Abstract
The utility model discloses a tapered-hole machining mechanism. The tapered-hole machining mechanism comprises a carrier (1) and a clamp (11), wherein the clamp (11) is fixed on the carrier (1) and comprises a semi-circular-arc concave groove seat (10), a semi-circular-arc top cover (4) and an elastic hole (6) connecting the concave groove seat (10) and the top cover (4), and a clamping device is arranged at the other end of the top cover (4) and used for clamping the top cover (4) and the concave groove seat (10). The tapered-hole machining mechanism is simple in structure, novel in design, simple and convenient to operate, and accurate in positioning, and the clamp clamps a workpiece stably and firmly and is high in machining accuracy.
Description
Technical field
The utility model relates to field of machining, is a kind of raising the efficiency and the taper hole organisation of working of precision specifically.
Background technology
In the manufacture process of machine tool chief axis, electric machine main shaft, require the outer steps of axle, comprise bearing erecting bed, gear drive platform, rotor platform, the concentricity certain with the taper hole maintenance of axle front end.Before the processing taper hole, use cylindrical grinder that all outer steps are worked into drawing requirement size.Then with lathe with the rough turn shaping of the taper hole of front end (reserve mill processing capacity).
Common boring grinding machine uses the two ends of two V font cushion block back shafts usually when grinding taper hole, re-use the upper end that a malthoid is pushed down axle.In the process of grinding, there are the following problems, the 1:V font cushion block pillow block that can wear and tear; 2: the material of malthoid is very soft, and axle has vibration in rotation process, reduces machining accuracy; 3: if press tension, the wearing and tearing meeting of pillow block is very serious.Therefore cause the adjustment time of processing long, precision can't guarantee.
The utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model provides a kind of taper hole organisation of working, has solved the not high problem of existing boring grinding machine precision.
(2) technical scheme
For solving the problems of the technologies described above, technical scheme that the utility model adopts is: a kind of taper hole organisation of working, comprise carriage (1), anchor clamps (11), described anchor clamps (11) are fixed on the described carriage (1), described anchor clamps (11) comprise semicircular arc groove seat (10), semicircular arc top cover (4) and connect described groove seat (10) and the springhole (6) of top cover (4) one ends that described top cover (4) other end is provided with clamping device and is used for described top cover (4) and described groove seat (10) are clamped.
Described clamping device comprises that first screw (3) and described top cover (4) go up the through hole (9) that the end away from springhole (6) arranges, and described first screw (3) passes described through hole (9) and is connected on the end face of described groove seat (10).
Also comprise pressing plate (2), described pressing plate (2) one ends are fixed on the described carriage (1), and described pressing plate (2) other end is pushed down described groove seat (10) edge and is fastenedly connected on described carriage (1) with second screw (12).
Described carriage (1) is provided with two groups and be installed on the guideway of grinding machine.
(3) beneficial effect
The utility model is compared to prior art, and have following beneficial effect: it is simple in structure, and modern design is easy and simple to handle, accurate positioning, and anchor clamps to clamp workpiece steadily firm, the machining accuracy height.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the state diagram that adds man-hour of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of taper hole organisation of working, comprise carriage 1, anchor clamps 11, anchor clamps 11 are fixed on the carriage 1, anchor clamps 11 comprise semicircular arc groove seat 10, semicircular arc top cover 4 and connect the springhole 6 of groove seat 10 and top cover 4 one ends that top cover 4 other ends are provided with clamping device and are used for top cover 4 and groove seat 10 are clamped.Clamping device comprises on first screw 3 and the top cover 4 that through hole 9, the first screws 3 that the end away from springhole 6 arranges pass on the end face that through hole 9 is connected in groove seat 10.Also comprise pressing plate 2, pressing plate 2 one ends are fixed on the carriage 1, and pressing plate 2 other ends are pushed down groove seat 10 edges and are fastenedly connected on carriage 1 with second screw 12.
As shown in Figure 2, carriage 1 is provided with two groups and be installed on the guideway of grinding machine.
Use endoporus grinding machine processing taper hole, the mechanism that the present invention is designed is fixed on the guide rail of grinding machine, bearing 5 is placed at two ends at processing axle 13, to process the bearing of installing on the axle 13 5 then is fixed in the anchor clamps 11, use first screw 3 to compress the outer ring of bearing 5, because the effect of springhole 6, bearing 5 is fully fixed.
Use the center line (this process only need carried out in the processing for the first time, and all the other identical workpiece need not repeat) of amesdial centering processing axle 13.The tailstock case of use grinding machine makes stirs dish 8 rotations, and the feed mechanism of use grinding machine will grind emery wheel 7 and enter in the taper hole that needs to process, and start emery wheel 7, processing axle 13 and emery wheel 7 be produced relative rotation can begin to grind.After grinding the size of needs, unclamp first screw 3, because the effect of springhole 6, anchor clamps unclamp bearing 5, have finished required processing.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
