Abstract
The utility model relates to a fixture, in particular to an elastic deformation locating pin. The elastic deformation locating pin comprises a pin body, a steel ball, a spring and a grub screw and is characterized in that the pin body consists of a pin seat, a pin main body and a pin head; a spring hole of which the axis is overlapped with the axis of the pin body is formed in the pin body; the upper end of the spring hole is arranged at the joint of the pin main body and the pin head and has a 45-degree taper angle; the lower end of the spring hole is provided with sealing threads; the pin head is provided with at least two deformation grooves; the deformation grooves equally divide the pin head 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 in the spring hole and are located by the grub screw; the steel ball is butted against the top end of the spring hole by a 45-degree taper angle; the spring is arranged below the steel ball; the grub screw is arranged below the spring; during work, the locating pin is matched with an inner hole of a product in great interference fit, and because the steel ball is in 45-degree angle contact with a conical surface, great self-locking force cannot be generated. The tension of the locating pin can be convenient to adjust by adjusting the grub screw vertically, the elastic deformation locating pin is easy to operate and safe to use, clamping force can be transmitted to the spring because of the regulation of a stress relationship, and the abrasion of the locating pin is effectively reduced.
Description
Technical field
The present invention relates to a kind of fixture, specifically the resiliently deformable locating stud of a kind of easy to operate, reliable operation, stable performance.
Background technique
We know, need a lot of locating studs in the time of commutator pipelining, and these locating studs must possess, and elasticity, can not have relative movement while being placed in above it with convenient product preferably, just can play good positioning action.Particularly voltage-withstand test this part, often, because pin disappears because long term wear causes pin resiliently deformable, causes product orientation to be forbidden and appearance erroneous judgement.
Summary of the invention
Object of the present invention is exactly in order to overcome prior art, a kind of easy to operate, reliable operation, stable performance is provided, realizes the elastic positioning pin of a tractor serves several purposes.
The technological scheme that the present invention solves the problems of the technologies described above employing is.
A kind of resiliently deformable locating stud, comprise shank, steel ball, spring and base rice screw, it is characterized in that shank is by key seat, pin body and plunger composition, in shank, be provided with the spring eye of axis and shank dead in line, the upper end of spring eye is located at pin body and plunger joint and is 45 degree cone angles, the lower end of spring eye is provided with blocking screw thread, in plunger, be at least provided with two distortion grooves, distortion groove by plunger at decile radially, distortion groove lower end is connected with spring eye top, in spring, be provided with steel ball and spring and locate through base rice screw, steel ball and spring eye top are the 45 degree conical surfaces and conflict, it below steel ball, is spring, it below spring, is base rice screw, when work, when locating stud and product endoporus, there is larger magnitude of interference to coordinate, because steel ball and the conical surface are that miter angle contacts, so be unlikely to produce very large self-lock force.
The utility model can be provided with four distortion grooves in plunger, and distortion groove is by plunger 4 parts of deciles radially, and distortion groove lower end is connected with spring eye top respectively.
When the present invention uses, in the time that product is put into plunger, plunger 4 half, along radially inwardly shrinking, is pressing line of action of force steel ball to move downward, and spring, to the reaction of steel ball, also can pass to product simultaneously.Thereby guarantee that product can not produce relative movement with locating stud adding man-hour.The tension force that regulates the upper-lower position of base rice screw can realize locating stud facilitates adjustable, have simple to operate, use safety, due to the adjustment of stressed relation, clamping force can pass to spring, has effectively reduced the wearing and tearing of locating stud.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure: a kind of resiliently deformable locating stud, comprise shank 1, steel ball 2, spring 3 and base rice screw 4, it is characterized in that shank is by key seat, pin body and plunger composition, in shank, be provided with the spring eye of axis and shank dead in line, the upper end of spring eye is located at pin body and plunger joint and is 45 degree cone angles, the lower end of spring eye is provided with blocking screw thread, in plunger, be at least provided with two distortion grooves, distortion groove by plunger at decile radially, distortion groove lower end is connected with spring eye top, in spring, be provided with steel ball and spring and locate through base rice screw, steel ball and spring eye top are the 45 degree conical surfaces and conflict, it below steel ball, is spring, it below spring, is base rice screw, when work, when locating stud and product endoporus, there is larger magnitude of interference to coordinate, because steel ball and the conical surface are that miter angle contacts, so be unlikely to produce very large self-lock force.
When the present invention uses, in the time that product is put into plunger, plunger 4 half, along radially inwardly shrinking, is pressing line of action of force steel ball to move downward, and spring, to the reaction of steel ball, also can pass to product simultaneously.Thereby guarantee that product can not produce relative movement with locating stud adding man-hour.The tension force that regulates the upper-lower position of base rice screw can realize locating stud facilitates adjustable, have simple to operate, use safety, due to the adjustment of stressed relation, clamping force can pass to spring, has effectively reduced the wearing and tearing of locating stud.
