Hub bolts need to be tested after production to check whether the strength and size of the hub bolts meet the standards to ensure that qualified hub bolts can be used normally in the future.

[0003] The existing inspection of wheel hub bolts is usually done manually, and the manual inspection method has low work efficiency, especially when multiple inspections are required for the wheel hub bolts, the inspection efficiency is even lower. Most of the existing inspection equipment also inspects the single performance of the wheel hub bolts, such as only inspecting the strength of the wheel hub bolts, and the inspection range is small. If other data need to be inspected, repeated inspections are required, which increases the workload and reduces work efficiency. Summary of the invention

DETAILED DESCRIPTION

[0025] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0026] like Figure 1 As shown, the utility model provides a wheel hub bolt detection device, including a base 1, a rotating circular plate 2 rotatably installed on the front end of the top of the base 1, the rotating circular plate 2 can rotate horizontally on the top of the base 1, and four hollow fixed cylinders 3 are vertically welded at the edge of the top surface of the rotating circular plate 2.

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, a support frame 4 is fixedly mounted at the top rear end of the base 1, and the base 1 has a built-in power component for driving the rotating circular plate 2 to rotate;

[0028] A positioning cylinder 10 for providing positioning for the hub bolts is locked and fixed in the fixing cylinder 3, and a discharging mechanism 9 is provided at the bottom of the left end of the fixing cylinder 3 for assisting the hub bolts to be discharged from the fixing cylinder 3 to the outside;

[0029] A shooting probe 5 and a stamping detection block 6 are respectively provided at the left and right ends of the inner top of the support frame 4;

[0030] The stamping detection block 6 is connected to the piston rod at the bottom of the cylinder 8. The cylinder 8 drives the stamping detection block 6 to move vertically downward to perform strength detection on the hub bolts. The cylinder 8 is locked and fixed on the top of the support frame 4.

[0031] A pressure sensor 15 is provided inside the positioning cylinder 10, and the pressure sensor 15 is connected to the bottom of the inner side of the fixing cylinder 3, and is used to detect the pressure applied by the wheel hub bolts;

[0032] In this embodiment, the power assembly includes a motor 11 installed in the base 1, a half gear 12 coaxially connected to the output shaft at the top of the motor 11, a full gear 13 meshing with the half gear 12, and a transmission shaft 14 vertically fixed to the inner ring of the full gear 13. The half gear 12 and the full gear 13 are respectively rotatably connected to the inner side of the base 1, and the transmission shaft 14 vertically passes through the inner top of the base 1 and is connected to the middle of the bottom end surface of the rotating circular plate 2.

[0033] In this embodiment, the four fixed cylinders 3 on the rotating circular plate 2 are equidistantly distributed in annular shapes, and the amplitude of the rotation of the full gear 13 driven by the half gear 12 when it rotates one circle corresponds to the distribution of the fixed cylinders 3. The fixed cylinder 3 rotates 90° around the center of the rotating circular plate 2 when the half gear 12 rotates one circle, so that the fixed cylinder 3 at the right end of the top of the rotating circular plate 2 is located directly below the pressure detection block 6, and the fixed cylinder 3 at the rear end of the top of the rotating circular plate 2 is located directly below the shooting probe 5, which is convenient for transmitting the two fixed cylinders 3 to the bottom of the stamping detection block 6 and the shooting probe 5 for detection at the same time, so as to realize multiple detections of the hub bolts and improve the detection efficiency;

[0034] Among them, a lighting lamp 7 is installed on the inner top of the support frame 4, and the lighting lamp 7 is located on the outer side of the shooting probe 5. After turning on the lighting lamp 7, it is convenient for the shooting probe 5 to more clearly shoot the upper hexagonal thread groove of the wheel hub bolt;

[0035] Two cylinders 8 are installed on the top of the support frame 4, and the bottom piston rod of another cylinder 8 away from the stamping detection block 6 is connected to the shooting probe 5, so that the shooting probe 5 can be driven by the cylinder 8 to move vertically, so that the shooting probe 5 can more clearly shoot the hexagonal thread groove on the wheel hub bolt;

[0036] The pressure sensor 15 and the positioning tube 10 are arranged concentrically, and a gap is arranged between the side surface of the pressure sensor 15 and the inner circle of the positioning tube 10, so that the pressure sensor 15 is squeezed when the positioning tube 10 is installed;

[0037] In this embodiment, the photographing probe 5 is connected to an external intelligent computer via a transmission cable, so that the image of the wheel hub bolt taken by the photographing probe 5 can be analyzed by the external intelligent computer;

[0038] In this embodiment, the motor 11, the electric push rod 91, the photo light 7 and the pressure sensor 15 are connected to an external control device, which is the prior art;

[0039] When inspecting the wheel hub bolt, a positioning cylinder 10 corresponding to the standard wheel hub bolt is installed in the fixing cylinder 3, and the wheel hub bolt to be inspected is vertically placed in the positioning cylinder 10. The wheel hub bolt moves downward in the positioning cylinder 10 and contacts the pressure sensor 15. The pressure sensor 15 detects the pressure applied by the wheel hub bolt. If the pressure sensor 15 detects the pressure and the top of the wheel hub bolt is higher than the top surface of the positioning cylinder 10, it means that the wheel hub bolt is longer than the standard length. If the wheel hub bolt is completely placed inside the positioning cylinder 10 and the pressure sensor 15 does not detect the pressure, it means that the wheel hub bolt is shorter than the standard length.

[0040] After the length detection of the hub bolt is completed, the half gear 12 is driven to rotate by starting the motor 11. The half gear 12 rotates one circle to drive the full gear 13 to rotate 90°. The full gear 13 cooperates with the transmission shaft 14 to drive the rotating circular plate 2 to rotate 90°. At this time, the fixed cylinder 3 moves to the bottom of the stamping detection block 6 along with the rotating circular plate 2. At this time, the cylinder connected to the stamping detection block 6 is controlled to drive the stamping detection block 6 to move downward to perform strength detection on the hub bolt;

[0041] After the strength test of the hub bolt is completed, the half gear 12 drives the full gear 13 to rotate 90 degrees, and the full gear 13 cooperates with the transmission shaft 14 to drive the rotating circular plate 2 to rotate 90 degrees. At this time, the hub bolt whose strength test is completed rotates to the bottom of the shooting probe 5 along with the rotating circular plate 2. The camera probe 5 can shoot the hexagonal thread groove on the top of the hub bolt, and can transmit the image of the hexagonal thread groove on the bolt head to the computer in real time for processing through the transmission cable connected to the shooting probe 5, and then use the special image processing software on the computer to measure and analyze the inner diameter of the hexagonal thread groove to determine whether the size of the hexagonal thread groove on the hub bolt is qualified. The size of the hexagonal thread groove affects the subsequent installation and removal of the hub bolt, so it needs to be tested. At the same time, the lighting lamp 7 can be started to assist the shooting probe 5 to shoot the hexagonal thread groove on the top of the hub bolt to improve the accuracy of shooting and detection.

[0042] like Figure 3 and Figure 4 As shown, in this embodiment, the discharging mechanism 9 includes an electric push rod 91 locked and fixed to the lower left end of the inner side of the base 1, a connecting plate 92 fixed on the piston rod at the top of the electric push rod 91, and a plurality of ejector pins 93 are installed at the top edge of the connecting plate 92, and the ejector pins 93 vertically penetrate the bottom end surface of the base 1;

[0043] In this embodiment, the base 1, the rotating circular plate 2, the fixed cylinder 3 and the positioning cylinder 10 are provided with holes corresponding to the ejector pin 93, and the holes on the fixed cylinder 3 and the positioning cylinder 10 at the left end of the top of the rotating circular plate 2 are aligned with the ejector pin 93. When the piston rod of the electric push rod 91 is in a fully retracted state, the ejector pin 93 is fully retracted into the base 1, so that the ejector pin 93 can move upward to eject the wheel hub bolt that has been inspected. At the same time, when the ejector pin 93 is in a retracted state, the rotating circular plate 2 can rotate horizontally on the top of the base 1.

[0044] Specifically, the wheel hub bolt that has been inspected rotates to the top left end of the base 1 along with the rotating circular plate 2. At this time, the electric push rod 91 is started to drive the connecting plate 92 to move upward, and the connecting plate 92 drives the ejector pin 93 to move upward through the through holes on the fixing tube 3 and the positioning tube 10 to eject the wheel hub bolt from the positioning tube 10 to the outside, and the wheel hub bolt is removed to complete the inspection of the wheel hub bolt.
