Figure 3 is a partial cross-sectional view taken along line 3-3 of Figure 1.

In order to better understand the characteristics of the present creation, the present invention provides a preferred embodiment and is described below with reference to the drawings, please refer to Figures 1 to 3. The measuring device 1 is used to measure a gear set to be tested 90. The gear set 90 to be tested includes a first gear 91 and a second gear 92 that mesh with each other, and the first gear 91 is a helical gear and It is fixed to a gear connecting rod 93. The main components of the inventive gear positioning accuracy measuring device 1 include a body 10, a power source 20, a first angle encoder 30, a gear positioning seat 40 and a second angle encoder 50. The structure and relationship between each other are detailed below:

The body 10 includes a body 11 , a height adjusting member 12 is disposed on the seat body 11 , and a mounting seat 13 is disposed on the top of the height adjusting member 12 , wherein the mounting seat 13 has a U-shape and has two upright portions 131 , and An assembly portion 132 is provided on the top surface side of the mount 13. Thereby, the mount 13 can be moved up and down relative to the seat body 11 by the height adjusting member 12.

The power source 20 is a motor in this embodiment for rotating the first gear 91, which is stably fixed to the assembly portion 132. The power source 20 has a controller (not shown) and a power output shaft 22, and the controller is used to control the operation of the power source 20. The power output shaft 22 passes through the assembly portion 132 and sleeves the two bearings 133 for assembly. One of the upright portions 131 is provided with a connecting shaft 60 and another bearing 133. In addition, the end of the power output shaft 22 protrudes between the two upright portions 131, so that both ends of the gear connecting rod 93 are coaxially connected to the power output shaft 22 and a connecting shaft 60. It is added here that the connecting shaft 60 and the other bearing 133 are of an auxiliary nature, which are not essential components for the present invention.

The first angle encoder 30 is sleeved on the power take-off shaft 22 of the power source 20 and is coupled to the bearing 133 by its outer edge. The first angle encoder 30 is for measuring the rotation angle of the power output shaft 22, because the power output shaft 22 and the gear connecting rod 93 are coaxially connected to rotate synchronously, so the first angle encoder 30 can obtain the first gear 91. The angle of rotation.

The gear positioning base 40 has a fixing base 41, a turntable 42, a rotating rod bearing 44 and a table 45. The second gear 92 can be sleeved and assembled on the fixing base 41. The fixing base 41 is coaxially connected to the upper part of the turntable 42. The turntable 42 has a rotating lever (not shown) rotatably disposed on the base 45 through the rotating rod bearing 44. The base 45 is disposed on the base 11 and horizontally movable relative to the base 11. Therefore, the second gear 92 and the turntable 42 can rotate in synchronization.

The second angle encoder 50 is sleeved on the rotating rod and connected to the rotating rod bearing 44 by its outer edge. The second angle encoder 50 is used to measure the rotation angle of the rotating rod because the second gear 92 and the rotating rod are The rotation is synchronized, so that the rotation angle of the second gear 92 can be obtained.

In use, when the user wants to measure the positioning accuracy of the gear set on the indexing device, the user first performs the step of position adjustment, that is, the height of the first gear 91 is adjusted by the height adjusting member 12, and the gear positioning seat 40 is utilized. Adjusting the horizontal distance of the second gear 92 relative to the first gear 91 so that the first gear 91 and the second gear 92 are both at the same height and an appropriate horizontal distance to allow the first gear 91 to closely and smoothly engage the second gear 92. After the position adjustment is completed, the user can start the measurement operation.

In the measurement operation, the user uses the controller of the power source 20 to control the power output shaft 22 to rotate by a predetermined angle. At this time, the first angle encoder 30 that is sleeved on the power output shaft 22 will read the rotation angle. The value is returned to the controller. When the power output shaft 22 is rotated to the predetermined angle, the second gear 92 will be driven by the first gear 91 to rotate, and the rotation of the rotating rod of the turntable 42 is synchronously driven, so that the second angle encoder 50 reads. By measuring the angle value, the user can calculate the positioning accuracy of the gear based on the angle values measured by the first and second angle encoders 30, 50. The user can then repeat the above steps and use the obtained data to calculate the positioning repeat accuracy of the gear. Therefore, the user can judge the quality and performance of the gear set 90 to be tested by using the positioning accuracy of the gear and the positioning repeatability as an index. The entire measurement process is simple and easy to operate, so the user can quickly measure, and then the test can be tested and detected before the gear set is assembled into the indexing device, thereby reducing the occurrence of defective products.

Finally, it must be stated again that the present invention is disclosed in the foregoing embodiments. The constituent elements are merely illustrative and are not intended to limit the scope of the present invention. Other structural changes that are easily conceivable, or alternative changes with other equivalent elements, are also covered by the scope of the patent application.
