Abstract
The utility model discloses an improved drilling tool, which comprises a bottom plate. A drill plate is arranged on the bottom plate and fixedly connected with the bottom plate by positioning columns, each positioning column is positioned on one corresponding side of the drill plate and fixedly welded with the bottom plate, a profiling plate is arranged on the lower side of the drill plate, a positioning plug pin is arranged on the profiling plate and positioned at a corner of the profiling plate, a drill bushing I is arranged on the drill plate and is positioned at the center of the drill plate, and the lower end of the drill bushing I penetrates through the drill plate to be fixedly connected with the drill plate. Two holes are arranged on two sides of the drill plate, the positioning columns are mounted on the bottom plate and match with the two holes to realize positioning, and accordingly the improved drilling tool has the advantages of high accuracy and easiness in manufacture. In addition, the tool can be quickly changed by the aid of opening washers, and efficiency is improved; an appearance positioning mode is changed into a central column positioning mode, and machining precision is enhanced, and a quick change device is designed, the opening washers are drawn out by means of loosening nuts, so that the drill plate can be taken down, and clamping time is shortened.
Description
Technical field
The utility model relates to a kind of frock, especially relates to a kind of modified drilling tool, belongs to field of machining.
Background technology
Machining manufacturing is at present all developing to mass, scale direction, and the frock that adopts highly effective is the important channel of improving the quality of production, and reasonably frock can significantly reduce the disqualification rate of product, improves the quality of products.Existing drilling tool generally adopts workpiece profile location; From precision still is all to have the certain designed defective the reliability, and frock in use loads and unloads trouble, and clamping efficient can not get effective raising; Make process waste time and energy; Wasted many times and manpower,, be badly in need of a kind of follow-on drilling tool and change the status quo to above shortcoming.
The utility model content
To the deficiency that prior art exists, the utility model technical problem to be solved is that a kind of modified drilling tool is provided; Precision is high, safe and reliable, practicality and high efficiency; In large-scale production, can improve the quality of products greatly,, improve clamping efficient through the design quick-changing mechanism.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is a kind of modified drilling tool; Comprise end meal, pull and be provided with bushing plate at its end, and bushing plate is fixedly connected with base plate through reference column; Reference column is positioned at a side of bushing plate, the reference column and the end pull between welding fixing, the below of bushing plate is provided with the gauge finder gauge finder and is provided with fastening screw; Fastening screw is positioned at a jiao of gauge finder, and bushing plate is provided with drill bushing I, and drill bushing I is positioned at lower end, bushing plate center and passes bushing plate and be fixedly connected with bushing plate; Also be provided with drill bushing II on the gauge finder, drill bushing II is arranged at fastening screw with on one side one jiao.
Optimize, above-mentioned modified drilling tool, its reference column is provided with nut, is provided with open washer between nut and the bushing plate, and bushing plate is fixed through nut and reference column.
The modified drilling tool of the utility model according to being simple and easy to use principle, is opened two holes with the bushing plate both sides, and installing and locating post on base plate, reference column cooperate with two holes realizes the location, thereby makes it have high accuracy and the characteristics that are easy to make.In addition, realize frock quick change function, raise the efficiency through utilizing open washer.Change the profile location into the newel location, improved machining accuracy.Designed fast replacing device, through loose nut, open washer has been extracted out, bushing plate just can take off, and need not reduce the clamping time at every turn all with the nut pine on earth, and the reference column bottom is with after base plate cooperates, and is stable through the spot welding raising.Detent mechanism is carried out suitable heat treatment, improve its wearability.
Description of drawings
Below in conjunction with accompanying drawing and embodiment to the utility model further explain;
Fig. 1 is the structural representation of the utility model;
