As shown in fig. 1 to 5, the utility model provides a deburring fixture, including installation base member 1 and blade holder 2, wherein blade holder 2 is installed on installation base member 1, be provided with the cutter fixed knot who is used for fixed cutter a on the blade holder 2 and construct, cutter a is located that cutting edge one side is outwards stretched out, and there is a spatial component for the material walking direction is parallel with blade holder 2 in the cutting edge in the space, cutter fixed knot constructs can force the one end incurving perk that cutter a that its was fixed is located relative material walking direction feeding. It should be noted that, in the present application, the tool fixing structure may be a conventional clamping structure, or may be a conventional locking structure, and directly locks or compresses the blade by using a screw. In this application, the material is a plate, especially a plate for manufacturing furniture, and is indicated by reference sign b in fig. 5. The edge sealing material of such sheet materials contains a lot of particulate matter, similar to powder particles, which easily wear the knife during the process of the traditional knife using drive to remove the excess part of the edge sealing. Because the cutting area of the traditional cutter is too concentrated in one place, the cutter is broken in the cutting area. And in this application, because the cutting edge has one in the space and the parallel space component of blade holder 2 for the material walking direction, its cutting edge is the low-angle slope relative banding advancing direction, and the area of contact increase of cutting edge and banding has slowed down the holistic rate of wear of cutter, the live time of extension cutter.

Furthermore, the knife fixing structure is provided with a knife groove 21 on one side of the knife fixing structure relative to the material walking direction, the opening direction of the knife groove 21 is inclined downwards, the knife groove 21 comprises a feeding bent portion 211 and a clamping portion 212, the feeding bent portion 211 is arranged at the front end of the clamping portion 212, the clamping portion 212 is used for clamping a knife a, and the feeding bent portion 211 is outwards tilted relative to the plane where the clamping portion 212 is located, so that the knife a part located in the feeding bent portion 211 is deformed and tilted. It should be noted that the outward tilting means that the feeding bent portion 211 is far away from the plane where the processed plate b is located. In fact, the cutter a fixed by the cutter fixing structure in the application is a deformable blade, and the design enables the cutter a to have certain flexible deformation capacity, so that the contact flexibility of the cutter a and the plate b is improved.

In fig. 1, 2 and 5, the relative material traveling direction is defined as the positive direction of the X axis, upward is the positive direction of the Z axis, and outward is the positive direction of the Y axis. Therefore, the cutter groove 21 is a spatially non-regular positive direction, the length direction of the cutter groove 21 has components in X, Y and Z-axis directions, wherein the included angle between the length direction of the cutter groove 21 and the material walking direction is 10-40 degrees, namely the angle between the length direction of the cutter groove 21 and the X-axis positive direction is 10-40 degrees, and correspondingly, the angle between the length direction of the cutter a clamped in the cutter groove 21 and the X-axis positive direction is 10-40 degrees; the minimum angle of the plane where the opening of the cutter groove 21 is located relative to the horizontal plane is 5-20 degrees, namely the angle of the blade direction of the cutter a clamped in the cutter groove 21 relative to the positive direction of the Y axis is 5-20 degrees. In the present application, the blade of the tool a clamped in the pocket 21 may or may not have a component in the Z-axis direction, and therefore, in the present application, it is preferable that the blade of the tool a clamped in the pocket 21 has no component in the Z-axis direction in practical use, and the present application will not be described in detail. In another embodiment of the present application, an included angle of the knife groove 21 with respect to the Z-axis direction may be 1 to 20 °, that is, in the present application, one end of the knife groove 21 in the discharging direction is inclined upward gradually with respect to one end of the feeding direction, and at the same time, one end of the knife groove 21 in the discharging direction is also inclined gradually toward the opening side direction, such a design enables the blade of the knife a clamped in the knife groove 21 to be spatially closed and have good contact with the plate b along the X-axis forward direction. The design position of the clamping portion 212 in space is basically consistent with that of the clamping portion, the feeding bent portion 211 is tilted upwards relative to the clamping portion 212, the tilting angle of the feeding bent portion relative to the plane where the clamping portion 212 is located is 3-20 degrees, and a tilting amount of 10 degrees is preferably selected, so that the whole feeding bent portion 211 is slightly tilted upwards in the positive direction of the X axis compared with the positive direction of the X axis, and the situation that the bouncing knife is caused due to hard collision with the edge of the plate b which is fed along the positive direction of the X axis is avoided. Referring to fig. 5, in actual use, the position where the cutter a is located at the clamping portion 212 serves as a main area in contact with the plate material b, i.e., the cutter a portion of the area is mainly used for cutting. The cutter a limited in the feeding bent portion 211 is tilted relative to the clamping portion 212, so that the cutter a in the region can press the plate b downwards when contacting the plate b at first, and meanwhile, the cutter a has flexible deformation due to the reaction force of the plate b, so that the included angle formed between the edge sealing part and the edge sealing part of the plate b is reduced, and the contact area of the edge sealing part and the edge sealing part is increased. As the plate material b moves relative to the whole cutter a, the part of the plate material b to be cut enters the clamping part 212, and the surplus part is cut by the blade of the part of the cutter a in the clamping part 212. By the design, when the plate b moves relative to the cutter a, the cutting edge and the sealing edge in the area of the clamping part 212 are always in a cutting state, so that the advancing direction of the cutting edge and the sealing edge which is not cut are always kept at a small angle, and the cutting edge can better cut the flash and the glue on the sealing edge by the design of the small angle.
