[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Embodiment one: in the prior art, when assembling multiple cutters into the cutter grooves, the installer has difficulty in controlling the distance of the cutter heads of the cutters extending out of the cutter grooves, which easily causes the distance of the cutter heads to the shaft center of the cutter disc to be different, resulting in the unevenness of the cylindrical surface cut by the cutters on the cutter disc, and reducing the precision of the cylindrical surface cut by the cutters on the cutter disc.

[0023] Therefore, in order to solve the above problems and realize the function of improving the cutter installation precision, the utility model discloses a cutter disc structure for inclined lathing, referring to Figure 1 and Figure 2 , comprising a disc body 1 and a positioning assembly, specifically, a plurality of cutter grooves 4 are formed on the disc body 1, the plurality of cutter grooves 4 extend from the center of the disc body 1 to the edge of the disc body 1, the positioning assembly comprises a positioning block 5 and a supporting plate 7, two supporting plates 7 are respectively arranged on the two inner walls of the cutter groove 4, the two ends of the bottom of the positioning block 5 respectively abut against the top of the two supporting plates 7, wherein the length of the two supporting plates 7 is equal to the length of the cutter groove 4, and a plurality of fixing holes are equidistantly arranged on the top of the two supporting plates 7, and the two ends of the positioning block 5 are respectively provided with a fixing rod 6 matched with the fixing hole.

[0024] In the embodiment, the positioning of the cutter by the installer during the installation of the cutter can be realized by the positioning plate 5, so that the distance of the cutter head of all the cutters to the center of the disc body 1 is equal after being installed into the cutter groove 4, thereby improving the overall assembly speed and precision of the cutter, and the installer does not need to measure the length of the cutter head extending out of one end of the cutter groove 4 during the installation of each cutter.

[0025] In the specific embodiment, before the installation of the cutter, the installer first installs the positioning block 5 in any one cutter groove 4 by inserting the fixing rod 6 into the fixing hole, since the fixing holes on the top of the supporting plate 7 are equidistantly arranged, the user can install the positioning block 5 at the corresponding position in other cutter grooves 4 according to the position of the fixing hole into which the fixing rod 6 is inserted, for example, in the first cutter groove 4, the fixing rod 6 is inserted into the third fixing hole from the edge of the disc body 1, so that in all the subsequent cutter grooves 4, the installer only needs to insert the fixing rod 6 into the third fixing hole from the edge of the disc body 1 at the corresponding position in the first cutter groove 4, so that the distance of the positioning block 5 in all the cutter grooves 4 to the center of the disc body 1 is consistent, and then during the installation of the cutter, the installer can first abut the cutter tail against the positioning block 5, so that the cutter does not move forward after entering the cutter groove 4, and since the positioning block 5 can ensure the consistent distance to the center of the disc body 1 in each cutter groove 4, the distance of the cutter head to the center of the disc body 1 after the installation of the cutter can also be kept the same.

[0026] It should be noted that the fixed hole can be selected as a threaded blind hole, so that the fixing rod 6 can firmly fix the positioning block 5 on the supporting plate 7, so that the positioning block 5 can stably limit the tool.

[0027] In another embodiment, when the distance between the tool head and the tool groove 4 needs to be adjusted, the operator can first rotate the fixing rod 6 out of the corresponding fixed hole, so that the positioning block 5 is disconnected with the supporting plate 7. Then, according to the required adjustment distance, the fixing rod 6 is inserted into other fixed holes. For example, if the tool head needs to be extended by a certain distance, the fixing rod 6 can be moved and inserted into the fixed hole near the edge of the disc body 1; if the tool head needs to be reduced, the fixing rod 6 can be moved and inserted into the fixed hole near the center of the disc body 1.

[0028] After reinserting the fixing rod 6, the positioning block 5 is fixed at the new position, and when the tool is installed again, the tool tail is abutted on the positioning block 5 at the new position, so that the adjustment of the distance between the tool head and the tool groove 4 is realized.

[0029] Further, in order to facilitate the operator to intuitively understand and master the distance between the tool head and the tool groove 4, a scale mark (not shown) can be provided on the surface of the disc body 1. The scale marks are distributed along the direction in which the tool groove 4 extends, and the scale values correspond to the approximate distance of the tool head extending out of the tool groove 4 under different fixed hole positions. In this way, when adjusting the position of the positioning block 5 or installing the tool, the operator only needs to observe the relative position of the tool tail and the scale mark to determine whether the distance of the tool head extending out meets the processing requirements, thereby further improving the convenience and accuracy of the tool installation precision adjustment.

[0030] In the embodiment, the disc body 1 is provided with a central axis 2, and the central axis 2 is circumscribed by a rotating member. The rotating member can be an electric motor, which drives the disc body 1 to rotate.

[0031] Example two: based on example one, in order to improve the moving convenience of the positioning block 5, referring to Figures 1-3 The utility model also includes a sliding groove 9 and a sliding block 8, specifically, the tool groove 4 is provided with a sliding groove 9, and the sliding groove 9 extends along the length direction of the tool groove 4, wherein the positioning block 5 is transversely arranged on the top of the sliding groove 9, and the bottom of the positioning block 5 is provided with a sliding block 8 matched with the sliding groove 9.

[0032] In the embodiment, through the arrangement, the positioning block 5 can smoothly move along the sliding groove 9, and the cooperation between the sliding block 8 and the sliding groove 9 provides a guiding effect for the movement of the positioning block 5, so that the positioning block 5 is more stable and accurate when adjusting the position, effectively avoiding the deviation or shaking of the positioning block 5 during the movement, thereby further improving the reliability of the tool installation precision adjustment.

[0033] Meanwhile, the sliding groove 9 is a dovetail groove, and the sliding block 8 is provided with a pulley 10 abutting against the inner wall of the sliding groove 9. Through the above structure, the design of the dovetail groove can enhance the connection stability between the positioning block 5 and the tool groove 4, and prevent the positioning block 5 from accidentally separating during use. The setting of the pulley 10 greatly reduces the friction between the sliding block 8 and the inner wall of the sliding groove 9, so that the movement of the positioning block 5 is more relaxed and labor-saving, and the operator is more convenient and efficient when adjusting the position of the positioning block 5, especially in the case of frequent adjustment of the tool installation precision, which can significantly improve the work efficiency.

[0034] Further, the inner wall of the sliding groove 9 is provided with a brush, and the brush is in contact with the sliding block 8. This setting makes the brush can clean the dust, debris and other impurities that may be attached to the surface of the sliding block 8 and the inner wall of the sliding groove 9 in time when the sliding block 8 moves in the sliding groove 9, keeps the sliding block 8 and the sliding groove 9 clean, avoids the accumulation of impurities affecting the movement precision of the positioning block 5, and further ensures the stability and reliability of the tool installation precision.

[0035] Example three: on the basis of example one, in order to improve the firmness of the tool, referring to Figure 2 The utility model also includes the fender 3 for clamping tool, specifically, the fender 3 is equipped between two adjacent tool grooves 4, and the length of fender 3 is equal to the length of tool groove 4.

[0036] In this embodiment, the setting of the fender 3 can block the tool from the side after the tool is installed, prevent the tool from lateral displacement due to cutting force and other external forces during processing, and further improve the stability of the tool in the tool groove 4.

[0037] Further, the side of the fender 3 towards the tool groove 4 is provided with a receiving groove 12, and the receiving groove 12 is provided with a clamping assembly. The clamping assembly includes a clamping plate 11 and a spring 13, wherein the fender 3 is arranged at the opening of the receiving groove 12, the fender 3 is matched with the opening of the receiving groove 12, and the spring 13 is connected between the clamping plate 11 and the receiving groove 12. This setting makes the spring 13 push the clamping plate 11 to move towards the tool when the tool is installed in the tool groove 4, so as to tightly clamp the tool in the tool groove 4.

[0038] When installing the tool, the tool is only needed to be placed in the tool groove 4 at a suitable position, and the clamping plate 11 will clamp the tool under the action of the spring 13, which is simple and convenient. Moreover, different sizes of tools can be reliably clamped through the elastic deformation of the spring 13, which improves the compatibility of the cutter structure to different tools.

[0039] Preferably, the clamping plate 11 is provided with a rubber pad on the side away from the spring 13. The rubber pad can increase the friction between the clamping plate 11 and the tool, prevent the tool from slipping during clamping, and further improve the fixing firmness of the tool. At the same time, the rubber pad can also play a buffering role, avoid scratching or damaging the surface of the tool by the clamping plate 11, protect the integrity of the tool, and prolong the service life of the tool.

[0040] In summary, in combination with Embodiment One to Embodiment Three, the working steps of the tool disc structure for inclined machining are as follows: first, before installing the tool, the target interval of the tool bit extending out of the tool groove 4 is determined according to the machining requirements, then the positioning block 5 is installed to the corresponding position in the tool groove 4 through the fixed rod 6 and the fixed hole, and the relative position relationship between the fixed holes is used to ensure that the distance between the positioning block 5 and the center of the disc body 1 meets the tool installation accuracy requirements. Then, the tool tail is abutted on the positioning block 5, and the tool is slid into the appropriate position along the tool groove 4, at this time the clamping assembly on one side of the stop block 3 will clamp the tool, and the installation and fixing of the tool are completed. During the machining process, if it is necessary to adjust the interval of the tool bit extending out of the tool groove 4, the installer can first rotate out the fixed rod 6, move the positioning block 5 to a new position and reinsert the fixed rod 6 to fix, and then reinstall the tool.
