Description

Technical Field

[0001] The invention relates to the technical field of turning tooling, in particular to a turning tooling for a large mechanical structure. Background Art

[0002] A flip tool is a device used to handle objects. It can transfer objects from one posture to another, or invert objects for processing. A flip tool is usually composed of a bracket, a fixture, and a control system. The main function of a flip tool is to facilitate the assembly, inspection, assembly, or packaging of objects during the production process. It can flip objects to a position suitable for the next step of processing, improving production efficiency and ease of operation. Common ones include rotary flip tools and tilt flip tools. The rotary flip tool rotates the object 360 degrees through a rotating mechanism, and is suitable for objects that need to be processed on multiple surfaces. The tilt flip tool tilts the object to a suitable angle for processing through a tilting mechanism, and is suitable for objects with specific tilting requirements. Flip tools are widely used in industrial production and logistics fields, which can improve production efficiency, reduce labor intensity, and ensure product quality and safety.

[0003] When the existing flip tool flips the plate-type workpiece, the number of flip plates is two. When working, the plate-type workpiece is first placed on one of the flip plates, and then the two flip plates are rotated in opposite directions to a vertical state at the same time and gradually approach each other. Then, the plate-type workpiece on one of the flip plates is flipped and located on the surface of the other flip plate. After the flipping is completed, the two flip plates are rotated in opposite directions to a horizontal state of 180° at the same time, so that the workpiece is in a horizontal state for processing.

[0004] When the above-mentioned existing flipping operation is working, a heavy workpiece is directly flipped onto the surface of another flip plate when flipping. Since the flip plate surface has no external force support, a certain impact force will be generated when the heavier workpiece is flipped. Therefore, if this continues for a long time, the flip plate surface is prone to fracture, reducing the service life of the equipment.

[0005] In view of this, the present invention solves the above technical problems by proposing a large-scale mechanical structure turning tool. Summary of the invention

[0006] In view of the shortcomings of the above-mentioned background technology, the present invention provides a technical solution for a large-scale mechanical structure flipping tooling, which can support the weight of the workpiece when it is flipped, avoid the flip plate from being broken due to the heavy weight of the workpiece being subjected to stress for a long time without external support, and can extend the service life of the equipment, solving the problems raised in the above-mentioned background technology.

[0007] The present invention provides the following technical solutions: a large-scale mechanical structure flipping tool, comprising a body, a motor is fixedly installed on one side surface of the body; a flip plate, two flip plates are rotatably installed in the middle of the body; a support seat, the support seat is slidably installed on the bottom of the flip plate, one end of the support seat can be flipped, which can reduce the occupied space and make the distance between the two flip plates closer to facilitate the flipping of the workpiece, the flipping angle of the support seat is 90°, and the support seat is used to support the workpiece for placement; a supporting mechanism, the supporting mechanism includes a support frame, two adjacent sliding grooves I are opened on both sides of the flip plate, the support frame slides inside the flip plate through one of the sliding grooves I, and the support mechanism can support the weight of the workpiece when it is flipped, so as to avoid the flip plate being broken due to the excessive weight of the workpiece being subjected to stress for a long time without external support, thereby extending the service life of the equipment.

A retractable plug-in block is fixed to the inner wall of the end opposite to the threaded rod II and the threaded rod I, and the bottom of the plug-in block can be correspondingly inserted into the key-shaped groove to fix the rotation angle of the threaded rod I or the threaded rod II. One end of the adjustment component is rotatably connected to a sliding rod, and the end of the sliding rod is slidably connected to a side surface of the body.

[0010] As a preferred technical solution of the present invention, filling pieces are slidably connected to the inner sides of the lower surface of the plug block through a connecting shaft, the surface of the filling piece is elastically connected to the lower surface of the plug block through a spring III, the top of one side of the filling piece is an arc surface, a spring II is fixed to the bottom of the plug block, the bottom of the spring II is fixedly connected to the bottom of the plug block, and inclined blocks are fixedly connected to the two sides of the plug block. When the lower end of the plug block descends, the connecting shaft contacts the inclined block and expands outwardly on both sides of the plug block to contact the two side walls of the key groove, so as to prevent the threaded rod I from stopping or rotating synchronously with the movement state of the threaded rod I due to the gap between the key groove and the plug block when the rotation stops.

[0011] As a preferred technical solution of the present invention, a clamping mechanism is provided on the upper surface of the flip plate, and the clamping mechanism includes a clamping frame and a lifting rod. The clamping mechanism can quickly clamp the flipped workpiece so that it is stably located on the surface of the flip plate, thereby preventing the workpiece from sliding due to the slope when the other flip plate is gradually laid flat to a horizontal state.

[0013] As a preferred technical solution of the present invention, the surface of the clamping roller is covered with a friction pad, and the clamping roller can only rotate in a single circle.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The support frame is located inside the slide groove I to push the flip plate to flip continuously into a vertical state. At this time, the support frame is tilted and supported on the surface of the flip plate. When the workpiece on one surface of the flip plate is flipped and located on the surface of the other flip plate, the support of the support frame on the surface of the flip plate can buffer the impact force of the workpiece when it flips to the surface of the other flip plate, avoiding the fracture of the bottom of the flip plate and affecting subsequent processing.

[0017] 2. When the sliding rod moves in a direction away from the threaded rod I, and the insert blocks on the inner walls of the threaded rods I and II are located in the annular slots, the threaded rod I can be rotated alone, and the flipping angle of the other flip plate can be adjusted to expand the inclination angle of the other flip plate, so that the workpiece can be prevented from slipping when placed on the other flip plate.

[0018] 3. When the filling piece descends and the end of the connecting shaft contacts the inclined surface of the inclined block, the filling piece moves outward on both sides of the plug block and contacts the inner walls of the key groove without gaps, filling the space of the key groove. This can avoid the unstable rotation of threaded rod I or threaded rod II due to the gap during rotation. Therefore, it is more labor-saving during rotation and can accurately determine the rotation angle of threaded rod I and threaded rod II, which is convenient for the support frame to stably support the surface of the flip plate.

[0019] 4. The clamping roller rolls a single circle on the surface of the workpiece to clamp and fix it when it is flipped to the surface of another flip plate, so as to prevent the workpiece from sliding due to its own gravity when it is flipped to the other flip plate, and facilitate the stable flipping and dumping of the workpiece.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0035] During operation, the support seat 306 can be raised and lowered and slid on the surface of the flip plate 2 according to the height of the plate, and then the plate-shaped workpiece can be placed on the surface of one of the flip plates 2 through the support seat 306, and then the two flip plates 2 are continuously flipped to a vertical state, and finally the workpiece on the surface of one of the flip plates 2 is flipped to the surface of the other flip plate 2 to complete the flipping operation.

[0036] The supporting mechanism also includes a slide seat Ⅰ301, which is slidably installed on the top of the body 1 through a slide groove Ⅱ, and the bottom of the support frame 3 is hinged to the two ends of the slide seat Ⅰ301, and the number of slide seats Ⅰ301 corresponds to the number of flip plates 2; a slide seat Ⅱ302, the top of the slide seat Ⅱ302 is fixedly connected to the two sides of the bottom of the slide seat Ⅰ301; a threaded rod Ⅰ4 and a threaded rod Ⅱ406, one end of the threaded rod Ⅰ4 and the threaded rod Ⅱ406 are both rotatably installed on one side of the body 1, the threaded rod Ⅰ4 and the threaded rod Ⅱ406 are relatively arranged through an adjustment component adjustment component 404, and the surfaces of the threaded rod Ⅰ4 and the threaded rod Ⅱ406 are provided with relative thread grooves, one end of the slide seat Ⅱ302 is fixed with a fixed block, and the fixed block is located inside the threaded rod Ⅰ4 and the threaded rod Ⅱ406 through the threaded groove, and the slide seat Ⅱ302 is threaded. Rod I4 and threaded rod II 406 rotate and slide on the surface of the body 1; one end of the threaded rod II 406 is fixedly connected to a toothed ring 402, and a gear 401 is meshed on the surface of the toothed ring 402, and the gear 401 is fixedly installed on the output shaft of the motor; two annular slots 4042 are provided on the surface of the adjustment component 404, and a key groove 4041 adjacent to the annular slot 4042 is provided on the surface of the adjustment component 404, and a bottom retractable plug block 405 is fixed to the inner wall of the end opposite to the threaded rod II 406 and the threaded rod I4, and the bottom of the plug block 405 can be correspondingly inserted into the key groove 4041 to fix the rotation angle of the threaded rod I4 or the threaded rod II 406, and one end of the adjustment component 404 is rotatably connected to a sliding rod 403, and the end of the sliding rod 403 is slidably connected to a side surface of the body 1.

[0037] The support frame 3 slides inside the flip plate 2 through one of the slide grooves Ⅰ201, and then pushes the adjustment component 404 to move in the direction close to the gear ring 402 inside the threaded rod Ⅰ4 and the threaded rod Ⅱ406 through the sliding rod 403, so that the plug block 405 on the inner wall of the threaded rod Ⅰ4 and the threaded rod Ⅱ406 is located in the key groove 4041 at the same time, and then the motor drives the gear 401 to rotate and mesh with the gear ring 402, and drives the threaded rod Ⅰ4 and the threaded rod Ⅱ406 to rotate at the same time. Since the thread grooves on the surfaces of the threaded rod Ⅰ4 and the threaded rod Ⅱ406 are opposite, the two slide seats Ⅰ When 301 slides on the surface of the machine body 1, the sliding directions are also relative and all move toward the direction close to the flip plate 2. When the slide seat Ⅰ301 continuously moves toward the flip plate 2, the flip plate 2 is continuously flipped into a vertical state through the support frame 3 located inside the slide groove Ⅰ201. At this time, the support frame 3 is tilted and supported on the surface of the flip plate 2. When a workpiece on the surface of one flip plate 2 is flipped and located on the surface of another flip plate 2, the support of the support frame 3 on the surface of the flip plate 2 can buffer the impact force of the workpiece when it is flipped to the surface of the other flip plate 2, thereby avoiding the fracture of the bottom of the flip plate 2 and affecting the subsequent processing.

[0038] When the sliding rod 403 moves in the direction away from the threaded rod I4, and the plug block 405 on the inner wall of the threaded rod I4 and the threaded rod II 406 is located in the annular slot 4042, the threaded rod I4 can be rotated independently, and the flipping angle of the other flip plate 2 can be adjusted, thereby expanding the inclination angle of the other flip plate 2, so as to prevent the workpiece from slipping when placed on the other flip plate 2.

[0039] Embodiment 2

[0040] See also Figure 8-11 As shown, as a specific embodiment of the present invention, filling pieces 4051 are slidably connected to the inner sides of the lower surface of the plug block 405 through connecting shafts 4052, the surface of the filling piece 4051 is elastically connected to the lower surface of the plug block 405 through spring III, the top of one side of the filling piece 4051 is in the shape of an arc, a spring II 4054 is fixed to the bottom of the plug block 405, the bottom of the spring II 4054 is fixedly connected to the bottom of the plug block 405, and inclined blocks 4053 are fixedly connected to the two sides of the plug block 405. When the lower end of the plug block 405 descends, the connecting shaft 4052 contacts the inclined block 4053 to expand outwards on both sides of the plug block 405 and contact the two side walls of the key groove 4041, so as to prevent the threaded rod I4 from stopping or rotating synchronously with the movement state of the threaded rod I4 due to the gap between the key groove 4041 and the plug block 405 when the rotation stops.

[0041] On the basis of the first embodiment, when the adjustment component 404 moves toward the direction close to the gear ring 402 through the sliding rod 403, the telescopic part at the bottom of the plug block 405 is stuck in the key groove 4041, and the bottom of the plug block 405 is pushed down by the deformation expansion generated by the spring II 4054, and at the same time drives its filling piece 4051 to descend at the same time. When the filling piece 4051 descends, when the end of the connecting shaft 4052 contacts the inclined surface of the inclined block 4053, the filling piece 4051 moves outward on both sides of the plug block 405 and contacts the inner wall of the key groove 4041 without gaps, filling the space of the key groove 4041, which can avoid the rotation instability of the threaded rod I4 or the threaded rod II 406 due to the gap during rotation. Therefore, it is more labor-saving during rotation and can accurately determine the rotation angle of the threaded rod I4 and the threaded rod II 406, so as to facilitate the stable support of the support frame 3 on the surface of the flip plate 2.

[0042] Embodiment 3

[0043] See also Figure 5-7 As shown, as a specific embodiment of the present invention, a clamping mechanism is provided on the upper surface of the flip plate 2, and the clamping mechanism includes a clamping frame 304 and a lifting rod 303. The clamping mechanism can quickly clamp the flipped workpiece so that it is stably located on the surface of the flip plate 2, so as to prevent the workpiece from sliding down due to the slope when the other flip plate 2 is gradually laid flat to a horizontal state;

[0044] A clamping roller 3031 is rotatably installed on the bottom of one side of the lifting rod 303 and located above the clamping frame 304 through a slider 3032. The clamping frame 304 is fixed on the upper surface of the flip plate 2. The lifting rod 303 is lifted and installed on the top of the flip plate 2. A push plate 305 is slidably connected to the surface of the clamping frame 304. A sliding shaft 3051 that passes through two slide grooves Ⅰ201 is fixedly connected to the surface of the push plate 305. A roller 3052 is rotatably connected to the surface of the sliding shaft 3051. An oblique groove 3034 is opened on the surface of the lifting rod 303. The roller 3052 is located in the oblique groove 3034 and translates. When the support frame 3 slides inside one of the slide grooves Ⅰ201, it contacts the end of the sliding shaft 3051 and pushes the push plate 305 to translate on the surface of the clamping frame 304 to push its workpiece to the surface of another flip plate 2.

[0045] On the basis of the first embodiment, when the slide II 302 moves toward the direction close to the flip plate 2, the support frame 3 continuously rises inside the flip plate 2 through the slide groove I 201. When the top of the support frame 3 contacts the sliding shaft 3051, it pushes the sliding shaft 3051 and the push plate 305 to move toward the other flip plate 2. When the sliding shaft 3051 moves toward the direction close to the other flip plate 2, the roller 3052 moves to the right inside the oblique groove 3034. At this time, the lifting rod 303 rises upward to prevent the top of the workpiece from being blocked when it flips to the surface of the other flip plate 2.

[0046] The push plate 305 is used to push the workpiece toward the surface of the other flip plate 2 and flip it closer. When the workpiece is located on the surface of the other flip plate 2, the workpiece contacts the push plate 305, and the push plate 305 moves toward the inside of the flip plate 2 under the pressure of the workpiece. At this time, the roller 3052 is located on the surface of the oblique groove 3034 and moves in the same direction to lower the height of the lifting rod 303. The clamping roller 3031 rolls a single circle on the surface of the workpiece to clamp and fix it when flipping to the surface of the other flip plate 2, so as to avoid the workpiece from sliding due to its own gravity when flipping to the other flip plate 2, and facilitate the stable flipping and dumping of the workpiece.

[0047] The surface of the clamping roller 3031 is covered with a friction pad, and the clamping roller 3031 can only rotate in a single circle. One end of the slider 3032 is elastically slidably connected to the end face of the lifting rod 303 through an elastic member, and a fixing block 3037 is fixedly connected to the inner wall of one of the slide grooves Ⅰ201. A spring Ⅰ3036 is fixedly connected to the bottom of the lifting rod 303 and located inside the slide groove Ⅰ201, and the bottom of the spring Ⅰ3036 is connected to the fixing block 3037; both ends of the lifting rod 303 are rotatably connected with a card 3033, and a card block is provided on the inner wall of the slider 3032. A compression spring is provided in the card 3033 to fix the angle opened by the card 3033 so that the card 3033 and the card block can be correspondingly engaged.

[0048] By setting the friction pad on the surface of the clamping roller 3031 and the single-circle rotation of the clamping roller 3031, the friction force between the friction pad and the workpiece can be increased to further fix it when it is flipped. Since the workpiece has a certain thickness, when the clamping roller 3031 is located on the surface of the workpiece, the clamping roller 3031 moves horizontally at the end of the lifting rod 303, and the upper and lower ends of the card 3033 engage with the card block to fix its movement angle. The clamping thickness can be automatically adjusted according to the thickness of the workpiece, which is convenient for using workpieces of different thicknesses and fixing them at the same time.

[0049] It should be noted that, in this article, relational terms such as first and, second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
