Abstract
The utility model provides a main hub hole chamfer processing positioning fixture, includes the chuck body and three movable jaw, is fixed with the holding ring on three movable jaw respectively, the indent cambered surface of holding ring is the work piece clamping face, the evagination cambered surface of holding ring is for fixing the stationary plane on the movable jaw, be provided with on one of them holding ring with main hub on the corresponding fixed orifices of locating hole, the fixed orifices internalization inserted the location bolt. Since the technical scheme is used, the utility model has the advantages of, it just can realize with less packing force that main hub supports the location through the special fixture, and it is reliable to support the location, and chamfering tool takes place the contact with the through -hole inner wall of main hub when avoiding main hub chamfer, guarantees product quality.
Description
Technical field
The utility model relates to a kind of fixture, the positioning fixture particularly a kind of lathe used.
Background technology
Main hub has through hole, main hub outer wall has the multiple little endoporus communicated with through hole, chamfer machining need be carried out to each little endoporus on inner hole wall, what existing chamfer machining mode generally adopted is manual chamfering, i.e. operative employee's offhand, another electric hand drill, spherical emery wheel on electric drill is stretched in the through hole of main hub, and make spherical emery wheel aim at the aperture of little endoporus, carry out chamfering, because electric drill vibration is in the course of the work larger, offhand and electric drill will swing, orifice chamfer is made not reach production requirement, when the little endoporus on main hub aimed at by the spherical emery wheel of hand-guided, spherical emery wheel is easily made to encounter main hub inwall, the main hub through-hole wall of scratch, cause the increase of percent defective.
Utility model content
For separating the problems referred to above, simple, the easy to use and fireballing main hub inner bore chamfering positioning clamp for machining of Set and Positioning of a kind of structure that the utility model provides.
The purpose of this utility model realizes by the following technical solutions, a kind of main hub inner bore chamfering positioning clamp for machining, comprise chuck body and three movable jaws, three movable jaws are fixed with locating ring respectively, the inner concave arc surface of locating ring is piece-holder face, the outer convex globoidal of locating ring is the stationary plane be fixed on movable jaw, a locating ring is provided with the fixing hole corresponding with the locating hole on main hub wherein, in fixing hole, is inserted with fastening screw actively.
The utility model clamps main hub like this: mobile three movable jaws, locating ring on three movable jaws is closed up, the end of each locating ring is posted on mutually and forms clamping cylinder together, again main nave collar platform and the longer one end of end face are put into clamping cylinder and form matched in clearance, and make the locating hole on main hub corresponding with fixing hole, finally fastening screw is inserted the locating hole on fixing hole and main hub, just can enter chamfer machining by chamfering tool, after fastening screw inserts locating hole, only slightly stretch out through hole, make that there is between fastening screw and chamfering tool larger gap, come in contact to prevent fastening screw and chamfering tool, location is reliable.
Owing to have employed technique scheme, the advantage that the utility model has, it just can realize main hub supporting and location by special fixture with less thrust, and supporting and location is reliable, when avoiding main hub chamfering, the through-hole wall of chamfering tool and main hub comes in contact, and ensures product quality.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows.
Fig. 1 is structural representation of the present utility model.
Fig. 2 be in the utility model locating ring close up after view.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect clearly and be easy to understand, below in conjunction with the drawings and specific embodiments, the utility model being further elaborated:
As shown in Figure 1, 2, the utility model comprises chuck body 1 and three movable jaws 2, three movable jaws 2 are fixed with locating ring 3 respectively, the inner concave arc surface of locating ring 3 is piece-holder face, the outer convex globoidal of locating ring 3 is be fixed on the stationary plane on movable jaw 2, a locating ring 3 is provided with the fixing hole 4 corresponding with the locating hole on main hub wherein, in fixing hole 4, is inserted with fastening screw 5 actively.
The utility model clamps main hub like this: mobile three movable jaws 2, locating ring 3 on three movable jaws 2 is closed up, the end of each locating ring 3 is posted on mutually and forms clamping cylinder together, again main nave collar platform and the longer one end of end face are put into clamping cylinder and form matched in clearance, and make the locating hole on main hub corresponding with fixing hole, finally fastening screw is inserted the locating hole on fixing hole and main hub, just can enter chamfer machining by chamfering tool, after fastening screw inserts locating hole, only slightly stretch out through hole, make that there is between fastening screw and chamfering tool larger gap, come in contact to prevent fastening screw and chamfering tool, location is reliable.See the clamped condition of Fig. 2, eliminate main hub in figure, locating ring 3 is welded on movable jaw.
As shown in Figure 2, conveniently support main hub, after the locating ring clamping on three movable jaws 2, form full circle.
As shown in Figure 1, 2, conveniently take off or insert and determine latch, the upper end of fastening screw 5 is provided with handle 6, too many in order to prevent fastening screw from inserting, between handle 6 and fixing hole, be provided with stop collar 7, the diameter of stop collar 7 is greater than the diameter of fixing hole 4.
