Printer raster strip spring assembly jig

Abstract

The invention discloses an assembling jig for a grating strip spring piece of a printer. The assembling jig for the grating strip spring piece of the printer comprises a base; the bottom of the base is provided with a sliding grove which penetrates through the base from left to right and can be clamped on a movement shaft of a printing head; the base axially translates along the movement shaft of the printing head through the sliding groove; a mounting shaft is arranged at the top of the base; a positioning rod capable of being sleeved into a positioning hole in the grating strip spring piece is arranged at one end of the mounting shaft; a limiting sleeve is arranged at the shaft end, close to the positioning rod, of the mounting shaft in a sleeving mode; the other end of the mounting shaft is provided with a limiting inserting rod capable of being inserted into a side plate insertion hole of the ink-jet printing head; and a pressing mechanism which can tightly press the base on the movement shaft of the printing head and does not impede axial translation of the base on the movement shaft of the printing head is further arranged on the base. The assembling jig for the grating strip spring piece of the printer has the advantages that the assembly consistency of the grating strip spring piece can be effectively guaranteed and can be good, and the assembly quality of the grating strip spring piece can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of printer assembly equipment, in particular to a jig for assembling a spring sheet of a printer grating strip. Background technique [0002] In large printers, the printing of large paper is generally completed by the inkjet print head moving back and forth on the print head motion shaft supported between the left side plate of the printer and the right side plate of the printer, wherein the inkjet print head is on the print head motion shaft The moving position on the screen is positioned by the grating encoder, so there is a high requirement for the assembly accuracy of the grating encoder. Since the grating encoder is installed on the side plate of the printer through the grating strip spring, the assembly of the grating strip spring Accuracy also has higher requirements. Such as figure 1 As shown, the structure of the currently used grating strip spring is as follows: it includes a grating strip sprin...

AI Technical Summary

Problems solved by technology

Due to the inevitable movable gap between the adjustment hole and the stud on the grating strip spring, the grating strip spring is easily shifted during the process of being locked by the locking nut, so that it is impossible to ensure that the grating strip spring is always in position. Standard assembly stations lead to poor assembly consistency of grating strip springs and low assembly quality of grating strip springs
