Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a CNC machine tool that is easy to transport. Background Technology

[0002] CNC machine tools are flexible and high-efficiency automated machine tools that represent the development direction of modern machine tool control technology. Because they can better solve the problems of machining complex, precise, small-batch, and multi-variety parts, CNC machine tools are highly favored. The basic components of a CNC machine tool include a machining program carrier, a CNC device, a servo drive device, the machine tool body, and other auxiliary devices.

[0003] Because CNC machine tools are generally heavy, they are inconvenient to transport when they need to be moved due to the lack of a moving mechanism. Large machinery must be used to lift and transport them. This creates a problem: the factory where the CNC machine tool is placed must have enough space. Otherwise, large machinery cannot lift the CNC machine tool. Furthermore, it is difficult to lift the entire CNC machine tool at once, and it is easy for the CNC machine tool to rub against the ground, which can easily cause wear and tear.

[0023] 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.

[0024] Please see Figure 1-4 The present invention provides a CNC machine tool that is easy to transport, comprising a base frame 1 and a machine tool body 7, wherein multiple support components are symmetrically arranged at the bottom end of the base frame 1.

[0025] The upper end of the base frame 1 is provided with grooves 5 at the four corners of the base frame 1. The four corners of the bottom end of the machine tool body 7 are provided with vertical rods 6 inserted into the grooves 5. The middle part of the base frame 1 is provided with a center plate 8. The center plate 8 is provided with a slot 9. Two movable seats 13 are symmetrically and slidably arranged in the slot 9. A motor 10 is fixedly installed on one side of the base frame 1. The output end of the motor 10 is provided with a rotating shaft 11 inserted into the slot 9. Two screws 12 with reverse thread structure are symmetrically arranged on the rotating shaft 11. The two screws 12 pass through the two movable seats 13 respectively. The screws 12 are threadedly connected to the movable seats 13. Two support plates 14 are symmetrically arranged at the bottom end of the machine tool body 7. The top end of the support plate 14 is hinged to the machine tool body 7. The bottom end of the support plate 14 is hinged to the top end of the movable seat 13.

[0026] The lower end of the machine tool body 7 is provided with a plurality of second support rods 15, and the bottom end of the second support rods 15 is provided with bottom wheels 16.

[0027] In this embodiment, a plurality of locking rods 17 are provided at the four corners of the base frame 1. The locking rods 17 are threadedly connected to the base frame 1, and one end of the locking rods 17 contacts the vertical rod 6.

[0028] The machine tool body 7 is inserted into the grooves 5 at the four corners of the base frame 1 via the vertical rods 6 at the four corners of the bottom end, thus initially completing the positioning and connection between the two. The base frame 1 is placed on the ground by the support components symmetrically arranged at the four corners of its bottom end. In the support components, the base 2 is fixed to the lower end of the base frame 1, and the first support rod 3 is inserted into the base 2 and threadedly connected to it. By rotating the base block 4, the screw length of the first support rod 3 in the base 2 can be adjusted, thereby adjusting the height and level of the base frame 1 to ensure the stable placement of the machine tool. At the same time, the locking rods 17 at the four corners of the base frame 1 are threadedly connected to the base frame 1. After tightening, one end of the locking rod abuts against the vertical rod 6, enhancing the stability of the connection between the machine tool body 7 and the base frame 1.

[0029] After the motor 10 starts, the output shaft 11 rotates. Since the two screws 12 on the shaft 11 have a reverse thread structure and the screws 12 pass through and are threadedly connected to the movable seats 13 in the slot 9, when the shaft 11 rotates, the two movable seats 13 will move in opposite directions or in opposite directions along the slot 9 under the drive of the screws 12 through the principle of the thread structure. The support plates 14 are symmetrically arranged at the bottom of the machine tool body 7. The top end of the support plates 14 is hinged to the machine tool body 7, and the bottom end is hinged to the top end of the movable seats 13. Before the movable seats 13 move in opposite directions, the locking rod 17 is released. When the movable seats 13 move in opposite directions, the support plates 14 will pull the machine tool body 7 down; when the movable seats 13 move in opposite directions, the support plates 14 will push the machine tool body 7 up.

[0030] The lower end of the machine tool body 7 is provided with a second support rod 15 with a bottom wheel 16. When the machine tool body 7 is lowered to a certain height, the bottom wheel 16 contacts the ground and bears part of the weight of the machine tool. At this time, the bottom block 4 of the support component can be raised appropriately, so that the bottom block 4 is lifted off the ground by a certain distance. The rolling of the bottom wheel 16 realizes the convenient transportation of the CNC machine tool. When the machine tool body 7 is in use, the bottom wheel 16 is lifted off the ground, so that the bottom block 4 contacts the ground, and then the locking rod 17 is locked.

[0031] In this embodiment, multiple support components are located at the four corners of the base frame 1. Each support component includes a base 2, a first support rod 3, and a base block 4. The base block 4 is fixed to the lower end of the first support rod 3. The base 2 is fixed to the lower end of the base frame 1. The first support rod 3 is inserted into the interior of the base 2 and threadedly connected to the base 2.

[0032] Place the base frame 1 in the predetermined position, and rotate the base block 4 by moving the toggle blocks on both sides of the base block 4 to adjust the height of the support assembly so that the base frame 1 is in a horizontal state.

[0033] Lift the machine tool body 7, align the vertical rods 6 at the four corners of its bottom end with the grooves 5 of the base frame 1 and insert them.

[0034] Rotate the locking rods 17 at the four corners of the base frame 1 so that one end of them contacts the vertical rod 6 and tightens them to fix the machine tool body 7 and the base frame 1.

[0035] Loosen the locking lever 17, start the motor 10, and make the motor 10 drive the rotating shaft 11 to rotate, causing the two moving seats 13 to move towards each other. The support plate 14 pulls the machine tool body 7 down until the bottom wheel 16 contacts the ground and supports part of the machine tool weight.

[0036] Move the levers on both sides of the base block 4 again to raise the base block 4 of the support assembly, so that the base block 4 is properly lifted off the ground.

[0037] Push or pull the CNC machine tool and use the rolling of the bottom wheel 16 to transport it to the designated position.

[0038] After transporting the CNC machine tool to its destination, start the motor 10 to reverse, causing the moving seat 13 to move in opposite directions. The machine tool body 7 rises, the bottom wheel 16 leaves the ground, and the bottom block 4 of the support assembly contacts the ground to support the machine tool. Then, lock the locking rod 17.

[0039] The CNC machine tool is driven by motor 10 to lift the machine tool body 7, so that the bottom wheel 16 can contact the ground to assist in transportation. It does not require large hoisting machinery, which reduces the requirements for transportation space and reduces the difficulties and costs in the transportation process. Even in a factory with limited space, the CNC machine tool can be moved easily.

[0040] The base frame 1 is connected to the machine tool body 7 through the cooperation of the groove 5, the vertical rod 6 and the locking rod 17. The support assembly can adjust the height and level, ensuring the stability of the machine tool during use. At the same time, when the machine tool is working, the bottom wheel 16 does not bear the main support force, avoiding the impact of the bottom wheel 16 on the stability of the machine tool and ensuring machining accuracy.

[0041] In this embodiment, the bottom block 4 is provided with toggle blocks on both sides, which makes the bottom block 4 easy to operate.

[0042] In this embodiment, the motor 10 is a servo motor.

[0043] The toggle block design of the support component base block 4 makes it easy for operators to adjust the height of the support component. The motor 10 adopts a servo motor 10, which can accurately control the lifting height of the machine tool body 7. The operation process is simple and flexible, reducing the labor intensity of operators.
