Description

Technical Field

[0001] This utility model relates to the field of automotive design and manufacturing technology, and in particular to a support fixture for the tailgate of an automotive front-end processing vehicle. Background Technology

[0002] Currently, before the microcar body enters the pretreatment electrophoresis, a buffer pad is installed on each side of the tailgate to prevent the tailgate from closing. This method makes the tailgate less prone to deformation, but it is costly. The buffer pad is made of rubber and deforms after being baked at high temperature, so it cannot be reused. In addition, the electrophoretic paint film at the installation location of the buffer pad is uneven, and it is an exposed surface after painting, which affects the appearance. Now, most microcars are supported by corresponding support fixtures to replace the buffer pad.

[0003] However, the current automotive front-end tailgate support fixtures have the following problems when in use: In order to improve stability, most fixtures will add corresponding stabilizing structures. However, traditional fixture stabilizing structures are mostly welded and fixed to the bracket. If a component of the stabilizing structure of the fixture is damaged, the entire fixture will need to be replaced, resulting in high usage costs. Utility Model Content

[0004] The purpose of this utility model is to provide a support fixture for the tailgate of an automotive front-end processing vehicle. It aims to solve the problem that existing automotive front-end processing tailgate support fixtures often add corresponding stabilizing structures to improve stability. However, traditional fixture stabilizing structures are mostly welded and fixed to the bracket. If a component of the stabilizing structure of the fixture is damaged, the entire fixture needs to be replaced, resulting in high usage costs.

[0005] To achieve the above objectives, this utility model provides a support fixture for the tailgate of an automobile front-end processing vehicle, including a base. The base is symmetrically provided with non-through T-shaped mounting grooves, and a limiting mechanism is provided on the sliding side of the T-shaped mounting grooves. A first bracket is detachably installed on the top of the base.

[0006] The first bracket is limited by the limiting mechanism, and a second bracket is provided at the top. A first cylinder and a second cylinder are welded to the rear side of the first bracket respectively. The first cylinder has a through cross cavity inside, and the second cylinder has a circular through cavity inside.

[0007] It also includes stabilizing institutions;

[0008] The stabilizing mechanism includes a T-shaped column, a threaded cylinder, a threaded tie rod, a fixed base, a connecting column, and a support device. The T-shaped column is detachably connected to the first cylinder. The threaded cylinder is integrally mounted on the T-shaped column. The threaded tie rod passes through the second cylinder and is threadedly connected to the threaded cylinder. The connecting column is integrally mounted on the fixed base and is detachably connected to the first bracket. The support device is detachably mounted on the side of the second bracket near the connecting column.

[0009] The first support also has a stabilizing crossbar at the top.

[0010] The first bracket also has a curved section on one side of its top.

[0011] The support device includes a threaded disc and a support rod. The threaded disc is threadedly connected to the support rod and is symmetrically arranged on both ends of the support rod. It is detachably connected to the connecting column and the second bracket, respectively.

[0012] The threaded tie rod is fitted with a rubber sleeve on its outer side, and the rubber sleeve can move between the threaded cylinder and the second cylinder.

[0013] This utility model discloses a car front-end tailgate support fixture. The T-shaped block at the bottom of the first bracket directly mates with the T-shaped groove on the base for installation. Finally, it is limited by a limiting mechanism. The structure of the T-shaped column, threaded cylinder, threaded tie rod, fixed seat, connecting column and support device directly forms a detachable stable support structure between the first bracket and between the first bracket and the second bracket. While improving the stability of the first bracket and the second bracket, the entire fixture does not need to be replaced if the corresponding parts are damaged. This solves the problem that existing car front-end tailgate support fixtures often add corresponding stabilizing structures to improve stability, but traditional fixture stabilizing structures are mostly welded and fixed to the bracket. If a component of the stabilizing structure is damaged, the entire fixture needs to be replaced, resulting in high usage costs. Attached Figure Description

Detailed Implementation

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Example 1: As Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of the automotive front-end processing tailgate support fixture. Figure 2 This is a structural schematic diagram of the fixed base 110. Figure 3 This is a structural schematic diagram of the T-shaped column 107. This utility model provides a support fixture for an automotive front-end processing tailgate: it includes a base 101, a first bracket 103, a second bracket 104, a first cylinder 105, a second cylinder 106, and a stabilizing mechanism. The stabilizing mechanism includes the T-shaped column 107, a threaded cylinder 108, a threaded tie rod 109, a fixed seat 110, a connecting column 111, and a supporting device. The supporting device includes a threaded disc 114 and a supporting rod 115. This solution addresses the problem that existing automotive front-end processing tailgate support fixtures often add stabilizing structures to improve stability. However, traditional fixture stabilizing structures are mostly welded to the brackets, requiring replacement of the entire fixture when a component of one stabilizing structure fails, resulting in high costs. The aforementioned solution allows for the individual replacement of the fixture's stabilizing support structure.

[0022] In this embodiment, the base 101 is provided with a connecting part that cooperates with the vehicle frame.

[0023] The base 101 has symmetrically arranged non-through T-shaped mounting slots. A limiting mechanism 102 is provided on the sliding side of the T-shaped mounting slots. A first bracket 103 is detachably installed on the top of the base 101. The T-shaped mounting slots can directly cooperate with the symmetrically arranged T-shaped blocks at the bottom of the first bracket 103, thereby enabling the quick installation and removal of the first bracket 103. The limiting mechanism 102 includes a T-shaped abutment block and a fixing plate. The fixing plate has symmetrically integrated T-shaped abutment blocks that can cooperate with the T-shaped mounting slots and abut against the first bracket 103 for limiting. The fixing plate is fixed by bolts.

[0024] The first bracket 103 is limited by the limiting mechanism 102, and a second bracket 104 is provided at the top. A first cylinder 105 and a second cylinder 106 are welded to the rear side of the first bracket 103, respectively. The first cylinder 105 has a through-hole cross cavity, and the second cylinder 106 has a circular through cavity. The two connecting ends of the second bracket 104 can be connected to the first bracket 103 by welding or bolting. The cross cavity inside the first cylinder 105 is used to prevent the T-shaped column 107 from rotating after installation.

[0025] The T-shaped post 107 is detachably connected to the first cylinder 105. The threaded cylinder 108 is integrally mounted on the T-shaped post 107. The threaded pull rod 109 passes through the second cylinder 106 and is threadedly connected to the threaded cylinder 108. The connecting post 111 is integrally mounted on the fixing seat 110 and is detachably connected to the first bracket 103. The support device is detachably mounted on the second bracket 104 near the connecting post 111. A cross-shaped protrusion is provided on one side of the limiting disc of the T-shaped post 107 for engaging with the cross cavity of the first cylinder 105 for installation. The threaded cylinder 108 is directly integrally mounted on one side of the T-shaped post 107 and can engage with the threaded pull rod 109, thereby directly forming a stable structure on the first bracket 103 to improve the stability of the first bracket 103. The threaded cylinder 108 can be removed by simply unscrewing the threaded pull rod 109. The fixing seat 110 is fixed to the first bracket 103 by bolts.

[0026] Secondly, a stabilizing crossbar 112 is also provided at the top of the first support 103. The stabilizing crossbar 112 is an integral structure with the first support 103 and its function is to improve the stability of its top support arm.

[0027] Then, a curved portion 113 is also provided on one end of the top of the first bracket 103. The curved portion 113 is used for support.

[0028] Finally, the threaded disc 114 is threadedly connected to the support rod 115 and symmetrically arranged on both ends of the support rod 115, and is detachably connected to the connecting column 111 and the second bracket 104 respectively. The threaded disc 114 is provided with a non-through threaded hole, which is directly used for installation on the stepped external thread ends on both sides of the support rod 115. After the threaded disc 114 is installed on the support rod 115, it forms an I-shaped support structure. Then, it is placed between the connecting column 111 and the second bracket 104, and the threaded discs 114 on both sides are connected to the short cylinders on the connecting column 111 and the second bracket 104 respectively by bolts, thus forming a detachable structure that provides stable support for the second bracket 104.

[0029] To improve stability, existing automotive front-end processing tailgate support fixtures often incorporate stabilizing structures. However, traditional fixture stabilizing structures are typically welded to brackets, requiring replacement of the entire fixture if a component fails, resulting in high costs. This invention addresses this issue by first mounting the fixture onto the vehicle frame via the base 101. Then, the first bracket 103 and the second bracket 104 cooperate with the tailgate for support, preventing the tailgate from closing during processing. The T-shaped block at the bottom of the first bracket 103 directly engages with the T-shaped groove on the base 101 for installation. Finally, the limiting mechanism 102 limits the movement; removing the limiting mechanism 102 allows the first bracket 103 to be disassembled from the base 101. The T-shaped post 107 and the threaded cylinder 108... The threaded tie rod 109, the fixed seat 110, the connecting column 111, and the support device directly form detachable stable support structures between the first bracket 103 and between the first bracket 103 and the second bracket 104. While improving the stability of the first bracket 103 and the second bracket 104, the threaded tie rod 109, the threaded cylinder 108, the support rod 115, and the threaded disc 114 can be directly replaced without replacing the entire tooling if the corresponding components are damaged. This solves the problem that existing automotive front-end tailgate support tooling often adds corresponding stabilizing structures to improve stability, but traditional tooling stabilizing structures are mostly welded and fixed to the bracket. If a component of the stabilizing structure of the tooling is damaged, the entire tooling needs to be replaced, resulting in high usage costs.

[0030] Example 2: Figure 4 As shown, where Figure 4 This is a schematic diagram of the overall structure of the automotive front-end processing tailgate support fixture. Based on the first embodiment, this utility model provides an automotive front-end processing tailgate support fixture. A rubber sleeve 201 is sleeved on the outer side of the threaded pull rod 109. The rubber sleeve 201 can move between the threaded cylinder 108 and the second cylinder 106.

[0031] In this embodiment, the rubber sleeve 201 provided on the outside of the threaded pull rod 109 can provide a certain degree of safety protection for its external thread end. At the same time, the rubber sleeve 201 can directly pass through the second cylinder 106, but its diameter is smaller than the limiting disk of the threaded pull rod 109 and larger than the diameter of its thread end. There is a gap between the end of the threaded pull rod 109 near the limiting disk and the limiting disk. In actual use, there may be corresponding full-thread or half-threaded rods for temporary replacement. Therefore, when the threaded pull rod 109 adopts a half-threaded rod, that is, when its thread end is completely inside the threaded cylinder 108 after installation, the rubber sleeve 201 is not required because there is no exposed thread structure.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
