Description

Technical Field

[0001] The utility model relates to the field of automobile parts processing equipment, in particular to a fender automatic welding device. Background Art

[0002] The main function of the fender of a car is to prevent mud, water and other dirt from splashing onto the vehicle or pedestrians. It can also reduce the damage to the bottom and parts of the vehicle caused by road splashing, and extend the service life of the vehicle. With the development of the automobile industry, customers have increasingly higher requirements for driving environment, such as sound insulation. Therefore, it is necessary to weld sound-absorbing cotton inside the automobile parts to maintain a quiet environment inside the car, and fenders are no exception.

[0003] CN202220727220.4 discloses an automatic welding device for sound-absorbing cotton for fender processing, including a machine base, on which is provided a support frame for supporting an external fender and a welding robot for welding the external fender on the support frame; the support frame is provided with a support module, and the support module includes a plurality of support components, and the support components include a support rod arranged on the support frame, and the support rod is provided with a support head, and the support head is used to support the middle part of the external fender and correspond to the welding point arrangement of the external fender; the support module also includes a support plate arranged on the support frame, and the support plates are two, which are respectively used to support the two ends of the external fender. When the device welds the sound-absorbing cotton to the external fender, the external fender with the sound-absorbing cotton is placed on the support module, and then the welding robot welds the sound-absorbing cotton to the external fender. The embodiment in the specification of the scheme also records that there are two support modules, and the motor is used as the driving mechanism to switch the work position to improve the welding efficiency. However, in actual use, due to the poor load capacity of the motor and the heavy weight of the structure such as the support frame, the movement position deviates, and even overheats and burns the motor.

[0004] Based on this, the technical problem solved in this case is: how to further optimize the fender automatic welding equipment. Utility Model Content

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] Example 1

[0016] See also Figures 1 to 4 A fender automatic welding equipment comprises a frame 1, a manipulator 2 arranged on the frame 1 for welding sound insulation cotton to an external fender, a rotating mechanism 3 arranged on the frame 1, and a supporting mechanism 4 arranged on the rotating mechanism 3; the supporting mechanism 4 is used to fix two external fenders; the supporting mechanism 4 is provided with a clamping module 43 for fixing the sound insulation cotton on the external fender; the rotating mechanism 3 is used to drive the supporting mechanism 4 to rotate; a plurality of universal ball seats 5 are provided on the frame 1; the universal ball seat 5 is arranged directly below the supporting mechanism 4 and the movable end of the universal ball seat 5 is kept tightly against the supporting mechanism 4.

[0017] Two external mudguards are fixed on the support mechanism 4 of this embodiment. In actual work, the two external mudguards are transferred to the welding station in turn by the rotating mechanism 3 to drive the support mechanism 4 to rotate, thereby realizing the separation of the welding station and the material changing station. During the welding process, the staff can remove the welded workpiece at the material changing station and replace the workpiece to be welded on the top of the support mechanism 4, thereby improving the welding efficiency. Moreover, in order to ensure that the rotating mechanism 3 can accurately and efficiently rotate the support mechanism 4, a plurality of universal ball seats 5 are added to the frame 1 and the universal ball seats 5 are set directly below the support mechanism 4, and the movable end thereof is kept in close contact with the support mechanism 4, thereby reducing the resistance to rotation and reducing the load of the rotating mechanism 3.

[0018] Specifically, the support mechanism 4 includes a fixed plate 41 arranged on the rotating mechanism 3, and a support frame 42 detachably arranged on the fixed plate 41; the two sides of the support frame 42 are respectively provided with clamping parts 421 matching the inner shape of the external mudguard; the clamping module 43 is arranged on the support frame 42.

[0019] Under the above design, the support mechanism 4 is divided into two parts. The fixed plate 41 is directly fixed to the frame 1 by fasteners, and the support frame 42 is detachably fixed to the fixed plate 41 to facilitate the replacement of tooling models, thereby expanding the application range of the equipment, and the tops of both sides of the support frame 42 are designed with clamping parts 421 to facilitate the staff to replace the workpiece, thereby improving the welding efficiency.

[0020] As a preference of this embodiment, the clamping portions 421 on both sides of the support frame 42 are arranged in a mirror image.

[0021] In practical applications, the rotating mechanism 3 only needs to drive the support frame 42 to rotate 180° to switch between the welding station and the material changing station. Of course, in addition to the method of this embodiment, those skilled in the art can change it according to the size and shape of the workpiece according to the specific situation.

[0022] More specifically, the pressing module 43 includes six pressing cylinders 431 disposed on the support frame 42 ; a pressing block 432 is disposed at the power output end of the pressing cylinder 431 .

[0023] In this embodiment, six clamping cylinders 431 are grouped into three to fix the workpieces on the clamping parts 421 on both sides of the support frame 42, and the three clamping cylinders 431 in the same group respectively clamp the sound insulation cotton at the left end, middle part and right end. In order to improve the clamping effect, the clamping block 432 is designed to be a long strip.

[0024] Specifically, the rotating mechanism 3 includes a rotating seat 31 and a power module 32 ; the fixing plate 41 is disposed on the rotating seat 31 ; and the power module 32 is used to drive the rotating seat 31 to rotate.

[0025] In order to improve the load capacity of the rotating mechanism 3, the power module 32 is a 180° swing cylinder, and the specific model is QGK125x180.

[0026] In this embodiment, in order to enable quick disassembly and assembly of the support frame 42, the fixing plate 41 is provided with a plurality of disassembly and assembly components 411 for fixing the support frame 42; the disassembly and assembly components 411 include a base 4111 arranged on the fixing plate 41, and a locking block 4112 hinged on the base 4111; the locking block 4112 is provided with a mounting hole 41121; the locking block 4112 is fixedly connected to the fixing plate 41 by bolts through the mounting hole 41121.

[0027] Under the above design, the support frame 42 is not only detachably fixed on the fixing plate 41, but also the support frame 42 and the fixing plate 41 can be separated by only removing the bolts between the locking block 4112 and the fixing plate 41 and then rotating the locking block 4112 hinged on the base 4111.

[0028] In order to reduce the travel of the robot 2 and further improve welding efficiency, the support mechanism 4 is arranged directly below the robot 2 .

[0029] In order to ensure that the support frame 42 rotates to a preset position, two positioning parts 412 are further provided at the bottom of the fixed plate 41; the frame 1 is provided with locking components 11 whose number is equal to and whose positions match the positioning parts 412; the locking component 11 includes a locking cylinder 111 fixed on the frame 1 and a positioning block 112 arranged at the power output end of the locking cylinder 111; the positioning block 112 cooperates with the positioning part 412 to lock or loosen the fixed plate 41 and the frame 1.

[0030] In actual application, the staff will place the workpiece on the upper support frame 42 according to the clamping part 421 at the material changing station and start the clamping cylinder 431 to fix the sound-absorbing cotton, and then control the rotating mechanism 31 to rotate 80°. Under the action of the swing cylinder, the rotating seat 31 is driven to rotate and the support seat is driven to rotate to complete the material changing process (of course, if the welding process is not completed at the welding station, the locking cylinder 111 remains extended and the swing cylinder will not move, and the locking cylinder 111 remains retracted during the material changing process to avoid affecting the normal rotation). After the workpiece enters the welding station, the robot 2 executes the preset path and welds the sound-absorbing cotton to the workpiece at the set welding point; repeat the above process for mass production.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
