DETAILED DESCRIPTION

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a workpiece lifting and clamping synchronization mechanism includes a workbench 1 and a base 2 arranged on the workbench 1, the workbench 1 is provided with a through hole 11, the workbench 1 is provided with a fixing mechanism 3 for fixing the workpiece 7, a lifting and clamping component 4 for lifting the workpiece 7 and laterally clamping the workpiece 7 is movably connected in the through hole 11, and a power source 5 connected to the lifting and clamping component is provided on the base 2. The power source 5 in this embodiment can be a cylinder or an electric cylinder, which can be installed according to actual needs. Secondly, the number of bases 2 in this embodiment can be selected and installed according to actual needs, which can meet the needs of lifting and clamping multiple workpieces 7 at the same time.

[0025] The lifting and clamping assembly 4 is moved in the through hole 11 by the power source 5. Since the lifting and clamping assembly 4 can lift the workpiece 7 and clamp the workpiece 7 laterally at the same time, only one power source 5 is needed to simultaneously lift and clamp the workpiece 7. No additional power is required to achieve the clamping action, thereby reducing and saving the installation space of the power source 5 on the workbench 1. Moreover, the entire structure is flexible and changeable and can adapt to workpieces 7 of different specifications. Secondly, since the fixing mechanism 3 can fix the workpiece 7 on the workbench 1 during jacking, the stability of the workpiece 7 can be effectively guaranteed, and the outward lateral movement of the workpiece 7 during the jacking process can be avoided, thereby improving the jacking efficiency. Finally, multiple lifting and clamping assemblies 4 can be installed on the workbench to meet the synchronous jacking and clamping operations of multiple workpieces 7, further improving the production efficiency.

[0026] The jacking and pressing assembly 4 includes a push block 41, a jacking block 42, a connecting block 43 and a pressure head 44. The bottom end of the connecting block 43 is fixedly connected to the push block 41, and the other end of the connecting block 43 is movably connected to the jacking block 42. The pressure head 44 is movably connected to the jacking block 42. The push block 41 is connected to the power source 5. When the power source 5 moves upward, the connecting block 43 drives the jacking block 42 to be lifted and drives the pressure head 44 to move laterally. When the present embodiment is in operation, the power source 5 drives the push block 41 to move upward, the push block 41 drives the connecting block 43 to rise synchronously, the connecting block 43 drives the jacking block 42 to be lifted and drives the pressure head 44 to move laterally, which can improve the jacking and pressing efficiency.

[0027] The connecting block 43 is provided with a first slide groove 45 which is inclined upward, the lifting block 42 is provided with a moving shaft 46 which cooperates with the first slide groove 45, the lifting block 42 is provided with a second slide groove 47 which cooperates with the moving shaft 46, and the pressing head 44 is provided with a moving shaft 46. The setting of the first slide groove 45 enables the moving shaft 46 to slide downward along the first slide groove 45 when the connecting block 43 is rising, and the moving shaft 46 drives the pressing head 44 to slide in the second slide groove 47 during the sliding process, thereby achieving the lifting of the lifting block 42 and the outward sliding of the pressing head 44 at the same time. The structure is simple and the installation and disassembly are convenient. The first slide groove 45 and the second slide groove 47 can ensure the smooth sliding of the moving shaft 46.

[0028] The pressing head 44 includes a sliding section 441 movably connected to the lifting block 42, and a crimping section 442 for pressing the workpiece 7. The sliding section 441 is provided with a connecting hole 443 connected to the moving shaft 46, and the lifting block 42 is provided with a through groove 421 matched with the sliding section 441. The pressing head 44 is arranged into the sliding section 441 and the crimping section 442, so that the sliding and crimping operations can be realized independently. Specifically, when the moving shaft slides downward along the first slide groove, the moving shaft slides along the second slide groove and drives the sliding shaft 46 to move downward. The movable section moves in the lifting block, thereby realizing the crimping action of the crimping section. The sliding section 441 and the crimping section 442 in this embodiment can be set as an integrated structure, or can be set as a separate structure such as a bolt connection. The setting of the connecting hole 443 can ensure the installation and fixation of the moving shaft 46, and ensure that the sliding section 441 can be driven to slide in the through groove 421 during the lifting process. The through groove can ensure the straightness of the sliding section, thereby improving the clamping quality. Both ends of the crimping section 442 in this embodiment are provided with arc extrusion parts, which can improve the clamping effect. The lifting block 42 is provided with a groove 422 for fixing the connecting block 43, which can axially limit the connecting block 43 and improve the stability of the lifting and pressing action. The push block 41 is also provided with a vertical slide 48, and the base 2 is provided with a vertical slide 21 adapted to the vertical slide 48, which can ensure the straightness of the push block 41 and ensure the stability of the lifting of the lifting block 42. The base 2 is also provided with a threaded column 26, a spring 27 arranged on the screw column, and a nut 28 arranged on the threaded column 26. A limit stopper 29 is provided on the vertical sliding block, and the spring 27 is located between the limit stopper 29 and the bottom of the mounting seat. A travel limit groove 20 cooperating with the limit stopper 29 is provided on the base 2. By adjusting the distance that the nut 28 is screwed into the threaded column 26, the stroke adjustment of the rising stroke of the vertical slide plate 48 can be achieved, thereby achieving the stroke adjustment of the extrusion distance of the extrusion head 44. The setting of the travel limit groove 20 can play a role of limiting the maximum stroke and the minimum stroke of the limit stopper 29 through the travel limit groove 20.

[0029] The fixing assembly includes a limit frame 31 and an abutment plate 32 arranged on the limit frame 31. The limit frame 31 is detachably installed on the workbench 1, and the distance between the limit frame 31 and the workpiece 7 can be adjusted by the abutment block, so that it is suitable for workpieces 7 of various sizes. The limit frame 31 is arranged to be detachably installed, and a limit frame 31 of different thicknesses can be selected according to different workpieces 7, thereby improving the overall strength of the limit frame 31 and preventing lateral movement of the workpiece 7 during the jacking process. The limit frame 31 includes a horizontal portion 33 and a vertical portion 34, and a reinforcing plate 35 is further arranged between the horizontal portion 33 and the vertical portion 34. The abutment plate 32 is arranged on both the horizontal portion 33 and the vertical portion 34. The limit frame 31 is arranged as a horizontal portion 33 and a vertical portion 34, so that synchronous limiting in the horizontal and vertical directions can be achieved, thereby ensuring the stability of the workpiece 7. The arrangement of the reinforcing plate 35 further improves the connection strength of the entire limit frame 31.

[0030] The workbench 1 is provided with a pad 6 for adjusting the height of the workpiece 7, which can effectively adjust the height of the workpiece 7 to meet different tool requirements. The pad 6 in this embodiment can be installed on the workbench 1 by screws. The base 2 includes a bottom plate 22, a first vertical plate 23 and a second vertical plate 24. The first vertical plate 23 is arranged at one end of the bottom plate 22, and the second vertical plate 24 is arranged at the other end of the bottom plate 22. The power source 5 is arranged on the bottom plate 22. The first vertical plate 23 and the second vertical plate 24 are both provided with a flange 25 connected to the workbench 1. The flange 25 can realize the rapid installation of the base 2 on the workbench 1. The flange 25 in this embodiment can be fixedly connected to the workbench 1 by bolts or magnets. The bottom plate 22 can increase the contact area between the base 2 and the power source 5, and can provide certain support to the power source 5 to ensure the stable movement of the power source 5.
