Abstract
A profile trimming device for grinding wheels of a grinder comprises a diamond roller, a numerically-controlled cross feeding component and a roller spindle component. The diamond roller is a cone with the conical surface and the large-end sharp corner thereof densely covered with diamond grains, and the diamond roller is mounted at the output shaft end of the roller spindle component through a central cylindrical hole and an end face. The numerically-controlled cross feeding component comprises a numerical control movement X-axis and a numerical control movement Z-axis perpendicular to each other, and the Z-axis is parallel to an axis of a to-be-trimmed grinding wheel. The roller spindle component is mounted on a table top of the numerically-controlled cross feeding component, and an axis of the roller spindle component forms a certain angle with the Z-axis of the numerically-controlled cross feeding component, and intersects with the axis of the grinding wheel in a coplanar manner. The profile trimming device is high in trimming precision, high in trimming speed and strong in universality, matches with a numerical control grinding machine tool and can meet requirements on efficient automatic production of high-precision, multi-variety and complex parts.
Description
Technical field
The utility model relates to a kind of grinder wheel linear accurate trimming device arbitrarily, be a kind of work taper seat that adopts conical diamond roller specifically, move along the cone element direction by numerical control diaxon INTERPOLATION CONTROL OF PULSE, realization is accurately repaired the emery wheel linear surface, and by conical diamond roller tune is installed, adopt the big end wedge angle of conical diamond roller to carry out the accurate finishing of emery wheel curvilinear surface, be mainly used in cylindrical grinder, form grinder etc. and carry out the on-line automatic finishing of emery wheel.
Background technology
The lathe equipment is subjected to the great attention of countries in the world as strategic industry all the time, and Precision Machining is all the more so.The grinding lathe is as a kind of typical precision finishing machine, and its development level has represented the conventional lathe equipment of a country to a certain extent.
In order to realize the operate as normal of grinding lathe, one of its basic requirements is exactly the online finishing of emery wheel.The online finishing of emery wheel of lathes such as present various cylindrical grinders, grinding machine of universal, internal grinder generally all is to utilize the diamond pen instrument to rely on the motion of lathe to realize, there is certain problem in this mode, as diamond pen tool head quick abrasion, trimming wheel geomery error is big, thereby causes accessory size control difficulty; Have and can only repair linear profile, just helpless for profiled surface, the technological ability of lathe is restricted.Therefore present this crushing technology dressing accuracy is low, repairs linear singlely, can't satisfy the requirement that the high-efficient automatic of high accuracy, many kinds, complex parts is produced.
Summary of the invention
The purpose of this utility model aims to provide a kind of grinder wheel linear accurate trimming device arbitrarily, realizes the on-line automatic finishing of emery wheel, effectively overcomes the dressing tool wear problem, thereby solves processing parts precision and stability problem thereof.
The utility model is achieved through the following technical solutions:
A kind of grinder wheel profile trimming device, it comprises diamond roller, numerical control cross infeed mean, roller spindle unit; Described diamond roller is one conical and be densely covered with diamond grit at its conical surface and big end sharp corner, and it is installed in the output axle head of roller spindle unit by center cylindrical hole and end face; Described numerical control cross infeed mean comprises two orthogonal digital control kinematic axis of X, Z, its Z axle with treat that the axis of trimming wheel is arranged in parallel; The roller spindle unit is installed on the table top of numerical control cross infeed mean, the angled layout of Z axle of its axis and numerical control cross infeed mean, and coplanar crossing with the axis of emery wheel.
The angular range of the Z axle of the axis of roller spindle unit of the present utility model and numerical control cross infeed mean is 0 °-45 °.
The utlity model has following advantage:
The utility model adopts conical diamond roller as dressing tool, move along two relative 180 ° on conical surface generatrix directions by numerical control diaxon INTERPOLATION CONTROL OF PULSE, realization is to the accurate meticulous finishing of angle emery wheel linear surface, by conical diamond roller tune is installed, use the big end wedge angle of diamond roller can also carry out the accurate finishing of emery wheel curvilinear surface.Package unit dressing accuracy height, trimming speed is fast, and highly versatile is supporting with the numerical control grinding machining tool, can satisfy the requirement of the high-efficient automatic production of high accuracy, many kinds, complex parts.

The specific embodiment
The utility model is further described with the specific embodiment by reference to the accompanying drawings in bottom.
As Fig. 1～shown in Figure 4, whole trimming device mainly comprises diamond roller 4, numerical control cross infeed mean 2, roller spindle unit 3, simply says to be exactly diamond power roller devices+two-axis numerical control Servocontrol device.Diamond roller 4 wherein is one conical and be densely covered with diamond grit at its conical surface and big end sharp corner, is installed in the output axle head of roller spindle unit 3 by center cylindrical hole and end face; Numerical control cross infeed mean 2 has two orthogonal digital control kinematic axis of X, Z, adopt typical rectilinear motion servo drive scheme, namely adopt rotary servovalve motor+ball screw to drive, linear rolling guide guiding, and according to required precision employing semiclosed loop or close-loop control scheme; Roller spindle unit 3 adopts built-in motor driving rolls or motor+shaft coupling live roller axle, also can adopt motor+belt transmission roller shaft.
The axis of the Z axle of numerical control cross infeed mean 2 and emery wheel 5 is arranged in parallel during practical application; Roller spindle unit 3 is installed on the table top of numerical control cross infeed mean 2, for the ease of the coupling of related angle, and the angled layout of Z axle of its axis and numerical control cross infeed mean 2, and coplanar crossing with the axis of emery wheel 5; The cone angle B of diamond roller 4 is identical with the included angle A that is trimmed the angle emery wheel.When finishing angle emery wheel, the conical surface of diamond roller 4 is outwards installed, as shown in Figure 3, can move along its two relative cone element direction this moment by 2 controls of numerical control cross infeed mean, the conical surface of dependence diamond roller 4 is repaired out the angle emery wheel of included angle A=B, since be that many diamond particles on the whole cone element of diamond roller 4 participate in finishing simultaneously, therefore, even under the fast feed situation, also can repair out fine-grained emery wheel working surface.When trimming curve profile emery wheel, the conical surface of diamond roller 4 is installed inwards, as shown in Figure 4, by the diaxon interpolation of numerical control cross infeed mean 2, relies on the big end wedge angle of the conical surface of diamond roller 4 to repair out any curved profile.
