Abstract
The invention provides a ball head positioning device for positioning irregular workpieces in a combined clamp and a positioning method of the ball head positioning device. The ball head positioning device comprises a ball, a boss and a cylinder which are connected in sequence and of which center lines are superposed. The positioning method includes steps of firstly simulating positioning by a computer, namely simulating to arrange a workpiece at a correct position and arrange the ball head positioning device near a form surface to be positioned; keeping the ball surface of the ball head positioning device in point contact with the form surface to be positioned of the workpiece by contacting function of a computer three-dimensional design system; measuring coordinate sizes of various surfaces of a clamp base body away from the ball center point of the ball head positioning device by means of a computer three-way measuring function after simulating positioning of the computer is finished, then adjusting workpieces positions of a combined clamp fittingly connected with the ball head positioning device, and finally accurately positioning the workpiece. The ball head positioning device solves the problem that conventional combined clamps cannot position irregular workpieces.
Description
Technical field
The present invention relates to be used in a kind of built-up jig bulb positioner and the localization method thereof of location irregular part, belong to built-up jig design and manufacturing technology field.
Background technology
In the built-up jig production process, when the location of product parts benchmark is irregular profiles such as inclined-plane, compound angle face, curved surface, use existing combination-fixture component can't realize accurate location, this is because the element in the universal jig and fixture system substantially all is the geometric shape with rule, it is rectangular-shaped to be straightedge, when the locating surface of product parts is irregular, be difficult to reach the state that setting element and reference surface are fitted fully.Traditional way is " approximate adjust " or adjust by line, but the anchor clamps positioning accuracy is low, therefore is difficult to guarantee product quality.
Summary of the invention
The purpose of this invention is to provide the bulb positioner and the method thereof that are used for the location irregular part in the built-up jig, having solved the conventional combination anchor clamps can't be to the problem of irregular workpiece location.
Technical scheme of the present invention: the bulb positioner that is used for the location irregular part in the built-up jig, comprise spheroid, round platform and cylinder, above-mentioned three connects and three's central lines in turn, and the cylinder end car has screw thread, and cylinder is threaded with clip base.
Be used in the built-up jig location irregular part a kind of localization method, it adopts above-mentioned bulb positioner, may further comprise the steps:
(1) carries out the computer simulation location earlier, being about to the workpiece simulation puts to the tram, the bulb positioner is placed near the profile that needs the location, and the bulb positioner need guarantee that its center line is not only parallel with the horizontal plane of clip base but also vertical with the vertical plane of clip base on being positioned over clip base the time;
(2) utilize the spherome surface that contact function in the Computerized three-dimensional design system makes the bulb positioner to contact with point on the profile that workpiece need be located, it is mobile at centerline direction to remain the bulb positioner in the contact process;
(3) after the computer simulation location finishes, utilize the Computerized three-dimensional measurement function to measure the ball centre point of bulb positioner apart from each surperficial coordinate dimension of clip base earlier, adjust the combination-fixture component position that is connected with the bulb positioner, the accurate location of finally realizing workpiece then.
Beneficial effect of the present invention:
The barrier that is difficult to realize a contact when 1, having broken through the combination-fixture component location is simplified the face location and is point location, and to locate more accurate;
2, adopt Computerized three-dimensional simulation assembling and measuring technique, avoided complicated calculations and the conversion of a lot of intermediate links, data directly, reliably;
3, simplify the built-up jig structure greatly, improved precision and the stability of anchor clamps;
4, can be applicable to locate the product parts that benchmark is various irregular profiles such as curved surface, inclined-plane, compound angle face.

Be used in the built-up jig location irregular part a kind of localization method, it adopts above-mentioned bulb positioner, may further comprise the steps:
(1) carries out the computer simulation location earlier, being about to workpiece 2 simulations puts to the tram, bulb positioner 3 is placed near the profile that needs the location, bulb positioner 3 need guarantee that its center line is not only parallel with the horizontal plane of clip base 1 but also vertical with the vertical plane of clip base 1 on being positioned over clip base 1 time, as shown in Figure 2;
(2) utilize spherome surface that contact function in the Computerized three-dimensional design system makes bulb positioner 3 and workpiece 2 to need the point on the profile of location to contact, and guaranteeing that spheroid is tangent with the location profile, it is mobile at centerline direction to remain bulb positioner 3 in the contact process;
(3) after the computer simulation location finishes, utilize the Computerized three-dimensional measurement function to measure the ball centre point of bulb positioner 3 apart from clip base 1 each surperficial coordinate dimension earlier, adjust the combination-fixture component position that is connected with bulb positioner 3, the accurate location of finally realizing workpiece 2 then.
When needs a plurality of bulb positioners are installed, are got final product according to the above-mentioned steps repetitive operation.
Claims (2)
