Workpiece positioning and clamping apparatus

Abstract

The invention discloses a workpiece positioning and clamping apparatus, which comprises an upper clamping arm (1), a connection arm (2) and a lower clamping arm (3), wherein the three arms are sequentially connected, a clamping surface of the upper clamping arm (1) is parallel to a clamping surface of the lower clamping arm (3), the connection arm (2) is perpendicular to the clamping surface of the upper clamping arm (1), one lower clamping arm (3) end far away from the connection arm (2) is provided with a screw hole, inner threads are arranged in the screw hole, a screw rod (4) is arranged inside the screw hole, and outer threads on the surface of the screw rod (4) are matched with the inner threads of the screw hole. According to the present invention, with rotation of the screw rod in the screw hole, a distance between the top of the screw rod and the upper clamping arm can be changed so as to adjust clamping force between the top of the screw rod and the upper clamping arm, such that rapid replacements of blocking strips with different specifications are convenient, and advantages of safety, reliability, small size and simple operation are provided.

Description

technical field [0001] The invention relates to a woodworking tool, in particular to a workpiece positioning and clamping device. Background technique [0002] The gradual mechanization of China's wood processing industry began in the late Qing Dynasty. At this time, foreign businessmen established mechanized timber factories in China, and then developed wood processing factories for housing construction such as floors, doors and windows; at the beginning of the 20th century, they also set up factories to produce plywood. Since the mid-1950s, the production of plywood has developed, and then began to manufacture particleboard and fiberboard; surface decoration materials and laminated timber have also appeared one after another. This marks that China's wood processing industry has entered a modernization period centered on comprehensive utilization. In the modern wood processing industry, especially in the furniture manufacturing industry, wood planers are commonly used pow...

Problems solved by technology

However, if the width of the wood workpiece changes frequently, different shuttle boards need to be replaced frequently. Therefore, the matching amount of the shuttle boards is large, and it is troublesome to replace.
