Description

Technical Field

[0001] The invention relates to a surface treatment and flaw detection device, in particular to a surface treatment and flaw detection device for a large waste support roller body. Background Art

[0002] With the continuous development of modern machinery manufacturing industry, large-scale rollers have become an important part of the steel industry. Large-scale rollers have the advantages of higher hardness, better wear resistance, longer service life, and better economic benefits. Generally, large-scale rollers work under cold and hot rolling conditions. The working surface is subjected to great contact stress, shear stress and periodic bending stress. Uneven wear, fatigue cracks, peeling, indentation, and peeling are often seen on the surface. When the damage is serious, the shoulder will fall off and large pieces will peel off, which will seriously affect production safety and product quality. If it is not repaired in time, it will cause serious production accidents and cause the rollers to be scrapped. The replaced waste rollers are very easy to rust on the surface if they are not regularly repaired and maintained, and quality problems may also occur inside. For the recycling and reuse of large waste rollers, the roller sleeve is generally used for repair. Before the sleeve is inserted, the surface of the roller needs to be rust-free and polished, and flaw detection inspection should be carried out to ensure its quality and performance.

[0003] In actual production workshops, the surface treatment of large scrap rollers is often not able to be fully and effectively rust-removed and polished. Especially for some large rollers with surface quality defects, surface treatment is often required before flaw detection. For contact flaw detection, surface treatment is mainly to minimize the impact of rust on the surface of the roller on the internal detection results, and to reduce the wear of the surface contact probe. However, the processing of such large-sized workpieces is time-consuming and labor-intensive. In most cases, only some of the parts that need to be inspected are manually polished and then randomly sampled. The work efficiency is low and the sampling number is limited, which affects the actual detection accuracy. In addition, there may be defects in the parts that are not sampled, which may lead to accidents in the subsequent production and processing.

[0004] Therefore, it is necessary to design a structure that can fully grind the parts of the rollers that need to be inspected and perform random sampling, and try to achieve centralized processing. Because the hoisting process of large rollers is also very cumbersome, multiple hoisting procedures should be avoided as much as possible. Summary of the invention

[0030] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0031] like Figure 1-3 As shown, a support roller body surface treatment and flaw detection device of this embodiment includes a horizontal support truss 1, a double-layer fixed support workbench 3, a support drive roller 4, a crank rocker grinding mechanism 5 and a flaw detection slide tool holder 7.

[0032] The horizontal supporting truss 1 is mainly made of aluminum alloy, including a main support column 11, a cross bar 12, a fixed block 13 and a fixed base 14. The main support columns 11 are set up on all sides, and the cross bar 12 is fixedly connected to the top by a fixed block 13 to form a square truss structure. A fixed base 14 is arranged below the main support column 11. In a specific embodiment, in order to facilitate the left and right movement of the entire shelf, a ground track 9 is embedded in the ground, and a small pulley is arranged at the bottom of the fixed base 14, and the small pulley is embedded in the ground track 9 and moves left and right.

[0033] A supporting transmission roller 4 for supporting the processed roller 11 is arranged on the inner side of the horizontal supporting truss 1. One end of the supporting transmission roller 4 drives the processed roller 11 to rotate under the drive of a motor. During the rotation of the processed roller, all-round grinding and detection can be performed.

[0034] Two double-layer fixed support workbenches 3 are arranged on the horizontal support truss 1, and both ends of each of the double-layer fixed support workbenches 3 are sleeved on the main support column 11. The two double-layer fixed support workbenches 3 are symmetrically arranged relative to the axis of the processing roller 11 and are lifted or lowered under the guidance of the main support column 11. In a specific embodiment, the lifting and lowering of the double-layer fixed support workbenches 3 is achieved by arranging winches 2 above the fixed blocks 13 at the four corners. The winches 2 are connected to the double-layer fixed support workbenches 3 through hook cables, and the lifting and lowering movements of the double-layer fixed support workbenches 3 are achieved through motor drive. In order to ensure stability, a slide groove can also be arranged on the main support column 11, and a small pulley is arranged at the sleeve joint of the double-layer fixed support workbenches 3 and the main support column 11. The stability of the double-layer fixed support workbenches 3 during lifting and lowering is improved by moving the pulley in the slide groove.

[0035] In a specific embodiment, the upper and lower layers of the double-layer fixed support workbench 3 are fixedly welded together by a support frame to improve stability. A liftable load-bearing seat 8 is provided below the double-layer fixed support workbench 3 to support the double-layer fixed support workbench 3, ensure the stability of the overall truss during work, and can be independently moved away after work is completed.

[0036] Combination Figure 4-6 As shown, the upper middle part of the double-layer fixed support workbench 3 has an opening 32, with rollers 31 embedded at both ends, and a crank rocker grinding mechanism 5 that can move left and right in cooperation with the rollers 31 is provided at the opening 32. In a specific embodiment, the crank rocker grinding mechanism 5 includes a grinding device 51 and a rocker driving device 52, and the grinding device 51 includes two connecting parts 511 respectively installed above the rollers 31, and the two connecting parts 511 are provided with a plurality of buckles 512 for clamping the grinding belts 514, and a plurality of grinding belts 514 are straddled on the two connecting parts 511 through the buckles 512. The structure is simple and easy to disassemble and assemble, and the grinding belt 514 is tightened on the surface of the roller 11 and moved left and right for grinding. The rocker drive device 52 is fixedly connected to the lower part of the middle opening 32 of the upper layer of the double-layer fixed support workbench 3 by bolts, and is connected to the lower end of the connecting part 511 through the rocker 53 passing through the opening 32. The lower part is a motor-driven pulley, which drives the rocker 53 to move left and right, thereby driving the upper grinding device 51 to move left and right. Since the rocker 53 is located in the middle, whether the rocker 53 moves left and right can be used in the grinding process. The high-speed reciprocating multiple grinding has a better surface quality than manual grinding. At the same time, the supporting transmission roller 4 realizes the rotation of the processed roller 11, and the grinding is more comprehensive during the rotation of the roller 11.

[0037] In a specific embodiment, a fixed pressing frame 6 is arranged above the roller 31, and both ends of the fixed pressing frame 6 are fixed to the roller 31 of the upper layer of the double-layer fixed support workbench 3 by screws. A needle roller 61 is arranged on the fixed pressing frame 6, and bosses 513 are processed on both sides of the connecting portion 511. The lower surface of the boss 513 contacts the upper surface of the roller 31, and the upper surface of the boss 513 contacts the needle roller 61, that is, the needle roller 61 presses on the boss 513 to prevent the device from tilting due to force during the grinding process.

[0038] A flaw detection slide tool holder 7 for flaw detection is arranged on one side of the lower workbench of the double-layer fixed support workbench 3. The flaw detection slide tool holder 7 is connected by a lead screw. In a specific embodiment, the flaw detection slide tool holder 7 is fixed on the table surface by a base under the lead screw. A track that can move forward and backward is installed on the tool holder, and the position is fixed by tightening screws. A flaw detection instrument is placed inside, and a handle is installed at the back to facilitate the forward and backward movement of the detection device.

[0039] A movable oil brush 10 is provided on the other side of the lower workbench of the double-layer fixed support workbench 3. In a specific embodiment, the movable oil brush 10 includes a support base 101 and an oil brush device. The oil brush device is installed on the lower workbench of the double-layer fixed support workbench 3 through the support base 101. A groove table for the oil brush device to move forward and backward is provided on the support base. The oil brush device includes an oil pool 102 and an oil brush 103 provided above the oil pool through a roller. When the oil brush 103 moves forward and contacts the rotating roller body 11, the friction force drives the oil brush 103 to rotate and apply oil, and the oil brush 103 stops rotating when it moves backward. The entire oil brush device is installed on four groups of support bases 101. The forward and backward movement of the oil brush device is fixed by screws 104 at both ends and a base 105 drilled with internal threaded holes. The oil brush device slides forward and backward on the groove table on the bottom four support bases 101. The bristles of the oil brush 103 have a certain inclination, so that the oil brush 103 is fully in contact with the surface of the roller body. One side of the oil brush device is in contact with the roller body 11, and three sections of rubber scrapers 106 are installed at the front end, which are mainly used to scrape the uneven oil on the surface of the roller body 11 that contacts some oil brushes 103. The front end of each scraper 106 has an inclination, and a through hole 107 is drilled in the middle, which is connected to the oil pool 102. When the oil level in the oil pool 102 is higher than the through hole 107, the excess oil will flow into the scraper 106, which plays a role in supplementing lubrication at the contact point with the roller body 11; an arc-shaped baffle 108 is installed on the other side to prevent oil splashing and reduce loss. When the movable oil brush 10 is close to the groove table on the side of the roller 11, the oil brush contacts the roller body 11, otherwise it is separated from it. The main purpose of this design is to oil the roller body 11 before flaw detection when grinding is completed, so as to facilitate subsequent detection.
