Description

Technical Field

[0001] This utility model provides a stepped stamping device for motorcycle bearing assembly, belonging to the field of bearing assembly processing technology. Background Technology

[0002] Bearings are components that fix and reduce the coefficient of friction during mechanical transmission. In other words, when other machine parts move relative to each other on a shaft, they reduce the coefficient of friction during power transmission and maintain the shaft's central position. Bearings are crucial components in modern mechanical equipment. Motorcycle bearings are key rotating components in motorcycles, and their assembly quality directly affects the motorcycle's riding safety and overall performance. In the motorcycle component assembly process, assembly stamping is a critical step, requiring the motorcycle bearings to be press-fitted into bearing housings. Currently, bearing assembly stamping devices are generally used.

[0003] Existing motorcycle bearing assembly stamping devices can basically meet normal usage needs, but they still have certain drawbacks: they typically employ single-station operation, meaning the operator manually places the bearing to be assembled into the stamping die, completes one stamping cycle, and then manually removes the finished product before repeating the process. This one-time placement, one-stamping, one-removal mode leads to relatively inefficient process connections. Furthermore, the accuracy of positioning when manually placing the bearing and bearing housing highly depends on the operator's skill and experience; even slight positional deviations can cause uneven force distribution during stamping, resulting in inaccurate and unreliable positioning. Operators must repeatedly fine-tune the placement of the motorcycle bearings during assembly, compromising product quality and slowing down the overall production cycle, making continuous stepped operation difficult and leading to low overall production efficiency. Therefore, this utility model provides a stepped stamping device for motorcycle bearing assemblies. Utility Model Content

[0004] The technical problem solved by this utility model is that the positioning is not accurate and reliable enough, requiring workers to repeatedly fine-tune the placement of the motorcycle bearing assembly, which cannot guarantee product quality, slows down the overall production cycle, makes it difficult to achieve continuous step-by-step operation, and results in low overall production efficiency.

[0005] To solve the technical problem, the technical solution provided by this utility model is: a stepped stamping device for motorcycle bearing assembly, including a base, and further comprising:

[0006] A bearing conveying assembly includes a turntable rotatably connected to the top of a base. The top circumference of the turntable is provided with a plurality of storage slots. A limiting rod is provided at the center of the bottom of each storage slot. A bearing clamp for positioning the bearing is provided on the outside of the storage slot.

[0007] A stamping assembly is provided on one side of the turntable. The stamping assembly includes an L-shaped support plate. An electric push rod is provided on the top of the L-shaped support plate. The telescopic rod end of the electric push rod is provided with a stamping head placed above the storage slot.

[0008] Furthermore, the bearing fixture includes upright plates symmetrically located on both sides of the storage slot and fixedly mounted on the top of the turntable. Damping springs are provided on the side walls of the upright plates that are close to each other, and the ends of the damping springs are provided with V-shaped clamps that are slidably connected to the top of the turntable.

[0009] Furthermore, the top of the turntable is provided with a limiting rail that matches the bottom of the V-shaped clamp.

[0010] Furthermore, a motor is provided at the bottom of the base, and the output end of the motor is fixedly connected to the center of the bottom of the turntable.

[0011] Furthermore, the L-shaped support plate is fixedly installed on the top of the base and placed on the side of the turntable, and the side wall of the L-shaped support plate is provided with a reinforcing plate that is fixedly connected to the top of the base.

[0012] Furthermore, the bottom of the stamping head is provided with a recessed hole for the limiting rod to pass through.

[0013] The beneficial effects of this utility model are:

[0014] This device, through the combined action of bearing conveying components, bearing fixtures, and stamping components, integrates processes such as loading, indexing, stamping, indexing, and unloading into one unit. Operators only need to load and unload materials at designated workstations, while the stamping process is completed automatically by the equipment. With the assistance of bearing fixtures and limit rods, it achieves unique dual precision positioning, ensuring accurate and reliable positioning. This eliminates the need for operators to repeatedly fine-tune the placement of motorcycle bearing assemblies, effectively guaranteeing product quality. It enables continuous stepped operation, greatly shortens the single-piece production cycle, and improves overall production efficiency. Attached Figure Description

[0022] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0023] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] According to the appendix Figure 1 , 2 As shown in Figure 4, this utility model provides a stepped stamping device for motorcycle bearing assembly: it includes a base 1, which provides an installation reference and support for the entire device, and a bearing conveying assembly 2. The bearing conveying assembly 2 includes a turntable 3 rotatably connected to the top of the base 1. The top circumference of the turntable 3 is provided with several storage slots 4, such as 6 or 8. The bottom center of the storage slot 4 is provided with a limiting rod 5. The bottom of the base 1 is provided with a motor 15. The output end of the motor 15 is fixedly connected to the bottom center of the turntable 3. Specifically, the motorcycle bearing seat and the bearing are placed in the storage slot 4 in sequence. The center hole of the bearing seat and the bearing is limited by the limiting rod 5. By starting the motor 15, the turntable 3 is driven to rotate intermittently to realize the automatic switching of the work position, thereby driving the motorcycle bearing placed in the storage slot 4 to rotate intermittently.

[0025] As per the instruction manual Figure 2 , 4As shown: It also includes a stamping assembly 7 set on one side of the turntable 3. The stamping assembly 7 includes an L-shaped support plate 8 fixedly set on the top of the base 1 and placed on the side of the turntable 3. The side wall of the L-shaped support plate 8 is provided with a reinforcing plate 16 fixedly connected to the top of the base 1 to strengthen the fixation. The top of the L-shaped support plate 8 is provided with an electric push rod 9. The electric push rod 9 is used as a power source and can be a servo electric cylinder or a stepper electric cylinder to precisely control the stroke, speed and pressure of the stamping. The telescopic rod end of the electric push rod 9 is provided with a stamping head 10 placed above the storage slot 4. The shape and size of the stamping head 10 are designed according to the specifications of the specific bearing to ensure that it can make good contact with the bearing or the part that needs to be pressed. The bottom of the stamping head 10 is provided with a concave hole 17 for the limit rod 5 to pass through. Specifically, when the electric push rod 9 is started, the stamping head 10 is moved up and down. The concave hole 17 can prevent the stamping head 10 from interfering with the limit rod 5 during the pressing process, ensuring that the stamping force can be accurately applied to the bearing itself.

[0026] As per the instruction manual Figure 1 , 3 As shown: The outer side of the storage slot 4 is provided with a bearing clamp 6 for positioning the bearing. The bearing clamp 6 includes upright plates 11 symmetrically located on both sides of the storage slot 4 and fixedly installed on the top of the turntable 3. The side walls of the upright plates 11 that are close to each other are provided with damping springs 12. The ends of the damping springs 12 are provided with V-shaped clamps 13 that are slidably connected to the top of the turntable 3. The top of the turntable 3 is provided with a limiting rail 14 that matches the bottom of the V-shaped clamps 13, which serves to limit the V-shaped clamps 13 and ensure the sliding stability and guidance of the V-shaped clamps 13 during clamping and loosening. Specifically, when the bearing seat is placed, the two V-shaped clamps 13 will be pushed open, causing them to slide outward against the spring force. Subsequently, under the action of the rebound force of the damping springs 12, the two V-shaped clamps 13 will tightly clamp the outer wall of the bearing seat from both sides. The V-shaped groove design of the V-shaped clamps allows the clamping force to automatically push the bearing seat towards the center, achieving precise secondary centering and firm clamping.

[0027] The control method of this utility model is through a programmable logic controller. The controller adopts existing mature technology, which is not shown in the figure and will not be described in detail here. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0028] The principle of this utility model

[0029] The workflow follows a cyclical pattern of loading, indexing, stamping, indexing, and unloading. The specific steps are as follows:

[0030] Loading and positioning: The operator places the motorcycle bearing and bearing housing to be assembled and stamped at the designated loading station. The bearing housing is first positioned by the inner hole of the limiting rod 5, and then automatically clamped and centered by the V-shaped clamps 13 on both sides. After that, the bearing is placed through the limiting rod 5.

[0031] Indexing: After the loading is completed, the controller starts the motor 15, and the motor 15 drives the turntable 3 to rotate in a step-like manner at a preset angle (such as 60° or 45°). This rotation rotates the station that has just been loaded to the stamping station directly below the stamping head 10. At the same time, the station that has completed the stamping is rotated to the unloading station, and a new empty material tray 4 is rotated to the loading station.

[0032] Stamping: When the turntable 3 rotates to the position and stops, the controller starts the electric push rod 9. The telescopic rod of the electric push rod 9 extends downward, driving the stamping head 10 to descend and apply the set pressure to the bearing located at the stamping station to complete the stamping assembly of the combined bearing and bearing seat. During this process, the concave hole 17 accommodates the limiting rod 5.

[0033] Reset: After stamping is completed, the electric push rod 9 moves in the opposite direction, driving the stamping head 10 to rise and reset, disengaging from the bearing;

[0034] Cycle: When a stamping cycle ends, the controller restarts motor 15, causing turntable 3 to rotate again, sending the stamped finished product to the unloading station, and at the same time sending the next bearing to be processed into the stamping station. The operator can take the finished product from the unloading station and put the new workpiece into the loading station while the equipment is running. This cycle is repeated to achieve efficient continuous production.

[0035] In summary, this device, through the combined action of the bearing conveying assembly, bearing fixture, and stamping assembly, integrates the processes of loading, indexing, stamping, indexing, and unloading into one unit. Operators only need to load and unload materials at designated workstations, while the stamping process is completed automatically by the equipment. This achieves continuous, stepped operation, greatly shortening the production cycle of a single piece and improving overall production efficiency. Furthermore, the bearing fixture 6 and limit rod enable unique dual precision positioning, ensuring accurate and reliable positioning. This eliminates the need for operators to repeatedly fine-tune the placement of motorcycle bearing assemblies, effectively guaranteeing product quality.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
