Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool processing technology, and specifically to a CNC machine tool processing worktable. Background Technology

[0002] In automated CNC machining, the parts to be processed are typically pre-fixed on a pallet, and then a robot clamps the pallet onto a fixed seat on the machine tool's worktable for positioning. Due to structural limitations, the support area of ​​a traditional fixed seat is much smaller than the size of the pallet. When the pallet area is significantly larger than the fixed seat, the edges of the pallet become suspended due to a lack of effective support. Under the influence of the workpiece and machining vibrations, the pallet is prone to slight tilting around the fixed seat's fulcrum, compromising the original positioning accuracy of the workpiece and causing tilting deviations. Therefore, there is an urgent need for a workbench structure that combines wide-range support stability with multi-directional adjustment capabilities. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a CNC machine tool processing worktable that eliminates pallet tilting through multi-point collaborative support; achieves multi-degree-of-freedom orientation adjustment of the support components; and improves adaptability to pallets of different sizes.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A CNC machine tool machining worktable includes a support platform and a fixed base fixedly disposed on the upper part of the support platform. Several auxiliary support components are movably disposed on the upper part of the support platform. The auxiliary support components are distributed around the fixed base, and the auxiliary support components and the fixed base together constitute a horizontal support structure for fixing a support plate.

[0005] Furthermore, the number of auxiliary support components is four, which are respectively set at the four right-angle positions of the fixed base.

[0006] Furthermore, elongated through slots are provided at the four right-angle positions of the fixed base, and the auxiliary support assembly passes through the elongated through slots and is connected to the support platform.

[0007] Furthermore, the auxiliary support assembly includes a fixed rod, a swing rod, and a support column; the fixed rod is fixedly installed on the upper part of the support platform; the support column is movably disposed on the upper part of the support platform; one end of the swing rod is sleeved on the fixed rod, and the other end is sleeved on the support column, driving the support column to move circumferentially around the fixed rod.

[0008] Furthermore, the fixing rod has a T-shaped structure, including an integrally formed rod portion one and a boss portion one; the rod portion one passes through an elongated through groove, and the size of the boss portion one is larger than the width of the elongated through groove; the fixing seat fixes the boss portion one by pressing the periphery of the elongated through groove.

[0009] Furthermore, the support column has a T-shaped structure, including an integrally formed rod portion two and a boss portion two; the lower surface of the end of the swing rod that is sleeved with the support column is provided with circumferentially distributed protrusions, and the protrusions form point contact with the upper surface of the boss portion two of the support column.

[0010] Compared with existing technologies, the technical solution of this patent has the following advantages: The four-corner auxiliary support components and the fixed base form a support system, completely eliminating tilting caused by the pallet's edge being suspended, correcting the pallet's balance, and significantly improving positioning stability. The auxiliary support components can be adjusted vertically according to actual processing needs. The elongated through-slots form a moving guide rail, allowing the auxiliary support components to be adjusted vertically along the guide rail, dynamically adapting to pallets of different areas and improving versatility. In addition, the support column can swing circumferentially around the fixed rod. This design achieves multi-degree-of-freedom spatial position adjustment of the support column: it can adapt to uneven bottom surfaces of the pallet by swinging, and can be quickly installed during debugging, greatly simplifying the installation process.

[0013] 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.

[0014] See Figure 1-6 As shown, this embodiment provides a CNC machine tool machining table, including a support platform 1 and a fixed base 2 fixedly disposed on the upper part of the support platform. The fixed base 2 includes a pneumatically driven assembly part 22, which is used to lock and fix the pallet 3 on its upper part. The pneumatically driven assembly part 22 is a conventional technology, and its structure will not be further described in this article. Several auxiliary support components 4 are movably disposed on the upper part of the support platform 1. The auxiliary support components 4 are distributed around the fixed base 2, and the auxiliary support components 4 and the fixed base 2 together constitute a support structure for fixing the pallet 3. By setting movable auxiliary support components 4 around the fixed base 2, a multi-point horizontal support structure is formed together with the fixed base 2, effectively expanding the support range for the large-area pallet 3. This design fundamentally solves the tilting problem caused by the pallet 3 having a much larger area than the fixed base 2, significantly improving positioning stability; at the same time, the movable setting characteristics of the support components provide a structural basis for subsequent angle adjustment.

[0015] See Figure 1-4 As shown, there are four auxiliary support components 4, which are respectively set at the four right-angle positions of the fixed base 2. The four auxiliary support components 4 are precisely arranged at the four corners of the fixed base 2 to form a symmetrical force system. This structure makes full use of the principle of geometric stability, providing direct support in the right-angle area where the pallet 3 is most prone to overturning, specifically resisting the off-center load moment, preventing the pallet 2 from tilting slightly due to local suspension, and ensuring positioning accuracy.

[0016] The fixed base 2 has elongated slots 21 at each of its four right-angled positions. The auxiliary support component 4 passes through the elongated slots 21 and connects to the support platform 1. By designing the slots as elongated structures, the auxiliary support component 4 can be adjusted vertically according to actual processing requirements. This is equivalent to the elongated slots 21 forming a moving guide rail, allowing the auxiliary support component 4 to be adjusted vertically along the guide rail. This dynamically adapts to pallets of different areas, improving versatility.

[0017] See Figure 5-6 As shown, the auxiliary support assembly 4 includes a fixed rod 41, a swing rod 42, and a support column 43. The fixed rod 41 is fixedly installed on the upper part of the support platform 1. The support column 43 is movably installed on the upper part of the support platform 1. One end of the swing rod 42 is sleeved on the fixed rod 41, and the other end is sleeved on the support column 43, driving the support column 43 to move circumferentially around the fixed rod 41. The swing rod 42, in conjunction with the hinged structure of the fixed rod 41 and the support column 43, allows the support column 43 to swing circumferentially around the fixed rod 41. This design achieves multi-degree-of-freedom spatial position adjustment of the support column 43: it can adapt to uneven bottom surfaces of the support plate through swinging, and it can be quickly installed during debugging, greatly simplifying the installation process.

[0018] The fixing rod 41 has a T-shaped structure, including an integrally formed rod portion 411 and a boss portion 412. The rod portion 411 passes through the elongated through groove 21, and the size of the boss portion 412 is larger than the width of the elongated through groove 21. The fixing seat 2 presses the boss portion 412 against the periphery of the elongated through groove 21. The periphery of the through groove 21 of the fixing seat 2 presses the boss portion 412 downward, generating a continuous preload force to resist loosening caused by processing vibration.

[0019] The support column 43 has a T-shaped structure, including an integrally formed rod portion 431 and a boss portion 432. The lower surface of the end of the swing rod 42 that fits into the support column 43 is provided with circumferentially distributed protrusions 421, which form a point contact structure with the upper surface of the boss portion 432 of the support column 43. By replacing surface contact with point contact, the relative friction area between the swing rod 42 and the support column 43 is reduced. The circumferentially distributed protrusions 421 constitute a multi-point balance, ensuring that the swing rod 42 and the boss portion 432 of the support column 43 are always subjected to uniform force, avoiding skewness.

[0020] During processing, the robotic arm clamps the pallet 3 onto the fixed seat 2 of the machine tool table for positioning, where it is supported by the central fixed seat 2 and the surrounding auxiliary support components 4. The four corner support columns 43 precisely abut against the easily tipping areas of the pallet 3. It should be noted that the workpiece to be processed is fixed onto the pallet 3 in advance, and a fixture 5 connected to the robotic arm is installed on one side of the pallet 3. When the position of the auxiliary support components 4 needs to be adjusted, the auxiliary support components 4 move up and down along the elongated through groove 21 of the fixed seat; in addition, the support columns 43 can be rotated around the axis of the fixed rod 41 by swinging the swing rod 42, so that the support columns 43 precisely abut against the easily tipping areas of the pallet 3. The four corner auxiliary support components 4 and the fixed seat 2 form a support system, completely eliminating the tilting caused by the edge of the pallet 3 being suspended, and significantly improving the positioning stability.
