Description

A kind of drill bit edge repair machine

Technical field

The utility model relates to the sharpener of a kind of machining with drill bit, thousands of drill bits of different size can be accomplished the drill bit edge repair machine of same angle, same precision especially.

Background technology

At present with interior mechanical processing industry such as drill bit, the multiple-cutting-edge bed, equipment such as building-block machine, used drill bit all needs to repair sword, adopt abrasive machine when repairing sword, it is by shell, motor, emery wheel is formed, the hand-held drill bit of operator is repaiied sword on the emery wheel of high speed rotating, it has following defective and deficiency: the one, and necessary operation technique height, the high-grade workman that experience is many, before guaranteeing to repair the cutting drill head, the angle of the back basil, the precision unanimity, having to, cost is long repaiies the sword time, even like this, will accomplish same angle to thousands of drill bits of different size, same precision more can't guarantee, so that influence the drilling quality of product, the 2nd, the emery wheel wheel side face of repairing behind the sword is rough and uneven in surface, for guaranteeing to repair the sword quality, must frequently change new emery wheel, the 3rd, when repairing sword, the generation noise is big, the many and contaminated environment of dust.

Summary of the invention

The purpose of this utility model is the deficiency that will overcome in the prior art, and a kind of new drill bit edge repair machine is provided, and this edge repair machine can not only accomplish the drill bit in enormous quantities of different size same angle, same precision, improve drill bit repaiies the sword quality; And its compact conformation, small and exquisite and free from environmental pollution.

The purpose of this utility model realizes with following technical scheme, the drill bit edge repair machine is made up of shell, motor, emery wheel, its technology special feature is: the bottom is equipped with and is connected golden steel diamond system emery wheel on vertical machine, the motor shaft in the shell, with the high corresponding shell of emery wheel garden side face outside perforate on the side, the angle of the center line in this hole and emery wheel longitudinal axis is 59 °～67.5 °, and promptly repairing the center line of cutting drill head and the angle of the vertical periphery of emery wheel is 59 °～67.5 °.The upper and lower pendulous device of packing in the hole, in the centre bore of pendulous device, the drill bit gripping mechanism of packing into makes on flange lower plane in the drill bit gripping mechanism and the flange in the pendulous device plane do relative motion, the spirality curved surface of its contact-making surface for coincideing and joining.Upper and lower pendulous device is by the oscillating vane ring, and flanged movable sleeve is formed.Put to add and be arranged with two fins on the blade ring, on the forward and backward inwall of shell upper, be arranged with cambered way respectively accordingly with two fins, when the oscillating vane ring is packed the shell side into, make its two fin place in the slideway respectively, in the centre bore of oscillating vane ring, the flanged movable sleeve and affixed of packing into elastic key.The last plane of flange is the spirality curved surface, by the movement in a curve of oscillating vane ring two fins in the forward and backward inwall slideway of shell; Make that pendulous device is realized from top to bottom, motion from bottom to top, make pendulous device be able to swing in 59 °～67.5 ° angular ranges, use to regulate and meet the angle of repairing the cutting drill head.In last, the drill bit gripping mechanism of packing in the central shaft hole of lower swing device, it is by the card cap, uniform active card and its flanged cutting ferrule in middle part that is connected on the card seat ring formed, bottom Connection Card sheet seat ring in the central shaft hole of card cap, the uniform wire rack that is connected on the card seat ring bottom face, active card of difference cross-under on each wire rack, active card is the right-angled trapezium sheet, porose on its lower surface, passing this hole activity is installed on the wire rack, be free state, place the cutting ferrule bottom to be in the garden cover of tapering, be that make and the corresponding tapering of active card gradient space the cutting ferrule bottom, make all active cards that are distributed on the snap ring lower end, after assembling, place in the lump in its circle cover, the upper end of cutting ferrule is with the card cap that is threaded, when card cap when screwing, impel the active card that is in the cutting ferrule to shrink in to clamp drill bit to the center.Otherwise can take out drill bit, be positioned at the flange at cutting ferrule middle part, its lower plane be provided with pendulous device in flange on the spirality curved surface that matches and join on the plane, this spirality curved surface is the movement locus of simulation drill bit forward and backward basil in repairing the sword process, its high point is the basil before the coping drills, and its low spot is the basil after the coping drills.At this moment, as repairing the cutting drill head, at first confirm the drill bit angle, pendulous device is allocated to its angle, then drill bit is inserted in the centre bore of card cap, and push to outside the cutting ferrule bottom, make bit face touch the periphery of emery wheel, to block cap and screw, and clamp drill bit, starter motor rotates emery wheel, tight gripping mechanism, aim at the grinding mouth, rotate two circles promptly 720 ° to the right, just can finish the sword of repairing of this drill bit.Take off gripping mechanism, measure the drill bit summit to cutting ferrule bottom distance, promptly drill bit is repaiied the sword height.Highly other drill bit is repaiied sword singly with this.Thereby realize the drill bit in enormous quantities of different size is accomplished the purpose of same angle, same precision.

Compared with prior art, the utility model not only can be accomplished same angle, same precision with the drill bit in enormous quantities of different size, improves drilling quality, reduce cost, and its compact conformation, small and exquisite, floor space is little, and is easy to operate and free from environmental pollution.
