Description

Technical Field

[0002] CNC machine tools are highly efficient, accurate and automated processing equipment that uses a numerical control system to control the movement of machining cutters or tools on the workpiece, thereby achieving precise processing of the workpiece. CNC machine tools can process a wide range of objects, including various metal and non-metal materials, such as steel, iron, aluminum, copper, plastic, etc.

[0003] The base of a CNC machine tool is an important part of the CNC machine tool. It is the foundation and support part of the machine tool, bearing the entire weight of the machine tool and various forces during processing. The main structural components of the base include the base longitudinal beam, base plate, support, Nanping nut and fastening screws. The material and manufacturing process of the base have an important influence on the overall performance of the machine tool. It is usually made of high-strength and high-rigidity materials to ensure the stability and precision of the machine tool.

[0004] After searching, the Chinese patent number CN214322503U discloses a CNC machine tool base with adjustable level; Compared with the prior art, the Chinese patent number CN214322503U can easily drive the machine tool to rotate at a certain angle, thereby facilitating the adjustment of the horizontal angle of the machine tool and is easy to operate.

[0005] However, in actual use, the above device directly adjusts the angle of the base by rotating the turntable. However, the angle of the base needs to be repeatedly adjusted until the base is kept in a horizontal state. The accuracy of the adjustment is low. Moreover, when the base is used after being adjusted to a horizontal state, if the base has an abnormal angle due to external factors and is not discovered in time, it is easy to affect the operation of the CNC machine tool. Therefore, a CNC machine tool base for mechanical processing is proposed, which is convenient for quickly and accurately adjusting the base to a target state and monitoring the state of the base in real time. Summary of the invention

[0006] The purpose of the present invention is to facilitate the rapid and accurate adjustment of the base to a target state and to monitor the state of the base in real time, and to propose a CNC machine tool base for mechanical processing.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1 like Figure 1-6 As shown, a CNC machine tool base for mechanical processing proposed by the present invention comprises a support seat 7 and a base 8, an adjustment box 9 is installed on one side of the support seat 7 located at the base 8, and the adjustment box 9 is movably connected to the base 8, and a precise component for adjusting the horizontal state of the base 8 is arranged outside the adjustment box 9, and the precise component comprises an indicator needle 13 arranged on the adjustment box 9, and a limit rod 16 arranged on the adjustment box 9 for limiting the indicator needle 13, and a limit plate 20 for the base 8 is symmetrically and movably connected on both sides of the support seat 7 and between the support seat 7 and the base 8; A monitoring system for the base 8 is provided outside the base 8, and the monitoring system includes: The sensor module 1 is used to capture the horizontal state information of the base 8 in real time; The data acquisition module 2 is used to convert the electrical signal output by the sensor module 1 into digital data; Data transmission module 3, used to ensure real-time and accurate transmission of data from data acquisition module 2; The data processing module 4 is used to process, analyze and store the data received from the data acquisition module 2; User interface module 5, used to provide an intuitive data display and operation control interface for the operator; The alarm and notification module 6 is used to trigger the alarm mechanism in time when an abnormal situation occurs in the base 8. The outer rotation of the adjustment box 9 is connected to the rotating rod 10, and the base 8 is installed on the outside of the rotating rod 10. The end of the rotating rod 10 inside the adjustment box 9 is installed with a worm gear 11. The outer rotation of the adjustment box 9 is connected to the worm 12, and the part of the worm 12 inside the adjustment box 9 is meshed with the worm gear 11; The indicator needle 13 is installed at one end of the rotating rod 10 that passes through the outside of the adjusting box 9. A scale line 14 is installed on the outside of the adjusting box 9, and the adjusting box 9 is at the center of the scale line 14. The internal thread of the adjusting box 9 is connected with a threaded ring 15. The limit rod 16 is installed on the part of the threaded ring 15 extending to the outside of the adjusting box 9, and the limit rod 16 is on the inner side of the threaded ring 15 and on the movement trajectory of the indicator needle 13.

[0021] In this embodiment, when the horizontal state of the base 8 needs to be leveled, the worm 12 can be directly rotated. Since the worm 12 is meshed with the worm wheel 11, the rotating rod 10 can be rotated through the worm wheel 11 while the worm 12 is rotated, thereby driving the base 8 to rotate around the rotating rod 10, so as to adjust the horizontal state. Before adjusting the horizontal state of the base 8, the threaded ring 15 can be rotated at this time, thereby driving the limit rod 16 to rotate until the limit rod 16 moves to the scale corresponding to the position where the base 8 needs to be on the scale line 14. When the rotating rod 10 is driven to rotate by the worm 12, the rotating rod 10 This drives the indicator needle 13 to rotate. When the indicator needle 13 hits the limit rod 16, the base 8 is adjusted to a horizontal state, which is convenient for quickly and accurately adjusting the base 8 to the target state. There is no need to adjust back and forth repeatedly to find the target state. After the base 8 is adjusted to a horizontal state, the threaded rod 18 can be rotated. The force generated by rotating the threaded rod 18 can drive the sliding block 19 to move along the sliding groove 17, thereby driving the limit plate 20 to move until the limit plate 20 hits the bottom of the base 8. Repeat the operation so that the two limit plates 20 respectively hit the base 8, provide additional support for the base 8, and improve the stability of the base 8 when in use.

The data storage unit stores real-time data, analysis results and historical records for subsequent viewing and analysis. The alarm triggering unit triggers the alarm mechanism when it detects that the levelness of the base exceeds a preset threshold or the levelness is abnormal. The processing process of the data processing unit is as follows: Data reception and verification: Receiving digital data from the data transmission module 3 and verifying the received data; Data preprocessing: The raw data is preprocessed by a digital filter, which is a finite impulse response FIR filter. The specific formula is as follows: ; in, is a sample of the input signal, is the coefficient of the filter, N is the order of the filter; Data Alignment and Integration: Integrate multiple data and calculate the current level of the base using the weighted average method. The formula for the weighted average method is as follows: ; Where x_i is the value of the i-th data point, w_i is the weight corresponding to x_i, and n is the total number of data points; Anomaly Detection: One or more thresholds are set to determine whether the levelness of the base 8 is within a normal range, and the calculated levelness is compared with the threshold.

[0023] In this embodiment, when the base 8 is adjusted to a horizontal state, the real-time data acquisition module 2 can receive the electrical signal from the sensor module 1 through the sensor module 1 and convert it into digital data. Once the data acquisition of the data acquisition module 2 is completed, the data transmission module 3 transmits the digital data to the data processing module 4 in real time. This transmission process can be carried out in a wired or wireless manner to ensure the real-time and reliability of the data. In the data acquisition module 2, the received data is displayed and stored in the storage device for subsequent analysis and reference. At the same time, the data processing module 4 processes and analyzes these data to identify the deformation trend, abnormality and horizontal state changes of the base; The user interface module 5 is the bridge for the interaction between the system and the operator. It receives the data from the data processing module 4 and displays it to the operator through the display. The operator can view the real-time data, analysis results and historical records through the input device, and perform necessary operations and controls. Finally, if the data processing module 4 detects that the deformation of the base exceeds the preset threshold or the levelness of the base exceeds the normal range, the alarm and notification module 6 will immediately trigger an alarm, which is achieved by flashing the alarm indicator, ringing the buzzer, and SMS notification services, so as to ensure that relevant personnel can quickly receive notifications and take corresponding measures.
