Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a gear assembly detection mechanism for reducers. Background Art

[0002] The reducer is a mechanical transmission device widely used in the industrial field. Its main function is to convert the input high-speed rotational motion into a lower speed and higher torque output, thereby meeting the different power transmission requirements of various mechanical equipment. In the manufacturing process of the reducer, the quality of gear assembly directly affects the overall performance and service life of the reducer. Traditional gear assembly inspection mainly relies on manual visual inspection or the use of simple measuring tools. This inspection method is inefficient, and the accuracy and consistency of the inspection results are difficult to guarantee.

[0003] The Chinese patent publication number is: CN216940295U discloses a gear assembly detection mechanism for a reducer. The patented technology is driven by a motor to drive the screw to rotate, and then drive the second slider threaded on the screw to move on the screw, thereby driving the movable plate to move back and forth. By setting the fixed plate and the detection plate at a suitable width, when the staff detects the assembled gear to be assembled, the detection plate can just cover the gear to be assembled, thereby detecting whether the gear to be assembled is exactly in the correct position on the reducer base.

[0004] Although the above patent can conveniently and quickly detect the gears to be assembled, in actual use, since the size and diameter of the detection plate and the detection groove on the fixed plate are fixed, the device can only detect gears of the same diameter, while the traditional reducer can install and replace gears of different sizes and transmission ratios. Therefore, the device cannot detect other gears in the reducer and has a small scope of application. Therefore, it is necessary to propose a gear assembly detection mechanism for a reducer to solve the above-mentioned problems. Utility Model Content

Stabilizing plates are fixedly connected to both sides of the bottom of the movable plate, and the stabilizing plates are slidably connected to the limit columns.

[0009] Furthermore, in order to adjust the support height of the gear to be detected in the reducer base, support threaded rods are fixedly connected on both sides of the surface of the mounting groove, and lifting tubes are threadedly connected on the surface of the support threaded rods. A support plate is rotatably installed on the top of the lifting tube, and through holes are opened on both sides of the bottom surface of the reducer base.

[0010] Furthermore, in order to realize the installation of the machine shaft in the reducer base, shaft holes are opened on both sides of the surface of the reducer base, and the center of the adjusting disk corresponds to the center of the shaft hole.

[0011] Furthermore, in order to achieve the position limiting of the support plate in the reducer base, the size of the support plate matches the through hole, and the width of the through hole matches the inner wall of the reducer base.
