Description

Technical Field

[0001] This utility model relates to a clamping device, specifically a clamping device for sponge processing. Background Technology

[0002] Sponges have a wide range of uses in daily life. The manufacturing process of sponges can be roughly divided into the milky stage, the initiation stage, cutting, drying, and finished product. In the current sponge cutting process, the sponge needs to be clamped. Because sponges are porous and soft, the clamping is achieved by the friction between the sponge itself and the clamping plate after contact, or by clamping in a way that increases wear and tear to facilitate processing.

[0006] As a further embodiment of this utility model: both the side clamp and the worktable are welded with slots for engaging the positioning mechanism. Threaded through holes can be opened on the slots, and the positioning mechanism inside the slots is secured by the cooperation of bolts with the threaded through holes.

The positioning mechanism 2 of the side clamping plate 1 is connected to a frame connected to the bottom of the worktable 7 via the hydraulic telescopic cylinder 4. The hydraulic telescopic cylinder 4 is extended and retracted by a hydraulic system to achieve the vertical and horizontal positioning of the side clamping plate 1 relative to the worktable 7, thus meeting different usage requirements. Specifically, when the side clamping plate 1 is vertical, it can assist in clamping the sponge to be processed.

[0015] Both the side clamping plate 1 and the worktable surface 7 are welded with slots 16 for engaging the positioning mechanism 2. Threaded through holes can be opened on the slots 16, and the positioning mechanism 2 is secured within the slots 16 by the cooperation of bolts with the threaded through holes.

[0016] One side of the slot 16 on the side clamping plate 1 is fixedly connected to the bearing seat A3. The bearing seat A3 is rotatably connected to one end of the hydraulic telescopic cylinder 4 via a shaft. The other end of the hydraulic telescopic cylinder 4 is rotatably connected to the bearing seat B5 via a shaft. The bearing seat B5 is fixedly connected to the slider. The slider is slidably connected to the rail 6. The rail 6 is fixedly connected to the frame connected below the worktable 7.

One side of the positioning pin fixing plate 10 is vertically fixedly connected to the tails of several positioning pins 13, with the tips of the positioning pins 13 facing the sponge to be clamped. Both the side clamping plate 1 and the worktable surface 7 are provided with inlet and outlet holes for the extension and retraction of the positioning pins 13. The diameter of the inlet and outlet holes can be much larger than the maximum diameter of the positioning pins 13 to facilitate production. An airbag 11 is provided between the other side of the positioning pin fixing plate 10 and one side of the mechanism support 15. Multiple airbags 11 can be connected in series through pipes, and pressure valves, exhaust valves, and inflation nozzles are installed on the pipes connecting the airbags to the air sources to facilitate the air pressure control of the airbags 11, thereby controlling the extension of the positioning pins 13.
