Abstract
The utility model discloses an adjusting bolt of a three-coordinate measuring machine, which is used for connecting an air floating block and a moving element. The adjusting bolt is characterized by comprising a front end propping head, a thread main body, a hexagon socket bolt and a papilionaceous elastic gasket, wherein the end part of the propping head is V-shaped and concaved, and shaft diameter of the rear section is smaller than shaft diameter of the front section; the thread main body is provided with a central through hole, a gasket hole is arranged in the through hole, and the front end propping head is in clearance fit with the through hole of the thread main body; the hexagon socket bolt penetrates the gasket hole of the thread main body and is in threaded connection with the front end propping head, and the end part of the hexagon socket bolt is propped against the other side of the gasket hole; and the papilionaceous elastic gasket is sleeved on the rear section shaft of the front end propping head and placed between the front section shaft of the propping head and the thread main body. The adjusting bolt enables the air floating block to be more closely jointed on a guiding rail, and can be used when the moving element is not parallel with the guiding rail at the same time.
Description
Technical field
The utility model relates to a kind of adjustment bolt of three coordinate measuring machine, particularly relates to a kind of highi degree of accuracy guide rail that is used for three coordinate measuring machine, guarantees the adjustment bolt that has tension of lathe straightness accuracy.
Background technique
Three coordinate measuring machine is a kind of accurate surveying instrument, and its guide rail must have accurate straightness accuracy, simultaneously, allows moving element critically be fitted on the guide rail again.Particularly three-coordinate precision than higher measuring machine in, have only the gap of 3 microns steam films of one deck between its guide rail and the air supporting piece.This just makes moving element closely to be fitted on the guide rail.Prior art relies on the adjustment bolt that moving element closely is fitted on the guide rail, but because twist too deadly the air supporting piece is checked lock as the brake holding car easily, can not allow moving element move; And existing adjustment bolt does not have the aligning function, allows the air supporting piece tilt easily, causes the air emptying in it, does not form air film, and air supporting piece and granite guide rail are ground away.
The model utility content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and proposes a kind of adjustment bolt with certain elasticity and aligning function, can prevent effectively that air supporting piece and granite guide rail from grinding away, and prevent " locking " phenomenon.
The technological scheme that the utility model solution prior art deficiency is taked is: a kind of adjustment bolt of three coordinate measuring machine, connect air supporting piece and moving element, and it is characterized in that adjusting bolt and comprise:
One front end holds out against head, holds out against the V-shaped depression of cephalic par, and the back segment diameter of axle is less than the leading portion diameter of axle;
One threaded body, central through bore is established the pad hole in the through hole, and front end holds out against a Spielpassung in the threaded body through hole;
One hexagon socket head cap screw, the pad hole of passing threaded body holds out against head thread with front end and is connected, and comes off to prevent it, and interior hexagonal end withstands on pad hole opposite side;
One butterfly elastic washer is enclosed within front end and holds out against on the back segment axle of head, places to hold out against between a leading portion axle and the threaded body, plays the effect of tensioning.
The breech face of described threaded body is processed with straight groove, is used to adjust the degree of tightness of bolt.
The beneficial effects of the utility model are: front end holds out against head and threaded body Spielpassung, and be with the butterfly elastic washer, make and adjust bolt and have certain elasticity and aligning function, can prevent effectively that air supporting piece and granite guide rail from grinding away, and prevent " locking " phenomenon.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model assembly structure schematic representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
The adjustment bolt of a kind of three coordinate measuring machine of the utility model as shown in Figure 1 connects air supporting piece and moving element, adjusts bolt and comprises:
One front end holds out against 1, holds out against the V-shaped depression 5 of cephalic par, and back segment axle 7 diameters are less than leading portion axle 6 diameters;
One threaded body 4, there is through hole at the center, establishes pad hole 8 in the through hole, and front end holds out against a Spielpassung in the threaded body through hole;
One hexagon socket head cap screw 3, the pad hole of passing threaded body holds out against head thread with front end and is connected, and comes off to prevent it, and interior hexagonal end withstands on pad hole opposite side;
One butterfly elastic washer 2 is enclosed within front end and holds out against on the back segment axle of head, places to hold out against between a leading portion axle and the threaded body, plays the effect of tensioning.
The breech face of described threaded body is processed with straight groove 9, is used to adjust the degree of tightness of bolt.
The adjustment bolt as shown in Figure 2 and the assembly structure of air supporting piece and moving element when gas enters air supporting piece 11, are that 3 microns gap is arranged between granite guide rail 12 and the air supporting piece.As use existing common adjustment bolt, if twist too deadly, the air supporting piece can be checked lock as the brake holding car and can not allow moving element 10 move; And common adjustment bolt does not have the aligning function, can allow the air supporting piece tilt, and the air in it will emptying, does not form air film.And use the utlity model has the adjustment bolt of certain elasticity and aligning function, just can prevent the generation of above-mentioned phenomenon: front end holds out against head and threaded body Spielpassung, and be with the butterfly elastic washer, make the adjustment bolt have certain elasticity and aligning function, can prevent effectively that air supporting piece and granite guide rail from grinding away, and prevent " locking " phenomenon.
Claims (2)
1. the adjustment bolt of a three coordinate measuring machine connects air supporting piece and moving element, it is characterized in that adjusting bolt and comprises:
One front end holds out against head, holds out against the V-shaped depression of cephalic par, and the back segment diameter of axle is less than the leading portion diameter of axle;
One threaded body, central through bore is established the pad hole in the through hole, and front end holds out against a Spielpassung in the threaded body through hole;
One hexagon socket head cap screw, the pad hole of passing threaded body holds out against head thread with front end and is connected, and interior hexagonal end withstands on pad hole opposite side;
One butterfly elastic washer is enclosed within front end and holds out against on the back segment axle of head, places to hold out against between a leading portion axle and the threaded body.
