Abstract
The invention relates to a machine tool, in particular, a hand-held machine tool, comprising a tool (18) which can be displaced by a drive, in particular, a motor (20). The aim of the invention is to increase efficiency, reduce energy consumption and increase the service life of said machine. Said drive is an electomotor which rotates in a uniform manner, and the movement thereof is converted by a gear mechanism (22) into a non-uniform movement and is transmitted to the tool (18).
Description
Technical field
The present invention relates to a kind of hand held power machine of the preamble according to claim 1.
Background technology
A kind of keyhole saw (Stichsaege) with a linear motor is disclosed in DE 102 30 726 A1, this linear motor can make cutter carry out motion adjustable, that be accelerated unevenly, so that this cutter respectively can be lentamente with higher torque or apace to move than the low torque adjustable ground when acting on workpiece at every kind of processing situation.
Linear motor firm, that can be used for hand held power machine is for too heavy and too expensive the extensive use in hand held power machine.
Summary of the invention
Hand held power machine with the described feature of claim 1 has such advantage, i.e. load on motor and the motion transferring elements and wearing and tearing are littler and are improved significantly in gross efficiency and service life hand held power machine.
By using a kind of motor that can be especially accurately controlled, firm can in specific hand held power machine, save common in other cases transmission device.
By drive unit being configured to hydraulic pressure-or pneumatic linear actuator, this drive unit can be especially accurately controlled.
Cutter is an insertion tool, and then it can easily be changed with different cutters mutually at different application targets.
By using a kind of motor traditional, that evenly rotate, the transmission device that moves through of this motor is changed in this wise, make uniform motor motion for example be converted into the uneven output movement of transmission device by non-circular gear or non-round cog belt, then can be with lower, more firm motor of a kind of cost and transmission combination special, that can select individually, by this transmission device especially load of conserve energy and reduction force transmission element when dallying for every type hand held power machine.
This transmission device is link gearing or divides gear stage (Schrittgetriebe) or cam gear that then this cutter can be driven with periodically uneven motion.
The transmission device of a motor of Qu Donging and a uneven motion of same generation is combined unevenly, and then adjustable ground is realized a plurality of uneven motion schemes on cutter, to realize the best progress of work in nearly all possible working condition.
By with hand held power machine as planing machine or hand-held Milling Machine, as drilling machine, hammer drill, jump bit, as superfine milling machine, eccentric milling drum or angle grinding machine, as annular saw or linear reciprocating motion saw, constitute as drag scraper or as cutter, utilizing corresponding hand-held tool to carry out when cutter affacts on the workpiece, can not being adjusted to conserve energy and motion mode minimal wear apace in the corresponding special processing.
Description of drawings
Explain the present invention according to an embodiment and affiliated accompanying drawing below.
Accompanying drawing is represented:
Fig. 1 is according to the three-dimensional side view of hand-held linear reciprocating motion saw of the present invention,
Fig. 2 is according to the longitudinal sectional drawing of the hand-held linear reciprocating motion saw of Fig. 1, and
The typical motion curve of tool motion that Fig. 3 tries hard to reach, uneven.
The specific embodiment
Fig. 1 illustrates the hand-held linear reciprocating motion saw 10 that has an elongate housing 11, and the back region of housing is used as gear mechanism housing 14 as the front area of motor field frame 12 and housing.
Stretching out from motor field frame 12 rear portions that an electric current connects cable 16 and stretch out one from gear mechanism housing 14 fronts can be back and forth or saw blade 18 that seesaw, microscler.
Fig. 2 with the longitudinal profile according to the hand-held linear reciprocating motion saw 10 of Fig. 1 illustrate one be bearing in the motor shell 12, as motor 20 drive unit, that have a motor shaft 24, this motor shaft 24 can join with transmission device power shaft 23 couplings, this transmission device power shaft belongs to a transmission device 22, and this transmission device is bearing in the gear mechanism housing 14 of hand-held linear reciprocating motion saw 10.
The driven push rod (Abtriebsstoessel) 26 that stretch out from transmission device 22 on the left side on direction of observation carries out seesawing of straight line, and this seesaws to be passed on this saw blade 18 and by motion arrow 28 and illustrates.Servomotor or stepping motor can be used as drive unit, but hydraulic pressure or pneumatic linear actuator with corresponding adjusting device also can be used as drive unit.
Therefore, for example not only ballistic motion in hammer drill, be the axially-movable of hammer drill but also its rotation can be unevenly, change the ground configuration.
In the planing machine, rotate Knife for stripping cable if utilize less peripheral speed and higher torque in the time of on affacting workpiece, but Knife for stripping cable is rotated under the situation of the torque of minimum quickly in the not zone of action of Knife for stripping cable, and then Pao Xiao efficient can be improved by the irregular motion of Knife for stripping cable.
In drag scraper, the linear reciprocating motion of Shave tool can carry out with high torque forward and the backhaul that then do not act on the workpiece can be carried out fast and with very little torque.
In cutter or nibbler, the cutting stroke of shear shank can with high torque and the speed of waiting a moment carry out and the backhaul that is used to open can with at a high speed and little torque carry out.In the goose saw machine, the processing stroke can carry out with lower speed of the idle stroke of not doing the time spent than saw blade and higher torque, and engraving machine (Oberfraesen), super smart-and eccentric milling drum, angle grinding machine, annular saw and similar tool machine in, the stack of the motion of carrying out with the form of pulse during Rotating with Uniform has improved service behaviour, for example under situation with sensor control, when affiliated cutter did not act on the workpiece, power or torque standard automatically reduced.
In the drive unit that drives unevenly, can between motor and cutter, connect a transmission device or energy is directly passed to cutter.The transmission device of inhomogeneous work will be not only and the drive unit of even rotation but also combined with the drive unit of inhomogeneous rotation.
Fig. 3 illustrates the oscillating curve as rotational motion displacement time curve, the inhomogeneous variation of periodicity.For example the idle stroke high speed when the returning of linear reciprocating motion saw blade is rotated and is effectively rotated at a slow speed in the impulse stroke when the linear reciprocating motion saw blade acts on the workpiece.
Self-evident, the present invention is not limited on the hand held power machine, but the lathe that can be used for fixing without difficulty.
