Utility model content
Technical problem to be solved in the utility model is, the casing retaining mechanism in a kind of motor case drilling equipment is provided, and it can take off the casing machining in the situation that locking nut not being screwed off.
For solving the problems of the technologies described above, casing retaining mechanism in the motor case drilling equipment that the utility model provides, it comprises that one for being nested with the sleeve part of casing, on the end face of this sleeve part, be provided with a tight lock part, this tight lock part comprises that one is arranged on locking bed and the clamping screw on the end face of sleeve part, locking bed is pegged graft and is coordinated for the centre bore with bottom of shell, between described clamping screw and locking bed, be provided with a latch, the threaded shank of clamping screw through latch and with locking bed on screwed hole threaded engagement, the head of clamping screw and latch offset so that latch is pressed on casing on sleeve part, on described latch, offer the breach for the threaded shank through clamping screw, the external diameter of the head of described clamping screw is less than the aperture of centre bore of the bottom of casing.
Adopt after above structure, the utility model compared with prior art, has advantages of following:
After processing casing, only clamping screw need to be unscrewed a little, then latch is taken off, the centre bore of casing can be slipped over and casing is taken off from clamping screw, like this, make can take off casing in the situation that not needing clamping screw to screw off, more for convenience, and clamping screw is difficult for losing.
As improvement, described sleeve part comprises cylindrical the first sleeve part and is the second round table-like sleeve part, one end larger with the diameter of the second sleeve part, one end of the first sleeve part is fixedly connected with, and locking bed is arranged on less one end of diameter of the second sleeve part.Like this, the first sleeve part coordinates with the first perisporium of casing, the second sleeve part coordinates with the second perisporium of casing, after casing is nested with on sleeve part, the first perisporium of casing is nested with and is fixed on the first sleeve part, the diapire of casing and the end face of the second sleeve part offset simultaneously, make casing fixing firm.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
By Fig. 2, shown in Fig. 3, casing retaining mechanism in the utility model motor case drilling equipment comprises that one for being nested with the sleeve part 3 of casing, on the end face of this sleeve part 3, be provided with a tight lock part, this tight lock part comprises that one is arranged on locking bed 4 and the clamping screw 5 on the end face of sleeve part 3, locking bed 4 is pegged graft and is coordinated for the centre bore with bottom of shell, it is characterized in that: between described clamping screw 5 and locking bed 4, be provided with a latch 6, the threaded shank 502 of clamping screw 5 through latch 6 and with locking bed 4 on screwed hole 401 threaded engagement, head 501 and the latch 6 of clamping screw 5 offset so that latch 8 is pressed on casing on sleeve part 3, on described latch 6, offer the breach 601 for the threaded shank 502 through clamping screw 5, the external diameter of the head 501 of described clamping screw 5 is less than the aperture of centre bore of the bottom of casing.
Described sleeve part comprises cylindrical the first sleeve part 302 and is the second round table-like sleeve part 301, one end larger with the diameter of the second sleeve part 301, one end of the first sleeve part 302 is fixedly connected with, and locking bed 4 is arranged on less one end of diameter of the second sleeve part 301.
During processing casing, first casing to be processed is nested with on sleeve part 3, the first perisporium of casing is nested with and is fixed on the first sleeve part 302, the end face of the diapire of casing and the second sleeve part 301 offsets, now locking bed 4 is inserted into the centre bore on the diapire of casing, then the threaded shank of clamping screw 5 502 is screwed on the screwed hole 401 on locking bed 4, then latch 6 is inserted into the threaded shank 502 of clamping screw 5 by breach 601, make latch 6 between the head 501 and the diapire of casing of clamping screw 5, then screw locking nut 5, the head 501 of locking nut 5 is pressed on latch 6 on the diapire of casing, so just by locking nut 5, casing is locked, then the mount pad on casing is holed.
After boring completes, then the threaded shank of locking nut 5 502 is screwed out a little from the screwed hole 401 of mount pad 4, unnecessary locking nut 5 is taken off, as long as now latch 6 can be extracted between the head 501 of locking nut 5 and the diapire of casing, then latch 6 is extracted between the head 501 of locking nut 5 and the diapire of casing, now due to the aperture of the centre bore on the diapire of casing, be greater than the external diameter of the head 501 of locking nut 5, now casing directly can be taken off, soon the centre bore on the diapire of casing skids off from locking nut 5, like this, in the situation that not needing to take off locking nut 5, can lock and take off casing, like this, do not need precession frequently and screw out locking nut 5, more for convenience, and locking nut 5 is connected on mount pad 4 always, locking nut 5 is not easy to lose.
Below only with regard to the utility model, apply preferably example and made explanation, but can not be interpreted as it is limitations on claims, structure of the present utility model can have other to change, and is not limited to said structure.In a word, all various variations of doing in the protection domain of independent claims of the present utility model are all in protection domain of the present utility model.
