Description

Technical Field

[0001] The utility model relates to a surface treatment device, in particular to a sanding machine. Background Art

[0002] A belt sander is a surface treatment device mainly used for surface grinding, polishing, deburring and precision finishing of metal or non-metal materials. The belt sander works by using an endless belt. The abrasive on the belt can quickly remove unevenness or rust on the material surface to achieve the required smoothness and dimensional accuracy.

[0003] The grinding operation of the existing belt sander is to place the workpiece to be ground on the workbench, then hold the workpiece and push it close to the side of the sanding belt to complete the grinding operation of the workpiece. However, this structure makes the belt sander only suitable for grinding flat workpieces. If the outer surface of a cylindrical workpiece is to be ground, if the workpiece is held and rotated, the grinding thickness of each position cannot be well controlled, resulting in a large error in this grinding operation method, and it is impossible to achieve refined grinding processing, which makes the adaptability of this belt sander poor and the precision of processing cylindrical workpieces low. Utility Model Content

[0006] By adopting the above technical solution, when the plane grinding of the workpiece is to be realized, the workpiece to be processed is placed on the workbench, and then the workpiece is pushed to complete the plane grinding operation. When the outer peripheral surface of the cylindrical workpiece is to be ground, the cylindrical workpiece to be processed is fixed to the rotating clamp, and the movement of the cylindrical workpiece on the rotating clamp is controlled by the sliding component and the rotating clamp is driven to rotate by the driving component to realize the precise and balanced grinding of the outer peripheral surface of the workpiece. The above setting makes the equipment have high processing accuracy and better universal adaptability.

[0007] It is further configured that: the sliding assembly includes a mounting seat fixedly arranged on the frame, a lower sliding seat slidably arranged on the mounting seat along the Y-axis direction, and an upper sliding seat slidably arranged on the lower sliding seat along the X-axis direction, and the rotating clamping member and the driving member are both arranged on the upper sliding seat.

[0008] By adopting the above technical solution, the cooperation between the lower slide and the upper slide can realize the movement of the rotating clamp in the X-axis and Y-axis directions. The movement on the Y-axis is used to adjust the distance between the workpiece and the abrasive belt on the rotating clamp, and the movement on the X-axis is used to adjust the alignment of the workpiece and the abrasive belt on the rotating clamp.

[0009] It is further configured as follows: the rotating clamping member, the driving member and the sliding assembly are all arranged on the frame at the side of the sanding belt replacement operation, and a replacement gap for the sanding belt to pass through and for replacing the sanding belt is formed between the mounting seat and the workbench.

[0010] By adopting the above technical solution, this arrangement allows the above components to be better installed on the frame, and the above components will not interfere with the normal replacement operation of the abrasive belt by setting the replacement gap, so that the structure has better feasibility.

[0011] It is further configured to include a sliding hole formed on the mounting seat and a sliding block fixedly arranged on the lower sliding seat and slidably matched with the sliding hole, wherein the sliding hole extends through the replacement gap to the workbench so that the lower sliding seat can slide from the mounting seat to the workbench.

[0012] By adopting the above technical solution, the sliding hole cooperates with the slider to realize the sliding of the lower slide seat on the mounting seat, and by arranging the sliding hole to extend to the workbench, the movable stroke of the rotating clamp is increased under the premise of limited setting space, so as to adapt to the processing of larger-sized workpieces, making the structure more practical.

[0013] It is further configured that: an adjustment locking assembly for adjusting the movement of the upper slide seat is provided between the lower slide seat and the upper slide seat.

[0014] By adopting the above technical solution, the setting of the locking component is adjusted to achieve precise adjustment of the rotating clamp in the direction, thereby improving the processing accuracy of the equipment.

[0015] It is further configured that the adjustment locking assembly includes an adjustment rack moving with the upper slide seat, an adjustment gear rotatably set on the lower slide seat and meshing with the adjustment rack, a knob rotating with the adjustment gear, a locking tooth slidably set on the lower slide seat, and a spring driving the locking tooth to mesh with the adjustment gear.

[0016] By adopting the above technical solution, the locking tooth is driven to disengage from the adjustment gear, and then the adjustment gear is controlled to rotate by the knob, and the upper slide is controlled to move by the cooperation between the adjustment gear and the adjustment rack, so as to achieve more precise adjustment. When adjusted to the specified position, the force acting on the locking tooth is released to achieve the locking purpose.

[0017] It is further configured that: the rotating clamping member is a three-jaw chuck, and the lower sliding seat is threadedly connected with a locking bolt that presses against the mounting seat.

[0018] By adopting the above technical solution, when the rotating clamp is not in use, it is fixed by a locking bolt to avoid accidents caused by accidental sliding, thereby improving the safety of the device.

[0019] In summary, the utility model has the following beneficial effects: the utility model can realize precise grinding of planes and cylindrical outer peripheral surfaces, has high processing accuracy and has better universal adaptability. BRIEF DESCRIPTION OF THE DRAWINGS
