Brief description of the drawings
Fig. 1 is a kind of structural representation of protection mechanism at three coordinate measuring machine Auxiliary support leg of the present invention；
Fig. 2 is the enlarged drawing of part A in Fig. 1.
Embodiment
It is the specific embodiment of the present invention and with reference to accompanying drawing below, technical scheme is further described,
But the present invention is not limited to these embodiments.
Existing three coordinate measuring machine Auxiliary support leg is easily bumped against and influences the measurement accuracy of three coordinate Auxiliary support legs,
The protection mechanism being used for for this present invention design one at three coordinate measuring machine Auxiliary support leg 8.
Such as Fig. 1, the protection mechanism is located at granite surface plate 1, and the side of granite surface plate 1 opens up downwards from its end
There is a breach 2.The protection mechanism includes case 3, fixture 4.The case 3 is formed in one, compared to the case of split
For, block dust and other effects more preferably；The case 3 is placed in the breach 2, the case 3 have from its upper surface to
Under the holding tank 31 that opens up, the support shaft adjustment bolt 5 and support shaft that Auxiliary support leg lower end is accommodated in the holding tank 31 adjust
Air bearing 6 below whole bolt.Wherein, minimum widith of the opening of the holding tank 31 less than the air bearing 6.So
Support shaft adjustment bolt 5, air bearing 6 will not be collided, and then influence the stability and three-dimensional coordinates measurement of Auxiliary support leg
The measurement accuracy of machine.
Specifically, the holding tank 31 includes being used for the first accommodating area 311, the Yi Jiyong for housing support shaft adjustment bolt 5
In the second accommodating area 312 of accommodating air bearing 6.In order to adapt to the size of support shaft adjustment bolt 5 and air bearing 6, and keep away
Exempt from dust to fall into, the width of first accommodating area 311 is less than the minimum widith of the second accommodating area 312.Further, described
Two accommodating areas have the space being adapted with air bearing size, and leave gap between the two.So that both adjustment,
There is certain activity space during effect.
For ease of assembling, safeguarding, the case 3 also has divides trisection located at the bottom surface of case 3（Not shown in figure）, it is described
Case is divided into two parts by point trisection, and one part divides trisection to be connected with another part by described, is divided by dividing trisection
Two parts can volume it is equal, also can volume it is unequal, designed in order to the mode of assembling.Also, in the granite surface plate 1
The lower section of breach 2 is provided with a combination block 7, and the combination block is detachable to be that granite surface plate 1 assembles, combination block 7 and flower after assembling
Both hilllock rock platforms can provide a flat surface for the bottom surface of case 3, to support case 3.Especially, when dividing trisection to be located at case
3 bottom surfaces, and when above the region of combination block 7, when combination block 7 is withdrawn, due to dividing trisection so that case 3 is close
The part of the avris of granite surface plate 1 to combination block it is original where spatial rotational；Once combination block 7 is assemblied in granite surface plate 1
When together, combination block 7 supports case 3 close to the part of the avris of granite surface plate 1.That is, when the combination block 7 and flower
After hilllock rock platform 1 separates, a part of the case 3 close to the side of granite surface plate 1 is put down relative to another part in granite
Platform 1, which lacks in the space of combination block 7, to be rotated；After the combination block 7 combines with granite surface plate 1, the fixture 4 is by described in
Case 3, the combination block 7 and the three of granite surface plate 1 fix.As illustrated, fixture 4, such as screw, the combination block
7 be corner block, and case 3 is placed in breach 2, and combination block 7 combines assembling with granite surface plate 1 to support case 3, fixture 4
Case 3, combination block 7, granite surface plate 1 are fixed jointly in vertical direction.So, only using a complete case,
One fixture can be achieved with anticollision, put the effect of dust, simple in construction.
Combinations thereof block 7 is not limited to corner block, can also be trapezoid block, and it is inclined-plane with the contact surface of granite surface plate 1.
The combination block 7 and the fixed form of granite surface plate 1 realize that such as described combination block 7 is provided with tenon, the flower in the form of fixing
Hilllock rock platform 1 is provided with groove on the contact surface being connected with the combination block 7, and the groove fixes with the tenon to be coordinated.
It is no matter how small in view of the opening of storage tank 31, there is certain dust to fall into.For this at support shaft adjustment bolt end
Portion is provided with flexure strip 32, and the neck 3111 of the accommodating flexure strip 32 is offered in first accommodating area 311.In order that flexure strip
32, which stretch into neck 3111, is not easily disconnected from, and an embodiment is, the flexure strip 32 is metallic elastic piece, in the neck 3111
Particle is inhaled with magnetic.Another embodiment is that the flexure strip 32 is metallic elastic piece, there is upper surface in the neck 3111
Magnetic absorption coating.So, metallic elastic piece is adsorbable in neck 3111, avoiding dust, while the structure is easy to disassemble.
It should be understood by those skilled in the art that the embodiments of the invention shown in foregoing description and accompanying drawing are only used as illustrating
And it is not intended to limit the present invention.The purpose of the present invention completely effectively realizes.The function and structural principle of the present invention is in reality
Apply and show and illustrate in example, under without departing from the principle, embodiments of the present invention can have any deformation or modification.
