Description

Technical Field

[0001] This invention relates to the field of cylinder liner processing equipment, and in particular to a cylinder liner surface texture treatment equipment. Background Technology

[0002] Cylinder liners are core components of internal combustion engines. The surface texture of the cylinder liner's inner wall directly affects lubrication, friction loss, and service life during operation. By machining oil-retaining micro-pits and continuous mesh textures on the inner wall of the cylinder liner, the oil-retaining capacity can be effectively improved, reducing friction and wear between the piston and cylinder liner, and ensuring the long-term stable operation of the internal combustion engine. In the cylinder liner manufacturing process, surface texture treatment is a key step in improving product performance. Internal combustion engines operating under different conditions have different requirements for the shape and arrangement of the cylinder liner's inner wall texture. Some conditions require discrete oil-retaining micro-pit structures, while others are suited to continuous mesh structures. Currently, conventional cylinder liner texture processing equipment can only achieve single-pattern texture processing and cannot adapt to diverse texture processing needs, resulting in limited equipment adaptability. Meanwhile, conventional equipment has insufficient stability in cylinder liner clamping and positioning, and the workpiece is prone to positional deviation during processing, which will cause problems such as poor uniformity of texture processing and low forming accuracy. Furthermore, the instability of equipment lifting processing and transmission coordination further affects the processing quality and consistency of cylinder liner surface texture, making it difficult to meet the needs of batch and high-standard cylinder liner production and processing. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing equipment in the prior art, such as limited texture processing patterns, weak workpiece clamping adaptability, and insufficient processing accuracy stability, and to propose a cylinder liner surface texture processing device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A cylinder liner surface texture treatment device includes a support base plate, four symmetrical support legs fixedly installed on the top of the support base plate, a common support top plate fixedly installed on the top of the four support legs, two symmetrically arranged T-shaped plates fixedly installed between the top of the support base plate and the bottom of the support top plate, and a fixed connecting plate. T-shaped holes are opened on both sides of the fixed connecting plate, the T-shaped holes and the T-shaped plates are slidably connected, and a clamping assembly for clamping the cylinder liner is provided on one side of the fixed connecting plate. Two guide sleeves are fixedly inserted inside the supporting top plate, and a guide rod II slides through the inside of the guide sleeve. The bottom of the two guide rods II is fixedly installed with the same strip-shaped base plate, and a processing component for processing the cylinder liner is provided at the bottom of the strip-shaped base plate. The top of the supporting top plate is equipped with a lifting assembly for raising and lowering the strip bottom plate.

[0005] In one possible design, the clamping assembly includes a guide rail fixedly mounted on one side of a fixed connecting plate, two symmetrically arranged sliders slidably connected to the outer wall of the guide rail, a mounting plate fixedly mounted on one side of the sliders, and a clamping plate fixedly mounted on one side of the mounting plate.

[0006] In one possible design, two symmetrically arranged fixing rods and two guide rods I are fixedly installed on the other side of the fixed connecting plate. One end of the two guide rods I and the two fixing rods is fixedly installed with the same fixed side plate. The fixed connecting plate and the fixed side plate are rotatably connected by the same lead screw. One end of the lead screw is fixedly installed with a handwheel. The outer wall of the two guide rods I is slidably fitted with the same threaded plate, and the thread of the lead screw passes through the threaded plate.

[0007] In one possible design, T-shaped blocks are fixedly installed on the top of the threaded plate and the top of the slider. Rotating shafts are rotatably connected to both sides of the top of the fixed connecting plate. V-shaped plates are fixedly fitted on the outer walls of the two rotating shafts. Two symmetrically arranged strip holes are opened inside the V-shaped plates. The two T-shaped blocks slide through the two strip holes respectively.

[0008] In one possible design, the processing assembly includes a servo motor fixedly mounted on the top of a strip base plate, the output shaft of the servo motor rotating through the strip base plate and fixedly mounted with a connecting shaft, and a supporting inner plate fixedly mounted at the bottom of the connecting shaft.

[0009] In one possible design, four upper screws are fixedly installed on the top of the inner support plate, and four lower screws are fixedly installed on the bottom of the inner support plate. The outer walls of the upper and lower screws are threaded with matching limiting nuts. A fixed circular plate is rotatably connected to the top center of the inner support plate via a bearing. An anti-rotation rod is fixedly connected to the top surface of the fixed circular plate. The top end of the anti-rotation rod slides through the strip-shaped bottom plate and is circumferentially limited. Multiple protrusions are arranged in a ring on the outer wall of the fixed circular plate. A limiting circular plate is fixedly installed at the bottom of the inner support plate, and a slanted groove is formed on the bottom outer wall of the limiting circular plate.

[0010] In one possible design, a mounting ring is also included, which has multiple circular holes inside. The mounting ring is used in conjunction with a lower screw and an upper screw. The mounting ring has a rectangular hole inside and a clearance groove on its inner wall. A cutting head slides through the rectangular hole. A compression spring is provided between one side of the cutting head and one side of the inner wall of the clearance groove.

[0011] In one possible design, the lifting assembly includes the same strip-shaped top plate fixedly installed on the top of the two guide rods II, an electric push rod fixedly installed on the top of the supporting top plate, the piston rod of the electric push rod being fixedly connected to the bottom of the strip-shaped top plate, and a dust discharge hole being provided at the middle position of the bottom of the supporting bottom plate.

[0012] In this application, when in use, the cylinder liner is placed on top of the support base plate. At this time, the handwheel can be turned, which drives the lead screw to rotate. The lead screw drives the threaded plate to move laterally. The threaded plate slides on the two guide rods I to ensure the stability of the threaded plate movement. When the threaded plate moves, it can drive the T-block to move laterally. The T-block drives the V-plate to rotate around the rotating shaft. The V-plate drives the T-block on the other side to move. The T-block drives the slider to slide on the surface of the guide rail. At this time, the slider drives the mounting plate to move laterally. The mounting plate drives the clamping plate to move laterally. At this time, the two clamping plates clamp the cylinder liner. During processing, the electric push rod can be activated. The piston rod of the electric push rod drives the strip top plate to move down, the strip top plate drives the guide rod II to move down, the guide rod II drives the strip bottom plate to move down, and in conjunction with the activation of the servo motor, the output shaft of the servo motor drives the connecting shaft to rotate, and the connecting shaft drives the inner support plate to rotate. At this time, the cutter head has two working modes. One mode is when the mounting ring is assembled to the upper screw and rotates synchronously with the inner support plate, the fixed circular plate remains stationary, and the protrusion can intermittently abut and push the cutter head to complete the radial extension and retraction action, stably processing discretely distributed oil storage micro-pits. If the mounting ring is installed on the lower screw, the inclined surface of the groove will abut against one end of the cutter head. At this time, the mounting ring can be limited by the limiting nut, and one end of the cutter head will abut against the outer wall of the limiting circular plate, ensuring that the cutter head is always in the extended state, physically engraving a continuous mesh pattern on the inner wall, making it more convenient to use.

[0013] Beneficial Effects: This equipment relies on a supporting base plate, supporting legs, and supporting top plate to form an integral load-bearing base. Combined with a sliding fit structure of T-shaped plates and fixed connecting plates, it provides a stable working foundation for workpiece clamping and texturing. The overall assembly structure is neat and the operation is highly stable, effectively ensuring the accurate execution of subsequent processing steps. The equipment is equipped with a dedicated clamping assembly. Through the linkage of lead screws, threaded plates, and V-shaped plates, it can drive the clamping plates on both sides to simultaneously complete the clamping and positioning operations. It can adapt to cylinder liner workpieces of different specifications and sizes. The clamping process is characterized by uniform force, effectively fixing the workpiece position and preventing workpiece displacement during processing, thus ensuring the overall accuracy and uniformity of the texturing process.

[0014] This equipment features an independent lifting assembly. Through an electric push rod paired with guide rod II and guide sleeve, it precisely controls the vertical lifting stroke of the strip base plate and the bottom processing assembly. The lifting process is smooth and undisturbed, accurately matching the processing position requirements of cylinder liners of different heights, ensuring the precision of the fit between the processing head and the inner wall of the workpiece, and improving the regularity of the weaving pattern. The processing assembly relies on a servo motor to provide rotational power, driving the supporting inner plate and the matching processing structure to rotate at a uniform speed. This provides stable rotational operating conditions for the inner wall weaving process, ensuring a uniform and regular weaving pattern.

[0015] This equipment can perform two different machining modes for the inner wall texture of cylinder liners. By switching the assembly position of the mounting ring on the upper and lower screws, discrete oil reservoir micro-pits and continuous mesh textures can be completed respectively. When the mounting ring is assembled on the upper screw, the protrusion on the outer side of the fixing plate can intermittently push the cutter head to extend and retract, and with the reset action of the compression spring, a uniformly distributed oil reservoir micro-pit is stably machined. When the mounting ring is assembled on the lower screw, the inclined groove of the limiting plate can keep the cutter head continuously extended, stably carving a continuous mesh structure. The two machining modes can be flexibly switched to meet the machining needs of cylinder liners under different working conditions, greatly improving the applicability of the equipment.

[0016] The equipment features a tightly integrated transmission and processing structure with strong interoperability among its components. This allows for stable and standardized texturing of the cylinder liner inner wall, resulting in consistent processing quality. It is well-suited for large-scale, standardized cylinder liner production, effectively improving the processing quality and performance of cylinder liner products. Furthermore, the dust removal holes at the bottom of the support base plate ensure timely removal of debris and dust generated during processing, maintaining a clean working environment and guaranteeing long-term stable operation of the equipment.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] In one embodiment: Refer to Figure 1-6 This embodiment discloses a processing device. The device relies on a supporting base plate 1 as its bottom load-bearing base. Four symmetrical supporting legs 2 are fixedly mounted on the top of the supporting base plate 1. The tops of the four supporting legs 2 are jointly fixedly connected to a supporting top plate 5, thus forming a vertical load-bearing frame structure for the entire device, which can provide stable load-bearing support for the upper processing structure. Further, two symmetrically arranged T-shaped plates 3 are fixedly installed between the supporting base plate 1 and the supporting top plate 5. T-shaped holes 20 matching the shape of the T-shaped plates 3 are opened on both sides of the fixed connecting plate 9. The fixed connecting plate 9 slides with the T-shaped plates 3 through the T-shaped holes 20, allowing the fixed connecting plate 9 to slide smoothly along the length of the T-shaped plates 3. This allows for fine-tuning of the overall position of the clamping structure according to the actual specifications of the cylinder liner workpiece, adapting to the clamping requirements of workpieces of different sizes. Specifically, a clamping assembly is mounted on the outer side of the fixed connecting plate 9 to achieve stable clamping and positioning of the cylinder liner workpiece, ensuring that the workpiece position remains constant during subsequent texturing processing.

[0021] Furthermore, the clamping assembly includes a guide rail 10 fixedly mounted on one side of the fixed connecting plate 9. Two symmetrically arranged sliders 22 are slidably mounted on the outer side of the guide rail 10. The sliders 22 can slide laterally linearly along the guide rail 10. A mounting plate 11 is fixedly mounted on the outer side of each slider 22. A clamping plate 12 is fixedly mounted on the outer side of the mounting plate 11. The relative movement of the clamping plates 12 on both sides can realize the clamping and releasing operation of the cylinder liner workpiece. On this basis, two symmetrically arranged fixing rods 7 and two guide rods I 14 are fixedly mounted on the other side of the fixed connecting plate 9. The ends of the fixing rods 7 and the guide rods I 14 are jointly fixedly connected to the fixed side plate 8, so that a stable connection frame structure is formed between the fixed side plate 8 and the fixed connecting plate 9. Specifically, a lead screw 16 is rotatably mounted between the fixed connecting plate 9 and the fixed side plate 8. One end of the lead screw 16 passes through the fixed side plate 8 and is fixedly mounted with a handwheel 15. When the operator rotates the handwheel 15, the lead screw 16 can be driven to rotate continuously. The outer walls of the two guide rods I 14 are slidably fitted with threaded plates 18. The lead screw 16 and the threaded plates 18 form a threaded transmission engagement. During the rotation of the lead screw 16, the threaded plates 18 can be driven to move smoothly laterally along the axial direction of the guide rods I 14. The guide rods I 14 can effectively limit the rotational freedom of the threaded plates 18, avoid transmission offset problems, and ensure the smoothness of the movement of the threaded plates 18.

[0022] Furthermore, T-blocks 19 are fixedly mounted on the top of the threaded plate 18 and the top of the slider 22. Rotating shafts 13 are rotatably mounted on both sides of the top of the fixed connecting plate 9. A V-shaped plate 21 is fixedly sleeved on the outer side of each rotating shaft 13. Two symmetrically arranged strip holes 17 are opened inside the V-shaped plate 21. The two sets of T-blocks 19 slide through the corresponding strip holes 17 to form a linkage transmission structure. Based on this, during the lateral movement of the threaded plate 18, the corresponding T-blocks 19 will push the V-shaped plate 21 to deflect around the rotating shaft 13. During the deflection of the V-shaped plate 21, it will cooperate with the T-blocks 19 through the strip holes 17 on the other side, pulling the slider 22 to slide synchronously along the guide rail 10. When the two sliders 22 on both sides come closer together, they can drive the two sets of clamping plates 12 to move synchronously, completing the centering and clamping positioning of the cylinder liner workpiece. The overall linkage transmission structure can ensure that the clamping force on both sides is uniform, effectively avoiding the workpiece's unilateral displacement and improving the clamping stability.

[0023] Two guide sleeves 25 are fixedly installed inside the supporting top plate 5. Each guide sleeve 25 has a guide rod II 26 that slides vertically through it. The bottom ends of the two guide rods II 26 are fixedly connected to the strip base plate 4. The precise cooperation between the guide sleeves 25 and the guide rods II 26 can limit the movement trajectory of the strip base plate 4, ensuring that the strip base plate 4 can only move vertically up and down, and preventing horizontal deviation during the processing. Furthermore, a lifting assembly is provided on the top of the supporting top plate 5 to drive the strip bottom plate 4 to complete the lifting and feeding action. The lifting assembly includes a strip top plate 27 fixedly mounted on the top of the two guide rods II 26. An electric push rod 28 is fixedly installed on the top surface of the supporting top plate 5. The bottom end of the piston rod of the electric push rod 28 is fixedly connected to the bottom surface of the strip top plate 27. When the electric push rod 28 is extended or retracted, it can drive the strip top plate 27 to move vertically, and synchronously drive the guide rods II 26 and the strip bottom plate 4 to rise and fall as a whole, thereby accurately adjusting the vertical processing height of the bottom processing assembly to adapt to the processing needs of cylinder liner workpieces of different height specifications.

[0024] The bottom of the strip-shaped base plate 4 is equipped with a machining assembly for machining the inner wall of the cylinder liner. Specifically, the machining assembly includes a servo motor 29 fixedly mounted on the top of the strip-shaped base plate 4. Preferably, the servo motor 29 is a high-precision speed-regulating motor, which can stably control the rotation speed and is suitable for fine texture machining conditions. The output shaft of the servo motor 29 vertically passes through the strip-shaped base plate 4 and is fixedly connected to the connecting shaft 24. The bottom end of the connecting shaft 24 is fixedly equipped with a supporting inner plate 37. After the servo motor 29 is started, it can drive the supporting inner plate 37 to rotate at a uniform speed through the connecting shaft 24, providing continuous and stable rotational power for the inner wall texture machining. Furthermore, four upper screws 31 are fixedly mounted on the top surface of the supporting inner plate 37, and four lower screws 36 are fixedly mounted on the bottom surface of the supporting inner plate 37. Limit nuts 32 are threaded on the outer side of both the upper screws 31 and the lower screws 36, which can realize the locking and positioning of the assembly structure. A fixed circular plate 30 is rotatably connected to the top center of the supporting inner plate 37 via a bearing. An anti-rotation rod is fixedly connected to the top surface of the fixed circular plate 30. The top end of the anti-rotation rod slides through the strip-shaped bottom plate 4 and is circumferentially limited. Multiple protrusions 35 are arranged in a ring on the outer wall of the fixed circular plate 30. A limiting circular plate 33 is fixedly mounted on the bottom surface of the supporting inner plate 37. A ring-shaped inclined groove 34 is opened on the bottom outer wall of the limiting circular plate 33, which can be used with the cutter head 38 to complete different modes of weaving processing operations. The mounting ring 23 can be selectively fitted and mounted on the outside of the upper screw 31 or the lower screw 36 and locked with the limiting nut 32 to realize the switching installation of the upper and lower work positions and match different weaving processing modes.

[0025] Based on this, the equipment is also equipped with a mounting ring 23. Multiple circular holes 40 are formed inside the mounting ring 23. These holes 40 can match the outer diameter of the upper screw 31 and the lower screw 36, allowing for switching between the upper and lower positions of the mounting ring 23. A rectangular hole 41 is also formed inside the mounting ring 23, and a clearance groove 42 is formed on the inner wall of the rectangular hole 41. Specifically, a cutter head 38 is slidably mounted inside the rectangular hole 41. A compression spring 39 is fixedly connected between one end face of the cutter head 38 and the inner wall of the clearance groove 42. The compression spring 39 can always provide an elastic restoring force to the cutter head 38, ensuring the flexibility and stability of the cutter head 38's extension and retraction. An auxiliary limiting structure is provided inside the clearance groove 42, which works with the compression spring 39 to limit the extension and retraction stroke of the cutter head 38, preventing the cutter head 38 from shifting or jamming, and ensuring the stability and restoring accuracy of the cutter head's extension and retraction.

[0026] During actual operation, the cylinder liner to be processed is placed stably on the top surface of the support base plate 1. The handwheel 15 is manually turned to drive the lead screw 16 to rotate. The lead screw 16 drives the threaded plate 18 to slide laterally along the guide rod I 14. The threaded plate 18 pushes the V-shaped plate 21 to deflect through the top T-block 19, which in turn causes the sliders 22 on both sides to move relative to the clamping plate 12, thus completing the centering and clamping of the cylinder liner. Then, the electric push rod 28 is started. The piston rod of the electric push rod 28 retracts or extends, driving the strip top plate 27 and the guide rod II 26 to move vertically, so that the strip base plate 4 and the bottom processing structure are lowered to a suitable processing height inside the cylinder liner. The servo motor 29 is started to drive the support inner plate 37 to rotate at a uniform speed, and the weaving processing operation can then be carried out.

[0027] The equipment has two switchable texture processing modes. When the mounting ring 23 is assembled to the upper screw 31 and rotates synchronously with the inner support plate 37, the fixed circular plate 30 remains stationary, and the protrusion 35 can intermittently abut and push the cutter head 38 to complete the radial extension and retraction action, stably processing discretely distributed oil storage micro-pits. Unlike the above embodiments, after the mounting ring 23 is disassembled, it is assembled to the outside of the lower screw 36 and locked in place. The inclined groove 34 on the outer wall of the limiting circular plate 33 will continuously abut against the end of the cutter head 38, limiting the retraction displacement of the cutter head 38 and keeping the cutter head 38 in a constant extended state. During rotation, the cutter head 38 can continuously engrave patterns on the inner wall of the cylinder liner to form a regular continuous mesh texture. The two processing modes can be freely switched according to actual production needs, effectively improving the processing adaptability range of the equipment. The sliding transmission areas of the lead screw 16, guide rail 10, T-plate 3, guide rod I 14 and guide rod II 26 are all equipped with dustproof protection structures to prevent processing dust and debris from entering the mating gap. During the use of the equipment, the sliding transmission parts can be cleaned and lubricated regularly to ensure the smooth operation of each sliding and transmission structure for a long time. During long-term continuous processing, the thread transmission parts and sliding guide parts can be cleaned and lubricated regularly to effectively extend the service life of the equipment and continuously ensure processing accuracy.

[0028] This application can be used in the field of cylinder liner processing equipment, or in other fields applicable to this application.

[0029] In another embodiment: Reference Figure 1-6 A cylinder liner surface texturing treatment device is used in the field of cylinder liner processing equipment. The structure of this embodiment is basically the same as that of the aforementioned embodiment. The difference is that a dust discharge hole 6 is provided at the bottom center of the support base plate 1. Metal chips and dust generated during the texturing process can be discharged out in time through the dust discharge hole 6 to avoid chips accumulating inside the equipment and affecting the transmission accuracy of the structure, and to continuously ensure the stability and processing accuracy of the equipment in the long term.

[0030] The equipment is equipped with a controller on the outside. The controller is electrically connected to the electric push rod 28 and the servo motor 29. The controller can uniformly control the extension and retraction stroke and start / stop status of the electric push rod 28, and at the same time control the rotation speed and working time of the servo motor 29, so as to realize the coordinated operation of the equipment lifting and feeding and rotation processing.

[0031] However, as is well known to those skilled in the art, the working principles and wiring methods of the controller, electric actuator 28, and servo motor 29 are all conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0032] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
