Abstract
The invention relates to a clamp, in particular to an elastic deformation locating pin. The elastic deformation locating pin comprises a pin body, a steel ball, a spring and a Kimi screw, and is characterized in that the pin body is composed of a pin base, a pin main body and a pin head, a spring hole is formed in the pin body, the axis of the spring hole is overlapped with the axis of the pin body, the upper end of the spring hole is arranged at the position where the pin main body is connected with the pin head and is at a 45-degree taper angle, sealing and plugging threads are arranged at the lower end of the spring hole, at least two deformation grooves are formed in the pin head, the pin head is equally divided through the deformation grooves in the radial direction, the lower ends of the deformation grooves are communicated with the top end of the spring hole, the steel ball and the spring are arranged inside the spring hole and located through the Kimi screw, the steel ball is in 45-degree-conical-surface contact with the top end of the spring hole in an abutting-against mode, the spring is arranged below the steel ball, and the Kimi screw is arranged below the spring. When the elastic deformation locating pin works, the locating pin is in large-amount interference fit with an inner hole of a product, and as the steel ball is in 45-degree-angle contact with the conical surface, large self-locking force can not be generated; the tension force of the locating pin can be conveniently adjusted by adjusting the vertical position of the Kimi screw, and the elastic deformation locating pin has the advantages of being easy to operate and safe in use, due to adjustment on the stress relation, the clamping force can be transmitted to the spring, and abrasions to the locating pin are effectively reduced.
Description
Technical field
The present invention relates to a kind of fixture, specifically a kind of easy to operate, reliable operation, the elastic deformation of stable performance
Alignment pin.
Background technology
It is known that needing a lot of alignment pins in diverter assembly line work, these alignment pins must possess preferably
Elasticity, can not to have relative motion when product is placed in above it, just can play good positioning action.Particularly pressure
Test this part, often because pin causes pin elastic deformation to disappear due to long term wear, leads to product orientation to be forbidden and go out
Now judge by accident.
Content of the invention
The purpose of the present invention is exactly to overcome prior art, provide a kind of easy to operate, reliable operation, stable performance,
Realize the elastic deformation alignment pin of a tractor serves several purposes.
The present invention solves above-mentioned technical problem and employed technical scheme comprise that:
A kind of elastic deformation alignment pin, including shank, steel ball, spring and base rice screw it is characterised in that shank is by pin
Seat, pin body and plunger composition, are provided with the spring eye of axis and shank dead in line in shank, the upper end of spring eye be located at pin body with
Plunger junction be in 45 degree cone angles, the lower end of spring eye is provided with blocking screw thread, at least provided with two deformation grooves in plunger, deforms
Plunger in radial direction decile, is deformed groove lower end and is connected with spring eye top, spring in the hole is provided with steel ball and spring and through base by groove
Rice screw positioning, steel ball and spring eye top are in that 45 degree of conical surfaces are conflicted, and steel ball is presented herein below spring, and spring is presented herein below base rice screw,
During work, alignment pin and product endoporus have the larger magnitude of interference to coordinate, because steel ball and the conical surface are 45 degree of angular contact, so not
As for the very big self-lock force of generation.
When the present invention uses, when product puts into plunger, plunger 4, along radially-inwardly shrinking, makes steel in the effect of pressure
Pearl moves downward, and spring, to the retroaction of steel ball, also can pass to product simultaneously, thus ensure that product will not be with processing
Alignment pin produces relative motion, and the upper-lower position adjusting base rice screw can achieve that the tensile force of alignment pin is adjusted, and has operation
Simply, the advantages of use safe, due to the adjustment of stress relation, clamping force can pass to spring, be effectively reduced alignment pin
Abrasion.
Brief description
Fig. 1 is a kind of structural representation of the present invention.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings:
As shown in the figure：A kind of elastic deformation alignment pin, including shank 1, steel ball 2, spring 3 and base rice screw 4, its feature
Be that shank is made up of key seat, pin body and plunger, in shank, be provided with the spring eye of axis and shank dead in line, spring eye upper
End is located at pin body and plunger junction and is in 45 degree of cone angles, and the lower end of spring eye is provided with blocking screw thread, at least provided with two in plunger
Bar deforms groove, and plunger in radial direction decile, is deformed groove lower end and is connected with spring eye top, spring in the hole is provided with steel ball by deformation groove
With spring and through base rice screw positioning, steel ball and spring eye top are in that 45 degree of conical surfaces are conflicted, and steel ball is presented herein below spring, below spring
It is base rice screw, during work, alignment pin and product endoporus have the larger magnitude of interference to coordinate, because steel ball and the conical surface are 45 degree of angles
Contact, so be unlikely to produce very big self-lock force.
When the present invention uses, when product puts into plunger, plunger 4 along radially-inwardly shrinking, steel under the effect of the pressure
Pearl can move downward, and spring, to the retroaction of steel ball, also can pass to product simultaneously, thus ensure that product will not in processing
Produce relative motion with alignment pin, the upper-lower position i.e. tensile force of achievable alignment pin adjusting base rice screw facilitates adjustable, tool
Have the advantages that simple to operate, using safe, the present invention can pass to spring, effectively due to the adjustment of stress relation, clamping force
Decrease the abrasion of alignment pin.
