Abstract
The utility model relates to a brake of a grinding machine, which belongs to grinding machine technology. The utility model is arranged on a motor of the grinding machine and a machine frame of the grinding machine. The utility model comprises a friction brake block which can abutted on a rotor of the motor, a push rod which passes through the machine frame of the grinding machine and the motor of the grinding machine, a button fixed on the upper end of the push rod, a compression spring which is sheathed on the push rod, wherein the push rod is fixed on the friction brake block and the compression spring is positioned between the button and an outer shell of the motor. The friction brake block is fixed on the lower end of the push rod through a connector, and is convenient for replacing after abrasion. The utility model is installed on the grinding machine. When the power of the grinding machine is switched off, the utility model can be quickly braked and stopped. Therefore, the utility model is very safe. The utility model can prevent injury accidents or equipment failures from happening, and can be used for various grinding machines.
Description
Technical field
The utility model belongs to the abrasive machine technical field, more particularly relates to the design of the brake apparatus of abrasive machine.
Background technology
Traditional abrasive machine does not all have brake apparatus.Abrasive machine is after end-of-job, outage, because inertia is bigger, emery wheel generally will rotate the long period, and rotating speed reduces gradually, finally could be static fully.Owing to run out of steam, lose artificial control, in the period, careless slightly at this section that emery wheel stops voluntarily, injury accident or equipment fault will take place.
Therefore, security is relatively poor is a major defect of traditional abrasive machine.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of brake apparatus of abrasive machine is provided.It is installed on the abrasive machine.After abrasive machine is de-energized, can be braked rapidly, be stopped.Thereby fool proof, can avoid the generation of injury accident or equipment fault.
Abrasive machine comprises frame, rack-mounted main shaft and motor, be installed in transmission mechanism between the axle of main shaft and motor, be installed in emery wheel and electric controller on the main shaft.
In order to achieve the above object, the utility model is installed on the motor and frame of abrasive machine, comprises that the shell that can be resisted against the epitrochanterian friction catch piece of motor, the frame of passing abrasive machine and motor is fixed on push rod on the friction catch piece, is fixed on the button of push rod upper end and is sleeved on the push rod and at the shell of button and motor or the compression spring between the stator.
The friction catch piece is fixed on the push rod lower end with connector, the replacing after being convenient to wear and tear.
The utility model is work like this: after abrasive machine is de-energized, down pin button with hand, the tension force that the button that moves down just overcomes the compression spring drives push rod and friction catch piece successively, and the friction catch piece is pushed against on the rotor of motor, forces the rotor of motor to be braked rapidly.After motor stops operating, unclamp the hand of pinning button, under the tension force effect of compression spring, button, push rod and friction catch piece promptly reset backward.
Task of the present utility model comes to this and finishes.
The utility model is installed on the abrasive machine.After abrasive machine is de-energized, can be braked rapidly, be stopped.Thereby fool proof, can avoid the generation of injury accident or equipment fault.Can be widely used in the various abrasive machines.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment 1.A kind of brake apparatus of abrasive machine, as shown in Figure 1.It is installed on the motor and frame 1 of abrasive machine, and the shell 4 that comprises the friction catch piece 3 on the rotor 2 that can be resisted against motor, the frame 1 of passing abrasive machine and motor is fixedly mounted on push rod 5 on the friction catch piece 3, is installed in the button 6 of push rod 5 upper ends and is sleeved on the push rod 5 and the compression spring 8 between the stator 7 of button 6 and motor.
Friction catch piece 3 is fixed on the lower end of push rod 5, the replacing after being convenient to wear and tear by connector 10.Friction catch piece 3 has back connecting axle 11, and connector 10 is connected push rod 5 to press closer screw with back connecting axle 11.Unclamp and press closer screw, just replaceable friction catch piece 3.
Embodiment 1 is installed on the abrasive machine.After abrasive machine is de-energized, can be braked rapidly, be stopped.Thereby fool proof, can avoid the generation of injury accident or equipment fault.Can be widely used in the various abrasive machines.
Claims (2)
