Problems solved by technology
The on-site reliability test period of the whole machine is long, the cost is high, and the requirements for the test personnel are high, and the loading and state monitoring conditions of the test are difficult to control. Therefore, a reliability test of the tool spindle system of the gear shaping machine that can simulate the loading of the cutting load is studied. Taiwan is of great significance
[0003] The tool spindle of the gear shaping machine performs up and down reciprocating gear shaping movement during work, and only one side of the gear shaping tool participates in the processing, so the tool spindle system is subjected to dynamic unbalanced forces, which are more prone to failure

The invention discloses a tool spindle system reliability test bench of a gear shaping machine, which includes: a loading follower device, a Z-direction loading device, a tool spindle speed measuring device, and a spindle tool monitoring unit; the spindle tool monitoring unit passes through a door The type frame is installed at the lower part of the tool spindle under test; the tool spindle speed measuring device is installed at the lower end of the Z-direction loading device; the Z-direction loading device is installed in the loading follow-up device, and the loading follow-up device is fixed on the horizontal iron through its bracket. Above; the loading follow-up device drives the Z-direction loading device and the tool spindle speed measuring device to reciprocate linearly along the Z direction; the tool spindle speed measuring device can realize the synchronous measurement of the spindle speed when the tool spindle reciprocates along the Z direction; simulate the tool Z direction Displacement monitoring and tool spindle radial runout monitoring both adopt non-contact measurement methods; the radial runout of the tool spindle and the displacement of the simulated tool are obtained by analyzing the detection signals of the eddy current sensor and the laser displacement sensor.
Description
technical field [0001] The invention belongs to the field of reliability testing of gear processing machine tools, in particular to a reliability testing platform for tool spindle systems of gear shaping machines. Background technique [0002] Gear processing machine tool is the main equipment for gear processing. As one of the gear processing machine tools, the gear shaping machine is suitable for the processing of external and internal gear teeth. It is an efficient and high-precision gear processing method. However, due to the large processing range and large load changes of the gear shaping machine, the tool spindle performs high-frequency reciprocating motion for a long time, and during the machining process, the gear shaping tool participates in cutting on one side, resulting in unilateral dynamic cutting force, which imposes an imbalance on the tool spindle system. force, resulting in greater damage to its sealing structure and main drive system, which greatly affects...
