Description
Technical field
This utility model belongs to lathe drilling field, and in particular to a kind of lathe depthkeeping drill unit, is applied to lathe, from
Dynamic drilling, reaming, the rapid processing at flat hole bottom simultaneously realize accurate depthkeeping.
Background technology
Engine lathe utilizes barrel of tail stock Morse's taper in part processing at present, realizes being accurately positioned for drilling tool,
Mobile tailstock, swinging handle realize that bore expanded hole works, using larger diameter drill bit, during Manual drilling, high labor intensive,
In reaming, handwheel is shaken, feed speed is uneven, and when being that 180 ° of drill bits are flat with drift angle, hole depth is difficult precise control.
Utility model content
It is a kind of lathe depthkeeping drill unit that the purpose of this utility model is provided, when solving batch production, high labor intensive,
Feed the problem that uneven, hole depth is difficult precise control.
The technical solution of the utility model is：A kind of lathe depthkeeping drill unit, it is characterised in that：Including clamp body 1, cone
Two lobe gripping sleeve 3 of shape, Mohs cone drill holder 4, adjustable depth bracing frame 7, bearing roller 8 and drill bit 6；Two lobe gripping sleeve of taper
3 are put in the location hole being engaged with clamp body 1, and Mohs cone drill holder 4 is put into two lobe of taper to be stepped up in set 3, and drill bit 6 passes through
Morse reducing sleeve 4 is fixedly connected with two lobe gripping sleeve 3 of taper；Bearing roller 8 is fixed on 7 front end of adjustable depth bracing frame, bearing
Vertical dimension between 8 arcwall face front end of roller and 7 cutting edge of drill bit is drilling depth, adjustable depth bracing frame 7 and clamp body 1
Bottom is fixedly connected.
Beneficial effect：This utility model is spacing by bearing roller, realizes drilling, reaming peaceful bottom hole and walks automatically
Knife cuts and precise control drilling depth, and labor intensity is low, high in machining efficiency.

Specific embodiment
To make the purpose of this utility model, content and advantage clearer, specific embodiment of the present utility model is made
Describe in further detail.
This utility model provides a kind of lathe depthkeeping drill unit, including clamp body 1, two lobe gripping sleeve 3, Mohs of taper cone
Body drill holder 4, adjustable depth bracing frame 7, bearing roller 8 and drill bit 6；
Two lobe gripping sleeve 3 of taper is put in the location hole being engaged with clamp body 1, and Mohs cone drill holder 4 is put into taper
Two lobes step up in set 3, and the drill bit 6 at drilling/reaming/flat hole bottom is put in Morse reducing sleeve 4 to be realized being accurately positioned and by screwing
Screw 10,11 is realized clamping, and bearing roller 8 is fixed on adjustable depth bracing frame 7, by adjusting adjustable depth bracing frame 7
Extension elongation controls the vertical dimension between 8 front end arcwall face of bearing roller and 7 cutting edge of drill bit, so as to adjust drilling depth,
Adjustable depth bracing frame 7 is fixedly connected with 1 bottom of clamp body by tightening screw 12,13.1 clamping of clamp body is in lathe tool platform
On 2, by centering, make 6 center of rotation of drill bit and lathe center of rotation overlap, screw knife platform screw 14,15 clamping device bodies 1,
Workpiece 9 rotates, the band movable knife rack 2 length feed feed cutting of lathe saddle, and contact 9 end face of workpiece of bearing roller 8, roller are rotated
Reach precise control cutting depth requirement.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, some improvement and deformation can also be made, these change
Enter and deform also to should be regarded as protection domain of the present utility model.
