Description

Jacking mechanism

Technical Field

The application relates to the technical field of machining, in particular to a jacking mechanism.

Background

During production line operation, workpieces transferred from a previous station need to be processed at a current station, a jacking mechanism is often used for jacking the workpieces, then the operation of the current process is carried out, and after the operation of the current station is finished, the jacking mechanism descends to enable the workpieces to return to the production line to be transferred to the next station. Therefore, the jacking mechanism is used very frequently on the production line. However, the lifting and descending actions of the lifting mechanism used in the prior art are relatively violent, especially the starting stage is not smooth, the sudden starting action brings large vibration to the workpiece supported by the lifting mechanism, and the position of the workpiece is deviated due to the vibration, so that the accurate positioning of the workpiece is influenced, and the operation quality of the process or the next process is influenced.

Disclosure of Invention

The invention aims to provide a jacking mechanism to overcome the defects in the prior art.

In order to achieve the purpose, the invention provides the following technical scheme: the embodiment of the application discloses a jacking mechanism, which comprises a U-shaped fixing frame, a supporting piece, a clamping plate, a jacking plate and a jacking swing rod, wherein the U-shaped fixing frame is composed of an upper plate, a side plate and a bottom plate, the supporting piece penetrates through the upper plate and the lower plate, the clamping plate is sleeved on the supporting piece, one end of the upper side of the upper plate is provided with a safety clamping plate, the other end of the upper side of the upper plate is provided with a compression spring fixing rod, a compression spring is sleeved on the compression spring fixing rod, one end of the clamping plate is connected with the safety clamping plate, and the other end of; the jacking swing rod is connected with the fixed support through a rotating shaft, an extension spring is arranged on the lower side of the upper plate, and the extension spring is connected with the jacking plate.

Preferably, a pressing rod is arranged on the jacking swing rod, one end of the jacking plate is connected with the extension spring, and the other end of the jacking plate props the jacking swing rod with the pressing rod.

Preferably, the support member extends through the jacking plate.

Preferably, the rotating shaft is mounted at the center of the side plate.

Compared with the prior art, the jacking mechanism is simple in structure, convenient to use and capable of being widely applied to various working conditions.

Drawings

In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments described in the present application, and other drawings can be obtained by those skilled in the art without creative efforts.

FIG. 1 is a first schematic structural diagram of a roll bending machine according to an embodiment of the present invention;

fig. 2 is a schematic structural diagram of a roll bending machine according to an embodiment of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

Referring to fig. 1-2, the jacking mechanism of the present application is composed of a fixed frame 1, jacking

swing rods

2, 3, a clamping plate 3, a jacking plate 4, a supporting member 5, an extension spring 6, a compression bar 7, a safety clamping plate 8, a compression spring fixing rod 9, a compression spring 10 and a rotating shaft 11. The mount 1 is gone up and down to be opened porosely, support piece 5

passes mount

1, 2 one end of jacking pendulum rod is connected with mount 1 through pivot 11, depression bar 7 is connected to the other end, trompil in the middle of the cardboard 3, pass support piece 5, the one end card is on safe cardboard 8, compression spring 10 top is arranged in to the other end, safe cardboard 8 is connected fixedly with the mount, trompil in the middle of the jacking board 4, pass

support piece

5, 4 one ends of jacking board are connected with

extension spring

6, 6 one ends of extension spring are connected with mount 1, jacking board 4 is connected to the other end.

When the jacking swing rod 2 is rotated downwards, the pressure rod 7 is equivalent to a fulcrum at the moment, the fixed frame 1 is jacked upwards, the jacking swing rod 2 is rotated upwards, the jacking plate 4 is pulled upwards by the extension spring 10, and the fixed frame moves upwards in a reciprocating mode.

When the clamping plate 3 is pressed downwards, the fixing frame 1 moves downwards all the time and can stop after being loosened, and the functions of quick reset and quick downward movement can be realized.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
