Description
Technical field
The invention belongs to hydraulic pressure equipment and equipment technical field, particularly relate to a kind of oil cylinder oil injection structure.
Background technique
Existing oil cylinder oil injection structure is weld an oil nozzle on the sidewall of oil cylinder, oil nozzle is run through and cylinder side wall is drilled with an oil inlet hole after welding, because existing oil cylinder wall thickness is not enough, when welding and hole, cylinder side wall easily deforms, block distortion can hinder the operation of piston in cylinder body, greatly reduces the unfailing performance of oil cylinder, causes quality of product defective.Therefore, research and design one avoids cylinder side wall to be out of shape, and improve the functional reliability of oil cylinder, the oil cylinder oil injection structure improved the quality of products, tool is of great significance.
Summary of the invention
The technical problem to be solved in the present invention overcomes above-mentioned the deficiencies in the prior art exactly, and provides a kind of structure simple, cylinder side wall can be avoided to be out of shape, improve the functional reliability of oil cylinder, the oil cylinder oil injection structure improved the quality of products.
For solving the problems of the technologies described above, technological scheme of the present invention is:
A kind of oil cylinder oil injection structure, comprise cylinder block, pump nozzle is provided with at cylinder block sidewall, at cylinder block sidewall, arrange pump nozzle place and be provided with annular boss, on annular boss, vertically with pump nozzle be provided with mounting plane, on mounting plane, corresponding pump nozzle mounting point is provided with tapped hole, pump nozzle one end is provided with external thread section, coordinated with tapped hole by external thread section, pump nozzle is screwed onto in tapped hole, and described pump nozzle is provided with oil inlet hole.
Relative to mounting plane, be arranged with locating and machining plane at the opposite side of annular boss.
Described annular boss and cylinder block are structure as a whole.
The beneficial effect of technical solution of the present invention is:
1, structurally, oil cylinder oil injection structure of the present invention due at cylinder block sidewall, pump nozzle place be set be provided with annular boss, when thread mill drilling, cylinder block sidewall can not deform, and being provided with mounting plane, thread mill drilling in the plane, easily processes; Pump nozzle is fixedly connected with cylinder block screw thread, and non-solder, avoid causing cylinder block sidewall to deform because of welding completely, and employing is threaded, be convenient to installation or removal, especially, when blocking occurs pump nozzle, be easy to safeguard or change, very easy to use; Thus, overall structure is simple, can improve the functional reliability of oil cylinder, improve the quality of products.
2, structurally, annular boss of the present invention and cylinder block are structure as a whole, and avoid further because the welding cylinder side wall that brings deforms, thus improve the functional reliability of oil cylinder, improve the quality of products; Relative to mounting plane, be arranged with locating and machining plane at the opposite side of annular boss, when cylinder side wall thread mill drilling, adopt this locating and machining plane, then mix both sides fixture, convenient location and processing, improve work efficiency, saves process time; In addition, also structural type is versatile and flexible, and embodiment is more, is conducive to promotion and implementation.
3, to sum up, oil cylinder oil injection structure structure of the present invention is simple, can cylinder side wall be avoided completely to deform, improve the functional reliability of oil cylinder, improve the quality of products, and, convenient location and processing, improve work efficiency, save process time, also structural type is versatile and flexible, and embodiment is more, therefore, promotion and implementation are very suitable for.
