[0013] The present invention is further provided that a mesh frame is fixedly provided on the through hole.

[0014] Three beneficial effects

[0015] Compared with the prior art, the present invention provides an automated electrical clamp, which has the following advantages:

[0016] 1. Through the clamping plate, the first clamping block and the second clamping block, and in conjunction with the top frame, electrical workpieces of different shapes can be clamped and fixed. By alternating the first and second clamping slots, cylindrical workpieces of different sizes can be clamped and fixed. The protruding strips on the clamping plate provide an anti-slip effect, which better clamps and fixes the workpiece.

[0017] 2. When clamping and fixing workpieces whose surfaces require protection using strong magnetic blocks and a fixing frame, rotate the fixing frame to face the top frame, and rotate the screw sleeve to adjust the distance between the strong magnetic blocks and the mesh plate. This facilitates adjusting the magnetic attraction effect on the workpiece, allowing for easy adjustment of the workpiece's position and angle for subsequent processing. Simultaneously, when the motor drives the screw to rotate, pushing the top frame and protective plate to clamp the workpiece, the protective plate elastically clamps the workpiece under the action of the buffer support, ensuring high safety and good protection for the workpiece.

[0018] Third, through the through holes and the collection box, when processing the workpiece, the debris can fall directly into the collection box through the through holes, and the debris on the table can also be easily swept to the through holes for cleaning. In addition, the wire mesh can prevent the workpiece from passing through the through holes, which is very practical. Attached Figure Description

The first clamping block 12 is provided with a first slot. A second clamping block 13 is fixedly provided on a set of the cross arms 10. Each second clamping block 13 is provided with a second slot. The first slot is at an acute angle and the second slot is at an obtuse angle. A support column 14 is fixedly provided on the turntable 7. A ball bearing 15 is rotatably provided on the support column 14. The ball bearing 15 is in contact with the bottom end face of the turntable 9. Each of the four sets of cross arms 10 is provided with a pin 16 that can slide up and down. A bottom ring 17 is fixedly provided on the pin 16. A spring 18 is sleeved on the pin 16. The bottom of the spring 18 is in contact with the bottom ring 17. A positioning seat 19 is fixedly provided on the turntable 7. The positioning seat 19 is provided with a positioning groove. The bottom of the pin 16 is inserted downward into the positioning groove.

[0031] Specifically, when processing the workpiece, the top frame 6 can be used to clamp and fix electrical workpieces of different shapes. The pin 16 can be pulled out from the positioning slot and the turntable 9 can be rotated. The clamping plate 11, the first clamping block 12 and the second clamping block 13 can be selected according to different workpieces. After selection, the pin 16 can be inserted into the positioning slot under the action of the spring 18 to lock the position. By alternating the first and second clamping slots, cylindrical workpieces of different sizes can be clamped and fixed. The convex strip on the clamping plate 11 provides an anti-slip effect and better clamps and fixes the workpiece.

[0032] Please see Figure 1 , Figure 3 and Figure 6 An implementation method for fixing magnetically attachable workpieces is as follows: A fixing frame 20 is fixedly mounted on a set of cross arms 10. A sliding rod 21 is fixedly mounted on the fixing frame 20. A strong magnetic block 22 is slidably sleeved on the sliding rod 21. A threaded rod 23 is fixedly mounted on the strong magnetic block 22. An adjusting frame 24 is fixedly mounted on the fixing frame 20. A screw sleeve 25 is rotatably mounted on the adjusting frame 24. The threaded rod 23 is threadedly connected to the screw sleeve 25. A handwheel is fixedly mounted on the screw sleeve 25. A square hole is provided on the fixing frame 20, corresponding to the strong magnetic block 22. A mesh plate is fixedly mounted in the square hole. A fixing block 26 is fixedly mounted on the top frame 6. A buffer support 27 is fixedly mounted on the fixing block 26. A protective plate 28 is fixedly mounted at the end of the buffer support 27. A guide rod 29 is fixedly mounted on the protective plate 28. The end of the guide rod 29 passes through the fixing block 26 and can slide left and right.

[0033] Specifically, when clamping and fixing workpieces whose surfaces require protection, the fixing frame 20 is rotated to be opposite to the top frame 6, and the screw sleeve 25 is rotated to adjust the distance between the strong magnetic block 22 and the mesh plate, which facilitates the adjustment of the strong magnetic attraction effect on the workpiece. This allows for easy adjustment of the workpiece's position and angle, facilitating subsequent processing. At the same time, when the motor 4 drives the screw 3 to rotate, pushing the top frame 6 and the protective plate 28 to clamp the workpiece, the protective plate 28 elastically clamps the workpiece under the action of the buffer support 27, ensuring high safety and good protection for the workpiece.

[0034] Please see Figure 1 and Figure 7 The implementation method of cleaning the platform is as follows: The platform 1 is provided with a through hole 30, the through hole 30 is provided with a ring strip 31, the platform 1 is provided with a base frame 32, the base frame 32 is provided with a collection box 33, the collection box 33 is located below the through hole 30, and a mesh frame 34 is fixedly provided on the through hole 30.

[0035] Specifically, when processing the workpiece, debris can fall directly into the collection box 33 through the through hole 30. The debris on the table 1 can also be easily swept to the through hole 30 for cleaning. Furthermore, the mesh frame 34 can prevent the workpiece from passing through the through hole 30, making it highly practical.

[0036] In summary, when using the overall equipment:

[0037] When processing the workpiece, the top frame 6 can be used to clamp and fix electrical workpieces of different shapes. The pin 16 can be pulled out from the positioning groove and the turntable 9 can be rotated. The clamping plate 11, the first clamping block 12 and the second clamping block 13 can be selected according to different workpieces. After selection, the pin 16 can be inserted into the positioning groove under the action of the spring 18 to lock the position. By alternating the first and second clamping slots, cylindrical workpieces of different sizes can be clamped and fixed. The convex strip on the clamping plate 11 provides an anti-slip effect and better clamps and fixes the workpiece.

[0038] When clamping and fixing workpieces whose surfaces require protection, the fixing frame 20 is rotated to be opposite to the top frame 6, and the screw sleeve 25 is rotated to adjust the distance between the strong magnetic block 22 and the mesh plate, which makes it easy to adjust the adsorption effect of the strong magnet on the workpiece. Thus, the position and angle of the workpiece can be easily adjusted, which is convenient for subsequent processing. At the same time, when the motor 4 drives the screw 3 to rotate and pushes the top frame 6 and the protective plate 28 to clamp the workpiece, the protective plate 28 elastically clamps the workpiece under the action of the buffer support 27, which has high safety and good protection effect on the workpiece.

[0039] When processing the workpiece, debris can fall directly into the collection box 33 through the through hole 30. The debris on the table 1 can also be easily swept to the through hole 30 for cleaning. Furthermore, the mesh frame 34 can prevent the workpiece from passing through the through hole 30, making it highly practical.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
