Description
Technical field
The present invention relates to a kind of end surface clamp for motor case vehicle, belong to the technical field of motor manufacturing and processing equipment.
Technical background
For guaranteeing closely cooperating between motor case and the end cap, all need usually two end faces of casing are machined, the three-jaw chucks of lathe that adopt are clamped on the casing outer wall more in the prior art, the casing end are machined again.Yet casing is a cylinder-like structure all generally, and in the course of processing, three-jaw chuck may cause the casing distortion, thereby has influenced the crudy of casing.
Summary of the invention
The object of the invention is to provide a kind of convenient mounting and clamping, can not cause the casing distortion, can guarantee the end surface clamp for motor case vehicle of the crudy of casing, solved that prior art exists in the course of processing, three-jaw chuck may cause the casing distortion, thereby has influenced the problems such as crudy of casing.
Above-mentioned technical purpose of the present invention mainly solves by the following technical programs: it comprises the supporting seat that is hollow and is engaged in the interior tension shaft of hollow structure of supporting seat, described supporting seat one end forms the cylindrical portion of one with it, offer at least two along the circumferential direction equally distributed watt of shape openings on the barrel of described cylindrical portion, be combined with a watt shape slide block in described each watt shape opening, described watt of shape slide block inwall is the big arc internal conical surface in inner little outer end, described arc internal conical surface is coaxial with tension shaft, described tension shaft is an awl section corresponding to the cylindrical portion position, described awl section outer surface forms and watt outer conical surface that shape slide block inwall cooperates, when tension shaft and supporting seat move to axial, watt shape slide block will move radially in watt shape opening.Before the clamping, the awl section outer conical surface of tension shaft and the arc internal conical surface of watt shape slide block certain distance that axially staggers, promptly awl section outer conical surface also not exclusively cooperates with the arc internal conical surface of watt shape slide block, thereby the outer surface of watt shape slide block and the cylindrical outer wall of supporting seat are on the same face of cylinder substantially, the external diameter of the common external cylindrical surface that constitutes of watt shape slide block and supporting seat cylindrical portion is less than the internal diameter for the treatment of the clamping casing, at this moment, casing can be placed in outside the tubular position of supporting seat like a cork; After casing is placed in outside the tubular position of supporting seat, tension shaft and supporting seat are moved to axial, even the awl section outer conical surface on the tension shaft cooperates fully with the arc internal conical surface of watt shape slide block, thereby the outer surface of watt shape slide block is protruded from the outer wall of supporting seat cylindrical portion, watt outer surface of shape slide block and casing inner wall are combined together tightly, casing promptly is positioned in the present invention reliably, can the outer end of casing be machined; After the completion of processing, make the axial motion in the opposite direction of tension shaft and supporting seat, making a watt shape slide block return to the home position can take off the workpiece that processes easily.Because the mode of tensioner was carried out clamping and positioning to casing in the present invention adopted, can prevent that clamp operation from causing the crimp to casing, thereby guarantee the crudy of casing that the operation of clamping operation and dismounting workpiece is also very convenient.
