An object of the utility model is to solve above-mentioned problem, provide band saw interface back grinder, it can polish to the saw blade surface, gets rid of saw blade surface crater.
In order to solve the above problem, the utility model discloses a technical scheme as follows:
the back grinding device for the band saw connector is characterized in that an abrasive belt transmission component is arranged inside a shell, a grinding opening is formed in the front side of the shell, the abrasive belt transmission component comprises belt pulleys, an abrasive belt and an extrusion block, the belt pulleys and the extrusion block are arranged on two sides, the abrasive belt is supported by the belt pulleys and the extrusion block, one of the belt pulleys is driven by a rotating motor, the extrusion block is arranged at the grinding opening, a regulating hole is formed in the extrusion block, a fixing bolt penetrating through the regulating hole is fixedly arranged on the shell, a fixing nut compresses the extrusion block, fixing clamping blocks are arranged on two sides of the grinding opening.
The optimization is that the central shaft of the belt pulley which is not connected with the rotating motor is provided with a bearing, and a bearing seat of the bearing is connected with a telescopic rod of the cylinder.
Compared with the prior art, the utility model has the beneficial characteristics that:
(1) the abrasive belt is supported by the belt pulley and the extrusion block, the extrusion block is arranged at the polishing opening, the extrusion block is provided with a regulating hole, the saw blade corresponds to the polishing opening, and the abrasive belt polishes the saw blade; the grinding force between the abrasive belt and the saw blade can be adjusted by adjusting the position of the extrusion block.
The bearing block is connected with a telescopic rod of the cylinder, the position of the belt pulley can be adjusted by the telescopic of the cylinder, and the tightness of the abrasive belt can be adjusted.
The mouth both sides of polishing are equipped with fixed fixture block, are equipped with the saw blade inserted hole on the fixed fixture block, and the saw blade inserts from the saw blade inserted hole, and the saw blade is fixed through fixed fixture block, avoids handheld to ensure that the saw blade is by the degree of polishing unanimous.
The utility model discloses can be used to polish the scar on saw blade surface, ensure saw blade surface smoothness.
