Description

Technical Field

[0001] This utility model relates to a large spindle support frame. Background Technology

[0002] In modern machining, the CNC spindle, as a core power component, directly determines machining accuracy and efficiency. Large CNC spindles mounted on a machine frame, needing to drive large-diameter tools or bear heavy workpieces, often have greater size and weight, generating continuous radial, axial, and vibration loads during operation. This characteristic places stringent requirements on the support structure. A stable support must not only bear the static load of the spindle itself but also effectively suppress dynamic chatter during high-speed operation, preventing insufficient support rigidity from exacerbating machining errors or even causing equipment failure. Summary of the Invention

[0003] In order to improve the support stability of the main spindle support frame, this utility model provides a main spindle support frame.

[0004] This utility model provides a technical solution that adopts the following approach: A large spindle support frame includes a mounting base and an adjusting base. A connecting member is provided between the mounting base and the adjusting base, and the mounting base and the adjusting base are slidably connected by the connecting member. The adjusting base includes multiple guide rails, and the mounting base is provided with multiple locking blocks corresponding to the guide rails. The locking blocks are engaged and slidably engaged with the guide rails. The mounting base is provided with several horizontal and vertical reinforcing ribs, and the mounting base has mounting holes for inserting a large spindle.

[0005] The drive unit of the main spindle is placed outside the support frame, and the main spindle is mounted on the mounting base. The position of the mounting base on the adjusting seat is adjusted so that the main spindle can be positioned at a suitable height for product processing. Several horizontal and vertical reinforcing ribs are provided on the peripheral wall of the mounting base used to mount the main spindle. This increases the overall strength of the support frame in multiple dimensions, reduces deformation of the mounting base due to the weight of the main spindle, and enhances the installation stability of the main spindle, reducing wobbling during operation and improving work efficiency.

[0006] Preferably, the mounting base has extension plates on both sides, and multiple clips are disposed on the back of the two extension plates. The horizontal reinforcing ribs and vertical reinforcing ribs are disposed between the extension plates and the side wall of the mounting base.

[0007] The mounting base has extension plates on both sides, with the locking block placed on the back of the extension plates. Reinforcing ribs are placed between the extension plates and the side wall of the mounting base. The extension plates expand the force-bearing surface of the locking block, and the reinforcing ribs strengthen the connection between the two, dispersing the load transmitted by the guide rail, reducing the deformation of the mounting base caused by uneven force, and improving the stability during sliding adjustment.

[0008] Preferably, the horizontal reinforcing ribs are disposed on both sides of the mounting base and are evenly distributed along the height direction of the mounting base. The two ends of the vertical reinforcing ribs are connected to adjacent horizontal reinforcing ribs, and the two sides of the vertical reinforcing ribs are respectively connected to the outer periphery of the mounting base and the side wall of the horizontal reinforcing ribs away from the mounting base.

[0009] Horizontal reinforcing ribs are evenly distributed along the height on both sides of the mounting base. Vertical reinforcing ribs connect adjacent horizontal ribs and connect the outer periphery of the mounting base to the outer side of the horizontal ribs, forming a grid-like reinforcing structure. This disperses the stress from multiple directions, significantly improving the mounting base's resistance to deformation and making the stress distribution more uniform, further enhancing the stability of the main spindle installation.

[0010] Preferably, both the horizontal and vertical reinforcing ribs are plate-shaped, and the sidewall of the mounting base, the horizontal reinforcing ribs, and the vertical reinforcing ribs are all perforated with heat dissipation holes.

[0011] The horizontal and vertical reinforcing ribs are designed as plates, and heat dissipation holes are drilled through the side wall of the mounting base and the ribs. The plate structure strengthens the support strength, and the heat dissipation holes accelerate the heat dissipation of the main spindle during operation, reducing the impact of thermal deformation and balancing structural stability and heat dissipation performance.

[0012] Preferably, the connecting component includes a drive motor, a lead screw, and a slider. The slider is fixedly connected to the back side of the mounting base, and the slider is threadedly connected to the lead screw. The slider is block-shaped, and the adjusting base has a movable groove for the slider to move.

[0013] The movable groove not only provides clearance for the slider's movement, but also reserves heat dissipation space between the mounting base and the adjustment base, reducing heat accumulation in the middle of the main spindle.

[0014] In summary, this utility model has the following beneficial technical effects: The drive unit of the main spindle is placed outside the support frame, and the main spindle is mounted on the mounting base. The position of the mounting base on the adjusting seat is adjusted so that the main spindle can be positioned at a suitable height for product processing. Several horizontal and vertical reinforcing ribs are provided on the peripheral wall of the mounting base used to mount the main spindle. This increases the overall strength of the support frame in multiple dimensions, reduces deformation of the mounting base due to the weight of the main spindle, and enhances the installation stability of the main spindle, reducing wobbling during operation and improving work efficiency.

[0018] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0019] This utility model discloses a large spindle support frame.

[0020] Reference Figure 1 A large spindle support frame includes a mounting base 1 and an adjusting base 2. A connecting member is provided between the mounting base 1 and the adjusting base 2. The mounting base 1 and the adjusting base 2 are slidably connected by the connecting member. The adjusting base 2 includes multiple guide rails 4. The mounting base 1 is provided with multiple locking blocks 3 corresponding to the guide rails 4. The locking blocks 3 are engaged and slidably connected to the guide rails 4. The mounting base 1 is provided with several horizontal reinforcing ribs 5 and vertical reinforcing ribs 6. The mounting base 1 has mounting holes for inserting a large spindle 7.

[0021] The drive unit of the main spindle 7 is placed outside the support frame, and the main spindle 7 is mounted on the mounting base 1. The position of the mounting base 1 on the adjusting base 2 is adjusted so that the main spindle 7 can be in a suitable height position for product processing. Several horizontal reinforcing ribs 5 and vertical reinforcing ribs 6 are provided on the peripheral wall of the mounting base 1 used to mount the main spindle 7. This can increase the overall strength of the support frame in multiple dimensions, reduce the deformation of the mounting base 1 caused by the gravity of the main spindle 7, and the stable mounting base 1 can enhance the installation stability of the main spindle 7, reduce the shaking of the main spindle 7 during operation, and improve the working efficiency.

[0022] Reference Figure 1 as well as Figure 2 In this embodiment, the mounting base 1 has extension plates 8 on both sides, and multiple clips 3 are disposed on the back side of the two extension plates 8. Horizontal reinforcing ribs 5 and vertical reinforcing ribs 6 are disposed between the extension plates 8 and the side wall of the mounting base 1.

[0023] The mounting base 1 has extension plates 8 on both sides, and the locking block 3 is placed on the back side of the extension plate 8. The reinforcing rib is located between the extension plate 8 and the side wall of the mounting base 1. The extension plate 8 expands the force-receiving surface of the locking block, and the reinforcing rib strengthens the connection between the two, disperses the load transmitted by the guide rail 4, reduces the deformation of the mounting base 1 caused by uneven force, and improves the stability during sliding adjustment.

[0024] Reference Figure 1 as well as Figure 2In this embodiment, the horizontal reinforcing ribs 5 are distributed on both sides of the mounting base 1. The horizontal reinforcing ribs 5 are evenly distributed along the height direction of the mounting base 1. The two ends of the vertical reinforcing ribs 6 are connected to the adjacent horizontal reinforcing ribs 5. The two sides of the vertical reinforcing ribs 6 are respectively connected to the outer periphery of the mounting base 1 and the side wall of the horizontal reinforcing ribs 5 away from the mounting base 1.

[0025] The horizontal reinforcing ribs 5 are evenly distributed along the height on both sides of the mounting base 1. The vertical reinforcing ribs 6 connect the adjacent horizontal reinforcing ribs 5 and connect the outer periphery of the mounting base 1 to the outer side of the horizontal reinforcing ribs 5 respectively, forming a grid-like reinforcing structure. This disperses the force from multiple directions, greatly improving the deformation resistance of the mounting base 1, while making the stress distribution more uniform and further enhancing the installation stability of the main spindle 7.

[0026] Reference Figure 1 as well as Figure 2 In this embodiment, both the horizontal reinforcing rib 5 and the vertical reinforcing rib 6 are plate-shaped, and heat dissipation holes 9 are penetrating the side wall of the mounting base 1, the horizontal reinforcing rib 5, and the vertical reinforcing rib 6.

[0027] The horizontal reinforcing ribs 5 and vertical reinforcing ribs 6 are plate-shaped, and heat dissipation holes 9 are passed through the side wall of the mounting base 1 and the ribs. The plate-shaped structure strengthens the support strength, and the heat dissipation holes 9 accelerate the heat dissipation of the main spindle 7 during operation, reducing the impact of thermal deformation and taking into account both structural stability and heat dissipation performance.

[0028] Reference Figure 1 as well as Figure 2 In this embodiment, the connecting component includes a drive motor 10, a lead screw 11, and a slider. The slider is fixedly connected to the back side of the mounting base 1 and threadedly connected to the lead screw 11. The slider is square-shaped, and the adjusting base 2 has a movable groove 12 for the slider to move.

[0029] The movable groove 12 not only provides clearance for the slider's movement, but also reserves heat dissipation space between the mounting base 1 and the adjusting base 2, reducing the heat accumulation of the large spindle 7 in the middle of the mounting base 1.

[0030] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
