Problems solved by technology

However, the sawtooth used in traditional electric saws often uses the drive cylinder to drive the slider to move up and down for the drive mechanism that drives the spark machine to reciprocate up and down. However, the precision of this structure is not very high, and some require high precision. The products of this kind of driving mechanism cannot meet the precision requirements

Embodiment Construction

[0014] Such as figure 1 From the schematic diagram shown, it can be known that the sawtooth driving mechanism for an electric saw of the present invention can drive the main shaft 1 to reciprocate up and down, including the driving slider 5, the driving guide rail 4 and the proximity switch.

[0015] Drive guide rail 4 has a pair, is symmetrically installed on the side wall of gantry 10, and the two ends of drive slide block 5 are respectively installed on two drive guide rails 4, and can be driven by drive unit and move up and down.

[0016] In the present invention, the driving device has two types of driving. The first driving device is a linear motor, which is installed on the gantry 10 and whose lower end is connected with the driving slider 5 .

[0017] The second kind of driving device is a driving screw 2, the upper end of the driving screw 2 is connected with the driving motor, and can be driven by the driving motor to rotate, the driving motor is installed on the upp...

Abstract

The invention relates to a sawtooth driving mechanism for an electric saw, which includes a driving slider, a driving guide rail and a proximity switch; the driving guide rail has a pair, which are symmetrically installed on the side wall of the gantry frame, and the two ends of the driving slider are respectively installed on two on a driving guide rail, and can be driven by the driving device to move up and down; the proximity switch is installed on the side end of the driving slider, and at the same time, a contact plate used with the proximity switch is also provided on the gantry frame. There is also a scale plate, and the contact plate can be adjusted up and down according to the scale of the scale plate. The advantage of the invention is that the device can provide a basis for precise control of the working stroke of the main shaft.

Description

technical field [0001] The invention relates to an electric tool, in particular to a sawtooth driving mechanism for an electric saw. Background technique [0002] Chainsaw, also known as "power saw", was invented by German Andreas. Invented by Steele in 1926, it greatly saves the time and labor spent on cutting materials. A chainsaw is powered by electricity and is a cutting tool used to cut wood, stone, steel, etc., with sharp teeth on the edge. Separate fixed and portable, the saw blade is generally made of tool steel, there are round, strip and chain and so on. [0003] At present, in the process of processing the circular saw blade, a spark machine is used for the processing of its planar structure. However, the sawtooth used in traditional electric saws often uses the drive cylinder to drive the slider to move up and down for the drive mechanism that drives the spark machine to reciprocate up and down. However, the precision of this structure is not very high, and so...
