Problems solved by technology

[0004] However, after using the fine-tuning motor, the safety of the fine-tuning motor is also a factor that needs to be considered
If after the working parts are rotated to the appropriate position, due to the operator's misoperation, the arm or workbench that has been locked and fixed by the locking device is driven by the fine-tuning motor to rotate, then the fine-tuning motor will output When the torque is blocked, it is easy to cause overheating damage and cause unnecessary losses
Although the usual motor itself also has the function of overheating protection, under the above circumstances, the torque of the fine-tuning motor has been kept in the output state, and mechanical loss is inevitable, and it may still be damaged.

Embodiment Construction

[0034] 1 to 3, the desktop tool disclosed in the present invention is a miter cutting machine, including a base 1, a worktable pivotally connected to the base 1, a machine arm 3 pivotally connected to the worktable 2, and The working head 4 at the free end of the arm 3, where the working head 4 is a saw head, is driven by a main motor to rotate and work. The workbench 2 and the base 1 are pivotally connected together by a first pivot 21, so that the workbench 2 can be rotated in a horizontal direction; the arm 3 and the workbench 2 are pivoted by a second pivot 22 The ground is connected together so that the arm 3 can be rotated in the vertical direction.

[0035] In order to precisely control the rotation angle of the worktable 2 and the arm 3, both of them are controlled by a fine-tuning motor 5. Here, the arm 3 adopts the fine-tuning motor 5 as an example for description. The fine-tuning motor 5 is arranged inside the workbench 2, and is electrically connected to the controller...

Abstract

The invention provides a table-typed tool, comprising a base (1), a workbench (2), a machine arm (3) and a working head (4). At least a group of slight adjusting transmission mechanism and locking device are arranged between the base (1) and the workbench (2) or between the machine arm (3) and the workbench (2); furthermore, the slight adjusting transmission mechanism is driven to rotate by a slight adjusting motor (5); each group of slight adjusting transmission mechanism and locking device comprise a motor protection device (9, 10, 11); when the locking device is in locking state, the motor protection device (9, 10, 11) can avoid the overloading of the slight adjusting motor (5).

Description

Technical field [0001] The invention relates to a desktop tool, in particular to an oblique cutting machine. Background technique [0002] In desktop tools, there are usually two types of angle adjustments for working parts: manual and electric. For example, in the oblique cutting machine, the operator can manually adjust the workbench or the arm of the oblique cutting machine manually, and make the two rotate in the horizontal or vertical direction to achieve the inclination angle required by the operator. The standard used in the adjustment process is to refer to the scale marked on the workbench. After the above-mentioned working parts are rotated to an appropriate angle, they are fixed by the locking device. Since the entire adjustment process is man-made, the accuracy is poor. [0003] In the desktop tool using electric angle adjustment, the problem of poor accuracy is solved. Chinese Patent Application Publication CN1253866 discloses a miter saw operating table, which inclu...
