Description

Technical Field

[0001] This invention belongs to the field of automated testing technology, specifically relating to an automated testing device for gear shaft components. Background Technology

[0002] A gear shaft component is a hollow structure with a threaded hole in the middle, including a gear part in the middle and shaft parts on both sides. After processing, it is necessary to strictly test many parameters, including gear thickness, outer diameter, thread go / no-go gauge, inner diameter, etc. After testing, it is cleaned, rust-proofed and qualified products are sorted.

[0003] Currently, the industry generally adopts the following two methods for the inspection and post-processing of gear shaft components:

[0004] One method is manual, step-by-step operation. Operators use calipers, thread gauges, and micrometers to inspect each parameter of the gear shaft components one by one. After inspection, cleaning, oiling, and sorting are done manually. This method has the following drawbacks: low inspection efficiency, making it difficult to meet the needs of mass production; inspection results are greatly affected by the operator's skill level and subjective judgment; and multiple processes are carried out separately with many intermediate transfer links, making it easy for products to be damaged or confused due to impacts.

[0005] The second method involves cascading multiple machines. This method arranges several single-function machines, such as thickness gauges, outer diameter measuring instruments, thread inspectors, inner diameter inspectors, cleaning machines, oil impregnation machines, and sorting machines, in sequence, with products transferred between the machines manually or via conveyor lines. While this method achieves a degree of mechanization, it still has the following drawbacks: large equipment footprint, high total purchase cost, lengthy production line layout, lack of coordination between machines, requiring multiple personnel for operation and maintenance, and high labor costs.

[0006] In summary, existing methods for inspecting and processing gear shafts suffer from problems such as low integration, low automation, insufficient inspection accuracy, fragmented processes, and low efficiency. There is an urgent need for a fully automated device that can integrate multiple inspection, cleaning, oiling, and sorting functions to improve production efficiency and quality control. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution.

[0008] An automated inspection device for gear shaft components is disclosed. The gear shaft component to be inspected is a hollow structure with a threaded hole in the middle, including a gear portion in the middle and shaft portions on both sides. The automated inspection device includes: a loading station with a first material tray and a loading and conveying mechanism; a tooth thickness inspection station with a first positioning mechanism and a tooth thickness vision inspection module; an outer diameter inspection station with a second positioning mechanism and an outer diameter vision inspection module; a go gauge inspection station with a third positioning mechanism and a go gauge inspection module; a no-go gauge inspection station with a fourth positioning mechanism and a no-go gauge inspection module; an inner diameter inspection station with a fifth positioning mechanism and an inner diameter inspection module; a cleaning station with a sixth positioning mechanism and a cleaning mechanism; an oil immersion station with an oil immersion mechanism; and a sorting and unloading station with a qualified product tray, a non-qualified product tray, and a sorting robot arm. The first, second, third, fourth, fifth, and sixth positioning mechanisms are used to position the gear shaft component. The gear shaft components are transferred between the stations via a transfer mechanism.

[0009] Furthermore, the first positioning mechanism includes a first lateral movement module and a first fixed base. The first fixed base is connected to the output end of the first lateral movement module, and the first fixed base is provided with a first positioning groove for accommodating the shaft portion of one side of the gear shaft. The first lateral movement module is used to drive the first fixed base to move into the detection area of ​​the tooth thickness visual inspection module. The tooth thickness visual inspection module is a 3D camera.

[0010] Furthermore, the first positioning mechanism also includes a flipping module, which includes a first lifting cylinder, a first rotating cylinder, and a flipping gripper.

During inspection, a gear shaft is sleeved on the second positioning shaft, and the positioning gripper clamps a shaft portion, with the end face of the shaft portion abutting against the upper surface of the second positioning beam. The outer diameter visual inspection module is mounted on the second mounting bracket and located directly above the second positioning beam.

[0012] Furthermore, the outer diameter detection station is also equipped with a lateral vision detection module, which is located on the side of the second mounting bracket and is used to detect the overall length and coaxiality of the gear shaft.

[0013] Furthermore, the sixth positioning mechanism includes a sixth mounting bracket, a sixth transverse cylinder, a sixth slide block, and a collection pipe.

The sixth slide block is provided with a positioning groove for placing the gear shaft, and a venting groove and an annular sealing groove are provided around the positioning groove. The venting groove communicates with the collection pipe.

[0014] The cleaning mechanism includes a sixth lifting module and an air blowing hood. The air blowing hood is installed at the output end of the sixth lifting module and connected to an external air pump. During cleaning, the sixth lifting module drives the air blowing hood to descend until it closes with the sealing groove.

[0015] Furthermore, the oil immersion mechanism includes a seventh mounting frame, a seventh lifting module, a connecting plate, a mandrel, and an oil box. The seventh lifting module is mounted on the seventh mounting frame, the connecting plate is mounted on the output end of the seventh lifting module, and the mandrel is mounted on the connecting plate for mounting the gear shaft.

Furthermore, terms such as first, second, etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features shown. In the description of this invention, unless otherwise expressly specified and limited, terms such as installation, connection, linking, etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] refer to Figures 1 to 16 This embodiment provides an automated inspection device for gear shaft components, used for fully automated inspection, cleaning, oiling, and sorting of gear shaft components 130. The gear shaft component 130 to be inspected is a hollow structure with a threaded hole in the middle, including a gear portion in the middle and shaft portions on both sides.

[0026] The automated testing equipment includes a frame and, sequentially arranged on the frame, a loading station 100, a tooth thickness testing station 200, an outer diameter testing station 300, a go gauge testing station 400, a no-go gauge testing station 500, an inner diameter testing station 600, a cleaning station 700, an oil immersion station 800, and a sorting and unloading station 1000. The gear shafts 130 are automatically transported between the stations via a transfer mechanism 900.

[0027] refer to Figure 3 The loading station 100 is equipped with a first material tray 110 and a loading and conveying mechanism 120. The first material tray 110 is used to place the gear shaft 130 to be inspected, and the loading and conveying mechanism 120 is used to transport the gear shaft 130 from the first material tray 110 to the gear thickness inspection station 200.

[0028] Preferably, the loading station 100 is also equipped with a transverse sliding module 111. The first material tray 110 is installed at the output end of the transverse sliding module 111 and can move laterally under the drive of the transverse sliding module 111. The loading and conveying mechanism 120 includes a two-axis loading moving module 121 with longitudinal and lifting functions. The output end of the two-axis loading moving module 121 is equipped with a loading gripper 122. The two-axis loading moving module 121 drives the loading gripper 122 to move longitudinally, and cooperates with the transverse sliding module 111 to drive the first material tray 110 to move laterally, so that the loading gripper 122 can grasp the gear shaft 130 at any position on the first material tray 110 and transport it to the gear thickness detection station 200.

[0029] refer to Figure 4 and Figure 5The tooth thickness detection station 200 is equipped with a first positioning mechanism 210 and a tooth thickness visual detection module 230. The first positioning mechanism 210 is used to fix the gear shaft 130, and the tooth thickness visual detection module 230 is used to detect the thickness of the gear part.

[0030] In this embodiment, the first positioning mechanism 210 includes a first lateral movement module 211 and a first fixed base 212. The first fixed base 212 is connected to the output end of the first lateral movement module 211, and the first fixed base 212 is provided with a first positioning groove 7131 for accommodating the shaft portion of one side of the gear shaft 130. The first lateral movement module 211 is used to drive the first fixed base 212 to move into the detection area of ​​the tooth thickness visual inspection module 230. The tooth thickness visual inspection module 230 is a 3D camera.

[0031] To achieve high-precision detection of gear thickness and comprehensive evaluation of end-face parallelism, the first positioning mechanism 210 also includes a flipping module 220. The flipping module 220 includes a first lifting cylinder 221, a first rotating cylinder 222, and a flipping gripper 223. The first rotating cylinder 222 is connected to the output end of the first lifting cylinder 221, and the flipping gripper 223 is connected to the output end of the first rotating cylinder 222. In operation, the loading and conveying mechanism 120 places the gear shaft 130 into the first positioning groove 7131 of the first fixed seat 212. The first lateral movement module 211 drives the first fixed seat 212 to move to the detection area of ​​the 3D camera. The 3D camera performs a first measurement of the thickness of one side of the gear shaft 130, acquiring the first thickness data. Subsequently, the flipping module 220 is activated, flipping the gear shaft 130. The first lateral movement module 211 again drives the first fixed seat 212 to move to the detection area of ​​the 3D camera, and the 3D camera performs a second measurement of the other side of the gear shaft 130, acquiring the second thickness data.

[0032] The control system processes the first and second thickness data. Firstly, it calculates the average of the two measurements as the final tooth thickness detection result. Since single optical measurements are easily affected by factors such as lens distortion, light source uniformity, and product placement angle, averaging after flipping the measurement effectively eliminates random errors from a single measurement, significantly improving the accuracy and repeatability of tooth thickness detection. Secondly, it compares the first and second thickness data. If the difference between the two measurements is within a preset tolerance range, it indicates good parallelism of the two end faces of the gear and uniform thickness; if the difference exceeds a preset threshold, it indicates quality problems such as excessive end face parallelism or local deformation of the gear. This design allows the equipment to indirectly detect the parallelism and thickness uniformity of the gear end faces while simultaneously performing numerical tooth thickness detection, further expanding the coverage of detection items and ensuring product quality.

[0033] refer to Figure 6 and Figure 7The outer diameter inspection station 300 is equipped with a second positioning mechanism 310 and an outer diameter vision inspection module 320. The second positioning mechanism 310 is used to fix the gear shaft 130, and the outer diameter vision inspection module 320 is used to inspect the outer diameter (i.e., the tip circle diameter) of the gear part.

[0034] In this embodiment, the second positioning mechanism 310 includes a second mounting bracket 311, a second positioning beam 312, a second positioning shaft 313, and a positioning gripper 314. The second positioning beam 312 and the positioning gripper 314 are mounted on the second mounting bracket 311, and the second positioning shaft 313 is disposed on the second positioning beam 312. During outer diameter detection, the gear shaft 130 is sleeved on the second positioning shaft 313, and the positioning gripper 314 clamps one side of the shaft portion of the gear shaft 130, with the end face of the shaft portion abutting against the upper surface of the second positioning beam 312. The outer diameter visual inspection module 320 is mounted on the second mounting bracket 311 and located directly above the second positioning beam 312.

[0035] To further inspect other dimensional parameters of the gear shaft 130, a lateral vision inspection module 330 is also provided in the outer diameter inspection station 300. This lateral vision inspection module 330 is located on the side of the second mounting bracket 311 and is used to inspect the overall length and coaxiality of the gear shaft 130. During operation, after the positioning gripper 314 clamps and fixes the gear shaft 130, the outer diameter vision inspection module 320 acquires images from directly above to obtain the outer diameter dimension of the gear part; the lateral vision inspection module 330 acquires images from the side to obtain the overall length and coaxiality data of the gear shaft 130.

[0038] The fourth positioning mechanism has the same structure as the third positioning mechanism 410, and the no-go gauge detection module has a similar structure to the go gauge detection module 420. The difference is that the floating chuck 424 is equipped with a no-go gauge head.

[0039] During operation, the transfer mechanism 900 moves the gear shaft 130 to the third slide 412. The third clamping cylinder 415 drives two clamping blocks to fix the gear shaft 130, and the third transverse cylinder 413 drives the third slide 412 to move below the go gauge inspection module 420. The go gauge lifting module 421 drives the go gauge head 425 to descend, and the go gauge inspection motor 423 drives the go gauge head 425 to rotate. Under the floating action of the floating chuck 424, the go gauge head 425 engages with the threaded hole to prevent the thread from jamming. If the go gauge head 425 can rotate to the preset depth, the thread go gauge is deemed qualified; otherwise, it is deemed unqualified. After completing the go gauge inspection, the transfer mechanism 900 moves the gear shaft 130 to the no-go gauge inspection station 500, where the no-go gauge inspection module performs no-go gauge inspection in the same manner.

The inner diameter lifting module 621 drives the inner diameter detection head 623 to descend, and the two-part detector extends into the threaded hole. Its conical structure converts the change in hole diameter into the displacement of the measuring rod, and the inner diameter value is accurately read by the displacement sensor. The inner diameter detection module 620 can measure the upper and lower sections of the threaded hole separately to obtain complete hole diameter data.

[0043] refer to Figure 12 and Figure 13 The cleaning station 700 is equipped with a sixth positioning mechanism 710 and a cleaning mechanism 720.

[0044] In this embodiment, the sixth positioning mechanism 710 includes a sixth mounting bracket 711, a sixth transverse cylinder 712, a sixth slide block 713, and a collection pipe 714. The sixth slide block 713 is slidably mounted on the sixth mounting bracket 711, and the sixth transverse cylinder 712 is fixed on the sixth mounting bracket 711, with its piston rod connected to the sixth slide block 713.

The air pump starts, and the air blowing pipe in the air blowing hood 722 blows high-pressure air onto the inner hole and outer surface of the gear shaft 130 to remove impurities adhering during the inspection process. The blown-off waste enters the collection pipe 714 through the ventilation groove 7132 and is collected by the waste collection device.

[0048] During operation, the transfer mechanism 900 places the gear shaft 130 onto the mandrel 814. The seventh lifting module 812 drives the connecting plate 813 and the mandrel 814 to descend, immersing the gear shaft 130 in the anti-rust oil in the oil box 815, completing the oil immersion operation. After the seventh lifting module 812 drives the mandrel 814 to rise, the double-rod telescopic cylinder 821 drives the sponge blocks 822 on both sides to close in the middle, absorbing oil from the surface of the gear shaft 130 and preventing excessive oil residue.

The qualified product trays include a second tray 1020 and a fourth tray 1040, while the unqualified product trays include a third tray 1030 and a fifth tray 1050. The second and third trays 1020 are chute-type trays with several parallel tracks, while the fourth and fifth trays 1040 and 1050 are trough-type trays with evenly distributed placement slots, each slot holding only one gear shaft 130. Users can choose between chute-type or trough-type trays for unloading according to product specifications or packaging requirements.

[0051] During operation, the test results from each inspection station are transmitted to the control system. The sorting robotic arm 1010 picks up the gear shaft 130 based on the test results and places it into the corresponding qualified or unqualified product tray.
