Description

Technical Field

[0001] This utility model relates to the field of deep hole forming technology, specifically a deep hole forming tool. Background Technology

[0002] A deep hole forming tool is a cutting tool specifically designed for machining deep holes, typically used in deep hole machining operations such as drilling or reaming. Through specific tool design and machining methods, it can achieve efficient cutting at considerable hole depths.

[0003] Currently, commonly used deep hole forming tools are relatively long and prone to vibration during operation. The large amplitude of the vibration of the deep hole forming tool during operation directly affects the machining accuracy of the workpiece. In addition, since deep hole forming tools have many grooves for cutting the workpiece, these grooves are in direct contact with the air. The contact between the deep hole forming tool and the air increases the resistance between the deep hole forming tool and the working air, thereby increasing the power consumption of the deep hole forming tool during operation.

[0004] Therefore, we propose a deep hole forming tool to solve the above problems. Utility Model Content

An anti-vibration component is disposed between the forming tool body and the connecting block. The anti-vibration component is used to reduce the vibration amplitude during the rotation of the forming tool body.

[0010] Furthermore, the anti-shake component includes a limiting post sleeved on the connecting block and multiple limiting sliders fixedly disposed on the outer wall of the forming blade body. The limiting post has an insertion port at one end opposite to the forming blade body, and one end of the forming blade body is inserted into the insertion port on the limiting post.

[0011] Furthermore, the insertion port is provided with multiple limiting grooves, and the multiple limiting grooves correspond to the positions of multiple limiting sliders on the forming blade body, and the multiple limiting sliders on the forming blade body are respectively slidably disposed in the multiple limiting grooves in the insertion port.

[0016] (3) Beneficial effects

[0024] 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.

[0025] Example

[0026] like Figure 1-4 As shown in the figure, a deep hole machining forming tool according to one embodiment of the present invention includes a forming tool body 1 and a connecting block 2. The connecting block 2 is fixedly disposed on the upper end face of the forming tool body 1. An anti-vibration component 3 is disposed between the forming tool body 1 and the connecting block 2. The anti-vibration component 3 is used to reduce the vibration amplitude during the rotation of the forming tool body 1.

[0027] like Figure 3 and Figure 4 As shown, the anti-shake component 3 includes a limiting post 301 sleeved on the connecting block 2 and multiple limiting sliders 302 fixedly disposed on the outer wall of the forming blade body 1. The limiting post 301 has an insertion port 3010 at its end opposite to the forming blade body 1, and one end of the forming blade body 1 is inserted into the insertion port 3010 on the limiting post 301. Multiple limiting grooves 303 are formed within the insertion port 3010, and the multiple limiting grooves 303 correspond to the positions of the multiple limiting sliders 302 on the forming blade body 1. Furthermore, the multiple limiting sliders 302 on the forming blade body 1 are slidably disposed within the multiple limiting grooves 303 within the insertion port 3010. A helical spring 304 is fixedly installed at the bottom inner side of the insertion port 3010. One end of the helical spring 304 is fixedly connected to the forming blade body 1 inserted into the insertion port 3010. A connecting ring 305 is fixedly installed on the lower end face of the limiting post 301. The connecting ring 305 and the limiting post 301 are concentric. A chip collection groove 306 and a plurality of chip removal grooves 307 are formed on the lower end face of the connecting ring 305. The plurality of chip removal grooves 307 are arranged at equal intervals and all of the plurality of chip removal grooves 307 communicate with the chip collection groove 306. The size of the limiting slider 302 is adapted to the size of the limiting slide groove 303.

[0028] The anti-vibration component 3 not only supports the rotating forming cutter body 1 on the workpiece, thus reducing the large vibrations that occur when the forming cutter body 1 rotates to process the workpiece due to its long length, thereby affecting the accuracy of the workpiece processing, but also shortens the length of the forming cutter body 1 exposed to the air. This reduces the air resistance between the groove on the forming cutter body 1 used for cutting the workpiece and the air, thereby saving the power consumption of the forming cutter body 1 when processing the workpiece, and thus achieving energy saving.

[0029] Multiple cutting edges 4 are fixedly provided on the outer wall surface of the forming tool body 1, and the multiple cutting edges 4 are arranged at equal intervals. Two chip discharge ports 5 are opened between two adjacent cutting edges 4, and an expansion groove 6 is opened at the bottom inner side of each chip discharge port 5.

[0030] By opening two chip removal ports 5 between two adjacent cutting edges 4, the efficiency of chip removal from the workpiece by the forming tool body 1 can be improved. By expanding the chip removal port 5 by setting the expansion slot 6 as the chip removal port, the blockage of the chip removal port 5 can be reduced.

[0031] The working principle of this practical application is as follows:

[0032] First, the forming cutter body 1 is connected to the machine tool via the connecting block 2. Then, the machine tool drives the forming cutter body 1 to rotate, and moves the rotating forming cutter body 1 towards the workpiece. While rotating, the forming cutter body 1 drives the connecting ring 305 to rotate through the cooperation of the limiting slide groove 303 and the limiting slider 302. When one end of the forming cutter body 1 contacts the workpiece, the forming cutter body 1 performs cutting on the workpiece. As the forming cutter body 1 continues to move downwards and deepens the cutting hole on the workpiece, the connecting ring 305 will press against the upper end face of the workpiece. At this time, the connecting ring 305 and the limiting post 301 provide stable support for the rotation of the forming cutter body 1. As the forming cutter body 1 continues to move downwards, the connecting block 2 pushes the forming cutter body 1 downwards along the limiting slide groove 303. During the process, the helical spring 304 is stretched under the force, and the downward movement of the forming cutter body 1 deepens the cutting hole on the workpiece. The chips cut by the forming cutter body 1 are discharged to the connecting ring 305 through the chip discharge port 5. The chips discharged to the connecting ring 305 are collected in the chip collection groove 306. As the forming cutter body 1 drives the limiting post 301 to rotate, the limiting post 301 drives the connecting ring 305 to rotate. The rotation of the connecting ring 305 will centrifuge the chips in its chip collection groove 306, and the centrifuged chips will be discharged through the chip discharge groove 307. When the cutting of the workpiece is finished and the forming cutter body 1 is pulled out of the hole on the workpiece, the helical spring 304 pushes the forming cutter body 1 to move along the limiting slide groove 303 through its own elastic characteristics and restores the forming cutter body 1 to its original position.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
