Detailed Description

An embodiment of a pneumatic clamping vibration die table is shown in figures 1-8, wherein a main body of a vibration platform 1 is a rectangular platform structure formed by welding section steel, a lower edge of a lower structure of the vibration platform is positioned on a plane and is an upper surface, an upper edge of an upper structure of the vibration platform is positioned on a plane and is an upper surface, a supporting block 2 is fixedly and convexly arranged on the lower surface of the vibration platform 1, namely the supporting block protrudes below the lower surface of the vibration platform 1, an air spring 3 is arranged between the supporting block 2 and a ground foundation, the air spring 3 is a commercially available part and belongs to a mature product, the upper part of the air spring 3 is fixedly connected with the supporting block 2, and the lower part of the air spring 3 is fixed with the ground foundation. Still fixedly on the lower surface of vibration platform 1 is provided with vibrating motor 4, and vibrating motor also is the market purchase piece, and vibrating motor 4 vibration can drive the vibration platform vibration.

Clamping arms 5 are hinged to two sides of the vibration platform 1, the clamping arms 5 on the two sides of the vibration platform are in one-to-one correspondence, namely the two corresponding clamping arms 5 are positioned on a straight line parallel to the end edge of the vibration platform. The vibration platform 1 is square, two parallel sides of the vibration platform are sides, the other two sides are ends, no special requirement is required before definition, and the definition is relatively determined later. Each clamp arm 5 is articulated with shaking platform 1 at the middle part, all have the kink 6 of bending to its clamp arm that corresponds at the upper end of each clamp arm 5, kink 6 is the level and extends, it is equipped with clamping wheel 7 to rotate on the end of kink 6, clamping wheel 7 is used for compressing tightly mould platform 10 on shaking platform, 5 kink 6 relative buckling of a pair of clamp arm, also be exactly to buckling toward different directions, and buckle with the mode that the distance diminishes, all stretch to shaking platform's inside promptly, only so can press from both sides the mould platform of placing on shaking platform, also compress tightly on the border of mould platform promptly. A clamping cylinder 8 is arranged between the lower end of the clamping arm 5 and the vibration platform 1, a cylinder body and a piston rod of the clamping cylinder 8 are respectively hinged with the lower end of the clamping arm and the supporting block 2 on the vibration platform, and the clamping cylinder 8 is hinged on the side surface of the supporting block 2. After the piston rod of the clamping cylinder 8 is extended, the lower end of the clamping arm 5 is pushed outwards away from the vibration platform 1, so that the upper end of the clamping arm 5 rotates towards the inner side of the vibration platform 1, and thus the clamping wheel on the clamping arm descends and presses the edge of the die table.

Two sides of the upper surface of the vibration platform 1 are respectively provided with a supporting surface 9 in a protruding way, and the two supporting surfaces 9 are parallel and parallel to the side edge of the vibration platform 1. The mould table 10 is pressed on two support surfaces 9, which are in direct contact with the mould table 10.
