Drilling clamp for bottom inclined oil holes of hydraulic cylinder

Abstract

The invention discloses a drilling clamp for bottom inclined oil holes of a hydraulic cylinder. The drilling clamp comprises a guide positioning mechanism and a slide locking mechanism which are mounted on a bottom plate, wherein the guide positioning mechanism comprises a mounting plate standing on the bottom plate and a positioning plate perpendicularly mounted at the upper end of the mounting plate, the right side surface of the mounting plate is of a step structure, the step structure comprises a first step portion which is a vertical surface and a second step portion which is an inclinedsurface; an angle of inclination of the second step portion which is the inclined surface is the same with an included angle between the bottom inclined oil holes of the hydraulic cylinder and the vertical direction; the positioning plate is mounted on the right side surface of the first step, the lower end surface of the positioning plate is a first slope, and the included angle between the firstslope and the horizontal plane and the included angle between the bottom inclined oil holes of the hydraulic cylinder and the horizontal plane are complementary; a positioning hole is formed in the positioning plate; the slide locking mechanism comprises two parallel guide rails arranged on the bottom plate, a slide block connected to the guide rails in a sliding mode and a locking mechanism, wherein the upper plane of the slide block is a second inclined plane parallel to the lower end surface of the positioning plate, and a V-shaped groove is formed in the upper plane of the slide block along the center axis; and the drilling efficiency is at least improved by more than 20%.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, in particular to a drilling jig for drilling oblique oil holes at the bottom of a hydraulic cylinder. Background technique [0002] As a conventional cutting method, drilling is widely used in hole processing of various workpieces. Conventional bench drills, radial drilling machines and other processing equipment are mainly processed by vertical lifting and lowering of the spindle, drilling and cutting, and it is relatively easy to realize the processing of holes perpendicular to the reference plane of the part. The plane is not vertical, and there are oblique holes with included angles. [0003] The processing of oblique holes is a relatively difficult operation process, which involves many problems such as the adjustment of the clamping angle of the workpiece, the positioning offset of the drill bit, etc. The traditional processing method is to use flat-nose pliers to adjust a ce...

Conventional bench drills, radial drilling machines and other processing equipment are mainly processed by vertical lifting and lowering of the spindle, drilling and cutting, and it is relatively easy to realize the processing of holes perpendicular to the reference plane of the part. The plane is not vertical, and there is an oblique hole with an included angle

[0003] The processing of oblique holes is a relatively difficult operation process, which involves many problems such as the adjustment of the clamping angle of the workpiece, the positioning offset of the drill bit, etc. The traditional processing method is to use flat-nose pliers to adjust a certain angle, or use a machining center, Using center drilling, countersinking, and drills to achieve step-by-step cutting processing, but whether it is adjusting the angle of the flat pliers, or machining center clamping and alignment, or frequent switching of machining tools, it will take a long time, and the drill bit cannot be effectively controlled. Offset, it is not suitable for high precision, or processing of batch products
