When two hollow semi-conical cones are combined together, a truncated cone structure with a hollow part is formed, and the hollow part is for the passage of steel bars.

[0037] refer to Figure 2 and Figure 3 This embodiment proposes an intelligent anchor plate hardness testing device, including a feeding part 2, a testing part 3 and a recovery part (not shown in the figure). The testing part 3 includes a hardness tester and a workpiece moving device.

The loading guide rod 203 is fixed to the base plate 202, and one end of the loading guide rod 203 is connected to the output end of the vibration disk 201; the loading guide rod 204 is slidably connected to the base plate 202, and the sliding direction is perpendicular to the length direction of the base plate 202, that is, the Y direction, and the action end of the second pushing unit 206 is fixed to the loading guide rod 204; when the second pushing unit 206 is in a retracted state, one end of the loading guide rod 204 is connected to the other end of the loading guide rod 203; when the second pushing unit 206 is in an extended state, one end of the loading guide rod 204 is connected to the action end of the first pushing unit 205, and the other end of the loading guide rod 204 is connected to one end of the detection guide rod 3022; the first pushing unit 205 is used to push the anchor plate 1 on the loading guide rod 204 to the detection guide rod 3022.

[0039] The unloading unit includes a first slide 3029 and a second slide 30210. The first slide 3029 includes a material drop hole 30211 opened on the bottom surface and a valve 30212 for opening and closing the material drop hole 30211. The second slide 30210 is located below the first slide 3029. The recovery part includes a recovery tank 1 and a recovery tank 2. One end of the first slide 3029 is connected to the other end of the guide rod 3022 for detection, and the other end of the first slide 3029 is used to output the qualified anchor sheet 1 to the recovery tank 1; one end of the second slide 30210 is connected to the material drop hole 30211, and the other end of the second slide 30210 is used to output the unqualified anchor sheet 1 to the recovery tank 2.

[0040] The hardness testing process of the equipment is as follows:

[0041] S1. The vibration plate 201 outputs the anchor sheet to the feeding guide rod 203. After the anchor sheet at the front end of the feeding guide rod 203 is pushed into the feeding guide rod 204 by the rear end anchor sheet, the vibration plate 201 stops, such as Figure 7 As shown;

[0042] S2. The second push unit 206 is extended to push out the second feeding guide rod 204, so that both ends of the second feeding guide rod 204 are connected to the action end of the first push unit 205 and one end of the detection guide rod 3022, respectively. Figure 8 As shown;

[0043] S3. The first push unit 205 is extended to push the anchor sheet on the feeding guide rod 204 to the detection guide rod 3022, after which the first push unit 205 and the second push unit 206 are retracted, the vibration plate 201 is started, and the next anchor sheet is output;

[0044] S4. Figure 8 As shown, the toggle unit pushes the anchor sheet inputted to the detection guide rod 3022 to the bottom of the detection needle 3013, and the detection needle 3013 descends to detect the hardness of the anchor sheet. The background records the hardness value of the anchor sheet and compares it with the standard value to determine whether the hardness of the anchor sheet is qualified.

[0045] S5. The toggle unit pushes the detected anchor sheet into the unloading unit, and then the toggle unit is reset to move the next anchor sheet;

[0046] S6. If the inspection result of the anchor sheet entering the unloading unit is qualified, the blanking hole 30211 is in a closed state, and the anchor sheet is output along the first slide 3029; if the inspection result of the anchor sheet entering the unloading unit is unqualified, the blanking hole 30211 is in an open state, and the anchor sheet enters the second slide 30210 through the first slide 3029 and the blanking hole 30211, and is output along the second slide 30210.

[0047] After the anchor plate enters the unloading unit, it needs to rely on gravity to slide down the slide. In order to improve the smoothness of its sliding, the present application installs a vibrator at the bottom of the first slide 3029 and the second slide 30210 to promote the sliding of the anchor plate through vibration.

[0048] like Figure 5As shown, in this embodiment, the toggle unit includes a screw rod 3023 arranged axially along the detection guide rod 3022, a driving unit 3024 for driving the screw rod 3023, a nut block 3025 threadedly connected to the screw rod 3023, a track 3028 slidably connected to the nut block 3025, and a telescopic unit 3026 fixed to the nut block 3025, wherein the action end of the telescopic unit 3026 is provided with a paddle 3027, and the telescopic unit 3026 is used to control the paddle 3027 to approach or move away from the detection guide rod 3022. The driving unit 3024 realizes the rotation of the screw rod 3023, and the nut block 3025 can only translate along the screw rod 3023 due to the limitation of the track 3028, thereby realizing the movement of the paddle 3027 along the detection guide rod 3022.

[0049] In order to prevent the anchor plate 1 from being displaced during detection and affecting the detection results, in this embodiment, the detection guide rod 3022 is a magnetic rod (the anchor plate 1 is generally an iron product) for adsorbing the anchor plate 1. Of course, the adsorption force cannot be too strong so that the pick 3027 cannot push the anchor plate 1.

[0050] In order to facilitate the self-adjustment of the detection device, a second lifting unit 30213 is provided below the base 3021 of this embodiment to adjust the Z-direction height of the workpiece moving device. Figure 7 As shown, the first lifting unit 3012 is slidably connected to the frame 3011, and the sliding direction is perpendicular to the sliding direction of the anchor plate 1 on the guide rod 3022 for detection. The frame 3011 is installed with a third pushing unit 3014, and the third pushing unit 3014 is used to push the first lifting unit 3012 to slide on the frame 3011 to achieve Y-axis adjustment of the detection needle 3013.

[0051] The magnetic detection guide rod 3022 can realize automatic loading, conveying and unloading of the anchor sheet 1 on the one hand, and on the other hand, when the anchor sheet 1 is detected, the detection guide rod 3022 can fill the hollow part of the anchor sheet 1, thereby avoiding deformation of the anchor sheet 1 during detection.

[0052] In this embodiment, the first pushing unit 205, the second pushing unit 206, the third pushing unit 3014, and the telescopic unit 3026 all use cylinders, the first lifting unit 3012 and the second lifting unit 30213 use lifting electric cylinders or hydraulic cylinders, and the driving unit 3024 uses a servo motor.

[0053] In addition, a protective cover is set around the detection part to prevent the anchor sheet from breaking and splashing during the detection process to injure people.

[0054] The above embodiments are only used to explain the concept of the present invention, rather than to limit the protection of the present invention. Any non-substantial changes to the present invention using this concept shall fall within the protection scope of the present invention.
