The magnetic force resetting end face contacting-type positioning structure solves the technical problems that an end face contacting-type positioning structure is instable in combine force, and affects accuracy of positioning and connecting and consistency of positioning accuracy particularly after being used for a period of time. According to the technical scheme, the positioning device is composed of positioning balls and positioning cylinders, the positioning balls are evenly and fixedly arranged on the connecting end face of an upper connecting body in pairs with the inclined angle of 120 degrees, and the positioning cylinders are evenly and fixedly arranged on the connecting end face of a lower connecting body in the radial direction in the inclined angle of 120 degrees, so that an axial positioning structure and a radial positioning structure of the upper connecting body and an axial positioning structure and a radial positioning structure of the lower connecting body when each pair of positioning balls is in contact with corresponding positioning cylinders are formed, and permanent magnets are arranged on the upper connecting body and the lower connecting body. The magnetic force resetting end face contacting-type positioning structure has the advantages of being simple in structure, high in positioning accuracy, particularly high in repetitive positioning accuracy, good in consistency, and particularly suitable for being applied to measuring devices or high precision instruments.
Description
Technical field
The utility model relates to the position structure, particularly a kind of position structure that is applicable to guarantee when end face repeatedly repeats to connect its radial and axial connection Location accuracy that a kind of mechanical end face connects.
Background technique
End face is connected to common linkage structure in the mechanical structure, in the existing linkage structure that needs to locate, positioning means is to adopt positioning hole and the orientation types such as locating stud, taper hole and taper pin, ball and groove, referring to accompanying drawing 1,2,3, such as the position structure of ball 7 with groove 8, the shortcoming of existing orientation type is that Location accuracy is low, and particularly repetitive positioning accuracy is low, the needs that particularly existing orientation type can't satisfy modern precision processing and measure on measuring tool.The measuring accuracy of using such as mechanical measurement is at the contact type measurement head of a thousandth millimeter; chaining pin is installed on the chaining pin seat; chaining pin seat and measuring head end face are flexibly connected; chaining pin seat and measured workpiece or chaining pin seat are changed bridge joint after touch; the chaining pin seat disconnects with the measuring head end face and separating; play the purpose of protection chaining pin seat and quick-replaceable chaining pin seat; re-starting when measuring next time; reorientate with the measuring head end face with the chaining pin seat and to be connected, this just requires precision that end face is located by connecting and the conformity of Location accuracy.The combination force that end face is located by connecting in the prior art is to adopt spring or mechanical thrust to realize that its shortcoming is that combination force is unstable, particularly use a period of time after, also be the precision that is located by connecting of impact and the conforming factor of Location accuracy.
The model utility content
For overcoming in the prior art, the combination force that the precision that end face is located by connecting and the conformity of Location accuracy and end face are located by connecting is unstable and affect Location accuracy, the utility model discloses a kind of magnetic force resetting end contact formula position structure, overcomes the deficiencies in the prior art.
The utility model realizes that the technological scheme that goal of the invention adopts is: a kind of magnetic force resetting end contact formula position structure, comprise: upper connecting body, lower connecting body and upper, the positioning device that arranges on the lower connecting body, described positioning device is made of place kick and positioning cylinder, described place kick is in pairs by on 120 ° of uniform connecting end surfaces that are fixedly installed on upper connecting body, described positioning cylinder is by on 120 ° of uniform connecting end surfaces that radially are fixedly installed on lower connecting body, upper connecting body when consisting of every pair of place kick with the contact of corresponding positioning cylinder and the axial and radial positioning structure of lower connecting body, be respectively arranged with permanent magnet on described upper connecting body and the lower connecting body, the permanent magnet that has that arranges on upper connecting body and the lower connecting body oppositely arranges.
The beneficial effects of the utility model are that Location accuracy height, particularly repetitive positioning accuracy simple in structure are high, high conformity.Be specially adapted to use at measuring device or highly sophisticated device.

In the accompanying drawing, 1 place kick, 2 positioning cylinders, connecting body on 3,4 times connecting bodys, 5 permanent magnets, 6 place kick pits, 7 balls, 8 grooves.
Embodiment
Referring to accompanying drawing 4,5 and 6, a kind of magnetic force resetting end contact formula position structure, comprise: upper connecting body, lower connecting body and upper, the positioning device that arranges on the lower connecting body, described positioning device is made of place kick 1 and positioning cylinder 2, described place kick 1 is in pairs by on 120 ° of uniform connecting end surfaces that are fixedly installed on upper connecting body 3, described positioning cylinder 2 is by on 120 ° of uniform connecting end surfaces that radially are fixedly installed on lower connecting body 4, upper connecting body 3 when consisting of every pair of place kick 1 with 2 contact of corresponding positioning cylinder and lower connecting body 4 axially and radial positioning structure, be respectively arranged with permanent magnet 5 on described upper connecting body 3 and the lower connecting body 4, the permanent magnet 5 that has that arranges on upper connecting body 3 and the lower connecting body 4 oppositely arranges.
During use by the magnetic force of permanent magnet 5 oppositely is set, upper connecting body 3 is connected with the end face of lower connecting body 4, paired place kick 1 on upper connecting body 3 end faces contacts with positioning cylinder 2 on lower connecting body 4 end faces, size by place kick 1 and positioning cylinder 2 itself and positional accuracy guarantee upper connecting body 3 and lower connecting body 4 axially and radial location, because place kick 1 is adopted high-abrasive materials processing with positioning cylinder 2, guarantee that this structure reuses and do not affect its Location accuracy.
Because upper connecting body 3 is by permanent magnet 5 realization to be set oppositely with the combination force of lower connecting body 4, its combination force is constant, and elimination affects its Location accuracy owing to combination force is unstable.
