Description

Technical Field

[0001] The invention relates to the field of hydraulic pipe production, and in particular to a hydraulic pipe assembly auxiliary device and an auxiliary assembly method. Background Art

[0002] With the rapid development of industries such as engineering machinery and precision equipment manufacturing, the market demand for hydraulic pipes, as key fluid transmission components, has shown a trend of sustained and substantial growth. During the assembly process of hydraulic pipes, the sleeve, joint and hose parts need to be buckled, and whether the joint part is inserted to the bottom directly affects the final quality of the hydraulic pipe.

[0003] In the traditional hydraulic pipe assembly process, the operator mainly relies on manual perception of the insertion of the connector. The operator judges whether the connector has been inserted to the appropriate position at the bottom of the hose through visual observation and hand touch. However, this manual detection method has many disadvantages. On the one hand, human visual judgment is easily disturbed by factors such as lighting conditions, viewing angles, and visual fatigue, making it difficult to accurately determine whether the insertion depth of the connector meets the standard. On the other hand, the accuracy of manual perception depends largely on the experience and skill level of the operator. The judgment criteria of different operators may vary, and long-term repetitive operations can easily lead to distraction and negligence, which inevitably leads to errors and omissions, causing some hydraulic pipes that do not meet the qualified assembly standards to flow into the next production link.

[0004] In recent years, the application of automated production lines in the field of hydraulic pipe manufacturing has gradually become popular, aiming to improve production efficiency and product quality stability. However, new problems have arisen in the process of automated assembly. Due to the gap between the sleeve and the hose, the sleeve is prone to non-directional shaking under the mechanical action of the automated equipment. Figure 1 and Figure 2 As shown, the sleeve 62 and the plug part 63 provided on the hose part 61 will be bent, which will cause the step part of the joint part 63 to get stuck with the sleeve 62 when the joint part 63 is pressed down, that is, it cannot be smoothly inserted downward to the predetermined position. The existing automatic pressing mechanism lacks an effective response mechanism when facing such complex working conditions, and cannot ensure that the joint part can be accurately plugged into place with a high success rate. Once a hydraulic pipe with such defects is misjudged as a qualified product and installed on engineering machinery or precision equipment, a series of serious consequences will occur. In mild cases, oil leakage will occur, which will not only affect the normal operation of the equipment, but also cause pollution to the working environment and waste of materials; in severe cases, it may cause hydraulic system failure, cause serious safety accidents, and pose a huge threat to the life safety of operators.

[0005] Therefore, a hydraulic pipe assembly auxiliary device and an auxiliary assembly method are needed to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a hydraulic pipe assembly auxiliary device and an auxiliary assembly method, so that during the assembly process of the hydraulic pipe in an automated production line, the connection effect between the joint part and the hose part can be guaranteed, that is, to ensure that the joint part is always plugged in place during the assembly process, thereby effectively improving the stability of the hydraulic pipe forming.

[0007] In order to solve the above technical problems, the present invention provides a hydraulic pipe assembly auxiliary device, which is used for auxiliary connection between the hydraulic pipe joint part, the sleeve and the hose part;

[0008] The hydraulic pipe assembly auxiliary device comprises a frame, a hose positioning component and a telescopic pushing component;

[0009] The hose positioning assembly is arranged on the frame and is used to position and clamp the hose.

[0010] The telescopic pushing assembly is arranged on the upper surface of the hose positioning assembly and can be extended to contact the sleeve arranged at the end of the hose part, pushing the sleeve to shake, so that the joint part inserted on the sleeve, the sleeve and the axis line of the opening of the hose part are located in the same vertical plane.

[0011] Furthermore, it also includes a lifting and pressing assembly;

[0012] The lifting and pressing assembly is arranged on the frame and is located just above the clamping center point of the hose positioning assembly, and is used to completely press the joint part into the sleeve to complete the connection between the joint part and the hose part.

[0013] Further, a detection component is also included;

[0014] The detection component is located on one side of the lifting and pressing component, and is used to detect the descending height of the lifting and pressing component, and monitor whether the joint part is buckled in place according to the descending height of the lifting and pressing component.

[0015] Furthermore, a connecting piece is provided on one side of the lifting and pressing assembly;

[0016] The connecting piece extends to just above the end surface detected by the detection component.

[0017] Furthermore, the detection component is configured as a laser sensor.

[0018] Furthermore, the detection component, the lifting and pressing component, the hose positioning component and the telescopic pushing component are each provided with two groups, and are respectively located on both sides of the frame, for auxiliary connection between the sleeves provided at the openings at both ends of the hose part and the plug part.

[0019] Furthermore, the hose positioning assembly includes two symmetrical clamping cylinders that move in opposite directions and a positioning plate connected to the output ends of the clamping cylinders.

[0020] Furthermore, the telescopic pushing assembly includes a telescopic cylinder and a pushing plate connected to the output end of the telescopic cylinder;

[0021] The telescopic cylinder is arranged on one side of the positioning plate, and the pushing plate is located above the positioning plate.

[0022] Furthermore, the side of the positioning plate in contact with the sleeve is configured as a V-shaped structure.

[0023] On the other hand, the present invention also provides a hydraulic pipe auxiliary assembly method, which specifically comprises the following steps:

[0024] A hydraulic pipe is provided, the hydraulic pipe comprising a hose portion, a sleeve arranged at an opening of the hose portion, and a joint portion inserted into the sleeve;

[0025] Install the hydraulic pipe on the frame so that the hose positioning assembly clamps the hose part of the hydraulic pipe;

[0026] Control the lifting and pressing assembly to lower and press, so as to completely press the joint part into the sleeve, and complete the connection between the joint part and the hose part. At the same time, the detection assembly detects whether the lowering height of the lifting and pressing assembly is consistent with the preset height;

[0027] If they are consistent, it is judged that the hydraulic pipe is crimped and qualified, and the hose positioning assembly is controlled to release the hydraulic pipe, so that the hydraulic pipe is transported to the next process;

[0028] If there is inconsistency, the hydraulic pipe is judged to be unqualified. At the same time, the telescopic pushing assembly is controlled to extrude the sleeve, so that the sleeve and the joint part shake relative to each other until the axis lines of the joint part, sleeve and hose opening are in the same vertical plane, and under the action of the lifting and crimping assembly, the joint part is pressed down to the specified position to complete the crimping of the hydraulic pipe.

[0029] Compared with the prior art, the present invention has at least the following beneficial effects:

[0030] By arranging the hose positioning component and the telescopic pushing component, when the joint part of the hydraulic pipe is connected to the hose part, the hose part of the hydraulic pipe can be limited by the hose positioning component first, and then the outer wall of the sleeve can be squeezed by the telescopic pushing component to push the sleeve to shake, so that the axis lines of the joint part, the sleeve and the opening of the hose part are located in the same vertical plane, so that during the subsequent buckling, the joint part can be buckled in place, thereby achieving the purpose of auxiliary buckling, thereby effectively improving the stability of the hydraulic pipe forming.

[0031] Furthermore, by setting up a lifting and crimping component and a detection component, the lifting and crimping component is used to complete the crimping connection between the hydraulic pipe joint part and the hose part, and the detection component is used to detect the lifting height of the lifting and crimping component to provide negative feedback on whether the joint part and the hose part are crimped in place. For example, when the lifting and crimping component does not descend to the preset height, it indicates that a jam has formed between the step portion of the joint part and the upper end surface of the sleeve, and an external control terminal is required to control the telescopic pushing component to extrude the sleeve, so that the relative position between the sleeve and the joint part is fine-tuned until the joint part, the hose part and the sleeve are located in the same vertical plane, thereby repeatedly running the lifting and crimping component to complete the crimping operation, laying the foundation for the automated production of hydraulic pipes.

[0038] The hydraulic pipe assembly auxiliary device and auxiliary assembly method of the present invention will be described in more detail below in conjunction with schematic diagrams, wherein preferred embodiments of the present invention are shown, and it should be understood that those skilled in the art may 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.

[0039] 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.

[0040] Embodiment 1

[0041] like Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a hydraulic pipe assembly auxiliary device, which is used for auxiliary connection between a hydraulic pipe joint part, a sleeve and a hose part.

[0042] The hydraulic pipe assembly auxiliary device includes a frame 1, a hose positioning component 2 and a telescopic pushing component 3.

[0043] The hose positioning assembly 2 is arranged on the frame 1 and is used to position and clamp the hose.

[0044] It should be noted that the hose part is clamped by the hose positioning component 2, so that the sleeve sleeved on the hose part is located above the hose positioning component 2, so that the relative position of the sleeve and the joint part can be adjusted by the telescopic pushing component 3 to ensure the subsequent buckling effect.

[0045] Specifically, the telescopic pushing assembly 3 is arranged on the upper surface of the hose positioning assembly 2, and can be extended to contact the sleeve arranged at the end of the hose part, push the sleeve to shake, so that the joint part inserted on the sleeve, the sleeve and the axial center line of the opening of the hose part are located in the same vertical plane. Therefore, at this time, the step part of the joint part is located directly above the chamber formed by the sleeve, so as to ensure that during the subsequent buckling operation, the step part of the joint part and the end face of the sleeve will not be stuck, that is, to ensure that the joint part is always plugged in place during the assembly process, thereby effectively improving the stability of the hydraulic pipe forming.

[0046] In other embodiments, the hydraulic pipe assembly auxiliary device also includes a lifting and crimping component 4 and a detection component 5 to complete the crimping operation of the hydraulic pipe joint part and the hose part, laying a foundation for the automated production of hydraulic pipes.

[0047] Specifically, the lifting and pressing assembly 4 is arranged on the frame 1 and is located just above the clamping center point of the hose positioning assembly 2, and is used to completely press the joint part into the sleeve to complete the connection between the joint part and the hose part.

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

[0049] In a specific example, when the detection component 5 detects that the descending height of the lifting and crimping component 4 is inconsistent with the preset height, it indicates that there is interference in the crimping process of the lifting and crimping component 4, such as interference between the step portion of the joint and the sleeve. Therefore, the external terminal will control the telescopic pushing component 3 to operate to squeeze the sleeve so that the step portion of the joint is located directly above the chamber formed by the sleeve, and then drive the lifting and crimping component 4 to operate, thereby realizing the automatic crimping function of the hydraulic pipe and improving the production rate.

[0050] In a further embodiment, the lifting and pressing assembly 4 is further limited so that the detection assembly 5 can better detect the height to which the lifting and pressing assembly 4 is lowered.

[0051] Specifically, a connecting piece 41 is provided on one side of the lifting and crimping assembly 4, and the connecting piece 41 extends to just above the end face detected by the detection assembly 5, that is, the lifting and crimping assembly 4 synchronously drives the connecting piece 41 to descend during operation, so the detection assembly 5 can complete the detection of the descending height of the lifting and crimping assembly 4 by detecting the vertical distance between the connecting piece 41 and its detection end face.

[0052] In a specific example, the detection component 5 is configured as a laser sensor.

[0053] In other embodiments, the detection component 5, the lifting and crimping component 4, the hose positioning component 2 and the telescopic pushing component 3 are each provided with two groups, and are respectively located on both sides of the frame 1, and are used for auxiliary connection between the sleeves provided at the openings at both ends of the hose part and the plug part, so that both ends of the hose part of the hydraulic pipe can be crimped at the same time, so as to further improve the production rate of the hydraulic pipe.

[0054] The hose positioning assembly 2 includes two symmetrical clamping cylinders that move in opposite directions and a positioning plate connected to the output ends of the clamping cylinders.

[0055] In addition, the telescopic pushing assembly 3 includes a telescopic cylinder and a pushing plate connected to 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. Through the movement and extrusion of the pushing plate, the sleeve and the joint part shake relative to each other, so that the step part of the joint part can be directly above the chamber formed by the sleeve.

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

[0057] Embodiment 2

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

[0059] A hydraulic pipe is provided, the hydraulic pipe comprising a hose portion, a sleeve arranged at an opening of the hose portion, and a joint portion inserted into the sleeve;

[0060] Install the hydraulic pipe on the frame 1, so that the hose positioning assembly 2 clamps the hose part of the hydraulic pipe;

[0061] Control the lifting and pressing assembly 4 to lower and press, so as to completely press the joint part into the sleeve, and complete the connection between the joint part and the hose part. At the same time, the detection assembly 5 detects whether the lowering height of the lifting and pressing assembly 4 is consistent with the preset height;

[0062] If they are consistent, it is judged that the hydraulic pipe is crimped and qualified, and the hose positioning component 2 is controlled to release the hydraulic pipe, so that the hydraulic pipe is transported to the next process;

[0063] If they are inconsistent, the hydraulic pipe is judged to be unqualified in the crimping. At the same time, 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 axis lines of the joint part, the sleeve and the opening of the hose part are in the same vertical plane, and under the action of the lifting and crimping assembly 4, the joint part is pressed down to the specified position to complete the crimping of the hydraulic pipe.

[0064] It should be particularly noted that since the joint part and the sleeve are both set to smooth metal material, the friction force between the step at the joint part and the end face of the sleeve is relatively small. Therefore, when the lifting and crimping assembly 4 maintains the downward pressing action, the two can still shake relative to each other under the squeezing action of the telescopic pushing assembly 3 so as to be located in the same vertical plane, thereby allowing the lifting and crimping assembly 4 to complete the crimping operation of the hydraulic pipe without retracting, saving the unnecessary beat steps required in the hydraulic pipe assembly process (i.e., saving the step of repeating the downward pressing after the lifting and crimping assembly 4 is retracted), thereby improving the assembly rate of the hydraulic pipe.

[0065] It should also be noted that the generation of the above-mentioned judgment results and the control operation of each component are all generated and controlled by an external terminal.

[0066] Through the above steps, the crimping operation of the hydraulic pipe can be completed quickly, and it is ensured that after the crimping is completed, the joint part is always crimped in place, thereby effectively improving the stability of the hydraulic pipe forming and laying the foundation for the automated production of the hydraulic pipe.

[0067] 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.
