Description

Technical Field

[0001] This utility model relates to the field of floating oil seal processing technology, and in particular to a vacuum fixture for floating oil seal processing. Background Technology

[0002] Floating oil seals are a common name for floating seals, belonging to the category of dynamic seals and mechanical seals. They possess superior sealing performance in harsh working environments with high levels of coal dust, silt, and moisture. These compact mechanical seals are primarily used in low-speed, heavy-load applications. They offer advantages such as wear resistance, automatic compensation after end-face wear, reliable operation, and simple structure, leading to their widespread use in coal mining machinery. Examples include bulldozer traveling mechanisms, scraper conveyor head sprocket assemblies, tunneling machine loading mechanisms and cantilever sections, and the left and right cutting drums and reducers of continuous coal mining machines.

[0003] In the field of floating oil seal processing technology, vacuum clamps are usually used to clamp and move the oil seal. However, if the center of the existing vacuum clamps is not aligned with the center of the oil seal during the clamping process, the oil seal is easily damaged, which is very inconvenient to use.

[0004] Therefore, it is necessary to provide vacuum fixtures for the machining of floating oil seals to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a vacuum fixture for processing floating oil seals, which solves the problem that if the center of the fixture is not aligned with the center of the oil seal during the process of clamping the oil seal, the oil seal will be easily crushed.

[0006] To solve the above-mentioned technical problems, the present invention provides a vacuum fixture for processing floating oil seals, comprising: a fixture body;

[0007] The clamp body has a collar slidably connected to its circumferential side, and an outer expansion cylinder is fixedly connected to the collar's circumferential side. The clamp body has four sets of side grooves, and a limit rod is fixedly connected inside each side groove. A spring is sleeved on the circumferential side of the limit rod. Four side plates are fixedly connected to the clamp body's circumferential side. Four sliding plates are fixedly connected to the inner side of the collar, and each sliding plate is slidably connected inside its corresponding side groove. A rod groove is formed through the upper end of each sliding plate, matching the limit rod. A sliding groove is formed inside the outer expansion cylinder, and a rubber rod is slidably connected inside the sliding groove. The upper end of the rubber rod is fixedly connected to the side plate.

[0008] Preferably, the upper end of the clamp is provided with an air hole, and multiple sets of air holes are provided, the positions of which are determined according to the positions of the oil seal.

[0009] Preferably, a gas collecting cover is fixedly connected to the upper end of the clamp body, and the gas collecting cover can completely cover the air hole.

[0010] Preferably, the upper end of the gas collecting cover is provided with a cover groove, through which gas can enter and exit.

[0011] Preferably, a connector is fixedly connected to the upper end of the gas collecting cover, and the connector matches the cover groove.

[0012] Preferably, a sealing ring is fixedly connected to the upper end of the connector, and the sealing ring is fixed to the upper end of the connector by an adhesive.

[0013] Compared with related technologies, the vacuum fixture for processing floating oil seals provided by this utility model has the following advantages:

[0014] Beneficial effects:

[0015] This utility model provides a vacuum fixture for processing floating oil seals. When the fixture is moved downwards to cover the oil seal, the outer expansion cylinder will first contact the table surface. As the fixture body continues to move downwards, the collar can slide upwards along the fixture body. At this time, the rubber rod slides along the slide groove. When the rubber rod slides, its bottom end will slide out from the bottom opening of the slide groove and push the oil seal. The oil seal can be aligned with the center of the fixture body through four sets of rubber rods. At this time, the fixture body moves downwards to accurately lock the oil seal into the interior of the fixture body. This mechanism can position the oil seal without crushing it. The connector can be easily connected to the air valve, and the sealing ring can seal the connection. The air collection cover can be set to facilitate the connection of each set of air holes, which is convenient for air extraction and air supply. Attached Figure Description
