Abstract
The utility model relates to a quick-change diamond drill, comprising a drill head, an adapter and a screw; the drill head also comprises a tool bit, a steel body and an adapter tray. The tool bit is formed by mixing diamond grains with metal powder evenly and then is connected with the steel body through welding, the drill head is formed by welding the steel body into the adapter tray; the adapter stay is connected with the screw for jointing, and finally the adapter is connected with the electric tool. The utility model has the advantages that the deficiencies and shortcomings on time-consuming and toilful diamond drill change during the process of drilling can be solved. A simple quick-change diamond drill is provided, and the adapter can be used repeatedly, thereby the production cost can be reduced, and the utility model can be widely used in the processing of drill for various hard brittle materials.
Description
Technical field
The utility model relates to a kind of diamond bit, particularly a kind of can quick-replaceable quick change diamond bit, can be widely used in the boring processing of various crisp and hard materials.
Background technology
At present, the boring machining tool of crisp hard material mostly adopts diamond bit, just need pull down after the diamond segment serious wear of drill bit, changes a green bit and works on.What generally adopt in the prior art is whole bit change-over, exists to change slow, the high deficiency of use cost of efficient; The quick change mode that adopts the steel body and the adaper conical surface to connect is also arranged, but this conical surface quick change mode exists the machining accuracy height, connect defective and deficiencies such as unstable easily disengagement, adaper and electric tool that the drill bit of different size specifications of while need be joined different sizes connect, and cost is higher.
The utility model content
Change in order to overcome in the prior art that diamond bit efficient is slow, defect of high cost and deficiency, the utility model provides a kind of quick change diamond bit, not only alleviated the working strength when changing green bit, and adaper can be repeatedly used, reduce cost and increase work efficiency, can be widely used in the boring processing of various crisp and hard materials.
The technical scheme that the utility model adopted is: increase by an adaper dish transition between common diamond bit rigid body and adaper.This quick change diamond bit comprises that brill is first, adaper, screw; Bore the stem branch and comprise diamond segment, steel body, adaper dish again.Adaper and bore first (adaper dish) and use screw attachment, adaper finally connects electric tool, more only needs to unscrew screw turns adaper dish during bit change, changes to bore the stem branch and get final product, to reach purpose rapidly and efficiently.
The beneficial effects of the utility model are: solved and changed defective and the deficiency that diamond bit is relatively wasted time and energy in the drilling course of work.A kind of simple quick change diamond bit of changing is provided, and adaper can repeat repeatedly to use simultaneously, reduces the work production cost, can be widely used in the boring processing of various crisp and hard materials.

The specific embodiment
Figure of description is an enforcement preferred version of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.
As Fig. 1, shown in 3: a kind of quick change diamond bit, comprise and bore head 1, adaper 2, screw 3 bores first 1 and comprises cutter head 4, steel body 5, adaper dish 6.Cutter head 4 is mixed after sinter molding welded together with steel body 5 by diamond particles and metal dust, steel body 5 and adaper dish 6 compositions welded together bore first 1; The adaper dish 6 that bores in first 1 connects by screw 3 and adaper 2, and final adaper 2 connects electric tool.
As Fig. 2, shown in 4: because it is fastening by screw 3 and adaper 2 connections to bore head 1, and the screwing through hole on the adaper dish 6 is Pear-Shaped.When needing more bit change in the engineering construction process, only need unscrew screw 3, first 1 part is bored in the front rotate an angle and pull down from the cucurbit bottom of adaper dish 6 through holes, change the drill bit of other needs.This method is simple concerning the user, both can increase work efficiency, and the drill bit that can make the different size shape again reduces cost with same adaper; Concerning the producer, the production simple possible, and bore stem and divide unified structure, only produce a kind of adaper at a kind of rig, not only be convenient to management but also can reduce the stock and save cost.
