Description

Technical Field

[0001] This utility model belongs to the technical field of cylinder liner testing equipment, and specifically relates to a cylinder liner flaw detection positioning seat. Background Technology

[0002] After cylinder liner production, surface flaw detection is required, typically using a flaw detector. Currently, the flaw detection positioning seats used for cylinder liner flaw detection are all of the stop type, meaning they are only suitable for a specific product. When flaw detection is performed on newly developed products, cylinder liners with special processes (such as Teflon coating), or cylinder liners of different sizes, multiple flaw detection positioning seats are required, resulting in resource waste and increased costs. Therefore, a new cylinder liner flaw detection positioning seat is needed to solve these technical problems. Utility Model Content

[0003] To address the aforementioned deficiencies in the existing technology, this utility model provides a cylinder liner flaw detection positioning seat, including a positioning disk that cooperates with the rotating platform of the flaw detector, wherein the positioning disk is detachably connected to the rotating platform.

[0004] The positioning disk has multiple concentric grooves, the center of which coincides with the center of the positioning disk. The positioning disk has multiple grooves evenly distributed along its circumference, and the grooves are arranged radially along the positioning disk. Positioning elements are provided in the grooves.

[0005] It should be noted that the concentric grooves can serve as a reference when placing cylinder liners of different sizes on the positioning plate, and at the same time, they can prevent the cylinder liners from slipping, thus improving the stability of the cylinder liners on the positioning plate.

[0006] Preferably, the groove is an inverted T-groove, and the positioning element includes a T-bolt and a positioning block. The T-bolt is slidably disposed in the T-groove, and the stud of the T-bolt extends vertically upward out of the T-groove and is threadedly connected to the positioning block.

[0007] It should be noted that the cylinder liner can be positioned by sliding the T-bolt in the T-slot with any cylinder liner placed on the positioning plate. During positioning, after moving each positioning block close to the cylinder liner, tightening the positioning block will achieve the positioning of the cylinder liner. In actual use, there is a certain gap between the positioning block and the outer diameter of the cylinder liner platform, which is convenient for batch flaw detection.

[0008] Preferably, the positioning block is a nylon cylinder, and the center of the positioning block is provided with a screw hole that mates with a T-bolt.

[0009] It should be noted that the positioning block is made of nylon, which avoids the risk of damage during the flaw detection process.

[0010] Preferably, the positioning plate corresponding to one side of the groove is provided with scale lines.

[0011] It should be noted that by setting scale lines, the position of each positioning block can be accurately understood, making the positioning of each positioning block more precise. At the same time, it can be used as a reference to ensure the accurate placement of the cylinder liner.

[0012] Preferably, the positioning disk has a plurality of mounting holes evenly distributed along its circumference, and mounting bolts are fitted into the mounting holes. The positioning disk and the rotating platform are detachably connected by the mounting bolts.

[0013] Working principle: When in use, the positioning plate is fixed to the rotating platform of the flaw detector with mounting bolts. Then, the cylinder liner is placed on the positioning plate with the concentric groove. Finally, the positioning blocks and T-bolts are slid toward the cylinder liner. Finally, the positioning blocks are tightened to fix the positioning blocks to the positioning plate, so that there is a certain gap between the positioning blocks and the outer diameter of the cylinder liner, which is convenient for batch flaw detection.

[0014] This utility model also includes other components that enable the normal use of a cylinder liner flaw detection positioning seat, all of which are conventional technical means in the art. Furthermore, any devices or components not specified in this utility model, such as [examples omitted], employ conventional technical means and equipment in the art.

[0015] The beneficial effects of this utility model are: it can perform flaw detection on cylinder liners of different sizes after positioning without replacing the positioning seat, reducing tooling processing costs, lowering product costs, and improving work efficiency; moreover, the positioning is accurate and efficient, reducing damage to the outer wall of the cylinder liner, the overall structure is reasonable, the operation is simple, and it is highly practical.

[0022] Example 1

[0023] like Figure 1-3 As shown, this utility model provides a cylinder liner 1 flaw detection positioning seat, including a positioning disk 3 that cooperates with the rotating platform of the flaw detector, wherein the positioning disk 3 is detachably connected to the rotating platform;

[0024] The positioning disk 3 has multiple concentric grooves 6, the center of which coincides with the center of the positioning disk 3. Three grooves are evenly distributed circumferentially on the positioning disk 3, and these grooves are arranged radially along the positioning disk 3. Positioning elements are installed within each groove. The concentric grooves 6 serve as a reference when placing cylinder liners 1 of different sizes on the positioning disk 3, and also provide anti-slip properties for the cylinder liners 1, improving their stability on the positioning disk 3.

[0025] The groove is an inverted T-shaped groove 7. The positioning component includes a T-bolt 4 and a positioning block 2. The T-bolt is slidably disposed in the T-shaped groove, and the stud of the T-bolt extends vertically upward outside the T-shaped groove and is threadedly connected to the positioning block. The T-bolt 4 matches the T-shaped groove. The T-bolt is an M10 T-bolt. By sliding the T-bolt 4 in the T-shaped groove 7, it can be positioned with any cylinder liner 1 placed on the positioning plate 3. During positioning, after moving each positioning block 2 close to the cylinder liner 1, tightening the positioning block 2 can achieve the positioning of the cylinder liner 1. In actual use, there is a certain gap between the positioning block 2 and the outer diameter of the cylinder liner 1, which is convenient for batch flaw detection.

[0026] The positioning block 2 is a nylon cylinder, and its center has a threaded hole for engaging with the T-bolt 4. The use of nylon in the positioning block 2 avoids the risk of damage during the flaw detection process.

[0027] The positioning disk 3 corresponding to one side of the groove is provided with a scale line 9. By setting the scale line 9, the position of each positioning block 2 can be accurately known, making the positioning of each positioning block 2 more accurate. At the same time, it can be used as a reference to ensure the accurate placement of the cylinder liner 1.

[0028] The positioning disk 3 has three mounting holes 8 evenly distributed along its circumference. The mounting holes 8 are fitted with mounting bolts, and the positioning disk 3 and the rotating platform are detachably connected by the mounting bolts.

[0029] When in use, the positioning plate 3 is fixed to the rotating platform of the flaw detector with mounting bolts. During installation, a dial indicator is used to adjust the coaxiality between the positioning plate 3 and the rotating platform of the flaw detector. Then, the cylinder liner 1 is placed on the positioning plate 3 with the concentric groove 6, and the coaxiality between the cylinder liner 1 and the positioning plate 3 is adjusted with a dial indicator.

[0030] After the coaxiality adjustment is completed, slide each positioning block 2 and M10T bolt 4 toward the cylinder liner 1, and finally tighten the positioning block 2 to fix the positioning block 2 onto the positioning plate 3, so that there is a certain gap between the positioning block 2 and the outer diameter of the cylinder liner 1, which facilitates the flaw detection probe 5 of the flaw detector to perform batch flaw detection.

[0031] The embodiments of this utility model have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
