[0002] As a precision measuring device, the measurement accuracy of the three-dimensional coordinate measuring machine is crucial to product quality control and the research and development process.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] Example 1

[0017] like Figure 1 , Figure 2 As shown, a specific embodiment of a three-coordinate measuring machine base shock absorbing device described in the utility model comprises: a support seat 1 arranged at the bottom of the three-coordinate, a support plate 2 is fixedly mounted on the support seat 1, a shock absorbing structure is mounted on the support plate 2, the shock absorbing structure comprises a shock absorbing bottom plate 3, a shock absorbing top plate 6, a shock absorbing pad 5 and a damping shock absorber 4, the shock absorbing bottom plate 3 is fixedly connected to the support plate 2 by a first fixing bolt 8, the lower end of the shock absorbing pad 5 is mounted on the shock absorbing bottom plate 3 by a third fixing bolt 11, the upper end of the shock absorbing pad 5 is fixedly connected to the shock absorbing top plate 6 by a third fixing bolt 11, the shock absorbing top plate 6 is used to support the three-coordinate measuring machine, and the damping shock absorber 4 is vertically arranged on one side of the shock absorbing pad 5, and plays a shock absorbing role together with the shock absorbing pad 5.

[0018] The damping shock absorber 4 is fixedly installed with an assembly plate 7 at both upper and lower ends. The assembly plate 7 is installed on the shock absorbing base plate 3 and the shock absorbing top plate 6 through the second fixing bolts 10. It can be easily installed on the shock absorbing base plate 3 and the shock absorbing top plate 6 through the second fixing bolts 10, and is convenient for disassembly and replacement.

[0019] The damping shock absorber 4 includes an outer cylinder 12 for bottom support and an inner cylinder 13 for shock absorption which is inserted into the outer cylinder 12. The side walls and bottoms of the outer cylinder 12 and the inner cylinder 13 are filled with solid oil for shock absorption. The viscous resistance of the solid oil is used to absorb and transform the vibration energy.

[0020] The shock-absorbing base plate 3 is threadedly mounted with leveling bolts 9, which are arranged in a triangle and are set in three. The bottom of the leveling bolts 9 abuts against the upper surface of the support plate 2. The leveling bolts 9 are used for horizontal adjustment of the base. The base can be adjusted horizontally according to actual needs and is suitable for different on-site environments.

[0021] The shock-absorbing pad 5 is made of rubber material and is arranged in a vertically stacked double-layer structure to improve the shock-absorbing effect.

[0022] The working principle of the utility model is as follows: when the three-dimensional coordinate measuring machine is subjected to external vibration, the shock-absorbing pad 5 first exerts the elasticity of its rubber material to preliminarily absorb and disperse the vibration energy. At the same time, the inner cylinder 13 in the damping shock absorber 4 moves relatively inside the outer cylinder 12, and the viscous resistance of the solid oil is used to absorb and transform the vibration energy, thereby further reducing the influence of the vibration on the measuring machine. This double shock-absorbing structure can significantly reduce the influence of the vibration on the measuring machine and improve the measurement accuracy.

[0023] The components in this article are all universal standard parts or components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

[0024] Although the specific embodiments of the present invention are described in detail above, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the field without departing from the purpose of the present invention, and modifications or deformations without creative labor are still within the scope of protection of the present invention.
