A hydraulic inclined hole reamer

Abstract

The invention belongs to the technical field of hydraulic reamer tools, and relates to a hydraulic inclined hole reamer. The hydraulic inclined hole reamer comprises a pump body, a fixed handle clamped to the pump body, and a driving mechanism hinged to the pump body. An oil inlet channel, a work oil cavity and an oil outlet channel are formed in the pump body, an oil storage bag is arranged in the fixed handle, and a check valve allowing oil liquid to enter the work oil cavity in one direction is detachably arranged in the oil inlet channel. An oil pump core is obliquely arranged in the pump body, one side of the inner end of the oil pump core is clamped into the oil inlet channel, and the outer end of the oil pump core abuts against the driving mechanism. A pressure relief structure allowing the oil liquid to enter the oil storage bag in one direction is arranged in the oil outlet channel. The oil pump core is obliquely arranged in the pump body, a movable handle is arranged in front of the fixed handle, space is fully utilized, the size of the whole structure is reduced, carrying is convenient, operation with one hand is convenient, the oil suction and return effect is good, and work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic hole reamer tools, and relates to a hydraulic oblique hole reamer. Background technique [0002] At present, the reamers mainly used in the market can be divided into manual reamers and electric reamers. Manual and electric reamers are mainly used in the refrigeration industry, such as refrigerators, household air conditioners, freezers, car air conditioners, central air conditioners, etc. Reaming, maintenance and installation of refrigerant pipelines and condensate pipelines. Due to the double oil channel structure of the old-fashioned reamer, the oil part of the reamer is relatively large in volume, resulting in a large structure of the entire reamer, which can only be operated with both hands when in use, which is not conducive to the carrying and handling of the user. use; and after the executive element in the oil circuit system of the old-fashioned reamer reaches the critical position, th...

Problems solved by technology

Due to the double oil channel structure of the old-fashioned reamer, the oil part of the reamer is relatively large in volume, resulting in a large structure of the entire reamer, which can only be operated with both hands when in use, which is not conducive to the carrying and handling of the user. use; and after the executive element in the oil circuit system of the old-fashioned reamer reaches the critical position, the oil in the oil circuit system can only be relieved through the forced pressure relief device, so that each time the user finishes processing a workpiece It is necessary to free up one hand to press the forced pressure relief switch, and the actuator will return to the initial position driven by its return spring. This process will take a certain amount of time for the operator, which will inevitably lead to a decrease in work efficiency.
