Description

Linear slide clamp

The present invention relates to a linear slide clamp, and more particularly to a brake device that is applied to a linear slide to provide quick operation and high stability in an emergency power failure.

According to the linear slide mechanism, the workbench is mainly attached to the slide seat, and the inner rolling of the steel ball on the slide rail is applied to achieve the low-resistance, low-vibration and low-noise motion effect of the worktable. Therefore, linear slides have been widely used in applications such as machine tools, industrial machinery, work stations, conveyor equipment, etc., in any mechanism that requires linear motion. Press again, the sliding seat is not only a component that provides low resistance, but also does not install any braking mechanism that conflicts with low resistance. Therefore, in the case of emergency power failure, the workbench cannot be fixed immediately due to the inertia of motion. It will cause damage to the workpiece and damage. Especially with the development of high-speed machining technology, in the case of emergency power failure, the sliding seat can not be immediately caught, which not only causes damage to the workpiece and the tool or equipment, but even endangers the operators on site.

In recent years, there have been many creations in this technical field, which are countermeasures against the emergency braking of linear slides, such as Bulletin No. 514166 [Rolling device for linear slides]; the method is based on the side of the slide rail. a brake lever, the middle portion of the brake lever is provided with a groove with a tapered surface, and the rear end is pushed by a disc spring; during the running phase of the carriage, the piston rod on the side of the brake rod is pushed by the air pressure In the recessed groove of the brake lever, the brake lever is retracted from the contact slide rail; when the emergency power is cut off, the air pressure source stops working, and the brake lever can frictionally contact the slide rail through the pushing of the disc spring, and directly apply the brake force to the brake rail. On the rails, the effect of emergency braking is achieved.

The utility model [the linear slide rail brake device] can provide the effect of the linear slide rail power failure emergency braking; however, the device is configured such that the piston rod is laterally inserted into the bracket of the brake rod to retreat the brake rod, and the brake rod is retracted. Since the rear end is provided with a disc spring, the device must be designed such that the left and right sets of piston ejector pins are simultaneously inserted into the recessed groove, so that there is sufficient force to cause the brake lever to retreat against the thrust of the disc spring, that is, the device needs A plurality of sets of piston rods with supercharging function provide greater power to retract the brake rod; therefore, the mechanism of the device is complicated, and the manufacturing cost and running cost are also high. In fact, the device is less economical.
