Description

Technical Field

[0001] This utility model relates to the technical field of coordinate measuring machine components, specifically a high-precision shock-absorbing base component for a coordinate measuring machine. Background Technology

[0002] A coordinate measuring machine (CMM) is a high-precision measuring device that detects the size, shape, and position of an object using a three-dimensional coordinate system. It acquires data through probe contact or optical scanning and is widely used in industrial manufacturing and quality control. The accuracy and performance of a CMM are closely related to the environment, with vibration being one of the main factors affecting performance. Currently, to ensure stable operation of a CMM, vibration-damping base components are typically used for vibration reduction.

[0003] Commercially available shock-absorbing base components typically lack sufficient shock absorption, which can negatively impact the normal operation of coordinate measuring machines (CMMs) and reduce their measurement accuracy. Therefore, we propose a high-precision shock-absorbing base component for CMMs. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision shock-absorbing base component for a coordinate measuring machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision vibration damping base component for a coordinate measuring machine, comprising a base support frame and a vibration damping assembly. The base support frame is an integrated structure made of cast iron alloy material. The vibration damping assembly is disposed on the upper side of the base support frame and includes an air-bearing vibration damper, a polyurethane buffer pad, a marble vibration damping platform, a fixed base cylinder, a buffer spring, and a movable inner rod. The air-bearing vibration dampers are disposed on both sides of the upper surface of the base support frame, and four sets of air-bearing vibration dampers are provided. The upper surface of the air-bearing vibration damper is connected to the polyurethane buffer pad, and the upper side of the polyurethane buffer pad is provided with a marble vibration damping platform. The lower surface of the marble vibration damping platform is tightly connected to the upper surface of the polyurethane buffer pad.

[0006] Furthermore, the upper surface of the base support frame is equipped with fixed bottom cylinders at both the front and rear ends, and the lower surface inside the fixed bottom cylinders is provided with buffer springs.

[0007] Furthermore, a movable inner rod is provided on the upper side of the buffer spring, and the movable inner rod is slidably connected to the inner side of the fixed bottom cylinder.

[0008] Furthermore, the lower surface of the marble shock-absorbing platform is connected to the top of the movable inner rod, and the marble shock-absorbing platform is an integrated structure.

[0009] Furthermore, the lower side of the base support frame is provided with an adjustment component for adjusting the height of the base, and the adjustment component includes a threaded movable support rod, an auxiliary handwheel, a support base, a fixed base plate and a fixed frame, and the threaded movable support rod is threadedly connected to the lower sides of both ends of the base support frame.

[0010] Furthermore, an auxiliary handwheel is installed on the top of the threaded movable support rod, and a support base is provided at the bottom of the threaded movable support rod. A fixed base plate is installed at the bottom of the support base, and a fixing frame is provided on the upper surface of the fixed base plate.

[0011] Furthermore, the adjustment assembly also includes a servo motor, a threaded screw, and a support cylinder.

[0013] This utility model provides a high-precision shock-absorbing base component for a coordinate measuring machine, which has the following features:

[0014] Beneficial effects:

[0015] 1. This utility model incorporates a shock-absorbing component, which includes an air-floating shock absorber, a polyurethane buffer pad, a marble shock-absorbing platform, a fixed base cylinder, a buffer spring, and a movable inner rod. In use, the air-floating shock absorber utilizes the compressibility of gas to absorb vibration energy and dissipates vibration through the viscous damping effect of air film flow, achieving near-zero friction and highly efficient vibration isolation. A polyurethane buffer pad is installed between the air-floating shock absorber and the marble shock-absorbing platform to absorb high-frequency residual vibration. The marble shock-absorbing platform, with its high density and rigid structure, absorbs low-frequency vibration energy, further enhancing the overall shock absorption effect. When vibration occurs, the movable inner rod slides along the inner side of the fixed base cylinder, compressing the buffer spring and achieving a buffering and shock-absorbing effect. Therefore, this device strengthens the overall shock absorption effect of the base, reduces the impact of vibration on the coordinate measuring machine (CMM), and improves the measurement accuracy of the CMM.

[0016] 2. This utility model incorporates an adjustment component, which includes a threaded movable support rod, an auxiliary handwheel, a support base, a fixed base plate, and a fixed frame. The adjustment component also includes a servo motor, a threaded screw, and a support cylinder. In use, the servo motor is activated, causing the threaded screw to rotate. The threaded screw then moves the support cylinder up and down along its surface, which in turn moves the base support frame up and down. Once the desired height is reached, the auxiliary handwheel is used to rotate the threaded movable support rod, causing it to move downwards along both ends of the base support frame until the lower surface of the support base is tightly connected to the upper surface of the fixed base plate. This provides stable support for the base support frame, allowing for overall height adjustment and stable support, adaptable to different usage positions. Attached Figure Description

The upper surface of the air-bearing vibration damper 201 is connected to a polyurethane... A buffer pad 202 is provided, and a marble shock-absorbing platform 203 is provided on the upper side of the polyurethane buffer pad 202. The lower surface of the marble shock-absorbing platform 203 is tightly connected to the upper surface of the polyurethane buffer pad 202. Fixed bottom cylinders 204 are installed at both the front and rear ends of the upper surface of the base support frame 1. A buffer spring 205 is provided on the lower surface inside the fixed bottom cylinder 204. A movable inner rod 206 is provided on the upper side of the buffer spring 205. The movable inner rod 206 is slidably connected to the inner side of the fixed bottom cylinder 204. The lower surface of the marble shock-absorbing platform 203 is connected to the top of the movable inner rod 206. The marble shock-absorbing platform 203 is an integrated structure.

[0024] The specific operation is as follows: When in use, the air flotation shock absorber 201 absorbs vibration energy by utilizing the compressibility of gas, and dissipates vibration through the viscous damping effect of air film flow, achieving high-efficiency vibration isolation with near-zero friction. A polyurethane buffer pad 202 is installed between the air flotation shock absorber 201 and the marble vibration damping platform 203, which can absorb high-frequency residual vibration. The marble vibration damping platform 203 absorbs low-frequency vibration energy through its high-density and rigid structure, which can further improve the overall vibration damping effect. When vibration occurs, the movable inner rod 206 slides along the inner side of the fixed bottom cylinder 204, compressing the buffer spring 205, and achieving the buffering and vibration damping effect through the buffer spring 205.

[0025] Please refer to Figure 1 and Figure 4The base support frame 1 has an adjustment assembly 3 for adjusting the height of the base. The adjustment assembly 3 includes a threaded movable support rod 301, an auxiliary handwheel 302, a support base 303, a fixed base plate 304, and a fixing frame 305. The threaded movable support rod 301 is threaded to the lower sides of both ends of the base support frame 1. The auxiliary handwheel 302 is installed on the top of the threaded movable support rod 301, and the support base 303 is provided at the bottom of the threaded movable support rod 301. The fixed base plate 304 is installed at the bottom of the support base 303, and a fixing frame 305 is provided on the upper surface of the fixed base plate 304. The fixed frame 305 and the adjustment assembly 3 also include a servo motor 306, a threaded screw 307 and a support cylinder 308. The servo motor 306 is provided inside the fixed frame 305. The output end of the servo motor 306 is connected to the threaded screw 307 through a coupling. The support cylinder 308 is threadedly connected to the outer surface of the threaded screw 307. The top of the support cylinder 308 is tightly connected to the upper and lower surfaces of the base support frame 1. The lower surface of the fixed base plate 304 is provided with an anti-slip rubber pad 4. The upper surface of the anti-slip rubber pad 4 is tightly connected to the lower surface of the fixed base plate 304 through an adhesive.

[0026] The specific operation is as follows: When in use, start the servo motor 306, which drives the threaded screw 307 to rotate. The threaded screw 307 drives the support cylinder 308 to move up and down along the surface of the threaded screw 307. The support cylinder 308 drives the base support frame 1 to move up and down. After moving to a suitable height, rotate the threaded movable support rod 301 by the auxiliary handwheel 302, so that the threaded movable support rod 301 moves down along the lower sides of both ends of the base support frame 1 until the threaded movable support rod 301 drives the support seat 303 to move down until its lower surface is tightly connected to the upper surface of the fixed base plate 304, thus achieving stable support for the base support frame 1. The bottom of the fixed base plate 304 is equipped with an anti-slip rubber pad 4, which can reduce the vibration energy transmitted by rigid contact.

[0027] In summary, as Figures 1 to 4As shown, this coordinate measuring machine uses a high-precision shock-absorbing base component. In use, firstly, the servo motor 306 is started, causing the servo motor 306 to drive the threaded screw 307 to rotate. The threaded screw 307 then drives the support cylinder 308 to move up and down along the surface of the threaded screw 307. The support cylinder 308 then drives the base support frame 1 to move up and down. After moving to a suitable height, the auxiliary handwheel 302 is used to rotate the threaded movable support rod 301, causing the threaded movable support rod 301 to move downwards along the lower sides of both ends of the base support frame 1 until the threaded movable support rod 301 drives the support seat 303 downwards until its lower surface is tightly connected to the upper surface of the fixed base plate 304, achieving stable support for the base support frame 1. (Air-floating shock absorber) 201 utilizes the compressibility of gas to absorb vibration energy, and dissipates vibration through the viscous damping effect of air film flow, achieving near-zero frictional high-efficiency vibration isolation. A polyurethane buffer pad 202 is installed between the air-floating shock absorber 201 and the marble shock absorption platform 203 to absorb high-frequency residual vibration. The marble shock absorption platform 203 absorbs low-frequency vibration energy through its high-density and rigid structure, which can further improve the overall shock absorption effect. When vibration occurs, the movable inner rod 206 slides along the inner side of the fixed base cylinder 204, compressing the buffer spring 205, and achieving the buffering and shock absorption effect through the buffer spring 205. At the same time, an anti-slip rubber pad 4 is added to the bottom of the fixed base plate 304, which can reduce the vibration energy transmitted by rigid contact.
