Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 and Figure 3 in, Figure 1 A schematic diagram of a preferred embodiment of the workpiece clamping device provided by this utility model; Figure 2 A schematic diagram of a preferred embodiment of the workpiece positioning system provided by this utility model; Figure 3 for Figure 1 A schematic diagram of the pressure plate and anti-slip pad of the workpiece clamping device is shown. The workpiece clamping device includes: multiple vertically arranged electrically controlled telescopic rods 1 and multiple extension clamping mechanisms;

[0022] The bottom ends of multiple electrically controlled telescopic rods 1 are horizontally fixedly connected to a main pressing plate 2, and multiple extension pressing mechanisms are all set on the outer surface of the main pressing plate 2;

[0023] The structures of the multiple extension clamping mechanisms are all the same. One of the extension clamping mechanisms includes two slide grooves opened on the side surface of the main clamping plate 2 along the radial direction. The slide rods 3 are laterally slidably connected inside the two slide grooves. The outer ends of the two slide rods 3 are laterally fixedly connected to the connecting pieces 4. The side surface of the main clamping plate 2 and located between the two slide rods 3 are laterally opened with mounting grooves parallel to the slide rods 3. The inside of the mounting groove is laterally fixedly connected to a threaded sleeve 5. The inside of the threaded sleeve 5 is laterally threaded with a threaded post 7 whose outer end rotatably passes through the connecting piece 4 and extends outward. The bottom end of the outer surface of the connecting piece 4 is laterally fixedly connected to a cross plate 9. An adjustable pressure plate 13 is provided below the cross plate 9.

[0024] A column 10 is vertically fixedly connected to the upper surface of the horizontal plate 9. A threaded hole is opened at the top of the column 10, which extends to the lower surface of the horizontal plate 9. A lead screw 11 is vertically threaded inside the threaded hole, and the pressure plate 13 is rotatably connected to the bottom end of the lead screw 11.

[0025] Multiple extended clamping mechanisms are evenly spaced along the circumference of the main clamping plate 2.

[0026] The clamping structure of the device includes a main clamping plate 2, on the outer surface of which multiple extended clamping mechanisms are provided. The outer ends of the multiple extended clamping mechanisms can move along a radial direction of the main clamping plate 2, and the pressure plates 13 of the multiple extended clamping mechanisms can also freely adjust the horizontal position of their bottom ends. When the device clamps the workpiece, while the main clamping plate 2 clamps the highest surface of the workpiece, the pressure plates 13 of the multiple extended clamping mechanisms can respectively clamp multiple lower surfaces of the workpiece, increasing the contact area, which can ensure that the device can clamp the workpiece more stably.

[0027] When it is necessary to adjust the outward extension length of the pressure dividing plate 13, rotate the threaded column 7. During the rotation, the threaded column 7 can move along the length direction of the threaded sleeve 5 due to the action of the threaded sleeve 5. In this process, the connecting piece 4 is driven to move laterally, thereby synchronously driving the structure connected to the outer end of the connecting piece 4 to move synchronously. When it is necessary to adjust the height of the pressure dividing plate 13, rotate the lead screw 11. The lead screw 11 moves vertically under the action of the threaded hole, thereby driving the pressure dividing plate 13 to move vertically.

[0028] The outer end of the threaded column 7 is fixedly connected to a first torsion block 8, and the top end of the lead screw 11 is fixedly connected to a second torsion block 12.

[0029] The first torsion block 8 and the second torsion block 12 can drive the threaded column 7 and the lead screw 11 to rotate respectively, making it convenient for people to adjust the extension and pressing mechanism.

[0030] Reinforcing ribs 6 are fixedly connected to both sides between the connecting piece 4 and the horizontal piece 9.

[0031] The reinforcing rib 6 can enhance the connection stability between the connecting piece 4 and the cross piece 9, thereby improving the overall structural strength of the structure.

[0032] Anti-slip pads 22 are fixedly connected to the lower surfaces of the main pressure plate 2 and multiple pressure plates 13.

[0033] The anti-slip pad 22 can provide an anti-slip effect and improve the stability of the device after clamping the workpiece.

[0034] A workpiece positioning system includes the aforementioned workpiece clamping device, comprising a placement plate 14. Side transverse grooves 15 and end transverse grooves 16 are respectively formed along the length and width directions on both sides and both ends of the upper surface of the placement plate 14. Electric slide rails 17 are fixedly connected to the interior of each of the two side transverse grooves 15 and the two end transverse grooves 16 along their length direction. Positioning clamps 18 are fixedly connected to the sliding surfaces of the multiple electric slide rails 17. Supporting rods 19 are vertically fixedly connected to multiple corners of the upper surface of the placement plate 14. A top plate 20 is horizontally fixedly connected to the upper surface of the multiple supporting rods 19. Multiple connecting holes 21, each adapted to a multiple electrically controlled telescopic rod 1, are vertically opened through the middle of the upper surface of the top plate 20. The multiple electrically controlled telescopic rods 1 are respectively fixedly connected to the interior of the multiple connecting holes 21.

[0035] After the workpiece is placed in the middle of the upper surface of the placement plate 14, multiple electric slide rails 17 will start to run, and multiple sliding parts will move closer to the workpiece until the workpiece is completely fixed and clamped by the positioning clamps 18 at the top of the multiple sliding parts. The workpiece can be positioned by this structure.

[0036] The working principle of the workpiece clamping device and workpiece positioning system provided by this utility model is as follows:

[0037] When it is necessary to adjust the outward extension length of the pressure plate 13, rotate the threaded column 7. During the rotation, the threaded column 7 can move along the length direction of the threaded sleeve 5 due to the action of the threaded sleeve 5. In this process, the connecting piece 4 is driven to move laterally, thereby synchronously driving the structure connected to the outer end of the connecting piece 4 to move synchronously. When it is necessary to adjust the height of the pressure plate 13, rotate the lead screw 11. The lead screw 11 moves vertically under the action of the threaded hole, thereby driving the pressure plate 13 to move vertically. This allows the device to press the highest surface of the workpiece with the main pressing plate 2, while the pressure plates 13 of the multiple extended pressing mechanisms can press the multiple lower surfaces of the workpiece respectively, increasing the contact area and ensuring that the device can press the workpiece more stably.

[0038] Compared with related technologies, the workpiece clamping device and workpiece positioning system provided by this utility model have the following beneficial effects:

[0039] This utility model provides a workpiece clamping device and a workpiece positioning system. By setting multiple extended clamping mechanisms, the clamping structure of the device includes a main clamping plate 2, and multiple extended clamping mechanisms are set on its outer surface. The outer ends of the multiple extended clamping mechanisms can move along a radial direction of the main clamping plate 2, and the pressure plates 13 of the multiple extended clamping mechanisms can also freely adjust the horizontal position of their bottom ends. When the device clamps the workpiece, while the main clamping plate 2 clamps the highest surface of the workpiece, the pressure plates 13 of the multiple extended clamping mechanisms can respectively clamp multiple lower surfaces of the workpiece, increasing the contact area, which can ensure that the device can clamp the workpiece more stably.
