Description
Technical field
The present invention relates to a kind of motor, it has a rotatable brush plate, and this brush plate is held in the axial direction by a holding device.The invention still further relates to a kind of hand held power machine.
Background technology
Known for motor: its brush plate is supported on the housing base plate of a housing parts rotationally, and brush plate is held in the axial direction by a holding device.
Summary of the invention
The present invention relates to a kind of motor with rotatable brush plate, brush plate is held in the axial direction by a holding device, and wherein, this brush plate has some terminal locations when rotating.
The present invention proposes, holding device with at least one device part with brush plate to remain on its terminal location than the axial motion degree of freedom little between each terminal location.Brush plate can be accomplished between its each terminal location and rotate especially deftly thus, and the operation comfort when this has just strengthened the traffic direction conversion is especially for electric hand-held power tool.High comfortableness is not only arranged, and can reach the especially little freedom of motion of brush plate and assurance contacts reliably with conductor bar on terminal location, described conductor bar forms function by sliding contact and brush plate and is connected.Can advantageously avoid the scaling loss of contact point and the fault of motor.Maintenance work can be reduced, and cost also can reduce.
The invention allows for a kind of hand held power machine that has according to motor in the such scheme.
Propose in addition, holding device is provided with at least one first device part that is used for zone between each terminal location and at least one installs the second device part that is used for terminal location that part is separated with first.Advantageously, these device parts are respectively on purpose designed on a function.The first device part makes brush plate remain in the zone between each terminal location with certain axial motion degree of freedom, this can realize the light activity of brush plate, and can improve comfortableness for the operator, especially its traffic direction can pass through the operation comfort of the hand held power machine of a switching mechanism change.On the contrary, the second device part can seamlessly or with the very little axial motion degree of freedom remain on its terminal location brush plate.Can advantageously avoid the scaling loss on the contact position thus and prevent the fault of motor.
Propose in another configuration of the present invention, the first device part is set on the side that deviates from armature winding of brush plate.This first device part can be set on the grip member of housing parts, especially a hand held power machine, but and on the structure brush plate is remained between the terminal location in the axial direction.Existing structure space can advantageously be utilized, and can realize a kind of installation and the dismounting all especially simply the device, escapable cost, particularly assembly cost.
If the second device part is made of a hook, then brush plate can be simple in structure, seamlessly or with the very little axial motion degree of freedom be clamped on the parts.The use of hook also can realize the clamping of brush plate by contact-making surface little, that save the position.Brush plate can advantageously discharge from its terminal location by very little power consumption, and can improve operator's comfort level.
The second device part can be set on the housing parts or be thought on significant other parts by those skilled in the art.If but the second device part is when being arranged on the brush plate, can realize that then a kind of simple in structure and cost reasonably installs, and wherein only needs two parts to cooperatively interact in order to clamp.Brush plate can be fixed with very little tolerance thus in the axial direction.The second device part can be by being thought that by the professional significant formation power transmission various connected modes chain, form fit and/or that material engages are fixed on the brush plate.If but the second device part is molded on the brush plate, then can saves additional parts, install and consume and cost.
If the second device part is set at one of brush plate radially in the inner region, can utilizes existing structure space and can advantageously utilize existing parts.
The second device part can advantageously act at least a portion of housing on the terminal location in the back.This part can be made of the part of toolroom machine housing or the part of motor field frame.Can avoid parts that add and the tolerance that causes thus.If this part is the part of motor field frame, then brush plate can be by pre-assembled advantageously.
Description of drawings
From describing, following accompanying drawing can obtain other advantage.Express embodiments of the invention in the accompanying drawings.Accompanying drawing and specification comprise a plurality of features in combination.The technical staff can conform with the destination and investigate each single feature and have a mind to the free burial ground for the destitute and be combined into other combination.Accompanying drawing is:
Fig. 1: the summary diagrammatic sketch of an electrical drilling machine of representing with end view,
Fig. 2: the longitudinal section of section II among Fig. 1,
Fig. 3: along the profile of Fig. 2 center line III-III, and
Fig. 4: along the profile of Fig. 2 center line IV-IV.
Embodiment
Fig. 1 represents an electrical drilling machine, and it has a motor that is installed in the housing 22, turns to 24 and select to be clamped at the rotation direction of a cutter 28 in the tool mounting 26 thus by what a selector bar 30 can be selected this motor.Selector bar 30 be set at electrical drilling machine console switch 32 above so that the operator can be with this console switch 32 of a manual manipulation, electrical drilling machine opened or closed and select the required rotation direction 24 of cutter 28 with selector bar 30.On electrical drilling machine one side of tool mounting 26, fixing a first in command 34 on the housing 22 perpendicular to the direction of operating extension.Be provided with the second in command 36 who vertically extends with direction of operating on a side of the housing 22 that deviates from tool mounting 26, it also constitutes the part of housing 22.
The second device part 16,16 ' respectively is arranged on the brush holders 48 of opposition layout diagonally by two, hook in 48 ' the zone constitutes, and these hooks are molded on the radially inner region of brush plate 10 and stretch in the interior space 62 of a winding head 64 (Fig. 3 and 4) with saving the position.The part that the hook of two layouts that oppose diagonally hooks housing 22 respectively in the terminal location of brush plate 10, exactly the housing base plate 42, and brush plate 10 seamlessly is clamped on the housing base plate 42, and the first device part 18 makes brush plate 10 in the degree of freedom that keeps axial motion between the terminal location on axial 14.These hooks can motion in the vacancy 58,60 of housing base plate 42 freely between terminal location.
In principle, brush plate can not be clamped on its terminal location by the inclined-plane is movable in the axial direction yet.These inclined-planes can be molded over brush plate on a side of the first device part or be molded on the brush plate and the first device part.
Brush holder 48,48 ' has the groove that is not shown specifically, and is used to receive carbon brush 50,50 '.Carbon brush 50,50 ' radially inwardly is pressed in (Fig. 2 and Fig. 4) on the commutator 56 by spring part 52,54.
In first service position, brush plate 10 is positioned on first terminal location and the second device part 16 seamlessly is fixed on brush plate 10 on the housing base plate 42.If the operator has operated selector bar 30, then brush plate 10 is rotated on rotation direction 24 by conversion fork 38 and swivel pin 40.Second installs part 16 disengagings cooperates, and brush plate 10 will arrive second terminal location with larger axis to freedom of motion by first of holding device 12 with installing part 18 maintenances always on axial 14.Power on brush board 10 again by the maintenance seamlessly on axial 14 of the second device part 16 ' at second terminal location.
