[0001] The embodiments disclosed herein relate to the field of bearing processing technology, and more specifically, to a riveting mechanism for a self-lubricating tapered roller bearing. Background Technology
[0002] Bearing press riveting is a common connection method in mechanical assembly. It mainly uses pressure to cause plastic deformation between the bearing and the shaft or housing, forming a strong mechanical fit.
[0003] The existing riveting mechanism places the assembled bearing in the riveting groove and then moves downwards to rivet the bearing. However, during the riveting process, the bearing is prone to detach from the fixture and shift.
[0004] The aforementioned riveting mechanism is prone to bearing misalignment during the process of the bearing disengaging from the fixture and entering the riveting groove, which reduces the effectiveness of the device. Utility Model Content
[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a self-lubricating tapered roller bearing riveting mechanism to solve the technical problem in the prior art where bearings are prone to misalignment during the process of detaching from the fixture and entering the riveting groove.
[0006] According to one aspect, at least one embodiment of the present disclosure provides a self-lubricating tapered roller bearing riveting mechanism, which includes a support frame and a hydraulic cylinder, and further includes a lower pressure plate, a positioning block, a buffer rod, a buffer spring, a buffer plate, a positioning strip, a positioning piece, a positioning column, and a positioning plate; The lower pressure plate is installed at the output end of the hydraulic cylinder. Four sets of positioning blocks are installed on the outer side of the lower pressure plate. The buffer rod passes through the interior of the lower pressure plate. A buffer spring is installed on the upper surface of the lower pressure plate. The outer surface of the buffer rod passes through the buffer spring. Buffer plates are installed at the top of the buffer rod and the buffer spring. The positioning strip is installed at the bottom end of the buffer rod. The positioning strip is slidably connected to the interior of the lower pressure plate through a positioning groove. A positioning plate is installed on the lower surface of the positioning strip. The positioning post is threaded through the interior of the positioning strip. A positioning plate is installed on the outer surface of the positioning post.
[0007] In a preferred embodiment of the self-lubricating tapered roller bearing riveting mechanism of this utility model, in order to better support the support frame, a support plate is installed on the lower surface of the support frame, and a support leg is installed on the lower surface of the support plate.
[0008] In a preferred embodiment of the self-lubricating tapered roller bearing riveting mechanism of this utility model, in order to better fix the unriveted bearing, a fixing plate is installed on the upper surface of the support plate, and a fixing tube is installed on the outer side of the fixing plate.
[0009] In a preferred embodiment of the self-lubricating tapered roller bearing riveting mechanism of this utility model, in order to be applicable to bearings of different diameters, a fixing rod is inserted through the interior of the fixing tube, and the outer surface of the fixing rod penetrates the interior of the fixing plate.
[0010] In a preferred embodiment of the self-lubricating tapered roller bearing riveting mechanism of this utility model, in order to prevent the fixing rod from loosening during use, a fixing pin is threaded through the outer surface of the fixing tube, and one end of the fixing pin threaded into the fixing tube abuts against the fixing rod.
[0011] In a preferred embodiment of the self-lubricating tapered roller bearing riveting mechanism of this utility model, in order to better fix the bearing, a contact plate is installed at the inner end of the fixing rod, and a limit spring is installed inside the contact plate.
[0012] In a preferred embodiment of the self-lubricating tapered roller bearing riveting mechanism of this utility model, in order to prevent the bearing from being deflected during the downward movement of the lower pressure plate, a limiting plate is installed at the top of the limiting spring, and the limiting plate is slidably connected to the contact plate through a limiting groove.
[0013] As a preferred embodiment of the self-lubricating tapered roller bearing riveting mechanism of this utility model, in order to enhance the limiting effect of the device, a mold body is installed on the upper surface of the support plate, and an insertion groove is opened on the upper surface of the mold body, the size of the insertion groove being adapted to the size of the positioning piece.
[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the bearing is blocked on both sides by positioning plates, and then the positioning strip contacts the bearing to limit its position. Compared with the direct riveting of bearings in the prior art, this device can limit and block the side of the bearing, which can prevent the bearing from being misaligned during the riveting process.
[0015] In this disclosure, the lower pressure plate moves downward, causing the positioning block to move downward, so that the positioning block slides into the limiting groove and pushes the limiting piece downward. Compared with the prior art where the bearing directly enters the riveting groove after being released from the fixture, this device can restrict the movement trajectory of the bearing from multiple angles, avoiding bearing displacement during the movement of the device.

Therefore, they should not be construed as limitations on this disclosure.
[0024] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0025] like Figures 1-4 As shown, it illustrates a self-lubricating tapered roller bearing riveting mechanism according to an embodiment of the present disclosure, which includes a support frame 1 and a hydraulic cylinder 2, and also includes a lower pressure plate 3, a positioning block 4, a buffer rod 5, a buffer spring 6, a buffer plate 7, a positioning strip 8, a positioning plate 9, a positioning column 10 and a positioning plate 11. like Figure 3As shown, the lower pressure plate 3 is installed at the output end of the hydraulic cylinder 2. The hydraulic cylinder 2 moves up and down at the output end through an external hydraulic pump station. Four sets of positioning blocks 4 are installed on the outer side of the lower pressure plate 3. The buffer rod 5 passes through the interior of the lower pressure plate 3. The upper surface of the lower pressure plate 3 is equipped with a buffer spring 6. The outer surface of the buffer rod 5 passes through the buffer spring 6. The top of the buffer rod 5 and the buffer spring 6 are equipped with buffer plates 7. The positioning strip 8 is installed at the bottom end of the buffer rod 5. The positioning strip 8 is slidably connected to the interior of the lower pressure plate 3 through the positioning groove. In fact, it is the lower pressure plate 3 that rivets the bearing. The positioning strip 8 only plays the role of positioning and preventing the bearing from deviating. There is a distance between the positioning strip 8 and the lower pressure plate 3 in the initial state. The lower surface of the positioning strip 8 is equipped with a positioning plate 9. The positioning post 10 is threaded through the interior of the positioning strip 8. The outer surface of the positioning post 10 is equipped with a positioning plate 11. The positioning plate 11 extends into the interior of the bearing as the positioning strip 8 moves downward. The positioning plate 11 blocks the inner wall of the bearing to prevent the bearing from deviating.
[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a support plate 21 is installed on the lower surface of the support frame 1, and a support leg 22 is installed on the lower surface of the support plate 21. A fixing plate 12 is installed on the upper surface of the support plate 21. A fixing tube 13 is installed on the outer side of the fixing plate 12. A fixing rod 14 passes through the inside of the fixing tube 13. The outer surface of the fixing rod 14 passes through the inside of the fixing plate 12. A fixing pin 15 is threaded through the outer surface of the fixing tube 13. One end of the fixing pin 15, threaded into the fixing tube 13, abuts against the fixing rod 14. A contact plate 16 is installed at the inner end of the fixing rod 14. A limit spring 17 is installed inside the contact plate 16. A limit piece 18 is installed at the top of the limit spring 17. The limit piece 18 is slidably connected to the contact plate 16 through a limit groove. The positioning block 4 can slide into the limit groove as the lower pressure plate 3 moves downward, and pushes the limit piece 18 to move downward along the limit groove. The upper surface and the upper surface of the lower pressure plate 3 are at the same level. The thickness of the lower pressure plate 3 is greater than the thickness of the positioning block 4. Therefore, when the lower pressure plate 3 rivets the bearing, the positioning block 4 does not compress the limit spring 17 to the minimum. The upper surface of the support plate 21 is equipped with a mold body 19. The mold body 19 is a mold for riveting tapered roller bearings. A set of inverted conical grooves are opened inside the mold body 19. A semi-circular groove with the same radius as the tapered roller is opened on its inner wall. The semi-circular groove is used to hold the tapered roller. The upper surface of the mold body 19 is provided with an insertion groove 20. After the positioning piece 9 pushes the bearing into the mold body 19 along with the positioning strip 8, the positioning piece 9 slides in along the insertion groove 20, so that the lower pressure plate 3 can contact the mold body 19 and rivet the bearing. The size of the insertion groove 20 is adapted to the size of the positioning piece 9. In order to better slide the positioning piece 9 into the insertion groove 20.
[0027] In this embodiment, the positioning plate 11 is manipulated to insert the positioning post 10 into the positioning strip 8, and then the positioning post 10 is rotated clockwise to install the positioning plate 11. Place the bearing on the mold body 19, operate the fixing rod 14 to move inward along the fixing tube 13, the fixing rod 14 moves inward and drives the contact plate 16 to move inward, the contact plate 16 moves inward and drives the limit spring 17 to move inward, the limit spring 17 moves inward and drives the limit piece 18 to move inward, the contact plate 16 moves inward and contacts the bearing, operate the fixing pin 15 to insert into the fixing tube 13, and then rotate the fixing pin 15 clockwise to press the fixing rod 14 against it; The hydraulic cylinder 2 is pressurized by an external hydraulic pump station, causing the output end of the hydraulic cylinder 2 to move downward. The downward movement of the output end of the hydraulic cylinder 2 drives the lower pressure plate 3 to move downward. The downward movement of the lower pressure plate 3 drives the positioning block 4 to move downward. The downward movement of the lower pressure plate 3 drives the buffer rod 5 to move downward. The downward movement of the lower pressure plate 3 drives the buffer spring 6 to move downward. The downward movement of the buffer rod 5 and the buffer spring 6 drives the buffer plate 7 to move downward. The downward movement of the buffer rod 5 drives the positioning strip 8 to move downward. The downward movement of the positioning strip 8 drives the positioning plate 9 to move downward. The downward movement of the positioning strip 8 drives the positioning column 10 to move downward. The downward movement of the positioning column 10 drives the positioning plate 11 to move downward. Positioning bar 8 moves downward to contact the bearing and push it downward. Positioning piece 9 moves downward to block the front and rear sides of the bearing. Positioning pin 10 moves downward to extend positioning plate 11 into the bearing. Positioning plate 11 moves downward into the bearing and blocks the inner wall of the bearing to prevent the bearing from shifting during downward movement. Positioning block 4 moves downward to slide into the limiting groove. Positioning block 4 moves downward to drive limiting piece 18 to move downward. Limiting piece 18 moves downward along the limiting groove and compresses limiting spring 17. The positioning piece 9 moves downward and slides into the insertion groove 20, so that the positioning strip 8 contacts the upper surface of the mold body 19 and stops moving, so that the buffer rod 5 and the buffer piece 7 also stop moving with the positioning strip 8. As the lower pressure plate 3 moves downward, it gradually stretches the buffer spring 6. The positioning strip 8 slides into the lower pressure plate 3 along the positioning groove, and then the lower pressure plate 3 cooperates with the mold body 19 to rivet the bearing. After the riveting is completed, the pressure inside the hydraulic cylinder 2 is released by the external hydraulic pump station, so that the output end of the hydraulic cylinder 2 moves upward and drives the lower pressure plate 3 to move upward. The lower pressure plate 3 moves upward and drives the positioning block 4 to move upward. The positioning block 4 moves upward along the inside of the limiting groove, so that the limiting spring 17 rebounds and drives the limiting piece 18 to move upward. The limiting piece 18 moves upward along the limiting groove, and finally the positioning block 4 slides out from the limiting groove. At the same time, the downward pressure plate 3 moves upward, causing the buffer rod 5 to move upward. The upward movement of the buffer rod 5 causes the buffer plate 7 to move upward, causing the buffer spring 6 to rebound. The upward movement of the buffer rod 5 causes the positioning strip 8 to move upward. The upward movement of the positioning strip 8 causes the positioning plate 9 to move upward. The positioning plate 9 slides out along the inside of the insertion groove 20. The upward movement of the positioning strip 8 causes the positioning post 10 to move upward. The upward movement of the positioning post 10 causes the positioning plate 11 to move upward. The upward movement of the positioning plate 11 moves out of the bearing. The positioning plate 9 and the positioning strip 8 move upward and disengage from the bearing, releasing the bearing. The operator removes the riveted bearing from inside the mold body 19, and then puts a set of unriveted bearings into the mold body 19. The above operation is repeated to rivet the bearings.
[0028] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
