A sorting device and sorting method for segmentally assembled valve core and valve seat

Abstract

The invention discloses a sorting device and a sorting method for segmentally assembling valve cores and seats, relates to the field of quality inspection, and solves the problem of low assembly precision of valve cores and seats, which includes a photosensitive device, a light source device, and a sorting mechanism And a control computing system connected with the above three devices, the light source device is arranged directly above the center of the photosensitive device, and the sorting mechanism includes a lifting universal joint that can rotate 360 ​​degrees and is arranged at the center of the photosensitive device , the photosensitive device is provided with a feeding channel for transporting the spool to be sorted to the sorting mechanism and several sorting channels corresponding to each tolerance section, and the feeding channel and the sorting channel are both connected to the The center of the photosensitive device is connected. The invention has the advantages of sorting the valve core and the valve seat with the closest size to the same section, allowing the valve core and valve seat to achieve the maximum utilization rate, and improving the qualified rate of assembly.

Description

technical field [0001] The invention relates to the field of quality inspection, in particular to a sorting device and a sorting method for segmentally assembling valve cores and valve seats. Background technique [0002] Ball valves can be seen everywhere in life and can be used everywhere, but there are some common problems in the assembly process of ball valves, such as: whether the ball roundness in manufacturing is qualified, assembly problems caused by size mismatch of valve core and seat during assembly, mechanical Common problems such as excessive pressure and low pressure cause deformation of the spool and affect life. And the present invention aims at the qualified product that the valve core and the valve seat are all within the tolerance range in the assembly process, but the imperfect assembly problem occurs because the valve core and the valve seat are the largest size and the other is the smallest size. It is caused by different positions of the valve core an...
