Description

Technical Field

[0001] The utility model belongs to the technical field of assembly, and particularly relates to an assembly jig for an automotive center air duct. Background Art

[0002] The housing of the automotive center air duct is composed of a top plate and side walls. There are two side walls, which are respectively connected to both sides of the top plate to form a receiving cavity with an opening downward. Currently, all existing automotive center air ducts are special-shaped plastic parts. During the production process, in order to reduce production costs, sometimes the automotive center air duct needs to be split into upper and lower molds for molding. After molding, the plastic parts are manually buckled to form an integral automotive center air duct. In order to provide the sealing performance of the automotive center air duct, multiple plastic part buckling points are usually set. During the buckling process, the plastic parts may be deformed due to excessive pressure on a certain buckling point. Once the upper and lower plastic parts are deformed, it is easy to cause buckling misalignment, and then the buckle or lock cannot be aligned, and it is more likely to occur the situation of failure in pressing and installing the buckle. On the one hand, it reduces the working efficiency of assembly, and on the other hand, it also makes the assembled product have quality problems. Summary of the Utility Model

[0028] Figure 2 It is an exploded view of an embodiment of an assembly jig for an automotive center air duct provided by an embodiment of the present utility model;

[0029] Figure 3 It is a schematic structural diagram of an elastic support rod in an embodiment of an assembly jig for an automotive center air duct provided by an embodiment of the present utility model. Detailed Embodiments

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0031] As Figures 1-3 shown, an assembly jig for an automotive center air duct, wherein:

[0032] A first frame body 6;

[0033] A first plastic part accommodating carrier 1, disposed on the first frame body 6,

[0034] A pressing plate 2, oppositely disposed to the first plastic part accommodating carrier 1, and an elastic support rod 21 is disposed on the first plastic part accommodating carrier 1;

[0035] A guide post 3, disposed on the first frame body 6, and the pressing plate 2 is movably sleeved on the guide post 3 and moves along the vertical direction of the guide post 3;

[0036] A driving device 4, fixedly connected to the pressing plate 2, for applying a force to the pressing plate 2 to cause a second plastic part to move along the guide post 3 towards the first plastic part accommodating carrier 1.

[0037] In the actual application process, it can be understood that the first plastic part accommodating carrier 1 is the bottom plate, the pressing plate 2 is the cover plate. Place the plastic product on the bottom plate, the elastic support rod on the cover plate contacts the plastic product, and then perform a downward pressing operation on the pressing plate 2 so that the elastic support rod on the pressing plate 2 contacts the buckle on the plastic product. Continue to apply pressure to the pressing plate 2. At this time, the elastic support rod on the pressing plate 2 deforms until the elastic support rod is compressed. At this time, the elastic support rod is directly in abutting connection with the buckle or lock on the plastic product, and the rest of the plastic product is in a non-pressed state. Continue to apply pressure to the pressing plate 2. At this time, due to the rigid connection between the elastic support rod and the buckle or lock on the plastic product, the pressure is transmitted to the buckle or lock, and the buckle or lock deforms due to the acting force to complete the locking operation.

[0038] In the above solution, the elastic deformation of the elastic support rod is used to eliminate the deformation formed when the plastic product is pressed, which is convenient for the press-fitting treatment of the plastic product and greatly improves the accuracy of press-fitting.

[0039] As a further preferred implementation, in the above-mentioned assembly fixture for the central air duct of an automobile, wherein: the elastic support rod 21 includes a guide sleeve fixing plate 211, a spring 212 is arranged in the guide sleeve fixing plate 211, and a guide sleeve 213 inserted into the guide sleeve fixing plate 211 and in contact connection with the spring 212, and a press-fitting profiling 214 is inserted into the guide sleeve 213.

[0040] During actual application, the press-fitting profiling 214 directly contacts the plastic product. The pressure applied to the first plastic part accommodating carrier 1 is accurately applied to the buckle or lock through the press-fitting profiling 214.

[0041] As a further preferred implementation, in the above-mentioned assembly fixture for the central air duct of an automobile, wherein: an anti-rotation locking pin 215 is further arranged on the guide sleeve fixing plate 211, and anti-rotation holes 216 matching the anti-rotation locking pin 215 are respectively arranged at the end parts of the guide sleeve and the press-fitting profiling 214.

[0042] By arranging the anti-rotation locking pin 215, the guide sleeve and the press-fitting profiling 214 are fixed by the anti-rotation locking pin 215, so as to prevent the press-fitting profiling 214 from rotating under pressure and thus affecting the press-fitting effect.

[0043] As a further preferred implementation, in the above-mentioned assembly fixture for the central air duct of an automobile, wherein: a pressure regulator is further included, and the pressure regulator is arranged in the guide sleeve fixing plate 211 and contacts the spring 212.

[0044] As a further preferred implementation, in the above-mentioned assembly fixture for the central air duct of an automobile, wherein: the pressure regulator is formed by a nut 217, and a thread matching the nut 217 is arranged in the guide sleeve fixing plate 211.

[0045] The nut 217 is intended to adjust the movement and deformation distance of the spring 212. The closer the bottom of the thread is to the spring 212, the smaller the movement and deformation distance of the spring 212, and vice versa, the larger the movement and deformation distance of the spring 212.

[0046] As a further preferred implementation, the above-mentioned assembly fixture for the central air duct of an automobile is characterized in that it further includes a side pressing device 5, which is arranged at both ends or around the first plastic part accommodating carrier 1. When the upper and lower die plastic parts of the central air duct of the automobile are placed on the first plastic part accommodating carrier 1, the upper and lower die plastic parts of the central air duct of the automobile are assisted and fixed by the side pressing devices at both ends. At the same time, when the pressing plate 2 applies pressure to the upper and lower die plastic parts of the central air duct of the automobile, the upper and lower die plastic parts of the central air duct of the automobile are prevented from being displaced left and right due to pressure, and the pressing efficiency is further improved.

[0047] As a further preferred embodiment, for the above-mentioned assembly jig for an automotive center air duct, the driving device 4 includes a first driving fixing plate 41. At the upper end of the first driving fixing plate 41, there is a first driver 42 and a driving rod 43 connected to the first driver 42. The hydraulic driving rod 43 passes through the first driving fixing plate 41 and is connected to the pressing plate 2.

[0048] As a further preferred embodiment, for the above-mentioned assembly jig for an automotive center air duct, the driving device 4 further includes a second driver 44, and the second driver 44 is connected to the driving rod 43.

[0049] Because there are many snap positions on the upper and lower plastic parts of the center air duct, the force applied by the first driver is dispersed. If a single pressure application is used, the assembly may not be in place due to insufficient applied force. To ensure proper assembly, after the first pressure application is completed, a second pressure application by the second driver is carried out to ensure that there is sufficient pressure to assemble the snap positions in place.

[0050] As a further preferred embodiment, for the above-mentioned assembly jig for an automotive center air duct, it further includes a second frame body 7. The second frame body 7 is arranged at the lower end of the first frame body 6 to adjust the height of the first frame body 6 so that the height of the first frame body 6 conforms to ergonomics, facilitating the operator to place the plastic parts of the automotive center air duct.

[0051] As a further preferred embodiment, for the above-mentioned assembly jig for an automotive center air duct, it further includes sliding wheels, which are arranged at the bottom of the second frame body 7 and are used to facilitate the movement of the assembly jig for the automotive center air duct.

[0052] List a specific implementation and application method:

[0053] The operator first places the upper and lower plastic parts of the center air duct on the lower first plastic part accommodating carrier 1 at the same time, and uses the side pressing device to assist in fixing the upper and lower plastic parts of the center air duct. The first driver 42 applies a driving force to the driving rod 43 so that the driving rod 43 drives the pressing plate 2 to move along the guiding column 3 towards the second plastic part. When the elastic support rod on the pressing plate 2 contacts the upper and lower plastic parts of the center air duct, the first driver 42 stops working. At this time, the second driver 44 continues to apply a force to the driving rod 43 so that the elastic support rod on the pressing plate 2 applies a force to the snap points on the upper and lower plastic parts of the center air duct to achieve snapping. At this time, the automatic assembly of the center air duct components is completed.

[0054] Because there are many plastic part buckle positions on the upper and lower parts of the central air duct, the force applied to the upper part will be dispersed. If a single pressure application is used, the assembly may not be in place due to insufficient pressure. To ensure proper assembly, after the first pressure application, a second pressure application was carried out to ensure that there is enough pressure to assemble the buckle positions in place.

[0055] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
