Description

Technical Field

[0001] This utility model relates to the field of non-standard welding special machine technology, and in particular to a workpiece clamping mechanism for a non-standard welding special machine. Background Technology

[0002] Non-standard welding robots, also known as non-standard welding equipment, are automated equipment designed specifically for special welding needs. They are mainly used in fields such as large hardware processing parts, shipbuilding, truck body welding, and steel structure production where standard robots cannot adapt.

[0003] Currently, non-standard welding machines on the market typically require a clamping mechanism to clamp and fix the workpiece during welding operations to improve the stability of the welding process. A positioning device for a welding machine, patent number CN202322110435.9, includes: a base mounted on the welding machine; and a positioning assembly comprising a rotatable drive shaft and a driven shaft, the drive shaft being slidably disposed within the base, the driven shaft being located below the drive shaft, and a drive bevel gear being mounted on the drive shaft. Its structure is simple. However, traditional clamping mechanisms can only clamp one workpiece at a time. After welding a single workpiece, the clamping must be released, the workpiece removed, and a new workpiece placed on the worktable, clamped again, and then the subsequent welding operation performed. During the aforementioned material handling, loading, and clamping processes, the welding operation needs to be stopped, resulting in low welding efficiency.

[0004] Therefore, this application proposes a workpiece clamping mechanism for a non-standard welding special machine. Utility Model Content

Electric push rods are fixedly installed on the top of the inner walls of each of the four side frames, and pressure plates are fixedly connected to the bottom of the electric push rods. A side groove is opened on one side of the outer wall of the fixed plate, and a servo motor is fixedly installed on the other side of the outer wall of the fixed plate. A screw is fixedly connected to the output end of the servo motor. A connecting plate is fixedly connected to the bottom of the movable plate, and one side of the connecting plate extends into the cavity of the side groove. One end of the screw passes through the outer wall of the fixed plate and the connecting plate, and is threadedly connected to the connecting plate. The screw is rotatably connected to the outer wall of the fixed plate.

[0009] Preferably, two limiting rods are fixedly connected to the inner wall of the through groove, and two limiting holes are opened on the movable plate, with the two limiting rods passing through the corresponding limiting holes respectively.

[0010] Preferably, the inner diameter of the limiting hole is the same as the outer diameter of the limiting rod.

[0011] Preferably, a fixing frame is fixedly installed on the outer wall of the servo motor, and the fixing frame is fixedly connected to the outer wall of the fixing plate.

[0012] Preferably, a fixing seat is sleeved and fixedly installed on the outer wall of the electric actuator, and the fixing seat is fixedly connected to the top of the inner wall of the side frame.

[0013] Preferably, a protective pad is fixedly connected to the bottom of the pressure plate, and the protective pad is circular.

[0014] Preferably, two connecting frames are fixedly connected between the two side frames, and the two connecting frames are arranged vertically.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The non-standard welding machine workpiece clamping mechanism shown in this embodiment includes: a fixed plate 1, a through groove 2 on the fixed plate 1, a movable plate 3 movably installed in the cavity of the through groove 2, two workbenches 17 fixedly installed on the top of the movable plate 3, and four side frames 6 fixedly connected to the bottom of the movable plate 3. Electric push rods 8 are fixedly installed on the top of the inner walls of the four side frames 6, and pressure plates 10 are fixedly connected to the bottom of the electric push rods 8. A side groove 12 is opened on one side of the outer wall of the fixed plate 1, and a servo motor 15 is fixedly installed on the other side of the outer wall of the fixed plate 1. A screw 14 is fixedly connected to the output end of the servo motor 15. A connecting plate 13 is fixedly connected to the bottom of the movable plate 3. One side of the connecting plate 13 extends into the cavity of the side groove 12. One end of the screw 14 passes through the outer wall of the fixed plate 1 and the connecting plate 13 and is threadedly connected to the connecting plate 13. The screw 14 is rotatably connected to the outer wall of the fixed plate 1.

[0029] Specifically, workpieces are first placed on the surfaces of the two worktables 17. Then, the electric push rod 8 is driven to push the pressure plate 10 downwards, using the two pressure plates 10 to press the workpieces firmly, allowing them to be stably welded. After one workpiece is welded, the servo motor 15 is driven to rotate the screw 14. The screw 14 moves the connecting plate 13, which in turn moves the movable plate 3. The movable plate 3 moves the welded workpiece to one side, while the unwelded workpieces are moved to the welding position to continue welding. During the welding operation on the non-standard welding machine, the operator can remove the welded workpieces and place new workpieces on the surface of the worktable 17. Repeating the above operation can improve the efficiency of welding workpieces.

[0030] In this embodiment, as Figures 2-4 As shown; two limiting rods 5 are fixedly connected to the inner wall of the through groove 2, and two limiting holes 4 are opened on the movable plate 3, with the two limiting rods 5 passing through the corresponding limiting holes 4 respectively.

[0031] Specifically, by utilizing the cooperation between the limiting rod 5 and the limiting hole 4, the horizontal movement trajectory of the movable plate 3 is limited, thereby improving the stability of the movable plate 3 during movement.

[0032] In this embodiment, as Figures 2-4 As shown; the inner diameter of the limiting hole 4 is set to be the same as the outer diameter of the limiting rod 5.

[0033] Specifically, this setting prevents the movable plate 3 from shaking or wobbling during movement.

[0034] In this embodiment, as Figures 1-2 As shown; a mounting bracket 16 is fixedly installed on the outer wall of the servo motor 15, and the mounting bracket 16 is fixedly connected to the outer wall of the mounting plate 1.

[0035] Specifically, the connection strength between the servo motor 15 and the outer wall of the fixing plate 1 is improved by using the fixing bracket 16, thereby further improving the stability of the servo motor 15 during subsequent operation.

[0036] In this embodiment, as Figure 5 As shown; a fixed seat 9 is sleeved and fixedly installed on the outer wall of the electric actuator 8, and the fixed seat 9 is fixedly connected to the top of the inner wall of the side frame 6.

[0037] Specifically, by setting the fixed base 9, the installation strength between the electric actuator 8 and the side frame 6 is improved, thereby improving the stability of the electric actuator 8 during subsequent operation.

[0038] In this embodiment, as Figure 5 As shown; a protective pad 11 is fixedly connected to the bottom of the pressure plate 10, and the protective pad 11 is circular.

[0039] Specifically, by using the protective pad 11, the problem of workpiece deformation and wear caused by the hard pressing between the pressure plate 10 and the workpiece can be avoided.

[0040] In this embodiment, as Figures 1-5 As shown; there are two connecting frames 7 fixedly connected between the two side frames 6, and the two connecting frames 7 are arranged vertically.

[0041] Specifically, the connection between the two side frames 6 is achieved by setting two connecting frames 7, thereby improving the clamping degree of the workpiece.

[0042] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
