Description

Technical Field

[0001] The invention relates to the technical field of cylinder liner honing, and in particular to a cylinder liner production and processing honing machine. Background Art

[0002] Cylinder liner production and processing honing machine is a kind of equipment specially used for finishing the inner surface of cylinder liner. It achieves high-precision inner hole processing effect by reciprocating and rotating cutting in the cylinder liner through the honing head equipped with honing stone. This equipment can effectively remove the tiny unevenness of the inner surface of the cylinder liner, improve the surface finish and dimensional accuracy, and extend the service life of the cylinder liner. Honing machine is usually equipped with automatic control system to ensure stable and reliable processing process, and is an indispensable tool in engine manufacturing and maintenance.

[0003] In the prior art, when honing a cylinder liner, the honing process is generally divided into three stages: rough honing, medium honing and fine honing. Each stage uses honing stones of different particle sizes, and the particle size of the honing stones decreases step by step. When replacing the honing stone of the honing head, it is necessary to loosen the fixing structure of the honing stone, remove the old honing stone, re-insert the honing stone of the new particle size at the installation position of the honing head, and re-tighten the fixing structure of the honing stone, resulting in a long downtime of the entire honing machine. Frequent disassembly and assembly may cause increased wear of the mechanical parts of the equipment (such as clamps, screws, and fixing devices), increasing the maintenance and servicing requirements of the equipment.

The outer wall of the mounting rollers is installed with honing stones of different particle sizes. A switching assembly is set between the mounting rollers in the circular array.

The expansion assembly can temporarily drive the installation rollers of the circular array away from the inner wall of the cylinder liner when the switching assembly is actuated to avoid the honing stones of the outer wall array of the installation rollers from colliding with the inner wall of the cylinder liner during switching. The switching assembly of the present invention has a certain "elasticity". When the expansion assembly drives the installation rollers of the circular array to move away from or closer to each other, the switching assembly always ensures that the rotation of multiple installation rollers remains synchronized, so that the honing stones of different grain sizes on the multiple installation rollers can be moved to the honing position synchronously.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] Reference Figure 1-13 A cylinder liner production and processing honing machine comprises a vertical frame 1, a vertical shift seat 13 and a horizontal seat 12. The top of the vertical frame 1 is rotatably connected to the top of a switching screw rod 5. A threaded barrel 16 is screwed into the outer wall of the switching screw rod 5. The threaded barrel 16 is vertically fixed on the vertical shift seat 13. A vertical plate 11 is fixedly provided at the bottom of the side of the vertical frame 1 by bolts. A horizontal seat 12 is fixedly provided on the side of the vertical plate 11. The bottom of the switching screw rod 5 is rotatably connected to the top of the horizontal seat 12. A driving motor 7 is fixedly provided on the top of the vertical shift seat 13. A driving shaft 8 is fixedly provided at the output end of the driving motor 7. An avoidance hole is opened in the vertical direction of the horizontal seat 12. The driving shaft 8 passes through the avoidance hole at the corresponding position of the horizontal seat 12.

[0037] A controller 2 is fixedly installed on the front side of the vertical frame 1, and vertical blocks 14 are symmetrically fixedly installed on both sides of the vertical shift seat 13. The vertical blocks 14 are movably inserted with vertical guide rails 6 along the vertical direction. The vertical guide rails 6 are fixedly installed on the side of the vertical frame 1 along the vertical direction. The side of the vertical block 14 is fixedly welded to the side of the triangular plate 15, and the other end of the triangular plate 15 is fixedly welded to the side of the vertical shift seat 13. The triangular plate 15 improves the connection strength between the vertical block 14 and the vertical shift seat 13.

[0038] The vertical guide rail 6 and the vertical shift block 14 are common guide parts in the prior art. The vertical guide rail 6 and the vertical shift block 14 assist the vertical shift seat 13 to move in the vertical direction in cooperation with the switching screw 5 and the threaded tube 16. A honing assembly for honing the cylinder liner is provided at the end of the driving shaft 8. The vertical shift seat 13 drives the honing assembly at the end of the driving shaft 8 to reciprocate in the vertical direction. It should be supplemented that the controller 2 can control the rotation angle of the reciprocating motor 4, thereby controlling the reciprocating stroke of the vertical shift seat 13 on the switching screw 5 in the vertical direction according to the actual vertical height of the inner wall of the cylinder liner to be honed, and perform part of the honing process.

[0039] The honing assembly includes a mounting triangular seat 17, a center column 22, an expansion triangular seat 21, a honing stone 42, a mounting roller 38, and an intermediate column 39. The expansion triangular seat 21 is fixedly arranged in the middle position of the side of the center column 22, and a switching assembly for switching honing stones 42 of different grain sizes is arranged in the middle position of the center column 22.

[0040] The expansion triangular seat 21 is provided with an expansion component for driving multiple groups of mounting rollers 38 to approach each other and thus drive the honing stone 42 to fit the inner wall of the cylinder sleeve. The mounting triangular seats 17 are fixedly provided at both ends of the center column 22. The mounting triangular seat 17 has a circular array of transverse displacement grooves 19. A guide column 20 is fixedly provided on the side of the transverse displacement groove 19. An edge block 18 is movably inserted into the outer wall of the guide column 20. The circular array of the outer wall of the mounting roller 38 has three groups of honing stones 42. The side of the honing stone 42 away from one end of the mounting roller 38 is arranged to be an arc surface. The particle sizes of the three groups of honing stones 42 increase successively. The mounting roller 38 is fixedly provided with a holding plate 41 at both ends. The holding plate 41 at one end of the mounting roller 38 is rotatably connected to the side of the edge block 18. The guide column 20 assists the edge block 18 to move transversely in a specific direction.

[0041] The grits of the three groups of honing stones 42 increase in sequence. The grits of the three groups of honing stones 42 are selected from coarse, medium and fine. First, a coarse-grained honing stone 42, specifically one hundred to two hundred, is used to remove larger flaws on the inner wall of the cylinder liner. Then, a medium-grained honing stone 42, specifically four hundred to six hundred, is used to further smooth the inner wall surface of the cylinder liner. Finally, a fine-grained honing stone 42, specifically one thousand to two thousand, is used to finely polish the inner wall of the cylinder liner to achieve higher smoothness and glossiness.

[0042] A pressure holding plate 41 is fixedly provided at both ends of the middle column 39, and a mounting roller 38 is fixedly provided at one end of the pressure holding plate 41 away from the middle column 39. The diameter of the middle column 39 is much smaller than the diameter of the mounting roller 38. There are three groups of mounting rollers 38, totaling six mounting rollers 38, and two mounting rollers 38 form a group. The pressure holding plate 41 is fixed to both ends of the middle column 39 by multiple groups of bolts. There are mounting holes in a circular array on the side wall of the middle column 39. The pressure holding plate 41 is used to tightly fix the honing stone 42 on the mounting roller 38. The contact surface between the pressure holding plate 41 and the mounting roller 38 and both ends of the honing stone 42 are set to be frosted surfaces, so that the pressure holding plate 41 and the mounting roller 38 can cooperate to tightly fix the honing stone 42 on the mounting roller 38.

[0043] The switching assembly includes a driven gear 27, a driving gear rod 28, a transverse bolt 30, a double-sided synchronous belt 26, a holding pulley 261, and a switching pulley 40. The top circular array of the expanded triangular seat 21 has an intermediate groove 37, and a holding column 35 is fixedly arranged on the side of the intermediate groove 37. The outer wall of the holding column 35 is slidably connected to a holding block 36. The side of the holding block 36 is fixedly connected to one end of a holding spring 34, and the other end of the holding spring 34 is fixedly connected to the side of the intermediate groove 37. The top of the holding block 36 is rotatably connected to the holding pulley 261.

[0044] A driven gear 27 is coaxially fixed on the top of one set of pressure pulleys 261, and a driving gear rod 28 is stably meshed on the side of the driven gear 27. A guide rod 29 is movably inserted into the side of the driving gear rod 28. The other end of the guide rod 29 is fixedly connected to the side of the vertical block 31. The bottom of the vertical block 31 is fixedly connected to the top of the expansion triangle seat 21, and a transverse bolt 30 is rotatably connected to the bottom of the side of the driving gear rod 28.

[0045] The thread at the end of the transverse bolt 30 is screwed into the side of the vertical block 31. The head of the transverse bolt 30 is set as an inner hexagonal groove. The worker can use the inner hexagonal handle to rotate the transverse bolt 30. The transverse bolt 30 drives the driven gear 27 to rotate through the driving gear rod 28. The outer walls of the three sets of switching pulleys 40 are commonly sleeved with a double-sided synchronous belt 26. The double-sided synchronous belt 26 also passes through and meshes with the teeth of the holding pulley 261. The holding pulley 261 ensures that the double-sided synchronous belt 26 always remains in a taut state when the expansion component drives the three sets of mounting rollers 38 to move away from or approach each other.

[0046] The expansion component includes an inverted cone 33, an expansion column 25, an expansion spring 23, a transverse block 24, and a guide folding plate 210. The circular array on the top of the expansion triangle seat 21 is provided with a guide folding plate 210, and an expansion groove 2100 is opened on the top of the guide folding plate 210. The expansion column 25 is movably inserted into the side of the expansion groove 2100. The outer wall of the expansion column 25 is fixedly connected to one end of the expansion spring 23, and the other end of the expansion spring 23 is fixedly connected to the side of the expansion groove 2100. The other end of the expansion column 25 is fixedly connected to the transverse block 24, and the transverse block 24 is the same width as the expansion groove 2100.

[0047] The outer wall of the inverted cone 33 is screwed into the outer wall of the center column 22, and a section of external thread is set at the corresponding position on the outer wall of the center column 22. A rotating nut 32 is fixedly set on the top of the outer wall of the inverted cone 33, and the middle column 39 is movably inserted into the lateral block 24 along the vertical direction. The inverted cone 33 is a wide upper and narrow lower structure, and the expansion support column 25 is set to be hemispherical at one end away from the lateral block 24. The expansion support column 25 is fitted to the outer wall of the inverted cone 33 at one end away from the lateral block 24. When a worker uses a wrench to turn the rotating nut 32, The inverted cone cylinder 33 is driven to move downward along the outer wall of the center column 22. Since the outer wall of the inverted cone cylinder 33 is a structure that is wide at the top and narrow at the bottom, the inverted cone cylinder 33 can push the three groups of expansion columns 25 away from each other, thereby driving the installation rollers 38 at the ends of the three groups of expansion columns 25 to move away from or closer to each other. The honing stone 42 on the installation roller 38 can hone cylinder liners with different inner diameters within a certain range. The range depends on the length of the external thread set at the corresponding position on the outer wall of the center column 22 and the height of the inverted cone cylinder 33 in the vertical direction.

[0048] When the expansion spring 23 is at its original length, it is ensured that one end of the expansion column 25 which is set to be hemispherical is always in contact with the outer wall of the inverted cone cylinder 33. The outer wall of the inverted cone cylinder 33 is surface treated, such as heat treatment or hardening treatment, to improve the hardness and wear resistance of the material, or a wear-resistant coating or a hard plating layer can be applied to the surface of the outer wall to further improve its wear resistance and reduce the wear of the outer wall of the inverted cone cylinder 33 when it contacts with the expansion column 25.

[0049] A support rod 10 is vertically fixedly arranged at one end of the bottom of the horizontal seat 12 away from the vertical plate 11. The bottom of the support rod 10 is fixedly arranged on the side of the processing box 3. A three-jaw chuck 9 is arranged in the middle position of the inner cavity of the processing box 3. The three-jaw chuck 9 is a cylinder fixing device commonly used in the prior art. The three-jaw chuck 9 needs to be on the same axis as the axis of the drive shaft 8 during installation. A reciprocating motor 4 is vertically fixedly arranged on the top of the vertical frame 1. The reciprocating motor 4 is vertically fixedly arranged on the top of the vertical frame 1, and the output end of the reciprocating motor 4 is fixedly connected to the top of the switching screw 5.

[0050] It should be added that when the controller 2 controls the action of the reciprocating motor 4 and the drive motor 7, the drive motor 7 always keeps rotating, while the reciprocating motor 4 intermittently rotates forward and reverse, controlling the vertical displacement seat 13 on the switching screw 5 to move back and forth in the vertical direction, thereby driving the honing assembly to perform reciprocating movement in the vertical direction and unidirectional rotational motion, forming the so-called "honing" action.

[0051] The specific implementation steps and principles of the present invention are as follows:

[0052] In the initial state, the entire honing assembly is located directly above the processing box 3. When the honing assembly of the honing machine needs to switch the honing grain size, the worker uses a wrench to rotate the inverted cone 33 upward by rotating the nut 32. At this time, the ends of the multiple groups of expansion support columns 25 are no longer supported by the inverted cone 33, and the expansion support spring 23 resets to drive the lateral movement block 24 to move horizontally, thereby driving the installation rollers 38 of the outer wall array of the center column 22 to approach each other. The worker uses an inner hexagon wrench to rotate the lateral movement bolt 30, and the lateral movement bolt 30 drives the driving gear rod 28 to move horizontally, and the driving gear rod 28 drives the driven gear 27 through the driven gear 27 A holding pulley 261 rotates, and the holding pulley 261 drives the remaining two holding pulleys 261 to rotate through the double-sided synchronous belt 26, which drives the three switching pulleys 40 to rotate, and the switching pulley 40 drives the honing stones 42 of appropriate granularity on the outer walls of multiple installation rollers 38 to rotate to appropriate positions. Finally, the worker uses the wrench again to rotate the inverted cone cylinder 33 downward by rotating the nut 32. At this time, the ends of multiple groups of expansion support columns 25 are supported by the inverted cone cylinder 33, and the expansion support spring 23 resets to drive the transverse block 24 to move transversely, thereby driving the installation rollers 38 of the outer wall array of the center column 22 to approach each other.

[0053] The three-jaw chuck 9 at the bottom of the processing box 3 is inserted into the cylinder liner to be processed. After the cylinder liner is fixed with the three-jaw chuck 9, the worker starts the controller 2 to control the drive motor 7 to rotate. At the same time, the reciprocating motor 4 rotates reciprocatingly intermittently, and the switching screw 5 drives the vertical displacement seat 13 to move in the vertical direction intermittently. The drive motor 7 drives multiple sets of mounting rollers 38 through the drive shaft 8 to extend into the interior of the cylinder liner to hone the inner wall of the cylinder liner.

[0054] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
