Description

Technical Field

[0002] A coordinate measuring machine (CMM) is a precision machine mainly composed of a main mechanical system, a probe system, an electrical control hardware system, and a data processing software system. It is used to measure and obtain dimensional data. In order to ensure the accuracy of the CMM during measurement, error adjustment is often required.

[0003] A Chinese patent with publication number CN221764424U discloses an error adjustment device for a coordinate measuring machine. The key technical points are: a base with a disassembly / assembly assembly on top; a centering assembly fixedly mounted on top of the disassembly / assembly assembly; the centering assembly including a support rod and a top plate; the support rod fixedly mounted on top of the disassembly / assembly assembly; the top plate fixedly connected to the top of the support rod; a gripper slidably connected to the top of the top plate; a connecting rod rotatably connected to the bottom of the gripper; a turntable rotatably connected to the bottom of the connecting rod; and a pulley fixedly mounted on the bottom of the turntable. This die-casting mold, through the support rod, top plate, gripper, connecting rod, turntable, pulley, connecting frame, and power assembly, can center the object to be measured, ensuring it is in the exact center. This effectively solves the problem of errors that easily occur during manual placement and reduces the impact of errors on normal use, resulting in better performance.

[0004] Existing technologies often have the following drawbacks: after adjusting the coordinate measuring machine (CMM) using its error adjustment device, it is usually stored by simply placing it on the ground.

[0032] The specific settings and functions of the shielding device 4 and the control device 5 will be explained in detail below.

[0033] Reference Figures 1-4 As shown in this embodiment: the shielding device 4 includes four shielding plates 41, all four shielding plates 41 are mounted on the upper surface of the adjusting plate 3, the inner wall of the adjusting plate 3 is threaded with a fixing screw 49, the surface of the fixing screw 49 is fixedly connected with a tray 48, and the lower surface of each of the four shielding plates 41 is fixedly connected with an arc-shaped plate 42. By setting the shielding plates 41 and the arc-shaped plates 42, the surface of the adjusting plate 3 can be shielded. By setting the fixing screws and the tray 48, the shielding plates 41 can be easily installed. The inner walls of each of the four shielding plates 41 are slidably connected with two sliding plates 43, and the upper surfaces of each of the eight sliding plates 43 are fixedly connected with a control plate 44, which is slidably connected to the inner wall of the shielding plates 41. By setting the sliding plates 43, the shielding plates 41 can be easily installed, and by setting the control plates 44, the sliding plates 43 can be easily controlled to move.

[0034] Each of the four cover plates 41 has two fixed plates 47 fixedly connected to its upper surface. Each of the eight fixed plates 47 has a sliding rod 45 slidably connected to its inner wall, and the sliding rod 45 is fixedly connected to the control plate 44. The sliding rod 45, slidably connected to the inner wall of the fixed plate 47, can move. By setting the fixed plates 47, the stability of the sliding rod 45's movement can be improved. A first spring 46 is fitted onto the surface of the sliding rod 45, and both ends of the first spring 46 are fixedly connected to the fixed plates 47 and the control plate 44, respectively. By setting the fixed plates 47, the first spring 46 can be easily installed, and by setting the first spring 46, the position of the sliding rod 45 can be restricted.

[0035] Reference Figure 1 and Figure 2 as well as Figure 5 and Figure 6 As shown, specifically, the control device 5 includes eight limiting plates 51, all of which are fixedly connected to the end of the slide rod 45 away from the control plate 44. Two baffles 52 are slidably connected to the upper surfaces of the four cover plates 41. By setting the baffles 52 and limiting plates 51, the position of the slide rod 45 can be restricted, facilitating the installation of the cover plates 41. Each of the four cover plates 41 has a groove on the side near the baffle 52, and a slider 54 is slidably connected to the surface of the groove on each of the four cover plates 41. A rectangular plate 53 is fixedly connected to the upper surface of the slider 54, and the rectangular plate 53 is fixedly connected to the baffle 52. By setting the slider 54, the rectangular plate 53 can be connected to the cover plate 41 while ensuring that the rectangular plate 53 can move. By setting the rectangular plate 53, the movement of the baffle 52 can be easily controlled.

[0036] A fixing rod 55 is slidably connected to the inner wall of the slider 54. The fixing rod 55 is fixedly connected to the surface of the groove on the cover plate 41. A second spring 56 is sleeved on the surface of the fixing rod 55. The two ends of the second spring 56 are fixedly connected to the cover plate 41 and the slider 54, respectively. By setting the fixing rod 55, the position of the second spring 56 can be restricted. By setting the second spring 56, the position of the slider 54 can be restricted.

[0037] Working principle: When using the error adjustment device of a coordinate measuring machine (CMM), first install the base 1 to the desired position, then connect the adjustment plate 3 to the base 1 using the connecting plate 2, and then adjust the CMM. After using the error adjustment device, first move the fixing screw 49 closer to the adjustment plate 3 to install the tray 48 onto the adjustment plate 3. Then move the control plate 44 to drive the slide rod 45 to slide on the inner wall of the fixing plate 47 to adjust the position of the slide plate 43. Next, move the cover plate 41 and the arc plate 42 closer to the adjustment plate 3. After installing the cover plate 41, release the control plate 44. Under the action of the first spring 46, the slide plate 43 moves away from the fixing plate 47, completing the installation of the cover plate 41. By setting the cover device 4, the surface of the adjustment plate 3 can be covered after using the error adjustment device to adjust the CMM, minimizing dust accumulation on the surface of the adjustment plate 3 during the storage of the error adjustment device, thus facilitating the use of the error adjustment device.

[0038] When the cover plate 41 needs to be installed, first move the rectangular plate 53 so that the slider 54 slides on the surface of the fixed rod 55. Then move the slide plate 43 through the limiting plate 51 so that the limiting plate 51 moves closer to the baffle 52. Release the rectangular block. Under the action of the elastic force of the second spring 56, the rectangular block pushes the baffle 52 to move closer to the limiting plate 51, thus restricting the position of the limiting plate 51 and the position of the slide plate 43. After the cover plate 41 is installed, move the rectangular plate 53 away from the limiting plate 51 to release the restriction on the position of the limiting plate 51. By setting the control device 5, the position of the slide plate 43 can be easily restricted during the installation of the cover plate 41, reducing the complexity of the installation of the cover plate 41 for the workers and making the installation of the cover plate 41 more convenient.
