Description
Technical Field
The invention relates to the field of mechanical equipment, in particular to smelting equipment, and more particularly relates to a vibrating table.
Background
The hydraulic vibration table is an important device of a modern slab casting machine and is used for guaranteeing the separation of a slab shell and a crystallizer copper plate. In order to ensure the quality of the slab, to avoid cracking, the vibrating table needs to move vertically. To ensure vertical movement of the oscillating table, it is necessary to limit the X-and Y-direction offsets during the movement of the oscillating table, which offset is referred to as the oscillating accuracy of the oscillating table. In order to ensure that the slab quality has very high requirements on the precision of the vibration of the vibrating table: the X-direction deviation is not more than 0.3mm, the Y-direction deviation is not more than 0.3mm, and the Z-direction deviation is 3% of the stroke.
The individual X-direction guide plates are worn, gaps are generated between the guide wheels and the guide plates, so that the vibrating table is not vertical when vibrating up and down, other guide devices are worn seriously, the vibration precision is out of tolerance, and the slab is subjected to angle cracking and longitudinal cracking defects. This phenomenon generally occurs after 6 months of use of the new vibration guide.
Disclosure of Invention
In order to solve the technical problems, the invention aims to provide an auxiliary positioning device for a vibrating table, which comprises a positioning plate, a positioning wheel and an auxiliary positioning device, wherein the auxiliary positioning device has the following structure: a support plate is arranged on the outer side of the vibrating table, a screw hole is formed in the support plate, and one end of a support screw rod is screwed into the screw hole and locked by a nut; the other end of the supporting screw is provided with a positioning block, and the distance between the positioning block and the positioning plate ensures that the positioning wheel is just abutted with the positioning plate; a pressure sensor is arranged between the positioning block and the supporting screw rod and is sleeved on the supporting screw rod; the pressure sensor is connected with a warning device of the control console.
The pressure sensor is annular and sleeved on the supporting screw rod, and the positioning block is connected to the supporting screw rod through threads; the two axial ends of the pressure sensor are respectively abutted with the positioning block and the convex ring of the supporting screw rod.
The auxiliary positioning device comprises a plurality of supporting screws and positioning blocks.
Each supporting screw is provided with a pressure sensor.
The invention has the advantages that: on one hand, the positioning block can ensure that when the positioning wheel is worn and the precision is reduced, the positioning block is used for compensation positioning; on the other hand, the pressure sensor is pressurized by utilizing the tiny activity brought by the bolt connection of the positioning block and the supporting screw, so that when the positioning block just starts to play a role in positioning, the pressure sensor is not started if the gap between the supporting screw and the positioning block is within a reasonable tolerance range, and the pressure sensor is started under the condition that the reasonable gap is exceeded.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The invention is specifically described below with reference to the accompanying drawings, as shown in fig. 1, a support plate 4 is arranged on the outer side of a vibrating table 1, a screw hole is arranged on the support plate 4, and one end 5 of a support screw rod is screwed into the screw hole and locked by a nut 8; the other end 7 of the supporting screw is provided with a positioning block 6, and the distance between the positioning block 6 and the positioning plate 2 ensures that the positioning wheel 3 is just abutted with the positioning plate 2; a pressure sensor 9 is arranged between the positioning block 6 and the supporting screw, and the pressure sensor 9 is sleeved on the supporting screw; the pressure sensor 9 is connected with a warning device of the control console. The pressure sensor transmits a pressure signal to the control console, and the PLC of the control console compares the pressure signal with a set value according to the pressure so as to judge whether to start the warning device or not, so that the guide wheel and the positioning block are replaced when the gap is overlarge.
The pressure sensor 9 is annular and sleeved on the supporting screw rod, and the positioning block is connected to the supporting screw rod through threads; the two axial ends of the pressure sensor 9 are respectively abutted against convex rings of the positioning block and the supporting screw, and the part of the structure is not shown in fig. 1, so that the structure is very simple and can be known by a person skilled in the art.
The pitch arrangement of the positioning block 6 and the supporting screw should ensure that the gap between the positioning block and the supporting screw is smaller than the preset gap between the positioning wheel 3 and the positioning plate 2. The specific setting method can adopt a general method, for example, the clearance between the positioning block 6 and the supporting screw is ensured by setting the tooth width, the tooth height, the clearance and the like which are matched with each other.
On one hand, the positioning block can ensure that the positioning block is used for compensation positioning when the positioning wheel is worn and the precision is reduced; on the other hand, the pressure sensor is pressurized by utilizing the tiny activity brought by the bolt connection of the positioning block and the supporting screw, so that when the positioning block just starts to play a role in positioning, the pressure sensor is not started if the gap between the supporting screw and the positioning block is within a reasonable tolerance range, and the pressure sensor is started under the condition that the reasonable gap is exceeded.
