Clamping device for building engineering board punching

Abstract

The clamping device comprises a base, the inner surface of the base is in sliding connection with a bottom plate, the outer surface of the bottom plate is fixedly connected with a side plate, a support is arranged at the bottom of the side plate, the inner surface of the base is in threaded connection with a locking rod, and the locking rod is fixedly connected with the side plate. Adjusting devices are arranged on the two sides of the locking rod. According to the clamping device for building engineering plate punching, by arranging the fixing device, when a lever rotates, the lower surface of a clamping plate makes contact with and extrudes the upper surface of a plate, and before clamping is conducted, the vertical position of a screw can be controlled by adjusting a nut on the outer surface of the screw; the vertical position, located on the outer surface of the screw rod, of the lantern ring is controlled by adjusting the nut at the top of the lantern ring, under the action of the connecting rod, the clamping plate deforms so as to adapt to clamping of plates with different thicknesses, and the problems that a traditional clamping device is fixed in structure and limited in clamping range are solved.

Description

technical field [0001] The invention relates to the technical field of clamping devices, in particular to a clamping device for punching holes in construction engineering plates. Background technique [0002] Building boards are mostly used for the pavement of scaffolding pavements and the enclosure of cement molds. When in use, holes need to be drilled on the outer surface of the boards to facilitate the connection of the boards and improve stability and safety; [0003] When the traditional plate is drilled, there is a lack of external fixing and clamping devices. The plate is easy to rotate and vibrate under the drive of the electric drill, which will affect the positioning of the holes, resulting in the final hole position not being aligned, and the plates cannot be connected to each other. , or the tolerance of the connection is large, which affects the use effect.
