[0016] Detailed technical solution description

[0017] Design and functional implementation of the displacement support structure

[0018] The indexing support structure is the foundation of the entire mechanism. Its main function is to provide stable support and ensure that the tool maintains a precise position during machining. The indexing support structure includes a carrier, a guide, and a sliding component. The carrier consists of a carrier platform with two mounting holes on its top to accommodate a support plate. The support plate is connected to a second support via bearings, ensuring free rotation. Additionally, a through hole is provided on the top of the carrier platform to reduce material weight and facilitate subsequent maintenance. The guide is in the form of a guide rail with a slider inside. The slider is fixed to the carrier platform with screws, thereby enabling horizontal movement of the carrier platform.

[0019] Design and functional implementation of the indexing adjustment component

[0020] The indexing adjustment assembly is the core component for adjusting the tool angle, and it mainly consists of a rotating block, limiting grooves, and locating pins. The rotating block is connected to the second support via a bushing, ensuring it can rotate freely within a certain range. Several limiting grooves are provided on the outer side of the rotating block; the spacing between these grooves is precisely calculated to meet the machining requirements of different angles. After the locating pin is embedded in the limiting groove, a certain amount of friction is provided by an elastic washer to prevent the locating pin from loosening during machining.

[0021] The fit between the guide component and the sliding component

[0022] The guide component adopts a guide rail design, with a return spring inside. One end of the return spring is fixedly connected to the slider. When the support platform needs to move horizontally, the slider slides along the guide rail, and the return spring provides a certain restoring force, ensuring that the support platform automatically returns to its initial position after processing. This design not only improves the ease of operation but also reduces the need for manual intervention.

[0023] Functions of support plate and buffer washer

[0024] A buffer washer is fixed to the outer side of the support plate. The buffer washer is made of polyurethane, which has good wear resistance and impact resistance. During the tooling process, the buffer washer can effectively absorb vibration, reduce the wear of mechanical parts, and improve machining accuracy.

[0025] Overall working principle

[0026] In actual use, the operator first fixes the tool on the rotating block, and then adjusts the angle of the rotating block according to the machining requirements. After adjustment, the locating pin is inserted into the corresponding limit groove, and the angle is fixed by the friction provided by the elastic pad. Subsequently, the support table moves horizontally along the guide rail, allowing the tool to enter the machining position. After machining is completed, the return spring pushes the slider back to the initial position, completing one machining cycle.

[0027] Technical Advantages Analysis

[0028] This invention achieves multi-angle positioning and fixation of the cutting edge during tool machining through the synergistic action of the indexing adjustment component and the indexing support structure. Compared with traditional indexing mechanisms, this invention eliminates the need for complex gear transmissions and frequent locking operations, greatly simplifying the operation process. Simultaneously, the design of the buffer washer and return spring effectively reduces wear on mechanical parts, extending the service life of the equipment. Furthermore, the cooperation of the guide and sliding components makes the horizontal movement of the support table more stable, further improving machining accuracy.

[0037] This utility model provides a lathe tool cutting edge machining indexing mechanism, such as... Figures 1 to 5As shown, its main structure includes a rotation support structure 1 and a rotation adjustment assembly 2. The top of the rotation support structure 1 is provided with a support platform 3, which serves as a support for installing and fixing other components, and the rotation adjustment assembly 2 is installed inside it. Guide rails 9 are provided on both sides of the support platform 3 as guides, and sliders 10 are slidably connected inside the guide rails 9 as sliding components. The sliders 10 are fixedly connected to the support platform 3 by screws. The core part of the rotation adjustment assembly 2 is a rotating block 4. A limiting groove 5 is provided on the outer side of the rotating block 4, and a positioning pin 6 is provided between the limiting grooves 5. An elastic washer 7 is embedded at the end of the positioning pin 6. The rotation support structure 1 also includes two support plates 8, which are rotatably connected to the inner side of the second support 15 via bearings. The rotating block 4 is rotatably connected between the two second supports 15 via bushings. The outer sides of the two support plates 8 are respectively fixedly connected to the first support by bolts. A buffer washer 12, made of polyurethane, is fixedly provided on the outer side of the support plate 8 to absorb vibration and reduce wear.

[0038] Combination Figure 1 As can be seen, the top of the support platform 3 has two mounting holes 13, and two support plates 8 are located inside the two mounting holes 13 respectively. The design of the mounting holes 13 allows the support plates 8 to be stably embedded within them, while ensuring the assembly accuracy between the support plates 8 and the support platform 3. The top of the support platform 3 also has a through hole 14, located between the two mounting holes 13, which is used to reduce the overall weight and facilitate subsequent maintenance operations. Figure 3 As shown, a return spring 11 is provided inside the guide rail 9. One end of the return spring 11 is fixedly connected to the slider 10, and the other end is fixedly connected to the inner wall of the guide rail 9. The function of the return spring 11 is to provide a restoring force when the slider 10 slides along the guide rail 9, so that the support platform 3 can automatically return to the initial position after completing the horizontal movement.

[0039] Combination Figure 2 Further details about the specific structure of the indexing adjustment assembly 2 can be obtained. The rotating block 4 is connected to two secondary supports 15 via bushings, ensuring free rotation within a certain range. The outer side of the rotating block 4 is provided with limiting grooves 5. The number and spacing of the limiting grooves 5 are precisely designed to meet the processing requirements of different angles. After the positioning pin 6 is inserted into the limiting groove 5, the angle is fixed by the friction provided by the elastic washer 7. The end of the positioning pin 6 is embedded with an elastic washer 7. The presence of the elastic washer 7 not only increases the contact area between the positioning pin 6 and the limiting groove 5 but also provides appropriate friction to prevent loosening during processing. A buffer washer 12 is fixedly provided on the outer side of the support plate 8. The position of the buffer washer 12 is as follows... Figure 4 As shown, it is made of polyurethane, which has good wear resistance and impact resistance. During the tooling process, the buffer washer 12 can effectively absorb vibration, reduce the wear of mechanical parts, and improve machining accuracy.

[0040] In actual use, the operator first fixes the cutting tool on the rotating block 4, and then adjusts the angle of the rotating block 4 according to the machining requirements. Specifically, the rotating block 4 is connected to the second support 15 through a bushing, allowing it to rotate freely within a certain range. After adjustment, the locating pin 6 is inserted into the corresponding limiting groove 5, and the angle is fixed by the friction provided by the elastic pad 7. Subsequently, the support table 3 moves horizontally along the guide rail 9, allowing the cutting tool to enter the machining position. Figure 3 As shown, when the slider 10 slides along the guide rail 9, the return spring 11 provides a certain restoring force to ensure that the support table 3 can automatically return to its initial position after processing. This design reduces the need for manual intervention and improves the convenience of operation. After processing, the return spring 11 pushes the slider 10 back to its initial position, completing one processing cycle.

[0041] The horizontal movement of the support platform 3 is achieved through the cooperation of the guide rail 9 and the slider 10. A return spring 11 is installed inside the guide rail 9, with one end fixedly connected to the slider 10 and the other end fixedly connected to the inner wall of the guide rail 9. When the support platform 3 needs to move horizontally, the slider 10 slides along the guide rail 9, and the return spring 11 provides a restoring force, allowing the support platform 3 to automatically return to its initial position after machining. This design not only improves operational convenience but also reduces the need for manual intervention. A buffer washer 12 is fixedly installed on the outer side of the support plate 8. The buffer washer 12 is made of polyurethane, which has good wear resistance and impact resistance. During tool machining, the buffer washer 12 can effectively absorb vibration, reduce wear on mechanical parts, and improve machining accuracy.

[0042] The operating principle of the entire mechanism is as follows: First, the cutting tool is fixed on the rotating block 4, and then the angle of the rotating block 4 is adjusted according to the machining requirements. The rotating block 4 is connected to the second support 15 through a bushing, allowing it to rotate freely within a certain range. After adjustment, the positioning pin 6 is inserted into the corresponding limit groove 5, and the angle is fixed by the friction provided by the elastic washer 7. Subsequently, the support table 3 moves horizontally along the guide rail 9, allowing the cutting tool to enter the machining position. When the slider 10 slides along the guide rail 9, the return spring 11 provides a certain restoring force, ensuring that the support table 3 can automatically return to the initial position after machining. After machining, the return spring 11 pushes the slider 10 back to the initial position, completing one machining cycle. The buffer washer 12 absorbs vibration during machining, reduces wear on mechanical parts, and improves machining accuracy.

[0043] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0044] In the actual operation of machining cutting edges on a lathe, the tool to be machined is first fixed in the mounting position of the rotary block 4. This installation process is completed by bolts or clamping devices to ensure that the tool will not loosen during machining. Subsequently, the angle of the rotary block 4 is adjusted according to the machining requirements. The rotary block 4 is connected to two secondary supports 15 through bushings, allowing it to rotate freely within a certain range. When adjusting the angle, the operator manually rotates the rotary block 4 to the desired position and inserts the locating pin 6 into the corresponding limiting groove 5. The end of the locating pin 6 is embedded with an elastic washer 7. The presence of the elastic washer 7 increases the contact area between the locating pin 6 and the limiting groove 5 and provides appropriate friction. This design allows the rotary block 4 to remain stable during machining, avoiding angular deviation caused by vibration or external forces.

[0045] After the angle adjustment is completed, the support platform 3 moves horizontally along the guide rail 9, allowing the tool to enter the machining position. For example... Figure 3 As shown, a return spring 11 is installed inside the guide rail 9. One end of the return spring 11 is fixedly connected to the slider 10, and the other end is fixedly connected to the inner wall of the guide rail 9. When the support table 3 needs to move horizontally, the slider 10 slides along the guide rail 9, and the return spring 11 is stretched or compressed, providing a certain restoring force. This design ensures that the support table 3 can automatically return to its initial position after processing, reducing the need for manual intervention. At the same time, the cooperation between the slider 10 and the guide rail 9 ensures the smooth movement of the support table 3, avoiding the impact of shaking on processing accuracy.

[0046] During tool machining, a buffer washer 12 is fixedly installed on the outer side of the support plate 8. The buffer washer 12 is made of polyurethane and has good wear resistance and impact resistance. When the tool is performing cutting operations, the buffer washer 12 can effectively absorb vibration and reduce the wear of mechanical parts. In addition, the buffer washer 12 can also reduce the noise generated during tool machining, further improving the working environment.

[0047] After processing is complete, the return spring 11 pushes the slider 10 back to its initial position, and the support platform 3 returns to its origin. At this time, the operator can pull the positioning pin 6 out of the limit groove 5 and readjust the angle of the rotating block 4 according to the next processing requirements. The design of the entire processing cycle not only simplifies the operation process but also significantly improves processing efficiency and equipment lifespan.

[0048] To facilitate maintenance and reduce overall weight, the top of the support platform 3 has two mounting holes 13 and one through hole 14. Two support plates 8 are located inside the two mounting holes 13, respectively. The design of the mounting holes 13 allows the support plates 8 to be stably embedded within them, while ensuring the assembly accuracy between the support plates 8 and the support platform 3. The through hole 14 is located between the two mounting holes 13, used to reduce overall weight and facilitate subsequent maintenance operations. For example, when it is necessary to replace the buffer washer 12 or check the condition of the return spring 11, this can be done quickly through the through hole 14.

[0049] As can be seen from the above steps, this utility model achieves multi-angle positioning and fixation of the cutting edge during the machining process of the tool through the synergistic effect of the indexing adjustment component 2 and the indexing support structure 1. Its core lies in the precise fit between the rotating block 4 and the limiting groove 5, as well as the functional design of the return spring 11 and the buffer washer 12. These designs collectively ensure the stability, accuracy, and convenience of the machining process, thereby significantly improving the overall efficiency and quality of lathe tool cutting edge machining.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
