Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The specific embodiment of the utility model provides a group cutting table, which comprises a sliding table 1, a sliding block 2 connected with the sliding table 1 in a sliding way, a saw blade 3, a spacer 4 and a backer; the sliding table 1 is used for realizing the effects of installing saw blades and realizing the sliding of wood, a backer is arranged on the sliding block 2 by arranging the sliding block 2 to be matched with the sliding table 1 for use, then the wood is pressed close to the backer, the backer is pushed to move so as to drive the wood to move, the cutting of the wood by the saw blades 3 is completed in the moving process, and the backer is used for being matched with different woods to be cut into different shapes, angles, grooves and the like; the backer can be dismantled with slider 2 and be connected, and the backer can be for frame angle backer 8 or parquet angle backer 16 simultaneously, when adopting different backer to set up on slider 2, places timber again after the different preset position of slider 2 with the backer installation simultaneously and cuts.

The two saw blades 3 are arranged in parallel, as shown in figure 9, a clamping groove with a fixed width on the wood can be directly formed by the arrangement of the two saw blades, the spacer 4 is positioned between the two saw blades 3, and as shown in figure 7, the width of the clamping groove on the wood can be adjusted by replacing different spacers 4; the saw blade 3 can be arranged into one, so that the simple cutting of the wood can be realized; in order to realize the replacement of the spacer 4 and the installation of the saw blade 3, the sliding table 1 may include a sliding groove portion 5 and a pressing block 6, the saw blade 3 and the spacer 4 are clamped between the sliding table 1 and the sliding groove portion 5 through a split design of the sliding table 1 as shown in fig. 1-3, the saw blade 3 and the spacer 4 are arranged between the pressing block 6 and the sliding groove portion 5, the saw blade 3, the spacer 4, the saw blade 3 and the pressing block 6 are sequentially arranged from left to right as shown in fig. 1, and the sliding groove portion 5 and the pressing block 6 are connected through bolts, so that various types of installation of a single saw blade, a double saw blade and the like can; specifically, the detachable connection can be realized by adopting the hand-screwed screw rod 22 and the hand-screwed nut 23, the hand-screwed screw rod 22 and the hand-screwed nut 23 can be operated by hands, the arrangement is more convenient for replacing the spacer 4 and installing the saw blade 3, and therefore, a through hole 21 penetrating through the side walls of the sliding groove part 5 and the pressing block 6 needs to be arranged on the sliding table 1, and the through hole is shown in the attached drawing 4; this structure requires the provision of the spacer 4 having a through hole corresponding to the through hole 21, as shown in fig. 13; meanwhile, the saw blade 3 also needs to be provided with two mounting grooves 24 which are matched with the hand-screwed screw 22, as shown in fig. 9, the depth direction of the mounting groove 24 close to the first strip-shaped hole is vertical to the length direction of the saw blade 3, and the mounting groove 24 is arranged on one side far away from the saw teeth of the saw blade 3 and is a vertical mounting groove; the depth direction of the other mounting groove 24 far away from the first strip-shaped hole is consistent with the length direction of the saw blade 3 and is a horizontal mounting groove; on it vertical mounting groove can set up on the screw rod 22 is twisted to the hand in the middle of spout portion 5 and compact heap 6 gap, need earlier spout portion 5 when the installation, compact heap 6 and spacer 4 are twisted screw rod 22 through the hand and are worn to establish, then twist screw rod 22 with the horizontal mounting groove joint of saw bit 3 on one of them hand, then vertical mounting groove sets up on screw rod 22 is twisted to another hand, then twist screw rod 22 and hand screw nut 23 tightening the hand, support saw bit 3 tightly, accomplish the installation.

Through-hole 21 is two, can guarantee the stability of front and back installation still not to the excessive installation of quantity complicated, in order to realize that saw bit 3 exposes the regulation of the height of 1 up end of slip table, consequently need set up one of them through-hole 21 into first bar hole, and the length direction perpendicular to spout 7's length direction in this first bar hole, as shown in figure 2, hand is twisted screw rod 22 and can be adjusted at first bar downthehole, carry out the bolt about (for slip table 1 up-down terminal surface) the regulation so that can realize saw bit 3 and expose the regulation of height, indirect alright realize the regulation to the depth of cut. The height of the saw blade 3 is adjusted, in the technical scheme provided by the application, only one hand-screwed screw rod 22 at a single first strip-shaped hole is adopted for adjustment, so that one end is higher and the other end is lower, the adjustment can be realized in a mode of the vertical mounting groove and the horizontal mounting groove, and as most of the adjustment is carried out by finely adjusting the slightly inclined saw blade 3, the wood can be moved from the lower saw blade 3 to the higher saw blade 3 for cutting, and the process is more consistent with the cutting process; in addition, the two through holes 21 can be set into an adjustable first strip-shaped hole form, so that the heights of the saw blades at the front end and the rear end can be adjusted simultaneously.

It is worth explaining that, the setting of first bar hole can probably make and take place the dislocation between spout portion 5 and the compact heap 6, consequently can also set up the blind hole in one side of through-hole 21 and on the both sides wall that spout portion 5 is relative with compact heap 6, wear to establish the locating pin in the blind hole inside to this realizes the location of spout portion 5 and compact heap 6, the blind hole can set up to the problem that the dislocation about spout portion 5 and compact heap 6 take place for the multiunit further avoids simultaneously.

The slide groove part 5 is detachably connected with the pressing block 6. The sliding groove 7 can be arranged into a dovetail groove, the side wall of the corresponding sliding block 2 is provided with a step shape, the sliding block 2 is limited to move perpendicular to the length direction relative to the sliding groove 7 through the structure, the sliding block 2 can freely slide in the sliding groove 7, and it is worth explaining that the length direction of the saw blade 3 is parallel to the length direction of the sliding groove 7, so that the sliding block 2 drives the wood to normally cut on the saw blade 3 when sliding in the sliding groove 7, and the wood cannot be normally cut if the sliding block 2 is not arranged in parallel and can be driven to move towards one side; the preferred scheme is that the height of slider 2 equals the degree of depth of spout 7, and the up end of slider 2 and the up end parallel and level of spout portion 5 when installing slider 2 inside spout 7 can guarantee freely sliding when setting up on slider 2 for the backer.

The utility model discloses the backer that the embodiment provided includes frame angle backer 8 and parquet angle backer 16 to accomplish the cutting to frame and parquet respectively.

The frame angle rest 8 is of a plate body structure with a bevel edge, the bevel edge has a certain angle, the specific length direction of the bevel edge and the length direction of the sliding groove 7 can form a 60-degree included angle, wood with a 60-degree angle or a 120-degree angle can be cut when the wood leans against the bevel edge for cutting, the frame angle rest 8 is preferably provided with a pair of right-angle edges, and the frame angle rest 8 can be designed into end faces with inner angles of 30 degrees, 60 degrees and 90 degrees respectively, and the end faces are of triangular plate body structures; the length direction of one of the right-angle sides can be perpendicular to the length direction of the sliding groove 7, and the wood can be cut by 90 degrees in such a mode.
