Description

Technical Field

[0001] This utility model relates to the field of camshaft machining technology, specifically to an automatic grinding wheel dressing mechanism for camshaft machining. Background Technology

[0002] When grinding a camshaft, the camshaft is placed in a clamping mechanism, which drives the workpiece to rotate. The feed motion of the grinding mechanism is linked with the rotation motion of the workpiece to produce a camshaft that meets the requirements.

[0003] A search revealed a Chinese patent publication number: CN220516372U, which discloses a camshaft machining and grinding machine, including a base, a worktable, and a grinding assembly. The grinding assembly includes a mounting base, a transmission screw, a transmission slider, a stabilizing sleeve, a connecting rod, a crossbeam, a machining component, and a power component. The base supports the worktable, and a working groove is provided on the worktable. A clamping mechanism is provided in the working groove.

[0004] Although the aforementioned patent allows for adjustable grinding height, the aforementioned device still has the following problems: during the use of the device, the grinding waste easily falls into the inside of the working groove, making it difficult to clean the waste inside the working groove. With long-term use, the accumulation of waste inside the working groove can affect the positioning and fixation of the camshaft, thereby reducing the processing quality of the camshaft. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content

[0012] Preferably, the output end of the first motor rotates through the interior of the workbench and extends into the interior of the cleaning rod, and the output end of the first motor is fixedly connected to one end of the first threaded rod via a coupling.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This automatic grinding wheel dressing mechanism for camshaft machining uses a moving frame that drives a support plate to rotate via a rotating frame and connecting rod. This allows the support plate to tilt and reset, enabling smoother cleaning of impurities. Simultaneously, a cleaning rod with a brush cleans the tilted support plate and removes waste residue from the top of the support plate. This facilitates the cleaning and collection of impurities inside the chamber, making the device more convenient to use and reducing the impact of impurities on the camshaft grinding process, thus ensuring smoother camshaft machining.

This allows the operator to more easily clean and collect the impurities inside the chamber 3 and makes it more convenient for the operator to use the device.

[0021] Working principle: For this type of automatic grinding wheel dressing mechanism used for camshaft machining, the camshaft is first clamped and fixed by the cylinder and other structures set inside the chamber 3. The grinding device can grind the camshaft. The operator starts the second motor 17, which drives the second threaded rod 18 to rotate in both directions. Under the restriction of the adjustment groove 13, the second threaded rod 18 drives the moving frame 14 to move back and forth. The moving frame 14 drives the support plate 11 to rotate through the rotating frame 15 and the connecting rod 16, thereby realizing the tilting and resetting of the support plate 11, so that the support plate 11 can be cleaned of impurities more smoothly. The operator starts the first motor 9, which drives the first threaded rod 8 to rotate. Under the constraint of the cleaning rod 7, the first threaded rod 8 drives the cleaning rod 7 to move back and forth. At the same time, the cleaning rod 7 can clean the inclined support plate 11 with a brush and remove the waste residue on the top of the support plate 11.
