Description

Technical Field

[0001] The utility model relates to the technical field of protective devices, in particular to a PCD tool protective device. Background Art

[0002] PCD tools, also called polycrystalline diamond tools, can withstand higher linear speeds, which can significantly improve processing efficiency. Moreover, they have high hardness and strong wear resistance, so they are also widely used. For example, in the patent number "CN212352338U" and the patent name "a tool protective cover", when the upper baffle and the lower baffle are both installed on the dust cover, the groove at the bottom of the upper baffle is opposite to the groove at the top of the lower baffle, and a gap is formed. The workpiece can be inserted into the dust cover through the gap. When it is necessary to adapt to tools with different heights of teeth, it is only necessary to make the second fixing holes of appropriate heights on the upper baffle and the lower baffle correspond to the first fixing holes on the dust cover. By adjusting the installation position of the upper baffle and the lower baffle, not only can the utility model be installed on tools with various heights of teeth, thereby improving the versatility of the utility model, but also the air inlet area at the front end of the dust cover can be reduced to increase the dust collection effect.

[0034] After the tool body 2 is processed by the mounting rod 1, it is only necessary to pull the clamping rod 4 outward, so that the inner end of the clamping rod 4 is separated from the clamping groove 6, thereby releasing the limit of the sliding sleeve 3, so that the sliding sleeve 3 can slide downward, and the sliding sleeve 3 drives the connecting rod 7 to slide downward together, and the rotation connection formed between the lower end of the connecting rod 7 and the protective plate 8 is formed, so that the protective plate 8 is rotated downward with the rotation connection formed between it and the mounting rod 1 as the center, so that the two sets of protective plates 8 are closed, and the protective plate 8 drives the fitting groove 9 to fit with the tool body 2, thereby protecting the tool body 2, and no other tools are needed for assistance, the operation process is simple and convenient, thereby greatly improving the efficiency, and the elastic force of the return spring 5 can make the clamping rod 4 when it is not under force, its inner end can always be engaged with the clamping groove 6, thereby improving the practicality, and when the tool body 2 is not used, it can be protected, and there is no need to disassemble and reinstall the tool body 2, which greatly saves time;

[0035] Embodiment 2: Different from Embodiment 1, this embodiment facilitates the maintenance of the tool body 2 without the need for manual application of lubricating oil.
