Abstract
The utility model discloses a vertical type center hole drilling device. The vertical type center hole drilling device comprises a machine frame with a hollow inside, the top of the machine frame is provided with a cylinder, a centre which is connected with the cylinder in a power mode is arranged under the cylinder, the center is arranged inside a cavity of the machine frame, the bottom of the cavity of the machine frame, which is arranged opposite to the center, is provided with a three-jaw chuck, the bottom of the three-jaw chuck is provided with a motor for controlling the fastening degree of the three-jaw chunk, and a control handle for controlling the center to drill downwards is arranged beside the three-jaw chunk. The vertical type center hole drilling device is simple in structure and convenient to use; not only the labor intensity is reduced and the production efficiency is high, but also the concentricity of a center hole relative to a spigot is controlled within 0.1 after improvement and the assembling, press-fitting, straightening and dynamic balance performances are significantly improved.
Description
Technical field
The utility model relates to the auto parts machinery production technical field, is specifically related to a kind of vertical drill centers equipment.
Background technology
The big or small kind of power transmission shaft part is numerous, wherein because some heavy power transmission shaft part quality is heavier, so on engine lathe during drill centers, because inconvenience during clamping, the overproof phenomenon of jerk value behind the centre bore appears boring in regular meeting.The overproof main cause of centre bore jerk value is that workpiece is big from weight, easily drops during the drill centers clamping on horizontal engine lathe, and then influences product quality.The relative seam jerk value of centre bore is overproof have been had a strong impact on assembling and has press-fited alignment and dynamic balance performance.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and can guarantee the power transmission shaft balance quality, alleviates operating personnel's labour intensity, employed vertical drill centers equipment in beating heavy weld yoke fabrication hole operation.
A kind of vertical drill centers equipment, the frame that comprises inner hollow, described frame top is provided with cylinder, described cylinder bottom is provided be connected with its power top, the described top cavity that is positioned at frame, with at the bottom of the cavity of the top frame that is oppositely arranged scroll chuck is installed, described scroll chuck bottom is equipped with control, and it adds the motor of tightness, the other joystick that is provided with the top downward drilling of control of described scroll chuck.
The utility model is simple in structure, and is easy to use, not only alleviated labour intensity, the production efficiency height, and improve the relative seam concentricity control in rear center hole in 0.1, assembling press-fits alignment, dynamic balance performance is significantly improved.
