Abstract

The utility model relates to a high-precision elastic sleeve clamp which belongs to the technical field of a machine tool clamp. The high-precision elastic sleeve comprises a connecting flange, a cone and an elastic sleeve. The connecting flange is fixedly connected with the cone. The elastic sleeve is in fit connection with the cone through an oblique surface. The upper end surface of the elastic sleeve is provided with a gland which penetrates through the cone and compresses the elastic sleeve. According to the high-precision elastic sleeve clamp, a curved thin-wall integrated type elastic sleeve is adopted. An elastic deformation principle of material is utilized for realizing uniform expansion and centering, and furthermore ensuring use range of the clamp. Furthermore three segments of arc surfaces are reserved on the elastic sleeve for minimizing effect of positioning surface deformation of an element, thereby ensuring high precision of a machined product.

Description

A kind of high precision elastic sleeve clamp
Technical field
The utility model belongs to jig technical field, relates to a kind of elasticity shell type fixture, refers in particular to a kind of high precision elastic sleeve clamp.
Background technology
Existing this type of part clamp has following several structure: 1 collet-type, 2 bonded resilient sleeve, 3 oblique Xie formula resilient sleeve.Above structure has the following disadvantages: 1, collet chuck, oblique not easy to clean etc. of poor, the smear metal of Xie formula precision stability, and high to product orientation surface requirements; 2, bonded complex process and be not suitable for the occasions such as high temperature, cold oil high flow rate, and processing parts after heat treatment surfaces externally and internally all occur being to a certain degree out of shape, while overlapping by traditional elastic, easily occur that location is interfered and processing after springback influence precision.
Utility model content
The purpose of this utility model is to overcome the deficiency existing in background technology, proposes the high precision elastic sleeve clamp that the high and applicable high temperature of a kind of clamp precision, cold oil high speed situation carry out work.
For achieving the above object, the utility model adopts following scheme:
A kind of high precision elastic sleeve clamp, comprises adpting flange, cone and resilient sleeve, and described adpting flange is fixedly connected with cone, and described resilient sleeve and cone are connected by inclined-plane, and resilient sleeve upper surface is provided with the gland that runs through cone and compress resilient sleeve.
In above-mentioned a kind of high precision elastic sleeve clamp, described resilient sleeve is by a conical ring as resilient sleeve matrix, and circumference uniform distribution is processed at least three sections of curvilinear elastic walls.
In above-mentioned a kind of high precision elastic sleeve clamp, described gland lower end is provided with the power set that pull gland.
In above-mentioned a kind of high precision elastic sleeve clamp, described power set are oil cylinder or cylinder, and the piston rod of oil cylinder or cylinder is fixedly connected with gland.
In above-mentioned a kind of high precision elastic sleeve clamp, described adpting flange upper end is also provided with a gripper shoe, and cone runs through gripper shoe.
In above-mentioned a kind of high precision elastic sleeve clamp, on described adpting flange, be provided with an alignment pin, in described resilient sleeve, be provided with a location blind hole coordinating with alignment pin.
In above-mentioned a kind of high precision elastic sleeve clamp, between described piston rod and resilient sleeve, be provided with a back-moving spring.
The utility model beneficial effect is compared to existing technology: the utility model adopts curve thin-walled monolithic resilient sleeve, utilizes elastic properties of materials deformation principle, realizes the centering that evenly swells, and then has guaranteed the scope of application of fixture; And resilient sleeve retains three sections of cambered surfaces the impact of part locating surface distortion is reduced to minimum, thereby guarantees the precision of the rear product of processing.
Accompanying drawing explanation
Fig. 1 is the cutaway view of a kind of high precision elastic sleeve clamp of the utility model.
Fig. 2 is the top view of a kind of high precision elastic sleeve clamp of the utility model resilient sleeve
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
A kind of high precision elastic sleeve clamp as shown in Figure 1, comprise adpting flange 2, cone 3 and resilient sleeve 5, described adpting flange 2 is fixedly connected with cone 3, described resilient sleeve 5 and cone 3 are connected by inclined-plane, and resilient sleeve 5 upper surfaces are provided with the gland 6 that runs through cone 3 and compress resilient sleeve 5.In work, by resilient sleeve 5 holding workpieces 8, utilize the strain of resilient sleeve 8, realize the working environment that evenly swells and feel relieved and then adapt to its high temperature or low temperature.
In above-mentioned, in order to guarantee clamp precision, described resilient sleeve 5 by a conical ring as resilient sleeve matrix, three sections of curve-like elastic walls of circumference uniform distribution processing, conical ring does not need to cut open, rely on realization under the arc effect of three sections of elastic walls evenly to swell, be distorted distortion and contact the phenomenons such as inhomogeneous of the Shi Buhui that swells.
In above-mentioned, described gland 6 lower ends are provided with the power set 1 that pull gland 6, and in order to guarantee the precision of its location, described power set are oil cylinder or cylinder, and the piston rod 10 of oil cylinder or cylinder is fixedly connected with gland 6.
In above-mentioned, in order to guarantee the precise positioning of workpiece, described adpting flange 2 upper ends are also provided with a gripper shoe 4, and cone 3 runs through gripper shoe 4.
In above-mentioned, in order to guarantee that resilient sleeve 5 is not glanded 6 excessive extrusion, on described adpting flange 2, be provided with an alignment pin 7, in described resilient sleeve 5, be provided with a location blind hole coordinating with alignment pin 7.
In above-mentioned, between described piston rod 10 and resilient sleeve 5, be provided with a back-moving spring 9.When power set 1 pass through piston rod tension and compression lid 6, its back-moving spring 9 produces and draws high distortion, when power set are not worked, by its back-moving spring 9, piston rod 10 and gland 6 is resetted.
Resilient sleeve 5 adopts curve thin-walled monolithic resilient sleeve, utilizes elastic properties of materials deformation principle, realizes the centering that evenly swells; Resilient sleeve 5 retains three sections of cambered surfaces the impact of locating surface distortion is reduced to minimum, thereby guarantees the clamp precision of workpiece 8.
The foregoing is only preferred embodiment of the present utility model; not take the present embodiment as restriction; all any modifications of making within spirit of the present utility model and principle, be equal to and replace or improvement etc., within all should being included in protection domain of the present utility model.
