Description

Technical Field

[0001] The utility model relates to the technical field of three-coordinate measuring machines, in particular to an adjustable three-coordinate measuring machine. Background Art

[0002] Coordinate measuring machine is a metrological instrument used to measure and obtain dimensional data with high accuracy and good repeatability. Coordinate measuring machine is a high-precision and high-efficiency measuring equipment, widely used in mechanical engineering, automobile manufacturing, electronic industry, aerospace and other fields.

[0003] In the prior art, due to the excessive track resistance, after long-term use, the track of the three-dimensional coordinate measuring machine may experience sedimentation, accumulation and the like. In addition, the material accumulation caused by long-term use will make the track resistance too large, thereby affecting the movement. As a result, the position of the working platform of the three-dimensional coordinate measuring machine in the prior art is inconvenient to adjust. When the object to be measured is fixed on the working platform of the three-dimensional coordinate measuring machine using a fixture, if it is found that the object to be measured has some deviation, then it is necessary to remove the fixture again and re-fix it. When it is necessary to adjust a relatively large object to be measured, the operation is very troublesome, thereby affecting the measurement efficiency of the object to be measured.

[0004] Therefore, it is necessary to design an adjustable three-coordinate measuring machine. Utility Model Content

[0007] In one of the embodiments, a fixing rod and a limiting plate are further included. The fixing rod is symmetrically connected to the top surface of the workbench, and the limiting plate is slidably connected to the upper end of the fixing rod.

[0008] In one of the embodiments, a rubber pad is disposed at the bottom of the base.

[0009] In one of the embodiments, a fixing nut is further included, and the adjustment plate is fixed by the fixing nut.

[0020] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0021] Example: An adjustable three-dimensional coordinate measuring machine, please see Figures 1 to 5, including a base 1, a bracket 2, a measuring device 3, a sliding frame 4, a motor 5, a screw 6, a workbench 7, a fixing nut 8, an adjustment plate 9, a receiving block 10, a flexible clamp 11, a controller 12, a fixing rod 13 and a limit plate 14. A rubber pad is arranged at the bottom of the base 1 to increase the friction between the base 1 and the contact surface and play an anti-slip role. Brackets 2 are arranged on both sides of the rear of the base 1. The measuring device 3 is slidably installed in the middle of the bracket 2. The inner middle part of the base 1 is inlaid with a sliding frame 4. The rear side of the sliding frame 4 is installed with a motor 5. The output shaft of the motor 5 is connected to a screw 6 through a coupling. The screw 6 is rotatably connected to the middle of the sliding frame 4, and the screw 6 is connected by a thread There is a workbench 7, the surface of the workbench 7 is evenly spaced with threaded mounting holes, and four adjusting plates 9 are installed on the threaded mounting holes of the workbench 7 through four fixing nuts 8, the adjusting plates 9 are fixed by the fixing nuts 8, and are easy to disassemble and change positions, and receiving blocks 10 are installed on the adjusting plates 9, and flexible clamps 11 are installed on the tops of the receiving blocks 10, and controllers 12 are installed on the flexible clamps 11, and fixing rods 13 are symmetrically connected to the top of the workbench 7 front and back, and a limiting plate 14 is slidably connected to the upper end of the fixing rod 13, and damping materials are arranged at the sliding connection between the fixing rod and the limiting plate 14 to increase friction and prevent the limiting plate 14 from sliding at will.

[0022] When it is necessary to use a three-dimensional coordinate measuring machine to measure the size of the object to be measured, the three-dimensional coordinate measuring machine is first placed at a designated work location, and then the position of the flexible clamp 11 is adjusted according to the size of the object to be measured. By removing the fixing nut 8, the adjustment plate 9 is not fixed, and then the adjustment plate 9 is installed on the other threaded mounting holes of the workbench 7. After installation, the object to be measured can be placed on the four flexible clamps 11. After placement, the flexible clamp 11 is started by the controller 12 so that the flexible clamp 11 can clamp the object to be measured, and then the limit plate 14 is slid up and down to a suitable position according to the height of the object to be measured. After adjustment, the limit plate 14 can limit the surface of the object to be measured. Then, it can be observed whether the position of the object to be measured is located below the measuring device 3. If there is a deviation in the position, the motor 5 can drive the screw rod 6 to rotate, drive the workbench 7 and the object to be measured to move forward and backward in the slide frame 4 to adjust the position, so that the data measured by the object to be measured is not easy to deviate. This adjustment method relies on electric drive and does not require manual adjustment. There is no situation where the track resistance is large and it is difficult to adjust the position. When the position is adjusted, the measuring device 3 can be started to measure the object to be measured. The measuring device 3 in the coordinate measuring machine mainly measures the object to be measured through steps such as distance measurement position detection and data processing. When the measurement is completed, the controller 12 is used to control the flexible clamp 11 to close so that the flexible clamp 11 is not clamped, and the limit plate 14 is moved upward so that it does not limit the object to be measured. Finally, the measured object can be taken away.

[0023] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
