Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
In one embodiment, referring to fig. 1-3, the small-space pneumatic internal pressure quick clamping device comprises a bottom plate 1, wherein the bottom plate 1 is fixedly connected with a housing 10, a connecting shaft sleeve 7 which moves up and down is arranged in the housing 10, two sides of the top end of the housing 10 rotate to connect the middle part of a pressing block 3, two sides of the top end of the connecting shaft sleeve 7 rotate to connect the end part of the pressing block 3, and an air cylinder 13 which drives the connecting shaft sleeve 7 to move up and down is arranged at the bottom of the housing 10. The cooperation of the pressing block 3 and the bottom plate 1 just fixes the piece 2 to be clamped, namely the product. The piston rod of the cylinder 13 is fixedly connected with the connecting shaft 6, a first pin shaft 8 matched with the connecting shaft sleeve 7 is arranged on the connecting shaft 6, and a spring 9 for driving the connecting shaft sleeve 7 to move upwards is arranged between the connecting shaft sleeve 7 and the shell 10. The two sides of the shell 10 are provided with second pin shafts 5, the second pin shafts 5 rotate to connect the middle part of the pressing block 3, the two sides of the connecting shaft sleeve 7 are provided with third pin shafts 4, and the third pin shafts 4 rotate to connect the end parts of the pressing block 3. Two air pipe connectors 14 are arranged on the side wall of the air cylinder 13, and the air pipe connectors 14 are connected with the first air pipe 11 and the second air pipe 12.
Working principle:
1. when the device is in a non-working state, the air cylinder 13 is retracted to be at the lowest position, and the connecting shaft 6 is driven to enable the pressing block 3 to be at the limit state of being lifted outwards and lowered inwards, so that products can be conveniently placed in the device;
