Description

Workpiece positioning table for spraying process

Technical Field

The utility model relates to the technical field of rail vehicle door spray positioning, in particular to a workpiece positioning platform used in spray processing.

Background Art

During the production of rail vehicle doors, matte paint needs to be sprayed on the doors. During the spraying process, a workpiece positioning table is required to position the doors to facilitate the matte paint spraying process.

The existing patent announcement number CN216896585U discloses a manual spray workpiece clamping pan-tilt. By setting a vertical axis, a horizontal axis and a rolling axis, the constructor can operate the base to realize the overall movement of the pan-tilt. The workpiece to be sprayed is fixed to the rolling axis through a clamp to fix the pan-tilt as a whole. The rolling axis can be operated to realize the arbitrary swing of the workpiece in space. When one of the vertical axis, horizontal axis and rolling axis is not needed to work or the workpiece needs to stay at a certain position, the corresponding position can be locked by the vertical axis locking screw, the horizontal axis locking screw and the rolling axis locking screw to achieve this.

When the above device is performing spray positioning, it is necessary to manually adjust the rolling axis to change the angle of the workpiece, which reduces the spray efficiency. At the same time, constantly adjusting the position of the workpiece will also increase the manual workload. In view of the above problems, a workpiece positioning table for spray processing is proposed.
