A kind of semi-automatic mill chain device
Technical field:
The present invention relates to a kind of saw chain to chain saw carries out the instrument of grinding, more particularly to a kind of semi-automatic mill chain device,
Its achievable fast accurate positions the function of chain and Automatic-clamping chain.
Background technology:
At work, its chain cutting edge can affect cutting speed and quality because wearing and tearing and rust to chain saw.Need for this into
The grinding of row chain saw carrys out sharpening cutting edge.At present the method for saw chain grinding is had following several:
Cut processing using round file knife hand file, uniformity of the angle of filing, the precision of cutting edge and each cutter head etc. is all difficult to protect
Card, and work efficiency is very low.
Widely used electric chain saw knife sharpener in machinery industry, its grinding saw chain cutting edge grinds chain speed soon more by hand, efficiency
High.But there is also problem:Every one cutting edge of grinding will by two hands to the positioning of chain cutting edge it is impossible to fast accurate
Realization positioning;Every one cutting edge of grinding will be clamped to chain manually, can be to chain grinding edge it is impossible to automatic press from both sides
Tight chain, affects operating efficiency, brings great trouble to operating personnel simultaneously.Therefore, it is necessary to be improved.
Content of the invention:
Present invention aim to overcome that above-mentioned the deficiencies in the prior art, provide a kind of reasonable in design, high working efficiency
And enable the semi-automatic mill chain device that fast accurate positions chain and Automatic-clamping chain.
For achieving the above object, present invention employs following technical scheme:
A kind of semi-automatic mill chain device, including base, described base side is provided with grinding attachment, described base opposite side peace
Equipped with sending chain seat, described send chain seat to be provided with chain guide and limited block, chain is placed on described chain guide, described limited block
Side is provided with limited block adjusting knob, and described sending is additionally provided with the chain positioning dress positioning described chain for fast accurate on chain seat
Put, described base is additionally provided with the chain clamping device for chain described in Automatic-clamping.
Described chain alignment includes front plate, rear plate, regulating bolt and torsion spring, outside described front plate and rear plate
Be respectively provided with a guide plate, described front plate and rear plate side by side in described chain guide, the end of thread of described regulating bolt
Sequentially pass through described front plate and rear plate, described one end is connected with described regulating bolt, the other end and described guide plate
Connect.
Regulation spring is arranged with described regulating bolt.
The inner side of described front plate and rear plate is disposed as ramp structure.
Described chain clamping device includes fixed charge method end plate, movable end plate, jacking block, jackshaft and cam, described fixed charge method end plate
Send on chain seat described in being fixed on, described activity end plate is connected with described jacking block, and described jackshaft one end is connected with described jacking block, separately
One end and described cam engagement, described cam is linked together with the rotating shaft of described grinding attachment.
Described jackshaft and described cam engagement end are movably equipped with a roller, described roller and described cam engagement.
It is additionally provided with set screw between described jacking block and described jackshaft.
Also intermediate shaft supporting bracket is set, described jackshaft is arranged on described intermediate shaft supporting bracket on described base.
Described jackshaft is provided with a flat mouth, described flat mouth with described intermediate shaft supporting bracket cooperation so that described jackshaft only
Can move left and right and can not rotate.
The present invention has the advantage that with respect to prior art:
1st, the present invention, due to being additionally arranged chain alignment, does not need during grinding by two hands, chain cutting edge to be determined
It is only necessary to chain is pulled by a hand to a direction, chain can produce damping with the clamping plate on dynamic positioning system, due to resistance for position
The effect of Buddhist nun makes the torsion spring on positioner that elastic deformation occurs, and after revocation pulling force, torsion spring resilience is driven by forward and backward clamping plate
Chain moves in the opposite direction, moves to opposite direction and can encounter limited block at the sharpening positioning on chain during certain size
On, chain is stop motion, realizes the fast accurate positioning to chain cutting edge.
2nd, the present invention is disposed as ramp structure due to the inner side of front plate and rear plate, can achieve the chain to all size
Bar is clamped, and clamping force size is realized by regulating bolt compression adjustment spring, there is not limitation, applied widely.
3rd, the present invention, due to being additionally arranged chain clamping device, does not need during grinding manually chain to be clamped, work
When making, cam is rotated around pivot together with grinding attachment, and cam promotes jackshaft to move, the mobile drive jacking block of jackshaft
Mobile, jacking block promotion activity end plate moves so that the gap between fixed charge method end plate and movable end plate diminishes to fixed charge method end plate, thus
Realize the clamping to chain.
4th, reasonable in design, operation is very easy, quick, simplifies job step, substantially increases operating efficiency.

Specific embodiment:
Referring to Fig. 1 to Fig. 5, one kind semi-automatic mill chain device providing according to the present invention, including base 1, base 1 side is installed
There is grinding attachment 2, base 1 opposite side is provided with and send chain seat 3, send chain seat 3 to be provided with chain guide 4 and limited block 5, chain 6 is put
On chain guide 4, limited block 5 side is provided with limited block adjusting knob 7, send and is additionally provided with chain seat 3 for fast accurate positioning
The chain alignment 8 of described chain 6, base 1 is provided with the chain clamping device 9 for chain described in Automatic-clamping 6.
Chain alignment 8 includes front plate 81, rear plate 82, regulating bolt 83 and torsion spring 84, front plate 81 and rear folder
Be respectively provided with a guide plate 85 outside plate 82, front plate 81 and rear plate 82 side by side in chain guide 4, the screw thread of regulating bolt 83
End sequentially passes through front plate 81 and rear plate 82, and torsion spring 84 one end is connected with regulating bolt 83, and the other end is connected with guide plate 85.
The positioning it is only necessary to chain 6 is applied with the pulling force in an A direction, chain 6 to chain cutting edge by two hands is not needed during grinding
Damping can be produced with the front plate 81 on dynamic positioning system 8 and rear plate 82, the effect due to damping makes on positioner 8
There is elastic deformation in torsion spring 84, after the pulling force of revocation A direction, front plate 81 is passed through in torsion spring 84 resilience and rear plate 82 produces damping
