[0002] In the modern industrial field, especially in the engineering machinery and precision equipment manufacturing industry, the application of hydraulic pipe is extremely wide. With the continuous expansion of the production scale of hydraulic pipe, its quality control is increasingly critical.

[0003] The hydraulic pipe is mainly composed of rubber and steel wire braided rubber pipe, and in its production process, the sleeve, joint and rubber pipe need to be buckled. The size accuracy after buckling has a decisive influence on the performance of the hydraulic pipe, and good buckling size and accuracy are the key elements to ensure that the hydraulic pipe does not leak oil when subjected to use pressure, so the buckling size of the hydraulic pipe becomes an extremely important quality parameter.

[0004] Usually, the rubber pipe of the hydraulic pipe has a natural bending direction, and in the assembly link, the rubber pipe needs to be precisely connected and assembled with the sleeve and the joint. However, when the hydraulic pipe is detected, many positioning problems are faced. On the one hand, the relative position of the rubber pipe part and the sleeve needs to be accurately determined; on the other hand, after the joint is inserted into the rubber pipe, due to the action of gap and stress and other factors, uncertain deflection will be generated, and if buckling is directly performed at this time, the joint needs to be bent for matching application in subsequent application, so that the rubber pipe will be subjected to the torsional force caused by its own bending direction during application, affecting the overall application performance.

[0005] Therefore, a hydraulic pipe joint detection righting device is needed to solve the above problems. UTILITY MODEL CONTENTS

[0017] Further, the detection sensor is further provided for detecting whether the joint part of the hydraulic pipe is connected to the rubber pipe part.

Therefore, the following description should be understood as extensive knowledge for those skilled in the art, and not as a limitation on the utility model.

[0033] The utility model will be described in more detail below in conjunction with the schematic diagram. According to the following description, the advantages and features of the utility model will be more apparent. It should be noted that the drawings are all in a very simplified form and all use non-precise proportions, only for the purpose of facilitating, clearly assisting in the description of the utility model embodiments.

[0034] As Figures 1 to 4 shown, the utility model embodiment proposes a kind of hydraulic pipe joint detection righting device, including support 1, drive mechanism 2 and clamping assembly 3.

[0035] The drive mechanism 2 is fixedly installed on the support 1, and output end is connected the clamping assembly 3, for driving clamping assembly 3 to operate.

[0036] Wherein, the clamping assembly 3 includes two position clamping jaw 31 and righting insert piece 32.

[0037] Specifically, two the position clamping jaw 31 moves in opposite directions under the power of drive mechanism 2, to clamp the sleeve of hydraulic pipe connection.

[0038] And, the righting insert piece 32 is fixedly installed on the inner side wall of two the position clamping jaw 31, moves synchronously with the position clamping jaw 31, to clamp the hydraulic pipe joint part inserted into sleeve.

[0039] That is, the device is positioned by setting position clamping jaw 31 and righting insert piece 32 to clamp the sleeve of hydraulic pipe connection and joint part respectively, so that joint part, sleeve and rubber tube part are always in a given posture when buckling, to avoid the relative deflection misplacement of joint part and rubber tube part under external force or self influence, so that the hydraulic pipe buckled in this misplacement state is matched and connected, and the rubber tube part will be subjected to the torsional force caused by its bending direction, so as to ensure the quality of hydraulic pipe in subsequent application, to improve the stability and reliability of hydraulic pipe in production process.

[0040] As Figure 2As shown, in the embodiment, the driving mechanism 2 is further limited to better drive the two abutting clamping jaws 31 to move. Specifically, the driving mechanism 2 is arranged as a synchronous cylinder, which is internally provided with synchronous opening and closing blocks fixedly connected with the two abutting clamping jaws 31, for controlling the two abutting clamping jaws 31 to move in the direction of moving away from or moving close to each other.

[0041] It should be noted that, in order to improve the positioning effect on the joint part, the side of the two righting inserts 32 close to each other is arranged as a V-shaped structure, so that the positioning effect on the joint part is better.

[0042] In other embodiments, the inner side wall of the two abutting clamping jaws 31 is fixedly provided with a connecting plate 4, and the connecting plate 4 is provided with a waist-shaped groove, the righting insert 32 is connected with the connecting plate 4 through a fastener, and one end of the fastener passes through the waist-shaped groove and is in close contact or separated from the upper surface of the connecting plate 4, so that the spacing between the two righting inserts 32 is adjustable, so as to be suitable for clamping and positioning the joint parts of different sizes.

[0043] In further embodiments, in order to improve the clamping effect on the sleeve, the end of the two abutting clamping jaws 31 close to each other is formed with a card slot in isosceles trapezoidal structure.

[0044] As Figure 5 shown, in order to further ensure the hydraulic pipe crimping forming effect, a detection sensor 5 is additionally provided for detecting whether the joint part of the hydraulic pipe is connected in place with the rubber pipe part.

[0045] Among them, the detection direction of the detection sensor 5 is perpendicular to the moving direction of the two abutting clamping jaws 31, so as to prevent interference between the detection sensor 5 and the abutting clamping jaws 31.

[0046] And, the detection sensor 5 is provided with two, and is symmetrically arranged on both sides of the abutting clamping jaw 31.

[0047] In a specific example, since the joint part of the hydraulic pipe has a ring-shaped card slot interface, in the normal state, the ring-shaped card slot interface will be hidden inside the sleeve, so the detection sensor 5 can judge whether the joint part of the hydraulic pipe is installed in place in the vertical direction by detecting whether the ring-shaped card slot interface exists. In other examples, other judgment parameters can also be used for detection, such as detecting the exposed length of the joint part of the hydraulic pipe, etc., which is prior art, so it is not described here.

[0048] In further embodiments, the bracket 1 has a support plate 11 for mounting the driving mechanism 2.

[0049] The extension direction of the support plate 11 is perpendicular to the conveying direction (e.g. the direction Va in the figure) of the hydraulic pipe rubber tube part, and the moving direction of the two abutting clamping jaws 31 forms an angle with the extension direction of the support plate 11, and the angle is less than 90°, that is, the abutting clamping jaws 31 and the support plate 11 are staggered, and the normal conveying of the rubber tube part is not affected. Since the detection sensor 5 and the moving direction of the abutting clamping jaws 31 are vertically arranged, the components are all reserved with a gap in the conveying direction of the rubber tube part, so that the hydraulic pipe after the buckling forming can continue to be conveyed in the conveying direction of the rubber tube part, thereby laying the foundation for the automatic production of the hydraulic pipe.

[0050] In a specific example, the angle is 45°, so that the gap formed is the largest, and further prevents the components from interfering with the formed hydraulic pipe.

[0051] 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 belong to the scope of the claims of the present application and the equivalent technologies, the present application also intends to include these modifications and variations.
