Abstract
The utility model relates to a clamp and provides a lathe manual spindle clamp which aims to solve the problems that an existing positioning clamp affects machining precision and has potential safety hazards. The lathe manual spindle clamp comprises a manual spring spindle which is composed of a cone body, an anti-rotating pin, a cone sleeve and a nut, and an elastic sleeve is arranged in the circumference direction of the cone body and the cone sleeve of the manual spring spindle. The clamp is safe, reliable, low in cost, high in machining precision and convenient and fast to operate.
Description
Technical field
The utility model relates to a kind of fixture, relates in particular to a kind of lathe mandrel positioning fixture.
Background technology
The turning attachment lathe is mainly used in processing inside and outside circle cylinder, taper seat, rotoforming face, screw thread and transverse plane etc., above-mentioned each surface all forms around the rotation of lathe spindle axis, the main limit element of axle formula turning attachment is axle, be usually used in doing with the hole processing of the revolving parts of main positioning datum, as cover class, disk-like accessory.Usually design various axles or other fixtures according to the needs of processing, positioning fixture generally is divided into two kinds: a kind of clamping method that adopts two tops, as two cones of car system, but workpiece frequent contact site friction, wearing and tearing during due to two tops, affect machining accuracy, need often maintenance or change, not only affecting production efficiency but also increased production cost; Another adopts the processing method on folder one top, axle of chuck folder, and workpiece is inserted in the axle cylindrical, adopts the processing mode on folder one top, and when too small, the workpiece that processes is difficult for taking off when axle and inner hole of workpiece gap; During excesssive gap, workpiece accuracy does not reach and requires and workpiece easily skids, and damages lathe tool.Simultaneously present fixture in process engineering, due to the weight of workpiece and fixture oneself itself, produces centrifugal force without reliable safety device when High Rotation Speed, workpiece and fixture have the potential safety hazard that flies out.
Application number is that 201120196171.8 Chinese patent discloses a kind of numerically controlled lathe mandrel positioning fixture
,This utility model is made of apotting spindle, opening pressing plate and band shoulder nut.Apotting spindle is Step Shaft, and an end is provided with positioning cylinder and double-screw bolt, and the positioning cylinder excircle dimension is than the little 0.01-0.02mm of hole dimension in processing parts, and the other end is provided with clamp axis.But there is no to solve the potential safety hazard that workpiece and fixture easily fly out when High Rotation Speed.
?
The utility model content
The problem that affects machining accuracy, has potential safety hazard for solving present positioning fixture the utility model proposes the manual mandrel fixture of a kind of lathe, and this fixture is safe, reliable, cheap, and machining accuracy is high, convenient to operation.
The utility model is achieved through the following technical solutions: the manual mandrel fixture of a kind of lathe, manually mandrel fixture comprises the Manual spring axle, the Manual spring axle is comprised of cone, stop pin, tapered sleeve, nut, and the cone of Manual spring axle and the circumferencial direction of tapered sleeve are provided with resilient sleeve.Workpiece is located on resilient sleeve and axle end face with the endoporus of fine finishining, and fastening nut makes resilient sleeve outwards produce strain uniformly by cone and tapered sleeve, with the workpiece swelling, realizes the location of workpiece is clamped with this.The utility model utilizes the physical mechanics principle, designs resilient sleeve, and this resilient sleeve strain is little.
As preferably, be provided with endless groove along the circumferential outer surface of annular resilient sleeve.It is not whole the contact that endless groove makes resilient sleeve and inner hole of workpiece, and the heat that produces in process very easily loses, so the workpiece deformation amount can be neglected approximately disregard fully.
As preferably, the end that cone coordinates with the lathe spindle taper hole is made as Morse's taper.Morse's taper is the international standard of a tapering, is used for stationary fit with accurate location.Because tapering is very little, utilize the principle of frictional force, can transmit certain moment of torsion, again because be taper fit, so can dismantle easily.In the certain limit of same tapering, workpiece is free to dismounting, can not have influence on result of use again simultaneously when work, such as the taper shank drill of boring, if need to dismantle the drill bit grinding in using, again loads onto the center that can not affect drill bit after dismounting.
The cone central part of Morse's taper is provided with pull bar, and the other end of pull bar is connected with binding nut by pad.Lathe Manual spring mandrel fixture is whole to be coordinated with Morse's taper with the lathe connected mode, and strains with pull bar, and the precision of fixture own is high and stable, safe and reliable.The fixture selection is fastidious, and is reasonable in design, cheap for manufacturing cost, practicality, highly versatile.
Fixture of the present utility model is fit to workpiece with Internal hole positioning, and the revolving parts such as processing cover class, dish class are mainly used in solving the machined surface (normally cylindrical) of processing parts and the axiality between positioning datum (normally endoporus); Also can solve perpendicularity between endoporus, outer garden and end face etc.
Compared with prior art, the invention has the beneficial effects as follows:
(1) this fixture can be gathered materials on the spot, and compact conformation is reasonable, and is easy to use, and workpiece loading and unloading is quick, accurate positioning, and production efficiency is high, is fit in batch and produces in enormous quantities;
(2) high, the highly versatile of this fixture machining accuracy, fixture itself is not easy to wear, even wearing and tearing are changed resilient sleeve and got final product, there is no potential safety hazard.
Description of drawings
Fig. 1: structural representation of the present utility model;
In figure, 1: binding nut, 2: pad, 3: pull bar, 4: cone, 5: endless groove, 6: stop pin, 7: resilient sleeve, 8: tapered sleeve, 9: nut.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
As shown in Figure 1, the manual mandrel fixture of a kind of lathe, manually mandrel fixture comprises the Manual spring axle, and the Manual spring axle is comprised of cone 4, stop pin 6, tapered sleeve 8, nut 9, and the end that cone 4 coordinates with the lathe spindle taper hole is made as Morse's taper.Cone 4 central parts of Morse's taper are provided with pull bar 3, and the other end of pull bar 3 is connected with binding nut 1 by pad 2.
The cone 4 of Manual spring axle and the circumferencial direction of tapered sleeve 8 are provided with annular resilient sleeve 7.Circumferential outer surface along annular resilient sleeve 7 is provided with endless groove 5.
The manual mandrel fixture of the utility model lathe, machining accuracy is high, and general precision can reach 0.02-0.05mm, if upper order endoporus machining accuracy itself is very high, the element precision that processes is also less than 0.02-0.05mm.
