Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0013] like figure 1 As shown in the platen, the platen has a spherical shell part 10-1 set at one end of the platen body 10, the spherical shell part 10-1 is provided with a spherical cap surface; the spherical shell part 10-1 is provided with a belt The central threaded hole 10-2 of the positioning boss 10-3 is provided with a threaded hole 10-4 on the spherical shell portion 10-1 at an angle of 25 degrees to the axis of the central threaded hole.

[0014] like figure 2 The precision turning fixture of the fixed plate shown includes a connecting plate 2 connected with the main shaft flange 3 by bolts. A balance block 1 and a fixed plate positioning block 6 are respectively installed around the central hole of the connecting plate 2 through bolts, and are positioned on the fixed plate. The block 6 is provided with a stud 7 arranged at an angle with the central hol...

Abstract

The invention discloses a method for machining a prefocusing plate through a finish turning clamp. The method for machining a threaded hole in a spherical shell portion of the prefocusing plate through the finish turning clamp for the prefocusing plate comprises the following steps of 1, connecting a connecting disc of the finish turning clamp for the prefocusing plate with a spindle flange through bolts; 2, mounting the central threaded hole in the spherical shell portion of the prefocusing plate onto a double-end stud in a penetration manner, so that a locating boss on the spherical shell portion is arranged in a locating spigot, and after the prefocusing plate is adjusted, sequentially screwing nuts mounted on the double-end stud in a penetration manner, so that the prefocusing plate isfixed to a prefocusing plate locating block; and 3, starting a lathe spindle, drilling a threaded bottom hole through a drill bit in the first place, then, machining a taper hole in the front end ofthe threaded bottom hole through a turning tool, and then, tapping a thread in the threaded bottom hole through a reamer, so that the process is completed. Compared with the prior art, the method aimsat solving the problems that the threaded hole, forming a 25-degree angle with the axis of the central threaded hole, in the existing prefocusing plate is low in machining work efficiency and high inproduction cost.

Description

technical field [0001] The invention relates to the technical field of jig manufacturing, in particular to a processing method of a precision turning jig for a fixed plate. Background technique [0002] The fixed plate is one of the precision parts on the converter on the microscope. There is a fixed plate. The fixed plate has a spherical shell part set at one end of the fixed plate body. The spherical shell part is provided with a central thread with a positioning boss. A threaded hole is provided on the spherical shell part at an angle of 25 degrees to the axis of the central threaded hole. At present, the threaded hole on the spherical shell part at an angle of 25 degrees to the axis of the central threaded hole is the last process after finishing other parts, and it is carried out on a boring machine using a fixture; this processing method has the following problems: on the boring machine Processing of threaded bottom holes and threaded reaming has low work efficiency a...
