CN103111787A - Welding fixture for equalizing ring connecting pieces - Google Patents

Abstract

The invention discloses a welding fixture for equalizing ring connecting pieces, which is simple in structure and can guarantee that the axis of the circumference formed by a plurality of connecting pieces is consistent with the axis of an equalizing ring. The welding fixture comprises a vertical main driving mechanism, a plurality of horizontal driven mechanisms and a plurality of clamps, wherein the driven mechanisms are connected to the main driving mechanism in a staggered mode; the clamps are connected to the ends, which are far away from the main driving mechanism, of the driven mechanisms; the openings of the clamps are consistent in height; the main driving mechanism comprises a driving motor and a driving gear; the driving gear is connected to an output shaft of the driving motor; and the driven mechanisms comprise worm gears and worms, which are matched with the driving gear, so that the driving gear can drive the worms to horizontally move. The welding fixture effectively solves the problem that the axis of the circumference formed by a plurality of connecting pieces is inconsistent with the axis of an equalizing ring.

Description

A kind of weld jig of grading ring connector

Technical field

The present invention relates to the fixture field, relate in particular to the improvement of the fixture that uses in welding.

Background technology

Grading ring can be evenly distributed on high voltage around object, and guaranteeing does not have potential difference between an annular position, thereby reaches the effect of all pressing.They are different by use, can be divided into lightning-arrest grading ring, lightning protection grading ring, mutual inductance grading ring, high-tension testing apparatus grading ring, power transmission and transformation line grading ring etc.Be that result of use is better for making grading ring, usually grading ring a be fixedly connected on the top of an axis by some connector b, like this, just must guarantee the precision of the axiality of grading ring and axis.Because the position of mounting hole on some connectors is identical, therefore, for guaranteeing the positional precision of axis and grading ring, just must guarantee some connectors after welding is completed, the axle center of the circumference of its formation is consistent with the axle center of grading ring.

Summary of the invention

The present invention is directed to above problem, provide a kind of simple in structure, guarantee the weld jig of the grading ring connector that the axle center of the circumference that some connectors form is consistent with the axle center of grading ring.

Technical scheme of the present invention is: comprise vertically disposed main driving mechanism, some horizontally disposed followers and some clamps; Some described followers are cross-linked on main driving mechanism, and it is consistent away from the jaw height of the end of described main driving mechanism and some clamps that described clamp is connected to described follower;

Described main driving mechanism comprises drive motors and driven wheel, described driven wheel is connected on the output shaft of described drive motors, described follower comprises worm gear and the worm screw adaptive with described driven wheel, makes described driven wheel can drive some described worm screws and carries out simultaneously horizontal displacement.

The diameter of described driven wheel is less than the diameter of described worm gear.

The present invention is because worm gear and the worm screw of each follower are all identical, the overhang of each worm screw equates after operation, and then will make the axle center of grading ring consistent with the axle center of main driving mechanism after strutting fully, also make simultaneously the axle center of the circumference that some connectors form also consistent with the axle center of main driving mechanism.Therefore, can make the axle center of the circumference that some connectors form consistent with the axle center of grading ring.The axle center of the circumference that some connectors form and the inconsistent problem in axle center of grading ring have effectively been solved.

The specific embodiment

The present invention comprises vertically disposed main driving mechanism 1, some horizontally disposed followers 2 and some clamps 3 as shown in Fig. 1-2; Some described followers 2 are cross-linked on main driving mechanism 1, make each follower 2 time can mutually not interfere in operation, it is consistent away from the jaw height of the end of described main driving mechanism 1 and some clamps 3 that described clamp 3 is connected to described follower 2; The connector of jaw 3 places clamping also will be on sustained height;

Described main driving mechanism 1 comprises drive motors 11 and driven wheel 12, described driven wheel 12 is connected on the output shaft of described drive motors 11, described follower 2 comprises worm gear 21 and the worm screw 22 adaptive with described driven wheel 12, because worm gear 21 and the worm screw 22 of each follower 2 are all identical, make described driven wheel 12 can drive some described worm screws 22 and carry out simultaneously horizontal displacement.Like this, because the overhang of each worm screw 22 after operation is equal, to make the axle center of grading ring consistent with the axle center of main driving mechanism 1 after strutting fully, also make simultaneously the axle center of the circumference that some connectors form also consistent with the axle center of main driving mechanism 1, therefore, can make the axle center of the circumference that some connectors form consistent with the axle center of grading ring.

The diameter of described driven wheel 12 is less than the diameter of described worm gear 21.Effectively avoided worm screw 22 at when operation and main driving mechanism 1 generation movement interference.
