Abstract

The invention provides an oil atomizer pull-out tooling, and belongs to the technical field of oil atomizers. The oil atomizer pull-out tooling comprises a pull-out tooling body. The pulling-out tooling body comprises a pull rod, a connecting block, a fixing block, two clamping jaws and a pulling hammer; a first through hole is formed in the fixing block; one side of each clamping jaw is connectedwith a connecting plate, the connecting plates are rotatably arranged in the first through hole; a second through hole is formed in the connecting block; the first through hole and the second throughhole are axially parallel; a first pull hole is formed in each clamping jaw; a first spring is arranged in the second through hole; the two ends of the first spring are hooked between the two clamping jaws through first pull holes; a screw is fixed to one end of the pull rod, and the surface of the pull rod is connected with the pulling hammer in a sliding mode; and the clamping jaws are pushed to be buckled through the first spring, then the pulling hammer is continuously slid to impact the screw, and an oil atomizer is rapidly and effectively pulled out through impact force.

Description

technical field [0001] The invention relates to the field of fuel injectors, in particular, to a tool for pulling out a fuel injector. Background technique [0002] The fuel injector is a precision device with very high machining accuracy, which requires a large dynamic flow range, strong anti-clogging and anti-pollution capabilities, and good atomization performance. The fuel injector receives the fuel injection pulse signal sent by the ECU to precisely control the fuel injection quantity. [0003] The fuel injector requires a special pull-out tool for disassembly and maintenance. The existing pull-off tools are relatively simple and inconvenient to use, making it difficult to quickly and effectively disassemble the fuel injector. Contents of the invention [0004] In order to make up for the above deficiencies, the present invention provides a pull-out tool for the fuel injector, which aims to improve the problems that the traditional pull-off tool is inconvenient to us...
