Detailed implementation

[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.

[0020] See Figure 1 to Figure 4 , a turning device for processing metal workpieces, comprising: Frame 1; Turning unit 2, rotatably connected to the frame 1, for turning the metal workpiece; Fixing unit 3, slidably connected to both side surfaces of the turning unit 2, for limiting and fixing the metal workpiece in the turning unit 2; Convex unit 4, connected to the turning unit 2 and slidably connected to the two fixing units 3, for cooperating with the turning unit 2 to realize the reverse sliding of the two fixing units 3 on the two surfaces of the turning unit 2; Clamping unit 6, one end slidably connected to the inside of the turning unit 2, and the other end connected to the convex unit 4, for cooperating with the convex unit 4 to realize the clamping and fixing of the metal workpiece in the turning unit 2; Processing unit 5, rotatably connected to the frame 1, for processing the metal workpiece in the turning unit 2.

[0021] In one embodiment of the present invention, when processing a metal workpiece, the metal workpiece is placed in the flipping unit 2, and the processing unit 5 is turned on so that the processing unit 5 can process the metal workpiece. The flipping unit 2 is turned on, and the flipping unit 2 can drive the metal workpiece to flip, and the fixing unit 3 and the clamping unit 6 can automatically limit and clamp the metal workpiece in cooperation with the flipping unit 2 and the convex unit 4, thereby improving the processing accuracy and efficiency.

[0022] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the flipping unit 2 comprises: The first bracket 21 is connected to the frame 1 and has a driving member 23 mounted on the side thereof; A driving rod 22 is rotatably connected to the first bracket 21, and an end portion is connected to an output end of the driving member 23; A rotating rod 24, one end of which is connected to the end of the driving rod 22 away from the driving member 23, and the other end of which is fixed with a processing table 25; The radiation frame 26 is fixed inside the processing table 25, and has at least one group of processing holes on its surface.

[0023] In this embodiment, when processing a metal workpiece, the metal workpiece is first placed on the radiation rack 26 on the surface of the processing table 25, and the processing unit 5 is turned on so that the processing unit 5 can process the metal workpiece on the processing table 25.

[0024] When it is necessary to turn over the metal workpiece on the processing table 25, the driving member 23 is turned on, and the output end of the driving member 23 can drive the driving rod 22 to rotate. When the driving rod 22 rotates, it can drive the processing table 25 at its end to rotate through the rotating rod 24. When the processing table 25 drives the metal workpiece to rotate 180 degrees, the driving member 23 can be turned over to facilitate processing on both sides of the metal workpiece.

[0025] like Figure 1 As shown, the radiation frame 26 is a hexagonal radiation frame. In the on-site device, the radiation frame 26 can also be a three-sided radiation frame, and at least one group of processing holes is opened on the radiation frame 26. Therefore, when the processing table 25 drives the metal workpiece to turn over, the other side of the metal workpiece can be processed through the gap and processing holes of the radiation frame 26.

[0026] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the fixing unit 3 includes: The rotating shaft 33 is rotatably connected to the processing table 25, and a clamping frame 34 is installed on the surface. The clamping frame 34 is installed in two groups, and the surfaces of the two groups of the clamping frames 34 are rotatably connected to the two side surfaces of the processing table 25 respectively; The sliding frame 31 is slidably connected to the two side surfaces of the processing table 25. Two sets of inclined grooves 32 are opened at the ends of the sliding frame 31. One end of the clamping frame 34 is slidably connected to the surface of the inclined groove 32. An arc groove 35 is provided on the clamping frame 34; The limiting frame 36 is fixed on the side of the processing table 25 , and the side of the limiting frame 36 is connected to the inner wall of the arc groove 35 through an elastic member.

[0027] In this embodiment, if Figure 2 or Figure 3 As shown, in the process of turning over the processing table 25, the sliding frame 31 on the lower side of the processing table 25 will slide on the surface of the processing table 25 toward the radiation frame 26 under the action of the convex unit 4, and the sliding frame 31 can drive the two groups of inclined grooves 32 at its end to slide synchronously when sliding. When the two groups of inclined grooves 32 slide to contact the ends of the two groups of clamping frames 34 on the lower side of the processing table 25, the two groups of clamping frames 34 will respectively drive the corresponding rotating shafts 33 to rotate on the processing table 25 under the push of the two groups of inclined grooves 32, so that the two groups of clamping frames 34 on the lower side of the processing table 25 away from the end of the sliding frame 31 are close to each other, and the clamping frame 34 can drive the arc groove 35 on its surface to rotate synchronously during the rotation process, so that the arc groove 35 can compress the elastic member inside it. At the same time, the sliding frame 31 on the lower side of the processing table 25 also slides in the direction close to the radiation frame 26 until the two sets of clamping frames 34 and the sliding frame 31 on the lower side of the processing table 25 slide to the lower side surface of the metal workpiece (such as Figure 2 , Figure 3 Therefore, the metal workpiece on the lower side of the radiating frame 26 in the processing table 25 will be limited by the joint clamping of the two sets of clamping frames 34 and the sliding frame 31, and the upper surface of the metal workpiece can be processed from above through the gap of the radiating frame 26 and the processing holes on the surface of the radiating frame 26.

[0028] like Figure 1 As shown, the slide frame 31 on the upper side of the processing table 25 will slide on the surface of the processing table 25 in a direction away from the radiation frame 26 under the action of the convex unit 4. At this time, the two groups of arc grooves 35 will drive the corresponding rotating shafts 33 to rotate in opposite directions on the processing table 25 through the two groups of clamping frames 34 under the elastic force of the elastic members inside them, so that the ends of the two groups of clamping frames 34 on the upper side of the processing table 25 away from the slide frame 31 are separated from each other, and at the same time, the slide frame 31 on the upper side of the processing table 25 also slides in a direction away from the radiation frame 26 until the two groups of clamping frames 34 and the slide frame 31 slide to the upper side surface of the metal workpiece (as shown in FIG. Figure 1 In the state of (), the metal workpiece on the upper side of the radiation rack 26 in the processing table 25 can be processed from above.

[0029] In an embodiment of the present invention, as Figure 2 and Figure 3 shown, the convex unit 4 includes: A second bracket 41, connected to the frame 1, with a runner 411 rotatably connected inside, and the center of the runner 411 is installed on the surface of the rotating rod 24; An L-shaped frame 42, slidably connected inside the runner 411, and two sets of L-shaped frames 42 are installed, and the ends of the two sets of L-shaped frames 42 are respectively connected to the two sliding frames 31; A C-shaped frame 43, fixed to the end of the L-shaped frame 42 away from the sliding frame 31, and the C-shaped frame 43 is connected to the runner 411 through an elastic object; A fixing ring 45, fixed to the side of the first bracket 21, with a convex portion 46 provided at the end, and the convex portion 46 is located at the lowest position of the fixing ring 45; A rotating column 44, rotatably connected inside the C-shaped frame 43, and the rotating column 44 is respectively in rolling connection with the surfaces of the fixing ring 45 and the convex portion 46.

[0030] In this embodiment, when the rotating rod 24 rotates, it can drive the runner 411 on its surface to rotate synchronously inside the second bracket 41. At the same time, the runner 411 will also drive the two sets of L-shaped frames 42 inside it to rotate. Therefore, the L-shaped frames 42 will respectively drive the sliding frames 31 and the C-shaped frames 43 at their two ends to rotate.

[0031] When a set of L-shaped frames 42 (hereinafter denoted as the first L-shaped frame 42) rotates to the lowest point, at this time, the first L-shaped frame 42 will drive the sliding frame 31 at one of its ends to rotate to the lower surface of the processing table 25, and the C-shaped frame 43 at the other end of the first L-shaped frame 42 will slide onto the convex portion 46 directly below the fixing ring 45. Therefore, the C-shaped frame 43 will push the first L-shaped frame 42 to slide in the runner 411 in the direction close to the radiation rack 26 under the action of the convex portion 46. When the C-shaped frame 43 slides, it will compress the elastic object, and when the first L-shaped frame 42 slides, it will drive the sliding frame 31 at its end to slide synchronously until the inclined grooves 32 at both ends of the sliding frame 31 slide to contact the ends of the two clamping frames 34 on the lower side of the processing table 25. The two clamping frames 34 will respectively drive the corresponding rotating shafts 33 to rotate on the processing table 25 under the push of the two inclined grooves 32, so that the ends of the two clamping frames 34 on the lower side of the processing table 25 away from the sliding frame 31 approach each other until the two clamping frames 34 and the sliding frame 31 on the lower side of the processing table 25 all slide to the lower surface of the metal workpiece (as Figure 3The state). Therefore, the metal workpiece on the lower side of the radiation rack 26 will be limited by the combined clamping of the two groups of clamping racks 34 and the sliding rack 31. At this time, the metal workpiece can be processed from above through the gap of the radiation rack 26 and the processing holes on the radiation rack 26.

[0032] When the first L-shaped frame 42 rotates to the lowest point, the other group of L-shaped frames 42 (hereinafter referred to as the second L-shaped frame 42) rotates to the highest point at this time. Therefore, the C-shaped frame 43 at the end of the second L-shaped frame 42 also rotates to the highest point at this time. As a result, this group of C-shaped frames 43 will drive the second L-shaped frame 42 to slide in the runner 411 in the direction close to the fixed ring 45 under the elastic force of the elastic object. When the second L-shaped frame 42 slides, it will drive the sliding rack 31 at its end to slide synchronously. Therefore, at this time, the two arc-shaped grooves 35 will drive the corresponding rotating shafts 33 to rotate in the opposite direction on the processing table 25 under the elastic force of the elastic parts inside them through the two groups of clamping racks 34, so that the ends of the two groups of clamping racks 34 on the upper side of the processing table 25 that are far away from the sliding rack 31 move away from each other until both the two groups of clamping racks 34 and the sliding rack 31 slide to脱离 the upper surface of the metal workpiece (such as Figure 1 The state), which is convenient for processing the metal workpiece on the upper side of the radiation rack 26 from above.

[0033] Both the elastic object and the elastic part can be a spring or elastic rubber, and no unique limitation is made here. Further, a rotating column 44 is rotatably connected inside the C-shaped frame 43, and the rotating column 44 is respectively in rolling connection with the fixed ring 45 and the convex part 46, thereby improving the smoothness of the C-shaped frame 43 sliding on the surfaces of the fixed ring 45 and the convex part 46.

[0034] In an embodiment of the present invention, as Figure 1 shown, the clamping unit 6 includes: A piston cylinder 61, fixed on the surface of the runner 411, with a sliding part slidably connected inside it, and a sliding rod 62 fixed at the end of the sliding part; A fixed disk 64, fixed on the side of the second bracket 41, with its surface slidably connected to the end of the sliding rod 62; A groove 65, opened inside the processing table 25, with at least three air bags 66 installed inside it, and the air bags 66 are communicated with the piston cylinder 61 through an air duct 63.

[0035] In this embodiment, when the runner 411 rotates, it can drive the sliding rod 62 inside it to rotate synchronously through the piston cylinder 61. As Figure 1As shown, when the L-shaped frame 42 rotates to the lowest point, the rotating wheel 411 drives the sliding rod 62 to rotate until it contacts the fixed plate 64 through the piston cylinder 61, so the sliding rod 62 will push the sliding part to slide in the piston cylinder 61 under the action of the fixed plate 64, thereby reducing the space inside the piston cylinder 61, and then the air inside the piston cylinder 61 will be compressed into the airbag 66 through the air guide tube 63, causing the airbag 66 to expand, and the gap between the surface of the metal workpiece and the inner wall of the radiation frame 26 will be filled with the expanded airbag 66, thereby improving the stability of the metal workpiece on the lower side of the radiation frame 26, and facilitating the processing of the metal workpiece by the processing unit 5.

[0036] When the L-shaped frame 42 rotates to the highest point, the rotating wheel 411 drives the sliding rod 62 to rotate to the surface of the fixed plate 64 through the piston cylinder 61, so the gas in the airbag 66 will flow back to the piston cylinder 61 through the air guide tube 63, thereby reducing the volume of the airbag 66, making it easier to remove the processed metal workpiece from the radiation frame 26.

[0037] In one embodiment of the present invention, Figure 4 As shown, the processing unit 5 includes: The support frame 51 is fixed on the frame 1 and is rotatably connected to the support frame 52 at the side; The gear ring 53 is slidably connected to the inside of the support frame 52; A rotating rod 54 is rotatably connected in the supporting frame 52, and a gear 55 is mounted on the surface thereof, and the gear 55 is meshingly connected with the gear ring 53; A first driver 56 is installed on the side of the support frame 52, and the end of the rotating rod 54 is connected to the output end of the first driver 56; A fixing frame 57 is connected to the inner wall of the gear ring 53, and a processing part 59 is installed on the side through a telescopic rod 58; The second driver 510 is installed on the side of the support frame 51 , and the output end of the second driver 510 is connected to the support frame 52 .

[0038] In this embodiment, when processing a metal workpiece, the telescopic rod 58 and the processing piece 59 are opened, and the telescopic rod 58 drives the processing piece 59 to extend. The processing piece 59 can be processed by an electric welder or a grinder to facilitate processing of the metal workpiece.

[0039] When the first driver 56 is turned on, the output end of the first driver 56 drives the rotating rod 54 to rotate in the support frame 52. When the rotating rod 54 rotates, it can drive the gear 55 on its surface to rotate synchronously. Since the gear 55 and the gear ring 53 are meshed and connected, the gear ring 53 slides in the support frame 52 under the action of the gear 55. When the gear ring 53 rotates, it can drive the fixed frame 57 to rotate synchronously. Therefore, the fixed frame 57 drives the processing part 59 to rotate through the telescopic rod 58, so as to facilitate the adjustment of the processing angle of the processing part 59.

[0040] When the second driver 510 is turned on, the output end of the second driver 510 will drive the support frame 52 to rotate on the surface of the support frame 51. When the support frame 52 rotates, it will drive the fixed frame 57 to adjust the angle through the gear ring 53, so that the fixed frame 57 will drive the processing part 59 to rotate through the telescopic rod 58. Through the cooperation of the first driver 56 and the second driver 510, the processing angle of the processing part 59 can be fully adjusted, thereby improving the processing accuracy of the metal workpiece. The first driver 56, the second driver 510 and the driving member 23 can all adopt electric motors or pneumatic motors, which are not limited here.

[0041] The working principle of the present invention is: when processing a metal workpiece, the metal workpiece is placed on the radiating frame 26 on the surface of the processing table 25, and the processing unit 5 is turned on so that the processing unit 5 can process the metal workpiece on the processing table 25. The driving member 23 is turned on, so that the processing table 25 can drive the metal workpiece to turn over. In the process of turning over the processing table 25, the sliding frame 31 on the lower side of the processing table 25 will slide on the surface of the processing table 25 toward the radiating frame 26 under the action of the convex unit 4, and at the same time, the two groups of clamping frames 34 on the lower side of the processing table 25 will move closer to each other until the two groups of clamping frames 34 and the sliding frame 31 on the lower side of the processing table 25 slide to the lower side surface of the metal workpiece. Therefore, the metal workpiece on the lower side of the radiating frame 26 will be limited under the joint clamping of the two groups of clamping frames 34 and the sliding frame 31, and at this time, the upper side surface of the metal workpiece can be processed through the processing holes on the surface of the radiating frame 26.
