Description
Technical field
This utility model relates to frock clamp field, more specifically, it relates to a kind of clamping device.
Background technology
The service life of spectacle-frame, eye is extended in order to make the earpiece of spectacle-frame in use can further bend
Mirror foot is made up of earpiece working of plastics and earpiece contact pin, it will usually earpiece working of plastics is inserted into an earpiece contact pin,
Earpiece is glasses important component parts, and earpiece was typically passed through polishing, polishing mainly eye before assembling of spraying paint
Phase mutual friction between mirror foot and grinding abrasive disk, removes the burr on earpiece surface so that earpiece smooth outer surface is convenient
The process sprayed paint, in polishing process, needs often to change grinding abrasive disk, owing to grinding abrasive disk is by installing axle and rotary sleeve
Being connected, then fixedly mount axle by screw through rotary sleeve, this clamping efficiency is low, and the reliability after grinding abrasive disk installation is relatively
Low, operation labor intensity is big.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of clamping device, it is simple to operation,
Clamping efficiency is high.
For achieving the above object, this utility model provides following technical scheme:
A kind of clamping device, including fixed cover and the rotary sleeve that is placed in fixed cover, rotary sleeve is relative with fixed cover energy
Rotate, also include that drawing bar and expansion sleeve, described drawing bar are placed in rotary sleeve；One end of described drawing bar is defeated with driver
Shaft is connected, and the described other end of drawing bar is connected with the rearward end of expansion sleeve；Described expansion sleeve offers many vertically
Bar dilatation joint, the leading section of described expansion sleeve is taper, and the lateral wall of its miner diameter end is convexly equipped with contraction flow region, the medial wall of rotary sleeve
Forming draw-in groove to depression, described contraction flow region is placed in draw-in groove；When the output shaft of driver order about drawing bar be moved rearwards by time, drawing
Bar thus drive dilatation joint contraction flow region depart from draw-in groove, the leading section of described expansion sleeve by rotary sleeve medial wall extrude shrinks.
This utility model is arranged further: the medial wall of described rotary sleeve is convexly equipped with contact part, and described drawing bar is arranged with
Elastic component, one end of described elastic component and contact part conflict, other end back-up ring fixed with drawing bar is inconsistent.
This utility model is arranged further: the outward-dipping setting of described contraction flow region.
This utility model beneficial effect: when the one end installing axle of grinding abrasive disk is placed in the leading section of expansion sleeve, now
The output shaft of driver orders about drawing bar when being moved rearwards by, drawing bar thus drive the contraction flow region of dilatation joint to depart from draw-in groove, described
The leading section of expansion sleeve is extruded by the medial wall of rotary sleeve shrinks, and the leading section of described expansion sleeve can clamp installation axle so that swollen
Expansion set with install axle compact siro spinning technology again together with, when disassembly is desired, the output shaft of driver orders about drawing bar and moves forward, drawing
Bar thus drive the contraction flow region of dilatation joint to be replaced in draw-in groove, the leading section of expansion sleeve can unclamp installation axle realize dismounting, just
In grinding abrasive disk dismounting and installation, improve clamping efficiency.

Detailed description of the invention
This utility model one clamping device is described in further details by 1 to Fig. 3 referring to the drawings.
A kind of clamping device, including fixed cover 1 and the rotary sleeve 2 that is placed in fixed cover 1, rotary sleeve 2 by bearing with
Fixed cover 1 relatively rotates, and also includes that drawing bar 3 and expansion sleeve 4, described drawing bar 3 are placed in rotary sleeve 2；Described drawing bar 3
One end is connected with the output shaft of driver 5, and the other end of described drawing bar 3 is connected with the rearward end of expansion sleeve 4；Described swollen
Expansion set 4 offers a plurality of dilatation joint vertically, and the leading section of described expansion sleeve 4 is taper, and the lateral wall of its miner diameter end is convexly equipped with
Contraction flow region 41, the medial wall of rotary sleeve 2 forms draw-in groove 21 to depression, and described contraction flow region 41 is placed in draw-in groove 21；When driver 5
Output shaft orders about drawing bar 3 when being moved rearwards by, drawing bar 3 thus drive the contraction flow region 41 of dilatation joint to depart from draw-in groove 21, described swollen
The leading section of expansion set 4 is extruded by the medial wall of rotary sleeve 2 shrinks.
The medial wall of described rotary sleeve 2 is convexly equipped with contact part 22, and described drawing bar 3 is arranged with elastic component 6, described elastic component
Conflicting with contact part 22 in one end of 6, other end back-up ring fixed with drawing bar 3 is inconsistent so that elastic component 6 is to drawing bar 3 all the time
It is moved rearwards by pretightning force, it is to avoid expansion sleeve 4 clamping is accidentally unlocked when installing axle, improves its installation reliability.
The wherein said outward-dipping setting of contraction flow region 41, it is simple to contraction flow region 41 departs from draw-in groove 21.
Operation principle: when the one end installing axle of grinding abrasive disk is placed in the leading section of expansion sleeve 4, now driver 5
Output shaft orders about drawing bar 3 when being moved rearwards by, drawing bar 3 thus drive the contraction flow region 41 of dilatation joint to depart from draw-in groove 21, described swollen
The leading section of expansion set 4 is extruded by the medial wall of rotary sleeve 2 shrinks, and the leading section of described expansion sleeve 4 can clamp installation axle so that swollen
Expansion set 4 with install axle compact siro spinning technology again together with, when disassembly is desired, the output shaft of driver 5 orders about drawing bar 3 and moves forward,
Drawing bar 3 thus drive the contraction flow region 41 of dilatation joint to be replaced in draw-in groove 21, it is real that installation axle can be unclamped in the leading section of expansion sleeve 4
Now dismantle, it is simple to grinding abrasive disk dismounting and installation, improve clamping efficiency.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, without departing from the some improvement under this utility model principle premise and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
