Description
Technical field
The utility model relates to the technical fields of automated production equipment.
Background technique
With the continuous promotion of production automation degree, more and more auto parts and components manufacturers are sought for more increasing
Accurately automatic assembly line production line produces speed.It generally requires to carry out series parts in the components installation process of automobile
It tightens.It is common it is traditional manually to tighten that there is working efficiencies low, tightens a series of deficiencies such as of poor quality, or even due to simultaneously not
Disconnected repeated work, is easy to produce fatigue state and then causes safety accident, such case has largely violated human engineering
Criterion solves this series of deficiency to improve, and component product is tightened addition by more and more automatic production lines
In the design of assembly line.Now many Japan, U.S. etc. country in succession all trades and professions using design specific tightening mechanism into
The components installation that row factory automation produces, the safety accident that can not only effectively avoid artificially participating in and cause are twisted with artificial
Tight processing fault not in place, while the work pace of whole production line is largely improved, produce huge economic effect
Benefit.But tightening mechanism used at present, structure is more complicated, and operation difficulty is big.
Summary of the invention
The utility model is designed a kind of automatic to solve the problems, such as that the installation of tiny components in automated production is tightened
The mechanism for tightening function of floating be can be realized to replace artificial tightening way, save cost of labor, while improving production efficiency
With production CPK, and meet ergonomics criterion, convenient for promoting.
The utility model to achieve the above object, adopts the following technical scheme that
A kind of floating automatic tightening mechanism, including tightening mechanism, one end of the tightening mechanism and the output of servo motor
Inside the shell, bearing plate, tightening machine is arranged close to the side of tightening mechanism on shell in axis connection, the output shaft setting of servo motor
Compression spring is arranged in periphery on structure close to bearing plate one end.
Preferably, the output shaft of the utility model servo motor is connected by one end of shaft coupling and connecting shaft, connection
The other end of axis is connect with one end of rotation tightening axle, rotates the other end connection tightening mechanism of tightening axle.
Preferably, thrust bearing is fixed in the two sides up and down of the utility model rotation tightening axle respectively.
Preferably, shaft housing is arranged in the periphery of the utility model rotation tightening axle.
Preferably, O-ring is arranged in the periphery of the utility model tightening mechanism.
Preferably, the utility model tightening mechanism by fixed pin with connect axis connection.
The utility model by adopting the above technical scheme, has the advantages that compared with prior art
1, the utility model chooses servo press, due to having pressure sensing in servo to realize whole rundown process
Device can show that relevant parameter is convenient for being arranged and adjust in tightening rotation.
2, the utility model increases a shaft coupling between servo motor and connecting shaft, avoids operating in tightening mechanism
Occurs the excessive problem of torque in journey.Shaft coupling, can be between components by operating as the connection equipment between rotation axis
Have the function that torque or shared rotation angle, while equipment protection can also be carried out to tooling device, prevents from going out in operation
Now damage.
3, the utility model passes through the cooperation of servo motor and shaft coupling, and is fixed in rotation tightening axle using screw,
And it is fixed in the two sides up and down of rotation tightening axle with thrust bearing.Thrust bearing can undertake radial load, thus
Guarantee the accurate of shaft position during tightening rotation.
4, the utility model during tightening, for the product tightens mouth problem inconsistent there may be height, In
Compression spring is installed around below swingle, realizes the function of floating and tighten using the elastic force of compression spring.
5, the tightening mechanism part of the utility model is fixed by the O-ring of internal pin and outside, is utilized
It is limited with rotation axis horizontal direction so that screwed portion is rotated together with rotary shaft, is had reached close to product automatic tightening
Effect.
6, mechanism is tightened for specific products, in order to realize entire floating tightening mechanism in the mould of similar production line
Blockization replacement, only need to tighten module mechanism according to specific operating condition, changing mechanism lower end, close further according to factors such as carrying and strokes
Reason selection servo motor, scalability are stronger.

Specific embodiment
The technical solution of the utility model is described in detail with reference to the accompanying drawing:
As shown in Figure 1 and Figure 2, a kind of floating automatic tightening mechanism, including tightening mechanism 6, one end of the tightening mechanism 6
It is arranged in mechanism shell 2 with the output shaft of the output axis connection of servo motor 1, servo motor 1, close to stubborn on mechanism shell 2
Bearing plate 4 is arranged in the side of tight mechanism 6, and compression spring 5 is arranged in the periphery of close 4 one end of bearing plate on tightening mechanism 6.
As shown in Fig. 2, the output shaft of the utility model servo motor 1 is connect by shaft coupling 3 with one end of connecting shaft 7,
The other end of connecting shaft 7 is connect with one end of rotation tightening axle 9, and the other end of rotation tightening axle 9 connects tightening mechanism.
As shown in Fig. 2, thrust bearing 8 is fixed in the two sides up and down of the utility model rotation tightening axle 9 respectively.
As shown in Fig. 2, shaft housing 10 is arranged in the periphery of the utility model rotation tightening axle 9.
As shown in Fig. 2, O-ring 11 is arranged in the periphery of the utility model tightening mechanism 6.
As shown in Fig. 2, the utility model tightening mechanism 6 is connect by fixed pin 12 with connecting shaft 7.
The course of work of the utility model is as follows, and as servo motor 1 is started to work, shaft coupling 3 provides the transmission of torque,
Connecting shaft 7 receives power effect and also starts to be rotated, and connecting shaft 7 passes through under connection rotation tightening axle 9 and rotation tightening axle
The tightening mechanism 6 at end is rotated under the action of torque together.
During entire rotation, bearing plate 4 is responsible for the load of carrying servo motor 1, mechanism shell 2 and shaft coupling 3
Lotus, while two thrust bearings 8 are fixed on the two sides up and down of rotation tightening axle 9 to undertake axis radial direction during axis rotates
Load, guarantee rundown process in it is steady.
When in tightening mechanism 6 product with need to the place of tightening start to dock when, due to rotation bring torque and and surface
Bring resistance is contacted, compression spring 5 starts to shrink, and the product in tightening mechanism starts rundown process due to the reason of screw thread.
In the process, detection adjustment can be carried out to real-time pressure and torque by the display on servo motor, when tightening
Journey terminates, and servo motor reversely rotates release product and moves upwards, and completes entire automatic tightening process.
