Technical Field
The utility model relates to a frock clamp concrete technical field, concretely relates to locating pin mistake proofing structure floats.
Background
In the machining process, a workpiece blank hole is usually used as a positioning hole, a floating positioning pin is arranged on a clamp body for positioning (as shown in figure 1), an airtight hole is arranged on the clamp body, and whether the workpiece is accurately positioned or not is judged through airtight detection. The work piece can appear placing the condition not in place when the installation, and the work piece can push down the locating pin this moment, and locating pin compression spring, work piece still can seal airtight hole, and airtight detection is equivalent to failure state this moment, consequently has the erroneous judgement phenomenon to whether correctly placing the work piece, therefore can cause the work piece processing to scrap.
Disclosure of Invention
To the technical problem that exists at present, the utility model provides a locating pin mistake proofing structure floats to solve the problem among the prior art.
In order to achieve the purpose of the invention, the utility model provides the following technical scheme:
the utility model provides a floating positioning pin mistake proofing structure, includes the anchor clamps body, establishes the mounting hole on this anchor clamps body, and the unsteady locating pin that is equipped with in this mounting hole, this locating pin lower extreme coupling spring, the one end butt of this spring is in the lower extreme of locating pin, its other end butt is on the end fixing base, be equipped with spacing post in the mounting hole, the lower extreme of this spacing post with the end fixing base links to each other, the spring housing is on this spacing post, and works as when the lower extreme of locating pin contacts with spacing post, the upper end of this locating pin stretches out the mounting hole, be equipped with the gas tight hole on the anchor clamps body.
Above-mentioned technical scheme, if the work piece is not placed in place in the use, then the locating pin can support and press the spring, and the locating pin moves down after the spring compression, stops moving down after the contact of locating pin lower extreme spacing post, and spacing post is with locating pin jack-up, the upper end of locating pin stretches out the mounting hole this moment, and the airtight hole on the anchor clamps body can not the shutoff, and airtight detection is inefficacy to this judges that the work piece installation is not in place, reaches the mistake proofing effect, avoids adding the emergence and hits the sword accident.
Preferably, an internal thread section is arranged in the mounting hole and close to the lower end of the mounting hole, and the end fixing seat is connected to the internal thread section of the mounting hole through an external thread.
Preferably, the mounting hole is a stepped hole, the lower end part of the positioning pin, the limiting column and the spring are located in the large-aperture section of the stepped hole, the diameter of the lower end part of the positioning pin is larger than that of the positioning pin body, and the lower end part of the positioning pin can abut against a step in the mounting hole in the floating process of the positioning pin.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a set up spacing post and restrict the unsteady stroke of locating pin, spacing post can be with locating pin and work piece jack-up when the work piece can not place the position, and airtight hole on the anchor clamps body is not by the shutoff, and airtight detection is inefficacy to reach the mistake proofing effect, avoid adding the emergence and hit the sword accident man-hour, reduce the loss, and overall structure is simple, and the result of use is better.
