Abstract
The utility model provides a welding clamp of grading ring connecting pieces. The welding clamp of the grading ring connecting pieces is simple in structure and guarantees that the axis of a circumference formed by a plurality of connecting pieces is consistent with that of a grading ring. The welding clamp comprises a main driving mechanism, a plurality of driven mechanisms and a plurality of clamps, wherein the main driving mechanism is vertically arranged, and the driven mechanisms are horizontally arranged and are connected to the main driving mechanism in a staggered mode. The clamps are connected to the ends, far away from the main driving mechanism, of the driven mechanisms, and the heights of jaws of the clamps are consistent. The main driving mechanism comprises a driving motor and a driving gear which is connected to an output shaft of the driving motor. Each driven mechanism comprises a worm wheel and a worm both of which are matched with the driving gear to enable the driving gear to drive the worms to move horizontally at the same time. The welding clamp effectively solves the problem that the axis of the circumference formed by the connecting pieces is inconsistent with that of the grading ring.
Description
Technical field
The utility model relates to the anchor clamps field, relates in particular to the improvement of the anchor clamps that use in the welding.
Background technology
Grading ring can be evenly distributed on high voltage around the object, and guaranteeing does not have potential difference between an annular position, thereby reaches the effect of all pressing.It 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. by the use difference.For making grading ring be to use effect better, usually with grading ring a by the top that some connector b are fixedly connected on an axis, 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 finished, the axle center of the circumference of its formation is consistent with the axle center of grading ring.
The utility model content
The utility model provides a kind of simple in structure at above problem, guarantees 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.
The technical solution of the utility model is: comprise vertically disposed main driving machine structure, some horizontally disposed followers and some clamps; Some described followers are cross-linked on the main driving machine structure, and described clamp is connected described follower away from the end of described main driving machine structure and the jaw height unanimity of some clamps;
Described main driving machine structure 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 horizontal displacement simultaneously.
The diameter of described driven wheel is less than the diameter of described worm gear.
The utility model is because the worm gear of each follower is all identical with worm screw, then the overhang of each worm screw equates after operation, and then will make after strutting fully that the axle center of grading ring is consistent with the axle center of main driving machine structure, also make that the axle center of the circumference that some connectors form is also consistent with the axle center of main driving machine structure simultaneously.Therefore, can make that the axle center of the circumference that some connectors form is 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.
Description of drawings
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the vertical view of Fig. 1;
1 is the main driving machine structure among the figure, the 11st, and drive motors, the 12nd, driven wheel, the 2nd, follower, the 21st, worm gear, the 22nd, worm screw, the 3rd, clamp, a are grading rings, b is connector.
The specific embodiment
The utility model comprises vertically disposed main driving machine structure 1, some horizontally disposed followers 2 and some clamps 3 shown in Fig. 1-2; Some described followers 2 are cross-linked on main driving machine structure 1, make each follower 2 can not interfere mutually when operation, described clamp 3 is connected described follower 2 away from the end of described main driving machine structure 1 and the jaw height unanimity of some clamps 3; Then the connector b of jaw 3 places clamping also will be on the sustained height;
Described main driving machine structure 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 the worm gear 21 of each follower 2 is all identical with worm screw 22, makes described driven wheel 12 can drive some described worm screws 22 and carries out horizontal displacement simultaneously.Like this, because the overhang of each worm screw 22 equates after operation, to make after then strutting fully that the axle center of grading ring a is consistent with the axle center of main driving machine structure 1, make also simultaneously that the axle center of the circumference that some connector b form is also consistent with the axle center of main driving machine structure 1, therefore, can make that the axle center of the circumference that some connector b form is consistent with the axle center of grading ring a.
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 machine structure 1 generation movement interference.
