Description

Technical Field

[0001] The utility model relates to the technical field of automobile component welding, in particular to a rear wheel cover welding tool. Background Art

[0002] The rear wheel cover is one of the parts of the car. During the production process, the rear wheel cover needs to be welded. The rear wheel cover includes a large cover and a small cover. The large cover and the small cover need to be fixed by a clamp before welding. However, during the fixing process, in order to prevent the rear wheel cover from shifting due to vibration during the transportation process, it is necessary to use bolts to fix and install it. Using this method will consume more time in the process of installing and disassembling the rear wheel cover, resulting in reduced production efficiency. In addition, due to certain errors in the size and hole position of the rear wheel cover (although within the error range, the tightness of the bolts will also affect the installation position of the rear wheel cover), during the welding process, the errors will be superimposed and the welding quality of the rear wheel cover will be reduced. For this reason, we propose a rear wheel cover welding tool. Utility Model Content

[0026] As a preferred embodiment, the number of the clamping mechanisms is six, namely the first clamping mechanism 9, the second clamping mechanism 10, the third clamping mechanism 11, the fourth clamping mechanism 12, the fifth clamping mechanism 13 and the sixth clamping mechanism 14; the first clamping mechanism 9 and the second clamping mechanism 10 are arranged on the front end surface of the workbench 1, and are used to clamp the front end top surface of the rear wheel cover 2; the third clamping mechanism 11 and the fourth clamping mechanism 12 are arranged on the right end surface of the workbench 1, and the third clamping mechanism 11 is used to clamp the rear wheel cover 2.

[0027] As a preferred embodiment; the driving device 7 adopts a clamping cylinder, and the clamping part 8 adopts a connecting rod clamp; in the present application, the clamping cylinder and the connecting rod clamp are cylinders and integrated clamps produced by Shanghai Dexus Mechanical Automation Technology Co., Ltd.; it can be understood that under the drive of the clamping cylinder, the connecting rod clamp can be driven to flip and fix the rear wheel cover 2. This fixing method, combined with the setting of its quantity and position, can not only effectively fix the rear wheel cover 2, but also quickly realize clamping and loosening, reduce the time of installation and disassembly, and improve production efficiency.

[0028] As a preferred embodiment; the number of the positioning mechanisms is two, namely the first positioning mechanism 15 and the second positioning mechanism 16, and the first positioning mechanism 15 and the second positioning mechanism 16 are respectively arranged at the two ends of the rear wheel cover 2; the sensor 4 adopts a proximity switch; it can be understood that the setting of the first positioning mechanism 15 and the second positioning mechanism 16 can mainly effectively position the two ends of the rear wheel cover 2, and the positioning covers a large area. After the two places are positioned, not only the two sides of the rear wheel cover 2, but also the front side part of the rear wheel cover 2 can achieve a precise positioning effect.

[0029] As a preferred embodiment; the welding tool also includes auxiliary baffles, and the number of the auxiliary baffles is three, namely a first auxiliary baffle 17, a second auxiliary baffle 18 and a third auxiliary baffle 19; the first auxiliary baffle 17, the second auxiliary baffle 18 and the third auxiliary baffle 19 are respectively arranged at the front end, the right end and the left end of the rear wheel cover 2; the first auxiliary baffle 17, the second auxiliary baffle 18 and the third auxiliary baffle 19 are respectively abutted against the rear wheel cover 2; by providing the first auxiliary baffle 17, the second auxiliary baffle 18 and the third auxiliary baffle 19, the top surface of each auxiliary baffle is arranged to be outwardly expanded and inclined, so that the rear wheel cover 2 can quickly find the installation position along each auxiliary baffle (when installing, the rear wheel cover 2 can be placed in the installation position according to the positions of the three auxiliary baffles), thereby improving the installation efficiency. At the same time, after the rear wheel cover 2 is installed, each auxiliary baffle can support it, and the effect of auxiliary positioning is also achieved.

[0030] As a preferred embodiment; a support seat 20 and a support plate 1 are also provided on the rear end surface of the workbench 1, and a first positioning connection hole 22 and a second positioning connection hole 23 are respectively provided on the support seat 20 and the support plate 21; it can be understood that by providing the first positioning connection hole 22 and the second positioning connection hole 23, positioning pins can be respectively inserted into the first positioning connection hole 22 and the second positioning connection hole 23, so as to achieve precise positioning when installing the rear wheel cover later (the positioning pin there is inserted into the positioning hole of the rear wheel cover for positioning); in addition, the support seat 20 and the support plate 21 can support the large rear wheel cover 2 and the small rear wheel cover.

[0031] As a preferred embodiment; a connection area 24 is provided on the large rear wheel cover 2, and a third positioning connection hole 25, a fourth positioning connection hole 26 and a fifth positioning connection hole 27 are respectively provided on the large rear wheel cover 2 and near the periphery of the connection area 24; the purpose of providing the connection area 24 is to install the small rear wheel cover at the back, and after the small rear wheel cover is installed and positioned, it can be welded by a six-axis manipulator welding machine; in addition, the purpose of providing the third positioning connection hole 25, the fourth positioning connection hole 26 and the fifth positioning connection hole 27 is to further accurately position the rear end surface of the large rear wheel cover 2, and the third positioning connection hole 25, the fourth positioning connection hole 27 and the fifth positioning connection hole 28 can all be plugged with positioning pins, and the positioning pins are also connected to the sensor, and the positioning is performed by the positioning pins, and the position of the large rear wheel cover 2 at that place is sensed by the sensor;

[0032] It is worth mentioning that each locating pin can use a locating pin of different diameters according to the size of different holes. However, each locating pin is provided with a step, and the top of the locating pin is inserted into each locating hole, and the step can support the large rear wheel cover 2 or the small rear wheel cover; in addition, since the large rear wheel cover 2 has been effectively fixed in all directions in the present application, after connecting the small rear wheel cover, since the position of the large rear wheel cover 2 remains unchanged, the welding position of the small rear wheel cover will not be offset.

[0033] On the other hand, due to different working environments, the welding tooling of the present application will be connected to a slide for transportation.

[0034] The installation process of the utility model is as follows: first install the large rear wheel cover 2, and the two ends of the large rear wheel cover 2 will be inserted and positioned by the positioning pins 3 on the two positioning mechanisms, and the positioning pins at the third positioning connection hole 25, the fourth positioning connection hole 26 and the fifth positioning connection hole 27 at the rear end of the large rear wheel cover 2 are also plugged and positioned with the respective positioning connection holes on the large rear wheel cover 2, then, install the small rear wheel cover, and the first positioning connection hole 22 and the second positioning connection hole 23 are plugged with positioning pins, which can be plugged and positioned with the positioning holes on the small rear wheel cover, finally, start each clamping cylinder to drive the connecting rod clamp to flip, thereby effectively fixing the large rear wheel cover 2, and finally, the rear wheel cover can be welded by an external six-axis manipulator welding machine.

[0035] It should be pointed out that the main problems in the prior art are: the bolt fixing installation method consumes a lot of time in the process of installing and removing the rear wheel cover, resulting in reduced production efficiency. In addition, due to certain errors in the size and hole position of the rear wheel cover, the errors will be superimposed during the welding process, which will reduce the welding quality of the rear wheel cover.

[0036] Therefore, after the improvement of the present application, by providing a clamping mechanism and a positioning mechanism, and according to the setting of the number and position of the clamping mechanism and the positioning mechanism, the clamping mechanism can effectively fix the rear wheel cover 2 to avoid displacement, and the cylinder driving method is adopted, so that the rear wheel cover 2 can be quickly clamped and reset, reducing the time for installation and disassembly of the rear wheel cover 2, thereby greatly improving production efficiency; in addition, the positioning pin 3 and the sensor 4 on the positioning mechanism, the positioning pin 3 can effectively position the rear wheel cover 2, and further sense the installation position of the rear wheel cover 2 through the sensor 4, thereby ensuring the precise installation position of the rear wheel cover, thereby improving the welding quality of the rear wheel cover.

Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
