Description

Technical Field

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

[0002] CNC machine tools are the core automated processing equipment in modern manufacturing. They control the relative movement of the cutting tool and the workpiece through CNC system programming. They integrate the host machine, drive device, detection feedback system and auxiliary mechanism, and have the characteristics of high precision, high efficiency and high stability. They can accurately process complex curved surfaces, hole systems, groove systems and other structures. They are suitable for single-piece or batch production and are widely used in the automotive, aerospace, mold and other fields. They can greatly reduce the dependence on manual labor and ensure the consistency of processing. They are key equipment for realizing precision manufacturing.

[0003] For example, utility model patent CN220993494U discloses a CNC machine tool handling base, including a base with an internal placement groove for mounting the machine tool. Universal wheels are symmetrically fixed to both sides of the base's bottom. The base also has a fixing mechanism, including a telescopic groove located inside the base. A cylinder is fixedly connected inside the telescopic groove. This CNC machine tool handling base eliminates the need for manual handling, ensuring the safety of the machine tool during transport and protecting workers from injury. It also eliminates the need for forklifts or other engineering vehicles, saving time and improving efficiency. The structure is simple and the operation is easy.

[0004] However, this type of base has the following drawbacks:

[0005] It is only suitable for moving on flat ground and cannot cope with complex road conditions such as steps; the load-bearing structure is simple (only two sets of universal wheels), the load-bearing capacity is limited, and the stability is poor when moving.

[0006] The machine tool is fixed only by the mounting slot, without lateral limiting and buffer structures, making it easy to slide and bump during transportation, and there is no anti-slip design on the bottom;

[0007] The support has poor stability, relying solely on a single point of support column at the bottom for bearing, and lacks a leveling function, making it prone to tilting when left static for a long time; the support structure has insufficient strength, and the concentrated stress makes it prone to deformation.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] Please see Figures 1-4 A CNC machine tool transport base, comprising:

[0034] The frame 1 has four adjustable arms 6 that can extend outwards slidably on its four side walls;

[0035] Hydraulic working module 2 is fixedly installed at the bottom of the frame 1. Hydraulic working module 2 is connected to adjusting cylinder 3, load-bearing cylinder 5 and support cylinder 9 by oil pipes.

[0036] The support platform 8 is fixedly installed at the end of the adjusting arm 6, the support cylinder 9 is fixedly installed on the lower wall of the support platform 8, and the lower end of the support cylinder 9 is fixedly installed with a load-bearing caster wheel 10.

[0037] Adjusting cylinder 3 is located below each adjusting arm 6 and is fixedly connected to the side wall of the housing of the hydraulic working module 2. A connecting block 7 is fixedly installed on the lower wall of the adjusting arm 6, and the telescopic end of the adjusting cylinder 3 is fixedly connected to the connecting block 7.

[0038] The load-bearing hydraulic cylinder 5 is set vertically. A through hole is opened at the center of the frame 1. The load-bearing hydraulic cylinder 5 passes through the through hole and is fixed on the housing of the hydraulic working module 2. The lifting end of the load-bearing hydraulic cylinder 5 is fixedly installed with a load-bearing platform 4.

[0039] In use, the frame 1 provides the basic installation carrier and overall load-bearing support for the entire transport base; the hydraulic working module 2 provides hydraulic power to the adjusting cylinder 3, the load-bearing cylinder 5, and the support cylinder 9, realizing the action control of each component; the adjusting cylinder 3 drives the connecting block 7 and the adjusting arm 6 to slide through hydraulic drive, adjusting the position of the support platform 8; the load-bearing platform 4 directly supports the CNC machine tool body and transmits the weight of the machine tool; the load-bearing cylinder 5 controls the lifting and lowering through an independent hydraulic oil circuit, adjusting the height of the support platform 4 to adapt to the placement or transport needs of the machine tool; the four adjusting arms 6 drive the support platform 8 and auxiliary components to move synchronously, expanding the support range; the connecting block 7 realizes the fixed connection between the adjusting arm 6 and the driving end of the adjusting cylinder 3, transmitting the driving force; the support platform 8 provides the installation foundation for the support cylinder 9, the pressure distribution platform 11, and other components, assisting in bearing the weight of the machine tool; the support cylinder 9 realizes the lifting and lowering through independent hydraulic control, adjusting the support height of the load-bearing caster 10; the load-bearing caster 10 realizes the flexible movement and steering of the transport base, facilitating the position adjustment of the CNC machine tool.

[0040] Please see Figure 3 Pressure dividing platforms 11 are fixedly installed on both the left and right sides of the support platform 8; several reinforcing ribs 12 are fixedly installed at the right-angle connection between the pressure dividing platform 11 and the support platform 8; an elastic support pad 13 is fixedly installed on the wall of the support platform 8 facing the frame 1, and the elastic support pad 13 is in contact with the side wall of the CNC machine tool.

[0041] In use, the pressure-reducing platform 11 shares the load-bearing pressure of the support platform 8, expands the support contact area, and improves the support stability; several reinforcing ribs 12 enhance the structural strength of the connection between the pressure-reducing platform 11 and the support platform 8, and prevent deformation under stress; the elastic support pad 13 buffers the collision impact between the CNC machine tool and the support platform 8, while preventing the machine tool sidewall from being scratched, and enhancing the fit stability.

[0042] Please see Figure 3 A load-bearing screw 14 is vertically fixedly installed on the lower wall of the pressure distribution table 11; a load-bearing screw sleeve 15 is threaded onto the outer wall of the load-bearing screw 14; and a support anti-slip pad 16 is fixedly installed on the lower wall of the load-bearing screw sleeve 15.

[0043] In use, the load-bearing screw 14 and the load-bearing sleeve 15 are connected by threads to achieve fine adjustment of the support height; the load-bearing sleeve 15 is adjusted by rotating to adjust the contact height with the ground to assist in leveling and at the same time share the load-bearing capacity of the support platform 8; the support anti-slip pad 16 increases the friction between the load-bearing sleeve 15 and the ground to prevent the transport base from sliding and at the same time plays a buffering role.

[0044] Please see Figure 3 The outer wall surface of the load-bearing screw sleeve 15 is evenly provided with several anti-slip textures 17 along the circumference, and the anti-slip textures 17 extend along the axial direction of the load-bearing screw sleeve 15.

[0045] During use, the anti-slip texture 17 increases the friction between the hand and the outer wall of the load-bearing screw sleeve 15, making it easier for the operator to rotate and adjust the load-bearing screw sleeve 15 and improving the ease of operation.

[0046] Please see Figure 4 The hydraulic working module 2 is rotatably connected to the lower wall of the four adjusting arms 6. A horizontal load-bearing shaft 19 is fixedly installed on both sides of the load-bearing shaft 18. A load-bearing wheel 20 is rotatably connected to the load-bearing shaft 19, and the outer wall of the load-bearing wheel 20 is provided with a wear-resistant rubber layer 21.

[0047] In use, the transport frame 18 provides mounting support for the load-bearing shaft 19 and the load-bearing wheels 20; the load-bearing shaft 19 provides rotational support for the load-bearing wheels 20 to ensure their stable rolling; the load-bearing wheels 20, together with the load-bearing casters 10, enable the overall movement of the transport base and share the load-bearing weight; the wear-resistant rubber layer 21 enhances the wear resistance and cushioning performance of the load-bearing wheels 20, reduces noise during movement, and protects the ground.

[0048] Please see Figure 4 The load-bearing wheels 20 are set in multiple groups, and each group is distributed along the left and right sides of the transport frame 18. Each group of load-bearing wheels 20 is symmetrically set at both ends of the load-bearing shaft 19.

[0049] During use, multiple evenly distributed load-bearing wheels 20 make the weight distribution more even, improve the load-bearing stability of the transport base, and avoid excessive local stress; each symmetrically arranged load-bearing wheel 20 enhances the balance during movement and prevents tilting.

[0050] Please see Figure 2 A load-bearing anti-slip pad 22 is fixedly installed on the upper wall of the load-bearing platform 4, and the area of ​​the load-bearing anti-slip pad 22 is adapted to the area of ​​the upper wall of the load-bearing platform 4.

[0051] When in use, the load-bearing anti-slip pad 22 increases the friction between the CNC machine tool and the load-bearing table 4, preventing the machine tool from sliding during handling or when stationary, while also protecting the bottom of the machine tool from wear.

[0052] By alternating extension and retraction of the support cylinder, adjusting the position of the adjusting arm 6 and coordinating with the load-bearing wheels 20, the transport base can smoothly ascend stairs and other complex road conditions, adapting to the machine tool transport needs of different height areas in the workshop.

[0053] Specifically, when climbing stairs, the operator pushes the machine tool's frame 1 to the edge of the step, activates the hydraulic working module 2, and first controls the four support cylinders 9 to extend synchronously, raising the frame 1 so that the load-bearing wheels 20 are off the ground. Then, the front single-side support cylinder 9 is adjusted to retract to match the height of the step, pushing the frame 1 forward so that the load-bearing caster 10 on that side accurately lands on the step surface. At this time, the corresponding load-bearing wheel 20 (with a wear-resistant rubber layer 21) simultaneously fits into the step surface, forming a stable fulcrum.

[0054] Repeat the above actions, retracting the other front support cylinder 9 to the step height, and continue moving the frame 1 forward until both sets of front load-bearing casters 10 and load-bearing wheels 20 are stably supported on the step. Then, following the same logic, alternately retract the rear support cylinder 9, gradually moving the rear load-bearing casters 10 and load-bearing wheels 20 to the step surface, completing the overall step ascent. During this process, the load-bearing anti-slip pad 22 on the load-bearing platform 4 increases friction to prevent the machine tool from sliding; the elastic support pad 13 on the inner wall of the support platform 8 buffers the step-ascent vibration, protecting the machine tool's accuracy. After step ascent, rotate the load-bearing screw sleeve 15 under the pressure distribution platform 11 (the outer wall anti-slip texture 17 facilitates gripping and operation), and finely adjust the height using the load-bearing screw 14 to ensure the support anti-slip pad 16 is evenly attached to the ground, completing leveling and fixing, and preventing uneven force on the machine tool.

[0055] By adjusting the height of the load-bearing hydraulic cylinder 5, precisely aligning the adjusting arm 6, and finely adjusting the load-bearing screw sleeve 15, the CNC machine tool can be accurately placed and stably supported for a long time, adapting to the needs of machine tool installation, debugging, and long-term static placement scenarios.

[0056] Specifically, during transport, the hydraulic working module 2 controls the extension of the adjusting cylinder 3, which drives the support platform 8, under the action of the load-bearing casters 10, to extend the four adjusting arms 6 to their maximum stroke. The operator then moves the machine tool onto the load-bearing anti-slip mat 22, activates the load-bearing cylinder 5 to lower the support platform 4, and once lowered to the appropriate position, the operator controls the adjusting cylinder 3 to retract until the elastic support mat 13 is tightly against the side wall of the machine tool. At this point, the machine tool can be moved smoothly. When moved to the target location, if the machine tool needs to work there for an extended period, it can be unloaded from the frame 1. For temporary work, the load-bearing sleeve 15 can be rotated, and the support height of the pressure-distributing platform 11 can be finely adjusted via the load-bearing screw 14, ensuring the support anti-slip mat 16 is evenly pressed against the ground, further distributing the weight and leveling the base. Multiple sets of load-bearing wheels 20 and the load-bearing casters 10 work together to ensure the machine tool remains stable even when stationary or under slight vibration.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
