DETAILED DESCRIPTION

[0044] The hydraulic pipe buckle pressing forming quality detection device of the present application will be described in more detail below with reference to the accompanying drawings, in which preferred embodiments of the present application are shown, it should be understood that those skilled in the art can modify the present application described herein while still achieving the advantageous effects of the present application. Therefore, the following description should be understood as a broad knowledge for those skilled in the art, and not as a limitation of the present application.

[0045] The present application will be described in more detail in the following paragraphs with reference to the accompanying drawings. The advantages and features of the present application will be more apparent according to the following description. It should be noted that the drawings are very simplified and use non-precise proportions, only to facilitate and clarify the purpose of assisting the description of the embodiments of the present application.

[0046] In the prior art, after the hydraulic pipe is formed by buckling, the sleeve (i.e. the connection between the joint part and the rubber tube part) of the hydraulic pipe is prone to deformation due to the wear of the buckling device itself or external factors, resulting in a gap at the connection, thereby causing oil leakage. Therefore, the device detects the diameter of the end face of the sleeve to determine whether the outer diameter of the sleeve after buckling is consistent with the qualified outer diameter of the hydraulic pipe, thereby determining whether the hydraulic pipe is qualified or defective, as follows:

[0047] Embodiment one

[0048] As shown in Figures 1 to 3 Embodiments of the utility model propose a hydraulic pipe buckling forming quality detection device, comprising:

[0049] The stand 1 is used to provide support.

[0050] The lifting positioning plate 2 is slidingly installed 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 positioning plate 2 to drive the components to rotate around the axial direction of the hydraulic pipe, so as to perform multi-angle detection on the sleeve of the hydraulic pipe.

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

[0053] The clamping assembly 5 is fixedly connected with the detection assembly 4 and forms an X-shaped structure, and is used to clamp or release the hydraulic pipe after buckling forming, i.e. the hydraulic pipe is stabilized at a specific position by the clamping assembly 5, so that the detection assembly 4 can obtain parameters.

[0054] It should be particularly noted that the detection part of the detection assembly 4 can be better aligned with the hydraulic pipe by connecting the clamping assembly 5 and the detection assembly 4 in an X-shaped manner, so that interference occurs between them during operation (such as interference between the clamping assembly 5 and the detection assembly 4 during clamping).

[0055] The clamping center point of the clamping assembly 5 and the rotating axis of the rotating module 3 are located in the same vertical plane, which ensures that the rotating module 3 drives the detection assembly 4 to rotate for multi-angle detection without interference with the hydraulic pipe, thereby ensuring the reliability of the overall operation process.

[0056] The control unit is connected with the lifting positioning plate 2, the rotating module 3, the detection assembly 4 and the clamping assembly 5, controls the coordinated operation of the components, and completes the detection.

[0057] The device sets the detection assembly 4, the rotating module 3, the lifting positioning plate 2, the clamping assembly 5 and the control unit, controls the clamping assembly 5 to complete the clamping positioning operation of the hydraulic pipe to be detected through the control unit, cooperates with the rotating module 3 and the lifting positioning plate 2, so that the detection assembly 4 can measure the outer diameters of the upper and lower end faces of the hydraulic pipe sleeve at multiple angles, obtains multiple sets of outer diameter data parameters, and judges whether the hydraulic pipe is qualified for pressing according to the measured multiple sets of outer diameter data parameters, so as to conveniently and efficiently complete the detection of the hydraulic pipe after pressing, and realize the function of effectively monitoring the production quality of the hydraulic pipe while ensuring the production rate of the hydraulic pipe.

[0058] In the embodiment, the detection assembly 4 comprises a mounting plate 41 and a laser detection sensor 42.

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

[0060] In addition, the laser detection sensor 42 is provided with two laser detection sensors 42, and the two laser detection sensors 42 are arranged in a staggered manner at the outer side of the end of the mounting plate 41, so as to increase the detection range of the hydraulic pipe and improve the detection effect.

[0061] It should be particularly pointed out that the laser detection sensor 42 is used for detection, which can realize non-contact detection of the hydraulic pipe, accurately know the distance between the hydraulic pipe and the sleeve, obtain the outer diameter information of the sleeve through the distance information, and judge whether the sleeve is deformed or not, so as to complete the detection of the hydraulic pipe.

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

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

[0064] The synchronous cylinder 51 is fixedly connected with the mounting plate 41, and the length direction of the synchronous cylinder 51 forms an angle with the length direction of the mounting plate 41, and the two clamping jaws 52 move synchronously along the length direction of the synchronous cylinder 51, and the moving directions are opposite, so that the clamping jaw 52 does not contact the laser detection sensor 42 when moving, and the stability of the device is ensured.

[0065] In one example, the angle is set to 90°, so that the clamping jaw 52 is arranged vertically with the laser detection sensor 42, and the detection effect is improved.

[0066] In a further embodiment, the lifting positioning plate 2 and the upright frame 1 are connected by a lifting module 21 to complete the lifting function. The lifting module 21 can be configured as a screw drive 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 face of the hydraulic pipe sleeve 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] Example 2

[0069] like Figure 4 As shown, this embodiment, based on Embodiment 1, also proposes a detection method for a hydraulic pipe crimping quality detection device, including the hydraulic pipe crimping quality detection device described in Embodiment 1, specifically including the following steps:

[0070] S1. The control unit controls the clamping assembly 5 to clamp the hydraulic tube to be tested, and exposes one end face of the sleeve of the hydraulic tube to be tested.

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

[0072] S3. While the control unit controls the clamping assembly 5 to separate from the hydraulic pipe to be tested, it drives the rotating module 3 to rotate, adjusting the relative position of the detection 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 component 5 to clamp the hydraulic pipe to be tested again, and the detection component 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 sends a lifting command to the lifting positioning plate 2.

[0075] S6. When the lifting and positioning plate 2 drives the clamping component 5 and the detection component 4 to rise and fall to the preset height, the control unit re-controls the clamping component 5 to clamp the hydraulic pipe to be tested, and exposes the other end face of the sleeve of the hydraulic pipe to be tested.

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

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

[0078] In further embodiments, the control unit is further configured to receive and integrate the plurality of outer diameter parameters of the exposed end surface of the hydraulic pipe sleeve acquired by the detection assembly 4, and compare with a preset parameter range.

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

[0080] When the control unit detects that the plurality of outer diameter parameters are inconsistent with the preset parameter range, the control unit controls the unit control clamping assembly 5 to always maintain a clamped state and sends an alarm.

[0081] When the control unit detects that the plurality of outer diameter parameters are consistent with the preset parameter range, the control unit controls the unit control clamping assembly 5 to separate from the detected hydraulic pipe, and 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 conventional statistical methods in the prior art, and therefore will not be described here.

[0083] By comparing the measured outer diameter parameter information with the preset parameter range, the judgment of whether the hydraulic pipe is qualified can be completed, and therefore compared with the hydraulic oil detection method in the prior art, the present method can achieve the purpose of convenient and efficient detection, and can 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 modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
