Description

Technical Field

[0001] The utility model relates to the field related to the fixing of grating rulers, in particular to a ruler shell fixing mechanism of a grating ruler. Background Art

[0002] In the field of precision measurement and displacement control, the use of grating as a reference is internationally recognized as the most practical, economical and reliable technical measure to obtain high precision. The grating ruler measurement mechanism is a representative product to achieve this approach and is widely used in various machine tools, electromechanical equipment, and automated measurement equipment. When the grating ruler is installed as a measurement mechanism on two mutually moving components, the ruler housing is connected to one component to be measured, and the carriage body with the scanning mechanism is connected to the other component to be measured.

[0003] The existing device has the following shortcomings when in use: the staff generally uses bolts to fix the scale housing of the grating ruler to the equipment to be measured. When the grating ruler needs to be repaired or replaced, it is necessary to remove multiple bolts one by one and then install multiple bolts. This cumbersome step makes the disassembly and installation of the grating ruler more troublesome. Because the scale housing of the grating ruler is connected to the piece to be measured, it is easily affected by the temperature of the piece to be measured, resulting in thermal expansion and contraction, which affects the measurement accuracy of the grating ruler. Utility Model Content

When the grating scale needs to be repaired or replaced, it is only necessary to remove the fixing bolts at both ends of the grating scale housing and slide off the grating scale housing, and then replace the repaired or new grating scale, avoiding the tedious steps of removing multiple bolts one by one and then installing multiple bolts when the grating scale needs to be repaired or replaced, making the disassembly and installation of the grating scale more convenient.

[0006] In a further embodiment, a glass fiber layer is provided on the back side of the fixed plate, and an auxiliary sticker is adhered to the back side of the fixed plate. The glass fiber layer provided on the back side of the fixed plate can have a heat-blocking and heat-insulating effect on heat, thereby preventing the temperature of the test piece from being transferred to the grating ruler, causing it to expand and contract with heat, thereby affecting the measurement accuracy of the grating ruler.

[0007] In a further embodiment, side grooves are provided on both sides of the screw hole on the fixing plate, and the side grooves are located on both sides of the screw hole and are symmetrical on the left and right sides. A lower groove is provided on the fixing plate below the screw hole. The side grooves on the left and right sides of the screw hole and the lower groove below the fixing plate can alleviate part of the extrusion caused by deformation when the temperature changes, thereby improving the measurement accuracy of the grating ruler.

[0008] In a further embodiment, the fixing plate is provided with a plurality of screw holes with equal spacing therebetween, the fixing hole A is aligned with the fixing hole B in upper and lower positions, the fixing plate is provided with a plurality of screw holes with equal spacing therebetween, so that the fixing plate is firmly fixed to the workpiece to be measured, the fixing hole A is aligned with the fixing hole B in upper and lower positions, and the fixing hole A is provided at both ends of the grating scale housing.

[0009] In a further embodiment, the auxiliary sticker is a double-sided adhesive product, and one side of the auxiliary sticker is covered with a tear film. The auxiliary sticker is a double-sided adhesive product. When installing the fixing plate, tear off the tear film covering one side of the auxiliary sticker, and then use the auxiliary sticker to stick and fix the fixing plate to the piece to be tested, and then use the fixing screws to match the screw holes to fix it to the piece to be tested, so as to facilitate the fixation of the fixing plate and the piece to be tested.

[0010] In a further embodiment, the fixing screws installed in the screw holes are fixed to the piece to be tested, and the back side of the fixing plate is in close contact with the surface of the piece to be tested.

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

[0012] This avoids the tedious steps of removing and then reinstalling multiple bolts one by one when the grating scale needs to be repaired or replaced, making the removal and installation of the grating scale more convenient.

[0013] Avoid the problem that the temperature of the workpiece to be measured is transmitted to the grating ruler, causing thermal expansion and contraction, thereby affecting the measurement accuracy of the grating ruler. BRIEF DESCRIPTION OF THE DRAWINGS
