Description
Technical field
The invention belongs to the precision measurement field, be specifically related to a kind of micromatic setting that is used for three coordinate measuring machine.
Background technology
When the machine-building of carrying out industries such as mould, Cellphone Accessories, stamping parts, clock and watch, auto-parts, detection or research and development; Requirement to the quality of workpiece and precision is more and more high; Need accurately measure the coordinate of the x that puts on the surface of the work, y, three directions of z, this just needs to use three coordinate measuring machine (claiming three-dimensional amount bed again).Three coordinate measuring machine mainly comprises on the worktable, data processor, worktable of level measurement axis that on support that x, y direction move and support, moves in the z direction etc., and the lower end of measurement axis is gauge head fixedly.Workpiece for measurement is placed on the worktable, and the gearing of x direction makes measurement axis and gauge head on support and the support move in the x direction on the worktable, and this moment, worktable was a base, and support is a moving component; The gearing of y direction makes measurement axis and gauge head on support and the support move in the y direction on the worktable, and this moment, worktable was a base, and support is a moving component; The gearing of z direction makes measurement axis and gauge head move in the z direction on the support, and this moment, support was a base, and measurement axis is a moving component.After gauge head senses surface of the work point, promptly transmit signal, gauge head is measured in the displacement of three directions, and data processor calculates the coordinate of surface of the work point, to judge dimensional accuracy, bearing accuracy, geometric accuracy and the contour accuracy etc. of workpiece.
For satisfying high-accuracy measurement needs, all be provided with accurate transmission mechanism in x, y, three directions of z, finely tune with motion gauge head.Micromatic setting commonly used at present is a leading screw, but will reach micron-sized precision drive, need leading screw is carried out retrofit, and complex structure, processing cost is high.
Summary of the invention
The present invention provides that a kind of processing cost is low, the micromatic setting that is used for three coordinate measuring machine of reliable transmission.
For achieving the above object, the technical scheme that the present invention adopts is: the related content in the technique scheme is explained as follows: a kind of micromatic setting that is used for three coordinate measuring machine, and said three coordinate measuring machine mainly comprises base and moving component; It is characterized in that: said micromatic setting mainly comprises polished rod and nut apparatus, and said polished rod and base are rotationally connected, and said nut apparatus comprises a housing; This housing is fixedly connected with said moving component; Said polished rod passes from housing, on this housing, is provided with at least three rollers, and said roller evenly is arranged at said polished rod week laterally; One is moving roller in the said roller; All the other are quiet roller, and the wheel shaft of said quiet roller is fixedly connected with housing, and the wheel surface of said quiet roller contacts with polished rod; One screw-down and said housing are slidingly connected, and this screw-down can be along moving perpendicular to the axial direction of polished rod; Said screw-down has power unit, drives the axle motions that this screw-down promotes said moving roller, makes the wheel surface butt polished rod of said moving roller; The wheel axis of said roller all has a bias angle theta with respect to the axis of polished rod, and this bias angle theta makes polished rod clamped by roller and the polished rod friction force that polished rod is applied to roller when rotating has one and is parallel to the axial component of polished rod.
1, in the such scheme; Said screw-down mainly comprises cylinder, spring and pressing block; Said pressing block and housing are slidingly connected, and this pressing block can be along moving perpendicular to the direction of polished rod axis, and the wheel shaft of said moving roller is fixedly connected with an end of pressing block; The piston action of said cylinder is in the direction perpendicular to the polished rod axis; The other end of said pressing block is fixedly connected an end of said piston, is provided with said spring between the other end of said piston and the housing, and said spring action is on the direction that compresses to the polished rod axis normal.
2, in the such scheme, the rod end of said polished rod has handwheel.
Principle of work of the present invention is: in the time of need not finely tuning, the cylinder ventilation makes piston drive pressing block away from polished rod, and the Piston Compression spring, and the wheel surface of the moving roller that pressing block connects does not contact with polished rod, and quiet roller, moving roller do not have clamping action to polished rod jointly; When needing fine setting, gas is discharged in the cylinder, and the stretching, extension promotion cylinder piston of spring drives pressing block and moves towards polished rod; The wheel surface that pressing block drives moving roller compresses to polished rod; Moving roller, quiet roller clamp polished rod jointly, produce friction force between polished rod and roller when polished rod rotates, and rely on the friction force polished rod to drive roller and rotate together; The wheel axis of roller has a bias angle theta with respect to the axis of polished rod; This bias angle theta makes polished rod clamped by roller and the polished rod friction force that polished rod is applied to each roller when rotating has one and is parallel to the axial component of polished rod, the core wheel of roller is moved, because the wheel shaft of roller is fixed on the housing of nut apparatus with respect to polished rod; The housing of nut apparatus is fixedly connected with moving component again; Therefore moving component moves with respect to polished rod, and radius, the rotating speed of polished rod and the size of bias angle theta of control polished rod realize the control to moving component fine setting degree.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
1, because the present invention works as rotating speed one timing of the radius and the polished rod of polished rod; Moving component is determined by the bias angle theta of the roller axis in the nut apparatus with respect to the polished rod axis with respect to the translational speed that is the fine setting degree of polished rod; The size that promptly only need adjust this bias angle theta just can be controlled the degree of fine setting; The manufacturing of nut apparatus requires to reduce, and can save processing cost.
2, since in the roller of the present invention one be moving roller, all the other all be quiet roller, thereby each roller asynchronous phenomenon that causes gearing to skid of moving, reliable transmission can not occur.
