Description

Technical Field

[0001] This utility model relates to the field of automatic detection technology for machine tools, and in particular to an automatic probe mechanism for CNC machine tools. Background Technology

[0002] Currently, automatic probe mechanisms in CNC machine tools generally suffer from insufficient accuracy and protection: traditional probe mounting structures often adopt a vertical or inclined layout, resulting in poor probe base support rigidity, making them susceptible to machine tool vibration and cutting force interference, leading to fluctuations in measurement accuracy; the probe track protection design is weak, and cutting fluid penetration and metal shavings accumulation can easily cause guide rail jamming, wear of transmission components, and shorten service life. In addition, the probe replacement process is also relatively complicated, which brings certain adverse effects to the user experience. In order to overcome the shortcomings of existing technologies, we propose an automatic probe mechanism for CNC machine tools. Utility Model Content

[0003] The main purpose of this utility model is to provide an automatic probe mechanism for CNC machine tools, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An automatic probe mechanism for a CNC machine tool includes a machine tool slide. One end of the machine tool slide is detachably connected to an L-shaped fixing plate. The lower end of the L-shaped fixing plate is detachably connected to a marble base. The lower end of the marble base is detachably connected to a linear module. The linear module is equipped with circular double guide rails. A movable slide is arranged between the two circular double guide rails. The lower end of the movable slide is detachably connected to a probe holder. A probe is arranged on one side of the probe holder, and a headless screw for fixing the probe is arranged at the lower end of the probe holder. A servo motor is detachably connected to one side of the linear module, and the output end of the servo motor is connected to a coupling. A ball screw is installed inside the linear module, and a protective cover is detachably connected to the outside of the linear module.

[0006] Preferably, the L-shaped fixing plate is detachably connected to one end of the machine tool slide by bolts, the marble base is detachably connected to the lower end of the L-shaped fixing plate by bolts, and the linear module is detachably connected to the lower end of the marble base by bolts.

[0007] Preferably, the circular double guide rails are symmetrically distributed cylindrical guide rails, and the movable slide plate is constrained between the two circular double guide rails, restricting the movable slide plate to move only in a single direction.

[0008] Preferably, the probe holder is detachably connected to the lower end of the movable slide plate by bolts, and a probe interface is provided on one side of the probe holder, and the probe is locked and fixed in the interface by a headless screw.

[0009] Preferably, the servo motor is detachably connected to one side of the linear module by bolts, and the output end of the servo motor is detachably connected to the ball screw by a coupling.

[0010] Preferably, the protective cover is detachably connected to the outside of the linear module by bolts.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The automatic probe mechanism of this CNC machine tool uses an L-shaped fixing plate to convert the probe seat into a horizontal installation structure. Combined with the high rigidity and low thermal expansion characteristics of the marble base, it significantly enhances the stability of the circular double guide rails and ensures the micron-level repeatability of the probe positioning.

[0013] The automatic probe mechanism of this CNC machine tool effectively protects the probe's waterproofness and safety through its telescopic design, improving the probe's detection accuracy while ensuring higher usage accuracy and a longer service life.

[0014] The automatic probe mechanism of this CNC machine tool features a quick-change interface and a headless screw locking design for the probe holder, supporting rapid probe replacement. The high wear-resistant probe material and modular structure reduce wear and maintenance frequency, and maintain long-term high-precision measurement performance even under complex working conditions.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figure 1-4As shown, an automatic probe mechanism for a CNC machine tool includes a machine tool slide 1. One end of the machine tool slide 1 is detachably connected to an L-shaped fixing plate 2 by bolts. The L-shaped fixing plate 2 is made of high-strength lightweight alloy material. Its lower end is fixedly connected to a marble base 3 by bolts. The marble base 3 is ground to have excellent flatness and vibration resistance. The lower end of the marble base 3 is detachably connected to a linear module 4 by bolts. The linear module 4 has two circular double guide rails 5 symmetrically arranged inside. The movable slide plate 6 slides and engages with the two circular double guide rails 5 to ensure that the movable slide plate 6 moves precisely in a single direction.

[0022] The lower end of the movable slide plate 6 is detachably connected to the probe seat 7 by bolts. The probe seat 7 has a probe interface on one side. The probe 8 is locked and fixed in the interface by a headless screw 9. The linear module 4 is detachably connected to the servo motor 10. The output shaft of the servo motor 10 is connected to the ball screw 12 through the coupling 11. When the servo motor 10 is started, it drives the ball screw 12 to rotate, which drives the movable slide plate 6 to move precisely along the guide rail, so as to realize the contact measurement of the workpiece by the probe 8.

[0023] The external part of the linear module 4 is detachably connected to a protective cover 13 by bolts, which can effectively block the intrusion of external pollutants.

[0024] It should be noted that this utility model is an automatic probe mechanism for CNC machine tools. In use, the CNC system sends control commands to the servo motor 10 to drive the ball screw 12 to rotate, which in turn drives the moving slide plate 6 to make linear displacement along the circular double guide rail 5, so that the probe 8 can be accurately moved to the preset measurement position. When the probe 8 contacts the workpiece surface, it triggers a contact signal and feeds it back to the CNC system. The system combines the current coordinate data of the machine tool to calculate the size deviation or position error of the workpiece in real time, and automatically generates compensation commands to correct the machining parameters.

[0025] Meanwhile, the protective cover 13 can effectively prevent contaminants such as cutting fluid and debris from entering the interior of the linear module 4, ensuring the cleanliness and durability of the transmission components. The probe holder 7 adopts a quick-change structure design, and probes 8 of different geometries can be quickly replaced by adjusting the headless screw 9 to adapt to the diverse measurement needs of complex workpieces.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
