Description

Technical Field

[0001] The utility model relates to the technical field of hub bearing assembly, in particular to a riveting machine which is convenient for bearing clamping processing. Background Art

[0002] The wheel hub bearing is a part that connects the tire (rotating part) / brake disc (rotating part) and the steering knuckle. Its main function is to reduce friction for the rotating pair and also to transmit force. It bears very large radial loads (vehicle weight) and axial loads (lateral force or lateral impact force of the tire when turning). There are three generations of wheel hub bearings. The first generation bearing structure is the simplest, mainly an inner ring, an outer ring and steel balls. And the cost is also the lowest. Since the first generation bearing is independent of the steering knuckle and the wheel hub, it is necessary to press the inner ring of the bearing onto the wheel hub and the outer ring of the bearing into the steering knuckle during online assembly. However, due to the complex assembly process, the requirements for equipment and process control are relatively high. The second is poor performance. Because the process cannot be accurately controlled during installation, the performance deviation of the bearing after press-fitting is also large, and the overall performance is low, and it is gradually eliminated. The structure of the second generation bearing is slightly more complicated, and the wheel hub is integrated on the basis of the first generation bearing. Compared with the first generation bearing, the process of pressing into the wheel hub is omitted during assembly, but it still needs to be assembled with an interference fit with the steering knuckle. The assembly accuracy is only slightly higher than that of the first generation bearing. Currently, except for some car manufacturers that still insist on using it on the rear wheel hub, it is used less and less like the first generation bearing, and eventually disappears. In terms of integration, the inner ring of the third generation bearing is integrated with the wheel hub, and the outer ring is integrated with the flange connecting the steering knuckle, which can be connected to the steering knuckle by bolts. The assembly accuracy is greatly improved. And because all dimensions are precisely controlled by the supplier, the performance is the best.

[0003] In the prior art, all three generations of wheel hub bearings need to be assembled with rivets on the flange, and are generally installed manually using a rotary riveting machine. However, the rotary riveting machine in the prior art cannot fix the wheel hub bearing when installing rivets on the wheel hub bearing. This requires the installers to hold the wheel hub bearings and assemble them one by one, which not only consumes a lot of time and has low efficiency, but also requires a lot of labor costs.

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a rotary riveting machine which is convenient for bearing clamping processing and can clamp the wheel hub bearing without the need for manual hand-holding to turn the knob, thus solving the problem that the wheel hub bearing needs to be manually held when assembling rivets and cannot be fixed by a rotary riveting machine.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose of being able to clamp the wheel hub bearing without the need for manual hand-held knob rotation, the utility model provides the following technical solutions: a rotary riveting machine that is convenient for bearing clamping processing, comprising a base plate, a support platform is provided on one side of the base plate, a rivet mounting platform is provided on the other side, a limited back plate is provided on the support platform through a telescopic rod, a clamping platform is provided at the center of the base plate, a triangular bracket is processed at the center of the clamping platform, a fixing piece is provided at the upper end of the clamping platform, a threaded hole is provided on the fixing piece, and the fixing piece is connected to the screw rod through the threaded hole, the wheel hub bearing is placed in the triangular bracket and fixed by the fixing piece, a rivet disk is provided on the rivet mounting platform through a connecting shaft, and a rotary rivet head is provided on the rivet disk.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a rotary riveting machine that is convenient for bearing clamping processing, and has the following beneficial effects:

[0014] 1. A riveting machine that is convenient for bearing clamping processing can clamp the wheel hub bearing for riveting knobs by means of a fixing part and a clamping table. Since the clamping table uses two inclined surfaces of a triangular groove for limiting, the clamping groove can be suitable for wheel hub bearings with different apertures. After clamping, the rivet head is driven to rotate and the rivet knob is turned onto the wheel hub bearing through the feeding of the connecting shaft. During the riveting process, the limiting back plate can ensure that the wheel hub bearing will not be dislocated due to the vibration generated during the riveting, thereby ensuring the accuracy of the rivet riveting.

[0015] 2. This rotary riveting machine is convenient for bearing clamping processing. Through the setting of the rivet disc, the rotary riveting machine can perform rotary riveting of multiple rivets at the same time, avoiding multiple clamping and fixing of the wheel hub bearing during rotary riveting, improving the efficiency of rivet assembly, and reducing the rotary riveting error. At the same time, multiple rivets are riveted at the same time, so that the force applied to the wheel hub bearing during rivet installation is uniform, and the phenomenon of uneven force in a single direction causing deformation of the wheel hub will not occur, thereby ensuring the production quality of the wheel hub bearing after riveting.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 A rotary riveting machine convenient for bearing clamping processing comprises a base plate 1, a support platform 2 is arranged on one side of the base plate 1, a rivet mounting platform 3 is arranged on the other side, a limited back plate 5 is arranged on the support platform 2 through a telescopic rod 4, a clamping platform 6 is arranged at the center of the base plate 1, a triangular bracket is processed at the center of the clamping platform 6, a fixing piece 7 is arranged at the upper end of the clamping platform 6, a threaded hole is arranged on the fixing piece 7, and the fixing piece 7 is connected to a screw rod 8 through the threaded hole, the screw rod 8 is arranged in the inner cavity of the screw rod 8 before and after the clamping platform 6, the bottom of the screw rod 8 is connected to a driver 9, a wheel hub bearing 14 is placed in the bracket and fixed by the fixing piece 7, a rivet disc 10 is arranged on the rivet mounting platform 3 through a connecting shaft, and a rotary riveting head 11 is arranged on the rivet disc 10.

[0022] First, place the riveting machine on a stable workbench and ensure that the power supply is connected stably. Check the components, such as the support table 2, rivet mounting table 3, telescopic rod 4, limit back plate 5, clamping table 6, triangular bracket, fixing piece 7, screw 8, driver 9, etc., to ensure that they are intact and working properly. Place the wheel hub bearing 14 to be processed in the triangular bracket of the clamping table 6.

[0023] Ensure that the bearing is placed in the correct position and is stable and motionless. Start the driver 9 to rotate the screw 8. Since the threaded hole on the fixing member 7 is connected to the screw 8, the rotation of the screw 8 will drive the fixing member 7 to move downward, and then fix the hub bearing 14 in the triangular bracket through the fixing member 7. Push the limit back plate 5 through the telescopic rod 4 to make it fit with the end face of the hub bearing 14. This step ensures the stability of the bearing in the axial direction and prevents it from moving during the processing. Install the rivet on the rivet head 11 of the rivet disc 10. Ensure that the position and number of the rivets meet the processing requirements. Start the cylinder on the rivet mounting table 3 to make the rivet disc 10 close to the flange end face of the hub bearing 14. Then, drive the rivet head 11 to rotate through the drive motor 13 to drive the rivet into the rivet hole of the flange. After the rivet assembly is completed, the cylinder returns the rivet disc 10 to its original position. Check whether the rivet is firmly installed and whether the hub bearing 14 is intact. If everything is normal, turn off the riveting machine, remove the fixed hub bearing 14, and prepare for the next round of processing.

[0024] The rotary riveting machine adopts automated control, which can quickly and accurately complete the clamping and rivet assembly of the wheel hub bearing 14, greatly improving the processing efficiency. Through the precise clamping and limit system, the stability of the wheel hub bearing 14 during the processing is ensured, thereby ensuring the precise installation of the rivet and the processing quality of the bearing. The design of the rotary riveting machine takes into account the convenience of the operator. The entire processing process can be completed through simple control, reducing the difficulty of operation. The rotary riveting machine is suitable for the processing of wheel hub bearings 14 of different specifications and models. By adjusting the relevant parameters of the clamping table 6 and the rivet installation table 3, it can easily adapt to different processing requirements. The various components of the rotary riveting machine are carefully designed and manufactured to ensure its safety and reliability during the working process.

[0025] At the same time, through reasonable maintenance and care, the service life of the equipment can be extended.

[0026] The fixing member 7 is provided with a triangular clamping groove, and the inclination angle of the triangular inclined surface of the triangular clamping groove is greater than the inclination angle of the triangular inclined surface of the triangular bracket.

[0027] A triangular clamping groove is provided on the fixing member 7, and the inclination angle of the triangular inclined surface of the triangular clamping groove is made greater than the inclination angle of the triangular inclined surface of the triangular bracket, so that the wheel hub bearing 14 can be more stable during the clamping process, because a larger inclination angle can generate a greater clamping force, effectively preventing the bearing from sliding or shifting during the processing. Secondly, a larger inclination angle also helps to quickly locate the wheel hub bearing 14 and improve processing efficiency. In addition, this design also simplifies the operation process, because the operator can more easily observe the placement of the bearing, thereby ensuring that the bearing can be accurately placed in the correct position every time.

[0028] The rivet mounting platform 3 is provided with a cylinder mounting cavity, and the connecting shaft is connected to the cylinder driving shaft arranged in the cylinder mounting cavity. The automatic feeding and retraction of the rivet disc 10 is realized, and the production efficiency is improved. The precise control and rapid response of the cylinder enable the rivet disc 10 to quickly approach or move away from the flange end face of the hub bearing 14, thereby speeding up the entire rivet assembly process. The installation and maintenance of the cylinder are relatively simple. Since the cylinder mounting cavity is located inside the rivet mounting platform 3, the arrangement and connection of the cylinder are more compact and neat, reducing external interference and potential failure points. The use of the cylinder also provides greater force output, ensuring the stability and reliability of the rivet disc 10 during the feeding process. This is crucial to ensure the accuracy and quality of rivet assembly.

[0029] The rotary rivet head 11 is installed through a rivet clamp 12 arranged on the rivet disk 10 . The rotary rivet head is connected to a driving motor 13 . There are at least three rotary rivet heads, which are equidistantly distributed in the circumferential direction of the rivet disk 10 .

[0030] The rivet head 11 is mounted on the rivet disc 10 through the rivet clamp 12. This design allows the rivet head to be quickly and accurately mounted on the rivet clamp 12. Since the rivet head is connected to the drive motor 13, the drive motor 13 can start quickly and drive the rivet head 11 to rotate, so as to efficiently drive the rivet into the flange rivet hole of the hub bearing 14. The number of rivet heads is at least three, and they are evenly distributed in the circumferential direction of the rivet disc 10. This uniform distribution ensures that each rivet can obtain the same pressure and rotation speed when driving, thereby ensuring that each rivet can be evenly fixed on the flange, improving the overall stability and reliability of the hub bearing 14. Since the rivet head is mounted on the rivet disc 10 through the rivet clamp 12, the number of rivet heads can be conveniently increased or decreased as needed. This flexibility enables the rivet machine to adapt to the processing of hub bearings 14 of different specifications and requirements, and improves the versatility and adaptability of the equipment. The modular design of the rivet head and the rivet clamp 12 allows them to be quickly replaced when worn or damaged. At the same time, since the rotary rivet head is mounted on the rivet disc 10 through the rivet clamping claws 12, this structure also makes the replacement process simple and convenient, reducing maintenance costs and time.

[0031] Working principle: first, manually place the wheel hub bearing 14 in the triangular bracket of the clamping table 6, control the driver 9 to drive the screw 8 to rotate so that the fixing part 7 moves downward, and clamp the wheel hub bearing 14 through the triangular clamping groove and the triangular bracket. Before clamping, ensure that there is a gap greater than the length of the rivet between the flange end face of the wheel hub bearing 14 and the surface of the clamping table 6. After fixing the wheel hub bearing 14, drive the telescopic rod 4 to push the limiting back plate 5 to fit with the end face of the wheel hub bearing 14 to complete the axial limiting of the wheel hub bearing 14. After the axial limiting is completed, drive the rivet disc 10 to feed and approach the flange end face of the wheel hub bearing 14. Drive the rivet jaw 12 to rotate through the drive motor 13, and drive the rivet head on the rivet jaw 12 into the rivet hole of the flange to complete the assembly of the rivet.
