Description
Technical Field
The utility model relates to the technical field of assembling of spindle pull rod sets, in particular to an assembling tool for a spindle pull rod set.
Background
The main shaft is a shaft that receives power from an engine or a motor and transmits it to other members. The main axis is also called as the optical axis, which is the abbreviation of the main optical axis: having a symmetrical diameter in the optical train. For example, the major axis of the sphere is a straight line passing through the center of the mirror surface and perpendicular to the mirror surface. The principal axis of a lens or optical axis optical train is the line connecting the centers of the lens faces.
The assembly of the main shaft pull rod group at present has the following problems: 1. the traditional pull rod group assembling mode has two types: one is to fix the big end of the pull rod with disc spring by flat tongs or other tools, and to screw the connecting sleeve and the small end of the pull rod, and to apply torque to the connecting sleeve by wrench, so as to force the disc spring to lock. The method has low efficiency, consumes time and labor, and the disc spring has high rigidity, so that the pressure between the inner screw thread and the outer screw thread is high, the friction force is increased, and the screw threads are damaged. On the other hand, the phenomenon of abrasion and scraping between the pull claw connecting sleeve and the spring gasket is easy to occur; the other assembling mode is that one end of the screw thread of the pull rod group with the disc spring and the spring gasket is downward, the screw thread is completely extruded by a press machine, and the hand is screwed to the bottom and then locked by a spanner. When the screw thread is extruded, the central hole of the disc spring at the tail end is not aligned with the pull rod and is easily clamped on the step surface of the screw thread, so that the pull rod is deformed or the screw thread is broken, and the pull rod is scrapped. Meanwhile, the press machine is expensive, and the equipment cost is high; 2. when a press machine is used in the traditional pull rod assembling mode, radial constraint is avoided, during assembling, the press machine needs to be supported by hands to be radially fixed, the method is troublesome and labor-consuming, and meanwhile, the method is dangerous, and the situation that the side surface of a pull rod group flies out to hurt people is easily caused; 3. in the traditional pull rod set assembling mode, the surface is exposed outside, and the coated molybdenum disulfide is easy to pollute surrounding articles, equipment and clothes of assembling personnel. Therefore, we propose a tool for assembling the spindle pull rod set.
