Description

Technical Field

[0001] This utility model relates to the field of machine tool feet technology, specifically to an automatically adjustable machine tool foot. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier. After processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] CNC machine tools must be kept level when installed on the ground. Traditionally, the base of a CNC machine tool is adjusted using leveling bolts. During installation and commissioning, the level of the machine bed is primarily adjusted manually. However, these single locking bolts are easily loosened by vibrations during operation, causing a change in levelness. If the CNC machine tool does not meet the required level, it will cause malfunctions, affecting machining accuracy and lifespan. Furthermore, workers cannot immediately detect minor misalignments in traditional machine tools, resulting in the machine tool remaining tilted for extended periods, impacting the quality of machined parts.

[0004] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to this case. Summary of the Invention

[0005] The main purpose of this invention is to provide an automatically adjustable machine tool foot that adjusts promptly when the machine tool is tilted, ensuring that the machine tool always remains in a level position, with convenient operation and sensitive response.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] An automatically adjustable machine tool foot includes a base, a first level, a second level, a motor, a lead screw, a foot body, and a transmission assembly. The lower end of the base has several mounting cavities, and mounting brackets are provided on the sides of the mounting cavities. The motor is mounted on the mounting brackets. The lead screw passes through the bottom of the mounting cavity and is threaded to the bottom of the mounting cavity. The upper end of the foot body is connected to the lower end of the lead screw. The motor drives the lead screw to rotate through the transmission assembly. The first level is horizontally mounted on the base along the front-back direction, and the second level is horizontally mounted on the base along the left-right direction. The first level is electrically connected to the motor, and the second level is electrically connected to the motor.

[0008] Furthermore, the transmission assembly includes a first gear and a second gear. The first gear is mounted on the output shaft of the motor, and the second gear is mounted on the upper end of the lead screw. The first gear and the second gear mesh and transmit power.

[0009] Furthermore, the mounting bracket includes a horizontal plate and a vertical plate, which are arranged perpendicularly to each other. The vertical plate is mounted on the side wall of the base, the motor is mounted on the horizontal plate, and the vertical plate is provided with clearance holes.

[0010] Furthermore, the lower end of the lead screw is provided with a rounded corner, and the upper end of the foot body is provided with a mating groove that mates with the lower end of the lead screw.

[0011] Furthermore, the mounting bracket has six units.

[0012] Furthermore, the base has four mounting brackets at the front end and two mounting brackets at the rear end.

[0013] With the above structure, this new invention can monitor whether the base is tilted in real time through the first and second level instruments, ensuring that the machine tool base always remains in a horizontal state. When the base tilts, the first and second level instruments monitor the tilt direction and tilt angle of the base and send the signals to the central controller. The central controller then outputs signals to the motor that needs adjustment. The motor drives the lead screw to rotate, thereby adjusting the support height of the base and ensuring that the base can be restored to a horizontal state.

[0014] Compared with existing technologies, this invention can realize automated monitoring and adjustment of the base's levelness. It is not only simple to operate and highly responsive, but also has a simple structure that is easy to disassemble and maintain. Attached Figure Description

[0019] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0020] like Figure 1-3 As shown, an automatically adjustable machine tool foot includes a base 1, a first level 21, a second level 22, a motor 3, a lead screw 4, a foot body 5, and a transmission assembly. The lower end of the base 1 is provided with several mounting cavities 11, and the sides of the mounting cavities 11 are provided with mounting brackets 6. The motor 3 is mounted on the mounting brackets 6. The lead screw 4 passes through the bottom of the mounting cavity 11 and is threadedly connected to the bottom of the mounting cavity 11. The upper end of the foot body 5 abuts against the lower end of the lead screw 4. The motor 3 drives the lead screw 4 to rotate through the transmission assembly. The first level 21 is horizontally mounted on the base 1 along the front-back direction, and the second level 22 is horizontally mounted on the base 1 along the left-right direction. The first level 21 is electrically connected to the motor 3, and the second level 22 is electrically connected to the motor 3. The first level 21 monitors whether the base 1 is level in the front-to-back direction, and the second level 22 monitors whether the base 1 is level in the left-to-right direction. The first level 21 and the second level 22 can transmit the monitored signals to the central controller, which then controls each motor 3 to start. This is the traditional control method, and will not be elaborated further.

[0021] In this embodiment, the transmission assembly includes a first gear 71 and a second gear 72. The first gear 71 is mounted on the output shaft of the motor 3, and the second motor 3 is mounted on the upper end of the lead screw 4. The first gear 71 and the second gear 72 mesh and transmit power. The motor 3 drives the first gear 71 to rotate, which in turn drives the second gear 72 and the lead screw 4 to rotate, thereby driving the lead screw 4 to move up and down relative to the base 1.

[0022] In this embodiment, the mounting bracket 6 includes a horizontal plate 61 and a vertical plate 62, which are arranged perpendicularly to each other. The vertical plate 62 is mounted on the side wall of the base 1, and the motor 3 is mounted on the horizontal plate 61. The vertical plate 62 is provided with a clearance hole 63, which can provide clearance for the transmission component. With the above structure, the disassembly and maintenance of the motor 3 and the transmission component are more convenient and faster.

[0023] In this embodiment, the lower end of the lead screw 4 is rounded, and the upper end of the base body 5 is provided with a mating groove 51 that mates with the lower end of the lead screw 4. With this structure, the lower end of the lead screw 4 can adaptively adjust its relative position to the base body 5 during lifting, ensuring that the lower end of the lead screw 4 can stably engage within the mating groove 51 of the base body 5.

[0024] In this embodiment, there are six mounting brackets 6. Specifically, since the front end of the base 1 is relatively heavy, four mounting brackets 6 are provided at the front end of the base 1, and two mounting brackets 6 are provided at the rear end of the base 1.

[0025] With the above structure, this new invention can monitor whether the base 1 is tilted in real time through the first level 21 and the second level 22, ensuring that the base 1 of the machine tool is always kept in a horizontal state. When the base 1 is tilted, the first level 21 and the second level 22 will monitor the tilt direction and tilt angle of the base 1 and send the signal to the central controller. The central controller will then output a signal to the motor 3 that needs to be adjusted. The motor 3 drives the lead screw 4 to rotate, thereby adjusting the support height of the base 1 and ensuring that the base 1 can be restored to a horizontal state.

[0026] Compared with the prior art, this utility model can realize the automated monitoring and adjustment of the level of the base 1. It is not only simple to operate and highly responsive, but also simple in structure and easy to disassemble and maintain.

[0027] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
