[0029] A support column 4 is fixedly connected to the bottom of the workbench 1, and a base plate 5 is fixedly connected to the bottom of the support column 4. A positioning hole 6 is provided on the top of the workbench 1, and snap-on quick-release mechanisms 7 are provided on both sides of the workbench 1. By providing the snap-on quick-release mechanisms 7, the process of installing and disassembling the calibration platform can be simplified, the required time can be reduced, and the efficiency can be improved. When the calibration platform needs to be moved or reconfigured according to different test requirements, the speed is faster, and the quick disassembly also facilitates the maintenance and servicing work.

[0030] The right-side snap-on quick-release mechanism 7 includes a fixed plate 71 fixedly connected to the right side of the workbench 1, an L-shaped plate 72 fixedly connected to the right side of the fixed plate 71, a sliding rod 73 slidably connected to the inner wall of the L-shaped plate 72, a snap block 74 fixedly connected to the left side of the sliding rod 73, a pull bar 75 fixedly connected to the right side of the sliding rod 73, and two spring bars 76 fixedly connected between the snap block 74 and the L-shaped plate 72.

[0031] There are four positioning holes 6, which are distributed in a rectangular array on the top of the workbench 1. The inner walls of the four positioning holes 6 are slidably connected with positioning rods 8. The tops of the four positioning rods 8 are fixedly connected with a mechanical calibration platform device body 9. The mechanical calibration platform device body 9 is electrically connected to an external power supply and controlled by an external program. The mechanical calibration platform device body 9 is a comprehensive calibration mechanical instrument, which is composed of multiple units such as a calibration system, a sensor system, and a measurement system. Buckle holes 10 are provided on both sides of the mechanical calibration platform device body 9.

[0032] The first half gear 37 and the second half gear 310 are both meshed with the gear plate 35 .

[0033] The two buckle quick-release mechanisms 7 have the same structure, and are symmetrically distributed on both sides of the workbench 1 .

[0034] Four support columns 4 are provided and distributed at the bottom edge of the workbench 1 in a rectangular array.

[0035] The two snap blocks 74 are both compatible with the adjacent snap holes 10. The inwardly facing parts of the two snap blocks 74 are designed with an angle to ensure that when the mechanical calibration platform device body 9 is downward, its bottom can push the two snap blocks 74 to move outward through the angle without getting stuck.

[0036] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0037] Working principle of the present invention: When installing the mechanical calibration platform device body 9, the mechanical calibration platform device body 9 is inserted into the four positioning holes 6 by vertically sliding the four positioning rods 8 to preliminarily position the mechanical calibration platform device body 9 on the workbench 1. When the mechanical calibration platform device body 9 falls downward, the buckle blocks 74 in the buckle quick release mechanism 7 on both sides are pushed to both sides, so that the two buckle blocks 74 overcome the elastic force of the spring bar 76, and slide outward on the inner wall of the L-shaped plate 72 through the sliding rod 73. When the mechanical calibration platform device body 9 completely falls on the workbench 1, when the two buckle holes 10 reach the position of the two buckle blocks 74, the elastic characteristics of the spring bars 76 on both sides cause the buckle blocks 74 to rebound and reset, and slide through the L-shaped plate 72, so that the two buckle blocks 74 are inserted into the adjacent buckle holes 10 toward the opposite side, thereby locking the mechanical calibration platform device body 9 and firmly installing it on the workbench 1. When disassembly is required, it is only necessary to hold the two pull bars 75, and pull the two buckle blocks 74 toward the outside through the two sliding rods 73, so that the two buckle blocks 74 are no longer located in the buckle holes 10, and then the mechanical calibration platform device body 9 is pulled out and disassembled upward. Next, the connecting strip 343 in the quick-release wiper strip assembly 34 is slid and inserted between the outer surfaces of the two insertion rods 342, and then the screw rod 344 is aligned with the inner wall of the mounting strip 341 and the connecting strip 343, and the cover 345 is turned so that the screw rod 344 fixes the mounting strip 341 and the connecting strip 343 together, thereby realizing the installation of the wiper strip 346. Then the motor 32 is started, and it drives the first pulley 36 and the first half gear 37 to rotate through the output shaft. While the first pulley 36 rotates, the second pulley 39 is driven through the transmission chain 311, so that the second pulley 39 rotates synchronously on the top of the fixed seat 33 through the rotating shaft 38, and the second half gear 310 on the rotating shaft 38 also rotates synchronously. Since the first half gear 37 and the second half gear 310 have teeth on only half of their sides, they will alternately mesh with the tooth plate 35 when they continue to rotate, thereby driving the tooth plate 35 and the sliding rod 31 to move back and forth between the inner walls of the protection groove 2. This movement causes the wiping strip 346 in the quick-release wiping strip assembly 34 on the front of the sliding rod 31 to wipe the workpiece contact top surface of the mechanical calibration platform device body 9 back and forth. After the wiping is completed, the mechanical calibration platform device body 9 is finally put into use.
