Description
Technical field
The present invention relates to a kind of motorised hand-held grinding tool, especially superfine milling machine, have an abrasive sheet bearing and be used for abrasive sheet is remained on clamping device on this abrasive sheet bearing regularly, wherein these clamping devices comprise clamping camber members that have two clamping limbs that connect by a traversing section.
Background technology
Disclose some motorised hand-held grinding tools by prior art, they are provided with one and have closed arched automatic back clamping system.
But on these known motorised hand-held grinding tools, this bow-shaped structural has complicated shape, so that this arched manufacturing cost height.Fixing to clamp of sand paper always needs some handgrips on these external these known motorised hand-held grinding tools, therefore, wishes that still operation is more comfortable, more saves time at this.
Summary of the invention
According to the present invention, a kind of motorised hand-held grinding tool, especially superfine milling machine have been proposed, have an abrasive sheet bearing and be used for abrasive sheet is remained on clamping device on this abrasive sheet bearing regularly, wherein these clamping devices comprise a clamping camber member that has two by the clamping limb of a traversing section connection, and wherein: this traversing section and these clamping limbs are set in the plane.
By contrast, motorised hand-held grinding tool of the present invention has its advantage, and promptly bow-shaped structural has simpler shape.
Be configured to simple, straight line segment and being arranged in the plane with clamping limb thus by the traversing section that will clamp camber member, this clamping camber member can especially easily be formed by single wire spare bending.This has just reduced the manufacturing cost according to motorised hand-held grinding tool of the present invention.
In addition, hand-guided grinding preferably has a clamping camber member locking system that has operating lever, and wherein this operating lever has a stop device that is used for locking clamping camber member in the centre.Particularly advantageous is that this operating lever has one and is used for the press surface that release clamps camber member.This press surface embodies additional operation ease when taking out an abrasive sheet that has worn and torn when opening clamping device.In fact, the user only needs to push this press surface in order to open clamping device.Clamping camber member then automatically ejects from locking.That is to say,, only need a very brief process of pushing in order to open this clamping device.Set press surface makes this operation become simple especially, because it shows to the user what position he must push.This press surface that meets human engineering has guaranteed that also the user can apply a suitable pressing force on a rational position.
Advantageously, this press surface is set at the top of stop device.
Advantageously, this stop device is a locking projection.
Favourable in addition also is, in the motorised hand-held grinding tool with long clamping camber member structure according to the present invention, the abrasive sheet bearing has one or more support chips at sidepiece.When this motorised hand-held grinding tool work, can suppress to clamp the oscillating movement of camber member thus.
Description of drawings
To describe embodiments of the invention in detail by accompanying drawing in the following description.
Fig. 1 shows the perspective view of a clamping device according to the present invention under clamped condition.
The specific embodiment
Clamping device 100 in the figure comprises an abrasive sheet bearing or a grinding plate 101, and it carries all parts of this clamping device 100.This clamping device 100 has a front clamp device 102 and a rear fixture 103.These clamping devices 102 and 103 are respectively applied for and clamp the also leading section and the rearward end of an abrasive sheet of tensioning.This front clamp device 102 is configured to have the centering type sand paper clamping device of reloading spring.This rear fixture 103 is configured to clamp.
A critical piece of this clamping device 100 is to clamp camber member 104.At this, the rear section of this clamping camber member 104 disposes to rear fixture 103, and the forward part of this clamping camber member 104 disposes to front clamp device 102.This clamps camber member 104 and is made up of the single wire parts of respective curved.
This clamping camber member 104 has two clamping limb 105a and 105b, and they are connected to each other by a traversing section 106.This traversing section 106 is simple straight wire sections that are not bent that clamp camber member 104.In the case, described relatively two clamping limb 105a of this traversing section 106 and 105b are positioned at same plane with meeting at right angles.
This front clamp device 102 has spigot surface or the bump 107a and the 107b of two side direction, and they are used to clamp the location or the guiding of camber member 104.These bumps 107a and 107b respectively are engaged in the described right angle part, and these right angle parts are made of the transition portion between corresponding clamping limb 105a or 105b and the described traversing section 106.
This clamps, and camber member 104 passes through locking system or stop device, exactly locking projection 108 keeps its position on front clamp device 102.This be achieved in that be traversing section 106 be engaged in locking projection 108 below.This locking projection 108 is being installed on the flexible operating lever 109 medially.On this operating lever 109, above locking projection 108, be provided with an elliptoid press surface 110.The surface of this press surface 110 is processed into coarse, adheres to better with the finger that guarantees the user.The vertical axis that this press surface 110 is configured to relative operating lever 109 tilts.
Also be provided with an additional support member 111 on abrasive sheet bearing 101, this support member is used for the support of clamping limb 105b and guiding.This support chip 111 also can be set in place on the side on opposite, is used for propclip gripping arm 105a, although not shown.
The operation principle of clamping device shown in this Fig 100 below will be described.
Sand paper insert and tensioning as in the prior art in known manner method carry out.But shown in clamping device 100 on obtain following specific function:
Shown in form of implementation in, the back tensioning process of sand paper is just finished before in described clamping camber member 104 snaps in described front clamp device 102.
Be pressed in the locking system 108 by clamping camber member 104, additionally utilize the elastic force that clamps camber member 104, to support the eccentric tension force of front clamp device 102.
In order to open clamping device 100 and to take off the abrasive sheet that has worn and torn, the press surface 110 of pressing operation lever 109 above the traversing section 106 that clamps camber member 104 ejects from its locking so that clamp camber member 104.Discharged the clamp of rear fixture 103 thus and sand paper is ejected from rear fixture 103.
Be embodied as straight cylindrical sector by the traversing section 106 that will clamp camber member 104, clamping camber member 104 can be made especially simply.Especially do not need traversing section 106 is provided with additional bending and wreath piece.
Traversing section 106 is maintained at the state of clamping by a unique locking projection 108 in simple especially mode.
By press surface 110 clamping camber member 104 is especially easily discharged from its locking.The user knows clearly, where he must push in order to take out the sand paper that worn and torn.This is pushed is simple especially, is arranged on the rational position because this press surface meets ergonomics ground and satisfies finger with requiring.
