Description

Technical Field

[0001] The utility model relates to the technical field of synchronous electric spindles, in particular to a turning-milling compound synchronous electric spindle. Background Technique

[0002] Implementing a turning-milling compound synchronous electric spindle is a technology through which the cutting processes of two different functions, namely a lathe and a milling machine, can be carried out on the same machine tool. Among them, the rotation speed and position of two tools are controlled by the electric spindle to achieve efficient and precise machining, improve machining efficiency, save working space and costs, and at the same time can flexibly meet the processing requirements of complex workpieces, simplify the production process, reduce equipment switching time, and improve production efficiency and machining accuracy.

[0003] As the core component, the electric spindle is responsible for controlling the rotation speed and position of the turning tool and the milling cutter, and is usually equipped with a high-precision servo system to ensure precise machining. The control system is responsible for integrating and synchronizing the two machining functions, and generating and executing the compound machining path through numerical control programming.

[0004] However, when replacing the tool head of the existing compound electric spindle, it takes a long time. Since the connection between the tool head and the spindle is relatively complex and requires manual disassembly and replacement by the staff, the work efficiency is low, and the coolant of the electric spindle cannot be adjusted according to the working state, so the flexibility is not high. Therefore, a turning-milling compound synchronous electric spindle is proposed. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a turning-milling compound synchronous electric spindle, aiming to improve the problem of low work efficiency caused by inconvenient tool head replacement in the existing technology.

[0006] To achieve the above object, the utility model provides the following technical solution: A turning-milling compound synchronous electric spindle includes a cooling cylinder. One side of the outer wall of the cooling cylinder is provided with a bearing, and a middle shaft is rotatably connected inside the bearing. A clamping groove is opened inside the middle shaft, and a first fitting block is slidably connected inside the middle shaft. A fixed shaft is fixedly connected inside the first fitting block, a convex block is rotatably connected to the outer wall of the fixed shaft, an inclined block is fixedly connected to one side of the outer wall of the convex block, a first groove is opened inside the first fitting block, a second fitting block is slidably connected to the outer wall of the convex block, a sliding block is slidably connected inside the second fitting block, a second groove is opened inside the second fitting block, and an adjusting component is provided at one end of the cooling cylinder, and the adjusting component is used to adjust the flow rate of the coolant inside the cooling cylinder.

[0007] Further, the adjusting component includes a sealing ring, the inner wall of the sealing ring abuts against the outer wall of the cooling cylinder, and a coolant inlet is fixedly connected inside the sealing ring.

[0008] Further, a rotating block is rotatably connected inside the sealing ring, and a first round hole is formed inside the rotating block.

[0009] Further, one side of the outer wall of the rotating block is rotatably connected to a fixed block, and a second round hole is formed inside the fixed block.

[0010] Further, one side of the outer wall of the fixed block is fixedly connected to the inner wall of the sealing ring.

[0011] Further, a limiting block is rotatably connected to the outer wall of the central axis, the outer wall of the limiting block is fixedly connected to the inner wall of the cooling cylinder, and a chamber is arranged inside the limiting block.

[0012] Further, the outer wall of the beveled block is slidably connected to the inner wall of the first groove, and the outer wall of the convex block is rotatably connected to the inside of the first fitting block.

[0013] Further, the outer wall of the convex block abuts against the inner wall of the clamping groove, and one side of the outer wall of the second groove abuts against the outer wall of the convex block.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the convex block is guided by the first groove to rotate by sliding the first fitting block inside the second fitting block, so that the convex block is stuck inside the second fitting block. The sliding block further limits the convex block, achieving fast installation and disassembly while realizing the firm connection between the first fitting block, the second fitting block and the limiting block, improving the practicability of the motorized spindle and the working efficiency.

[0016] 2. In the utility model, by rotating the rotating block on one side of the outer wall of the fixed block, the overlapping part between the first round hole and the second round hole can be adjusted, so as to control the speed of the coolant entering the chamber, and further achieve the effect of adjusting the flow rate of the coolant according to the working state of the motorized spindle. The coolant enters the chamber from the second round hole, ensuring the uniform distribution of the coolant and achieving the effect of improving the cooling efficiency. Description of the Drawings

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Refer to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: A compound turning and milling synchronous electric spindle, including a cooling cylinder 1, a bearing 12 is arranged on one side of the outer wall of the cooling cylinder 1, a central axis 2 is rotatably connected inside the bearing 12, a card slot 3 is opened inside the central axis 2, a first fitting block 4 is slidably connected inside the central axis 2, a fixed shaft 5 is fixedly connected inside the first fitting block 4, a convex block 6 is rotatably connected to the outer wall of the fixed shaft 5, a bevel block 11 is fixedly connected to one side of the outer wall of the convex block 6, a first groove 7 is opened inside the first fitting block 4, a second fitting block 8 is slidably connected to the outer wall of the convex block 6, a sliding block 9 is slidably connected inside the second fitting block 8, a second groove 10 is opened inside the second fitting block 8, and an adjusting component is arranged at one end of the cooling cylinder 1, and the adjusting component is used to adjust the flow rate of the coolant inside the cooling cylinder 1.

[0024] Specifically, by controlling the first fitting block 4 to slide into the second fitting block 8, the bevel block 11 connected to the convex block 6 slides in the first groove 7, and then the convex block 6 is rotated, so as to be stuck into the second fitting block 8 to achieve rapid connection. The sliding of the first fitting block 4 and the second fitting block 8 in the central axis 2 replaces the traditional shaft connection method. The sliding of the sliding block 9 and the first fitting block 4 enables the convex block 6 to easily release the second fitting block 8, realizing the convenient disassembly of the central axis 2, shortening the time for replacing the central axis 2, and improving work efficiency.

[0025] Refer to Figure 1 and Figure 2, the adjusting assembly includes a sealing ring 14. The inner wall of the sealing ring 14 abuts against the outer wall of the cooling cylinder 1. A coolant inlet 15 is fixedly connected inside the sealing ring 14. A rotating block 16 is rotatably connected inside the sealing ring 14. A circular hole 17 is formed inside the rotating block 16. One side of the outer wall of the rotating block 16 is rotatably connected to a fixed block 18. A circular hole 19 is formed inside the fixed block 18. One side of the outer wall of the fixed block 18 is fixedly connected to the inner wall of the sealing ring 14. The outer wall of the central shaft 2 is rotatably connected to a limiting block 20. The outer wall of the limiting block 20 is fixedly connected to the inner wall of the cooling cylinder 1. A chamber 13 is provided inside the limiting block 20. The outer wall of the bevel block 11 slides inside the first groove 7. The outer wall of the convex block 6 is rotatably connected inside the first fitting block 4. The outer wall of the convex block 6 abuts against the inner wall of the clamping groove 3. One side of the outer wall of the second groove 10 abuts against the outer wall of the convex block 6.

[0026] Specifically, the convex block 6 and the bevel block 11 ensure a firm connection between the first fitting block 4, the second fitting block 8 and the limiting block 20, effectively solving the problems of complex tool changing steps and long time consumption of traditional motor spindles. The coolant enters the chamber 13 through the coolant inlet 15. The rotating block 16 adjusts the coincidence degree of the circular hole 17 and the circular hole 19, controls the flow rate of the coolant in the chamber 13, selects an appropriate cooling efficiency according to the state of the motor spindle, improves the energy utilization efficiency, and the circular hole 17 supplies the coolant into the chamber 13 from different directions to ensure the uniform distribution of the coolant and improve the cooling efficiency.

[0027] Working principle: When the turning-milling compound synchronous motor spindle needs to be used, by controlling the first fitting block 4 to be embedded inside the second fitting block 8, the bevel block 11 connected to the convex block 6 slides inside the first groove 7, so that the convex block 6 rotates and then is clamped inside the second fitting block 8 to achieve the effect of quick connection. The first fitting block 4 and the second fitting block 8 slide inside the central shaft 2, replacing the original shaft body to connect and fix the central shaft 2. The sliding block 9 slides and the first fitting block 4 slides, so that the convex block 6 connected to the first fitting block 4 can be disengaged from the second fitting block 8 to achieve the effect of easily disassembling the central shaft 2, reducing the time required for replacing the central shaft 2 and improving the work efficiency. The first fitting block 4, the second fitting block 8 and the limiting block 20 are firmly connected by the convex block 6 and the bevel block 11 to achieve the effect of improving the practicability of the motor spindle and solving the problems of many tool changing steps and long time consumption of traditional motor spindles. The coolant enters the chamber 13 from the coolant inlet 15. The rotating block 16 rotates to adjust the coincidence degree of the circular hole 17 and the circular hole 19, thereby controlling the flow rate of the coolant inside the chamber 13, selecting different cooling efficiencies in different states of the motor spindle, improving the energy utilization rate. At the same time, the coolant entering the chamber 13 from the circular holes 17 in different directions can ensure the uniform distribution of the coolant inside the chamber 13 to achieve the effect of improving the cooling efficiency.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
