Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, the nozzle cutting tool assembly includes a holder 1, and the holder 1 is mounted on a driving mechanism (not shown) and driven by the driving mechanism to move up and down. A cutter 2 is mounted in the cutter holder 1.

As shown in fig. 2, a slide groove i 17 in the vertical direction is opened in the tool holder 1, the slide groove 17 extends vertically and downwardly from the top of the tool holder 1, and the tool 2 slides into a predetermined position from the top to the bottom from the slide groove i 17.

As shown in fig. 5, the back surface 9 of the cutter 2 is provided with a positioning groove 11, as shown in fig. 2, the cutter holder 1 is provided with a positioning pin 12, and the front end of the positioning pin 12 extends into the positioning groove 11, so as to limit the cutter 2 from moving up and down. The front-rear position (left-right position in fig. 2) of the positioning pin 12 is adjustable. The front end of the positioning pin 12 does not abut against the cutter 2, so that a space is reserved for the left and right movement of the cutter 2.

As shown in fig. 2 and 3, the back 9 of the cutter 2 is provided with an elastic mechanism 5, and the elastic mechanism 5 is two spring plungers which are of a structure conventional in the art and are provided with springs i 10. The elastic mechanism 5 is arranged between the tool apron 1 and the tool 2 and is used for tightly abutting against the tool 2. After the cutter 2 contacts the workpiece 19, the cutter 2 contacts the water gap 20 and slightly moves to the left, and the spring I10 moves to the left in the cutter 2 and is compressed to increase the elastic force, so that the cutter 2 is tightly pressed on the water gap 20. The spring force of the spring I10 is adjustable, for example, the spring plunger can be moved back to the left or moved forward to the right.

As shown in fig. 5, the cutting surface 3 of the cutter 2 is provided with a plurality of cutting edges 4, the cutting edges 4 are arranged in sequence in the vertical direction, and the cutting edges 4 are contacted with the water gap 20 on the workpiece 19 in sequence during the downward movement of the cutter 2 along with the cutter holder 1, so that the water gap 20 is cut for a plurality of times, and burrs on the water gap 20 can be removed well.

As shown in fig. 5, the cutting edges 4 are provided with gaps 6 therebetween, the gaps 6 extend away from the cutting surface 3, and inner ends of the gaps 6 are communicated to form cutting grooves 7, and the cutting grooves 7 are used for cutting. The row cutting grooves 7 are opened in the cutter 2, thereby reducing the weight of the cutter 2. The row of cutting flutes 7 extend up and down the tool 2 and through the tool 2 to facilitate removal of the cuts in the row of cutting flutes 7.

As shown in fig. 2, the left side of the knife 2 is still spaced from the left wall of the slide i 17 for the knife 2 to retreat to the left. As shown in fig. 5 and 6, the lower end portion of the slide groove i 17 is a guide groove 8, and the guide groove 8 extends from the front to the rear (from the right to the left in fig. 2). The tool 2 is fitted in the guide groove 8, and the guide groove 8 guides the tool 2 so that the tool 2 can move only in the front-rear direction (left-right direction in fig. 2). I.e. the guide groove 8 guides the movement of the tool 2 in the direction facing away from the cutting surface 3.

As shown in fig. 5 and 6, the guide groove 8 is expanded outward at a set position facing away from the cutting surface 3, and the cutter 2 is correspondingly expanded outward and abuts against the expanded portion of the guide groove 8, thereby restricting the forward movement (rightward movement in fig. 2) of the cutter 2. As shown in fig. 6, the cutting surface 3 does not protrude from the C-surface of the holder 1, the C-surface can be zero-matched with the workpiece 19, the burr on the nozzle 20 is very thin and much smaller than the horizontal width of the single blade 4, the blade 4 cannot contact the workpiece 19 (i.e. the product) due to the blocking of the C-surface, and the blade 4 only contacts the nozzle 20, so that the surface of the workpiece 19 can be protected from being scratched when the burr on the nozzle 20 is cut off.

As shown in fig. 1 and 2, the tool apron 1 is further provided with a sliding groove ii 18. Chute II 18 extends vertically downward. A brake lever 13 is slidably disposed in the sliding groove ii 18. A spring II 14 is arranged at the upper end of the brake rod 13, and when the brake rod 13 slides upwards, the spring II 14 is compressed; spring II 14 expands and contracts to enable brake lever 13 to slide downwards and reset. The lower end of the brake rod 13 extends out of the sliding groove II 18 and is used for abutting against a workpiece 19.

In this example, second chute 18 is in communication with first chute 17, and in other embodiments, second chute 18 may not be in communication with first chute 17.

The side of brake lever 13 is opened with spacing groove 15, and spacing groove 15 extends in the brake lever 13 slip direction. A limit pin 16 is fixed in the tool holder 1, and the front end of the limit pin 16 extends into the limit groove 15. The limit pin 16 is matched with the limit groove 15, so that the brake rod 13 is arranged in the sliding groove II 18 in a sliding mode, and the stroke of the brake rod 13 is limited.

The working principle is as follows:

as shown in fig. 2, the work piece 19 is placed below the brake lever 13, and the brake lever 13 comes into contact with the work piece 19 and stops during the downward movement of the tool rest 1 in the B direction. As shown in fig. 3, the tool holder 1 moves downward, and the brake lever 13 abuts against the workpiece 19 to restrict the movement of the workpiece 19. At this time, the cutter 2 contacts the water gap 20 on the workpiece 19, and the plurality of blades 4 arranged up and down sequentially cut the water gap 20 to cut off burrs on the water gap 20, and the burrs can be effectively removed by cutting the water gap 20 by the blades 4 for a plurality of times because the burr connection is small and has no hardness. Meanwhile, the cutter 2 slightly retreats leftwards due to the fact that the water gap 20 slightly extrudes the cutter 2 leftwards, namely the cutter 2 has a movement amount away from the cutting face 3, and due to the effect of the elastic mechanism 5, the cutter 2 is tightly abutted against the water gap 20 to cut, so that burrs can be cut more thoroughly.

The above embodiments are merely illustrative of the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the content of the present invention and implement the invention, and not to limit the scope of the invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the scope of the present invention.
