Description
Technical field
The utility model relates to a kind of centring means, and especially a kind of thin-walled radiation fins centring means belongs to technical field of machining.
Background technology
During for class parts such as batch process gear, ring, sleeves, when the finishing operation, need locate processing excircles and corresponding end face with full endoporus.Prior art generally positions in the following ways:
1, adopts three-jaw back strut endoporus, come the workpiece endoporus is supported the location;
2, punching axle in the endoporus of employing workpiece, the end face nut compresses.
There are some drawbacks in use for above-mentioned the 1st kind of scheme, mainly is easy clamping deformation, for the processing of thin-walled class sleeve part, more is easy to generate distortion especially.For the 2nd kind of scheme, it has solved the clamping deformation problem of workpiece, but owing to use pressing plate, nut end face to compress, so this installation way can only processing excircles, and end face can not be reprocessed.To requiring the ring parts of endoporus, datum level location, and after requiring clamping, can process end face and cylindrical, therefore existing processing locate mode can not satisfy processing request.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of thin-walled radiation fins centring means is provided, and it is simple in structure, easy to install, can process end face and cylindrical by a clamping, improve the stability and the operating efficiency of processing, reduced manufacturing cost, safe and reliable.
According to the technical scheme that the utility model provides, described thin-walled radiation fins centring means comprises mandrel; Be with radiation fins on the described mandrel, an end of described radiation fins utilizes fixed head and mandrel to be fixedly connected, and the other end of radiation fins is provided with pressing plate; Described pressing plate is installed on the mandrel by locking nut, and pressing plate contacts with radiation fins corresponding to the other end that links to each other with locking nut.
On the described radiation fins workpiece is installed, the external diameter of described inner diameter of workpiece and radiation fins is complementary.Described inner diameter of workpiece is greater than the external diameter of pressing plate.
Advantage of the present utility model: an end of radiation fins is fixedly installed on the mandrel by fixed head, and the other end of radiation fins is provided with pressing plate; Workpiece is enclosed within on the radiation fins, and when screwing locking nut, pressing plate can push radiation fins, make radiation fins crimp, make the inwall closely contact mutually of outer wall with the workpiece of radiation fins, thereby reach the fastening purpose that is installed on the mandrel of workpiece, improve the stability of crudy greatly, No. one time clamping is processed end face and cylindrical, and cylindrical need not to connect cutter, the clamping facility, increase work efficiency greatly, the scope of application is wider, and fricton-tight friction, and the life-span is longer; Simple in structure, manufacturing cost is lower.
Description of drawings
Fig. 1 is user mode figure of the present utility model.
Fig. 2 is a force analysis schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As depicted in figs. 1 and 2: the utility model comprises mandrel 1, workpiece 2, radiation fins 3, pressing plate 4, locking nut 5 and fixed head 6.
As shown in Figure 1: be with radiation fins 3 on the described mandrel 1, the axis of the axis of described radiation fins 3 and mandrel 1 is located along the same line; The inwall of radiation fins 3 contacts with the outer wall of mandrel 1.One end of radiation fins 3 is mounted on the mandrel 1 by fixed head 6, and radiation fins 3 is provided with pressing plate 4 corresponding to the other end that links to each other with fixed head 6.Described pressing plate 4 is enclosed within on the mandrel 1, and pressing plate 4 is fastened and connected by locking nut 5 and mandrel 1, and pressing plate 4 contacts with radiation fins 3 corresponding to the other end that links to each other with locking nut 5.
As shown in Figure 1: during use, workpiece 2 is enclosed within on the radiation fins 3, the external diameter of the internal diameter of workpiece 2 and radiation fins 3 is complementary, and the internal diameter of workpiece 2 is greater than the external diameter of pressing plate 4, and the end of pressing plate 4 is stretched in the installing hole of workpiece 2, and contacts with radiation fins 3.For workpiece 2 and radiation fins 3 are fastenedly connected, screw locking nut 5, along with the continuous turn of locking nut 5, locking nut 5 drives constantly extruding radiation fins 3 of pressing plate 4.Because the character of radiation fins 3 crimps as can be known, after radiation fins 3 extrusions, the outer wall of radiation fins 3 closely contacts mutually with the inwall of workpiece 2, thereby workpiece 2 is fixedly installed on the mandrel 1.As shown in Figure 2: for radiation fins 3 be squeezed the distortion after, the schematic diagram of 3 pairs of workpiece 2 of radiation fins and 1 active force of mandrel.After radiation fins 3 distortion, workpiece 2 and mandrel 1 are produced tension force, thereby workpiece 2 can be fixedly mounted on the mandrel 1; Guarantee that workpiece 2 adds man-hour, loosening transfer phenomenon can not occur; And after radiation fins 3 crimps, can not cause workpiece 2 distortion because tension force is excessive, the centering precision height.After the installation, mandrel 1 links to each other with slewing, and process equipment can carry out the manufacturing procedure of needs to workpiece 2.Owing to adopt full endoporus location, workpiece 2 is being added man-hour, cylindrical processing need not tool changing.Workpiece 2 can carry out the processing of end face and cylindrical simultaneously corresponding to the end that links to each other with pressing plate 4.After machining, unclamp locking nut 5, the squeezing action power that pressing plate 4 and radiation fins are 3 disappears, and bellows 3 can reset, and 3 of workpiece 2 and radiation fins keep gap state like this, are convenient to take off the workpiece 2 that machines.
One end of the utility model radiation fins 3 is fixedly installed on the mandrel 1 by fixed head 6, and the other end of radiation fins 3 is provided with pressing plate 4; Workpiece 2 is enclosed within on the radiation fins 3, and when screwing locking nut 5, pressing plate 4 can push radiation fins 3, make radiation fins 3 crimps, make the inwall closely contact mutually of outer wall with the workpiece of radiation fins 3, thereby reach the workpiece 2 fastening purposes that are installed on the mandrel 1, improve the stability of crudy greatly, No. one time clamping is processed end face and cylindrical, and cylindrical need not to connect cutter, the clamping facility, increase work efficiency greatly, the scope of application is wider, and fricton-tight friction, and the life-span is longer; Simple in structure, manufacturing cost is lower.
