inlet pipe 61 with a one-way valve and connected to the interior of the multi-stage telescopic plate 30. An air outlet pipe 62 with a one-way valve and connected to the interior is fixedly installed on the surface of the multi-stage telescopic plate 30. One end of the air outlet pipe 62 is connected to the interior of the spray pipe 43. The several hollow plates of the multi-stage telescopic plate 30 are sealed and slidably connected, and the several hollow plates are connected through through holes.

[0036] During operation, as the multi-stage telescopic plate 30 moves downwards following the fixed frame 14, it draws in external air through the air intake pipe 61 and fills the multi-stage telescopic plate 30 through several through holes. At this time, since the other multi-stage telescopic plate 30 is initially full of air, when it moves in coordination, the air will enter the injection pipe 43 through the air outlet pipe 62 and be blown towards the engine block, which serves to pre-clean the engine block and facilitate the subsequent spraying of lubricating oil.

[0037] After the multi-stage telescopic plate 30 moves with the fixed frame 14 and is filled with gas, as the fixed frame 14 moves upward, the gas-filled multi-stage telescopic plate 30 will blow the gas into the injection pipe 43 through the air outlet pipe 62, and then blow it towards the lubricating oil on the surface of the engine cylinder through the injection pipe 43.

[0038] With the above-described structure, the engine block is blew air before lubricating oil is sprayed. This pre-cleans the contact surface between the cylinder block and the rubber clamping plate, removing impurities such as iron filings and dust. This prevents impurities from scratching the precision contact surface of the cylinder block during clamping, providing a clean surface foundation for subsequent oil spraying. Blowing air after lubricating oil spraying ensures that the oil is evenly spread and forms a continuous, thin, and stable lubricating protective film in the contact area. At the same time, it removes excess liquid, ensuring the protective effect of the oil film without affecting the clamping friction and positioning stability of the rubber clamping plate.

[0039] Working principle: During the processing and transfer of the engine block, a robotic arm 1 is used. The robotic arm 1 moves the clamp 2 and clamping plates 3 to the engine block, positioning the two clamping plates 3 on either side of the engine block. At this point, the servo motor 11 within the clamping plates 3 is activated. The lead screw 12 of the servo motor 11 moves the movable block 13 and the fixed frame 14 up and down. As the fixed frame 14 moves, it also moves components such as the lifting column 16, the collar 17, and the sensor 18. The sensor 18 positions the lifting column 16 at the hole in the engine block, sending a signal to the controller to stop the servo motor 11, ensuring that the lifting column 16 and the collar 17 are aligned with the hole in the engine block. Then, the electric push rod 15 within the fixed frame 14 is activated, moving the lifting column 16 and the collar 17 into the hole in the engine block. At this point, the two clamping plates 3 on the clamp 2 are activated, moving closer together under the drive mechanism. The stop lever 24 serves as a positioning and warning mechanism. As the clamping plate 3 moves, the rubber auxiliary block 70 on its surface will also press tightly against the surface of the engine block, thereby helping to stabilize the engine block and preventing it from shaking when lifting the engine block later. At this time, the servo motor 11 moves the movable block 13 and the fixed frame 14 upward, thereby using the cooperation of the lifting column 16 and the collar 17 to lift the engine block.

[0040] When the electric push rod 15 lifts the engine block via the lifting column 16, the connecting frame 21 and the sliding plate 22 work together to provide auxiliary support for the lifting column 16. This prevents insufficient support due to relying solely on the output rod of the electric push rod 15, which could lead to damage to the output rod after prolonged and repeated use. When the movable block 13 moves, the support block 23 slides within the clamping plate 3, also providing auxiliary support and movement. The multi-stage telescopic plate 30 is designed to move in conjunction with the fixed frame 14 and simultaneously close the clamping plate 3, thereby reducing the entry of impurities into the clamping plate 3 and minimizing their impact on the coordinated movement of the lead screw 12 and the movable block 13.

[0041] When the servo motor 11 moves the movable block 13 downward from its initial position, it first energizes the first electromagnet 45 and the second electromagnet 46 inside the support block 23, causing the squeezing block 41, along with the first electromagnet 45 and the elastic rope 47, to move away from the support block 23, thus positioning the squeezing block 41 above the elastic block 51. Subsequently, as the servo motor 11 moves the support block 23 downward, it uses the arc-shaped surface of the squeezing block 41 and several rolling columns 44 to squeeze the deformable liquid reservoir 42, allowing the liquid inside the reservoir 42 to enter several spray pipes 43 through the outlet pipe, thereby spraying it onto the surface of the engine block to form a protective film. When the squeezing block 41 is not in use, the first electromagnet 45 and the second electromagnet 46 are de-energized, and the squeezing block 41 slides back to its original position under the action of the elastic rope 47 for subsequent use.

[0042] When the lubricating oil needs to be stirred after prolonged use, the servo motor 11 starts, and before moving the movable block 13 downwards, it first moves the support block 23 and the movable block 13 upwards, using the support block 23 to compress the elastic block 51. After being compressed, the gas inside the elastic block 51 enters the connecting pipe 52 through the conduit 56, thereby pushing the sliding rod 53 sealed inside the connecting pipe 52. The sliding rod 53 then moves through the connecting plate 54, carrying several fan blades 55, within the liquid storage box 42. As the fan blades 55 move, they come into contact with the liquid in the liquid storage box 42, causing them to rotate and thus agitate the liquid inside the liquid storage box 42. When the elastic block 51 is no longer compressed, the sliding rod 53, along with the connecting plate 54 and the fan blades 55, returns to its original position, and the gas returns to the elastic block 51 through the conduit 56.

[0043] As the multi-stage telescopic plate 30 moves downwards following the fixed frame 14, it draws in external gas through the intake pipe 61 and fills the multi-stage telescopic plate 30 with gas through several through holes. Meanwhile, another multi-stage telescopic plate 30, already fully inflated initially, releases gas through the exhaust pipe 62 into the injection pipe 43 during its movement, blowing it towards the engine block to pre-clean the block and facilitate subsequent lubricant spraying. After the multi-stage telescopic plate 30 moves with the fixed frame 14 and is filled with gas, as the fixed frame 14 moves upwards, the gas-filled multi-stage telescopic plate 30 blows gas through the exhaust pipe 62 into the injection pipe 43, which then blows the gas towards the lubricant on the engine block surface.
