Abstract
The utility model discloses a locating clamp which comprises a core shaft component and two sets of locating and locking components which are arranged at the two ends of the core shaft component respectively and used for fixing a workpiece. The core shaft component comprises a core shaft, a first connecting sleeve and a second connecting sleeve, wherein the first connecting sleeve and the second connecting sleeve are arranged on the outer circle of the core shaft and used for abutting against the wall of an inner hole of the workpiece. The locating clamp can effectively clamp the workpiece with a high requirement for inner hole locating precision, is high in locating precision and good in effect in actual use, and meets using requirements.
Description
Technical field
The utility model relates to mechanical field, relates in particular to the special tooling of cylinder class with the amount of unbalance of the measuring workpieces of Internal hole positioning, has the characteristics such as positioning precision is high, convenient mounting and clamping.
Background technology
Can not produce centrifugal force when the barycenter of slewing parts does not overlap with the revolution axle center, this centrifugal force can make part in use produce ill effect: cause the vibration of equipment, the service life that affects block bearing, generation noise etc.
The effect of dynamic balancing machine is exactly the angle that detects the distribution of the amount of unbalance of workpiece and amount of unbalance, thereby instructs the amount of unbalance (increasing the weight of and the duplicate removal method) of eliminating workpiece.Some special workpiece (as cylinder class workpiece) must be made special-purpose frock, just can be bearing on the balancing machine roller and be detected.This has just proposed following requirement to frock:
1, can transmit the power that is enough to drive the workpiece rotation.
2, high positioning precision (orientation axis with duty lower axis overlap performance good) is arranged.
3, special tool is equipped with high balance quality (amount of unbalance of frock itself is very little), otherwise the degree of balance of frock will directly affect the measurement of the amount of unbalance of workpiece.
4, the actual use revolution of tool locating benchmark and workpiece datum coincidence.
But existing is all to adopt plain clamp, and positioning precision is low, clamping is inconvenient.
The utility model content
For the problems referred to above, the utility model provides a kind of positioning fixture, to solve the problems of the prior art.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of positioning fixture, it is characterized in that, comprise mandrel component and the two groups of positioning and locking assemblies in order to fixation workpiece that are separately positioned on the mandrel component two ends, described mandrel component comprises mandrel, is arranged on the first female connector and the second female connector in order to withstand the inner hole of workpiece wall on the mandrel cylindrical.
In a preferred embodiment of the present utility model, comprise a conical section on the cylindrical of described the first female connector, wherein one group of positioning and locking assembly comprises the first locking nut and elastic collar, elastic collar is sleeved on outside the first female connector, and for the conical surface, contacts between the cylindrical of the inner surface of elastic collar and the first female connector.
Further, another group positioning and locking assembly comprises the second locking nut and end back-up ring.
In a preferred embodiment of the present utility model, comprise a conical section on the cylindrical of described the second female connector, between the inner hole wall of the second female connector and workpiece, gapless contacts.
In a preferred embodiment of the present utility model, described the first female connector, the second female connector interference fit all and between mandrel.
The utility model can effectively clamp for Internal hole positioning and require the workpiece that positioning precision is high, and positioning precision is high, respond well in actual the use, has met instructions for use.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained and be well understood to.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, further set forth the utility model below in conjunction with specific embodiment.
Referring to Fig. 1, a kind of positioning fixture, comprise mandrel component and the two groups of positioning and locking assemblies in order to fixation workpiece that are separately positioned on the mandrel component two ends.
Mandrel component comprises mandrel 1, be arranged on the first female connector 7 and the second female connector 8 in order to withstand the inner hole of workpiece wall on the cylindrical of mandrel 1.The first female connector 7 and the second female connector 8 interference fit all and between mandrel 1.
Comprise a conical section on the cylindrical of the first female connector 7, the positioning and locking assembly of left end comprises the first locking nut 2 and elastic collar 3, between the cylindrical of the inner surface of elastic collar 3 and the first female connector 7, for the conical surface, contacts.Comprise a conical section (tapering is 1:100) on the cylindrical of the second female connector 8, between the inner hole wall of the second female connector and workpiece, gapless contacts.The positioning and locking assembly of right-hand member comprises the second locking nut 5 and end back-up ring 4.
Operation principle is as follows: during clamping tool part, first the first locking nut 2 is unclamped, make elastic collar 3 in relaxation state.Take away end back-up ring 4 and second locking nut 5 of right side, whole frock is put into to the endoporus of workpiece from the right-hand member of workpiece 6.Make the second female connector 8 contact (the bearing bearing position that contact site is workpiece) with inner hole of workpiece 61, mounting end back-up ring 4, screw the second locking nut 5.Because the cylindrical of the second female connector 8 is a Small Taper body (tapering is 1:100), can guarantee to realize the gapless location of endoporus.Rotate again the first locking nut 2, driving elastic collar 3 moves axially, because the endoporus of elastic collar 3 contacts with the endoporus of the first female connector 7 as conical surface contact, thereby force radially spreading of elastic collar 3, with inner hole of workpiece 62(duty lower bearing bearing position) realize the gapless location.After installing with workpiece, this assembly (comprising workpiece and clamp assembly) is bearing on the roller of balancing machine by the two rapid diameters of axle, drags the external diameter rotation of workpiece with belt, thereby realize the uneven purpose detected.
The utility model can effectively clamp for Internal hole positioning and require the workpiece that positioning precision is high, and positioning precision is high, respond well in actual the use, has met instructions for use.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification, describe is principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
