Problems solved by technology

Its disadvantages: Since there is a joint between the endless belt type abrasive belt on the sanding contact roller and the passive roller, and the abrasive belt can only rotate circularly, it is inevitable to produce horizontal lines on the workpiece to be ground, which directly affects the grinding quality , especially for the grinding of the paint surface, the horizontal stripes are particularly prominent and unavoidable, which is an international technical problem in the industry

Embodiment 1

[0010] Embodiment 1: with reference to attached figure 1 . The broadband vibrating abrasive belt grinding head is composed of a vibrating grinding head 3 and a vibration source 2, and the vibration source 2 drives the vibrating grinding head 3 to vibrate and grind. The vibration source 2 is electric vibration, pneumatic vibration, magnetic vibration, hydraulic vibration or high frequency vibration. The electric vibrating mechanism adopts a motor to drive the vibrating mechanism to vibrate at low frequency, medium frequency or high frequency, and the vibrating mechanism drives the broadband vibrating grinding head to vibrate. Pneumatic vibration is the use of compressed air to drive the vibrating pneumatic components to generate low-frequency, medium-frequency or high-frequency vibrations. The vibration mechanism drives the vibration of the broadband vibrating grinding head. Its production technology is a prior art and will not be described here. Magnetic vibration is to use ...

Embodiment 2

[0011] Embodiment 2: On the basis of Embodiment 1, the vibration source 2 is installed in the vibration grinding head 3 .

Embodiment 3

[0012] Embodiment 3: On the basis of Embodiment 1, the high-frequency oscillator and the broadband vibration grinding head have an integral design structure, and directly generate low-frequency, intermediate-frequency or high-frequency vibrations after starting.

Abstract

The present invention relates to wide belt vibrating grinding head and grinding method for sander and belongs to the field of sander assembly manufacturing. The ground workpiece is made to contact with the sanding surface of sand belt in the sand belt delivering and withdrawing mechanism and the wide belt vibrating grinding head in the back side of the sanding surface is started to grind the workpiece. The present invention has the advantages of greatly raised workpiece surface grinding precision, no trouble of sand belt junction and low power consumption.

Description

Technical field: [0001] The invention relates to a broadband vibrating grinding head of a sanding machine and a grinding method, which belong to the field of sanding machine assembly manufacturing. Background technique: [0002] The applicant is currently producing and selling sanding machines. The grinding mechanism of the sanding machine is an endless belt-type rotating structure in the same direction. The structure is composed of a sanding contact roller, an abrasive belt, and a passive roller. On the roller and the driven roller, the abrasive belt is driven to rotate in the same direction by the sanding contact roller. Its disadvantages: Since there is a joint between the endless belt type abrasive belt on the sanding contact roller and the passive roller, and the abrasive belt can only rotate circularly, it is inevitable to produce horizontal lines on the workpiece to be ground, which directly affects the grinding quality , especially for the grinding of the paint surf...
