Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of rotating shaft production equipment, and particularly relates to a motor rotating shaft turnover frame. Background Technology
[0002] The machine shaft is a major component of the motor. After processing, the machine shaft needs to be placed in a turnover rack for easy storage and transportation.
[0003] Generally, the pivot frame is welded from structural steel and steel plate, with the pivot in direct contact with the base plate and each layer of pivots, making it extremely prone to collisions. Alternatively, wooden strips can be embedded inside the frame, with blocks installed on the strips to isolate the pivots. However, the wooden strips are easily damaged, and the pivot surface is prone to accumulating sawdust. Furthermore, the blocks may fall off over time, and failure to replace them promptly can easily lead to collisions with the pivots. Utility Model Content
[0004] This utility model addresses the problems in the prior art by proposing the following technical solution: A motor shaft turnover frame includes a crossbeam, a rigid plastic bracket fixedly connected to the top of the crossbeam, and a column fixedly connected to the side wall. A tray is fixedly installed on the top of the column, and an anti-deviation column is telescopically installed in the bottom storage groove. A connecting shaft is rotatably installed in the top groove of the column. A gear and a cam are fixedly sleeved on the outer ring of the connecting shaft. The tray has a positioning hole that communicates with the top groove of the column. The anti-deviation column passes through the positioning hole and abuts against two cams.
[0005] As a preferred embodiment of the above technical solution, the two connecting shafts, gears and cams are all mirror images of each other, and the outer periphery of the cam is fixedly fitted with an anti-slip pad.
[0006] As a preferred embodiment of the above technical solution, a guide groove is provided on the side wall of the storage groove at the bottom of the column, a guide block is fixedly connected to the side wall of the anti-deviation column, the guide block is slidably connected to the guide groove, and a spring is fixedly connected to one end of the anti-deviation column, the spring being fixedly connected to the side wall of the storage groove.
[0007] As a preferred embodiment of the above technical solution, the tray has a through hole that communicates with the groove at the top of the column. A lower pressure plate is movably fitted inside the through hole. A rack and a second spring are fixedly connected to one side of the lower pressure plate. The rack meshes with a gear for transmission. One end of the second spring is fixedly connected to the side wall of the through hole.
[0008] The beneficial effects of this utility model are as follows: 1. The rigid plastic bracket at the top of the crossbeam of this utility model replaces the traditional steel / steel plate. Its material has moderate hardness and smooth surface, which can not only stably support the rotating shaft, but also avoid scratches and bumps caused by direct friction with the surface of the rotating shaft, thus protecting the processing accuracy and appearance quality of the rotating shaft. Moreover, the rigid plastic material does not produce wood chips, which solves the pollution problem of "wood chips sticking to the rotating shaft" in the traditional wooden strip turnover frame from the root, eliminating the need for additional cleaning procedures and reducing subsequent processing costs. Meanwhile, the anti-deviation column and the tray work together to limit the rotation shaft laterally and vertically, preventing the shaft from colliding due to shaking or sliding during turnover, thus further improving the protection effect.

[0011] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0012] Example like Figure 1 and Figure 2As shown, the motor shaft turnover frame includes a crossbeam 11. A rigid plastic bracket 12 is fixedly connected to the top of the crossbeam 11, and a column 13 is fixedly connected to the side wall. The crossbeam 11 serves as the basic load-bearing structure of the turnover frame, stably connecting and supporting the rigid plastic bracket 12 at the top and the column 13 on the side wall, ensuring the structural strength of the entire turnover frame and preventing frame deformation when placing or transporting the shaft workpiece. This provides a stable reference for the subsequent installation and functional realization of various components. The rigid plastic bracket 12, on the one hand, has material properties that prevent scratching the surface of the workpiece when in direct contact with it, protecting the precision and appearance of the shaft; on the other hand, the bracket structure can support the shaft workpiece, allowing it to be placed orderly on the bracket and preventing it from sliding or colliding during turnover. The column 13 plays a dual role of "intermediate connection and support," both by being fixed to the crossbeam 11 through the side wall to provide stable support for the top tray 14, and by being folded down at the bottom. The storage groove provides installation and telescopic space for the anti-deviation column 20, while the top groove provides a rotating mounting position for the connecting shaft 30, gear 31, and cam 32. It is the core component integrating the upper and lower structures of the turnover frame. The top of the column 13 is fixedly installed with a tray 14, which is mainly used for auxiliary positioning and load bearing. It can cooperate with the rigid plastic bracket 12 to form a "double-layer" or "multi-directional" workpiece limiting structure, further limiting the movement range of the rotating shaft workpiece. The positioning hole opened therein can accurately guide the anti-deviation column 20 through, ensuring that the anti-deviation column 20 and the cam 32 are in stable contact, avoiding transmission failure caused by the deviation of the anti-deviation column 20. The bottom storage groove is telescopically installed with the anti-deviation column 20. The top groove of the column 13 is rotatably installed with the connecting shaft 30. The outer ring of the connecting shaft 30 is fixedly sleeved with the gear 31 and the cam 32. The tray 14 has a positioning hole that communicates with the top groove of the column 13. The anti-deviation column 20 passes through the positioning hole and abuts against the two cams 32.
[0013] Specifically, the anti-deviation column 20 cooperates with the cam 32 so that when the cam 32 rotates with the connecting shaft 30, its eccentric structure can push the anti-deviation column 20 to extend and retract along the positioning hole. When the anti-deviation column 20 extends, it can play a "lateral limiting" role on the adjacent turnover frame or the workpiece in the frame, preventing misalignment or tipping when the turnover frames are stacked, or lateral displacement of the workpiece during handling. When the anti-deviation column 20 retracts, it can reduce the space occupied by the turnover frame, making it convenient for storage or stacking. The connecting shaft 30 and the gear 31 provide a fixed and rotating carrier for the gear 31 and the cam 32, ensuring that the two rotate synchronously. The gear 31, as a power transmission medium, can receive external driving force, such as the power of the rack 34 driven by the subsequent lower pressure plate 33, and convert the power into the rotation of the connecting shaft 30, thereby driving the cam 32 to move, realizing the core logic of "power transmission - component linkage".
[0014] like Figure 2As shown, the two connecting shafts 30, gear 31 and cam 32 are all mirror images, and the outer periphery of cam 32 is fixedly fitted with an anti-slip pad.
[0015] Specifically, the two connecting shafts 30, gear 31 and cam 32 are symmetrically distributed, which can ensure that the two cams 32 apply force to the anti-deviation column 20 synchronously. This avoids uneven force on the anti-deviation column 20 and tilting and jamming caused by the cam 32 on one side applying force, and ensures that the anti-deviation column 20 can extend and retract smoothly along the positioning hole, thereby improving the stability of transmission and limit. At the same time, the symmetrical structure can also make the force on both sides of the turnover frame more balanced and extend the overall service life. The anti-slip pad around the cam 32 can increase the friction between the cam 32 and the anti-deviation column 20, preventing slippage during the contact transmission process. Without the anti-slip pad, the cam 32 may slide relative to the anti-deviation column 20 due to its smooth surface, resulting in insufficient or delayed extension stroke of the anti-deviation column 20, which cannot achieve the limit in time. The anti-slip pad can ensure that the rotational power of the cam 32 is accurately transmitted to the anti-deviation column 20, ensuring the reliability of the limit function.
[0016] like Figure 2 As shown, a guide groove 131 is provided on the side wall of the storage groove at the bottom of the column 13. A guide block 21 is fixedly connected to the side wall of the anti-deviation column 20. The guide block 21 is slidably connected to the guide groove 131. A spring 22 is fixedly connected to one end of the anti-deviation column 20. The spring 22 is fixedly connected to the side wall of the storage groove.
[0017] It should be noted that the guide block 21 can slide directionally along the guide groove 131, which plays a strict constraint role on the extension and retraction trajectory of the anti-deviation column 20—preventing the anti-deviation column 20 from radial displacement, torsion and other problems during the extension and retraction process, avoiding the anti-deviation column 20 from getting stuck in the positioning hole or storage groove, ensuring that it always moves stably along a straight line, and ensuring the smooth realization of the limit function. When spring 22 is in its natural state, it can pull the anti-deviation column 20 back into the storage slot at the bottom of the column 13, realizing the "automatic reset" of the anti-deviation column 20. When the cam 32 rotates to the non-pushing position, the pulling force of spring 22 can quickly retract the anti-deviation column 20 without manual operation, which not only improves the convenience of use, but also avoids collision damage caused by the anti-deviation column 20 being extended for a long time. At the same time, the preload of spring 22 can also keep the anti-deviation column 20 in contact with the cam 32, ensuring that the anti-deviation column 20 can be pushed out immediately when the cam 32 rotates, without transmission gap.
[0018] like Figure 2 As shown, the tray 14 has a through hole 141 that communicates with the groove at the top of the column 13. The inner ring of the through hole 141 is movably fitted with a lower pressure plate 33. A rack 34 and a second spring 35 are fixedly connected to one side of the lower pressure plate 33. The rack 34 meshes with the gear 31 for transmission. One end of the second spring 35 is fixedly connected to the side wall of the through hole 141.
[0019] It should be noted that the through hole 141 provides movable installation space for the lower pressure plate 33 and restricts the lower pressure plate 33 to move only along the axial direction of the through hole 141, so as to prevent the lower pressure plate 33 from shifting and causing the rack 34 and gear 31 to disengage. As a "manual operation component", the lower pressure plate 33 allows the user to transmit power by pressing the lower pressure plate 33 without the need for additional tools, which simplifies the control method of the extension and retraction of the anti-deviation column 20 and improves the ease of operation. When the lower pressure plate 33 is pressed, the lower pressure plate 33 drives the rack 34 to move along the through hole 141. The rack 34 drives the gear 31 to rotate through meshing transmission, which in turn drives the connecting shaft 30 and the cam 32 to rotate synchronously. This realizes the conversion from "manual pressing action" to "cam 32 rotation power", providing controllable driving force for the extension and retraction of the anti-deviation column 20, allowing users to actively control the extension limit of the anti-deviation column 20 according to their needs (such as when stacking turnover frames). In its natural state, spring 35 can push the lower pressure plate 33 back to its initial position, thereby driving the rack 34 to move back, so that the gear 31, connecting shaft 30 and cam 32 return to their initial state. After pressing the lower pressure plate 33, releasing the hand will automatically complete the component reset by the elastic force of spring 35, without the need to manually pull back the lower pressure plate 33, further improving the convenience of operation. At the same time, the preload of spring 35 can also ensure that the rack 34 and gear 31 are always tightly meshed, avoiding power transmission delay or failure caused by meshing gap.
[0020] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
