Description

Dual oil supercharger

The present invention relates to a supercharger, in particular to a dual-oil 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. However, the traditional pressurized tool loosening equipment has the following problems: (1) the actuation speed is slow; (2) since the tool is released by hydraulic pressure and the tool is clamped by air pressure, it is easy to cause pressure due to gas mixed into the oil (3) Because the air pressure gas often contains moisture, it will cause corrosion of tools such as tool loosening cylinders, resulting in an increase in the overall cost of use.

Therefore, the double-oil supercharger type knife beating device (also can be referred to as the dual-oil supercharger) is exactly in order to solve the above-mentioned problems of the traditional supercharged type loosening knife equipment. Wherein, the conventional dual-oil supercharger mainly includes components such as a booster cylinder, an oil barrel, and an oil cup, wherein the booster cylinder includes a cylinder body, a booster cover arranged at the bottom of the cylinder body, And a component such as an oil chamber connected to the bottom of the booster cover. Wherein, the oil chamber has a shell surrounding a chamber, The shell defines a through hole extending inward from the outer peripheral surface along the radial direction of the shell 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 actions of the machine tool spindle tool release cylinder, after the pressurized cylinder has been operated for a long time, if the hydraulic oil is consumed or If there is internal leakage in the loose cutter hydraulic cylinder of the main shaft, the hydraulic oil is pressurized from the oil cup and enters the oil barrel.

Refer to the patent case No. M359688 of the Republic of China. When the liquid level in the oil cup drops to the lower level line and the lower limit sensing switch is turned on, the lower limit sensing switch will send the lower limit sensing switch open signal to The controller of the machine tool generates a warning message to notify personnel to proceed to process.

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.

However, although the above-mentioned conventional dual-oil supercharger can automatically remind personnel through the oil level sensing mechanism to avoid serious oil level imbalance, since the oil cup is arranged next to the booster cylinder and is connected to the oil The barrels are spaced apart, so in order to set up the oil cup, Additional setup space is bound to be required.

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

Thus, the novel dual-oil supercharger comprises: a booster cylinder; an oil barrel spaced apart from the booster cylinder, and including an outer tube extending up and down, and an oil cap arranged on the upper end of the outer tube. . A cover is arranged at the lower end of the outer tube and jointly defines a fluid accommodating space with the outer tube and the upper oil cover; Cover and the pull rod of the lower oil cover, the lower oil cover is provided with an inner flow channel with a first outlet and a second outlet, and a space for accommodating the inner flow channel and the outside world; an oil cup, set In the fluid containing space of the oil barrel, and including an inner tube extending up and down, the inner tube is located between the outer tube and the tie rod substantially concentrically with the outer pipe and the tie rod of the oil barrel, And the upper and lower ends of the inner tube are hermetically arranged on the upper oil cap and the lower oil cap of the oil barrel respectively, so as to separate the fluid accommodating space into a space surrounded by the inner tube and separated from the oil barrel. An oil cup space part communicated with the first outlet of the lower oil cap, and an oil barrel space part enclosed between the inner pipe and the outer pipe and communicated with the second outlet of the lower oil cap; and a section The flow needle is arranged in the accommodating space of the lower oil cover of the oil drum, and can be operated to block or not block the inner flow channel of the lower oil cover of the oil drum, when the inner flow channel When not blocked by the throttling needle, the space of the oil cup and the space of the oil barrel can be connected through the inner flow channel, so that the liquid level of the hydraulic oil in the oil cup and the oil barrel The height can be maintained at the same height.

The effect of the new model is: (1) because the inner tube is located inside the outer tube, it can greatly save the installation space of the new dual-oil supercharger, thereby reducing costs; (2) personnel can throttle the The needle is loosened so that the inner flow channel is not blocked by the throttling needle, so the oil cup space and the oil barrel space can be connected through the inner flow channel, so that the hydraulic pressure in the oil cup and the oil barrel The liquid level of the oil can be maintained at the same height, that is, the oil level is in a balanced state.
