Definitions
- the present invention is based on a hand tool according to the preamble of claim 1.
- the handheld power tool with the features of claim 1 has the advantage that the loads and wear on the motor and motion transmission components are lower and the overall efficiency and the service life of the handheld power tool are significantly improved.
- the drive is designed as a hydraulic or pneumatic cylinder, it can be controlled particularly precisely.
- the tool is an insert tool, it can easily be exchanged for different tools for different purposes.
- gearbox is a coupling or stepping or cam gear
- the hand tool is designed as a planer or hand milling machine, as a drilling machine, hammer drill, hammer, as an orbital, eccentric or angle grinder, as a circular or reciprocating saw, as a scraper or as scissors, you can help with the corresponding, specific work energy-saving and wear-reducing movement types can be set at lightning speed for the respective hand tool if the tool does not engage in the workpiece.
- FIG. 1 shows a three-dimensional side view of a hand-held saw machine according to the invention
- FIG. 2 shows a longitudinal section of the hand-held saw machine according to FIG. 1
- FIG. 3 shows a typical movement curve of the desired non-uniform tool movements.
- FIG. 1 shows a hand-held saw 10 with an elongated housing 11, the rear area of which serves as a motor housing 12 and the front area of which serves as a gear housing 14.
- a power connection cable 16 emerges from the rear of the motor housing 12 and an elongated saw blade 18 that can be moved back and forth or back and forth from the transmission housing 14 at the front.
- FIG. 2 shows a longitudinal section of the hand-held saw 10 according to FIG. 1, an electric motor 20 mounted in the motor housing 12 and serving as a drive, with a motor shaft 24 which can be coupled to a transmission input shaft 23 which belongs to a transmission 22 which is in the transmission housing 14 of the hand-held saw 10 is stored.
- An output tappet 26 emerging from the gear 22 on the left in the viewing direction executes a straight forward and backward movement, which is transmitted to the saw blade 18 and is represented by the movement arrow 28.
- a servo motor or a stepper motor, but also a hydraulic or pneumatic cylinder with a corresponding control device can serve as the drive.
- the gear 22 can be a spur gear with non-circular gears, or a toothed belt gear with non-circular toothed belts or as a coupling gear or stepping gear or cam gear.
- the non-uniformity of the movement is determined by the dimensioning or setting of the aforementioned types of gears.
- both separately generated forms of acceleration can be generated by both the drive and the gearing can be combined with each other to create a wide variability of the initial movement on the tool.
- the lifting movement of the scraper tool can be carried out quickly with low torque and the subsequent retraction without workpiece intervention.
- the cutting stroke of the shear jaws can be carried out with high torque and slow speed and the return movement for opening with high speed and low torque can be carried out.
- the working stroke is at lower speed and higher torque than the idle stroke
- the saw blade does not intervene, while routing, vibratory and eccentric grinders, angle grinders, circular saws and the like.
- the superimposition of a pulsating over the uniform rotating movement improves the working behavior, e.g. in the case of sensor-controlled, quasi-automatic reduction of power or torque if the associated tools do not engage in a workpiece.
- a gearbox can be connected between the motor and the tool, or the energy can be passed on directly to the tool.
- Gear units operating in a non-uniform manner will be combined with both a uniformly rotating and a non-uniformly rotating drive.
- FIG. 3 shows the waveform of a periodically non-uniform rotary movement as a path-time curve display. For example, with rapid turning in idle stroke when the reciprocating saw blade is retracting and with slow, powerful turning during the working stroke when the workpiece saw engages with the reciprocating saw blade. It goes without saying that the invention is not restricted to hand-held machine tools, but can also be used without any problems for stationary machine tools.
