Description

Technical Field

[0001] This utility model relates to the field of grinding wheel inspection technology, specifically to a grinding wheel groove-type tooling for cutting carbon sheets. Background Technology

[0002] Chamfered grinding wheels are a type of superhard abrasive forming grinding wheels. Compared to conventional forming grinding wheels and tool grinding wheels, chamfered grinding wheels have a larger wheel shape and a relatively simple groove shape.

[0003] The inspection of chamfering grinding wheels typically employs two methods: offline and online inspection. Offline inspection involves grinding a graphite plate (or other softer replica plate, such as Q235 or aluminum alloy) onto the grinding wheel, replicating the wheel's profile onto the replica plate, and then inspecting the profile of the replica plate. Online inspection involves observing the grinding wheel's profile directly through visual or laser ranging methods while the grinding wheel rotates at high speed. The relevant dimensions of the profile are obtained through processes such as outer edge detection, fitting, and comparison. A common chamfering grinding wheel profile is a deep V-shaped arc groove. With this groove shape, offline inspection inevitably causes extrusion deformation of the replica plate due to batch processing. The replicated profile, obtained under this deformation, cannot accurately reflect the grinding wheel's profile, directly affecting the inspection accuracy. This ultimately leads to material waste in the batch inspection process, resulting in a high rate of non-conformance or false detection. However, online inspection methods are affected by factors such as light diffraction at the edge of the grinding wheel, focal length error, and fitting error, resulting in low inspection accuracy. Therefore, they cannot be used as the final reliable inspection result for chamfered grinding wheels. Utility Model Content

Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] like Figure 1 and Figure 2 As shown, this utility model provides a grinding wheel groove type carbon sheet cutting fixture. The grinding wheel groove type carbon sheet cutting fixture includes a base 1, the base 1 has a "U" shaped structure, the base 1 has a groove 12, and the two ends of the side wall of the base 1 have through holes 11 respectively. The bottom of the "U" shaped structure of the base 1 is fixed by clamping on the tool post of the lathe to keep it horizontal.

[0027] like Figure 1 and Figure 2 As shown, the grinding wheel groove cutting carbon sheet tooling includes a positioning shaft 2. One end of the positioning shaft 2 is respectively set in the through holes 11 on both sides of the base 1. Specifically, the positioning shaft 2 is inserted into the through hole 11. The positioning shaft 2 has a tapered structure and a tip 22. A first screw 21 is provided on the positioning shaft 2 and passes through the base 1 for fixing and clamping.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, the grinding wheel groove-type carbon sheet cutting fixture includes a roller 3, which is located in the groove 12 of the "U"-shaped structure of the base 1. The roller 3 has a connecting hole 31 on the side near the through hole 11, and the tip 22 of the positioning shaft 2 is inserted into the connecting hole 31. The other end of the positioning shaft 2 is located in the roller 3, and the roller 3 is connected to the base 1 through the positioning shaft 2. The roller 3 is provided with a positioning slot 32, in which a carbon sheet 5 can be inserted. The roller 3 is provided with an insertion hole 33, in which a rocker arm 34 can be inserted for manually swinging the fixture. The roller 3 is rotatable.

[0029] like Figure 1 and Figure 4 As shown, the grinding wheel groove type carbon sheet cutting fixture includes a clamping member 4, which is located in the positioning groove 32. The clamping member 4 is provided with a threaded hole 41, and a second screw 42 can be screwed into the threaded hole 41 to fix the clamping member 4. The clamping member 4 and the positioning groove 32 cooperate to clamp the carbon sheet 5. The structural dimensions of the clamping member 4 and the positioning groove 32 are matched.

[0030] The working principle of this utility model:

[0031] (1) Clean all the workpieces of the entire fixture with alcohol. Place the roller 3 in the middle of the base 1, and then insert the positioning shaft 2 into the through holes 11 at both ends of the roller 3. Insert the first screw 21 into the positioning shaft 2 and pass it through the base 1 for fixing and clamping. Use the tip 22 to press against the through holes 11 at both ends of the roller 3 to ensure that the distance between the two ends of the roller 3 and the two ends of the base 1 is consistent.

[0032] (2) Place the carbon sheet 5 in the positioning slot 32 of the roller 3, with the usable part of the carbon sheet 5 facing outwards. The bottom of the carbon sheet 5 should abut against the bottom of the positioning slot 32 of the roller 3, ensuring a tight fit. Then, place the clamping member 4 into the positioning slot 32, insert the second screw 42 into the threaded hole 41 of the clamping member 4, and tighten the second screw 42 to secure the roller 3 and the clamping member 4, ensuring a tight fit and guaranteeing that the carbon sheet 5 remains stable during use. The overall tooling assembly is now complete.

[0033] (3) Place the bottom of base 1 onto the lathe cutting tool. The tool post must be cleaned first. Tighten the tool post to clamp the base 1, ensuring that the bottom of base 1 is completely in contact with the bottom of the tool post. Mount the grinding wheel to be tested onto the lathe spindle. Move the tool post and fixture to align the carbon sheet 5 with the groove of the grinding wheel. Start the lathe to rotate the grinding wheel, bringing the carbon sheet 5 close to the grinding wheel. Rotate the roller 3 to make the carbon sheet 5 swing up and down, slowly increasing the forward distance of the carbon sheet 5. Repeat the above steps until the carbon sheet 5 fully reflects the groove of the grinding wheel. Then stop and remove the carbon sheet 5 for testing.
