Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a tapered roller bearing retaining ring riveting machine. Background Technology

[0002] Tapered roller bearings are separable bearings, with both the inner and outer rings having tapered raceways. These bearings are classified into single-row, double-row, and four-row tapered roller bearings according to the number of rows of rollers. Shaft retaining rings, also known as shaft elastic retaining rings or snap rings, are elastic fasteners installed on grooved shafts, achieving axial positioning through elasticity and groove fit. Their inner diameter is slightly smaller than the shaft diameter, requiring snap ring pliers to expand them before installation into the shaft groove. They are suitable for shaft components in hydraulic systems, pneumatic systems, and various mechanical equipment.

[0003] The existing retaining rings are installed manually by using clamps to open them and install them inside and outside the bearing. When a large number of retaining rings are installed, the installation efficiency is reduced. When riveting the retaining rings, it is necessary to manually place the retaining rings and bearings before riveting. The original equipment uses a unit placement table, which results in waiting time between riveting operations, resulting in low production capacity. Utility Model Content

[0023] like Figures 1-4As shown, it illustrates a tapered roller bearing retaining ring riveting machine according to an embodiment of the present invention, comprising: a base plate 1, a device box 2 fixedly installed on the upper end of the base plate 1, a support plate 3 fixedly installed on the front of the upper end of the device box 2, an mounting plate 4 installed on the inner side of the support plate 3, a lifting rod 5 installed on the upper end of the mounting plate 4, a positioning frame 6 fixedly installed at the top of the lifting rod 5, and a calibration camera 7 fixedly installed at the front end of the mounting plate 4; Rotating gear 8 is fixedly installed on the top of the upper end of device box 2, and a driving gear 9 is meshed with the upper end of rotating gear 8. A station turntable 10 is fixedly installed on the upper end of driving gear 9. A connecting block 11 is installed at the bottom of the lower end of station turntable 10. A rotating platform 12 is installed at the center of the upper end of station turntable 10. Clamping rods 13 are fixedly installed on both sides of the upper end of rotating platform 12.

[0024] For example, such as Figure 3 As shown, a mounting cavity 14 is fixedly opened inside the clamping rod 13, a push rod 15 is fixedly installed inside the mounting cavity 14, a clamping plate 16 is fixedly installed on the outside of the push rod 15, and a bearing body 17 is sleeved on the upper end of the clamping rod 13.

[0025] For example, such as Figure 2 As shown, the support plate 3 is symmetrically installed on the left and right sides of the device box 2 with the device box 2 as the center reference. The mounting plate 4 and the base plate 1 form a flange connection. The positioning frame 6 has a groove inside.

[0026] For example, such as Figure 3 As shown, the upper end of the workstation turntable 10 is "H" shaped. The connecting block 11 is symmetrically installed on the front and rear sides of the lower end of the workstation turntable 10 with the workstation turntable 10 as the center reference. The clamping rod 13 is symmetrically installed on the front and rear sides of the upper end of the workstation turntable 10 with the workstation turntable 10 as the center reference.

[0027] For example, such as Figure 4 As shown, the clamping rod 13 has an "I" shaped cross section. The pushing rod 15 is symmetrically installed on the front and rear sides of the interior of the mounting cavity 14 with the center of the cavity as the reference. There are four sets of pushing rods 15. The front end of the clamping plate 16 is arc-shaped and an anti-slip strip is fixedly installed on the front end of the clamping plate 16.

[0028] In some examples, the base plate 1 is placed on the ground as the base of the entire device. The device box 2 is equipped with a rotating structure to provide power for the rotation of the workstation turntable 10. The workstation turntable 10 is designed as a dual-workstation structure, with two clamping rods 13 installed at its upper end. The bearing is placed on the upper end of the first clamping rod 13 at the rear workstation. The rotating gear 8 is started by the controller 19 (PLC). The rotating gear 8 meshes with the driving gear 9, driving the driving gear 9 to rotate. The driving gear 9 drives the upper workstation turntable 10 to rotate. After the rotation is completed, the first clamping rod 13, which was originally located at the rear end, rotates to the front end position. At this time, the first clamping rod 13 is rotated to the front end position. Two bearings are placed on the upper end of the clamping rod 13 on the other side of the workstation. The rotation position is monitored in real time by the calibration camera 7 to prevent deviation. In order to enhance the stability of the workstation turntable 10 when it is in a fixed position, a lifting rod 5 is vertically installed below its front end. The lifting rod 5 is fixed to the upper end of the base plate 1 through the flange connection of the support plate 3. The top surface of the lifting rod 5 is connected to the positioning frame 6. When the workstation turntable 10 rotates into place and needs to be fixed, the lifting rod 5 is activated, which drives the positioning frame 6 to move upward. The groove inside the positioning frame 6 mates with the connecting block 11 at the bottom of the workstation turntable 10, thereby providing support and fixation for the front end of the workstation turntable 10.

[0029] For example, such as Figure 5-7 As shown, it illustrates a tapered roller bearing retaining ring riveting machine in another embodiment of the present invention, including a frame 18 fixedly installed on the upper end of a rotating table 12, a controller 19 fixedly installed on the left side of the upper end of the frame 18, a motor 20 fixedly installed at the front of the top of the frame 18, and a hydraulic cylinder 21 fixedly installed at the lower end of the motor 20.

[0030] For example, such as Figure 6 As shown, the lower end of the hydraulic cylinder 21 is fixedly connected to the riveting upper mold 22, the lower end of the riveting upper mold 22 is fixedly connected to the riveting lower mold 23, the rear end of the riveting upper mold 22 is fixedly connected to the riveting upper mold 24, and the lower end of the riveting upper mold 24 is fixedly installed with the riveting lower mold 25.

[0031] For example, such as Figure 7 As shown, the frame 18 is "L" shaped, the riveting upper mold 22 is a replacement structure, the riveting upper mold 22 and the riveting lower mold 23 are connected internally, and the riveting upper mold 24 and the riveting lower mold 25 are connected internally.

[0032] In some examples, the lower end of the rotary table 10 is connected to the device box 2 via a gear structure (providing rotational power), and the upper end of the rotary table 10 is connected to the L-shaped frame 18 via a rotating platform 12 (providing upper support and stability). A motor 20 is installed on the upper end of the L-shaped frame 18, and the motor 20 drives a vertically mounted hydraulic cylinder 21, which is located directly above the placed bearing. When the retaining ring is installed inside the bearing body 17, a riveting upper die 22 is installed at the lower end of the hydraulic cylinder 21 (connected via a flange). The bearing that needs to have its internal retaining ring riveted is placed on the riveting lower die 23, and the retaining ring is placed inside the riveting lower die 23. The hydraulic cylinder 21 is activated to drive the riveting upper die 22 to press down, completing the retaining ring installation. When the bearing body 17 is outside, the riveting upper mold 24 is installed at the lower end of the hydraulic cylinder 21 (connected by a flange). The bearing that needs to be riveted with an external retaining ring is placed on the riveting lower mold 25, and the retaining ring is placed inside the riveting lower mold 25. The hydraulic cylinder 21 is started to drive the riveting upper mold 24 to press down, completing the retaining ring installation. When a retaining ring riveting operation is being performed at one station, the worker can simultaneously place the bearing to be processed at another station. After the bearing riveting at the front station is completed (or the bearing placement / preparation at the rear station is completed), the station turntable 10 is started to rotate through the controller 19 to exchange the positions of the two stations (i.e., the station that has completed riveting moves to the rear, and the station that has placed the bearing to be processed moves to the front), preparing for the next round of operation.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model 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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
