Description

Technical Field

[0001] This utility model relates to the field of milling power head technology, specifically a high-speed precision milling power head. Background Technology

[0002] A high-speed precision milling power head is a high-precision, high-speed functional component used in CNC machine tools or machining centers, specifically designed for efficient and precise milling. It integrates the electric spindle, drive system, and control interface into a single, complete milling unit, reducing external dependencies. Currently, a cylindrical milling power head is inserted into a circular hole in an external mounting block, and secured with locking screws screwed onto the mounting block. Fastening the milling power head with locking screws only provides radial contact with the cylindrical power head. However, under long-term high-speed operation, this can cause axial movement of the power head, affecting milling accuracy. Therefore, a high-speed precision milling power head is needed to solve the above problems. Summary of the Invention

[0003] The purpose of this utility model is to provide a high-speed precision milling power head to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model is a high-speed precision milling power head, comprising: The brushless electric spindle is inserted into an external mounting block and secured with locking screws. The limiting assembly includes a support ring, a threaded hole, an adjusting rod, and a support plate. The support ring is fixed to the outside of the brushless electric spindle, the threaded hole is opened on the support ring, the adjusting rod is screwed into the threaded hole, and the support plate is rotatably connected to the upper end of the adjusting rod.

[0004] Furthermore, the limiting component also includes a fixing plate and a mounting hole. The fixing plate is welded to the inner side of the lower end of the support ring, and the mounting hole is opened in the middle of the fixing plate and fixed to the brushless electric spindle by screws.

[0005] Furthermore, the limiting component also includes a rubber block, which is fixed to the upper end of the support plate and fits against the lower end of the external mounting block.

[0006] Furthermore, there are three fixing plates and threaded holes, which are symmetrically distributed in a ring.

[0007] Furthermore, it also includes a damage prevention component, which includes an L-shaped connecting plate and an anti-slip pad. The L-shaped connecting plate is fixed to the upper end of the support ring, and the anti-slip pad is fixed to the side of the L-shaped connecting plate.

[0008] Furthermore, the damage prevention component also includes a first through hole and a second through hole. The first through hole is opened at one end of the L-shaped connecting plate, and the second through hole is opened on the support ring. The first through hole and the second through hole are fixed by bolts.

[0009] Furthermore, one side of the anti-slip pad is pressed against the outer side of the brushless electric spindle, and the side of the L-shaped connecting plate away from the anti-slip pad is pressed against the locking screw on the outer mounting block.

[0010] This utility model has the following beneficial effects: This invention, through the setting of a limiting component, places a support ring around the outside of the brushless electric spindle housing. Screws fix a fixing plate to the brushless electric spindle through the mounting holes. The brushless electric spindle is then inserted into the hole of the external mounting block, and the locking screw is tightened. Subsequently, the adjusting rod in the threaded hole is rotated, causing the support plate to move upward, which in turn causes the rubber block to abut against the lower end of the external mounting block. This design effectively limits the axial movement of the brushless electric spindle, avoids milling accuracy deviations caused by the original position offset, and significantly improves the stability of high-speed machining.

[0014] 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.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0016] Please see Figure 1-3 As shown, this utility model is a high-speed precision milling power head, comprising: The brushless electric spindle 10 is inserted into the external mounting block and fixed by locking screws; The brushless electric spindle model MSIY-6208 serves as the power core, integrating the electric spindle, drive system, and control interface to directly provide high-speed rotational power to drive the cutting tool or actuator to complete the machining task.

[0017] The limiting assembly includes a support ring 20, a threaded hole 23, an adjusting rod 24, and a support plate 25. The support ring 20 is fixed on the outside of the brushless electric spindle 10, the threaded hole 23 is opened on the support ring 20, the adjusting rod 24 is screwed into the threaded hole 23, and the support plate 25 is rotatably connected to the upper end of the adjusting rod 24. The limiting assembly also includes a fixing plate 21 and a mounting hole 22. The fixing plate 21 is welded to the inner side of the lower end of the support ring 20, and the mounting hole 22 is opened in the middle of the fixing plate 21 and is fixed to the brushless electric spindle 10 by screws. The limiting component also includes a rubber block 26, which is fixed to the upper end of the support plate 25 and fits against the lower end of the external mounting block. There are three fixing plates 21 and threaded holes 23, which are symmetrically distributed in a ring. The support ring 20 serves as the basic frame, fitted onto the outside of the electric spindle housing. It provides a mounting carrier for other limiting components such as the adjusting rod 24 and the fixing plate 21, and helps to limit the radial position of the electric spindle. The fixing plate 21 is welded to the inside of the support ring 20 and connected to the electric spindle body by screws through the mounting hole 22, rigidly fixing the entire limiting assembly to the electric spindle. The threaded hole 23 and the adjusting rod 24 form a helical pair, allowing for manual precision adjustment of the height. The support plate 25 is rotatably connected to the top of the adjusting rod 24 and rises and falls with the adjusting rod 24, transmitting thrust to the rubber block 26. The rubber block 26 is made of elastic material and fits against the lower end of the external mounting block. It absorbs gaps through compression deformation, achieving axial limiting and vibration reduction.

[0018] Working principle: The support ring 20 is fitted onto the outside of the brushless electric spindle 10 housing. The screws are used to fix the fixing plate 21 onto the brushless electric spindle 10 through the mounting hole 22. The brushless electric spindle 10 is inserted into the hole of the external mounting block, and the locking screws are tightened. Then, the adjusting rod 24 in the threaded hole 23 is rotated to move the support plate 25 upward, thereby causing the rubber block 26 to abut against the lower end of the external mounting block.

[0019] This step effectively limits the axial movement of the brushless electric spindle 10, avoids milling accuracy deviations caused by the original position offset, and significantly improves the stability of high-speed machining.

[0020] Please see Figure 3-4 As shown, this embodiment, based on the above embodiment, further includes: The damage prevention component includes an L-shaped connecting plate 30 and an anti-slip pad 32. The L-shaped connecting plate 30 is fixed to the upper end of the support ring 20, and the anti-slip pad 32 is fixed to the side of the L-shaped connecting plate 30. The damage prevention component also includes a first through hole 31 and a second through hole 33. The first through hole 31 is opened at one end of the L-shaped connecting plate 30, and the second through hole 33 is opened on the support ring 20. The first through hole 31 and the second through hole 33 are fixed by bolts. One side of the anti-slip pad 32 is pressed against the outside of the brushless electric spindle 10, and the side of the L-shaped connecting plate 30 away from the anti-slip pad 32 is pressed against the locking screw on the outer mounting block. The L-shaped connecting plate 30 is fixed to the upper end of the support ring 20. Its bending structure can span the gap between the electric spindle and the mounting block. The first through hole 31 and the second through hole 33 are fitted with bolts to achieve a rigid connection between the two. The anti-slip pad 32 undergoes elastic deformation after being pressed, filling the tiny gap between the two and preventing scratches on the surface of the electric spindle.

[0021] Working principle: Align the first through hole 31 on the L-shaped connecting plate 30 with the second through hole 33 on the support ring 20 and tighten with bolts. Fix the anti-slip pad 32 to the side of the L-shaped connecting plate 30. Slide the support ring 20 onto the brushless electric spindle 10 and fix it with screws so that the anti-slip pad 32 fits against the outside of the brushless electric spindle 10. Then insert the brushless electric spindle 10 and the L-shaped connecting plate 30 into the hole of the external mounting block, align the L-shaped connecting plate 30 with one end of the locking screw of the external mounting block, and tighten the locking screw so that it is firmly against the side of the L-shaped connecting plate 30. Under the pressure of the locking screw and the L-shaped connecting plate 30, the anti-slip pad 32 is pressed against the brushless electric spindle 10. When the L-shaped connecting plate 30 is worn after long-term use, it can be removed and replaced with a new one.

[0022] This step not only prevents the locking screw from directly contacting the surface of the brushless electric spindle 10 and causing scratches, but also buffers external impacts through elastic deformation, thus extending the service life of the equipment.
