Oil hole drilling fixture for joint of inclined oil cylinder

Abstract

The invention discloses an oil hole drilling fixture for a joint of an inclined oil cylinder. The oil hole drilling fixture comprises a base, a compression assembly and a clamping assembly, wherein astation allowing a cylinder barrel body of the inclined oil cylinder to be placed is formed on the base, the compression assembly comprises a compression cylinder and a compression plate, a cylinder body of the compression cylinder is fixed to the base, the head end of the compression plate is fixedly connected with a piston rod of the compression cylinder, and the tail end of the compression plate extends to the upper side of the station of the base; and a cylinder body of the clamping cylinder of the clamping assembly is also fixed to the base, the clamping cylinder is a pneumatic finger cylinder, the clamping cylinder is provided with a first moving finger and a second moving finger, the head end of a first clamping plate is fixedly connected with the first moving finger of the clampingcylinder, the tail end of the first clamping plate extends to the upper side of the station of the base, and the head of the second clamping plate is fixedly connected with the second moving finger of the clamping cylinder. The drilling fixture replaces the functions of manual location and compression, thereby avoiding the shortages of low manual location accuracy, unreliable compression and lowoperation safety.

Description

technical field [0001] The invention relates to a fixture tool, in particular to an oil hole drilling tool for an inclined oil cylinder joint. Background technique [0002] Tilt cylinder is a commonly used actuator in hydraulic transmission system, such as figure 1 As shown, there are two oil pipe joints 12 on the cylinder body 11 of the inclined oil cylinder, which respectively connect external oil pipes to supply oil to the rod chamber and the rodless chamber of the oil cylinder, and the diameters of the two oil pipe joints 12 on the cylinder body 11 of the inclined oil cylinder The directions are different. During the processing of the inclined cylinder body 1, the joint 12 needs to be welded on the cylinder body 11 first, and then the oil hole of the cylinder body 11 should be drilled through after heat treatment and inner hole processing of the cylinder body 11. At the same time, the coaxiality of the oil hole of the cylinder body 11 and the inner hole of the joint 12 ...

AI Technical Summary

Problems solved by technology

[0003] The conventional drilling method in the industry for the oil inlet hole of the inclined cylinder is manual positioning, pressing the cylinder body, and drilling with a drilling machine. Due to the low accuracy of manual positioning, the coaxiality of the oil hole relative to the inner hole of the joint is poor, which has been used in the industry. It has not been effectively solved, which seriously affects the quality of drilled oil holes. It is urgent to design and manufacture automatic positioning, clamping joints, and compacting drilling tools to improve drilling quality.
