Abstract

The utility model relates to a tensioning type positioning device, which mainly comprises positioning blocks, a cam and a positioning pin casing. At least two groups of the positioning blocks are uniformly distributed on the circumference of the positioning pin casing and radially and slidably matched with the same. A spanner groove is arranged in the center of the cam which is mounted in the center of the positioning pin casing, a limiting column and a return spring are mounted in an elongated round hole of each positioning block and fixed onto the positioning pin casing, and the cam, the positioning blocks and the positioning pin casing form a cam mechanism. The positioning blocks mounted on the positioning pin casing can move simultaneously, so that positioning holes at the same position of a multi-layer plate can forcedly be concentric. The positioning blocks are automatically locked when rotating to the apex of the cam, and accordingly tensioning and positioning of the multi-layer plate are realized by the aid of external positioning faces of the positioning blocks.

Description

The expansion chuck positioner
Technical field
The utility model patent relates to and fastens the bit architecture field, relates in particular to the positioner that the multilayer cut deal aligns fixed structure and frock clamp positioning and fixing.
Background technology
In truck manufacturing technology field, truck frame is made up of inside and outside doubling plate, inside and outside binding site postwelding associating die mould.Inner and outer plates dislocation when causing spot welding owing to stress raisers on the one hand in the pinpoint welding procedure; On the other hand since the distance of first spot welding point and the nearest alignment pin of last point solder joint more than 1.4 meters; Therefore during spot welding workpiece to have be in free state greatly; Be easy to cause inside and outside plate hole dislocation, have a strong impact on the assembling of postorder.
At other field, the plate that multilayer is in free state position positioning and fixing as requested also is a masty problem.General multipurpose circular alignment pin is prone to the problem that error is big or the location is difficult to take out with the location, hole or with limit, profile location.
Summary of the invention
In order to overcome above-mentioned shortcoming; The utility model provides a kind of swelling positioner; Orientation problem when having solved the spot welding of multilayer plate is relating to the other field that the multilayer plate aligns the location, can this expansion chuck positioner be placed to carry out the swelling location in the hole of multi-layer sheet same position.
The described a kind of swelling positioner of the utility model patent mainly is made up of locating piece, cam, alignment pin housing, and wherein at least two group locating pieces are uniformly distributed with and are distributed on the alignment pin housing circumference, radially are slidingly matched with the alignment pin housing; Cam center has the spanner groove, is installed in alignment pin housing center; Limited post and retracting spring are installed in the slotted hole of locating piece and are fixed on the alignment pin housing, cam and locating piece, alignment pin housing composition cam mechanism.
Open slot in said locating piece and the alignment pin housing is slidingly matched.
Said spanner groove is the die nut groove.
The positioning cylindrical surface diameter that said locating piece working face forms is less than the locating hole diameter of multilayer cut deal.
Through the spanner rotating cam; Drive locating piece radially motion simultaneously in mounting groove; Pin when arriving the cam vertex position; Utilize locating piece outside fix face to realize, automated backhaul when realizing stroke limit and loading and unloading by the slotted hole of limited post, locating piece and retracting spring to multiple-plate swelling location.
In truck manufacturing technology field, the orientation problem when utilizing this expansion chuck positioner to solve the spot welding of multilayer plate, the inner and outer plates dislocation when having eliminated the spot welding of truck longeron inner and outer plates has guaranteed the concentricity requirement of vehicle frame multi-layer sheet assembling with the hole.
Relating to the other field that the multilayer plate aligns the location, can this expansion chuck positioner placed and carry out the swelling location in the hole of multi-layer sheet same position, making cut deal material that multilayer is in free state position positioning and fixing as requested; Simultaneously, this device also can be used for swelling and takes out the frock clamp positioning and fixing structure that inner hole sleeve is arranged be inconvenient to take out etc.

Each component symbol among the figure:
Wherein 1, locating piece 2, limited post 3, retracting spring 4, cam 5, alignment pin housing 6, cover plate.
The specific embodiment
The described a kind of swelling positioning device structure of the utility model patent partly is made up of locating piece 1, cam 4, alignment pin housing 5, limited post 2, retracting spring 3, cover plate 6 etc.Three locating pieces 1 are installed in three open slots that alignment pin housing 5 upper edge circumference become 120 degree angles to be uniformly distributed with and are slidingly matched; Cam 4 centers are designed with the inner hexagon spanner groove, are installed in alignment pin housing 5 centers; Limited post 2 and retracting spring 3 are installed in the slotted hole of locating piece 1 and are fixed on the alignment pin housing 5.Cam 4 is formed cam mechanism with locating piece 1, alignment pin housing 5.
Before the location; Cam 4 is in cam 4 low spots with the cam mechanism that locating piece 1, alignment pin housing 5 are formed; The positioning cylindrical surface diameter of three groups of locating piece 1 working face formation is less than the locating hole diameter of multilayer cut deal, near the locating hole multi-layer sheet pad of being convenient to pack into.
The swelling location; Pack into behind the locating hole; Through common inner hexagon spanner rotating cam 4, drive the radially motion simultaneously in mounting groove of three groups of locating pieces 1, force the locating hole of multi-layer sheet same position to be realized with one heart; When turning to cam 4 vertex positions, pin automatically, utilize locating piece 1 outside fix face to realize multiple-plate swelling location.
Behind the location, after multi-layer sheet welding was accomplished, to low spot, under the effect of retracting spring 3, three groups of locating pieces 1 automated backhaul radially in alignment pin housing 5 grooves was up to limited post 2 stroke limits through inner hexagon spanner backward rotation cam 4.At this moment, the locating surface that locating piece 1 working face forms is convenient to from locating hole, take out smoothly less than aperture, multiple-plate location.
Location for the multilayer plate; When utilizing other frock clamp positioning and fixing; Generally need utilize circular alignment pin, its front end has taper seat or the chamfering of being convenient to put into, and the rear end has the shaft shoulder position of limiting the insertion position; The locating surface of circular alignment pin generally is measure-alike or smaller with locating hole, and circular alignment pin is fixed the back owing to receive each effect to power to be difficult to from locating hole, take out at plate; If utilize limit or plate profile location; Then need utilize the locating piece that conforms to plate limit or profile to position; Because the error of locating piece and plate self, this location generally bigger position error can occur, generally is not suitable for the higher positioning and fixing of position accuracy demand.
