Oil tube control mechanism of hydraulic machine

Abstract

The invention relates to the related technical field of hydraulic machines, in particular to an oil tube control mechanism of a hydraulic machine. The oil tube control mechanism comprises a fixing frame, the surface of the fixing frame is in screw joint with a mounting rack, the inner wall of the fixing frame is in screw joint with a hydraulic pump, the surface of a threaded rod is slidably connected with a sealing seat, the sealing seat is slidably connected into a hydraulic oil tube, the surface of the mounting rack is in screw joint with a connecting tube, the surface of the connecting tubeis connected with an oil tube in a clamping mode, a connecting sleeve is welded to the surfaces of the connecting tube and the oil tube, and the connecting sleeve is welded to the inner walls of outer sleeves. The oil tube control mechanism of the hydraulic machine has the beneficial effects that the connecting tube is jointly connected with the oil tube in a clamping mode through inner clampingrings and inner clamping grooves to form an airtight structure, and the conveying leakproofness of hydraulic oil is ensured; and meanwhile, the outer sleeves are fixed to the outer ends of the connecting tube and the oil tube, the outer sleeves effectively protect the connecting tube and the oil tube, the conveying quality of the hydraulic oil is further ensured, the outer sleeves are fixed together through outer clamping rings and outer clamping grooves to form a secondary airtight structure, the structure is simple, and the oil tube control mechanism of the hydraulic machine is suitable forpopularization.

Description

technical field [0001] The invention relates to the technical field related to hydraulic machines, in particular to an oil pipe control mechanism of a hydraulic machine. Background technique [0002] Hydraulic press (also known as: hydraulic press) is a kind of machine that utilizes hydrostatic pressure and uses liquid as the working medium to transfer energy to process metal, plastic, rubber, wood, powder and other products based on Pascal's principle. Machine (main engine), power system and hydraulic control system are composed of three parts. Hydraulic machines are classified into valve hydraulic machines, liquid hydraulic machines, and engineering hydraulic machines. The oil pipe control mechanism technology of hydraulic machines is relatively mature, but there are still the following disadvantages in actual use: [0003] 1. After the hydraulic pump on the hydraulic machine has been used for a period of time, it needs to apply lubricant to its output shaft. Generally, it...

Problems solved by technology

[0003] 1. After the hydraulic pump on the hydraulic machine has been used for a period of time, it needs to apply lubricant to its output shaft. Generally, it is applied manually. The operation is complicated, and the efficiency of lubricating oil application is low. At the same time, the lubricating oil cannot be evenly applied to the output shaft. The surface of the shaft will affect the quality of the hydraulic pump;

[0004] 2. When the hydraulic machine is in use, the hydraulic oil is delivered to the hydraulic machine through the oil pipe. The delivery volume of the hydraulic oil is manually controlled, and the delivery volume of the hydraulic oil cannot be guaranteed, which will affect the normal use of the hydraulic machine, and at the same time cannot realize the hydraulic oil. Pre-storage, it is not convenient to quickly deliver hydraulic oil to the hydraulic press;

[0005] 3. The oil pipe and the connecting pipe are usually installed together by screw connection. After a long time of use, there will be a certain connection gap between the two, which will cause leakage during hydraulic oil delivery and affect the delivery quality of the hydraulic oil. At the same time, the oil pipe and the The connecting pipe is easy to break due to external force factors, and the protection effect is poor
