Description

Technical Field

[0001] The utility model relates to the technical field of three-coordinate adjustment, in particular to a three-coordinate adjustment structure. Background Art

[0002] When manufacturing, testing or developing machinery in industries such as molds, mobile phone accessories, stampings, watches, and auto parts, the requirements for the quality and precision of workpieces are getting higher and higher. It is necessary to accurately measure the coordinates of points on the surface of the workpiece in the x, y, and z directions, which requires the use of a three-coordinate measuring machine (also known as a three-coordinate measuring bed).

[0003] The three-dimensional coordinate measuring machine is one of the most effective methods for measuring and obtaining dimensional data, because it can replace a variety of surface measuring tools and expensive combination gauges, and reduce the time required for complex measurement tasks from hours to minutes, which is an effect that other instruments cannot achieve. The three-dimensional coordinate measuring machine mainly includes a horizontal workbench, a data processor, a mechanical system that moves in the x, y, and z directions on the workbench, a measuring axis that moves in the z-axis direction, and a fixed probe at the lower end of the measuring axis.

[0004] However, the existing three-coordinate fine-tuning device generally uses a cylinder and a spring to limit the transmission component. However, due to the elastic effect of the spring, the limit fixation of the transmission device is not stable enough, which affects the fine-tuning accuracy. Utility Model Content

[0009] Preferably, a pointer is provided at one end of the right side of the light rod outside the box body.

[0010] Preferably, the limiting structure includes a third gear arranged in the box body, the third gear is located on the upper side of the first gear and meshes with the first gear, a rotating rod is provided in the middle of the third gear, the right end of the rotating rod is rotatably inserted in the box body, the left end passes through the shell extension slide groove, and is rotatably inserted on the left side wall of the slide groove, and a yield groove is opened in the middle of the pressure block corresponding to the rotating rod, and when the pressure block moves upward, the bottom of the yield groove can abut against the rotating rod.

[0011] Preferably, the bottom of the give way groove is arranged on an anti-slip pad corresponding to the rotating rod.

[0012] Preferably, an arc-shaped abutment groove is provided on the lower side of the pressing block corresponding to the polished rod.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model provides a three-coordinate adjustment structure, which drives a pressure block to move downward by rotating a threaded rod, and cooperates with a rotating roller and a roller to clamp and fix the light rod without affecting its rotation. When the pressure block descends, the bottom of the yield groove leaves the rotating rod, thereby releasing the abutment limit on the rotating rod. At this time, the knob can be rotated to cooperate with the pointer to perform stable adjustment under the condition that the rotating roller and the roller clamp and fix the light rod. After the adjustment is completed, the pressure block is moved up to the bottom of the yield groove and abuts on the rotating rod by rotating the threaded rod. Since the threaded connection of the threaded rod has a self-locking function, it cooperates with the anti-slip pad to limit the third gear. Due to the meshing connection, the first gear and the second gear remain stationary, thereby improving the stability of the transmission device and maintaining the accuracy of adjustment.
