Description

Technical Field

[0001] The invention relates to the technical field of metal component processing, and in particular to a surface treatment device for processing bridge metal components. Background Art

[0002] Bridges generally refer to structures built on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. During the construction of steel tube concrete tied arch bridges, they are usually processed into several steel structure segments in a steel structure prefabrication plant, and then the steel structures are connected and fixed by metal components. When processing metal components, in order to facilitate the subsequent painting operation, it is necessary to grind their surfaces to ensure the smoothness of the metal component surfaces. When the existing metal component surface treatment devices are grinding metal components, in order to achieve a comprehensive grinding effect on the metal components, it is necessary to manually adjust the position or increase the position of the metal components by adding a driving mechanism. Manual adjustment is more troublesome, and adding an external driving mechanism for adjustment will greatly increase the production cost of the device. Therefore, in view of the above problems, a surface treatment device for bridge metal component processing is designed to better meet the grinding needs of metal components. Summary of the invention

[0003] The object of the present invention is to provide a surface treatment device for processing bridge metal components to solve the problems raised in the above-mentioned background technology.

When the threaded rod, the disc and the convex shaft are driven to rotate by the first motor, the grinding mechanism moves laterally, and the sliding action between the convex shaft and the slide groove rod is coordinated to make the connecting frame, the electromagnet and the workpiece on the electromagnet move back and forth synchronously and orderly.

[0005] Preferably, four supporting legs are fixed to the lower end surface of the workbench, and a fixing plate is symmetrically fixed to the upper end surface of the workbench, and a cleaning mechanism is installed on the fixing plate. Through the above structure, stable support of the device can be guaranteed.

[0006] Preferably, fixed rods are symmetrically fixed between the fixed plates, and the fixed rods are slidably connected to the ear plates, and the fixed rods are slidably connected to the connecting frame. When the electromagnet moves, the stability of the movement of the electromagnet can be ensured by the sliding guiding effect between the fixed rods and the ear plates.

Combined with the sliding guiding effect between the movable block and the guide rod, the stability of the movement of the movable block can be ensured.

[0008] Preferably, positioning blocks are fixed symmetrically on the guide rod, and the positioning blocks contact the movable block to achieve positioning. When the movable block moves, the positioning blocks can limit the extreme position of the movable block's movement, thereby ensuring the normal operation of the device.

[0010] Preferably, the rotation diameter of the cam shaft is larger than the width of the electromagnet, and the width of the electromagnet is smaller than half the distance between the front and rear fixed plates. By limiting the rotation diameter of the cam shaft, a basic guarantee can be provided for comprehensive grinding of the workpiece, and by limiting the width of the electromagnet, it can be avoided that the electromagnet collides with the fixed plate when moving, thereby ensuring the normal operation of the device.

A one-way air outlet valve is also installed on the elastic airbag, and the one-way air outlet valve is interconnected with the hollow plate through a conduit, and the hollow plate is fixed on the fixed frame front and back. Through the action of the one-way air inlet valve and the one-way air outlet valve, a basic guarantee can be provided for the one-way exhaust of the elastic airbag, thereby ensuring the normal operation of the device.

[0013] Preferably, nozzles are evenly fixed on the lower end surfaces of the hollow plates, and the distance between the two hollow plates is greater than the diameter of the grinding head. The high-speed airflow ejected by the nozzles can blow away the debris generated by grinding, and by limiting the distance between the two hollow plates, the collision between the hollow plates and the grinding head can be avoided, thereby avoiding damage to the device.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the surface treatment device for processing bridge metal components adopts a screw drive mechanism, which can make the grinding mechanism move laterally, and cooperate with the linked swing mechanism, when the grinding mechanism moves laterally, the electromagnet and the workpiece can move back and forth in an orderly manner, so that the comprehensive grinding of the workpiece can be achieved, and no external drive mechanism is required to move the workpiece, making the entire device more compact and effectively reducing the production cost of the device. In combination with the linked cleaning mechanism, the debris on the surface of the workpiece after grinding can be cleaned to ensure the cleanliness of the workpiece. The specific contents are as follows: 1.
