Description

Car embedded door handle assembly fixture

Technical Field

The utility model relates to a car embedded door handle assembly technology, in particular to a car embedded door handle assembly tool.

Background

The car embedded door handle refers to a car door handle with a door handle outer decoration bottom plate embedded into a through hole reserved in a sheet metal outside a car door from the inner side of the door. In general, a car door handle is mounted from the inside of a door, and when the car door handle and a lock body are mounted, the door handle and the lock body are required to be mounted in through holes reserved in inner sheet metal and outer sheet metal of the car door and in a space between the door handle and the outer sheet metal, and the outer edge of the door handle is required to be completely flush with the outer side face of the outer sheet metal of the car door. In order to prevent rainwater and dust from entering, the tightness between the door handle and the outer sheet metal of the door is ensured, and a rubber gasket with a convex cross section is further arranged between the edge of the door handle and the inner side surface of the outer sheet metal of the door. In order to ensure effective sealing of the rubber gasket, after the embedded door handle is placed at the mounting position, a certain pressure needs to be applied between the door handle and the outer sheet metal of the door before the door handle is fastened by bolts, so that the rubber gasket is in a reasonably compressed state, and the outer edge of the door handle is ensured to be completely flush with the outer side face of the outer sheet metal of the door. The prior art car embedded door handle assembly method adopts manual pressure, namely an operator pushes the whole door handle outwards, so that the pressure between the door handle and the sheet metal outside the car door is formed. Due to manual operation, the applied pressure is extremely uneven on the outer edge of the entire door handle, so that after the door handle is fastened, a part of the outer edge section of the door handle is higher than the outer surface of the door outer panel (which is generally referred to as "stepped-in"), or a part of the outer edge section of the door handle is lower than the outer surface of the door outer panel (which is generally referred to as "stepped-in"). According to the related art requirements, the occurrence of either "out" or "in" is not allowed, requiring re-work. Obviously, the assembly method of the embedded door handle of the car in the prior art has the problems of high labor intensity, difficulty in ensuring the assembly quality and the like.

According to the assembly process of the car embedded door handle, in order to ensure effective sealing of the rubber gasket, after the embedded door handle is placed at the installation position, a certain pressure needs to be applied between the door handle and the outer sheet metal of the car door before the door handle is fastened by bolts, so that the rubber gasket is in a reasonable compression state, and the outer edge of the door handle is completely flush with the outer side face of the outer sheet metal of the car door. The basic purpose of the assembly fixture for the embedded door handle of the car is to apply certain pressure between the door handle and the outer sheet metal of the car door and ensure that the outer edge of the door handle is completely flush with the outer side surface of the outer sheet metal of the car door. When the automobile embedded door handle assembly fixture is particularly used, after the embedded door handle is placed at the installation position, the push plate of the automobile embedded door handle assembly fixture is attached to the back surface of the embedded door handle, the positioning hook at the rear end of the push rod is inserted into the bolt hole at the lower part of the sheet metal installation window in the automobile door, and meanwhile, the positioning plate is attached to the right side surface of the sheet metal installation window in the automobile door; at this time, the retaining plate should be just attached to the inner side of the sheet metal in the door. The handle I and the handle II of the clamp type four-bar mechanism are pinched inwards, the handle II pushes the triangular connecting rod to rotate clockwise under the action of the supporting rod, and the angle of contact between the triangular connecting rod and the cambered surface at the rear end of the supporting rod pushes the supporting rod to rotate along the hinging seat, so that the supporting plate moves in the direction deviating from the pushing plate. Because the retaining plate is attached to the inner side surface of the inner door sheet metal, the inner door sheet metal cannot be pushed, and the movement of the retaining plate actually pushes the push plate, namely the embedded door handle assembly is pushed to one side of the outer door sheet metal, so that a certain pressure is applied between the door handle and the outer door sheet metal. In fact, the inward clamping of the handles i and ii of the four bar mechanism of the pliers type, i.e. the tension is formed between the push plate and the abutment plate, which is hindered by the sheet metal inside the door, so that the tension is applied to the back of the door handle, thus exerting a certain pressure between the door handle and the sheet metal outside the door. Through the size and the promotion position of adjustment push pedal to and the promotion distance of butt board, can make the even and suitable size of pressure between door handle and the outer panel beating of door.

For convenient operation and use, as one of the preferred schemes, a tension spring is also arranged between the triangle connecting rod and the handle I, so that the rear ends of the handle I and the handle II are kept in an unfolding state. Therefore, before tension is not applied to the assembly tool of the car embedded door handle, the push plate and the abutting plate are in a relatively closed state, and the operation is convenient.

For the assembly of adaptation multiple model car embedded door handle, make things convenient for the adjustment of tensile between push pedal and the butt plate, as one of preferred scheme, still be provided with adjusting bolt in clamp type four bar linkage's handle I, adjusting bolt sets up in the I inside of handle, and the front end is connected with the articulated seat of bracing piece, and the rear end stretches out the I end of handle, and rotatory adjusting bolt can adjust the articulated seat of bracing piece in the position at the I middle part of handle. Through adjusting the position of the support rod hinge seat in the middle of the handle I, the clockwise rotation angle of the triangular connecting rod can be adjusted, namely the rotation angle of the supporting rod is adjusted, the unfolding degree of the push plate and the supporting plate is adjusted, and the tension is actually adjusted. The expansion degree of the push plate and the retaining plate can be suitable for assembling embedded door handles of cars of different models. And the adjustment of the tension can ensure that the pressure between the door handle and the sheet metal outside the door is uniform.

In order to prevent the car embedded door handle from loosening in the fastening process, as one of the preferable schemes, a self-locking buckle is further arranged in a handle II of the clamp type four-bar mechanism; the checkpost of auto-lock buckle is rectangular shape, sets up inside handle II, and the rear section exposes in handle II inboard. Therefore, the handle I and the handle II are in a self-locking state after being back pinched, and the pressure between the door handle and the metal plate outside the vehicle door is kept, so that the door handle cannot loosen in the fastening process.

In order to increase the friction and the stability of the surfaces of the plate, the resisting plate and the positioning plate, as one of the preferable schemes, the surfaces of the pushing plate, the resisting plate and the positioning plate are provided with plastic or nylon lining plates. The plastic or nylon lining plates are arranged on the surfaces of the push plate, the resisting plate and the positioning plate, so that the slipping phenomenon in the pressurizing process can be effectively prevented, and the contact stability of the surfaces of the push plate, the resisting plate and the positioning plate and the opposite surfaces is improved.

Obviously, the assembly fixture for the embedded door handle of the car has the beneficial technical effects that the door handle is firmly positioned to the set position through the fixture and then fastened, so that the assembly quality of the door handle is ensured.
