[0022] Please refer to Figures 1 to 3The multifunctional clamp shown in an embodiment of the present application comprises a fixing member, the fixing member comprises a fixing base 10 and a clamp platform 20 connected to the fixing base 10, the clamp platform 20 has at least three mounting positions for mounting clamping mechanisms, the mounting positions are used for mounting different types of clamping mechanisms, and at least one of the clamping mechanisms is an insert clamping mechanism 30, the insert clamping mechanism 30 comprises a telescopic structure arranged in the clamp platform 20, a clamping structure connected to the telescopic structure, and a pair of clamping teeth 32 arranged on the clamping structure, and a clamping arc surface 33 is formed on the clamping teeth 32. By arranging the clamping arc surface 33, workpieces with a clamped surface larger than the clamping arc surface 33 can be clamped by the two ends, and workpieces with a clamped surface smaller than the clamping arc surface 33 can be clamped in the clamping arc surface 33. The clamping arc surface 33 can provide more effective clamping surfaces in the clamping plane, circular arc surface or other planes, thereby improving the clamping effect. In addition, in order to improve the friction of the clamping arc surface 33, a tooth surface anti-skid structure is arranged on the clamping arc surface 33.
[0023] The fixing base 10 is provided with a connecting part 11 for connecting with different types of connecting flanges 12. By connecting with different connecting flanges 12, the multifunctional clamp can be connected with different mechanical hands or other driving devices, so that the multifunctional clamp can be used in different processing scenes, improving its practicability.
[0024] It should be noted that the other clamping mechanisms except the insert clamping mechanism 30 can be pneumatic clamping mechanisms, hydraulic clamping mechanisms, mechanical clamping mechanisms or other mechanical clamping mechanisms, which can be set as needed and are not limited here.
[0025] In an embodiment, the cross-sectional area of the clamp platform 20 decreases from one end close to the fixing base 10 to the other end away from the fixing base 10. During the processing, the front end of the clamp platform 20 needs to be close to the workpiece, even to extend into the workpiece. Therefore, by setting the front end of the clamp platform 20 to be smaller than the rear end, the stability of the connection between the rear end of the clamp platform 20 and the fixing base 10 can be ensured, and the volume of the front end of the clamp platform 20 can be reduced to avoid collision between the clamping mechanism and the workpiece and interference.
[0026] In an embodiment, the clamp platform 20 is a right-angled trapezoidal body, and the right-angled trapezoidal body is provided with three mounting positions, including a front end mounting position 22 in contact with the inclined surface and two side mounting positions 21. In this way, when the three clamping mechanisms are located on the three mounting positions, the center of gravity of the overall structure can be located on the clamp platform 20, reducing the difficulty of operating the clamp platform 20. Of course, in other embodiments, the mounting positions can be four or five, and the clamp platform 20 can be other shapes, which can be set as needed and are not limited here.
[0027] In addition, the inclined surface of the right-angled trapezoidal body is provided as a detachable connecting plate, so that the mechanism in the fixture platform 20 can be easily overhauled by removing the connecting plate.
[0028] In an embodiment, at least one of the two side mounting positions 21 is used to mount the insert clamping mechanism 30. During the use of the multifunctional fixture, the front end mounting position 22 is generally provided to clamp a workpiece with a large volume, while the insert is small, and the insert clamping mechanism 30 is arranged on the two side mounting positions 21, so as to effectively avoid interference during clamping. The number of insert clamping mechanisms 30 can be set as required, which is not specifically limited here.
[0029] In an embodiment, the side mounting position 21 is provided with a waist-shaped hole 211 and a fixing hole formed on the inner circumferential side of the waist-shaped hole 211, and the extension structure and the clamping structure are arranged on the inner and outer sides of the waist-shaped hole 211, respectively. By arranging the extension structure in the fixture platform 20 and the clamping structure outside the fixture platform 20, the movable hole for the extension structure to move on the side mounting position 21 can be reduced, thereby improving the stability of the structure of the fixture platform 20.
[0030] In an embodiment, the extension structure is a telescopic cylinder 34, and the clamping structure is a clamping cylinder 31, and the clamping cylinder 31 is fixed on the output shaft of the telescopic cylinder 34. Since the volume of the insert is limited, the cooperation of the telescopic cylinder 34 and the clamping cylinder 31 can not only realize clamping movement, but also reduce the volume of the insert clamping mechanism 30.
[0031] In an embodiment, the multifunctional fixture further comprises a fixing plate for supporting the output shaft of the telescopic cylinder 34 and a side sealing plate for sealing the waist-shaped hole 211, and the fixing plate and the side sealing plate are selectively fixed on the fixing hole. The waist-shaped hole 211 is arranged on both side mounting positions 21 of the fixture platform 20, and in actual use, the insert clamping mechanism 30 on both sides can be flexibly disassembled to adapt to different working conditions. When the insert clamping mechanism 30 is installed, the fixing plate is installed at the waist-shaped hole 211, and the fixing plate is formed with a through hole matched with the size of the output shaft of the telescopic cylinder 34, so as to support the telescopic cylinder 34 and prevent shaking. When the insert clamping mechanism 30 is not installed, the side sealing plate is installed at the waist-shaped hole 211 to prevent foreign matter from entering the fixture platform 20.
[0032] The present application provides at least three mounting positions on the fixture platform to mount different types of mechanisms, thereby realizing the connection of multiple clamping mechanisms through one fixing seat, improving the diversity of the clamping mechanisms on the fixing seat, and providing at least one insert clamping mechanism with a clamping arc surface. The clamping arc surface can provide a moderate clamping surface for inserts of different shapes and sizes, thereby improving the adaptability of the fixture.
[0033] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered as the scope of the description.
[0034] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent scope. It should be pointed out that for ordinary skilled person in the art, under the premise of not departing from the utility model concept, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
