Description

Technical Field

[0001] The utility model relates to the technical field of grinding fixtures, in particular to a grinding fixture for a deep hole drilling micro tool. Background Art

[0002] A deep hole drill is a drill specifically designed for deep holes. It can be categorized as either external or internal chip removal. In machining, a hole with a depth-to-diameter ratio greater than 6 is generally considered a deep hole. Deep hole drilling is difficult to dissipate heat and remove chips, and the slender drill rod has poor rigidity, making it prone to bending and vibration. With the rapid development of science and technology and industrial production, the application of tiny deep holes is becoming increasingly widespread, resulting in an increasing number of parts with tiny deep holes, such as instrument components for aerospace inertial gyroscopes, fuel injectors for aircraft, automotive, and marine engines, film cooling holes for turbine engine blades, computer print heads, and printed circuit boards.

[0003] The existing public patent (publication number CN216228356U) discloses a deep hole drilling micro-tool grinding fixture, which can quickly fix, clamp and disassemble the fixed end of the tool through a fixed plate, a limit plate and a clamping unit. The adjustment unit and the fixed rod can drive the fixed plate and the tool fixed and clamped by the clamping unit in the fixed plate to adjust the position, thereby making this deep hole drilling micro-tool grinding fixture easy to use and applicable. The positioning hole can be used to quickly position the deep hole drilling micro-tool grinding fixture when it is placed. The installation hole can be used to quickly fix, install and disassemble the deep hole drilling micro-tool grinding fixture. The buffer pad can reduce the friction between the splint and the tool when the splint clamps the tool.

[0004] However, there are some problems with the existing clamps during use: 1. The current clamping structure and the lifting assembly are engaged and fixed by multiple bolts. When the clamping assembly needs to be maintained, multiple bolts need to be engaged and disassembled in sequence. After maintenance, multiple bolts need to be engaged and installed again, which is a cumbersome operation process; 2. The existing clamps require the spacing of each clamp to be adjusted individually in order to position the drill bit tool, which affects the clamping efficiency. Utility Model Content
