Description

Technical Field

[0001] The utility model relates to the technical field of harmonic reducer bearings, and specifically relates to a needle roller pressing device for bearings. Background Technique

[0002] Harmonic reducer bearings are a type of supporting bearings specifically designed for harmonic reducers. Most of the bearings used in harmonic reducers are needle roller bearings. A needle roller bearing is a roller bearing with cylindrical rollers. Relative to its diameter, the rollers are both thin and long. Such rollers are called needle rollers. Despite having a small cross-section, the bearing still has a high load-bearing capacity. The needle roller bearing is equipped with thin and long rollers, so its radial structure is compact. When its inner diameter size and load capacity are the same as those of other types of bearings, its outer diameter is the smallest, and it is particularly suitable for supporting structures where the radial installation size is limited.

[0003] During the installation process of the needle roller bearing, the needle rollers need to be pressed into the inside of the bearing. During the use of an existing needle roller pressing device for bearings, the needle rollers will be pressed into the inside of the bearing in sequence, which will increase the installation time of the needle roller bearing and reduce the production and installation speed of the needle roller bearing.

[0004] Therefore, a needle roller pressing device for bearings is specifically proposed. Content of the Utility Model

Specific embodiments

[0022] 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 of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: A plurality of first support frames 2 are welded to the top of the base 1, a needle storage structure 5 is fixed to the top of the first support frames 2, a plurality of second support frames 3 are welded to the top of the base 1, a top plate 4 is welded to the top of the second support frames 3, an electric disengaging device 7 is fixed to the top of the top plate 4 by bolts, the output end of the electric disengaging device 7 penetrates through the inside of the top plate 4 and is provided with a positioning plate 6, a pressing plate 9 is integrally formed at the bottom of the positioning plate 6, a plurality of feeding structures 10 are equidistantly installed on the outside of the needle storage structure 5, a sliding groove 15 is opened on the top of the base 1, a slide plate 14 is slidably installed inside the sliding groove 15, a pressing platform 11 is fixed to the top of the slide plate 14, and a first needle roller limiting seat 12 is welded to the top of the pressing platform 11.

[0024] Specifically, as Figure 1 , Figure 2 and Figure 3As shown, during use, the skateboard 14 is drawn out from the inside of the chute 15, and the pressing-in table 11 fixed to the top of the skateboard 14 is drawn out together, so that the bearing seat without needle rollers is sleeved above the pressing-in table 11. Since the first needle roller limiting seat 12 is fixed to the top of the pressing-in table 11, the installation position of the needle rollers can be restricted by the first needle roller limiting seat 12 to prevent the installation position of the needle rollers from shifting. Subsequently, the internal parts of the multiple feeding structures 10 are filled with needle roller parts. Through the extrusion of the internal structure of the feeding structure 10, the needle roller parts installed inside the multiple feeding structures 10 can enter the inside of the needle storage structure 5 simultaneously. Subsequently, the extension of the output end of the electric jack 7 can drive the positioning plate 6 to move downward. Since the pressing plate 9 is fixed to the bottom of the positioning plate 6, the pressing plate 9 will move downward along with the positioning plate 6. As the pressing plate 9 moves downward, the pressing plate 9 can be inserted into the inside of the needle storage structure 5, so that the needle roller parts squeezed into the inside of the needle storage structure 5 can be simultaneously pressed out of the inside of the needle storage structure 5 and pressed into the bearing seat sleeved on the top of the pressing-in table 11. After the needle rollers are pressed in, the pressing plate 9 is pulled out from the inside of the needle storage structure 5. Subsequently, through the extrusion inside the feeding structure 10, the needle roller parts can be continuously squeezed and pushed into the inside of the needle storage structure 5 to prepare for the installation of the next bearing. Subsequently, the bearing with needle rollers is removed from above the pressing-in table 11, and the bearing seat without needle rollers is reinstalled above the pressing-in table 11 and the above operations are repeated to perform continuous installation. Through this device, multiple needle rollers can be pressed into the inside of the bearing seat at one time, which speeds up the pressing speed of the needle rollers of the bearing and improves the production speed of the needle roller bearing.

[0025] Embodiment 2: Two support slide bars 8 are respectively welded to both sides of the top of the positioning plate 6, and the two support slide bars 8 respectively slide through the inside of the top plate 4. The needle storage structure 5 includes a needle storage box 501. A pressing-in groove 502 is opened at the top of the needle storage box 501. A plurality of pressing-in holes 503 are equidistantly opened at the bottom of the needle storage box 501. A second shock-absorbing limiting seat 504 is installed inside the pressing-in groove 502. A plurality of rubber tightening openings 505 are equidistantly installed at the bottom of the needle storage box 501, and the rubber tightening openings 505 are used in cooperation with the pressing-in holes 503. The inner diameter of the pressing plate 9 is larger than the outer diameter of the second shock-absorbing limiting seat 504, and the outer diameter of the pressing plate 9 is smaller than the outer diameter of the needle storage structure 5.

[0026] Specifically, such as Figure 1 、 Figure 3 and Figure 4As shown, when the positioning plate 6 moves up and down, the support slide rods 8 fixed on both sides of the top of the positioning plate 6 will slide inside the top plate 4, thus ensuring the stability of the positioning plate 6 during the movement. Since the needle storage structure 5 includes a needle storage box 501, the needle storage box 501 can store the needles to be pressed in. Since a second shock-absorbing and limiting seat 504 is installed inside the needle storage box 501, the second shock-absorbing and limiting seat 504 can limit the needles entering the inside of the needle storage box 501, further improving the accuracy of the installation position of the needles. Since a plurality of pressing holes 503 are equidistantly arranged at the bottom of the needle storage box 501, the needle parts can be pressed out of the inside of the needle storage box 501 through the pressing holes 503, and a rubber tightening mouth 505 is installed at the bottom of the pressing holes 503. The rubber tightening mouth 505 can tightly wrap the outside of the needle parts. When the needle parts stored inside the needle storage box 501 are not squeezed, the rubber tightening mouth 505 can prevent the needle parts from falling out of the inside of the needle storage box 501. After being squeezed by the pressing plate 9, the needle parts can be pressed out of the inside of the needle storage box 501 through the pressing holes 503, and the diameter of the rubber tightening mouth 505 is enlarged. Since the depth of the pressing plate 9 is greater than the depth of the needle storage box 501, when the pressing plate 9 is completely pressed into the inside of the needle storage box 501, the needles can be completely pressed out of the inside of the needle storage box 501.

[0027] Embodiment 3: The feeding structure 10 includes a feeding groove 1001, and the inside of the feeding groove 1001 is connected to the inside of the needle storage box 501. A pull rod 1005 is slidably installed inside the feeding groove 1001, and a push plate 1004 is welded to one end of the pull rod 1005. One end of the pull rod 1005 extends out of the inside of the feeding groove 1001, and a pull ring 1002 is welded to one end of the pull rod 1005. The top of the feeding groove 1001 is open, and a spring 1003 is sleeved on the outside of the pull rod 1005. A limiting groove 13 is respectively opened on both sides of the sliding groove 15, and a slider 16 is respectively welded to both sides of the sliding plate 14. The two sliders 16 are respectively slidably installed inside the limiting grooves 13.

[0028] Specifically, as Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, since the top of the feeding chute 1001 is open, the needle roller parts can be put into the inside of the feeding chute 1001 from the top of the feeding chute 1001. When putting the needle rollers, pulling the pull ring 1002 outwards can drive the pull rod 1005 to slide outwards, and at the same time compress the spring 1003 sleeved outside the pull rod 1005. Since a push plate 1004 is fixed at one end of the pull rod 1005, the needle rollers can be extruded by the push plate 1004. The needle roller parts placed inside the feeding chute 1001 can be sequentially pushed into the inside of the needle storage box 501 by the rebounding force generated by the compression of the spring 1003. Since a limiting groove 13 is respectively formed on both sides of the sliding chute 15, and the sliding blocks 16 fixed on both sides of the sliding plate 14 are slidably installed inside the limiting groove 13, during the process of pulling and pushing the sliding plate 14, the sliding blocks 16 will slide along the opening direction of the limiting groove 13, so as to ensure that the sliding position of the sliding plate 14 will not deviate and ensure that the sliding plate 14 will not completely slide out of the inside of the sliding chute 15, which is convenient for use.

[0029] Working principle: Put the needle roller parts into the inside of the feeding chute 1001 from the top of the feeding chute 1001. Pulling the pull ring 1002 outwards can drive the pull rod 1005 to slide outwards, and at the same time compress the spring 1003 sleeved outside the pull rod 1005. Since a push plate 1004 is fixed at one end of the pull rod 1005, the needle rollers can be extruded by the push plate 1004. The needle roller parts placed inside the feeding chute 1001 can be sequentially pushed into the inside of the needle storage box 501 by the rebounding force generated by the compression of the spring 1003. The needle rollers entering the inside of the needle storage box 501 can be limited by the second shock limiting seat 504. Sleeve the bearing seat without needle rollers above the press-in table 11. Since a first needle roller limiting seat 12 is fixed on the top of the press-in table 11, the installation position of the needle rollers can be restricted by the first needle roller limiting seat 12 to prevent the installation position of the needle rollers from shifting. Subsequently, the extension of the output end of the electric jack 7 can drive the pressure plate 9 to insert into the inside of the needle storage structure 5, so as to press out the needle roller parts squeezed into the inside of the needle storage structure 5 at the same time and press them into the bearing seat sleeved on the top of the press-in table 11. After the needle rollers are pressed in, pull out the pressure plate 9 from the inside of the needle storage structure 5. Subsequently, through the extrusion inside the feeding structure 10, the needle roller parts can be continuously squeezed and pushed into the inside of the needle storage structure 5 to prepare for the installation of the next bearing. Subsequently, take the bearing with needle rollers off above the press-in table 11, and then reinstall the bearing seat without needle rollers above the press-in table 11 and repeat the above operations to perform continuous installation.
