Description

Technical Field

[0001] The invention relates to an isothermal buffer device for inner and outer rings of a bearing. Background Art

[0002] The automated production process of small bearings mainly includes grinding, cleaning and assembly, sealing and lubrication, quality inspection and other links. In order to improve production efficiency, these processes are usually connected in series through automated wiring. In the production of small deep groove ball bearings, after the inner and outer rings are ground, a large amount of impurities will adhere to the surface, which must be removed by ultrasonic cleaning in order to perform inner and outer diameter inspection and groove inspection. These inspection steps are designed to eliminate defective inner and outer diameter products and obtain accurate groove data to provide a basis for subsequent rolling element assembly.

[0003] However, during the operation of the ultrasonic cleaning machine, the continuous vibration of the oscillator will generate a large amount of heat, causing the temperature of the cleaning oil to be significantly higher than the ambient temperature of the assembly workshop. The overheated bearing components will not be able to be fully cooled before measurement due to insufficient cooling time of the inner and outer rings after cleaning. This will cause deviations in the detection values, thereby reducing the measurement accuracy and prolonging the repeated measurement time, ultimately affecting the overall efficiency of the production line. At the same time, there is a lack of effective centralized caching sites in the existing locations. In addition, the close coordination between the various processes of the automated assembly line means that once a process equipment fails, the entire production line will stagnate, making the entire production line less resistant to faults.

[0004] Therefore, there is an urgent need for a device that can meet the rhythm of automated bearing production, achieve bearing temperature control, and cache a large number of bearing inner and outer rings. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an isothermal caching device for inner and outer rings of a bearing, which has a simple structure, can effectively achieve caching for the inner and outer rings of the bearing, has high automation, and has good use effect.

[0006] To achieve the above-mentioned purpose, the present invention provides an isothermal caching device for inner and outer rings of a bearing, comprising at least two storage racks for storing inner rings and outer rings respectively, a receiving mechanism for connecting an ultrasonic cleaning device, and a transfer mechanism for sending the inner ring or the outer ring from the receiving mechanism to the storage rack, wherein the storage rack is provided with a placement groove for accommodating the inner ring or the outer ring, the receiving mechanism comprises a receiving seat, a traction motor, a lifting motor and a pushing motor, the traction seat comprises a longitudinal material channel, a transverse material channel and a lifting material channel connected in sequence, the traction motor is arranged on the longitudinal material channel and connected with a conveyor belt, the pushing motor is arranged at a position corresponding to the transverse material channel, the lifting material channel is provided with a connected feed trough, a material running trough and a material discharging trough, the feed trough is arranged close to the transverse material channel, the connecting end of the material running trough and the material discharging trough is shorter than the connecting end of the material running trough and the feed trough, the lifting motor is arranged on the bottom surface of the material discharging trough, the output end of the lifting motor is connected with a lifting piece, the lifting piece is slidably matched with the material discharging trough, and the transfer mechanism is arranged between the material discharging trough and the placement trough.

[0007] The beneficial effect of this arrangement is as follows: first, on the longitudinal material channel of the receiving seat, the traction motor drives the conveyor belt to operate, and receives the cleaned inner and outer rings at a stable and efficient speed, and quickly transports them to the horizontal material channel direction. This process not only realizes the initial transfer of materials, but also ensures the stability of the transportation process. During transportation, the conveyor belt runs at a uniform and stable speed, and the precise regulation of the traction motor is used to avoid any shaking of the materials. This design effectively avoids the collision and friction between the inner and outer rings caused by shaking, eliminates damage, and ensures their surface quality and dimensional accuracy. Then, the push-up motor performs a push-up operation corresponding to the horizontal material channel position, pushing the material to the feed trough of the lifting material channel. The feed trough, the feed trough and the discharge trough are interconnected, and the connecting end of the feed trough and the discharge trough is shorter than the connecting end of the feed trough and the feed trough. This inclined design allows the material to slide smoothly from the feed trough to the discharge trough position with the assistance of gravity. During this period, the lifting motor is on standby at the bottom of the discharge chute. Once the material reaches the discharge chute, the lifting part connected to the output end of the lifting motor starts immediately, cooperating with the sliding of the discharge chute to steadily lift the bearing ring body, so that it is exposed under the transfer mechanism in an ideal vertical shape. The transfer mechanism responds quickly at this time, grabs the ring body and sends it into the placement slot of the storage rack, realizing efficient caching of materials. This caching method not only ensures the stability of the material during the caching process and reduces the risk of collision, but also greatly improves the efficiency of material transfer and caching through the coordinated operation of various mechanisms, providing a stable and orderly material supply for subsequent production processes, and effectively improving the operating efficiency of the entire production system. At the same time, through this isothermal caching device, while realizing efficient material transfer and storage, the material temperature is also accurately controlled. The bearing continuously exchanges heat with the environment in a constant temperature field, thanks to the precise control of the waiting time of a single material by the device, ensuring that each material is at room temperature when it flows out. In subsequent processes such as bearing size measurement, temperature consistency effectively eliminates the interference of thermal expansion and contraction on measurement data, ensures measurement accuracy, greatly improves the reliability of product inspection data, avoids misjudgment or rework due to temperature factors, and comprehensively optimizes the production process to provide guarantees for the production of high-quality bearings.

[0008] As a further configuration of the present invention, the lifting channel is arranged in parallel with the longitudinal channel, and a guiding slope is arranged between the feeding trough of the lifting channel and the transverse channel for guiding the outer ring or the inner ring to enter the feeding trough in a vertical state.

[0009] The beneficial effect of this arrangement is that when the bearing ring body coming from the horizontal material channel contacts the guide slope, its unique tilt angle can guide the ring body to gradually adjust its posture. At the same time, the size of the feed trough is adapted to the size of the rectangular projection of the bearing ring body on the vertical plane. This ensures that the ring body can be accurately positioned in a vertical state when sliding down the guide slope into the feed trough. The ring body vertically enters the lifting channel, laying a solid foundation for the efficient operation of the subsequent lifting motor and transfer mechanism, greatly improving the smoothness and accuracy of the overall device operation.

[0010] As a further configuration of the present invention, the lifting member is configured in a V-shape, and support grooves are provided on two arms of the lifting member.

[0011] The beneficial effect of this arrangement is that when the lifting piece is working, the two V-shaped arms can embrace the ring from both sides, effectively preventing the ring from shaking in the vertical direction. The support grooves on the arms are highly consistent with the outer contour of the ring, further increasing the contact area between the lifting piece and the ring, greatly improving the friction, allowing the ring to be firmly fixed during the lifting process, providing a reliable basic guarantee for subsequent transfer operations.

[0012] As a further configuration of the present invention, the placement groove includes a high part and a low part, the high part and the bottom are connected by a smooth inclined surface, the placement groove includes a fixed wall and an adjustment wall, the adjustment wall is slidably matched with the storage rack, and the adjustment wall is provided with a fastener for fastening the adjustment wall.

[0013] The beneficial effect of this arrangement is that the high part and the low part are connected by a smooth slope, which provides a natural transition for the placement of the ring body and reduces the risk of collision during placement. The placement groove is composed of a fixed wall and an adjustment wall, and the adjustment wall and the storage rack slide together. This ingenious structure makes it possible to adapt to ring bodies of different widths. In bearing production, there are many specifications of ring body widths, and traditional storage devices are difficult to take into account. However, this device can easily cope with it. When it is necessary to place ring bodies of different widths, just loosen the fasteners on the adjustment wall, and the adjustment wall can be easily slid to flexibly change the width of the placement groove. It not only meets the caching requirements of different types of bearing ring bodies, but also avoids storage confusion caused by inappropriate size, greatly improves the convenience of material management in the production process, and comprehensively enhances the practicality and versatility of the cache device. After the adjustment is completed, tighten the fasteners again to ensure that the adjustment wall is stable. This adjustable design greatly improves the adaptability of the structure, can calmly cope with the storage needs of various specifications of ring bodies, and significantly enhances the practicality and versatility of the cache device.

[0014] As a further configuration of the present invention, the transfer mechanism includes a transfer frame, a transfer seat, an approach motor and a clamp. The transfer frame is provided with a slide rail along the width direction of the placement slot, the slide rail is arranged above the high part of the placement slot, the transfer seat is slidably cooperated with the transfer frame, the approach motor is arranged on the transfer seat, the output end of the approach motor is arranged along the height direction of the base, and the clamp is arranged on the output end of the approach motor.

[0015] The beneficial effect of this arrangement is that the slide rails arranged along the width direction of the placement slot on the transfer rack are precisely erected above the high part of the placement slot, providing a stable path for the movement of the transfer seat. The transfer seat and the transfer rack slide together, and can flexibly move laterally along the slide rail under the drive of the approach motor. The output end of the approach motor is vertically arranged and connected to the clamp. This design enables the clamp to accurately align the material. In conjunction with the corresponding placement slot, when the material needs to be placed, the transfer seat only needs to move along the width direction of the placement slot to quickly reach the material position. The approach motor drives the clamp downward, and after accurately grabbing the material, it moves laterally again to transport the material to the top of the placement slot. The clamp is then released, and the material falls into the placement slot. Compared with the traditional method that requires movement along the length direction, this design does not require a complex long-distance movement path, simplifies the structure, reduces energy loss and time cost during the transfer process, and truly realizes efficient, fast and easy-to-use material placement operations, significantly optimizing the operating efficiency of the entire bearing inner and outer ring isothermal cache device.

[0016] As a further configuration of the present invention, the notch of the discharge chute is arranged side by side with the placement chute, and the discharge chute is located below the movement track of the transfer seat.

[0017] The beneficial effect of this arrangement is that it optimizes the material placement process. When the material is output through the discharge chute, the transfer seat can immediately align the material by moving along the predetermined trajectory. Without additional steering or adjustment actions, the gripper can be directly driven to grab the material, and then quickly transferred to the top of the placement chute for placement, which greatly saves material transfer time and greatly improves the convenience and efficiency of material placement.

[0018] As a further configuration of the present invention, an identification probe is provided in the discharge port, and the identification probe is communicatively connected with the transfer mechanism.

[0019] The beneficial effect of this setting is that when the material arrives at the discharge port, the identification probe can quickly capture its trace and immediately feed back the signal to the transfer mechanism connected to it. Based on this, the transfer mechanism does not need to wait blindly, but starts immediately when it receives the signal, accurately drives the transfer seat to move along the predetermined trajectory to the material position, and the gripper grabs the material and transfers it to the placement slot. This efficient linkage mechanism greatly shortens the time for materials to wait for transfer and significantly improves the overall operation efficiency.

[0020] As a further configuration of the present invention, a material collecting channel is also provided on the storage rack, and the material collecting channel is provided near the lower part of the placement slot.

[0021] The beneficial effect of such arrangement is that such arrangement facilitates the collection of materials and improves the utilization efficiency of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

This process not only realizes the initial transfer of materials, but also ensures the stability of the transportation process, and avoids damage to the inner and outer rings due to shaking. Next, the push motor 7 performs a push operation corresponding to the position of the horizontal material channel 22, pushing the material to the feed trough 231 of the lifting channel 23. The feed trough 231, the material trough 232 and the discharge trough 233 are interconnected, and the connection end of the material trough 232 and the discharge trough 233 is shorter than the connection end of the material trough 232 and the feed trough 231. This inclined design allows the material to slide smoothly from the feed trough 231 to the discharge trough 233 under the assistance of gravity.

The transfer mechanism responds quickly at this time, grabs the ring body and sends it into the placement slot 11 of the storage rack 1, realizing efficient caching of the material. This caching method not only ensures the stability of materials during the caching process and reduces the risk of collision, but also greatly improves the efficiency of material transfer and caching through the coordinated operation of various mechanisms, providing a stable and orderly material supply for subsequent production processes, and effectively improving the operating efficiency of the entire production system.

At the same time, the size of the feed trough 231 is adapted to the size of the rectangular projection of the bearing ring body on the vertical plane. This ensures that the ring body can be accurately positioned in a vertical state during the process of sliding down the guide slope into the feed trough 231.
