[0029] Example:

[0030] Reference Figure 1 and Figure 2 As shown, an aluminum alloy casting oil supply device includes a bracket, on which a primary main oil supply system, a secondary auxiliary oil supply system and an oil outlet pipeline are arranged;

[0031] The primary main oil supply system, the secondary auxiliary oil supply system and the oil outlet pipeline are connected through the main three-way valve;

[0032] The primary main oil supply system includes an oil tank, a primary oil delivery pipe is arranged at the bottom of the oil tank, a check valve is arranged on the primary oil delivery pipe, and the primary oil delivery pipe is connected to the main three-way valve;

[0033] The secondary auxiliary oil supply system includes an oil cylinder and an air cylinder. The oil cylinder and the air cylinder are coaxially arranged. A secondary oil delivery pipe is arranged near one end of the oil tank. A piston is arranged inside the other end. A connecting rod is arranged on one side of the piston. The connecting rod penetrates the side wall of the oil cylinder and is connected to the output shaft of the air cylinder. The secondary oil delivery pipe is connected to the main three-way valve.

[0034] A throttle valve is provided on the oil outlet pipeline.

[0035] The oil tank of the primary main oil supply system supplies oil to the secondary auxiliary oil supply system through the primary oil pipe and the secondary oil pipe, and the secondary auxiliary oil supply system drives the piston to move in the oil cylinder through the cylinder. If the output shaft of the cylinder extends, it drives the piston to squeeze the oil in the oil cylinder, and the oil is transported out from the secondary oil pipe. The oil is transported to the oil-using position of the processing equipment through the oil outlet pipeline. If the output shaft of the cylinder contracts, it drives the piston to move toward the cylinder, so that negative pressure is generated in the oil cylinder, and the oil is sucked back into the oil cylinder. Whether to transport oil can be determined according to the working conditions of the processing equipment, which meets the production and process while reducing procurement and operating costs. It is more environmentally friendly, simple and reliable to operate.

[0036] The piston divides the inside of the oil cylinder into a first chamber and a second chamber. The side wall of the first chamber is connected to the secondary oil pipeline, and the connecting rod passes through the inner wall of the second chamber and is connected to the cylinder output shaft.

[0037] The first chamber is connected to a secondary oil pipeline, so the first chamber is filled with oil. The piston is driven to move by the output shaft of the cylinder. When the output shaft is extended, the piston moves toward the first chamber, which reduces the space of the first chamber and increases the space of the second chamber, squeezing the oil out of the first chamber and outputting it through the secondary oil pipeline. Since a one-way valve is provided on the primary oil pipeline, the oil cannot flow back from the primary oil pipeline to the oil tank, so the oil is transported from the oil outlet pipeline to the oil-using position of the connected processing equipment; when the output shaft is retracted, the piston moves toward the second chamber, which increases the space of the first chamber, so the oil pressure in the second chamber decreases, forming a relative negative pressure compared with the oil pressure in the processing equipment, thereby absorbing the oil in the processing equipment back into the first chamber. It is convenient for workers to adjust the oil supply according to the processing situation.

[0038] A base is provided at the bottom of the bracket, a mounting seat is provided on the base, a first supporting frame for supporting the oil cylinder and a second supporting frame for supporting the air cylinder are provided on the mounting seat, one end of the oil cylinder is fixed to the side wall of the bracket, and the other end is fixed to the side of the first supporting frame, one end of the air cylinder is fixed to the side wall of the bracket, and the other end is fixed to the side of the second supporting frame, and a structural reinforcement plate is provided between the adjacent ends of the oil cylinder and the air cylinder.

[0039] The secondary auxiliary oil supply system can be easily installed through the base, and the oil cylinder and the air cylinder are fixed by the first support frame and the second support frame respectively, so as to ensure that the oil cylinder and the air cylinder are fixed in position during use, and avoid position changes due to pressure problems, which may affect the normal oil supply. At the same time, the structural reinforcement plate is used to ensure the connection structure between the oil cylinder and the air cylinder, so that the air cylinder can drive the piston to move, and further ensure the normal use of the secondary auxiliary oil supply system.

[0040] The connecting rod is connected to the output shaft of the cylinder through a coupling sleeve.

[0041] The connecting rod and the output shaft of the cylinder can be conveniently connected together through the coupling sleeve, while ensuring the stability of the connection structure.

[0042] A grating ruler is arranged on the adjacent side of the second supporting frame and the oil cylinder, and the grating ruler is arranged parallel to the cylinder output shaft.

[0043] The displacement of the cylinder output shaft can be displayed by the grating ruler. Since the cylinder output shaft is connected to the piston, the displacement of the piston can be fed back. Since the grating ruler has high measurement accuracy, it is convenient to control the oil supply with high precision.

[0044] A branch three-way valve is also provided on the oil outlet pipeline, and a pressure gauge is connected to one interface of the branch three-way valve. The pressure gauge is connected to the oil outlet management through the branch three-way valve, and the oil pressure in the oil pipeline is displayed by the pressure gauge. On the one hand, it is convenient to check the oil pressure, and on the other hand, it is also convenient for workers to find oil leakage problems in time, thereby improving the safety of use.

[0045] An end pipe joint is arranged at the bottom of the oil tank, and an upper-level oil pipeline is connected to the end pipe joint.

[0046] It is convenient to connect with the primary oil pipeline through the end pipe joint, which is convenient for equipment assembly and use.

[0047] The bracket includes 4 pillars, a top beam is arranged at the top of the pillar, a base is arranged at the bottom, and a mounting plate with threaded holes is fixedly arranged on the bottom end surface of the pillar.

[0048] The bracket is fixed by a mounting plate with threaded holes to ensure the stability of the position of the oil supply device during use, ensure normal oil supply to the processing equipment, and improve the safety of processing.

[0049] When in use, the oil tank in the primary main oil supply system transports oil out through the primary oil pipe, and the oil enters the oil cylinder through the secondary oil pipe. When the processing equipment is in use, the output shaft of the cylinder extends, causing the piston to move toward the first chamber, pressing the oil in the first chamber out. Since there is a one-way valve on the primary oil pipe, the oil cannot flow back into the oil tank, so the oil is transported from the oil outlet pipeline to the oil usage position of the processing equipment; after the processing is completed, when the processing equipment does not need oil, the output shaft of the cylinder contracts, causing the piston to move toward the second chamber, thereby increasing the space in the first chamber, thereby reducing the oil pressure in the first chamber, and then causing the oil in the processing equipment to flow back to the oil cylinder.

[0050] At the same time, when in use, the displacement of the piston is measured by a grating ruler, which then reflects the amount of oil output in the cylinder, achieving precise control of the amount of oil owned.

[0051] In addition, in actual use, the cylinder is controlled by an electronic control device, and then the oil supply to the cylinder is controlled. When supplying oil, the output shaft of the cylinder is controlled by the electronic control device to make reciprocating motion, and then pulse oil is supplied to the processing equipment.

[0052] The oil supply device can supply oil or recover oil to the oil cylinder according to actual production needs, avoiding waste of oil resources, while also saving water resources used for cleaning oil, thereby reducing production costs.

[0053] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited to them. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model; in the absence of conflicts, the embodiments of the utility model and the features in the embodiments can be combined with each other. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
