Fig. 1 is the structural representation that the utility model lathe spindle is used the quick clamping device specific embodiment;
Fig. 2 is the structural representation of overcoat among Fig. 1;
Fig. 3 is the structural representation of Fig. 1 Elastic cover;
Fig. 4 is the A-A cutaway view among Fig. 1.
The specific embodiment
Lathe spindle of the present utility model is with the implementation of quick clamping device for example Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, and this quick clamping device is mainly by the overcoat 1 that is used for cooperating with lathe chuck 5 clampings and slide to be plugged in the overcoat 1 and form for the resilient sleeve 2 that clamps axial workpiece 6 leading sections to be processed.The front end of overcoat 1 is for being used for the clamping part with lathe chuck 5 clamping engagement, the rear end face center of overcoat 1 offers the centre bore 10 that axially extends forward, and this centre bore 10 forms from backward front diminishing taper hole section 101 and cylindrical hole section 102 one of being located at one heart taper hole section 101 miner diameter ends by being positioned at place, aperture, rear end internal diameter.In resilient sleeve 2 slip plug-in mountings and this centre bore 10, the rear end face central shaft of this resilient sleeve 2 to offer for the axial workpiece 6 to be processed jack 21 that sleeves cooperate that coincide, the outer peripheral face of this resilient sleeve 2 be provided with external diameter by rear to front cooperate with these taper hole section 101 internal faces when dwindling gradually, being subjected under the External Force Acting to move along centre bore 10 to taper hole section 101 miner diameter ends realization radially actuate, to clamp the frusto-conical face 20 of axial workpiece 6 leading sections to be processed.Between overcoat 1 and resilient sleeve 2, also be top-loaded with and order about the backward mobile elastic component that resets of resilient sleeve 2.In the present embodiment, resilient sleeve 2 integral body are truncated conical configuration, it is used for coincideing jack 21 that sleeves cooperate for being used for and the spacing blind hole that cooperates of axial workpiece 6 blocks to be processed with axial workpiece 6 to be processed, is laid with some axially towards the openings 23 of the place ahead extension around the circle spacing at the anchor ring of the bigger diameter end of resilient sleeve 2; The centre bore 10 of overcoat 1 is blind hole, and the elastic component that is mounted between overcoat 1 and the resilient sleeve 2 is the cylindrical compression spring 3 that is provided with in the centre bore 10 cylindrical hole sections 102.
Lathe spindle of the present utility model is mainly used in the Machining of Shaft-type Parts that two ends offer center positioning hole with quick clamping device.During use, overcoat 1 is fixedly clamped on lathe chuck 5 by its front end clamping part, resilient sleeve 2 is inserted in the centre bore 10 of overcoat 1 rear end, the front end of axial workpiece 6 to be processed is inserted in the jack 21 of resilient sleeve 2 rear ends, the center positioning hole that the rear end of axial workpiece 6 to be processed drills through by its end face center holds out against with the top location of tail stock 7, tail stock 7 is when holding out against axial workpiece 6 to be processed, promote to move forward behind the elastic force that resilient sleeve 2 overcome cylindrical compression spring 3 by axial workpiece to be processed 6, slip in the centre bore 10 of overcoat 1, resilient sleeve 2 cooperates with taper hole section 101 in the centre bore 10 by its surperficial frusto-conical face 20 makes resilient sleeve 2 produce radial contraction, thereby clamp axial workpiece 6 to be processed, realize that the clamping of axial workpiece 6 to be processed fixes, after the completion of processing, withdraw from tail stock, cylindrical compression spring 3 promotes the centre bore 10 that resilient sleeve 2 is stretched out overcoat 1 backward by self elastic force, realization resets, resilient sleeve 2 this self elasticity is opened, the axial workpiece that processes can be extracted, insert follow-up axial workpiece to be processed.This quick clamping device is simple in structure, easy to use, has accelerated greatly lathe clamping speed, has improved the working (machining) efficiency of lathe, and has effectively lowered the labour intensity of turner, is applicable to the lathe processing in enormous quantities of same axis products.
