Abstract
The utility model cam-type Jia Zhi mechanism, comprises base, described base offers the chute of two levels, slidably connects slide block in described chute, and described slide block is fixed with a vertical folder and refers to, described folder refers to be provided with arc chuck; Described base is also provided with the cam that is positioned at vertical plane, described cam is between two slide blocks, and described cam, slide block and folder refer to be positioned at same plane, described in two folders be fixed on slide block refer to be provided with stage clip.Refer to that fixing arc chuck forms the clamping part of clamping spherical work-piece at folder.Stage clip is for clamping spherical work-piece, unclamping of spherical work-piece, is to rely on the cam between two slide blocks to realize.By rotating cam, promote slide block and move, thus on band movable slider, fixing folder refers to mobile.When increase folder refers to spacing, play the effect of unclamping spherical work-piece.
Description
Technical field
The utility model relates to a kind of clamping tool for machine work, is specifically related to a kind of cam-type Jia Zhi mechanism.
Background technology
Fixture adds to be used for rapid fastenings man-hour, makes lathe, cutter, part keep the process unit of correct relative position.Frock clamp is the indispensable parts of machining, machine tool technology at a high speed, efficient, precision, compound, intelligence, environmental protection future development drive under, clamp technology is just towards high-precision, efficient, module, combination, general, economic future development.Jig, is conducive to the machining accuracy, the stabilized product quality that ensure part; Be conducive to raising labour productivity and reducing costs; Be conducive to improving workman's working condition, ensure safety in production; Be conducive to enlarger bed process scope, realize " a tractor serves several purposes ".Fixture is usually by compositions such as setting element (determining the tram of part in fixture), clamping device, tool setting induction element (determine the relative position of cutter and part or guide tool orientation), indexing means (make part can complete the processing of several station in once mounting, have circular index device and rectilinear movement indexing means two class), Connection Element and clamp bodies (clamp base).At present, when processing spherical work-piece, needing to position spherical work-piece and clamp, could process it afterwards.Current processing clamping, majority is difficult to effectively clamp spherical work-piece, moreover chucking power is excessive, is easy to the spherical work-piece damaging lighter weight, cannot reaches the object of effectively processing.
Utility model content
The purpose of this utility model is to provide a kind of cam-type Jia Zhi mechanism, by simple structural design, realizes the effective clamping to lightweight spherical work-piece.
For achieving the above object, the technical solution of the utility model is: cam-type Jia Zhi mechanism, comprises base, described base offers the chute of two levels, slidably connect slide block in described chute, described slide block is fixed with a vertical folder and refers to, described folder refers to be provided with arc chuck; Described base is also provided with the cam that is positioned at vertical plane, described cam is between two slide blocks, and described cam, slide block and folder refer to be positioned at same plane, described in two folders be fixed on slide block refer to be provided with stage clip.
When adopting technique scheme, refer to that fixing arc chuck forms the clamping part of clamping spherical work-piece at folder.Stage clip is for clamping spherical work-piece, unclamping of spherical work-piece, is to rely on the cam between two slide blocks to realize.By rotating cam, promote slide block and move, thus on band movable slider, fixing folder refers to mobile.When increase folder refers to spacing, play the effect of unclamping spherical work-piece.Mechanism is active in one's movements, and can unclamp fast and clamp spherical work-piece, and can carry out, for fine setting, solving actual processing problems to the size of the position of clamping and clamping force.
Further, described slide block is provided with roller, the Hp contacts of described roller and cam.This setting by roller and cam contact, can change sliding friction pair into rolling friction, reduces wearing and tearing.
Further, the shape of described cam is oval.
Further, the cross sectional shape of described slide block is rectangle, and the cross sectional shape of described chute is also rectangle.This setting, can roll by anti-limited slip block in chute, makes the precision of location and clamping higher.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation that the utility model cam-type folder refers to mechanism embodiment.
Detailed description of the invention
As shown in Figure 1, the utility model cam-type Jia Zhi mechanism, comprises base 1, base 1 offers the chute of two levels, slidably connects slide block 2 in chute, and slide block 2 is fixed with a vertical folder and refers to 3, folder refers to that 3 are provided with arc chuck 4; Slide block 2 is provided with roller 21, the Hp contacts of roller 21 and cam 5.This setting can be contacted with cam 5 by roller 21, changes sliding friction pair into rolling friction, reduces wearing and tearing.Base 1 is also provided with the cam 5 that is positioned at vertical plane, the shape of cam 5 is oval.Cam 5 is between two slide blocks 2, and cam 5, slide block 2 and folder refer to that 3 are positioned at same plane, and two folders be fixed on slide block 2 refer to that 3 are provided with stage clip 6.The cross sectional shape of slide block 2 is rectangle, and the cross sectional shape of chute is also rectangle.This setting, can roll by anti-limited slip block 2 in chute, makes the precision of location and clamping higher.
When adopting technique scheme, refer to that arc chuck 4 fixing on 3 forms the clamping part of clamping spherical work-piece 7 at folder.Stage clip 6 is for clamping spherical work-piece 7, unclamping of spherical work-piece 7, is to rely on the cam 5 between two slide blocks 2 to realize.By rotating cam 5, promote slide block 2 and move, thus on band movable slider 2, fixing folder refers to that 3 move.When increase folder refers to the spacing of 3, play the effect of unclamping spherical work-piece 7.Mechanism is active in one's movements, and can unclamp fast and clamp spherical work-piece 7, and can carry out, for fine setting, solving actual processing problems to the size of the position of clamping and clamping force.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; without departing from the concept of the premise utility; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
