High-precision resistance trimming machine capable of regulating resistance of current divider

Abstract

The invention discloses a high-precision resistance trimming machine capable of regulating resistance of a current divider. A first operating table, a second operating table, a resistance trimming machine body and a drill bit are matched for use, so that efficiency and precision of the resistance trimming machine can be effectively improved; a resistance trimming column, a drill column, the drillbit and a supporting base are matched for use, so that influences on the functions of apparatuses by a laser resistance trimming machine can be eliminated; the drill column drives the drill bit to rotate at a high speed; a first hydraulic cylinder makes a second hydraulic column move downwards in a first hydraulic column; and the second hydraulic column drives the resistance trimming column to move downwards such that the drill bit moves downwards until the drill bit is in contact with the current divider body and drills the current divider body. The high-precision resistance trimming machinecan effectively solve the problem that resistance trimming efficiency and precision is not good and the problem that influences are caused on the functions of the apparatuses in a resistance trimmingprocess.

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a high-precision resistance adjusting machine for adjusting the resistance value of a shunt. Background technique [0002] The resistance adjustment machine is a device that can adjust the resistance of the device. It can overcome the defects of low efficiency and low accuracy caused by manual adjustment of the resistance of the device in the past, and can effectively improve the efficiency and accuracy of the adjustment of the resistance of the device. [0003] The laser resistance trimming machine uses a very fine laser beam to hit the thick and thin film resistors, and realizes the cutting of the thick and thin film circuits by vaporizing and evaporating the resistor body. Changing the geometry of thick and thin film resistors changes the resistance value of the resistor. As the laser cutting process progresses, the real-time measurement circuit monitors the chan...

Problems solved by technology

[0007] How to solve the problem of affecting the function of the device during the resistance adjustment process; through the combined use of the set resistance adjustment column, drill string, drill bit and support seat, the influence of the laser resistance adjustment machine on the function of the device can be eliminated; The resistance column rotates at high speed, and the drill string drives the drill bit to rotate at high speed. The second hydraulic column moves downward in the first hydraulic column through the first hydraulic cylinder, and the second hydraulic column drives the resistance adjustment column to move downward, so that the drill bit moves downward. , until the drill bit is in contact with the diverter body and the diverter body is drilled and cut; after drilling and cutting, the second hydraulic column is used to move up in the first hydraulic column, so that the resistance adjustment column drives the drill string and the drill bit to move up, and completes the splitter. The drilling and cutting of the main body and the adjustment of the resistance value, using the mechanical drilling and cutting of the drill bit, will not affect the function of the shunt under the condition of ensuring the precise adjustment of the resistance value, which solves the problem of the device during the resistance adjustment process of the existing scheme Problems affecting functionality
