Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.

Referring to fig. 1-3, the belt sander convenient for grinding control is provided with a driving device and a grinding mechanism connected with the driving device, wherein the driving device is provided with a base 14, and a driving wheel 15 and a driven wheel 16 which are fixed on the base 14 at intervals. The grinding mechanism comprises a grinding platform 1 with a certain length and a waist hole shape, wherein two ends of the grinding platform 1 are respectively provided with a roller 2, an abrasive belt 3 is sleeved on the outer rings of the roller 2 and the grinding platform 1, and the roller 2 on one side is connected with a driving device (a driven wheel 16) for driving. In order to facilitate higher grinding precision during grinding, an auxiliary device for grinding control is arranged on the grinding platform 1, and the auxiliary device can control the depth of contact between a workpiece to be ground and the abrasive belt 3 during grinding, so that the grinding precision is improved; meanwhile, the grinding angle of the workpiece to be ground can be adjusted so as to meet different grinding requirements.

Specifically, the auxiliary device comprises a U-shaped bracket 4 transversely arranged at the upper part of the grinding platform 1, and an adjusting device which is adjustable towards the surface of the abrasive belt 3 and is used for clamping a workpiece to be ground is arranged on the U-shaped bracket 4. The adjusting device comprises a height rod 5 which is vertically arranged on a U-shaped support 4 in a sliding and penetrating mode, wherein a clamp 6 which rotates along a vertical surface is arranged at the bottom of the height rod 5 (the manufacturing can be selected according to the shape of an actually ground workpiece), a fastening bolt 7 which is used for positioning the height rod 5 is arranged on the U-shaped support 4 in a penetrating mode, and a fastening device which is used for rotationally positioning the clamp 6 is arranged at the bottom of the height rod 5. The grinding depth of the workpiece to be ground and the surface of the abrasive belt 3 is adjusted through the fastening bolt 7, the grinding depth of the workpiece to be ground is fixed through the fastening bolt 7 after the adjustment is completed, and after the grinding is completed, the whole grinding surface of the workpiece to be ground has accurate grinding depth and surface smoothness, so that the problem of unstable grinding depth caused by manual operation is solved. In order to facilitate the intuitive adjustment of the depth, it is preferable that a height gauge 14 is provided on the sidewall of the height rod 5 for quickly and accurately adjusting the height rod 5.

Preferably, the fastening device comprises a screw rod 11 transversely penetrating through the bottom of the height rod 5, a first U-shaped bracket 12 is rotatably sleeved on the screw rod 11, a nut 13 for positioning and fastening the first U-shaped bracket 12 is sleeved at one end of the screw rod 11, and the clamp 6 is arranged at the bottom of the first U-shaped bracket 12. Meanwhile, the side wall of the first U-shaped bracket 12 can be set to be a triangular tip shape, and a protractor 17 (shown in fig. 3) which is correspondingly adjusted to match the triangular tip shape is arranged on the side wall of the height rod 5.
