Description

G-clamp manual correction device

technical field

The utility model relates to a correction device, in particular to a G-shaped clip manual correction device.

Background technique

Woodworking clips are necessary tools for woodworking. They are simple in structure and dexterous to use. They are good helpers for woodworking. They are usually divided into F-type clips, G-type clips and A-type clips according to their shapes. The G-type clamp has two arms, one of which is a fixed end, and the other arm is provided with a screw hole, and a screw is screwed in the screw hole, and the workpiece can be clamped by turning the screw to adjust the distance between the screw end and the fixed end.

In order to ensure the stability of the clamping and the rationality of the force, the axis of the screw should be perpendicular to the plane of the fixed end, that is to say, the axis of the screw should pass through the center of the fixed end, so that it is more stable when clamping the workpiece without deflection force. Most of the current woodworking clamps are castings, so the arm where the screw hole is located will be deflected relative to the other arm. After the screw hole is processed, the axis of the screw hole is not perpendicular to the surface of the fixed end. When the error is large, the axis of the screw hole will be deviated. out of the fixed end.

Therefore, it is necessary to correct the G-clamp, mainly by means of hydraulic pressure, but there is a rebound after this correction, and the axis of the screw hole after correction cannot maintain the corrected state, so it is necessary to perform micro-calibration on the G-clamp. The existing G-clip micro-calibration is generally performed manually. First, a standard screw is inserted into the screw hole to observe whether the axis of the screw coincides with the center of the fixed end. If not coincident, perform micro-calibration on the arm where the screw hole is located. , if they coincide, no micro-calibration is required. In this way, regardless of whether micro-calibration is performed, the standard screw needs to be taken out, so the operation is troublesome and the efficiency is relatively low. If micro-calibration is not used, there are also inefficient operations such as taking out the screw.
