Technical Field

[0001] This invention relates to the field of pipe processing equipment, and in particular to a device and method for automatically installing steel cores and aluminum sleeves on automotive air conditioning pipes. Background Technology

[0002] like Figure 1 As shown, the existing automotive air conditioning pipe is assembled from a pipe body 11, an aluminum sleeve 12, and a steel core 13. A toothed structure 16 is provided on the outer side of one end of the pipe body 11. The aluminum sleeve 12 is fixedly assembled to the outer side of one end of the pipe body 11, and the steel core 13 is installed on the inner side of one end of the pipe body 11. To fix the aluminum sleeve 12, two extrusion structures need to be machined on the pipe body 11, and one end of the aluminum sleeve 12 is fixed between the two extrusion structures.

[0003] The production process of this automotive air conditioning pipe requires at least the following steps: 1. Machining one extrusion structure on the pipe body; 2. Performing gear hobbing on the outer side of one end of the pipe body 11; 3. Assembling the aluminum sleeve 12 onto the pipe body 11 and machining another extrusion structure on the pipe body; 4. Pressing the steel core 13 into one end of the pipe body 11.

[0004] In the existing processing method, the above-mentioned processes need to be completed at different workstations. After the workpiece completes the previous process, it needs to be manually transferred to the next workstation for processing. Moreover, the degree of automation in the processing process is low, and the processing needs to be completed manually. The loading process of aluminum sleeves and steel cores also needs to be completed manually. This results in high labor costs and low automation and processing efficiency in the entire processing process. Summary of the Invention

The aluminum sleeve waiting seat has an aluminum sleeve receiving groove that can accommodate a single aluminum sleeve, and the steel core waiting seat has a steel core receiving groove that can accommodate a single steel core. The moving device is equipped with two grippers, which are used to grip the aluminum sleeve and the steel core, respectively.

[0012] Preferably, the material waiting component further includes a bracket, with both the aluminum sleeve waiting seat and the steel core waiting seat mounted on the bracket. The bracket is equipped with a mounting frame, which in turn is equipped with an aluminum sleeve pressing cylinder and a steel core pressing cylinder. The aluminum sleeve pressing cylinder is positioned above the end of the aluminum sleeve discharge guide rail near the aluminum sleeve waiting seat, and the steel core pressing cylinder is positioned above the end of the steel core discharge guide rail near the steel core waiting seat.

[0013] Preferably, the aluminum sleeve mounting punch includes a connecting component, a stamping rod, a sliding sleeve, a spring, and a mandrel. One end of the stamping rod is connected to the connecting component. The stamping rod has a cavity, and the mandrel is located within the cavity. A tube-accommodating annular groove is formed between the mandrel and the inner wall of the cavity to accommodate the tube. One end of the tube-accommodating annular groove has a pressing end face. The sliding sleeve is slidably connected to the outside of the stamping rod. The spring is located between the sliding sleeve and the connecting component. An extrusion forming annular groove is provided on the inner side of one end of the stamping rod. When installing the aluminum sleeve, the aluminum sleeve is fitted onto the stamping rod, with one end of the aluminum sleeve abutting against the sliding sleeve. The inner flange structure at the other end of the aluminum sleeve abuts against the first extrusion structure on the tube. The tube extends into the tube-accommodating annular groove, and one end of the tube contacts the pressing end face. The stamping rod applies axial pressure to the tube, forming a second extrusion structure on the tube. The second extrusion structure is formed in the extrusion forming annular groove, and the inner flange structure on the aluminum sleeve is sandwiched between the first and second extrusion structures.

The screw passes through the first screw through hole on the connecting component and the second screw through hole on the stamping rod and then connects to the threaded hole on the mandrel.

[0016] A method for automatically installing a steel core and aluminum sleeve on an automotive air conditioning pipe includes the following specific steps:

[0017] Step 1: Clamp the tube body using the clamping components;

[0018] Step 2: The shifting drive mechanism drives the shifting moving seat to move so that the extrusion punch is facing the tube body. The stamping feed mechanism drives the extrusion punch to move towards the tube body to form the first extrusion structure on the tube body. Then the stamping feed mechanism drives the stamping head to move so that the tube body exits the stamping head.

[0019] Step 3: The shifting drive mechanism drives the shifting moving seat to move so that the gear hobbing device is facing the tube body. The stamping feed mechanism drives the gear hobbing device to move towards the tube body so that the gear hobbing device reaches the gear hobbing position. The gear hobbing device performs gear hobbing on the tube body to form a gear hobbing structure on the outer surface of the tube body. Then the stamping feed mechanism drives the gear hobbing device to move so that the tube body exits the gear hobbing device.

[0020] Step 4: The shifting drive mechanism drives the shifting moving seat to move so that the chamfering device is facing the tube body. The stamping feed mechanism drives the chamfering device to move towards the tube body so that the gear hobbing device reaches the chamfering position. The chamfering device then performs chamfering on the tube body. Subsequently, the stamping feed mechanism drives the chamfering device to move so that the tube body exits the chamfering device.

[0021] Step 5: The aluminum sleeve and steel core are loaded onto the aluminum sleeve mounting punch and steel core mounting punch respectively using the aluminum sleeve and steel core automatic feeding device.

[0022] Step Six: The shifting drive mechanism drives the shifting moving seat to move so that the aluminum sleeve installation punch faces the tube body. The stamping feed mechanism drives the aluminum sleeve installation punch to move towards the tube body, and installs the aluminum sleeve onto the tube body through the aluminum sleeve installation punch. During the installation of the aluminum sleeve, the aluminum sleeve is fitted onto the stamping rod, one end of the aluminum sleeve abuts against the sliding sleeve, and the inner flange structure of the other end of the aluminum sleeve abuts against the first extrusion drum structure on the tube body. The tube body extends into the tube body receiving annular groove and one end of the tube body contacts the top pressing end face. The stamping rod applies axial pressure to the tube body to form a second extrusion drum structure on the tube body. The second extrusion drum structure is formed in the extrusion drum forming annular groove. The inner flange structure on the aluminum sleeve is sandwiched between the first extrusion drum structure and the second extrusion drum structure. After the aluminum sleeve is installed, the stamping feed mechanism drives the aluminum sleeve installation punch to move so that the tube body exits the aluminum sleeve installation punch.

[0023] Step 7: The shifting drive mechanism drives the shifting moving seat to move so that the steel core installation punch is facing the tube body. The stamping feed mechanism drives the steel core installation punch to move towards the tube body and presses the aluminum sleeve into the tube body through the steel core installation punch. After the steel core is pressed in, the stamping feed mechanism drives the steel core installation punch to move so that the tube body is removed from the steel core installation punch.

[0024] Preferably, in step five, the specific method for loading the aluminum sleeve and steel core onto the aluminum sleeve mounting punch and steel core mounting punch respectively using the automatic aluminum sleeve and steel core feeding device is as follows: The aluminum sleeves stored in the aluminum sleeve vibratory plate are discharged one by one along the aluminum sleeve discharge guide rail, and the aluminum sleeve at the end of the aluminum sleeve discharge guide rail moves to the aluminum sleeve receiving groove on the aluminum sleeve waiting seat; the aluminum sleeves stored in the steel core vibratory plate are discharged one by one along the steel core discharge guide rail, and the steel core at the end of the steel core discharge guide rail moves to the steel core receiving groove on the aluminum sleeve waiting seat; the two grippers on the moving device respectively grip the aluminum sleeve in the aluminum sleeve receiving groove and the steel core in the steel core receiving groove, and the moving device moves the aluminum sleeve and steel core to the aluminum sleeve mounting punch and steel core mounting punch respectively, and then puts the aluminum sleeve and steel core onto the aluminum sleeve mounting punch and steel core mounting punch respectively.

[0025] The beneficial effects of this invention are:

The feed moving seat 310 is provided with a stamping component 38, a gear hobbing device 35, and a chamfering device 36. The stamping component 38 is provided with an extrusion punch 312, an aluminum sleeve mounting punch 313, and a steel core mounting punch 314.

[0049] The extrusion punch 312 is used to extrude the tube body 11 to form a first extrusion structure 14 on the tube body 11. The aluminum sleeve mounting punch 313 is used to assemble the aluminum sleeve 12 to the outside of one end of the tube body 11. The steel core mounting punch 314 is used to install the steel core 13 to the inside of one end of the tube body 11.

[0050] The shifting drive mechanism includes a rack 34 mounted on the frame 2 and a shifting drive motor 33 mounted on the shifting moving seat 31. The rack 34 is parallel to the first guide rail 32, and a gear is connected to the shifting drive motor 33, meshing with the rack 34. The shifting drive motor 33 drives the gear to rotate, and the engagement between the gear and the rack 34 enables the shifting moving seat 31 to move along the first guide rail 32. The movement of the shifting moving seat 31 along the first guide rail 32 is for the purpose of shifting, allowing any processing device on the shifting moving seat 31 to align with the clamping mold component 5 and process the tube 11 on the clamping mold component 5. The stamping feed mechanism 37 drives the feed moving seat 310 to move along the second guide rail 311, which is for the feeding movement of the processing device or the stamping movement of the punch.

[0051] The automatic aluminum sleeve and steel core feeding device 4 is used to feed the aluminum sleeve 12 and the steel core 13 onto the aluminum sleeve mounting punch 313 and the steel core mounting punch 314, respectively.

[0052] Specifically, the automatic aluminum sleeve and steel core feeding device 4 includes an aluminum sleeve vibratory feeder 42, a steel core vibratory feeder 43, an aluminum sleeve discharge guide rail 44, a steel core discharge guide rail 45, a moving device 48, and a waiting component 47.

The aluminum sleeve waiting seat 472 is provided with an aluminum sleeve receiving groove that can accommodate a single aluminum sleeve 12, and the steel core waiting seat 473 is provided with a steel core receiving groove that can accommodate a single steel core 13. The moving device 48 is provided with two grippers 49, which are used to grip the aluminum sleeve 12 and the steel core 13 respectively. The aluminum sleeve discharge guide rail 44 and the steel core discharge guide rail 45 are slightly inclined downward at the end near the waiting component 47, with an inclination angle of 3-5 degrees. The vibration of the linear vibrator 46 can cause the aluminum sleeve 12 and the steel core 13 on the aluminum sleeve discharge guide rail 44 and the steel core discharge guide rail 45 to move towards the waiting component 47.

[0053] In this embodiment, the moving device 48 is a three-axis servo moving device 48, which can drive the gripper 49 to move along the X-axis, Y-axis and Z-axis, realizing the movement of the gripper 49 in three-dimensional space. The gripper 49 is a cylinder gripper 49.

[0054] Furthermore, the material waiting component 47 also includes a fixed frame 41 and a support 471. The support 471, aluminum sleeve vibratory plate 42, and steel core vibratory plate 43 are all mounted on the fixed frame 41. The linear vibrator 46 is placed between the fixed seat and the steel core discharge guide rail 45 or the aluminum sleeve discharge guide rail 44. The aluminum sleeve waiting seat 472 and the steel core waiting seat 473 are both mounted on the support 471. The support 471 is equipped with a mounting frame 474, which is U-shaped. The mounting frame 474 is equipped with an aluminum sleeve pressing cylinder 475 and a steel core pressing cylinder 476.

[0055] The aluminum sleeve mounting punch 313 includes a connecting component 315, a stamping rod 316, a sliding sleeve 317, a spring 318, and a mandrel 319. The connecting component 315 is fixedly connected to the stamping component 38. One end of the stamping rod 316 is connected to the connecting component 315. The stamping rod 316 has a cavity, and the mandrel 319 is located in the cavity. The mandrel 319 and the stamping rod 316 are arranged coaxially. A tube receiving annular groove 323 is formed between the mandrel 319 and the inner wall of the cavity to accommodate the tube 11. One end of the tube receiving annular groove 323 is provided with a pressing end face 324. The sliding sleeve 317 is slidably connected to the outside of the stamping rod 316 and can slide along the axial direction of the stamping rod 316. The spring 318 is disposed between the sliding sleeve 317 and the connecting component 315. The outside of the stamping rod 316 is provided with a limiting end face 320 for limiting the sliding sleeve 317. An extrusion forming annular groove 322 is provided on the inner side of one end of the stamping rod 316.

[0056] When installing the aluminum sleeve 12, the aluminum sleeve 12 is fitted onto the stamping rod 316. One end of the aluminum sleeve 12 abuts against the sliding sleeve 317, and the other end of the aluminum sleeve 12 is provided with an inner flange structure 121. Under the action of the spring 318, the sliding sleeve 317 abuts against the end of the aluminum sleeve 12 away from the inner flange structure 121. The spring 318 applies an axial pushing force to the aluminum sleeve 12, causing the inner flange structure 121 at the other end of the aluminum sleeve 12 to abut against the first extrusion structure 14 on the tube body 11; the tube body 11 extends into the tube body container. The tube body 11 is in contact with the top pressure end face 324 in the annular groove 323. The tube body 11 is axially pressed by the stamping rod 316 to make a certain position on the tube body 11 protrude outward to form a second extrusion drum structure 15. The second extrusion drum structure 15 is formed in the extrusion drum forming annular groove 322. The inner flange structure 121 on the aluminum sleeve 12 is sandwiched between the first extrusion drum structure 14 and the second extrusion drum structure 15. The aluminum sleeve 12 is fixed by the first extrusion drum structure 14 and the second extrusion drum structure 15.

[0057] Furthermore, the connecting component 315 is provided with a first screw through hole, the stamping rod 316 is provided with a second screw through hole, and the mandrel 319 is provided with a threaded hole. The connecting component 315, the stamping rod 316 and the mandrel 319 are connected by screws. The screw passes through the first screw through hole on the connecting component 315 and the second screw through hole on the stamping rod 316 and then connects to the threaded hole on the mandrel 319.

[0058] The steel core 13 can be fitted onto the steel core mounting punch 314. When installing the steel core 13, the steel core 13 is first fitted onto the steel core mounting punch 314. The tube body 11 and the steel core mounting punch 314 are arranged coaxially. The steel core mounting punch 314 moves toward the tube body 11 and the steel core 13 is pressed into the tube body 11 by the punching action of the steel core mounting punch 314.

[0059] A method for automatically installing a steel core 13 and an aluminum sleeve 12 into an automotive air conditioning pipe includes the following specific steps:

[0060] Step 1: Clamp the tube 11 using the clamping mold component 5. The tube 11 is fed manually by manually placing it onto the clamping mold component 5.

[0061] Step 2: The shifting drive mechanism drives the shifting moving seat 31 to move so that the extrusion punch 312 is facing the tube body 11. The stamping feed mechanism 37 drives the extrusion punch 312 to move towards the tube body 11 so that the first extrusion structure 14 is formed on the tube body 11. Then the stamping feed mechanism 37 drives the stamping head to move so that the tube body 11 exits the stamping head.

[0062] Step 3: The shifting drive mechanism drives the shifting moving seat 31 to move so that the hobbing device 35 faces the tube body 11. The stamping feed mechanism 37 drives the hobbing device 35 to move towards the tube body 11 so that the hobbing device 35 reaches the hobbing position. The hobbing device 35 performs hobbing on the tube body 11 to form a hobbing structure 16 on the outer surface of the tube body 11. Then the stamping feed mechanism 37 drives the hobbing device 35 to move so that the tube body 11 exits the hobbing device 35.

[0063] Step 4: The shifting drive mechanism drives the shifting moving seat 31 to move so that the chamfering processing device 36 is facing the tube body 11. The stamping feed mechanism 37 drives the chamfering processing device 36 to move towards the tube body 11 so that the gear hobbing processing device 35 reaches the chamfering processing position. The chamfering processing device 36 performs chamfering processing on the tube body 11. Then the stamping feed mechanism 37 drives the chamfering processing device 36 to move so that the tube body 11 exits the chamfering processing device 36.

[0064] Step 5: The aluminum sleeve 12 and steel core 13 are respectively loaded onto the aluminum sleeve mounting punch 313 and the steel core mounting punch 314 by the aluminum sleeve and steel core automatic feeding device 4.

[0065] The specific method of this step is as follows: Aluminum sleeves 12 stored in aluminum sleeve vibratory plate 42 are discharged one by one along aluminum sleeve discharge guide rail 44, and the aluminum sleeve 12 at the end of aluminum sleeve discharge guide rail 44 is moved to the aluminum sleeve receiving groove on aluminum sleeve waiting seat 472; aluminum sleeves 12 stored in steel core vibratory plate 43 are discharged one by one along steel core discharge guide rail 45, and steel core 13 at the end of steel core discharge guide rail 45 is moved to the steel core receiving groove on aluminum sleeve waiting seat 472; two grippers 49 on moving device 48 respectively grip aluminum sleeve 12 in aluminum sleeve receiving groove and steel core 13 in steel core receiving groove, and move aluminum sleeve 12 and steel core 13 to aluminum sleeve mounting punch 313 and steel core mounting punch 314 respectively through moving device 48, and put aluminum sleeve 12 and steel core 13 onto aluminum sleeve mounting punch 313 and steel core mounting punch 314 respectively. When the gripper 49 grips the aluminum sleeve 12 and the steel core 13, the steel core pressing cylinder 476 and the aluminum sleeve pressing cylinder 475 extend and press down on the steel core 13 and the aluminum sleeve 12 below. The pressed aluminum sleeve 12 is adjacent to the aluminum sleeve 12 in the aluminum sleeve receiving groove, and the pressed steel core 13 is adjacent to the steel core 13 in the steel core receiving groove. After the gripper 49 removes the steel core 13 and the aluminum sleeve 12 from the steel core receiving groove and the aluminum sleeve receiving groove, the steel core pressing cylinder 476 and the aluminum sleeve pressing cylinder 475 release the pressed steel core 13 and the aluminum sleeve 12, so that the next steel core 13 and aluminum sleeve 12 can enter the empty steel core receiving groove and the aluminum sleeve receiving groove.

[0066] Step Six: The shifting drive mechanism drives the shifting moving seat 31 to move, so that the aluminum sleeve mounting punch 313 is facing the tube body 11. The stamping feed mechanism 37 drives the aluminum sleeve mounting punch 313 to move towards the tube body 11, and the aluminum sleeve 12 is installed onto the tube body 11 through the aluminum sleeve mounting punch 313. When installing the aluminum sleeve 12, the aluminum sleeve 12 is fitted onto the stamping rod 316, one end of the aluminum sleeve 12 abuts against the sliding sleeve 317, and the inner flange structure 121 of the other end of the aluminum sleeve 12 abuts against the first extrusion drum structure 14 on the tube body 11; the tube body 11 extends... The tube body 11 is inserted into the annular groove 323 and one end of the tube body 11 is in contact with the top pressing end face 324. The tube body 11 is axially pressed by the stamping rod 316 to form a second extrusion drum structure 15 on the tube body 11. The second extrusion drum structure 15 is formed in the extrusion drum forming annular groove 322. The inner flange structure 121 on the aluminum sleeve 12 is sandwiched between the first extrusion drum structure 14 and the second extrusion drum structure 15.
