Description
Technical field
This utility model is relevant with the scraping brushing device of ball screw, refers in particular to a kind of be easily installed and can prevent the scraping brushing device fixed form that false precompressed produces.
Background technology
Ball screw is the rolling utilizing ball, drive screw rod and nut relative displacement, and there is low friction and high-accuracy advantage, if having any dust or break flour to enter, will impact the effect of ball screw with precision, therefore dust prevention just becomes critically important；nullFor this，Develop many technology dust-proof about ball screw on the market，One of which is as shown in Figure 4，One scraping brushing device B in the form of a ring is set in one end of a nut A，This nut A is radially offering two relative screw A1，Assembly crewman must electric hand drill，This scraping brushing device B is deeply got out by drill bit from this screw A1 two to should the shrinkage pool C2 of screw A1，And lock with a screw A2 respectively and pass two this screw A1，Two this screw A2 support in this shrinkage pool C2 to fix this scraping brushing device B，This scraping brushing device B is made to be fixed in this nut A，In so rolling channel C1 of the screw rod C that the lip B1 of this scraping brushing device B just can be contained in this ball screw，When this ball screw start，The lip B1 of this scraping brushing device B can strike off the function of foreign body along with the generation in this rolling channel C1 that rotates of this screw rod C，Additionally，Can prevent dust or break flour from entering this rolling channel C1，This ball screw is allowed to be maintained under clean state，And can start accurately.
But after actually used, find that this kind of scraping brushing device B still has a following number of drawbacks:
One, installation personnel must use electric drill to process this shrinkage pool C2, cause the prolongation of assembling time-histories, and it is unexpected easily to produce industrial injury, furthermore this electric drill adds drilling produced by man-hour and also can fall into inside nut, totally then influence whether the smooth degree that ball screw runs without cleaning, the most then cause damage.
nullThey are two years old、This scraping brushing device B is when installing，But should with this screw rod C be maintained at extremely close to not in contact with position，It is only optimal state，But sealed power and the degree of depth are quite difficult to be controlled，If the degree of depth that two this screw A2 lock this screw A1 is the deepest，This scraping brushing device B can be oppressed by both sides，The lip B1 making this scraping brushing device B oppresses the rolling channel C1 of this screw rod C and produces false precompressed [note: false precompressed refers to not screw rod to ball screw、The adjustment of the catch cropping precompression of nut and ball，But the active force of this rolling channel C1 is oppressed because of this lip B1，Allow user be mistakenly considered ball screw and there is precompression，But this precompression is temporary，Because after this lip B1 such as wears away with rolling channel C1，This precompression will disappear and then draw the precision that the equipment that rings runs]，When this screw rod C rotates，This lip B1 will not stop friction in this rolling channel C1，The material of this scraping brushing device B is the hardness such as the plastic cement material less than metal mostly，When not stopping friction，This lip B1 will deform because of high delivery in hot weather heat，Or it is grated generation dust，The damage or the dust that cause this scraping brushing device B affect the problems such as start precision.Therefore this scraping brushing device B there are still disappearance the most to be solved, and the design people is just improved for this.
Utility model content
Because the problems referred to above, this utility model main purpose is: after researching and developing a kind of scraping brushing device fixed structure being easy to assemble and avoiding assembling, scraping brushing device produces false precompression.
For reaching above-mentioned purpose, solution of the present utility model is:
A kind of ball screw having scraping brushing device, comprises: a screw rod, and it extends for strip structure towards a direction, and defining this prolonging direction is direction of principal axis, and the outer edge surface of this screw rod is provided with spiral helicine rolling channel；One nut, it has the through hole that this screw rod of confession is sheathed, and the inner edge surface of this through hole is provided with the rolling groove of this rolling channel relatively, and this rolling channel and rolling groove constitute a load path, this through hole be respectively arranged at two ends with a mounting groove, the outer edge surface of this nut runs through multiple screw connected with this mounting groove；This load path is located at by multiple rolling elements；Two scraping brushing devices are respectively arranged on two these mounting grooves, and this scraping brushing device is circulus, in inner ring surface be provided with to should the lip of rolling channel, be provided with an annular recess in outer ring surface, this groove be provided with elastic component；After multiple screw spiral shells are located at this screw, the end of this screw contacts at this elastic component, limits rotation and the direction of principal axis degree of freedom of this scraping brushing device whereby.
Further, the thickness of this elastic component is the 1/2 optimal of this depth of groove.
After using said structure, this utility model arranges this elastic component by the groove of this scraping brushing device, this groove is utilized to replace conventional bore operation, and this screw has limited the direction of principal axis degree of freedom of this scraping brushing device when stretching in this groove, but because this groove is annular recess, therefore and the rotary freedom of this scraping brushing device cannot be limited, therefore, this utility model is by the setting of this elastic component, when making this screw contact at this elastic component, can reach to limit the effect of this scraping brushing device rotary freedom, furthermore, when screwed lock too tight, this elastic component can sponge its locking force, without allowing this locking force be transferred to the lip of scraping brushing device, therefore it is avoided that the problem of false precompressed produces, therefore the problem solving prior art that this utility model is complete.
