Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC milling machine technology, and in particular to a CNC milling machine for producing slot wedges. Background Technology
[0002] In today's industrial manufacturing field, slotted wedges are key components in equipment such as motors, and their quality and precision have a crucial impact on the performance of the entire equipment. As the manufacturing industry continues to demand higher precision, efficiency, and automation in component processing, traditional processing methods for slotted wedge production can no longer meet the growing production needs. For example, when processing slotted wedges, ordinary milling machines rely on manual operation to control the movement of the worktable and the cutting of the tool. This not only makes it difficult to guarantee processing precision but also results in low production efficiency, making it unable to adapt to the pace of mass production. Against this backdrop, a CNC milling machine for slotted wedge production has emerged. It integrates advanced CNC technology and mechanical manufacturing processes, aiming to achieve high-quality and high-efficiency slotted wedge production through precise automated control.
[0003] Existing conventional milling machines used for slot wedge production primarily consist of basic components such as the bed, worktable, and milling spindle. The bed, serving as the support structure, is typically made of cast iron to ensure machine stability. The worktable holds the slot wedge workpiece and is moved laterally and longitudinally along guide rails by a manual crank, adjusting the workpiece's machining position. The milling spindle is driven by a motor and uses milling cutters of different sizes to mill the workpiece. Its speed is usually adjusted by changing a limited number of fixed speeds. Technically, operators rely on their experience and pre-prepared machining drawings to manually operate each component. For example, they manually turn the crank to move the worktable to the intended starting point, then start the spindle to rotate the milling cutter, and continue moving the worktable to allow the cutter to mill the workpiece along a predetermined path. The entire process relies on frequent manual intervention and skill to ensure machining accuracy.
[0004] However, existing conventional milling machines have significant shortcomings in machining slot wedges. During the milling process, the friction between the tool and the workpiece over a long period of time generates a large amount of heat. Due to the lack of a dedicated cooling mechanism, the heat accumulates continuously, making the tool prone to excessive wear due to high temperatures, thus shortening the tool's service life. At the same time, it also leads to a decrease in the machining accuracy of the workpiece and problems such as dimensional deviations, which seriously affect the quality of slot wedge production and subsequent performance, and are not conducive to efficient and stable slot wedge production. Therefore, a CNC milling machine for slot wedge production is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a CNC milling machine for producing slot wedges, aiming to improve the problem of the lack of effective cooling measures in the prior art, which leads to easy tool wear and affects the machining accuracy of the workpiece.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A CNC milling machine for producing slot wedges includes a support frame, a sliding column slidably connected inside the support frame, a machining head slidably connected inside the sliding column, and a cooling assembly provided on the side of the support frame for rapidly cooling the equipment.

[0012] An electric push rod is fixedly connected to the top of the support plate, and a transmission rod is fixedly connected to the output end of the electric push rod.
[0013] As a further description of the above technical solution:
[0014] The top of the support plate is fixedly connected to a slide rail, and the transmission rod slides on the outer wall of the slide rail.
[0015] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, gas is compressed and delivered into the connecting pipe by an air pump. The gas is guided to the nozzle by the connecting pipe and sprayed out by the nozzle to cool the equipment. When it needs to be moved, the sliding frame is moved by pulling the handle to slide on the outer wall of the connecting frame, thereby achieving the effect of rapid cooling of the equipment. This solves the problem that the equipment is prone to overheating due to the heat generated during processing, which affects the processing accuracy and tool life. It improves the overall efficiency and product quality of slot wedge production.
[0025] 2. In this utility model, the output end of the electric push rod drives the transmission rod to slide on the outer wall of the slide rail, thereby making the clamping plate move synchronously. The movement of the transmission rod causes the connecting rod to move synchronously, which in turn drives the clamping plate on the other side to move synchronously. This achieves the effect of quickly limiting and adjusting the position of the workpiece, solving the problem of inaccurate workpiece positioning and easy processing deviation, and improving the accuracy and efficiency of production.

[0031] 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.
[0032] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a CNC milling machine for producing slot wedges, comprising a support frame 1, which serves as the main support for the entire equipment. The support frame 1 is structurally robust and can effectively support other components. A sliding column 2 is slidably connected inside the support frame 1, and a machining head 3 is slidably connected inside the sliding column 2. A cooling assembly is provided on the side of the support frame 1 for rapidly cooling the equipment.
[0033] The cooling assembly includes a connecting frame 4, which is fixedly connected to the side of the support frame 1. A sliding frame 5 is slidably connected to the outer wall of the connecting frame 4 to provide a base for sliding and stable support. A handle 6 is fixedly connected to the side wall of the sliding frame 5, allowing the operator to easily adjust the position of the cooling device to maximize the cooling effect. An air pump 7 is fixedly connected inside the sliding frame 5 to compress gas and provide power. A connecting pipe 8 is fixedly connected to the output end of the air pump 7, and a nozzle 9 is fixedly connected to one end of the connecting pipe 8 to blow out the gas. A limit component is provided inside the support frame 1 to quickly limit the workpiece.
[0034] Specifically, during milling operations on a CNC milling machine used for slot wedge production, the prolonged friction between the tool and workpiece generates significant heat, impacting tool life and workpiece machining accuracy. Air pump 7 compresses the surrounding air to enhance its cooling capacity. The compressed air is then transported through the connecting pipe of air pump 7 to the connecting pipe 8, which serves as a channel for airflow transmission, ensuring a stable supply of compressed air to critical components. Nozzle 9 is the final outlet for the airflow, ejecting compressed air at high speed. This powerful airflow cools the equipment, and the rapid flow of the ejected air effectively reduces the temperature of the workpiece and machining head 3, preventing excessive heat generation during prolonged operation that could degrade equipment performance or affect workpiece accuracy. When the position of the cooling component needs to be adjusted, the operator can do so by pulling handle 6. Handle 6 plays a guiding and controlling role. Under the pulling force, the sliding frame 5 slides along the outer wall of the connecting frame 4. As a supporting component of the cooling component, the sliding frame 5 slides smoothly on the outer wall of the connecting frame 4. Through the movement of the sliding frame 5, the position of the nozzle 9 can be quickly changed, thereby adjusting the effective range of the cooling component to adapt to different processing scenarios. When the equipment needs to cool different parts, pulling handle 6 can quickly and easily complete the position adjustment, ensuring that the cooling system can always accurately act on the parts that need cooling, thereby improving the overall processing efficiency.
[0035] Reference Figure 3 The limiting component includes a processing table 10 and a support plate 11. The processing table 10 is slidably connected inside the support frame 1 and can slide smoothly back and forth, up and down, or left and right within the support frame 1. The support plate 11 is fixedly connected to the upper surface of the processing table 10. An electric push rod 12 is fixedly connected to the top of the support plate 11. The electric push rod 12 is a drive device that can precisely control the stroke and is used to push or pull the component for position adjustment. A transmission rod 14 is fixedly connected to the output end of the electric push rod 12. A slide rail 13 is fixedly connected to the top of the support plate 11. The slide rail 13 provides the sliding trajectory of the transmission rod 14, ensuring that it is smooth and not easily deviated during transmission. The transmission rod 14 slides on the outer wall of the slide rail 13. A clamping plate 15 is fixedly connected to the top of the transmission rod 14. The function of the clamping plate 15 is to firmly clamp the workpiece on the processing table 10 and ensure the stability of the workpiece during processing. A connecting rod 16 is rotatably connected inside the transmission rod 14.
[0036] Specifically, during CNC milling of the slotted wedge, to prevent unforeseen circumstances from causing overtravel of moving parts or inaccurate workpiece positioning, which could affect machining accuracy and machine tool safety, the electric push rod 12 provides a power source for the entire device through its output end. The function of the electric push rod 12 is to transmit power to the transmission rod 14 through linear motion, pushing it to slide along the outer wall of the slide rail 13. The slide rail 13 acts as a stable guide device, ensuring that the transmission rod 14 can move smoothly and accurately along the predetermined track. During the sliding process of the transmission rod 14, it directly acts on the clamping plate 15, causing the clamping plate 15 to move inward synchronously. The movement of the clamping plate 15 clamps the workpiece, ensuring that the workpiece remains stable during machining and avoiding problems such as displacement or inaccurate positioning.
[0037] Reference Figure 3 A rotating disk 17 is rotatably connected to one side of the connecting rod 16. The rotating disk 17 allows it to rotate around the surface of the support plate 11, forming a flexible rotating support structure. The rotating disk 17 is rotatably connected to the surface of the support plate 11. A connecting rod 18 is rotatably connected inside the rotating disk 17 to ensure that it can remain stable during the rotation of the rotating disk 17. A transmission rod 19 is rotatably connected to one side of the connecting rod 18. A slide rail 20 is rotatably connected to one side of the transmission rod 19. The function of the slide rail 20 is to further move and position. The slide rail 20 is fixedly connected to the top of the support plate 11.
[0038] Specifically, during the sliding process of transmission rod 14, it also drives connecting rod 16 to deflect. The deflection of connecting rod 16 is transmitted through rotating disk 17, causing rotating disk 17 to rotate in the opposite direction. The rotation of rotating disk 17 provides driving force for connecting rod 18, causing connecting rod 18 to slide synchronously along the outer wall of slide rail 20. Slide rail 20 serves as a guide structure for connecting rod 18, ensuring its stable and precise movement during transmission. The sliding of connecting rod 18 drives another clamping plate 15 to move synchronously in the opposite direction, ensuring that the workpiece maintains a suitable limiting position during processing. The synchronous movement of the two clamping plates 15 allows the workpiece to be quickly limited, and its position can be finely adjusted as needed during processing, thus ensuring that the workpiece is always kept in the ideal processing position. In this way, not only is precise workpiece limiting achieved, but the position of the workpiece can also be flexibly adjusted, ensuring processing accuracy and efficiency.
[0039] Working Principle: When using this device, the workpiece is processed by the processing head 3. During the processing, when a large amount of heat is generated, the air is compressed by the air pump 7. The compressed air is then delivered to the connecting pipe 8 by the air pump 7 and ejected through the nozzle 9, rapidly cooling the equipment and preventing the workpiece and processing head 3 from overheating during operation. When position adjustment is needed, the operator pulls the handle 6, causing the sliding frame 5 to slide against the outer wall of the connecting frame 4, thus quickly adjusting the position of the cooling component. During processing, the device is electrically controlled... The output end of push rod 12 drives transmission rod 14 to slide on the outer wall of slide rail 13. The sliding of transmission rod 14 further causes clamping plate 15 to move inward synchronously. At the same time as transmission rod 14 moves, it also causes connecting rod 16 to deflect. The deflection of connecting rod 16 further drives rotating disk 17 to rotate in the opposite direction, thereby causing connecting rod 18 to slide synchronously on the outer wall of slide rail 20. This causes another clamping plate 15 to move inward synchronously in the opposite direction, so as to quickly limit the workpiece. At the same time, the position of the workpiece can also be adjusted so that the workpiece is always in the processing position.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
