Description
Technical field
The utility model relates to field of tool, specially a kind of pressing mechanism.
Background technique
Engineering machinery fitting device tooth type structures are more, and general tooth and toothholder are fixed by alligator, and tooth is through after a period of time
Serious wear just needs replacing, and needs first to remove alligator.
Currently, generally disassembly alligator requires special hydraulic pressing tool, equipment is larger, mobile inconvenient；Or it uses
Ejector pin bar knocks out alligator with hammer laser printer, labor intensive, and maintenance efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of manual pressing mechanisms, to solve behaviour mentioned above in the background art
The problem of making inconvenience, the labor intensive low problem of maintenance efficiency.
To achieve the above object, the utility model provides the following technical solutions:
A kind of pressing mechanism, including door word frame, ejector pin bar and driving screw；In the door word frame on any parallel frame face
It is respectively provided with a mutual corresponding through-hole, removal mouth of one of through-hole as alligator, another through-hole is set as threaded hole, uses
To be threadedly engaged with the driving screw；The door word frame packs into tooth type structures, and by external force, word frame and tooth type structures are carried out on the door
Positioning, so that alligator is located at the coaxial position of driving screw；The ejector pin bar is placed in driving screw coaxial position, one end of ejector pin bar
It is contacted with driving screw, the other end is contacted with alligator；The displacement of ejector pin bar is pushed by rotation driving screw precession, it will be in tooth type structures
Alligator is released.
Preferably, the driving screw is equipped with handle, rotates driving screw by rotating handle.
It preferably, further include extension pipe, which realizes adding for dismounting power on the handle, through extension pipe
It carries.
Preferably, there is anti-slip rubber between tooth type structures and door word frame, sliding when preventing from positioning.
Compared with prior art, the utility model has the beneficial effects that
The alligator that the pressing mechanism is suitable for different size dismounts, and packs into tooth type structures by door frame, is made by external force
It obtains door frame and tooth type structures positions, door frame can keep preferable linearity with alligator in a lateral direction, and occupy face
Product is small, structure is firm, and the load of dismounting power is realized by extension pipe, by anti-slip rubber auxiliary positioning, by replacing ejector pin bar
The alligator of the detachable different size of specification.The pressing mechanism, which overcomes, to be needed power source, fixes the problems such as cumbersome, and dimension is improved
It repairs, disassembly efficiency.
Detailed description of the invention
Fig. 1 is that the utility model axis regards structural schematic diagram.
In figure: 1, door frame, 2, anti-slip rubber, 3, ejector pin bar, 4, driving screw, 5, handle, 6, extension pipe.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, a kind of pressing mechanism, including door word frame 1, ejector pin bar 3, driving screw 4 and handle 5；The door word frame 1
In be respectively provided with a mutual corresponding through-hole on any parallel frame face, removal mouth of one of through-hole as alligator, separately
One through-hole is set as threaded hole, to be threadedly engaged with the driving screw 4；The door word frame 1 packs into tooth type structures, passes through external force
Word frame 1 is positioned with tooth type structures on the door, so that alligator is located at the coaxial position of driving screw 4；The ejector pin bar 3 is placed in master
One end of 4 coaxial position of screw rod, ejector pin bar 3 is contacted with driving screw 4, and the other end is contacted with alligator；Handle 5 is arranged in driving screw 4
On, 4 precession of driving screw is rotated by rotating handle 5, ejector pin bar 3 is pushed to be displaced, the alligator in tooth type structures is released.
Further embodiment:
It further include extension pipe 6,6 sets of the extension pipe on the handle 5, the load of dismounting power is realized by extension pipe 6.?
There is anti-slip rubber 2 between tooth type structures and door word frame 1, sliding when preventing from positioning.
Working principle: when using the pressing mechanism, needing the understanding for having in a structure to entire pressing mechanism first,
In use, door frame 1 is inserted in tooth type structures, positioned by the pressing and tooth type structures of outside operator, it is anti-skidding
Rubber 2 is bonded with tooth type structures side, and sliding when preventing from positioning makes alligator position be located at the coaxial position of driving screw 4, by ejector pin
Bar 3 is placed in 4 coaxial position of driving screw, and side and driving screw 4 are in close contact, while being directed at alligator, i.e. holding driving screw 4, top
Pin rod 3 and alligator are coaxial, rotate 4 movable top pin rod 3 of driving screw by rotating handle 5, connect 3 other end of ejector pin bar with alligator
Touching, is finally completed positioning, and upper extension pipe 6 is covered on handle 5, and by the applied force on extension bar 6, band fixed handle 5 rotates, and makes to lead
The rotation of screw rod 4 is mobile to push ejector pin bar 3 mobile, releases alligator.
The pressing mechanism uses lever design, can be adapted for the alligator dismounting of different size, is torn open by the realization of extension pipe 6
The load for filling power, by 2 auxiliary positioning of anti-slip rubber, by the alligator for replacing the detachable different size of 3 specification of ejector pin bar.
In conclusion the basic principles and main features and advantage of the utility model have been shown and described above.The industry
Technical staff is it should be appreciated that the present utility model is not limited to the above embodiments, and described in the above embodiment and specification
