Abstract
The invention relates to an auxiliary locating tool for carrying out electric riveting and welding between an extra-large-size bearing strut and a retainer in the bearing industry, in particular to an adjustable electric riveting fixture for an extra-large-size bearing retainer, which is characterized by comprising a base, wherein the base is connected with a supporting plate (4) for placing a bearing to be welded through an inclined adjusting mechanism, thereby adjusting an angle of inclination of the bearing; the supporting plate (4) is respectively provided with an upper locating support (5), a left locating support (6) and a right locating support, and the three supports are all installed in a clamping slot in the supporting plate (4), thereby moving along the clamping slot to fix bearings of different sizes, wherein the upper locating support (5) is also connected with a lifting mechanism so as to move up and down. By adopting the fixture provided by the invention, the position of the bearing to be welded can be adjusted as required, thereby, an optimal electric riveting working position can be realized, not only burning internal assemblies by electrical sparks is reduced, but also deformation of a single-row tapered roller bearing, caused by the welding of the strut and the retainer, can be reduced.
Description
Technical field
The present invention relates in the bearing industry carrying out the assist location instrument of rivet weld welding usefulness, especially a kind of adjustable extra large size bearing retainer rivet weld jig between extra large size bearing pillar and the retainer.
Background technology
The rivet weld welding is that domestic bearing industry is to the most effective mode of solder technology of extra large size bearing pillar and retainer, but present this welding manner also is not generalized to the welding of taper roll bearing pillar and retainer, because this class bearing has tapering, and the tapering size is unfixing, and vary in diameter is big, the welding post of this class bearing of each specification is all different, so it is bigger that this class bearing is carried out rivet weld welding difficulty, the present domestic mode that the welding of such shaft column and retainer is mostly adopted arc welding, the retainer distortion is big, the size instability, often cause the side-sway of bearing overproof, again because arc welding easily produces electric spark, to the interior raceway in the inner assembly, the local generation of roller burnt, and seriously influenced the product quality of this class bearing.
Summary of the invention
The purpose of this invention is to provide a kind of adjustable extra large size bearing retainer rivet weld jig, position of bearings to be welded can be adjusted in a plurality of directions as required, thereby reach best rivet weld station.
For achieving the above object, the technical solution used in the present invention is:
A kind of adjustable extra large size bearing retainer rivet weld jig, its special feature is, comprise base, thereby being connected with the gripper shoe of placing bearing to be welded by a tilt adjusting mechanism, this base regulates the bearing inclination angle, be separately installed with positioning supports, left positioning supports and right positioning supports in this gripper shoe, thereby these 3 supports are installed in the draw-in groove on the gripper shoe and can move with the fixing bearing of different size along draw-in groove, also are connected with a hoisting mechanism and move up and down thereby wherein go up positioning supports.
Further, wherein hoisting mechanism adopts the lead screw pair that is installed on the gripper shoe.
Wherein tilt adjusting mechanism comprises the adjustment nut that is installed on the base, one leading screw passes behind this adjustment nut with between the gripper shoe and is connected by the ball rod oscillating bearing, thereby this gripper shoe is also by the hinged relative base rotation under the effect of leading screw of a plate and base.
Thereby wherein cooperate with guide rail on the rivet weld lathe and slide being provided with sliding-rail groove or pulley below the base.
Wherein on tilt adjusting mechanism and the hoisting mechanism handle is installed all.
Thereby it is rotatable that little bearing wherein is housed in last positioning supports.
Adopt jig of the present invention to adjust the position of bearing to be welded as required, thereby realize best rivet weld station, can reduce the burn of the internal assembly surface of electric spark, can reduce single-row tapered roller bearing again because the distortion that the welding of pillar and retainer causes, make this class bearing sideshake reach specification requirement, improve the product quality of this class bearing thus.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is the left view of Fig. 1.
The specific embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing:
As Fig. 1, shown in 2, the present invention includes base, thereby being connected with the gripper shoe 4 of placing bearing to be welded by a tilt adjusting mechanism, this base regulates the bearing inclination angle, be separately installed with positioning supports 5 in this gripper shoe 4, left side positioning supports 6, with right positioning supports, thereby being installed in the draw-in groove on the gripper shoe 4, these three supports can move to be applicable to the fixedly bearing to be welded of different size along draw-in groove, roughly 120 degree distributions at interval in same plane of these three supports, by the fixing bearing to be welded of three-point fix, thereby can tighten by securing member etc. after fixing and avoid mobile, thereby last positioning supports 5 wherein also is connected with a hoisting mechanism and moves up and down bearing to be welded.
As shown in Figure 1, hoisting mechanism adopts the lead screw pair that is installed on the gripper shoe 4, by the hoisting nut 3 that is fixed on the gripper shoe 4, passing the lifting leading screw 2 of hoisting nut 3 forms, promoting leading screw 2 lower ends is connected with last positioning supports 5 by connector 12, thereby can pass through positioning supports 5 in rotary handle 1 lifting, and then the heavier bearing to be welded of lifting.
And tilt adjusting mechanism comprises the adjustment nut 9 that is installed on the base, one leading screw 8 passes between this adjustment nut 9 and the gripper shoe 4 and is connected by the ball rod oscillating bearing, thereby this gripper shoe 4 is also by the hinged angle of inclination that can relative base under the effect of leading screw 8 rotates to adjust bearing to be welded of a plate 11 and base.
As shown in Figure 1, 2, thus can cooperate with the guide rail 10 on the rivet weld lathe and slide being provided with sliding-rail groove or pulley below the base.
Rivet weld jig of the present invention is installed on the rivet weld lathe when using, the rivet weld lathe has 2 dies, and (left end is fixing head, right-hand member is the moving head by hydraulic mechanism control), when optimal rivet weld station is transferred to the conical bearing position by the rivet weld jig, the control bottom right rivet weld head of hydraulic system left the worker proceed to pillar, the operator realizes the rivet weld welding to pillar and retainer by the energising of operation knob.
