Precise adjusting mechanism capable of being automatically adjusted manually

Abstract

The invention relates to the technical field of adjusting mechanisms, in particular to a precise adjusting mechanism capable of being automatically adjusted manually. The mechanism is characterized inthat a grinding wheel, a motor, a motor seat, a guide block, a sliding rail, a fixing block, a base, a cam shaft, a stepping motor, a top block, a fixing frame and a separation clamp are arranged onthe mechanism, wherein the motor is arranged on the motor base, the grinding wheel is connected to the output end of the motor, the sliding rail is arranged on the guide block, and the motor base is slidably connected to the sliding rail; the base is fixed on the fixed block, and the fixing block is fixedly connected with the guide block; the cam shaft is erected on the base, and the cam shaft isconnected with the output end of the stepping motor, and the fixing frame is arranged on the fixing block in a covering mode; and the separating clamp penetrates through the fixing frame to be in contact with one end of the top block, and the other end of the top block is in contact with the cam shaft. According to the precise adjusting mechanism capable of being automatically adjusted manually,the intelligent and high-precision in the PCB micro-drilling machining process can be realized, the production qualification rate is improved, and the stability of the PCB micro-drilling machining process is ensured.

Description

technical field [0001] The invention relates to the technical field of adjustment mechanisms, in particular to a precision adjustment mechanism capable of manual and automatic adjustment. Background technique [0002] PCB, the Chinese name is printed circuit board, is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. [0003] In the production process of a formed PCB, various micro-drills of different specifications are required for drilling, and the processing accuracy of the micro-drill is closely related to the processing requirements of the PCB. Due to some unavoidable and uncontrollable external factors in the process of micro-drilling, after the completion of a micro-drilling process, one side of the micro-drilling surface may be too large, one side is too small, or the length of the cutting surface may be different. Situation, in order to better improve the qualified rate of suc...

Problems solved by technology

Due to some unavoidable and uncontrollable external factors in the process of micro-drilling, after the completion of a micro-drilling process, one side of the micro-drilling surface may be too large, one side is too small, or the length of the cutting surface may be different. situation, in order to better improve the pass rate of such defective products, it is necessary for us to provide an adjustment device to solve the above problems

However, the traditional adjustment methods are controlled by piezoelectric ceramics or ball screws. These two adjustment methods have defects such as low reliability, low efficiency and low precision.
