Description
Technical Field
The utility model relates to a mechanical assembly field particularly, relates to a screw nut's mechanism screws up.
Background
At present, on an assembly production line, a bolt (bolt) and a nut are manually pre-screwed in general for standard component assembly, and then a tightening machine is used for tightening, which is a way that the tightening machine realizes tightening from top to bottom when a conventional screw nut is arranged above the bolt; when the screw nut needs to be screwed below a workpiece, due to the fact that the operation space is small, when a conventional screwing machine cannot meet the use requirement, manual screwing is needed, the labor intensity of workers is greatly increased, the working efficiency is low, and the actual torque value of the screw nut cannot be unified within a required range.
An effective solution to the problems in the related art has not been proposed yet.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned technical problem among the correlation technique, the utility model provides a screw nut's mechanism screws up realizes that screw nut needs the frock of screwing up in the work piece below, and this frock is installed on the robot wrist, can screw up screw, nut more than M8 automatically at a certain station of assembly line to make the moment of torsion after screw nut screws up at the requirement within range, improve assembly efficiency and convenience greatly.
In order to achieve the technical purpose, the technical scheme of the utility model is realized as follows:
the utility model provides a screw nut's mechanism, includes fast trade dish, be provided with the tightening machine on the fast trade dish, the tightening machine is connected with the biasing head, biasing top of the head portion is rotated and is provided with rotatory mounting, the tightening machine with rotatory mounting transmission is connected, rotatory mounting slides and is provided with the slide bar, slide bar fixedly connected with sleeve, the slide bar with the sleeve with rotatory mounting rotates in step, the slide bar with be provided with the spring between the rotatory mounting.
Furthermore, the slide bar is connected with the sleeve through a pin shaft.
Further, the tightening machine is connected with a PLC controller.
Further, the sleeve is an inner hexagon.
Further, the tightening machine is connected with the rotary fixing piece through a transmission shaft.
The utility model has the advantages that:
1. the utility model discloses a connect the robot in order to realize that screw nut screws up in the work piece below is automatic to screw up the back at required moment of torsion within range. The tool is compact in overall structure, and can flexibly and freely realize space and multi-angle work.
2. The utility model discloses can the multi-angle screw nut of screwing up, it is limited mainly to solve the space on the assembly line, and the staff can't screw up screw nut through the instrument, and this frock simple structure, convenient operation practices thrift the cost of labor, and degree of automation is high.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a perspective view of a mechanism for tightening a screw and nut;
FIG. 2 is a cross-sectional view of FIG. 1;
fig. 3 is a diagram of practical application of a mechanism for tightening a screw nut.
In the figure: 1. the device comprises a biasing head, 2 a rotary fixing piece, 3 a sliding rod, 4 a sleeve, 5 a spring, 6 a tightening machine, 7 a quick change disc and 8 a nut.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
As shown in fig. 1-3, according to the embodiment of the present invention, a mechanism for tightening screw nut, including quick-change disk 7, quick-change disk 7 is provided with tightening machine 6, tightening machine 6 is connected with offset head 1, offset head 1 top is rotated and is provided with rotary mounting 2, tightening machine 6 with rotary mounting 2 transmission is connected, rotary mounting 2 slides and is provided with slide bar 3, slide bar 3 fixedly connected with sleeve 4, slide bar 3 with sleeve 4 with rotary mounting 2 rotates in step, slide bar 3 with be provided with spring 5 between rotary mounting 2.
In a specific embodiment of the present invention, the sliding rod 3 is connected to the sleeve 4 by a pin.
In one embodiment of the present invention, the tightening machine 6 is connected to a PLC controller.
In a specific embodiment of the present invention, the sleeve 4 is an internal hexagon.
In a particular embodiment of the invention, the tightening machine 6 is connected to the rotary mount 2 by a transmission shaft.
For the convenience of understanding the above technical solutions of the present invention, the above technical solutions of the present invention are explained in detail through specific use modes below.
When specifically using, according to the utility model discloses a screw nut's mechanism screws up, the robot passes through quick change dish 7 and connects the frock of figure 1, and the integral movement is to the required nut 8 below position of screwing up, and later the robot drives the whole upward movement of frock, stops after reacing the position of settlement, has two kinds of circumstances this moment, and the first condition is: the outer hexagon of the nut 8 is exactly parallel to the inner hexagon of the sleeve 4 completely, and the sleeve 4 can be sleeved on the outer hexagon of the nut 8 normally; the second case is: the outer hexagon of the nut 8 is not parallel to the inner hexagon of the sleeve 4, the sleeve 4 is applied with a downward pressing force of the nut 8, the slide bar 3 is connected with the sleeve 4 through the pin shaft, the slide bar 3 compresses the spring 5 downwards, the tightening machine 6 is controlled to rotate through the electric control system, the nut 8 cannot rotate under the condition of pre-tightening, when the inner hexagon of the sleeve 4 is parallel to the outer hexagon of the nut 8, the sleeve 4 is sleeved on the outer hexagon of the nut 8 under the force of the spring 5, the electric control system controls the tightening machine 6 to rotate and drives the rotary fixing piece 2 and the slide bar 3 to rotate through the biasing head 1, the sleeve 4 also starts to rotate along with the slide bar 3 until the sleeve tightens the nut 8 and stops after the required torque value is reached, and the electric control system sends an instruction to the tightening machine 6 to reverse 2 degrees after the stopping so as to prevent the nut 8 from exerting a reaction force on the sleeve 4 to influence the sleeve 4 to completely separate the sleeve 4 from the, at the moment, the robot drives the tool to move down integrally so that the sleeve 4 is completely separated from the nut 8, the robot moves to the next nut 8 position to be screwed, and the actions are repeated.
