Abstract
The utility model discloses a round pin promotion ware that expands that uses when being used for shaking table upset, including connecting axostylus axostyle (A), quality piece (B), root screw (C) and locknut (D), wherein connect the centre bore that axostylus axostyle (A) passed quality piece (B), root screw (C) and locknut (D) respectively through the screw hole with is connected the axostylus axostyle and is connected, the good back of assembly, quality piece (B) can move along connecting axostylus axostyle (A), the motion scope of quality piece (B) is root screw (C) and arrives the distance between the locknut (D). The utility model discloses an use of the ware shaking table turnover time that has significantly reduced is promoted to the round pin that expands to the round pin that need not just too difficultly can light will expand chooses out, and more importantly can eliminate the potential safety hazard of instrument in the use.
Description
Technical field
This utility model belongs to vibration rig technical field, is specifically related to a kind of device used when vibration table overturns.
Background technology
Along with the development of China's aerospace industry, needing to carry out development and the production of a large amount of spacecraft product every year, almost all of spacecraft product is intended to carry out dynamics environment test, and including vibration, impact and noise fest, and vibration test is the most universal among these.Vibration table carries the dynamics environment test of a large amount of each grade product, and almost every product is required to carry out the vibration test in three directions, and average every day, each vibration table needed to carry out the upset of a stage body, and often stage body of upset needs the time of about half a day.
Be connected by 12 expansion pins between oscillating table horizontal sliding table with adaptor, vibration table by flip horizontal to time vertical, need to take out 12 expansion pins, by T is excellent, expansion pin extracted before.Its principle is dependent on the frictional force between T rod and the bolt of expansion pin, drives expansion pin upwards when firmly lifting T rod, waste muscle power the most extremely and time.Take out 12 expansion pin required times nearly one hour completely.Having been found that during using that frictional force is inadequate, T rod is easily individually extracted by pulling force, has the hidden danger getting to people or product simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of utensil being applicable to and using during large vibration table upset, it is intended to solve the time-consuming, laborious of large vibration table upset and unsafe factor.
For reaching above technical purpose, the technical solution adopted in the utility model is:
The utility model discloses a kind of expansion pin used when vibration table overturns and promote device, including connecting axostylus axostyle A, mass B, root screw thread C and stop nut D, wherein connect the axostylus axostyle A centre bore through mass B, root screw thread C and stop nut D is respectively connected with being connected axostylus axostyle by screwed hole, after assembling, mass B can be along connecting axostylus axostyle A motion, and the range of movement of mass B is the distance that root screw thread (C) arrives between stop nut (D).
Wherein, connecting axostylus axostyle A length should be at more than 300mm.
Preferably, a length of 10mm of axostylus axostyle A upper and lower two ends M12 screw rod is connected.
Preferably, a length of 320mm of axostylus axostyle A is connected.
Preferably, the length of mass B should be 130mm.
Preferably, what mass B was middle holds distance for 100mm.
Further, root screw thread changes corresponding size according to expansion pin caliber size.
This utility model establishes an instrument used when can overturn for large vibration table, it is achieved that the quick upset of large vibration table.
Accompanying drawing explanation
Fig. 1 is the structure chart promoting device for large vibration table expansion pin of the present utility model.
Wherein, A is for connecting axostylus axostyle；B is mass；C is root screw thread；D is stop nut.
Detailed description of the invention
One of the present utility model being applicable to large vibration table turning tool structure below in conjunction with the accompanying drawings be further described, this explanation is merely exemplary, it is no intended to limit protection domain of the present utility model.
Fig. 1 shows that of the present utility model being suitable for promotes device structure for large vibration table expansion pin.The expansion pin that this instrument is applicable to use during vibration table upset promotes device, including connecting axostylus axostyle A, mass B, root screw thread C and stop nut D, vibration table expansion pin promotes device be made up of four Component compositions and have direction of motion E, wherein connecting the axostylus axostyle A centre bore through mass B, root screw thread C and stop nut D is respectively connected with being connected axostylus axostyle A by screwed hole.After assembling, mass B can be along connecting axostylus axostyle A motion.Root screw thread C and stop nut D is had to be connected up and down, so the range of movement of mass is the distance between root screw thread C to stop nut D because connecting axostylus axostyle A.
In a detailed description of the invention, connecting axostylus axostyle A length should preferably remain in 320mm at more than 300mm.
Preferably, connecting axostylus axostyle A upper and lower two ends M12 spiro rod length is 10mm.
In a specific embodiment, mass B length should be 130mm, and distance is held for 100mm in centre.
In a specific embodiment, root screw thread C is threaded connection with expansion pin.
In a specific embodiment, connecting axostylus axostyle A upward vertical movement by mass B, by inertia, expansion pin is being taken out of, complete work.
In another specific embodiment, it is to avoid pulling out expansion pin when being pulled out by T rod frictionally, frictional force is inadequate, occurs overexerting in the past, it may occur that personal damage or encounter product situation.
Although above detailed description of the invention of the present utility model to be given detailed description and explanation; but it should be noted that; we can carry out various equivalence according to conception of the present utility model to above-mentioned embodiment and change and amendment; function produced by it still without departing from description and accompanying drawing contained spiritual time, all should be within protection domain of the present utility model.
