Abstract
The utility model belongs to the technical field of mechanical processing, and discloses a clamping tool capable of automatically and precisely centering through fine adjustment. The clamping tool comprises an elastic sleeve (1), a locking piece (2) and a locking ring nut (3), wherein the elastic sleeve (1) and the locking piece (2) are in conical surface fit, and are connected with the locking ring nut (3) as a whole through the locking of the locking ring nut (3). The clamping tool enables the elastic sleeve to be evenly deformed in all directions through evenly distributing opened rectangular grooves staggered in two directions on the elastic sleeve, so that the clamping tool can adapt to the fine adjustment function of the shapes of free dimensional tolerance workpieces.
Description
Technical field
The utility model belongs to Machining Technology field, is also applicable to the technical fields such as welding, assembling, relates to a kind of location clamping tool, particularly a kind of clamping tool of fine-tuning automatic precision centering.
Background technology
In order to realize some property, space product has adopted many large thin wall rotating body aluminium alloy cylindrical body members in structural design.For this class A of geometric unitA, can adopt foundry goods, by machining process, realize.Tradition space product is very strict for the requirement of this type of structural member dimensional accuracy, and for the axiality of interior (outward) seam at simplified two ends and two ends end face, internally the requirement of the perpendicularity of (outward) seam is very high mutually conventionally.This class large thin wall rotating body stiffness of structural member is low, and in mechanical processing process, Deformation control difficulty is very large.Tradition processing cylinder inboard wall frock adopts chuck, stifled dish, pull bar and the structure combination such as top, must have positioning datum and accurate location dimension.And the common appearance and size precision of simplified member in space product is not strict with, mostly be free tolerance, be difficult to, as accurate positioning datum, with said method, cannot realize precision centering.From the viewpoint of economy, in technique, improve the mode of appearance and size precision also improper.Therefore, must design a kind of be adapted to the simplified member free size of thin wall rotating body aluminium alloy tolerance profile can automatic pinpoint frock.
Summary of the invention
The technical solution of the utility model is that the large thin wall rotating body aluminium alloy cylindrical body member existing in prior art is yielding in mechanical processing process in order to overcome, cylindrical shell appearance and size precision is low cannot be as shortcomings such as accurate positioning datums, provide a kind of can not only be at the clamping tool of the distortion of machining Whole Process Control and fine-tuning automatic precision centering.
The technical solution of the utility model:
A clamping tool for fine-tuning automatic precision centering, this frock comprises resilient sleeve (1), locking member (2), retainer nut (3).Said resilient sleeve (1) is connected three with locking member (2) cone match and by retainer nut (3) locking.Said resilient sleeve (1) inner surface is the face of cylinder, and during work and workpiece close contact, resilient sleeve (1) outer surface is the conical surface, the rectangular channel of an end opening of uniform two-way cross on the conical surface.Said locking member (2) inner surface is the conical surface, coordinates with the male cone (strobilus masculinus) of resilient sleeve (1), and locking member (2) outer surface one end is the screw thread of metric system closely-pitched.Said retainer nut (3) one end is the internal thread of metric system closely-pitched, screw with locking member (2) external screw thread, by worm drive, make retainer nut (3) inner face be close to locking member (2) end face, locking member (2) and resilient sleeve (1) are relatively moved, and after resilient sleeve (1) is subject to locking member (2) extruding homogeneous deformation, workpiece is held in self-centering tightly.
The beneficial effects of the utility model:
The utility model puts the structure of the opening rectangular channel of uniform two-way cross by design flexibility, make the resilient sleeve can homogeneous deformation in each orientation, has realized the fine-tuning function that frock can be adapted to free size tolerance workpiece profile; By design flexibility overlap and locking member between tapered face fit structure and the resilient sleeve structure that realizes homogeneous deformation, realized the frock function of precision centering automatically; By design retainer nut and locking member screw thread, screw locking mechanism, not only realized the function of the firm clamping work pieces of frock, can also in machining overall process, effectively control the distortion of workpiece.Therefore, the present invention not only efficiently solves the control problem that the simplified member of large thin wall rotating body aluminium alloy is out of shape in mechanical processing process, and has realized and be adapted to the precision centering automatically of thin wall rotating body aluminium alloy cylindrical body member free size tolerance profile and the function of clamping.

Label: resilient sleeve (1), locking member (2), retainer nut (3)
The specific embodiment
Fig. 1 is the utility model general structure schematic diagram, and as shown in Figure 1, this frock comprises resilient sleeve (1), locking member (2), retainer nut (3).Said resilient sleeve (1) is connected three with locking member (2) cone match and by retainer nut (3) locking.Said resilient sleeve (1) inner surface is the face of cylinder, and during work and workpiece close contact, resilient sleeve (1) outer surface is the conical surface, the rectangular channel of an end opening of uniform two-way cross on the conical surface.Said locking member (2) inner surface is the conical surface, coordinates with the male cone (strobilus masculinus) of resilient sleeve (1), and locking member (2) outer surface one end is the screw thread of metric system closely-pitched.Said retainer nut (3) one end is the internal thread of metric system closely-pitched, screw with locking member (2) external screw thread, by worm drive, make retainer nut (3) inner face be close to locking member (2) end face, locking member (2) and resilient sleeve (1) are relatively moved, and after resilient sleeve (1) is subject to locking member (2) extruding homogeneous deformation, workpiece is held in self-centering tightly.
