[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The following describes a hydraulic cylinder body seal detection device according to an embodiment of the utility model with reference to the accompanying drawings.

[0022] like Figure 1-Figure 4 As shown, the hydraulic cylinder body sealing detection device of the embodiment of the utility model may include: a conveying mechanism 1, an intercepting mechanism 2 and a detection mechanism 3.

[0023] The interception mechanism 2 is disposed on the conveying mechanism 1 , and the detection mechanism 3 may include two groups of lateral driving modules 31 , a pressurizing assembly 32 and a stopper 33 .

[0024] It should be noted that the conveying mechanism 1 described in this embodiment may include a stand, a drive motor, multiple rollers and a conveyor belt. The stand can be placed on the ground. The drive motor can drive a roller to rotate. Under the conveying action of the conveyor belt, multiple rollers rotate together.

[0025] The two groups of lateral drive modules 31 are respectively arranged on the conveying mechanism 1 , the pressurizing assembly 32 and the block 33 are respectively arranged on the sliders of the two groups of lateral drive modules 31 , and the pressurizing assembly 32 includes a first hydraulic telescopic rod 321 , a cylinder 322 and a pressure sensor 323 .

[0026] It should be noted that the specific structure of the lateral driving module 31 described in this embodiment has been disclosed in the prior art, so it will not be described in detail here.

[0027] The first hydraulic telescopic rod 321 is fixed on a slider of a transverse driving module 31 , the cylinder 322 is arranged at one end of the first hydraulic telescopic rod 321 , and the pressure sensor 323 is installed on the inner wall of the cylinder 322 .

[0028] In an embodiment of the present application, a controller may be installed on the interception mechanism 2, and the pressure sensor 323 is connected to the controller.

[0029] Specifically, the device can be arranged at the end of the hydraulic cylinder production line. When a large number of hydraulic cylinders are produced, they are transported by the conveying mechanism 1. First, a hydraulic cylinder to be inspected stops moving under the action of the interception mechanism 2. The hydraulic cylinder is perpendicular to the running direction of the conveying mechanism 1 (parallel to the plate 23). After the preset interception time (which can be obtained according to actual conditions), the interception mechanism 2 releases the restriction on the hydraulic cylinder.

[0030] The hydraulic cylinder moves with the conveying mechanism 1. When the hydraulic cylinder moves to the end of the transverse driving module 31, the transverse driving module 31 starts to run until the moving speed of the slider is increased to be equal to the running speed of the conveying mechanism 1, and the pressure component 32, the block 33 and the hydraulic cylinder are relatively still.

[0031] The pressurizing assembly 32 starts to run, and the first hydraulic telescopic rod 321 pushes the cylinder 322 toward the hydraulic cylinder to be tested, so that the end of the hydraulic cylinder is inserted into the cylinder 322. Under the action of the block 33, the first hydraulic telescopic rod 321 applies a rated pressure (for example: 200N) to the hydraulic cylinder. The pressure sensor 323 can measure this rated pressure and transmit the detection data to the controller. When the rated pressure is reached, the pressure maintaining state is entered.

[0032] If the rated pressure changes during the pressure-maintaining process, it means that the sealing of the hydraulic cylinder body is poor. There may be a risk of oil leakage during subsequent use. The controller determines that the hydraulic cylinder is a defective product and uses an external warning device (not shown in the figure) to remind workers to screen out the defective products.

[0033] If the rated pressure remains unchanged during the pressure maintaining process, it proves that the sealing of the hydraulic cylinder body is good, and the pressurizing component 32 and the lateral drive module 31 are reset. The hydraulic cylinder that has completed the inspection is collected into the storage box by an external manipulator, and the next hydraulic cylinder to be inspected repeats the above steps, thereby obtaining more sample data, simplifying the operation steps, and improving the inspection efficiency of the sealing of the hydraulic cylinder body.

[0034] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, an adjustment component 4 is disposed between the pressurizing component 32 and the stopper 33 and the corresponding lateral driving module 31 . The adjustment component 4 may include a first substrate 41 , a second substrate 42 and a plurality of adjustment knobs 43 .

[0035] The first substrate 41 is connected to the slider of the lateral driving module 31 , the second substrate 42 is connected to the pressurizing assembly 32 or the stopper 33 , and a plurality of adjusting knobs 43 are respectively mounted on the second substrate 42 , with one end of the adjusting knob 43 abutting against the first substrate 41 .

[0036] Specifically, when the specifications of the hydraulic cylinder to be tested change, that is, the axis of the hydraulic cylinder to be tested is not in the same straight line with the pressurizing assembly 32 and the block 33 during the testing process, the worker can rotate multiple adjustment knobs 43 to change the distance between the first substrate 41 and the second substrate 42, so that the axis of the hydraulic cylinder to be tested is in the same straight line with the pressurizing assembly 32 and the block 33, thereby ensuring the normal progress of the pressurizing step.

[0037] In one embodiment of the present invention, Figure 3 As shown, a laser sensor 51 is installed on the outer wall of the adjustment component 4.

[0038] It should be noted that the laser sensor 51 described in this embodiment is connected to the controller.

[0039] It is understandable that the laser sensor 51 can sense the position of the hydraulic cylinder. When the laser sensor 51 detects that the hydraulic cylinder moves to a preset position, the laser sensor 51 sends a signal to the controller, and the controller sends an operation signal to the lateral drive module 31 .

[0040] In one embodiment of the present invention, Figure 3 As shown, two guide plates 61 are installed at the bottom of the adjustment component 4 , and the two guide plates 61 are clamped on the conveying mechanism 1 .

[0041] Specifically, during the operation of the transverse driving module 31, the slider on the transverse driving module 31 drives the adjusting component 4 to move, and the adjusting component 4 drives the guide plate 61 to move along the edge of the conveying mechanism 1, thereby increasing the integrity between the pressurizing component 32, the adjusting component 4 and the transverse driving module 31, and avoiding damage to the device due to the reaction force applied by the hydraulic cylinder to the detection mechanism 3 during the detection process.

[0042] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, the interception mechanism 2 may include a bracket 21 , a second hydraulic telescopic rod 22 and a plate body 23 .

[0043] The bracket 21 is installed on the conveying mechanism 1 , the second hydraulic telescopic rod 22 is arranged on the bracket 21 , and the plate body 23 is installed on one end of the second hydraulic telescopic rod 22 .

[0044] Specifically, under the blocking effect of the plate body 23, the hydraulic cylinder to be tested is parallel to the plate body 23. After the lateral drive module 31 is reset, the controller sends an operation signal to the second hydraulic telescopic rod 22. The second hydraulic telescopic rod 22 pulls the plate body 23 upward, and the hydraulic cylinder to be tested passes through the bottom of the plate body 23.

[0045] In summary, the hydraulic cylinder body sealing detection device of the utility model can realize assembly-line detection of the hydraulic cylinder through the conveying mechanism and the lateral drive module, so as to obtain more sample data, and utilize the pressurizing component and the baffle to perform autonomous detection on the hydraulic cylinder to be detected, thereby simplifying the operation steps and improving the detection efficiency of the sealing of the hydraulic cylinder body.
