Description

Technical Field

[0001] This utility model belongs to the field of gear processing technology, and more specifically, it relates to a tool for testing the meshing accuracy of zinc alloy gears in automotive seat gearboxes. Background Technology

[0002] During the manufacturing of car seats, a gearbox is installed inside the seat to facilitate seat adjustment. The gearbox is composed of various zinc alloy gears. The zinc alloy gears need to be manufactured with high precision to ensure the accuracy of gearbox meshing. After the zinc alloy gears are manufactured, they need to be inspected. When inspecting the inner diameter of the zinc alloy gears, a precision inspection tool is used. The zinc alloy gear is placed inside the inspection tool, and the inspection tool moves the zinc alloy gear to the position of the inspection ruler to check whether the inner diameter of the zinc alloy gear is qualified.

[0003] According to CN202220390017.2, this utility model relates to the field of gear processing technology, and in particular to a gear inner diameter detection device for precision gear processing. It solves the problem that in the prior art, the inner diameter of precision gears is measured manually using measuring tools. This traditional method is not only time-consuming and labor-intensive, but also significantly reduces the accuracy of gear inner diameter measurement. The gear inner diameter detection device for precision gear processing includes a frame, with a screw rotatably connected to the upper inner side of the frame. One end of the screw is threadedly connected to a first nut seat. The method proposed in this utility model uses a detection rod and a support plate to drive the gear to move, thereby enabling quick and intuitive detection of the gear's inner diameter. This avoids the problems of time-consuming, labor-intensive, and inaccurate manual measurement of gear inner diameter using measuring tools.

[0004] Based on the above, existing precision testing tools generally adopt a frame structure to protect the structural testing components inside. The support structure is used to install gears. To facilitate the testing of gears by the measuring ruler, the gears are generally installed on the side of the support. Because the gears are installed on the side of the support, the space inside the frame is limited, which makes it inconvenient for workers to pick up, place, and adjust the gears. This operational limitation affects the efficiency of the workers in testing the gears. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a tool for testing the meshing accuracy of zinc alloy gears in automotive seat gearboxes. This addresses the issue that existing accuracy testing tools typically employ a frame structure, protecting the structural testing components within it. A support structure is used to mount the gears, and to facilitate gear inspection with a measuring ruler, the gears are generally mounted on the side of the support. However, due to the limited space within the frame, operators face numerous inconveniences when handling, placing, and adjusting the gears, thus hindering the efficiency of gear testing.

[0006] The purpose and effectiveness of this utility model's zinc alloy gear meshing accuracy testing tool for automotive seat gearboxes are achieved through the following specific technical means:

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention employs a detection mechanism that allows workers to operate a width motor to slide a width support arm, adjusting the width of the support arm to facilitate placing the gear on it. Workers then operate a rotating turntable, which moves the gear toward a diameter scale, thereby detecting the diameter of the gear's inner end face. This allows workers to easily use detection tools to measure the gear's diameter.

[0015] This invention employs a placement and adjustment mechanism to allow the width support arm to rotate to the front side when it is not being tested on the right side. This facilitates the handling and placement of gears on the width support arm by staff, avoiding the inconvenience of installing gears from the side. When the gears are being tested, the width support arm automatically rotates the gears to face the diameter scale for testing, making it convenient for staff to use the testing tools.
