The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.
[0030] See also Figures 1 to 4 The present application provides a car rear cover tooling, which is used to limit the opening angle of the car rear cover 100 relative to the car body. The car rear cover tooling includes a main body 10, a car body mounting member 20, a rear cover limiting member 30 and a rear cover clamping member 40. Among them, along the axial direction of the main body 10, the main body 10 has a first end 11 and a second end 12 that are relatively arranged. The car body mounting member 20 is arranged on the first end 11 of the main body 10, and is used to be connected to the car body. The rear cover limiting member 30 is arranged on the second end 12 of the main body 10, and the rear cover clamping member 40 is arranged on the rear cover limiting member 30, and is used to be connected to the car rear cover 100. Therefore, the car rear cover 100 can be opened to a certain angle relative to the car body under the support of the main body 10, and the tooling is firmly fixed after installation, and the car will not fall abnormally even if it is turned 360°, ensuring that the car rear cover 100 will not be opened abnormally. The rear cover 100 of the automobile is limited to the opening angle by the tooling, and the opening angle is reasonable, which will not cause quality problems such as poor electrophoresis and poor drainage, and effectively ensure the paint quality of the rear cover 100 of the automobile. In this embodiment, the length of the body 10 is set to 152mm. Through multiple verifications, the rear cover opening angle is used with a connecting rod of this length, and there is no problem of poor electrophoresis and poor drainage.
[0031] Specifically, a limiting gap 50 is provided between the rear cover limiting member 30 and the rear cover clamping member 40, and the limiting gap 50 is used for clamping with the rear cover 100 of the automobile. The clamping method is used to realize the fixed connection between the tooling and the rear cover 100 of the automobile, simplifying the installation process of the tooling, shortening the installation and removal time, and being easy to operate, meeting the company's production rhythm and improving production efficiency. In addition, this method also greatly simplifies the structure of the tooling, which is simple in structure, compact and light, and easy to store and operate.
[0032] Further, the width of the rear cover clamping member 40 is set to D, and the length of the rear cover clamping member 40 is set to L. The rear cover 100 of the automobile is provided with a lock hole 101, and the diameter of the lock hole 101 is set to R1. In this embodiment, D and R1 satisfy the relationship: D<R1, and L and R1 satisfy the relationship: L>R1. Under this structure, the rear cover clamping member 40 can pass through the lock hole 101 and extend into the inner side of the rear cover 100 of the automobile, and abut against the inner side of the rear cover 100 of the automobile, the side wall of the lock hole 101 is inserted into the limiting gap 50, and the rear cover limiting member 30 abuts on the outer side of the rear cover 100 of the automobile. A firm connection with the rear cover 100 of the automobile is achieved, and even if the automobile is turned 360°, the rear cover clamping member 40 and the rear cover limiting member 30 will not be detached from the rear cover 100 of the automobile, and the connection is firm. And there is no need to use screws, bolts and other connecting parts, and a simple clamping method is used to achieve a firm connection, with a simple structure and easy installation and operation.
[0033] Preferably, the axis of the rear cover limiter 30 is perpendicular to the axis of the rear cover clamping member 40, so that after the rear cover clamping member 40 passes through the lock hole 101 and extends into the inner side of the rear cover 100 of the automobile, it can be vertically pressed against the inner side of the rear cover 100 of the automobile, and the abutment is more firm.
[0034] Preferably, the length L of the rear cover clamping member 40 is set to 21 mm, and the width D is set to 5 mm. The rear cover clamping member 40 can be firmly clamped on the inner side of the rear cover 100 of the automobile to prevent the rear cover 100 of the automobile from falling off.
[0035] Furthermore, along the axial direction of the body 10, the height of the limit gap 50 is set to H, and the condition is satisfied: 2mm≥H≥0.7mm. H can be 0.7mm, 1mm, 1.3mm, 1.6mm, 2mm, etc. In this embodiment, the preferred value is 1mm, that is, the height H of the limit gap 50 = 1mm. Since the thickness of the rear cover 100 of the automobile is usually 0.7mm, the limit gap 50 is slightly larger than the thickness of the rear cover 100 of the automobile within this value range, which can ensure the clamping of the rear cover 100 of the automobile while achieving the convenience of installation.
[0036] Furthermore, the structure of the rear cover limiter 30 can be a frustum, a cylinder, a square or the like. In the present embodiment, the rear cover limiter 30 is a frustum, the top surface of which is connected to the rear cover clamping member 40 , and the bottom surface is connected to the body 10 .
[0037] Specifically, a connection portion 31 is provided on the end surface of the rear cover stopper 30 near the rear cover clamping member 40, and the rear cover clamping member 40 is connected to the connection portion 31. A limiting gap 50 is formed by the side wall of the connection portion 31, the side wall of the rear cover clamping member 40, and the end surface of the rear cover stopper 30. Of course, it is not limited to this. In other embodiments, the above-mentioned limiting gap 50 can also be formed by directly slotting the rear cover stopper 30 or the rear cover clamping member 40. The rear cover clamping member 40 and the connection portion 31 are fixedly connected by welding.
[0038] Furthermore, the cross-section of the connecting portion 31 is circular, and the diameter of the connecting portion 31 is set to R2. R1 and R2 satisfy the relationship: R1<R2. During installation, the connecting portion 31 can be snapped into the lock hole 101, and because the diameter of the connecting portion 31 is larger than the diameter of the lock hole 101, the connecting portion 31 and the lock hole 101 are interference fit, which further increases the firmness of the connection. It is ensured that the tooling is firmly connected to the rear cover 100 of the car only by snapping, and that the tooling will not fall off the rear cover 100 of the car during the electrophoresis process of the car. In this embodiment, the data of R1 is 6.5mm and R2 is 7mm. Of course, the values of the two are not limited to this and can be set according to actual needs.
[0039] Specifically, the body mounting part 20 is provided with a bending part 21, and the bending part 21 is provided with a through hole 22. When installing the tooling, the through hole 22 is aligned with the process hole on the rear panel of the car, and the mounting bolts are screwed on to realize the connection between the body mounting part 20 and the rear panel of the car.
[0040] Preferably, the through hole 22 is configured as a strip hole, so that the connection position between the bolt and the through hole 22 can be fine-tuned, thereby enabling the angle at which the rear cover of the automobile is supported by the rear cover tooling to be fine-tuned, thus providing a wider range of applications.
[0041] By setting the bending portion, the installation position of the bolt avoids the position of the main body 10, and the installation operation is easier. In this embodiment, the bending angle of the bending portion 21 is 90°, and the structure is more solid. Of course, it is not limited to this. In other embodiments, the bending angle of the bending portion 21 can be selected according to actual needs.
[0042] In order to ensure the stability of the rear cover 100, two fixtures are installed on each car during installation, which are installed on both sides of the rear cover 100 to provide stable support for the rear cover and avoid deformation of the rear cover after electrophoresis. Of course, the number of fixtures is not limited to this and can be set according to actual needs, as long as the rear cover of the car is not deformed.
[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0044] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
