Description
Technical field
The utility model relates to the frock field of processing motor cabinet, specifically a kind of interior swelling positioning tool processing motor cabinet.
Background technology
At present, the cross structure that direct current square motor support turning tool adopts, outside dimension is fixed, and can not move radially, by two side guide compacting machine seats; For the ease of clamping during turning, frock outside dimension and support internal diameter size must adopt matched in clearance.In use, owing to adopting matched in clearance, the axiality of the support front and back end seam causing turnery processing good and support iron core shelves is difficult to ensure.And its fit clearance of Long-Time Service can be increasing, coaxiality error is also increasing, finally causes the electric machine rotor assembled to be wiped mutually, and even directly locking, has a strong impact on motor quality.
Existing direct current generator square engine base turning tool is made up of mandrel, clamp nut, jacking block and end platen, jacking block is fixedly connected on mandrel, the square motor support of so genuine different size then needs the jacking block formulating specific standard, adds cost of manufacture.The dismounting of end platen is cumbersome simultaneously, consumes artificial many, the shortcomings such as adjustment inaccuracy.
Utility model content
The purpose of this utility model is to provide a kind of interior swelling positioning tool processing motor cabinet, solves processing processing square electric support and improves the problem adding the axiality in man-hour.
The technical solution of the utility model is as follows:
A kind of interior swelling positioning tool processing motor cabinet, comprise mandrel and clamp nut, it is characterized in that: the leading portion of described mandrel is provided with external screw thread, described clamp nut is connected to the leading portion of described mandrel by threaded engagement, the stage casing of described mandrel is circumferentially with expanding structure in many groups, in described many groups, expanding structure has included width muscle, slide block and guide pad, described width muscle is fixed on the stage casing of described mandrel, described guide pad is between described width muscle and slide block, and be fixedly connected on described width muscle, the bottom of described slide block is provided with the chute be slidably matched with described guide pad, the front end of slide block is installed with the buckling piece withheld on described clamp nut.
The interior swelling positioning tool of described processing motor cabinet, is characterized in that: described width muscle has gradient, and is fixed in the groove offered in described mandrel stage casing.
The interior swelling positioning tool of described processing motor cabinet, is characterized in that: described slide block is rectangular configuration, and the bottom surface of slide block is inclined-plane.
The interior swelling positioning tool of described processing motor cabinet, is characterized in that: described guide pad is trapezium structure, and is fixedly connected with described width muscle by set bolt.
The interior swelling positioning tool of described processing motor cabinet, is characterized in that: described slide block is that solid or slide block are provided with multiple hollow out lattice in the middle.
The beneficial effects of the utility model:
The utility model structure is simple, and easy to operate, working (machining) efficiency is high, applied widely, and stock utilization is high, improves the axiality at square cross two ends seam and center, and then improves the quality of parts.
Accompanying drawing explanation
Fig. 1 is the utility model structure sectional view.
Fig. 2 is the utility model structural blast figure.
Detailed description of the invention
See Fig. 1, 2, a kind of interior swelling positioning tool processing motor cabinet, comprise mandrel 1 and clamp nut 2, the leading portion of mandrel 1 is provided with external screw thread 3, clamp nut 2 is connected to the leading portion of mandrel 1 by threaded engagement, the stage casing of mandrel 1 is circumferentially with expanding structure in many groups, in many groups, expanding structure has included width muscle 4, slide block 5 and guide pad 6, width muscle 4 is fixed on the stage casing of mandrel 1, guide pad 6 is between width muscle 4 and slide block 5, and be fixedly connected on width muscle 4, the bottom of slide block 5 is provided with the chute 10 be slidably matched with guide pad 6, the front end of slide block 5 is installed with the buckling piece 7 withheld on clamp nut 2.
In the utility model, width muscle 4 has gradient, and is fixed in the groove 8 offered in mandrel 1 stage casing.
Slide block 5 is rectangular configuration, and the bottom surface of slide block 5 is inclined-plane.
Guide pad 6 is trapezium structure, and is fixedly connected with width muscle 4 by set bolt 9.
Slide block 5 is solid, or slide block 5 is provided with multiple hollow out lattice 11 in the middle, with weight reduction and saving material.
Below in conjunction with accompanying drawing, the utility model is further described:
Slide block 5 is arranged on the width muscle 4 of band gradient by guide pad 6 by the utility model, regulates clamp nut 2, slide block 5 is produced at width muscle 4 and slides axially, and produce equal radial displacement, thus reach swelling support and the object of automatic centering expansion motor cabinet 12.This structure has convenient mounting and clamping, feature simple to operate compared with turning tool of the prior art, and axiality improves nearly four times than original structure.In addition, the auto-lock function of clamp nut 2, after compaction with in turning process, can not produce skew.And for the square cross of the different length of side, only need change the slide block of differing heights, other parts are reusable, a large amount of process times and raising stock utilization can be saved.
The foregoing is only preferred embodiment of the present utility model, all equalization changes done according to the utility model right, all should belong to the covering scope of the utility model claim.
