Detailed Description

The technical solutions in the implementations of the present invention will be apparent from and fully described in conjunction with the accompanying drawings, which illustrate only some, but not all, embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 9, the embodiment of the present invention provides a high frequency oscillating device with adjustable oscillation amplitude, which includes a fixing plate 8, an oscillating plate 7 and a motor 2, wherein a groove for installing a crossed roller bearing 9 is provided on the fixing plate 8, an outer ring of the crossed roller bearing 9 is fixed on the groove, the oscillating plate 7 is fixed with an inner ring of the crossed roller bearing 9, and thus the oscillating plate 7 and the fixing plate 8 can rotate relatively. Or a pivoting support is arranged between the fixed plate 8 and the swinging plate 7 to realize the rotating connection between the fixed plate 8 and the swinging plate 7. The swing plate 7 is fixedly connected with a clamper 10, and the clamper 10 can be fixed with the swing plate 7 through bolts. The clamper 10 can be fixedly connected or hinged with an actuating device 1, and the actuating device 1 can be a welding gun, a polishing head, a laser cleaning tool and the like.

The gripper 10 can also be adapted to different configurations depending on the different actuators 1 to be gripped. In this embodiment, the welding gun is hinged to the holder 10, the holder 10 is provided with arc slots, and the bolts are fixed in different arc slots, so that the freedom degree of the welding gun can be adjusted, that is, the vertical angle of the welding gun can be adjusted, and the height of the head of the welding gun can be adjusted, so that the welding process is more adaptive.

The motor 2 is used as a power source, and the servo motor 2 or the stepping motor 2 is adopted, so that the motor 2 can be conveniently controlled, and the position precision of the welding gun after the motor 2 stops is ensured.

The output end of the motor 2 is connected with a speed reducer 3, and the speed reducer 3 is fixed on a mounting plate 4. The speed reducer 3 can increase the output torque of the motor 2, and the output power is more stable and reliable under the same parameters of the motor 2. The swing plate 7 is provided with a plurality of groups of positioning holes, such as ten groups or eight groups, and the mounting plate 4 can be fixed on any group of positioning holes through bolts. By changing the fit between the mounting plate 4 and the positioning hole, the position of the speed reducer 3 on the swing plate 7 can be changed.

The fixing plate 8 is provided with a long round hole, an output shaft of the speed reducer 3 is sleeved with an eccentric shaft 5, and the output shaft of the speed reducer 3 is inserted into the eccentric hole of the eccentric shaft 5. The eccentric shaft 5 is sleeved with a first gear, and the first gear is matched with the long round hole. When the motor 2 drives the eccentric shaft 5 to rotate through the speed reducer 3, the inner ring of the bearing 6 rotates together with the eccentric shaft 5, and the outer ring of the bearing 6 slides with the long round hole. It should be noted that when the width of the oblong hole is equal to the diameter of the outer ring of the bearing 6, the bearing 6 can be kept in a smooth sliding relationship with the oblong hole, and the oblong hole can be adapted to different positions of the bearing 6 on the fixing plate 8. Since the axis of the bearing 6 is offset from the axis of the output shaft of the speed reducer 3, the bearing 6 eccentrically rotates when the motor 2 rotates. The bearing 6 is arranged in the slotted hole in a sliding way, so when the bearing 6 rotates eccentrically, the swinging plate 7 and a cross roller bearing 9 of the fixed plate 8 can be driven to swing around the center.

The swing amplitude of the swing mechanism is related to the distance between the bearing 6 and the crossed roller bearing 9, when the installation position of the speed reducer 3 is close to the axle center of the crossed roller bearing 9, namely the bearing 6 rotates eccentrically at the position close to the axle center of the crossed roller bearing 9, the relative swing amplitude between the swing plate 7 and the fixed plate 8 is increased, and the increase of the swing amplitude of the welding gun is realized; when the speed reducer 3 is installed at a position far away from the crossed roller bearing 9, the swinging amplitude of the welding gun is reduced. The swinging amplitude of the welding gun can be conveniently adjusted by changing the mounting position of the speed reducer 3 on the swinging disc.

After the welding gun is fixed on the swing plate, the high-frequency swing of the welding gun can be realized, and the swing amplitude can be adjusted, so that the width of the surfacing welding and the thickness degree of the surfacing welding can be conveniently changed, and the welding effect is improved.

The utility model discloses an in a possible embodiment, also can not set up speed reducer 3, directly peg graft the output shaft of motor 2 in the eccentric orfice of eccentric shaft 5, change the position of motor 2 on swing board 7, can change the position of eccentric shaft 5 and bearing 6 to play the effect of adjusting the amplitude of oscillation. Compared with the scheme of arranging the speed reducer 3, the embodiment has the advantage that the output torque of the motor 2 is smaller.

In one possible embodiment of the present invention, the position relationship between the speed reducer 3 and the swing plate 7 can also be adjusted by the screw slider mechanism. If a screw slider mechanism is fixedly mounted on the swing plate 7, the speed reducer 3 is mounted on the slider, and the position of the slider is changed by rotating the screw, thereby adjusting the position of the speed reducer 3 on the swing plate 7.

When in use: the fixing plate 8 may be mounted on the arm of the welding robot. After the motor 2 is started, the motor 2 drives the output shaft of the speed reducer 3 to rotate, and the output shaft of the speed reducer 3 drives the eccentric shaft 5 to rotate. The eccentric shaft 5 eccentrically rotates. At this time, the axis of the bearing 6 on the eccentric shaft 5 and the axis of the output shaft of the speed reducer 3 are not aligned, and the bearing 6 rotates about the output shaft of the speed reducer 3. Since the bearing 6 is restricted in the oblong hole, when the bearing 6 eccentrically rotates, the fixed plate 8 and the swing plate 7 are brought into relative swing, and the swing of the welding gun on the swing plate 7 is realized. The swing range of the welding gun can be adjusted by changing the installation position of the speed reducer 3 on the swing plate 7.
