Technical Field

[0001] The present invention relates to the technical field of roughness detection, and more specifically, the present invention relates to a detection device for precious metal ornaments with overall detection. Background Art

[0002] The detection device for overall detection of the surface roughness of precious metal ornaments has the function of quality control, ensuring quality standards. Surface roughness is a key indicator to measure the fineness of precious metal ornaments during processing, reducing the defective rate. In the production process, through rapid and comprehensive detection, ornaments with unqualified surface roughness can be promptly detected, enabling producers to rework and correct them as early as possible, reducing the output of defective products, and saving production costs.

[0003] In the existing published literature, the patent with the patent announcement number CN116625190A discloses a surface roughness detection device for metal castings. In this technology, straight tooth segments meshing with the annular teeth are respectively provided on the inner walls of both sides of the moving rack frame; a long strip slide rod fixedly connected to the fixed plate body, and a sliding plate is inserted on the long strip slide rod. By pushing the detection device to align the center position, this invention reduces the risk of damage caused by manually installing high-sensitivity sensors. The moving component pauses the workpiece being detected while pushing, reducing the error in measurement.

[0004] However, this technology still has the following problems. After processing large-piece placed precious metal ornaments, in order to ensure the quality of large-piece placed precious metal ornaments is qualified, it is necessary to detect the surface roughness of their surfaces. Large-piece placed precious metal ornaments have different surfaces, and at the same time, the shapes of each surface are irregular. This requires first detecting the roughness of an irregular surface, then detecting the roughness of other irregular surfaces, and finally detecting the outer surface of the top of the large-piece placed precious metal ornaments. It is difficult to synchronously detect the different regular surfaces of large-piece placed precious metal ornaments and synchronously detect the surface roughness of the outer surface of the top of large-piece placed precious metal ornaments, resulting in a significant decline in detection efficiency. Therefore, a detection device for precious metal ornaments with overall detection is needed. Summary of the Invention

The controller is electrically connected to the lifting electric cylinder and the first roughness measuring probe, the controller is electrically connected to the displacement motor, the lateral displacement distance sensor and the vertical displacement distance sensor, and the controller is electrically connected to the rotation motor, the angle sensor and the second roughness measuring probe.

[0008] When the present technology is in use, the lifting electric cylinder pushes the linkage disk to move upward, the linkage disk drives multiple hinge shafts to move upward, multiple hinge shafts respectively drive the bottoms of multiple sleeve rods to move upward synchronously, and the push shaft drives the concave block to move upward obliquely. The sliding frame causes the socket slider to move upward obliquely, and the socket slider moves upward obliquely along the outer wall of the inclined column.

[0011] When in use, while the sliding frame tilts and moves upward, multiple displacement motors respectively drive multiple displacement screws to rotate forward. The support block supports the displacement motors. The displacement screws drive the threaded sleeve blocks to move rightward under the action of the threaded driving force. The threaded sleeve blocks drive the connecting blocks to move rightward, and the sleeves drive the first roughness measurement probes to move rightward. At the same time, the two lateral displacement distance sensors move rightward. The right lateral displacement distance sensor senses the distance of the inner wall on the right side of the limit frame. When the distance sensed by the right lateral displacement distance sensor is the same as the displacement distance set by the controller, the displacement motor is started by the controller to drive the displacement screw to rotate in reverse. At the same time, the threaded sleeve block drives the connecting block to move leftward, and the sleeve drives the first roughness measurement probe to move leftward. The first roughness measurement probe performs a lateral displacement movement detection on the irregular inclined surface of the outer wall of the precious metal seat. At the same time, the left lateral displacement distance sensor senses the distance of the inner wall on the left side of the limit frame. When the distance value sensed by the left lateral displacement distance sensor is the same as the distance set by the controller, the displacement screw is continuously driven to rotate forward by the displacement motor.

[0012] Preferably, the top synchronous roughness detection assembly includes a fixed block fixedly arranged on the upper surface of the linkage disk; a rotary motor is fixedly installed on one side of the fixed block. The output end of the rotary motor is fixedly connected with a rotating shaft. An angle sensor is installed at the bottom end of the rotating shaft. The sensing end of the angle sensor is fixedly connected with the rotating shaft. The angle sensor is fixedly connected with the linkage disk; a socket rotating block is fixedly installed on the outer wall of the rotating shaft. A connecting strip is fixedly installed on one side of the socket rotating block. The bottom end of the connecting strip is fixedly connected with a turntable. The turntable is rotatably connected with the linkage disk; a plurality of linkage rods are fixedly connected to the upper surface of the turntable and near its edge line.

The plurality of linkage rods are arranged in an equidistant circular arrangement. The cross-sectional shape of the linkage rod is circular. The plurality of second roughness measurement probes are arranged in an equidistant circular arrangement, and the second roughness measurement probes are fixedly connected with the linkage strips.

[0013] When this technology is in use, while the sliding frame tilts and moves upward, the linkage disk drives the fixed block to move upward, the rotating motor drives the rotating shaft to move upward, and the connecting bar drives the turntable to move upward. The linkage rod drives the linkage bar to move upward, and multiple second roughness measurement probes synchronously move upward and detect on the outer wall of the precious metal main ornament. At the same time, the rotating motor drives the rotating shaft to rotate counterclockwise by 110 degrees. The sleeved rotating block drives the connecting bar to rotate counterclockwise by 110 degrees. The turntable rotates counterclockwise by 110 degrees on the linkage disk. The linkage rod drives the linkage bar to rotate counterclockwise by 110 degrees. When the angle sensed by the angle sensor is -110 degrees, the controller then starts the rotating motor to drive the rotating shaft to rotate clockwise by 110 degrees.

The turntable drives multiple linkage rods to rotate clockwise by 110 degrees. The linkage rod drives the linkage bar to rotate clockwise by 110 degrees. In this way, multiple second roughness measurement probes can perform reciprocating horizontal movements while moving upward, and can simultaneously detect the roughness at different points on the outer wall of the precious metal main ornament.

[0014] The technical effects and advantages of the present invention are as follows:

[0015] 1. Through the synchronous vertical roughness detection component of the present invention, the upward moving cylinder pushes the linkage disk upward. Multiple articulated shafts respectively drive the bottoms of multiple sleeve rods to move upward synchronously. The concave block drives the sliding frame to tilt and move upward. The sliding frame drives the displacement screw rod to tilt and move upward. The sliding frame tilts and moves upward along the gap between the limit frame and the inclined frame. The threaded sleeve block causes the sleeve to tilt and move upward. Multiple first roughness measurement probes perform distance sensing on multiple irregular inclined surfaces on the outer surface of the precious metal seat, and synchronously detect the vertical roughness of multiple irregular inclined surfaces on the outer wall of the precious metal seat, greatly improving the efficiency of detecting the overall roughness of the precious metal seat.

[0016] 2. The present invention adopts a synchronous horizontal displacement roughness detection component. While the sliding frame tilts and moves upward, multiple displacement motors respectively drive multiple displacement screw rods to rotate forward. The threaded sleeve block moves rightward along the inner wall of the sliding frame. The sleeve drives the first roughness measurement probe to move rightward. When the distance sensed by the horizontal displacement distance sensor on the right side is the same as the displacement distance set by the controller, the controller starts the displacement motor to drive the displacement screw rod to rotate in reverse. The sleeve drives the first roughness measurement probe to move leftward. Multiple first roughness measurement probes can perform horizontal displacement roughness detection on multiple irregular inclined surfaces on the outer wall of the precious metal seat, greatly improving the efficiency of roughness detection.

[0017] 3. The present invention utilizes the top synchronous roughness detection component. When the sliding frame tilts and moves upward, the linkage disk drives the fixed block to move upward, and the connecting bar drives the turntable to move upward. In this way, the turntable can drive multiple linkage rods to move upward synchronously, and the linkage bar causes the second roughness measurement probe to move upward. Multiple second roughness measurement probes perform synchronous upward movement detection on the outer wall of the precious metal main ornament. The rotating motor drives the rotating shaft to rotate counterclockwise by 110 degrees, the rotating shaft drives the socket rotating block to rotate counterclockwise by 110 degrees, and the linkage bar causes the second roughness measurement probe to rotate counterclockwise by 110 degrees. When the angle sensed by the angle sensor is -110 degrees, the controller then starts the rotating motor to drive the rotating shaft to rotate clockwise by 110 degrees. The socket rotating block drives the connecting bar to rotate clockwise by 110 degrees, and the turntable drives multiple linkage rods to rotate clockwise by 110 degrees. Multiple second roughness measurement probes can perform reciprocating lateral movement while moving upward, and can synchronously perform roughness detection on multiple points on the outer wall of the precious metal main ornament at the top of the precious metal seat, greatly improving the efficiency of roughness detection.

[0018] According to the mutual influence of the above multiple functions, first, multiple first roughness measurement probes perform distance sensing on multiple irregular inclined surfaces on the outer surface of the precious metal seat. Second, multiple first roughness measurement probes can perform lateral displacement roughness detection on multiple irregular inclined surfaces on the outer wall of the precious metal seat. Finally, multiple second roughness measurement probes can synchronously perform roughness detection on multiple points on the outer wall of the precious metal main ornament at the top of the precious metal seat. In summary, it is possible to perform synchronous detection on different regular surfaces of the large precious metal seat, and synchronously perform roughness detection on the outer surface of the precious metal main ornament at the top of the large precious metal seat, greatly improving the detection efficiency.

[0038] In this embodiment, as shown in the attached Figure 9 - attached Figure 11As shown in the figure, the top synchronous roughness detection component includes a fixed block 28 fixedly arranged on the upper surface of the linkage disk 3; a rotary motor 29 is fixedly installed on one side of the fixed block 28, and the output end of the rotary motor 29 is fixedly connected to a rotating shaft 30. An angle sensor 31 is installed at the bottom end of the rotating shaft 30. The sensing end of the angle sensor 31 is fixedly connected to the rotating shaft 30, and the angle sensor 31 is fixedly connected to the linkage disk 3; a socket rotating block 32 is fixedly installed on the outer wall of the rotating shaft 30, and a connecting bar 33 is fixedly installed on one side of the socket rotating block 32. The bottom end of the connecting bar 33 is fixedly connected to a turntable 34, and the turntable 34 is rotatably connected to the linkage disk 3.

[0039] A plurality of linkage rods 35 are fixedly connected to the upper surface of the turntable 34 and near its edge line. The top end of each linkage rod 35 is fixedly connected to a linkage bar 36, and a second roughness measurement probe 37 is installed on one side of the linkage bar 36. The plurality of linkage rods 35 are arranged in an equidistant circular ring distribution. The cross-sectional shape of the linkage rod 35 is circular. The plurality of second roughness measurement probes 37 are arranged in an equidistant circular ring distribution, and the second roughness measurement probe 37 is fixedly connected to the linkage bar 36.

[0040] The working principle of the precious metal jewelry detection device for overall detection of the present invention is as follows:

[0041] Step 1: During installation and placement, expansion bolts are inserted into the hole positions of the mounting plate 1 to fixedly install the mounting plate 1 on the ground hole positions. In this way, the mounting plate 1 can provide a supporting force for the support rod 17. The support rod 17 supports the controller 38, and the mounting plate 1 supports the support frame 16, and the support frame 16 supports the positioning disk 13. Then the precious metal seat 14 is moved downward, and the precious metal seat 14 drives the precious metal main jewelry 15 to move downward. The precious metal seat 14 is inserted into the inner wall groove of the positioning disk 13, and the precious metal main jewelry 15 and the precious metal seat 14 placed in a large piece can be placed at the designated detection position.

[0042] Step 2: During synchronous vertical roughness detection, the controller 38 is used to start the upward moving electric cylinder 2. The upward moving electric cylinder 2 pushes the linkage disk 3 upward. The linkage disk 3 drives a plurality of hinge shafts 4 to move upward. The plurality of hinge shafts 4 respectively drive the bottoms of a plurality of sleeve rods 5 to move upward synchronously. The sleeve rod 5 drives the push shaft 6 to move obliquely upward. The push shaft 6 drives the concave block 7 to move obliquely upward. At the same time, the concave block 7 drives the sliding frame 8 to move obliquely upward. The sliding frame 8 causes the socket slider 9 to move obliquely upward. The socket slider 9 moves obliquely upward along the inner wall of the inclined frame 11, and the socket slider 9 moves obliquely upward along the outer wall of the inclined column 10. At the same time, the positioning disk 13 supports the bracket 12, and the bracket 12 supports the inclined frame 11 to increase the stability of the inclined frame 11.

[0043] Meanwhile, the sliding frame 8 drives the displacement screw 19 to tilt and move upward. The sliding frame 8 tilts and moves upward along the gap between the limit frame 18 and the inclined frame 11, and the inclined frame 11 supports the limit frame 18 to increase the stability of the limit frame 18. The displacement screw 19 drives the threaded sleeve block 22 to tilt and move upward. The threaded sleeve block 22 causes the sleeve 24 to tilt and move upward. The sleeve 24 drives the first roughness measurement probe 25 to tilt and move upward. The first roughness measurement probe 25 performs distance sensing on the irregular inclined surface of the outer surface of the precious metal seat 14. When the distance value sensed by the first roughness measurement probe 25 is within the distance value range set by the controller 38, the roughness of the irregular inclined surface of the outer wall of the precious metal seat 14 is within the qualified range. When the distance value sensed by the first roughness measurement probe 25 is not within the distance value range set by the controller 38, the roughness of the irregular inclined surface of the outer wall of the precious metal seat 14 is in an unqualified state. Synchronous vertical roughness detection is performed on multiple irregular inclined surfaces of the outer wall of the precious metal seat 14.

[0044] Step 3: During synchronous horizontal displacement roughness detection, when the sliding frame 8 tilts and moves upward, the controller 38 starts multiple displacement motors 20. The multiple displacement motors 20 respectively drive the multiple displacement screws 19 to rotate forward. Meanwhile, the sliding frame 8 supports the support block 21, and the support block 21 supports the displacement motor 20 to increase the stability of the displacement motor 20. At the same time, the displacement screw 19 drives the threaded sleeve block 22 to move rightward under the action of the thread driving force. The threaded sleeve block 22 moves rightward along the inner wall of the sliding frame 8, and the threaded sleeve block 22 drives the connecting block 23 to move rightward. The connecting block 23 drives the sleeve 24 to move rightward. The sleeve 24 drives the first roughness measurement probe 25 to move rightward. At the same time, the two horizontal displacement distance sensors 26 move rightward. The horizontal displacement distance sensors 26 drive the vertical displacement distance sensors 27 to move rightward. The right horizontal displacement distance sensor 26 performs distance sensing on the right side inner wall of the limit frame 18. When the distance sensed by the right horizontal displacement distance sensor 26 is the same as the displacement distance set by the controller 38, the controller 38 starts the displacement motor 20 to drive the displacement screw 19 to rotate reversely.

[0045] The displacement screw 19 drives the threaded sleeve block 22 to move leftward under the action of the threaded transmission force. At the same time, the threaded sleeve block 22 drives the connecting block 23 to move leftward, and the connecting block 23 causes the sleeve 24 to move leftward. The sleeve 24 drives the first roughness measurement probe 25 to move leftward. The first roughness measurement probe 25 performs a lateral displacement movement detection on the irregular inclined surface of the outer wall of the precious metal seat 14. At the same time, the lateral displacement distance sensor 26 on the left side senses the distance of the left side surface of the inner wall of the limit frame 18. When the distance value sensed by the lateral displacement distance sensor 26 on the left side is the same as the distance set by the controller 38, the displacement motor 20 is continued to drive the displacement screw 19 to rotate forward. In this way, the connecting block 23 can perform irregular reciprocating displacement movements left and right on the inner wall of the limit frame 18, and at the same time, the connecting block 23 will also move upward. When the lateral displacement distance sensor 26 drives the vertical displacement distance sensor 27 to move upward, the vertical displacement distance sensor 27 will sense the distance from the top end of the inner wall of the limit frame 18.

[0046] Step 4: During the top synchronous roughness detection, when the sliding frame 8 tilts and moves upward, the linkage disk 3 drives the fixed block 28 to move upward. The fixed block 28 drives the rotating motor 29 to move upward. At the same time, the rotating motor 29 drives the rotating shaft 30 to move upward. The rotating shaft 30 causes the socket rotating block 32 to move upward. The socket rotating block 32 drives the connecting bar 33 to move upward. The connecting bar 33 drives the turntable 34 to move upward. In this way, the turntable 34 can drive a plurality of linkage rods 35 to move upward synchronously. The linkage rods 35 drive the linkage bar 36 to move upward. The linkage bar 36 causes the second roughness measurement probe 37 to move upward. A plurality of second roughness measurement probes 37 perform synchronous upward movement detection on the outer wall of the precious metal main ornament 15.

[0047] At the same time, the rotating motor 29 drives the rotating shaft 30 to rotate counterclockwise by 110 degrees. The rotating shaft 30 drives the socket rotating block 32 to rotate counterclockwise by 110 degrees. The socket rotating block 32 drives the connecting bar 33 to rotate counterclockwise by 110 degrees. The connecting bar 33 causes the turntable 34 to rotate counterclockwise by 110 degrees. The turntable 34 rotates counterclockwise by 110 degrees on the linkage disk 3. The turntable 34 drives a plurality of linkage rods 35 to rotate counterclockwise by 110 degrees. The linkage rods 35 drive the linkage bar 36 to rotate counterclockwise by 110 degrees. The linkage bar 36 causes the second roughness measurement probe 37 to rotate counterclockwise by 110 degrees.

[0048] When the angle sensed by the angle sensor 31 is -110 degrees, the rotation motor 29 is continued to be started by the controller 38 to drive the rotating shaft 30 to rotate clockwise by 110 degrees. The rotating shaft 30 drives the socket rotating block 32 to rotate clockwise by 110 degrees. The socket rotating block 32 drives the connecting bar 33 to rotate clockwise by 110 degrees. The connecting bar 33 causes the turntable 34 to rotate clockwise by 110 degrees. The turntable 34 drives a plurality of linkage rods 35 to rotate clockwise by 110 degrees. The linkage rods 35 drive the linkage bar 36 to rotate clockwise by 110 degrees. The linkage bar 36 causes the second roughness measurement probe 37 to rotate clockwise by 110 degrees. In this way, a plurality of second roughness measurement probes 37 can perform reciprocating lateral movement while moving upward, and can simultaneously detect the roughness of different points on the outer wall of the precious metal main ornament 15. In this way, the roughness of multiple points on the outer wall of the precious metal main ornament 15 on the top of the precious metal seat 14 can be synchronously detected. When the distance value sensed by the second roughness measurement probe 37 is within the range value set by the controller 38, the roughness of the precious metal main ornament 15 is in a qualified state. When the distance value sensed by the second roughness measurement probe 37 is not within the roughness range set by the controller 38, the roughness of the outer wall of the precious metal main ornament 15 is unqualified. When the distance value sensed by the vertical displacement distance sensor 27 is the same as the distance value set by the controller 38, the upward moving electric cylinder 2 is closed by the controller 38, and at the same time, a plurality of displacement motors 20 are closed.
