The utility model discloses will originally adorn the O shape sealing washer cancellation at the cylinder body external diameter to on will designing two inlet ports at the cylinder body external diameter and move to mounting flange, the hydro-cylinder mounting hole that corresponds is straight hole, and no step hole has simplified the processing of hydro-cylinder mounting hole greatly.
Description
Technical Field
The utility model relates to a type hydro-cylinder technical field is examined to gas, especially relates to a type hydro-cylinder inlet structure is examined to rotatory built-in gas.
Background
As shown in fig. 3, the outer diameter of the existing air detection type oil cylinder is provided with two air inlets, and the upper side and the lower side of each air inlet are respectively provided with two O-shaped sealing rings. As shown in fig. 4, a cylinder mounting hole 6 is designed on the jig, an air inlet passage is drilled in the cylinder mounting hole 6, and the cylinder mounting hole 6 needs to be processed with a stepped hole corresponding to the O-ring. When the oil cylinder sealing device is used, the oil cylinder is arranged in the oil cylinder mounting hole 6, and the sealing ring of the outer diameter of the oil cylinder is matched with the inner diameter of the mounting hole to seal the air passage. There are several disadvantages:
1. the annular groove of the outer diameter of the oil cylinder is used for installing an O-shaped sealing ring, and an oil circuit in the oil cylinder is relatively close to the annular groove of the outer diameter of the oil cylinder, so that the edge is easily broken during processing, and the product is scrapped;
2. when the O-shaped sealing ring of the outer diameter of the oil cylinder is installed and enters the oil cylinder installation hole 6, the O-shaped sealing ring is easily cut off by the annular groove of the outer diameter of the oil cylinder, and sealing is affected;
3. after the oil cylinder is arranged in the oil cylinder mounting hole 6, the O-shaped sealing ring is in interference fit with the oil cylinder mounting hole 6, and the O-shaped sealing ring is tightly matched with the oil cylinder mounting hole, so that the oil cylinder is difficult to assemble and disassemble and is not easy to assemble and disassemble;
4. the oil cylinder mounting hole 6 is difficult to machine, the requirements on surface roughness, inner hole precision and chamfering of an inner hole are high, and the machining cost of the clamp plate is increased.
The conventional air-detecting type cylinder has problems that the conventional air-detecting type cylinder is disclosed in a conventional patent with application number CN211525230U, and the conventional air-detecting type rotary oil cylinder has several disadvantages as described above because a clamping detection air inlet and a release detection air inlet are both formed on the outer diameter of the cylinder.
Disclosure of Invention
The utility model aims to solve the technical problem that a type hydro-cylinder inlet structure is examined to rotatory built-in gas is provided, will originally adorn the O shape sealing washer cancellation at the cylinder body external diameter to on moving to mounting flange two inlet ports of cylinder body external diameter with the design, the hydro-cylinder mounting hole that corresponds is straight hole, and no step hole has simplified the processing of hydro-cylinder mounting hole greatly.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a rotatory built-in gas detection type hydro-cylinder inlet structure, includes the hydro-cylinder body, the hydro-cylinder body on install mounting flange, the lateral wall of this mounting flange both sides is installed respectively and is pressed from both sides tight gas detection device and release gas detection device, the mounting flange bottom surface seted up two inlet ports, an inlet port links to each other with pressing from both sides tight gas detection device, another inlet port links to each other with release gas detection device, hydro-cylinder body surface be the smooth surface.
As a supplement to the technical scheme of the utility model, inlet hole department install the sealing washer.
As right technical scheme a supplement, the sealing washer choose for use O shape sealing washer.
Has the advantages that: the utility model relates to a type hydro-cylinder inlet structure is examined to rotatory built-in gas has following several advantages: 1. the processing cost of the cylinder body and the cylinder mounting hole is reduced while the air detection and ventilation function of the cylinder is ensured; 2. the risk of cutting off the O-shaped sealing ring on the outer diameter of the oil cylinder during installation is avoided; 3. the improved oil cylinder is easier and more convenient to assemble and disassemble than the original structure.

Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
The embodiment of the utility model relates to a rotatory built-in gas detection type hydro-cylinder inlet structure, as shown in fig. 1-4, including hydro-cylinder body 1, hydro-cylinder body 1 on install mounting flange 2, the lateral wall of this mounting flange 2 both sides is installed respectively and is pressed from both sides tight gas detection device 5 and release gas detection device, 2 bottom surfaces of mounting flange seted up two inlet ports 3, an inlet port 3 links to each other with pressing from both sides tight gas detection device 5, another inlet port 3 links to each other with the release gas detection device, 1 surface of hydro-cylinder body be the smooth surface, need not process the ring channel, hydro-cylinder mounting hole 6 that hydro-cylinder body 1 corresponds is straight hole, does not have the step hole, has simplified the processing of hydro-cylinder mounting hole 6 greatly, and original hydro-cylinder surface need process out ring channel installation O shape sealing washer, and this can simplify the processing of hydro-cylinder mounting hole 6 greatly.
The utility model discloses the O shape sealing washer cancellation of original dress at the cylinder body external diameter to on moving to mounting flange 2 at two inlet ports of cylinder body external diameter with the design, during the installation, with 1 direct packing hydro-cylinder mounting holes 6 of hydro-cylinder body, with set screw locking, gaseous gas circuit on through the anchor clamps board and the sealed sealing that realizes admitting air and gas circuit after mounting flange 2 goes up the sealed combination of aligning 3.
