Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
With reference to Fig. 1, the one circle grid chi mount pad structure described in the present embodiment comprises: circle grid chi 1, mount pad 2 and central shaft 3, described mount pad 2 is arranged between described round grid chi 1 and central shaft 3, and coaxially setting between three.
The centre of described round grid chi 1 offers the first installing hole 10 of a truncated cone-shaped along its axis direction, described the first installing hole 10 runs through an end face on round grid chi 1.
Described mount pad 2 comprises the first construction section 21, the second construction section 22.The shape size of described the first construction section 21 is identical with described the first installing hole 10.These the first construction section 21 clampings are to described the first installing hole 10.Described the first construction section 21 coaxially arranges with circle grid chi 1.Described the first construction section 21 covers on an end face of the second construction section 22.The diameter of this first construction section 21 is pointed to by the second construction section 22 in the direction of the first construction section 21 and successively decreases successively.Described the first construction section 21 and the second construction section 22 can be formed in one.
On the end face of described the second construction section 22 away from the first construction section 21, offer the second installing hole 23.This second installing hole 23 is layer truncated cone-shaped also.The second installing hole 23 run through an end face of described the second construction section 22.Preferably, described the second construction section 22 can be cylindrical.The diameter of described the second construction section 22 can be (0.8 ~ 0.9) with the ratio of the maximum gauge of described the first construction section 21: 1.Described the second construction section 22 and the first construction section 21 coaxially arrange.Because the diameter of the second construction section 22 is greater than the maximum gauge of described the first construction section 21, so relative the first construction section 21 of the surrounding of the second construction section 22 protrudes, what form an annular supports wall 24.The described wall 24 that supports offsets with the periphery wall 11 of described the first installing hole 10.
The end of described central shaft 3 one end comprises a joint end 31.Described joint end 31 is connected in described the second installing hole 23, and by screw, described joint end 31 is fixed on described mount pad 2.The shape of this joint end 31 is identical with described the second installing hole 23.
Preferably, the maximum gauge of described the second installing hole 23 is (0.5 ~ 0.8) with the ratio of the maximum gauge of the first installing hole 10: 1.
Preferably, the maximum gauge of described the first installing hole 10 with the ratio of minimum diameter is: 1:(0.92 ~ 0.98).So proportionate relationship, when the first construction section 21 clamping to the first installing holes 10 are when interior, can ensure the stability of the first construction section 21 and circle grid chi 1, utilize the Self-centering Action of the conical surface simultaneously, can also effectively improve the axiality of the first construction section 21 and circle grid chi 1.The maximum gauge of described the second installing hole 23 with the ratio of minimum diameter is also: 1:(0.92 ~ 0.98).So proportionate relationship, when joint end 31 clamping to the second installing holes 23 of central shaft 3 are when interior, can ensure central shaft 3 and the second construction section 22 between stability, utilize the Self-centering Action of the conical surface simultaneously, can also effectively improve the axiality of central shaft 3 and the second construction section 22.
Described round grid chi 1 can be circle grating or circle magnetic grid.
Operation principle of the present utility model:
In the time wanting control centre's axle 3 accurate calibration, often need to use round grid chi 1, but because circle grid chi 1 often differs greatly with central shaft 3 appearance and size between the two, at this moment just need a mount pad 2 to play therein connection function, improve axiality, and make its use more convenient.
In addition, owing to requiring very high-axiality (require several μ even higher) guarantee to justify the normal work of grid chi 1 between circle grid chi 1 and central shaft 3.Therefore exist, when assembling, first mount pad 2 is coordinated to assembling with central shaft 3 as shown in Figure 1, utilize the Self-centering Action of the conical surface, auxiliary amesdial is beaten mount pad 2 radially or the beating of end face, slowly even lock-screw simultaneously, so circulation, ensures the axiality requirement that mount pad 2 and central shaft 3 are required while finally locking; Utilize same method to ensure the axiality requirement of mount pad 2 and circle grid chi 1.Like this, by the conical surface and the amesdial of mount pad 2 first construction sections 21, ensure well the axiality requirement of central shaft 3 with mount pad 2, the axiality requirement of mount pad 2 and circle grid chi 1, thereby the axiality requirement of guarantee central shaft 3 and circle grid chi 1.
Round grid chi mount pad structure of the present utility model is by being all processed as the conical surface by the inner surface mating surface of the appearance of the first construction section 21 of mount pad 2 and the second installing hole 23, in the time of assembling, utilize the Self-centering Action of the conical surface, in the second best in quality situation of cone face process, often evenly between latter two mating parts of lock-screw, just there is high axiality, at this moment auxiliary amesdial assembling is easy to the axiality requirement that reaches required, and reliability is high.Reduce the assembling and setting time, boost productivity.And round grid chi mount pad structure of the present utility model can be by ensureing the convenient installation of placing amesdial of axiality of beating to control two parts of mount pad 2 or circle grid chi 1 end face.Therefore round grid chi mount pad structure of the present utility model is easy to use, and it is simple and practical.
To one skilled in the art, can be according to technical scheme described above and design, make other various corresponding changes and deformation, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
