Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
The embodiment discloses a stop device for abrasive band polisher and abrasive band polisher that has this stop device. Wherein the belt sander is a hand propelled three-wheeled belt sander, as shown in fig. 1-3. The abrasive belt sander in the embodiment comprises a frame 5, three pulleys which are arranged in a triangle, an abrasive belt 6 driven by the pulleys, a travelling wheel 7, a handle 4 and a limiting device. For convenience of description, the three pulleys are a first pulley 1, a second pulley 2 and a third pulley 3 respectively, wherein the second pulley 2 and the third pulley 3 are positioned on a straight line, the first pulley 1 is positioned at the upper part of the connecting line of the second pulley 2 and the third pulley 3, the abrasive belt 6 is tensioned and driven to rotate by the three pulleys, and the abrasive belt 6 at the bottom of the second pulley 2 is used for polishing a component by contacting the surface 8 of the component.
For convenient control thickness of polishing, handle 4 sets up in the one end that is close to second band pulley 2, and the bottom of handle 4 is fixed in frame 5, and the top of handle 4 is used for the hand push operation. The walking wheel 7 is arranged at one end close to the third belt wheel 3, and the walking wheel 7 is fixed at the lower part of the frame 5.
In order to adjust the polishing thickness of the component, the embodiment further sets a limiting device on the frame 5, the limiting device comprises a limiting plate 9 as shown in fig. 1, a long through groove is vertically formed in the limiting plate 9, a roller 11 is installed at the bottom of the limiting plate 9, and a bolt 10 is inserted into the through groove of the limiting plate 9 to fix the limiting plate 9 on the frame 5. The limiting device is arranged on one side close to the second belt wheel 2, so that the roller 11 is spaced from the travelling wheel 7 by a certain distance. When the member surface 8 is polished, the abrasive belt 6, the roller 11 and the travelling wheel 7 on the second pulley 2 are jointly contacted with the member surface 8, and after the member surface 8 is polished to a set thickness by the abrasive belt 6, the abrasive belt 6 is no longer contacted with the member surface 8 due to the support of the roller 11 and the travelling wheel 7, and the thickness uniformity of the polished part of the travelling abrasive belt polisher can be ensured by the mode. When the polishing thickness needs to be increased, the fixing plate 9 can be moved upwards to be adjusted in place as shown in fig. 2, then the bolt 10 is locked, at the moment, the distance between the roller 11 and the surface 8 of the member is increased, and the main contact points between the roller 11 and the surface 8 of the member are the abrasive belt 6 and the travelling wheel 7 of the second belt pulley 2, so that the polishing thickness can be increased. If polishing of the component surface 8 is required to be stopped, the fixing plate 9 can be moved downwards to enable the component surface 8 to be in contact with the roller 11 and the travelling wheel 7 only, and the abrasive belt 6 of the second belt pulley 2 is far away from the component surface 8, so that an error polishing accident of the component surface 8 when the equipment is started by mistake can be avoided.
