Problems solved by technology

The vibration transmission of the existing three-dimensional vibration platform is mainly carried out by plane contact and linear contact. The disadvantages are that the sand box and the table need a large clamping force, resulting in serious wear of the table; Motors, clamping devices, etc. are easily damaged. Third, three pairs of motors must be installed to achieve three-dimensional vibration.

Abstract

The invention discloses a table top of a vibration platform, and a sand box can be mounted on the table top movably. The table top includes a bedplate (7) driven to vibrate by a vibration mechanism. The invention is characterized in that the bedplate (7) is provided with three supporting pillars (2). One ends of the supporting pillars (2) are positioned with the bedplate (7) through spigots, and are connected to the bedplate (7) by bolt pairs. The other ends of the supporting pillars (2) are equipped with connecting seats (3) for mounting the sand box. And the contact surfaces between the connecting seats (3) and the sand box are convex conical surfaces. With simple structure and low noise, the invention can realize automatic position of the sand box without clamping, and can effectively transmit a vibration source and has a great excitation force. Meanwhile, the use of only one pair of motors can generate three-dimensional vibration.

Description

technical field [0001] The invention relates to a vibrating platform, in particular to a table top of the vibrating platform. Background technique [0002] The vibrating platform is also called the vibrating platform. It is divided into three vibration modes: up and down vibration, spiral vibration and three-dimensional vibration. It is mainly used for compacting materials and reducing air and gaps in materials. [0003] The three-dimensional vibration platform is mainly used for the vibration of resin sand molding and lost foam molding. It consists of four parts: base, table top, vibration mechanism and shock absorption mechanism. The vibrating motor drives the table to vibrate to fully compact the sand and fill the mold. The vibration transmission of the existing three-dimensional vibration platform is mainly carried out by plane contact and linear contact. The disadvantages are that the sand box and the table need a large clamping force, resulting in serious wear of the ...
