Abstract

A dual-oil supercharger includes a booster cylinder, an oil cup, an oil barrel, and a switch valve. The on-off valve is arranged between the booster cylinder and the oil barrel and includes: a valve body, a valve stem with an oil passage, and a spring. When the machine tool clamps or releases the tool and the compressed air is supplied to the lower air inlet hole of the valve body, the compressed air pushes the valve stem to move upward, so that the first oil passage and the second oil passage of the valve body cannot pass through. The oil passage portion of the valve stem communicates, and the spring is compressed simultaneously. When the tool machine tool stops clamping and releasing the tool and the compressed air is not supplied to the lower air inlet hole of the valve body of the on-off valve, the spring returns to the natural length, so that the first oil passage of the valve body It communicates with the second oil passage through the oil passage part of the valve stem, so the oil levels of the hydraulic oil in the oil cup and the oil barrel are in a balanced state.

Description

Double oil type supercharger

The present invention relates to a supercharger, in particular to a dual-oil type supercharger.

The main function of the pressurized cylinder is to push the internal oil body with the gas input from the air pressure source, and produce a pressurized effect after passing through the passage with gradually reduced cross-sectional area, and finally output the thrust to achieve the function of higher pressure actuation. The pressurized cylinder has a wide range of uses, including assisting machine tools to change tools or assisting fixtures to clamp workpieces, etc...

Taking the dual-oil type supercharged knife cutter (also referred to as the dual-oil type supercharger) as an example, it mainly includes a booster cylinder, an oil barrel, and an oil cup and other components, wherein the booster cylinder includes A cylinder body, a booster cover arranged at the bottom of the cylinder body, and an oil chamber connected to the bottom of the booster cover and other components. Wherein, the oil chamber has a casing surrounding a chamber, and the casing defines a through hole extending inward from its outer peripheral surface along the radial direction of the casing to communicate with the chamber. Wherein, the through hole is used to install a loose cutter oil pipe.

Wherein, the oil barrel is used as an air-to-oil converter, and is provided with an upper air inlet and a lower oil outlet for installing a knife clamp oil pipe.

During the cooperative operation of the pressurized cylinder, the oil barrel and the oil cup to carry out the clamping and releasing action of the machine tool tool, after the pressurized cylinder has been operated for a long time, if the hydraulic oil is consumed or the spindle is loose If the knife hydraulic cylinder leaks, the hydraulic oil is pressurized from the oil cup and enters the oil barrel. When the liquid level in the oil cup drops to the lower level line and the lower limit sensor switch is turned on, the lower limit sensor switch will send a signal to the controller of the machine tool to generate a warning message personnel.

Conversely, when the booster cylinder is not pressurized, the high pressure in the oil barrel may push the hydraulic oil back into the oil cup, making the liquid level in the oil cup rise to an upper liquid level line and open an upper When the limit sensing switch is activated, the upper limit sensing switch will send an upper limit sensing switch activation signal to the controller of the tool machine at this time, and another warning message will be generated to notify personnel to deal with it. That is to say, after the existing dual-oil supercharger stops clamping or releasing the knife, since the oil level of the oil cup and the oil level of the oil barrel cannot automatically reach a balance, the personnel must follow the warning generated by the controller of the machine tool. It is quite inconvenient to send the message to confirm whether the oil cup needs to be maintained.

Therefore, the purpose of the present invention is to provide a dual-oil supercharger.

Therefore, the novel dual-oil supercharger is suitable for clamping or unclamping a machine tool tool, and includes a booster cylinder, an oil cup, an oil barrel, and an on-off valve. The booster cylinder includes: a cylinder body, a booster cover arranged at the bottom of the cylinder body, and a The oil chamber housing at the bottom of the booster cover has a horizontal oil passage provided with a first outlet and a second outlet. The oil cup is arranged beside the booster cylinder, and its bottom is in fluid communication with the first outlet of the transverse oil channel of the booster cover of the booster cylinder. The oil barrel is spaced from the pressurized cylinder and the oil cup, and includes a pipe body defining a fluid accommodation space capable of accommodating compressed air and hydraulic oil, and an oil side cover, wherein the oil side cover has A flow channel having an upper outlet and a lateral outlet in fluid communication with the fluid containing space. The on-off valve is arranged between the booster cylinder and the oil drum, and includes: a valve body with a first side wall, a second side wall spaced apart from the first side wall, a top wall, and a The first side wall, the second side wall and the top wall jointly define a bottom wall of an accommodating space, wherein the first side wall is provided with a second outlet connected to the accommodating space and the horizontal oil passage of the booster cylinder The second side wall is provided with a second oil passage that communicates with the accommodating space and the lateral outlet of the flow passage of the oil drum and is located higher than the first oil passage. The bottom wall is provided with a lower air intake hole; a valve rod is arranged in the accommodation space of the valve body so as to move up and down, and has an oil passage; and a spring is arranged on the top wall of the valve body between the valve stem. When the tool machine tool clamps or releases the tool and the compressed air is supplied to the lower air inlet of the valve body, the compressed air pushes the valve stem to move upward, so that the first oil passage of the valve body and the The second oil circuit cannot be connected through the oil circuit part of the valve stem to facilitate clamping or releasing the tool, and at the same time the spring is compressed, and then when the machine tool tool stops clamping and releasing the tool and the compressed air is not supplied to When the lower intake hole of the valve body of the switch valve, the spring returns to the natural length, so that the first oil of the valve body The oil passage and the second oil passage can be communicated through the oil passage portion of the valve stem, so that the liquid levels of the hydraulic oil in the oil cup and the oil barrel can be maintained at the same height.

The effect of this new model is: when the machine tool tool stops clamping and releasing the tool and the compressed air is not supplied to the lower air inlet hole of the valve body of the switch valve, the spring is a natural length, so that the valve body The first oil passage and the second oil passage can communicate through the oil passage part of the valve stem, so the liquid level height of the hydraulic oil in the oil cup and the oil barrel can be maintained at the same height, that is, oil The position is in a balanced state, so personnel do not need to go to confirm whether the oil cup needs to be maintained according to the warning message generated by the controller of the machine tool.
