[0002] The three-dimensional coordinate measuring machine is a high-precision measuring tool commonly used in industries such as mechanical engineering and electronic instruments. It has the advantages of high degree of automation, good applicability and ease of use. The fixing mechanism of the three-dimensional coordinate measuring machine refers to the structure that fixes the workpiece on the three-dimensional coordinate measuring machine. Its function is to ensure the stability of the workpiece during measurement.

[0003] However, existing CMM fixing mechanisms present the following challenges: Because objects vary in size, the CMM requires an adjustable mechanism to facilitate measurement of objects of varying sizes. However, existing CMM fixing mechanisms are inconveniently adjustable to suit the size of the object. This makes it difficult to secure and move objects of varying sizes to the appropriate height, hindering the CMM's ability to measure objects of varying sizes and reducing the device's practicality. To address these challenges, an innovative design based on the existing CMM fixing mechanism was developed. Utility Model Content

[0007] A supporting table is fixedly installed on the upper end of the plate sleeve, a positioning plate is fixedly connected to the upper surface end of the supporting table, and a limiting mechanism is installed on the side outer wall of the positioning plate.

[0008] Preferably, the bracket and the transmission sleeve are rotationally connected, the transmission sleeve and the transmission rod are threaded, and the directions of the threads provided on the outer wall of the transmission rod are symmetrically distributed about the longitudinal center axis of the bracket.

[0028] See also Figure 1-5 The utility model provides a technical solution: a fixing mechanism of a three-coordinate measuring machine, including a three-coordinate measuring machine body 1, a bracket 2 is fixedly installed on the surface of the three-coordinate measuring machine body 1, a transmission sleeve 3 is movably connected to the inner wall of the upper end of the bracket 2, and transmission rods 4 are respectively provided on the inner walls of both ends of the transmission sleeve 3, a gear block 5 is fixedly installed on the end of the transmission rod 4, and a clamping rod 6 is fixedly connected to the lower surface of the gear block 5.

[0029] A square plate 7 is fixedly mounted on the surface of the three-coordinate measuring machine body 1 on the side of the bracket 2 . A plate sleeve 8 is sleeved on the outer wall of the square plate 7 . A tooth protrusion 9 is fixedly provided on the outer wall of the side of the plate sleeve 8 .

[0030] A support table 10 is fixedly mounted on the upper end of the plate sleeve 8 , a positioning plate 11 is fixedly connected to the upper surface end of the support table 10 , and a limiting mechanism 12 is mounted on the side outer wall of the positioning plate 11 .

[0031] In this example, the bracket 2 and the transmission sleeve 3 are rotationally connected, the transmission sleeve 3 and the transmission rod 4 are threaded, and the direction of the thread set on the outer wall of the transmission rod 4 is symmetrically distributed about the longitudinal center axis of the bracket 2, which makes it convenient for the user to rotate the transmission sleeve 3 so that the transmission rod 4 moves toward or opposite to the transmission sleeve 3 at the same time.

[0032] In this example, the tooth block 5 and the tooth protrusion 9 are engaged with each other, and the clamping rod 6 and the bracket 2 form a sliding structure, so that when the transmission rod 4 moves, the tooth block 5 moves. At this time, the tooth block 5 drives the clamping rod 6 to slide relative to the bracket 2, so that the tooth block 5 moves stably, and the support table 10 is fixed through the engagement of the tooth block 5 and the tooth protrusion 9.

[0033] In this example, the square plate 7 and the plate sleeve 8 are slidably connected. The square plate 7 is symmetrically arranged about the longitudinal center axis of the bracket 2, so that when the support table 10 moves vertically for height adjustment, the support table 10 drives the plate sleeve 8 to slide relative to the square plate 7.

[0034] The limiting mechanism 12 in this example includes a limiting rod 1201, a transmission frame 1202 and a splint 1203. The limiting rod 1201 is movably mounted on the outer side wall of the positioning plate 11. The outer wall of the limiting rod 1201 is sleeved with a transmission frame 1202. The side of the transmission frame 1202 is fixedly connected with a splint 1203, which facilitates the limiting of items placed on the support table 10 through the limiting mechanism 12.

[0035] In this example, the limit rod 1201 and the positioning plate 11 are rotatably connected, the limit rod 1201 and the transmission frame 1202 are threadedly connected, the transmission frame 1202 and the positioning plate 11 are slidingly arranged, and the splint 1203 and the support table 10 are slidably connected, so that the user can rotate the limit rod 1201 to make the transmission frame 1202 move along the limit rod 1201, thereby allowing the transmission frame 1202 to slide relative to the positioning plate 11. At this time, the transmission frame 1202 drives the splint 1203 to slide relative to the support table 10, so that the splint 1203 moves to fit the object, thereby completing the limitation of the object.

[0036] Working principle: According to Figure 1-5 As shown, the user adjusts the height of the support table 10 according to the size of the item. At this time, the user holds the support table 10 with one hand and rotates the transmission sleeve 3 with the other hand. Then the transmission rod 4 moves toward the transmission sleeve 3 at the same time. Next, the transmission rod 4 drives the gear block 5 to move and disengage from the gear protrusion 9. At the same time, the gear block 5 drives the clamping rod 6 to slide relative to the bracket 2. Then the user moves the support table 10 vertically. At this time, the support table 10 drives the plate sleeve 8 to slide relative to the square plate 7. When the height adjustment of the support table 10 is completed, the user stops moving the support table 10 and rotates the transmission sleeve 3 in the opposite direction. Then the gear block 5 moves in the opposite direction at the same time. Next, the gear block 5 moves and engages with the gear protrusion 9, thereby limiting the support table 10. At this time, the support table 10 completes the height adjustment, making it easy to adjust the height of the device according to the size of the item. The size of the items is adjusted to the appropriate measuring height, and then the user places the items on the support table 10, and then the user moves the items to fit the side wall of the support table 10, and then the user rotates the limit rod 1201, and then the transmission frame 1202 moves along the limit rod 1201, and at the same time the transmission frame 1202 slides relative to the positioning plate 11, and then the transmission frame 1202 drives the splint 1203 to move. At this time, the splint 1203 moves relative to the support table 10 to fit the items, thereby completing the positioning of items of different sizes on the device, and then the user starts the three-dimensional coordinate measuring body 1 to measure the fixed items, so the device is easy to adjust according to the size of the items, so that it is convenient for the device to fix items of different sizes and move the items to the appropriate height, which makes it convenient for the three-dimensional coordinate measuring machine to measure items of different sizes.
