Description

A circular arc chamfering device for H-shaped steel web grinding

technical field

The utility model relates to an arc chamfering device used for grinding H-shaped steel webs.

Background technique

H-shaped steel includes steel webs and flange plates. During the installation of steel beams and steel columns, backing plates need to be added when the flange plates are welded and penetrated, and the arc chamfering of the steel webs is what needs to be installed. The size space of the backing plate, the traditional processing method of the arc chamfering of the steel web is to grind with a hand-held grinder, which is often time-consuming and laborious, and the grinding efficiency is low. The arc chamfering forming part is regular and asymmetrical, which seriously It affects the appearance of the steel beam, and the manual hand-held grinder has low grinding safety.

Utility model content

In view of the above-mentioned defects, the purpose of this utility model is to provide a kind of arc chamfering device for H-shaped steel web grinding with simple structure, convenient operation, labor-saving, high working efficiency, good forming effect, and ensuring the appearance effect of steel beams. .

The technical scheme that the utility model adopts for this reason is:

It includes a fixed frame, the upper end of the fixed frame is fixedly placed with a steel web, the left side of the fixed frame is provided with a mobile case, the front end of the mobile case is fixedly installed with an adjustable vertical bar, and the front end of the adjustable vertical bar is up and down. Motor brackets are installed at both ends, a motor is fixedly installed on the motor bracket, and a circular grinding wheel grinding head is installed on the output shaft of the motor. on the horizon.

Further, a front baffle and a rear baffle are respectively provided on the front and rear sides of the upper end of the fixed frame, a rotatable screw rod is provided on the rear baffle, a top plate is provided at the rear end of the screw rod, and a top plate is provided on the rear end of the screw rod. The front end is fixed with a hand wheel, and the steel web is located between the top plate and the front baffle.

Further, the adjustable vertical bar is provided with several adjustment holes along the vertical direction, the motor bracket is a right-angle frame, and the vertical plate of the right-angle frame is connected to the adjustment holes on the adjustable vertical bar through bolts.

Further, the lower end of the mobile chassis is equipped with rollers, and the lower end of the rollers is provided with track grooves, the rollers are placed in the track grooves, and the track grooves are parallel to the steel web.

The utility model has the advantages of:

The utility model has the advantages of simple structure, convenient operation, labor-saving, and the purpose of grinding the arc chamfer is achieved by moving the chassis along the guide rail groove to the direction of the steel web, and the forming effect is good, which ensures the appearance of the steel beam; The position on the adjustable vertical bar enables circular chamfering of steel webs of different heights.
