Between described overcoat and resilient sleeve, also be top-loaded be used to ordering about the backward mobile elastic component that resets of resilient sleeve.
Described centre bore is blind hole, in this centre bore, be positioned at taper hole section miner diameter end also coaxial extension be provided with the cylindrical hole section, described elastic component is the cylindrical compression spring of being located in the cylindrical hole section.
Described resilient sleeve integral body is frusto-conical configuration, is laid with some axially extended openings at the end face of resilient sleeve bigger diameter end around the circle spacing.
Place, blind hole aperture at described tail cover also is provided with taper hole shape guide frame.
Axle of the present utility model cooperates with tail stock in use with the lathe quick clamping device, end with axial workpiece to be processed during use inserts resilient sleeve, the other end inserts in the tail cover, tail is enclosed within the tail stock drive and slides in the centre bore of overcoat by axial workpiece promotion resilient sleeve to be processed, the butt annular conical surface of resilient sleeve by its outer peripheral face cooperates with the taper hole section of overcoat centre bore to be made resilient sleeve produce radial contraction to clamp axial workpiece to be processed, realize clamping the quick-clamping of axial workpiece to be processed on lathe, this quick clamping device is simple in structure, easy to use, accelerated greatly lathe clamping speed, improved the working (machining) efficiency of lathe, and effectively lowered the labour intensity of turner, be applicable to the lathe processing in enormous quantities of same axis products.
Description of drawings
Fig. 1 is the structural representation that the utility model axle is used lathe 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
Axle of the present utility model is with the implementation of lathe quick clamping device for example Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, this quick clamping device mainly by the overcoat 1 that is used for cooperating with lathe chuck 5 clampings, sliding to be plugged in is used for clamping the resilient sleeve 2 of axial workpiece 6 leading sections to be processed and is used for the coaxial tail that is fixed on the tail stock with fixing axial workpiece 6 rearward end to be processed overlapping 4 and forming in the overcoat 1.Wherein, 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; Tail cover 4 is used for front end face towards lathe chuck 5 and axially offers for the blind hole 41 of coincideing and pegging graft and cooperates with axial workpiece to be processed 6 rear ends, the aperture of blind hole 41 locate to be provided with internal diameter by forward direction after diminishing taper hole shape guide frame.
Axle of the present utility model is mainly used in two ends without the Machining of Shaft-type Parts of center positioning hole with the lathe quick clamping device.During use, overcoat 1 is fixedly clamped on lathe chuck 5 by its front end, 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, and the rear end of axial workpiece 6 to be processed is inserted in the tail cover 4 and is held out against by tail stock 7.When tail stock 7 when holding out against axial workpiece 6 to be processed, be subjected to about tail stock 7 axial forces to promote axially to move forward behind the elastic force that resilient sleeve 2 overcomes cylindrical compression spring 3 by axial workpiece 6 to be processed, 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 7, 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 from the jack 20 of resilient sleeve 2, be inserted follow-up axial workpiece to be processed, repeat above-mentioned steps.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.
The utility model is not limited to above-described embodiment, above-mentioned elastic component can also adopt is located at the interior air spring of centre bore cylindrical hole section, dish spring etc., perhaps radially be convexly equipped with the gear edge at resilient sleeve rear end outer peripheral face, cylindrical compression spring is sleeved on outside the resilient sleeve and is mounted between the gear edge of overcoat rear end and resilient sleeve; The centre bore of overcoat also can be stepped hole or the block cooperation when the cylindrical hole inwall is convexly equipped with the realization of gear edge to cylindrical compression spring or the corresponding insertion of axial workpiece to be processed with the jack of resilient sleeve, and it is all within protection domain of the present utility model.
