Description

Technical Field

[0001] This utility model relates to the field of gear inspection technology, and in particular to a tool for rapid inspection of gear curvature. Background Technology

[0002] In the gear manufacturing industry, half-shaft gears are core components of transmission systems. The machining accuracy of their arc surfaces directly determines the smoothness of gear meshing transmission, load-bearing capacity, and service life, and is a key indicator for product quality control.

[0003] Currently, the inspection of gear arc surfaces mainly relies on precision measuring instruments such as dial indicators and coordinate measuring machines (CMMs), or on general-purpose measuring tools for dimensional comparison. These inspection methods are widely used in traditional production scenarios. While precision instruments such as CMMs can achieve high-precision quantitative measurements, they require standardized inspection environments and workstations. General-purpose measuring tools, on the other hand, require operators to manually read and calculate dimensions based on drawings to determine the radius of curvature and contour accuracy of the gear arc surface.

[0004] However, the existing methods mentioned above have low efficiency in gear inspection, cumbersome operation procedures for precision instruments, and long reading and analysis time for general measuring tools. They cannot meet the full inspection requirements in mass production scenarios and are difficult to adapt to the actual demand for online rapid inspection on the production site. Utility Model Content

[0005] The purpose of this utility model is to provide a rapid gear curvature detection tool, which solves the problems of low gear detection efficiency, cumbersome operation process of precision instruments, long time consumption of reading and analysis of general measuring tools in the prior art, which cannot meet the full inspection requirements in mass production scenarios and are difficult to adapt to the actual requirements of online rapid detection on the production site.

[0006] To achieve the above objectives, this utility model employs a gear curvature rapid detection tool, comprising a pin, an arc gauge body, and a locking member. The pin is attached to the arc gauge body and located on one side of the arc gauge body. The pin has a first through hole, and the arc gauge body has a second through hole. The locking member is connected to the pin and the arc gauge body respectively, and moves through the first through hole and the second through hole in sequence.

[0007] The locking component includes an internal hexagonal head screw and a hexagonal nut. The hexagonal head screw is movably connected to the pin and the arc gauge body, and sequentially passes through the first through hole and the second through hole. The hexagonal nut is sleeved on the outside of the hexagonal head screw and is threadedly engaged with the hexagonal head screw.

[0008] The end of the pin has a guiding arc surface.

[0009] This utility model discloses a rapid gear curvature detection tool. During operation, the pin and the arc gauge body are assembled. The arc gauge body and the pin are brought into contact, and then a locking member is used to movably connect the pin and the arc gauge body. The locking member passes through the first and second through holes, ensuring the arc gauge body and the pin are tightly and fixedly assembled into a single unit. Next, the pin is inserted into the center hole of the half-shaft gear being measured, limiting the movement of the X and Y axes and ensuring its rotation along the Z axis. The standard arc working surface below the arc gauge body is then placed onto the arc portion of the half-shaft gear to be measured. Since the curvature of the gauge is standard and the curvature of the workpiece is machined, the two form a "fitting pair." Under standard light (or by touch), the measurement is completed. By observing the contact gap between the working surface of the arc gauge and the measured surface of the workpiece, the following criteria are applied: Acceptance is determined by the tight fit between the two surfaces, with almost no visible light gap, or a uniform and extremely small gap (within the allowable tolerance range). Acceptance is determined by the presence of obvious, uneven light gaps, indicating that the workpiece's arc radius is too large, too small, or irregular, thus classifying it as a defective product. This method simplifies complex dimensional tolerance judgments into a straightforward qualitative judgment of "light transmission," avoiding human error in readings. It allows ordinary workers to quickly complete full inspections of large batches of products without the need for complex instruments or skilled technicians, greatly improving inspection efficiency, reducing quality control costs, and meeting the actual needs of rapid online inspection in production sites.

[0014] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0015] Please see Figure 1 and Figure 2 This utility model provides a tool for rapid detection of gear curvature: it includes a pin 101, an arc gauge body 102, and a locking member. The pin 101 is attached to the arc gauge body 102 and located on one side of the arc gauge body 102. The pin 101 has a first through hole 103, and the arc gauge body 102 has a second through hole 104. The locking member is connected to the pin 101 and the arc gauge body 102 respectively, and moves through the first through hole 103 and the second through hole 104 in sequence.

[0016] In this embodiment, during operation, the pin 101 and the arc gauge body 102 are assembled. This is achieved by placing the arc gauge body 102 against the pin 101, and then using a locking member to movably connect the pin 101 and the arc gauge body 102. The locking member passes through the first through hole 103 and the second through hole 104, ensuring that the arc gauge body 102 and the pin 101 are tightly and fixedly assembled into a single unit. Next, the pin 101 is inserted into the center hole of the measuring half-shaft gear, limiting the movement of the X and Y axes and ensuring its Z-axis rotation. The standard arc working surface below the arc gauge body 102 is then attached to the arc portion of the half-shaft gear to be inspected. Since the gauge's curvature is standard and the workpiece's curvature is machined, the two form a "fitting pair." Under standard light source (or by touch), observe the contact gap between the working surface of the arc gauge and the measured surface of the workpiece. Acceptance criteria: If the two are tightly fitted together with almost no visible light gap, or the gap is uniform and extremely small (within the allowable tolerance range), the arc machining of that part of the workpiece is acceptable. Failure criteria: If obvious, uneven light gaps are visible, the workpiece's arc radius of curvature is too large, too small, or irregular, indicating a defective product. This method simplifies complex dimensional tolerance judgments into a straightforward qualitative judgment of "light transmission," avoiding human reading errors. It allows ordinary workers to quickly complete full inspection of large batches of products without complex instruments or skilled technicians, greatly improving inspection efficiency, reducing quality control costs, and meeting the actual needs of online rapid inspection in production sites.

[0017] Furthermore, the locking component includes an internal hexagonal head screw 105 and a hexagonal nut 106. The hexagonal head screw is movably connected to the pin 101 and the arc gauge body 102 respectively, and sequentially passes through the first through hole 103 and the second through hole 104. The hexagonal nut 106 is sleeved on the outside of the hexagonal head screw and is threadedly engaged with the hexagonal head screw.

[0018] In this embodiment, when assembling the pin 101 and the arc gauge body 102, the arc gauge body 102 is first attached to the pin 101, and then the internal hexagonal head screw 105 is used to penetrate the first through hole 103 and the second through hole 104. Then, the hexagonal nut 106 is used to tightly fix the arc gauge body 102 and the pin 101 into a whole.

[0019] Furthermore, the end of the pin 101 has a guiding arc surface 107.

[0020] In this embodiment, by providing the guide arc surface 107 at the end of the pin 101, the pin 101 can easily enter the half-shaft gear through the guide arc surface 107, making the operation simple.

[0021] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
