[0002] Automobile doors and hinges are usually positioned and assembled in the adjustment line of the welding shop. Existing production lines are usually single-model rigid lines or two-model flexible lines: for a single-model rigid line, the entire production line is dedicated to a single model and does not have the ability to switch models; two-model flexible lines usually adopt the form of an overhead track and a special fixture. By pulling out the fixture of the currently produced model through the track, other fixtures are left idle, and their switching requires a large amount of site space.

[0003] In a single-model rigid line, the structures are all dedicated to a single model, and it is difficult to transform when introducing a new model later; in a two-model flexible line, in the form of track pulling, its fixtures occupy a large amount of space and the overhead track structure is complex.

[0022] For the sake of description, spatial relative terms such as "above", "over", "on the upper surface", "above" can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device shown in the figure. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "over other devices or structures" will be positioned as "below other devices or structures" or "under other devices or structures" afterwards. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned or rotated in other different ways by 90 degrees or in other orientations, and corresponding explanations are made for the spatial relative descriptions used here.

[0023] The following describes in detail the specific implementation manners of the present invention in conjunction with the accompanying drawings and preferred embodiments.

[0024] As Figure 1 shown, a positioning mechanism for the installation of a flexible line hinge of an automobile includes an automatic body X-direction sliding mechanism 1, an automatic body Y-direction sliding mechanism 2, a manual body X / Y-direction sliding adjustment mechanism 3, a manual body Z-direction sliding adjustment mechanism 4, a panel positioning adjustment unit 5, and a manual operation platform 6. The automatic body Y-direction sliding mechanism is installed on the automatic body X-direction sliding mechanism. The manual body X / Y-direction sliding adjustment mechanism is installed on the automatic body Y-direction sliding mechanism. The manual body Z-direction sliding adjustment mechanism is installed on the manual body X / Y-direction sliding adjustment mechanism. The panel positioning adjustment unit is installed on the manual body Z-direction sliding adjustment mechanism.

[0025] As Figure 2 and Figure 3 shown, the automatic body X-direction sliding mechanism includes a base 1.1, a servo motor 1.2, a ball screw 1.3, a first linear guide 1.4, and an X-direction slide base plate 1.5. The servo motor and the ball screw are fixed to the base through a support. The first linear guide is fixed to the base. The ball screw slider and the first linear guide slider are connected to the X-direction slide base plate. The servo motor controls the slide to move to a specified position to match the X-direction position of the body conveyed to this station by the roller bed.

[0026] As Figure 4 shown, the automatic body Y-direction sliding mechanism includes a guide rail base 2.1, an electric control cylinder 2.2, a second linear guide 2.3, a slide limit component 2.4, a Y-direction slide base plate 2.5, and a slide drag chain 2.6. The guide rail base is fixed on the X-direction slide base plate. The second linear guide is fixed on the guide rail base. The electric control cylinder is fixed on the X-direction slide base plate. The piston rod of the electric control cylinder is connected to the Y-direction slide base plate. The adjustment of the mechanism in the Y-direction of the body is controlled by the electric control cylinder.

[0027] As Figure 5As shown in the figure, the manual X / Y-direction sliding adjustment mechanism for the vehicle body is installed on the Y-direction slide base plate. The manual X / Y-direction sliding adjustment mechanism for the vehicle body includes a third guide rail base plate 3.1, a third linear guide rail 3.2, a first limit component 3.3, a Y-direction base plate 3.4, a fourth guide rail base plate 3.5, a fourth linear guide rail 3.6, a second limit component 3.7, and an X-direction base plate 3.8. The third guide rail base plate is fixed on the Y-direction slide base plate. The third linear guide rail is fixed on the third guide rail base plate. The bottom of the Y-direction base plate is slidably connected to the third guide rail. The manual adjustment distance in the Y direction is controlled by the first limit component 3.3, and the adjustable distance is 5 mm. The fourth guide rail base plate is fixed on the Y-direction base plate. The fourth linear guide rail is installed on the fourth guide rail base plate. The X-direction base plate is slidably matched with the fourth guide rail base plate. The first limit component is fixed on both sides of the Y-direction base plate. The second limit component is fixed on both sides of the X-direction base plate. The manual adjustment distance in the X direction is controlled by the second limit component 3.7, and the adjustable distance is 5 mm. This mechanism has no power equipment and is mainly used for manual small-stroke sliding of the vehicle body in the X and Y directions.

[0028] Figure 6 As shown in the figure, the manual Z-direction sliding adjustment mechanism for the vehicle body includes a unit support 4.1, a fourth linear guide rail 4.2, a Z-direction slide base plate 4.3, a counterweight guide wheel 4.4, a counterweight 4.5, a Z-direction cylinder 4.6, a pressure regulating valve 4.7, and a buffer 4.8. The bottom of the unit support is fixed on the X-direction base plate. The counterweight is installed inside the unit support. The counterweight guide wheel is installed on the top of the unit support. The fourth linear guide rail is fixed on the side of the unit support. The Z-direction slide base plate is slidably connected to the fourth linear guide rail. The upper part of the Z-direction slide base plate is connected to the counterweight through a cable bypassing the counterweight guide wheel. The buffer is installed on the upper part of the unit support and cooperates with the top of the Z-direction slide base plate. The Z-direction cylinder is installed at the lower part of the unit support, and the piston rod of the Z-direction cylinder is connected to the lower part of the Z-direction slide base plate. The overall counterweight of the above mechanism is completed by increasing or decreasing the weight of the counterweight block inside the unit support. At the same time, the operator can control the displacement adjustment of the entire slide mechanism by adjusting the pressure regulating valve.

[0029] As Figure 7As shown in the figure, the plate positioning and adjusting unit includes a first clamping unit 5.1, a main positioning pin unit 5.2, and a second clamping unit 5.3. The first clamping unit, the main positioning pin unit, and the second clamping unit are sequentially fixed on the Z-direction slide base plate. Since the first clamping unit 5.1, the main positioning pin unit 5.2, and the second clamping unit 5.3 are all structures with common cylinders driving clamping blocks and can be adjusted according to the corresponding vehicle models, they will not be elaborated here. By matching the positioning pins of the second positioning unit 5.2 with the body positioning holes (with the help of the manual adjustment amount of the mechanism), and clamping by the first positioning unit 5.1 and the third positioning unit 5.3, the accurate positioning of the hinge on the body by the mechanism can be achieved.

[0030] As Figure 8 shown in the figure, the manual operation platform includes manual operation platform legs 6.1, a manual operation platform surface 6.2, and a platform guardrail 6.3. The bottom of the manual operation platform surface is fixed on the X-direction slide base plate through the manual operation platform legs. A number of working holes are provided on the manual operation platform surface, and a platform guardrail is provided around the working holes. The body Z-direction manual sliding adjustment mechanism passes through the working holes. There are four working holes in this device, so four corresponding mechanisms can be placed.

[0031] This mechanism can implement the ability to reserve the introduction of four vehicle models, realize the co-line production of four vehicle models, save the floor area of the production line, and largely solve the needs of the host factory for the increase of listed vehicle models and the shortage of production land in the workshop. At the same time, the mechanism is simplified, with a large reach range for the XYZ directions of the body, and also takes into account the small-stroke adjustment during operation by personnel, solving problems such as ergonomics and improving the positioning accuracy of the equipment. In particular, the use of a counterweight and a cylinder speed control valve together greatly improves the operation accuracy and operability of personnel.

[0032] It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
