This control system can logically process a program with control codes or other symbolic instructions, decode it, represent it with coded numbers, input it into the numerical control device through an information carrier, and after arithmetic processing, the numerical control device issues various control signals to control the actions of the machine tool, and automatically processes the parts according to the shape and size required by the drawing. Probe measurement is a commonly used measurement method, which is based on the detection of the electronic or voltage conduction performance of the surface of the object to be measured. By using a probe, a series of parameters and characteristic information related to the object to be measured can be obtained. The probe measurement principle can be divided into two categories: contact measurement and non-contact measurement.

[0003] During the production and processing of parts by a CNC numerical control machine tool, a measuring probe instrument is required to detect the distance between the tool and the part or other data of the part, such as voltage and current. Currently, the existing measuring probe instruments have advantages such as accurate detection.

[0004] However, the existing measuring probe instruments do not have a protective storage component, and cannot protect and store the measuring probe. As a result, the measuring probe is prone to damage during long-term use, which seriously affects the service life of the measuring probe and is not conducive to long-term use. Therefore, a measuring probe instrument in a CNC numerical control machine tool is proposed to solve the problems raised above. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: A measuring probe instrument in a CNC numerical control machine tool, including a housing, a box body and a connecting frame, and a protective storage component is arranged inside the box body;

[0007] The protective storage assembly includes a fixed rod fixedly connected inside the housing. The inner top wall of the housing is fixedly connected with a damping spring. The outer surface of the fixed rod is slidably connected with a moving sleeve. The inner side of the moving sleeve is fixedly connected with a measuring probe. The bottom end of the damping spring is fixedly connected with a pressing plate. The inner side of the box body is rotatably connected with a lead screw. The outer surface of the lead screw is threadedly connected with a moving plate. The inner side of the box body is fixedly connected with a limiting rod. The top end of the lead screw is fixedly connected with a knob.

[0008] Furthermore, threaded holes are formed on both the left and right sides of the box body and the connecting frame. Positioning screws are threadedly connected inside the threaded holes. A tool shank is fixedly connected to the top of the connecting frame.

[0009] Furthermore, a slot is formed on the top of the box body. A positioning plug rod is fixedly connected to the inner top wall of the connecting frame. The slot and the plug rod are inserted into each other.

[0010] Furthermore, the moving plate is slidably connected with the limiting rod. The top end of the lead screw penetrates through the box body.

[0011] Furthermore, the housing is cylindrical, and the box body is cuboid.

[0012] Furthermore, a round hole is formed on the bottom of the box body. The inner diameter of the round hole is larger than the outer diameter of the housing.

[0013] Furthermore, a movable hole is formed on the bottom of the housing. The inner diameter of the movable hole is larger than the outer diameter of the measuring probe.

[0014] Compared with the prior art, the present utility model provides a measuring probe instrument in a CNC machine tool, having the following beneficial effects:

[0015] In the measuring probe instrument in the CNC machine tool, by providing a protective storage assembly, when the measuring probe presses against a part for detection, the moving sleeve can slide upward on the outer surface of the fixed rod, so that the top of the measuring probe continuously presses against the bottom of the pressing plate, causing the damping spring to retract. Furthermore, through the elastic deformation of the damping spring, the pressure of the measuring probe can be absorbed and dispersed, thereby reducing vibration and protecting the measuring probe from damage. After the staff gets off work and the machine stops, by rotating the knob clockwise to rotate the lead screw, under the limiting action of the limiting rod, the moving plate can drive the housing to continuously move upward, and finally the housing and the measuring probe can be stored inside the box body together for protection, avoiding the situation of external force damage. Therefore, compared with the existing measuring probe instruments, the functions of protection and storage are realized, so that the measuring probe is not easily damaged during long-term use, thereby improving the service life of the measuring probe and being more conducive to long-term use.

[0025] The protective storage component includes a fixed rod 4 fixedly connected inside the housing 1. A damping spring 5 is fixedly connected to the inner top wall of the housing 1. A movable sleeve 6 is slidably connected to the outer surface of the fixed rod 4. A measuring probe 7 is fixedly connected to the inner side of the movable sleeve 6. The bottom end of the damping spring 5 is fixedly connected to a pressing plate 8. A lead screw 9 is rotatably connected to the inner side of the box body 2. A movable plate 10 is threadedly connected to the outer surface of the lead screw 9. A limiting rod 11 is fixedly connected to the inner side of the box body 2. The top end of the lead screw 9 is fixedly connected to a knob 12. When the measuring probe 7 presses against the part for detection, the movable sleeve 6 can slide upward on the outer surface of the fixed rod 4, so that the top of the measuring probe 7 continuously presses against the bottom of the pressing plate 8, causing the damping spring 5 to retract. Then, through the elastic deformation of the damping spring 5, the pressure of the measuring probe 7 is absorbed and dispersed, thereby reducing vibration and protecting the measuring probe 7 from damage.

[0026] And after the staff gets off work and shuts down the machine, by rotating the lead screw 9 clockwise with the knob 12, under the limiting action of the limiting rod 11, the movable plate 10 can drive the housing 1 to continuously move upward, and finally the housing 1 and the measuring probe 7 are both stored inside the box body 20 for protection to avoid external force damage. Thus, compared with the existing measuring probe instruments, the functions of protection and storage are realized, so that the measuring probe 7 is not easily damaged during long-term use, thereby improving the service life of the measuring probe and being more conducive to long-term use.

[0027] It should be noted that the housing 1 is cylindrical, the box body 2 is rectangular. A round hole 18 is opened at the bottom of the box body 2, and the inner diameter of the round hole 18 is larger than the outer diameter of the housing 1. An activity hole 19 is opened at the bottom of the housing 1, and the inner diameter of the activity hole 19 is larger than the outer diameter of the measuring probe 7.

[0028] Among them, the movable plate 10 is slidably connected to the limiting rod 11, and the top end of the lead screw 9 penetrates through the box body 2. By setting the limiting rod 11, the effect of limiting the movable plate 10 and improving its lifting stability is achieved.

[0029] Embodiment 2:

[0030] Please refer to Figure 1 、 Figure 3 and Figure 5 , on the basis of Embodiment 1, threaded holes 13 are opened on both the left and right sides of the box body 2 and the connecting frame 3. Positioning screws 14 are threadedly connected inside the threaded holes 13. A tool bar 15 is fixedly connected to the top of the connecting frame 3. By setting the threaded holes 13 and the positioning screws 14, the connecting frame 3 can be fixedly installed on the top of the box body 2, so that the staff can install this measuring probe instrument on the tool rest of the CNC machine tool through the tool bar 15 for use, which is more convenient.

[0031] Among them, a slot 16 is provided at the top of the box body 2, and a positioning plug rod 17 is fixedly connected to the inner top wall of the connecting frame 3. The slot 16 is inserted with the plug rod 17. By providing the slot 16 and the plug rod 17, the installation position of the connecting frame 3 can be positioned.

[0032] The working principle of the above embodiment is as follows:

[0033] When the measuring probe 7 abuts against the part for detection, the moving sleeve 6 can slide upward on the outer surface of the fixed rod 4, so that the top of the measuring probe 7 continuously abuts against the bottom of the abutting plate 8, causing the damping spring 5 to retract. Furthermore, through the elastic deformation of the damping spring 5, the pressure of the measuring probe 7 can be absorbed and dispersed, thereby reducing vibration and protecting the measuring probe 7 from damage. And after the staff gets off work and the machine stops, by rotating the knob 12 clockwise to rotate the lead screw 9, under the limiting action of the limiting rod 11, the moving plate 10 can drive the housing 1 to move upward continuously, so that the housing 1 and the measuring probe 7 are finally received into the interior of the box body 20 for protection to avoid external force damage.
