The both ends of connecting rod 4 are rotatably connected with rectangular frame 1 and workpiece clamping assembly 5 respectively, workpiece clamping assembly 5 is rotatably connected on rectangular frame 1 through connecting rod 4, and workpiece is turned over in the process of rotating workpiece clamping assembly 5.

[0026] As Figures 1-3 Shown, workpiece clamping assembly 5 includes cross bar 6, and a pair of second connecting column 9 is slidably connected on cross bar 6, and connecting lug 10 is fixedly connected on the side wall close to rectangular frame 1 of second connecting column 9, and third connecting column 1001 is fixedly connected on connecting lug 10, and the first connecting column 2 matched with third connecting column 1001 is fixedly connected on rectangular frame 1, and the both ends of connecting rod 4 are respectively provided with the first through hole 401 matched with first connecting column 2 and third connecting column 1001. That is, connecting rod 4 is rotatably connected with first connecting column 2 and third connecting column 1001 through first through hole 401, and in the process of rotating, due to the existence of first through hole 401, workpiece clamping assembly 5 can be rotated, and the height of workpiece clamping assembly 5 can be changed.

[0027] It is worth noting that damping structure should be arranged between first through hole 401 and first connecting column 2, third connecting column 1001 and first through hole 401, so that workpiece can be locked after being installed on workpiece clamping assembly 5 and being turned over. The damping structure can be damping bearing, which is well known to those skilled in the art, and will not be described in detail in the embodiment.

[0028] As Figures 1-3 Shown, the second through hole 602 matched with second threaded hole 901 is formed in the second connecting column 9, and the second through hole 602 matched with second threaded hole 901 is formed in cross bar 6, and the bidirectional screw rod 7 matched with second through hole 602 is rotatably connected on cross bar 6, and the bidirectional screw rod 7 is screwedly connected with second threaded hole 901. That is, the bidirectional screw rod 7 is rotatably connected with cross bar 6, and in the process of rotating bidirectional screw rod 7, the distance between the two second connecting columns 9 changes by moving away from each other or moving close to each other. One end of bidirectional screw rod 7 is also fixedly connected with first handle 8, which facilitates the rotation of bidirectional screw rod 7.

[0029] Further, as Figures 1-3As shown, the second connecting column 9 is provided with a plug-in slot 902, the plug-in slot 902 is provided on the opposite surface of the second connecting column 9, and the plate-shaped workpiece is placed in the two plug-in slots 902. By changing the distance between the two plug-in slots 902, the plug-in slot 902 can be clamped with a larger size plate-shaped workpiece, which is beneficial to clamping and turning over different sizes of plate-shaped workpieces.

[0030] As shown in the figure, Figures 1-3 In order to make the plug-in slot 902 adapt to plate-shaped workpieces of different thicknesses, a sleeve 11 matched with the plug-in slot 902 is installed on the second connecting column 9, the sleeve 11 is provided with an internal thread 1101 penetrating the upper wall of the plug-in slot 902, and the sleeve 11 is internally threadedly connected with a first screw rod 12 matched with the internal thread 1101. The upper end of the first screw rod 12 is fixedly connected with a second handle 13, and the lower end of the first screw rod 12 is fixedly connected with a rubber block 14 located in the plug-in slot 902. When the first screw rod 12 rotates in the internal thread 1101, the distance between the rubber block 14 and the plate-shaped workpiece can be controlled. By tightening the first screw rod 12 and making the rubber block 14 contact with the plate-shaped workpiece, the plate-shaped workpiece can be fastened, and in the process of turning over, the plate-shaped workpiece is prevented from being separated from the first screw rod 12 as much as possible.

[0031] In order to make the workpiece clamping assembly 5 regularly turn over on the rectangular frame 1, and be able to lock at any position of turning over, and make the locked workpiece clamping assembly 5 be able to bear a certain force, as shown in the figure, Figures 1-3 The rectangular frame 1 is fixedly connected with a first protruding part 3, the first protruding part 3 is provided with a first threaded hole 301, the first protruding part 3 is threadedly connected with a driving assembly 15 matched with the first threaded hole 301, one end of the driving assembly 15 is rotatably connected with the workpiece clamping assembly 5, and the end of the driving assembly 15 away from the workpiece clamping assembly 5 is fixedly connected with a third handle 18. When the driving assembly 15 rotates, it can pull the workpiece clamping assembly 5 to move towards or away from the first protruding part 3, and when the workpiece clamping assembly 5 moves towards the end of the first protruding part 3, the first connecting column 2 and the connecting rod 4 cooperate to make the workpiece clamping assembly 5 rotate upwards to realize the turning over of the workpiece.

[0032] The first threaded hole 301 can be a through hole, when the first threaded hole 301 is a through hole, the driving assembly 15 needs to be pulled away from the workpiece clamping assembly 5 to make the workpiece clamping assembly 5 turn over, and after pulling the driving assembly 15, the driving assembly 15 needs to be locked.

[0033] Specifically, as shown in the figure, Figures 1-3As shown, the driving assembly 15 comprises a first connecting part 16 and a second screw rod 17, the first connecting part 16 and the second screw rod 17 are rotationally connected, the first connecting part 16 is L-shaped, a pair of connecting plates 603 are fixedly connected on the horizontal rod 6, the pair of connecting plates 603 are located at the middle part of the horizontal rod 6, the first connecting part 16 is located between the pair of connecting plates 603, and the first connecting part 16 is rotationally connected with the connecting plates 603.

[0034] As shown in the figure, Figures 1-4 The second screw rod 17 is provided with a limiting convex part 1701 on the opposite surface of the first connecting part 16, and the first connecting part 16 is fixedly connected with a limiting groove 1601 matched with the limiting convex part 1701. The first connecting part 16 and the second screw rod 17 are rotationally connected through the limiting groove 1601 and the limiting convex part 1701, the second screw rod 17 is threadedly connected with the first threaded hole 301, and when the second screw rod 17 rotates, the workpiece clamping assembly 5 can be pulled to overturn the workpiece clamping assembly 5, and when the second screw rod 17 stops rotating, the workpiece clamping assembly 5 can be locked at the current overturning position.

[0035] As shown in the figure, Figures 1-3 The second screw rod 17 is fixedly connected with a third handle 18 at the end away from the first connecting part 16, and the third handle 18 can be conveniently rotated through the second screw rod 17.

[0036] In use, first of all, the width of the plate-shaped workpiece needs to be determined, the first handle 8 is rotated according to the determined width, the bidirectional screw rod 7 is rotated with the first handle 8, the second connecting column 9 slides in the sliding groove 601 in the process of rotating the bidirectional screw rod 7, until the plate-shaped workpiece can be clamped between the two insertion grooves 902. Then the plate-shaped workpiece is inserted into the insertion groove 902, and the second handle 13 is twisted to make the rubber block 14 tightly contact with the surface of the plate-shaped workpiece, so that the rubber block 14 extrudes and fixes the plate-shaped workpiece. After the processing of one side of the plate-shaped workpiece is completed, the third handle 18 is rotated to move the third handle 18 away from the workpiece clamping assembly 5, the workpiece clamping assembly 5 overturns with the moving distance of the third handle 18, and can overturn 180°, and the third handle 18 can be stopped rotating at any time in the process of overturning, and the workpiece clamping assembly 5 can also be locked. The plate-shaped workpiece is processed in the inclined state of the workpiece clamping assembly 5. After the processing of the plate-shaped workpiece is completed, the second handle 13 is twisted to move the rubber block 14 away from the plate-shaped workpiece, and the plate-shaped workpiece can be taken out.
