Abstract

A device which prevents a compound saw from cutting table top inclination includes a positioning plate which is arranged on the rocker framework axis pin of the compound saw and rotates around the axis pin, a bearing which is fixed with the skew table top board of the compound saw into one whole and is provided with a limit slot relative to the lower end of the positioning plate, a top plate which is fixed on the bottom of the skew table top of the compound saw and the lower end of the top plate contacts with the upper end of the positioning plate and the top plate when moving downward drives the positioning plate to rotate and cause the lower end to be embedded in the limit slot of the bearing, and a spring which forces the lower end of the positioning plate to be away from the limit slot of the bearing. After the utility model is used, when the compound sawing is in the skew state, the lower end of the positioning plate is away from the limit slot of the bearing and does not affect the normal lateral rotation of the rocker, but when the compound sawing changes to the cutting state, the top plate moves downward with the cutting table top to drive the positioning plate to rotate and cause the lower end to be embedded in limit slot of the bearing, and thus lateral rotation of the rocker relative to the cutting table top is restricted, thereby preventing cutting the table top inclination. The utility model has simple and reliable structure and is very suitable for the transformation of the prior products.

Description

A kind ofly prevent that compound saw from cutting the device that table top tilts at platform during cutting on table

Technical field

The utility model relates to a kind of Tai Qie of having concurrently and the compound saw of two kinds of mode of operations of cutting sth. askew, and particularly a kind ofly prevents that compound saw from cutting the device that table top tilts at platform during cutting on table

Background technology

Compound saw is a kind of desk type electric tools that bias cutter and bench saw are united two into one, designing requirement according to bias cutter, saw blade relatively vertically mode is done 45 ° of inclinations, for compound saw, just its cut is made the table top work top of can cutting sth. askew relatively and is done 45 ° of inclinations, according to existing compound saw structure, when being transformed into platform and cutting state, this function can't be eliminated.Yet new bench saw standard (standard No. is PREN61029-1-2) regulation according to calendar year 2001, compound saw is when platform is cut state, and the worktable panel of bench saw does not allow, therefore, must be improved original compound saw structure, could be adapted to the requirement of this new standard.

Summary of the invention

Technical problem to be solved in the utility model is exactly to provide a kind of to prevent that compound saw from cutting the device that table top tilts at platform during cutting on table at above-mentioned prior art present situation

The utility model solves the problems of the technologies described above the technical scheme that is adopted: can prevent that compound saw from cutting the device that table top tilts at platform during cutting on table and including

One is arranged on the rocking bar framework bearing pin of compound saw and can be around the spacer of its rotation;

One bearing that is fixed as one with the deck plate of cutting sth. askew of compound saw, it is provided with a stopper slot relative with the spacer lower end;

One is fixed on the top flat on the platform tangent plane plate bottom of compound saw, and its lower end contacts with the upper end of spacer, and drives when it moves down in the stopper slot that the spacer rotation makes its lower end embedding bearing;

And one force the spring of spacer lower end away from the bearing stopper slot.

Described spacer can directly be sleeved on the rocking bar framework bearing pin of compound saw, and its upper end can be ramped shaped at the opposite position with the top flat lower end; Described spring one end can be fixed on the middle part of spacer, and the other end then is fixed on the rocking bar, for making spacer more stable status is arranged under the state of cutting sth. askew, and a projection that stretches into the rocking bar locating slot can be set in the middle.

After using the utility model, when compound saw is in when cutting sth. askew state, the stopper slot of bearing is left in the lower end of spacer, the normal side that does not influence its rocking bar is changeed, and when compound saw was transformed into platform and cuts state, top flat was cut table top with platform and is moved down, and drove the spacer rotation and made its lower end embed the stopper slot of bearing, therefore cut sth. askew the relatively side of table top of rocking bar is changeed and is limited, and stops platform to cut the purpose that table top tilts thereby reach.Of the present utility model simple and reliable for structure, do not change original compound saw structure again, therefore very suitable transformation to existing product.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 6, can prevent that compound saw from cutting the device that table top tilts at platform during cutting on table and including:

One is sleeved on the rocking bar framework bearing pin 5 of compound saw and can be around the spacer 3 of its rotation, and its middle part is provided with a projection 31 that stretches into the rocking bar locating slot;

One bearing 7 that is fixed as one with the deck plate 8 of cutting sth. askew of compound saw, it is provided with a stopper slot 71 relative with spacer 3 lower ends;

One is fixed on the top flat 2 on platform tangent plane plate 1 bottom of compound saw, and its lower end contacts with the place, slope, upper end of spacer 3, when top flat 2 moves down, promptly drives spacer 3 rotations its lower end is embedded in the stopper slot 71 of bearing;

And one force the spring 4 of spacer 3 lower ends away from the bearing stopper slot, and the one end is fixed on the middle part of spacer 3, and the other end then is fixed on the rocking bar 6.

Cutting state when compound saw from platform is converted to when cutting sth. askew state, top flat 2 is cut on the table top 1 with platform and is moved, the upper end of spacer 3 is left in its lower end, spacer 3 is under the pulling force effect of spring 4, clockwise rotate until the projection 31 at its middle part spacing by the end of rocking bar locating slot 71, this moment, its lower end broke away from the stopper slot 71 on bearing 7, so rocking bar 6 table top 8 sides of can cutting sth. askew relatively change, thereby can make saw blade inclination 45;

When compound saw when the state of cutting sth. askew is transformed into platform and cuts state, fuselage is depressed to locking, make fuselage keep substantially parallel with the table top 8 of cutting sth. askew, loosen this moment locking button that platform cuts deck plate 1 with platform cut table top 1 around its bearing pin rotation depress and with fuselage maintenance level, so top flat 2 is cut table top 1 with platform and is moved down, driving spacer 3 is rotated counterclockwise, force its lower end to embed in the stopper slot 71 of bearing 7, therefore cut sth. askew the relatively side of table top 8 of rocking bar 6 is changeed and is limited, and stops platform to cut the purpose that table top 1 tilts thereby reach.
