Technical field

The present invention relates to a kind of wig-wag fields, and in particular to a kind of crank block wig-wag of adjustable oscillation amplitude.

Background technique

It is higher and higher to the performance requirement of workpiece in many mechanical chemical industry fields with the fast development of modern industry, Many workpiece require long-term stable operation under the conditions ofs high temperature, high pressure, high speed etc., thus propose more to the performance of workpiece material High requirement.Built-up welding deposition technology is more and more especially industrially used in boiler industry, at one layer of workpiece surface deposition Wear-resisting or corrosion resistance alloy-layer, which can greatly increase, improves its service life, and can also save material, has preferable Economy.This butt welding deposition technology is more demanding to the moulding process of material, needs welding gun energy when realizing this technology Enough fast reciprocatings are swung, and wig-wag common on current market mostly uses the modes such as ball-screw and sliding friction, pendulum The wobble frequency of dynamic device at most can only achieve 4 times or so, can not continue to improve, and designed using common four-bar linkage mode Wig-wag can not adjust the amplitude of oscillation or adjust amplitude of oscillation difficulty, so the adjustment amplitude of oscillation can be facilitated and have high speed wobble frequency by being badly in need of design Wig-wag.

In conclusion because existing weldering deposition technology is more demanding to the moulding process of material, but existing wig-wag Wobble frequency can only achieve 4 or so, can not adjust hunting frequency and oscillating stroke, not be able to satisfy the needs of processing, so as to cause using Range is relatively narrow, problem larger using wig-wag size caused by bearing, inconvenient for use.

Summary of the invention

The present invention is to solve that existing weldering deposition technology is more demanding to the moulding process of material, but existing wig-wag Wobble frequency can only achieve 4 times or so, can not adjust hunting frequency and oscillating stroke, not be able to satisfy the needs of processing, so as to cause making Problem relatively narrow with range, larger using wig-wag size caused by bearing, inconvenient for use, and propose a kind of song of adjustable oscillation amplitude Handle sliding block wig-wag.

A kind of crank block wig-wag of adjustable oscillation amplitude of the invention, composition include motor, motor mounting rack, wig-wag Fixed frame, adjustment slide unit, track installation frame, sliding block, sliding rail, connecting rod, sliding block fixed frame, welding gun and rifle folder；

The output end of motor passes through motor mounting rack and is fixedly connected with adjustment slide unit bottom surface, and motor mounting rack is fixed on electricity On machine shell, the side of motor mounting rack is fixedly connected with the side of wig-wag fixed frame, and is adjusted slide unit setting and pacified in motor It shelves between wig-wag fixed frame, track installation frame is L-type mounting rack, and the side of motor mounting rack is short with track installation frame Wall side is fixedly connected, and the long-armed side of track installation frame is equipped with sliding rail, and sliding rail and adjustment slide unit are arranged ipsilateral, on sliding rail Equipped with sliding block, the side of sliding block is fixedly connected with the side of sliding block fixed frame, and one end of sliding block fixed frame side is pressed from both sides equipped with rifle, weldering One end of rifle is pressed from both sides across rifle, is fixed on sliding block fixed frame, and the other end of sliding block fixed frame side and one end of connecting rod are hinged, even The other end of bar and adjustment slide unit are hinged；

Further, the adjustment slide unit includes slid platform base, slide block assembly, dovetail groove sliding rail and lead screw；

Slid platform base quadrangle is respectively equipped with locating slot, and the four corners of dovetail groove sliding rail are respectively equipped with locating piece, slid platform base Upper surface is equipped with dovetail groove sliding rail, and the locating slot that the locating piece of the four corners of dovetail groove sliding rail and slid platform base quadrangle go out, which cooperates, to be connected It connects, and is equipped with cavity between slid platform base and dovetail groove sliding rail, lead screw is arranged in the cavities, and the both ends of lead screw and slid platform base turn Dynamic connection, slide block assembly are set on lead screw, and slide block assembly and lead screw are rotatablely connected, in the middle part of slide block assembly and dovetail groove sliding rail Dovetail groove be slidably connected；

Further, the slide block assembly includes dovetail groove sliding block and rotating nut, and rotating nut is set along outer round surface There is a dovetail groove sliding block；

Further, hinge column is equipped at the dovetail groove sliding block upper surface center；

Further, the other end of the connecting rod with it is hinged column articulated on dovetail groove sliding block；

Further, affiliated track installation frame is fixed to motor mounting rack 2 by way of welding or screw connection On；

Further, a copper sheathing is all lined in the connecting rod two end hinge hole；

Further, the motor is servo motor；

Further, when in use, by electric motor starting, the output shaft of motor is rotated, and drives adjustment slide unit rotation, and adjustment is slided Platform, connecting rod and sliding block constitute a slider-crank mechanism, and sliding block upper surface is equipped with, and the rotation of adjustment slide unit passes through connecting rod band movable slider The sliding block of fixed frame side does horizontal reciprocating movement on the slide rail, and welding gun is fixed on sliding block fixed frame by rifle folder, makes welding gun Do horizontal reciprocating movement；

To adjust welding gun the amplitude of oscillation frequency when, adjust adjustment slide unit on lead screw, rotational lead screw, adjusting slider component Position, so that the stroke of welding gun sliding can also be adjusted.

Compared with the prior art, the invention has the following beneficial effects:

One, wig-wag of the invention has used the principle of crank block, only needs motor continuous rotation in the course of work, is not necessarily to It moves back and forth, the service efficiency of motor can be greatly improved in this way, make wig-wag that there is the wobble frequency of high speed, wobble frequency reaches as high as often Second 10 times.

Two, the driving motor of wig-wag of the invention uses servo motor, stepper motor that more typical wig-wag uses and Direct current generator can more accurately control the amplitude of oscillation, while can also remember the start position of welding gun, can effectively ensure that every time Welding gun starting and welding gun starting point facilitates the molding of welding bead all in same point when stopping, while increasing after speed reducer in wobble frequency Output torque needed for motor can be effectively reduced in the case where reaching requirement effectively lowers the power of motor.

Three, wig-wag of the invention can be adjusted amplitude of fluctuation by rotary screw, and adjusting range is wide, adjustment side Just.

Four, in addition to a small number of necessary parts is using steel, the material of remaining most of part is all selected wig-wag of the invention With aluminium alloy, the weight of wig-wag can be effectively reduced in this way, keep its scope of application wider, facilitate on a robotic arm and other Occasion.

Five, it is all lined with a copper sheathing in wig-wag connecting rod two end hinge hole of the invention, can so makes the rotation of connecting rod It is more smooth, at the same also avoid conventional method use it is oversized caused by bearing.
