Description

Technical Field

[0001] This invention relates to the field of threaded workpiece inspection equipment, specifically to an intelligent go / no-go gauge inspection head applicable to multiple thread specifications and its control method. Background Technology

[0002] Multi-specification thread go / no-go gauge inspection heads are modular intelligent inspection units that can quickly change gauges or automatically adapt to multiple thread specifications, integrating torque control and data feedback. They are mostly used for full inspection of multi-specification cylinder block threads or chassis bolt holes, with dual judgment of torque and depth. They are suitable for intelligent go / no-go gauge inspection heads for multi-specification threads. However, existing intelligent go / no-go gauge inspection heads for multi-specification threads have some shortcomings, such as:

[0003] The automatic thread quick-change inspection system and its inspection method, with application number CN202111562064.7, can quickly disassemble and assemble the go and no-go gauge by adding a quick-change disc to the end of the go and no-go gauge and cooperating with the clamp. Compared with manual disassembly and assembly, it greatly improves work efficiency. However, in actual use, it is difficult to adjust the detection depth or detection state of the thread inspection equipment, which may lead to inaccurate detection when inspecting the threads of the workpiece.

[0004] Therefore, we propose an intelligent go / no-go gauge detection head and its control method applicable to multi-specification threads to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent go / no-go gauge inspection head suitable for multiple thread specifications, in order to solve the problem mentioned in the background art that current workpiece thread inspection equipment on the market is difficult to adjust the detection depth or detection state, which may lead to inaccurate detection when inspecting the threads of workpieces.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent go / no-go gauge inspection head suitable for multiple thread specifications, comprising a processing table and a feeding belt disposed on the top of the processing table, wherein a robotic arm clamp is disposed on the top of the processing table;

[0007] The processing table is equipped with a device platform on top, and the device platform is equipped with four sets of moving mechanisms on top, and the moving mechanisms are equipped with a detection mechanism on top. The detection mechanism is horizontally aligned with the right end of the feeding belt.

[0008] The testing mechanism includes a cylinder, and a first connecting shaft is provided at the rear end of the cylinder push shaft. A first universal ball is provided at the rear end of the first connecting shaft. A first telescopic sleeve is provided on the outside of the first universal ball. A second connecting shaft is provided at the rear end of the first telescopic sleeve. A limiting shaft is connected to the rear end of the second connecting shaft. A second telescopic sleeve is provided at the rear end of the limiting shaft. A second universal ball is provided between the limiting shaft and the second telescopic sleeve. A fixed shaft is provided at the rear end of the second telescopic sleeve. A tooth gauge testing head is connected to the rear end of the fixed shaft.

[0009] By setting a first universal ball and a second universal ball at the joint in the inspection mechanism, the problem of the workpiece getting stuck on the outside of the workpiece due to the thread protrusion can be avoided when the workpiece passes through the second connecting shaft and the fixed shaft. This makes it more convenient for the thread gauge inspection head to inspect the threads on the outside of the workpiece, and makes the equipment more accurate when inspecting the threads of the workpiece.

[0010] As a preferred technical solution of the present invention, a magnetic groove is provided on the outer side of the feeding belt, and the feeding belt limits the threaded workpiece through the magnetic groove. The top of the processing table is fixedly connected to the device table, and an electric push rod is provided on the top of the processing table. A mounting platform is provided on the top of the electric push rod, and the top of the mounting platform is fixedly connected to the moving mechanism.

[0011] The above technical solution enables the magnetic groove to limit the threaded workpiece by magnetic force, preventing the workpiece from shifting during feeding and ensuring that the workpiece is aligned with the detection mechanism. The electric push rod can adjust the height of the mounting platform to adapt to different specifications of threaded workpieces. The rigid fixation of the device platform provides stable support for the moving mechanism and the detection mechanism, avoiding errors caused by vibration during detection.

[0012] As a preferred embodiment of the present invention, the moving mechanism includes a mounting base, the bottom of which is fixedly connected to the mounting platform, and an electromagnetic slide rail is provided on the top of the mounting base. The driving end of the electromagnetic slide rail is driven by a stepper motor, and a slider is provided on the outer side of the electromagnetic slide rail.

[0013] The above technical solution enables the stepper motor to drive the electromagnetic slide rail, which in turn drives the slider to move precisely, thereby achieving horizontal position adjustment of the tooth gauge inspection head. The contactless transmission of the electromagnetic slide rail reduces mechanical wear and extends service life. The four sets of moving mechanisms work together to simultaneously inspect multiple sets of workpieces.

[0014] As a preferred embodiment of the present invention, the top of the slider is provided with a mounting bracket, and the top of the mounting bracket is fixedly connected to the cylinder in the detection mechanism. The top of the electromagnetic slide rail is provided with a sliding groove, and the bottom of the cylinder is slidably connected to the sliding groove.

[0015] The above technical solution enables the rigid connection of the mounting bracket, ensuring the cylinder is firmly fixed. The guiding effect of the slide groove on the cylinder ensures the smooth movement of the detection mechanism. The sliding connection design makes the cylinder respond quickly, adapting to the high-frequency detection requirements and increasing the accuracy of the equipment during movement.

[0016] As a preferred embodiment of the present invention, the cylinder is fixedly connected to the first connecting shaft, and the outer side of the first universal ball is slidably connected to the first telescopic sleeve, and the outer side of the second universal ball is slidably connected to the second telescopic sleeve. Both the first telescopic sleeve and the second telescopic sleeve are made of stretchable soft rubber.

[0017] The above technical solution enables the cylinder to drive the first connecting shaft to move axially, thereby causing the detection mechanism to extend and retract as a whole, realizing thread depth detection. The rotational characteristics of the first and second universal balls can adapt to different axes or angular deviations between the workpiece and the detection head, avoiding thread protrusion jamming. The elastic extension and retraction of the telescopic sleeve buffers the impact force during detection, protecting the thread gauge detection head and the workpiece, thus increasing the protective performance of the equipment.

[0018] As a preferred embodiment of the present invention, a positioning rod is provided on the outer side of the dental gauge inspection head, and a limiting ring is provided on the outer side of the positioning rod, and the limiting ring is located on the outer side of the dental gauge inspection head.

[0019] The above technical solution enables the positioning rod to provide radial positioning for the thread gauge inspection head, ensuring that it is coaxial with the workpiece during inspection. The limiting ring restricts the insertion depth of the thread gauge inspection head, avoiding excessive insertion that could damage the workpiece or the inspection head. The two work together to improve inspection repeatability and ensure consistent results across multiple batches of inspections.

[0020] As a preferred technical solution of the present invention, the thread gauge inspection head is equipped with a touch sensor, and the top of the processing table is equipped with a manual touch screen. The touch sensor inside the thread gauge inspection head is connected to the circuit signal of the manual touch screen. The manual touch screen can record the thread data of the workpiece, and the manual touch screen automatically records parameters such as the number of products inspected each day, the yield rate, and the fault problems.

[0021] The above technical solution enables the touch sensor to capture and detect contact signals in real time, transmit the data to the manual touch screen, visualize the detection data, automatically record the thread's qualified or unqualified status, generate a test report, and reduce manual recording errors.

[0022] As a preferred embodiment of the present invention, the manual touch screen is connected to the mechanical arm gripper circuit, and the manual touch screen can control the operation of the electric push rod and the cylinder.

[0023] The above technical solution enables integrated control of the manual touch screen, allowing for one-button start of the entire process of feeding, positioning, detection, and sorting. The operation is convenient, and parameters such as the height of the electric push rod, the thrust of the cylinder, and the detection depth can be adjusted through the touch screen. It is compatible with the detection of multiple specifications of threads and can be linked with the robotic arm fixture to automatically sort qualified and unqualified workpieces, reducing manual intervention.

[0024] A control method for an intelligent go / no-go gauge inspection head applicable to multiple thread specifications, comprising:

[0025] The thread depth of threaded workpieces is detected by moving the thread gauge inspection head using a manual touch screen.

[0026] The touch sensor inside the dental gauge head transmits the touch sensor data to the manual touch screen.

[0027] Compared with the prior art, the beneficial effects of the present invention are: by setting the first universal ball and the second universal ball at the joint in the detection mechanism, the problem of the workpiece getting stuck on the outside of the workpiece due to the thread protrusion can be avoided when the workpiece passes through the second connecting shaft and the fixed shaft and other structures. This makes it more convenient for the thread gauge detection head to detect the thread on the outside of the workpiece, and makes the device more accurate when detecting the thread of the workpiece.

[0028] Furthermore, by setting up electromagnetic slide rails and sliders, stepper motors can drive electromagnetic slide rails to move precisely, thereby adjusting the horizontal position of the tooth gauge inspection head. The contactless transmission of electromagnetic slide rails reduces mechanical wear and extends service life. The four sets of moving mechanisms work together to inspect multiple workpieces simultaneously.

[0029] Furthermore, by setting a first telescopic sleeve and a second telescopic sleeve on the first and second universal balls, the cylinder can drive the first connecting shaft to move axially, thereby causing the detection mechanism to extend and retract as a whole, realizing thread depth detection. The rotational characteristics of the first and second universal balls can adapt to different axes or angular deviations between the workpiece and the detection head, avoiding thread protrusions from getting stuck. The elastic extension and retraction of the telescopic sleeves buffers the impact force during detection, protecting the thread gauge detection head and the workpiece, thereby increasing the protective performance of the equipment.

Please refer to [link / reference]. Figures 1-10 The present invention provides a technical solution: an intelligent go / no-go gauge detection head suitable for multiple specifications of threads, including a processing table 1 and a feeding belt 2 set on the top of the processing table 1, wherein a robotic arm clamp 101 is provided on the top of the processing table 1;

The detection mechanism 6 is horizontally aligned with the right end of the feeding belt 2.

[0044] The testing mechanism 6 includes a cylinder 601, and a first connecting shaft 602 is provided at the rear end of the cylinder 601 push shaft.

A fixed shaft 609 is provided at the rear end of the second telescopic sleeve 608. A dental gauge testing head 612 is connected to the rear end of the fixed shaft 609.

[0045] The outer side of the feeding belt 2 is provided with a magnetic groove, and the feeding belt 2 limits the threaded workpiece through the magnetic groove. The top of the processing table 1 is fixedly connected to the device table 4, and the top of the processing table 1 is provided with an electric push rod 401, and the top of the electric push rod 401 is provided with a mounting table 402. The top of the mounting table 402 is fixedly connected to the moving mechanism 5.

[0046] The moving mechanism 5 includes a mounting base 501, the bottom of which is fixedly connected to the mounting platform 402, and an electromagnetic slide rail 503 is provided on the top of the mounting base 501. The driving end of the electromagnetic slide rail 503 is driven by a stepper motor 502, and a slider 504 is provided on the outer side of the electromagnetic slide rail 503.

[0047] The top of the slider 504 is provided with a mounting bracket 505, and the top of the mounting bracket 505 is fixedly connected to the cylinder 601 in the detection mechanism 6. The top of the electromagnetic slide rail 503 is provided with a slide groove 506, and the bottom of the cylinder 601 is slidably connected to the slide groove 506.

[0048] The cylinder 601 is fixedly connected to the first connecting shaft 602, and the outer side of the first universal ball 603 is slidably connected to the first telescopic sleeve 604, and the outer side of the second universal ball 607 is slidably connected to the second telescopic sleeve 608. The first telescopic sleeve 604 and the second telescopic sleeve 608 are both made of retractable soft rubber. The outer side of the dental gauge inspection head 612 is provided with a positioning rod 611, and the outer side of the positioning rod 611 is provided with a limiting ring 610, and the limiting ring 610 is located on the outer side of the dental gauge inspection head 612.

[0049] The thread gauge inspection head 612 is equipped with a touch sensor, and the top of the processing table 1 is equipped with a manual touch screen 3. The touch sensor inside the thread gauge inspection head 612 is connected to the circuit signal of the manual touch screen 3. The manual touch screen 3 can record the thread data of the workpiece, and automatically record parameters such as the number of products inspected each day, the yield rate, and the fault problems. The manual touch screen 3 is connected to the robotic arm clamp 101, and can control the operation of the electric push rod 401 and the cylinder 601.

[0050] A control method for an intelligent go / no-go gauge inspection head applicable to multiple thread specifications, comprising:

[0051] The thread depth of the threaded workpiece is detected by moving the thread gauge inspection head 612 according to the manual touch screen 3.

[0052] The touch sensor data is transmitted to the manual touch screen 3 based on the touch sensor inside the dental gauge head 612;

[0053] The manual touch screen 3 sets the feeding speed, and the feeding belt 2 magnetically attracts and limits the workpiece through the magnetic groove. When the workpiece reaches the inspection station, the cylinder 601 in the inspection mechanism 6 drives the thread gauge inspection head 612 to move, so as to fit with the thread on the outside of the workpiece.

[0054] During the screwing process of the thread gauge inspection head 612, the touch sensor collects the screwing depth and torque data in real time and transmits them to the manual touch screen 3. If the depth reaches the preset threshold and the torque does not exceed the upper limit, the gauge is judged to be qualified; if the screwing is blocked, that is, the torque is greater than the threshold, the gauge is judged to be unqualified. Then, the workpiece is clamped and classified by the robotic arm fixture 101.

[0055] Working principle: When using this intelligent go / no-go gauge inspection head applicable to multiple thread specifications, the threaded workpiece is first placed into the feeding belt 2. The magnetic groove on the outside of the feeding belt 2 uses magnetic force to attract and limit the workpiece, preventing the workpiece from shifting or rolling during the conveying process, and ensuring that the workpiece is smoothly conveyed to the inspection station along the preset trajectory. Then, the workpiece is moved to the designated position, and the external thread is inspected by the inspection mechanism 6. The cylinder 601 drives the first connecting shaft 602, the second connecting shaft 605 and the thread gauge inspection head 612 to move, so that the touch sensor inside the thread gauge inspection head 612 comes into contact with the thread on the outside of the workpiece, so that the touch sensor inside the thread gauge inspection head 612 transmits data back to the manual touch screen 3. The workpiece also passes through the thread gauge inspection head 612. When the thread on the surface of the workpiece is uneven, the first universal ball 603 or the second universal ball 607 will move, so that the first telescopic sleeve 604 or the second telescopic sleeve 608 will bend, thereby avoiding the inspection mechanism 6 from jamming when inspecting the thread of the workpiece.

[0056] After the thread gauge inspection head 612 contacts the workpiece thread, it performs a screw-in test according to the preset torque. The go gauge must be screwed into the full depth of the thread smoothly, and the no-go gauge must not be screwed in within the preset depth to complete the thread qualification judgment. During the inspection, the touch sensor inside the thread gauge inspection head 612 captures the screw-in depth signal in real time. When the detection depth reaches the preset threshold, the sensor sends a signal to the manual touch screen 3 to determine that the thread depth meets the standard. If the threshold is not reached or the screwing is blocked, it is judged as a defective product. Thus, the manual touch screen 3 controls the robotic arm clamp 101 to place the workpiece in the designated area for collection to complete the inspection work.

[0057] When adjusting the height of the inspection mechanism 6, the electric push rod 401 drives the mounting table 402 to rise and fall according to the workpiece height parameters, so that the inspection mechanism 6 is aligned with the workpiece conveying height of the feeding belt 2. The stepper motor 502 of the moving mechanism 5 drives the electromagnetic slide rail 503 to run, which drives the slider 504 and the cylinder 601 to move along the slide groove 506, adjusts the horizontal position of the tooth gauge inspection head 612, and adapts to the inspection requirements of workpieces with different spacing.

[0058] The threaded workpiece is placed into the feeding belt 2. The magnetic groove on the outside of the feeding belt 2 uses magnetic force to attract and limit the workpiece, preventing the workpiece from deviating or rolling during the conveying process, and ensuring that the workpiece is smoothly conveyed to the inspection station along the preset trajectory.

[0059] After a single inspection is completed, cylinder 601 drives the first connecting shaft 602 to retract in the opposite direction, the thread gauge inspection head 612 unscrews the workpiece thread, the first universal ball 603, the second universal ball 607 and the telescopic sleeve return to their initial state, and the moving mechanism 5 drives the inspection mechanism 6 back to its original position, waiting for the next inspection command.

[0060] The manual touch screen 3 automatically starts the equipment initialization, detects the operating status of core components such as the robotic arm clamp 101, the moving mechanism 5, and the detection mechanism 6, and inputs the specifications and qualification criteria of the threaded workpiece through the touch screen, such as the go gauge passing, the no-go gauge not passing, and the depth deviation ≤ ±1 turn, and presets the service life threshold of the thread gauge, such as 10,000 inspection times.

[0061] like Figure 8As shown, the thread gauge inspection head 612 and the workpiece thread hole are not coaxial with the thread gauge: When there is a misalignment between the workpiece thread hole and the thread gauge inspection head 612, the height of the thread gauge inspection head 612 can be adjusted by the electric push rod 401. At the same time, the workpiece will also fit against the outside of the thread gauge inspection head 612. The first universal ball 603 and the second universal ball 607 of the inspection mechanism 6 rotate under pressure. The two sets of universal balls can rotate along a plane perpendicular to the inspection direction. With the elastic deformation of the first telescopic sleeve 604 and the second telescopic sleeve 608, the misalignment is automatically compensated. At this time, under the thrust of the cylinder 601, the thread gauge inspection head 612 is smoothly screwed in along the actual axis of the workpiece thread hole, avoiding the thread protrusion from jamming with the thread gauge. The positioning rod 611 calibrates the radial position of the thread gauge inspection head in real time to ensure that the meshing depth with the workpiece thread is uniform during the screwing process. The touch sensor accurately captures the screwing stroke signal and transmits it to the manual touch screen 3 to determine whether the thread depth meets the standard, ensuring the accuracy of the inspection results under the misalignment state.

[0062] like Figure 9 As shown, the thread gauge inspection head 612 and the product hole of the workpiece thread have an angle: when there is an angle deviation between the workpiece thread hole and the thread gauge inspection head 612, the workpiece will fit against the inside of the thread gauge inspection head 612, thereby applying pressure to the first universal ball 603 or the second universal ball 607, so that the angle of the second universal ball 607 can be adaptively adjusted, the first universal ball 603 assists in fine adjustment, and the second universal ball 607 can rotate to adapt along the angle direction. The first telescopic sleeve 604 and the second telescopic sleeve 608 simultaneously undergo bending deformation in the corresponding direction, so that the axis of the thread gauge inspection head 612 is consistent with the tilt axis of the workpiece thread hole. The advance speed of the cylinder 601 is automatically adapted to a low-speed mode to reduce the thread engagement impact caused by the angle deviation and protect the workpiece thread from damage. The limit ring 610 limits the maximum tilt angle of the thread gauge inspection head to avoid excessive deformation that could damage the inspection mechanism 6. At the same time, the touch sensor monitors the screwing torque change in real time. If the torque is abnormal, it is determined that the thread is unqualified, ensuring the reliability of the inspection under the angle condition.

[0063] like Figure 10The thread gauge inspection head 612 shown is both off-axis and at an angle to the thread gauge of the workpiece thread hole. When the workpiece thread hole has both off-axis and angular deviations, the first universal ball 603 and the second universal ball 607 work together to achieve three-dimensional adaptive adjustment. The first universal ball 603 compensates for the off-axis deviation in the horizontal direction, and the second universal ball 607 cancels the tilt angle deviation. The first telescopic sleeve 604 and the second telescopic sleeve 608, through multi-directional elastic deformation, make the thread gauge inspection head 612 completely fit the actual posture of the workpiece thread hole. During inspection, the thread gauge inspection head is screwed in according to the preset torque. The touch sensor simultaneously collects depth and torque data. The manual touch screen 3 combines the dual deviation compensation parameters to make a pass / fail judgment. The go gauge must be screwed in smoothly to the preset depth, and the no-go gauge must not be screwed in within the depth threshold. Finally, accurate inspection under complex deviation conditions is achieved, eliminating misjudgment or jamming problems caused by dual deviations.

[0064] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0065] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
