Description

Technical field

[0001] The utility model belongs to the technical field of automobile pipeline manufacturing, in particular to a novel nylon pipe quick connector plugging machine. [Background Technology]

[0002] Nylon tubing is widely used in automobiles, such as fuel systems and vacuum boost systems. These products share a common characteristic: they all require quick connectors. Quick connectors, which connect and disconnect pipes without tools, are widely used in gas, gas-liquid, and oil pressure connections, particularly in automotive fuel lines. Quick connectors are typically assembled manually, which is labor-intensive, lacks guaranteed insertion depth, and results in long cycle times.

[0003] In the prior art, there are related quick connector splicing machines designed to improve the quality and efficiency of splicing. For example, Chinese patent authorization number CN209492185U discloses a new nylon tube quick connector splicing machine, and Chinese patent authorization number CN203650401U discloses a nylon tube and quick connector splicing tool, which can realize automatic expansion of pipe fittings and automatic splicing of connectors and pipe fittings. However, both of the above solutions can only complete the expansion and splicing of one end of a pipe fitting, resulting in low splicing efficiency and unable to meet production needs.

[0004] The pipe assembly device disclosed in Chinese patent publication number CN 118477946A is configured as a dual-station device capable of simultaneously assembling joints at both ends of a pipe, thereby improving the efficiency of pipe splicing. However, this solution is generally used to assemble joints at both ends of a straight pipe and is not suitable for curved pipe fittings. Moreover, in this solution, expansion and splicing are performed simultaneously at both ends of the pipe fitting. If one end is slightly deformed during expansion or splicing, this will affect the expansion and splicing action at the other end, reducing the precision of the splicing and thus the splicing yield.

[0005] Therefore, it is necessary to provide a novel nylon tube quick connector splicing machine to solve the above-mentioned technical problems. [Utility Model Content]

[0006] The main purpose of the utility model is to provide a novel nylon tube quick connector plugging machine, which can improve the plugging accuracy, can adapt to nylon tubes of different sizes and shapes, has good versatility, and can also prevent manual injuries.

[Specific implementation method]

[0029] Please refer to Figures 1-4 The present embodiment is a new nylon tube quick connector plugging machine. The new nylon tube quick connector plugging machine 100 includes a frame 1 and at least one plugging device 2 arranged on the frame 1 and realizing reaming and plugging actions. The plugging device 2 includes a clamping mechanism 21 for clamping the nylon tube, a first support plate 22 arranged on one side of the clamping mechanism 21, a first driving member 23 that drives the first support plate 22 to move left and right to approach or move away from the clamping mechanism 21, a second driving member 24 arranged on the first support plate 22, a second support plate 25 driven by the second driving member 24 to move back and forth, and a reaming cone head 26 and a joint clamp 27 arranged on the second support plate 25. The clamping mechanism 21 is provided with a positioning module 28 for positioning the end of the nylon tube and a camera 29 for taking pictures and detecting the completed plugged product on the side close to the joint clamp 27.

[0030] A waste receiving bin 11 and a sensor 12 for identifying products are provided on the side of the frame 1 . Unqualified products detected by the camera 29 are photographed and placed into the waste receiving bin 11 after being identified by the sensor 12 .

[0031] In this embodiment, two plug-in devices 2 are provided. To save space, the two plug-in devices 2 are arranged in a double layer, one on a workbench 14 of the frame 1, and the other above the workbench 14 via a support frame 13. To facilitate manual operation, the workbench 14 is tilted, with the side facing the operator in a lower position, facilitating manual operation on both plug-in devices 2. In other embodiments, the number and layout of the plug-in devices 2 can be set according to design requirements and are not limited here.

[0032] The first driving member 23 and the second driving member 24 are cylinder driven or servo motors. The first driving member 23 is preferably a servo motor, which can accurately control the insertion depth of the quick-connect connector and the nylon tube.

[0033] The clamping mechanism 21 includes a fixed clamping seat 211 , a movable clamping seat 212 that cooperates with the fixed clamping seat 211 to achieve a clamping action, and a driving module 213 that drives the movable clamping seat 212 to move forward and backward to move closer to or away from the fixed clamping seat 211 .

[0034] The fixed clamp seat 211 includes a fixed base 2111 and a rear clamping fixture 2112 arranged on the fixed base 2111; the movable clamp seat 212 includes a movable base 2121 and a front clamping fixture 2122 arranged on the movable base 2121; the rear clamping fixture 2112 and the front clamping fixture 2122 are both provided with a contoured slot 214 that is contoured to the nylon tube. When the driving module 213 drives the front clamping fixture 2122 to approach the fixed clamp seat 211, the two contoured slots 214 are docked front and back and are jointly clamped on the outer periphery of the nylon tube to achieve the clamping action of the nylon tube. The fixed base 2111 and the rear clamping jig 2112, as well as the movable base 2121 and the front clamping jig 2122 are matched with each other by means of ridges and grooves, and are tightened by screws. When the quick connector is connected to nylon tubes of different shapes, the screws are loosened, the corresponding rear clamping jig 2112 and the front clamping jig 2122 are replaced, and then the screws are tightened to realize the connection of the quick connector of nylon tubes of different shapes, thereby providing versatility of the plug-in device 2. Since the shape of the nylon tube is bent at different angles, one end of the contoured slot 214 is set on the left side of the rear clamping jig 2112 and the front clamping jig 2122 to facilitate the plug-in action with the quick connector. The other end of the contoured slot 214 can be set on the right side of the rear clamping jig 2112 and the front clamping jig 2122 or on the upper surface of the rear clamping jig 2112 and the front clamping jig 2122. This is set according to the specific shape of the nylon tube and is not limited here.

[0035] Since the nylon tube is first placed between the rear clamping jig 2112 and the front clamping jig 2122, and then the driving module 213 drives the front clamping jig 2122 to approach the rear clamping jig 2112 to achieve clamping of the nylon tube, since the back needs to be expanded and plugged in, the driving module 213 will generate a large force to clamp the nylon tube. When the nylon tube is placed manually, the large force generated by the driving module 213 makes the rear clamping jig 2112 and the front clamping jig 2122 clamp the nylon tube. In order to prevent manual clamping, the driving module 213 is provided with two cylinders. The driving module 213 includes a pre-clamping cylinder 2131 that drives the movable base 2121 to move back and forth to achieve the closing and opening actions of the front clamping jig 2122 and the rear clamping jig 2112, and a pre-clamping cylinder 2131 that is pressed on the movable base 2121 to achieve the front clamping jig 2122 and the rear clamping jig The clamping fixture 2112 clamps the clamping piece 2133 of the nylon tube together with the clamping cylinder 2132 that drives the clamping piece 2133 to move forward and backward. The pre-clamping cylinder 2131 drives the front clamping fixture 2122 to move toward the rear clamping fixture 2112 so that the front clamping fixture 2122 and the rear clamping fixture 2112 are closed. Then the clamping cylinder 2132 drives the clamping piece 2133 to press on the moving base 2121 so that the front clamping fixture 2122 and the rear clamping fixture 2112 are closed. The clamping jig 2122 and the rear clamping jig 2112 clamp the nylon tube. The force applied by the pre-clamping cylinder 2131 is relatively small. It is sufficient to close the front clamping jig 2122 and the rear clamping jig 2112 to prevent manual clamping. The force applied by the clamping cylinder 2132 is relatively large, which drives the clamping part 2133 to clamp the front clamping jig 2122 and the rear clamping jig 2112, thereby realizing the clamping action of the nylon tube.

[0036] The positioning module 28 includes a positioning cylinder 281, a third support plate 282 driven by the positioning cylinder 281 to move back and forth, and a positioning block 283 arranged on the third support plate 282. If the length of the inserted nylon tube is different, the thickness of the positioning block 283 can be changed to adapt to nylon tubes of different lengths, which has good flexibility.

[0037] The tip of the reaming cone head 26 is provided with a plurality of oil outlet holes 261 and an oil inlet hole 262 connected to the plurality of oil outlet holes 261. Lubricating oil is injected from the oil inlet hole 262 and enters the plurality of oil outlet holes 261, which can reduce friction and resistance during reaming.

[0038] A receiving groove 271 that is shaped like the quick-connect connector is provided in the connector clamp 27. Before plugging and assembling, the quick-connect connector needs to be placed in the receiving groove.

[0039] When applying the novel nylon tube quick connector plug-in machine 100 provided by the present invention, first, the quick connector is placed into the receiving groove 271 of the connector clamping die 27, the positioning cylinder 281 drives the third support plate 282 to drive the positioning block 283 to extend, and the nylon tube is placed into the contoured slot 214 on the rear clamping fixture 2112 and the front clamping fixture 2122. One end of the nylon tube is positioned on the positioning block 283, and the pre-clamping cylinder 2131 drives the front clamping fixture 2122 to move toward the side of the rear clamping fixture 2112 so that the front clamping fixture 2122 and the rear clamping fixture 2112 are closed, and then the pressing cylinder 2132 drives the pressing member 2133 to press on the movable base 2121 so that the front clamping fixture 2112 is closed. The tightening fixture 2122 and the rear clamping fixture 2112 clamp the nylon tube, the positioning cylinder 281 drives the third support plate 282 to drive the positioning block 283 to retract, the first driving member 23 cooperates with the second driving member 24 to drive the reaming cone 26 to expand the end of the nylon tube, and drives the joint clamp 27 to clamp the quick-connect joint and the nylon tube for plugging. The camera 29 takes pictures of the products after the plugging is completed to confirm whether the plugging is qualified. Qualified products enter the next station to continue operation, and unqualified products are placed in the waste receiving bin 11 after being identified by the sensor 12. The upper and lower plug-in devices 2 complete the plug-in action at the same time, completing the plug-in action of the two nylon tubes, which can effectively improve work efficiency.

[0040] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
