Description

Technical Field

[0001] This utility model relates to the field of threaded hole detection technology, specifically a threaded hole detection and measuring device. Background Technology

[0002] For example, the Chinese authorized patent, CN214039771U, entitled "(A Threaded Hole Inspection Gauge)," includes: a bracket, on which a servo motor and a lifting cylinder are fixed; a reducer is connected to the bottom of the servo motor; the coupling of the reducer passes through the bottom of the bracket and is fixedly connected to a floating mechanism; an outer sleeve is provided on the outside of the floating mechanism, and a cover is threadedly connected to the bottom of the outer sleeve; the floating mechanism includes a first conical clamp, a second conical clamp, a third conical clamp, and a fourth conical clamp; the fourth conical clamp has an axial hole that mates with a convex shaft; a lower support is fixedly provided at the bottom of the fourth conical clamp; and a threaded head is connected to the lower support. This utility model utilizes a floating mechanism to achieve horizontal floating of the threaded head, facilitating automatic alignment of the threaded head with the threaded hole and improving measurement efficiency and accuracy.

[0003] However, in the current machining industry, the main method for detecting the openness and depth of a large number of threaded holes is manual inspection. For companies with a large number of threaded holes in a single part, relying on manual inspection not only fails to achieve digitalization, but also easily misses some parts and cannot achieve 100% inspection. Furthermore, due to individual differences among personnel, the torque used to rotate the thread gauge during inspection cannot be standardized. Therefore, this method does not meet the existing needs. To address this, we propose a threaded hole inspection and measurement device. Utility Model Content

[0004] The purpose of this utility model is to provide a threaded hole detection and measurement device to solve the problem mentioned in the background art that in existing parts with a large number of threaded holes, relying on manual inspection not only fails to achieve digitization, but also easily misses some, making it impossible to achieve 100% detection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a threaded hole detection and measurement device, comprising: a bottom end of the device, a robotic arm disposed on the upper surface of the bottom end of the device, a motor and a connecting end mechanism disposed on one side of the robotic arm, the robotic arm including a first robotic arm, a second robotic arm, a third robotic arm, a fourth robotic arm, a fifth robotic arm and a sixth robotic arm, a connecting plate disposed at the lower end of the sixth robotic arm, a threaded power head disposed at one end of the connecting plate, a detection probe disposed at the lower end of the threaded power head, a threaded wall disposed on the outer wall of the detection probe, and a display mechanism disposed inside the outer wall of the threaded power head.

[0006] Preferably, the lower end of the first robotic arm is rotatably connected to the robotic hand, the upper end of the first robotic arm is mounted on one end of the second robotic arm, one end of the second robotic arm is mounted on one end of the third robotic arm, the other end of the third robotic arm is mounted on one end of the fourth robotic arm, the other end of the fourth robotic arm is mounted on one end of the fifth robotic arm, and the other end of the fifth robotic arm is mounted on the upper end of the sixth robotic arm.

[0007] Preferably, the other end of the connecting plate is provided with an internal mounting slot, and the sixth robotic arm is installed inside the internal mounting slot.

[0008] Preferably, a longitudinal rotating mechanism is provided between the motor and the connecting end mechanism. A mounting plate is provided at the upper end of the longitudinal rotating mechanism. Both ends of the longitudinal rotating mechanism are rotatably connected to the motor and the connecting end mechanism. The mounting plate rotates with the upper end face of the longitudinal rotating mechanism. A finished object is provided on the upper end face of the mounting plate. A plurality of threaded holes are provided inside the finished object.

[0009] Preferably, a threaded probe replacement frame is provided on one side of the upper surface of the bottom end of the device, and the threaded probe replacement frame is fixedly connected to the bottom end of the device.

[0010] Preferably, a power motor is provided on the upper end face of the threaded power head.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model can accurately determine the pass / fail and depth of a threaded hole by detecting the depth of the probe screwed into it, thus achieving digital threaded hole inspection. Simultaneously, the clutch inside the threaded power head is equipped with a fixed torque. When the probe reaches the torque due to a defective threaded hole, the clutch slides, preventing the thread gauge from getting stuck in the hole and damaging the part. This effectively avoids the current problem in the machining industry where the pass / fail and depth inspection of numerous threaded holes is mainly done manually. For companies with many threaded holes in a single part, relying on manual inspection not only fails to achieve digitalization but also easily leads to omissions and incomplete inspection. Furthermore, due to individual differences in personnel, the torque applied during thread gauge rotation cannot be standardized.

[0013] 2. The thread probe changing frame allows the equipment to automatically change the detection probe when inspecting different threaded holes, thus ensuring the smooth operation of the automation program. This ensures 100% complete inspection after programming and displays the inspection data and results of each threaded hole in the computer software for querying and traceability.

[0022] Example 1

[0023] Please see Figure 1-5An embodiment of this utility model provides a threaded hole detection and measurement device, comprising: a device bottom end 100, a robot arm 300 disposed on the upper end surface of the device bottom end 100, a motor 200 and a connecting end mechanism 201 disposed on one side of the robot arm 300, the robot arm 300 including a first robot arm 301, a second robot arm 302, a third robot arm 303, a fourth robot arm 304, a fifth robot arm 305 and a sixth robot arm 306, a connecting plate 307 disposed at the lower end of the sixth robot arm 306, a threaded power head 400 disposed at one end of the connecting plate 307, a detection probe 404 disposed at the lower end of the threaded power head 400, a threaded wall 403 disposed on the outer wall of the detection probe 404, and a display mechanism 402 disposed inside the outer wall of the threaded power head 400.

[0024] The depth to which the detection probe 404 is screwed into the threaded hole of the part can accurately determine the pass / fail status and depth of the threaded hole, realizing the digitalization of threaded hole inspection. At the same time, the clutch inside the thread power head 400 is set with a fixed torque. When the detection probe 404 rotates to the torque due to the threaded hole being unqualified, the clutch slides to prevent the thread gauge from getting stuck in the threaded hole and damaging the part.

[0025] Example 2

[0026] Please see Figure 1 and Figure 2 As a further implementation of this solution, the lower end of the first robotic arm 301 is rotatably connected to the robotic hand 300. The upper end of the first robotic arm 301 is mounted on one end of the second robotic arm 302. One end of the second robotic arm 302 is mounted on one end of the third robotic arm 303. The other end of the third robotic arm 303 is mounted on one end of the fourth robotic arm 304. The other end of the fourth robotic arm 304 is mounted on one end of the fifth robotic arm 305. The other end of the fifth robotic arm 305 is mounted on the upper end of the sixth robotic arm 306. A connection is provided between the motor 200 and the connecting end mechanism 201. The longitudinal rotation mechanism 202 has a mounting plate 203 at its upper end. Both ends of the longitudinal rotation mechanism 202 are rotatably connected to the motor 200 and the connecting end mechanism 201. The mounting plate 203 rotates with the upper end face of the longitudinal rotation mechanism 202. The upper end face of the mounting plate 203 has a finished object 20301. The finished object 20301 has several threaded holes inside. A threaded probe replacement frame 1001 is provided on one side of the upper end face of the equipment bottom 100, and the threaded probe replacement frame 1001 is fixedly connected to the equipment bottom 100.

[0027] The motor 200, connecting end mechanism 201 and longitudinal rotation mechanism 202 can effectively drive the holes on the finished product 20301 to perform all-round inspection.

[0028] Please see Figure 1 , Figure 3and Figure 4 As a further implementation of this solution, the other end of the connecting plate 307 is provided with an internal mounting slot 401, the sixth robotic arm 306 is installed inside the internal mounting slot 401, and the upper end face of the threaded power head 400 is provided with a power motor 4001.

[0029] The motor 4001 effectively provides power to the threaded power head 400.

[0030] Working principle: During use, the end of the detection probe 404 on the thread probe changer 1001 is changed according to the different specifications of the thread hole. Then, by screwing the detection probe 404 into the thread hole of the part, the opening and closing and depth of the thread hole can be accurately determined, realizing the digital detection of thread holes. At the same time, the clutch inside the thread power head 400 is set with a fixed torque. When the detection probe 404 reaches the torque due to the thread hole being unqualified, the clutch slides to prevent the thread gauge from getting stuck in the thread hole and damaging the part. The thread probe changer 1001 can automatically change the detection probe 404 when the equipment is detecting different thread holes. Therefore, the automation program can run smoothly and ensure 100% no omission detection after programming. At the same time, the detection data and results of each thread hole are displayed in the computer software for query and traceability.
