[0041] The utility model is further illustrated by the following examples, but the utility model is not limited in the scope of the examples.

[0042] As Figures 1-7 shown, the coordinate measuring machine 1 measurement detection auxiliary tool, including setting on the coordinate measuring machine 1 gantry 102;Still include: turnover mechanism 4, the number of turnover mechanism 4 is two, and two turnover mechanisms 4 are symmetrically installed to the both sides of gantry 102;Turnover plate 2, the top surface of turnover plate 2 is used to place the workpiece to be measured;The number of two turnover plates 2 is two, and two turnover plates 2 are arranged below turnover mechanism 4;Drive mechanism 3, drive mechanism 3 is connected with two turnover plates 2;Blowing mechanism 5, blowing mechanism 5 is arranged below turnover plate 2, and blowing mechanism 5 is connected with spray head 8 through pipe fitting.

[0043] The coordinate measuring machine 1 includes a machine table 101, the gantry 102 is installed to the top of the machine table 101, the top surface of the machine table 101 is provided with a through slot 1011, and two turnover plates 2 are arranged in the through slot 1011;The upper portion of the gantry 102 is provided with a lifting telescopic rod 103, and the bottom end of the lifting telescopic rod 103 is provided with a probe 104.

[0044] As Figure 4As shown, the drive mechanism 3 includes a protective shell 301, which is fixedly connected to the side wall of the machine base 101. A first motor 302 is fixedly connected to the outer wall of one end of the protective shell 301. A first rotating shaft 303 is rotatably installed inside the protective shell 301. The end of the first rotating shaft 303 is fixedly connected to the output shaft of the first motor 302. Two sets of symmetrically arranged transmission parts are provided on the first rotating shaft 303. The two sets of transmission parts are connected to two flipping carrier plates 2.

[0045] The transmission unit includes a first bevel gear 304 and a second bevel gear 305, which are meshed together. The first bevel gear 304 is fixedly sleeved on the first rotating shaft 303, and the second bevel gear 305 is fixedly connected to a second rotating shaft 306. The second rotating shaft 306 is rotatably connected to the protective shell 301 and is fixedly connected to the flipping carrier plate 2.

[0046] like Figures 2-3 As shown, the flipping mechanism 4 includes a lateral telescopic rod 401; the lateral telescopic rod 401 is fixedly connected to the outer wall of the gantry frame 102, and a movable frame 403 is fixedly connected to the output end of the lateral telescopic rod 401. A flipping part is installed on the movable frame 403, and a clamping plate 402 is connected to the flipping part.

[0047] The flipping part includes a second motor 404; the second motor 404 is fixedly installed on the movable frame 403, the output shaft end of the second motor 404 is fixedly connected to a first pulley 405, a second pulley 406 is rotatably installed on the movable frame 403, a transmission belt 407 is wound between the first pulley 405 and the second pulley 406, and the second pulley 406 is fixedly connected to the side wall of the clamping plate 402.

[0048] When the workpiece is flipped to change its top and bottom sides, the lateral telescopic rod 401 extends, causing the clamping plates 402 of the two flipping mechanisms 4 to press against both sides of the workpiece. Then, the drive mechanism 3 drives the flipping carrier plate 2 to flip downwards, creating space below the workpiece and preventing obstruction to subsequent flipping. Specifically, the second motor 404 drives the first pulley 405 to rotate, which is transmitted through the transmission belt 407, causing the second pulley 406 to drive the clamping plates 402 and the clamped workpiece to flip together. After flipping, the drive mechanism 3 resets the flipping carrier plate 2 to a horizontal state. Figure 1 As shown, the lateral telescopic rod 401 then retracts, causing the clamping plate 402 to separate from the workpiece.

[0049] In the above, the drive mechanism 3 drives the flipping carrier plate 2 to flip down by 90°. The drive mechanism 3 operates as follows: the first motor 302 drives the first rotating shaft 303 to rotate, and the two first bevel gears 304 on the first rotating shaft 303 rotate together. Through the meshing of the first bevel gears 304 and the second bevel gears 305, the two second rotating shafts 306 drive the two flipping carrier plates 2 to rotate.

[0050] Both the first motor 302 and the second motor 404 are servo motors.

[0051] Both the lifting telescopic rod 103 and the lateral telescopic rod 401 use pneumatic or hydraulic cylinders.

[0052] like Figure 1 , Figure 5 As shown in Figure 6, there are multiple blower mechanisms 5. Each blower mechanism 5 includes a fixed frame 501 fixed to the machine base 101. An air cylinder 502 is fixedly connected to the fixed frame 501. A piston 506 is connected inside the air cylinder 502. A movable rod 507 is fixedly connected to the top of the piston 506. The movable rod 507 passes through a through hole opened at the top of the air cylinder 502, and a push plate 508 is fixedly connected to the top of the movable rod 507. An inlet one-way valve 503 and an outlet one-way valve 504 are provided at the bottom of the air cylinder 502. A filter is provided on the inlet one-way valve 503.

[0053] A return spring 505 is provided inside the air cylinder 502, and the return spring 505 is located at the bottom of the piston 506.

[0054] The fitting includes a connecting pipe 6, which is connected to an air outlet check valve 504. The connecting pipe 6 is connected to a spiral hose 7, which is connected to a nozzle 8.

[0055] A mounting bracket 9 is fixedly connected to the side wall of the machine base 101, and the nozzle 8 is engaged with the mounting bracket 9.

[0056] Before the rotating carrier plate 2 is rotated downwards, the operator manually removes the nozzle 8 and positions it towards the probe 104. During the subsequent rotation of the carrier plate 2 downwards, the push plate 508 is pushed downwards. The push plate 508 drives the piston 506 via the movable rod 507 to compress the gas in the air cylinder 502, while simultaneously compressing the return spring 505. The gas passes through the outlet check valve 504, connecting pipe 6, and hose 7 before being sprayed out from the nozzle 8 to clean the probe 104. Through this design, the probe 104 is cleaned once each time a workpiece is rotated and adjusted, ensuring cleanliness.

[0057] After cleaning, the nozzle 8 is secured to the holder 9, and the carrier plate 2 is flipped back to horizontal. The piston 506, the moving rod 507, and the push plate 508 are reset by the elastic force of the reset spring 505. The air cylinder 502 is then introduced through the air inlet check valve 503, so that the air cylinder 502 contains gas for the next cleaning. At the same time, the incoming air is filtered through the filter to ensure cleanliness.

[0058] The filter can be made of non-woven fabric filter material, which is adhered to the air inlet check valve 503.

[0059] In practical implementation, a lifting structure, such as a cylinder or hydraulic cylinder, is set at the installation position of the gantry frame 102 at the top of the platform to drive the gantry frame 102 and the tilting mechanism 4 on the gantry frame 102 to adjust the vertical position.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
