The air extractor 9 and one end of the air passage 32 penetrating through the bottom plate 1 are connected in a sealing manner by a connecting pipe 91, for example, one end of the connecting pipe 91 penetrates through the base 1 and is inserted into the air passage 32 to realize structural sealing. The connection line is provided with a pressure detection device 92, such as a barometer, a pressure sensor, etc.
In the present embodiment, in order to improve the interlocking performance of the assembly equipment, the pressure detection device 92 is a pressure sensor and is connected to a PLC controller (not shown). The PLC is also connected with a hydraulic oil cylinder 8 and an air extractor 9.
In this embodiment, a bearing retainer ring rigging equipment's theory of operation is:
the retainer ring 3' is placed on the supporting surface 31 at the top end of the retainer ring platform 3, and the two are in surface contact without clearance. After the ball bearing 2 ' is installed in the bearing chamber 11 ' of the flange 1 ', it is fitted over the central positioning post 4, with the retainer chamber 12 ' facing the retainer ring 3 '. The PLC controller controls the air extractor 9 to work, and air extraction treatment is carried out on the air passage 32. If the bearing retainer ring 3 'is placed on the supporting surface 31 of the retainer ring platform 3 and the installation direction is correct, the bearing retainer ring 3' is in contact sealing with the supporting surface 31, the air passage 32 is closed, and the pressure detection device 92 obtains the current pressure value. If the pressure value is also in the set interval, the PLC controller controls the hydraulic oil cylinder 8 to work, and the piston rod 81 presses the flange 1' downwards. The flange 1' is first brought into contact with the upper end of the sleeve 6. The flange 1 'continues to move downwards and the sleeve 6 presses the spring 5 and gradually exposes the bearing ring 3'. Finally, the retainer ring 3 'and the supporting surface 31 of the retainer ring platform 3 are inserted into the retainer ring chamber 12' of the flange 1 ', so that the retainer ring 3' is quickly assembled. On the contrary, if the bearing retainer ring 3' is not placed on the supporting surface 31 of the retainer ring platform 3 or the installation direction is wrong, the pressure detection device 92 obtains the current pressure value, and the hydraulic oil cylinder 8 is not started. On the one hand, the equipment has the characteristics of simple structure, small size, convenience in operation, high automation degree, high assembly efficiency and relatively low processing cost. On the other hand, the device judges and separates through the pressure value, can judge whether the bearing retainer ring is installed correctly, is simple and reliable, and reduces the product rejection rate.
