Description
Technical field
The present invention relates to a kind of torsion ring, specifically, it is related to a kind of torsion ring for being used to determine torsion.
Background technology
Pneumatic impact spanner is extensively using on assembly line, the characteristics of efficiency high fast with rotating speed, but pair with those to torsion
Place with strict demand, such as automobile assembly line, pneumatic impact spanner just seem unable to do what one wishes to determining torsion.Only tighten at present
The large scale equipments such as machine have turns round device surely, not only expensive, and because volume is big, can not deploy to use in many stations.This is
In place of the deficiencies in the prior art.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of torsion ring for being used to determine torsion, convenient adjustment pneumatic impact spanner
Determine torsion.
The present invention realizes goal of the invention using following technological means：
A kind of torsion ring for being used to determine torsion, including cylinder（2.2）, it is characterized in that：The cylinder（2.2）Two ends set respectively
There is big end cap（2.1）And small end cover（2.6）, the big end cap（2.1）And small end cover（2.6）Between be provided with and can rotate
Heart axle（2.3）, the cylinder（2.2）It is internally provided with symmetrical neck, the neck and is separately installed with symmetrical spring leaf
（2.4）, the spring leaf（2.4）It is fixedly connected with the big end cap（2.1）.
It is used as the further restriction to the technical program, the big end cap（2.1）And small end cover（2.6）Pass through jump ring
（2.5）It is installed on the cylinder（2.2）On.
It is used as the further restriction to the technical program, the central shaft（2.3）Stage casing be flat axle.
It is used as the further restriction to the technical program, the big end cap（2.1）Front end be provided with square shaft（2.10）.
It is used as the further restriction to the technical program, the cylinder（2.2）For cylinder.
It is used as the further restriction to the technical program, the big end cap（2.1）Front end connection pneumtic impact wrench（1）, it is described
Small end cover（2.6）Rear end be provided with sleeve（3）.
Compared with prior art, advantages and positive effects of the present invention are：The present invention's determines torsion for pneumatic impact spanner
Apparatus structure is simple, with low cost, may be mounted at and is used on common pneumatic impact spanner, common pneumatic impact spanner is had fixed torsion
The function of power, the torque force device of determining for being used for pneumatic impact spanner by increasing this on original pneumatic impact spanner transform and greatly save
Cost.When upper bolt, according to the torque of regulation, by adjusting the size of spring leaf quantity and central shaft, set it
Surely required torque is arrived, it is easy to adjust simple.When the torque for the screw-nut tightened reaches the torque of needs then, cylinder
Body is entered elastic deformation stage by the equal moment of reaction, now spring leaf, and the impact energy of pneumatic impact spanner is consumed, made
Bolt can not be sent to by obtaining impulsive force so that bolt can not continue fastening, so as to reach the effect for determining torsion.

Embodiment
The present invention is further described in detail with preferred embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1-Fig. 5, the present invention includes cylinder 2.2, and the two ends of the cylinder 2.2 are respectively arranged with the big He of end cap 2.1
Small end cover 2.6, is provided with the central shaft 2.3 that can be rotated, the cylinder 2.2 between the big end cap 2.1 and small end cover 2.6
Portion, which is provided with symmetrical neck, the neck, is separately installed with symmetrical spring leaf 2.4, and the spring leaf 2.4 is fixedly connected
The big end cap 2.1.Central shaft 2.3 is supported jointly by big end cap 2.1 and small end cover 2.6, and central shaft 2.3 can be in big end cap
2.1 and small end cover 2.6 support under rotate, big end cap 2.1 and small end cover 2.6 are spacing on cylinder 2.2 by jump ring 2.5, cylinder
The inside of body 2.2 has the neck for installing spring leaf 2.4（Not shown in figure）, and one end can block big end cap 2.1, prevent big
Rotated when 2.1 stress of end cap, spring leaf 2.4 is just clipped in the middle central shaft 2.3.Big end cap 2.1 has with pulling above
Gloves 3 square hole size identical square shafts 2.7 of cylinder.Central shaft 2.3 has the square hole shaft 2.8 and flat 2.9 axle structure being connected with pneumtic impact wrench 1
Into being installed in cylinder 2.2 and one end supported by small end cover 2.6, the other end is rotationally connected with the big axis hole of end cap 2.1.
The stage casing of the central shaft 2.3 is flat axle.
The front end of the big end cap 2.1 is provided with square shaft 2.7.
The cylinder 2.2 is cylinder.
The front end branch sleeve 3 of the big end cap 2.1, the rear end of the small end cover 2.6 is provided with pneumtic impact wrench 1.Thus
Common pneumtic impact wrench can be made to possess the effect for determining torsion.The square hole size of wrench socket 3 is identical with square shaft 2.7, and big end cap 2.1 passes through
Square shaft 2.7 is connected with sleeve 3.
The size and number of spring leaf 2.4 are selected when using the need for the torsion needed for, the length of central shaft 2.3 is selected
And width, the corresponding cylinder 2.2 of corresponding selection, the torque for making it be set to standard.During start-up operation, pneumtic impact wrench 1 drives center
Axle 2.3 is rotated, and because spring leaf 2.4 is installed in the neck of cylinder 2.2, and central shaft 2.3 is exactly in the folder of spring leaf 2.4
In seam, because spring leaf 2.4 and cylinder 2.2 and big end cap 2.1 are mutually permanently connected, so drive big end cap 2.1 to rotate, sleeve
2.2 are arranged on big end cap 2.1, and sleeve 2.2 can drive bolt to fasten.
Torque as defined in being reached when the screw-down torque of bolt and nut then, sleeve 3 by equal countertorque, this when
When the pulsed drive power for waiting the generation of pneumtic impact wrench 1 is delivered to spring leaf 2.4, spring leaf 2.4 can be caused to produce larger deformation,
In the process of inter-train pause, spring leaf 2.4 recovers automatically, so torque can not be delivered to bolt, what such pneumtic impact wrench 1 was produced rushes
Hit power just to be consumed by torsion ring 2, reach the effect for determining torsion.
Certainly, described above not limitation of the present invention, the present invention is also not limited to the example above, the art
The variations, modifications, additions or substitutions that those of ordinary skill is made in the essential scope of the present invention, fall within the guarantor of the present invention
Protect scope.
