Technical Field
[0001] The invention relates to the technical field of bearing riveting, in particular to an extrusion riveting device and a riveting method for a bearing retainer. Background Art
[0002] In the field of mechanical manufacturing, bearings are key components widely used in various rotating equipment. As an important component of bearings, bearing cages play the role of separating and fixing rolling elements, and their quality directly affects the performance and service life of bearings. With the development of modern industry, the requirements for the accuracy, strength and reliability of bearings are getting higher and higher. Therefore, an efficient and accurate bearing cage manufacturing process is needed; When the traditional extrusion riveting device is used to process the bearing cage, it may cause the bearing cage to be easily displaced and shake during the riveting process due to the lack of accurate positioning mechanism or insufficient positioning mechanism accuracy. This will make the riveting point position inaccurate, affect the structural accuracy of the bearing cage, and thus reduce the performance of the bearing; Some existing devices have poor adaptability to bearing cages of different specifications. During the production process, when it is necessary to process bearing cages of various sizes, it may be necessary to frequently change molds or adjust equipment parameters, which not only increases production costs but also reduces production efficiency; During the extrusion riveting process, the bearing retainer is easily damaged due to the high riveting pressure. However, some existing devices do not have an effective buffer mechanism and cannot provide buffer protection for the bearing retainer and the device itself during the riveting process, resulting in a high defective rate of the product, while also accelerating the wear of the device and shortening the service life of the equipment.

[0008] As a further solution of the present invention: a fixed rack is fixedly connected to a surface of one side of the sliding platform, and the fixed rack and the transmission wheel are meshed with each other.
[0009] As a further solution of the present invention: the auxiliary mechanism includes a fixed block, a transmission frame, an adjustment plate, an auxiliary wheel and a rotating wheel, the second fixed rod is fixedly connected to the rotating wheel on the side away from the second synchronous wheel, and the fixed block is symmetrically arranged on the upper side of the fixed frame, the fixed frame is fixedly connected to the transmission frame through the fixed block, the transmission frame is movably connected with an adjustment plate, one side of the adjustment plate is a rack structure, and the gears between the adjustment plate and the rotating wheel are meshed with each other.
[0010] As a further solution of the present invention: the buffer mechanism includes a positioning rod, a placement plate, a buffer spring, a limit groove, a limit block and a buffer rod, a limit groove is opened on the upper side of the fixed frame, a buffer rod is slidably connected inside the limit groove, the buffer rod is symmetrically provided with a limit block in the limit groove, the buffer rod passes through the limit groove and is provided with a placement plate, the upper side of the placement plate is fixedly connected with the positioning rod, and a buffer spring is sleeved on the buffer rod between the placement plate and the fixed frame.
[0011] As a further solution of the present invention: a bearing holder is arranged on the placement plate, and an auxiliary wheel is movably connected to a side of the adjustment plate away from the adjustment holder, and the bearing holder cooperates with the auxiliary wheel and the riveting workbench.
[0012] An extrusion riveting method for a bearing retainer comprises the following steps: S1: Start the telescopic cylinder of the sliding mechanism to shrink it, drive the transmission plate to move backward, and then make the sliding table slide backward along the slide rail, move the riveting workbench to the initial position away from other working parts, so that the subsequent placement of the bearing cage can proceed smoothly, and also leave space for the action of other mechanisms; S2: Start the telescopic cylinder to drive the sliding table and the riveting workbench to move forward, and move the placement plate with the bearing retainer to the riveting work area. During the movement, the transmission wheel of the limit mechanism continues to rotate, driving the limit plate to move along the predetermined trajectory, and accurately limit the bearing retainer to prevent it from displacement or shaking during the transfer process. When it moves to the predetermined position, the bearing retainer is in the precise position between the riveting workbench and the auxiliary wheel, ready for extrusion riveting operation; S3: Start the riveting power source of the extrusion riveting device to perform an extrusion riveting operation on the bearing cage that is located between the riveting workbench and the auxiliary wheel and is precisely limited. During the riveting process, the buffer spring of the buffer mechanism begins to play a role to prevent the bearing cage from being damaged or deformed due to sudden large external force; S4: When the extrusion riveting operation is completed, the telescopic cylinder contracts again, driving the riveting workbench and the bearing retainer on the placement plate that has been riveted back to the initial position, so that the finished product can be taken out and the next processing cycle can be carried out.
[0013] Compared with the prior art, the present invention has the following beneficial effects: When the sliding table starts to move along the slide rail under the drive of the telescopic cylinder, the fixed rack on one side of the sliding table engages with the transmission wheel, and the movement of the sliding table drives the transmission wheel to rotate. When the transmission wheel rotates, the guide block fixed on its upper side moves in the guide groove on the upper side of the fixed frame. The guide groove limits the guide block to move only along a specific trajectory, thereby ensuring that the transmission wheel rotates stably without displacement deviation. At the same time, it also enables the limit plate connected to the guide block to move in a predetermined direction and trajectory, thereby positioning the bearing retainer. During the riveting process, through the meshing of the transmission wheel and the fixed rack and the transmission of the synchronous belt, the limit plate can be moved to the appropriate position in time, and the bearing retainer can be accurately limited to prevent it from displacement or shaking during riveting, thereby ensuring the riveting quality and accuracy. During the rotation of the transmission wheel, the lower side thereof is connected with the first synchronous wheel through the first fixed rod, and the first synchronous wheel is connected with the second synchronous wheel on the second fixed rod through a synchronous belt. Therefore, when the first synchronous wheel rotates with the transmission wheel, the second synchronous wheel will be driven to rotate synchronously through the synchronous belt. This synchronous rotation design can realize the coordinated movement of multiple axes. The rotation of the second synchronous wheel is used in the auxiliary mechanism to realize the linkage operation of related components, so as to cooperate with the entire device to accurately limit and position the bearing retainer and perform other related processes; When the second fixing rod in the limiting mechanism rotates with the transmission of the synchronous belt, the rotating wheel connected to the second fixing rod will also rotate synchronously. Since the rotating wheel is meshed with the rack structure on one side of the adjusting plate, the rotation of the rotating wheel will drive the adjusting plate to rotate on the transmission frame. An auxiliary wheel is movably connected to the side of the adjusting plate away from the transmission frame. When the adjusting plate moves, the auxiliary wheel will move synchronously therewith. During the extrusion and riveting process of the bearing retainer, the auxiliary wheel can play an auxiliary supporting, positioning or adjusting role for the bearing retainer according to the position change of the adjusting plate. When riveting bearing retainers of different specifications, the rotating wheel is driven to rotate through the transmission of the limiting mechanism, and then the adjusting plate is moved, thereby adjusting the position of the auxiliary wheel so that it can better fit the surface of the bearing retainer, thereby ensuring the stability and accuracy of the bearing retainer during the riveting process, working in coordination with the riveting workbench to improve the quality and effect of riveting, and also enhancing the adaptability of the entire device to bearing retainers of different specifications.
[0014] In the initial state, the buffer spring is in a certain pre-compression or natural extension state, so that the placement plate and the bearing retainer located thereon are in a relatively stable initial position. When the extrusion riveting operation is performed, if an external force acts on the bearing retainer, the placement plate will be subjected to force together with the bearing retainer. Since the placement plate is connected to the fixing frame through a buffer rod, and a buffer spring is sleeved on the buffer rod, the placement plate will slide in the limit groove along the buffer rod. During the sliding process, the buffer spring will be further compressed or stretched, and the buffer spring will generate an elastic force in the opposite direction of the external force. This elastic force acts on the placement plate, thereby buffering and shock-absorbing the external force exerted on the bearing retainer, avoiding damage or deformation of the bearing retainer due to sudden large external force, and at the same time reducing the impact of vibration caused by external force impact on other components of the entire device, ensuring the stability and reliability of the device operation, providing protection in terms of force buffering, and jointly ensuring that the bearing retainer can successfully complete the extrusion riveting operation and the quality meets the requirements.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1
[0024] Reference Figure 1-Figure 3This embodiment provides an extrusion riveting device and a riveting method for a bearing retainer, comprising a base 1, a sliding mechanism 2, a limiting mechanism 3, a mounting groove 4, an auxiliary mechanism 6 and a buffer mechanism 7. The base 1 is provided with a mounting groove 4, the mounting groove 4 is provided with a sliding mechanism 2, and the middle of the mounting groove 4 is provided with a gear-driven limiting mechanism 3, and the upper side of the limiting mechanism 3 is provided with a buffer mechanism 7, and the side of the mounting groove 4 close to the limiting mechanism 3 is provided with an auxiliary mechanism 6; In this embodiment, specifically, the sliding mechanism 2 includes a telescopic cylinder 201, a transmission plate 202, a slide rail 203, a sliding table 204 and a riveting workbench 205. The telescopic cylinder 201 is fixedly connected to one side of the base 1, and the slide rail 203 is symmetrically arranged inside the mounting groove 4. The sliding table 204 is slidably connected to the slide rail 203. The riveting workbench 205 is arranged on the upper side of the sliding table 204, and the transmission plate 202 is fixedly connected to one side of the sliding table 204. The output end of the telescopic cylinder 201 is fixedly connected to the transmission plate 202; When the device starts to run, the telescopic cylinder 201 receives the control signal and starts, and the output end of the telescopic cylinder 201 starts to telescope. Since it is fixedly connected to the transmission plate 202, the transmission plate 202 moves linearly in the horizontal direction with the action of the telescopic cylinder 201, and the sliding table 204 cooperates with the slide rails 203 symmetrically arranged in the installation groove 4. With the movement of the sliding table 204, the sliding riveting workbench 205 will also move synchronously; In the initial state, the riveting table 205 may be in a position far away from other working parts. When the extrusion riveting operation of the bearing retainer is required, the telescopic cylinder 201 extends, pushes the transmission plate 202 to drive the sliding table 204 and the riveting table 205 to move to the area where the limiting mechanism 3 and the auxiliary mechanism 6 are located, so that the bearing retainer can accurately enter the riveting work area and cooperate with other mechanisms to complete the extrusion riveting action. When a riveting operation is completed, the telescopic cylinder 201 retracts, driving the riveting table 205 back to the initial position or other specified position for the next processing cycle. Example 2
[0025] Reference Figure 3-Figure 5, this embodiment is based on the previous embodiment, and is different from the previous embodiment in that the limiting mechanism 3 includes a fixing frame 301, a transmission wheel 302, a guide groove 303, a guide block 304, a fixed rack 305, a first fixing rod 306, a first synchronous wheel 307, a synchronous belt 308, a second synchronous wheel 309 and a second fixing rod 310, a fixing frame 301 is fixedly connected to the middle of the installation groove 4, the transmission wheel 302 is movably connected inside the fixing frame 301, and a guide groove 303 is opened on the upper side surface of the fixing frame 301, a guide block 304 is fixedly connected to the upper side of the transmission wheel 302, the guide block 304 is located in the guide groove 303, and a limiting plate 311 is provided on the side of the guide block 304 away from the transmission wheel 302; A first fixing rod 306 is provided at the lower side of the transmission wheel 302 in the fixing frame 301, a first synchronous wheel 307 is provided at the side of the first fixing rod 306 away from the transmission wheel 302, a second fixing rod 310 is provided at one side of the fixing frame 301, a second synchronous wheel 309 is provided at one side of the second fixing rod 310, and a synchronous belt 308 is sleeved between the first synchronous wheel 307 and the second synchronous wheel 309; A fixed rack 305 is fixedly connected to one side surface of the sliding platform 204, and the fixed rack 305 and the transmission wheel 302 are meshed with each other; When the sliding table 204 starts to move along the slide rail 203 under the drive of the telescopic cylinder 201, the fixed rack 305 on one side of the sliding table 204 meshes with the transmission wheel 302, and the movement of the sliding table 204 will drive the transmission wheel 302 to rotate. When the transmission wheel 302 rotates, the guide block 304 fixed on its upper side will move in the guide groove 303 on the upper side of the fixed frame 301. The guide groove 303 limits the guide block 304 to move only along a specific trajectory, thereby ensuring that the transmission wheel 302 rotates stably without displacement deviation, and also enables the limit plate 311 connected to the guide block 304 to move in a predetermined direction and trajectory, so as to position the bearing holder 5. During the riveting process, through the meshing of the transmission wheel 302 and the fixed rack 305 and the transmission of the synchronous belt 308, the limit plate 311 can be moved to the appropriate position in time, and the bearing holder is accurately limited to prevent it from displacement or shaking during riveting, thereby ensuring the riveting quality and accuracy. During the rotation of the transmission wheel 302, the lower side thereof is connected to the first synchronous wheel 307 via the first fixed rod 306, and the first synchronous wheel 307 is connected to the second synchronous wheel 309 on the second fixed rod 310 via a synchronous belt 308. Therefore, when the first synchronous wheel 307 rotates with the transmission wheel 302, the second synchronous wheel 309 is driven to rotate synchronously via the synchronous belt 308. This synchronous rotation design can realize the coordinated movement of multiple axes. The rotation of the second synchronous wheel 309 is used in the auxiliary mechanism to realize the linkage operation of related components, so as to cooperate with the entire device to accurately limit and position the bearing retainer and perform other related processes. Example 3
[0026] Reference Figure 5 and Figure 6 , this embodiment is based on the previous embodiment, and is different from the previous embodiment in that the auxiliary mechanism 6 includes a fixed block 601, a transmission frame 602, an adjustment plate 603, an auxiliary wheel 604 and a rotating wheel 605, a side of the second fixed rod 310 away from the second synchronous wheel 309 is fixedly connected with the rotating wheel 605, and a fixed block 601 is symmetrically arranged on the upper side of the fixed frame 301, the fixed frame 301 is fixedly connected with the transmission frame 602 through the fixed block 601, and the transmission frame 602 is movably connected with an adjustment plate 603, one side of the adjustment plate 603 is a rack structure, and the gears between the adjustment plate 603 and the rotating wheel 605 are meshed with each other; When the second fixing rod 310 in the limiting mechanism rotates with the transmission of the synchronous belt 308, the rotating wheel 605 connected to the second fixing rod 310 will also rotate synchronously. Since the rotating wheel 605 is meshed with the rack structure on one side of the adjusting plate 603, the rotation of the rotating wheel 605 will drive the adjusting plate 603 to rotate on the transmission frame 602. An auxiliary wheel 604 is movably connected to the side of the adjusting plate 603 away from the transmission frame 602. When the adjusting plate 603 moves, the auxiliary wheel 604 will move synchronously therewith. During the extrusion and riveting process of the bearing retainer 5, the auxiliary wheel 604 The bearing retainer 5 can be provided with auxiliary support, positioning or adjustment according to the position change of the adjustment plate 603. When bearing retainers of different specifications are riveted, the rotating wheel 605 is driven to rotate through the transmission of the limit mechanism 3, and then the adjustment plate 603 is moved, so as to adjust the position of the auxiliary wheel 604 so that it can better fit the surface of the bearing retainer, ensure the stability and accuracy of the bearing retainer during the riveting process, work together with the riveting workbench 205, improve the quality and effect of riveting, and also enhance the adaptability of the entire device to bearing retainers of different specifications. Example 4
[0027] Reference Figure 7This embodiment is based on the previous embodiment, and is different from the previous embodiment in that the buffer mechanism 7 includes a positioning rod 701, a placement plate 702, a buffer spring 703, a limiting groove 704, a limiting block 705 and a buffer rod 706. A limiting groove 704 is provided on the upper side of the fixing frame 301, and a buffer rod 706 is slidably connected inside the limiting groove 704. The buffer rod 706 is symmetrically provided with a limiting block 705 in the limiting groove 704. The buffer rod 706 passes through the limiting groove 704 and is provided with a placement plate 702. The positioning rod 701 is fixedly connected to the upper side of the placement plate 702. A buffer spring 703 is sleeved on the buffer rod 706 between the placement plate 702 and the fixing frame 301; The placing plate 702 is provided with a bearing holder 5, and the side of the adjusting plate 603 away from the adjusting holder is movably connected with an auxiliary wheel 604, and the bearing holder 5 cooperates with the auxiliary wheel 604 and the riveting workbench 205; In the initial state, the buffer spring 703 is in a certain pre-compression or natural extension state, so that the placement plate 702 and the bearing retainer 5 located thereon are in a relatively stable initial position. When the extrusion riveting operation is performed, if an external force acts on the bearing retainer 5, the placement plate 702 will be subjected to force together with the bearing retainer 5. Since the placement plate 702 is connected to the fixing frame 301 through the buffer rod 706, and the buffer spring 703 is sleeved on the buffer rod 706, the placement plate 702 will slide in the limiting groove 704 along the buffer rod 706. During the sliding process, the buffer spring 703 will be further compressed or stretched, and the buffer spring will generate an elastic force in the opposite direction to the external force. This elastic force acts on the placement plate 702, thereby buffering and reducing the external force on the bearing retainer 5, preventing the bearing retainer 5 from being damaged or deformed due to sudden large external force. At the same time, it can also reduce the impact of vibration caused by external force impact on other parts of the entire device, ensure the stability and reliability of the device operation, provide protection in force buffering, and jointly ensure that the bearing retainer 5 can successfully complete the extrusion riveting operation and the quality meets the requirements.
