Abstract
The invention discloses a boring tool clamping mechanism. The boring tool clamping mechanism comprises a boring tool apron and further comprises a slide groove seat and an adjusting bolt. The boring tool apron is provided with a strip-shaped slide rail. The slide groove seat is provided with a slide groove matched with the slide rail. The axial direction of the adjusting bolt is parallel to the length direction of the slide rail, the threaded segment end of the adjusting bolt is connected with the boring tool apron, in addition, the position, in the axial direction of the adjusting bolt, of the boring tool apron is fixed, the adjusting bolt can rotate around the axis of the adjusting bolt, and the adjusting bolt is in threaded connection with the slide groove seat. According to the boring tool clamping mechanism, the position of a boring tool nose is adjusted by rotating the adjusting bolt in a linear mode, the boring tool nose is not subjected to impact force in the prior art in the process of extending into an object during adjustment, in this way, protection of the tool nose can be facilitated, and control over extending depth of the tool nose is also facilitated.

Boring machine mainly carries out the lathe of boring to the existing hole of workpiece with boring cutter, use different cutters and annex also can carry out drilling, milling, screw thread and processing excircles and end face etc.Usually, boring cutter rotates to be main motion, and the movement of boring cutter or workpiece is feed motion.It is mainly used in the fine finishining that machining high-precision hole or one-time positioning complete multiple hole, can be engaged in the processing of other machined surfaces relevant with hole fine finishining in addition.
When the object using boring cutter large to allowance in prior art carries out Boring, material table being not easy to the bed of lying of accurately braking, forcing boring cutter to change the size of bore hole in the motion of its radial direction mainly through applying external force.In existing boring cutter clamping structure, the external force that above boring cutter gos deep into material is realized mainly through the mode of hammering cutter head, and usually in a hole machined, need hammering repeatedly, above operation not only exacerbates the damage of boring cutter, is also not easy to control Boring preciseness.
Summary of the invention
The external force going deep into material for above-mentioned existing boring cutter is realized mainly through the mode of hammering cutter head, usually in a hole machined, need hammering repeatedly, more than operate the damage not only exacerbating boring cutter, be also not easy to the problem controlling Boring preciseness, the invention provides a kind of boring cutter clamping device.
For solving the problem, boring cutter clamping device provided by the invention solves problem by following technical essential: boring cutter clamping device, comprise boring cutter seat, also comprise sliding chute seat and adjusting bolt, described boring cutter seat is provided with the slide rail of bar shaped, sliding chute seat is provided with the chute matched with slide rail, the axis of described adjusting bolt is parallel with the length direction of slide rail, the thread segment end of adjusting bolt is connected with boring cutter seat, and boring cutter seat is fixed in adjusting bolt position axially, adjusting bolt can be rotated around its axis, adjusting bolt becomes to be threaded with sliding chute seat.
The boring cutter seat arranged is used for fixing boring cutter, the sliding chute seat arranged is used for being fixedly connected with the main shaft of bed of lying, in above version, rotate adjusting bolt, the length of the adjusting bolt between the tie point of adjusting bolt and sliding chute seat and boring cutter seat changes, like this, namely make boring cutter seat along runner movement, reach and change the object of boring cutter point of a knife relative to main-shaft axis distance adjustment.
Further technical scheme is:
For simplifying the structural relation that adjusting bolt is connected with boring cutter seat, the thread segment end of described adjusting bolt is fixedly connected with a roating sphere, boring cutter seat is provided with the spherical cavity mated with roating sphere, described roating sphere is positioned at spherical cavity.
For reducing stressed in the course of work of the present invention of adjusting bolt, also comprise at least one the tight fixed bolt becoming to be threaded with sliding chute seat, the thread segment end of described tight fixed bolt contacts with boring cutter seat.
For increasing the adjusting function of adjusting bolt and the anti-loosening property of adjusting bolt, the screw thread in described adjusting bolt is fine thread.
For strengthening the anti-loosening property of adjusting bolt further, described adjusting bolt is also provided with the lock nut becoming to be threaded with it.
The present invention has following beneficial effect:
The boring cutter seat arranged is used for fixing boring cutter, the sliding chute seat arranged is used for being fixedly connected with the main shaft of bed of lying, in above version, rotate adjusting bolt, the length of the adjusting bolt between the tie point of adjusting bolt and sliding chute seat and boring cutter seat changes, like this, namely make boring cutter seat along runner movement, reach and change the object of boring cutter point of a knife relative to main-shaft axis distance adjustment.The position that above process rotates adjusting bolt regulating boring cutter point of a knife is linear regulation, and in adjustment process, point of a knife to go deep in the process of object not by impulsive force of the prior art, be conducive to protecting point of a knife and control point of a knife go deep into the degree of depth.
