Description

Technical Field

[0001] This utility model relates to the field of product inspection technology, and in particular to a measuring tool for inspecting weld width. Background Technology

[0002] Weld width is an important inspection indicator in welding measurement. Consider a circular workpiece to be welded into a gear; the weld seam is a ring around the contact point between the workpiece and the inner ring of the gear. To measure the weld width, the center of the weld seam must be located, and the distance between the highest points of two weld points on a diameter passing through the center must be measured. This distance is the weld width.

[0003] However, existing technologies, such as the patent with patent number "202321160951.6" and patent name "A Weld Width Inspection Device" published on December 12, 2023, cannot measure the width of a circular weld.

[0004] Therefore, there is an urgent need for a measuring tool to inspect the weld width, specifically for measuring the weld width of this type of circular weld. Utility Model Content

[0005] This utility model provides a measuring tool for inspecting the weld width, which solves the problem of measuring the weld width after welding gears to the outer circumference of a circular workpiece.

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0029] like Figures 1 to 3 As shown, this utility model provides a measuring tool for inspecting weld width. Some specific embodiments are described below. Specifically, the measuring tool for inspecting weld width includes a worktable 1, on which a horizontal moving device 2 is installed. The horizontal moving device 2 moves in a straight line in the horizontal direction. A V-block 3 for fixing the workpiece is installed above the horizontal moving device 2. The V-block 3 is placed horizontally, and the workpiece enters and exits the V-block 3 in a horizontal direction. Since the opening of the V-block 3 gradually narrows, when the workpiece enters from the opening of the V-block 3, it will be positioned.

[0030] A longitudinal support rod 4 is fixedly installed on the workbench 1. A transverse support rod 5 is installed on the longitudinal support rod 4. A dial indicator 6 is movably installed on the transverse support rod 5, so that the dial indicator 6 can move on the transverse support rod 5 and change its installation position on the transverse support rod 5.

[0031] The longitudinal support rod 4 is located in the middle of the horizontal moving device 2. The horizontal moving device 2 moves the workpiece across the longitudinal support rod 4 to the left and right sides of the longitudinal support rod 4. Additionally, the measuring tool for inspecting the weld width includes a centering sleeve 7 for fixing to the top of the workpiece. In use, after positioning the workpiece in the V-block 3, the centering sleeve 7 is placed on the top of the workpiece. The centering sleeve 7 has a through hole 701 at its center. The diameter of the dial indicator 6's probe matches the diameter of the through hole 701. Adjusting the position of the dial indicator 6 ensures that its probe can pass through the through hole 701 of the centering sleeve 7, thus guaranteeing that the dial indicator 6 is positioned at the center of the workpiece.

[0032] Meanwhile, the measuring tool for inspecting the weld width also includes a digital display device 8. The digital display device 8 includes a magnetic scale 801, a magnetic scale sensing head 802, and a digital display 803. The digital display 803 is mounted on the longitudinal support rod 4 for easy observation. The digital display 803 can display the distance between the magnetic scale sensing head 802 and the magnetic scale 801. The magnetic scale 801 is fixed on the extension line of the movement trajectory of the horizontal moving device 2 on the worktable 1, and the magnetic scale sensing head 802 is mounted on the horizontal moving device 2 and can move along the movement trajectory.

[0033] After adjusting the dial indicator 6 to the center of the workpiece, the workpiece is moved using the horizontal moving device 2. This ensures that the dial indicator 6's trajectory above the workpiece follows its diameter. Then, the horizontal moving device 2 is pushed to move the dial indicator 6 to one side of the weld (e.g., the first measuring position 10). By fine-tuning the horizontal moving device 2, the highest point of the weld at this location is found using the dial indicator 6. At this point, the digital display 803 is zeroed. Then, the horizontal moving device 2 is pushed to move the workpiece, and the dial indicator 6 moves to the other side of the weld (e.g., the second measuring position 11). Again, by fine-tuning the horizontal moving device 2, the highest point of the weld at this location is found using the dial indicator 6. The reading on the digital display 803 then shows the width of the weld.

[0034] In addition to the above-mentioned technical features, a measuring tool for inspecting weld width is further characterized in that the direction of the V-block 3 in and out is perpendicular to the direction of the horizontal moving device 2, and the direction of the extension of the transverse support rod 5 is parallel to the direction of the V-block 3 in and out, which is more conducive to adjusting the dial indicator 6 to be located at the center of the workpiece.

[0035] In this specific embodiment, the horizontal moving device 2 includes a guide rail 201, a slider 202, and a support plate 203. The support plate 203 is mounted on the guide rail 201 via the slider 202, allowing the support plate 203 to move along the guide rail 201. The V-block 3 is fixed above the support plate 203. When the workpiece is placed in the V-block 3, the movement of the support plate 203 can also move the workpiece.

[0036] In some other embodiments, there are two guide rails 201, which are arranged in parallel to maintain the stability of the support plate 203. Stops 204 are installed on both the front and rear sides of the guide rails 201 to prevent the slider 202 from disengaging from the guide rails 201 due to excessive movement of the support plate 203.

[0037] Support legs 9 are installed under the workbench 1 to ensure the height and stability of the workbench 1.

[0038] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.
