The existing automatic pressing mechanism lacks effective response mechanism when facing such complex working conditions, and cannot guarantee that the joint part can be accurately inserted in place with high success rate. Once the hydraulic pipe with such defects is misjudged as qualified product and installed in engineering machinery or precision equipment, it will cause a series of serious consequences.

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.

[0039] The utility model will be described in more detail in the following paragraphs with reference to the drawings. The advantages and features of the utility model will be more clear according to the following description. It should be noted that the drawings are all very simplified and use non-precise proportions, and are only used to facilitate and clearly assist the purpose of describing the embodiment of the utility model.

[0040] Embodiment one

[0041] As Figure 3 and Figure 4 The utility model discloses a hydraulic pipe assembly auxiliary device for the auxiliary connection between hydraulic pipe joint part, sleeve and rubber tube part.

[0042] Among them, the hydraulic pipe assembly auxiliary device includes frame 1, rubber tube positioning assembly 2 and telescopic push assembly 3.

[0043] Rubber tube positioning assembly 2 is arranged on frame 1, and is used for positioning and clamping rubber tube part.

[0044] It should be noted that the clamping of rubber tube part is completed by rubber tube positioning assembly 2, so that the sleeve set in rubber tube part is located above rubber tube positioning assembly 2, so as to adjust the relative position of sleeve and joint part by telescopic push assembly 3, and ensure the subsequent buckling effect.

[0045] Specifically, telescopic push assembly 3 is arranged on the upper surface of rubber tube positioning assembly 2 and can be extended to contact the sleeve arranged at the end of rubber tube part, push the sleeve to shake, so that the joint part inserted in the sleeve, the sleeve and the axial line of the opening of rubber tube part are located in the same vertical plane, so that the step part of the joint part is located above the cavity formed by the sleeve at this time, so as to ensure that the step part of the joint part does not form a jamming condition with the end face of the sleeve during the subsequent buckling operation, that is, to ensure that the joint part is always inserted in place during assembly, thereby effectively improving the stability of the hydraulic pipe forming.

[0046] In other embodiments, the hydraulic pipe assembly auxiliary device further includes lifting buckling assembly 4 and detection assembly 5 to complete the buckling operation of the joint part and the hose part of the hydraulic pipe, and lays a foundation for the automatic production of the hydraulic pipe.

[0047] Specifically, lifting buckling assembly 4 is arranged on frame 1 and located above the clamping center point of rubber tube positioning assembly 2, and is used for completely buckling the joint part into the sleeve to complete the connection of the joint part and the rubber tube part.

[0048] Among them, detection assembly 5 is located on one side of lifting buckling assembly 4, and is used for detecting the descending height of lifting buckling assembly 4, and monitoring whether the joint part is buckled in place according to the descending height of lifting buckling assembly 4, that is, can provide a negative feedback for the external terminal (not shown in the figure), so that the external terminal can complete the control of telescopic push assembly 3 according to the feedback result, and realize the automatic production of the hydraulic pipe.

[0049] In one specific example, when the detection assembly 5 detects that the descending height of the lifting and pressing assembly 4 is inconsistent with the preset height, it indicates that there is interference in the pressing process of the lifting and pressing assembly 4, such as interference between the stepped portion of the joint part and the sleeve. Therefore, at this time, the external terminal will control the telescopic pushing assembly 3 to operate to extrude the sleeve, so that the stepped portion of the joint part is located directly above the cavity formed by the sleeve, and then drive the lifting and pressing assembly 4 to operate, so as to realize the automatic pressing function of the hydraulic pipe and improve the production rate.

[0050] In further embodiments, the lifting and pressing assembly 4 is further limited so that the detection assembly 5 can better detect the height of the lifting and pressing assembly 4.

[0051] Specifically, one side of the lifting and pressing assembly 4 is provided with a connecting piece 41, which extends to the detection end face directly above the detection assembly 5. That is, the connecting piece 41 is lowered synchronously with the lifting and pressing assembly 4 during operation. Therefore, the detection assembly 5 can detect the vertical distance between the connecting piece 41 and the detection end face to complete the detection of the descending height of the lifting and pressing assembly 4.

[0052] In one specific example, the detection assembly 5 is provided as a laser sensor.

[0053] In other embodiments, the detection assembly 5, the lifting and pressing assembly 4, the rubber pipe positioning assembly 2 and the telescopic pushing assembly 3 are provided with two groups, respectively located on both sides of the rack 1, for auxiliary connection between the sleeve provided at the two end openings of the rubber pipe part and the plug part, so that the two ends of the hose part of the hydraulic pipe can be pressed at the same time to further improve the production rate of the hydraulic pipe.

[0054] Among them, the rubber pipe positioning assembly 2 includes two symmetrical and opposite moving clamping cylinders and a positioning plate connected with the output end of the clamping cylinder.

[0055] In addition, the telescopic pushing assembly 3 includes a telescopic cylinder and a pushing plate connected with the output end of the telescopic cylinder. The telescopic cylinder is arranged on one side of the positioning plate, and the pushing plate is located above the positioning plate. By extruding the movement of the pushing plate, the relative shaking between the sleeve and the joint part is caused, so that the stepped portion of the joint part can be located directly above the cavity formed by the sleeve.

[0056] It should be noted that, in order to improve the extrusion and pushing effect of the sleeve, the side of the positioning plate in contact with the sleeve is provided with a V-shaped structure.

[0057] Embodiment two

[0058] As Figure 5As shown, the embodiment also proposes a hydraulic pipe auxiliary assembly method, specifically comprising the following steps:

[0059] Providing a hydraulic pipe, which comprises a rubber tube part, a sleeve arranged at an opening of the rubber tube part, and a joint part inserted into the sleeve;

[0060] Mounting the hydraulic pipe on the rack 1, so that the rubber tube positioning assembly 2 clamps the rubber tube part of the hydraulic pipe;

[0061] Controlling the lifting and pressing assembly 4 to descend and press, so as to completely press the joint part into the sleeve, complete the connection between the joint part and the rubber tube part, and the detection assembly 5 detects whether the descending height of the lifting and pressing assembly 4 is consistent with the preset height;

[0062] If consistent, it is judged that the hydraulic pipe pressing is qualified, the rubber tube positioning assembly 2 is controlled to release the hydraulic pipe, and the hydraulic pipe is transported to the next process;

[0063] If inconsistent, it is judged that the hydraulic pipe pressing is unqualified, and the telescopic pushing assembly 3 is controlled to extrude the sleeve, so that the sleeve and the joint part shake relative to each other until the axial lines of the joint part, the sleeve and the opening of the rubber tube part are located in the same vertical plane, and the joint part is pressed to the specified position under the action of the lifting and pressing assembly 4, and the pressing of the hydraulic pipe is completed.

[0064] It should be particularly pointed out that, since the joint part and the sleeve are both arranged as smooth metal materials, the friction force between the step of the joint part and the end face of the sleeve is small, so that when the lifting and pressing assembly 4 keeps the pressing action, the two can still shake relative to each other under the extrusion action of the telescopic pushing assembly 3 to be located in the same vertical plane, so that the lifting and pressing assembly 4 completes the pressing operation of the hydraulic pipe without retracting, saves the extra beat steps required in the hydraulic pipe assembly process (i.e. saves the step of repeatedly pressing after the lifting and pressing assembly 4 is retracted), and improves the assembly rate of the hydraulic pipe.

[0065] It should be further pointed out that the generation of the above judgment result and the control operation of each component are generated and controlled by an external terminal.

[0066] Through the above steps, the pressing operation of the hydraulic pipe can be quickly completed, and after the pressing is completed, the joint part is always pressed in place, thereby effectively improving the stability of the hydraulic pipe forming and laying a foundation for the automatic production of the hydraulic pipe.

[0067] 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 equivalent technologies, the present application also intends to include these modifications and variations.
