Abstract
The invention relates to a shaft type workpiece holder used for clamping of a shaft type workpiece. The shaft type workpiece holder comprises a mounting disc, and positioning V-shaped blocks and a holding device that are arranged on the mounting disc, wherein the mounting disc is provided with a guide groove A and a guide groove B along the diameter direction of the mounting disc; the guide groove A and the guide groove B are mutually perpendicular; the cross sections of the guide groove A and the guide groove B are inverted-T-shaped; the number of the positioning V-shaped blocks is two; the positioning V-shaped blocks are symmetrically arranged on the mounting disc along the extension direction of the guide groove A; center lines of the two positioning V-shaped blocks are coincided with that of the guide groove A; the holding device is arranged on the mounting disc; the center line of the holding device is coincided with the center line of the guide groove B; and the holding device comprises a supporting block, a pressure plate and a locking bolt. The shaft type workpiece holder has the advantages that the shaft type workpiece is positioned by the two positioning V-shaped blocks, and is held by the holding device, thereby realizing the clamping of the shaft type workpiece; the clamping is more secure; the possibility of rotation is low; and the machining precision is higher.
Description
Technical field
The present invention relates to a kind of work piece holder, particularly a kind of shaft-like workpiece fixture.
Background technology
In workpiece process, need to be fixedly clamped to workpiece, to guarantee the stability in workpiece process, and can Workpiece Machining Accuracy be improved, generally supportingly can have multiple fixing chuck or stationary fixture in work pieces process.
And in the process of shaft-like workpiece, because its forming surface is arc shaped surface, traditional fixing chuck or stationary fixture cannot realize the stable clamping for shaft-like workpiece, thus cause in process because clamping is not fastening, the problems such as workpiece rotates, have a strong impact on the machining accuracy of workpiece.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and is adapted to shaft-like workpiece and is fixedly clamped, and the more firm fixture of clamping.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of shaft-like workpiece fixture, for the clamping of shaft-like workpiece, its innovative point is: comprise and install disk, be arranged at and install positioning V-shaped block on disk and clamping device, described installation disk has two orthogonal gathering sill A and gathering sill B along its diametric(al), and the cross section of this gathering sill A and gathering sill B is inverted T shape;
Described positioning V-shaped block is a pair, be symmetricly set in and install on disk, and the center line of two positioning V-shaped blocks and gathering sill A center line coincides along gathering sill A bearing of trend; This positioning V-shaped block lower end is provided with a slide block A matched with gathering sill A, and can be slidably matched with installation disk;
Described clamping device is arranged to be installed on disk, its center line and gathering sill B center line coincide, comprise back-up block, pressing plate and clamping screw, stepped being arranged at of described back-up block is installed on disk, this back-up block presents the supporting surface be parallel to each other, its lower end is provided with a slide block B matched with gathering sill B, and can be slidably matched with installation disk, described pressing plate is horizontally disposed with, a waist type regulating tank matched with clamping screw is had in the middle part of it, and the locking of pressing plate is realized by clamping screw, this clamping screw lower end is installed in gathering sill B and also can realizes being slidably matched with installation disk.
Further, the distance on described back-up block between each supporting surface is equal.
The invention has the advantages that:
(1) realize the location to shaft-like workpiece by two positioning V-shaped blocks, and realize the clamping to shaft-like workpiece by clamping device, thus realize the clamping of shaft-like workpiece, the more fastening phenomenon not easily rotated of clamping, makes machining accuracy higher.
(2) each supporting surface on back-up block equidistantly distributes, and when the shaft-like workpiece that replacing diameter is different, is convenient to the upper-lower position regulating pressing plate, more practical.

Fig. 2 is the top view of a kind of shaft-like workpiece fixture of the present invention.
Fig. 3 is the left view of a kind of shaft-like workpiece fixture of the present invention.
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, the invention discloses a kind of shaft-like workpiece fixture, comprise and disk 1 is installed, is arranged at and positioning V-shaped block 2 on disk 1 and clamping device are installed, install disk 1 and have two orthogonal gathering sill A11 and gathering sill B12 along its diametric(al), the cross section of this gathering sill A11 and gathering sill B12 is inverted T shape.
Positioning V-shaped block 2 is a pair, be symmetricly set in and install on disk 1, and the center line of two positioning V-shaped blocks 2 and gathering sill A11 center line coincides along gathering sill A11 bearing of trend; This positioning V-shaped block 2 lower end is provided with a slide block A21 matched with gathering sill A11, and can be slidably matched with installation disk 1.
Clamping device is arranged to be installed on disk 1, its center line and gathering sill B12 center line coincide, comprise back-up block 3, pressing plate 4 and clamping screw 5, stepped being arranged at of back-up block 3 is installed on disk 1, this back-up block 3 presents the supporting surface 31 be parallel to each other, and distance between each supporting surface 31 is equal, its lower end is provided with a slide block B matched with gathering sill B12, and can be slidably matched with installation disk 1, pressing plate 4 is horizontally disposed with, a waist type regulating tank 41 matched with clamping screw 5 is had in the middle part of it, and the locking operation of pressing plate 4 is realized by clamping screw 5, this clamping screw 5 lower end is installed in gathering sill B12 and also can realizes being slidably matched with installation disk 1.
During use, adjust the position of two positioning V-shaped blocks 2, shaft-like workpiece 6 is put on two positioning V-shaped blocks 2, realize the location to shaft-like workpiece 6, then the position of back-up block 3 is adjusted, pressing plate 4 one end is put on the supporting surface 31 of back-up block 3, the other end puts the upper end to shaft-like workpiece 6, and clamping screw 5 top nut 51 is screwed the compression operation realizing pressing plate 4, when carrying out clamping to the shaft-like workpiece 6 of different-diameter and different length, by adjusting the position of two positioning V-shaped blocks 2, and regulate the position of rest pad 3, pressing plate 4 is placed on suitable supporting surface 31, tighten the nut 51 on clamping screw 5.
