Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing and manufacturing technology, and specifically relates to a sealing component insertion tube assembly device. Background Technology

[0002] In the assembly process of the sealing tube, a plastic tube needs to be inserted from one end to the other end of a rubber tube, and then a clamp is used to tighten the joint of the two tubes to form a seal. Currently, the existing assembly method mainly relies on manual labor, that is, the two tubes need to be held by hand and inserted from the ends to complete the assembly.

[0003] However, in actual operation, because the rubber tube is thin and long and easily deformed, it requires repeated manual adjustments to align with the plastic tube from the end. This not only makes the operation difficult and the assembly efficiency low, but also makes it easy for operational errors to cause deviations in the assembly direction of the plastic tube when inserting it into the rubber tube. This results in uneven stress on the inner wall of the rubber tube due to the pressure from the end of the plastic tube, leading to abnormal deformation (such as bulging to one side). This makes it impossible to ensure that the rubber tube tightly covers the plastic tube, affecting the product's sealing performance, resulting in a low product yield and requiring frequent rework and adjustments. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved sealing tube assembly device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A sealing tube assembly apparatus is used for assembling a first pipe and a second pipe. The assembly apparatus includes... The first positioning unit includes a first positioning seat having a first positioning groove, wherein a first pipe is positioned in the first positioning groove and is exposed from one end to form a first plug-in section. The second positioning unit includes a second positioning seat having a second positioning groove, wherein the second pipe is positioned in the second positioning groove and protrudes from one end to form a second insertion section, and the center line of the first insertion section coincides with the center line of the second insertion section. Assemble the driver, which is used to drive the first positioning seat and the second positioning seat to move towards or away from each other along the center line of the first or second plug-in segment. As the first and second positioning seats move towards each other, the first and second plug-in segments are simultaneously plugged into each other from the ends.

[0006] Preferably, the first pipe is a rubber tube, the second pipe is a plastic tube, and the initial diameter of the first insertion segment is smaller than the diameter of the second insertion segment. During assembly, the second insertion segment is inserted into the first insertion segment, causing the first insertion segment to expand outward from the circumference. This creates a plug-in fit, effectively improving the tightness between the first and second insertion segments and enhancing the sealing effect.

[0007] Preferably, the lengths of the first and second connector segments are 1 to 2 times their respective diameters. This arrangement satisfies assembly requirements while ensuring optimal strength of the first and second connector segments, preventing deformation.

[0008] Preferably, when the first and second insertion segments are engaged, the second insertion segment causes the expanded portion of the first insertion segment to abut against one side of the first positioning seat. Here, the first positioning seat limits the relative movement of the first and second insertion segments, improving assembly accuracy.

[0009] Preferably, the first positioning seat and the second positioning seat are arranged side by side at intervals in the horizontal direction, wherein the first positioning groove extends horizontally and passes through one side of the first positioning seat, and the second positioning groove extends horizontally and passes through the side of the second positioning seat opposite to the first positioning seat. Here, the first and second pipes can be positioned horizontally, which facilitates assembly operations.

[0010] Preferably, the first positioning seat includes a first lower seat and a first upper seat located above the first lower seat. The first lower seat has a lower groove formed on its top surface, and the first upper seat has an upper groove formed on its bottom surface. The first positioning unit also includes a first operating component that drives the first upper seat to move up and down. As the first upper seat and the first lower seat align vertically, the upper groove and the lower groove simultaneously join together to form a first positioning groove. Here, the movement of the first upper seat facilitates the loading and unloading of materials in the first pipe.

[0011] Preferably, the first pipe includes a first pipe body and a second pipe body bent from one end of the first pipe body. The first positioning seat also includes an auxiliary seat, wherein the auxiliary seat has an auxiliary positioning groove extending parallel to the second pipe body. The first pipe body is positioned in the first positioning groove, and the second pipe body is simultaneously positioned in the auxiliary positioning groove. Here, when the first pipe is too long and bent, the support and positioning of the auxiliary seat facilitates the rapid positioning of the first pipe.

[0012] Preferably, the second positioning seat includes a second lower seat body and a second upper seat body located above the second lower seat body, wherein the second lower seat body forms a second positioning groove from its top surface; the second positioning unit further includes a second operating member that drives the second upper seat body to move up and down, the second pipe is positioned in the second positioning groove, and the second upper seat body presses the second pipe downward.

[0013] Preferably, the bottom surface of the second upper seat is provided with a cushioning pad.

[0014] Preferably, the assembly driver includes a guide rail extending horizontally, a slide block slidably connected to the guide rail, and a driving component, wherein a second positioning seat is fixedly mounted on the guide rail, and the driving component drives the slide block to reciprocate along the guide rail to move the second positioning seat closer to or away from the first positioning seat. This design is simple and easy to assemble and implement.

[0015] In addition, the assembly equipment includes a reservoir for coating the surfaces of the first and / or second connector segments with lubricant. The lubricant is alcohol, which provides lubrication to facilitate the insertion of the first and second connector segments, while also evaporating quickly and leaving minimal residue.

[0016] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art: In existing technologies, the rubber tube is thin and easily deformed, requiring repeated manual adjustments to align it with the plastic tube from one end. This is not only difficult to operate and inefficient, but also prone to errors during insertion, leading to misalignment of the plastic tube and uneven stress on the inner wall of the rubber tube due to pressure from the plastic tube end. This results in abnormal deformation (e.g., bulging to one side), failing to ensure a tight seal between the rubber and plastic tubes, affecting the product's sealing performance, leading to low yield and frequent rework. This application addresses these shortcomings by comprehensively designing the structure of the sealing tube assembly equipment. The equipment positions the first pipe in the first positioning groove, exposing one end to form the first insertion section, and positions the second pipe in the second positioning groove, exposing one end to form the second insertion section. This ensures the centerlines of the first and second insertion sections coincide. Then, the first and second positioning seats are driven to move towards each other, allowing the first and second insertion sections to simultaneously insert into each other from their ends, completing the assembly. Therefore, compared with the prior art, this utility model, on the one hand, is based on the first and second positioning grooves to position the first and second pipes, and only the exposed parts form the first and second plug-in sections with the center lines coinciding. The precise plug-in assembly is completed in one opposite movement of the first and second plug-in sections, with high assembly accuracy and effectively improving the product yield. On the other hand, it is simple and convenient to operate, and can effectively improve the assembly efficiency. Attached Figure Description

[0024] See Figures 1 to 4 As shown, the sealing tube assembly device of this embodiment is used for assembling the first pipe G1 and the second pipe G2, and includes a first positioning unit 1, a second positioning unit 2 and an assembly driver 3.

[0025] Specifically, the first pipe G1 is a rubber pipe and includes a first pipe body G11 and a second pipe body G12 that bends at 90° from one end of the first pipe body G11; the second pipe G2 is a plastic pipe and includes a main pipe G21 and two branch pipes G22 that are perpendicular to the main pipe G21 and spaced apart side by side along the length of the main pipe G21.

[0026] In this example, the first positioning unit 1 includes a first positioning seat 10 with a first positioning groove c1, wherein the first pipe G1 is positioned within the first positioning groove c1 and protrudes from one end to form a first insertion segment d1; the second positioning unit 2 includes a second positioning seat 20 with a second positioning groove c2, wherein the second pipe G2 is positioned within the second positioning groove c2 and protrudes from one end to form a second insertion segment d2, and the center line of the first insertion segment d1 coincides with the center line of the second insertion segment d2. In this embodiment, the lengths of the first insertion segment d1 and the second insertion segment d2 are 1 to 2 times their respective diameters.

[0027] In some specific embodiments, the first positioning seat 10 and the second positioning seat 20 are arranged side by side at intervals in the horizontal direction, wherein the first positioning groove c1 extends horizontally and passes through one side of the first positioning seat 10, and the second positioning groove c2 extends horizontally and passes through the side of the second positioning seat 20 opposite to the first positioning seat 10. Here, the first and second pipes can be positioned horizontally, which facilitates assembly operations.

[0028] For ease of implementation, the first positioning seat 10 includes a first lower seat 100 and a first upper seat 101 located above the first lower seat 100. The first lower seat 100 has a lower groove c10 formed on its top surface, and the first upper seat 101 has an upper groove c11 formed on its bottom surface. The first positioning unit 1 also includes a first operating member 11 that drives the first upper seat 101 to move up and down. The first operating member 11 adopts a conventional crank-slider mechanism, or it can be driven by a cylinder. As the first upper seat 101 and the first lower seat 100 are vertically aligned, the upper groove c11 and the lower groove c10 are simultaneously joined vertically to form the first positioning groove c1. Here, the movement of the first upper seat facilitates the loading and unloading of materials in the first pipe.

[0029] It should be noted that the first pipe G1 in this embodiment is pre-installed with a clamp so that it can be directly removed and locked in the insertion position after the insertion is completed. Therefore, the first lower seat 100 and the first upper seat 101 in this embodiment are both designed with two intervals to avoid the clamp.

[0030] Meanwhile, the first positioning seat 10 also includes an auxiliary seat 103, wherein an auxiliary positioning groove c3 is formed on the auxiliary seat 103, the extension direction of which is parallel to that of the second tube G12. The first tube G11 is positioned in the first positioning groove c1, with one end extending to form a first insertion section d1, and the second tube G12 is simultaneously positioned in the auxiliary positioning groove c3. Here, when the first pipe is too long and bent, the support and positioning of the auxiliary seat facilitates the rapid positioning of the first pipe.

[0031] In this example, the second positioning seat 20 includes a second lower seat 200 and a second upper seat 201 located above the second lower seat 200, wherein the second lower seat 200 forms a second positioning groove c2 from its top surface; the second positioning unit 2 also includes a second operating member 21 that drives the second upper seat 201 to move up and down. The second operating member 21 adopts a conventional crank-slider mechanism, or it can be driven by a cylinder. The second pipe G2 is positioned in the second positioning groove c2, and the second operating member 21 is manually operated to drive the second upper seat 201 to press the second pipe G2 downward.

[0032] To further facilitate implementation, a buffer pad h is provided on the bottom surface of the second upper body 201. Simultaneously, based on the layout of the main pipe G21 and branch pipe G22 of the second pipeline G2, the second positioning groove c2 correspondingly forms a main positioning groove c21 and a branch positioning groove c22. The main pipe G21 and branch pipe G22 are positioned in the main positioning groove c21 and branch positioning groove c22 respectively, and one end of the main pipe G21 extends out of the main positioning groove c21 to form the second insertion section d2. The advantage of this arrangement is that, during the insertion process, based on the downward pressure constraint and combined with the positioning of the branch pipe by the branch positioning groove, the reverse force experienced during the main pipe insertion can be effectively counteracted.

[0033] In this example, the assembly driver 3 is used to drive the first positioning seat 1 and the second positioning seat 2 to move towards or away from each other along the center line of the first insertion segment d1 or the second insertion segment d2. As the first and second positioning seats move towards each other, the first and second insertion segments are simultaneously inserted into each other from the ends.

[0034] In some specific embodiments, the assembly driver 3 includes a guide rail 30 extending horizontally, a slide block 31 slidably connected to the guide rail 30, and a driving member 32. The second positioning seat 20 is fixedly mounted on the guide rail 30. The driving member 32 drives the slide block 31 to reciprocate along the guide rail 30, causing the second positioning seat 20 to move closer to or away from the first positioning seat 10. The driving member 32 employs a conventional crank-slider mechanism, or it can be driven by a cylinder, allowing for direct manual operation of the driving member 32 for assembly. This design is simple and facilitates assembly and implementation.

[0035] In this embodiment, the initial diameter of the first insertion segment d1 is smaller than the diameter of the second insertion segment d2. During assembly, the second insertion segment d2 is inserted into the first insertion segment d1, causing the first insertion segment d1 to expand outward circumferentially. When the first and second insertion segments form a mating fit, the second insertion segment d2 causes the expanded portion of the first insertion segment d1 to abut against one side of the first positioning seat 10. This mating fit effectively improves the tightness between the first and second insertion segments, enhancing the sealing effect. Simultaneously, the first positioning seat limits the relative movement of the first and second insertion segments, improving assembly accuracy.

[0036] Furthermore, the assembly equipment in this embodiment also includes a reservoir 4 for coating the surfaces of the first insertion segment d1 and / or the second insertion segment d2 with lubricant. The lubricant is alcohol, which provides lubrication to facilitate the insertion of the first and second insertion segments, while also preventing alcohol from evaporating and leaving residue.

[0037] The top of the liquid storage tank 4 is open, allowing the first connector section d1 to be directly inserted into the liquid storage tank 4 and soaked in alcohol before positioning and assembly, even before the first pipe G1 is positioned. In summary, after adopting this sealing tube assembly equipment, the first pipe is positioned in the first positioning groove and exposed from one end to form the first insertion section, and the second pipe is positioned in the second positioning groove and exposed from one end to form the second insertion section, so that the center line of the first insertion section and the center line of the second insertion section can be kept coincident. Then, the first positioning seat and the second positioning seat are driven to move towards each other, so that the first and second insertion sections are simultaneously inserted and matched from the ends to complete the assembly. Therefore, compared with the prior art, this utility model has several advantages. First, it positions the first and second pipes using the first and second positioning grooves, with only the exposed parts forming the first and second insertion segments whose center lines coincide. Precise insertion assembly is completed in a single relative movement of the first and second insertion segments, resulting in high assembly accuracy and effectively improving product yield. Second, it is simple and convenient to operate, effectively improving assembly efficiency. Third, when forming the insertion fit, it effectively improves the tightness between the first and second insertion segments, enhancing the sealing effect. Simultaneously, the first positioning seat limits the relative movement of the first and second insertion segments, improving assembly accuracy. Fourth, during the insertion process, based on the downward pressure restriction and the positioning of the branch pipe using the branch positioning groove, it effectively counteracts the reverse force experienced by the main pipe insertion.

[0038] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
