Description

Technical Field

[0001] This utility model relates to the field of CNC machining and inspection technology, specifically a CNC multifunctional irregular-shaped probe rod. Background Technology

[0002] With the rapid development of mobile terminal technology, the penetration rate of electronic devices such as smartphones, PDAs, and smartwatches has increased significantly, and their casings mostly adopt metal frame structures. Metal frames have become the mainstream choice for electronic device casings due to their wear resistance, heat dissipation, and ability to enhance the premium feel of the product. As electronic devices become increasingly thinner and lighter, and more precise, the processing precision requirements for metal frames are becoming increasingly stringent. Dimensional tolerances need to be controlled within extremely small ranges, while the requirements for external surface cleanliness are also constantly increasing. This makes accurate measurement of product dimensions during CNC machining increasingly important.

[0003] In the field of CNC machining, probe rods are key tools for ensuring product dimensional accuracy. They are mainly used to detect the related dimensions between clamping positions of machined parts, ensuring that the dimensions meet tolerance requirements. Early probe rods were mostly standardized straight rod structures. However, as the complexity of machined parts has increased, conventional straight rod probe rods have gradually revealed obvious defects. When inspecting complex irregular metal frames, interference between the probe rod and the machined part structure often results in some clamping dimensions being undetectable. Furthermore, the probe head and rod body are an integrated fixed structure, which cannot be adjusted according to the clamping depth and angle of different machined parts, resulting in poor adaptability. When facing diverse machining needs, the entire probe device needs to be replaced frequently, which not only increases machining costs but also reduces production efficiency. At the same time, this type of probe rod is not designed with a special structure for detection stability. In high-speed CNC machining environments, it is prone to detection jitter, leading to increased dimensional detection errors, which in turn causes product dimensional deviations and increased scrap rates, failing to meet the current high-precision machining and inspection requirements of metal frames for electronic devices.

[0018] 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.

[0019] Example

[0020] like Figure 1 and Figure 2 As shown, a CNC multifunctional irregular-shaped probe rod 6 includes a main rod body 1 and a connecting base 2. One end of the main rod body 1 is fixedly connected to a first bending part 11, and the other end of the main rod body 1 is fixedly connected to a second bending part 12. The other end of the second bending part 12 is fixedly connected to the connecting base 2. The side wall of the connecting base 2 has a through hole 21, and the end of the connecting base 2 is provided with a connecting rod 3. It adopts a segmented bending integrated design, which takes into account both structural rigidity and spatial adaptability, and can be adapted to CNC inspection scenarios with different depths and angles. The main rod body 1 serves as the core support component, bearing the connection force between the probe 6 and the connecting base 2. The double bending parts adjust the detection angle of the probe 6 and the installation position of the base respectively, avoiding interference with the workpiece or equipment during detection.

[0021] like Figure 1 As shown, the first bending part 11 is set at an angle of 150°-180° with the main rod 1, and the second bending part 12 is set at an angle of 120°-150° with the main rod 1. The first bending part 11 is set at an angle of 50°-180° with the main rod 1. The large angle design retains the straightness of the probe 6 detection and allows for a slight offset from the axis of the main rod 1, reducing the detection blind zone. This allows the probe 6 to detect deep cavities or narrow slits in a near-straight line state, while avoiding collision between the main rod 1 and the workpiece surface. The second bending part 12 is set at an angle of 20°-150° with the main rod 1. The medium angle design balances the ease of installation and the force transmission efficiency. It allows for flexible adjustment of the assembly angle between the connecting base 2 and the equipment, adapting to the detection module installation position of different CNC equipment, ensuring uniform force on the probe 6 rod as a whole, and improving detection accuracy.

[0022] Furthermore, in one embodiment of this utility model, an installation groove is provided at the end of the first bending portion 11. The installation groove connects to the main body rod and extends to the second bending portion 12. A probe 6 is detachably installed in the installation groove. The probe 6 is made of red tungsten steel. The through-type installation groove facilitates the positioning and calibration of the probe 6. The detachable design reduces the replacement cost after the probe 6 is worn out. It provides a stable installation channel for the probe 6 and ensures that the axis of the probe 6 is coaxial with the axis of the bending portion. The detachable structure enables quick replacement of the probe 6 without the need to replace the entire probe 6 rod.

[0023] like Figure 2 and Figure 4 As shown, a fixing base 5 is fixed at the connection between the first bent part 11 and the main rod 1; the fixing base 5 is provided with fixing holes 51; the reinforced fixing base 5 improves the connection strength between the bent part and the main rod 1, ensuring that the connection is fixed without loosening, and the fixing holes 51 are designed to facilitate external auxiliary positioning; the stress concentration of the bent part is dispersed during detection, avoiding deformation after long-term use; the fixing holes 51 can be used with bolts to partially fix the probe 6 rod, further improving the detection stability.

[0024] like Figure 3 As shown, the opening of the through hole 21 is recessed into the connecting base 2 to form an arc-shaped opening 22; the arc-shaped opening 22 reduces stress concentration, and the through hole 21 is designed to both reduce weight and allow for the installation of cables / air tubes; if the probe 6 needs to be connected to an external signal or air source, cables / air tubes can be installed through the through hole 21; the arc-shaped opening 22 prevents the edge of the opening from being worn by the cable due to vibration, while also reducing the overall weight of the connecting base 2.

[0025] like Figure 2 and Figure 4 As shown, the connecting rod 3 is provided with at least four external threads 4, which form a threaded area 41. One end of the connecting rod 3 near the connecting base 2 has an unthreaded area 4131. The ratio of the unthreaded area 4131 to the threaded area 41 is 1:4. The threads must be heat-resistant, with at least half of the threaded ring being threaded, and the circumference fully coated with 90-180 mm. Multiple external threads 4 ensure a secure connection, while the unthreaded area 4131 provides an adjustment margin for assembly. The 1:4 ratio balances assembly stability and adjustment flexibility. The external threads 4 enable the threaded connection between the connecting rod 3 and the CNC equipment, with at least four threads ensuring connection strength. The unthreaded area 4131 allows for fine-tuning of the probe 6 position during assembly, and the 1:4 ratio ensures a moderate adjustment range, preventing excessive adjustment that could lead to loosening of the connection.

[0026] Furthermore, in one embodiment of this utility model, the axis of the first bending portion 11 is collinear with the axis of the main rod 1, and the axis of the second bending portion 12 is collinear with the axis of the main rod 1; the collinear axis design improves the overall coaxiality of the probe 6 rod and reduces the angle error during detection; it ensures that the detection direction of the probe 6 is completely consistent with the designed trajectory, and improves the dimensional accuracy and positional accuracy of CNC detection.

[0027] like Figure 4 As shown, the fixed base 5 has an integrally formed positioning block 52 on its outer wall, and a positioning protrusion 53 is fixedly connected to the side of the positioning block 52 facing the connecting base 2. The fixed base 5 is made of yellow tungsten steel. The integrally formed positioning block 52 has a stable structure, and the positioning protrusion 53 enables quick assembly and positioning without additional calibration. During assembly, the positioning protrusion 53 can accurately match the positioning slot of the CNC equipment to quickly determine the installation position of the probe 6 rod and reduce assembly and calibration time.

[0028] Working principle: First, the connecting base 2 is threaded to the detection module of the CNC equipment through the external thread 4 of the connecting rod 3. The adjustment margin reserved in the unthreaded area 4131 allows for fine adjustment of the overall position of the probe 6 rod until the positioning protrusion 53 on the fixed base 5 precisely engages with the positioning groove of the equipment, completing the initial positioning. Then, the probe 6 rod is partially fixed by bolts through the fixing holes 51 of the fixed base 5 to prevent displacement due to vibration during detection. If the probe 6 needs to be connected to an external signal or air source, a cable / air pipe can be passed through the arc-shaped opening 22 through the through hole 21 on the side wall of the connecting base 2. The arc-shaped opening 22 protects the cable from wear. Second, the matching probe 6 is inserted into the mounting groove at the end of the first bend 11. Since the mounting groove runs through the main rod 1 to the second bend 12, it ensures that the axis of the probe 6 is collinear with the axis of the first bend 11 and the main rod 1 (in the embodiment), completing the precise positioning and fixing of the probe 6. If the probe 6 is worn, it can be directly removed and replaced from the mounting groove without disassembly. The entire probe consists of 6 rods. Finally, the CNC machine drives the probe 6 rods to move, with the main rod 1 serving as the core support to bear the detection force. The large angle of 50°-180° between the first bend 11 and the main rod 11 allows the probe 6 to penetrate deep into the workpiece's cavities and narrow gaps, while avoiding interference between the main rod 1 and the workpiece. The medium angle of 120°-150° between the second bend 12 ensures a reasonable assembly angle between the connecting base 2 and the equipment. The detection force of the probe 6 is smoothly transmitted to the connecting rod 3 through the main rod 1 and the second bend 12, with no significant stress loss. For higher precision detection, the fixed base 5 can be used for further reinforcement. The positioning block 52 and positioning protrusion 53 ensure that the probe 6's detection direction is completely consistent with the equipment's preset trajectory, ultimately achieving accurate detection of the size and position of irregularly shaped workpieces.

[0029] In summary, this CNC multi-functional irregular-shaped probe 6-bar, through the bending structure of the probe 6-bar and its detachable probe 6, effectively solves the problem of interference between conventional straight probe 6-bars and the workpiece. The bending angle can be flexibly designed according to the clamping position of the workpiece, ensuring that the probe 6 can accurately contact the clamping position to be tested, adapting to clamping position testing requirements of different depths and angles. It eliminates the need to replace the entire probe 6-bar device, significantly improving adaptability, reducing equipment replacement frequency, increasing CNC machining and testing efficiency, and reducing equipment procurement and maintenance costs.
