Example Embodiment

[0027] Example 1

[0028] Such as Figure 1-2 As shown, a device for correcting the pre-tightening force between the striker and the nozzle, the device for correcting the pre-tightening force between the striker and the nozzle, is used for a piezoelectric injection valve, and the piezoelectric injection valve includes a valve body 1, The piezoelectric actuator 2 is arranged in the valve body 1, the striker 4 is slidably mounted on the valve body 1, and the nozzle 5 is located below the valve body 1. The piezoelectric actuator 2 drives the striker 4 through the lever 3 to amplify the driving force Feed to the nozzle 5. The device includes:

[0029] The first adjusting mechanism has a pre-tensioning member 8 and an upper adjusting block 9 and a lower adjusting block 10 that cooperate with each other. The pre-tensioning member 8 is limited to the side of the upper adjusting block 9 and can push the upper adjusting block from the side 9. The lower adjusting block 10 drives the piezoe...

Abstract

The invention relates to the technical field of piezoelectric injection valves, in particular to a device for correcting pre-tightening force between a firing pin and a nozzle. The device comprises afirst adjusting mechanism and a second adjusting mechanism, wherein the first adjusting mechanism is provided with a pre-tightening piece and an upper adjusting block and a lower adjusting block whichare matched with each other; and the second adjusting mechanism is provided with an adjusting rod, and the bottom end of the adjusting rod abuts against the upper surface of the upper adjusting block. According to the device, the first adjusting mechanism is ingeniously utilized to roughly adjust the horizontal position of a lever so as to facilitate assembly of a piezoelectric actuator, the position of the lever is accurately adjusted in a follow-up manner by matching with the second adjusting mechanism, so that the pre-tightening force between the firing pin and the nozzle is adjusted, andthe problem that the piezoelectric actuator is too loose or too tight during adjustment can be avoided; and the nozzle at the current installation position can be adapted by driving the firing pin tomove after being mounted in the nozzle, the mounting position of the nozzle does not need to be accurately mastered, the assembly difficulty of the nozzle is greatly reduced, and the maintenance efficiency of the nozzle is improved.

Description

technical field [0001] The present invention relates to the technical field of piezoelectric injection valves, in particular to a device for correcting the pre-tightening force between the striker and the nozzle. device for piezoelectric injection valves. Background technique [0002] With the rapid development of the electronics industry, the requirements for electronic packaging are getting higher and higher. For the high-demand electronic packaging technology, non-contact injection valves are more and more widely used in the field of electronic packaging due to their high efficiency and high precision. The piezoelectric stack with high response speed and high precision is the core driving component of the non-contact piezoelectric injection valve, and it is also widely used in non-contact injection valves; [0003] As we all know, the main structure of a piezoelectric valve is composed of a valve body, a piezoelectric actuator installed in the valve body, an amplifier, a...
