Description

Technical Field

[0001] This utility model relates to an alloy cutting tool, specifically a superhard alloy indexable cutting tool with heat dissipation micropores, belonging to the field of alloy cutting tool technology. Background Technology

[0002] In the field of modern machining, especially in the metal cutting industry, the performance of cutting tools directly determines the machining efficiency, accuracy and cost. As the manufacturing industry develops towards high speed, high precision and automation, traditional welded cutting tools are gradually being replaced by indexable inserts due to their limitations such as short life and frequent tool changes. Superhard alloy indexable inserts have become the core solution due to their high hardness, wear resistance and high temperature resistance, and are suitable for heavy-duty machining scenarios such as milling and turning.

[0003] However, most existing carbide inserts have various problems. For example, in a carbide indexable milling insert disclosed in publication number CN208437734U, although it adopts a 25° large rake angle design to improve chip removal efficiency and economy, in the peripheral milling of cylindrical workpieces, such as shafts and tubes, traditional inserts need to rely on precision servo mechanisms or hydraulic systems to drive the insert to rotate around the workpiece coaxially in order to achieve multi-position switching. Such systems require high-precision positioning, real-time feedback control and frequent calibration, resulting in high equipment costs and high technical barriers to operation and maintenance, which have certain limitations.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] like Figures 1 to 4 As shown, a superhard alloy indexable cutting tool with heat dissipation micropores includes a support frame 1, a driven cylinder 2, a support plate 3, a support rod 4, a superhard alloy cutting tool 5, and an indexing mechanism 6. The support frame 1 has a through hole, the driven cylinder 2 is slidably engaged in the through hole, one end of the support plate 3 is fixed to the top of the driven cylinder 2, the support rod 4 is connected and locked to the other end of the support plate 3, and the superhard alloy cutting tool 5 is fixed on the support rod 4.

[0022] The indexing mechanism 6 is installed inside the support frame 1, and the indexing mechanism 6 includes an indexing cylinder 61, an indexing groove 62, an adjusting frame 63, a lever 64, a limiting groove 65, and a drive unit. The indexing cylinder 61 is rotatably connected inside the support frame 1. The indexing groove 62 is recessed in the peripheral wall of the indexing cylinder 61. The adjusting frame 63 is rotatably connected inside the support frame 1. The lever 64 is installed at the end of the adjusting frame 63 away from the support frame 1, and one end of the lever 64 is slidably engaged in the indexing groove 62. The limiting groove 65 is recessed in the peripheral wall of the driven cylinder 2, and the other end of the lever 64 is slidably engaged in the limiting groove 65.

[0023] The drive unit includes a transmission rod 66, an incomplete gear 67, a driven gear 68, and a driven rod 69. The transmission rod 66 and the driven rod 69 are rotatably connected to the support frame 1. The transmission rod 66 is located at the axis of the indexing cylinder 61. The incomplete gear 67 is coaxially fixed on the transmission rod 66. The indexing cylinder 61 is connected and locked to the incomplete gear 67. A through hole is provided through the axis of the driven cylinder 2. The driven rod 69 is slidably engaged in the through hole. The driven gear 68 is coaxially fixed on the driven rod 69 and meshes with the incomplete gear 67.

[0024] A protrusion 610 is fixed on the side wall of the passive rod 69, and a groove 611 is provided on the inner wall of the through hole of the driven cylinder 2. The protrusion 610 is slidably fitted in the groove 611.

[0025] The indexing cylinder 61 is available in various models, and the indexing cylinder 61 is detachably connected to the incomplete gear plate 67 by screws.

[0026] In this invention, by setting a indexing cylinder 61 with the same diameter as the workpiece and opening a standardized indexing groove 62 on its peripheral wall, a replaceable template structure is formed, which solves the problem of frequent tool path adjustment in traditional cylindrical workpiece milling. Moreover, the indexing cylinder 61 provides multiple models to adapt to different workpiece sizes, eliminating the need for reprogramming or calibration, significantly reducing changeover time and operational complexity. The supercarbide insert 5 is automatically indexed by using a lever 64, an incomplete gear 67, a driven gear 68, and a passive rod 69. The cutting path switching is completed entirely by mechanical structure, without relying on high-precision drive devices such as servo motors and hydraulic systems, simplifying the control process and reducing equipment costs, achieving a comprehensive breakthrough in low cost, high efficiency, and high precision. Example 2

[0027] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0028] The support plate 3 is provided with a strip groove, and the support rod 4 is slidably engaged in the strip groove and locked by locking screws, so that the position of the support rod 4 on the support plate 3 can be adjusted appropriately.

[0029] The surface of the supercarbide insert 5 is provided with heat dissipation micropores, and the heat dissipation micropores are arranged in a covering manner. Through the arrangement of heat dissipation micropores, the heat generated by the supercarbide insert 5 during processing can be dissipated quickly, avoiding overheating and damage to the supercarbide insert 5.

[0030] Working principle: When using this alloy insert, first connect the appropriate type of indexing cylinder 61 to the incomplete gear disk 67 according to the actual machining situation. Then, place the cylindrical workpiece on the top of the support frame 1 and make the workpiece and the driven cylinder 2 on the same axis. Then, drive the transmission rod 66 through the external drive device to drive the indexing cylinder 61 and the incomplete gear disk 67 to rotate. At this time, the lever 64 slides in the indexing groove 62. Through the limiting effect of the indexing groove 62, the adjusting frame 63 is driven to rotate and slides synchronously in the limiting groove 65. It also drives the driven cylinder 2 to slide on the driven rod 69, realizing the synchronous adjustment of the height of the supercarbide insert 5. When the incomplete gear disk 67 meshes with the driven gear 68, the driven gear 68 drives the driven rod 69 to rotate, and the driven rod 69 drives the driven cylinder 2 to rotate, so that the supercarbide insert 5 can perform indexing milling operation.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
