Description

Laser welding fixture for unlocking handle of automobile seat

Technical Field

The utility model relates to a laser welding anchor clamps field especially relates to a car seat unblock handle laser welding anchor clamps.

Background

The relative position degree of the unlocking handle piece of the automobile seat and the synchronizing rod is particularly important in the assembling process of the backrest, and once the relative position degree is out of tolerance, the integral function of the backrest is disabled, so that the production efficiency and the quality of a product are directly influenced.

The prior art scheme adopts the profile modeling anchor clamps piece to press from both sides tight synchronizing bar usually, then with the welding of synchronizing bar and seat unblock handle piece, its weak point lies in: the synchronizing bar appearance is the flower type, and raw and other materials size is undulant great in the tolerance zone, and then leads to profiling fixture piece and synchronizing bar to have the unable tight condition of clamp, and then has leaded to the relative position degree discrepancy of unlocking handle piece and synchronizing bar after the welding is accomplished. When the existing technical scheme discovers an out-of-tolerance phenomenon, a proper position can be repeatedly found only by adjusting a mechanical structure, the speed is low, and the accuracy is low.

Further, the synchronization rod clamp 7 is a flat clamp.

The utility model discloses an useful part embodies:

(1) because the relative position degree of the unlocking handle piece and the synchronous rod is adjusted by adopting the rotation of the servo motor, the welding process has high precision and high speed;

(2) because two opposite edges on the synchronous rod are clamped by the plane fixture, the phenomenon of mistaken installation of the synchronous rod is prevented.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments, which are described herein for the purpose of illustration only and are not intended to limit the invention.

As shown in fig. 1 and fig. 2, the laser welding jig for the unlocking handle of the car seat of the present invention comprises a servo motor 1, a turntable 2, a clamping claw 3, a positioning pin 5, a synchronizing bar fixture 7, a tailstock 9, a slider 10, a sliding rail 11, a push rod 12, a handle 13 and a base 14, wherein the servo motor 1 is disposed on the base 14, the turntable 2 is fixedly connected with a rotor of the servo motor 1, the clamping claw 3 is disposed on the turntable 2, the positioning pin 5 is disposed on the turntable 2, the synchronizing bar fixture 7 is disposed on the right side of the servo motor 1, the sliding rail 11 is disposed on the right side of the synchronizing bar fixture 7, the tailstock 9 is disposed on the slider 10, the slider 10 is slidably connected with the sliding rail 11, one end of the push rod 12 is fixedly connected with the slider 10, the other end is provided with the handle 13, and the servo motor 1 and the tailstock 9 are coaxially arranged.

Further, the synchronization rod clamp 7 is a flat clamp.

Specifically, first, the unlocking handle piece 4 and the unlocking handle block 6 are fixed together to form a front end. The unlocking handle piece 4 is placed on the rotary table 2, the positioning pin hole in the unlocking handle piece 4 is matched with the positioning pin 5 in the rotary table 2, the unlocking handle piece 4 is ensured to be kept in a vertical state, and the clamping claw 3 is operated to clamp the unlocking handle block 6. One end of the synchronizing rod 8 is inserted into a central hole of the tailstock 9, and the height of the synchronizing rod clamp 7 is adjusted to enable the synchronizing rod 8 to be in a horizontal state.

As shown in fig. 3, the surface of the synchronizing bar 8 has 4 ribs, and the synchronizing bar 8 is axially rotated such that 2 ribs of the surface of the synchronizing bar 8 are opposed to the blocks of the synchronizing bar holder 7.

The operator holds the handle 13 and pushes the push rod 12 so that the free end of the synchronizing bar 8 approaches the unlocking handle piece 4 but does not contact the unlocking handle piece 4. Then, the rotation angle of the servo motor is set so that a diagonal line of the unlocking handle block 6 forms an angle of 45 degrees with a connecting line of two opposite edges of the synchronizing rod 8, at the moment, the unlocking handle piece 4 and the synchronizing rod 8 are in correct relative position degrees, and then the synchronizing rod clamp 7 is operated to clamp the synchronizing rod 8.

Finally, the operator holds the handle 13, pushes the push rod 12 to bring the free end of the synchronizing bar 8 into contact with the unlocking handle piece 4, and starts welding.

Because the synchronous rods of different batches have certain tolerance, when the relative position degree of the unlocking handle piece 4 and the synchronous rod 8 exceeds the tolerance, the rotating angle of the servo motor can be adjusted to ensure that the relative position degree of the unlocking handle piece and the synchronous rod is within the tolerance.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
