Abstract
The utility model discloses a rapid spindle brake device for a numerically-controlled machine tool. The device comprises a spindle box, wherein a spindle is arranged in the spindle box; a magnetic brake disc is fixedly arranged on the spindle; a brake bracket is arranged on the spindle box; a brake control cylinder is arranged on the brake bracket; an output end of the brake control cylinder is in control connection with a pair of brake clamping blocks positioned on two sides of the magnetic brake disc; an elastic recovery device is connected between the pair of brake clamping blocks; a magnetic adsorption device is arranged on the brake clamping blocks. When a motor of the numerically-controlled machine tool stops rotating, the brake control cylinder controls the brake clamping blocks to clamp, and friction force between the brake clamping blocks and the magnetic brake disc is increased due to the magnetic adsorption force of the magnetic adsorption device, so that the spindle rapidly stops rotating. When the motor stops working, the spindle rapidly stops rotating, the time is saved, the working efficiency is improved, and the rapid spindle brake device is simple in structure and good in brake effect.
Description
technical field
The utility model relates to a kind of machining equipment, relates in particular to a kind of main shaft of numerical control machine tool fast braking device.
Background technology
Lathe is generally divided into Metal Cutting Machine Tool, forging machine tool and wood craft machines etc.In modern mechanical manufacturing, to adding the higher machine components of required precision, generally all need on lathe, by the method for cutting, finally process, so lathe plays significant role in the construction of national economic modernization.Main shaft device is used for driving workpiece or cutter rotation as an important component part of lathe, and the kinematic accuracy of main shaft device and the rigidity of structure directly affect crudy and stock-removing efficiency.There is following shortcoming in the main shaft device of traditional machine tool: when the motor that drives main shaft to rotate quits work, main shaft is because inertia can continue rotation, if carrying out next step manufacturing procedure must wait for after main shaft stops the rotation and just can carry out, in the process of main shaft stall, waste a lot of time, reduced operating efficiency.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of main shaft that makes fast when motor quits work and stops the rotation, and saves time, and increases work efficiency, simple in structure, the main shaft of numerical control machine tool fast braking device that braking effect is good.
For solving the problems of the technologies described above, the technical solution of the utility model is: main shaft of numerical control machine tool fast braking device, comprise main spindle box, in described main spindle box, main shaft is installed, on described main shaft, be installed with magnetic conduction brake disc, on described main spindle box, braking bracket is installed, brake is installed on described braking bracket and controls oil cylinder, the output control connection that oil cylinder is controlled in described brake has a pair of brake clamp that is positioned at described magnetic conduction brake disc both sides, between a pair of described brake clamp, be connected with elastic recovery device, on described brake clamp, be also provided with magnetic force adsorption apparatus.
As preferred technical scheme, described elastic recovery device comprises compression spring leaf.
As the improvement to technique scheme, described magnetic force adsorption apparatus comprises a pair of magnetic-adsorption piece attracting each other being arranged on described brake clamp.
As the further improvement to technique scheme, in a pair of described magnetic-adsorption piece, at least one of them is permanent magnet.
Owing to having adopted technique scheme, main shaft of numerical control machine tool fast braking device, comprise main spindle box, in described main spindle box, main shaft is installed, on described main shaft, be installed with magnetic conduction brake disc, on described main spindle box, braking bracket is installed, brake is installed on described braking bracket and controls oil cylinder, the output control connection that oil cylinder is controlled in described brake has a pair of brake clamp that is positioned at described magnetic conduction brake disc both sides, between a pair of described brake clamp, be connected with elastic recovery device, on described brake clamp, be also provided with magnetic force adsorption apparatus.During work, described magnetic conduction brake disc rotates with described main shaft, when the motor of Digit Control Machine Tool stops operating, described brake is controlled oil cylinder and is controlled described brake clamp clamping, the magnetic adsorbability of described magnetic force adsorption apparatus, described brake clamp is adsorbed on described magnetic conduction brake disc, increased the frictional force between described brake clamp and described magnetic conduction brake disc, described main shaft is stopped operating fast, described main shaft is the reset of described brake control oil cylinder after stopping operating fast, and described brake clamp resets under the effect of described elastic recovery device.The utility model makes fast main shaft stop the rotation when motor quits work, and saves time, and increases work efficiency, and simple in structure, braking effect is good.
