Description

Technical Field

[0001] This utility model relates to the field of automotive parts inspection, specifically to an equipment for inspecting the appearance of automotive parts. Background Technology

[0002] Automotive parts, including various shaft parts, have different outer diameters and require inspection before leaving the factory, including visual inspection and dimensional inspection. Manual inspection requires a workbench equipped with a part positioning mechanism. After the part is positioned on the workbench, the worker visually inspects the part, or uses inspection tools to check the part's shape and dimensions. Utility Model Content

[0003] The technical problem solved by this utility model is: how to expand the range of parts that the positioning mechanism on the worktable can position.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a visual inspection mechanism for automotive parts, including a left support and a right support mounted on a worktable, a left rotating shaft pivotally connected to the left support, and a right rotating shaft pivotally connected to the right support. A left clamp is provided on the left rotating shaft, and a right clamp is provided on the right rotating shaft. The right support can be linearly displaced along the worktable, moving away from or close to the left support. The left clamp includes several left clamping blocks, which are distributed circumferentially along the left rotating shaft. The left clamping blocks are hinged to one end of the left rotating shaft, and one end of the left clamping block is hinged to one end of the left connecting rod. The other end of the left connecting rod is hinged to a left adjusting sleeve. The left adjusting sleeve is sleeved on the left rotating shaft, and a left fastening screw is provided on the left adjusting sleeve.

[0005] The right clamp includes several right clamping blocks, which are distributed circumferentially along the right rotation axis. The right clamping blocks are hinged to one end of the right rotation axis, and the right clamping blocks are hinged to one end of the right connecting rod. The other end of the right connecting rod is hinged to the right adjusting sleeve. The right adjusting sleeve is sleeved on the right rotation axis and is provided with a right fastening screw.

[0006] Both the left and right clamping blocks have curved surfaces that come into contact with the product.

[0007] According to the above technical solution, the left end of the product is fitted into the left clamp. The worker moves the right support so that the right end of the product is fitted into the right clamp. The worker then moves the left adjusting sleeve to the right, causing the left connecting rod to drive the left clamping block to rotate. Several circumferentially distributed left clamping blocks then close, clamping the left end of the product. The worker then moves the right adjusting sleeve to the left, causing the right connecting rod to drive the right clamping block to rotate. Several circumferentially distributed right clamping blocks then close, clamping the right end of the product. Afterward, the worker can rotate the product for visual inspection.

[0008] Because the contact surfaces of the left and right clamping blocks are curved, the left and right clamping blocks can hold products of various sizes by utilizing their rotation range, thus expanding the range of products that the workbench can inspect.

[0009] The workbench is equipped with a left support and a right support. One end of the threaded rod is pivotally connected to the left support, and the other end is pivotally connected to the right support. A knob is installed on the right support and connected to the threaded rod. A guide bar is provided on the side of the threaded rod. The right support is screwed onto the threaded rod and movably engages with the guide bar. When the worker rotates the knob, the threaded rod rotates, causing the right support to move linearly along the guide bar, moving away from or towards the left support.

[0010] Both the left and right rotating shafts are equipped with center positioning holes. When positioning the product, the left end of the product can be inserted first into the center positioning hole of the left rotating shaft, and the right end of the product can be inserted first into the center positioning hole of the right rotating shaft. After the product is supported, the worker then operates the left and right adjusting sleeves to clamp the left and right clamping blocks. When removing the product, the left and right clamping blocks release the product first, and then the worker removes the product from the center positioning holes of the left and right rotating shafts.

[0011] The left rotating shaft has a first hinge seat on the left side, the left clamp has a second hinge seat on the left side, and the left adjusting sleeve has a third hinge seat on the left side. The left clamp is hinged to the first hinge seat on the left side, one end of the left connecting rod is hinged to the second hinge seat on the left side, and the other end of the left connecting rod is hinged to the third hinge seat on the left side.

[0012] The right rotating shaft has a first right hinge seat on its end face, a second right hinge seat on its right clamping block, and a third right hinge seat on its right adjusting sleeve. The right clamping block is hinged to the first right hinge seat, one end of the right connecting rod is hinged to the second right hinge seat, and the other end of the right connecting rod is hinged to the third right hinge seat.

[0013] The left rotating shaft is pivotally connected to the left bracket via a bearing, and the right rotating shaft is pivotally connected to the right bracket via a bearing.

[0014] The left and right clamps of this utility model can not only hold the ends of shaft-type parts, but also position the conical ends of the product like open petals, so that the product is stable on the left and right clamps, which helps to expand the detection range of the worktable.
