[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.
[0025] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present application provides a vehicle brake fork strength detection device, the device includes a base 101 arranged on a frame, the base 101 is provided with a profiling protrusion structure 1011, a support 102 is provided on one side of the support seat 104, a lateral driving cylinder 103 is provided on the support 102, and the lateral driving cylinder 103 is connected to the support seat 104, a lower pressing block 108 is arranged above the base 101, the lower pressing block 108 is connected to the driving cylinder 109, the lower pressing block 108 is provided with a test protrusion 117, and a limiting structure 116 is also provided on the lower pressing block 108, and the limiting structure 116 is provided with a profiling groove 11 61, also includes a pressing mechanism 106 with a displacement sensor and an lifting mechanism 107 with a displacement sensor, the pressing mechanism 106 is connected to a first pressure sensor 110, the first pressure sensor 110 is connected to a pressing head 111, the pressing head 111 is provided with a pressing column 112, the lifting mechanism 107 is connected to a second pressure sensor 113, the second pressure sensor 113 is connected to an upper head 114, the upper head 114 is provided with an upper column 115, the pressing column 112 is used to press down the tail end of the fork 300 located on the base 101, and the upper head 114 is used to lift the tail end of the fork 300 located on the base 101.
[0026] Specifically, the horizontal line driving cylinder 109 first drives the support seat 104 to extend, and then places the fork 300 on the base 101, so that the groove of the fork 300 cooperates with the profiling protrusion structure 1011, and the tail end of the fork 300 is supported by the support seat 104. Next, the driving cylinder 109 drives the pressing block 108 to descend, so that the test protrusion 117 is inserted between the two fork arms 310 of the fork 300, and the profiling groove 1161 of the limiting structure 116 cooperates with the main body of the fork 300. The limiting structure 116 is used to limit the rotating fork 300 when a force is applied to the tail end of the fork 300, so as to prevent the fork 300 from accidentally flying out of the base 101 due to excessive force. Then, the driving cylinder 109 drives the support seat 104 to retract. The lower pressing column 112 is driven by the lower pressing mechanism 106 to press the tail end of the fork 300 downward, which can cause the fork 300 to rotate. The test protrusion 117 will apply pressure to one of the fork arms 310. The first pressure sensor 110 is used to detect the pressure value applied by the lower pressing column 112. When the pressure value reaches the preset value, the displacement sensor of the lower pressing mechanism 106 obtains the corresponding displacement value, and judges whether the strength of the fork arm 310 meets the requirements based on the value. Similarly, the upper pushing column 115 is driven by the upper pushing mechanism 107 to push the tail end of the fork 300 upward, which can cause the fork 300 to rotate. The test protrusion 117 will apply pressure to the other fork arm 310. The second pressure sensor 113 is used to detect the pressure value applied by the upper pushing column 115. When the pressure value reaches the preset value, the displacement sensor of the upper pushing mechanism 107 obtains the corresponding displacement value, and judges whether the strength of the fork arm 310 meets the requirements based on the value.
[0027] In one embodiment, the pressing mechanism 106 with a displacement sensor is a servo electric cylinder with a displacement sensor. Specifically, an existing servo electric cylinder with a displacement sensor can be used here.
[0028] In one embodiment, the lifting mechanism 107 with a displacement sensor is a servo electric cylinder with a displacement sensor. Specifically, an existing servo electric cylinder with a displacement sensor can be used here.
[0029] In one embodiment, the bracket 102 is provided with a guide groove 105, and the support seat 104 is slidably matched with the guide groove 105. This arrangement facilitates the movement of the support seat 104 to be smoother.
[0030] In one embodiment, if Figure 3 As shown, the lower pressing block 108 is connected to a guide assembly 118 arranged on the frame. The guide assembly 118 can be composed of a guide column and a linear bearing. This arrangement can make the movement of the lower pressing block 108 smoother. Among them, the guide column is arranged on the frame, and the linear bearing is arranged on the lower pressing block 108.
[0031] In one embodiment, the number of the limiting structures 116 is two, and the two limiting structures 116 are arranged at intervals.
[0032] In one embodiment, if Figure 3 As shown, two limit posts 119 are provided on the frame, and the limit posts 119 are located below the lower pressing block 108. Specifically, the two limit posts 119 are respectively located on both sides of the base 101. The limit posts 119 are used to limit the descending position of the lower pressing block 108.
