Description

Technical Field

[0001] The invention relates to the field of hydraulic pipe detection, and in particular to a hydraulic pipe crimping forming quality detection device and a detection method. Background Art

[0002] At present, the production volume of hydraulic pipes in the market is very large, and they are mostly used in engineering machinery, precision equipment manufacturing, etc. When assembling hydraulic pipes, it is necessary to crimp the sleeve, joint and hose. Good crimping size and accuracy can effectively ensure that the hydraulic pipe will not leak oil under the use pressure. Therefore, the inspection of hydraulic pipes after crimping is an important process link.

[0003] In the prior art, it is difficult to directly observe and judge whether there is a hidden danger of oil leakage in the hydraulic pipe after crimping. In most production processes, due to cost, efficiency and other factors, oil leakage detection is often not performed on every product after crimping. For example, when the production capacity demand is large, if all products are tested for oil leakage, each hydraulic pipe needs to be connected to the hydraulic circuit for testing. Because of the complexity of the hydraulic system installation itself, it will take a long time and affect the production capacity. In addition, due to the adhesion characteristics of the hydraulic oil, it is difficult to completely clean the hydraulic pipe after the test.

[0004] Therefore, a hydraulic pipe crimping forming quality detection device and detection method are needed to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a hydraulic pipe crimping quality detection device and detection method, so as to conveniently and efficiently complete the detection of the hydraulic pipe after crimping, thereby ensuring the production rate of the hydraulic pipe while also being able to effectively monitor the production quality of the hydraulic pipe.

[0006] In order to solve the above technical problems, the present invention provides a hydraulic pipe crimping quality detection device, comprising:

[0007] A stand for providing support;

[0008] A lifting and positioning plate is slidably mounted on one side of the stand;

[0009] A rotating module is arranged on the lifting and positioning plate;

[0010] A detection component, which is arranged on the lower surface of the lifting and positioning plate and connected to the output end of the rotating module, and is used to obtain the outer diameter parameters of the upper and lower end surfaces of multiple groups of hydraulic pipe sleeves in a non-contact manner;

[0011] A clamping assembly, fixedly connected to the detection assembly to form an X-shaped structure, used for clamping or releasing the hydraulic pipe after being pressed and formed;

[0012] Wherein, the clamping center point of the clamping assembly and the rotation axis of the rotating module are located in the same vertical plane;

[0013] A control unit is connected to the lifting and positioning plate, the rotating module, the detection component and the clamping component.

[0014] Further, the detection assembly includes a mounting plate and a laser detection sensor;

[0015] The laser detection sensor is arranged at the end of the mounting plate.

[0016] Furthermore, two laser detection sensors are provided, and the two laser detection sensors are staggeredly arranged on the outer side of the end of the mounting plate.

[0017] Furthermore, the laser detection sensor obtains parameter information of the outer diameters of the upper and lower end surfaces of multiple groups of hydraulic pipe sleeves through the lifting and lowering of the lifting and positioning plate and the rotation of the rotating module.

[0018] Further, the clamping assembly includes a synchronous cylinder and two clamping claws connected to the synchronous cylinder;

[0019] The synchronous cylinder is fixedly connected to the mounting plate, and a length direction forms an angle with a length direction of the mounting plate;

[0020] The two clamping jaws move synchronously along the length direction of the synchronous cylinder, and the moving directions are opposite.

[0021] Furthermore, the angle is set to 90°.

[0022] Furthermore, the lifting positioning plate and the stand are connected via a lifting module.

[0023] Furthermore, the control unit is also used to receive and integrate multiple groups of outer diameter parameters of the exposed end faces of the hydraulic pipe sleeves to be tested acquired by the detection component, and compare them with a preset parameter range.

[0024] On the other hand, the present invention also proposes a method for detecting a hydraulic pipe crimping quality detection device, including the hydraulic pipe crimping quality detection device described in the above embodiment, specifically comprising the following steps:

[0025] S1, the control unit controls the clamping assembly to clamp the hydraulic pipe to be tested, and exposes one end surface of the sleeve of the hydraulic pipe to be tested;

[0026] S2. The detection component completes the acquisition of the outer diameter parameters of the exposed end surface of the hydraulic pipe sleeve to be detected under the instruction of the control unit;

[0027] S3, the control unit controls the clamping assembly to separate from the hydraulic pipe to be tested, and drives the rotating module to rotate, so as to adjust the relative position of the testing assembly and the sleeve of the hydraulic pipe to be tested;

[0028] S4. When the rotating module rotates to a preset angle, the control unit controls the clamping assembly to clamp the hydraulic pipe to be tested again, and the testing assembly obtains the outer diameter parameter of the exposed end face of the sleeve of the hydraulic pipe to be tested at the current position under the instruction of the control unit;

[0029] S5, the control unit controls the clamping assembly to separate from the hydraulic pipe to be tested, and at the same time issues a lifting command to the lifting positioning plate;

[0030] S6. When the lifting and positioning plate drives the clamping assembly and the detection assembly to rise and fall to a preset height, the control unit controls the clamping assembly to clamp the hydraulic pipe to be detected again, and exposes the other end surface of the sleeve of the hydraulic pipe to be detected;

[0031] S7. Repeat the above steps S2 to S4 to complete the detection.

[0032] Furthermore, the control unit is also used to receive and integrate multiple groups of outer diameter parameters of the exposed end faces of the hydraulic pipe sleeves to be tested acquired by the detection component, and compare them with the preset parameter range;

[0033] The detection method of the hydraulic pipe crimping quality detection device further comprises the following steps:

[0034] When the control unit detects that the multiple sets of outer diameter parameters are inconsistent with the preset parameter range, the control unit controls the clamping assembly to always maintain the clamping state and issues an alarm;

[0035] When the control unit detects that the multiple groups of outer diameter parameters are consistent with the preset parameter range, the unit controls the clamping assembly to separate from the detected hydraulic pipe, so that the detected hydraulic pipe is transported to the next process.

[0036] Compared with the prior art, the present invention has at least the following beneficial effects:

[0037] By setting up a detection component, a rotating module, a lifting and positioning plate, a clamping component and a control unit, the control unit controls the clamping component to complete the clamping and positioning operation of the hydraulic pipe to be detected, and cooperates with the rotating module and the lifting and positioning plate to enable the detection component to measure the upper and lower end surface outer diameters of the hydraulic pipe sleeve at multiple angles to obtain multiple groups of outer diameter data parameters. According to the measured multiple groups of outer diameter data parameters, it is possible to judge whether the hydraulic pipe is qualified for buckling, so as to achieve the purpose of conveniently and efficiently completing the detection of the hydraulic pipe after buckling, and realizing the function of effectively monitoring the production quality of the hydraulic pipe while ensuring the production rate of the hydraulic pipe.

[0038] Furthermore, by locating the clamping center point of the clamping assembly and the rotation axis of the rotating module in the same vertical plane, the detection assembly can rotate around the axis of the hydraulic pipe to be detected, ensuring that there is no interference with the hydraulic pipe during rotation, thereby ensuring the stability of the device operation.

[0044] The hydraulic pipe crimping quality inspection device and inspection method of the present invention will be described in more detail below in conjunction with a schematic diagram, wherein a preferred embodiment of the present invention is shown, and it should be understood that those skilled in the art can modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation of the present invention.

[0045] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and are not in exact proportions, and are only used to facilitate and clearly assist in illustrating the purpose of the embodiments of the present invention.

[0046] In the prior art, after the hydraulic pipe is crimped and formed, the sleeve of the hydraulic pipe (i.e., the connection between the joint and the hose) is easily deformed due to the wear of the crimping device itself or external factors, resulting in a gap at the connection, thereby causing oil leakage. Therefore, this device detects the diameter of the sleeve end face to determine whether the hydraulic pipe is qualified or defective according to whether the outer diameter of the sleeve after crimping is consistent with the outer diameter of the qualified hydraulic pipe, as shown below:

[0047] Embodiment 1

[0048] like Figures 1 to 3 As shown, the embodiment of the present invention provides a hydraulic pipe crimping forming quality detection device, comprising:

[0049] The stand 1 is used for providing support.

[0050] The lifting and positioning plate 2 is slidably mounted on one side of the stand 1 to drive the components to move in the height direction.

[0051] The rotating module 3 is arranged on the lifting and positioning plate 2 to drive the components to rotate around the axis direction of the hydraulic pipe so as to perform multi-angle detection on the sleeve of the hydraulic pipe.

[0052] The detection component 4 is arranged on the lower surface of the lifting and positioning plate 2 and connected to the output end of the rotating module 3, and is used to obtain the outer diameter parameters of the upper and lower end surfaces of multiple groups of hydraulic pipe sleeves in a non-contact manner.

[0053] The clamping assembly 5 is fixedly connected to the detection assembly 4 to form an X-shaped structure, and is used to clamp or loosen the hydraulic pipe after being pressed and formed. That is, the hydraulic pipe is fixed in a specific position by the clamping assembly 5, so that the detection assembly 4 can obtain parameters easily.

[0054] It should be particularly noted that by connecting the clamping assembly 5 and the detection assembly 4 in an X shape, the detection portion of the detection assembly 4 can be better aligned with the hydraulic pipe, so that interference occurs between the two during operation (such as the clamping assembly 5 interfering with the detection assembly 4 during the clamping process, etc.).

[0055] Among them, the clamping center point of the clamping component 5 and the rotation axis of the rotating module 3 are located in the same vertical plane, ensuring that the rotating module 3 will not interfere with the hydraulic pipe when driving the detection component 4 to rotate for multi-angle detection, thereby ensuring the reliability of the overall operation process.

[0056] The control unit is connected with the lifting and positioning plate 2, the rotating module 3, the detection component 4 and the clamping component 5 to control the multiple components to work in coordination and complete the detection.

[0057] The device is provided with a detection component 4, a rotating module 3, a lifting and positioning plate 2, a clamping component 5 and a control unit. The control unit controls the clamping component 5 to complete the clamping and positioning operation of the hydraulic pipe to be detected, and cooperates with the rotating module 3 and the lifting and positioning plate 2 so that the detection component 4 can measure the upper and lower end surface outer diameters of the hydraulic pipe sleeve at multiple angles to obtain multiple groups of outer diameter data parameters. According to the measured multiple groups of outer diameter data parameters, it can be judged whether the hydraulic pipe is qualified for buckling, so as to achieve the purpose of conveniently and efficiently completing the detection of the hydraulic pipe after buckling, and realizing the function of effectively monitoring the production quality of the hydraulic pipe while ensuring the production rate of the hydraulic pipe.

[0058] In this embodiment, the detection component 4 includes a mounting plate 41 and a laser detection sensor 42 .

[0059] The laser detection sensor 42 is arranged at the end of the mounting plate 41 .

[0060] Furthermore, two laser detection sensors 42 are provided, and the two laser detection sensors 42 are staggeredly arranged on the outer side of the end of the mounting plate 41 to increase the detection range of the hydraulic pipe and improve the detection effect.

[0061] It should be particularly noted that by using the laser detection sensor 42 for detection, it is possible to achieve non-contact detection of the hydraulic pipe and accurately know the distance between it and the sleeve. The outer diameter information of the sleeve can be obtained through the distance information, and then it can be determined whether the sleeve is deformed, etc., to complete the detection of the hydraulic pipe.

[0062] The laser detection sensor 42 obtains parameter information of the outer diameters of the upper and lower end surfaces of multiple groups of hydraulic pipe sleeves through the lifting and lowering of the lifting and positioning plate 2 and the rotation of the rotating module 3.

[0063] In other embodiments, the clamping assembly 5 is further defined. Specifically, the clamping assembly 5 includes a synchronous cylinder 51 and two clamping jaws 52 connected to the synchronous cylinder 51 .

[0064] Among them, the synchronous cylinder 51 is fixedly connected to the mounting plate 41, and the length direction forms an angle with the length direction of the mounting plate 41, and the two clamps 52 move synchronously along the length direction of the synchronous cylinder 51, and the moving directions are opposite, so that the clamps 52 will not contact the laser detection sensor 42 when moving, ensuring the stability of the device operation.

[0065] In one example, the angle is set to 90°, so that the clamp 52 and the laser detection sensor 42 are vertically arranged to improve the detection effect.

[0066] In a further embodiment, the lifting and positioning plate 2 is connected to the stand 1 via a lifting module 21 to complete the lifting function. The lifting module 21 can be set as a screw transmission mechanism.

[0067] In addition, it should be noted that the control unit is also used to receive and integrate multiple sets of outer diameter parameters of the exposed end faces of the hydraulic pipe sleeves to be tested obtained by the detection component 4, and compare them with the preset parameter range to complete the judgment of whether the hydraulic pipe is qualified.

[0068] Embodiment 2

[0069] like Figure 4 As shown, this embodiment further proposes a detection method of a hydraulic pipe crimping forming quality detection device based on the first embodiment, including the hydraulic pipe crimping forming quality detection device described in the first embodiment, and specifically includes the following steps:

[0070] S1, the control unit controls the clamping assembly 5 to clamp the hydraulic pipe to be tested, and exposes one end surface of the sleeve of the hydraulic pipe to be tested;

[0071] S2, the detection component 4 completes the acquisition of the outer diameter parameters of the exposed end surface of the hydraulic pipe sleeve to be detected under the instruction of the control unit;

[0072] S3, the control unit controls the clamping assembly 5 to separate from the hydraulic pipe to be tested, and drives the rotating module 3 to rotate, so as to adjust the relative position of the testing assembly 4 and the sleeve of the hydraulic pipe to be tested;

[0073] S4, when the rotating module 3 rotates to the preset angle, the control unit controls the clamping assembly 5 to clamp the hydraulic pipe to be tested again, and the detection assembly 4 obtains the outer diameter parameter of the exposed end face of the sleeve of the hydraulic pipe to be tested at the current position under the instruction of the control unit;

[0074] S5, the control unit controls the clamping assembly 5 to separate from the hydraulic pipe to be tested, and at the same time issues a lifting command to the lifting positioning plate 2;

[0075] S6, when the lifting and positioning plate 2 drives the clamping assembly 5 and the detection assembly 4 to rise and fall to the preset height, the control unit controls the clamping assembly 5 to clamp the hydraulic pipe to be detected again, and exposes the other end surface of the sleeve of the hydraulic pipe to be detected;

[0076] S7. Repeat the above steps S2 to S4 to complete the detection.

[0077] Through the above steps, the outer diameter parameters of the different end faces and different circumferential positions of the hydraulic pipe sleeve to be tested can be cyclically and comprehensively tested, ensuring that the acquired test data can accurately reflect the outer diameter characteristics of the hydraulic pipe sleeve to be tested, and provide sufficient and reliable data support for subsequent analysis, judgment and other related work based on the test results.

[0078] In a further embodiment, the control unit is further used to receive and integrate multiple groups of outer diameter parameters of the exposed end faces of the hydraulic pipe sleeves to be inspected acquired by the inspection component 4, and compare them with a preset parameter range.

[0079] The detection method of the hydraulic pipe crimping quality detection device further comprises the following steps:

[0080] When the control unit detects that the multiple sets of outer diameter parameters are inconsistent with the preset parameter range, the unit controls the clamping assembly 5 to always maintain the clamping state and alarms;

[0081] When the control unit detects that the multiple groups of outer diameter parameters are consistent with the preset parameter range, the unit control clamping assembly 5 is controlled to separate from the detected hydraulic pipe, so that the detected hydraulic pipe is transported to the next process.

[0082] It should be noted that the preset parameter range is composed of data measured by qualified hydraulic pipes, which is obtained by statistics in a conventional manner in the prior art, so it will not be elaborated here.

[0083] By comparing the measured outer diameter parameter information with the preset parameter range, it is possible to determine whether the hydraulic pipe is qualified. Therefore, compared with the hydraulic oil detection method used in the prior art, this method can achieve the purpose of convenient and efficient detection, and realize the function of effectively monitoring the production quality of the hydraulic pipe while ensuring the production rate of the hydraulic pipe.

[0084] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
