The utility model can fast and conveniently change a drill bit when the drill bit rotates in high speed, and ensures production safety and high efficiency. The utility model is especially suitable for cross arm type drill presses, is suitable for various processing parts with different dimensions and easily and accurately finds the processing positions of the parts when processing.
Description
The utility model relates to the drilling machine frock clamp, particularly a kind of anchor clamps that change drill bit fast that are loaded on drilling machine.
Present of home make drilling attachment is only applicable to machining center, bores to mill generation, and anchor clamps are more, aim at drilling machine processing and the drilling attachment that manufactures and designs seldom.For example a kind of drilling attachment that adopts No. 4 Morse's tapers and 7:24 coupling sleeve, it transmits moment of torsion and transmits with steel ball, the moment of torsion transmission can not be excessive, and damage easily, under unfavorable working condition,, iron filings many as dust for a long time, it is not in place to be easy to generate clamping.Cause taking place industrial accident.When pulling down coupling sleeve more during bit change, must just can pull down drill bit with instrument percussive drill bit homalocephalus place in connecting grooving.Do not change fast under the situation of drill bit device in present factory.Use the drilling machine processing very inconvenient, thereby influenced production efficiency.
The purpose of this utility model provides a kind of improved quick-changing type drilling attachment, can change drill bit when drill bit rotates at a high speed quickly and easily.Production security and high efficiency have been guaranteed.
A kind of quick-changing type drilling attachment described in the utility model comprises the lathe conjugation handle, the Morse's taper that is inserted in the lathe conjugation handle cavity connects cover, and be loaded on the ball bearing that Morse's taper connects cover, be equipped with in the surface groove at lathe conjugation handle rear portion to the middle part longitudinal extension that connects positioning sleeve and from the middle part that connects positioning sleeve to the connection positioning sleeve of the oblique extension of outer wall surface, connecting positioning sleeve is connected with the junction installing dual fail-safe pin that connects positioning sleeve by the groove at lathe conjugation handle rear portion with the lathe conjugation handle, the middle part that connects positioning sleeve has the placement positioning steel ball and makes steel ball expose the hole that connects the positioning sleeve inner wall surface, and the rear portion that connects positioning sleeve is with preloading spring and back-up ring and is provided with the flange on outer wall surface that stops preloading spring; The front portion that the outside that connects positioning sleeve is with the cover inwall that comes off along sliding to the oblique extension in middle part and from the middle part slip that compresses or unclamp rotating positioning ball of the portion's longitudinal extension cover that comes off backward, the rearward end of overlapping that comes off of sliding is provided with the inwall flange that blocks preloading spring and back-up ring; Morse's taper connects the anterior inner wall surface of cover and is provided with the flange that extends to the axle center, be equipped with in the middle of the flange double headed roller cap that can move forward and backward place the forward and backward shoulder of the flange outside tear the drill bit device fast open; The middle part that connects cover at the Morse's taper with the positioning ball opposite position that connects positioning sleeve has groove, and the rear portion that Morse's taper connects cover is with safe rolling bearing.
Mentality of designing of the present utility model is to be coarse positioning with the raceway that comes off.Axially move up and down 1 millimeter, under the situation that is not subjected to other radial load, linear position the best of drill bit; When being subjected to axial force, there is one to bear axial force with the coaxial wide-angle tapering of the Morse's taper of shank, its wide-angle tapering is exactly that the fine positioning that adds man-hour has changed one-time positioning processing.Improved the positional precision that adds the part in man-hour.
The utility model is torn drill bit device, pre-tightening apparatus and safe rolling bearing open fast owing to having adopted, and under the situation of therefore rotate at a high speed at drill bit, drilling machine not stopping, can change drill bit easily and fast, safely.And, still do not influence clamping or dismounting drill bit when processing cast iron, when the situation of many ashes, many bits occurring.The utility model is specially adapted to the wish-bone arm type drilling machine, is suitable for the part processing to multiple different size specification, is adding the Working position that is easy to find accurately part man-hour.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing is a kind of structural representation of quick-changing type drilling attachment.
Referring to accompanying drawing, a kind of quick-changing type drilling attachment comprises lathe conjugation handle 6, and the Morse's taper that is inserted in lathe conjugation handle 6 cavitys connects cover 2, is loaded on the bearing 3 that Morse's taper connects cover 2 rear portions, and the positioning sleeve 8 and the slip cap 10 that connect lathe conjugation handle 6.
The outside that connects positioning sleeve 8 is with the cover 10 that comes off that slides, slide to come off the front portion of cover 10 inwalls to the oblique extension in middle part, and from the middle part portion's longitudinal extension backward.Slip comes off the inwall middle part of cover 10 oblique extension with respect to connecting the positioning ball 9 that place at positioning sleeve 8 middle parts, can compress or unclamp rotating positioning ball 9.Slip cover 10 the rearward end that comes off is provided with the inwall flange that blocks preloading spring 11 and back-up ring 12.
The inner wall surface that Morse's taper connects cover 2 front portions is provided with the flange that extends to the axle center, be equipped with in the middle of the flange can move forward and backward tear drill bit device 1 fast open.Tear the double headed roller cap of drill bit device 1 fast open, two places the outside of the forward and backward shoulder of flange.
The middle part that Morse's taper connects cover 2 has groove, and groove is corresponding with the position of the positioning ball 9 that connects positioning sleeve 8.The rear portion that Morse's taper connects cover 2 is with safe rolling bearing 3.
In the safe rolling bearing 3 at least three balls 4 are housed, ball 4 is spacing by screw 5.The outer surface of safe rolling bearing 3 is spill, is convenient to finger and pinches.
Positioning ball 9 holes that connect positioning sleeve 8 middle parts have more than three.
During use, drill bit is loaded on Morse's taper connects in the cover 2, the drill bit homalocephalus embeds Morse's taper and connects cover 2 inner chambers, and one that tears drill bit device 1 fast open is just withstood the drill bit homalocephalus, and drill bit carries out work.When needs more during bit change, can not stop, under the situation that drill bit rotates at a high speed, pinch safe rolling bearing 3 with hand, pull down drill bit, and clubhaul, the other end of tearing drill bit device 1 fast open is beaten on work top, and drill bit is just tear-away, has realized changeing fast the action of drill bit.
Slip comes off cover 10 because the effect of preloading spring 11 and positioning ball 9 can guarantee the rotation and the loading and unloading of drill bit with connecting tightly clamping of positioning sleeve 8.
