[0024] The utility model will be further described in detail below in combination with examples.

[0025] The utility model provides a specific embodiment of the multi-segment support for camshaft slot detection:

[0026] Please refer to Figures 1-5 , the multi-segment support for camshaft slot detection, including magnetic base 1, magnetic base 1 is connected with support 6 through a plurality of supporting rods;Specifically, the first supporting rod 2 is fixedly connected on one side of the magnetic base 1, the first supporting rod 2 is connected with the second supporting rod 3, the second supporting rod 3 is connected with the third supporting rod 4, and the third supporting rod 4 is fixedly connected with the support 6 at the end.

[0027] In this embodiment, the first supporting rod 2 and the third supporting rod 4 are vertical rods, and the second supporting rod 3 is a horizontal rod. The second supporting rod 3 is connected with the first supporting rod 2 and the second supporting rod 3 is connected with the third supporting rod 4 through fasteners 5, and the fasteners 5 are prior art, and the specific structure of this embodiment will not be described again, such as the fastener in the patent CN210426308U of the dial indicator support convenient to read value.

[0028] Specifically, in this embodiment, one end of the second support rod 3 is fixedly connected to a fastener 5. This fastener 5 is sleeved on the outside of the first support rod 2 and can move vertically along the first support rod 2, or it can be clamped and positioned on the outside of the first support rod 2. The upper end of the third support rod 4 is fixedly connected to a fastener 5. This fastener 5 is sleeved on the outside of the second support rod 3 and can move laterally along the second support rod 3, or it can be clamped and positioned on the outside of the second support rod 3. The outer sides of the first support rod 2 and the second support rod 3 are provided with scales.

[0029] The support 6 is vertically rotatably connected to the dial gauge 17 clamping seat 7. The support 6 is fan-shaped plate. The dial gauge 7 is existing technology, and its specific structure will not be described in this embodiment. For example, the dial gauge 7 in the simple measuring bracket of a lever dial gauge published by patent CN215722203U.

[0030] The watch holder 7 is connected to a handle 8; the watch holder 7 can be driven to rotate by hand using the handle 8. The watch holder 7 is connected to a rotating column 16, which is a cylindrical structure with an I-shaped cross-section. The support 6 is provided with a through hole that rotates with the middle part of the rotating column 16; the middle part of the rotating column 16 rotates within the through hole of the support 6.

[0031] The support 6 is provided with an arc-shaped hole 9 corresponding to the rotation center of the dial holder 7. The support 6 is provided with an arc-shaped rack 10, which is located on one side wall of the arc-shaped hole 9. A retaining strip 11 that cooperates with the arc-shaped rack 10 is slidably connected to the handle 8. The retaining strip 11 slides along the radial direction of the arc-shaped hole 9, and one end of the retaining strip 11 extends into the arc-shaped hole 9.

[0032] The handle 8 has a strip-shaped hole 12; the locking strip 11 passes laterally through the strip-shaped hole 12, and the pull rod 13 slides through the handle 8. In this embodiment, the handle 8 has a light hole for the pull rod 13 to pass through. The inner end of the pull rod 13 extends into the strip-shaped hole 12 and is connected to the locking strip 11, and the outer end of the pull rod 13 extends to the outer side of the end of the handle 8 and is connected to a pull ring 15.

[0033] A helical spring 14 is sleeved on the outside of the pull rod 13 inside the strip hole 12. The two ends of the helical spring 14 are in contact with the inner wall of the strip hole 12 and the retaining strip 11, respectively. When there is no external force, the helical spring 14 makes the retaining strip 11 mesh with the arc-shaped rack 10.

[0034] Testing process: Position the camshaft on the testing table with its end arc-shaped groove facing upwards;

[0035] Fix the position of the magnetic base 1, adjust the positions of the second support rod 3 and the third support rod 4 so that the rotation center of the gauge holder 7 corresponds to the center of the arc groove of the camshaft, and then use the fastener 5 to position the support rod (this process requires external measuring equipment calibration. After calibration until the rotation center of the gauge holder 7 corresponds to the center of the arc groove, the positions of the support rod and the magnetic base 1 no longer change, and the grooving inspection of each processed camshaft can be carried out in batches).

[0036] Place the dial indicator 17, as shown. Figure 1 As shown, the dial indicator 17 is brought into contact with the bottom of the groove in the middle of the slot, and the pointer is rotated to a certain value. Then, the dial indicator 17 is positioned using the gauge holder 7.

[0037] Pull the ring 15 to compress the coil spring 14 via the lever 13, and separate the locking strip 11 from the arc-shaped rack 10; then turn the handle 8 to both sides and observe the fluctuation of the dial indicator 17 pointer to detect the arc surface of the groove bottom.

[0038] When the pull ring 15 is released, the coil spring 14 engages and positions the locking strip 11 with the arc-shaped rack 10, allowing the dial indicator 17 to be positioned in multiple locations and its displayed value to be recorded. As shown in the attached diagram, when the pull ring 15 is not pulled, the gauge holder 7 and the dial indicator 17 cannot rotate, and this bracket functions the same as a traditional bracket.
