Abstract
The utility model discloses a tight-fitting bolt demolishs specialized tool for demolising tight-fitting bolt has the advantage that can improve and demolish efficiency. This tight fit bolt demolishs specialized tool, characterized by: the bolt dismounting device comprises a fixed support, wherein an ejection mechanism with an ejector rod is fixedly connected to the fixed support, and when the bolt is dismounted, the head of the ejector rod is matched with the end part of the bolt along the axis direction of the bolt. When the bolt is disassembled, the ejector rod of the ejection mechanism is aligned to the end part of the bolt, and the bolt is ejected out by the ejection mechanism.
Description
Technical field
The utility model relates to a kind of extracting tool, especially relates to a kind of driving fit bolt dismounting specific purpose tool that is used to remove driving fit bolt.
Background technology
At present, on technology history, connecting bolt for interference fit, because cooperating between the hole of the polished rod of bolt part and connected piece is quite tight, remove very difficultly, the common way of tradition is: pound with a hammer or hammer into shape to clash into by trip by manpower, quite take time and effort, in the steel rolling mill of the big production of continuous processing, seriously restricting and producing.The safety coupling connecting bolt of climbing rail beam factory universal mill has just run into a difficult problem that takes time and effort when removing.As the safety coupling of present use, its tight fit connecting bolt is more than the M42, and bolt is big, and interference fit is tight.In daily maintenance, service work, it is quite big to change processing bolt difficulty, and the processing time is long, only take hammering of foozle's power or trip hammer bump method to remove, the effort operation easier is big, and length expends time in, average annual in this respect consuming time about 15 hours, had a strong impact on production.
The utility model content
Technical problem to be solved in the utility model provides a kind of driving fit bolt dismounting specific purpose tool that driving fit bolt is removed efficient that improves.
The technical scheme that its technical problem that solves the utility model adopts is: driving fit bolt is removed specific purpose tool, it is characterized in that: comprise fixed support, fixedly connected ejecting mechanism on fixed support with push rod, when removing bolt, the head of push rod is engaged in the end of bolt along the axis direction of bolt.
Further be that the diameter of push rod is less than the diameter of bolt.
As optimized technical scheme, ejecting mechanism adopts hydraulic jack to make.
The beneficial effects of the utility model are: be fixed on on the bolted device by the utility model specific purpose tool, the push rod of ejecting mechanism is aimed at the end of bolt, with ejecting mechanism bolt is ejected, its simple in structure easy to operate, need not purchase, cost of manufacture is low, and when removing bolt, save time, laborsaving, improved operating efficiency greatly and won the time for producing, be particluarly suitable for removing on the bolt that tight fit connects and promote the use of.
Description of drawings
Fig. 1 is that driving fit bolt of the present utility model is removed specific purpose tool and the schematic diagram that is removed the part assembling.
Be labeled as among the figure: fixed support 1, ejecting mechanism 2, connected piece 3, bolt 4.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, driving fit bolt of the present utility model is removed specific purpose tool, comprises fixed support 1, fixedly connected ejecting mechanism 2 with push rod on fixed support 1, when removing bolt 4, the head of push rod is engaged in the end of bolt 4 along the axis direction of bolt 4.In use, at first be that the nut of connecting bolt 4 is laid down, then fixed support 1 is fixed on the connected piece 3 that connects with bolt 4 (when connecting shaft couplings as bolt 4, connected piece 3 is shaft coupling), aim at the end of bolt 4 with the push rod of ejecting mechanism 2, utilize push rod that bolt 4 is applied along the external force of bolt 4 axial directions, bolt 4 is ejected connected piece 3; And if load onto bolt 4, only need fixed support 1 and ejecting mechanism 2 reverse operatings are got final product.
In the above-described embodiment, in the time of before the push rod of ejecting mechanism 2 is pushing up bolt 4 on the surface of connected piece 3, the polished rod of bolt 4 partly all can being ejected the bolt connecting through hole of connected piece 3, then the push rod size of ejecting mechanism 2 can be made any size (size that is push rod can be greater than the diameter of bolt, also can be) less than the diameter of bolt, and when push rod still can not all eject the bolt connecting through hole of connected piece 3 with the polished rod part of bolt 4 behind the surface of bolt 4 being pushed up connected piece 3, then push rod need continue to enter the bolt connecting through hole and ejects operation, up to the bolt connecting through hole that the polished rod part of bolt 4 is all ejected connected piece 3, at this moment, the diameter of push rod should be less than the diameter of bolt 4.And after the diameter of push rod is set to diameter less than bolt 4, when bolt 4 breaks in connected piece 3, also can adopt ejecting mechanism 2 directly it to be ejected.
In the above embodiment, ejecting mechanism 2 can adopt versions such as four-bar mechanism, pneumatic cylinder to realize bolt 4 is ejected connected piece 3, as optimal way, ejecting mechanism 2 adopts hydraulic jack to make, hydraulic jack liftout bolt 4 is reliable, and ejecting force is big, and efficient is higher.
Claims (3)
1. driving fit bolt is removed specific purpose tool, it is characterized in that: comprise fixed support (1), go up fixedly connected ejecting mechanism (2) with push rod at fixed support (1), when removing bolt (4), the head of push rod is engaged in the end of bolt (4) along the axis direction of bolt (4).
2. driving fit bolt as claimed in claim 1 is removed specific purpose tool, and it is characterized in that: the diameter of push rod is less than the diameter of bolt (4).
