Abstract
The utility model discloses a braking device of a rotary shaft of a numerical control machine tool. The braking device comprises the rotary shaft (1) and a rotary shaft box body (2), wherein the rotary shaft (1) passes through the rotary shaft box body (2); an electromagnetic brake armature (3) is sleeved at the rear end of the rotary shaft (1); and an electromagnetic brake coil (4) is arranged between the electromagnetic brake armature (3) and the rotary shaft box body (2). The braking device has the advantages that by utilizing the principle that the electrically conducting coil can produce a magnetic field when being electrified and the electromagnetic brake armature can be tightly pressed on the electrified electrically conducting coil, a static friction force is obtained, the rotary shaft is tightly held and the aim of braking the rotary shaft is achieved, so that the braking reaction time is short; and besides, the structure of the braking device is simple and the whole structure of the numerical control machine tool can be simplified.
Description
Technical field
The utility model relates to a kind of brake apparatus, especially a kind of brake apparatus of Digit Control Machine Tool gyroaxis.
Background technology
At present, the gyroaxis of Digit Control Machine Tool normally adopts its braking of hydraulic pressure or pneumatic means control; But, be hydraulic pressure or pneumatic means its take up room all greatlyyer, and brake reaction time is slower; Mechanism is complicated, needs to increase a cover hydraulic pressure or an apparatus for pressurizing gas, liquid, and manufacturing cost is high.
Summary of the invention
The purpose of the utility model is: a kind of brake apparatus of Digit Control Machine Tool gyroaxis is provided, and it is simple in structure, and brake reaction time is fast, and good braking effect is to overcome the deficiency of prior art.
The utility model is achieved in that the brake apparatus of Digit Control Machine Tool gyroaxis; Comprise gyroaxis, gyroaxis casing; Gyroaxis passes the gyroaxis casing, is with electromagnetic brake armature at the revolution the tip of the axis, between electromagnetic brake armature and gyroaxis casing, is provided with the electromagnetic brake coil.
Since adopted technique scheme, compared with prior art, the principle in generation meeting magnetic field when the utility model utilizes the conductive coil energising; Can be pressed on through electromagnetic brake armature on the conductive coil of energising, thereby obtain a stiction, and hold gyroaxis tightly; Play the purpose of brake rotary axle; So not only brake reaction time is fast, and brake apparatus is simple in structure, can simplify the overall structure of Digit Control Machine Tool.The utility model is made easily, and is with low cost, and result of use is good.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
The specific embodiment
The embodiment of the utility model: the structure of the brake apparatus of Digit Control Machine Tool gyroaxis is as shown in Figure 1; Comprise gyroaxis 1, gyroaxis casing 2; Gyroaxis 1 passes gyroaxis casing 2; End at gyroaxis 1 is with electromagnetic brake armature 3, between electromagnetic brake armature 3 and gyroaxis casing 2, is provided with electromagnetic brake coil 4.
In use, when needs make the gyroaxis braking, just press locking key; Make 4 energisings of electromagnetic brake coil; Can produce magnetic field after 4 energisings of electromagnetic brake coil, electromagnetic brake armature 3 is received the influence in this magnetic field, will compress electromagnetic brake coil 4; The stiction that electromagnetic brake armature 3 produces when compressing electromagnetic brake coil 4 can be held gyroaxis 1 tightly, has so just realized the braking of gyroaxis 1.
