Abstract

The utility model relates to the technical field of cutters, in particular to a back spotfacer device of a bolt hole counter bore, which comprises a radial drilling machine. A cutter bar is fixedly embedded on a spindle of the radial drilling machine; a cutter is sleeved at the end of the cutter bar; a clamping sleeve is sleeved on the spindle; and the inner surface of the clamping sleeve is fastened on a step face of the cutter bar. The cutter can be conveniently and rapidly assembled and disassembled, the back spotfacer leads the step in the front of the cutter bar to bear axial force to meet processing requirements and save a process of screwing and loosening fixed bolts of ordinary cutters, and the cutter is fixed onto the spindle through the clamping sleeve to bear downward axial force and avoid falling of the cutter by stress.

Description

The anti-countersink tool device of bolt hole counterbore
Technical field
The utility model relates to the process tool technical field, the anti-countersink tool device of especially a kind of bolt hole counterbore.
Background technology
In the process of machine components, the particularly processing of foundry goods, forging, the screw back side that connects the end face flange often needs spot facing.Behind the manufactured bolt hole of front operation, need processing reverse side counterbore, yet, can't process counterbore from the front, can only process from the negative with general cutter because the locus is limit.
During anti-generally speaking ream, need use bolting cutter and knife bar specially at the flank of tool or end face after cutter is installed from behind,, use the expense effort in order to bear the axial force and the force of periphery.
The utility model content
The technical problems to be solved in the utility model is: for the shortcoming that solves above-mentioned existence with not enough, a kind of reliable, anti-countersink tool device of bolt hole counterbore easily and efficiently that uses is provided.
The technical scheme that its technical problem that solves the utility model adopts is: the anti-countersink tool device of a kind of bolt hole counterbore, has radial drilling machine; fixedly be embedded with knife bar on the main shaft of radial drilling machine; the end of knife bar is with cutter; be with gripping sleeve on the main shaft, the inner surface of gripping sleeve is stuck on the step surface of knife bar.
The beneficial effects of the utility model are, the anti-countersink tool device of bolt hole counterbore of the present utility model, can load and unload cutter quickly and easily, and make knife bar front step bear axial force, satisfy processing request, save general cutter and tightened the process of unclamping set bolt, and cutter is fixed on the main shaft by gripping sleeve, to bear downward axial force, avoided the stressed phenomenon that drops of cutter.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an assembly structure schematic diagram of the present utility model;
Fig. 2 is a knife bar part drawing of the present utility model;
Fig. 3 is knife part figure of the present utility model;
Fig. 4 is the right view of Fig. 3;
Fig. 5 is a gripping sleeve part drawing of the present utility model;
Fig. 6 is the right view of Fig. 5.
1. main shafts among the figure, 2. knife bar, 3. cutter, 4. gripping sleeve.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The anti-countersink tool device of bolt hole counterbore as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, preferred forms shown in Figure 6, has radial drilling machine; fixedly be embedded with knife bar 2 on the main shaft 1 of radial drilling machine; the end of knife bar 2 is with cutter 3; be with gripping sleeve 4 on the main shaft 1, the inner surface of gripping sleeve 4 is stuck on the step surface of knife bar 2.
During use the tang Mohs handle of a knife of knife bar 2 is put into radial drill main shaft 1, because cutter 3 is to turn clockwise and move upward, cutter 3 is received downward axial force.On machine tool chief axis 1, fix to clamp cover 4, make the step surface of the inner plane contact knife bar 2 of gripping sleeve 4, downward axial force is delivered on the main shaft 1 by gripping sleeve 4 again.Compressed by two hexagon socket head cap screws on the gripping sleeve 4, gripping sleeve 4 Internal Hole Deformation compress main shaft 1 periphery, and making can secure fixation.
The cutting edge of cutter 3 is upwards put into knife bar 2, and is rotated counterclockwise certain angle, and this moment, knife bar 2 had two parts just to block the end face of cutter 3, made knife bar 2 bear downward axial force.Cutter 3 is under the drive of knife bar 2, and the clockwise direction rotation also moves upward, thereby carries out processing parts.
After machining, main shaft 1 stops operating, and with the hand cutter 3 that turns clockwise, is that the face of the transmission moment of torsion of cutter 3 and knife bar 2 breaks away from fully, and withdraws from cutter 3 along knife bar 2 targeting parts that knife bar 2 upwards withdraws from workpiece along bolt hole, enters the processing of next counterbore.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
