[0002] The sensor positioning tool currently used is to loosely screw the crankshaft speed sensor bracket on the gear housing with two bolts, and pass the sensor positioning tool through the sensor mounting hole. The small boss at one end of the tooling is stuck in the upper pointing mark groove of the signal disk. The small boss at the positioning end is easily deformed, and the positioning process is not rigorous. The installation position of the crankshaft speed sensor bracket positioned in this way is inaccurate, resulting in unreasonable positioning, and ultimately losing the positioning and guiding functions, seriously affecting the production of the engine.

[0007] The knob is nested on the outside of the anti-slip head, and a threaded rod is fixedly connected to the middle position of the inner side of the knob.

[0008] Preferably, one end of the threaded rod away from the knob is movably connected to a bearing, and the knob can rotate freely on the outer side of the anti-slip head through the bearing.

[0009] Preferably, two symmetrically arranged sliding grooves are provided on the side of the handle.

[0010] Preferably, a ball nut is fixedly connected to the inner side of the limiting step near the slide groove via a sliding block.

[0011] Preferably, a movable cavity is provided in the inner cavity of the handle near the position of the ball nut, and the ball nut is nested in the side surface of the threaded rod and can slide freely along the axial direction of the movable cavity.

[0012] Preferably, the diameter of the first tooling step is larger than the diameter of the handle and smaller than the maximum diameter of the second tooling step.

[0013] Preferably, the second tooling step and the limiting step can slide freely along the axial direction on the side surface of the handle.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0015] 1. In the present invention, the double-step design of the first tooling step and the second tooling step can respectively fit with the crankshaft shock absorber tooth top and the upper surface of the bracket, ensuring that the crankshaft speed sensor positioning tool can quickly and accurately locate the installation position of the crankshaft sensor bracket, thereby smoothly installing the crankshaft speed sensor and improving work efficiency.

[0016] 2. In the present invention, the block at one end of the first tooling step can cooperate with the tooth groove on the crankshaft to ensure that the position of the crankshaft speed sensor positioning tool is stable and accurate. By turning the knob, the knob can drive the ball nut through the threaded rod, thereby realizing the adjustment of the position of the second tooling step and the limit step, so that the crankshaft speed sensor positioning tool can fit different brackets, thereby improving adaptability.
