[0024] The hardness detection mechanism of the present invention also includes a vertical cylinder 29, a cylinder support frame 6 and a tray support 26, wherein the vertical cylinder 29 is arranged on the top of the cylinder support frame 6, wherein the tray support 26 is fixedly connected to the lifting end of the vertical cylinder 29, and a pulley 28 is rotatably arranged on the tray support 26; wherein the traction mechanism includes a horizontal telescopic cylinder and a traction plate 3, wherein the horizontal telescopic cylinder is arranged on the cylinder support frame 6; wherein the traction plate 3 is fixedly connected to the telescopic end of the horizontal telescopic cylinder, and a block 3a is arranged on the bottom surface of the traction plate 3, and the bottom of the block 3a is higher than the height of the top of the slot 32; the tray 27 is provided with a positioning groove; a blocking cylinder 7 matching the positioning groove is also fixedly arranged on the cylinder support frame 6, wherein an installation opening is provided on the top of the hardness detection bracket 2, and the hardness detector 1 is arranged at the installation opening of the hardness detection bracket 2.

This design ensures the accuracy of the movement of the object to be detected. At the same time, the application of the lotus-type cylinder makes the entire transportation process smoother.

[0025] The hardness testing mechanism of the present invention has a testing state and a specimen returning state. In the testing state, the blocking cylinder 7 is in contact with the positioning groove of the tray 27, completing the calibration of the position of the tray 27, and the vertical cylinder 29 can drive the tray bracket 26 to lift the tray 27, completing the calibration of the position of the tray 27, the bottom of the tray 27 is slidably connected with the pulley 28, the slot 32 of the tray 27 is engaged with the block 3a, and the horizontal telescopic cylinder can pull the tray 27 onto the testing platform; in the specimen returning state, the horizontal telescopic cylinder can pull the tray 27 onto the tray bracket 26, and the bottom of the tray 27 is in contact with the pulley 28, and the vertical cylinder 29 drives the pallet to descend, so that the tray 27 is placed on the horizontal conveying mechanism.

[0026] The hardness detection bracket 2 of the present invention has a mounting opening at the top; wherein the hardness detector 1 comprises a hardness detector body, a hardness detection drive motor 100, a hardness probe 101, an eyepiece 102 and a rotating bracket 103, wherein the hardness detector body is fixed to the mounting opening of the hardness detection bracket 2 through a connecting piece, so that the middle part of the hardness detector body is fixed at the mounting opening; wherein the hardness detection drive motor 100 is arranged at the top of the hardness detector body, wherein the hardness probe 101 and the eyepiece 102 are arranged at the bottom of the hardness detector body through the rotating bracket 103; The hardness probe 101 and the eyepiece 102 are fixed under the hardness detection bracket 2, and the hardness detection drive motor 100 is connected to the hardness probe 101 and the eyepiece 102 through the rotating bracket 103. Specifically, the hardness detector 1 is also electrically connected to a display, which is used to display the detection data of the hardness detector 1, so as to assist manual hardness test result judgment.

This innovative technology not only improves the accuracy and reliability of measurement results, but also reduces production costs for enterprises and enhances market competitiveness.

[0027] The specific operation process of the present invention is as follows: like Figure 1 As shown, before starting the device, the sample to be tested should be placed on the lower layer of the transmission assembly line. The sample to be tested is placed in the clamp frame 501 above the tray 27, and the clamping hoop 500 is lowered to fix the sample to be tested in the clamp of the clamp frame. After ensuring that the sample to be tested is completely fixed, the tray 27 with the fixed sample to be tested is placed in the lower layer of the horizontal conveying mechanism.

[0028] The device is started, and the horizontal transmission drive motor 9 moves the tray 27 in the transmission assembly line. When the moving tray 27 is transported to the lifting mechanism, the drive motor 18 drives the active bevel gear 20 to rotate, so that the active bevel gear 20 drives the driven bevel gear 21 to rotate, and the driven bevel gear 21 rotates to drive the connecting rod 23, and the connecting rod 23 drives the belt 24 to rotate through the small roller 25 so that the tray 27 completely enters the lifting mechanism, such as Figure 2 shown.

[0029] like Figure 2As shown, in the lifting mechanism, the gear 12 is located on the hydraulic rod 10 and connected by the top rod 11, and the two chains 13 are respectively meshed with the two sides of the gear 12. The lower end of the chain 13 is fixed concentrically by the chain connecting shaft 14, and the chain connecting shaft 14 is fixed to the connecting plate 15 through the guide bracket 16. Driving the hydraulic rod 10 to rise drives the chain 13 on the gear 12 to rotate and then drives the lower chain connecting shaft 14 to rotate. The chain connecting shaft 14 drives the guide bracket 16 to perform the lifting function through the connecting plate 15, thereby driving the tray 27 to rise. The driving motor 18 drives the active bevel gear 20 to rotate, so that the active bevel gear 20 drives the driven bevel gear 21 to rotate, and the driven bevel gear 21 rotates to drive the connecting rod 23. The connecting rod 23 drives the belt 24 to rotate through the small roller 25 so that the tray 27 enters the upper part of the transmission assembly line. The horizontal transmission drive motor 9 drives the tray 27 to move to the inspection area on the upper layer of the horizontal conveying mechanism.

[0030] like Figure 5 The pulley 28 is installed on both sides of the tray bracket 26, and the tray 27 is placed on the pulley of the pulley 28; the blocking cylinder 7 is connected to the left side of the cylinder support frame 6 through screws, and the top card of the blocking cylinder 7 cooperates with the positioning groove on the left side of the tray 27. The top card of the blocking cylinder 7 can only be moved up and down by the cylinder. When the card is lifted up by the cylinder, it cooperates with the positioning groove to complete the braking of the tray 27, so that the tray 27 can be accurately pulled horizontally to the detection area for detection. Specifically, the blocking cylinder 7 is a TWH blocking cylinder produced by AirTac.

[0031] As shown in the figure, the vertical cylinder 29 below the inspection area pushes up to drive the tray bracket 26 to rise, thereby driving the tray 27 to rise, and the card slot 32 is connected to the traction plate 3 through the pull block 3a. The lotus-shaped cylinder 4 drives the traction plate 3 to slide along the guide rail, and the traction plate drives the tray 27 to slide along the pulley 28 on the tray bracket 26 to the hardness detection position through the pull block 3a.

[0032] like Figure 5 As shown, the hardness test motor 100 drives the hardness test probe 101 to move downward, contact and slowly squeeze the sample to be tested downward. After a certain period of time, the hardness test motor 100 drives the hardness detection probe 101 to lift a certain distance. At this time, a tiny pit is formed on the surface of the sample to be tested. The conversion lens function is completed by the rotating shaft 103, and the hardness test head 101 is converted to the optical mirror 102. The optical mirror collects the diameter of the small pit on the surface of the sample to be tested. The hardness of the sample to be tested is calculated by detecting the diameter of the small pit, and the object to be tested is evaluated whether it is qualified. After the test is completed, the rotating shaft 103 is turned back to the hardness probe, and the hardness test motor 100 drives the hardness detection probe 101 to return to the initial position. Specifically, the hardness detector 1 of the present invention is the HV-1000 microhardness probe of Shandong Shancai Testing Instrument Co., Ltd.

[0033] like Figure 5 As shown, when the hardness test is completed, the lotus-type cylinder 4 drives the traction plate 3 to slide toward the transmission assembly line, and the tray 23 slides onto the tray bracket 26 along the pulley 28. The vertical cylinder 29 drives the tray bracket 26 to descend to the assembly line height, and the traction plate 3 is separated from the slot 32. At the same time, the top card of the blocking cylinder 7 descends, and the horizontal transmission drive motor 9 drives the tray 27 to continue moving on the upper layer of the horizontal conveying mechanism. When the tray 27 reaches the lifting mechanism, the tray 27 descends to the lower layer of the horizontal conveying mechanism through the hydraulic rod 10, completing the online detection and sorting process of the assembly line.

[0034] Traditional hardness testing is usually carried out after product production is completed, which not only requires huge manpower investment, but also makes it difficult to achieve 100% detection coverage, posing a challenge to the timeliness and accuracy of product quality control.

[0035] In order to solve this problem, we innovatively proposed a solution to integrate hardness testing directly into the production line. This production line realizes the automatic transmission and handling of components, effectively integrating the production and testing processes. Through the automated sorting system, unqualified products can be quickly identified and separated. In addition, the hardness test of the samples after production is completed directly on the production line, eliminating the need for manual handling and post-testing, significantly improving work efficiency and reducing labor costs; the horizontal conveying mechanism, with its unique design, realizes efficient horizontal transportation of the load-bearing mechanism of the parts to be tested. The mechanism has excellent transportation efficiency, and the tray 27 will not jam during the transmission process, and its subsequent repair and maintenance costs are relatively low.

[0036] The horizontal conveying mechanism is a highlight of our design. It adopts a double-layer structure design, with the upper layer used for detection and the lower layer used for sorting, which greatly improves the detection efficiency. This centralized structural layout not only optimizes space utilization, but also ensures efficient transmission of detection parts on the production line.

[0037] In the connection part between the pallet 27 and the inspection station, we carefully designed a caliper frame 501 integrated on the pallet 27. Through the clever cooperation of the vertical cylinder 29, the traction mechanism and the pallet 27, a stable and efficient pushing function of the pallet 27 is achieved. This design is not only simple in structure, but also highly integrated and stable, fully demonstrating our design innovation and practicality.

[0038] The design of the lifting mechanism also reflects our innovative concept. Through the coordinated work of the drive motor 18 and the cylinder 10, we have achieved the upper and lower conveying of the test pieces. Compared with the traditional chain transmission method, our design adopts the transmission method of cylinder and slide rail with gear, which not only makes the lifting of the sample table more stable, but also makes the structure more durable.

[0039] The hardness testing mechanism adopts the integrated technology of the hardness tester 1 and the testing lens, which not only improves the testing efficiency, but also ensures the real-time transmission of the testing results, thereby improving the sorting efficiency.
