Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a gear shaft pitch detection device. Background Art

[0002] A gear shaft refers to a mechanical part that supports a rotating part and rotates with it to transmit motion, torque or bending moment. After the gear shaft is processed, in order to ensure the accuracy of the gear shaft, the interval between the two gears on the gear shaft will be tested to ensure the quality of the finished gear shaft.

[0003] The existing detection method is to measure and detect with a ruler. The ruler measurement and detection is slow and inefficient. At the same time, workers are required to repeatedly pull and pull the ruler, which causes a large workload for workers and is not conducive to the processing and production of gear shafts. Therefore, in view of the current situation, it is necessary to improve it.

[0005] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, which are mainly manifested in the following aspects:

[0006] First, the diameters of the gears on the existing gear shafts are different. When the diameter difference between two adjacent gears is large, the existing device cannot quickly detect the distance between the two gears with a large diameter difference, thereby reducing the detection efficiency of the gear pitch.

[0007] Second, due to the different shaft diameters at both ends of the gear shaft, the existing detection device cannot ensure the horizontal placement of the gear shaft when fixing the gear shaft, which affects the detection accuracy of the distance between the two gears.

[0008] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
