Description

[Technical Field]

[0001] This utility model belongs to the field of automotive pipeline processing technology, and in particular relates to an automatic insertion device for double-joint nylon tubes. [Background Technology]

[0002] Nylon hoses for automotive cooling systems typically require quick-connect couplings at both ends for rapid connection to other hoses or quick assembly with the vehicle. Traditional assembly equipment can only assemble the quick-connect coupling at one end of the nylon hose at a time, then switch to assemble the quick-connect coupling at the other end, requiring two separate steps. This is relatively cumbersome, inefficient, and results in a buildup of semi-finished products on the production line. This not only takes up space but also requires repeated handling and loading / unloading, wasting manpower and further reducing assembly efficiency.

[0003] To address this issue, existing technologies include devices for quick-connecting double-ended nylon tubes. For example, Chinese Patent Publication No. CN211072528U discloses an automatic assembly device for double-ended nylon tubes, comprising a base and a clamping device and a plugging device mounted on the base. The clamping device and plugging device are used for clamping the tube body and plugging the tube connector into the tube body, respectively. A lower clamping block is provided between the two plugging devices to effectively fix the tube body in conjunction with the upper clamping block of the clamping device. A sliding platform is provided at the bottom of the plugging device and clamping device at one end of the device, allowing for forward and backward sliding. Both the upper and lower clamping blocks are quick-change structures. The sliding platform allows this design to adapt to products of different lengths, and different diameters can be accommodated by changing the upper and lower clamping blocks. However, the nylon tubing inside automotive cooling systems exhibits complex bends. Although the solution states that certain components can be quickly replaced and adjusted according to product specifications to ensure the fitting angle of the pipe joints, adapting to nylon tubing with different bending angles requires individually adjusting the positions of the clamping device, insertion device, and lower clamping block to ensure their coordination. Since the positions of the clamping device, insertion device, and lower clamping block need to be adjusted separately, one or two must be adjusted first, and then the remaining devices must be matched with the previously adjusted ones. This adjustment is difficult and time-consuming, reducing assembly efficiency.

[0004] Therefore, it is necessary to provide an automatic insertion device for double-joint nylon tubes to solve the above-mentioned technical problems. [Utility Model Content]

[0011] Furthermore, the clamping drive module includes a first drive member, a first push rod that is driven by the first drive member to perform telescopic movement, and a pair of connecting rods rotatably disposed at the end of the first push rod. The other end of the connecting rod is rotatably disposed on the first base, and the second base is fixedly disposed on the connecting rod.

[0012] Furthermore, a handle is provided on the second base, and the handle is fixed to the second base by a second fastener.

[0015] Furthermore, the hole-reducing assembly includes a mounting base disposed on the third support frame and a hole-reducing cone head mounted on the mounting base by a spring. A limit guide rod is disposed on the mounting base, and the spring is sleeved on one end of the limit guide rod.

[0016] Furthermore, the mounting base includes a lower mounting base and an upper mounting base, which are connected and installed by a second fastener.

Detailed Implementation Methods

[0032] Example 1:

[0033] Please refer to Figures 1-5 This embodiment is an automatic double-connector nylon tube splicing device 100. The automatic double-connector nylon tube splicing device 100 includes a frame 1, a first splicing mechanism 2 mounted on the frame 1 for inserting a first quick connector 300 into one end of the nylon tube 200, and a second splicing mechanism 3 mounted on the frame 1 for inserting a second quick connector 400 into the other end of the nylon tube 200. Both the first splicing mechanism 2 and the second splicing mechanism 3 include a base 21 and a clamping module 22 and a splicing module 23 mounted on the base 21. The clamping module 22 is used to clamp the end of the nylon tube 200, and the splicing module 23 is used to enlarge the port of the nylon tube 200 and insert the first quick connector 300 or the second quick connector 400 into the nylon tube 200.

[0034] In this embodiment, to improve the versatility of the insertion device, both the first insertion mechanism 2 and the second insertion mechanism 3 are positionally adjustable on the frame 1 to accommodate nylon tubes 200 of different lengths or bending angles. Both the first insertion mechanism 2 and the second insertion mechanism 3 are mounted to the frame 1 using a first fastener 4. The frame 1 has several positioning holes 11 that mate with the first fastener 4, and the base 21 has several mounting holes 211 that mate with the first fastener 4. The number of positioning holes 11 is greater than the number of mounting holes 21. To adjust the position of the first insertion mechanism 2 or the second insertion mechanism 3, loosen the first fastener 4, move and adjust the position of the first insertion mechanism 2 or the second insertion mechanism 3, then insert the first fastener 4 into both the positioning hole 11 and the mounting hole 211, and tighten the first fastener 4 to fix the first insertion mechanism 2 or the second insertion mechanism 3 onto the frame 1. This allows for position adjustment of the first insertion mechanism 2 or the second insertion mechanism 3, thus adapting to nylon tubes 200 of different lengths or bending angles. A limit block 13 is also provided on the frame 1. After the first insertion mechanism 2 or the second insertion mechanism 3 is adjusted, the limit block 13 is installed on the frame 1 and abuts against the side of the base 21, restricting the movement of the first insertion mechanism 2 or the second insertion mechanism 3 and preventing it from moving during insertion.

[0035] To facilitate the movement of the first insertion mechanism 2 and the second insertion mechanism 3, a handle 212 is provided on the base 21. By gripping the handle 13, the base 21 is moved, thereby adjusting the position of the first insertion mechanism 2 and the second insertion mechanism 3. The handle 13 makes movement more convenient. When adjusting the position of the first insertion mechanism 2 or the second insertion mechanism 3, since the clamping module and the insertion module are fixed on the base, the position of the first insertion mechanism 2 and the second insertion mechanism 3 can be adjusted directly by gripping the handle 13 and moving the base 21. The position adjustment is simple and convenient, solving the problem of long time consumption for position adjustment in the prior art.

[0036] The first fastener 4 can be selected from screws, bolts, and pins, or it can be set to other structures. The specific structure is not limited here, as long as it can achieve the installation and fixation between the base 21 and the frame 1.

[0037] The clamping module 22 includes a first clamping seat 221 for positioning the nylon tube 200, a second clamping seat 222 that cooperates with the first clamping seat 221 to perform clamping action, and a clamping drive module 223 that drives the second clamping seat 222 to perform clamping or opening action with the first clamping seat 221. The first clamping seat 221, the second clamping seat 222 and the clamping drive module 223 are all mounted on a first support frame 226.

[0038] The first clamping seat 221 includes a first base 2211 and a first clamping fixture 2212 disposed on the first base 2211; the second clamping seat 222 includes a second base 2221 and a second clamping fixture 2222 disposed on the second base 2221; both the first clamping fixture 2212 and the second clamping fixture 2222 are provided with contoured slots 224 that conform to the shape of the nylon tube 200. When the clamping drive module 223 drives the second clamping seat 222 to approach the first clamping seat 221, the two contoured slots 224 are spliced ​​together and jointly clamped on the outer periphery of the nylon tube 200, thereby realizing the clamping action of the nylon tube 200. Since the shape of the nylon tube 200 is curved at different angles, the specific structure of the contoured slots 224 is set according to the bending direction of the nylon tube 200, and is not limited here. The first base 2211 and the first clamping fixture 2212, and the second base 2221 and the second clamping fixture 2222, are fitted together by protrusions and grooves, and are tightened by a second fastener. This design of the first clamping base 221 and the second clamping base 222 enables quick replacement of the first clamping fixture 2212 and the second clamping fixture 222. When inserting quick connectors into nylon tubes 200 of different shapes or diameters, loosen the second fastener, replace the corresponding first clamping fixture 2212 and the second clamping fixture 2222, and then tighten the second fastener. This allows for the insertion of quick connectors into nylon tubes of different shapes or diameters, improving the versatility of the first insertion mechanism 2 and the second insertion mechanism 3.

[0039] In this embodiment, the first clamp 221 is located below, and the second clamp 222 is located above the first clamp 221. The first clamp 221 and the second clamp 222 clamp the nylon tube 200 from top to bottom.

[0040] In other embodiments, the first clamp 221 and the second clamp 222 clamp the nylon tube 200 from front to back, or the first clamp 221 and the second clamp 222 clamp the nylon tube 200 from side to side. Correspondingly, the position of the clamping drive module 223 is changed according to the actual situation.

[0041] The clamping drive module 223 includes a first drive member 2231, a first push rod 2232 driven by the first drive member 2231 to perform telescopic movement, and a pair of connecting rods 2233 rotatably disposed at the end of the first push rod 2232. The other end of the connecting rods 2233 is rotatably disposed on a first base 2211, and a second base 2221 is fixedly disposed on the connecting rods 2233. The pin of the first drive member 2231 extends to drive the first push rod 2232 to drive the second clamping seat 222 to press against the first clamping seat 221, thereby realizing the clamping of the nylon tube 200 by the first clamping fixture 2212 and the second clamping fixture 2222.

[0042] Since the nylon tube 200 is first placed between the first clamping fixture 2212 and the second clamping fixture 2222, and then the clamping drive module 223 drives the second clamping fixture 2222 to move closer to the first clamping fixture 2212 to clamp the nylon tube 200, and since subsequent hole enlargement and insertion operations are required, the clamping drive module 223 will generate a large force to clamp the nylon tube 200. When the nylon tube 200 is manually placed, the clamping drive module 223 generates a large force to clamp the nylon tube 200 with the first clamping fixture 2212 and the second clamping fixture 2222. In order to prevent the operator from being clamped, a handle 225 is provided on the second base 2221. The handle 225 is fixed on the second base 2221 by the second fastener. Since both ends of the connecting rod 2233 are rotatable, pressing the handle 225 will cause the second clamp 222 to close with the first clamp 221. A first sensor (not shown in the figure) is provided on the first support frame 226 to detect whether the second clamp 222 and the first clamp 221 are closed. After the first sensor (not shown in the figure) detects that the second clamp 222 and the first clamp 221 are closed, the first drive member 2231 will start to work. The pin of the first drive member 2231 extends to drive the first push rod 2232 to drive the second clamp 222 to press against the first clamp 221, thereby realizing the clamping of the nylon tube 200 by the first clamping fixture 2212 and the second clamping fixture 2222.

[0043] The plug-in module 23 includes a second driving member 231, a second support frame 232 driven by the second driving member 231 to move closer to or further away from the clamping module 22, a third driving member 233 disposed on the second support frame 232, a third support frame 234 driven by the third driving member 233 to move back and forth, and a hole-expanding assembly 235 and a connector clamping mold 236 disposed on the third support frame 234. The second support frame 232 is disposed on the base plate 21 via a slide rail slider, and the third support frame 234 is disposed on the second support frame 232 via a slide rail slider. In order to reduce the size of the first plug-in mechanism 2 and the second plug-in mechanism 3, the second driving member 231 is disposed at the bottom of the first support frame 226.

[0044] The first drive component 2231, the second drive component 231, and the third drive component 233 can be configured as cylinders or servo motors, depending on the actual situation, and are not limited here. A servo motor is preferred, as it can improve the accuracy of the connection.

[0045] The connector clamp 236 has a receiving groove 2361 that conforms to the shape of the quick connector. Before insertion and assembly, the quick connector needs to be placed into the receiving groove 2361. The connector clamp 236 is fixed to the third support frame 234 by a second fastener. If a quick connector of a different structure or size needs to be replaced, the connector clamp 236 can be replaced by loosening the second fastener. This allows it to adapt to quick connectors of different structures or sizes, improving the versatility of the insertion device.

[0046] The hole enlarging assembly 235 includes a mounting base 2351 disposed on the third support frame 234 and a hole enlarging cone 2353 mounted on the mounting base 2351 by a spring 2352. A limit guide rod 2354 is provided on the mounting base 2351, and the spring 2352 is sleeved on one end of the limit guide rod 2354. The reaming cone 2353 is elastically mounted on the mounting base 2351, which facilitates the reaming cone 2353 to make conformal contact with the nylon tube and prevents the reaming cone 2353 from crushing the nylon tube 200. The limit guide rod 2354 can both guide the spring 2352 and limit the reaming cone 2353. After the reaming cone 2353 compresses the spring 2352, the limit guide rod 2354 can control the amount of compression of the spring 2352. When the spring 2352 is compressed to a certain extent, the reaming cone 2353 will simultaneously abut against the spring 2352 and the limit guide rod 2354, which facilitates the subsequent reaming operation of the reaming cone 2353.

[0047] To facilitate the installation of the reaming cone 2353 into the mounting base 2351, the mounting base 2351 is constructed using a splicing method. The mounting base 2351 includes a lower mounting base 23511 and an upper mounting base 23512, which are spliced ​​together by a second fastener. Both the lower and upper mounting bases 23511 and 23512 are provided with a first contoured mounting groove 23513 for mounting the spring 2352, a second contoured mounting groove 23514 for mounting the reaming cone 2353, and a third contoured mounting groove 23515 for mounting the limiting guide rod 2354. The reaming cone 2353 includes a cone 23531 and a mounting shaft 23532. The mounting shaft 23532 is installed within the second contoured mounting groove 23514, while the cone 23531 is located outside the mounting base 2351 to facilitate insertion into the nylon tube 200 for reaming operations. In this embodiment, two upper mounting bases 23512 are provided. When installing the enlarging assembly 235, firstly, the limiting guide rod 2354 is placed into the third contour mounting groove 23515 of the lower mounting base 23511. Then, the spring 2352 is placed into the first contour mounting groove 23513 of the lower mounting base 23511 and sleeved on the limiting guide rod 2354. Next, the first upper mounting base 23512 is assembled onto the lower mounting base 23511 using the second fastener, and the first upper mounting base 23512 is located at the spring 235. 2. Above the limiting guide rod 2354, the limiting spring 2352 and the limiting guide rod 2354 move upward. Then, the mounting shaft 23532 of the reaming cone 2353 is placed in the second imitation mounting groove 23514 of the lower mounting base 23511. Then, the second upper mounting base 23512 is assembled onto the lower mounting base 23511 by the second fastener, and the second upper mounting base 23512 is located above the mounting shaft 23532, limiting the upward movement of the reaming cone 2353, thus completing the installation of the reaming assembly 235. If you need to enlarge the hole of a nylon tube 200 with a different structure or diameter, you need to replace the enlarging cone 2353. Loosen the second fastener, remove the second upper mounting base 23512, replace the enlarging cone 2353, and then tighten the second upper mounting base 23512 to complete the replacement of the enlarging cone 2353. This can adapt to nylon tubes 200 with different structures or diameters and improve the versatility of the plug-in device.

[0048] The second fastener can be selected from screws, bolts, or pins, or it can be set to other structures. The specific structure is not limited here, as long as it can achieve the installation and fixation between various components.

[0049] The frame 1 is equipped with a pair of shelves 12 for holding nylon tubes 200. The connected nylon tubes 200 are placed directly on the shelves 12. After a certain number of nylon tubes 200 have been connected, they can be moved together to the next workstation. The shelves 12 can temporarily store nylon tubes 200, reducing the frequency of unloading and handling. The frame 1 is also equipped with a start button and related wiring system to facilitate the connection process.

[0050] When using the automatic double-joint nylon tube splicing device 100 provided in this solution, the first quick connector 300 is positioned in the receiving groove 2361 of the first splicing mechanism 2, and the second quick connector 400 is positioned in the receiving groove 2361 of the second splicing mechanism 3. Simultaneously, one end of the nylon tube 200 to be assembled is positioned on the clamping module 22 of the first splicing mechanism 2, and the other end of the nylon tube 200 to be assembled is positioned on the clamping module 22 of the second splicing mechanism 3. Both ends of the nylon tube 200 are secured in the contour slots 224 of the first clamping fixture 2212. At the same time, the first splicing mechanism 2 is pressed. The handle 225 of the second insertion mechanism 3 drives the second clamping seat 222 on the two insertion mechanisms to close with the first clamping seat 221. After the first sensor (not shown in the figure) detects that the second clamping seat 222 and the first clamping seat 221 are closed, the first driving member 2231 will start to work. The pin of the first driving member 2231 extends to drive the first push rod 2232 to drive the second clamping seat 222 to press against the first clamping seat 221, realizing the clamping action of the first clamping fixture 2212 and the second clamping fixture 2222 on the nylon tube 200. The clamping module 22 of the first insertion mechanism 2 and the second insertion mechanism 3 Simultaneously clamping both ends of the nylon tube 200, the insertion action of the two ends of the nylon tube begins. The third driving member 233 drives the third support frame 234 to move, so that the reaming cone 2353 of the reaming assembly 235 is aligned with the port of the nylon tube 200. The second driving member 231 drives the second support frame 232 to move towards the clamping assembly 22, so that the reaming cone 2353 performs reaming operation on the port of the nylon tube 200. After the reaming operation is completed, the second driving member 231 and the third driving member 233 are reset. At this time, the first quick connector 300 and the second quick connector 400 are respectively aligned with the port of the nylon tube 200. The driving component 231 drives the second support frame 232 to move towards the clamping assembly 22, assembling the first quick connector 300 and the second quick connector 400 onto the two ends of the nylon tube 200 respectively, completing the assembly of the quick connectors of the nylon tube 200. The second driving component 231 resets, and the handle 225 is turned in the opposite direction, causing the first driving component 2231 to retract. The second clamp 222 and the first clamp 221 open, and the assembled nylon tube 200 is taken out and placed on the shelf 12. Then, a new first quick connector 300, a second quick connector 400, and a nylon tube 200 are placed to begin the next round of assembly.

[0051] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
