Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to fixed cantilever measuring machine cantilever structure technology BACKGROUND
[0002] In the prior art, the fixed cantilever measuring machine generally uses reinforced cantilever structure stiffness to overcome the deflection deformation of the cantilever beam caused by the cantilever load.
[0003] The problem of the prior art is that the reinforced cantilever structure stiffness cannot completely overcome the deflection deformation of the cantilever beam caused by the downward bending of the cantilever load, and it is difficult for large-size fixed cantilever measuring machines to achieve high-precision index requirements. SUMMARY
[0004] The present application provides a fixed cantilever measuring machine with a multi-adjustment node strain beam structure, which can solve the problem of large-size fixed cantilever measuring machines achieving high-precision index requirements.
[0005] To achieve the above purpose, the technical scheme adopted by the present application is: a fixed cantilever measuring machine with a multi-adjustment node strain beam structure, comprising a support column, a guide rail platform, a strain beam integrated base, a cantilever beam, a y-axis slide seat and a z-axis assembly, the guide rail platform is installed on the support column, the strain beam integrated base adopts a design structure in which the base and the strain beam are integrated, the strain beam is installed with ball head jacks at equal intervals, and the extension height is adjusted by adjusting bolts.
[0006] The base end of the strain beam integrated base is installed on the linear guide rail of the guide rail platform, the strain beam of the strain beam integrated base is suspended outward, one end of the cantilever beam is installed on the base of the strain beam integrated base, and the suspended end is supported by the ball head jacks installed on the strain beam of the strain beam integrated base, the y-axis slide seat is installed on the linear guide rail of the cantilever beam, and the z-axis assembly is installed on the y-axis slide seat, when the y-axis slide seat moves along the cantilever beam, the dead weight of the cantilever beam and the load of the y-axis slide seat cause the cantilever beam to bend downward and produce deflection deformation, the adjusting bolts of the ball head jacks installed at different positions of the strain beam of the strain beam integrated base are adjusted, the supporting force of the ball head jacks causes the cantilever beam to produce pre-deformation upward, since the directions are opposite, when the pre-deformation curve value of the cantilever beam is the same as the deflection deformation curve value, the deflection deformation of the cantilever beam is cancelled out.
[0007] Due to the application of the above technical solution, the beneficial effects of this invention compared with the prior art are as follows: The fixed cantilever measuring machine with a multi-adjustable strain beam structure achieves the measurement of the cantilever beam direction (Y-axis) by moving the Z-axis guide slide on the linear guide rail of the cantilever beam. Since the cantilever beam is supported by a row of equally spaced ball head rods installed on the strain beam of the integrated strain beam base, the cantilever beam generates a pre-deformation upward by adjusting the adjusting bolts of the ball head rods at different positions. When the pre-deformation curve value of the cantilever beam is the same as the deflection deformation curve value, the deflection deformation of the cantilever beam is canceled out, which can achieve the high precision index requirements of large-size fixed cantilever measuring machines.

[0012] See appendix Figure 1 Appendix Figure 2 A fixed cantilever measuring machine with a multi-adjustable strain beam structure includes a support column, a guide rail platform, an integrated strain beam base, a cantilever beam, a Y-axis slide, and a Z-axis assembly. The guide rail platform is mounted on the support column. The integrated strain beam base adopts a design where the base and strain beam are integrated. Ball-head push rods are installed at equal intervals on the strain beam, and the extension height is adjusted by adjusting bolts. The base end of the integrated strain beam base is mounted on the linear guide rail of the guide rail platform. The strain beam of the integrated strain beam base extends outward, and one end of the cantilever beam is mounted on the base of the integrated strain beam base, while the extended end is mounted on the strain beam base. The ball-head push rods on the strain beam of the integrated beam base are supported. The y-axis slide is mounted on the linear guide rail of the cantilever beam, and the z-axis assembly is mounted on the y-axis slide. When the y-axis slide moves along the cantilever beam, the self-weight of the cantilever beam and the load of the y-axis slide cause the cantilever beam to bend downward and produce deflection deformation. By adjusting the adjusting bolts of the ball-head push rods at different positions on the strain beam of the integrated strain beam base, the supporting force of the ball-head push rods causes the cantilever beam to produce pre-deformation upward. Since the directions are opposite, when the pre-deformation curve value of the cantilever beam is the same as the deflection deformation curve value, the deflection deformation of the cantilever beam is canceled out.
