Description

Brake device

The present invention relates to a brake device, and more particularly to a brake device that can be applied to a linear motion brake.

The brake device is used to decelerate the movable member and tend to be stationary. Most of the brake device is divided into two parts and is respectively disposed on a movable member and a relatively stationary member. For example, the disc brake of the locomotive is to separate the disc and the disc. It is disposed on the rotating wheel and the relatively stationary front fork. When the user presses the brake handle, it will drive the sheet to press against the disc, thereby stopping the disc from continuing to perform circular motion to achieve the braking effect.

Referring to FIG. 1 , an electromagnetic brake device 1 is also provided on a machine tool or other implement, which includes a fastener piece 12 fixed to a drive shaft 11 , a fixed to the drive shaft 11 and located on the drive piece 12 . a first fixing seat 13 on one side, a second fixing seat 14 fixed on the first fixing seat 13 and on the opposite side of the guiding piece 12, and a slidably sleeved on the guiding piece a friction plate 15 on the 12 and between the second fixing seat 14 and a coil fixed on the second fixing base 14 and located between the second fixing seat 14 and the friction plate 15 16, and a plurality of springs 17 connected to the second fixing seat 14 and the movable friction plate 15 respectively. The movable friction plate 15 is made of a magnetic material. Therefore, when the coil 16 is energized to generate a magnetic force, the movable friction plate 15 can be adsorbed on the coil 16 as shown in FIG. 1, and the movable friction plate 15 can be This allows the sheets 12 to be spaced apart without contact, at which point the drive shaft 11 is free to rotate. The movable friction plate 15 compresses the springs 17 during the abutting against the coil 16 and the second fixing base 14. When the coil 16 is not energized and does not generate a magnetic force, the springs 17 push the elastic force through the elastic force. The movable friction plate 15 moves the movable friction plate 15 away from the coil 16 and presses against the blade 12, and the movable friction plate 15 and the blade 12 fixed to the transmission shaft 11 rub against each other to make the transmission shaft 11 can not be rotated, which in turn produces a braking effect.

However, since the electromagnetic brake device 1 can only generate a braking effect on the circular motion, it must be disposed on a rotating member such as a wheel body or a transmission shaft 11. For an implement that moves in a linear direction, it is necessary to additionally add a linear motion to The components of the circular motion are low in generality and will increase the difficulty of configuration.

Therefore, the object of the present invention is to provide a brake device that can directly correspond to linear motion.

Therefore, the brake device of the present invention is disposed on a setting body, the setting body is spaced apart from a magnetic counterpart in a first direction, and the setting body is vertically perpendicular to the corresponding body. The second direction moves. The brake device is located between the corresponding body and the installation body along the first direction, and includes a fixing unit fixed to the setting body, a braking unit disposed on the fixing unit, an electromagnetic control unit, and a a reset unit disposed between the fixed unit and the brake unit.

The brake unit is movable relative to the fixed unit in a first direction between a non-brake position and a brake position. When the brake unit is located at the non-brake position, the brake unit is spaced from the corresponding body to make the set body The movable body is movable in the second direction relative to the corresponding body. When the braking unit is located at the braking position, the braking unit is pressed against the corresponding body to brake the setting body relative to the corresponding body. The electromagnetic control unit is controllable to generate a magnetic force to adsorb the corresponding body, thereby causing the brake unit to move from the non-brake position to the brake position. The reset unit can drive the brake unit to be reset from the brake position to the non-brake position by the elastic restoring force when the electromagnetic control unit does not generate a magnetic force.

The function of the present invention is that the brake unit can be driven by the electromagnetic control unit to move from the non-brake position to the brake position, thereby causing the brake unit to directly press against the corresponding body to generate a braking effect. The present invention can be directly disposed on a linearly moving body relative to the corresponding body, for example, on a machine moving along a track, and does not need to transmit a linear motion into a circular motion through a transmission shaft or other mechanism, and the installation is simple and High versatility and reduced structural complexity.

When the coil 231 is not energized and no magnetic force is generated, the magnet 232 is attracted by the corresponding body 32 to be attracted to the corresponding body 32, thereby driving the brake unit 22 to move from the non-brake position to the brake position. When the coil 231 is energized, a magnetic force is generated to cancel the magnet 232, so that the magnet 232 is no longer attracted to the corresponding body 32, and the brake unit 22 is driven by the tower spring 241 to be reset by the brake position. This non-brake position. Unlike the first embodiment, which performs braking when energized, the second embodiment provides a variation of braking when power is off, which can be applied to different working environments or needs.
