Description

Steel plate welding area grinding machine

technical field

The invention relates to a grinding tool, in particular to a special grinding machine capable of polishing and grinding the welding area of a steel plate.

Background technique

At present, in the field of mechanical technicians, the welding area of the steel plate must be polished before welding, otherwise it will affect the strength of the welding. The traditional grinding operation is to use an angle grinder to grind the welding area of the steel plate, but the use of the angle grinder is purely manual work, so it is difficult to ensure the flatness of the grinding area, which affects the quality of the product. In addition, when the steel plate to be polished is long, the operator must use the angle grinder to perform the grinding operation in a squatting manner. The long-term operation is labor-intensive, the operator is prone to fatigue, and the production efficiency is low.

Contents of the invention

The problem to be solved by the present invention is to provide a steel plate welding area grinder, which can ensure the flatness of the welding area, high product quality, low labor intensity and high production efficiency by using the grinding machine to grind the steel plate welding area.

In order to solve the above problems, the following solutions are adopted:

The feature of the steel plate welding zone grinding machine of the present invention is that it includes a workbench, which is in the shape of a rectangular plate with longitudinal baffles on its two opposite long sides. There is a vehicle frame above the workbench, with a handle on the vehicle frame, and rollers on both sides of the vehicle frame. The rollers on both sides fall on the inside of the baffles on both sides of the workbench respectively, and the distance between the two baffles is equal to the distance outside the two rollers. . An electric motor, an adjusting mechanism and a working wheel are fixed on the vehicle frame, a driving wheel is arranged on the electric motor, and a driven wheel is arranged on the adjusting mechanism. The driving wheel, the driven wheel and the working wheel are arranged vertically and the centers of gravity of the three are located on the same vertical plane. An abrasive belt is set on the outside of the driving wheel, the driven wheel and the working wheel so that the driving wheel, the driven wheel and the working wheel The wheels can rotate synchronously.

A further improvement of the present invention is that there are vertically arranged guide columns on both sides of the vehicle frame, and horizontal guide wheels on the lower section of the guide columns, and the distance between the baffles on both sides of the workbench is equal to two Spacing outside the guide wheels. This improvement can ensure that the axes of the two rollers are always perpendicular to the longitudinal direction of the workbench when the vehicle frame is running on the workbench.

A further improvement of the present invention is that a protective cover is fixed directly above the abrasive belt on the vehicle frame, thereby preventing steel shavings from splashing upward during the grinding process and ensuring the safety of operators.

A further improvement of the present invention is that at least two pairs of pressure blocks are arranged on the workbench at symmetrical positions on both sides of the center line of the running track of the frame working wheel, so as to fix the steel plate to be polished.

Adopting the above scheme has the following advantages:

Because the grinding machine for the steel plate welding area of the present invention has a workbench, there is a vehicle frame that can move along the longitudinal direction on the workbench, and a motor is arranged on the vehicle frame, and the motor can drive the working wheel and the abrasive belt to rotate. Put the steel plate on the workbench in the area below the working wheel, turn on the power of the motor, and then push the frame to move longitudinally along the workbench. During the movement, the abrasive belt on the workwheel will grind the steel plate. During the grinding process of the grinding machine, the height of the working wheel is always kept constant, so as to ensure the flatness of the grinding area and the quality of the product. Moreover, with the grinding machine, the operator only needs to push the frame without squatting down, so the labor intensity is small, fatigue is not easy, and the production efficiency is high.
