Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a hardness testing device and system for aluminum alloy forgings. Background Technology

[0002] Aluminum alloy forgings are a processing method that uses forging machinery to apply pressure to aluminum alloy billets, causing them to undergo plastic deformation, thereby obtaining parts with specific mechanical properties, shapes, and dimensions. Forging can eliminate defects such as porosity in the casting state, optimize the microstructure of the metal, and retain complete metal flow lines. Therefore, the mechanical properties of forgings are generally superior to those of castings made of the same material.

[0003] The hardness of aluminum alloy forgings is a core indicator for measuring their mechanical properties. Traditionally, the hardness of aluminum alloy forgings is tested manually using a handheld Leeb hardness tester. This manual, single-point measurement method is not only inefficient but also fails to cover the complex curved surfaces of the forgings, resulting in significant measurement errors. Utility Model Content

The docking shaft and the central shaft are parallel to each other. The locking wheel has a fan-shaped structure and is concentrically fixedly connected to the central shaft. During the rotation drive, the central disk rotates. The docking shaft and the locking wheel alternately slide into the corresponding docking groove and locking groove. During the sliding of the docking shaft into the docking groove, the rotating disk can be driven to rotate by a preset angle. During the sliding of the locking wheel into the locking groove, the rotating disk can be locked.

[0010] Furthermore, the moving mechanism includes an X-axis moving component, a Y-axis moving component, and a Z-axis moving component. The X-axis moving component is connected to the rotating mechanism and is used to drive the rotating mechanism to perform reciprocating linear motion in the X-axis direction.

[0015] Compared with the prior art, the beneficial effects of this utility model include: During use, the clamping mechanism clamps the forging at a preset position and lifts the forging to a preset height. By controlling the moving mechanism, the moving mechanism can drive the rotating mechanism to perform reciprocating linear motion in the X, Y, and Z directions, thereby driving the detection mechanism to perform reciprocating linear motion in the X, Y, and Z directions. This allows the detection mechanism to reach the side of the forging, corresponding to a curved surface of the forging and maintaining a preset distance from it. Then, the transmitting end of the detection mechanism emits ultrasonic signals towards the forging, and the receiving end of the detection mechanism receives the feedback from the forging. The device uses the emitted echo signal to detect the hardness of one curved surface of the forging. After the hardness of one curved surface is detected, the rotating mechanism is controlled to drive the detection mechanism to rotate around the forging by a preset angle in a preset plane, so that the detection mechanism corresponds to another curved surface of the forging. After the hardness of the other curved surface is detected, the above operation is repeated to complete the hardness detection of all curved surfaces of the forging. This aluminum alloy forging hardness detection device can achieve full coverage detection of all curved surfaces of the forging, which not only improves the detection efficiency of forgings, but also improves the detection accuracy of forgings.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] This utility model provides a device for testing the hardness of aluminum alloy forgings, the structure of which is as follows: Figure 2 - Figure 5 As shown, the device includes a clamping mechanism, a detection mechanism 100, a rotating mechanism 200, and a moving mechanism 300. The clamping mechanism is used to clamp or release the forging at a preset position, and to lift the forging to a preset height or place the forging at a preset position. The detection mechanism 100 corresponds to the clamping mechanism, with its transmitting end used to emit ultrasonic signals to the forging and its receiving end used to receive the echo signals reflected by the forging. The rotating mechanism 200 is connected to the detection mechanism 100 and is used to drive the detection mechanism 100 to rotate intermittently around the forging in a preset plane at 360°. The moving mechanism 300 is connected to the rotating mechanism 200 and is used to drive the rotating mechanism 200 to perform reciprocating linear motion in the X, Y, and Z directions.

[0019] In use, the clamping mechanism clamps the forging at a preset position and lifts it to a preset height. By manipulating the moving mechanism 300, the moving mechanism 300 can drive the rotating mechanism 200 to reciprocate linearly in the X, Y, and Z directions, thereby driving the detection mechanism 100 to reciprocate linearly in the X, Y, and Z directions. This allows the detection mechanism 100 to reach the side of the forging, corresponding to a curved surface of the forging and maintaining a preset distance from it. Then, the transmitting end of the detection mechanism 100 emits an ultrasonic signal towards the forging, and the receiving end of the detection mechanism 100 receives the echo signal reflected by the forging, thus detecting the hardness of a curved surface of the forging. After the hardness detection of a curved surface of the forging is completed, by manipulating the rotating mechanism 200, the rotating mechanism 200 can drive the detection mechanism 100 to rotate within a preset plane. The forging is rotated by a preset angle so that the detection mechanism 100 corresponds to another curved surface of the forging. Simultaneously, the moving mechanism 300 drives the rotating mechanism 200 to reciprocate linearly in the X, Y, and Z directions, thereby driving the detection mechanism 100 to reciprocate linearly in the X, Y, and Z directions, maintaining a preset distance between the detection mechanism 100 and the forging. Then, the transmitting end of the detection mechanism 100 emits an ultrasonic signal towards the forging, and the receiving end of the detection mechanism 100 receives the echo signal reflected from the forging, thus detecting the hardness of the other curved surface of the forging. After the hardness detection of the other curved surface of the forging is completed, the above operation is repeated to complete the hardness detection of all curved surfaces of the forging. This aluminum alloy forging hardness detection device can achieve full coverage detection of all curved surfaces of the forging, improving both the detection efficiency and accuracy of the forging.

[0020] In a preferred embodiment, the clamping mechanism is a three-axis robotic arm clamping robot, the model of which is Zekeep. The clamping mechanism is not shown in the figure.

[0021] As a preferred embodiment, please refer to Figure 2 and Figure 4The detection mechanism 100 includes a base 110 and multiple probes 120. Each probe 120 is arranged in a rectangular array and connected to the base 110. The transmitting end of each probe 120 emits ultrasonic signals to the forging, and the receiving end of each probe 120 receives the echo signals reflected from the forging. The rotation mechanism 200 is connected to the base 110. During detection, driven by the rotation mechanism 200, the probes 120 rotate at 5° intervals to scan the curved surface of the forging. The transmitting end emits ultrasonic signals at a frequency of 5MHz, and the receiving end synchronously acquires the echo signals (sampling rate 100MHz). The single detection time is ≤3 seconds. In terms of speed, a single probe 120 is difficult to adapt to the irregular surface of the forging and is prone to forming a detection blind zone. Multiple probes 120 cooperate with the rotating mechanism 200 to achieve full coverage scanning of the forging surface through full matrix acquisition. For the basis of using ultrasound to detect the hardness of objects, please refer to the non-contact material hardness measurement method based on ultrasound disclosed in application number 201811360901.6.

[0022] As a preferred embodiment, please refer to Figure 2 and Figure 3 The rotating mechanism 200 includes a mounting plate 210, a bearing 220, a rotating plate 230, a rotating drive component 240, and a transmission assembly 250. The mounting plate 210, the bearing 220, and the rotating plate 230 are concentrically arranged. The outer ring of the bearing 220 is fixedly connected to the mounting plate 210, and the inner ring of the bearing 220 is fixedly connected to the rotating plate 230. The rotating drive component 240 is fixedly connected to the mounting plate 210. One end of the transmission assembly 250 is connected to the output shaft of the rotating drive component 240, and the other end of the transmission assembly 250 is connected to the rotating plate 230. An intermittent connection is used to convert the rotation of the output shaft of the rotation drive 240 into the intermittent rotation of the rotating disk 230. The rotating disk 230 is eccentrically connected to the detection mechanism 100, and the moving mechanism 300 is connected to the mounting disk 210. When the rotation drive 240 is activated, its output shaft rotates. The transmission assembly 250 converts the rotation of the output shaft of the rotation drive 240 into the intermittent rotation of the rotating disk 230, thereby driving the detection mechanism 100 to rotate around the forging at a preset angle in a preset plane, achieving full-coverage scanning of the forging surface.

[0023] In a preferred embodiment, the rotation drive 240 is a servo motor.

[0024] As a preferred embodiment, please refer to Figure 5The rotating disk 230 has multiple mating grooves 231 and multiple locking grooves 232.

Each locking groove 232 is also arranged in a ring array and located between adjacent mating grooves 231. The sidewalls of each locking groove 232 furthest from the center of the rotating disk 230 are open. The rotation drive member 240 is located on the side of the rotating disk 230. The output shaft of the rotation drive 240 is parallel to the central axis of the rotating disk 230. The transmission assembly 250 includes a central disk 251, a central shaft 252, a docking shaft 253, and a locking wheel 254. The central disk 251 is concentrically and fixedly connected to the output shaft of the rotation drive 240. One end of the central shaft 252 is concentrically and fixedly connected to the central disk 251. One end of the docking shaft 253 is eccentrically and fixedly connected to the central disk 251, and the docking shaft 253 is parallel to the central shaft 252. The locking wheel 254 has a fan-shaped structure. Concentrically fixed to the central shaft 252, during the rotation drive 240 driving the central disk 251 to rotate, the docking shaft 253 and the locking wheel 254 alternately slide into the corresponding docking groove 231 and locking groove 232. When the docking shaft 253 slides into the docking groove 231, it can drive the rotating disk 230 to rotate by a preset angle. When the locking wheel 254 slides into the locking groove 232, it can lock the rotating disk 230. When the rotation drive 240 is activated, its output shaft rotates. The movement causes the central disk 251 to rotate, which in turn causes the docking shaft 253 and the locking wheel 254 to rotate synchronously. This allows the docking shaft 253 and the locking wheel 254 to alternately slide into the corresponding docking groove 231 and locking groove 232. When the docking shaft 253 slides into the docking groove 231, it drives the rotating disk 230 to rotate by a preset angle. When the locking wheel 254 slides into the locking groove 232, it locks the rotating disk 230, thereby achieving intermittent rotation of the rotating disk 230 by a preset angle.

The Y-axis moving member 322 is also connected to the X-axis moving component 310. When the Y-axis moving member 322 is activated, it can reciprocate along the length direction of the Y-axis guide rail 321, thereby reciprocating along the Y-axis. In turn, it can drive the rotating mechanism 200 to perform reciprocating linear motion in the Y-axis via the X-axis moving component 310.

The calibration mechanism is electrically connected to each of the probes 120 and processes the data detected by each probe 120. It compares the data with a reference value to determine whether the forging hardness meets the standard. Before testing, the probes 120 scan a steel standard block (hardness HB150) to calculate the sound velocity reference value (v0=5900m / s). During calibration, a sound velocity-hardness mapping model is established using an aluminum alloy calibration piece (known hardness HB80-HB120). This model can be combined with temperature sensor data (accuracy ±0.5℃).

When the upstream end of the guide plate 510 is aligned with the side wall of the feed inlet 421 away from the third conveying assembly 430, the third conveying assembly 430 is connected to the first conveying assembly 410. When the detection mechanism 100 detects that the hardness of the forging meets the standard, the upstream end of the guide plate 510 is aligned with the side wall of the feed inlet 421 close to the third conveying assembly 430. At this time, the second conveying assembly 420 is connected to the first conveying assembly 410, and the qualified forging flows into the feed inlet 421. The forging is conveyed to the second conveying assembly 420 and then transported to the downstream processing step. When the detection mechanism 100 detects that the hardness of the forging is substandard, the driving assembly 520 drives the guide plate 510 to swing around its downstream end, so that the upstream end of the guide plate 510 aligns with the side wall of the feed inlet 421 away from the third conveying assembly 430. At this time, the third conveying assembly 430 is connected to the first conveying assembly 410, and the substandard forging flows into the third conveying assembly 430. Considering the third conveying assembly 430... When connected to the first conveying component 410, the forging on the first conveying component 410 will first reach the second conveying component 420 and then the third conveying component 430. After the forging reaches the second conveying component 420, due to the conveying effect of the second conveying component 420 on the forging, the forging cannot smoothly enter the third conveying component 430. At this time, the upstream end of the guide plate 510 can be rotated toward the third conveying component 430, and the guide plate 510 can push the forging into the third conveying component 430.

[0040] As a preferred embodiment, please refer to Figure 6The drive assembly 520 is disposed above the second conveying assembly 420 and the third conveying assembly 430. It includes a bracket 521, a rotating shaft 522, a connecting rod 523, and a telescopic drive member 524. The rotating shaft 522 is vertically arranged, with its upper end rotatably connected to the bracket 521 and its lower end connected to the downstream end of the guide plate 510. One end of the connecting rod 523 is connected to the upper end of the rotating shaft 522. The fixed end of the telescopic drive member 524 is hinged to the bracket 521. Then, the telescopic end of the telescopic drive member 524 is hinged to the other end of the connecting rod 523, which is used to drive the connecting rod 523 to swing back and forth. When the telescopic drive member 524 is activated, the telescopic end of the telescopic drive member 524 extends or shortens, which can drive the connecting rod 523 to swing back and forth, thereby driving the guide plate 510 to swing back and forth around the rotary shaft 522, realizing the connection between the second conveying component 420 and the first conveying component 410 or the connection between the third conveying component 430 and the first conveying component 410.

[0041] As a preferred embodiment, please refer to Figure 1 The aluminum alloy forging hardness testing system further includes a monitoring mechanism 600, which is electrically connected to the clamping mechanism. The monitoring mechanism 600 is used to monitor the position of the forging in the input channel to control the power supply of the clamping mechanism. When the forging reaches the preset position, the clamping mechanism is powered on, clamps the forging, and lifts the forging to the preset height. No manual intervention is required, and the system has a high degree of automation.

[0042] As a preferred embodiment, please refer to Figure 1 The monitoring mechanism 600 includes a photoelectric sensor switch 610, which is located on the upstream side of the clamping mechanism.

[0043] To better understand this utility model, the following is combined with... Figure 1 - Figure 6 The working principle of the technical solution of this utility model will be described in detail below: In use, the inlet end of the first conveying assembly 410 is connected to the outlet end of the upstream processing step, and the outlet end of the second conveying assembly 420 is connected to the inlet end of the downstream processing step. The forging completed in the upstream processing step enters the first conveying assembly 410. The photoelectric sensor switch 610 can monitor the position of the forging on the first conveying assembly 410. When the forging reaches the preset position, the clamping mechanism is energized, clamps the forging, and lifts it to the preset height. The X-axis moving member 312 is activated and can reciprocate along the length direction of the X-axis guide rail 311, thereby reciprocating along the X-axis, which in turn drives the rotating mechanism 200 to reciprocate in the X-axis. In linear motion, the Y-axis moving member 322 is activated, and it can reciprocate along the length direction of the Y-guide rail 321, thus reciprocating along the Y direction. This, in turn, drives the rotating mechanism 200 to perform reciprocating linear motion in the Y direction via the X-axis moving component 310. Similarly, the Z-axis moving member 332 is activated, and it can reciprocate along the length direction of the Z-guide rail 331, thus reciprocating along the Z direction. This, in turn, drives the rotating mechanism 200 to perform reciprocating linear motion in the Z direction via the Y-axis moving component 320 and the X-axis moving component 310, achieving three-axis motion of the rotating mechanism 200 in the X, Y, and Z directions. This, in turn, enables the detection mechanism 100 to perform reciprocating linear motion in the X, Y, and Z directions. The triaxial motion in the Y and Z directions allows the detection mechanism 100 to reach the side of the forging. The probe 120 corresponds to a curved surface of the forging and maintains a preset distance from it. Then, the transmitting end of each probe 120 emits ultrasonic signals towards the forging, and the receiving end of each probe 120 receives the echo signals reflected by the forging, thus detecting the hardness of a curved surface of the forging. After the hardness detection of a curved surface of the forging is completed, the rotation drive 240 is activated, and the output shaft of the rotation drive 240 rotates, driving the central disk 251 to rotate. This, in turn, drives the docking shaft 253 and the locking wheel 254 to rotate synchronously, allowing the docking shaft 253 and the locking wheel 254 to alternately slide and abut against their corresponding surfaces. Within the docking groove 231 and the locking groove 232, when the docking shaft 253 slides into the docking groove 231, it can drive the rotating disk 230 to rotate by a preset angle. When the locking wheel 254 slides into the locking groove 232, it can lock the rotating disk 230, thereby achieving intermittent rotation of the rotating disk 230 by a preset angle, so that the probe 120 corresponds to another curved surface of the forging. At the same time, the X-axis moving member 312 is activated again, and the X-axis moving member 312 can reciprocate along the length direction of the X-axis guide rail 311, thereby reciprocating along the X-axis, which can drive the rotating mechanism 200 to perform reciprocating linear motion in the X-axis. The Y-axis moving member 322 is activated again.The Y-axis moving member 322 can reciprocate along the length of the Y-axis guide rail 321, thus reciprocating along the Y-axis. This allows the rotating mechanism 200 to reciprocate linearly in the Y-axis via the X-axis moving component 310. The Z-axis moving member 332 is then activated, reciprocating along the length of the Z-axis guide rail 331. This allows the rotating mechanism 200 to reciprocate linearly in the Z-axis via the Y-axis moving component 320 and the X-axis moving component 310, achieving three-axis motion of the rotating mechanism 200 in the X, Y, and Z directions. This, in turn, enables the detection mechanism 100 to achieve three-axis motion in the X, Y, and Z directions. The axis movement maintains a preset distance between the detection mechanism 100 and the forging. Then, the transmitting end of each probe 120 emits ultrasonic signals towards the forging, and the receiving end of each probe 120 receives the echo signals reflected from the forging, thus detecting the hardness of another curved surface of the forging. After the hardness detection of the other curved surface is completed, the above operation is repeated to complete the hardness detection of all curved surfaces of the forging. This aluminum alloy forging hardness detection device can achieve full coverage detection of all curved surfaces of the forging, improving both the detection efficiency and accuracy. This aluminum alloy forging hardness detection system can meet the needs of assembly line production, eliminating the need for manual loading and unloading, and has a high degree of automation.

[0044] The aluminum alloy forging hardness testing device and system provided by this utility model have the following beneficial effects: (1) A single probe 120 is difficult to adapt to the irregular surface of the forging and is prone to forming a blind spot. Multiple probes 120 cooperate with the rotating mechanism 200 to achieve full coverage scanning of the forging surface through full matrix acquisition. (2) This aluminum alloy forging hardness testing device can achieve full coverage testing of all curved surfaces of the forging, which not only improves the testing efficiency of the forging, but also improves the testing accuracy of the forging. (3) This aluminum alloy forging hardness testing system can meet the needs of assembly line production, and does not require manual loading and unloading, with a high degree of automation.

[0045] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
