Description

Technical Field

[0001] The utility model belongs to the technical field of numerical control tool processing, and specifically relates to an alumina ceramic numerical control tool. Background Technique

[0002] A ceramic numerical control tool is a cutting tool made of ceramic materials and is widely used in metal processing, cutting, grinding and other processes. Compared with traditional metal tools, ceramic numerical control tools have high hardness, excellent wear resistance, can withstand high-temperature, high-speed and heavy-load cutting conditions without easy wear, and also have good high-temperature stability and heat resistance, can maintain good cutting performance under high-temperature cutting conditions. At the same time, the surface of the ceramic numerical control tool is smooth and has a low friction coefficient. The ceramic material has a lower density than the metal material, so the ceramic numerical control tool is relatively light, reducing the equipment load and the burden of the operator;

[0003] When the blade of the traditional alumina ceramic numerical control tool is clamped, the force-bearing area is small, resulting in low stability during the operation of the tool. In addition, the position of the tool tip of the tool cannot be precisely fine-tuned through the tool itself, restricting its application range. Therefore, it is urgently needed to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above technical problems, and its technical solution is as follows:

[0005] An alumina ceramic numerical control tool includes a diamond blade made of alumina ceramic and an adjustable tool shank. The adjustable tool shank includes a tool tip and a main body. The tool tip is slidably connected to the main body through an adjustment assembly. An adjustment limiting member is also provided on the adjustment assembly. A fixing block is provided at the front end of the tool tip. A pressing block is cooperatively connected above the fixing block through a connection assembly. Tips are correspondingly provided on the fixing block and the pressing block. And a diamond tool placement groove is provided at the top of the tip of the fixing block, and the front edge of the diamond tool placement groove corresponds to the sharp angle of the tip. The diamond blade matches the diamond tool placement groove and is installed in the diamond tool placement groove.

[0006] Preferably, a regular polygon limiting block is provided in the diamond tool placement groove, and a limiting groove matching the regular polygon limiting block is provided on the bottom side of the diamond blade, which helps the diamond blade to be evenly stressed and improves the stability of clamping the diamond blade.

[0007] Preferably, the connection assembly includes a screw rod and a sheep's horn nut. The screw rod is fixed in the middle of the top end of the fixing block. A through hole matching the screw rod is provided in the middle of the pressing block. The screw rod passes through the through hole and is threadedly connected to the sheep's horn nut. This setting improves the convenience of disassembling and assembling the diamond blade.

[0008] Preferably, a chute is provided at the front end of the main body, and the rear end of the cutter head is provided with a sliding part that matches the chute. A lead screw is rotatably connected to the middle of the sliding part near the chute end. A threaded hole that matches the lead screw is provided in the main body, and the threaded hole communicates with the chute. The lead screw is threadedly connected to the threaded hole, and the lead screw penetrates through the main body and is connected with an adjusting limit member. A rotating block is fixedly connected to one end of the lead screw away from the sliding part. With this setting, by rotating the lead screw, the cutter head can be displaced back and forth relative to the fixed main body, so as to facilitate the adjustment of the position of the cutter head.

[0009] Preferably, the adjusting limit member is a locking nut, and the locking nut is threadedly connected to the lead screw. After the cutter head is adjusted in place, hold the rotating block tightly and tighten the locking nut to achieve adjustment and limitation.

[0010] Preferably, the lead screw is rotatably connected to the sliding part through a bearing, which is convenient for operation.

[0011] Preferably, a micrometer scale is provided at the top of the sliding part along the sliding direction, which is convenient for precisely adjusting the position of the cutter head.

[0012] The present utility model further includes other components that can enable a kind of alumina ceramic numerical control tool to be used normally, which are all conventional means in the art. In addition, devices or components not defined in the present utility model adopt the existing technologies in the art.

[0013] The working principle of the present utility model is that through the cooperation of the tip of the pressing block and the tip of the fixed block, the contact area when clamping the diamond blade is increased, so that the force on the diamond blade is more uniform during work, thereby improving the stability of the tool during work. By providing an adjusting component and an adjusting limit member on the adjustable tool rod, the cutter head can achieve a certain displacement adjustment on the main body, so as to realize more application scenarios. For example, when the adjustment mechanism of the tool fixing seat of the numerical control machine tool fails, the fine adjustment of the cutter head position can still be realized through the adjustment function of the tool itself.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: the device increases the force-bearing area when clamping the diamond blade, improves the stability of the tool during work, and in addition, the position of the cutter head of the tool can be precisely fine-tuned through the tool itself, expanding the application range.

[0021] As Figures 1 to 4 As shown, an alumina ceramic numerical control cutter proposed in this embodiment includes a rhombic blade 1 made of alumina ceramic and an adjustable tool bar. The adjustable tool bar includes a cutter head 2 and a main body 3. The cutter head is slidably connected to the main body through an adjustment assembly. An adjustment limiting member 4 is further provided on the adjustment assembly. A fixing block 5 is provided at the front end of the cutter head. A pressing block 6 is connected in cooperation with the fixing block through a connection assembly above the fixing block. Tips 7 are correspondingly provided on the fixing block and the pressing block. A rhombic tool placement groove 8 is provided at the top of the tip of the fixing block. The front edge of the rhombic tool placement groove corresponds to the sharp angle of the tip. The rhombic blade is matched with the rhombic tool placement groove and installed in the rhombic tool placement groove.

[0022] In this embodiment, a regular quadrilateral limiting block 9 is provided in the rhombic tool placement groove. A limiting groove (not shown in the figure) matching the regular quadrilateral limiting block is provided on the bottom side of the rhombic blade, which helps the rhombic blade to be evenly stressed and improves the stability of clamping the rhombic blade.

[0023] Specifically, the connection assembly includes a screw 10 and a split nut 11. The screw is fixed in the middle of the top end of the fixing block. A through hole (not shown in the figure) matching the screw is provided in the middle of the pressing block. The screw passes through the through hole and is threadedly connected to the split nut. This setting improves the convenience of disassembling and assembling the rhombic blade.

[0024] More specifically, a sliding groove 12 is provided at the front end of the main body. The rear end of the cutter head is provided with a sliding portion 13 matching the sliding groove. A lead screw 14 is rotatably connected to the middle of the sliding portion near the sliding groove end through a bearing. A threaded hole 15 matching the lead screw is provided in the main body, and the threaded hole is communicated with the sliding groove. The lead screw is threadedly connected to the threaded hole, and the lead screw passes through the main body and is connected to an adjustment limiting member. The adjustment limiting member is a locking nut. A rotating block 16 is fixedly connected to the end of the lead screw away from the sliding portion. With this setting, by rotating the lead screw, the cutter head can move back and forth relative to the fixed main body. After the cutter head is adjusted in place, hold the rotating block tightly and tighten the locking nut to achieve adjustment limiting.

[0025] In addition, a micrometer scale 17 is provided at the top end of the sliding portion along the sliding direction, which is convenient for precisely adjusting the position of the cutter head.

[0026] The working principle of the present utility model is that through the cooperation of the tip of the pressing block and the tip of the fixed block, the contact area when clamping the diamond blade is increased, so that the force on the diamond blade during operation is more uniform, thereby improving the stability of the tool during operation. By setting an adjustment component and an adjustment limiting member on the adjustable tool rod, the tool head can achieve a certain displacement adjustment on the main body, so as to realize more application scenarios. For example, when the adjustment mechanism of the tool fixing seat of a CNC machine tool fails, the fine adjustment of the tool head position can still be achieved through the adjustment function of the tool itself.
