Abstract
The utility model discloses an aluminum sawing machine brake device comprising a brake disc (4) fixedly disposed on an output shaft of a motor (5) and an electromagnet (2) fixedly disposed on an aluminum sawing machine head housing (1). An end surface of the electromagnet (2) is provided with a friction lining (3) cooperated with the brake disc (4). The electromagnet (2) comprises an outer iron core (21), an electromagnetic coil (22), a reset spring (23), and a T-shaped iron core (24). The electromagnetic coil (22) is disposed on the outer iron core (21), and the reset spring (23) and the T-shaped iron core (24) are sequentially disposed in a central hole in the outer iron core (21). The friction lining (3) is fixedly connected with the end surface of the T-shaped iron core (24). By adopting the above mentioned structure, the aluminum sawing machine brake device has advantages of simple and reasonable structure, convenient operation and use, good brake effect, stability, reliability, and long service lifetime.
Description
Technical field
The utility model relates to a kind of saw aluminium machine, particularly a kind of brake gear of sawing aluminium machine saw blade fast braking.
Background technology
Saw aluminium machine is a kind of electric tool commonly used of sawing aluminium alloy extrusions, is widely used in building, decoration, furniture industry, and it has not only alleviated operator's labour intensity, and has high efficiency, the advantage such as easy to use.In order to reach the purpose of safe handling, the safety of saw aluminium machine requires machine to stop operating by saw blade in the stipulated time after switch disconnects, in order to realize the requirement of safety, existing saw aluminium machine generally adopts motor and switch to combine, in the stator winding of motor, increase a brake winding, and in conjunction with the electric current of in a flash giving a motor backwards rotation of switch in the switch disconnection, reach the purpose of brake.Adopt said structure to have following problem: the one, need around two windings in the stator, increased the difficulty that motor is made; The 2nd, motor carbon brush in the process of brake can produce very large spark, has increased the wearing and tearing of carbon brush and commutator, has shortened useful life.For this reason, many manufacturers and knowledgeable people have carried out R and D, but do not have so far desirable product to emerge.
Summary of the invention
For overcoming existing saw aluminium machine above shortcomings in brake process, the purpose of this utility model provide a kind of simple and reasonable, easy for operation, braking effect is good, the steady saw aluminium machine brake gear of reliable, long service life.
The utility model solves the problems of the technologies described above the technical scheme that adopts, and it comprises the brake disc that is fixed on the motor output shaft, is fixed on the electromagnet on the saw aluminium head shell, and the end face of electromagnet is fixed with the friction plate that matches with brake disc.
Described electromagnet comprises outer iron core, solenoid, back-moving spring and T-shaped iron core, and solenoid is arranged on the outer iron core, and back-moving spring and T-shaped iron core are installed in the centre bore of outer iron core successively, and friction plate is fixedly connected with the end face of T-shaped iron core.
After adopting said structure; compared with prior art have the following advantages and effect; owing at motor output shaft brake disc being set; at saw aluminium head shell electromagnet is set; the end face of electromagnet is fixed with friction plate; by reaching friction plate and cooperating of brake disc the purpose of shutting down brake; the brake structure advantages of simple; can not increase the difficulty that motor is made; install easy to process; brake is steadily reliable, has solved brake winding carbon brush in the process of brake and has produced very large spark; carbon brush and commutator wear are serious; the problem that useful life is short increases useful life of complete machine greatly.

Fig. 2 is the utility model decomposition texture schematic diagram.
Wherein 1 saw aluminium head shell, 2 electromagnet, 3 friction plates, 4 brake discs, 5 motors, 6 saw blades, 7 travelling gears, 21 outer iron cores, 22 solenoids, 23 back-moving springs, 24T shaped iron core.
Embodiment
Illustrated in figures 1 and 2, specific embodiments for the utility model saw aluminium machine brake gear, it comprises the brake disc 4 that is fixed on motor 5 output shafts, is fixed on the electromagnet 2 on the saw aluminium head shell 1, and the end face of electromagnet 2 is fixed with the friction plate 3 that matches with brake disc 4.Described electromagnet 2 comprises outer iron core 21, solenoid 22, back-moving spring 23 and T-shaped iron core 24, solenoid 22 is arranged on the outer iron core 21, back-moving spring 23 and T-shaped iron core 24 are installed in the centre bore of outer iron core 21 successively, and friction plate 3 is fixedly connected with the end face of T-shaped iron core 24.
During the utility model plugged switch, motor 5 is switched on simultaneously with electromagnet 2, solenoid 22 makes outer iron core 21 produce magnetic field T-shaped iron core 24 is produced suction, T-shaped iron core 24 band movable friction plates 3 move and compression reseting spring 23, friction plate 3 is separated with brake disc 4, motor 5 output shafts drive brake disc and rotate, and drive saw blade 6 rotary works by travelling gear 7 simultaneously.When shutting down disconnecting power switch; motor 5 rotors are rotated further under the effect of inertia; simultaneously electromagnet 2 outages; solenoid 22 makes outer iron core 21 produce the magnetic field disappearance; this moment, T-shaped iron core 24 outwards ejected under back-moving spring 23 promotes, and the friction plate 3 that is fixed on the T-shaped iron core 24 is contacted with brake disc 4 produce frictional force, produced braking action; motor 5 is stopped operating in setting time, thereby reach the requirement of safety defined.
Claims (2)
1. saw aluminium machine brake gear for one kind, it is characterized in that: it comprises the brake disc (4) that is fixed on motor (5) output shaft, is fixed on the electromagnet (2) on the saw aluminium head shell (1), and the end face of electromagnet (2) is fixed with the friction plate (3) that matches with brake disc (4).
2. saw aluminium machine brake gear according to claim 1, it is characterized in that: described electromagnet (2) comprises outer iron core (21), solenoid (22), back-moving spring (23) and T-shaped iron core (24), solenoid (22) is arranged on the outer iron core (21), back-moving spring (23) and T-shaped iron core (24) are installed in the centre bore of outer iron core (21) successively, and friction plate (3) is fixedly connected with the end face of T-shaped iron core (24).
