Workpiece jig with adjustable clamping angle

Abstract

The invention discloses a workpiece jig with an adjustable clamping angle for clamping workpieces. The workpiece jig comprises a base, a connection shaft, a handle, a ratchet wheel, a non-return tappet and a fixing component, wherein one end of the connection shaft penetrates through the base and is connected with the handle; the handle is used for fixing the connection shaft on the base; the ratchet wheel is arranged on the connection shaft; a workpiece is clamped between the connection shaft and the ratchet wheel; the fixing component is connected onto the other end of the connection shaft and is used for fixing the ratchet wheel and the workpiece on the connection shaft; multiple teeth are arranged on the upper edge of the ratchet wheel; the non-return tappet is arranged on the base; the non-return tappet is connected with the teeth of the ratchet wheel; and the workpiece can rotate along with the ratchet wheel and the connection shaft for angle adjustment. According to the workpiece jig, the connection shaft is rotated so that the ratchet wheel and the workpiece rotate jointly for angle adjustment, and a rotation angle can be determined according to the teeth on the ratchet wheel; and the function of angle adjustment of the workpiece jig is realized. During angle adjustment, adjustment is realized by releasing the handle and rotating the connection shaft; and the workpiece jig has the advantages of being simple in structure and convenient for angle adjustment.

Description

technical field [0001] The invention relates to the technical field of processing jigs, in particular to a workpiece jig with adjustable clamping angles. Background technique [0002] Fixtures are a large class of tools for woodworking, ironwork, fitter, machinery, electric control and other handicrafts, mainly as a tool to assist in controlling position or movement. It has been widely used before the industrial age, including mechanical fixtures, woodworking fixtures, welding fixtures, jewelry fixtures, and other fields. Drilling jig is a tool that can guide twist drilling equipment or other drilling devices to the exact center position of each hole by moving the mold, and can accelerate repeated positioning in the center of the hole on multiple interchangeable parts In ironworking practice, a typical practice is to leave a hard collar for each hole on the drilling jig to prevent the twist drill from cutting the jig.

Problems solved by technology

At present, the clamping devices used in the drilling and other processing procedures of shaft workpieces often have the following problems: when drilling or other processing operations are required to be performed on shaft workpieces at multiple angles along the circumference, the clamping device cannot adjust the clamping angle. , or the structure of adjusting the angle is more complicated, which brings inconvenience to the operation and reduces the processing efficiency
