Description

Technical Field

[0001] This invention relates to the field of automated inspection equipment technology, specifically a multi-dimensional automated inspection device for workpieces. Background Technology

[0002] To ensure the quality of the workpieces, it is necessary to inspect the processed workpieces in a timely manner to identify defective pieces. For cylindrical workpieces, end face and cylindrical surface inspection mechanisms are required to inspect the outer surface, such as the outer surface hole diameter, groove, coaxiality, etc.; coaxial line spectral inspection mechanism is used to inspect the chamfer angle and step depth; endoscopic inspection mechanism is used to inspect the inner diameter, hole depth, inner step and inner wall quality of threaded holes; go and no-go gauge inspection mechanism is used to calibrate go and no-go gauges; finally, multi-dimensional inspection of the workpiece is completed.

[0003] Different features need to be detected separately on different devices. In order to improve the automation of detection, multiple robotic arms are used to transport the workpiece from one detection mechanism to the next. The control of the robotic arms requires higher precision. The robotic arms clamping the workpiece multiple times and positioning it on the fixture will cause error accumulation, which will eventually affect the accuracy of detection.

[0009] Furthermore, the clamping assembly includes a base four, a clamping plate one, a clamping plate two, and a self-locking component; The base four is connected to the corresponding drive end of the power component one.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] See Figures 1-13 The present invention provides a technical solution: a multi-dimensional automated inspection device for workpieces, including a worktable 11, on which a closed-loop slide rail 13 and a power component are provided; on one side of the closed-loop slide rail 13, an end face inspection mechanism 14, a cylindrical surface inspection mechanism 15 moving along the length direction of the closed-loop slide rail 13, a spectral inspection mechanism 12, and an endoscope inspection mechanism 16 moving along the width direction of the closed-loop slide rail 13 are sequentially provided; the device further includes: The clamping assembly 2, which is used to clamp the column, is provided in several parts and is located at the top of the workbench 11. The corresponding drive end of the power component is connected to the clamping assembly 2 and is used to drive the clamping assembly 2 to move forward along the closed-loop slide rail 13. The go / no-go gauge inspection mechanism 17 is set on the workbench 11 and is opposite to the endoscope inspection mechanism 16. The clamp assembly 2 moves from the closed-loop slide rail 13 between the two. The material discharge port 3 is located on the workbench 11; The flipping component 4 is set on the worktable 11 and moves along the width direction of the closed-loop slide rail 13, located in the middle of the corresponding go / no-go gauge detection mechanism 17 inside the closed-loop slide rail 13; during endoscopy inspection, it is used to drive the column 1 to rotate around the endoscope as the center line; after endoscopy inspection, the flipping component 4 drives the column 1 held at its end to rotate upward to the go / no-go gauge detection mechanism 17 for inspection; then it drives the column 1 to rotate to the discharge port 3 for material discharge.

[0020] It should be noted that when installing the workbench 11, space needs to be left below the unloading port 3 for the installation of an external feeding device; the closed-loop slide rail 13 is laid on the workbench 11 to form an elliptical or racetrack-shaped circulating track; the first power component is a combination of a motor and chain, or a motor and a synchronous belt, which is existing technology and not shown in the figure. The first power component drives the clamping assembly 2 to continuously circulate along the track; a closed-loop streamline layout is achieved, and all inspection items are completed in one clamping of the workpiece, with no error accumulation; there is no robotic arm transfer error, and the positioning consistency is high, making it suitable for large-scale precision inspection; the entire process is equipped with a PLC control system, which automatically records inspection data and outputs qualified / unqualified signals.

[0021] In one embodiment, the cylindrical surface detection mechanism 15 includes an adjustment component 150 and an inner clamping component 151. The adjustment component 150 includes a telescopic member 1501, a connecting plate 1502, and a motor 1503. A base 1504 is provided on the worktable 11. The telescopic member 1501 is fixed to the top of the base 1504. The connecting plate 1502 is fixed to the driving end of the telescopic member 1501. The motor 1503 is fixed to the connecting plate 1502. The inner clamping assembly 151 includes a double-headed telescopic member 1511 and two inner clamping blocks 1512. The double-headed telescopic member 1511 is vertically arranged at the drive end of the motor 1503. The two inner clamping blocks 1512 are respectively fixed on the two drive ends of the double-headed telescopic member 1511 and are used to abut against the inner wall of the through hole of the column member 1.

[0022] In one embodiment, the flipping assembly 4 includes a third base 41, a second base 42, an adjustment assembly 43, a clamping seat 44, an outer clamping block 45, and a third motor 46. The third base 41 is located on the worktable 11 and moves along the width direction of the closed-loop slide rail 13. The third motor 46 is located at the top of the third base 41. The output shaft of the third motor 46 is provided with the second base 42. The second adjustment assembly 43 is fixedly provided on the second base 42. The second adjustment assembly 43 has the same structure as the first adjustment assembly 150 but different specifications. That is, the second adjustment assembly 43 also includes a telescopic member 1501, a connecting plate 1502, and a motor 1503. In the second adjustment assembly 43, the telescopic member 1501 is fixed on the second base 42. The driving end of the telescopic member 1501 is fixed to the connecting plate 1502. The motor 1503 is fixed on the connecting plate 1502. The output shaft of the motor 1503 of the second adjustment assembly 43 is connected to the clamping seat 44. The output end of the adjustment component 43 is equipped with the clamping seat 44. Two outer clamping blocks 45 are symmetrically arranged on the clamping seat 44, and the two outer clamping blocks 45 are close to or far from each other on the clamping seat 44.

[0023] With this design, the flipping component 4 is located between the endoscope inspection mechanism 16 and the go / no-go gauge inspection mechanism 17, and is responsible for rotating the endoscope, reversing the go / go gauge, and turning the material for feeding. Two electric push rods are arranged opposite each other in the clamping seat 44. The driving end of the electric push rod is connected to the outer clamping block 45 and is used to drive the two outer clamping blocks 45 to move closer or further apart on the clamping seat 44.

[0024] In one embodiment, the device further includes: The clamping force application component 5 is located on the edge of the worktable 11 near the end face detection mechanism 14, and is used to push the corresponding clamping component 2 to clamp the column 1. The unloading component 6 is set on the workbench 11, with one set at each of the cylindrical surface detection mechanism 15 and the endoscope detection mechanism 16, and is used to open the clamping assembly 2 to release the cylindrical component 1.

[0025] In one embodiment, the clamp assembly 2 includes a base four 20, a clamping plate one 21, a clamping plate two 22, and a self-locking component 23; The base four 20 is connected to the corresponding drive end of the power component one. The clamping plate one 21 and the clamping plate two 22 are oppositely arranged at the top of the base four 20. The clamping plate one 21 is arranged along the width direction of the closed-loop slide rail 13. The clamping plate two 22 is provided with a V-shaped clamping groove one 24 with an opening facing the clamping plate one 21. The clamping plate two 22 is close to or away from the clamping plate one 21 along the length direction of the closed-loop slide rail 13. The base four 20 is provided with an upward-opening adjustment groove 25 along the moving direction of the clamping plate two 22. The self-locking member 23 is located in the adjustment groove 25. The self-locking member 23 is used to fix the position of the clamping plate two 22 on the base four 20.

[0026] This design, through the cooperation of the horizontally placed V-shaped clamping groove 24 and the clamping plate 21, ensures that the clamping column 1 is parallel to the endoscope's path each time, and that the center of each column 1 is at the same height.

[0027] In one embodiment, the self-locking component 23 includes a rack 230, a first bracket 231, a first side plate 232, a second side plate 233, a spur gear 234, a first rotating shaft 235, a second rotating shaft 236, a control plate 237, a pawl 238, a first spring 239, a second spring 2310, and a ratchet 2311; The rack 230 is arranged in the adjustment groove 25 along the length direction of the closed-loop slide rail 13. The bracket 231 and the side plate 232 are both located at the bottom end of the clamping plate 22. The rotating shaft 235 is rotatably mounted on the clamping plate 22 along the width direction of the closed-loop slide rail 13. The ratchet 2311 and the sprocket 234 are fixed side by side on the rotating shaft 235. The sprocket 234 meshes with the rack 230. The bracket 231 is equipped with a rotating shaft 236. The control plate 237 and the pawl 238 are fixed at both ends of the rotating shaft 236 respectively. The bracket 231 is connected to the bottom of the pawl 238 by a spring 239. Under the action of the spring 239, the pawl 238 is engaged with the ratchet 2311 and can only move forward and cannot move back, realizing one-way self-locking clamping. When the control plate 237 with the inclined surface 26 is lifted by the force relief component 6, it drives the pawl 238 to disengage from the ratchet 2311, and the clamping assembly 2 is unlocked and released.

[0028] The bottom end of the clamping plate 21 is provided with a side plate 233, and the side plate 232 is connected to the side plate 233 by a spring 2310. The unloading component 6 drives the control board 237 to rotate after passing through the base 20.

[0029] In the existing technology, cylindrical workpieces are mostly divided into two types: one is a single cylinder without a base, and the other is a single cylinder with a base. Depending on the processing requirements, the end of the workpiece with the base may be heavier, which makes the existing fixtures unable to adapt to the diversity of cylindrical workpieces. Consequently, they cannot stably and accurately position different cylindrical workpieces, further affecting the accuracy of the inspection.

[0030] This design allows for adaptive clamping of cylindrical workpieces with bases and eccentricity. Because the clamping plate 22 has a V-shaped clamping groove 24 with its opening facing the clamping plate 21, as long as the outer radius of the column 1 is within the working range, after the column 1 is clamped by the clamping assembly 2, the center of the column 1 will coincide with the axis of symmetry of the V-shaped clamping groove 24. In other words, after the clamping assembly 2 clamps the column 1, the centers of the column 1 with different outer radii will be at the same height, improving the adaptability of various detection mechanisms with the clamping assembly 2 and the column 1. The detection mechanism does not need to adjust its height according to the inner and outer diameter specifications of the column 1, reducing the use of power.

[0031] In one embodiment, the control plate 237 is provided with an inclined surface 26, and the base 20 is provided with a through hole 27 on the side near the adjustment groove 25. The unloading component 6 passes through the through hole 27 and abuts against the inclined surface 26 to drive the control plate 237 to rotate away from the ratchet 2311.

[0032] With this design, after the clamp assembly 2 reaches the corresponding unloading assembly 6, the unloading assembly 6 is inserted into the through hole 27, and after contacting the inclined surface 26, it continues to be inserted, lifting the control plate 237. The control plate 237 drives the pawl 238 to rotate synchronously through the rotating shaft 236 and disengage from the ratchet 2311, thus unlocking and releasing the clamp assembly 2.

[0033] In one embodiment, the clamping force application assembly 5 includes a second bracket 50, a third rotating shaft 51, a pusher 52, and a second power component. Several third rotating shafts 51 are provided, all located on the bracket. One third rotating shaft 51 is distributed at each of the end face detection mechanism 14, the cylindrical surface detection mechanism 15, and the endoscope detection mechanism 16. A pusher 52 is fixed to each third rotating shaft 51 for pushing the corresponding second clamping plate 22 closer to the first clamping plate 21. The second power component is located within the second bracket 50 for driving the third rotating shafts 51 to rotate. The second power component adopts a combination structure of a motor, conveyor belt, and pulleys, which can control all the third rotating shafts 51 to rotate simultaneously or control several third rotating shafts 51 to rotate separately. When rotating simultaneously, the detection time and interval time at several detection stations must be coordinated.

[0034] With this design, the second power component drives the third shaft 51 to rotate, the pusher 52 swings outward, pushes the second clamping plate 22 to move towards the first clamping plate 21, and completes automatic clamping. Then the self-locking component 23 locks it in place.

[0035] In one embodiment, the force-relieving assembly 6 includes a plurality of telescopic members 60 disposed on the worktable 11. One telescopic member 60 is distributed at both the cylindrical surface detection mechanism 15 and the endoscope detection mechanism 16. The driving end of the telescopic member 60 is used to pass through the through hole 27.

[0036] In one embodiment, the outer clamping block 45 is provided with a V-shaped clamping groove 48 for clamping the end of the column member 1.

[0037] In one embodiment, telescopic member 1501 and telescopic member 60 are cylinders or electric push rods.

[0038] Specific usage process: Step 1, Loading and Automatic Clamping: At the loading position, a manual / robotic arm places a column 1 into the first clamping assembly 2. The first clamping assembly 2 moves with the closed-loop slide rail 13 to the first clamping force application assembly 5. The first pusher 52 rotates downward to fit against the clamping plate 22, pushing the clamping plate 22 to clamp the column 1. As the clamping plate 22 moves closer to the clamping plate 21, the pawl 238 of the self-locking component 23 engages with the ratchet 2311, locking in one direction and preventing loosening. Therefore, the clamping plate 22 can only move closer to the clamping plate 21 and cannot move away. After clamping by the clamping assembly 2, the centers of columns 1 with different outer radii are at the same height, improving the compatibility of various detection mechanisms with the clamping assembly 2 and the column 1. In scenario one, column 1 is a single cylinder without a base; in scenario two, column 1 is a single cylinder with a base. When placing column 1 onto clamp assembly 2, in both cases, the cylinder body is placed between clamping plate 22 and clamping plate 21. In scenario two, the base is pre-installed on the outside of clamping plate 22 and clamping plate 21, and the base is located on the side of clamping plate 22 away from the endoscope inspection mechanism 16. This allows for the adaptation of columnar workpieces with and without bases, and for those with uneven weight, ensuring stable and non-eccentric clamping.

[0039] Step 2, end face inspection: The fixture assembly 2 drives the column 1 into the end face inspection mechanism 14 to complete the inspection of the end face flatness, outer diameter, and groove size; Step 3, Automatic clamping and rotation of the inner support for cylindrical surface detection: The clamping assembly 2 reaches the cylindrical surface detection mechanism 15. The inner clamping block 1512 of the cylindrical surface detection mechanism 15 extends into the inner through hole one of the cylindrical member 1. The two driving ends of the double-headed telescopic member 1511 drive the two inner clamping blocks 1512 to bidirectionally support the inner wall of the cylindrical member 1. After obtaining the inner support, the force relief assembly 6 is inserted into the second through hole 27. After contacting the inclined surface 26, it continues to insert, lifting the control plate 237, and the clamping assembly 2 is unlocked and released. The elastic force of the second spring 2310 drives the first side plate 232 and the second clamping plate 22 away from the first clamping plate 21. After losing the clamping force, the first motor 1503 drives the cylindrical member 1 to rotate 360°, completing the detection of the outer surface hole diameter and inner wall size of the cylindrical surface. After the detection is completed, the inner support is released, and the clamping force application assembly 5 drives the clamping assembly 2 to return to its original position. Step 4, Spectral Detection: Column 1 enters the spectral detection mechanism 12 to complete non-contact detection of inner diameter, chamfer angle, and step depth; Reference Figure 1 , Figure 5 and Figure 11 The cylindrical surface detection mechanism 15 and the spectral detection mechanism 12 are mounted on the same support frame and can move left and right and up and down along the support frame. This is existing technology and will not be described in detail here. Step 5: Endoscope inspection and rotation of the rotating endoscope assembly: The column 1 reaches the endoscope inspection mechanism 16, and the endoscope extends into the hole; by adjusting the telescopic component 1501 of component two 43, the outer clamping block 45 is driven to approach the column 1, and the outer clamping block 45 clamps the end of the workpiece. The clamping cylinder body is without a base, and the clamping base is with a base; the unloading component 6 at this point is inserted into the through hole 27, and continues to be inserted after contacting the inclined surface 26. The clamping component 2 is unlocked and released. The motor 1503 of component two 43 drives the clamping seat 44, the outer clamping block 45 and the column 1 to slowly rotate 360 ​​degrees. The endoscope takes a full-circumference image of the inner wall of the hole, such as detecting threads, defects, steps and depth. Step 6: Go / No-Go Gauge Inspection and Reversal: After endoscopy, motor 346 drives column 1 to rotate upwards by 90°, sending column 1 into the go / no-go gauge inspection mechanism 17 to complete the calibration of the bore diameter go gauge and no-go gauge; Reference Figure 5 As can be seen, the entire flipping assembly 4 can be moved along the width direction of the worktable 11 by the base 3 41, thereby adapting to the position of the two sets of inspection heads in the go and no-go gauge inspection mechanism 17; and the angle and height of the column 1 can be further adjusted by adjusting the assembly 2 43. Step 7, Automatic Unloading: After the go / no-go gauge inspection is completed, the flipping component 4 continues to rotate to above the unloading port 3, the outer clamp 45 is released, and the workpiece falls into the unloading port 3, completing the entire inspection process; the flipping component 4 realizes three functions: rotational endoscopy, reversing go / go gauge, and turning unloading, with a simplified structure and fast cycle time; Step 8, Fixture Return: The empty fixture returns to the loading position along the closed-loop slide rail 13 and enters the next cycle. This achieves cyclical movement, automatic clamping, automatic release, automatic flipping, and automatic unloading, enabling unmanned operation, eliminating robotic arm transfer errors, and ensuring high positioning consistency, making it suitable for large-volume precision testing.

[0040] Among them, the V-groove 24 of the clamping plate and the V-groove 48 of the clamping plate are covered with wear-resistant nylon, which does not damage the surface of the workpiece.

[0041] The above description is only a preferred embodiment of the present invention and is 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 within the protection scope of the present invention.

[0042] It should be noted that if the embodiments of the invention involve directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0043] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B. Additionally, if the embodiments of the invention involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, "several" refers to two or more.

[0044] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the invention.
