A sampling method for an automatic sampling manipulator used for bearing ring parts

Abstract

The invention discloses an automatic sampling manipulator for a bearing ring part and a sampling method, and relates to the technical field of advanced manufacturing and automation. The automatic sampling manipulator comprises a control unit, a rack, a moving beam which is arranged blow the rack, a manipulator body which is arranged below the moving beam, a sucking device arranged at the end partof the manipulator body, and a pair of clamping claws, wherein the moving beam is connected to the rack through a first guide rail; the manipulator body is connected to the moving beam through a second guide rail; the manipulator body is connected to the second guide rail through a lifting device. According to the automatic sampling manipulator, a product in an annealing frame is automatically sampled, so that the sampling position can be accurately controlled; the sampling process is reliable and high in automation degree, and manual interference is avoided, so that mis-operation is avoided;the sucking device and the clamping claws are specially designed for an annular bearing ring, the bearing ring is sucked, and then the clamping claws pass through the bearing ring, so that the grabbing reliability is ensured, and the error rate is extremely low.

Description

technical field [0001] The invention relates to the technical field of advanced manufacturing and automation, in particular to a sampling method for an automatic sampling manipulator used for bearing ring parts. Background technique [0002] Spheroidizing annealing is mainly suitable for eutectoid steel and hypereutectoid steel, such as carbon tool steel, alloy tool steel, bearing steel, etc. These steels are air-cooled after rolling and forging, and the resulting structure is lamellar pearlite and reticular cementite. This kind of structure is hard and brittle, not only difficult to cut, but also easy to deform and crack in the subsequent quenching process. The spherical pearlite structure obtained by spheroidizing annealing, in which the cementite is in the form of spherical particles, is dispersed on the ferrite matrix. Compared with the flaky pearlite, it not only has low hardness and is easy to cut, but also can be processed after quenching. When heated, the austenite ...

Problems solved by technology

[0003] After spheroidizing annealing, it is necessary to grab samples at a specific position in the annealing frame filled with bearing rings. At present, it is manual grabbing. The control of the grabbing position is unstable, and misoperations such as forgetting and missing are prone to occur.
