Abstract
The utility model discloses a lead screw nut transmission mechanism for a measuring machine. The lead screw nut transmission mechanism for the measuring machine comprises a sliding plate, wherein the sliding plate is erected on a guide rail by a sealed air floater; the middle part of the sliding plate is connected with a ball screw by a connecting plate and the sealed air floater; a lead screw nut is arranged on the ball screw in a sliding manner; a transmission plate is fixedly connected above the lead screw nut; the transmission plate is packaged in the sealed air floater; and the transmission plate and the sealed air floater are cooperatively connected and are synchronously moved. The lead screw nut transmission mechanism for the measuring machine is simple in structure, convenient to use, capable of reducing the influences of lateral transmission force to the moving part and capable of improving the moving precision of a moving piece.
Description
Technical field
The utility model belongs to fields of measurement, is specifically related to a kind of measuring machine screw nut driven mechanism.
Background technique
Synchronous cog belt is adopted in transmission in existing three coordinate measuring machine more, gear rack, ball screw and feed rod etc., and complex structure, adjustment requires highly difficult large.Measuring machine belongs to high precision measuring instrument, and is high to the transmission requirement, requires the driving force direction parallel with the guide rail direction, if not parallel meeting produces lateral force, affects the measuring machine precision.Especially gear rack, ball screw and feed rod, self lateral rigidity is high, if adjust bad larger on the measuring machine impact.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of measuring machine and uses screw nut driven mechanism, and is simple in structure, easy to use, reduced the impact of transmission lateral force on moving member, improves the moving part mobile accuracy.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of measuring machine screw nut driven mechanism, comprise: a slide plate, described slide plate is set up on guide rail by sealing air supporting, slide plate middle part is by joining plate and be connected air supporting connection one ball screw, feed screw nut is slidably mounted on ball screw, described feed screw nut top is fixedly connected with driver plate, and described driver plate is packaged in sealing air supporting, and driver plate is connected and is synchronized with the movement with sealing air supporting.
Preferably, described ball screw two ends are arranged on the guide rail bottom by bearing support, and are provided with linear rail in the ball screw bottom, and ball screw is slidably connected by slide block and linear rail, and described slide block is arranged at the driver plate bottom.
By technique scheme, the beneficial effects of the utility model are:
1) kept the driving force of ball screw driving direction;
2) improved ball screw and adjusted precision, feed screw nut does not directly connect with slide plate, has reduced the impact of transmission lateral force on moving member, improves the moving part mobile accuracy.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Fig. 3 is partial enlarged drawing of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
With reference to Fig. 1, Fig. 2 and shown in Figure 3, a kind of measuring machine use screw nut driven mechanism, comprising: a slide plate 1, and described slide plate 1 is set up on granite guide rail 3 by sealing air supporting 2, and slide plate 1 can move along ball screw 4 directions on granite guide rail 3.
When ball screw 4 axis and granite guide rail 3 when not parallel, the lateral force of generation can be eliminated without frictional movement perpendicular in ball screw 4 axis (slide plate movement direction) planes on sealing air supporting 2 interior edge by driver plate 7.Guarantee the precision that slide plate 1 moves on granite guide rail 3.
Be arranged on ball screw 4 following linear rail 9 and slide blocks 10 and can prevent that feed screw nut 6 is along ball screw 4 axial rotation.
Above demonstration and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
