Numerical control automatic tooth profile strength forming grinder

Abstract

The invention discloses a numerical control full-automatic tooth-profile strength molding grinder, which comprise a grinder body, a working table, a grinding head, a grinding wheel dresser, an automatic feeding mechanism, a grinding head transverse feeding mechanism, a grinding head vertical feeding mechanism, a clamp, a work piece fixed-length feeding device, a medium pressure and large flow cooling and lubricating and high pressure washing pumping station, a precise filter and a numerical control system. In the invention, the grinding wheel dresser is arranged at the back of the working table; when a machine tool is arranged at the position of stop working, the grinding wheel is positioned between the working table and the grinding wheel dresser, and does not touch the work piece and the dresser; when the machine tool is grinding, the grinding wheel moves in working feed forward, and grinds the work piece in strength molding; when the grinding wheel needs dressing, the grinding wheel moves backward and passes through the grinding wheel dresser to finish the dressing and the depth control of the machining dimension, therefore the dimension of the grinding wheel changed by the dressing will not influence the machining precision. The machine tool can finish a full-automatic cycle movement through a four or five-axis numerical control system.

Description

Technical field [0001] The invention relates to a grinder, in particular to a powerful forming grinder with processing and forming capabilities. Background technique [0002] All kinds of saw blades and saw blades are necessary tools in the cutting process. They have a large volume and a wide range. The traditional saw teeth are processed by a milling machine. The smoothness of the saw teeth is poor and the tooth tips are not sharp. (Cutting edge arc ≥ 0.1 mm) has burrs, so it is prone to undesirable phenomena such as tooth pull and saw deviation, which seriously affects the service life of the saw blade. [0003] Various racks are a kind of mechanical parts widely used in mechanical linear motion mechanisms. They are usually processed by milling, inserting, or hobbing. However, high-precision racks need to be refined with a grinder after the above-mentioned processes are processed and formed. Machining (requiring two types of machine tools for group processing, time-consuming, h...

Problems solved by technology

However, the structure of this device is complicated, and the supporting structure of the dressing wheel is less rigid.

[0007] For the powerful forming grinder, although the grinding wheel has good retention, it can grind several batches of workpieces continuously after dressing the grinding wheel once, but it also needs to dress the grinding wheel, so these two types of grinding wheel dressers are obviously not applicable.
