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
The present invention relates to a kind of shaking platform, specifically a kind of table top of shaking platform.
Background technology
Shaking platform is plain bumper again, is divided into up-down vibration, spiral vibrating and three kinds of mode of vibrations of three-dimensional vibrating, is mainly used in the ram-jolt of material, reduces air and slit in the material, the general and supporting use of feed bin.
The three-dimensional vibrating platform is mainly used in phenolic sand molding jolt ramming and the jolt ramming of disappearance model type, and it is by base, table top, vibrating mechanism, and damping four parts are formed.Driving table vibration through vibrating motor makes the abundant consolidation of sand and is full of casting mold.It mainly is to lean on plane contact to carry out with linear the contact that the vibration of existing three-dimensional vibrating platform is transmitted; Its shortcoming one is that sandbox and table top need bigger clamping force; Cause the table top serious wear; The 2nd, under big exciting force, its motor, clamping device etc. damage easily, and the 3rd, the realization three-dimensional vibrating must be installed three pairs of motors.
Summary of the invention
The table top that the purpose of this invention is to provide a kind of shaking platform of movable installation sandbox.
The present invention adopts following technical scheme to realize its goal of the invention; A kind of table top of shaking platform, it comprises the platen that is driven vibration by vibrating mechanism, is laid with three support columns on the platen; Support column one end and platen are located by seam; Be connected on the platen with the bolt pair, the other end of support column is provided with the Connection Block that is used to install sandbox, and the contact-making surface of Connection Block and sandbox is the convex cone face.
The present invention is for reducing noise, and described Connection Block is processed by hard rubber or ptfe plastic.
Because adopt technique scheme, the present invention has realized goal of the invention preferably, it is simple in structure; Noise is little, can locate automatically at the situation drag box that does not have clamping, effectively the transmitting vibrations source; Exciting force is big, simultaneously, only just can produce three-dimensional vibrating with a pair of motor.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Can know by Fig. 1; A kind of table top of shaking platform, it comprises the platen 7 that is driven vibration by vibrating mechanism, is laid with three support columns 2 on the platen 7; Support column 2 one ends and platen 7 are located by seam; Be connected on the platen 7 with the bolt pair, the other end of support column 2 is provided with the Connection Block 3 that is used to install sandbox, and Connection Block 3 is the convex cone face with the contact-making surface of sandbox.
The platen 7 that the present invention is equipped with vibrating mechanism is installed on the base 1 through 8～12 (present embodiment is 8) air bags 6, through to filling, put compressed air in the air bag 6, can control the ascending, descending of platen 7.Sandbox bottom is welded with the bowl seat 4 corresponding with support column 2, and the contact-making surface of bowl seat 4 and Connection Block 3 is the concave cone face,
The present invention is for reducing noise, and described Connection Block 3 is processed (present embodiment is a hard rubber) by hard rubber or ptfe plastic.
When the present invention uses, sandbox is installed on the Connection Block 3 of support column 2, the center of gravity vertical line of sandbox overlaps with the center of the supporting surface that three support columns 2 are formed.During work, platen 7 drives up-down vibration by motor 5, and its exciting force passes to the sandbox on the bowl seat 4 through support column 2, Connection Block 3, with the material jolt ramming in the sandbox.Because Connection Block 3 and bowl 4 for the conical surface contacts, during the sandbox up-down vibration, produce component in the horizontal direction, therefore, only just can realize the three-dimensional vibrating of sandbox with a pair of motor.
Claims (2)
1. the table top of a shaking platform; It comprises the platen (7) that is driven vibration by vibrating mechanism; It is characterized in that being laid with on the platen (7) three support columns (2), support column (2) one ends and platen (7) are connected on the platen (7) with the bolt pair by the seam location; The other end of support column (2) is provided with the Connection Block (3) that is used to install sandbox, and Connection Block (3) is the convex cone face with the contact-making surface of sandbox.
2. the table top of shaking platform according to claim 1 is characterized in that described Connection Block (3) processed by hard rubber or ptfe plastic.
