Description

Technical Field

[0001] The utility model relates to the technical field of tapered roller bearing production, specifically an automatic turning mechanism for the inner cone ring. Background Technique

[0002] Tapered roller bearings are mainly used to bear combined radial and axial loads, and are particularly suitable for scenarios mainly with radial loads. It has tapered raceway structures on the inner and outer rings, which can achieve general interchangeability. In the fields of construction machinery, railway vehicles, and wind power generation, tapered roller bearings exhibit the characteristics of high speed, high temperature, high precision, and high reliability. They are often installed in pairs to adjust the clearance to ensure the stable operation of the equipment.

[0003] The utility model with the authorization publication number of CN218289419U provides a bearing inner ring surface recognition and turning device, which belongs to the technical field of "tapered roller bearing production". The protected claims are: "It includes a base, on which there is a conveyor belt for conveying the bearing inner ring and a stop disk for recognizing the surface of the bearing inner ring. On the outside of the base, there is a turning mechanism for turning the bearing inner ring placed in the reverse direction; the stop disk is arranged on one side of the conveyor belt, and its installation height corresponds to the upper part of the bearing inner ring; the turning mechanism is installed on the other side of the conveyor belt and is arranged corresponding to the stop disk. The device of the utility model is based on the structure with different sizes at both ends of the inner ring of the tapered bearing. Through the arranged stop disk, the inner ring conveyed by the conveyor belt is automatically recognized, the inner ring with the large end at the upper part is selected out of the conveyor belt, and the bearing inner ring selected out of the conveyor belt is turned by the turning mechanism and then conveyed back to the original conveyor belt to complete the automatic surface recognition and turning operation of the inner ring, so as to meet the placement direction requirements of each bearing inner ring during the conveying process."

[0004] In this device, although the automatic surface recognition and turning operation of the inner ring can be completed, the addition of a transfer channel and a turning channel in this device increases the complexity, and the accuracy rate of turning a single bearing inner ring is relatively low. Therefore, we propose an automatic turning mechanism for the inner cone ring. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic turning mechanism for the inner cone ring to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] By setting up the turning-over component and starting two sets of hydraulic rods, the hydraulic rods drive the connecting frame to move, that is, drive two sets of first clamping plates and second clamping plates to abut against the inner ring of the bearing inward. When abutting, it will push the elastic piece to bend. The bending of the elastic piece drives the second clamping plate to rotate. Through the cooperation of the two sets of first clamping plates and second clamping plates, the inner ring of the bearing is clamped. At the same time, the bending of the elastic piece will push the telescopic rod to expand and contract. The telescopic rod in the middle expands and contracts, which will drive the contact block to move. The movement of the contact block will contact the induction point. The induction point will immediately react to the controller when receiving the induction. The controller controls the first motor to start. The first motor drives the screw rod to rotate. The rotation of the screw rod drives the lifting plate to rise, that is, drives the inner ring of the bearing to rise. Then start the second motor. The second motor drives the rotating block to rotate, that is, drives the inner ring of the bearing to turn over. After the turning-over is completed, start the first motor again to drive the inner ring of the bearing to descend, place the inner ring of the bearing on the conveyor belt, and then retract the hydraulic rods. In short, when the bottom diameter of the inner ring of the bearing at the arrival position is smaller than the top, the turning-over component will clamp the inner ring of the bearing for turning over, otherwise it will not turn over. Since no additional transfer channels and turning-over channels and other mechanisms are added, the complexity is reduced, and the accuracy of turning over a single inner ring of the bearing is improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1-4 shown, in this embodiment, the automatic turning mechanism for the inner ring of the cone includes a bottom plate 1, a vertical plate 2, and a turning component 3. The vertical plate 2 is fixedly connected to the bottom plate 1, and the turning component 3 is arranged on the vertical plate 2.

[0025] The turning component 3 includes a rotating block 301, a first clamping plate 304, an induction point 309, and a driving component 4. The rotating block 301 is arranged on one side of the vertical plate 2. One end of the rotating block 301 is fixedly connected to a hydraulic rod 302, and the driving end of the hydraulic rod 302 is fixedly connected to a connecting frame 303. The first clamping plate 304 is fixedly connected to one end of the connecting frame 303. A second clamping plate 305 is rotatably connected to the first clamping plate 304. A spring piece 306 is fixedly connected between the first clamping plate 304 and the second clamping plate 305. An expansion rod 307 is fixedly connected to the inner side of the spring piece 306. One end of the expansion rod 307 extends out of the first clamping plate 304 and is fixedly connected to a contact block 308. The induction point 309 is fixedly connected to the inner side of the connecting frame 303, and the contact block 308 and the induction point 309 are in movable contact. The driving component 4 is arranged inside the vertical plate 2.

[0026] During specific implementation, place the inner ring of the bearing between multiple baffles 502, and then start the conveyor belt 501. The conveyor belt 501 conveys the inner ring of the bearing to the position of the turning-over assembly 3. Start two sets of hydraulic rods 302. The hydraulic rods 302 drive the connecting frame 303 to move, that is, drive two sets of first clamping plates 304 and second clamping plates 305 to abut against the inner ring of the bearing inward. When abutting, it will push the elastic piece 306 to bend. The bending of the elastic piece 306 drives the second clamping plate 305 to rotate. Through the cooperation of the two sets of first clamping plates 304 and second clamping plates 305, the inner ring of the bearing is clamped. At the same time, the bending of the elastic piece 306 will push the telescopic rod 307 to stretch and contract. The telescopic rod 307 in the middle part stretches and contracts, which will drive the contact block 308 to move. The movement of the contact block 308 will contact the induction point 309. When the induction point 309 receives the induction, it will immediately react to the controller. The controller controls the first motor 401 to start. The first motor 401 drives the screw rod 403 to rotate. The rotation of the screw rod 403 drives the lifting plate 404 to rise, that is, drives the inner ring of the bearing to rise. Then start the second motor 405. The second motor 405 drives the rotating block 301 to rotate, that is, drives the inner ring of the bearing to turn over. After the turning-over is completed, start the first motor 401 again to drive the inner ring of the bearing to descend, place the inner ring of the bearing on the conveyor belt 501, and then retract the hydraulic rod 302. In short, when the bottom diameter of the inner ring of the bearing reaching the position is smaller than the top, the turning-over assembly 3 will clamp the inner ring of the bearing to turn it over, otherwise it will not turn it over.

[0027] In addition, it should be noted that the driving end of the second motor 405 and the screw rod 403 do not contact each other and do not interfere with each other. The two do not interfere with each other and can be driven separately. A damping mechanism is provided inside the telescopic rod 307. The telescopic rod 307 is a prior art and will not be elaborated too much.

[0028] Furthermore, the length of the first clamping plate 304 is less than that of the second clamping plate 305, which can prevent the first clamping plate 304 from contacting the outer side of the inner ring of the bearing when the bottom diameter is larger than the top.

[0029] Furthermore, a conveyor belt 501 is fixedly connected to the bottom plate 1, and multiple baffles 502 are fixedly connected to the conveyor belt 501. A main body 503 is arranged between the multiple baffles 502. By arranging the baffles 502, the main body 503 of the inner ring of the bearing can be limited.

[0030] Embodiment 2

[0031] As Figure 4As shown in the figure, the driving assembly 4 includes a first motor 401 and a second motor 405; the first motor 401 is fixedly connected to the top of the vertical plate 2, an empty slot 402 is formed in the vertical plate 2, the driving end of the first motor 401 extends into the empty slot 402 and is fixedly connected to a screw rod 403, an elevating plate 404 is threadedly connected to the outside of the screw rod 403, and the elevating plate 404 is slidably limited in the empty slot 402; the second motor 405 is fixedly connected to one side of the elevating plate 404, and the driving end of the second motor 405 penetrates through the elevating plate 404 and is fixedly connected to a rotating block 301.

[0032] During specific implementation, when the induction point 309 receives an induction, it will immediately respond to the controller, and the controller controls the first motor 401 to start. The first motor 401 drives the screw rod 403 to rotate, and the rotation of the screw rod 403 drives the elevating plate 404 to rise, that is, drives the inner ring of the bearing to rise. Then, the second motor 405 is started, and the second motor 405 drives the rotating block 301 to rotate, that is, drives the inner ring of the bearing to turn over.

[0033] Working principle: First, place the inner ring of the bearing between multiple baffles 502, then start the conveyor belt 501. The conveyor belt 501 conveys the inner ring of the bearing to the position of the turning-over assembly 3. Start two hydraulic rods 302, and the hydraulic rods 302 drive the connecting frame 303 to move, that is, drive two first clamping plates 304 and a second clamping plate 305 to abut against the inner ring of the bearing inward. When abutting, it will push the elastic piece 306 to bend. The bending of the elastic piece 306 drives the second clamping plate 305 to rotate. Through the cooperation of the two first clamping plates 304 and the second clamping plate 305, the inner ring of the bearing is clamped. At the same time, the bending of the elastic piece 306 will push the telescopic rod 307 to expand and contract. The expansion and contraction of the telescopic rod 307 in the middle part will drive the contact block 308 to move. The movement of the contact block 308 will contact the induction point 309. When the induction point 309 receives an induction, it will immediately respond to the controller. The controller controls the first motor 401 to start. The first motor 401 drives the screw rod 403 to rotate, and the rotation of the screw rod 403 drives the elevating plate 404 to rise, that is, drives the inner ring of the bearing to rise. Then, the second motor 405 is started, and the second motor 405 drives the rotating block 301 to rotate, that is, drives the inner ring of the bearing to turn over. After turning over is completed, start the first motor 401 again to drive the inner ring of the bearing to descend, place the inner ring of the bearing on the conveyor belt 501, and then retract the hydraulic rod 302. In short, when the bottom diameter of the inner ring of the bearing at the reached position is smaller than the top, the turning-over assembly 3 will clamp the inner ring of the bearing to turn it over. When the bottom diameter of the inner ring of the bearing at the reached position is larger than the top, since when the hydraulic rod 302 drives the elastic piece 306 to move, it will not contact the inner ring of the bearing, will not drive the telescopic rod 307 in the middle part to expand and contract, that is, will not drive the contact block 308 to move. If the contact block 308 does not move, it will not contact the induction point 309, and turning over will not be performed.
