Abstract
The utility model discloses a spacer pin puller of a short stress rolling mill. The spacer pin puller of the short stress rolling mill comprises a connection bolt head, a slide bar, a collision sleeve and a handle, wherein the handle is fixed to one end of the slide bar; a slide hole is formed in the middle of the collision sleeve; the slide bar is sleeved with the collision sleeve through the slide hole; a connection hole is formed in the other end of the slide bar; the connection bolt head structurally comprises a front bar, a nut and a rear bar; the front bar and the rear bar are connected to the two ends of the nut respectively; the front bar is provided with outer threads; the rear bar is movably connected to the connection hole. Due to the spacer pin puller of the short stress rolling mill, the detaching efficiency of a spacer pin is greatly improved, labor intensity of workers is relieved, maintenance is easy and convenient, the spacer pin puller is easy to use, and consumption of spare parts of the spacer pin is reduced greatly.
Description
Technical field
Utility model relates to a kind of maintenance tool, specifically, relates to a kind of short stress milling train spacer pin pin removal.
Background technology
When repairing short stress milling train, spacer pin need to be taken out from bearing block, because limited step and the bearing block of spacer pin tightly sticks together, often need to pick outward with flat chisel, spacer pin taking-up is very difficult.When spacer pin gets rusty, the taking-up of spacer pin just need to be repaired with gas welding is destructive, has a strong impact on operating efficiency.
Some obsolete spacer pin can directly clean with a pointed instrument, but there is a big chunk to hold spacer pin, can also continue to use.In unloading process in the past, this part spacer pin that can continue to use is often easily damaged when picking out, and has affected reusing of spacer pin, has improved rehabilitation cost.
Utility model content
The technical problem that the utility model solves is to provide a kind of short stress milling train spacer pin pin removal, has improved the efficiency of spacer pin dismantlement work, has reduced workman's labour intensity.
Technical scheme is as follows:
A short stress milling train spacer pin pin removal, comprises connecting bolt head, slide bar, compacting sleeve and handle; Described handle is fixed on an end of described slide bar, and described compacting sleeve middle part has slide opening, and described compacting sleeve utilizes described slide opening to be sleeved on described slide bar, and another end of described slide bar is provided with connecting hole; The structure of described connecting bolt head comprises front bar, nut and rear bar, and described front bar and described rear bar are connected to described nut two ends, and described front bar has external screw thread, and described rear bar is movably connected on described connecting hole.
Further: the cross sectional shape of described connecting hole is circular, in described connecting hole, has internal thread, and described rear bar has external screw thread, and the end of described rear bar and slide bar utilizes and is threaded, and the external screw thread of described rear bar and the external screw thread of described front bar are in the same way.
Further: the cross sectional shape of described connecting hole is square or hexagon, on the sidewall of described connecting hole, has through hole, and described rear bar has through hole, the through hole on the sidewall of described connecting hole and the through hole of described rear bar are installed with pin.
Further: the cross sectional shape of described connecting hole is square or hexagon, on the sidewall of described connecting hole, has screwed hole, and described rear bar has through hole, described screwed hole place is provided with jackscrew.
Compared with prior art, technique effect of the present utility model comprises:
1, use of the present utility model has improved the efficiency of spacer pin dismantlement work greatly, has reduced workman's labour intensity, keeps in repair easy, easy left-hand seat, greatly reduces the spare parts consumption of spacer pin.
2, the utility model is made according to the principle of active force and reaction force, and this instrument is single can be operated, time saving and energy saving, and has reduced staff's danger, strong assurance reusing of spare part.
3, the utility model highly versatile, changes after head bolt head, and pin removal also can be used for other small-sized field of pulling pin, as obtained checking when No. 2 vertical covers of our factory Bar Rolling Line are pulled pin.
4, connect economic benefit: 60 milling train * 8/platform * 120 yuan /=5.7 ten thousand+12 (raising the efficiency the newly-increased milling train quantity of repairing in the year after next) * 20,000 yuan/platform=29.7 ten thousand.
Accompanying drawing explanation
Fig. 1 is the structure chart of the short-and-medium stress milling train of the utility model spacer pin pin removal.
The specific embodiment
Below with reference to accompanying drawing and preferred embodiment, the technical solution of the utility model is elaborated.
As shown in Figure 1, be the structure chart of the short-and-medium stress milling train of the utility model spacer pin pin removal.
The structure of short stress milling train spacer pin pin removal comprises: connecting bolt head 1, slide bar 2, compacting sleeve 3 and handle 4.Handle 4 is fixed on an end of slide bar 2, and compacting sleeve 3 middle parts have slide opening, and compacting sleeve 3 utilizes slide opening to be sleeved on slide bar 2, and another end of slide bar 2 is provided with connecting hole; The structure of connecting bolt head 1 comprises: front bar 11, nut 12 and rear bar 13, and front bar 11 and rear bar 13 are connected to nut 12 two ends, and front bar 11 has external screw thread, and rear bar 13 is movably connected on the connecting hole of slide bar 2 ends.
The cross sectional shape of connecting hole can be square, hexagon or circle.Circular if, in the connecting hole of slide bar 2 ends, open internal thread, rear bar 13 has external screw thread, and the end of rear bar 13 and slide bar 2 utilizes and is threaded, and now, the external screw thread of the external screw thread of rear bar 13 and front bar 11 is in the same way.If the cross sectional shape of connecting hole is square or hexagon, need on leaving the sidewall of connecting hole, slide bar 2 open hole or screwed hole, in rear bar 13 relevant positions, open hole or screwed hole, utilize pin or jackscrew to connect rear bar 13 and slide bar 2.
In spacer pin top processing screw hole (M6*10), supporting with it, front bar 11 external screw threads (M6*15), just can screw in front bar 11 in spacer pin, just can utilize short stress milling train spacer pin pin removal to dismantle spacer pin.
In order to guarantee that the step surface of spacer pin is not damaged, the utility model utilizes the straight line moment pulling force that, back and forth impact force produces to act on spacer pin in the other direction, and spacer pin is taken out, and now spacer pin end face integral body is stressed, and removal efficiency obviously improves.Use procedure of the present utility model is as follows:
1, select suitable connecting bolt head 1, the rear bar of bolt head 1 13 is tightened on the connecting hole of slide bar 2 ends;
2, the front bar of bolt head 1 11 is screwed in the screw at spacer pin top;
3, hold handle 4, the compacting sleeve 3 that slides on slide bar 2 fast, and hit handle 4(and repeatedly make slide bar 2 collision compacting sleeves 3), make short stress milling train spacer pin pin removal intermittence pass to pulling force of spacer pin, until spacer pin is extracted.
