[0002] The laser welding fixture is one of the key factors to ensure the welding quality. During welding, the fixture ensures that the relative position of the two parts to be welded remains unchanged. When thermal stress is generated during welding, the fixture ensures that the weldment does not deform with the thermal stress, thereby Ensure that the size and position of the weld seam to be welded will not change. Especially for laser welding, the requirements for the weld seam are higher. The diameter of the laser focus is about 0.2mm. Ways to ensure welding quality

Abstract
The invention relates to a focal length adjustable fixture moving along with a welding head. The focal length adjustable fixture comprises a welding head Y-axis sliding seat and a pressing wheel Y-axis sliding seat, wherein both the welding head Y-axis sliding seat and the pressing wheel Y-axis sliding seat are installed on a cross beam, a welding head servo motor is connected with a gear rack, the gear rack is respectively connected with the welding head Y-axis sliding seat and the pressing wheel Y-axis sliding seat, a pressing wheel Z-axis sliding seat is connected with the pressing wheel Y-axis sliding seat by virtue of a pressing wheel Z-axis linear guide rail, a pressing wheel Z-axis servo motor is connected with a pressing wheel Z-axis ball screw, the pressing wheel Z-axis ball screwis connected with the pressing wheel Z-axis sliding seat, a pressing wheel C-axis servo motor is connected with a pressing wheel bracket by virtue of a synchronous belt, the pressing wheel bracket isconnected with a pressing wheel, the pressing wheel is connected with a C-axis rotary shaft, and a CNC control device is electrically connected with the pressing wheel C-axis servo motor, the pressing wheel Z-axis servo motor, the welding head servo motor and a welding head Z-axis motor respectively. According to the focal length adjustable fixture, the stability of the welding quality can be preferably guaranteed, and the welding appearance is improved.
Description
Technical field [0001] The invention relates to a follow-up clamp in laser welding, in particular to an adjustable clamp that follows the movement of a welding head. Background technique [0002] Laser welding fixture is one of the key factors to ensure welding quality. During welding, the fixture ensures that the relative position of the two parts to be welded remains unchanged. When the welding generates thermal stress, the fixture ensures that the welded part does not deform with the thermal stress. Ensure that the size and position of the weld to be welded remains unchanged. Especially for laser welding, the requirements for the weld are higher. The diameter of the laser focus is about 0.2mm. When the width of the weld is too large, the laser light will leak and there will be no Ways to ensure welding quality. The welding fixture can be kept in the welding position in real time during welding to ensure the best fixture effect. The invention is a fixture that can move synchr...
