Cause assembling product unstable.Therefore, it is necessary to a kind of devices that can solve the above problem.
Summary of the invention
In order to overcome shortcoming and defect existing in the prior art, the purpose of this utility model is to provide a kind of adaptive
Flexibly positioned pin mechanism.
To achieve the above object, the utility model uses following scheme.
A kind of adaptive flexibly positioned pin mechanism, including dowel body, tight lock section, positioning head and bulb plunger；Institute
Tight lock section is stated set on dowel body bottom end, the positioning head is set to dowel body top；The diameter of the dowel body
It is equipped with plunger channel upwards, the bulb plunger is inserted in plunger channel；The bulb plunger is equipped with contact head and compression bullet
Spring, the contact head are set to one end of bulb plunger, and the compressed spring is set to inside bulb plunger, and compressed spring both ends point
It is not supported with the bottom surface of bulb plunger and contact head；The positioning head is equipped with placed channel, is equipped with spiral shell without a head in placed channel
Silk, the grub screw are supported with bulb plunger.
Further, the tight lock section bottom end is equipped with tight lock access, and tight lock screw is equipped in tight lock access.
Further, the positioning head is round table-like.
Further, the bulb plunger bottom end is equipped with the spring extrusion block being flexibly connected, the spring extrusion block and bullet
Spring is supported.
Further, the contact head is hemispherical or arc-shaped.
The utility model has the beneficial effects that a kind of adaptive flexibly positioned pin mechanism is provided, by radially setting in positioning pin
Bulb plunger makes positioning pin be close to product orientation hole inner edge, effectively avoids product from falling off positioning pin, greatly improves assembling product
Stability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
For the ease of the understanding of those skilled in the art, the utility model is made below with reference to examples and drawings further
Explanation, the content that embodiment refers to not is restriction to the utility model.
A kind of adaptive flexibly positioned pin mechanism, including dowel body 1, tight lock section 2, positioning head 3 and bulb plunger
4；The tight lock section 2 is set to 1 bottom end of dowel body, and the positioning head 3 is set to 1 top of dowel body；The positioning pin
Ontology 1 is radially equipped with plunger channel, and the bulb plunger 4 is inserted in plunger channel；The bulb plunger 4 is equipped with contact
First 7 and compressed spring 6, the contact head 7 is set to one end of bulb plunger 4, and the compressed spring 6 is set to inside bulb plunger 4,
And 6 both ends of compressed spring are supported with the bottom surface of bulb plunger 4 and contact head 7 respectively；The positioning head 3 is equipped with placed channel,
Grub screw 5 is equipped in placed channel, the grub screw 5 is supported with bulb plunger 4.
Dowel mechanism is rigidly fastened on jig plate in use, first passing through tight lock section 2, adjusting ball head plunger 4 is logical in plunger
Position in road, and allow bulb plunger 4 contact head 7 stretch out plunger channel, followed by grub screw 5 to bulb plunger 4 into
Row is pressed closer to fix the position of bulb plunger 4, product orientation hole alignment positioning pin is packed into product, contact head 7 is by fixed at this time
The pressure back shrinkage of position hole inner edge simultaneously compresses the compressed spring 6 in bulb plunger 4, and after product is completed to be packed into, contact head 7 exists
Restore origin-location and tightly to support location hole inner edge under the action of compressed spring 6, product effectively avoided to fall off positioning pin with this,
Greatly improve the stability of assembling product.
In the present embodiment, tight 2 bottom end of lock section is equipped with tight lock access, and tight lock screw 8 is equipped in tight lock access.It will positioning
Pin is placed on jig plate, and positioning pin is fastened securely on jig plate by tight screw 8 of locking using the location hole on jig plate.
