The words "one", "an" or "the" and the like used in the patent application specification and claims of the present invention do not express quantity restrictions, but indicate the existence of at least one; the words "first", "second" and "third" used in this document shall not be regarded as restrictions on the order of components, but are only used to distinguish different components; words such as "include" or "comprise" and the like indicate that the elements or objects appearing before "include" or "comprise" include the elements or objects listed after "include" or "comprise" and their equivalents, but do not exclude other elements or objects with the same function.

[0025] In order to more clearly describe the specific structural composition of the flexible loading and unloading device for automatic detection of small batches and multiple types of bearings, combined with the attached Figure 1-3 Describe this embodiment: like Figure 1 or Figure 2 As shown, a flexible loading and unloading device for automatic detection of small batches and multiple models of bearings includes a working platform 1, on which a feeding turntable 2 and a rotating drive mechanism for driving the feeding turntable 2 to rotate are provided; the feeding turntable 2 has at least two turntable mounting positions 3 that are rotationally symmetrical along its center, and each turntable mounting position 3 is provided with a bearing fixture; each bearing fixture includes a lifting plate 4, a guide rod driving plate 5 and a bearing outer diameter guide rod 6; the center lines of the turntable mounting position 3, the lifting plate 4 and the guide rod driving plate 5 coincide, there are no less than three bearing outer diameter guide rods 6, and they are arranged around the center line of the turntable mounting position 3, and each bearing outer diameter guide rod 6 is parallel to the center line of the turntable mounting position 3, and the feeding turntable 2 is provided with a slide groove 201 that is slidably matched with each bearing outer diameter guide rod 6 and can enable the bearing outer diameter guide rod 6 to slide along the radial direction of the lifting plate 4; The lifting plate 4 is located at the top of the bearing tooling, and the lifting plate 4 is provided with a second slide groove 401 for the bearing outer diameter guide rod 6 to pass through, and the second slide groove 401 is symmetrical with the first slide groove 201 up and down; the guide rod driving plate 5 is provided with a third slide groove 501 for the bearing outer diameter guide rod 6 to pass through, and the third slide groove 501 intersects with the first slide groove 201 and forms an angle at the intersection, and the guide rod driving plate 5 rotates relative to the turntable mounting position 3 to adjust the radial position of the bearing outer diameter guide rod 6 on the lifting plate 4; the working platform 1 is provided with a lifting drive mechanism that drives the lifting plate 4 to rise and fall along the axial direction of the bearing outer diameter guide rod 6.

[0026] The feeding turntable 2 is generally provided with two, which are divided into a loading turntable ( Figure 1 The left turntable) and the unloading turntable ( Figure 1The rotating disc on the right side of the middle), each feeding rotating disc 2 has multiple bearing fixtures, forming multiple working positions, and the rotating driving mechanism drives the feeding rotating disc 2 to rotate so that the bearing fixtures at different working positions can be rotated to the loading position or unloading position. The tested bearing 16 is lifted by the jacking driving mechanism at the loading position of the loading rotating disc, grabbed by an external simple manipulator, and then lowered to the unloading position of the unloading rotating disc by the jacking driving mechanism; The lifting plate 4 of each bearing fixture is used to support the bottom surface of the measured bearing 16. The lifting plate 4 slides with the bearing outer diameter guide rod 6 through its slide groove 401, so that the lifting plate 4 can be lifted and lowered along the axial direction of the bearing outer diameter guide rod 6; at least three bearing outer diameter guide rods 6 are used to clamp the outer cylindrical surface of the measured bearing 16, and the bearing outer diameter guide rods 6 have a sufficient length to place multiple measured bearings; the radial position of the bearing outer diameter guide rods 6 can be adjusted to adapt to the measured bearings of different outer diameter sizes, and at the same time, the measured bearing is at the center of the lifting plate 4; the radial position of the bearing outer diameter guide rods 6 is adjusted by rotating the guide rod driving plate 5; See also Figure 3 When adjusting the bearing outer diameter guide rod 6, the guide rod driving plate 5 is rotated to change the intersection position of the slide groove 3 501 and the slide groove 1 201 in the radial direction, thereby constraining the position of the bearing outer diameter guide rod 6 to change. Therefore, when designing the slide groove 1 201 and the slide groove 3 501, it is necessary to ensure that the two can rotate and intersect, and the tangent of the slide groove 3 501 forms an acute angle with the tangent of the slide groove 1 201. The slide groove 2 401 cannot interfere with the interlacing and adjustment of the slide groove 1 201 and the slide groove 3 501. This slide groove 2 401 can be symmetrical with the slide groove 1 201. For example, the slide groove 1 201 and the slide groove 2 401 are linear grooves (the length direction of the linear groove can be along the radial direction of the lifting plate 4), and the slide groove 3 501 is an arc groove, and the interlaced position of the arc groove and the linear groove can be continuously changed during rotation; when the slide groove 1 201 and the slide groove 2 401 are linear grooves, the slide groove 3 501 can also be a linear groove, but the slide groove 1 201 needs to ensure that it cannot completely overlap with the slide groove 3 501 at any time.

[0027] In the above embodiment, the rotary drive mechanism includes a turntable motor 7 and a turntable shaft system 8 installed on the working platform 1. The rotation center of the feed turntable 2 is connected to the output shaft of the turntable motor 7 through the turntable shaft system 8; the turntable shaft system 8 and the feed turntable 2 are driven to rotate by the turntable motor 7 to adjust the position of the bearing tooling on the feed turntable 2.

[0028] Specifically, the lifting drive mechanism includes a lifting cylinder 9 on the working platform 1 and a lifting rod 10 fixed on the telescopic arm of the lifting cylinder 9. The feeding turntable 2 is provided with a lifting hole 11 that can avoid the guide rod driving disk 5 and directly contact the lifting disk 4. When the bearing fixture carrying the measured bearing rotates to the upper material position or the lower material position, the lifting cylinder 9 drives the lifting rod 10 to lift or lower the lifting disk 4, and the lifting hole 11 rotates with the feeding turntable 2, but does not produce angular interference with the guide rod driving disk 5 and the bearing outer diameter guide rod 6.

[0029] A positioning mechanism for detecting the rotation position of the lifting disk 4 is provided on the working platform 1. The positioning mechanism includes a proximity switch 12 arranged on the working platform 1. The lifting disk 4 is provided with a notch 13 that can rotate correspondingly with the proximity switch 12. The number of the notches 13 corresponds to the number of the lifting disks 4. When the proximity switch 12 detects the notch 13, it indicates that a lifting disk 4 is corresponding to the upper material position or the lower material position; the working platform 1 is also provided with a sensing mechanism for detecting whether there is a bearing to be measured on the lifting disk 4. The sensing mechanism can specifically be a photoelectric switch 17. The photoelectric switch 17 is located near the upper material position or the lower material position. When the photoelectric switch 17 has a sensing signal, it indicates that the lifting disk 4 at the upper material position or the lower material position is full of bearings to be measured.

[0030] Furthermore, the feed turntable 2 is provided with a drive disk locking mechanism 14 capable of limiting the rotation of the guide rod drive disk 5; the drive disk locking mechanism 14 can be a bolt, and the bolt is loosened when adjusting the guide rod drive disk 5, and the guide rod drive disk 5 is moved to a suitable angle. When locked, the guide rod drive disk 5 and the feed turntable 2 are connected by the bolt to limit the relative rotation of the two, so that the bearing outer diameter guide rod 6 is stably maintained in its position.

[0031] Specifically, the lower end of each bearing outer diameter guide rod 6 is detachably connected to two locking blocks 15, and the two locking blocks 15 are slidably clamped on the upper and lower sides of the feed turntable 2. After removing one locking block 15, the corresponding bearing outer diameter guide rod 6 can be directly removed from the feed turntable 2.

[0032] The working platform 1, as the supporting platform of the whole device, can be made of high-quality carbon structural steel; the lifting plate 4 and the bearing outer diameter guide rod 6 need to directly contact the measured bearing, and in order to avoid wear of the measured bearing, they can be made of soft aluminum material.

[0033] The parts not described in detail in the above embodiments are prior art.

[0034] It should be noted that although the present invention is described by the above embodiments, the present invention may also have other various embodiments. Without departing from the spirit and scope of the present invention, it is obvious that those skilled in the art may make various corresponding changes and deformations to the present invention, but these changes and deformations should all fall within the scope of protection of the appended claims of the present invention and their equivalents.
