Description

Technical Field

[0001] The present invention relates to the technical field of parts production testing equipment, and in particular to a double-process center hole testing device and parts final inspection equipment. Background Art

[0002] In the field of machining, for parts that need to have a center hole machined at the end, the accuracy of the center hole is critical to the performance of the entire part. The center hole not only needs to be of the right size, but also needs to have a certain depth and shape to ensure the stability and durability of the part. In existing technologies, the detection of the center hole mainly focuses on the size and depth of the hole, especially when the center hole is a tapered hole, the size of which is usually determined by the size of the cone angle.

[0003] Although existing technologies are capable of basic inspection of center hole size and depth, there are some obvious limitations in actual operation. In particular, when it comes to the detection of the cone angle of a tapered center hole, existing methods usually rely on a standard-sized detection head. The main disadvantage of this method is that it can only effectively screen out center holes that are smaller than the standard size, while it cannot effectively detect center holes that are larger than the standard size and the depth of the center hole. This limits the comprehensiveness and accuracy of the inspection, and may cause unqualified parts to be mistakenly considered qualified, thereby affecting the quality and performance of the final product.

[0004] Therefore, it is necessary to develop a new detection device that can overcome the limitations of the existing technology and perform comprehensive and accurate detection of the cone angle size and depth of the center hole. Summary of the invention

[0032] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0034] The embodiment of the present application provides a dual-process center hole detection device, which is specially designed to solve the problem of limited functionality of standard-sized detection heads in traditional detection methods, particularly its inability to effectively detect the depth of the center hole and the limitations of center holes larger than the standard size.

[0035] The device comprises a working platform 10 , a bracket 20 , a limiting member 30 , a center hole detection component 40 and a detection supplement component 50 .

[0036] The bracket 20 is installed on the working platform 10 , and the limiting member 30 is arranged at the upper end of the bracket 20 and extends horizontally outwards for fixing and positioning the parts to be inspected.

[0037] In the embodiment of the present application, the bracket 20 includes an adjustable base 21 and an adjustable stand 22. The adjustable base 21 is movably mounted on the work platform 10 along a first direction, and the adjustable stand 22 includes a bottom plate 221 and a stand 222. The bottom plate 221 is movably mounted on the adjustable base 21 along a second direction, the first direction and the second direction are both located on a horizontal plane and are arranged perpendicular to each other, the stand 222 is vertically arranged at the upper end of the bottom plate 221, and the stopper 30 is arranged at the upper end of the stand 222.

[0038] This design allows the bracket 20 to be adjusted in two mutually perpendicular directions, thereby improving the adaptability of the device to components in different positions and directions, solving the problem of difficulty in adjusting traditional detection devices when facing components in different orientations, and enhancing the flexibility and accuracy of detection.

[0039] The center hole detection assembly 40 is vertically slidably installed at the lower end of the bracket 20, and includes a standard detection rod 48 and a sensor probe 47, wherein the upper end of the standard detection rod 48 is equipped with a standard conical joint 482 adapted to the standard center hole.

[0040] Specifically, the center hole detection assembly 40 includes the following components: an L plate 41 , an XY axis adjustable slide 42 , a contact 43 , a bushing 44 , a limit ring 45 , a probe fixing L plate 46 , a sensor probe 47 and a compression spring 49 .

[0041] The L plate 41 is slidably mounted on the vertical plate 222 and is formed with a first through hole 411. The XY axis adjustable slide 42 is mounted on the lower end of the L plate 41, so that the center hole detection assembly 40 can be accurately adjusted in the XY axis direction. The bushing 44 passes through the L plate 41 and the XY axis adjustable slide 42, and is fixed to the lower end of the XY axis adjustable slide 42, providing a stable support structure for the contact 43 and the standard detection rod 48.

[0042] The contact 43 is fixed to the upper end of the bushing 44, and is used to support and position the standard detection rod 48. The standard detection rod 48 includes a rod body 481 and a standard conical joint 482, wherein the standard conical joint 482 is connected to the upper end of the rod body 481, and the rod body 481 is movably arranged in the bushing 44, allowing precise depth adjustment during the detection process. A through hole that cooperates with the standard conical joint 482 is formed on the contact 43 to ensure that the standard conical joint 482 can be smoothly inserted and positioned. The limit ring 45 is connected to the outside of the rod body 481 and is arranged at the lower end of the bushing 44, and its outer diameter is larger than the inner diameter of the bushing 44 to limit excessive movement of the rod body 481 and ensure the safety and accuracy of the detection process.

[0043] The probe fixing L plate 46 is installed at the lower end of the XY axis adjustable slide 42 to provide a stable installation platform for the sensor probe 47. The sensor probe 47 is locked on the probe fixing L plate 46 and is coaxially arranged with the rod body 481 to ensure the accuracy and consistency of the measurement data. The compression spring 49 is arranged between the limit ring 45 and the probe fixing L plate 46 to play a buffering and stabilizing role, reducing the measurement error caused by external impact.

[0044] Preferably, the dual-process center hole detection assembly 40 is configured such that when the stop ring 45 contacts the bottom of the bushing 44, the standard conical connector 482 extends into the center hole of the component to be tested by a predetermined distance. This configuration allows the insertion depth of the standard conical connector 482 to be precisely controlled during the detection process, thereby adapting to center holes of different depths and ensuring the consistency and accuracy of the detection.

[0045] Specifically, the setting of the stop ring 45 provides a reliable stop point, and when it contacts the bottom of the bushing 44, it can ensure that the standard conical joint 482 will not be over-inserted into the center hole, thereby avoiding the risk of damage to the parts or mismeasurement. At the same time, this design also allows the extension length of the standard conical joint 482 to be adjusted according to the specific requirements of the parts to be tested, so as to meet the needs of detecting center holes of different depths.

[0046] The detection supplement component 50 includes a sleeve 51, a replacement detection cap 52 and a transport mechanism 53, and is used to detect the center hole of non-standard size. The sleeve 51 is open at both ends, and the replacement detection cap 52 is movably arranged inside the sleeve 51. Its lower end is adapted to the standard conical joint 482, and its upper end is a frustum with a larger cone angle. The transport mechanism 53 is used to transport the sleeve 51 to the upper end of the center hole detection component 40 to achieve supplementary detection of the center hole.

[0047] The sleeve 51 in the detection supplement component 50 is designed with a specific internal structure to enhance its functionality and stability. Specifically, a support ring 511 is formed at the inner lower end of the sleeve 51, and a support step 512 is further formed near the middle of the sleeve 51 on the support ring 511. The support step 512 is specifically used to support the replacement detection cap 52. The configuration of the support ring 511 and the support step 512 provides a stable support point for the replacement detection cap 52, ensuring that the replacement detection cap 52 can maintain the correct position and posture during the detection process.

[0048] The presence of the support ring 511 makes the sleeve 51 have a higher structural rigidity, reduces the deformation or displacement that may occur during the detection process, and thus ensures the accuracy of the detection. At the same time, the support step 512 provides a fixing and positioning platform for the complementary detection cap 52, so that the complementary detection cap 52 can be accurately aligned with the center hole to be detected, especially when detecting a center hole larger than the standard size, this design is particularly important.

[0049] The upper end of the contact 43 is formed with an annular groove 531 that matches the lower end surface of the sleeve 51. The transport mechanism 53 includes a rotating seat 54, a guide mounting plate 55, a lifting drive member 56, a horizontal connecting rod 57 and a clamping claw member 58. The rotating seat 54 is rotatably mounted on the working platform 10, the guide mounting plate 55 is vertically mounted on the upper end of the rotating seat 54, one end of the horizontal connecting rod 57 is vertically slidably mounted on the guide mounting plate 55, and the other end of the horizontal connecting rod 57 is connected to a clamping claw member 58, which is used to clamp the sleeve 51, and the lifting drive member 56 is used to drive the horizontal connecting rod 57 to rise and fall.

[0050] Preferably, one end of the horizontal connecting rod 57 away from the clamping claw member 58 is connected to a lifting drive plate 59, and a avoidance groove is formed on the guide mounting plate 55. The lifting drive plate 59 extends through the avoidance groove to the other side of the guide mounting plate 55, and the lifting drive member 59 is fixed to the rotating seat 54 and is drivingly connected to the lifting drive plate 59.

[0051] The lifting drive plate 59 passes through the avoidance groove to form a stable connection with the guide installation plate 55, thereby enhancing the overall structural stability of the conveying mechanism and ensuring the stability and accuracy during the conveying process.

[0052] The design of this transport mechanism allows the sleeve 51 to be moved to the detection position quickly and accurately, improving the detection efficiency, and through the rotation of the rotating seat 54, a rapid response to components in different positions is achieved, effectively solving the problem of difficulty in detecting large or special-shaped center holes in traditional detection methods.

[0053] Preferably, the rotating seat 54 is configured to have a first rotation state and a second rotation state, which further enhances the flexibility and adaptability of the device.

[0054] In the first rotation state, the combination Figure 1 As shown, the clamping claw 58 is completely staggered with the contact 43, avoiding interference or conflict with the contact 43 during the handling of the sleeve 51, thereby ensuring the smooth progress of the detection process. Figure 3 As shown, the clamping claw 58 is arranged corresponding to the contact 53, so that the transport mechanism can accurately place the sleeve 51 on the contact 43 for detection, thereby improving the accuracy and efficiency of the detection.

[0055] The dual-process center hole detection device of the present application effectively broadens the detection range through the above-mentioned design, and is particularly capable of detecting the depth of the center hole and the center hole larger than the standard size, thereby improving the quality and efficiency of parts processing.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
