Abstract
A chuck seat structure of a drill point grinder is characterized in that a conical hole is arranged at the front end of a chuck seat sleeve, a clamping jaw is arranged in the conical hole, a spring groove is arranged in the middle of the sleeve, an elastic device can be sleeved in the spring groove, an ejector pin is arranged at the tail end of the sleeve, the clamping jaw and the ejector pin are connected into a whole, a terrace edge is arranged at a position of the ejector pin corresponding to the elastic device and abutted to the elastic device, the ejector pin is provided with an action groove, the maximum outward and inward displacement of the ejector pin is limited by a positioning screw, and a plurality of equally divided cut grooves are arranged on the periphery of the clamping jaw. When a pressing cylinder of an ejector pin mechanism drives the ejector pin to outwardly push the ejector pin, the clamping jaw outwardly extends, and the clamping jaw is open as the cut grooves outside the clamping jaw are not limited by the conical hole at the moment. On the contrary, when the pressing cylinder of the ejector pin mechanism drives an ejector rod to inwardly retract, the ejector pin inwardly retracts under the elastic force of the elastic device, and the clamping jaw is collected as the cut grooves outside the clamping jaw are closed by being limited by the conical hole. Therefore, automatic clamping of drill points is realized, and efficiency is improved.

A kind of base of the carrier head structure of drill point grinder is characterized in that, comprising: the inside and outside holder of capstan head is provided with corresponding ejector pin mechanism and base of the carrier head with the hollow rotation seat; Wherein thimble structure radially drives the action that push rod is done outside release or inwardly shunk by cylinder pressure; Be provided with in the base of the carrier head sleeve bellmouth, can folding jaw, elastic force apparatus; When the thimble structure push rod is released, utilize the thrust of ejector pin mechanism push rod that jaw is stretched out outside bellmouth and open, simultaneously, elastic force apparatus is stretched; When the thimble structure push rod shrinks, utilize the elastic force of elastic force apparatus, it is interior and closed that jaw is retracted into bellmouth, realizes automatic gripping drill point, improved efficient.
Above-mentioned base of the carrier head structure is characterized in that: be provided with accommodation space in base of the carrier head holder inside, can supply to be installed with axle and hold assembly, interior outer sleeve and locating ring, in the opening part of accommodation space cover plate is installed in addition; The holder outside is provided with lug, can supply to be installed on fixed head, fixed head is installed on the hollow rotation seat of capstan head again; Holder and fixed head center are provided with axis hole and open-work, and axis hole can supply to wear sleeve, and open-work can supply to be provided with positioning seat; Barrel forward end is provided with bellmouth, and in bellmouth, wears jaw, and the stage casing of sleeve is provided with spring groove; Can supply sheathed elastic element, and wear thimble by the sleeve tail end, jaw and thimble connect to one; Thimble is provided with terrace edge corresponding to the elastic element place, is of use as the elastic element top, and thimble is provided with the action groove; And, be provided with the profile groove of some five equilibriums around the jaw by the outside and inside maximum displacement of set screw restriction thimble, when the cylinder pressure drive push rod of ejector pin mechanism is outwards released thimble; Jaw is protruding, and form an open configuration because the outside profile groove of jaw does not receive the restriction of bellmouth this moment; Otherwise when the cylinder pressure of ejector pin mechanism drove the inside retraction of push rod, thimble was inwardly withdrawn by the elastic force of elastic element, and the outside profile groove of jaw receives restriction and closure of bellmouth, and state is brought in formation together, has realized automatic gripping drill point.Wherein: jaw and thimble are provided with the internal and external screw thread that can join mutually.
[description of drawings]
Figure one is installed in the perspective exploded view of capstan head for the utility model;
Figure two is the solid combination sketch map of the utility model;
Figure three is the perspective exploded view of the utility model;
Figure four is the section combination sketch map of the utility model
Figure five is the relieving drill point view of the utility model;
Figure six is the clamping drill point view of the utility model.
[specific embodiment]
Below in conjunction with the specific embodiment the utility model is done further explain.
A kind of base of the carrier head structure of drill point grinder sees also shown in figure one, figure two, figure three, the figure four, and its structure comprises:
Capstan head 10 inside are provided with holder 11; Capstan head 10 outsides are provided with hollow rotation seat 12; Be provided with the bearing (not shown) between holder 11 and hollow rotation seat 12 belows; Let hollow rotation seat 12 rotation that can fix, holder 11 is provided with corresponding ejector pin mechanism 20 and base of the carrier head 30 with hollow rotation seat 12 tops, wherein:
According to the utility model design that above-mentioned each structural member is combined into, the base of the carrier head structure of the drill point grinder of the automatic gripping drill point of a kind of ability is provided, its structure of decontroling drill point automatically sees also shown in the figure five:
When the cylinder pressure 21 drive push rods 22 of ejector pin mechanism 20 are outwards released thimble 38; Thimble 38 meeting elasticity of compression device S; And it is protruding to drive jaw 37; Form open configuration because jaw 37 outside profile grooves 372 do not receive the restriction of bellmouth 351 this moment, realized the effect of automatic relieving thimble 1;
The structure of its automatic clamping drill point sees also shown in the figure six:
When the cylinder pressure of ejector pin mechanism 20 21 drives the inside retraction of push rod 22; During thimble 38, thimble 38 no longer receives the ejection of push rod 22, at this moment; Because the elastic force of elastic element S inwardly shrinks; Drive thimble 38 and inwardly shrink with jaw 37, the profile groove 372 of jaw 37 receives the restriction of bellmouth 351 and closure has realized the effect of automatic gripping drill point 1.
The above embodiment has only expressed a kind of specific embodiment of the utility model, its describe comparatively concrete with in detail, but can not therefore understand not restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
