Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing technology, and in particular to a flanged device for the outer ring of a full complement needle roller bearing. Background Technology

[0002] Full complement needle roller bearings are mainly used in universal joints. After the outer ring is stamped, one end is closed and the other end is open. After the needle rollers are arranged on the outer ring, the outer ring needs to be flanged inward to cover the needle rollers.

[0003] The existing flanging fixtures are achieved by roller extrusion. During flanging, the bearing is rotating while the roller is stationary. With this type of flanging fixture, the needle rollers installed inside the outer ring of the bearing are easily dislodged as the outer ring rotates. The dislodged needle rollers need to be manually reinstalled into the outer ring, which affects work efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a full-fill needle roller bearing outer ring flanging device that can prevent needle rollers from falling off during flanging.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a full-fill needle roller bearing outer ring flanging device, which has an operating table. A base is fixed on the right end of the operating table panel. A support seat that can be moved and adjusted left and right is provided on the base. An installation plate that can be moved and adjusted up and down is provided on the left side of the support seat. A pneumatic chuck that clamps the outer ring of the needle roller bearing is provided on the installation plate. Two rollers that are rotatably installed at the left end of the operating table panel are spaced apart. The inner side of the rollers has a pressing slope corresponding to the flanging surface of the outer ring of the needle roller bearing.

[0006] Specifically, to achieve the rotation of the two rollers, a mounting bracket is fixed to the left end of the operating panel, and a bearing seat is mounted on the mounting bracket. A transmission shaft is rotatably mounted inside the bearing seat. A servo motor is mounted below the operating panel, and a belt drive mechanism is provided between the output shaft of the servo motor and the left end of the transmission shaft. An adapter block is fixed to the right end of the transmission shaft, and two supports are fixed on the adapter block. A support shaft is installed between the supports, and the two rollers are rotatably mounted on the support shaft with their pressing inclined surfaces facing each other.

[0007] Furthermore, to facilitate the adjustment of the center position of the needle roller bearing installed on the pneumatic chuck, a base plate is fixed on the base, a sliding plate that can move left and right is slidably provided on the base plate, a right-angle seat is fixed on the sliding plate, the support seat is slidably provided on the horizontal plate of the right-angle seat, a hydraulic cylinder is installed on the vertical plate of the right-angle seat, and the piston rod of the hydraulic cylinder is fixedly connected to the right end of the support seat.

[0008] Preferably, the base plate and the slide plate, the right-angle seat and the support seat, and the mounting plate and the left side of the support seat all adopt a dovetail groove structure for sliding fit.

[0009] Preferably, the movement between the base plate and the slide plate, and between the mounting plate and the left side of the support base, is achieved by a screw and nut mechanism.

[0010] The beneficial effects of this utility model are: This utility model adopts a flanging method in which the bearing does not rotate and the roller rotates, so the needle rollers installed in the outer ring of the bearing will not fall off during the flanging process, thereby improving work efficiency and ensuring that the performance of the needle roller bearing is not affected.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] like Figures 1-3The device shown is a full complement needle roller bearing outer ring flanging device, including an operating table 1 with a panel. A channel steel-shaped mounting bracket 7 is fixed on the left side of the operating table 1 panel. A bearing seat 8 is mounted on the flat plate of the mounting bracket 7. A transmission shaft 9 is supported by a bearing in the bearing seat 8. A servo motor 10 is installed below the operating table 1. The output shaft of the servo motor 10 is connected to the left end of the transmission shaft 9 by a belt drive mechanism 11. A transition block 12 is fixed on the right end of the transmission shaft 9. Two supports 13 are fixed at a distance on the transition block 12. A support shaft 14 is installed between the supports 13. Rollers 6 are rotatably mounted at both ends of the support shaft 14. The inner side of the roller 6 has a pressing slope 6-1 corresponding to the flanging surface of the outer ring of the needle roller bearing. After installation, the pressing slopes 6-1 of the two rollers 6 are opposite to each other.

[0018] A rectangular base 2 is fixed to the right side of the control panel 1. A base plate 15 is fixed to the base 2. A sliding plate 16 that can move left and right is slidably mounted on the base plate 15. A right-angle seat 17 is fixed on the sliding plate 16. The right-angle seat 17 consists of a horizontal plate and a vertical plate. A support seat 3 is slidably mounted on the horizontal plate of the right-angle seat 17. The left side of the support seat 3 faces the roller 6 and is equipped with an adjustable mounting plate 4. A pneumatic chuck 5 is provided on the mounting plate 4 to hold the outer ring of the needle roller bearing. A hydraulic cylinder 18 is mounted on the vertical plate of the right-angle seat 17. The piston rod of the hydraulic cylinder 18 is fixed to the right end of the support seat 17.

[0019] To simplify the structure, dovetail grooves are used to achieve sliding fit between the base plate 15 and the slide plate 16, between the right-angle seat 17 and the support seat 3, and between the mounting plate 4 and the left side of the support seat 3.

[0020] Furthermore, the base plate 15 and the slide plate 16, as well as the mounting plate 4 and the left side of the support base 3, are driven by a screw and nut mechanism 19 to realize the horizontal movement of the slide plate 16 and the vertical movement of the mounting plate 4, respectively.

[0021] The control panel 1 is also equipped with a control cabinet to control the entire process of the flanging operation.

[0022] During the flanging process, the bearing filled with needle rollers is clamped onto the pneumatic chuck 5 and driven by the screw and nut mechanism 18. The center position of the needle roller bearing is adjusted, and the servo motor 10 is started, driving the drive shaft 9 to rotate via the belt drive mechanism 11. The two rollers 6 rotate synchronously with the drive shaft 9. Then, the hydraulic cylinder 18 is activated, pushing the support base 3 towards the rollers 6, causing the outer ring of the bearing to approach the two rollers 6 until it is pressed tightly against them. As the rollers 6 rotate, the pressing inclined surfaces 6-1 of the two rollers 6 continuously press against both sides of the outer ring of the bearing until the inward flanging of the outer ring is completed. Because the bearing does not rotate while the rollers 6 rotate, the needle rollers installed inside the outer ring of the bearing will not fall out during the flanging process, thereby improving work efficiency and ensuring that the performance of the needle roller bearing is not affected.

[0023] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
