[0002] Bearing steel pipe is a seamless steel pipe made by hot rolling or cold rolling process. It is mainly used for manufacturing ordinary rolling bearing rings, and it is necessary to effectively detect whether the bearing steel pipe is bent during the production process.

[0003] After retrieval, a bearing steel pipe detection device with the publication (announcement) number CN216558723U points out that when detecting the bearing steel pipe, the operator places two groups of clamping plates inside the diameter of the bearing steel pipe, and then through the relative movement of the two groups of clamping plates, the bearing steel pipe can be fixed. After turning on the power, the bearing steel pipe is driven to pass through the first half ring and the second half ring. When the bending degree of the bearing steel pipe changes, the first half ring and the second half ring of the steel pipe drive the rotating rod and the conductor rod to rotate horizontally through the connecting rod and the support rod. When the conductor rod touches the conduction block, at this time, a complete closed circuit is formed through the conductor rod, the second wire body, the warning light, the first wire body, the power supply and the third wire body, that is, the warning light will light up, indicating that the bending degree of the bearing steel pipe is not within the qualified range. The detection efficiency is fast, and a warning will be given immediately when the bending degree is unqualified. The operation is simple, the efficiency is fast, and it saves time and effort.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a bearing steel pipe production, processing and detection device.

[0026] The utility model provides Figures 1-3 The bearing steel pipe production, processing and inspection device shown includes a base plate 1 and a protective cover 2. A support plate 3 is fixedly provided on the top of the base plate 1 and inside the protective cover 2. A rotating rod 4 is rotatably provided on the upper end of the inner part of the support plate 3. A connecting block 5 is provided on the rod wall fixed sleeve of the rotating rod 4. A plurality of detection rings 6 symmetrically arranged in a circumferential manner are provided on the outer side of the connecting block 5. A connecting positioning component is provided between the detection ring 6 and the connecting block 5. The connecting positioning component includes a threaded rod 7. The threaded rod 7 is fixedly connected to the outer wall of the detection ring 6. A plurality of thread grooves symmetrically arranged in a circumferential manner are opened on the outer wall of the connecting block 5. The threaded end of the threaded rod 7 is threaded in the thread groove. A rotating block 16 is provided on the rod wall fixed sleeve of the threaded rod 7.

[0027] Before inspecting the bearing steel tube, place the device at the inspection position, and connect multiple inspection rings 6 to the connecting block 5 through the cooperation of the threaded rod 7 and the threaded groove, then insert the steel tube into the inspection ring 6 of the corresponding inner diameter specification. As the steel tube is continuously inserted, if the steel tube bends, the bending position will conflict with the inner wall of the inspection ring 6, making it impossible for the steel tube to continue to pass through the inspection ring 6. At this time, the bending position can be determined to complete the inspection of the steel tube.

[0028] In order to select the corresponding test ring 6 according to the specifications of the steel pipe, Figures 1-2As shown, the inner diameters of multiple detection rings 6 are arranged in a decreasing annular manner. The rear end of the rotating rod 4 passes through the protective cover 2 and is provided with a rotation conversion mechanism for driving the multiple detection rings 6 to rotate and change positions. The rotation conversion mechanism includes a worm 8. The upper end of the back side of the protective cover 2 is fixedly provided with a mounting plate 9. The worm 8 is rotatably connected to the side wall of the mounting plate 9. The rear end of the rotating rod 4 passes through the protective cover 2 and is fixedly sleeved with a worm gear 10. The worm gear 10 is arranged in cooperation with the worm 8. One end of the worm 8 away from the mounting plate 9 is fixedly provided with a crank 11.

[0029] Before detecting the steel pipe, determine the outer diameter specification of the steel pipe and rotate the crank 11. Through the cooperation of the worm 8 and the worm gear 10, the rotating rod 4 can drive the connecting block 5 to rotate. At this time, the multiple detection rings 6 can rotate out of the protective cover 2 and be selected. When the inner diameter of the detection ring 6 matches the steel pipe, stop rotating the crank 11 and place the detection ring 6 outside the protective cover 2. Later, the steel pipe can be inserted into the detection ring 6 to complete the detection work.

[0030] And in order to stably support the steel pipe during the detection process, as Figure 3 shown, both lower ends of the outer walls of the multiple detection rings 6 are fixedly provided with connecting plates 12. Both ends of the two connecting plates 12 away from each other are fixedly provided with guide plates 13. The bottom of the inner wall of the guide plate 13 is fixedly provided with a support block 15 through a spring 14. The guide plate 13 is arranged in an arc shape.

[0031] Through the arrangement of the guide plate 13, before the steel pipe is inserted into the detection ring 6, the steel pipe can be placed inside the guide plate 13 and supported by the spring 14 and the support block 15. As the steel pipe is inserted into the detection ring 6, the elastic force of the spring 14 can push the steel pipe into close contact with the inner wall of the detection ring 6, so as to accurately detect whether the steel pipe is bent and improve the detection accuracy.

[0032] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
