Description
Technical field
The utility model relates to a kind of non-standard clamping device, relates to a kind of lathe inner clamping type elastic jacket specifically.
Background technology
All there is not the engine lathe with automated exchanged cutter in present many factories, numerically controlled lathe, and clamping workpiece adopts the chuck clamping, the labour intensity height, efficient is low; Since workpiece rotation during turning, essential parking clamping during workpiece loading and unloading, for production in enormous quantities, single process operation, the clamping that frequently stops, lathe energy consumption of electrical machinery height, temperature rise, the brake heating is big, brake and electrical fault height; The inner clamping type elastic jacket all has application as a kind of quick, convenient installation way on a lot of equipment; Elastic jacket groundwork principle is to make elastic jacket flick clamping work pieces by load transfer devices such as screw rods.The most frequently used tensioner mode generally has dual mode: a kind of is that workpiece is motionless, and the frock simplicity of design mainly is used on the lathe of cutter rotation; A kind of is workpiece rotation, mainly is used on the equipment of workpiece rotation such as lathe.With the elastic expansion-sleeve tensioner of not stopping, improved procedure mainly contains following two kinds for lathe: 1, on small-sized lathes such as instrument lathe, its mode of transfer force is for to be provided with a lever at the main shaft end, and pushing drawing rod is realized tensioner; Generally by installing servicing units such as hydraulic cylinder additional, drive pull bar tensioner ringfeder for engine lathe and numerically controlled lathe at the main spindle box end; Because instrument lathe does not have gear, rotating speed is higher, and throw of lever is big, and lever is installed in the main spindle box end, and workman's work range is big, is mainly used in the miniature workpiece processing; The hydraulic cylinder tensioner need be equipped with hydraulic system, invest bigger, complex structure.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, and provides a kind of simple in structure, the efficient height, and the workman is easy to operate, can realize not stopping operation, invests less lathe inner clamping type elastic jacket.
Technical solution of the present utility model is: lathe with the inner clamping type elastic jacket is: on Lathe Spindle Box fore bearing end cap by the nut bearing that is threaded, on the nut bearing by the power transmission nut that is threaded, on the power transmission nut, one handle is installed, on lathe spindle, pass through bolt, the seam expander axle symmetry on the expander axle that is located by connecting is installed the bearing pad, on the bearing pad, clutch bearing is installed, in expander axle endoporus, mandrel is housed, one end of spring is packed in the mandrel endoporus, one end withstands on and holds out against on the nut, the other end at expander axle endoporus is installed ringfeder, and pull bar penetrates with mandrel from this end and is connected.
Clutch bearing described in the technical solution of the present utility model is the automobile clutch bearing, and clutch bearing is connected with the contact of power transmission nut.
The utility model beneficial effect:
1. because nut bearing 7 is installed on Lathe Spindle Box 1 fore bearing end cap 2, the mounting structure compactness from operator's distance closely, needs only during operation and can realize clamping workpiece at 90 ° of scope rotary handles 10.
2. nut adopts the closely-pitched transmission, and reinforcement is big, and self-locking performance is good, firm workpiece clamping, and workman's operation saves time, laborsaving.
3. the power transmission bearing adopts the automobile clutch bearing, rather than plane bearing commonly used, axially the power transmission bearing be regardless of from, simple in structure, can not cause the clamping workpiece inefficacy because of the lathe rotation drives 11 rotations of power transmission nut.
4. the clamping that do not stop, the power consumption of lathe motor is little, and electric machine temperature rise is low; By to ordinary lathe, when the turning pre-stress anchor clipper, flat both ends of the surface chuck clamping efficient than before improve 2 times, all need keep in repair in every month before the motor, and brake need be changed February, after the improvement, does not need brake, and motor need not keep in repair substantially.
5. structural design is simple, and whole improvement expenses is very low, and most of midget plants can transform, and according to workpiece endoporus difference, changes supporting pull bar 15 and ringfeder 13 and gets final product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
The specific embodiment
As Fig. 1, shown in 2, on Lathe Spindle Box 1 fore bearing end cap 2 by the nut bearing 7 that is threaded, on the nut bearing 7 by the power transmission nut 11 that is threaded, one handle 10 is installed on power transmission nut 11, on lathe spindle 3, pass through bolt, the seam expander axle 4 that is located by connecting, symmetry is milled two grooves on expander axle 4, bearing pad 8 symmetries are installed on the groove of expander axle 4, automobile clutch bearing 9 is installed on bearing pad 8, clutch bearing 9 is connected with 11 contacts of power transmission nut, on expander axle 4, be provided with endoporus, in the endoporus of expander axle 4 by an end of lathe spindle 3 mandrel 12 is housed, in mandrel 12 endoporus spring 6 is housed, be fixed with on this termination of expander axle 4 and hold out against nut 5, the end that spring 6 stretches out mandrel 12 withstands on and holds out against on the nut 5, and ringfeder 13 is installed on the other end of expander axle 4 endoporus, and pull bar 15 penetrates with mandrel 12 from expander axle 4 endoporus of this end and is connected.
Operation principle of the present utility model is: workpiece 14 penetrates in the ringfeder 13, locate by expander axle 4 end faces, turn handle 10 drives power transmission nut 11 and axially moves, power transmission nut 11 in Lathe Spindle Box 1 one lateral movement processes, promote clutch bearing 9, bearing pad 8, mandrel 12 and the pull bar 15 that connects with mandrel 12 to Lathe Spindle Box 1 one lateral movements, pull bar 15 end frustums enter in the ringfeder 13 awl cups, the outside spreading of ringfeder 13 tensioner sheets, stretching workpiece 14, return spring 6 compressions simultaneously, parameter starts lathe in accordance with regulations, can realize workpiece 14 processing.After processing, oppositely turn handle 10 drive power transmission nuts 11 axially move, power transmission nut 11 is in Lathe Spindle Box 1 a reverse lateral movement process, and the pressure of power transmission nut 11 is no longer born in clutch bearing 9 ends, under the effect of return spring 6, promotion mandrel 12, bearing pad 8, clutch bearing 9, pull bar 15 reset, pull bar 15 frustums withdraw from ringfeder 13 awl cups simultaneously, and ringfeder 13 tensioner sheets reset, and can take off workpiece 14, dispense with parking is simultaneously by the above step workpiece 14 of packing into.
