[0002] In the field of machining detection technology, CNC machining detection probe is a commonly used detection tool. The CNC machining detection probe is installed in the detection machine and used. It touches the contour of the workpiece under the drive of the detection machine. According to the displacement signal fed back to the detection machine by the CNC machining detection probe, the detection machine calculates the contour parameters of the workpiece and compares it with the theoretical reference value pre-recorded in the detection machine to obtain the deviation value between the actual value and the theoretical value. According to the deviation value, qualified products and defective products can be distinguished, and the deviation value can be used to correct the contour of the workpiece to save defective products. In the prior art, the detection part of the CNC machining detection probe is generally cylindrical. When the inner side wall of the detection hole is provided with a protruding structure or has burrs, it is difficult for the cylindrical detection part to adhere to the surface of the workpiece, and the actual length of the detection part cannot be adjusted according to the actual length of the detection hole, which leads to inconvenience in detection and a large error between the contour parameter value calculated by the detection machine and the actual value.

[0003] Therefore, there is an urgent need for a probe that can solve the problems that the probe piece cannot smoothly abut against the surface of the workpiece to be measured and the length of the probe piece cannot be adjusted, thereby improving the convenience of use and the accuracy of the measurement results.

It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0034] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components.

[0035] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0036] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0037] This embodiment provides a probe, such as Figure 1-Figure 3 As shown, the probe includes a base 10, a mounting seat 20, an avoidance member 30 and a probe 40; wherein the base 10 is connected to the detection device; the mounting seat 20 is arranged at an end of the base 10 away from the detection device; the mounting seat 20 is provided with a mounting hole 21 along its axial direction, one end of the avoidance member 30 is arranged in the mounting hole 21, the avoidance member 30 can be extended and retracted along the axial direction of the mounting seat 20, and the diameter of the avoidance member 30 is smaller than the diameter of the mounting seat 20; the probe 40 is arranged at an end of the avoidance member 30 located outside the mounting hole 21, the diameter of the probe 40 is larger than the diameter of the avoidance member 30, and the side of the probe 40 away from the avoidance member 30 can abut against the surface of the workpiece.

[0038] In the above structure, the base 10 is connected to the detection device to ensure stability during the detection process. The diameter of the avoidance member 30 is smaller than the diameter of the mounting seat 20, which can provide effective avoidance space for the detection process, thereby avoiding the avoidance member 30 from colliding with the detection groove. At the same time, since the avoidance member 30 can be extended and retracted along the axial direction of the mounting seat 20, the length of the avoidance member 30 extending out of the mounting seat 20 can be adjusted according to the actual depth of the detection groove, thereby ensuring the convenience of the detection process; in addition, the probe 40 is arranged at the other end of the avoidance member 30, and its diameter is greater than the diameter of the avoidance member 30. On the one hand, it can avoid the avoidance member 30 from having too small a diameter and resulting in insufficient strength when abutting against the workpiece, thereby causing reduced detection accuracy; on the other hand, the outer periphery of the probe 40 can abut against the burrs or protruding structures on the inner wall of the detection groove, thereby ensuring that the side of the probe 40 away from the avoidance member 30 can smoothly abut against the surface of the workpiece, thereby ensuring the accuracy of the detection result, and then the workpiece can be trimmed in the next step according to the detection to ensure the yield rate of the workpiece.

[0039] To simplify the manufacturing process, the mounting hole 21 is a threaded hole, and the outer periphery of the avoidance member 30 is provided with threads. The avoidance member 30 can be threadedly connected to the mounting hole 21, so that it can be extended and retracted along the axial direction of the mounting seat 20. This arrangement can achieve the axial extension and retraction of the avoidance member 30 along the mounting seat 20 by simply screwing the avoidance member 30, which is simple and convenient to operate, can improve operating efficiency, and also facilitates subsequent maintenance and replacement of the avoidance member 30.

[0040] In addition, if Figure 3 As shown, the probe further includes an adjusting member 50, which is threadedly connected to the mounting hole 21 and can move axially along the mounting base 20. The bottom end of the adjusting member 50 can abut against the end of the avoidance member 30 away from the probe 40. By providing the adjusting member 50 and abutting against the top end of the avoidance member 30, the end of the avoidance member 30 not provided with the probe 40 can be prevented from extending from the top end of the mounting base 20. That is, when shortening the extension length of the avoidance member 30, it is necessary to first screw the adjusting member 50 to make it rise axially along the mounting base 20, and then screw the avoidance member 30 to make the end not provided with the probe 40 abut against the bottom end of the adjusting member 50 again; when increasing the extension length of the avoidance member 30, first screw the avoidance member 30 to extend it to the desired length, and then screw the adjusting member 50 to make its bottom end abut against the top end of the avoidance member 30.

[0041] In addition, to make the screwing process more convenient, Figure 3 As shown, the top of the adjusting member 50 is provided with an adjusting slot 51. A screwing workpiece (such as a flat screwdriver) can be inserted into the adjusting slot 51 and screwed. The structure is simple and the operation is simple and convenient, thereby improving the operating efficiency.

[0042] In addition, if Figure 1 and Figure 3As shown, the mounting base 20 includes a first body 22 and a second body 23 connected to each other along the axial direction. The first body 22 is coaxial and detachably connected to the base 10, and the diameter of the second body 23 gradually decreases as it moves away from the first body 22. This configuration enables the second body 23 to be truncated into a cone shape, thereby ensuring that the diameter of the mounting base 20 gradually decreases as it moves away from the base 10. This allows the mounting base 20 to better avoid structures at the detection location during detection, thereby improving the user experience.

[0043] In addition, if Figure 3 and Figure 4 As shown, one end of the first body 22 away from the second body 23 is provided with a connector 221 and a locking member 222, and the end of the base 10 close to the mounting base 20 is provided with a connecting hole. When the connector 221 is threadedly connected to the connecting hole of the base 10, the locking member 222 can abut against the base 10. First, the arrangement of the connector 221 and the connecting hole can simplify the connection relationship between the mounting base 20 and the base 10. At the same time, the arrangement of the threaded connection only requires screwing the mounting base 20 to complete the disassembly and assembly. In addition, since the first body 22 is also provided with the locking member 222, when the first body 22 is connected to the connecting hole through the connector 221, the locking member 222 is clamped between the first body 22 and the base 10, which can prevent the first body 22 from shaking, thereby ensuring the stability of the probe 40 during the detection process, thereby generating accurate detection results. It should be noted that the locking member 222 can be a structure with a certain elasticity such as a rubber gasket, which can effectively prevent the base 10 from being scratched, thereby improving the service life.

[0044] It is further explained that if Figure 1 and Figure 3 As shown, the mounting base 20 is provided with a first through hole 24 in the radial direction, and the rotating member can extend into the first through hole 24 and drive the mounting base 20 to rotate. In this arrangement, the rotating member can be any rod-shaped structure. After extending it into the first through hole 24, the operator can screw the rotating member to make the rotating member drive the mounting base 20 to rotate, which can effectively reduce the rotational torque and thus improve the operating efficiency. In addition, in order to further improve the efficiency of assembly and disassembly, the first body 22 and the second body 23 are integrally formed. When the rotating member passes through the first through hole 24 and rotates, the first body 22 and the second body 23 can rotate synchronously, and there is no need to install the first body 22 before installing the second body 23, which improves the speed of installation and disassembly. At the same time, the one-piece structure can also reduce the difficulty and cost of processing.

[0045] like Figure 1 and Figure 3As shown, a joint 12 is provided at one end of the base 10 away from the mounting seat 20, and the joint 12 can be detachably connected to the detection device. A thread is provided on the outer periphery of the joint 12, which enables the base 10 to be threadedly connected to the detection device, which is convenient for disassembly and also convenient for subsequent maintenance and replacement. Correspondingly, a second through hole 11 is provided in the radial direction of the base 10, and the rotating member can extend into the second through hole 11 and drive the base 10 to rotate. When the base 10 needs to be installed or disassembled, it is only necessary to insert the rotating member (any rod-shaped structure) into the second through hole 11 and rotate the rotating member. It is not only easy to operate, but also has a small rotational torque, and the installation or disassembly process is more labor-saving, thereby improving the user experience.

[0046] In summary, the use of the probe in this embodiment can not only successfully solve the problem that the detection member cannot smoothly abut against the surface of the workpiece to be measured, but also quickly adjust the extension length of the probe 40, thereby improving the convenience of detection and the accuracy of the detection results.

[0047] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
