Description
Technical field
The utility model relates to machine tool field, specifically, relates to a kind of lathe Z axle braking device.Be mainly used in locking to JM500 lathe Z axle.
Background technology
Existing JM500 lathe is under cold situation, and the Z axle is a ball-screw, because gliding can appear in the heavier reason of its deadweight, causes processing difficulties, even can cause the accident, and causes unnecessary loss.Avoiding the Z axle to glide is the problem that people press for solution.
Summary of the invention
The purpose of this utility model provides a kind of lathe Z axle braking device that can prevent under the cold situation of lathe that the Z axle from gliding.
The technical scheme that realizes above-mentioned purpose is: a kind of lathe Z axle braking device, by the brake connecting axle, the locking external gear, the locking internal gear, electromagnet, the electromagnet installing plate, the internal gear pressing plate, fixed head, spring support becomes with compression spring set, the locking external gear is fixedly mounted on the brake connecting axle, and with locking internal gear engagement, the locking internal gear is rotatably installed on the fixed head, and between internal gear pressing plate and fixed head, electromagnet is fixed on the electromagnet installing plate, and between internal gear pressing plate and electromagnet installing plate, spring support is fixed on the electromagnet installing plate, the compression spring is installed on the spring support, and the upper end of compression spring is against on the spring support, the lower end is against on the internal gear pressing plate, and the electromagnet installing plate links together by bolt and fixed head, and this bolt passes the internal gear pressing plate.
After adopting technique scheme, when electromagnet is switched on, the active force that the magnetic force of electromagnet overcomes the compression spring upwards picks up the internal gear pressing plate, the internal gear pressing plate internal gear that goes out of lock, thereby the locking internal gear can be rotated, the locking external gear also just can rotate like this, thereby the brake connecting axle does not lock, and makes Z axle operate as normal.When the electromagnet no power, electromagnet suction disappears, the active force of compression spring acts on the internal gear pressing plate, the internal gear pressing plate is pressed on the locking internal gear on the fixed head, and the locking internal gear cannot be rotated, and locks external gear like this and also cannot rotate, thereby make the locking of brake connecting axle, reaching the fixed purpose of Z shaft lock, thereby prevent that the Z axle from gliding, and ensures safety in production.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Shown in Fig. 1～8, a kind of lathe Z axle braking device, by brake connecting axle 1, locking external gear 2, locking internal gear 4, electromagnet 8, electromagnet installing plate 7, internal gear pressing plate 5, fixed head 3, spring support 9 and compression spring 6 are formed, locking external gear 2 is fixedly mounted on the brake connecting axle 1, and with the engagement of locking internal gear 4, locking internal gear 4 is rotatably installed on the fixed head 3, and between internal gear pressing plate 5 and fixed head 3, electromagnet 8 is fixed on the electromagnet installing plate 7, and between internal gear pressing plate 5 and electromagnet installing plate 7, spring support 9 is fixed on the electromagnet installing plate 7, compression spring 6 is installed on the spring support 9, and the upper end of compression spring 6 is against on the spring support 9, the lower end is against on the internal gear pressing plate 5, electromagnet installing plate 7 links together by bolt 10 and fixed head 3, and this bolt 10 passes internal gear pressing plate 5.
As shown in Figure 1, spring support 9 is a screw rod, and screw rod is threaded with electromagnet installing plate 7, and fixes with two nuts, and compression spring 6 is sleeved on the screw rod.It is very convenient to adopt this structure to install.
Operation principle of the present utility model is as follows: when electromagnet 8 energisings, the magnetic force of electromagnet 8 upwards picks up internal gear pressing plate 5 greater than the pressure of compression spring 6, internal gear pressing plate 5 internal gear 4 that goes out of lock, thereby locking internal gear 4 can be rotated, the locking external gear can rotate like this, thereby brake connecting axle 1 does not lock, and makes Z axle operate as normal.When electromagnet 8 no powers, electromagnet 8 suction disappear, the active force of compression spring 6 acts on the internal gear pressing plate 5, internal gear pressing plate 5 is pressed on locking internal gear 4 on the fixed head 3, locking internal gear 4 cannot be rotated, locking external gear 2 also cannot rotate like this, thereby makes 1 locking of brake connecting axle, to reach the fixed purpose of Z shaft lock.
