Description

Tower type electric turning cutter holder

The utility model belongs to the auxiliary products of numerically controlled lathe, relates in particular to a kind of tower motoring knife rest.

The motoring knife rest of domestic production at present, motor all exposes to the knife rest rear end, and knife rest drives and adopts worm gear pairs, and spiral lifting is adopted in lifting, and rubber seal is adopted in sealing.Its shortcoming is that profile is not attractive in appearance, and electric wire exposes motor easy damaged, easily water inlet; The 2nd, owing to adopt worm gear pairs to drive, transmission is imitated low; The 3rd, tool-changing speed is slow; The 4th, rubber seal is easy to wear, and sealing is not leaned on can.

The purpose of this utility model provides a kind of good looking appearance, transmission efficiency height, the tower motoring knife rest that tool-changing speed is fast.

The utility model is to realize like this, between upper knife body ［ 6 ］ and lower knife body ［ 11 ］, be provided with a fixed center axis ［ 10 ］, motor ［ 1 ］ is located on the fixed center axis ［ 10 ］ of upper end of upper knife body ［ 6 ］, its output is with the train planetary reducer ［ 2 that is located on the central shaft ［ 10 ］, 3 ］ input gear connects, train planetary reduction gear dress ［ 2,3 ］ overhead cam that the same cam that is located on the fixed center axis ［ 10 ］ of output shaft is paid ［ 4 ］ links, the following cam that cam is paid ［ 4 ］ connects firmly mutually with upper knife body ［ 6 ］, pay at lower knife body ［ 11 ］ and cam between the following cam of ［ 4 ］ and be provided with elastic device ［ 12 ］, cam pay be provided with between the following cam coaxial ［ 10 ］ of ［ 4 ］ anti-by pin ［ 13 ］.

Because the electronic upper end that is located at cutter hub of the present utility model, knife rest drives and adopts train planetary reduction gear dress, and cam gear is adopted in the knife rest lifting, thus the utlity model has aesthetic in appearance, the transmission efficiency height, tool-changing speed is fast, seals reliable advantage.

Accompanying drawing is a structural representation of the present utility model.

1-motor among the figure; The 2-internal gear is paid; The 3-planetary gear is paid; The 4-cam is paid; The 5-dewatering orifice; The 6-upper knife body; The 7-screw rod; The 8-pressure knife block; The 9-signal transmitter; The 11-lower knife body; The 12-spring; 13-is instead by pin.

Now in conjunction with the accompanying drawings embodiment of the present utility model is described further:

Between upper knife body ［ 6 ］ and lower knife body ［ 11 ］, be provided with a fixed center axis ［ 10 ］, motor ［ 1 ］ just is contained in the last top of fixed center axis ［ 10 ］, the output shaft of motor ［ 1 ］ is paid ［ 2 ］ with internal gear and is linked, the internal gear that internal gear is paid ［ 2 ］ is contained on the fixed center axis ［ 10 ］ by bearing, being located at fewer differential teeth planetary tooth on the fixed center axis ［ 10 ］ pays ［ 3 ］ and pays ［ 2 ］ with internal gear and link, small teeth number difference planet gear is paid the overhead cam that the tie-rod of ［ 3 ］ pays ［ 4 ］ with cam and is linked, overhead cam is contained on the fixed center axis ［ 10 ］, and can rotate around axle ［ 10 ］, be shaped as garden shape, be provided with criss-cross slide block in the top, following cam face is with the overhead cam unanimity, the same upper knife body of following cam ［ 6 ］ fixedly is associated in together, be provided with 3 holes between the last lower knife body, spring ［ 12 ］ is housed in the hole, ball is housed in the spring upper end.

Be provided with between cam and the fixed center axis down instead by lock ［ 13 ］, anti-is a ratchet mechanism by lock, can only rotate to a direction.Between the end-toothed disc of lower knife body ［ 11 ］ and waterproof ring, be provided with discharge sump, be provided with in the lower end of groove and groove hole ［ 5 ］ mutually.Between the upper end of motor ［ 1 ］ is with upper knife body, be provided with the taper case, play protection motor and good looking appearance effect.

The course of work of the present utility model is such, after motor ［ 1 ］ is received the tool changing signal that signal transmitter ［ 9 ］ sends, drive internal gear and pay ［ 2 ］ rotation, internal gear is paid ［ 2 ］ and is driven small teeth number difference planet gear again and pay ［ 3 ］ and rotate, small teeth number difference planet gear is paid ［ 3 ］ and is driven cam by the cross slide block on the overhead cam that is located at cam and pays ［ 4 ］ and pay the epirelief crop rotation microinching of ［ 4 ］, after the projection of overhead cam slides into down in the groove of cam, under the effect of spring ［ 12 ］, make upper knife body ［ 6 ］ and lower knife body ［ 11 ］ end-toothed disc separately, and select cutter, when upper knife body ［ 6 ］ when going to required cutter spacing, signal transmitter ［ 9 ］ sends signal, make motor ［ 1 ］ counter-rotating, owing to be provided with between cam and the fixed center axis down instead by lock ［ 13 ］, so upper knife body ［ 6 ］ is reverse turn again, the projection of overhead cam then skids off from the groove of following cam, and makes it is that end-toothed disc clamps between upper knife body ［ 6 ］ and the lower knife body ［ 11 ］.
