Embodiment Construction

[0022] The design concept of the present invention is to provide a stable and referenceable grinding path for the grinding head 9 of the manipulator, and keep the position of the grinding head 9 on the end face of the gear 10 coincident with the edge of the gear.

[0023] A chamfering and grinding manipulator for gear end faces, such as Figure 1-6 As shown, it includes a mechanical arm 1, a substrate 2, a servo motor 3, a lead screw 4, a nut 6, a force sensor 6, a probe 7, a high-speed motor 8, a grinding head 9, a gear 10, and a servo rotary table 11.

[0024] The path planning part provided by the present invention is: a main controller (not visible in the figure), a mechanical arm 1 , a force sensor 6 , a probe 7 and a substrate 2 . The force sensor 6 is installed at the end of the mechanical arm 1 through the substrate 2 , and the probe 7 is installed at the end of the force sensor 6 . The main controller controls the action of the mechanical arm 1, and the force sensor ...

Abstract

The invention provides a mechanical hand for carrying out chamfering polishing on the end face of a gear. A probe at the tail end of the mechanical hand and a polishing head are arranged to be an integrated linkage whole, a master controller enables the probe to make contact with the gear at the set contact pressure value, and the probe is arranged to be a sensor which monitors the contact pressure value in real time. The master controller adjusts the contact pressure value at the next moment. The displacement path of the probe is the polishing path of the polishing head. The invention furtherprovides a polishing method of the mechanical hand for carrying out chamfering polishing on the end face of the gear. The method comprises the steps that 1, the probe makes contact with the edge of the gear at the set contact pressure value; 2, when the gear is rotated, a force sensor feeds the real-time contact pressure value of the probe and the gear back to the master controller; 3, the position of the probe at the next moment is adjusted to enable the probe to be in tight fit with the gear, and copying description is carried out the gear contour; and 4, the polishing head and the probe are in integrated linkage, and the copied contour described by the probe is converted to be the polishing path of the polishing head. The contact force of the probe and the surface of the gear is controllable, the machining precision is high, and polishing quality is good.

Description

technical field [0001] The invention relates to a grinding manipulator, in particular to a force-controlled profiling gear grinding manipulator. Background technique [0002] The gear is the core component of the transmission mechanism, and is an important component to realize the shift guide and transmit the movement. The gear can be used after grinding to reduce the impact vibration and improve the service life of the gear. With the advancement and development of technology, the requirements for the performance and reliability of the transmission mechanism are getting higher and higher, and the corresponding requirements for the quality of gear processing are becoming more and more stringent. Most of the existing gear grinding mechanisms use non-controllable grinding methods. Low, grinding quality is not easy to guarantee. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a force-based control profiling gear grinding ...
