[0002] Grating is a technology that combines digital technology with traditional printing. It can display different special effects on special films. The grating ruler actually plays a role in detecting the coordinates of the tool and the workpiece. It is often used in CNC machine tools to observe whether there is an error in the tool path, so as to compensate for the error in the tool movement. In fact, it is like the human eye seeing whether my cutting is off-center, and then it can serve as a standard for the hand to whether I need to adjust or change the force.

[0003] There are still certain deficiencies in the use of grating scale reading heads in the prior art. Traditional reading heads will be subject to certain wear during long-term sliding, which will increase the gap between the reading head and the grating scale, causing the reading head to slide and become stuck, making the reading head move less smoothly and affecting the stability of the reading head. Utility Model Content

[0004] The purpose of the utility model is to provide a grating scale reading head to solve the problem that the traditional reading head proposed in the above background technology will be subject to certain wear during the long-term sliding process, which will cause the gap between the reading head and the grating scale to become larger, resulting in the reading head sliding jamming, making the reading head move less smoothly, and affecting the stability of the reading head.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grating scale reading head, comprising a grating scale and a reading head, end covers are provided at both ends of the grating scale, the reading head is connected to the fixed slide groove through a fixed slider and is arranged above the grating scale, positioning slide grooves are provided on both sides of the fixed slide groove, an adjustment locking block is provided on the upper part of the fixed slider, a guide block is provided on the bottom of the adjustment locking block, positioning sliders are provided on both sides of the lower part of the fixed slider, a guide groove is provided on the inner side of the positioning slider, a fixed bottom plate is provided at the bottom of the reading head, fixing ears are provided at both ends above the fixed bottom plate, tightening adjustment bolts are provided inside the fixing ears, and a data connection line is provided at one end of the reading head.

[0006] In a further embodiment, the adjusting locking block is fixedly connected to the fixed slider by tightening the adjusting bolts, and both sides of the adjusting locking block are slidably connected to the positioning slider through guide blocks and guide grooves.

[0007] In a further embodiment, the cross-section of the guide block is configured as an inverted trapezoidal structure, and the guide block and the adjustment locking block are configured as an integral structure.

[0008] In a further embodiment, the cross section of the positioning slider is configured as a triangular structure, the surface of the positioning slot is configured as an inclined structure, and the positioning slider and the corresponding surface of the positioning slot have the same inclination.

[0009] In a further embodiment, both sides of the positioning slide block and the positioning slide groove are connected to the adjusting column through an adjusting groove, and the adjusting column and the adjusting groove are connected by sliding.

[0010] In a further embodiment, the guide groove and the positioning slide block are configured as an integral structure.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, the cross-section of the positioning slider is set to a triangular structure. Since the triangular structure has good stability, setting it to a triangular structure can increase the stability of the movement of the positioning slider and the positioning effect. During the long-term sliding process, it is not easy to be worn or shifted, thereby improving the smoothness of the sliding of the reading head, thereby solving the problem of the reading head getting stuck and being easier to use. The extended length of the positioning slider is adjusted by tightening the adjusting bolt. This operation method can simplify the installation steps of the slider. It only needs to mount the reading head on the top of the grating ruler, tighten the tightening adjusting bolt, lower the adjustment lock block, push the positioning slider to both sides, and fit tightly with the positioning slide groove, so as to lock the installation position of the reading head. The adjustment method is simple and easier to operate. BRIEF DESCRIPTION OF THE DRAWINGS
