Abstract
The utility model discloses a multifunctional repair machine comprising a transformer, which is characterized in that the secondary windings of the transformer is electrically connected with a rectification circuit disposed among the same; the output end of the rectification circuit is electrically connected to a filtering constant voltage circuit constituted by a three terminal regulator and a filtering capacitor and a working capacitor; a pulse width modulation module is connected to a primary windings of the transformer. The utility model has advantages of low energy consumption, fast local heating, thereby the resistance of damaged part to be repaired can generate heat to melt the repair material through the instant pulsed discharge between the positive and negative pole of the working capacitor during the repairing process, so that the problem of prior art such as deformation caused by operation of a cold welding machine, cracks or even reject caused by partially heating can be solved, and the quality of lifetime of the repaired part can be improved.
Description
Technical field
The utility model relates to automobile, flight-line maintenance field, especially relates to multi-functional repairing machine.
Background technology
Automobile, flight-line maintenance industry are used for the damage parts are repaired, as: because of excess load or lack the reparation of axis hole that lubricating oil damages, the damage of engineering machinery hydraulic bar etc., take cold welding machine to repair at present during automobile engine used more.The deficiency of its existence mainly shows as and has the too high problem of local temperature in the mending course, causes by repairing parts easy deformation or because of crackle appears in local heating and scraps; Next be have that power is little, speed is slow, energy consumption is high, must be with deficiencies such as welding rod special for special; Position existence fusing after the repairing is shallow, combination is not firm, be difficult for processing problems.
The utility model content
The utility model purpose is to provide that a kind of energy consumption is little, the multi-functional rapidly repairing machine of local heat.
For achieving the above object, the utility model can be taked following technical proposals:
Multi-functional repairing machine described in the utility model, it comprises transformer, be electrically connected with rectification circuit between described transformer secondary output winding, described rectification circuit output end is electrically connected with mutual capacitance by the filter regulator circuit that is made of three terminal regulator, filter capacitor; Be connected with the pulse width modulation module in the primary winding electric.
Described transformer is the power frequency step-down transformer.
The utility model advantage is that energy consumption is little, local heat is rapid, therefore, when the damage parts are repaired, discharge by the momentary pulse between the described mutual capacitance positive and negative electrode, make to repair the resistance heating fusing of parts injury region and mend material, thereby having solved existing cold welding machine work time causes and repair that parts are out of shape or the deficiency that crackle is scrapped occurs because of local heating.The quality and the service life of repairing the back parts have been improved greatly.
Description of drawings
Fig. 1 is a schematic block circuit diagram of the present utility model.
The specific embodiment
As shown in the figure, multi-functional repairing machine described in the utility model, comprise the power frequency step-down transformer, be electrically connected with full-wave bridge rectifier circuit between described power frequency step-down transformer secondary windings, described rectification circuit output end is electrically connected with mutual capacitance C5 by the filter regulator circuit that is made of three terminal regulator, filter capacitor C1, C2, C3, C4; Be connected with the pulse width modulation module in the elementary winding electric of power frequency step-down transformer.
