Description

TECHNICAL FIELD

[0001] The present application relates to the field of coil processing equipment, in particular to a novel rotary jaw mechanism. BACKGROUND

[0002] In the processing of coils, such as coil winding or coil welding (generally such as stator welding plate or winding), in order to realize the overturning of the predetermined angle, the existing method is generally to overturn it directly through a rotating device.

[0003] However, with the setting of multi-connection structure, that is, processing multiple products at the same time, in order to realize the consistency of the overturning of multiple products, and further ensure the subsequent processing, the existing method is generally to use multiple sets of rotating devices, and to drive them respectively through servo rotating motors, thereby realizing the simultaneous processing of multiple products.

[0004] However, multiple sets of driving devices also have the following problems:

[0005] 1. The equipment cost of multiple sets of driving devices also increases, and the consistency adjustment and trial of multiple sets of driving devices in subsequent production is more troublesome, and the procurement cost and time cost are high;

[0006] 2. In order to ensure the same angle of the same coil, there is an adjustment gap for the coil that has not been rotated to the predetermined position, so there is a time lag when the processing mechanism processes multiple coils at the same time, which affects the production efficiency. SUMMARY

[0007] The main purpose of the present application is to provide a novel rotary jaw mechanism, which realizes the simultaneous rotation of multiple coils through a set of driving devices, and has a simple and stable structure, and effectively reduces the production cost.

[0008] In order to achieve the above purpose, the present application provides a novel rotary jaw mechanism, which comprises:

[0009] A rack is provided with a positioning plate and a base plate arranged at intervals;

[0010] A rotating shaft is pivotally installed on the positioning plate, and a plurality of rotating shafts are arranged at intervals;

[0011] A clamping cylinder is pivotally installed between the positioning plate and the base plate, the middle part of the rotating shaft is provided with a hollow channel, the hollow channel is provided with a pipeline connected with the clamping cylinder, the front end of the pipeline is connected with the clamping cylinder, and the rear end is connected with a hose or a rotating joint;

[0012] The clamping cylinder is fixedly connected with the rotating shaft;

[0013] The driving device comprises a synchronous wheel pivotally installed at the rear end of the rotating shaft and a driving belt connected with the plurality of synchronous wheels, the driving belt being connected with the rotating device and used to drive the plurality of synchronous wheels to rotate simultaneously.

[0014] The rear end of each rotating shaft is fixedly installed with a correction seat, and the frame is provided with a positioning point matched with the correction seat,

[0015] The rotating shaft is fixedly installed with at least one elastic driving structure, one end of the elastic driving structure being connected with the synchronous wheel and the other end being connected with the rotating shaft,

[0016] When the driving belt drives the synchronous wheel to rotate, the synchronous wheel applies a rotating force to the elastic driving structure, and the elastic driving structure stores a predetermined torsion force to drive the rotating shaft to rotate;

[0017] When the synchronous wheel rotates by a predetermined angle and stops, the torsion force stored in the elastic driving structure is released, and the correction seat continues to rotate, thereby driving the plurality of rotating shafts to rotate synchronously by a predetermined amplitude.

[0018] In actual design, when the driving belt drives the plurality of rotating shafts (i.e. multi-connection structure) to rotate simultaneously, the plurality of rotating shafts rotate simultaneously, but the rotating shafts are affected by errors, which may cause some rotating shafts not to rotate in place (i.e. the correction seat does not abut against the end of the positioning point), so that the elastic driving structure is arranged on the rotating shaft, i.e. the first torsion spring is compressed to drive the rotating shaft to rotate, and the correction seat abuts against the first positioning column, but some rotating shafts are affected by errors, so that the correction seat does not abut against the first positioning column, and the elastic force of the first torsion spring of the correction seat not contacting the first positioning column is released (the synchronous wheel is fixed, so the elastic force of the first torsion spring tends to the correction seat), thereby applying a torsion force to the correction seat and driving the rotating shaft to rotate, thereby realizing the synchronous movement of the multi-connection rotating shafts, and the synchronization is better, and the structure is simple and stable.

[0019] Meanwhile, the hollow channel avoids the problem of messy lines of the machine equipment, and the hollow channel can also be used to place the lines of the clamping air cylinder, thereby avoiding the messy lines.

[0020] Of course, the air cylinder has a lower cost and lower energy consumption, and meanwhile, the arrangement of the hose does not affect the input of the gas. BRIEF DESCRIPTION OF DRAWINGS

[0041] A rack provided with a positioning plate and a base plate arranged at intervals;

[0042] A rotating shaft pivotally installed on the positioning plate, the rotating shaft being provided with a plurality of rotating shafts arranged at intervals;

[0043] A clamping cylinder pivotally installed between the positioning plate and the base plate, the middle part of the rotating shaft being provided with a hollow channel, the hollow channel being provided with a pipeline connected with the clamping cylinder, the front end of the pipeline being connected with the clamping cylinder, and the rear end being connected with a hose or a rotating joint;

[0044] The clamping cylinder is fixedly connected with the rotating shaft;

[0045] A driving device comprising a synchronous wheel pivotally installed at the rear end of the rotating shaft and a driving belt connected with a plurality of synchronous wheels, the driving belt being connected with a rotating device, the driving belt being used to drive the plurality of synchronous wheels to rotate simultaneously;

[0046] The rear end of each rotating shaft is fixedly installed with a correction seat, the rack is provided with a positioning point matched with the correction seat,

[0047] The rotating shaft is fixedly installed with at least one elastic driving structure, one end of the elastic driving structure being connected with the synchronous wheel, and the other end being connected with the rotating shaft,

[0048] When the driving belt drives the synchronous wheel to rotate, the synchronous wheel applies a rotating force to the elastic driving structure, and drives the elastic driving structure to store a predetermined torsion force and then drives the rotating shaft to rotate;

[0049] When the synchronous wheel rotates by a predetermined angle and then stops, the torsion force stored in the elastic driving structure is released, and the elastic driving structure continues to drive the correction seat to rotate, thereby driving the rotating shafts to rotate synchronously by a predetermined amplitude.

[0050] In actual design, when the driving belt drives multiple rotating shafts (i.e., a multi-connection structure) to rotate simultaneously, the rotating shafts rotate simultaneously, but are affected by errors, which may cause some rotating shafts to not rotate to the position (i.e., the correction seat does not abut against the end of the positioning point), so the elastic driving structure is arranged on the rotating shaft, i.e., the first torsion spring is compressed by the synchronous wheel, thereby driving the rotating shaft to rotate, and the correction seat abuts against the first positioning column, but some rotating shafts are affected by errors, so the correction seat does not abut against the first positioning column, and the first torsion spring of the correction seat that does not abut against the first positioning column is released (the synchronous wheel is fixed, so the elastic force of the first torsion spring tends to move toward the correction seat), thereby applying a torsion force to the correction seat and driving the rotating shaft to rotate, thereby achieving synchronous movement of the multi-connection rotating shafts, and the synchronous movement is better, and the structure is simple and stable.

[0051] Meanwhile, the hollow channel avoids the problem of messy lines of the machine equipment, and of course, the hollow channel can be used to place the lines of the clamping air cylinder, thereby avoiding messy lines.

[0052] Of course, the air cylinder has a lower cost and lower energy consumption, and at the same time, the arrangement of the hose does not affect the input of the gas.

[0053] In actual design, the synchronous wheel does not drive the rotating shaft to rotate (i.e., a pivoting arrangement), so the driving torsion spring drives the rotating shaft to rotate, and when the torsion spring reaches the compression position, the rotating shaft is driven to rotate, and when the synchronous wheel stops, it can be understood as a fixed structure, so the elastic force of the torsion spring is released, and the correction seat or the linkage shaft is forced to rotate.

[0054] Meanwhile, the hollow channel 20 avoids the problem of messy lines of the machine equipment, and of course, the hollow channel 20 can be used to place the lines of the clamping air cylinder, thereby avoiding messy lines.
