Detailed Description

The invention is further described with reference to the following specific drawings and examples.

As shown in fig. 1-4, a tooling for a motor stator and rotor punching die adjustable roller frame comprises a repairing chassis 6 and roller frames 5 which are symmetrically arranged on the upper surface of the chassis 6 and used for supporting a workpiece, wherein the chassis is of a hollow structure and comprises two layers of frame bodies which are arranged in parallel, a speed reducer 21 is arranged on the frame body on the lower layer, a reversing switch 22 is arranged on the side edge of the frame body on the upper layer, two roller frames 5 which are symmetrically distributed are arranged on the upper surface of the frame body on the upper layer, the bottoms of the roller frames 5 are movably arranged in a chassis panel waist groove 18 formed in the repairing chassis 6, rollers 4 are arranged on the roller frames, the two rollers 4 are supported on the lower part of the workpiece, a pressing plate 2 and a channel steel 3 are respectively arranged in the front and at the back of the center of the roller frames, the workpiece is respectively pressed against the front and back through the pressing plate 2 and the channel steel 3, a roller 12 is arranged on the, the two ends of the excircle of the rolling shaft are provided with rolling bearings 10, the rolling bearings 10 are assembled with a chain wheel 16, the excircle of the chain wheel 16 is assembled at one end of an annular chain 20, and the other end of the annular chain 20 is assembled on an output shaft of the speed reducer.

As a further improvement, the pressing plate 2, the channel-section steel 3 and the workpiece are fixedly pressed by the bolt 7, the thickening nut 8 and the flat washer 9.

As a further improvement of the utility model, the roller frame outer cover is provided with a chain wheel cover 19.

As a further improvement of the utility model, the roller 4 is a rubber roller.

As a further improvement of the present invention, a circlip 11 for hole is provided between the rolling bearing 10 and the roller 12.

The utility model discloses the adjustable frock design who repairs electronic roll frame of motor stator and rotor punching die, concrete theory of operation as follows:

firstly, assembling all parts according to the figures 1 and 2, and assembling a rubber roller 4; a rolling bearing 10; an elastic retainer ring 11 for a hole; the roller 12 and the like are assembled into a whole according to the requirement of the drawing, are arranged in the roller frame opening groove 5 and fixed, are assembled on the underframe panel waist groove 18 and are fixed on the repair underframe 6 by the fastener 13 (the fastener comprises a hexagon bolt, a nut and an elastic cushion) according to the diameter phi D of the workpiece 1.

The principle that the workpiece 1 can be easily rotated (the rolling friction coefficient is small) is utilized, and the two rubber rollers 4 (one of which is an active wear-resistant rubber roller and the other one of which is a passive wear-resistant rubber roller) below the workpiece can be electrically operated.

In specific operation, a die (i.e. a workpiece 1) to be repaired is hung between two rollers by a crane (as shown in the figure). The stud bolts 7 are used; thickening the nut 8; the flat washer 9 and the pressure plate 2 can be repaired after being fixed according to the repair needed direction, if the position needs to be changed, the position is electrically transmitted to the driving rubber roller 4 and the driven rubber roller 4 through the annular chain 20 and the upper and lower chain wheels 16 of the speed reducer 21, and the purpose of rotating the workpiece (capable of rotating forward and backward) is achieved. After the operation is finished, the thickened nut 8 is loosened by a special solid wrench, the pressing plate 2 is taken down, and the chassis 6 is repaired by hanging the crane.

Because the movable active and passive rubber rollers 4 assembled by the rolling bearings 10 are designed, the surface quality of the workpiece is protected from being influenced in the processes of repairing, rotating and the like of the whole workpiece, and the process is very easy and flexible. The repair underframe 6 is also provided with an underframe panel waist groove 18, so that the center distance between the 4 rollers can be adjusted within a certain range, and the repair range is enlarged.

And because the steel ruler 17 with scales is arranged on the surface of the repair underframe 6, and the steel ruler 17 and the side surface of the waist groove 18 are arranged side by side with each other, the quick positioning can be realized when the center distance between the two rollers is adjusted. The roller adjustment time is greatly shortened. The preparation work before repair can be quickly and smoothly realized. The channel steel and the 6-repair underframe are directly and firmly welded, so that the device has reliable safety and the like. Therefore, the labor is saved, and the repairing process of the workpiece is rapid, convenient and safe.

Finally, it should be noted that: the above embodiments are only used for illustrating the technical solution of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
