Abstract

The utility model relates to a movable type fixture clamping positioner which is provided with a positioning head supporting seat fixed on a seat plate 2, and the positioning head supporting seat is provided with a supporting arm extended outwards; the supporting arm is provided with a V-shaped groove A and a plane B which are used for supporting a movable idler wheel positioning head; a compactor with an elbow is connected with an eyelet bolt through a shaft pin; and the shaft pin drives the compactor to press or open the idler wheel positioning head through the elasticity of an extension spring and a handle nut on the eyelet bolt. As the idler wheel positioning head can be pressed or opened by moving the compactor, the utility model well solves the problem that the positioning location of a fixing type positioning head on each product is fixed to cause that the technology hole positioning of the large-scale wall plate of the sheet metal with great tolerance frequently has the interference phenomenon in the prior art; the fast convenience greatly lightens labour intensity of workers; the difficult problems of difficult positioning, inaccurate positioning, difficult adjustment and bad coordination interchangeability of parts assembly fixture of the large-scale wall plates are changed.

Description

Movable type frame clamping and positioning device

Technical field

The utility model is about the medium-and-large-sized wallboard assembly jig of manufacturing industry location clamping and positioning device.

Background technology

For a long time, the assembly jig of the large-scale wallboard of assembling in the manufacturing, two fabrication hole locators about all being provided with usually.The positioning collet of these two fabrication hole locators nearly all is the relevant rigging position that is fixed on the type frame, generally can not move.Because tolerance is big often in the position of the large-scale wallboard class fabrication hole of sheet metal component class, it is indefinite to change, and therefore the position location interference of locator often takes place in assembling process.Because the volume of large-scale wallboard is very big, fabrication hole on it is positioned seem unusual difficulty of existing fixed formula positioning head.To coordinate interchangeability poor so this fixed locator exists, location difficulty, locate inaccurate, the problem that the tonality difficulty is big, and the labour intensity in the tonality is bigger.

Summary of the invention

The purpose of this utility model is to provide a kind of movable type frame clamping and positioning device, to change large-scale wallboard class part assembly jig location difficulty, locate inaccurate, the tonality difficulty is big, coordinates the problem of interchangeability difference.

To achieve these goals, a kind of movable type frame clamping and positioning device that the utility model provides, have one and be fixed on two positioning head bearings on the seat board by left and right orientation, have a support arm that extends outward on the described positioning head bearing, be shaped on the V-shaped groove A (left side) and the plane B (right side) of the roller positioning head that supporting can move about on the support arm, the compactor that is shaped on elbow is connected in eyelet bolt by pivot pin, and the degree of tightness by extension spring on the eyelet bolt and handle nut, drive compactor by pivot pin and compress or open described roller positioning head 10.

The utility model has following beneficial effect than prior art.

The location that the utility model compressed or opened the roller positioning head by movable compactor compresses mode, and to have solved the fixed positioning head of prior art well be to immobilize to the position of the location of each product, makes the large-scale wallboard class fabrication hole location of the big sheet metal component class of tolerance often to interfere the problem of phenomenon;

Because its location compressing structure has independence, therefore manufactures also very convenient.The roller positioning head that locator independently can move about is very easy to use, it is worked good with large-scale wallboard product fabrication hole separately earlier, then with they together placement positioning on the support arm 9 that positioning head bearing 8 has, more embody its superiority easily and efficiently, greatly alleviated working strength of workers.Changed large-scale wallboard class part assembly jig location difficulty, locate inaccurate, the tonality difficulty is big, coordinates the difficult problem of interchangeability difference.

Description of drawings

Further specify the utility model below in conjunction with drawings and Examples, but therefore the utility model is not limited among the described scope of embodiments.

Fig. 2 is the partial schematic diagram of left positioning head support arm 13 among Fig. 1.

Fig. 3 is the schematic diagram of right positioning head support arm 14 parts among Fig. 1.

Fig. 4 is the schematic side view of Fig. 1.

Among the figure: 1. compactor, 2. seat board, 3. locking nut, 4. extension spring, 5. handle nut, 6. pivot pin, 7. baffle plate, 8. positioning head bearing, 9. support arm (left and right), 10. roller positioning head, 11. eyelet bolt, 12. elliptical apertures, 13. left positioning head support arms, 14. right positioning head support arms.

The specific embodiment

Consult Fig. 1～Fig. 4, the positioning head bearing 8 that has left positioning head support arm 13 is fixedly connected on the seat board 2.The upper surface of positioning head bearing 8 has a support arm that extends outward 9, is shaped on the V-shaped groove A of the roller positioning head 10 that supporting can move about on the support arm 9.The roller positioning head 10 that forward is positioned on the support arm 9 circumferentially is shaped on cannelure, and roller positioning head 10 is positioned on the V-shaped groove A and right positioning head support arm plane B on the support arm 9 by cannelure.A gusset that is vertically fixed on the pivot pin 6 of seat board 2 and has elliptical aperture 12 is arranged below support arm 9 that positioning head bearing 8 has, compactor 1 connects eyelet bolt 11 by pivot pin 6, and pivot pin 6 drives the compactor 1 that is shaped on elbow by the motion in elliptical aperture 12 and compresses or open; And compactor 1 can be regulated degree of tightness by extension spring on the eyelet bolt 11 4 and handle nut 5; Compactor 1 is adjusted height by extension spring 4 simultaneously.Extension spring 4 can be adjusted amount of tension by handle nut 5 and regulate the scope of activities of pivot pin 6 in vertical elliptical aperture 12, compresses with locking nut 3 at last.So tighten and unclamp by handle nut 5, pivot pin 6 drives compactors 1 and eyelet bolt 11 just can compress compactor 2 and open along elliptical aperture 12.

During use, earlier with about each one, two fabrication holes are had good positioning about on two roller positioning heads that can move about 10 and the big skinpiston, by the location of roller positioning head 10 on the support arm 9 that positioning head bearing 8 has big skinpiston is located then, again with the compactor 1 that has extension spring 4, the V-shaped groove A that roller positioning head 10 is pressed on support arm 9 go up and right positioning head support arm 14 plane B on, with locking nut 3 the skinpiston product is compressed at last.

Two positioning head bearings 8 about the utility model locator has, the support arm 9 that one of them positioning head bearing 8 has is shaped on can the move about V-shaped groove A of positioning head 10 of a location, 9 of the support arms that another positioning head bearing 8 has are made a plane B and are located the positioning head 10 that can move about, and this positioning head 10 that can move about can be done electrodeless adjustment on this plane; Locate earlier by the V-shaped groove A of one of them positioning head 10 during use with positioning head bearing 8, another positioning head 10 is done the location that can move about on the B of the plane of another positioning head bearing 8, therefore well solved large-scale wallboard class part assembly jig location difficulty, locate inaccurate, the tonality difficulty is big, coordinates the difficult problem of interchangeability difference.
