Description

Technical Field

[0001] The utility model relates to the technical field of galvanized steel plates, in particular to a device for grinding galvanized steel plates after welding. Background Art

[0002] Galvanized steel sheet is a steel sheet with a layer of zinc on the surface. This kind of zinc-coated steel sheet is called galvanized sheet. Galvanized steel sheet is rust-proof, corrosion-resistant, beautiful and durable. It is a common type of steel sheet to prevent the surface of the steel sheet from corrosion and extend its service life. During the processing of galvanized steel sheet, welding is performed to connect two or more galvanized steel sheet parts. After welding, grinding by grinding device can remove defects on the weld surface, such as welding defects, oxide scale, charring, burrs, etc., making the surface smoother and flatter, and improving the appearance quality.

[0003] The existing Chinese patent with announcement number CN213917458U discloses a groove grinding device for steel plate welding, including a body and a guide rail, a transmission mechanism and a battery are arranged on the front side of the body, a first slide groove is opened on the body, a lifting mechanism is arranged inside the first slide groove, an electric screw is arranged on the lifting mechanism, a sliding seat is screwed on the electric screw, an angle adjustment mechanism is arranged on the upper end of the sliding seat, a grinding motor is arranged on the angle adjustment mechanism, a grinding wheel is arranged on the output shaft of the grinding motor, a rotating shaft is rotatably arranged at the front and rear ends of the lower side of the body, and wheels are fixed at both ends of the rotating shaft.

[0004] Although the above scheme can conveniently and quickly adjust the inclination angle of the grinding wheel, the device fixes the galvanized steel plate during grinding, which makes it easy to deviate and damage the galvanized layer. At the same time, dust will be generated during the grinding of the galvanized steel plate. The escape of dust can easily pollute the working environment and endanger the health of the operator. Therefore, it does not meet the existing needs. In this regard, we propose a galvanized steel plate post-welding grinding device. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model provides four fixing seats at the middle position inside the main body. After the welded galvanized steel plate is placed on the main body, the knob is turned. The knob causes the threaded rod to rotate synchronously through the rotating shaft. The threaded rod drives the clamping plate to move downward, so that the four corners of the galvanized steel plate can be clamped and fixed. At the same time, the anti-skid pad can be adhered and fixed to the lower end of the clamping plate to improve the anti-skid effect of clamping and fixing, thereby avoiding the deviation of the galvanized steel plate during grinding and avoiding damage to the galvanized layer. The operator only needs to turn the knob to complete the clamping and fixing process. There is no need for complicated operating steps, and it is easy to use.

[0017] 2. The utility model has two dust suction ports at the rear side of the middle position inside the main body, and two dust collecting chambers at the lower end inside the main body. When the galvanized steel plate is polished, the suction machine can be started, and the suction machine will draw out the air inside the dust collecting chamber through the connecting pipe, so that the dust suction port generates suction, and the dust generated by polishing can be sucked into the dust collecting chamber. The dust can be intercepted by the dustproof net, so as to avoid environmental pollution caused by dust escape and harm to the health of the operator. At the same time, the dust collected in the dust collecting chamber can be conveniently cleaned through the sealing doors on both sides, which is easy to use.

[0018] 3. The utility model has a transparent glass plate installed at the front end of the main body. When in use, the galvanized steel plates are loaded and unloaded from both sides of the main body. The transparent glass plate can prevent dust from escaping to the front during grinding, and can also prevent splashes generated by grinding from causing harm to the operator. The design of the transparent glass plate also allows the operator to clearly observe the internal grinding situation, thereby ensuring the safety and accuracy of the grinding process.
