Description

Technical Field

[0001] This utility model relates to a tooling for detecting runout of disc-type products. Background Technology

[0002] Disc-type products (such as disc-type product 20 described in the document) are widely used in mechanical transmission, aerospace, automotive manufacturing, and other fields. Their end-face runout (i.e., radial or axial deviation during rotation) is a key indicator for evaluating product accuracy and reliability. High-precision runout detection ensures product stability and lifespan under high-speed operation. However, disc-type products often have complex geometries (such as the central connecting hole 21 and irregular end faces), which poses a significant challenge to the inspection process: tooling is required to accurately simulate the rotational state and provide a stable reference plane to avoid measurement errors.

[0003] Existing tooling often uses rigid fixed supports (such as four-point positioning tables), which cannot dynamically compensate for the gap error between the bottom surface of the workpiece and the support surface. This causes the workpiece to tilt during initial installation, resulting in false runout signals. In view of this, this utility model proposes a runout detection tooling for disc-type products to solve the above problems. Utility Model Content

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Example:

[0042] like Figure 1-12 As shown, this embodiment proposes a runout detection fixture for disc-type products, used to detect disc-type products 20, including:

[0043] Base assembly 40, the base assembly 40 includes a base plate 42 and a standard turntable 41 disposed in the middle of the base plate 42;

[0044] A leveling and positioning component 30 is mounted on a standard turntable 41. The leveling and positioning component 30 includes three sets of height adjustment modules 32, and each of the three sets of height adjustment modules 32 is provided with a support plate 31 for placing the disc shaft product 20.

[0045] The detection execution component 10 includes a guide rail base 11 fixed to the base plate 42, a vertical guide rail 12 vertically arranged on the guide rail base 11, a vertical slider 123 slidably engaged with the vertical guide rail 12, a transverse guide rail 13 mounted on the vertical slider 123, and a transverse slider 132 slidably engaged with the transverse guide rail 13; a dial indicator is provided on the transverse slider 132.

[0046] In this case, the dial indicator is installed vertically on the horizontal slider 132 to inspect the upper and lower end faces of the disc shaft product 20. During the inspection, the value of the dial indicator is recorded to determine whether the end face to be inspected is flat.

[0047] In this embodiment, when inspecting the end face of the disc shaft product 20, the support plate 31 is first leveled by the inspection execution component 10. When the top surface of the support plate 31 is uneven, the support plate 31 is adjusted by three sets of height adjustment modules 32 until the top surface of the support plate 31 is level. Then, the disc shaft product 20 is placed on the support plate 31. The bottom end of the disc shaft product 20 is then leveled by the inspection execution component 10. After leveling, the disc shaft product 20 is fixed so that the bottom end of the disc shaft product 20 is parallel to the top end of the support plate 31. Then, the top end of the disc shaft product 20 is inspected for runout by the inspection execution component 10 again.

[0048] Of course, when the test execution component 10 is leveling the end face, the dial indicator on the test execution component 10 needs to be in contact with the end face, and the standard turntable 41 needs to be rotated. When the dial indicator shows a value jump, adjustments need to be made until the end face being tested is in a horizontal state when the standard turntable 41 is rotated.

[0049] Of course, the detection execution component 10 adopts a composite guide rail structure to drive the detection dial indicator to achieve precise positioning in three-dimensional space. The vertical guide rail 12 and its vertical slider 123 realize the adjustment of the detection height, and the horizontal guide rail 13 and its horizontal slider 132 realize the adjustment of the detection horizontal position.

[0050] The leveling and positioning assembly 30, composed of three sets of independently adjustable height adjustment modules 32, together with the detection and execution assembly 10, can accurately level the top surface of the support plate 31 on which the disc shaft product 20 is placed. When the surface of the support plate 31 is not flat, the three sets of height adjustment modules 32 can be finely adjusted until the top surface reaches the required high-precision horizontal reference state. This lays a solid and reliable reference foundation for the subsequent accurate positioning and detection of the workpiece.

[0051] After obtaining a support plate with a high-precision horizontal reference, the disc spindle product 20 is placed on the support plate 31. Using the detection execution component 10, the bottom end of the disc spindle product 20 can be leveled. This step ensures that the installation posture of the disc spindle product 20 on the support plate 31 is consistent with the height of the reference plane of the support plate 31, effectively eliminating the initial error caused by the uneven bottom surface or installation tilt of the disc spindle product 20.

[0052] The composite guide rail structure design greatly expands the coverage of the detection points. At the same time, combined with the height adjustment module 32 to pre-level the disc shaft product 20, the dial indicator can be flexibly and accurately positioned to the test point of the disc shaft product 20, so as to achieve high-precision measurement of the runout of the top of the disc shaft product 20.

[0053] Specifically, the height adjustment module 32 includes an adjustment plate 321, an adjustment sleeve 323 is fixedly disposed on the adjustment plate 321, an adjustment screw 324 is threadedly connected to the adjustment sleeve 323, and an installation rod 326 is disposed on the adjustment screw 324, the installation rod 326 being connected to the support plate 31.

[0054] In this embodiment, by adjusting the threaded engagement between the adjusting screw 324 and the adjusting sleeve 323, the adjusting screw 324 is rotated, causing it to displace in the vertical direction, which in turn drives the mounting rod 326 to adjust the height of the support plate 31. This structure provides micron-level adjustment accuracy, enabling the three sets of height adjustment modules 32 to work independently and collaboratively to compensate for the unevenness of the support plate 31 surface, ensuring that the top of the support plate 31 is horizontal, thereby eliminating tilt errors during the installation of the disc shaft product 20 and improving the measurement accuracy of runout detection.

[0055] Specifically, the standard turntable 41 has six sets of fixed T-slots 411 arranged in a circular array;

[0056] The adjustment plate 321 is provided with a fixing plate 322, the fixing plate 322 is provided with a fixing through groove 3221, the fixing T-slot 411 is provided with a fixing bolt, and the fixing bolt is engaged in the fixing through groove 3221. The outer wall of the fixing bolt is threaded with a fixing nut.

[0057] In this embodiment, the fixing bolt is snapped into the fixing T-slot 411 and can slide freely within the fixing T-slot 411. Combined with the open design of the fixing through slot 3221, the adjusting plate 321 can be continuously and steplessly adjusted along the long side of the fixing T-slot 411, so that the support plate 31 can perform a quick leveling process, significantly improving the versatility of the tooling.

[0058] Of course, after the fixing bolt passes through the fixing slot 3221, the fixing nut with threaded sleeve applies axial locking force, so that the fixing plate 322 is tightly attached to the surface of the standard turntable 41. This rigid connection method effectively suppresses vibration and micro-displacement during the detection process, ensures the reference stability of the leveling and positioning component 30, and thus improves the reliability of the runout detection data.

[0059] Specifically, three sets of support grooves 314 are evenly provided on the support plate 31, and support through grooves 315 are provided in the support grooves 314;

[0060] The mounting rod 326 is provided with a mounting part 328, which is slidably disposed in the support groove 314. The mounting rod 326 is slidably disposed in the support through groove 315. The outer wall of the mounting rod 326 is threadedly connected with a mounting nut 327, which contacts the bottom end of the support plate 31, so that the mounting rod 326 is fixed in the support through groove 315.

[0061] In this embodiment, the mounting nut 327 is threaded onto the outer wall of the mounting rod 326 and in close contact with the bottom end of the support plate 31. An axial locking force is applied by tightening, resulting in a bidirectional rigid fixation between the mounting part 328 and the bottom surface of the support groove 314, and between the mounting nut 327 and the bottom surface of the support plate 31. This structure quickly establishes a stable connection after releasing the degrees of freedom, effectively suppressing vibration transmission during the testing process and ensuring that the support plate 31 maintains the stability of the reference plane when carrying the disc shaft product 20.

[0062] Of course, when the adjusting plate 321 can be continuously and steplessly adjusted along the long side of the fixed T-slot 411, the mounting part 328 slides and adjusts accordingly in the support groove 314.

[0063] Specifically, a ball 3241 is fixedly provided on the adjusting screw 324, and a spherical groove 3261 is provided at the bottom end of the mounting rod 326. The spherical groove 3261 is adapted to the ball 3241, and the ball 3241 is disposed in the spherical groove 3261.

[0064] The adjusting screw 324 is fixedly sleeved with an adjusting nut 325 on its outer wall.

[0065] In this embodiment, the spherical adaptive fit between the sphere 3241 and the spherical groove 3261 forms a three-dimensional angular degree of freedom, allowing the mounting rod 326 to undergo slight deflection with height changes during the leveling process of the support plate 31. This eliminates the lateral constraint force caused by traditional rigid connections, avoids deformation of the support plate 31 due to uneven force, and ensures the smoothness and accuracy of the leveling action.

[0066] Specifically, the disc shaft product 20 has a connecting hole 21;

[0067] The support plate 31 has a support platform 311 at its center. The support platform 311 is provided with a threaded support bolt 312. The outer wall of the support bolt 312 is fitted with a support washer 313. The support bolt 312 is located in the connection hole 21, so that the support washer 313 contacts the disc shaft product 20 and presses the disc shaft product 20 onto the support platform 311.

[0068] In this embodiment, the support bolt 312 passes through the connecting hole 21 of the disc shaft product 20 and is threaded to the support platform 311, so that the central axis of the disc shaft product 20 is forced to be coaxial with the leveling reference surface of the support plate 31. The support shim 313 disperses the bolt clamping force, eliminates local stress concentration, and avoids the precision mating surfaces of the disc shaft product 20, such as the end face and journal, from being affected by clamping deformation, thus affecting the runout detection accuracy.

[0069] Specifically, a vertical guide plate 121 is provided on the vertical guide rail 12, and the vertical slider 123 is slidably disposed on the vertical guide plate 121;

[0070] The vertical slider 123 is provided with a threaded vertical positioning bolt 122, which contacts the vertical guide plate 121, so that the vertical slider 123 is positioned on the vertical guide rail 12.

[0071] In this embodiment, when the vertical positioning bolt 122 is tightened, it generates a normal frictional force with the surface of the vertical guide plate 121 to lock it, thereby fixing the vertical slider 123 instantly. This structure avoids the rebound error caused by the use of elastic clamps and meets the requirements for precision runout detection.

[0072] Specifically, a transverse guide plate 131 is provided on the transverse guide rail 13, and the transverse slider 132 is slidably disposed on the transverse guide plate 131;

[0073] The transverse slider 132 is provided with a threaded transverse positioning bolt 133, which contacts the transverse guide plate 131, so that the transverse slider 132 is positioned on the transverse guide rail 13.

[0074] In this embodiment, when the transverse positioning bolt 133 is tightened, it generates surface contact friction with the surface of the transverse guide plate 131 to lock it in place, thereby fixing the transverse slider 132 instantly. This structure suppresses the vibration displacement of the dial indicator caused by the rotation of the workpiece during the instant of detection, ensuring the reliability of the data from high-speed vibration detection.

[0075] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
