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 the attached figure 1 , the present invention discloses an eccentric rotating and oscillating tool 300, such as a sanding machine or a polishing machine.

[0068] The eccentric rotary oscillating tool 300 includes a support motor 38 (eg figure 2 shown) housing 30; a motor 38 housed in the housing 30 and a transmission mechanism driven by the motor 38; and a grinding assembly connected with the transmission mechanism. The grinding assembly may include a first grinding disk assembly 32 and a second grinding disk assembly 34 . When the eccentric rotary oscillating tool 300 works, the two grinding disc assemblies 32 and 34 rotate and 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 eccentric rotary oscillating tool.

[0069] The power source of the eccentric rotary swing type tool 300 is ...

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] 本发明涉及一种偏心旋转摆动类工具。 Background technique [0002] 传统的偏心旋转摆动类工具,例如磨砂类工具,通常包括一个打磨底板。 打磨底板通过适当的传动方式连接到马达上,而马达安装在带有一个或多个手柄的壳体上。 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. 因此,打磨底板既有公转又有自转,使得工具的效率较高。 [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 operator's hands and arms, which will have a serious impact on the health of the operator. as a result of. Manufacturers and users of abrasive tools therefore wish to eliminate or reduce the vibration transmitted to the operator, thereby improving worker safety and productivity. [0004] 因此,业界技术人...
