Abstract
The utility model provides a self-centering locating mechanism, which is characterized in that the locating mechanism comprises a base; stepped holes are formed on the base; a locating rod consisting of a pull rod and a locating block is installed in the holes; the pull rod extends out from the base; a spring is installed between the back surface of the locating block and the base; two pin holes are formed on the pull rod; and the locating surface of the locating block is saw-shaped . The locating mechanism has the advantages of simple structure, convenient clamping and good self-centering property.
Description
Technical field
The utility model relates to a kind of detent mechanism, particularly relates to a kind of self-centering detent mechanism.
Background technology
The workpiece that present clamping both ends of the surface are the plane generally adopts bench vice, the clamping trouble, and do not have the self-centering function.
Summary of the invention
Bother in order to overcome existing flat work pieces clamping, the deficiency of self-centering difference, the utility model provides a kind of detent mechanism.
The technical scheme that its technical problem that solves the utility model adopts is a kind of self-centering detent mechanism, comprise pedestal, have shoulder hole on the pedestal, backstay is housed in the hole, backstay is made up of pull bar and locating piece, pull bar stretches out pedestal, and spring also is housed between the back side of locating piece and the pedestal, has 2 pin-and-holes on pull bar.
The locating surface of locating piece is a zigzag.
The beneficial effects of the utility model are simple in structure, convenient mounting and clamping, and the self-centering performance is good.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural map of present embodiment;
Among the figure: 1. pedestal; 2. stepped hole; 3. pull bar; 4. pin-and-hole; 5. latch; 6. backstay; 7. locating piece; 8. spring.
The specific embodiment
As shown in Figure 1, a kind of self-centering detent mechanism, comprise pedestal 1, have shoulder hole 2 on the pedestal 1, backstay 6 is housed in the shoulder hole 2, backstay 6 is made up of pull bar 3 and locating piece 7, pull bar 3 stretches out pedestal 1, between the back side of locating piece 7 and the pedestal 1 spring 8 is housed also, has 2 pin-and-holes 4 on pull bar 3, the locating surface of locating piece 7 is a zigzag.
During clamping, the self-centering detent mechanism uses in pairs, and in the pin-and-hole 4 of latch 5 insertions away from locating piece 7, locating piece 7 is close to surface of the work all the time under the effect of spring 8, because two detent mechanism symmetric arrangement, thereby the self-centering of the work of realization.After the workpiece completion of processing, pull bar 3 toward post-tensioning, is exposed the pin-and-hole 4 near locating piece 7, latch 5 is inserted, backstay 6 is thrown off workpiece and locking.
