Description

Technical Field

[0001] The utility model relates to the field of automobile manufacturing, in particular to an assembly mechanism for assembling a blade and a retaining frame. Background Art

[0002] A Chinese patent with announcement number CN214492478U discloses an automobile air-conditioning outlet structure, including a shell assembly and a front blade assembly, a left blade assembly and a right blade assembly arranged in the shell assembly. The front blade assembly, the left blade assembly and the right blade assembly have roughly the same structure, all of which include a plurality of parallel blades and a connecting rod for realizing synchronous rotation of the blades. The shell assembly includes a shell and an upper and lower retaining frame and a left and right retaining frame clamped in the shell. The left and right retaining frames are rotatably connected to the rotating shafts at both ends of the front blade, and the upper and lower retaining frames are rotatably connected to the rotating shafts at both ends of the left blade and the right blade.

[0003] The retainer and the blades are assembled first, and then the retainer and the housing are assembled. This assembly method is gentler than the assembly method of directly installing the blades on the housing, and can avoid the breakage problem caused by the deformation of the rotating shafts at both ends of the blades during the latter assembly.

[0004] The existing assembly method generally adopts manual installation. During manual installation, since multiple blades need to be connected to one retaining frame, and retaining frames need to be installed at both ends of the blade, during manual installation, the retaining frame and the blade can only be assembled one by one, which has the problem of low assembly efficiency. Utility Model Content

[0005] The utility model aims at the disadvantage of low efficiency of manual assembly of existing blades and retaining frames, and provides an assembly mechanism for assembling blades and retaining frames, which can significantly improve the assembly efficiency of blades and retaining frames.

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

[0007] An assembly mechanism for assembling a blade and a retainer, comprising a base, a blade placement seat being fixed on the base, a placement groove for placing a blade individually recessed at parallel intervals at the upper end of the blade placement seat, a movable assembly component which can carry the retainer and accurately install the retainer on the shaft of the blade as it moves is arranged on the base, the movable assembly component comprising movable blocks arranged on both sides of the blade placement seat on the base and which can move relatively close to or away from the axial direction of the shaft of the blade, two positioning pins which can be fully retracted into the movable block or partially extended out of the movable block are elastically and telescopically arranged on one side directly opposite to the two movable blocks, the positioning pins are coaxially opposite to the shaft of the blade and can be inserted into the shaft hole of the retainer.

[0008] By adopting the above scheme, all blades corresponding to a product can be placed on the blade placement seat. After the axial hole on the retaining frame is inserted into the positioning pin, the retaining frame can be installed on the movable block. The retaining frame can move synchronously with the movement of the movable block. The positioning pin is coaxially arranged with the axis of the blade. The positioning pin also has a positioning effect, that is, the axial hole of the retaining frame is automatically aligned with the axis of the blade. When the movable block carries the retaining frame to move toward the blade placement seat and moves to the specified position, the two retaining frames can be directly installed at both ends of the blade. This assembly mechanism can effectively improve the assembly efficiency.

[0009] Preferably, the movable block is arranged on a movable plate, and the movable plate is moved on the base along the axial direction of the blade axis through a guide driving component, and an anti-detachment mechanism is provided between the movable plate and the movable block, which limits the retaining frame to detach from the blade as the movable block moves away from the blade placement seat after the retaining frame is installed on the blade axis.

[0010] Preferably, the anti-slip mechanism includes a fixed block fixed on the movable plate, a lifting rod fixed on the fixed block and horizontally plugged into the movable block, and a second cylinder, the cylinder body of the second cylinder is fixed on the movable plate and the end of the piston rod of the second cylinder is fixedly connected to the end of the movable block away from the blade placement seat.

[0011] By adopting the above scheme, the blades can rotate smoothly relative to the retaining frame. Therefore, the connection between the blade shaft and the axial hole of the retaining frame is relatively loose. When the movable block is away from the blade placement seat, the friction between the movable block and the retaining frame can easily cause the retaining frame to separate from the blade. After the ejecting rod is set, when the movable block separates from the retaining frame, the position of the ejecting rod remains unchanged, and the retaining frame is always pressed against the two ends of the blade, thereby preventing the retaining frame from separating from the blade.

[0012] Preferably, the guide drive component includes a guide rail fixed on the base, a slider fixed to the lower end of the movable plate and slidingly guided by the guide rail, and a first cylinder fixed on the base. A mounting plate is vertically arranged on the lower end surface of the movable plate, and the piston rod end of the first cylinder is fixedly connected to the mounting plate.

[0013] Preferably, a positioning module capable of positioning all blades is provided on the blade placement seat, the positioning module comprising a first positioning mechanism capable of limiting the placement position of the blade in the placement groove along the moving direction of the movable block, and a second positioning mechanism capable of simultaneously limiting the placement position of the blade in the placement groove along the moving direction vertical to the movable block and preventing the blade from moving upward.

[0014] Preferably, the first positioning mechanism includes a positioning block which is raised and lowered on the blade placement seat and is used to position one end of all blades when rising and can allow the movable block to pass through after descending. The lifting and lowering of the positioning block is controlled by a third cylinder, which is vertically mounted on the lower end surface of the base and the end of the piston rod of the third cylinder is fixedly connected to the bottom of the positioning block.

[0015] By adopting the above scheme, after the positioning block rises, it blocks one end of the placement slot. After the operator places the blade, one end of the blade abuts against the positioning block, which can ensure that all blades are correctly placed along the moving direction of the movable block; after the positioning block descends, it can give way to the movable block, ensuring that the movable block can smoothly install the retaining frame on the shaft of the blade.

[0016] Preferably, the second positioning mechanism includes at least one group of resisting components that can reciprocate in a direction perpendicular to the moving direction of the movable block. The resisting component includes a movable rod and a plurality of resisting blocks fixed on the movable rod at vertical intervals, the number and spacing of which are consistent with the placement grooves. A movable groove that penetrates the placement groove and is perpendicular to the placement groove is provided on the blade placement seat. The movable rod and the blade guide move in the movable groove. The upper end of the resisting block is vertically folded in the direction of the blade abutment to form a block for preventing the blade from moving up. A fourth cylinder for driving the movable rod to move is provided on the base.

[0017] By adopting the above scheme, in the resisting assembly, the blocking block and the stopper move synchronously. As the blocking block and the stopper move back and forth, the complete placement groove can be exposed or the placement groove can be entered and the blade can be pressed against one side wall of the placement groove. All blades have the same movement trend to ensure the angle they need to cooperate with the retaining frame. When the retaining frame is installed on the shaft of the blade, the blade will have an upward component force, and the block can prevent the blade from moving upward.

[0018] Due to the adoption of the above technical scheme, the utility model has significant technical effects: all blades corresponding to a product can be placed on the blade placement seat, and the setting of the positioning module can ensure that the blade is in a state where it can be directly installed with the retaining frame on the blade placement seat; after the axial hole on the retaining frame is inserted into the positioning pin, the retaining frame can be installed on the movable block, and the retaining frame can move synchronously with the movement of the movable block, and the positioning pin is coaxially arranged with the axis of the blade, and the positioning pin also has a positioning effect, that is, the axial hole of the retaining frame is automatically aligned with the axis of the blade, and when the movable block carries the retaining frame to move toward the blade placement seat and moves to the specified position, the two retaining frames can be directly installed at both ends of the blade; the push rod can prevent the friction between the movable block and the retaining frame from causing the retaining frame and the blade axis to be separated when the movable block retreats, and the assembly mechanism can effectively improve the assembly efficiency.
