Description

TECHNICAL FIELD

[0001] The utility model relates to O type ring diameter measuring equipment technical field, specifically is a kind of O type ring diameter automatic measurement platform. BACKGROUND

[0002] In modern industrial production, sealing technology is an important link to ensure the normal operation and safety of equipment. O-ring, as a widely used rubber sealing element, is widely used in various mechanical equipment, such as mechanical seal, oil seal, air cylinder, hydraulic system, automobile engine, aerospace equipment and other industrial scenes requiring sealing, due to its simple structure, reliable sealing performance, easy installation and other advantages. The dimensional accuracy of O-ring is directly related to its sealing effect and the reliability of equipment operation. If the size of O-ring is not suitable, it may cause sealing failure, triggering equipment failure and even safety accidents. Therefore, in the process of equipment maintenance and maintenance, accurate measurement of the diameter of O-ring is the basis to ensure the normal operation of equipment.

[0003] However, the existing detection equipment has obvious limitations in function. These devices can only measure the diameter of O-ring, but cannot detect the defects on the surface of O-ring. For example, wear and tear during use may cause scratches, dents, bumps or other microscopic defects. These defects, although they do not affect the diameter measurement results, may cause sealing failure in actual use. Therefore, the current detection process usually needs to be detected twice after preliminary measurement to identify and mark these potential defects. This manual detection method has many problems. First, manual detection is inefficient and difficult to meet the needs of large-scale production and rapid maintenance. Second, the limitations of human observation make it difficult to accurately identify the subtle defects on the surface of O-ring, which may lead to missed detection or misjudgment.

[0004] In specific industrial scenarios, such as the electrolytic copper foil industry, the application of O-ring is more critical. In the production process of electrolytic copper foil, the titanium roller on the foil machine needs to use a larger size O-ring to block the overflow of copper sulfate electrolyte from the side of the titanium roller. The dimensional accuracy and sealing performance of this liquid blocking O-ring directly affect the production quality of electrolytic copper foil and the stability of equipment operation. However, the existing detection equipment cannot meet the efficient and accurate detection needs in this specific scenario. Therefore, it is particularly important to develop a device that can automatically measure the diameter of O-ring and screen whether it is within the error tolerance range.

[0005] This invention addresses the aforementioned problems by proposing a diameter measuring device for the O-rings used in the electrolytic copper foil production machine's liquid-blocking mechanism. This device can automatically measure the diameter of the O-ring before installation and for reused O-rings, and screen whether the diameter of reused O-rings is within the allowable error range. This device effectively improves the efficiency and accuracy of O-ring inspection, reduces errors from manual inspection, and ensures the normal operation and sealing reliability of electrolytic copper foil production equipment.

[0038] Working principle: According to Figure 1 As shown, when it is necessary to detect the diameter of the O-ring, the O-ring is placed on the drive roller 2, auxiliary roller 3, fixed roller 4 and moving roller 5. The control threaded shaft 601 is rotated, and the other control threaded shafts 601 are rotated at the same time through the sprocket and chain 603. This causes the movable sleeve 602 connected to the threaded shaft 601 to move the moving roller 5, which stretches the O-ring. Then, the diameter of the O-ring is quickly calculated according to the scale value near the moving roller 5 on the table.

[0039] When it is needed to detect whether there is defect on the O-ring, the threaded shaft 702 is rotated to drive the two sliding sleeves 703 to move relative to each other, so that the first half ring 704 and the second half ring 705 connected to the sliding sleeves 703 are close to each other and are combined to form a circular ring and are sleeved outside the O-ring, the balls 709 on the end of the movable rods 708 on the inner side of the first half ring 704 and the second half ring 705 are in contact with the outer wall of the O-ring at each angle, then the driving roller 2 is driven to rotate to drive the taut O-ring to rotate, if there is a defect such as a depression or a protrusion on a certain area of the O-ring, when the ball 709 passes through, if it is a depression, the movable rod 708 and the ball 709 move outwardly relative to the pipe body 706, at this time, the opening 711 on one side of the movable rod 708 is aligned with the first branch pipe 712, under the pressure of the pressure spring 717 and the piston rod 716, the fluorescent agent liquid or the ink liquid in the box 715 enters the flow channel 710 on the movable rod 708 through the liquid channel 714 and the first branch pipe 712, and under the cooperation of the rotation of the ball 709, the fluorescent agent liquid or the ink liquid is applied to the depression of the O-ring;

[0040] If the area on the O-ring is a protrusion, the movable rod 708 and the ball 709 will be moved inwardly relative to the corresponding pipe body 706, at this time, the other opening 711 on the movable rod 708 is aligned with the second branch pipe 713, then the fluorescent agent liquid or the ink liquid in the box 715 enters the flow channel 710 on the movable rod 708 through the liquid channel 714, and is applied in cooperation with the ball 709;

[0041] When the area on the O-ring after being applied passes through the light of the light lamp 9, it is more conspicuous, so that the staff can quickly understand that there is a defect on the area of the O-ring, and it is also convenient for subsequent maintenance to quickly locate and repair, which is the working principle of the O-ring diameter automatic measurement platform.
