Description

Technical Field

[0001] This utility model relates to the field of workpiece stacking and feeding technology, and in particular to a stacking device for annular workpieces. Background Technology

[0002] Many ring-shaped workpieces are used in machining, such as bearing end caps, bearing rings and other bearing components. When these workpieces are stacked, corresponding columns are usually set up for positioning to reduce the possibility of them collapsing.

[0003] Existing ring workpiece stacking devices generally include a base and a positioning column set on the base. The outer diameter of the positioning column is adapted to the ring workpieces to be stacked. Therefore, when the size of the positioning column is fixed, the size of the corresponding ring workpiece is also fixed, which is not versatile. Utility Model Content

[0004] To address the problem that existing ring-shaped workpiece stacking devices generally include a base and a positioning column set on the base, with the outer diameter of the positioning column adapted to the ring-shaped workpieces to be stacked, thus the size of the ring-shaped workpiece is fixed when the size of the positioning column is fixed, resulting in insufficient versatility, this application provides a ring-shaped workpiece stacking device, the specific solution of which is as follows.

[0005] A stacking device for annular workpieces includes a frame with multiple lifting plates on the frame. Each lifting plate has a hollow center. The frame has multiple positioning rods at positions corresponding to the hollow centers of the lifting plates. The lifting plates are slidably connected to the positioning rods. The positioning rods are equidistantly spaced along the circumferential center of the lifting plates. Each lifting plate has a sliding groove corresponding to a positioning rod. The sliding groove extends from the hollow center of the lifting plate toward the positioning rod, allowing the positioning rod to slide along the sliding groove.

[0006] By adopting the above technical solutions, the sliding connection design between the lifting plate and the positioning rod allows for convenient placement and removal of ring-shaped workpieces. Simultaneously, the positioning rods are evenly spaced along the circumference of the lifting plate's center, ensuring the stability of the workpieces during stacking and avoiding the risk of collapse due to uneven stress. The sliding groove allows the sliding rods to be adjusted according to the size of the workpiece, enabling the placement of workpieces of various sizes and further improving versatility.

[0007] Optionally, a sliding guide rail is provided on the frame corresponding to the positioning rod, and a sliding block is fixedly provided at the bottom of the positioning rod. The sliding block is slidably connected to the sliding guide rail and moves along the sliding guide rail.

[0008] By adopting the above technical solution, a sliding guide rail is installed on the frame, and a sliding block is fixed at the bottom of the positioning rod, so that the sliding block is slidably connected to the sliding guide rail, thereby realizing the stable movement of the positioning rod. This solution can effectively improve the movement accuracy of the positioning rod, ensure its smooth sliding within the lifting plate, and enhance the stability of the entire stacking device, avoiding the problem of unstable stacking of ring-shaped workpieces due to the shaking of the positioning rod.

[0009] Optionally, an adjustment disc is provided between each of the positioning rods, and the outer side of the adjustment disc is detachably connected to the positioning rod.

[0010] By adopting the above technical solutions, the adjusting plate connects all the positioning rods, enhancing the stability of the overall structure and preventing the positioning rods from shifting or shaking during lifting. The detachable connection between the adjusting plate and the positioning rods facilitates adjusting the position of the positioning rods or replacing the adjusting plate according to actual needs, improving the adaptability and maintenance convenience of the device.

[0011] Optionally, the adjustment discs are respectively disposed at the upper and lower ends of the positioning rod.

[0012] By adopting the above technical solution, the adjusting discs are located at the upper and lower ends of the positioning rod, which effectively enhances the overall stability of the positioning rod and prevents tilting or swaying during stacking. At the same time, the design of the adjusting discs at the upper and lower ends helps to optimize the force distribution, reduce the risk of deformation caused by uneven force on individual positioning rods, and thus improve the load-bearing capacity and reliability of the entire stacking device.

[0013] Optionally, the positioning rods are provided in three pieces and are equidistantly spaced along the adjustment plate. The adjustment plate has an embedding groove corresponding to the positioning rod, and the positioning rod can be embedded in the embedding groove.

[0014] By adopting the above technical solution, three positioning rods are set and evenly distributed along the adjusting plate, which makes the force on the ring-shaped workpieces more uniform when stacked, avoiding the problem of workpiece deformation or slippage caused by uneven force. At the same time, the embedding groove on the adjusting plate can firmly embed the positioning rods, enhancing the stability of the structure and further improving the reliability of stacking ring-shaped workpieces.

[0015] Optionally, a gripping hole is provided in the middle of the adjustment disk, and the gripping hole extends through the adjustment disk.

[0016] By adopting the above technical solution, a gripping hole is opened in the middle of the adjustment plate and extends through the adjustment plate, making it convenient for operators to grasp and rotate the adjustment plate by hand through the gripping hole, thereby facilitating the adjustment of the position of the positioning rod and improving the ease of operation.

[0017] Optionally, the lifting plate includes a ring and a plate, with a mounting groove on the ring corresponding to the plate, and the plate is detachably connected to the mounting groove.

[0018] By adopting the above technical solution, the lifting platform consists of a ring and a disc, with the disc detachably connected to the mounting groove of the ring. This structural design makes the assembly of the lifting platform more flexible, facilitates disassembly and maintenance according to actual needs, improves the efficiency of parts replacement, and reduces maintenance costs.

[0019] Optionally, the frame has multiple drive holes corresponding to the lifting plate, and the drive holes are for the rods that push the lifting plate to extend into.

[0020] By adopting the above technical solution, driving holes are set on the frame, so that the rod that pushes the lifting plate can be accurately inserted, thereby providing a stable driving force for the lifting plate and ensuring a smooth and reliable lifting process.

[0021] In summary, this application has at least the following beneficial effects:

[0022] This application solves the problem of insufficient versatility in existing ring workpiece stacking devices, which generally include a base and a positioning column set on the base. The outer diameter of the positioning column is adapted to the ring workpieces to be stacked. Therefore, when the size of the positioning column is fixed, the size of the corresponding ring workpiece is also fixed. This application solves the problem by setting an adjustable positioning column, which can adjust the size of the positioning column by changing the size of the adjustment plate, and can be adjusted according to the size of the workpiece.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] A stacking device for ring-shaped workpieces, such as Figure 1 and Figure 2As shown, the system includes a frame 1 with multiple lifting plates 2. Each lifting plate 2 is hollow in the center. Multiple positioning rods 3 are positioned on the frame 1 corresponding to the hollow portions of the lifting plates 2. The lifting plates 2 are slidably connected to the positioning rods 3. The positioning rods 3 are equidistantly spaced along the circumference of the center of the lifting plates 2. A sliding groove 21 is formed on each lifting plate 2 corresponding to the positioning rod 3, extending from the hollow portion of the lifting plate 2 towards the positioning rod 3. The positioning rod 3 can slide along the sliding groove 21. In practice, the lifting plates 2 can be lifted by external driving components such as cylinders or hydraulic cylinders, facilitating the removal of workpieces. The positioning rods 3 can be adjusted along the sliding groove 21 according to the size of the workpiece, allowing workpieces of different sizes to be fed in and stored. The frame 1 shown in the figure has four sets of lifting plates 2 and positioning rods 3, but different component configurations are depicted.

[0031] like Figure 1 and Figure 2 As shown, a sliding guide rail 11 is provided on the frame 1 corresponding to the positioning rod 3, and a sliding block 31 is fixedly provided at the bottom of the positioning rod 3. The sliding block 31 is slidably connected to the sliding guide rail 11 and moves along the sliding guide rail 11. In specific implementation, the sliding block 31 and the sliding guide rail 11 provide guidance for the sliding of the positioning rod 3, further improving the stability of the positioning rod 3 during adjustment.

[0032] like Figure 1 and Figure 2 As shown, an adjusting plate 32 is provided between each positioning rod 3, and the outer side of the adjusting plate 32 is detachably connected to the positioning rod 3. The adjusting plate 32 is respectively provided at the upper and lower ends of the positioning rod 3. There are three positioning rods 3, which are equally spaced along the adjusting plate 32. The adjusting plate 32 has an embedding groove 321 corresponding to the positioning rod 3, and the positioning rod 3 can be embedded in the embedding groove 321. A gripping hole 322 is provided in the middle of the adjusting plate 32, and the gripping hole 322 is provided through the adjusting plate 32. In specific implementation, the adjusting plate 32 is generally circular in shape. The adjusting plate 32 is the main support for adjusting the position of the positioning rod 3, and it can make the positioning rod 3 more stable in the set position. When it needs to be removed, it can be removed through the gripping hole 322. When removing the bottom adjusting plate 32, the lifting plate 2 needs to be removed and replaced. The adjusting plate 32 and the positioning rod 3 can be fixed by bolts or by using a protrusion for abutment.

[0033] like Figure 1 and Figure 2 As shown, the lifting plate 2 includes a ring 22 and a plate 23. The ring 22 has a mounting groove corresponding to the plate 23, and the plate 23 can be detachably connected to the mounting groove. In practice, when replacing the bottom adjusting plate 32, only the plate 23 needs to be removed, which further improves the convenience of replacement.

[0034] like Figure 1 and Figure 2 As shown, the frame 1 has multiple drive holes 12 corresponding to the lifting plate 2, and the drive holes 12 allow the rods that push the lifting plate 2 to extend into them. In specific implementation, the piston rods of the air cylinder and the hydraulic cylinder can pass through the drive holes 12 and push the lifting plate 2 to move vertically.

[0035] Working principle: By changing the adjustment plate 32, the positions of the three positioning rods 3 can be changed, thereby adjusting the size of the workpiece that can be placed and further improving the versatility of storing workpieces.

[0036] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
