[0002] In the field of machining, high-precision machining of spline grooves has always been one of the key technologies, especially in applications requiring efficient, stable, and precise machining. However, existing spline groove machining equipment still has shortcomings in terms of machining efficiency, positioning accuracy, and ease of operation, affecting overall machining quality and production efficiency.

[0003] Currently, the machining of spline grooves on lead screws mainly relies on a fixture mechanism to fix the lead screw. After machining a single groove, the operator needs to manually adjust the position of the lead screw and perform multiple measurements to ensure the accuracy of machining the next groove. This operating method shows obvious defects in practical applications. Frequent disassembly and reassembly and repeated measurements not only significantly reduce the overall machining efficiency, but may also introduce errors due to human factors, leading to unstable machining accuracy.

[0004] The aforementioned problems indicate that existing spline groove machining equipment still has certain shortcomings in terms of machining accuracy and positioning stability. Therefore, this invention provides a magnetically attached lead screw high-precision spline groove machining device, which aims to achieve rapid clamping and high-precision positioning through magnetic positioning technology, thereby meeting the modern industrial demand for high-precision and high-efficiency spline groove machining.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention provides a high-precision machining device for magnetically chuckled lead screw spline grooves. Its core lies in the synergistic effect of an electromagnetic chuck, an indexing mechanism, and a fine-tuning mechanism, which achieves efficient, stable, and precise machining of lead screw spline grooves. The following is in conjunction with the appendix... Figure 1 To be continued Figure 3 The specific embodiments of the present invention will be described in detail below. Example

[0026] like Figure 1 As shown, a high-precision machining device for magnetically attracted lead screw spline grooves includes an operating table 1, a base 2, an electromagnetic chuck 3, a clamping mechanism 4, and an indexing mechanism 5. The operating table 1, serving as the foundation platform for the entire device, is made of high-strength steel to ensure sufficient rigidity and stability during machining. The base 2 is mounted on the operating table 1 and bolted to it, providing a stable mounting base for other components. The electromagnetic chuck 3 is mounted on the top surface of the base 2; it uses magnetic force to attract the lead screw, ensuring its stability during machining. A clamping mechanism 4 is mounted at one end of the electromagnetic chuck 3, and the indexing mechanism 5 is mounted on the clamping mechanism 4. The clamping mechanism 4 is used to fix the lead screw and works in conjunction with the indexing mechanism to achieve precise positioning and rotation. The clamping mechanism and the electromagnetic chuck work together to ensure the lead screw remains stable during machining, avoiding machining errors caused by vibration or displacement. A V-groove 6 is provided on one side wall of the electromagnetic chuck 3, and the V-groove 6 and the indexing mechanism 5 are located on the same side of the electromagnetic chuck 3; the V-groove 6 of the electromagnetic chuck 3 is used to precisely fix the position of the lead screw. In particular, the design of the V-groove enables the lead screw to automatically center during the adsorption process, reducing manual intervention while improving positioning accuracy and ensuring processing quality.

[0027] like Figure 2 , Figure 3and Figure 4 As shown, both sides of the base 2 are provided with horizontal fine-tuning mechanisms 7, which are fixed on the operating table 1. The horizontal fine-tuning mechanisms 7 are used to quickly adjust the horizontal position of the base 2.

[0028] Specifically, the horizontal fine-tuning mechanism 7 includes a fine-tuning mechanism base 71, a protective plate 72, a first fastener 73, a push plate 74, an adjusting bolt 75, and a second fastener 76. The fine-tuning mechanism base 71 is provided with a sliding groove 77, a channel 78, and a positioning groove 79. The sliding groove 77 is connected to the channel 78, and the channel 78 is orthogonal to the positioning groove 79. A push plate 74 is disposed within the sliding groove 77, and the inner wall of the sliding groove 77 is in contact with one side wall of the push plate 74. The inner wall of the sliding groove 77 is inclined and in contact with the push plate 74. An adjusting bolt 75 is disposed within the channel 78, and the positioning ring of the adjusting bolt 75 is located within the positioning groove 79. The adjusting bolt 75 is threadedly connected to the push plate 74. When the adjusting bolt 75 rotates clockwise or counterclockwise, the push plate 74 moves horizontally within the sliding groove 77, thereby pushing the base 2 to achieve fine-tuning of its horizontal position. The top surface of the fine-tuning mechanism base 71 is fixed with a protective plate 72 by a first fastener 73, which protects the internal structure. The fine-tuning mechanism base 71 is fixed to the operating table 1 by a second fastener 76. Through the design of the above structure, the horizontal fine-tuning mechanism 7 can precisely adjust the horizontal position of the base 2 within the micrometer range, ensuring the precise distance between the lead screw and the cutting tool of the processing equipment.

[0029] Specifically, a height fine-tuning mechanism 8 is provided below the base 2. The height fine-tuning mechanism 8 is located between the operating table 1 and the base 2. The height fine-tuning mechanism 8 is used to quickly adjust the height of the base 2 to adapt to different processing requirements. The design of the height fine-tuning mechanism 8 makes the height adjustment of the base more flexible and efficient, significantly shortening the preparation time before processing.

[0030] Specifically, the electromagnetic chuck 3 is also equipped with a cooling system, which includes a coolant pipeline and a nozzle. The coolant pipeline is connected to the nozzle, and the nozzle is located near the V-groove 6.

[0031] Specifically, the indexing mechanism 5 includes an indexing plate 51 and several indexing teeth 52. The indexing plate 51 has a centrally located internally threaded through-hole 53 for connecting to the lead screw. The indexing teeth 52 are evenly arranged around the indexing plate 51, and their number can be adjusted according to actual processing requirements. The indexing plate 51 and the indexing teeth 52 are manufactured using an integral molding process, ensuring the integrity of the structure and indexing accuracy. Through the precise indexing function of the indexing teeth 52, the indexing mechanism 5 can accurately stop the lead screw at a predetermined position after each rotation, thereby completing high-precision machining of multiple spline grooves. The number and distribution of the indexing teeth are designed according to actual processing requirements to meet the processing requirements of lead screws of different specifications.

[0032] The V-groove 6 on one side wall of the electromagnetic chuck 3 has an angle of 90°. The V-groove 6 is used to adsorb the lead screw and realize the automatic centering function.

[0033] A machining method for a high-precision machining device for magnetically attached lead screw spline grooves includes the following steps: S1. After connecting one end of the lead screw to the internal threaded through hole 53 of the indexing mechanism 5 by thread, fix the indexing mechanism 5 on the clamping mechanism 4; at this time, it is necessary to ensure that the connection between the lead screw and the indexing mechanism 5 is tight to avoid loosening; S2. Turn on the electromagnetic chuck 3 so that the other end of the lead screw is attracted to the V-groove 6 of the electromagnetic chuck 3. The magnetic strength of the electromagnetic chuck 3 can be adjusted through the control panel to accommodate lead screws of different materials and specifications. S3. The height of the base 2 is quickly adjusted by the height fine-tuning mechanism 8 to ensure that the lead screw axis is precisely aligned with the cutting tool of the processing equipment to meet the processing requirements; S4. Quickly adjust the horizontal position of the base 2 through the horizontal fine-tuning mechanism 7 to ensure that the lead screw and the cutting tool of the processing equipment maintain a precise distance. Specifically, rotate the adjusting bolt 75 and observe the movement of the push plate 74 until the processing requirements are met. S5. Start the processing equipment, and after completing the high-precision processing of a single spline groove, the indexing mechanism 5 is used to rotate the lead screw to complete the high-precision processing of multiple spline grooves.

[0034] The technical solution of this invention demonstrates significant technical effects in practical applications. First, the cooperation between the electromagnetic chuck 3 and the V-groove 6 improves the stability of the lead screw during machining, avoiding machining errors caused by vibration or displacement. Second, the precise indexing function of the indexing mechanism 5 ensures that the lead screw accurately stops at the predetermined position after each rotation, thereby significantly improving the indexing accuracy of spline groove machining. Third, the design of the horizontal fine-tuning mechanism 7 and the height fine-tuning mechanism 8 makes the position adjustment of the base 2 more convenient and precise, greatly reducing manual adjustment time and thus improving machining efficiency. Finally, the overall structure is rationally designed, and the connection relationships between the components are clear, facilitating practical application and maintenance. In summary, this invention provides a highly efficient, stable, and precise spline groove machining device through the organic combination of magnetic positioning technology, precision fine-tuning mechanism, and indexing mechanism. This device can significantly improve the shortcomings of existing technologies in practical applications and has significant industrial application value.
