Workpiece rapid locating and clamping device

Abstract

The invention relates to a workpiece rapid locating and clamping device. The device comprises a base, a shaft seat, a guide seat, a clamping handle, a guide shaft, a distance adjusting bolt and a rear fixed check block. The shaft seat is arranged at the rear end of the upper surface of the base; and the guide seat is arranged on one side of the front end of the base, and the rear fixed check block is arranged on the other side of the front end of the base. The guide shaft is movably connected with the guide seat internally, and the distance adjusting bolt is arranged in the rear end of the guide shaft in a screwed manner; the rear end of the clamping handle is connected with the shaft seat through a bolt and an adjusting bolt, and a clamping plate is arranged at the lower end of the clamping handle; and an upper wedge-shaped surface and a lower wedge-shaped surface are arranged on the contact surfaces of the clamping plate and the head of the distance adjusting bolt, and a compression spring is arranged between the distance adjusting bolt and the guide seat. According to the workpiece rapid locating and clamping device, a workpiece can be rapidly located and clamped through the clamping handle, it is ensured that the machined size is accurate, and deformation is not prone to occur; fine adjustment of the locating position and fine adjustment of clamping force can be achieved through the upper wedge-shaped surface and the lower wedge-shaped surface on the clamping plate of the clamping handle; and through the compression spring, the adjusting clearance is removed, and the guide shaft is reset.

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...

Problems solved by technology

However, the positioning accuracy of the clamping device is poor, and the clamping force adjustment is inconvenient, especially the positioning position and clamping force cannot be adjusted after clamping, and it cannot be used for positioning and clamping workpieces with elastic deformation.
