Description

Technical Field

[0001] This utility model relates to a material storage mechanism for a flexible bearing. Background Technology

[0002] In bearing production, assembly line operations directly transport materials from one process to the next, significantly improving production efficiency. However, due to varying processing times in different processes, especially in downstream installation where processing times are longer, material accumulation at the input end can occur. Therefore, temporary material storage mechanisms are needed, or a separate storage mechanism may be required for the entire process itself. In existing technologies, material storage generally follows a first-in, first-out (FIFO) principle, and for convenience, materials are fed from top to bottom, falling from the bottom of the storage column and then pushed out. However, when this method is applied to flexible bearings, it can lead to problems such as bearing ring deformation and damage. Summary of the Invention

[0003] In order to overcome the above-mentioned shortcomings in the prior art, this utility model provides a flexible bearing storage mechanism that is convenient for storing and discharging materials and does not deform.

[0004] This utility model is achieved through the following technical solution: A flexible bearing storage mechanism includes a storage rack with multiple storage columns for bearing races to be fitted onto the rack. The storage columns are arranged in a ring. The lower end of the storage rack is connected to the output end of a storage motor. The mechanism is characterized by: multiple mounting seats on the storage rack; the lower ends of the storage columns are respectively mounted on the mounting seats; a conveying mechanism is provided on the outside of the storage rack; the conveying mechanism includes a lead screw arranged in the same direction as the storage columns; a lead screw motor is fixedly connected to the lower end of the lead screw; a lead screw nut is fitted on the lead screw; a bracket is fixedly connected to the lead screw nut; trays are fitted onto the storage columns; bearing races are fitted onto the storage columns and located above the trays; and the bracket supports the trays below the trays.

[0005] Preferably, the lead screw is mounted on a lead screw frame, and the lead screw frame has a longitudinal slide rail on the side near the lead screw. The lead screw nut is connected to the bracket via a connecting rod. A slider is mounted on the slide rail at one end of the connecting rod near the lead screw frame, and the other end of the connecting rod is connected to the bracket.

[0006] Preferably, the lead screw motor is fixed to the bottom of the lead screw frame, and the bracket is forked into a U-shape on both sides.

[0007] Preferably, sensor brackets are fixed at the upper and lower ends of the lead screw frame, and sensors are installed on the sensor brackets.

[0008] Preferably, the tray is disc-shaped, including a sleeve portion fitted onto the storage rod, a step-connected ring portion to the sleeve portion, the outer diameter of the sleeve portion being larger than the inner diameter of the ring, the inner diameter of the sleeve portion being smaller than the outer diameter of the ring, and the forks on both sides of the bracket avoiding the storage rod and located below the ring portion.

[0009] This application uses an externally installed robotic arm to directly store or discharge materials from the top of the storage column. The materials are transported by a pallet, and the pallet is raised and lowered by a bracket during storage or discharge.

[0010] The beneficial effects of this utility model are as follows: This utility model no longer uses a natural drop method for material discharge, but instead directly stores or discharges material from the top of the storage column, and transports it by lifting and lowering a pallet. During the storage or discharge process, this application avoids deformation and damage, making it suitable for flexible bearing rings. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the utility model. Detailed Implementation

[0012] The utility model will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1 As shown, a flexible bearing storage mechanism includes a storage rack 4 with multiple mounting seats. Storage columns 1 for bearing rings are mounted on the mounting seats in a circular arrangement. The lower end of the storage rack is connected to the output of a storage motor 5, which is connected to the storage rack via a transmission mechanism. When the storage motor operates, the storage rack rotates, moving the corresponding storage column to its working position. During storage, once the current storage column is full, the discharge rack rotates, and the empty storage column at the next position rotates to the working position. During discharge, once the current storage column has removed material, the storage column at the next position containing material rotates to the working position.

[0014] The lower ends of the storage columns 1 are directly mounted on the mounting bases. In this application, material is not discharged from below, but is stored and discharged directly from the top. A conveying mechanism is provided on the outside of the storage rack. The conveying mechanism includes a lead screw 10 arranged in the same direction as the storage column. The lower end of the lead screw is fixedly connected to a lead screw motor 12. A lead screw nut 7 is sleeved on the lead screw, and a bracket 3 is fixedly connected to the lead screw nut. A tray 2 is sleeved on each storage column. A bearing ring is sleeved on the storage column and located above the tray 2. The bracket 3 supports the tray below. During storage, the material is sleeved on the storage column and located above the tray. The tray 2 is supported by the bracket 3 and moves up and down. Each time a piece of material is placed, the bracket descends by the height of one piece of material. Similarly, during retrieval, after retrieving one piece of material, the bracket rises by the height of one piece of material. This ensures that the material at the highest position is in the working position.

[0015] The lead screw 11 is mounted on the lead screw frame 6, and the lead screw motor 1 is fixed to the bottom of the lead screw frame. A longitudinal slide rail 10 is provided on the side of the lead screw frame near the lead screw. The lead screw nut is connected to a bracket via a connecting rod 9. A slider 8 is mounted on the slide rail 10 at one end of the connecting rod near the lead screw frame, and the other end of the connecting rod is connected to the bracket. During the lifting and lowering of the lead screw, the relative sliding between the slider and the slide rail increases its operational stability.

[0016] Sensor brackets 11 are fixed at the upper and lower ends of the lead screw frame. Sensors are installed on the sensor brackets and can detect whether there is material in the storage column and whether it is full. The upper sensor detects whether there is material in the storage column, and the lower sensor detects whether the material is full.

[0017] The tray 2 is disc-shaped and includes a sleeve portion 14 that is fitted onto the storage rod, and a stepped ring portion 15 that connects to the sleeve portion. The outer diameter of the sleeve portion is larger than the inner diameter of the ring, and the inner diameter of the sleeve portion is smaller than the outer diameter of the ring. The two sides of the tray are forked into a U-shape, and the two forks of the tray avoid the storage rod and are located below the ring portion. The tray is used to support materials and is driven to move up and down by the support frame.

[0018] The working process of this application will be further explained below. In actual use, this application also requires the cooperation of a robotic arm. The robotic arm grips materials to store in storage column 1 or removes materials for discharge. During storage, the robotic arm grips the material into the corresponding storage column. The material, i.e., the bearing ring, is placed above the tray 3. Each time a material is added, the lead screw is rotated by the lead screw motor, and the lead screw nut 7 descends by one material height until the current storage column is full. The storage motor rotates, and the next empty storage column rotates to the working position. During discharge, the robotic arm grips the material and removes it from the storage column, causing the tray to rise by one material height. After the current storage column is empty, the next storage column containing material rotates to the working position. Sensors on the lead screw frame can detect whether the next storage column contains material and whether it is full.

[0019] This invention eliminates the natural drop method for material discharge, instead directly storing or discharging material from the top of the storage column, and conveying it via a pallet that moves up and down. This design prevents deformation and damage during storage or discharge, making it suitable for flexible bearing rings.
