Problems solved by technology

[0005] However, during the working process, the friction between the two grinding base plates and the load is not always the same, resulting in the phenomenon that the rotation speed of the two grinding base plates will be slow or stop, which will affect the grinding efficiency.

Embodiment Construction

[0067] Refer to attached figure 1 , the present invention discloses an eccentrically rotating and oscillating tool 300, such as a sander or a polishing machine.

[0068] The eccentric rotary swing tool 300 includes a support motor 38 (such as figure 2 Shown) the housing 30; the motor 38 contained in the housing 30 and the transmission mechanism driven by the motor 38; and the grinding assembly connected with the transmission mechanism. The grinding assembly may include a first grinding disc assembly 32 and a second grinding disc assembly 34 . When the eccentrically rotating and oscillating tool 300 is working, the two grinding disc assemblies 32 and 34 rotate to grind the workpiece surface. In the description of the present invention, unless otherwise indicated, directional terms, such as front, rear, left, right, up and down, etc., are relative to the direction of normal use of the eccentrically rotating oscillating tool.

[0069] The power source of the eccentrically rot...

Abstract

The invention provides an eccentric rotary oscillation tool. The eccentric rotary oscillation tool comprises a housing, a motor, a transmission mechanism, a first grinding disc assembly and a second grinding disc assembly; the motor is arranged in the housing; the transmission mechanism is driven by the motor; the first grinding disc assembly and the second grinding disc assembly are supported on the housing and driven by the transmission mechanism; the housing is provided with a forced driving mechanism; at least one of the first grinding disc assembly and the second grinding disc assembly is prompted through the forced driving mechanism to rotate around a self-center-line selectively. Accordingly, the cutting stroke of the eccentric rotary oscillation tool is increased and accordingly the grinding efficiency of the eccentric rotary oscillation tool is improved.

Description

technical field [0001] The invention relates to an eccentrically rotating and oscillating tool. Background technique [0002] Conventional eccentrically rotating oscillating tools, such as grinding tools, typically include a grinding shoe. The sanding shoe is connected by suitable gearing to a motor mounted on a housing with one or more handles. The transmission mode is specifically represented by an eccentric shaft driving a circular grinding base plate. When the grinding base plate is working, the eccentric shaft eccentrically drives it to perform circular yaw movement (revolution), and at the same time rotates around the central axis of the grinding base plate. Therefore, the grinding base plate has both revolution and rotation, so that the efficiency of the tool is higher. [0003] However, the grinding bottom plate works in an eccentric state. Due to the centrifugal force of the rotation, the grinding tools will vibrate a lot. This vibration is absorbed by the operato...
