Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 3, the bearing retainer height detection device of this embodiment includes a workbench 1, a material channel 2 is arranged on the workbench 1, a detection station is arranged on the material channel 2, a lower die detection block 3 is installed on the detection station, a lifting cylinder 4 for driving the lower die detection block 3 to move up and down is installed below the material channel 2, a bearing positioning mechanism 6 is installed outside the workbench 1, and the bearing positioning mechanism 6 is used for moving and positioning a bearing 8 to be detected, which is placed on the material channel 2 in advance, on the detection station. An upper die detection head 5 is arranged right above the lower die detection block 3, and the height detection of the bearing retainer is realized through the matching of the lower die detection block 3 and the upper die detection head 5.

In the present embodiment, the bearing positioning mechanism 6 includes a first driving cylinder 61, a second driving cylinder 62, a guide rod 63, a support plate 64, and a positioning plate 65. Wherein, the guide bar 63 is arranged along the length direction of the material channel 2, the support plate 64 is arranged on the guide bar 63, the first driving cylinder 61 is used for driving the support plate 64 to move along the guide bar 63, and the second driving cylinder 62 is used for driving the first driving cylinder 61, the guide bar 63 and the support plate 64 to move along the width direction of the material channel 2 integrally. The locating plate 65 is fixed on the backup pad 64, and one side of locating plate 65 towards the material way 2 is opened has the outer lane camber assorted arc breach 651 with waiting to examine bearing 8, and from this, the locating plate 65 can be with waiting to examine bearing 8 spacing in arc breach 651 and then move to the detection station under the drive of backup pad 64 on.

The top of the outer ring of the lower mold detection block 3 of the present embodiment has an annular wall 31 extending upward, and the annular wall 31 is used to abut against the bottom of the retainer 81 to be detected.

Install support frame 7 on workstation 1, support frame 7 is including horizontal support platform 71, and it has the through-hole (for showing in the figure) to open on horizontal support platform 71, and last mould detection head 5 is located horizontal support platform 71 below, and the top of going up mould detection head 5 has guide post 51 that upwards extends and pass the through-hole, and the cover is equipped with stop collar 52 on guide post 51, and stop collar 52 is located the top of horizontal support platform 71 and the external diameter of stop collar 52 is greater than the aperture of through-hole.

The detection process and the principle of the detection device are as follows:

Firstly, the bearing 8 to be detected is moved to the detection station of the material channel 2, namely to the position right above the lower die detection block 3 through the positioning block 65 of the bearing positioning mechanism 6, and at the moment, the retainer 81 of the bearing 8 to be detected is just positioned right above the annular wall 31 of the lower die detection block 3.

Then, the positioning block 65 is moved out of the detection station, the lower die detection block 3 and the bearing 8 to be detected move upwards synchronously under the driving of the lifting cylinder 4, when the bearing 8 to be detected moves upwards to collide with the upper die detection head 5, the upper die detection head 5 is driven to start moving upwards, because the stroke of the lifting cylinder 4 is preset, the upward movement distance of the lower die detection block 3 and the bearing to be detected 8 is a fixed value, the moving distance of the upper die detecting head 5 is related to the height of the retainer 81, the standard height of the retainer 81 is preset by a program, if the height of the retainer to be detected is lower, the upward moving distance of the upper die detection head 5 is correspondingly reduced, the control program judges that the height of the retainer is not qualified, if the height of the retainer to be detected is higher, the upward moving distance of the upper die detection head 5 is correspondingly increased, and the control program also judges that the height of the retainer is not qualified. Unqualified bearings can be removed in subsequent processes.

Finally, the upper die detection head 5 is reset downward by gravity until the stop collar 52 is seated on the horizontal support table 71, and the resetting is completed.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, the present invention can be modified or improved without departing from the principle of the present invention, and these modifications are all considered to be within the protection scope of the present invention.
