The buffer gear is buffer spring, the both ends point of buffer spring as a further solution of the present invention,
Not with screwdriver bar and tighten transmission axis connection.
Described tighten is equipped with step chamber as a further solution of the present invention, in transmission shaft, buffer spring installation
Step chamber diameter compared with segment, what the end of screwdriver bar was inserted into step chamber is relatively large in diameter section.
The screwdriver bar includes the bar portion being made into integration and interconnecting piece as a further solution of the present invention,
Interconnecting piece is in being relatively large in diameter in section of step chamber.
The diameter of the interconnecting piece is less than bar portion, interconnecting piece and in platform as a further solution of the present invention,
The limited step of rank chamber opening cooperates, and the end positions of interconnecting piece are respectively equipped with the first limiting section being made into integration with it
With the second limiting section, the travel position and limited step of the first limiting section and the second limiting section are interfered.
Compared with prior art, the utility model has the beneficial effects that screwdriver bar is not direct with transmission shaft is tightened
Connection, by the design of buffer spring, when lock adhering mechanism downlink, the head end of screwdriver bar is contacted with screw to be non-rigid,
To prevent the coating of screw surface from being destroyed.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of batch bar flexibility fit body of automatic locking screw machine.

Fig. 3 is the existing structural schematic diagram for tightening transmission shaft and screwdriver bar referred in background technique.
In figure: 1- tighten transmission shaft, 2- screwdriver bar, 3- buffer spring, 4- step chamber, 5- limited step, 201- bar portion,
202- interconnecting piece, the first limiting section of 203-, the second limiting section of 204-.
Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all implementations consistent with this disclosure.On the contrary, they be only with it is such as appended
The example of device and method being described in detail in claims, some aspects disclosed in the present embodiment are consistent.
Embodiment 1
Please refer to Fig. 1~2, in the utility model embodiment, a kind of batch bar flexibility fit body of automatic locking screw machine, packet
Include to tighten and transmission shaft 1 and be mounted on the screwdriver bar 2 tightened on transmission shaft 1, in the present embodiment, by screwdriver bar 2 with tighten
Transmission shaft 1 is set as can produce relative motion in the axial direction, and screwdriver bar 2 and tightening is also equipped between transmission shaft 1
Buffer gear due to screwdriver bar 2 and tightens biography when lock adhering mechanism downlink makes the head end of screwdriver bar 2 and screw is contacted
Moving axis 1 can produce relative motion, and there is buffering therebetween, and the contact between screwdriver bar 2 and screw at this time is non-rigid
Contact, screwdriver bar 2 will not destroy the coating of screw surface.
In the present embodiment, the buffer gear be buffer spring 3, the both ends of buffer spring 3 respectively with screwdriver bar 2 and
The connection of transmission shaft 1 is tightened, certainly, other liquid damping materials or solid-state damping material with the same function can also be selected.
Embodiment 2
Please refer to Fig. 1~2, in the utility model embodiment, a kind of batch bar flexibility fit body of automatic locking screw machine,
On the basis of above-described embodiment: described tighten is equipped with step chamber 4 in transmission shaft 1, buffer spring 3 is mounted on the diameter of step chamber 4
Compared with segment, the end of screwdriver bar 2 is inserted into being relatively large in diameter in section of step chamber 4, Lai Shixian screwdriver bar 2 and tightens transmission shaft
1 is slidably matched, so that the two can produce relative motion in the axial direction.
Certainly, screwdriver bar 2 is fallen out of step chamber 4 in order to prevent, is connected also for guarantee screwdriver bar 2 reliable
Property, the screwdriver bar 2 includes that the bar portion 201 being made into integration and interconnecting piece 202, interconnecting piece 202 herein are in step
Chamber 4 is relatively large in diameter in section, the diameter of interconnecting piece 202 is less than bar portion 201, interconnecting piece 202 in 4 opening of step chamber
Limited step 5 cooperates, i.e., limited step 5 will not impact the proper motion of interconnecting piece 202, and the two of interconnecting piece 202
End position is respectively equipped with the first limiting section 203 and the second limiting section 204 being made into integration with it, the first limiting section 203 and second
The travel position and limited step 5 of limiting section 204 are interfered, and can be prevented screwdriver bar 2 from falling out of step chamber 4, can also be prevented spiral shell
The insertion depth of silk batch bar 2 is too deep.
It should be strongly noted that in the technical scheme, screwdriver bar 2 is not to be directly connected to transmission shaft 1 is tightened
, by the design of buffer spring 3, when lock adhering mechanism downlink, the head end of screwdriver bar 2 is contacted with screw to be non-rigid, when
