[0002] A coordinate measuring machine (CMM) is a high-precision measuring device that obtains the geometric shape and size information of an object by probing points on its surface. CMMs can achieve very high measurement accuracy, typically down to the micrometer level or even higher. This allows them to meet the measurement needs of most precision manufacturing industries. They can measure various geometric elements, including points, lines, surfaces, cylinders, cones, spheres, etc., and can evaluate various geometric tolerances, providing comprehensive geometric shape and size information. Therefore, they are used in various fields.

[0003] In existing technologies, the relative positions of the non-sliding components of a coordinate measuring machine are locked, causing displacement of the detection equipment and making it difficult to guarantee detection accuracy. Utility Model Content

The upper end of the locking mechanism is connected to the transverse sliding mechanism, the lower end of the locking mechanism is connected to the measuring platform, and the locking mechanism is connected to the horizontal sliding mechanism via a connecting plate.

[0006] Preferably, the horizontal sliding mechanism includes an active support and a driven support, both of which are mounted on the measuring platform, and a fixed trajectory walking mechanism is provided between the active support and the measuring platform.

[0009] Preferably, the locking mechanism includes a lower locking plate and an upper locking plate. The lower locking plate has a circular mounting hole 1 at both its upper and lower ends.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The locking device for a coordinate measuring machine includes components such as a lower locking plate, an upper locking plate, an L-shaped fixing plate, and a connecting plate. During operation, the lower and upper locking plates work together to connect and lock the horizontal sliding mechanism to the measuring table. The L-shaped fixing plate connects to the outer casing of the horizontal sliding mechanism, further improving connection stability. The connecting plate connects the horizontal sliding mechanism to the measuring table, thus locking the horizontal sliding position and preventing displacement of the measuring equipment during operation, thereby ensuring measurement accuracy.

[0015] 2. The locking device for the coordinate measuring machine uses components such as Reinforcing Plate 2 and Reinforcing Plate 1. During operation, Reinforcing Plate 1 reinforces the lower locking plate, thereby improving the stability of the lower locking plate during operation. Reinforcing Plate 2 reinforces the upper locking plate, thereby improving its stability and preventing slippage during operation. The horizontal sliding mechanism, the transverse sliding mechanism, and the vertical sliding mechanism work together to adjust the position of the detection head in the horizontal, vertical, and transverse directions.

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figure 1 , Figure 2 It includes a measuring platform 1, a horizontal sliding mechanism 2 on the measuring platform 1, a transverse sliding mechanism 3 on the upper end of the horizontal sliding mechanism 2, a vertical sliding mechanism 4 on the transverse sliding mechanism 3, a detection head 5 on the vertical sliding mechanism 4, and a locking mechanism 6 between the transverse sliding mechanism 3 and the measuring platform 1. The upper end of the locking mechanism 6 is connected to the transverse sliding mechanism 3, the lower end of the locking mechanism 6 is connected to the measuring platform 1, and it is connected to the horizontal sliding mechanism 2 through a connecting plate 8.

[0023] See Figure 2As shown, the horizontal sliding mechanism 2 includes an active support 21 and a driven support 22. Both the active support 21 and the driven support 22 are mounted on the measuring table 1. A fixed trajectory walking mechanism 23 is provided between the active support 21 and the measuring table 1. The fixed trajectory walking mechanism 23 is common in the current market. Its specific structure and working principle will not be described or limited in detail here. The active support 21 is moved by the fixed trajectory walking mechanism 23. The active support 21 moves by the active support 21 through the horizontal sliding mechanism 3, thereby realizing the horizontal movement of the detection head 5.

[0024] Combination Figure 1 , Figure 2 , Figure 4 As shown, the transverse sliding mechanism 3 includes a crossbeam 31. One end of the crossbeam 31 is mounted on the active support 21, and the other end of the crossbeam 31 is mounted on the driven support 22. A housing 32 is provided on the crossbeam 31. A horizontal walking drive mechanism 33 is provided between the crossbeam 31 and the vertical sliding mechanism 4. The horizontal walking drive mechanism 33 is quite common in the existing market. Its specific structure and working principle will not be described in detail or limited here. The horizontal walking drive mechanism 33 drives the vertical sliding mechanism 4 to slide on the crossbeam 31, thereby driving the detection head 5 to move in the transverse direction.

[0025] Looking back Figure 2 As shown, the vertical sliding mechanism 4 includes a mounting plate 41, which is slidably mounted on the crossbeam 31. The horizontal walking drive mechanism 33 is located between the mounting plate 41 and the crossbeam 31. A lifting vertical frame 42 is slidably mounted on the mounting plate 41. The upper end of the lifting vertical frame 42 is connected to the mounting plate 41 via a belt drive driver 43. The belt drive driver 43 is commonly found in the market. Its specific structure and working principle are not described or limited in detail here. The detection head 5 is mounted on the lower end of the lifting vertical frame 42. The belt drive driver 43 drives the lifting vertical frame 42 to slide on the mounting plate 41. The lifting vertical frame 42 drives the detection head 5 to move accordingly, thereby adjusting the height position of the detection head 5.

[0026] like Figure 4 As shown, the locking mechanism 6 includes a lower locking plate 61 and an upper locking plate 62. The lower locking plate 61 has a circular mounting hole 611 at both its upper and lower ends. The upper locking plate 62 has a circular mounting hole 621 at its upper end and a strip mounting hole 622 at its lower end. The circular mounting hole 611 at the lower end of the lower locking plate 61 is connected to the measuring platform 1 and the connecting plate 8 by a fixing bolt. The circular mounting hole 611 at the upper end of the lower locking plate 61 is connected to the strip mounting hole 622 by a fixing bolt. The circular mounting hole 621 is connected to the crossbeam 31.

[0027] In this embodiment, an L-shaped fixing plate 7 is installed on one side of the upper locking plate 62. The L-shaped fixing plate 7 is connected to the upper locking plate 62 by a fixing bolt. One end of the L-shaped fixing plate 7 is installed on the outer shell 32, which improves the connection stability between the upper locking plate 62 and the transverse sliding mechanism 3.

[0028] In this embodiment, the lower end of the upper locking plate 62 and the upper end of the lower locking plate 61 are both triangularly arranged. A reinforcing plate 9 is provided in the middle of the lower locking plate 61, and a reinforcing plate 10 is provided on the upper locking plate 62. By removing the fixing bolt between the upper locking plate 62 and the lower locking plate 61, the locking of the transverse sliding mechanism 3 is released, allowing the upper locking plate 62 to move with the crossbeam 31, which facilitates the subsequent reconnection between the lower locking plate 61 and the upper locking plate 62.

[0029] In this embodiment, four strip-shaped mounting holes 622 are provided, and the four strip-shaped mounting holes 622 are distributed in a matrix, so that the four corners of the contact surface between the lower locking plate 61 and the upper locking plate 62 are subjected to uniform force, thereby improving the stability of the connection.

[0030] In use, this utility model is as follows: During operation, the lower locking plate 61 and the connecting plate 8 are connected to the measuring platform 1 via fixing bolts. Then, the other end of the connecting plate 8 is connected to the active bracket 21 to lock the position of the horizontal sliding mechanism 2. Next, the lower locking plate 61 is connected to the upper locking plate 62 via fixing bolts, and the upper end of the upper locking plate 62 is connected to the crossbeam 31 to lock the position of the transverse sliding mechanism 3. One end of the L-shaped fixing plate 7 is installed on the upper locking plate 62, and the other end is installed on the outer shell 32 to improve the stability of the connection. By locking the positions of the transverse sliding mechanism 3 and the horizontal sliding mechanism 2, displacement during operation is prevented, ensuring the accuracy of the detection.

[0031] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
