Utility model content
The technical problem to be solved by the present invention is to provide a kind of flexible positioning pin, which will not position mistake
It loses, equipment and workpiece will not damage.
To solve the above problems, the following technical schemes are provided:
A kind of flexible positioning pin of the utility model includes support tube, and the nozzle of the support tube is upward, concentric in support tube
It is provided with positioning pin rod, in sliding shape cooperation, the lower end of positioning pin rod and the cylinder of support tube between positioning pin rod and support tube inner wall
There is compressed spring between bottom.Have through-hole on the support tube side wall of the positioning pin rod side, there is positioning column in the through-hole, positioning column with
In sliding shape cooperation between through-hole.There is upper limit hole on the corresponding positioning pin rod side wall of the positioning column.Its main feature is that the upper limit
There is lower limit hole on positioning pin rod side wall below the hole of position.
Wherein, there is a limiting slot being vertically arranged in the positioning pin rod side of remotely located column, in the corresponding support tube of limiting slot
Wall upper screwed hole has stop screw in threaded hole, and the head of screw is located in limiting slot, and in sliding between stop screw and limiting slot
Dynamic shape cooperation, when positioning pin rod reaches under outer limiting condition along support tube, the lower part of stop screw and limiting slot, positioning column with
The position in lower limit hole is corresponding, and compressed spring is under relaxation state, when positioning pin rod extend into interior limiting condition along support tube
Under, the top of stop screw and limiting slot, positioning column is corresponding with the position in upper limit hole, and compressed spring is under compressive state.
The top of the support drum outer wall is connected with annular outer platform, and institute's through-hole and threaded hole are out of support tube
Wall is through on the lateral surface of annular outer platform.
Positioning column one end of remotely located pin rod reaches outside support tube from through-hole, and has drawing on the overhanging end of positioning column
Ring.
Gasket and retaining ring are disposed between the compressed spring bottom and the cylinder bottom of support tube.
The above scheme has the following advantages:
Due to having lower limit hole on the positioning pin rod side wall below the upper limit hole of the flexible positioning pin of invention, flexible fixed
Under overhanging state, positioning column is located in lower limit hole position pin.When placing workpiece, when workpiece can be pressed onto positioning pin rod, by
In positioning column and lower limit hole position-limiting action, positioning pin rod will not be retracted into support tube, so as to avoid showing for positioning failure
As so that equipment and workpiece damage due to will not being not allowed because positioning.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the flexible positioning pin of the utility model (under positioning pin rod contraction state)；
Fig. 2 is the structural schematic diagram of the positioning pin rod of the flexible positioning pin of the utility model in the extended state.
Specific embodiment
The utility model is described in further details below in conjunction with attached drawing.
As shown in Figure 1, a kind of flexible positioning pin of the utility model includes support tube 1, the nozzle of the support tube 1 upward,
It has been arranged concentrically positioning pin rod 2 in support tube 1, has cooperated between 1 inner wall of positioning pin rod 2 and support tube in sliding shape, positioning pin rod 2
There is compressed spring 9 between lower end and the cylinder bottom of support tube 1.There is through-hole on 1 side wall of support tube of 2 side of positioning pin rod, this is logical
There is positioning column 11 in hole, in sliding shape cooperation between positioning column 11 and through-hole.On corresponding 2 side wall of positioning pin rod of the positioning column 11
There is upper limit hole 3.There is lower limit hole 10 on 2 side wall of positioning pin rod of 3 lower section of upper limit hole.
There is a limiting slot 6 being vertically arranged in 2 side of positioning pin rod of remotely located column 11, in the corresponding support tube 1 of limiting slot 6
Wall upper screwed hole has stop screw 4 in threaded hole, and the head of screw is located in limiting slot 6, and between stop screw 4 and limiting slot 6
In sliding shape cooperation, when positioning pin rod 2 reaches under outer limiting condition along support tube 1, the lower part of stop screw 4 and limiting slot 6,
Positioning column 11 is corresponding with the position in lower limit hole 10, and compressed spring 9 is under relaxation state, when positioning pin rod 2 is stretched along support tube 1
Enter under interior limiting condition, the top of stop screw 4 and limiting slot 6, positioning column 11 is corresponding with the position in upper limit hole 3, compression
Spring 9 is under compressive state.
In order to increase intensity, the top of 1 outer wall of support tube is connected with annular outer platform 5, institute's through-hole and screw thread
The inner wall of Kong Juncong support tube 1 is through on the lateral surface of annular outer platform 5.
For the ease of adjustment, 11 one end of positioning column of remotely located pin rod 2 is and fixed from being reached outside support tube 1 in through-hole
