Abstract
The utility model discloses a grinding carriage feed system of a grinding machine. The grinding carriage feed system of the grinding machine comprises a grinding carriage which is matched with a rack to achieve a lateral movement through a V-shaped flat guide rail, and the grinding carriage is connected with the rack through a guide rail reversed fasten device. The feed mechanism of the grinding carriage is formed by an alternating current servo motor which is transmitted to a precise ball screw pair through a reduction gear, and the precise ball screw pair is installed on the rack. The grinding carriage of the grinding carriage feed system of the grinding machine moves laterally (X-axis), and the grinding carriage feed system of the grinding machine adopts a hydrostatic lubrication and a rigid structure as much as possible, and adopts the V-shaped flat guide rail at the same time so as to achieve an absolute directional stability which is independent of a vertical cutting force, and the balance of any possible thermal expansion is guaranteed. The guide rail reversed fasten device designed in the grinding carriage feed system guarantees the advantages of high precision and high stability, the grinding carriage feed system has high load grinding capability, large grinding carriage journey, and is capable of grinding big rollers and small rollers, and is suitable for roller diameter changes of larger range, and the effective processing range of the grinding machine is enlarged.
Description
Technical field
The utility model discloses a kind of grinder wheel frame feed system, divides by International Patent Classification (IPC) (IPC) to belong to numerical control frosted equipment manufacturing technology field.
Background technology
The grinding carriage feed system of numerically control grinder must have good dynamic property, rigidity, repeat to transport a precision and very strong antivibration characteristic etc., the driven by servomotor ball screw of traditional structure add rail plate or rolling guide form oneself through satisfying fully.The key of grinding carriage feed system is structure and the type of drive of guide rail, present similar lathe adopts Rectangular Hydrostatic rail plate or cylindrical static pressure rail plate usually, the rigidity of this class guide rail and antivibration characteristic are good, shortcoming is complicated in mechanical structure, manufacture difficulty is large, and also very high to the requirement of guide rail lubricating system.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, reliable grinder wheel frame feed system stably.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of grinder wheel frame feed system, comprise grinding carriage, this grinding carriage cooperates with frame by the V flat type guide rail realizes transverse shifting, and the feed mechanism of grinding carriage is transferred to the precise ball screw pair by AC servo motor through deceleration device and forms, and described precise ball screw pair is installed on the frame.
Further, described grinding carriage is assemblied on the frame by the V flat type rail engaging structure, and grinding carriage links to each other with frame by guide rail left-hand thread device.
Further, described guide rail left-hand thread device comprises L shape press strip, this press strip one end is fixed on the frame by screw, and the press strip other end places in the fit of the grinding carriage guide rail outside, and described grinding carriage cooperates by the linear grating location and with AC servo motor realizes grinding carriage closed loop Position Control.
Further, the secondary two ends of described precise ball screw are installed on the frame by the bearing that matches, and the secondary end of precise ball screw extends to frame outward and the energy shaft coupling links to each other with reductor and AC servo motor, and the power of realizing grinding carriage is carried.
Grinding carriage transverse shifting of the present utility model (X-axis) adopts hydrostatic lubrication and rigid structure as much as possible, adopts simultaneously the V flat type guide rail reaching directional stability absolute, that be independent of straight-cut power, and guarantees the balance of any possible thermal expansion.The guide rail left-hand thread device of the utility model design guarantees its high-precision and high-stability advantage, has the high load capacity grinding capacity, larger mill frame stroke is arranged, but the roll that grinding is large and little is applicable to wider roller diameter and changes, and effective range of work of grinding machine obtains increasing.
