Abstract

The invention relates to a quick workpiece positioning and clamping device capable of adjusting the clamping force. A shaft seat is arranged at the rear end on the upper surface of a base; a guide seat is arranged on one side of the front end, and the upper surface of the other side of the front end is connected with a rear fixed baffle in an adjustable manner through a locking screw; an adjustment boss is arranged on the rear end face of the base; an adjustment screw is arranged between the adjustment boss and the rear fixed baffle; the interior of the guide seat is movably connected with a guide shaft; a distance adjustment bolt is screwed into the rear end of the guide shaft; the rear end of a clamping handle is connected with the shaft seat through a bolt and an adjustment nut; a clamping plate is arranged at the lower end of the clamping handle; an upper wedged surface and a lower wedged surface are arranged on the head contact area of the clamping plate and the distance adjustment bolt; a compression spring is arranged between the distance adjustment bolt and the guide seat. The quick workpiece positioning and clamping device can quickly position and clamp a workpiece through the clamping handle; due to the upper wedged surface and the lower wedged surface on the clamping plate of the clamping handle, fine adjustment on the positioning position and the clamping force is realized; the clamping force on the clamped workpiece can be adjusted by adjusting the position of the rear fixed baffle; the compression spring is used for eliminating an adjustment clearance and resetting the guide shaft.

Description

technical field [0001] The invention relates to a workpiece clamping device, in particular to a workpiece quick positioning clamping device. Background technique [0002] At present, tailor welding is usually used when welding and assembling workpieces. If the positioning cannot be performed during tailor welding, the size of the workpiece after tailor welding is difficult to ensure and the deformation is large, and it takes a lot of time to adjust. Therefore, Chinese Utility Model Patent No.: 201320037139.4 discloses a fast clamping device for workpieces. The base is provided with a shaft seat, and one end of the handle connected to the pressing block is hinged through the shaft and the shaft seat; the base is also provided with a first The fixed block and the guide seat, the guide seat and the guide shaft are slidingly matched; and a second fixed block is provided; the axis of the guide shaft is parallel to the shaft, and the first fixed block and the guide shaft are respe...
