Description
Technical Field
The utility model belongs to the technical field of the bearing, concretely relates to rotatory flexibility detection device of subassembly roller in tapered roller bearing.
Background
Quality problems of inflexible rotation or blocking and the like occur due to products sent to customers by an automobile line of a certain limited company at the early stage; in addition, because a detection line of a certain equipment limited company does not have a device for detecting the rotation flexibility of the component roller in the tapered roller bearing, the function of the detection item is not available; through research, the newly purchased detection equipment has high cost and long period.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims at providing a rotatory flexibility detection device of subassembly roller in tapered roller bearing.
The utility model adopts the following technical scheme for accomplishing the above purpose:
a detection device for the rotation flexibility of a roller of an assembly in a tapered roller bearing is provided with a fixed shaft sleeve fixed on the outer side of a rotating shaft; the rotating shaft is sleeved outside the mandrel and is in interference fit with the mandrel; two stop blocks are symmetrically distributed on the outer circular surface of the fixed shaft sleeve; the stop block is an arc-shaped block and is attached to the outer circular surface of the fixed shaft sleeve; a gap is reserved between the two stop blocks; the two check blocks are fixedly connected with the fixed shaft sleeve into a whole through fixing screws I respectively; the stop block is a structure rotating along with the fixed shaft sleeve and the rotating shaft; the detection device is also provided with a detection switch; the detection switch is a proximity switch; the detection switch is arranged on the outer side of the circumference where the stop block is located, and gaps are formed between the detection switch and the circumference where the stop block is located; the detection switch is fixed on the bottom plate through the switch bracket.
The top end of the mandrel is fixedly connected with the inner assembly of the tapered roller bearing to be tested, and the lower end of the mandrel is connected with a rotary driving mechanism positioned at the lower part of the bottom plate.
The utility model provides a device for detecting the rotation flexibility of a roller of an assembly in a tapered roller bearing, which utilizes the rotation function of a main shaft for vibration measurement on the original YGL-100 vibration measurement, oil coating and material arrangement equipment, and can cause the phenomena of main shaft stalling or inflexible rotation when detecting a problem product because the main shaft rotates because a motor drives the main shaft to rotate through a belt; the fixed bearing is sleeved on the outer side of the rotating shaft, the two stop blocks are symmetrically distributed on the outer circular surface of the shaft sleeve, and the rotating condition of the main shaft is detected in real time through the arranged proximity switch; when a problem product appears, the proximity switch sends a signal to the PLC, because the proximity switch only has two working states of '0' or '1', two timers of the PLC are utilized to detect the two states within 1.5 seconds, when the two state signals of '0' or '1' exceed the time of 1.5 seconds, the PLC sends an instruction to stop the circulating work of the equipment and sends an alarm signal, the red alarm lamp flashes, an operator manually takes out the problem product before going, and then the automatic circulating working state is restarted.
