[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0042] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely to illustrate some embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of the present invention can be combined with each other.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] like Figures 1-9 As shown, this embodiment proposes a high-precision linkage feeding mechanism for processing automotive air conditioning vehicle-mounted pipe fittings, including: a pipe feeding machine 1 for processing automotive air conditioning vehicle-mounted pipe fittings, a control structure 2 for adjusting different diameters of pipe fittings, a universal support structure 3 for adapting and supporting the pipe fittings during movement, and a sleeve structure 4.

[0045] Specifically, according to Figure 1 and Figure 9 As shown, in a preferred embodiment, based on the above method, the control structure 2 further includes a rotating plate 21, a control cylinder 22, a bracket 23 and a linkage shaft 24. The control structure 2 is located at the feeding end of the pipe feeder 1. The two ends of the rotating plate 21 are respectively connected to the control cylinder 22 and the bracket 23 through the positioning shaft 37. The control cylinder 22 slides left and right along the feeding end of the pipe feeder 1.

[0046] In practical use, when the pipe enters the pipe feeder 1, the automotive air conditioning pipe comes into contact with the rotating plate 21 and is clamped by the clamping assembly and enters the pipe feeder 1. In order to keep the automotive air conditioning pipe horizontal with the feeding direction during the movement, the parameters of the sensor group are transmitted to the controller. By controlling the movement of the control cylinder 22, the two ends of the rotating plate 21 are pushed to rotate under the limitation of the linkage shaft 24. During the rotation, the angle between the rotating plate 21 and the bracket 23 changes, thereby pushing the center of the automotive air conditioning pipe to be in the same axial direction as the feeding direction. In this way, the automotive air conditioning pipe can be easily moved without causing deviation and damage to the pipe.

[0047] Specifically, according to Figure 2 and Figures 5-7As shown, in a preferred embodiment, based on the above method, a further universal support structure 3 is provided for the adaptation support during the movement of the pipe fitting. The universal support structure 3 includes a support plate 31, a rotating rod 33, and a linkage rod 38 for adjusting the up and down movement of the support plate on the pipe fitting feeder 1. The top of the support plate 31 is provided with multiple sets of support grooves 32 of different diameters for supporting pipe fittings of different diameters. The movable end of the linkage rod 38 is provided with a positioning shaft 37, which is used to connect to the bottom of the rotating rod 33. The outer end of the rotating rod 33 is provided with a telescopic spring 36, and the lower end of the rotating rod 33 is provided with a hexagonal slider 34 and a hexagonal groove 35 for positioning the support plate 31 after rotation. The outer end of the telescopic spring 36 is provided with a movable groove for the up and down movement of the rotating rod 33.

[0048] The support plate 31 is fixedly connected to the rotating rod 33, the center of the rotating rod 33 is fixedly connected to the hexagonal slider 34, the hexagonal slider 34 slides up and down along the hexagonal groove 35, one end of the telescopic spring 36 is fixed to the lower end of the rotating rod 33, and the other end of the telescopic spring 36 is fixed in the movable groove.

[0049] The lower end of the rotating rod 33 is provided with an extension rod, the lower end of which is rotatably connected to the positioning shaft 37. The positioning shaft 37 is movably connected to the linkage rod 38. The outer ends of the extension rod and the positioning shaft 37 are provided with extension grooves for sliding. Both the extension groove and the movable groove are located at the inner end of the pipe feeder 1. The outer end of the linkage rod 38 extends out of the outer side of the pipe feeder 1.

[0050] The universal support structure 3 is designed to facilitate the interaction between automotive air conditioning pipes of different diameters and the corresponding support grooves 32. In the initial state, if there is a mismatch, the extension rod connected to the positioning shaft 37 can be moved downward by pressing the linkage rod 38. After the extension rod moves downward, the hexagonal slider 34 moves downward into the movable groove, and the restriction between it and the hexagonal groove 35 is released. At this time, the support plate 31 can rotate. The rotation of the support plate 31 is achieved by the movable groove and the rotating rod 33. The extension rod fixedly connected to the rotating rod 33 rotates along the positioning shaft 37, thereby ensuring the stability of the rotation of the support plate 31. When the corresponding support groove 32 is in the feeding direction, the return of the telescopic spring 36 causes the hexagonal slider 34 to be locked into the hexagonal groove 35 again, thus limiting the position of the support plate 31.

[0051] After the adjustment of the support groove 32 is completed, the linkage rod 38 has a self-locking structure. The self-locking structure can be implemented by a pin with an elastic structure in the prior art, or by other structures that can achieve self-locking. There are no restrictions here, as long as self-locking can be achieved. This is conducive to ensuring the stability of the universal support structure 3.

[0052] Specifically:

[0053] The self-locking mechanism can be a mechanical spring pin. A series of positioning holes are made on the side wall of the linkage rod 38 or the housing of the pipe feeder 1. A spring pin (such as a ball plunger) is fixed on the linkage rod 38. When the linkage rod 38 is pushed or rotated to a specific position (i.e., the position where the support groove 32 is aligned), the ball of the spring pin automatically engages in the corresponding positioning hole under the action of the spring force, thus achieving self-locking. When readjustment is required, the pull ring on the linkage rod 38 is manually pulled outward to overcome the spring force and make the ball disengage from the positioning hole, thereby releasing the lock.

[0054] Self-locking can also be achieved using an electromagnetic lock. An electromagnetic lock body is installed at the end of the stroke or at the rotation limit of the linkage rod 38, and a locking tongue is installed at the corresponding position on the linkage rod 38. When the controller receives the positioning signal from the "support groove 32 positioning sensor", it will send an energizing signal to the electromagnetic lock. The electromagnetic lock generates magnetic force to attract the locking tongue and firmly lock the linkage rod 38. When adjustment is needed, the controller issues a command to de-energize the electromagnetic lock, which will release the linkage rod 38.

[0055] Specifically, according to Figure 4 , Figure 6 and Figure 8 As shown, in a preferred embodiment, based on the above method, the sleeve structure 4 further includes a telescopic member 43 for wrapping the protective sleeve during the pipe feeding process and a cutting structure for cutting the pipe. The outer end of the telescopic member 43 is connected to the sleeve body 42 and the external sleeve frame 41. The wrapping end of the sleeve body 42 is provided with a positioning member 47. The cutting structure includes a first cutting position 44 and a second cutting position 45 located at both ends of the telescopic member 43.

[0056] The sleeve body 42 is wound around the external sleeve frame, and the sleeve body 42 is linked in the telescopic member 43 through the positioning member 47. The telescopic member 43 includes a telescopic cylinder 431 and a telescopic sleeve 432. The fixed end of the telescopic cylinder 431 is fixedly connected to the second cutting position 45.

[0057] The movable end of the telescopic cylinder 431 is fixedly connected to the first cutting position 44, and a positioning block 46 is fixed to the outer end of the first cutting position 44.

[0058] The positioning component 47 is embedded inside the positioning block 46. The positioning component 47 includes two sets of mirror-symmetrical arc grooves 471 and arc rods 472. The inner arc surface of the arc rod 472 is provided with annularly arranged tooth grooves 473. The outer end of the tooth grooves 473 is linked to a linkage gear 474. The center of the linkage gear 474 is provided with a rotating rod 475. The center of the rotating rod 475 is provided with a positioning rod 476. The positioning rod 476 is fixed inside the positioning block 46. One end of the rotating rod 475 is connected to a linkage belt. The outer side of the rotating rod 475 is provided with a linkage motor.

[0059] The lower ends of the first cutting position 44 and the second cutting position 45 are respectively provided with moving cylinders 48, and the outer ends of the moving cylinders 48 are provided with moving grooves.

[0060] Specifically, sleeves are installed at the outer ends of the automotive air conditioning pipes, such as the low-pressure pipe: Low-pressure pipes typically need to be wrapped to prevent abnormal low-pressure refrigerant conditions caused by high temperatures in the engine compartment;

[0061] In specific operation, the telescopic component 43 can confirm the specific sleeve length of each automotive air conditioning vehicle pipe through the telescopic cylinder 431. During the sleeve process, the outer protective sleeve can achieve a dust-free environment for the installation between the automotive air conditioning vehicle pipe and the sleeve body 42. The telescopic cylinder 431 pushes the first cutting position 44 and the positioning block 46 to move. Finally, the distance between the first cutting position 44 and the second cutting position 45 is confirmed by infrared sensors, etc., so as to control the length of the sleeve body 42 and the length of the automotive air conditioning vehicle pipe of this model.

[0062] Before and after cutting the automotive air conditioning pipe fitting, the positioning component 47 is connected to the outside of the movable end of the sleeve body 42. The positioning component 47 is connected to the movable end of the sleeve body 42 and is clamped to the outer end of the sleeve body 42 by moving outward through the movable arc rod 472, so as to ensure that the sleeve body 42 is stable at the head end of the connection and to ensure the full connection of the sleeve.

[0063] The movement of the arc-shaped rod 472 is driven by the linkage motor to rotate the two sets of rotating rods 475 connected by the linkage belt along the corresponding positioning rod 476. During the rotation of the positioning rod 476, the corresponding linkage gear 474 is pushed to rotate. The linkage gear 474 meshes with the tooth groove 473 outside the corresponding arc-shaped rod 472, thereby pushing the arc-shaped rod 472 to move in and out of the arc groove 471 to ensure the fixation before the sleeve body 42 is connected and the movement before the sleeve body 42 is cut.

[0064] The movable cylinder 48 can drive the telescopic cylinder 431 to adjust the movement of the first cutting position 44 and the second cutting position 45. The movement of the first cutting position 44 and the second cutting position 45 can adjust the overall cutting of the sleeve body 42 and the automotive air conditioning vehicle pipe. When the movable cylinder 48 pushes the first cutting position 44 and the second cutting position 45 to move, it can push the finished automotive air conditioning vehicle pipe to enter the next workshop.

[0065] The first cutting position 44 and the second cutting position 45 both include two cutting blades, one upper and one lower, and one end of the cutting blades moves on the same shaft. The outer side of the shaft is provided with a groove. The open ends of the two cutting blades are respectively provided with cylinders connected to the overall cylinder control assembly. During the opening and closing of the two cutting blades, the shaft moves laterally along the groove, which helps to ensure the stability and completeness of the cutting of the automotive air conditioning pipes.

[0066] To ensure a complete cut, the cutting blade can be configured as a rotating blade driven by a servo motor, and the specific cut can be adjusted up and down via a cylinder connection.

[0067] The cutting blades on the two cutting positions are made of materials that can cut stainless steel, PVC or aluminum pipes with great precision. In practice, the specific material of the cutting blades can be determined based on the actual investment requirements of each production workshop.

[0068] When cutting the automotive air conditioning pipe fitting with a sleeve, the pipe feeding machine 1 moves the fitting to at least the first cutting position 44, and then cuts it through the second cutting position 45 (the second cutting position 45 moves to the outer end of the first cutting position 44 through the telescopic cylinder 431). The first cutting position 44 is an emergency position in actual use for emergency use.

[0069] The position control adjustment in this application is achieved through existing mature technologies, sensor signal transmission, and controller control of cylinders or motors at corresponding positions. In specific use, technicians can adjust the position and model of the sensor and controller, as well as the corresponding wiring connections, as needed, as long as they meet the safety standards in the field of power technology.

[0070] like:

[0071] The alignment sensor for the pipe fitting can be a photoelectric sensor or a laser displacement sensor, which is arranged near the inlet of the pipe fitting feeder 1 to detect the actual position of the pipe fitting to be entered and transmit the position signal to the controller. When the pipe fitting enters, the alignment sensor detects the deviation of its central axis and transmits the signal to the controller. The controller calculates the adjustment amount according to the preset program, and then drives the control cylinder 22 to extend and retract, causing the rotating plate 21 to rotate around the linkage shaft 24, thereby correcting the pipe fitting so that its center coincides with the axis of the feeding direction.

[0072] The positioning sensor of the support groove 32 can be a proximity switch (such as an inductive proximity switch), which is arranged near the movable groove or hexagonal groove 35 of the universal support structure 3. It is used to detect whether the hexagonal slider 34 has accurately fallen into a certain set of hexagonal grooves 35, thereby confirming whether the rotation of the support plate 31 is in place, and feeding back the signal of placement to the controller. When the operator presses the linkage rod 38 and rotates the support plate 31 and then releases it, the telescopic spring 36 pushes the hexagonal slider 34 back into the hexagonal groove 35. After the positioning sensor of the support groove 32 detects the valid signal, it sends the "locking complete" signal to the controller, and the system allows subsequent feeding operations to be carried out to ensure safety.

[0073] The cutting length measuring sensor can be an infrared ranging sensor, arranged on the first cutting position 44 and the second cutting position 45, to measure the distance between the two cutting positions in real time. This distance corresponds to the required sleeve length, and the length signal is transmitted to the controller. The pipe placement sensor can be a photoelectric sensor, arranged at the first cutting position 44, to detect whether the pipe has been delivered to the predetermined cutting position and trigger the cutting action. The operator sets the required sleeve length on the controller's human-machine interface. Based on the feedback from the cutting length measuring sensor, the controller drives the telescopic cylinder 431 to precisely adjust the distance between the first cutting position 44 and the second cutting position 45. When the pipe is delivered to the predetermined position by the moving cylinder 48 and detected by the pipe placement sensor, the controller first controls the linkage motor of the positioning component 47 to move, clamping the sleeve body 42 through the arc rod 472. After the sleeve is completed, the first cutting position 44 and the sleeved pipe body are moved synchronously, and then the cutting is completed by the cutting blade.

[0074] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
