Description

Technical Field

[0001] The utility model relates to the field of automobile manufacturing, in particular to an oiling mechanism for the blade track of the central air outlet of an automobile air conditioner. Background Art

[0002] An automobile air conditioner has multiple air outlets. Among them, as the largest air outlet on the automobile, the structure of the blade assembly inside the central air outlet is as Figure 1 and Figure 2 shown, including a support housing 1 and several blades 2 hinged at intervals along the extension direction of the support housing 1. The blades 2 generally include two groups, and all the blades 2 in each group are linked by a linkage rod 3. Therefore, each blade 2 has a hinge shaft 201 for hinging with the linkage rod 3 and two shaft sections 202 for respectively being clamped into the Ω grooves 101 on both sides of the support housing 1 to realize the hinge connection with the support housing 1.

[0003] For the convenience of assembling the above-mentioned blade assembly, generally, the two groups of blades 2 are placed on a positioning seat at the same time. The structure of the positioning seat can be referred to Figure 3 shown, including a bottom plate 4 and two groups of placing modules 5 fixed on the bottom plate 4 at intervals. Each group of placing modules 5 is recessed with several positioning placing grooves 6 along the blade distribution track in the final blade assembly. When assembling is required, the positioning seat moves to the assembling station. The assembling station generally includes a horizontal seat that can horizontally extend and a lifting seat that can vertically lift. The horizontal seat is equipped with a linkage rod, and the lifting seat is equipped with a support housing. During assembly, the horizontal seat first horizontally extends, and after its extension, directly aligns the two linkage rods with the hinge shafts on the blades and realizes the assembly; then, the horizontal seat retracts and disengages from the linkage rod; then, the lifting seat descends, aligns the support skeleton with the blades, and the shaft sections on the blades are simultaneously clamped into the corresponding Ω grooves on both sides of the support housing to realize the rotational fit.

[0004] Before assembling the blade assembly, it is necessary to coat the above-mentioned hinge shaft and shaft section with lubricating oil. The existing blades are generally horizontally placed at intervals in the placing seat at the oiling station, and the oiling brush in the oiling station reciprocates horizontally between these blades for oiling. This results in that the oiled blades need to change the placing seat, that is, change from the placing seat at the oiling station to the placing seat at the assembling station, resulting in low efficiency. Summary of the Utility Model

[0005] Aiming at the disadvantage that the existing horizontal oiling method requires changing the placing seat between the oiling station and the assembling station for the blades, resulting in reduced efficiency, the utility model provides an oiling mechanism for the blade track of the central air outlet of an automobile air conditioner that does not require changing the placing seat.

[0006] To solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] An oiling mechanism for the blade track of the central air outlet of an automotive air conditioner, comprising a base, a positioning seat arranged on the base and used for positioning and placing the blades, and an oiling module for oiling the blades. A number of positioning and placing grooves are correspondingly arranged on the positioning seat along the blade arrangement track in the blade assembly. The oiling module includes a support plate vertically fixed on the base, a track groove arranged on the support plate along the blade distribution track, and an oiling component. The oiling component includes a mounting seat, three oil brushes respectively arranged on the mounting seat corresponding to the hinge shaft and the shaft section, and a rolling member fixed on the mounting seat and in rolling cooperation with the track groove. The movement of the mounting seat is controlled by a guiding and driving component, and an oil supply component for supplying oil to the oiling brush is arranged on the mounting seat.

[0008] With the above scheme, the above-mentioned positioning seat can be adapted to the assembly station. Since the blades on the positioning seat are in an arc-shaped wave trend, a track groove consistent with the blade distribution is arranged on the support plate, and the mounting seat equipped with the oil brush moves along the track groove to evenly oil the hinge shafts and shaft sections on all the blades. The advantage of this track oiling mechanism is that after oiling, there is no need to take out the blades from the positioning seat, and the positioning seat can be directly moved to the assembly station for assembly, which can save the steps of replacing the positioning seat and thus improve production efficiency.

[0009] Preferably, the guiding and driving component includes a first guide rail horizontally arranged on the support plate along the blade distribution direction, a sliding seat guidingly sliding on the first guide rail, a guiding block fixed on the first sliding seat, and a second guide rail vertically fixed at the bottom of the mounting seat and guidingly sliding with the guiding block. A first cylinder is arranged on the base, and the piston rod of the first cylinder extends and retracts along the sliding direction of the sliding seat, and the end of the piston rod is fixedly connected with the sliding seat.

[0010] With the above scheme, by using the extension and retraction of one cylinder and combining two groups of guiding components arranged in a cross shape, the mounting seat can be made to adaptively slide along the track groove.

[0011] Preferably, the oil supply component includes an oil storage barrel, an oil pipe, and a solenoid valve for opening and closing the oil pipe. The oil pipe is connected between the oil storage barrel and the solenoid valve and between the solenoid valve and the oil brush.

[0012] With the above scheme, the solenoid valve is used to realize the opening and closing of the oil pipe. The lubricating oil in the oil storage barrel can enter the oil brush through the oil pipe, and as the oil brush contacts the hinge shaft or the shaft section, the lubricating oil is coated on the hinge shaft and the shaft section.

[0013] Preferably, the rolling member is a roller or a rotating bearing, and the outer wall of the rolling member fits and cooperates with the two side walls of the track groove.

[0014] With the above scheme, both the roller or the rotating bearing can guide and roll along the track groove to ensure the smoothness of the oiling by the oil brush.

[0015] Preferably, the base is provided with an oiling station, and the oiling module is arranged at the oiling station. An assembly station is arranged on one side of the oiling station on the base. The positioning seat is guided and slid along the blade arrangement direction between the oiling station and the assembly station. The movement of the positioning seat is controlled by a rodless cylinder, and the slider of the rodless cylinder is fixedly connected to the positioning seat.

[0016] With the above solution, two stations can be arranged on the bottom plate, and the positioning seat reciprocates between the two stations. The advantage of the above design is that after the positioning seat is coated with lubricating oil at the oiling station, it can be moved to the assembly station to realize the assembly with the linkage rod and the support housing. The two stations operate continuously, significantly improving production efficiency.

[0017] Preferably, two position sensors corresponding to the oiling station and the assembly station respectively are arranged at the lower end of the base, and an induction tab cooperating with the position sensor is arranged on the slider.

[0018] Preferably, a limit buffer block for restricting the continuous movement of the positioning seat when the positioning seat moves to the oiling station or the assembly station is arranged on the upper end surface of the base.

[0019] Preferably, a positioning component for synchronously positioning all blades is arranged on the positioning seat. The positioning component includes a guide seat horizontally and guidingly inserted on the positioning seat, positioning push rods vertically and parallelly spaced on the guide seat for pressing the corresponding blades against the same side wall of the positioning placement groove, and a stop rod vertically folded towards the blade direction at the end of the positioning push rod away from the guide seat for limiting the upward movement of the blade. A guide groove for guiding the sliding of the guide seat and communicating with the positioning placement groove is arranged on the positioning seat. The guide seat extends outside the positioning seat, and a second cylinder is fixed on the guide seat outside the positioning seat. The piston rod end of the second cylinder is fixedly connected to the positioning seat.

[0020] With the above solution, the width of the positioning placement groove is slightly larger than the width of the blade. As the second cylinder expands and contracts, the positioning push rod can be separated from the blade or push the corresponding blade to fit against one side wall of the positioning placement groove. The angle of the blade after fitting is the angle required during final installation. The design of the stop rod can prevent the upward movement of the blade due to the acting force during the installation of the linkage rod and the hinge shaft.

[0021] Since the present utility model adopts the above technical solutions, it has remarkable technical effects: the positioning seat is guided and moved on the base. In addition to the oiling station, an assembly station can also be arranged on the base. The positioning seat can place the blades according to the arrangement trajectory during blade assembly. In the oiling mechanism, the oil brush can perform adaptive oiling along the arrangement trajectory of the blades. After oiling, the positioning seat can directly enter the assembly station for assembly by moving. This trajectory oiling mechanism can directly move the positioning seat to the assembly station for assembly after oiling, saving the steps of replacing the positioning seat and improving production efficiency.
