Movable position platform for large wind power casting

Abstract

The invention provides a movable position platform for a large wind power casting. The movable position platform for the large wind power casting has the scheme that the movable position platform comprises a micro-vibration bracket, wherein a bidirectional worm is arranged on the micro-vibration bracket, and is provided with a forward rotation direction section and a reverse rotation direction section; each of the forward rotation direction section and the reverse rotation direction section is connected with a respectively matched turbine; a centering clamping mechanism is arranged on each turbine, and comprises a bidirectional screw rod, two screw nut blocks and a connecting element; the bidirectional screw rod is arranged on the turbine through the connecting element, so that the bidirectional screw rod can move along with the turbine but cannot rotate along with the turbine; the two screw nut blocks are arranged on screws with opposite screwing directions of a bidirectional screw nut; and the screw nut blocks are fixedly connected with movable clamping jaws. The effect that a large casting moves along with the micro-vibration bracket is achieved; the positioning requirement is met; and the damage to a mold die plate or the damage to the large casting due to movement of the large casting during micro-vibration of the micro-vibration bracket can be avoided.

Description

technical field [0001] The invention relates to the field of large casting equipment, in particular to a movable position platform for large wind power castings. Background technique [0002] In order to ensure the compactness of the molding sand, currently large-scale wind power castings require micro-vibration during molding. Usually the microseismic table is flush with the horizontal plane of the modeling pit. For large-scale wind power castings, the mold size is relatively large, and it needs to be supported by the microseismic bracket and placed on the microseismic table. It is easy to bump and damage the mold plate when it vibrates left and right; moreover, due to the large size and heavy weight of the mold, it is easy to be placed sideways when placed, and it is difficult to move and locate after being placed on the microseismic support and microseismic table. As a result, normal production is delayed and production efficiency is greatly reduced; at the same time, mo...

Problems solved by technology

[0005] On the one hand, in order to solve the above-mentioned technical problem that the large-scale casting mold is not easy to locate on the micro-seismic support and the micro-seismic table, the technical solution adopted is: a movable position platform for large-scale wind power castings, including the micro-seismic support and mobile Claws, the moving claws are located on the upper part of the microseismic support and can move forward, backward, left, and right on the microseismic support to clamp and position large castings; the microseismic support is equipped with a two-way worm, and the two-way worm has a forward rotation section and a reverse rotation section. The rotation section is connected with a worm gear adapted to it on the forward rotation section and the reverse rotation section, and a centering clamping mechanism is installed on the turbine, and the forward rotation section and the reverse rotation section can be rotated by turning the worm. The two turbines on the section drive two centering clamping mechanisms mounted on the turbines to move towards each other; the centering clamping mechanism includes a two-way screw, a nut block and a connecting piece, and the two ends of the two-way screw pass through the connecting piece Being installed on the turbine can make the two-way screw move with the turbine but not rotate with the turbine. There are two nut blocks and these two nut blocks are respectively installed on the screws of the opposite direction of rotation of the two-way nut. Each nut block corresponds to a moving card. jaw and the mobile jaw is firmly connected to the nut block
