Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing, specifically to a bell-shaped shell groove dynamic deformation testing instrument. Background Technology

[0002] For constant velocity universal joints at the fixed end, the clearance between the bell-shaped shell groove and the steel ball, star-shaped sleeve, and cage is crucial; otherwise, jamming at any stage will occur, leading to product defects. The cross-section of the bell-shaped shell groove is also critical; the smooth sliding of the steel ball within the groove depends on the fit between the steel ball and the groove contact surface. Currently, the acceptance test for bell-shaped shell grooves involves wire-cutting a groove contour template, comparing the template against the groove, and visually inspecting whether the gap between the template and the groove remains consistent. However, due to differences in individual methods and visual inspection, the test results will vary, and there is no single, universally accepted standard for acceptance. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings. A bell-shaped shell channel dynamic deformation detector includes a support 1, which includes a top plate 2 and a middle plate 3, and a through groove 21 extending through the top plate; a positioning assembly including a positioning plate 41 and a movable plate 42, the movable plate being movably mounted on the top plate, the positioning plate and the movable plate being used to contact the channel of the inner wall of the bell-shaped shell, a portion of the positioning plate passing through the through groove, and a portion of the movable plate passing through the through groove; a detection assembly including a first slide 51 and a second slide 52, the first slide and the second slide being movably mounted on the middle plate; a portion of the first slide passing through the through groove is provided with a first probe 511, and a portion of the second slide passing through the through groove is provided with at least two second probes 521, the two second probes being correspondingly located on both sides of the first probe; and a measuring device 6, mounted on the first slide, with one end facing the second slide.

[0020] When using it, first place the confirmed qualified parts (or standard parts, which can integrate the grooves of multiple different models of universal joints into one piece for easy use) on the top plate. At this time, the positioning plate will hook into a groove, and the movable plate will hook into the groove opposite the first groove at 180°. Push the second slide to drive the first slide to the bottom. The first probe will contact the bottom of the groove, and the second probe will contact the inner wall of the groove. At this time, return the dial indicator to 0. Then, remove the standard part and place the workpiece to be tested on the top plate with its opening facing the slot. Similarly, place the positioning plate in one groove, hook the movable plate into the opposite groove, and push the second slide to move the first slide to the bottom. The first probe will contact the bottom of the groove, and the second probe will contact the inner wall of the groove. At this point, if the dial indicator does not read 0, the part is defective. This improves testing efficiency and ensures product inspection quality.

[0021] It should be noted that there are two second probes (set in parallel), symmetrically arranged on both sides of the first probe. The center lines of the positioning plate and the movable plate coincide, and the center lines of the first slide and the second slide are also on a straight line. The first probe is installed in the center of the first slide, and the center line of the first slide coincides with the center line of the positioning plate.

[0022] In this embodiment, as shown in the figure, the measuring instrument is a dial indicator. It is more convenient to use, and its probe at the tail end is used to contact the second slide.

[0023] In this embodiment, as shown in the figure, the tail end of the first probe has a spherical structure, making it easier to make proper contact.

[0024] In this embodiment, as shown in the figure, the top plate is provided with a mounting groove 210, the mounting groove is connected to the through groove, the positioning plate is fixedly installed at one end of the mounting groove, and the movable plate is slidably engaged with the inner wall of the mounting groove.

[0025] In this embodiment, as shown in the figure, the tail end of the movable plate extending from the mounting groove is provided with a protruding ring and a circumferentially arranged spring 421. One end of the spring contacts the protruding ring, and the other end contacts the outer wall of the top plate. This serves as an automatic clamping mechanism; once the workpiece is placed in, releasing the handle will allow it to be pressed into place by the spring.

[0026] In this embodiment, as shown in the figure, a slide rail 31 is provided on the intermediate plate, and the first slide block and the second slide block are mounted on the slide rail. This facilitates movement.

[0027] In this embodiment, as shown in the figure, the second slide is provided with a push rod 32 for manual operation. This facilitates manual operation.

[0028] In this embodiment, as shown in the figure, a second spring 515 is provided on the first slide block, with one end of the second spring used for contact with the second slide block. Through the contact of the second spring, the contact area is large, and after reaching its position, it will retract until the second slide block contacts the dial indicator. Specifically, it can be installed on the outer side of the tail end of the dial indicator.

[0029] In this embodiment, as shown in the figure, a wedge block 33 is provided at the bottom of the intermediate plate, and the bracket also includes a base plate 60. A base 61 is provided on the base plate, and a second wedge block 62 is provided on the base for sliding engagement. The second wedge block engages with the inclined surface of the wedge block, and an adjusting rod 63 with thread engagement is provided on the second wedge block. The height of the intermediate plate can be adjusted to accommodate different center moments, and a scale 9 is provided on the bracket to indicate the specific adjustment distance.
