DETAILED DESCRIPTION

[0038] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0039] Example:

[0040] like Figure 1-Figure 4 As shown, the radial deep groove machining blade for vertical lathe provided in this embodiment includes a square plate 100, a blade head 200 and an external component 300, wherein:

[0041] The square plate 100 is a rectangular steel plate or iron plate, and its shape is specifically a rectangle, with a length direction and a width direction. The two ends of the square plate 100 in the length direction are defined as the front end and the rear end respectively. A mounting position is provided at the front end of the square plate 100, and the cutter head 200 is installed at the mounting position. The external component 300 is fixedly connected to the square plate 100 and is located near the rear end of the square plate 100. The external component 300 is used to connect with the cutter crown 400 on the machine tool.

[0042] When in use, the machine tool drives the square plate 100 to move through the tool crown 400, and then drives the cutter head 200 to move through the square plate 100. When cutting radial deep grooves, the square plate 100 can extend into the cutting groove, so that the cutter head 200 can extend radially to a deeper position in the workpiece, thereby making the cutting depth deeper, specifically reaching a cutting depth of 600 mm.

[0043] The square plate 100 is provided with an oblique cut 110 and a long cut 120. The oblique cut 110 is located near the front end of the square plate 100, and the long cut 120 extends from the front end of the square plate 100 to the middle of the square plate 100, and the oblique cut 110 and the long cut 120 are respectively located on both sides of the installation position. In this way, the front end of the square plate 100 is more convenient to extend into the cut groove, and the arrangement of the oblique cut 110 and the long cut 120 makes the width of the square plate 100 located behind the cutter head 200 wider, and the oblique cut 110 and the long cut 120 can also release part of the stress inside the square plate 100 during the cutting process, thereby improving the strength of the square plate 100, enhancing the rigidity of the square plate 100, effectively resisting the deformation of the cutter plate caused by the cutting force, reducing the vibration of the cutter head 200 and the square plate 100 during the cutting process, so that the quality of the cut groove obtained by cutting is less. Moreover, the oblique cut 110 and the strip cut 120 can also make the blade material less and lighter. In addition, the strip cut 120 can also be used to discharge the iron chips in the cutting process.

[0044] Optionally, a beveled surface 121 connected to the outer wall of the square plate 100 is provided at the end of the long cut 120, and the beveled surface 121 can further enhance the structural strength and rigidity of the square plate 100, thereby reducing the vibration of the blade during the cutting process. Of course, the end of the long cut 120 can also be a vertical surface perpendicular to the outer wall of the square plate 100.

[0045] An optional implementation of this embodiment is as follows: the above-mentioned installation position is a mounting groove 130 opened on a side plate surface of the square plate 100, the mounting groove 130 passes through the front end of the square plate 100, and the end groove wall of the mounting groove 130 is an arc wall body, and the above-mentioned cutter head 200 is installed in the mounting groove 130. The setting of the mounting groove 130 can further release the internal stress of the square plate 100 during the cutting process and reduce the probability of deformation of the square plate 100 during the cutting process. In order to lock the cutter head 200 in the mounting groove 130, the cutter plate provided in this embodiment also includes a locking member, which is used to lock the cutter head 200 in the mounting groove 130.

[0046] Optionally, the locking member is a locking bolt 500, and a first screw hole 140 communicating with the mounting groove 130 is provided on the side wall of the long cutout 120, and the locking bolt 500 is screwed into the first screw hole 140. When locking, the locking bolt 500 presses against the cutter head 200 located in the mounting groove 130. When installing, first install the cutter head 200 in the mounting groove 130, then screw the locking bolt 500 into the first screw hole 140, and turn the locking bolt 500 so that the locking bolt 500 presses against the cutter head 200 in the mounting groove 130. Since the first screw hole 140 is provided on the side wall of the long cutout 120, it is also helpful to reduce the length of the locking bolt 500.

[0047] In order to make the cutter head 200 more firmly installed in the above-mentioned installation groove 130, in this embodiment, the number of the above-mentioned first screw holes 140 is multiple, and the above-mentioned installation groove 130 extends from the front end of the square plate 100 to the front middle part of the square plate 100, and the length direction of the installation groove 130 is in the same direction as the above-mentioned square plate 100. The multiple first screw holes 140 are evenly distributed along the length direction of the installation groove 130, which is beneficial. The number of the first screw holes 140 is 3 or 4 or 5, and a locking bolt 500 is screwed in each first screw hole 140. In this way, the cutter head 200 is tightened in the above-mentioned installation groove 130 by multiple locking bolts 500, so that the cutter head 200 can be more firmly placed in the installation groove 130.

[0048] More preferably, in this embodiment, one of the above-mentioned mounting positions is provided on both side surfaces of the square plate 100, and the two mounting positions are symmetrically arranged. Correspondingly, the above-mentioned first screw holes 140 and locking bolts 500 are also provided with two groups, and the two mounting positions are respectively used to install different cutter heads 200. In this way, when two cutter heads 200 are installed on the square plate 100 at the same time, the two cutter heads 200 can cut the groove walls on both sides of the groove respectively. In the specific use process, the user can choose to install the cutter head 200 at a mounting position on a certain side according to the situation, or install the cutter head 200 at both mounting positions.

[0049] An optional implementation of this embodiment is as follows: the external component 300 in this embodiment includes a connecting column 310, which is welded and fixed to the square plate 100 or integrally formed, and the connecting column 310 is perpendicular to the plate surface of the square plate 100, and a threaded through hole 311 is provided on the connecting column 310, and a connecting bolt 600 is screwed into the threaded through hole 311, and a second screw hole is provided on the outer wall of the knife crown 400 of the machine tool, and the above-mentioned connecting bolt 600 is also screwed into the second screw hole, so that the connecting column 310 is connected to the knife crown 400 of the machine tool, and then the entire knife plate is connected to the knife crown 400 of the machine tool. It should be noted that in order to ensure that the cutting plane passes through the rotation center of the machine tool during turning, the upper plane of the above-mentioned mounting groove 130 (the upper plane is flush with the cutting plane of the cutter head 200) needs to be coplanar with the X-axis of the machine tool and pass through the rotation center of the machine tool.

[0050] More preferably, the external component 300 also includes an auxiliary column 320, which is fixed to the square plate 100 and is located on the same side of the square plate 100 as the connecting column 310, the auxiliary column 320 is perpendicular to the plate surface of the square plate 100, and a first notch and a second notch are respectively opened in the middle of the two opposite outer walls of the above-mentioned knife crown 400, the above-mentioned second screw hole is opened on the side wall of the first notch, the above-mentioned connecting column 310 is placed in the above-mentioned first notch, and the auxiliary column 320 is placed in the second notch, and the outer wall of the connecting column 310 is in contact with the side wall of the first notch, and the outer wall of the auxiliary column 320 is in contact with the side wall of the second notch. In this way, the external component 300 and the knife crown 400 are connected more closely, thereby enhancing the installation and fixing rigidity of the knife plate on the knife crown 400, further expanding the contact area between the knife crown 400 and the external component 300, and thereby reducing the vibration of the knife head 200 and the knife plate during the cutting process.

[0051] In order to further increase the connection rigidity between the external component 300 and the blade crown 400, optionally, in the present embodiment, the external component 300 further includes an intermediate column 330 connected between the connecting column 310 and the auxiliary column 320, and the intermediate column 330 is parallel to the plate surface of the square plate 100. A third notch connecting the first notch and the second notch is further provided on the outer wall of the blade crown 400. The intermediate column 330 is placed in the third notch, and the outer wall of the intermediate column 330 is in contact with the side wall of the third notch. In this way, the contact area between the blade crown 400 and the external component 300 can be further expanded, thereby reducing the vibration of the cutter head 200 and the blade during the cutting process.

[0052] In order to further increase the connection rigidity between the external component 300 and the blade crown 400, optionally, in the present embodiment, a square groove 150 is opened on one side plate surface of the blade plate, and the square groove 150 is adapted to the above-mentioned blade crown 400. The square groove 150 passes through the rear end and one side outer wall of the above-mentioned square plate 100. The above-mentioned connecting column 310, auxiliary column 320 and intermediate column 330 are all fixedly connected to the bottom of the square groove 150, and the outer wall of the auxiliary column 320 is connected to one side groove wall of the square groove 150. The above-mentioned blade crown 400 is inserted into the above-mentioned square groove 150 and is attached to the bottom and groove wall of the square groove 150. In this way, the contact area between the blade crown 400 and the external component 300 can be further expanded, thereby reducing the vibration of the blade head 200 and the blade plate during the cutting process.

[0053] By providing the connection column 310, the auxiliary column 320, the intermediate column 330 and the square groove 150, the blade plate can be more stably mounted on the blade crown 400, and the contact area with the blade crown 400 is larger, which is more conducive to enhancing the installation rigidity of the blade plate on the blade crown 400 and reducing the vibration of the cutter head 200 and the blade plate during the cutting process. In order to further enhance the connection rigidity between the blade crown 400 and the external component 300, in this embodiment, a threaded through hole is provided on the side wall of the blade crown 400, and a clamping bolt is screwed into the threaded through hole 400, and the clamping bolt is clamped on the outer wall of the external component 300.

[0054] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
