Description

Technical Field

[0001] This utility model belongs to the field of metal clamping technology, and relates to a clamping device with an adjustable clamping structure. Background Technology

[0002] The main drawbacks of existing metal clamping devices in terms of stable clamping are unstable clamping force, low clamping accuracy, and potential damage to the workpiece during clamping. These drawbacks arise from various causes, including design flaws in the clamping device and insufficient control precision of the clamping mechanism. For example, if the jaw design of the clamping device fails to adequately consider the shape and size of the workpiece, it may lead to uneven distribution of clamping force; insufficient elastic modulus of the material or severe wear can cause a decrease in clamping force; and insufficient precision of the control system may cause fluctuations in clamping force.

[0003] Conventional solutions include improving the design of the clamping device and increasing the precision of the control system. However, these methods also have drawbacks. Improving the design may require significant R&D investment and time, and may not completely solve all problems. Increasing the precision of the control system requires a more complex control system and possible hardware upgrades, which also increases costs and operational complexity. Therefore, there is an urgent need for a clamping device with an adjustable clamping structure to address these issues. Summary of the Invention

The lower end of the electric cylinder 190 is provided with a set of connecting plates 210 for driving the three sets of movable columns 220 to move up and down synchronously. The connecting plates 210 are fixed to the telescopic end of the electric cylinder 190 by bolts. The electric cylinder 190 can be used to drive the three sets of movable columns 220 to move up and down synchronously, and the three sets of movable arms 230 and the three sets of clamping arms 240 can be retracted synchronously, and the lower inner side of the three sets of clamping arms 240 can be clamped with the metal parts.

[0027] The top view of the connecting plate 210 is an equilateral triangle structure, and each corner of the connecting plate 210 is provided with a set of movable columns 220 for pulling a set of movable arms 230. All three sets of movable columns 220 penetrate the lower end of the housing, and a set of rubber bushings for sealing and fitting is provided at the penetration point between the movable column 220 and the lower end of the housing.

[0028] A set of movable arms 230 for driving the clamping arm 240 to move is provided on the outer side of the lower end of the movable column 220. A set of rotating shafts is provided at the connection between the movable arm 230 and the movable column 220. The movable column 220 and the movable arm 230 are movably connected.

[0030] Each clamping arm 240 has an anti-slip pad 250 on its inner side to improve the clamping anti-slip effect. The upper end of the limiting plate 200 is connected and fixed to the lower end of the electric cylinder 140 by bolts. The lower end of the limiting plate 200 has an inner shell 180.

[0031] Please see Figures 1-4 As the first embodiment of this utility model: When the operator needs to position and clamp a metal workpiece, the metal workpiece is first placed on the upper end of the operating table 160. Then, the operator adjusts the lead screw to position the metal workpiece as needed, and the lead screw drives the moving lead seat 170 to move left and right, so that the center position of the three sets of clamping arms 240 is located above the center position of the metal workpiece. Then, the operator adjusts the electric cylinder 140, which drives the electric cylinder 290 and the connecting plate 210 to move downward, so that the three sets of clamping arms 240 are located at the upper end of the center position of the metal workpiece. On the outside of the metal part, the operator then activates the electric cylinder 190, which moves the connecting plate 210 upward. Since the connecting plate 210 and the telescopic end of the electric cylinder 190 are fixed by bolts, the electric cylinder 190 can be used to synchronously move the three sets of movable columns 220 up and down, and synchronously retract the three sets of movable arms 230 and the three sets of clamping arms 240.

When the connecting plate 210 moves upward, it can drive the three sets of movable columns 220 and the movable arm 230 to stretch upward, and cause the movable arm 230 to change angle. Then, the movable arm 230 drives the clamping arm 240 to retract inward, thereby clamping the outer side of the metal part at three points. Each set of clamping arms 240 is provided with a set of anti-slip pads 250 on the inner side to improve the clamping anti-slip effect. The anti-slip pads 250 can protect the outer side of the metal workpiece while increasing the clamping friction, thereby preventing the metal part from moving in its positioning position.
