Description

Multifunctional syngen drill ripping bar

Technical field

The utility model relates to the drill jig that cooperates drilling machine to use, and is specifically related to a kind of multifunctional syngen drill ripping bar.

Background technology

Drilling machine is a rig main in the machining, and it has vertical, rocker-arm, model such as desk-top, and the drill jig main accessories that to be various drilling machine clamping cutter carry out hole processing.The drill jig of standard moulding at every turn can only drill bit drilling of clamping, and for equidistant or not equidistant porous part in enormous quantities, its drilling efficiency just presents obvious deficiency.

Summary of the invention

The purpose of this utility model is: a kind of multifunctional syngen drill ripping bar is provided, this drill jig not only can finish equidistantly on same station or not equidistant porous is bored together, can also carry out processing projects such as porous expands together, neat ream, neat hinge, and novel structure, principle uniqueness, easy to operate, safe and reliable, do not need to increase and decrease the original structure facility of main frame during use, thereby greatly improve the drilling machine working (machining) efficiency, expand the drilling machine processing characteristics, reduce changing the outfit the time of workpiece and cutter, reduce labour intensity.

Technical solution of the present utility model is: this drill jig is assembled by stake body and drill point body, described stake body is made up of support, cone axis, driving gear, cone axis passes through the spring wild card in the bearing saddle bore of bearing fixing at support, driving gear is fixed on the cone axis by card and B flat key in the spring, on the support around the carriage center equal portions one group of rotating shaft installing hole that distributes, more than each parts be assembled into stake body; Described drill point body is made up of drill point axle, pinion, drill body, on the middle part of drill point axle, bearing, spacer sleeve and radial thrust bearing are installed successively by check ring, by spring inner ring and A flat key pinion is installed at drill point axle small end place, fix by exterior nut cap in the bearing saddle bore of drill point axle insertion drill body, driven gear is put into drill body inner chamber and pinion, installs the U-shaped cover plate and promptly is assembled into the drill point body; Each drill point body is installed in drill body, driven gear, U-shaped cover plate on the stake body fastening through nut successively by rotating shaft, rotating shaft installing hole, a plurality of drill point body strings are contained in promptly forms multifunctional syngen drill ripping bar on the stake body.

In the multifunctional syngen drill ripping bar of the present utility model, the one group of rotating shaft installing hole that distributes around the carriage center equal portions on the support is installed long slot bore for the circular arc type rotating shaft.

In the multifunctional syngen drill ripping bar of the present utility model, there is circular cone magnetic tape trailer screwed hole the cone axis lower end.

In the multifunctional syngen drill ripping bar of the present utility model, on support, establish cross-notching.

When multifunctional syngen drill ripping bar and main frame are installed, with the endoporus of support and cone axis from bottom to top respectively cover be inserted on the main frame sleeve outer diameter and the main shaft endoporus in, cone axis and main shaft endoporus are combined closely, check the axial and radial clearance of drill point axle, should rotate flexibly without hindrancely, be locked at through bolt promptly to integrate on the external diameter of main frame sleeve by the bolt hole on the support again and finish with main frame every phenomenon.

During work, by collet and interior nut drill bit is installed on the drill point axle, the advance and retreat cutter motion of the automatic or manual pattern of multifunctional syngen drill ripping bar moves up and down along with the main frame sleeve and realizes, cone axis in the main shaft endoporus makes driving gear drive intermeshing driven gear and pinion through the B flat key, makes the collet in the drill point axle internal taper hole drive drill bit rotation realization principal cutting movement through the A flat key again.

The utlity model has following advantage: when 1. working, the stake body that is installed on the main frame sleeve does not rotate, and does not does not increase and decrease the original structure facility of main frame during installation, and this multifunctional syngen drill ripping bar uses safer than traditional drill jig more convenient operation; 2. main shaft and support are the reference for installation body with the main frame sleeve all, belong to same axis, support endoporus and the dead in line of main shaft endoporus, it satisfied cone axis when mounted with the axiality requirement of main shaft and support endoporus, thereby strengthened docking of many kinetic energy syngen drill ripping bar and main frame, very high positional and quality of fit are arranged, guaranteed that multifunctional syngen drill ripping bar can keep good whole, stability and machining accuracy in cutting movement, had the technical performance and the requirement of hole processing projects such as on same station, finishing porous is bored together, expansion together, neat ream, neat hinge; 3. around the circular arc type rotating shaft that the carriage center equal portions are disposed a plurality of drill point bodies of installation on the long slot bore are being installed on the support, when regulating the position setting angle of each drill point body on support, rotating the drill point body can make driven gear in the drill body inner chamber around driving tooth crop rotation planetary motion, requirement according to boring distance, be contained in the circular arc type rotating shaft installation long slot bore of support by the rotating shaft string again, be locked at nut on the lower surface of support, to reach the transmission and the processing request of the different pitch-rows of drilling, thereby realize equidistantly or the neat technical performance of boring of not equidistant porous, because pitch-row is adjustable, the manufacturing cost of this drill point prodigiosin deduction and exemption boring mould, reduce the boring cost, improve drilling efficiency and economic benefit; 4. the specification of multifunctional syngen drill ripping bar can be designed to seriation, according to the power of drilling machine equipment and the needs of rigidity of self and processing parts, select the stake body of different specification size, to reach the processing request that the drill point body that respective numbers is installed satisfies different apertures and hole count; 5. mounting center locating bar on the circular cone magnetic tape trailer screwed hole of cone axis lower end, the centralized positioning rod can be used as the centralized positioning reference point of multifunctional syngen drill ripping bar.
