Between contrate gear on described brake axle and brake axle, adopt that slide key is movable to be coordinated.
The beneficial effect that the utility model produces is:
Ball-screw in NC Machine Tools non-displacement device of the present utility model, can effectively brake ball screw, is specially adapted to vertical lift system or at a high speed large inertia system; Simultaneity factor provides certain buffering surplus, safe and reliable while guaranteeing to brake, rapidly and efficiently.The utility model is simple in structure, with low cost, operates simple and easy, easy to usely, is easy to use on a large scale and promote.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure represents: 1-bed piece, 2-spring, 3-contrate gear, 4-contrate gear, 5-torsion spring, 6-ball nut, 7-ball-screw, 8-machine tool motion component, 9-electromagnet, 10-holder, 11-packing ring, 12-nut, 13-brake axle.
The specific embodiment
Shown in Fig. 1, the utility model is a kind of Ball-screw in NC Machine Tools non-displacement device, comprises brake axle 13, electromagnet 9, spring 13 and a pair of intermeshing contrate gear 3 and 4.
Brake axle 13 is arranged on vertically one end of ball screw 7 and contacts with the end of ball screw 7, and the other end of this brake axle 13 is fixedly connected on bed piece 1.In this specific embodiment, use the 10 pairs of brake axles 13 of holder that are fixedly mounted on bed piece 1 to be connected and fixed, on holder 10, be provided with the installing hole of brake axle 13.13 pairs of brake axles should installing hole end be provided with external screw thread, therefore, brake axle 13 is inserted after the installing hole of holders 10, use nut 12, this fixed axis 13 installed and is connected on holder 10.Meanwhile, for strengthening the connection of brake axle 13 and holder 10, be also provided with the keyway and the key that cooperatively interact between the two, further guarantee being connected and fixed of parts.
On brake axle 13, be set with successively electromagnet 9, spring 2 and contrate gear 3.Wherein: the installation site of electromagnet 9 is fixed, in this specific embodiment, electromagnet 9 adopts key to connect between brake axle 13, and meanwhile, a side of electromagnet 9 is fixedly connected on bed piece 1.Spring 2 is sleeved on brake axle 13, can stretches within the specific limits and compress, and the two ends of spring 2 connect electromagnet 9 and contrate gear 3.Contrate gear 4 is fixedly mounted on ball screw 7 ends that contact with brake axle 13, and the profile of tooth on contrate gear 3 and 4 end faces is oppositely arranged, and the profile of tooth when both contact, on contrate gear 3 and 4 end faces is intermeshing.
In this device specific embodiment, contrate gear 4 inner sides on ball screw 7 are set with a torsion spring 5, the bar portion stage casing of these torsion spring 5 two ends difference connecting end surface fluted disc 4 inner faces and ball screw 7.The effect of torsion spring 5 is, at contrate gear 3 during to contrate gear 4 motion, for contrate gear 4 provides certain moment of torsion, make profile of tooth on contrate gear 4 end faces can with contrate gear 3 fast corresponding, mesh, can not damage the profile of tooth of contrate gear 3 and 4.Meanwhile, after contrate gear 3 and 4 engagements, torsion spring 5 also provides certain buffering for the braking of ball screw 7, can not cause the stuck situation of system.
Contrate gear 3 is metal fluted discs that the magnetic attraction that can be produced by electromagnet 9 attracts.Therefore, after electromagnet 9 energising, contrate gear 3 is by the electromagnetic attracting force of electromagnet 9, move to electromagnet 9 along brake axle 13 directions, thereby makes contrate gear 3 separated with 4, and now, spring 2 is in compressive state.
This installs maximum feature is to use the mode of braking of end face tooth structure, has increased greatly braking reliability; In addition, in leading screw contrate gear 3 inside, torsion spring 5 is housed, can increases certain cushioning effect, and then reduce the impact that mechanism receives, play the effect of protection.
Using method of the present utility model is as follows:
Machine tool motion component 8 is connected on ball screw 7 by ball nut 6, while normally working under the driving of ball-screw 7 at motor, the electric power assembly of lathe is to electromagnet 9 energisings, make it produce magnetic attraction, pull contrate gear 3 separated with contrate gear 4, thereby ball screw 7 can normally be worked, now, spring 2 pressurized compressions.
When needs are braked ball screw 7, disconnect the power supply of electromagnet 9, the magnetic field that electromagnet 9 is produced disappears, and the spring 2 of compression before resets, and the elastic potential energy of gathering on spring 2 makes contrate gear 3 rapidly to contrate gear 4 direction motions.At contrate gear 3 contact contrate gears 4 in a flash, torsion spring 5 make contrate gear 4 slightly rotate, make the profile of tooth of contrate gear 4 and profile of tooth on contrate gear 3 mutually corresponding, mesh, thereby reach the effect of fast braking ball screw 7.
The braking fluted disc 3 moving with ball-screw is departed from, spring 1 pressurized, ball-screw is normally worked.During power-off, electromagnet 4 magnetic fields disappear, and spring 1 reset pushing active toothed disk 2 moves down braking fluted disc 3 engagements with ball-screw, and ball-screw is braked.
