The lower part of the annular abrasive belt is extruded by the graphite rod, so that a larger area with polishing pressure can be formed on the abrasive belt, the polishing efficiency is improved, powder generated after polishing is sucked away by the dust suction device, dust flying is avoided, and the probe can judge the smoothness of the surface of a workpiece.
Description
Technical Field
The present utility model relates to a polishing tool for polishing an object surface by a robot to make the object surface smoother or rougher.
Background
Most of tools for polishing the surface of an object by using a mechanical arm fixed grinding tool are rotary table type tools, and the rotary table type tools have poor polishing flatness due to the linear speed difference of each position of a rotary table in the rotating process; the linear speed near the center is low in efficiency, the outer edge is sharp and is easy to scratch the workpiece, and the area of the sand disc actually contacted with the workpiece is small and low in efficiency.
CN103495921a discloses an automatic polishing device, which comprises a workbench, a conveyor belt arranged on the workbench and at least one polishing mechanism arranged above the conveyor belt, wherein the polishing mechanism comprises a driving wheel and a driven wheel which are respectively arranged on two sides of the conveyor belt, a polishing motor connected with the driving wheel and used for providing power for the driving wheel, and an abrasive belt wound on the surfaces of the driving wheel and the driven wheel; the abrasive belt is wound and connected with the driving wheel and the driven wheel and is contacted with the polished material to form a polished plane. Through setting up the layering, increase the area of polishing, improve the efficiency of polishing. However, the abrasive belt is tightly contacted with the pressing bar, so that the pressing bar is seriously worn, and the preset polishing pressure cannot be applied to the abrasive belt by the pressing bar, so that the polishing effect is greatly reduced.
Disclosure of Invention
The utility model aims to provide a surface polishing tool with higher polishing efficiency.
The surface polishing tool comprises a base, a driving roller and a driven roller which are arranged on the base, wherein the driving roller is connected with a motor, and an annular abrasive belt bypasses between the driving roller and the driven roller.
Preferably, the base is provided with a dust collection port connected with the negative pressure dust collection device.
The flatness detection device is arranged at the rear end of the base and comprises a probe which contacts a workpiece, the probe is connected with a lifting arm, a magnet is arranged on the lifting arm, and the magnet is close to a coil fixed on the device.
According to the utility model, the lower part of the annular abrasive belt is extruded by the graphite rod, so that a larger area with polishing pressure can be formed on the abrasive belt, the polishing efficiency is greatly improved, powder generated after polishing is sucked away by the dust suction device, dust flying is avoided, a workpiece is polished, the probe moves on the surface of the workpiece to move up and down along with the concave-convex change of the workpiece, and an electric signal with amplitude and frequency is formed by cutting a coil through magnetic force lines of a magnet, so that the smoothness degree of the surface of the workpiece can be judged.

Description of the embodiments
The surface grinder as shown in the figure has a base 1, and the base 1 is provided with a connection port 11 for connecting a grinding manipulator. The driving roller 2 and the driven roller 3 are mounted on the base 1. The driving roller is connected with a motor 21, and is driven to rotate by the motor 21. An endless abrasive belt 4 is sleeved between the driving roller 2 and the driven roller 3, and is driven by the driving roller 2 to bypass between the driving roller 2 and the driven roller 3. A pressure is formed on the lower roller surfaces of the driving roller 2 and the driven roller 3 to rub the surface of the workpiece, thereby polishing the workpiece. A graphite rod support 5 is arranged at the gap between the driving roller 2 and the driven roller 3, the graphite rod support is fixed on the base 1, a plurality of graphite rod pore canals 51 are arranged in the graphite rod support 5, graphite rods 52 are respectively arranged in each graphite rod pore canal 51, a pushing spring 53 is arranged at the upper end of each graphite rod 52, and the lower end of each graphite rod 52 is contacted with the extrusion annular abrasive belt 4. In the process that the annular abrasive belt 4 bypasses the driving roller 2 and the driven roller 3, the graphite rod 52 generates downward pressure on the annular abrasive belt 4, so that effective polishing is formed at the end part of the graphite rod 52, the effective polishing area of the annular abrasive belt 4 is greatly increased, and the polishing efficiency is improved.
The base 1 is provided with a dust collection port 6 which is connected with a negative pressure dust collection device through a pipeline connecting end 61. The dust collection port 6 is positioned at the rear of the advancing direction of the polishing tool, and dust generated after polishing is sucked into the dust collection device from the dust collection port 6 for filtering treatment, so that dust flying is reduced.
The rear end of the base 1 is provided with a flatness detecting device 7, the detecting device 7 comprises a probe 71 with the end part contacting the surface of the workpiece, the probe 71 is connected with a lifting arm 72, the lifting arm 72 is provided with a magnet 73, and the magnet 73 passes through a coil 74 fixed on the support 1. During the movement of the polishing tool, the probe 71 moves along with the polishing tool, and as the lower portion of the probe 71 contacts the surface of the workpiece, the probe can vibrate along with the rough condition of the surface of the workpiece, so that the magnet 73 vibrates in the coil 74 in a fluctuating manner, and therefore, the coil 74 generates an electric signal with amplitude and frequency, the roughness of the surface of the workpiece can be known, and whether the workpiece is polished repeatedly or repeatedly can be judged.
An embodiment of the present utility model is described above with reference to the drawings, but the present utility model is not limited to the above embodiment. Various modifications are possible within the scope of the technical idea of the present utility model, and they all fall within the scope of the present utility model.
