Description

Technical Field

[0001] The utility model belongs to the technical field of glass fiber reinforced plastic storage tanks, and in particular relates to a floating grinding and marking device for glass fiber reinforced plastic storage tanks. Background Art

[0002] FRP tanks need to be polished and marked before drilling holes and bonding the fixed flanges. Polishing is to roughen the position where the external objects (such as flanges, lifting lugs and other workpieces) need to be bonded. After grinding, the glue is more firmly bonded; marking is to calibrate the position of the external objects (such as anchors, lifting lugs, ladders, etc.) to be connected, so as to facilitate the precise installation of the external objects. Due to the limitations of the actual manufacturing process, the upper and lower diameters of the tank body differ by about 5mm, and the overall shape is a truncated cone; the tank body will be partially thickened and raised when the head is spliced; the tank body winding process will cause the middle part of the tank body to become thinner. Therefore, the actual size of the FRP tank is not the ideal size in most cases. Moreover, after the FRP tank is installed and positioned, the installation axis and the ideal axis do not coincide in most cases, and there is radial runout when it rotates. Therefore, if a robot is used to clamp the electric spindle, the electric spindle equipped with a rigid grinding head or marking pen cannot be continuously polished and marked on the partially deformed tank body. If the work is forced, the concave part of the tank body cannot be polished; the protruding part of the tank body will damage the grinding head and the marking pen or destroy the tank body. Therefore, in the prior art, polishing and marking generally adopt manual processing procedures. Utility Model Content
