AI Technical Summary
Traditional cylinder liner testing clamps cannot adapt to cylinder liners with different inner and outer diameters, resulting in long testing preparation time, low accuracy, uneven equipment accuracy, cumbersome adjustment process, and uneven clamping force distribution, which affects the accuracy of test data.
The system employs an internal clamping assembly. Through this assembly, multiple moving columns move synchronously outward along the moving groove, thereby driving the inner hard plate and the arc-shaped elastic plate to clamp the cylinder liner inspection component. This internal clamping assembly also drives multiple moving columns to move synchronously outward along the moving groove, achieving uniform tension force between the inner hard plate and the arc-shaped elastic plate on the cylinder liner's inner wall. This structure can adapt to cylinder liners of different inner diameters without requiring component replacement, improving inspection efficiency and accuracy.
It enables rapid adaptation to cylinder liners with different inner diameters, reduces test preparation time, and improves test efficiency and accuracy. The external clamping component is detachable to meet diverse test needs, reduce equipment investment costs, and ensures uniform clamping force to prevent cylinder liner misalignment and protect the cylinder liner from damage.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of parts processing technology, specifically a clamping component for cylinder liner inspection. Background Technology
[0002] In the field of engine manufacturing and repair, the cylinder liner, as a core component of the cylinder, directly affects the engine's power performance, fuel economy, and service life due to the smoothness, roundness, cylindricity of its inner wall, and the dimensional accuracy of its outer wall. Therefore, comprehensive quality control operations, such as dimensional measurement and defect detection, are required during cylinder liner production, repair, and inspection. During the inspection process, to ensure the accuracy of the test data, the cylinder liner must be stably fixed using clamping devices.
[0003] Traditional clamping components are mostly designed with fixed dimensions, which can only fit cylinder liners of a single specification. When dealing with cylinder liners with different inner and outer diameters, it is necessary to frequently change the clamping components, which not only increases the test preparation time and reduces the test efficiency, but may also affect the clamping accuracy due to installation errors during component replacement. Although some adjustable clamping components can achieve size adaptation, the adjustment process is cumbersome, and the clamping force distribution after adjustment is uneven, which can easily cause slight displacement of the cylinder liner during the test, affecting the accuracy of the test data. Utility Model Content
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art; to this end, the present invention proposes a clamping component for cylinder liner inspection.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a clamping component for cylinder liner inspection, comprising: Internal clamping assembly, the internal clamping assembly comprising: The positioning plate has multiple moving grooves evenly arranged along the axial direction on its surface. The movable column slides within the movable groove, and each top is fixed with an inner rigid plate; An arc-shaped elastic plate is fixed to the outer side of the inner rigid plate; Multiple movable columns move outward along the movable groove, thereby achieving the axial tensioning and clamping of multiple inner hard plates and arc-shaped elastic plates within the cylinder liner.
[0006] Preferably, the inner rigid plate slides on the surface of the positioning disk.
[0007] Preferably, the inner clamping assembly further includes: The limiting cylinder is fixed to the middle of the positioning plate surface and has a sliding push column inside; The sliding groove has multiple axially distributed on the limiting cylinder and each of them is slidably connected to a sliding column inside. The connecting block is hinged at one end to the sliding column and at the other end to the inner side of the inner hard plate.
[0008] Preferably, the other end of the sliding column is fixed to the surface of the pushing column, the pushing column slides up and down in the middle of the positioning plate, and the number of sliding grooves is the same as the number of moving grooves.
[0009] Preferably, an outer clamping assembly is detachably connected to the inner clamping assembly, and the outer clamping assembly is used to clamp the outer side of the cylinder liner.
[0010] Preferably, the external clamping assembly includes: The docking block slides at one end of the L-shaped right-angle groove and is slidably connected to a limit block on one side. The guide post is fixedly installed in the guide groove opened inside the docking block and has a guide plate with one end fixedly connected to the limiting block. A spring is fixed between the guide plate and the mating block and sleeved on the surface of the guide post; The outer clamping block is fixed to the top of the mating block.
[0011] Preferably, the limiting block slides at the other end of the L-shaped right-angle groove.
[0012] Preferably, the bottom of the positioning disk is fixedly connected to the chassis via multiple connecting columns, a cylinder is fixedly connected to one side of the chassis, and the output end of the cylinder is fixedly connected to an output shaft that slides in the middle of the chassis and is fixedly connected to one end of the push column.
[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model can drive multiple moving columns to move outward synchronously along the moving groove through the internal clamping component, thereby driving the inner hard plate and the arc-shaped elastic plate to form a uniform tension force on the inner wall of the cylinder liner. This structure can be adapted to cylinder liners with different inner diameter specifications without replacing the components, effectively reducing the test preparation time and improving the test efficiency. At the same time, multiple arc-shaped elastic plates are evenly distributed along the circumference of the inner wall of the cylinder liner, and the clamping force is evenly distributed, avoiding the cylinder liner from shifting due to uneven force, and ensuring the accuracy of the test data. (2) The external clamping component of this utility model is detachably connected to the internal clamping component through an L-shaped right-angle groove. When the detection scenario requires simultaneous fixation of the inner and outer sides of the cylinder liner, the external clamping component can be quickly assembled to form a bidirectional clamping positioning. When bidirectional clamping is not required, the external clamping component can be easily disassembled to retain the internal clamping function, thus meeting the diverse needs of different detection scenarios, greatly improving the versatility of the clamping component, and reducing the equipment investment cost. (3) In this utility model, the elastic counter-force of the spring in the outer clamping assembly provides clamping force for the outer clamping block. This clamping force has a certain buffering capacity, which can prevent the outer clamping block from causing rigid extrusion damage to the outer wall of the cylinder liner. At the same time, multiple outer clamping blocks are evenly distributed along the circumference of the outer wall of the cylinder liner, and cooperate with the inner tensioning force to form a two-way positioning inside and outside, which further improves the stability of the cylinder liner during the testing process and effectively eliminates the risk of displacement that may exist in a single clamping method.

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0017] Example 1 Please see Figure 1 - Figure 4 This application provides a clamping member for cylinder liner inspection, comprising: Internal clamping component 5, the internal clamping component 5 includes: The positioning disk 50 has multiple moving grooves 51 evenly arranged on its surface along the axial direction. The movable column 52 slides within the movable groove 51 and each top is fixedly connected to an inner rigid plate 53. The arc-shaped elastic plate 54 is fixed to the outer side of the inner rigid plate 53; Multiple movable columns 52 move outward along the movable groove 51 to achieve the axial tensioning and clamping of multiple inner hard plates 53 and arc-shaped elastic plates 54 inside the cylinder liner.
[0018] It should be noted that the arc-shaped elastic plate 54 is made of elastic material and can protect the inner shaft of the cylinder liner, preventing damage caused by excessive force.
[0019] In this embodiment, preferably, the inner hard plate 53 slides on the surface of the positioning disk 50.
[0020] In this embodiment, preferably, the inner clamping component 5 further includes: The limiting cylinder 55 is fixed to the middle of the surface of the positioning disk 50 and has a push column 56 slidably connected inside; The sliding groove 57 has multiple axially distributed on the limiting cylinder 55 and each of them is slidably connected to a sliding column 58. The connecting block 59 is hinged at one end to the sliding column 58 and at the other end to the inner side of the inner hard plate 53.
[0021] In this embodiment, preferably, the other end of the sliding column 58 is fixed to the surface of the pushing column 56, and the pushing column 56 slides up and down in the middle of the positioning disk 50. The number of sliding grooves 57 is the same as the number of moving grooves 51.
[0022] In this embodiment, preferably, the bottom of the positioning disk 50 is fixedly connected to the chassis 1 by multiple connecting columns 2, a cylinder 3 is fixedly connected to one side of the chassis 1, and the output end of the cylinder 3 is fixedly connected to an output shaft 4 that slides in the middle of the chassis 1 and is fixedly connected to one end of the push column 56.
[0023] It should be noted that one end of cylinder 3 is connected to a compressor (not shown) via an air pipe to achieve the extension and retraction of cylinder 3.
[0024] During implementation, when it is necessary to fix the inner shaft of the cylinder liner, multiple inner hard plates 53 and arc-shaped elastic plates 54 extend into the cylinder liner, and a cylinder 3 is set up. The output end of the cylinder 3, along with the output shaft 4 and the push column 56, moves downward along the middle of the limiting cylinder 55 and the positioning plate 50. The push column 56, along with multiple sliding columns 58, moves downward along the slide groove 57. At the same time, the inner hard plate 53, along with the moving column 52, moves outward along the moving groove 51, thereby causing multiple connecting blocks 59, along with the inner hard plate 53 and the arc-shaped elastic plate 54, to stretch outward to clamp the inner shaft of the cylinder liner. Conversely, if the push column 56 is moved inward, the multiple inner hard plates 53 and the arc-shaped elastic plates 54 will loosen from the inside of the cylinder liner.

Spring 65 is fixed between guide plate 64 and mating block 61 and sleeved on the surface of guide post 63; The outer clamping block 60 is fixed to the top of the mating block 61.
[0028] In this embodiment, preferably, the limiting block 62 slides on the other end of the L-shaped right-angle groove 7.
[0029] During the implementation process, when it is necessary to clamp and fix the cylinder liner externally, press the limiting block 62. The limiting block 62 and the guide plate 64 move along the spring 65 and the guide groove towards the inside of the docking block 61, pushing the outer clamping block 60 into one end of the L-shaped right angle groove 7 through the docking block 61. The limiting block 62 is removed along the other end of the L-shaped right angle groove 7 by the counter thrust of the spring 65, thus completing the docking. The cylinder liner is placed at the center of multiple sets of external clamping blocks 60. The multiple external clamping blocks 60 move inward with the inner hard plate 53 to achieve external clamping of the cylinder liner, and move outward to release the cylinder liner surface.
[0030] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
