Four-point contact bearing inner and outer ring groove super-fine machine of novel structure

Abstract

The invention discloses a four-point contact bearing inner and outer ring groove super-fine machine of a novel structure. The super-fine machine comprises a machine frame body, a vibration device, an oilstone fixture, an automatic compensation and alarm device and a PLC control system, wherein the machine frame body is provided with a workbench; the vibration device is used for providing high-frequency vibration actions for an oilstone and arranged on the workbench; the oilstone fixture is used for clamping the oilstone, the rear end of the oilstone fixture is arranged on an output shaft of the vibration device, and the oilstone is clamped at the front end of the oilstone fixture; the automatic compensation and alarm device is used for sending out an alarm signal after the oilstone is damaged or abraded and is arranged on the oilstone fixture; and the PLC control system is in communication connection with the vibration device and the automatic compensation and alarm device. According to the four-point contact bearing inner and outer ring groove super-fine machine of the novel structure, whether the oilstone is damaged or not can be precisely judged, and in addition, the labor intensity of staff is relieved; and the situation that the undamaged oilstone is unloaded from the oilstone fixture is avoided, and not only is resource wasting avoided, but also the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a superfinishing machine for inner and outer ring channels of a four-point contact bearing with a new structure. Background technique [0002] The bearing superfinishing machine uses a relatively low pressure to press the oil stone to the inner and outer ring channels of the rotating bearing to form a surface contact state. At the same time, the oil stone performs axial vibration at a higher frequency. [0003] When the bearing superfinishing machine is working, the oil stone used for grinding the bearing is very easy to damage. In the existing technology, the staff generally has the following types to determine whether the oil stone is damaged: 1. There is no alarm device, and the judgment of whether the oil stone is damaged mainly depends on manual work. Judging by observation, this method not only increases the labor intensity of the staff, but also makes it difficu...

Problems solved by technology

[0003] When the bearing superfinishing machine is working, the oil stone used for grinding the bearing is very easy to damage. In the existing technology, the staff generally has the following types to determine whether the oil stone is damaged: 1. There is no alarm device, and the judgment of whether the oil stone is damaged mainly depends on manual work. Judging by observation, this method not only increases the labor intensity of the staff, but also makes it difficult to judge accurately; 2. Judging by counting, when the specified number of products is processed, the alarm device will send out an alarm signal, regardless of whether the old oilstone is damaged or not Workers are required to disassemble it from the oil stone fixture and replace it with a new oil stone. It is difficult for the bearing superfinishing machine with this structure to alarm according to the actual situation, which not only causes a waste of resources, but also increases the production cost.
