Abstract
The utility model relates to a flexible pneumatic nut used for a three-coordinate measuring machine, which comprises a shell, bearings and air bearings, wherein the bearings and the air bearings are uniformly distributed in the circumferential direction of the inner wall of the front end of the shell to form clamping holes for polished rods to penetrate. The nut also comprises a tetrafluoroethylene flexible sleeve which is embedded in the circumferential direction of the inner wall of the rear end of the shell and is communicated with the clamping holes. The utility model solves the problems that friction and noise are caused because the inner diameter of the clamping hole of the pneumatic nut in the prior art is larger than the diameter of the polished rod and the polished rod easily deflects from the center of the clamping hole in the processes of installing and debugging the polished rod and moving each shaft. The utility model has simple structure and low cost, and is easy to manufacture and convenient and reliable to use.
Description
Technical field
The utility model relates to three coordinate measuring machine, relates in particular to a kind of flexible pneumatic nut of using with the manual three coordinate measuring machine of polished rod fine setting.
Background technology
Three coordinate measuring machine be a kind of have can make the detector that three directions move, this detector is gone up at three orthogonal guide rails (X, Y, Z axle) and is moved, and transmitting signal with contact or mode such as noncontact, the displacement measurement system of three axles (as the optics chi) calculates each point coordinate (X, Y, Z) of workpiece and dimensional accuracy, bearing accuracy, geometric accuracy, contour accuracy through data processor or computing machine etc.
Three coordinate measuring machine comprises pedestal, worktable and detector, and worktable is divided into upper and lower two parts, and detector is made up of detecting head and detection headstock.Between worktable bottom and the pedestal between (X-direction), worktable top and the worktable bottom between (Y direction) and detecting head and the detection headstock (Z-direction) adopt respectively that the rectilinear orbit of being made up of pneumatic nut and polished rod is secondary to be connected, so that the worktable bottom can be moved along X-direction, worktable top then can be moved in Y direction relative to the worktable bottom, and detecting head then can move in Z-direction relative to the detecting head pedestal.
At present, the structure of pneumatic nut commonly used such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4 on the three coordinate measuring machine, form by housing 1, two bearings 2 and an air bearing 3, two bearings 2 and air bearing 3 act on the holes for clamping 4 of polished rod 5 along circumferential uniform formation in the front side of housing 1 inwall, polished rod is arranged in the holes for clamping 4.When giving air bearing 3 ventilations, holes for clamping 4 internal diameters increase, and unclamp polished rod 5, and pneumatic nut can move along polished rod is smooth and easy, makes three (X, Y, Z axles) relatively move freely; When dying for air bearing 3, holes for clamping 4 internal diameters dwindle, and hold polished rod tightly, make three (X, Y, Z axle) relative fixed.But because holes for clamping 4 is made of two bearings 2 and air bearing 3 amalgamations, its internal diameter size makes that greater than the polished rod diameter when Installation and Debugging, polished rod is arranged in the center of wherein easily departing from holes for clamping 4, and is difficult to adjust.In addition, in three (X, Y, Z axle) moving process, air bearing 3 is ventilated, and the internal diameter of holes for clamping 4 increases, and makes pneumatic nut when polished rod moves, easily rub, and the generation noise.
Therefore, how addressing the above problem, is the content that the utility model important research.
Summary of the invention
The utility model provides a kind of three coordinate measuring machine flexible pneumatic nut, its objective is that the relative polished rod diameter of holes for clamping internal diameter that solves pneumatic nut in the prior art is bigger, in polished rod Installation and Debugging and each moving process, polished rod easily departs from the holes for clamping center, thereby brings the problem of friction and noise.
For achieving the above object, the technical solution adopted in the utility model is: a kind of three coordinate measuring machine flexible pneumatic nut, comprise housing, bearing and air bearing, described bearing and air bearing act on the holes for clamping of polished rod in the uniform formation that makes progress in the week of housing front inner wall, also comprise a tetrafluoroethene flexible boot, the week that this tetrafluoroethene flexible boot is embedded at housing rear end inwall makes progress, and is communicated with holes for clamping.
Related content in the technique scheme is explained as follows:
1, in the such scheme, the internal diameter of described tetrafluoroethene flexible boot and the external diameter of described polished rod are complementary, and make to work as to the air bearing ventilation, when pneumatic nut moves along polished rod, polished rod can not be offset in the tetrafluoroethene flexible boot, has avoided the friction between polished rod and each bearing.And polished rod is when Installation and Debugging, is easy to be adjusted in the holes for clamping in the heart.
2, in the such scheme, described bearing and air bearing are at least three, and its centre bearer is at least two, and air bearing is at least one.
3, in the such scheme, the center line of described tetrafluoroethene flexible boot and the central lines of holes for clamping.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, the utility model is embedded a tetrafluoroethene flexible boot in pneumatic nut inner walls rear end, when polished rod being arranged in the holes for clamping of pneumatic nut, pass this tetrafluoroethene flexible boot simultaneously, because the internal diameter of this flexible boot and the external diameter of polished rod coupling, make pneumatic nut on polished rod when mobile, polished rod can not be offset again, and friction no longer appears between each bearing, produce noise, and, solved the problem that the polished rod that occurs and pneumatic nut right alignment are difficult to adjust in debug process to the not influence of the precision of pneumatic nut own.
2, the utility model is simple in structure, makes easily, and cost is low, and is easy to use and reliable.
