Description

Technical Field

[0001] The utility model relates to the technical field of automobile design and manufacture, and more specifically to a vehicle body slide automatic avoidance locking pin device. Background Art

[0002] The skid with conventional skid support and locking mechanism has interference with the body sheet metal structure when introducing new models due to the restriction of the body structure. The pins cannot be avoided (the Z direction of the body sheet metal structure cannot be optimized or opened to avoid), which makes it impossible for the new model to be assembled normally. The skid support and locking structure must be modified to be removable or foldable. This structural support cannot be equipped with a locking mechanism, resulting in the loss of the skid locking function, which causes the risk of the body falling off the skid and falling into the slot during the pre-treatment electrophoresis production process. When producing new models, the skid must be adaptively modified to remove or fold the interfering support structure to solve the problem of interference with the body sheet metal structure. In this case, the skid modification cost and the human resources for the conversion of the skid support structure due to the model switching must be increased, which increases the operating cost and efficiency of the production system.

[0028] Example 1

[0029] like Figure 1-9As shown, the automatic avoidance locking pin device of the vehicle body skid of this embodiment includes a main sleeve 1, a main sleeve connecting rib plate 2, a skid leg connecting back plate 3, an anti-rotation retaining spring 4, an eccentric pin 5, an eccentric sleeve 6, a rotating sleeve 8, a main sleeve plug cover 9 and a rotating handle 10. The main sleeve connecting rib plates 2 are two and are vertically welded to the main sleeve 1 along the side wall of the main sleeve 1. The two main sleeve connecting rib plates 2 are symmetrically arranged relative to the central axis of the main sleeve 1. The skid leg connecting back plate 3 is welded and fixed to the two main sleeve connecting rib plates 2. The anti-rotation retaining spring 4 is a U-shaped structure, and the two sides of the U-shaped structure cooperate with the two sides of the rotating handle 10. The anti-rotation retaining spring 4 is welded to the skid leg connecting back plate 3, and the anti-rotation retaining spring 4 can be two parallel ones, but the embodiment is certainly not limited to this. After the eccentric pin 5 is assembled with the eccentric sleeve 6, it is installed into the main sleeve 1 along the slideway 11 above the inner wall of the main sleeve 1. After the spring 7 is installed on the rotating sleeve 8, it is installed into the main sleeve from the bottom of the inner wall of the main sleeve 1. The eccentric pin 5 is connected with the rotating sleeve 8 through a spline. The main sleeve plug cover 9 is connected with the bottom of the main sleeve 1 by bolts, and then the eccentric pin 5, eccentric sleeve 6, spring 7 and rotating sleeve 8 are encapsulated in the main sleeve 1, and the lower end of the rotating sleeve 8 extends out of the main sleeve plug cover 9; the rotating handle 10 is connected to the lower end of the rotating sleeve 8 by welding or threaded and bayonet connection. In order to facilitate the maintenance and replacement of components, the threaded bayonet connection is preferably used. The skid leg connection back plate 3 is connected to the skid support leg matching structure by bolts so that it can be assembled to the vehicle body skid.

[0030] When the skid assembly body and the device of this embodiment do not interfere with each other, the eccentric pin 5 and the upper part of the eccentric sleeve 6 can be extended into the locking hole of the skid assembly body. After the body and the skid are assembled normally, at the body skid locking station of the production line, the rotating handle 10 is turned by a mechanical device, and the rotating handle 10 drives the rotating sleeve 8 and the eccentric pin 5 to rotate 180 degrees to achieve locking of the body (the unlocking process is completed at the unlocking station of the production line, and the locking is reversed, that is, the rotating handle is turned in the opposite direction).

[0031] When the locking pin interferes with the body structure of the imported vehicle, the eccentric pin 5 that is interfered with, under the force of the vehicle body's own weight, the eccentric pin 5, the eccentric sleeve 6 and the spring 7 move downward and retract into the main sleeve 1, thereby completing automatic avoidance, so that the vehicle body and the skid can be pried together normally; when the pressure of the vehicle body is removed, the eccentric pin 5 and the eccentric sleeve 6 automatically recover under the elastic force of the spring 7, thereby completing a working stroke of automatic avoidance. This device realizes the locking and unlocking functions of the vehicle body through the rotating eccentric pin 5, and the rotating handle 10 is turned by a mechanical device (rotated 180 degrees clockwise or counterclockwise), and the rotating handle 10 drives the rotating sleeve 8 and the eccentric pin 5 to rotate 180 degrees to achieve locking ( Figure 2 ) and unlock( Figure 1 ) to lock and unlock the vehicle body.

[0032] This embodiment improves the traditional eccentric locking mechanism of the vehicle body, adds an eccentric sleeve 6, a spring 7, a rotating sleeve 8, and adds an eccentric sleeve slideway 11 to the main sleeve 1, and decomposes the locking eccentric pin into two sections, a rotating sleeve 8 connected by a spline pair and an eccentric pin 5 matched therewith, and adds a spring 7 component in the middle; finally, the improved components are encapsulated in the main sleeve 01 by the main sleeve plug cover 9; thereby, the eccentric pin 5 can be pressed into the main sleeve 01 under the situation of external force applied to avoid interference during the prying process; and when no external force is applied, normal prying body locking and unlocking functions can be achieved.

[0033] When the body structure of the newly developed vehicle interferes with the body skid support locking pin structure (the interference amount is less than or equal to 27mm, that is, Figure 1 When the h in the figure is less than or equal to 27 mm in a normal state, the automatic avoidance locking pin device of the utility model can be used to realize the normal assembly of the vehicle body without switching the support or conversion of the slide.

[0034] The automatic locking pin avoidance device of the body slide of the present embodiment improves the matching selection of new product models and the slide and optimizes the body structure of the slide support locking hole, increases the freedom of new product structure development, shortens the cycle time of new model production introduction, saves tooling modification costs, improves production line operation efficiency, saves the additional labor cost of converting the slide support structure, and reduces production operation costs.
