Description

Riving knife adjuster for sawing machine

Technical field

The present invention is relevant with saw cutting implement, refers to especially a kind of Riving knife adjuster for sawing machine of for convenience detach and stabilized structure.

Background technology

For fear of being affected improper clamping saw blade by the workpiece of sawing part because being subject to the back stretch of lasting thrust and material own; saw cutting implement can arrange a chopper conventionally; allow chopper incision workpiece by the joint-cutting being produced after saw blade sawing; in order to strut workpiece by the part of sawing, and then assist operator is safer and push effortlessly workpiece.

Yet, traditional chopper is all to use the mode of bolt locking to be fixed, but chopper often need to coordinate the difference of processing content and change, and existing design not only causes the difficulty of chopper dismounting, the locating effect that simultaneously offers chopper is also quite limited, therefore there is necessity of improvement.

Summary of the invention

Main purpose of the present invention is to provide a kind of Riving knife adjuster for sawing machine, and it can conveniently complete the dismounting of chopper, can allow chopper obtain good locating effect simultaneously.

In order to reach above-mentioned purpose, Riving knife adjuster for sawing machine of the present invention includes a chopper seat, a chopper, an elastic component, and a fixture.This chopper seat has a long slot bore; This chopper has an elongated slot and at least one breach, and this breach is formed by the cell wall depression of this elongated slot; This elastic component is located at this chopper seat; This fixture is arranged in the elongated slot of this chopper and the long slot bore of this chopper seat and this chopper is fixed on to this chopper seat, can be subject to the contact of this elastic component and be sticked in the breach of this chopper, so that the locating effect that this chopper is good to be provided.

By above-mentioned design, operator is as long as the application of force overcomes the elastic force that this elastic component is bestowed this fixture, allow this fixture depart from the breach of this chopper and be positioned at the elongated slot of this chopper, just this chopper being disassembled along the elongated slot of this chopper, to reach object for convenience detach.

The specific embodiment

In order to describe structure of the present invention, feature and effect place in detail, hereby enumerate a preferred embodiment and coordinate following graphic explanation as after.

Referring to Fig. 1 to Fig. 2, is the Riving knife adjuster for sawing machine 10 that a preferred embodiment of the present invention provides, and includes a chopper seat 20, a fixed head 30, a chopper 40, one first elastic component 50, and a retaining element 60.

Chopper seat 20 has a fixed part 22, and the central authorities of fixed part 22 have one first long slot bore 24, and chopper seat 20 is respectively equipped with one first backstay 26 in the upper and lower of the first long slot bore 24, and in the lower right of fixed part 22, is provided with one second backstay 28.

Fixed head 30 is installed on the first backstay 26 of chopper seat 20, and has the second long slot bore 32 of corresponding first long slot bore 24.

Chopper 40 has an elongated slot 42, can wear for the first backstay 26 of chopper seat 20, allows chopper 40 between chopper seat 20 and fixed head 30 and energy phase broadsword v.broadsword seat 20 moves up and down, and is reliably butted on the second backstay 28; In addition, chopper 40 has two breach 44, and this two breach 44 is formed by the cell wall depression of elongated slot 42, and is close to respectively two ends at the bottom of the top of elongated slot 42 and is set in distance in the same side of elongated slot 42.

The first elastic component 50 is fixed on chopper seat 20 by a bolt 52 that is locked in chopper seat 20, and is positioned at the rear of the fixed part 22 of chopper seat 20.

Refer to Fig. 2 to Fig. 3, retaining element 60 has a fixture 61, a clamp holder 62, leader 63, a plug member 64, and one second elastic component 65.Fixture 61 is sequentially through the second long slot bore 32 of fixed head 30, the elongated slot 42 of chopper 40, and the first long slot bore 24 of chopper seat 20, and is bolted with a fixed block 66 for the first elastic component 50 ejections, be sheathed on fixture 61 clamp holder 62 close-fittings, and there is one first tooth portion 622 in outer peripheral face, handle 63 is sheathed on the head end of fixture 61, and there is one second tooth portion 632 and a flange 634 in abutting connection with the second tooth portion 632 in inner peripheral surface, can axially moving between P1Yu Yi separation point position, a position of engagement P2 along fixture 61, when handle 63 is positioned at position of engagement P1, as shown in Figure 3, the second tooth portion 632 of handle 63 is intermeshing with the first tooth portion 622 of clamp holder 62, making handle 63 can see through clamp holder 62 drives fixture 61 to rotate, when handle 63 is positioned at separation point position P2, as shown in Figure 4, the second tooth portion 632 and the first tooth portion 622 of clamp holder 62 of handle 63 are separated from each other, handle 63 can freely be rotated relative to fixture 61, plug member 64 is sheathed on the head end of fixture 61 and is positioned at handle 63, the second elastic component 65 is located between the flange 634 and plug member 64 of handle 63, to provide elastic force that handle 63 is remained on to position of engagement P1.

When operator will locate chopper 40, first along the elongated slot 42 of chopper 40, adjust the position of chopper 40, as shown in Figure 5, until fixture 61 is during over against the wherein breach 44 of chopper 40, the fixed block 66 that is bolted in fixture 61 just can be subject to allowing fixture 61 produce lateral displacements from the contact effect of the first elastic component 50, use in the breach 44 that is sticked in chopper 40, as shown in Figure 6, follow operator's swing handle 63 again, handle 63 is seen through and clamp holder 62 between meshing relation and interlock fixture 61 rotates, fixture 61 can see through and towards chopper 40, move gradually with the relation that is spirally connected of fixed block 66 again, allow clamp holder 62 see through ejection one packing ring 67 and chopper 40 is packed between chopper seat 20 and fixed head 30, the location that so just completes chopper 40, as shown in Figure 3.

When operator will dismantle chopper 40, first rotate backward handle 63, to unscrew the relation that is spirally connected between fixture 61 and fixed block 66, and allow clamp holder 62 discharge the packing strength of bestowing chopper 40, then the application of force overcomes the elastic force that the first elastic component 50 is bestowed fixed block 66 again, allow fixture 61 move in the elongated slot 42 of chopper 40 from the breach 44 of chopper 40, operator just can disassemble chopper 40 along the elongated slot 42 of chopper 40.

On the other hand, in order to facilitate swing handle 63 and to avoid handle 63 and other member to interfere with each other, operator can the application of force pull out handle 63 to separation point position P2 from position of engagement P1, as shown in Figure 4, now, just after handle 63 being turned to suitable position, discharge again the pulling force of bestowing handle 63, allow handle 63 return position of engagement P1, to drive fixture 61 rotations.

Comprehensive the above, Riving knife adjuster for sawing machine of the present invention not only can provide the locating effect that chopper is good, also can easily chopper be disassembled, really to reach object of the present invention simultaneously.

The present invention takes off disclosed composed component in embodiment in front, only for illustrating, is not used for limiting the scope of the invention, and substituting or changing of other equivalence element, also should be claim scope of the present invention and contain.
