Description
Technical field
The utility model relates to the power transmission shaft processing technique field, especially the power transmission shaft welding equipment.
Background technology
The structure of duplex power transmission shaft is that a front axle and a rear axle series connection are used.The position (all being positioned at the end of central siphon) that two places need weld before and after all having on front axle or the rear axle.The length of traditional alignment electric welding machine and the length of an axle are complementary, and body upper is provided with guide rail, and guide rail is provided with two cover running mechanisms, and each running mechanism is respectively equipped with a root bead rifle, can weld the position to be welded, two places on front axle or the rear axle simultaneously.Traditional power transmission shaft welding procedure is: 1. on extruder, push front axle and rear axle respectively and put in place.2. arrive the front axle assembly clamping that assembles with extruder above the alignment electric welding machine, carry out the alignment electric welding field.3. take off the good front axle of alignment, and then arrive the hind axle assembly clamping that assembles above the alignment electric welding machine, carry out the alignment electric welding field.4. manually couple together the front axle that assembles, rear axle with universal joint assembly.
Use traditional alignment electric welding machine, front axle and rear axle can satisfy the requirement of total run-out and weldquality respectively, but when two power transmission shaft butt joints, possibly just can not satisfy the requirement of total run-out.This is because the total run-out of front axle and the total run-out of rear axle possibly cancelled each other after butt joint, also possibly superpose mutually, when the mutual situation about superposeing of the total run-out of antero posterior axis occurs; The whole total run-out value of duplex power transmission shaft just exceeds requirement probably; Thereby influence the dynamic balancing of whole axle, cause the bad assurance of dynamic balancing of back operation, and entrucking forms resonance when using easily; Influence traffic safety, influence comfort level simultaneously.Traditional alignment electric welding field need the staff respectively clamping, unload front axle and rear axle, labour intensity is bigger, the staff who needs is more, efficient is low relatively.
The utility model content
The purpose of the utility model is to provide a kind of duplex power transmission shaft alignment electric welding machine that can solve above-mentioned prior art problem.
For realizing above-mentioned purpose; The duplex power transmission shaft alignment electric welding machine of the utility model comprises fuselage; The relative both sides of fuselage are respectively equipped with first tailstock and second tailstock; First tailstock is rotatably connected to rotating shaft through bearing, and the inner of rotating shaft is fixedly connected with axle sleeve, and the other end of axle sleeve is fixedly connected with the spline mandrel; Second tailstock is rotatably connected to back shaft through bearing, and back shaft is provided with the seam positioning disk, and waist is provided with carriage and the tray that is used to support the duplex power transmission shaft;
Said body upper is provided with guide rail, and guide rail is provided with the quadruplet running mechanism, and each running mechanism is respectively equipped with a root bead rifle.
Said guide rail is connected between the top of top and second tailstock of first tailstock.
The utility model is simple in structure, and is easy to use.Can once the property clamping be together on the duplex extruder with each parts of duplex power transmission shaft antero posterior axis during work; Need not repeated clamping can use the utility model that four contacts to be welded are carried out welding operation simultaneously after the alignment; Thereby eliminated in the past repeated clamping, positioning reference is different and error that bring increases phenomenon; The total run-out of the antero posterior axis of also having avoided in the past possibly occurring is the phenomenon of stack mutually, and the total run-out and the linearity that guarantee whole duplex power transmission shaft and then have improved dynamic balancing operation precision within the scope that requires; Vibration, noise of transmission system etc. have been reduced; Particularly have relatively high expectations for rotating speed, the Light-duty Vehicle of vibrating and noise is had relatively high expectations (light bus, commercial vehicle, picking-up vehicle, SUV or the like) is used the duplex power transmission shaft, the effect behind use the utility model is the most obvious.
