Background technology
At present, for inner curve, external curve, the grinding machine tool as radial motor cam ring inner curve mainly contains optical contour grinder, grinding center and planer-type profile grinder.
The weak point of optical contour grinder is: 1. the on-line checkingi in process is detected by geometric optics, can not realize the quantification feedback of abrasion of grinding wheel.2. the feeding many employings ball-screw participating in interlock drives, easy to wear, and safeguard and comparatively bother, precision is lower.
The weak point of grinding center is: 1. participate in universal driving shaft too much, make to reduce the ground effect of external curve in specific high accuracy.2. rotary table is less, can not meet needs of production.
The weak point of planer-type profile grinder is: 1. planer type structure makes the waste of X-axis stroke over half, cause drive disk assembly and crossbeam long, make Stiffness and cost increases.2. the two column of planer type structure causes lathe bed to increase, and load-bearing increases, Stiffness and cost increase.
Summary of the invention
The grinding that the present invention is directed to inside and outside circle and interior external curve proposes a kind of employing cantilever beam structure, and application directly drives technology, collection on-line checkingi, the high precision numerical control grinding machine of online compensation function.
The technical solution used in the present invention is as follows.
1. rotary table (2) and column (3) are individually fixed on lathe bed (1), it is cantilever beam (4) above column, cantilever beam left end is ram (5), be emery wheel (6) and CCD checkout gear (7) below ram, electricity cabinet (8) is positioned at column both sides, forms one with base.
2. the X participating in processing adopts beam type structure to universal driving shaft, be line slideway auxiliary (9) between described cantilever beam (4) and upright post connecting plate (12), upright post connecting plate is fixed on column (3) top, cantilever beam is driven by linear electric motors (26), realizes closed-loop control by grating (11).
3. be line slideway auxiliary (14) between ram (5) and cantilever beam connecting plate (13), ram is driven by ball-screw (15), servomotor (16) is installed on a cantilever beam, ball-screw is driven by gear (10), it is inner that electro spindle is arranged on ram (5), and emery wheel (6) is by high-speed electric main shaft (17) Direct driver of band encoder.
4.CCD checkout gear (7) is by ccd video camera (18), support (19), rotating disc (20) and checkout gear shell (22) are formed, wherein ccd video camera (18) and light source generator (25) are arranged in checkout gear shell (22), and be fixed on rotating disc (20) by support (19), rotating disc is fixed on ram (5) bottom, rotatable 180 degree of CCD detection system, when behind in-position, fastening by wing bolt (21), the opening and closing of protective plate (24) are driven by steering wheel (23).
Structure of the present invention is simple, and reliability is high, and grinding quality is easy to ensure, and the feeding participating in interlock all adopts and directly drives technology, enables lathe solve the grinding of external curve in the higher middle-size and small-size part of required precision.
Beneficial effect of the present invention is as follows.
1. the present invention can realize the high-precision grinding of external curve in middle-size and small-size part, especially solves an accurate grinding difficult problem for radial plunger type motor cam ring inner curve.
2. lathe adopts the working method of 2 axle interlocks, and motion link is few, and complete machine rigidity is higher, and interlock precision is easily guaranteed.Lathe adopts beam type structure, saves stroke, reduces driver part length and improves the rigidity of beam.
3. linkage unit all adopts and directly drives technology, and namely rotary table is driven by torque motor, and X-axis feeding adopts linear electric motors to drive.
4. rotating CCD checkout gear can carry out on-line checkingi to emery wheel, can carry out online compensation by feedback to the wearing and tearing of emery wheel.Interchangeable blade electro spindle can clamping gage outfit, and lathe is detected without the need to secondary clamping Processing Curve.
