Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment auxiliary tools, in particular to a gauge block bracket structure for a three-coordinate measuring machine. Background Art

[0002] In order to ensure the accuracy and reliability of the three-dimensional coordinate measuring machine during the measurement process, regular calibration work is essential. In the calibration process, the gauge block is an important reference tool, and its accuracy and stability directly affect the accuracy of the calibration results. Therefore, there are strict requirements for the placement, fixation and calibration operations of the gauge block. The existing gauge block bracket structure still has some problems and shortcomings in practical applications. First, the traditional gauge block bracket structure often has a single function and can only meet the needs of gauge block fixation at a specific angle. In complex calibration work, it is necessary to frequently replace the bracket or adjust the position of the gauge block, which increases the complexity and time cost of the operation. Secondly, some bracket structures take up a large space when stored, which is not convenient to carry and store. This problem is particularly prominent in mobile measurement or on-site measurement. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of the utility model is to provide a gauge block bracket structure for a three-coordinate measuring machine.

[0004] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a three-coordinate measuring machine gauge block bracket structure, including a base, a placement plate is rotatably connected to the base through a first rotating shaft, and a fastening clamp and a limit column for fixing the gauge block body are provided on the placement plate to ensure the stability of the gauge block during the measurement process. Support frames are rotatably installed on both sides of the placement plate through a second rotating shaft, and the ends of the support frames are threadedly connected with fixing bolts. Storage grooves and adjustment grooves are provided on both sides of the base corresponding to the fixing bolts, and the fixing bolts can be inserted into the storage grooves or the adjustment grooves. The storage grooves are used for folding and storing the bracket structure, and the adjustment grooves are used to adjust the opening angle of the placement plate.

[0005] As a preferred solution of the utility model, a crossbeam is installed equidistantly between the two side plates of the base, and a stepped groove is opened on the crossbeam. The stepped groove is a through groove that can be used to screw in bolts and cooperate with the threaded holes on the three-coordinate table to fix the base for more convenient use.

[0006] As a preferred solution of the utility model, a push plate for pushing up the placement plate is integrally formed at the end of the placement plate, so that the user can easily unfold or fold the placement plate.

[0007] As a preferred solution of the utility model, the adjustment grooves are respectively opened at the thirty-degree, forty-five-degree and ninety-degree positions supported by the placement plate to meet the needs of fixing the gauge block at different angles.

[0008] As a preferred solution of the utility model, a gasket is mounted on the fixing bolt to increase the fixing effect with the adjustment slot or the storage slot and improve the stability of the bracket structure.

[0009] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0010] The utility model provides a first rotating shaft and a second rotating shaft so that the placement plate can be flexibly rotated, and the multi-angle fixation of the placement plate is achieved through the cooperation of the fixing bolt and the adjusting groove, so as to meet the fixing requirements of the gauge block at different angles and improve the functionality of the bracket structure. By providing a storage groove, the bracket structure can be folded and stored when not in use, which reduces the occupied space and is convenient for carrying and storage. The fastening clamp and the limit column provided on the placement plate can ensure the stability of the gauge block during the measurement process and prevent position deviation due to vibration or external force. The crossbeam and step groove provided on the base can be used to fix the base, which is convenient for use. BRIEF DESCRIPTION OF THE DRAWINGS
