Abstract
The utility model provides a special-purposed testing fixture for a main-shaft HSK joint. The testing fixture comprises a workpiece, wherein a testing mandrel is arranged in an inner hole of a main shaft of the workpiece, a positioning guide sleeve is arranged at the rear end of the testing mandrel, locking nuts are arranged on the positioning guide sleeve, a gauge calibration ring is arranged at the right end surface of the workpiece, the gauge calibration ring is fixedly connected with a gauge seat via screws, a handle is mounted at the lower end of the gauge calibration ring, and a dial gauge is arranged on the gauge seat; and the positioning guide sleeve is tightly applied to an inner taper hole at the front end of the main shaft of the workpiece. The testing fixture is simple in structure, easy to operate and low in cost, and greatly reduces the production cost of the HSK main shaft.
Description
Technical field
The utility model belongs to mechanical field, relates in particular to a kind of HSK main shaft interface appliance special for detecting.
Background technology
At present in cut field, the main shaft of HSK interface is more and more general, and HSK is a kind of hollow short taper shank interface, and it adopts two location (endoporus and end face) to coordinate with main shaft, so it is quite strict to main shaft end face location dimension (56 ± 0.023) to 30 ° of inner conical surfaces, sees Fig. 1.
Processing this class main shaft key is cubing (measuring 56 ± 0.023), the structure of external cubing a: gauge head with digital display, an axle with 30 ° of male cone (strobilus masculinus)s is installed in the middle of gauge head, mounting spring in axle, during measurement, the button of gauge head top is gone out downwards deeply by lower spindle, now cubing is goed deep into tested inner hole of spindle, one end face of gauge head abuts on main shaft end face, release button, axle makes 30 ° of male cone (strobilus masculinus)s and the laminating of main shaft inner conical surface under the acting force of spring, now on digital display meter, just can read the numerical value of measured data.The cubing of HSK main shaft interface is domestic does not also have producer to make at present, can only dependence on import, and the HSK interface appliance special for detecting of a set of 80 models of import approximately needs ten thousand yuans of 15-18, expensive, in HSK main shaft advanced development, has increased manufacturing cost.
Summary of the invention
The utility model provides a kind of HSK main shaft interface appliance special for detecting, has solved the external expensive shortcoming of cubing in background technology.
The technical solution of the utility model is achieved in that a kind of HSK main shaft interface appliance special for detecting, comprise workpiece, in the inner hole of spindle of workpiece, be provided with measurement axle, measure mandrels backend and be provided with positioning and guiding cover, positioning and guiding puts and is provided with set nut, and workpiece right side is provided with his-and-hers watches ring, and his-and-hers watches ring is fixedly connected with gauge stand by screw, his-and-hers watches ring lower end is equipped with handle, and gauge stand is provided with dial gauge;
Positioning and guiding cover fits tightly with the internal taper hole of work spindle front end.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to operate, and cheap, greatly reduce the production cost of HSK main shaft.
Accompanying drawing explanation
Fig. 1 is HSK main shaft interface schematic diagram;
Fig. 2 is structural representation of the present utility model.
Part explanation: 1, measure axle, 2, positioning and guiding cover, 3, set nut, 4, his-and-hers watches ring, 5, screw, 6, gauge stand, 7, dial gauge, 8, handle, 9, workpiece, 10, measure 30 ° of male cone (strobilus masculinus)s of axle, 11,30 ° of inner conical surfaces of main shaft.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: a kind of HSK main shaft interface appliance special for detecting, by measuring axle 1, put in the endoporus of positioning and guiding cover 2, again the endoporus of measuring axle 1 and positioning and guiding cover 2 and together put into tested main shaft, together with positioning and guiding cover 2 fits tightly with the internal taper hole of front-end of spindle 1:10, play fixation, now measuring axle 1 can only overlap in 2 endoporus and move left and right at positioning and guiding, measure axle 1 front end and have screw thread, set nut 3 is screwed, drive measurement axle 1 to be moved to the left, until measure 30 ° of male cone (strobilus masculinus)s 10 of axle 1 fit tightly with 30 ° of inner conical surfaces 11 in inner hole of spindle together with till, be close to the difference of right side and workpiece 9 right sides of rear measurement axle 1, handle 8 and gauge stand 6 are installed on his-and-hers watches ring 4, on gauge stand 6, install with dial gauge 7, before measurement, first his-and-hers watches ring 4 and assembly above thereof are placed on platform dial gauge 7 calibration zero-bits, be arranged on the handle 8 on his-and-hers watches ring 4, the right side of the left side of his-and-hers watches ring 4 and workpiece 9 is fitted tightly, the gauge head of dial gauge 7 is pressed on the right side of measuring axle 1, now just can read and measure the right side of axle 1 and the difference of workpiece 9 right sides whether within the scope of ± 0.023mm from dial gauge 7, because measure 30 ° of male cone (strobilus masculinus)s of axle 1 to position, the right side 56mm that measures axle 1, as long as so while measuring, see the no left and right in zero-bit of pointer hand on dial gauge 7 ± change in 0.023mm, by such device, just can detect 30 ° of inner conical surfaces to main shaft end face location dimension (56 ± 0.023), reduce production costs.
