Abstract
The utility model relates to a numerically controlled lathe component, in particular to a braking device of a numerically controlled lathe. The braking device of the numerically controlled lathe comprises a main shaft, and a brake pad, wherein the brake pad is fixedly arranged on the main shaft in a sleeved mode, the braking device of the numerically controlled lathe further comprises a braking air cylinder which is used for braking the brake pad, and the braking air cylinder and the brake pad are correspondingly arranged. The structure adopts a braking device after a middle shaft positioning of the numerically controlled lathe, when the main shaft needs to stop rotating at once, the braking air cylinder needs to be started only, thereby enabling the braking pad to stop rotating, and braking the main shaft, so when the middle shaft is positioned, the situation is prompt and deviation can not occur. The braking device of the numerically controlled lathe has the advantages of improving the stability during positioning of the middle shaft of the numerically controlled lathe and after positioning of the middle shaft, and enhancing the precision of production machining.
Description
Technical field
The utility model relates to a kind of numerically controlled lathe assembly, especially a kind of brake gear of numerically controlled lathe.
Background technology
Numerically controlled lathe is a kind of high accuracy, high efficiency automated machine tool.Be equipped with multistation cutter tower or power cutter tower, lathe just has widely technology capability energy, but the complex parts such as processing linear cylinder, oblique line cylinder, circular arc and various screw thread, groove, worm screw.Have linear interpolation, the various compensate functions of circular interpolation, and in the batch production of complex parts, brought into play good economic effect.
And Numeric Control Technology also is computer numerical control technology (CNC, Computerized Numerical Control), and it is the technology that adopts the computer realization Digital Program Control at present.This technology is carried out time sequential routine logic control function to movement locus and the peripheral hardware of equipment with computer by the control program of prior storage.Owing to adopting computer to substitute the numerical control device that originally formed with hardware logic electric circuit, make the realization of the various Control functions such as storage, processing, computing, logic judgement of input operation instruction, all can finish by computer software, process the microcosmic instruction that generates and send servo drive drive motors or the operation of hydraulic actuator drive equipment to.
But numerically controlled lathe in the market owing to lacking brake gear, in the spindle index location and the stability behind the main shaft orientation not high, affected the precision of product processing.
Summary of the invention
The purpose of this utility model is, provide a kind of improve in the numerically controlled lathe axis calibration and calibration after stability, and improve the brake gear of the numerically controlled lathe of lathe in machining Product Precision.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of brake gear of numerically controlled lathe, comprise main shaft, brake block, the brake block fixed cover is located on the main shaft, also comprises the brake cylinder for braking brake block, brake cylinder setting corresponding to brake block.
Of the present utility modelly further be set to: comprise that also main spindle box, main shaft are arranged on the main spindle box, brake block is a disk, is set on the main shaft.
Of the present utility modelly further be set to: comprise that also support, main spindle box are fixedly installed on the support, brake cylinder is fixedly installed on the support, and with the main shaft adjacency.
Of the present utility modelly further be set to: described brake cylinder is provided with a brake groove adaptive with brake block, and the peripheral edge portion of brake block is positioned at the brake groove.
Of the present utility modelly further be set to: described brake groove is a U-shaped groove, and the brake block peripheral edge portion is positioned at U-shaped groove.
Said structure adopts the brake gear after the axis of numerically controlled lathe is located, when the needs main shaft stops operating immediately, as long as aerodynamic brake cylinder, brake block is stopped operating, thereby to principal shaft braking, so when axis is located, just very timely, and deviation can not appear, improved in the numerically controlled lathe axis location and the stability behind the axis location, thereby improved the precision of product processing.
Description of drawings
Fig. 1 is the structural representation of the present embodiment;
The specific embodiment
With reference to figure 1 brake gear of a kind of numerically controlled lathe of the utility model as can be known, comprise main shaft 2, brake block 5, brake block 5 fixed covers are located on the main shaft 2, also comprise the brake cylinder 1 for braking brake block 5, brake cylinder 1 and brake block 5 corresponding settings, brake cylinder 1 is not with gas-tpe fitting (gas-tpe fitting identifies in the drawings), main shaft 2 is arranged on the main spindle box 4, brake block 5 is a disk, be fixed on the main shaft 2 by screw is sheathed, main spindle box 4 one sides are fixedly installed on the support 3 by screw, brake cylinder 1 is fixedly installed on the support 3, is positioned at the top of main spindle box 4 spindle end outer walls, and with main shaft 2 adjacency, described brake cylinder 1 is provided with a brake groove 11 adaptive with brake block 5, the peripheral edge portion of brake block 5 is positioned at brake groove 11, and two-sided cylinder is arranged on the brake cylinder 1, and two-sided cylinder is relative, form a U-shaped groove, brake block 5 peripheral edge portions are positioned at U-shaped groove (in the middle of the cylinder of two sides).
The utility model utilization arranges brake gear at numerically controlled lathe, this brake device structure is simple, easy to operate, behind numerically controlled lathe axis location, in time brake, so just can guarantee in the numerically controlled lathe axis location with the axis location after stability, thereby improve the accuracy of lathe in machining product.
