Description

Workpiece inclination correction system

The present invention relates to a calibration system for a workpiece, and more particularly to a calibration system for adjusting the inclination of a workpiece.

In modern society, the competition in various industries is fierce. Invisible people also accumulate a lot of pressure due to the stress and busy work, which is easy to cause physical fatigue or mental exhaustion. Therefore, most people will choose to engage in leisure activities to relieve stress or change. The purpose of life mood, such as static activities such as reading and music, or dynamic activities such as dancing and playing, are ways to help regulate emotions and release stress. Therefore, the golf that is popular in foreign countries has developed rapidly in China in recent years. The biggest difference between golf and other ball games is that the active players will choose the most suitable club for the different terrain, distance or special ball.

Generally, the angle between the face of the club head and the neck is collectively referred to as Loft, and the bottom of the club head is close to the ground, and the angle between the neck and the ground is collectively referred to as Lie. Depending on the pole number, the above angles will also have different design ranges. If the angle of the club head is deviated, the player will not be able to play the expected ball path. The conventional club head manufacturing process mainly adjusts the angle of the neck by manual or mechanical means. Manual adjustment, for example, a device for emitting a laser beam at the neck of the rod, the angle of the beam being projected is determined by the position of the beam projection, and then adjusted by the personnel using the hand tool until the angle meets the standard, but it is difficult to control the club.
