Abstract

The utility model discloses a clamp for machining the thickness excircle surface of a spherical shell, mainly comprising a front-end locating device and a rear centre, wherein the front-end locating device is composed of a fastener, an adjusting sleeve, a spring, a movable mandrel and a Morse taper sleeve; a through hole matched with the movable mandrel is formed in the centre of the Morse taper sleeve; the rear end of the movable mandrel is smaller than the front end thereof, and the formed step is a fixed seat for the spring; the tail end of the movable mandrel is a screw rod matched with the fastener; the movable mandrel is installed in the Morse taper sleeve, and then the spring and the adjusting sleeve are installed from the tail end and fixed by the fastener to form the front-end locating device; the shape of the upper surface of the movable mandrel is a spherical surface matched with the shape of the outwards-projected surface of the to-be-machined component; the distance between the lowest end of the spherical surface of the movable mandrel and the upper surface of the Morse taper sleeve is equal to or greater than the distance between the locating surface of the to-be-machined component and the top end of the outwards-projected spherical surface of the to-be-machined component; the rear centre is composed of a centre sleeve and a centre head; and the shape of the centre head is a spherical surface which is the same as the inner surface of the to-be-machined component. With the adoption of the clamp, the problems of clamping and centring of spherical workpieces are effectively solved.

Description

The fixture of processing spherical shell thickness periphery
Technical field
The utility model belongs to the fixture of machining, especially belongs to the fixture that meets spherical shell thickness periphery processing request.
Background technology
Engine lathe is top because centering precision is high, in the working shaft-like part, is used widely.But the workpiece to sphere and plane combination can't accurately be felt relieved, and causes the clamping workpiece difficulty, machining accuracy is difficult to guarantee.
Summary of the invention
The utility model purpose is to overcome the shortcoming existed in above-mentioned machining, and a kind of convenient mounting and clamping, accurately centering are provided, and machining accuracy can meet the requirements of the fixture of processing spherical shell thickness periphery.
The technical scheme that the utility model adopts is a kind of fixture of processing spherical shell thickness periphery, its main points are, it mainly comprises front lay and back centre, described front lay is by securing member, regulating sleeve, spring, movable mandrel, mohs bush forms, the mohs bush center has the through hole matched with movable mandrel, the rear end of movable mandrel is less than front end, the holder that formed step is spring, the screw rod of the tail end of movable mandrel for matching with securing member, movable mandrel is packed mohs bush into again from the tail end spring of packing into, regulating sleeve, with the fixing front lay that forms of securing member, being shaped as and the part to be processed sphere that the convex surface shape matches outward of movable mandrel upper surface, distance between movable mandrel sphere lowermost end and mohs bush upper surface equals greatly the top distance of the locating surface of part to be processed to part evagination sphere to be processed, back centre is comprised of center sleeve and centre head, centre head be shaped as the sphere identical with accessory inner surface to be processed.
The utility model effectively solves clamping and the centering problem of sphere workpiece, be particularly useful for batch production, utilize the utility model that spherical shell is put into to front lay, because movable mandrel surface is to match with the spherical shell surface, thereby reach the purpose of quick location, inner surface configuration due to centre head and spherical shell matches simultaneously, when centre head is moved to the left compression, centre head, the front end face of the locating hole of spherical shell and mohs bush is combined closely, reach spherical shell is located, compress so that the purpose that end face processing can be carried out smoothly, certain reference role to being designed with of similar revolving body clamp for machining.
The accompanying drawing explanation
The use view that Fig. 1 is the utility model embodiment 1
Wherein: 1 securing member 3 regulating sleeve movable mandrel 51 fabrication hole 6 mohs bush 61 through hole 7 back centre 71 center sleeve 72 centre head 8 of 4 spring 5 part A to be processed is to be processed.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can makes the professional and technical personnel more understand the utility model, following embodiment is modified, it is all possible adding and replacing, and does not all exceed protection domain of the present utility model.
As Fig. 1, shown in 2, a kind of fixture of processing spherical shell thickness periphery, it mainly comprises front lay and back centre 7, described front lay is by securing member 1, regulating sleeve 3, spring 4, movable mandrel 5, mohs bush 6 forms, mohs bush 6 centers have the through hole 61 matched with movable mandrel 5, the rear end of movable mandrel 5 is less than front end, the holder that formed step is spring 4, the screw rod of the tail end of movable mandrel 5 for matching with securing member 1, movable mandrel 5 is packed mohs bush 6 into again from the tail end spring 4 of packing into, regulating sleeve 3, with the fixing front lay that forms of securing member 1, being shaped as and the part to be processed sphere that the convex surface shape matches outward of movable mandrel 5 upper surfaces, in figure, fabrication hole 51 stays in order to process movable mandrel outer face, distance between movable mandrel 5 sphere lowermost ends and mohs bush 6 upper surfaces equals greatly the top distance of the locating surface of part to be processed to part evagination sphere to be processed, back centre 7 is comprised of center sleeve 71 and centre head 72, centre head 72 be shaped as the sphere identical with accessory inner surface to be processed.
By being nut, packing ring in securing member 1(figure) and the work strength of regulating sleeve 3 regulating springs 4.In process, part 8 to be processed packs into the sphere of movable mandrel, centre head 72 is moved to the left, promote part to be processed and movable mandrel 5 is moved to the left, until the end face of part to be processed is adjacent to the end face of mohs bush 6, complete the centering of workpiece, fixedly front lay and back centre 7 are treated processing parts 8 and are fixed and just can treat machined surface A and processed.
