Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber reinforced plastic processing, and more specifically to a glass fiber reinforced plastic processing fixture. Background Art

[0002] FRP, or fiber reinforced plastic, generally refers to reinforced plastics that use glass fiber to reinforce unsaturated polyester, epoxy resin and phenolic resin matrices, with glass fiber or its products as reinforcing materials. After the FRP workpiece is processed, in order to facilitate its surface coating or further processing, the surface of the workpiece needs to be polished. In order to ensure the stability of the workpiece during polishing, the workpiece needs to be clamped.

[0003] Announcement No. CN218488555U proposes a fiberglass processing positioning fixture that realizes the clamping effect on the fiberglass by using a servo motor, a worm, a worm wheel, a first gear, a second gear, a first rack, a second rack, a clamping plate and a connecting rod. By setting the material of the clamping block to rubber, the clamping block is prevented from causing damage to the fiberglass. At the same time, the friction between the fiberglass and the clamping block is increased to prevent the fiberglass from shifting. By using threaded support legs, support feet and adjusting nuts, the balance adjustment of the main box is achieved to prevent the main box from shaking due to uneven ground, which affects normal processing operations.

[0004] However, fiberglass workpieces are widely used. This material can be used to make workpieces of different shapes such as tables, chairs, benches, etc. Therefore, when clamping and fixing, it cannot be guaranteed that the clamping end is suitable for different workpieces. The clamping parts need to be adjusted according to the shape of the clamped workpiece, which is inconvenient. Therefore, we propose a processing fixture suitable for different fiberglass workpieces.

[0010] Technical effects and advantages of the utility model:

[0011] 1. The fiberglass processing fixture places the workpiece between two mounting boxes and starts the cylinder, which pushes the mounting box toward the workpiece. At this time, the end face of the T-bar overlaps the surface of the workpiece, and as the T-bar overlaps the surface of the workpiece, the T-bar adapts to the shape of the workpiece.
