Description

Technical Field

[0001] The invention belongs to the technical field of flaw detection equipment, and in particular relates to an automatic flaw detection device for a cylinder liner. Background Art

[0002] Cylinder liner flaw detection is used to detect defects that may exist inside or on the surface of the cylinder liner that are difficult to detect with the naked eye, such as cracks, slag inclusions, pores, etc. If these defects are not discovered and handled in time, they may have a serious impact on the performance and life of the cylinder liner, and even cause engine failure or safety accidents. Therefore, cylinder liner flaw detection is an important link to ensure the normal operation of the engine and extend its service life, thereby preventing accidents caused by cylinder liner failures. In addition, during the maintenance process, flaw detection can quickly and accurately locate the defective position of the cylinder liner, so that a targeted maintenance plan can be formulated, which helps to improve maintenance efficiency and reduce maintenance time and costs.

[0003] The patent application number is 201910361736.4. It discloses an automatic flaw detection device for cylinder sleeves. The application coordinates three mechanisms, namely, a rotating platform, a flaw detection mechanism, and a working platform. During use, the relative positions of the inner wall probe and the outer wall probe with the cylinder sleeve can be freely adjusted to detect the inner and outer walls of the cylinder sleeve. In combination with the prior art and in view of the above application, during use, since the cylinder sleeve is vertically mounted on the rotating platform during use, during the flaw detection process, if the cylinder sleeve has a certain length, the other end of the cylinder sleeve cannot be detected during the flaw detection. At this time, the cylinder sleeve needs to be disassembled and rotated 180 degrees to be reinstalled. This process is relatively cumbersome and needs to be disassembled and reassembled, which affects the work efficiency during flaw detection and reduces the use and functionality of the device.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1

[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a technical solution: cylinder liner flaw detection is an important means to ensure the normal operation of the engine and extend its service life. By selecting appropriate flaw detection methods and equipment, potential problems of the cylinder liner can be discovered in time during the production and maintenance process, thereby ensuring the safety and reliability of the engine. An automatic cylinder liner flaw detection device includes a base 100, a support frame 101 is fixedly installed on one side of the top of the base 100, a lifting limit column 201 for driving the lifting is installed on the top of the support frame 101, and a lifting column 202 for limiting during the lifting process is also provided. The rotating flaw detection assembly includes a flaw detection top plate 200, and a lifting guide limit block 203 is fixedly installed on one side of the flaw detection top plate 200. The flaw detection top plate 200 is limitedly lifted and lowered on the lifting limit column 201 and the lifting column 202 by the lifting guide limit block 203. At the same time, a direction-changing motor 204 is fixedly installed on the top of the flaw detection top plate 200, and a rotatable rotating hanging plate 205 is installed at one end of the direction-changing motor 204 at the bottom of the flaw detection top plate 200. When working, the rotating rotating hanging plate 205 can enter the interior of the cylinder liner from different directions for flaw detection, thereby improving the functionality of the structure.

[0029] Specifically, the rotating hanging plate 205 is driven to rotate by the reversing motor 204, and a movable slide rail 206 is installed at the bottom of the rotating hanging plate 205, and a movable moving seat 207 is arranged at the bottom of the moving slide rail 206, and the moving seat 207 can be adjusted in lateral displacement on the moving slide rail 206, and an outer wall probe 208 is arranged at the bottom of the moving seat 207, and an inner wall flaw detection hanger 209 is installed on one side of the moving seat 207. When the flaw detection device in the application is used to detect the cylinder sleeve, the cylinder sleeve to be detected is placed on the clamping frame 300 and is clamped and fixed laterally by the cylinder sleeve clamping rod 301. After clamping and fixing, the flaw detection top plate 200 is lifted and lowered by the lifting guide limit block 203 on the lifting limit column 201 and the lifting column 202. During the descent, the moving seat 207 moves to the end of the movable slide rail 206. When the inner wall flaw detection hanger 209 is lowered to a suitable height , the movable slide rail 206 drives the movable seat 207 to move slowly forward again, and performs flaw detection on the cylinder sleeve through the outer wall probe 208 installed at the bottom of the movable seat 207 and the inner wall probe 211 installed on the inner wall flaw detection rod 210. At the same time, the outer wall probe 208 is opposite to the inner wall probe 211, and the corresponding part can be better detected. In addition, during flaw detection, if the length of the cylinder sleeve is too long, after the flaw detection at one end is completed, the movable seat 207 moves to drive the inner wall flaw detection hanger 209 to exit the cylinder, and then the reversing motor 204 works to drive the rotating hanging plate 205 to rotate 180 degrees, so that the inner wall flaw detection hanger 209 enters from the other end of the horizontally installed cylinder sleeve, and performs flaw detection again from the other end. Through the effect of this structure, cylinder sleeves of different lengths can be detected, and flaw detection is better while ensuring the integrity of flaw detection, thereby improving the convenience and work efficiency during flaw detection and the practicality of the device.

When adjusting, loosen the hand nut on the fixing screw 213, and then move the fixing screw 213 in the adjustment groove 212 to limit the distance between the inner wall probe 211 and the outer wall probe 208, and then tighten the nut on the fixing screw 213 to fix it. By adjusting the distance between the outer wall probe 208 and the inner wall probe 211, cylinder liners of different thicknesses can be better used for flaw detection, thereby improving the display effect of detection and further improving the practicality and functionality of the device.

[0032] Specifically, an inner wall probe 211 is fixedly installed on the top of one end of the inner wall flaw detection rod 210, and the inner wall probe 211 and the outer wall probe 208 are installed on the same vertical center line. During the flaw detection process, the damage degree of the cylinder liner can be better detected by simultaneously detecting inside and outside. The inner wall flaw detection hanger 209 and the inner wall flaw detection rod 210 can be adjusted in lateral displacement on the movable slide rail 206 through the movable seat 207, and the rotating hanging plate 205 can be driven by the reversing motor 204 to rotate for angle adjustment, which facilitates flaw detection and improves the practicality of the device.

The inner side of the holding frame 300 is provided with a lifting cylinder 306 for driving the positioning lifting rod 308 to lift and the cylinder sleeve clamping rod 301 to rotate. When the cylinder sleeve is placed on the holding frame 300 for fixing, after the cylinder sleeve is placed horizontally, the lifting cylinder 306 located in the lifting groove 305 on the inner side of the holding frame 300 works The lifting support plate 307 is pushed up and down in the lifting slot 305, and the positioning lifting rod 308 is driven to lift a certain height at the same time. The cylinder sleeve is supported by the positioning driving wheel 310 at the top of the positioning lifting rod 308. When the positioning lifting rod 308 rises, the clamping rod adjusting guide wheel 304 at one end of the cylinder sleeve clamping rod 301 is pushed to rotate and change the angle through the top changing inclined platform 309 with an inclined surface. When the positioning lifting rod 308 is lifted, the top of the cylinder sleeve clamping rod 301 rotates inwardly, gradually changes the clamping diameter, and passes through the cylinder sleeve. The sleeve clamping wheel 302 clamps the placed cylinder sleeve. Through the adaptive clamping of the positioning drive wheel 310 and the cylinder sleeve clamping wheel 302, cylinder sleeves of different diameters can be clamped while ensuring the convenience and stability of clamping. At the same time, after clamping, in order to better detect flaws, the rotating motor 311 can drive the positioning drive wheel 310 to rotate, and the rotating positioning drive wheel 310 can drive the placed cylinder sleeve to rotate, so that rotational flaw detection can be completed during flaw detection, which not only improves flaw detection, but also improves the practicability and functionality of the device.

[0035] Specifically, a positioning driving wheel 310 is rotatably installed on the top of the positioning lifting rod 308, and a rotating motor 311 is installed on one end of the positioning driving wheel 310 on the positioning lifting rod 308.
