Embodiment Construction
[0015] The embodiment of the circuit breaker pressure cylinder assembly size detection tool of the present invention: as Figure 2-4 As shown, the tooling body is included, and the tooling body includes a support seat 30. The support seat 30 is a disc shape with a ring groove 310 on one end surface. The maximum diameter of the ring groove 310 is equal to the diameter of the right end of the large spout 103. When in use, the ring The groove bottom of the groove 310 is used as the positioning surface of the entire tooling to fit the rightmost end of the large spout 103, the groove wall of the ring groove 310 away from the center of the circle is used to fit the outer periphery of the big spout 103, and the central area surrounded by the ring groove 310 31 is provided with a mounting hole that runs through the support base 30 and extends along the axial direction. The center line of the mounting hole is located on one side of the center line of the support base 30. A measuring rod...

The invention provides a tool for detecting the assembly size of a circuit breaker pressure cylinder, comprising a tool body, a support seat on the tool body, a positioning surface on the support seat, and a measuring rod for extending into a large spout and passing through a small spout is rotatably assembled. The measuring rod is arranged perpendicular to the support base and is guided and slidably matched with the support base in the left-right direction. The rod is provided with an eccentric block, and the stop structure limits that when the measuring rod is guided and moved relative to the support seat, the farthest distance between the front end surface of the eccentric block and the positioning surface is the upper limit of the standard size, and the closest distance is the lower limit of the standard size. The scale marks include Standard size upper limit and standard size lower limit. The detection tooling of the invention has a simple structure, does not need to set specific size readings, is convenient and quick to operate, and can fully meet the precise detection of the assembly size of the circuit breaker pressure cylinder.
Description
technical field [0001] The invention relates to a tool for detecting assembly dimensions of a circuit breaker cylinder. Background technique [0002] With the rapid development of high-voltage power transmission and transformation projects, high-voltage circuit breakers have been widely used. The compressed air cylinder is the core component of the high voltage circuit breaker. It mainly plays the role of compressed air and arc extinguishing during the opening and closing process of the circuit breaker. The precise assembly of the compressed air cylinder is very important for its good working and running state. The schematic diagram of the assembly of the circuit breaker pressure cylinder is as follows: figure 1 As shown, the assembly size of the pressure cylinder requires that the distance between the right end of the large nozzle and the right end face of the moving arc contact be L±d, L is the error-free assembly size of the pressure cylinder, that is, the standard size,...
