Detailed Description
The three-coordinate measuring clamp quick-change mechanism comprises a three-coordinate workbench 1, wherein a three-coordinate clamp quick-change platform 2 is arranged on the three-coordinate workbench 1, and mounting areas 21 for different three-coordinate clamps 3 are arranged on the three-coordinate clamp quick-change platform 2.
Further, the three-coordinate fixture quick-change platform 2 is arranged on the three-coordinate workbench 1 through the workbench connecting hole 4, and the three-coordinate fixture quick-change platform 2 is provided with an installation threaded hole 4 and a positioning pin sleeve 5 for installing the three-coordinate fixture 3.
Furthermore, a marking line 6 is arranged between the mounting threaded holes 4 of the mounting area 21 of the three-coordinate fixture quick-change platform 2, and the marking line 6 is arranged according to the bottom profile of the three-coordinate fixture 3, so that the marking line 6 is covered when the three-coordinate fixture 3 is mounted on the three-coordinate fixture quick-change platform 2.
Furthermore, a plurality of concave narrow grooves 7 are formed between the adjacent mounting threaded holes 4 of the three-coordinate clamp quick-change platform 2, the narrow grooves 7 correspond to the bottom profiles of different three-coordinate clamps 3, the narrow grooves 7 in different paths form a plurality of different marking areas, and the areas are distinguished by marks in different colors.
The invention will be further explained below for a better understanding of the invention: 1) the quick change mechanism of the three-coordinate measuring clamp is arranged on the three-coordinate workbench 1 through the workbench connecting hole 4, and the quick change mechanism of the arranged three-coordinate clamp is used as an installation platform of the three-coordinate clamp and can not be detached under general conditions unless damaged and replaced or special parts need to be measured; and a certain number of three-coordinate clamp mounting threaded holes 4, three-coordinate clamp positioning pin sleeves and pin sleeve fastening screws 5 are arranged at different positions of the three-coordinate clamp quick-changing mechanism. The three-coordinate fixture positioning pin sleeve is used for accurately positioning a three-coordinate measuring fixture, and the positioning pin sleeve can be conveniently replaced for preventing the failure of a positioning pin hole caused by frequent switching.
2) Mounting a three-coordinate measuring clamp: the three-coordinate clamp is positioned on a three-coordinate clamp quick-changing mechanism through a positioning pin 5, the positioning pin and the positioning hole are in IT 7-level tolerance fit, the positioning is accurate, and the clamp is locked on the mechanism through a fastening screw 5; the three-coordinate fixture A and the three-coordinate fixture B are arranged at different positions of the three-coordinate measuring fixture quick-change mechanism, because the distribution areas of the positioning pin sleeves are different for different types of products, each type of product has a specific area, the distance and the direction between the positioning pin sleeves in the specific areas are different, and the distance and the direction between the threaded holes are also different, so that the error of the fixture mounting position is avoided.
3) The sizes of the positioning pin sleeve and the threaded hole are consistent, the positioning pin and the screw of the mounting and measuring clamp can be shared, and when the three-coordinate clamp A is switched to the three-coordinate clamp B, the fastening screw 5 only needs to be loosened, the positioning pin 5 is pulled out, and the three-coordinate clamp A is taken away. The disassembled fastening screw and the positioning pin 5 can be directly used for installing the three-coordinate fixture B, extra workload can not be caused, and the installation fixture is simpler and more convenient due to the positioning of the positioning pin 5.
4) The invention further sets the marking lines 6, because different mounting modes can be used for mounting the three-coordinate clamp 3 when the three-coordinate clamp 3 is mounted on the three-coordinate clamp quick-change platform, but only one correct mounting mode exists, at this time, if the mounting mode is not familiar, the mounting error of the three-coordinate clamp 3 is easily caused, therefore, the marking lines 6 are set, if the marking lines 6 are correctly mounted, all the marking lines 6 are covered, and if the marking lines 6 are exposed, the mounting error is represented, and the mounting efficiency and the mounting accuracy are greatly improved by the mode, so that a series of problems caused by the wrong mounting are avoided.
5) In order to further improve the installation flexibility, different marking areas are arranged aiming at the condition that different types of three-dimensional clamps 3 can be installed in the same installation area, and the different marking areas are effectively distinguished, so that the assembly efficiency of the three-dimensional clamp installation structure is further improved, and the assembly accuracy is also greatly improved.
