These parts require sub-micron level shape accuracy, nanometer level surface roughness and extremely small subsurface damage. Some key microstructures in the parts need to be processed by ultra-precision milling to meet the requirements of precision and surface quality.

[0003] For the machining of concave hemispherical surface of complex parts with extremely small caliber, special tools with small size need to be used in combination with corresponding processing methods to meet the requirements. In the process of machining hard and brittle materials, diamond is the best tool material, and the forming contour accuracy and forming requirements of concave hemispherical surface are extremely high, so a diamond tool for concave spherical surface microstructure forming is needed.

[0004] However, most of the existing diamond tools for concave spherical surface microstructure forming have the problems that the tool head and the tool shank are welded together during use, and the damaged tool head cannot be easily disassembled and replaced, so that the tool cannot meet more use requirements and the practicality is not strong enough. Therefore, a diamond tool for concave spherical surface microstructure forming is proposed to solve the above problems. INVENTION CONTENTS

[0005] In order to make up for the shortcomings of the prior art, solve the problem that most of the existing diamond tools for concave spherical surface microstructure forming have the problems that the tool head and the tool shank are welded together during use, and the damaged tool head cannot be easily disassembled and replaced, so that the tool cannot meet more use requirements and the practicality is not strong enough, the utility model provides a diamond tool for concave spherical surface microstructure forming.

[0006] The technical scheme adopted by the utility model to solve its technical problems is: the utility model discloses a diamond tool for concave spherical surface microstructure forming, which comprises a tool shank, and the right side of the tool shank is provided with a diamond tool head.

[0007] The tool shank is fixedly installed with the diamond tool head through a mounting assembly, the mounting assembly comprises a threaded rod, the threaded rod is installed with the tool shank, a threaded hole is formed in the left side of the diamond tool head, the threaded rod is in threaded connection with the threaded hole, an adjusting assembly is arranged in the tool shank, and the adjusting assembly is installed with the threaded rod.

[0009] Preferably, the limiting assembly comprises a limiting groove formed in the inside of the telescopic plate, a front-rear through sliding groove is formed at the left side of the limiting groove, a clamping assembly is arranged in the sliding groove, the limiting groove extends to the right side of the threaded rod at the right side, the limiting groove is communicated with the threaded hole at the inside, a limiting ring is fixedly connected in the limiting groove, a sliding ring is slidably connected in the limiting groove, a spring No.

[0010] Preferably, the clamping assembly comprises a fixed ring fixedly connected in the front and rear of the sliding groove, a sliding block is slidably connected in the front and rear of the sliding groove, a spring No.

[0011] Preferably, the outer surface of the limiting block is arc-shaped, and the outer surface of the limiting block is matched with the outer surface of the connecting block.

[0012] Preferably, the right side of the tool shank is matched with the left side of the diamond tool bit, and the left end of the threaded rod is matched with the right side of the tool shank.

[0013] Preferably, the outer surface of the clamping block is arc-shaped.

[0014] Preferably, the outer surface of the tool shank is provided with anti-skid lines.

[0015] The utility model discloses the beneficial effect lies in:

[0016] 1. The utility model discloses a threaded connection of threaded rod and threaded hole can make the tool shank and diamond tool bit between convenient disassembly and installation, and convenient disassembly replacement after diamond tool bit is damaged, thereby make the cutting tool can satisfy more use demand, and practicality is stronger.

[0017] 2. This utility model uses a locking block to securely engage the telescopic plate within the slot, and a limiting block further secures the locking block within the slot. When the telescopic plate needs adjustment to extend the tool holder for greater flexibility, rotating the tool holder causes the threaded rod to move within the threaded hole. As the threaded rod rotates, the pressing block gradually disengages, causing the pressing block, limiting rod, and limiting block to move. The limiting block then disengages from the connecting block, and further movement of the tool holder allows the tool to extend. The sliding of the handle on the outer surface of the telescopic plate allows the handle to extend. As the handle slides, the locking block inside the slot is compressed. The locking block retracts by compressing the slider and spring. When the locking block aligns with another slot, the rebound force of the spring causes the slider and locking block to move and engage inside the slot, thus keeping the handle stable after sliding. Therefore, the sliding connection between the handle and the telescopic plate allows the handle to be adjusted as a whole, and the telescopic plate further increases the length of the handle, thus meeting the need for the handle to extend during use.
