[0002] In the subsequent steps of the round bar production process, a full-circumference inspection of the outer surface of the round bar is required to ensure the production qualification rate of the round bar.

[0003] Currently, when performing peripheral inspection on a round bar, the bar needs to be placed on a flat surface and then manually pushed to make it roll, thus completing the full-circle appearance inspection.

[0004] However, manual operation not only increases the labor intensity of staff, but may also lead to missed detections due to uneven rotation speed or angular deviation, affecting detection efficiency and accuracy. Summary of the Invention

[0005] The purpose of this application is to provide an automatic rotating device for external inspection of round bars, so as to solve the technical problems in the prior art where manual operation not only increases the labor intensity of workers, but may also lead to missed inspections due to uneven rotation speed or angular deviation, thus affecting the inspection efficiency and accuracy.

[0006] To achieve the above objectives, the technical solution adopted in this application is: to provide an automatic rotating device for external inspection of round bars, comprising: Base; Two sets of support components are arranged opposite each other on the base and are used to support both ends of the round bar so that the round bar is in a horizontal state; A pad, located between the two sets of support members, the pad having a friction surface facing the round bar; and A movable component is disposed on the base and connected to the pad. When the movable component drives the pad to pass through the bottom of the round bar, it pushes the round bar upward and drives the round bar to rotate by means of the friction surface.

[0007] In one possible implementation, based on the above technical solutions, the supporting component includes: A support base is provided on the base; A lifting seat, vertically slidable on the support base, has an arc-shaped groove at its top for placing the round bar; and A support spring is vertically installed inside the support base, and the top of the support spring is connected to the bottom of the lifting base; When the round bar is placed on the lifting seat, the support spring is in a compressed state.

[0008] In one possible implementation, based on the above technical solutions, the support base is laterally slidably connected to the base, and the sliding direction of the support base is perpendicular to the moving direction of the pad; the automatic rotating device for external inspection of round bars further includes: An adjustment component, disposed on the base, is used to move the two support seats closer together or further apart; Two sets of lifting components correspond one-to-one with the two sets of support components and are connected to the bottom of the support spring; and A linkage component is connected between the adjustment component and the two sets of lifting components; When the two support seats are far apart, the linkage component drives the two sets of lifting components to move simultaneously, and the lifting components drive the bottom of the corresponding support spring to compress upward.

[0009] In one possible implementation, based on the above technical solutions, the adjustment component includes: An adjusting screw is rotatably mounted on the base. The adjusting screw has two threads with opposite directions of rotation, and the two support seats are respectively threaded onto the two threads with opposite directions of rotation; and An adjustment motor is mounted on the base and is connected to the adjustment screw via a transmission mechanism.

[0010] In one possible implementation, based on the above technical solutions, the lifting component includes: A chassis is disposed within the support base, and the upper surface of the chassis is connected to the bottom of the support spring; A lifting screw is vertically slidably disposed within the support base, and the top of the lifting screw is fixed to the chassis; and A screw sleeve is rotatably disposed within the support base and threadedly connected to the lifting screw. When the two support seats move away from each other, and the linkage component drives the screw sleeve to rotate, the lifting screw drives the chassis to move upward.

[0011] In one possible implementation, based on the above technical solutions, the linkage component includes: Two linked gears, each corresponding to one of the two threaded sleeves, are coaxially fixed to the threaded sleeves; and A linkage rack is fixed on the base and parallel to the adjusting screw; the linkage rack meshes with two linkage gears simultaneously, and the linkage rack passes through two support seats.

[0012] In conjunction with the above technical solutions, in one possible implementation, the automatic rotating device for external inspection of round bars further includes: A movable block, connected to the movable component, the movable component being used to move the movable block, and a pad block slidably disposed vertically on the movable block; and A height adjustment component is provided on the movable block for adjusting the height of the pad block.

[0013] In one possible implementation, based on the above technical solutions, the height adjustment component includes: A height adjustment screw is vertically threaded onto the movable block, and the top end of the height adjustment screw is rotatably connected to the pad block; and Several guide rods are vertically fixed to the bottom of the pad, and the bottom of the guide rods is vertically slidably disposed within the movable block.

[0015] In one possible implementation, based on the above technical solutions, multiple rotating shafts are rotatably arranged within the arc-shaped groove at the top of the lifting seat, and the axial direction of the rotating shafts is parallel to the sliding direction of the support seat.

[0016] The beneficial effects of the automatic rotation device for external inspection of round bars provided in this application are as follows: Compared with the prior art, this application can effectively support both ends of the round bar through two sets of opposing support components, so that the round bar is always kept in a horizontal position. The moving component can drive the pad to move smoothly and controllably toward the round bar. The friction surface of the pad is designed as an inclined surface or a circular arc surface, which can improve the effectiveness of friction transmission between the two. The pad pushes the round bar to rotate through the friction force with the surface of the round bar, so that the round bar can maintain a continuous and uniform rotation state during the external inspection process, which facilitates the inspector to perform full-circumference appearance inspection of the outer surface of the round bar.

[0017] It replaces the traditional manual operation of pushing the round bar, which can effectively reduce the labor intensity of the staff. At the same time, it makes the rotation speed and rotation angle of the round bar more controllable, allowing the inspectors to inspect the outer surface of the round bar more clearly and comprehensively, improving the overall efficiency of the external inspection of the round bar, and making the external inspection process smoother, reducing the situation of incomplete inspection and observation caused by poor rotation.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0024] In the description of this application, "multiple" means two or more, and "several" means one or more, unless otherwise expressly and specifically defined.

[0025] The present application provides an automatic rotating device for external inspection of round bars.

[0026] like Figure 1 and Figure 2 As shown, one embodiment of this application provides an automatic rotating device for external inspection of round bars, including a base 1, a support member 2, a pad 3, and a moving assembly 4. The support member 2 has two sets, arranged opposite each other on the base 1, and is used to support both ends of the round bar so that the round bar is in a horizontal state.

[0027] The pad 3 is located between the two sets of support components 2. The pad 3 has a friction surface facing the round bar. The friction surface can be an inclined surface or an arc surface. The moving component 4 is set on the base 1 and connected to the pad 3. When the moving component 4 drives the pad 3 to pass through the bottom of the round bar, it pushes the round bar upward and drives the round bar to rotate with the help of the friction surface.

[0028] This embodiment provides an automatic rotation device for external inspection of round bars. Compared with the prior art, it effectively supports both ends of the round bar through two sets of opposing support components 2, ensuring that the round bar remains horizontal at all times. The moving component 4 can drive the pad 3 to move smoothly and controllably toward the round bar. The friction surface of the pad 3 is designed as an inclined surface or an arc surface, which can improve the effectiveness of friction transmission between the two. The pad 3 pushes the round bar to rotate through the friction force with the surface of the round bar, allowing the round bar to maintain a continuous and uniform rotation state during external inspection, which facilitates the inspector to perform full-circumference appearance inspection of the outer surface of the round bar.

[0029] It replaces the traditional manual operation of pushing the round bar, which can effectively reduce the labor intensity of the staff. At the same time, it makes the rotation speed and rotation angle of the round bar more controllable, allowing the inspectors to inspect the outer surface of the round bar more clearly and comprehensively, improving the overall efficiency of the external inspection of the round bar, and making the external inspection process smoother, reducing the situation of incomplete inspection and observation caused by poor rotation.

[0030] like Figures 3-4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The support component 2 includes a support base 21, a lifting seat 22, and a support spring 23. The support base 21 is mounted on the base 1; the lifting seat 22 is vertically slidably mounted on the support base 21, and the top of the lifting seat 22 has an arc-shaped groove for placing a round bar.

[0031] The support spring 23 is vertically installed inside the support base 21, and the top of the support spring 23 is connected to the bottom of the lifting base 22; wherein, when the round bar is placed on the lifting base 22, the support spring 23 is in a compressed state.

[0032] When a round bar of a specific weight is placed on the lifting seat 22, the weight of the round bar itself will exert downward pressure on the lifting seat 22, causing the support spring 23 to compress and deform. At this time, the bottom edge of the round bar can be precisely aligned with the bottom of the pushing friction surface of the pad 3, so as to make precise position matching for the subsequent action of the pad 3 to rub and push the round bar, and allow the pushing action of the pad 3 to act on the round bar more efficiently.

[0033] During the process of the pad 3 rubbing and pushing the round bar, causing it to rotate, the round bar will move upwards. At this time, the support spring 23, which is in a compressed state, will use its elastic restoring force to drive the lifting seat 22 to move upwards synchronously along the support seat 21, thus providing continuous and effective support for the round bar and keeping it in a stable horizontal state during rotation. At the same time, the synchronous upward movement of the lifting seat 22 driven by the support spring 23 ensures that the pad 3 and the round bar maintain good frictional contact, reducing the workload of the moving component 4 and ensuring the continuous rotation of the round bar.

[0034] like Figures 2-3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The support base 21 is slidably connected to the base 1, and the sliding direction of the support base 21 is perpendicular to the moving direction of the pad block 3; the automatic rotation device for external inspection of round bars also includes an adjustment component 5, two sets of lifting components 6 and a linkage component 7.

[0035] Adjustment component 5 is mounted on base 1 and is used to move the two support seats 21 closer to each other or further apart; two sets of lifting components 6 correspond one-to-one with two sets of support components 2 and are connected to the bottom of support spring 23; linkage component 7 is connected between adjustment component 5 and two sets of lifting components 6.

[0036] When the two support seats 21 move away from each other, the linkage component 7 drives the two sets of lifting components 6 to move simultaneously, and the lifting components 6 drive the bottom of the corresponding support spring 23 to compress upward.

[0037] The adjustment component 5 can move the two support seats 21 closer or further apart, thereby adjusting the distance between the two sets of support components 2, so as to adapt to the support requirements of the two ends of round bars with the same diameter but different lengths.

[0038] When the diameter of the tested round bar remains constant but its length increases, its own weight will also increase accordingly. At this time, the adjustment component 5 drives the two support seats 21 to move away from each other, and the linkage component 7 will drive the two sets of lifting components 6 to move together. The lifting component 6 can drive the bottom of the corresponding support spring 23 to move upward and achieve further compression, thereby increasing the elastic deformation of the support spring 23 and thus improving the elastic support force of the support spring 23, which can better support the round bar with a larger weight.

[0039] Meanwhile, the further compression of the support spring 23 can counteract the downward displacement of the lifting seat 22 caused by the increased weight of the round bar, effectively maintaining the overall height stability of the round bar after placement, ensuring that the bottom edge of the round bar can always maintain a precise positional match with the friction surface of the pad block 3, and guaranteeing the smooth operation of the round bar's rotation.

[0040] like Figures 2-3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The adjustment assembly 5 includes an adjustment screw 51 and an adjustment motor 52. The adjustment screw 51 is rotatably mounted on the base 1. The adjustment screw 51 is divided into two sections with opposite directions of rotation in its middle section. Two support seats 21 are threadedly connected to the threads with different directions of rotation, respectively. The adjustment motor 52 is mounted on the base 1 and is driven by the adjustment screw 51.

[0041] When the adjusting motor 52 drives the adjusting screw 51 to rotate, the two support seats 21 will move synchronously towards or away from each other along the adjusting screw 51 under the action of the thread. The transmission accuracy is high, and the distance between the two support seats 21 can be precisely controlled.

[0042] like Figures 3-4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The lifting assembly 6 includes a chassis 61, a lifting screw 62, and a screw sleeve 63. The chassis 61 is disposed inside the support base 21, and the upper surface of the chassis 61 is connected to the bottom of the support spring 23.

[0043] The lifting screw 62 is vertically slidably disposed within the support base 21, and the top of the lifting screw 62 is fixed to the chassis 61; the screw sleeve 63 is rotatably disposed within the support base 21 and is threadedly connected to the lifting screw 62.

[0044] When the two support seats 21 move away from each other, and the linkage component 7 drives the screw sleeve 63 to rotate, the lifting screw 62 drives the chassis 61 to move upward.

[0045] When the two support seats 21 move away from each other, and the linkage component 7 drives the screw sleeve 63 to rotate within the support seat 21, the screw sleeve 63 and the lifting screw 62, driven by the rotation of the screw sleeve 63, cause the lifting screw 62 to move smoothly upward in the vertical direction, thereby driving the integral chassis 61 to move upward synchronously. The upward movement of the chassis 61 creates a uniform upward thrust on the bottom of the support spring 23, thereby further compressing the support spring 23.

[0046] The lifting action achieved through threaded transmission has high transmission precision, which can accurately control the upward movement distance of the chassis 61, and thus accurately control the compression of the support spring 23. This allows the elastic support force of the support spring 23 to be precisely adjusted according to the weight of the round bar, ensuring effective support for round bars of different weights while avoiding elastic loss of the support spring 23 due to excessive compression.

[0047] like Figures 3-4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The linkage assembly 7 includes a linkage gear 71 and a linkage rack 72. There are two linkage gears 71, each corresponding to one of the two threaded sleeves 63, and the linkage gears 71 and the threaded sleeves 63 are fixed coaxially. The linkage rack 72 is fixed on the base 1 and parallel to the adjusting screw 51. The linkage rack 72 meshes with both linkage gears 71 at the same time, and the linkage rack 72 passes through the two support seats 21.

[0048] On the one hand, the linkage rack 72 penetrates the structure of the support base 21, which can provide effective guidance for the sliding movement of the support base 21 during the lateral sliding of the support base 21 along the base 1, strictly limit the sliding direction of the support base 21, and improve the smoothness and stability of the sliding of the support base 21.

[0049] On the other hand, since the linkage rack 72 remains fixed, when the adjusting component 5 moves the support base 21 on the base 1, the support base 21 will move synchronously with the linkage gear 71. The linkage gear 71 will automatically rotate under the meshing action with the fixed linkage rack 72, thereby driving the screw sleeve 63, which is fixed on the same axis, to rotate automatically. There is no need to set a separate power source for the screw sleeve 63, realizing the automatic linkage between the movement of the support base 21 and the rotation of the screw sleeve 63, which simplifies the overall structural design of the device.

[0050] Meanwhile, the meshing transmission between the linkage gear 71 and the rack is timely and has high synchronization, which can ensure that the movement of the support base 21 and the compression adjustment of the support spring 23 are precisely coordinated, thereby improving the overall operating efficiency of the device.

[0051] Furthermore, to improve the lifting stability of the lifting seat 22 and the sliding force stability of the support seat 21, this embodiment has two support springs 23 in each support seat 21, symmetrically arranged along the axis of the adjusting screw 51; the linkage assembly 7 also has two sets, symmetrically arranged on both sides of the adjusting screw 51, with each set of linkage assembly 7 correspondingly connected to the support spring 23 above it. The two support springs 23 provide stable support for the lifting seat 22, and the two linkage racks 72 provide stable guidance for the support seat 21.

[0052] like Figure 5 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The automatic rotation device for external inspection of round bars also includes a moving block 8 and a height adjustment component 9. The moving block 8 is connected to the moving component 4, which is used to drive the moving block 8 to move. The pad 3 is slidably mounted on the moving block 8 vertically. The height adjustment component 9 is mounted on the moving block 8 and is used to adjust the height of the pad 3.

[0053] The height adjustment component 9 is set on the movable block 8, which can flexibly and accurately adjust the vertical height of the pad 3 on the movable block 8. The staff can make targeted adjustments to the height of the pad 3 according to the actual specifications of the round bar being tested, so that the friction surface of the pad 3 can achieve a more precise positional match with the bottom edge of the round bar, and can form a good coordination effect with the action of the linkage component 7 to adjust the compression force of the support spring 23.

[0054] When the linkage component 7 adjusts the compression of the support spring 23 through the lifting component 6 to maintain the stability of the round bar height, if there is a slight deviation in the height of the round bar, the height of the pad 3 can be finely adjusted by the height adjustment component 9 to compensate for the height deviation, so that the friction surface of the pad 3 can be more accurately aligned with the bottom edge of the round bar, improve the friction fit between the pad 3 and the round bar, and ensure the friction pushing effect of the pad 3 on the round bar.

[0055] Meanwhile, by adjusting the height of the pad 3 by adjusting component 9, the device can not only adapt to round bars of the same diameter but different lengths, but also effectively adapt to round bars of different thicknesses. When inspecting round bars that cannot be adapted to the compression coefficient of the support spring 23, the device can also achieve precise frictional pushing and stable rotation by adjusting the height of the pad 3, which greatly improves the overall adaptability of the device to round bars of different specifications, allowing the device to be used in more round bar inspection scenarios.

[0056] like Figure 5 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The height adjustment component 9 includes a height adjustment screw 91 and several guide rods 92. The height adjustment screw 91 is vertically threaded onto the moving block 8, the top end of the height adjustment screw 91 is rotatably connected to the pad block 3, and a handwheel is provided at the bottom end; the several guide rods 92 are vertically fixed to the bottom of the pad block 3, and the bottom of the guide rods 92 are vertically slidably disposed within the moving block 8.

[0057] Workers can manually rotate the height adjustment screw 91 to raise and lower the pad 3 vertically. This simple and convenient operation eliminates the need for complex tools, reducing the difficulty of operation and making the height adjustment process of the pad 3 more efficient. Simultaneously, the threaded drive provides high transmission precision, allowing for accurate control of the lifting distance of the pad 3 and enabling fine-tuning of its height. This ensures a more precise match between the friction surface of the pad 3 and the bottom edge of the round bar.

[0058] like Figures 1-2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The moving component 4 includes a sprocket and chain assembly 41 and a drive motor 42. The sprocket and chain assembly 41 is mounted on the base 1, the moving block 8 is fixed on the chain, the chain transmission direction is horizontal and perpendicular to the sliding direction of the support base 21; the drive motor 42 is mounted on the base 1 and is connected to the sprocket and chain assembly 41.

[0059] The drive motor 42 is mounted on the base 1 and can provide continuous, stable and controllable power output for the transmission of the sprocket and chain assembly 41, laying the power foundation for the movement of the moving block 8.

[0060] The chain drive direction of the sprocket and chain assembly 41 is set horizontally and perpendicular to the sliding direction of the support base 21. The moving block 8 is fixed on the chain. When the drive motor 42 drives the sprocket and chain assembly 41 to drive, the chain will make a smooth horizontal cycle drive, thereby driving the moving block 8 fixed on it to move smoothly horizontally along the chain drive direction.

[0061] The sprocket and chain transmission method features smooth transmission and strong load-bearing capacity, which can drive the pad 3 to move stably, allowing the pad 3 to move closer to or further away from the round bar accurately and smoothly, ensuring more precise position adjustment between the pad 3 and the round bar.

[0062] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: Multiple rotating shafts 221 are rotatably arranged in the arc-shaped groove at the top of the lifting seat 22, and the axial direction of the rotating shafts 221 is consistent with the sliding direction of the support seat 21.

[0063] When the pad 3 rubs and pushes the round bar to rotate on the arc-shaped groove of the lifting seat 22, the outer surface of the round bar will come into contact with the rotating shaft 221 and drive the rotating shaft 221 to rotate. This converts the sliding friction between the round bar and the lifting seat 22 into rolling friction between the round bar and the rotating shaft 221, allowing the round bar to rotate more smoothly and easily under the friction of the pad 3, thus ensuring the stability of the rotation state of the round bar during the external inspection process.

[0064] At the same time, the reduction of frictional resistance can effectively reduce the frictional loss between the pad 3 and the round bar, reduce the wear on the outer surface of the round bar and the friction surface of the pad 3, and also avoid scratches, wear and other damage to the outer surface of the round bar caused by excessive friction, thus ensuring the appearance quality of the round bar.
