Description

Technical Field

[0001] This utility model relates to the field of coordinate measuring technology, and in particular to an auxiliary device for coordinate measuring. Background Technology

[0002] Three-dimensional coordinate measurement is a key technology used for product inspection and quality control in modern industry. It is mainly realized through a coordinate measuring machine (CMM). The CMM uses three mutually perpendicular motion axes (X, Y, Z) to establish a rectangular coordinate system. By having the probe contact the surface of the workpiece, the system obtains the precise coordinates of the center point of the measuring ball in real time, thereby calculating the geometric dimensions, shape, and positional tolerances of the workpiece.

[0003] In actual measurement operations, the operator needs to operate both the coordinate measuring machine's control cabinet (or computer) and the measuring arm simultaneously. Traditionally, the control computer is placed on a standard workbench or trolley, while the measuring arm is fixed to the machine body. This method presents several inconveniences:

[0004] 1. Poor flexibility: The equipment layout is fixed, making it difficult to flexibly adjust the relative positions of the computer and measuring arm according to the measurement task and site conditions. This is especially inefficient when measuring large workpieces or when moving between different workstations.

[0005] 2. Poor ergonomics: The height and angle of the computer screen and measuring arm are not adjustable, which can easily cause operator fatigue during long-term work, affecting measurement accuracy and physical health.

[0006] Therefore, there is an urgent need for a dedicated auxiliary device that can integrate measurement and control equipment with a measuring arm, and can flexibly adjust its position and posture to adapt to multiple scenarios, improve measurement efficiency and operational comfort.

[0025] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0026] Reference Figure 1 , Figure 1This is a perspective view of the present invention. The present invention provides an auxiliary device for coordinate measuring machine (CMM) measurement, comprising a base 1, a first platform 2, a second platform 3, a lifting column 4, a storage platform 5, a measuring arm placement platform 6, and an adjustment mechanism 7. The base 1 is a movable frame structure, and the lower part of the base 1 is provided with multiple casters 11 for easy movement. The base 1 is provided with a fixing device 12, and the upper part of the fixing device 12 is provided with a fixing device knob 13. By operating the fixing device knob 13 and the fixing device 12, the position of the base 1 can be fixed on the slide or a corresponding position, so that the auxiliary device can move flexibly and can be stably stopped during operation. The first platform 2 is fixedly installed above the base 1, and the second platform 3 is detachably connected to the first platform 2. If the overall height of the auxiliary device is inconvenient for measurement, the base 1 can be separated from the upper device for better and more flexible measurement. The height-adjustable lifting column 4 is installed above the second platform 3. The lifting column 4 is connected to a storage platform 5 and a measuring arm placement platform 6. The storage platform 5 is used to place the measuring equipment and computer, and the measuring arm placement platform 6 is used to magnetically place the coordinate measuring equipment. The measuring arm placement platform 6 is equipped with a magnetic component (not shown) to prevent the coordinate measuring equipment from accidentally moving or falling.

[0027] In a preferred embodiment, the platform 5 is connected to the lifting column 4 via an adjustment mechanism 7. The adjustment mechanism 7 can rotate around the lifting column 4 and can be fixed in place by a self-locking mechanism or an additional locking device. The adjustment mechanism 7 is provided with an angle adjustment knob 71 for fixing and adjusting the tilt angle of the platform 5, which can change the pitch angle of the platform 5, making it convenient for the operator to observe the control computer screen from the best viewing angle. The lifting column 4 includes a base column 41, a lifting column 42 connected to the base column 41, and a height adjustment knob 43 provided on the base column 41 for fixing and adjusting the lifting column 42. By rotating the height adjustment knob 43, the lifting column 42 can be loosened or locked, thereby driving the platform 5 above and the measuring arm placement platform 6 to rise and fall together, realizing height adjustment.

[0028] The following will refer to Figure 1 The working principle of this utility model will be explained.

[0029] When in use, push the device near the workpiece to be measured, lock the universal wheel 11 brake, and the operator places the control computer of the coordinate measuring machine on the platform 5, places the measuring arm on the measuring arm platform 6 and fixes it magnetically. According to the work scene and the operator's own height, adjust the height of the device, the angle and orientation of the platform, and then start efficient and comfortable measurement work. If the overall height of the device is not suitable for the work scene, the lower base 1 can be separated from the upper device, then adjusted, and then the measurement work can be carried out.

[0030] This utility model discloses an auxiliary device for coordinate measuring machine (CMM) measurement, integrating multi-dimensional adjustment functions for height, angle, and rotation. It is multi-functional and more flexible, eliminating the need for operators to move between a fixed control console and the measuring machine. Operators can push the device along the workpiece, achieving "movement, measurement, and observation simultaneously," making it particularly suitable for on-site measurement of large workpieces and significantly improving measurement efficiency. The universal caster design allows for easy movement and positioning on various surfaces such as the ground and sliding tables. The modular table design and multi-dimensional adjustment functions enable it to adapt to different working environments, workpiece types, and operator habits. The adjustable height and angle allow operators to operate in the most comfortable and healthiest posture, demonstrating excellent ergonomic design, reducing work fatigue, and indirectly ensuring the long-term stability of measurement data. The structure is rationally designed, with simple and effective adjustment mechanisms, intuitive and convenient operation, low manufacturing cost, and easy promotion and use.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
