As shown in fig. 1 to 5, an embodiment of the present application provides an annular feeding device, which includes a mounting frame 100 and an electric swing unit mounted on the mounting frame 100.

The electric rotating unit comprises a mounting plate 210 fixedly connected with the mounting frame 100, a feeding limiting piece 600 is fixedly arranged on the mounting plate 210, a driving wheel 330 and a driven wheel 350 are rotatably arranged on the mounting plate, a chain 340 is wound between the driving wheel 330 and the driven wheel 350, and a plurality of grabbing assemblies 400 for mounting a workpiece shaft 500 are mounted on the chain 340.

Wherein, the driving wheel 330 and/or the driven wheel 350 are connected with a power component, the grabbing component 400 is hung on the chain 340 and can slide relative to the chain 340, and the mounting plate 210 is further provided with a feeding limiting piece 600 which can be used for carrying out interference limiting on the position of the grabbing component 400 relative to the mounting frame 100 under the condition that the grabbing component 400 is mounted with the workpiece shaft 500.

It can be appreciated that, because the grabbing component 400 is hung on the chain 340, when the chain 340 rotates, the grabbing component 400 can move synchronously along with the chain 340, and when feeding, an operator installs the workpiece shaft 500 on the grabbing component 400, and when the workpiece shaft 500 moves along with the grabbing component 400 to the corresponding position of the feeding limiting piece 600, the feeding limiting piece 600 can limit the relative position of the workpiece shaft 500 and the mounting frame 100, so that the workpiece shaft 500 and the chain 340 can relatively displace, and the feeding temporary storage of the workpiece shaft 500 is realized.

In the embodiment of the application, with the adoption of the annular feeding device, when the workpiece shaft 500 is hung on the grabbing component 400, the grabbing component 400 can slide relative to the chain 340 under the limit of the feeding limit piece 600, so that the workpiece shaft 500 can stay at the corresponding position of the feeding limit piece 600, when the workpiece shaft 500 on the grabbing component 400 is taken away, the feeding limit piece 600 releases the limit of the grabbing component 400, the grabbing component 400 moves along with the chain 340 to perform the next working cycle, and the temporary storage of workpieces can be realized through the cooperation between the grabbing component 400 and the feeding limit piece 600, so that the overall beat of the production line is greatly improved.

It should be understood that the transmission form between the driving wheel 330 and the chain 340 is not limited to the above-mentioned one, for example, a belt transmission can be adopted between the driving wheel 330 and the chain 340, so long as a circulation loop of the workpiece shaft 500 can be formed, and detailed description thereof will be omitted.

In a preferred embodiment, as shown in fig. 1 and 2, the power assembly includes a fixing stand 230 fixedly disposed on the mounting plate 210, and a driving motor 310 is fixedly disposed on the fixing stand 230.

The power output end of the driving motor 310 is fixedly connected with the driving wheel 330, and the driving motor 310 can drive the driving wheel 330 to rotate when being started, so as to drive the chain 340 to perform rotary motion.

It should be understood that the arrangement form of the power assembly is not limited to the above, for example, a reduction unit can be further disposed between the power output end of the driving motor 310 and the driving wheel 330, or the driving motor 310 can be directly connected to the driven wheel 350, so long as the driving of the circulation loop of the workpiece shaft 500 can be achieved, which is not described herein in detail.

In a preferred embodiment, as shown in fig. 1 and 2, a limiting frame 220 surrounding a chain 340 is fixedly disposed on the mounting plate 210.

The grabbing component 400 is disposed between the limiting frame 220 and the chain 340, and the limiting frame 220 can limit the grabbing component 400 in the horizontal direction.

In a preferred embodiment, as shown in fig. 1 to 5, the grasping assembly 400 includes a sliding frame 410 hung on the chain 340 and capable of sliding with respect to the chain 340, and a finger 430 elastically sliding in a gravitational direction provided on the sliding frame 410.

Wherein the claw 430 is used for hanging and installing the workpiece shaft 500, when the claw 430 is installed on the workpiece shaft 500, the claw 430 moves to the side close to the ground relative to the sliding frame 410 under the gravity action of the workpiece shaft 500, and meanwhile elastic potential energy is accumulated between the claw 430 and the sliding frame 410.

In a preferred embodiment, as shown in fig. 1 to 5, the grabbing assembly 400 further includes a cancellation 450 fixedly disposed on the hook 430, and the loading limiter 600 is specifically a limiting and cancellation plate fixedly disposed on the mounting plate 210.

With the work piece shaft 500 mounted to the claw 430, the cancellation 450 moves toward the ground surface side and can abut against the stopper cancellation plate along the track side end of the chain 340.

It can be understood that the position of the sliding frame 410 and the hook claw 430 relative to the mounting frame 100 can be limited by abutting the limiting and resisting plate with the resisting plate 450, at this time, elastic potential energy is accumulated between the hook claw 430 and the sliding frame 410, the sliding frame 410 can slide relative to the chain 340, after the workpiece shaft 500 on the hook claw 430 is blanked at the position, the hook claw 430 is reset under the action of elastic force, the resisting plate 450 is separated from the limiting and resisting plate, at this time, the sliding frame 410 can move synchronously along with the chain 340, and thus the next working cycle is entered.

In the embodiment of the application, the annular feeding device is adopted, and the position of the hook claw 430 is adjusted by the gravity of the workpiece shaft 500, so that the limiting coupling between the grabbing component 400 and the feeding limiting piece 600 is realized, the structure is simple, an additional auxiliary device is not needed, and the feeding efficiency of the workpiece shaft 500 is further improved.

It can be appreciated that the setting form of the loading limiter 600 is not limited to the above-mentioned one, for example, the loading limiter 600 can be set to directly perform interference limiting on the workpiece shaft 500, that is, when the grabbing component 400 installs the workpiece shaft 500, the loading limiter 600 directly performs interference limiting on the workpiece shaft 500 at the longitudinally extending position of the workpiece shaft 500, at this time, the position limitation of the grabbing component 400 relative to the mounting frame 100 can also be achieved, and an elastic sliding structure is not required between the claw 430 and the sliding frame 410, but since the workpiece shaft 500 is suspended on the grabbing component 400, if the workpiece shaft 500 is directly limited, the position between the grabbing component 400 and the workpiece shaft 500 is offset, and the workpiece shaft 500 may fall off in the circulatory feeding process of the workpiece shaft 500, which is unfavorable for the suspension stability of the workpiece shaft 500.

It is difficult to see that when the grabbing component 400 and the feeding limiting part 600 adopt the coupling form, the feeding limiting part 600 limits the position of the workpiece shaft 500 relative to the mounting frame 100 indirectly by limiting the grabbing component 400, so that the connection stability between the grabbing component 400 and the workpiece shaft 500 is not affected, and the feeding stability of the workpiece shaft 500 can be ensured under the whole beat lifting.

In a preferred embodiment, as shown in fig. 1 to 5, the grabbing assembly 400 further includes a sleeve 420 fixedly disposed on the sliding frame 410, the claw 430 penetrates through and is slidably disposed in the sleeve 420, a limiting head 440 is fixedly disposed at one end of the claw 430 away from the ground, and an elastic member is fixedly disposed between the limiting head 440 and the sleeve 420.

It will be appreciated that when the workpiece shaft 500 is mounted to the fingers 430, the spring between the retaining head 440 and the sleeve 420 compresses under the force of gravity of the workpiece shaft 500, thereby providing the fingers 430 with a restoring force after the workpiece shaft 500 is fed.

In a preferred embodiment, as shown in fig. 1 to 5, the gripping assembly 400 further includes a limiting wheel 460 fixedly disposed on the sliding frame 410, and the limiting wheel 460 can abut against the limiting head 440 to limit the displacement of the limiting head 440 to a side far away from the ground.

It can be appreciated that when the workpiece shaft 500 is not mounted on the claw 430, the elastic member between the limiting head 440 and the counteracting 450 is in a compressed state, and the limiting wheel 460 abuts against the limiting head 440 to limit the displacement of the limiting head 440 away from the ground, so that the stable position of the claw 430 relative to the sliding frame 410 can be ensured.

It can be seen that if the limiting wheel 460 is not provided, when the workpiece shaft 500 is not mounted on the claw 430, plastic deformation is generated after the elastic member is stretched and compressed, and the limiting head 440 is not limited on one side away from the ground, so that the claw 430 is located at an elastic balanced position of the elastic member, and the elastic balanced position of the elastic member is difficult to determine, so that the position of the claw 430 is unstable, and the matching accuracy of the offset 450 and the feeding limiting member 600 is not facilitated.

In a preferred embodiment, the elastic member can adopt a structure such as a spring and an elastic rubber, so long as the longitudinal return of the hook 430 can be achieved, and the specific arrangement thereof will not be described herein.

In a preferred embodiment, as shown in fig. 1,2 and 5, the mounting plate 210 is further provided with a blank hook limiting member 700 capable of abutting and limiting the position of the hook 430 relative to the mounting frame 100 when the workpiece shaft 500 is not mounted on the hook 430.

It can be appreciated that when the grabbing component 400 is not mounted with the workpiece shaft 500 and moves to the position corresponding to the empty hook limiting member 700 along with the chain 340, the empty hook limiting member 700 can limit the relative position of the grabbing component 400 and the mounting frame 100, so that the grabbing component 400 and the chain 340 slide relatively, and loading temporary storage of the grabbing component 400 is realized.

In the embodiment of the application, the annular feeding device is adopted, and the snatch component 400 without the workpiece shaft 500 is limited by the empty hook limiting piece 700, so that temporary storage of the snatch component 400 is realized, the workpiece shaft 500 is conveniently installed on the snatch component 400 by an operator, and the integral beat of the feeding process is further promoted.

In a preferred embodiment, as shown in fig. 5, the blank holder 700 includes a holding abutment fixedly provided on the mounting plate 210.

Under the condition that the workpiece shaft 500 is not installed on the hook claw 430, the limiting head 440 does not move to the side close to the ground under the gravity action of the workpiece shaft 500, so that one side end along the track of the chain 340 can be abutted with the limiting abutment.

It can be appreciated that the position of the claw 430 relative to the mounting frame 100 can be limited by abutting the limiting abutment post with the limiting head 440, at this time, the sliding frame 410 can slide relative to the chain 340, after the claw 430 at the position mounts the workpiece shaft 500, the claw 430 drives the limiting head 440 to move towards the side close to the ground, so that the limiting head 440 is separated from the limiting abutment post, at this time, the sliding frame 410 can move synchronously with the chain 340, and thus the next working cycle is entered.

In the embodiment of the application, the annular feeding device is adopted, and the position of the hook claw 430 is adjusted by the gravity of the workpiece shaft 500, so that the limiting coupling between the grabbing component 400 and the empty hook limiting piece 700 is realized, the structure is simple, an additional auxiliary device is not needed, and the feeding efficiency of the workpiece shaft 500 is further improved.

In a preferred embodiment, as shown in fig. 1, 2 and 4 to 6, the chain 340 is fixedly provided with an engaging member 320, and the grabbing assembly 400 is hung on the engaging member 320 and can slide relative to the engaging member 320.

The balls 323 in the direction away from the ground face are abutted against the corresponding side end faces of the slide frame 410, and the balls 323 in the direction close to the ground face are abutted against the corresponding side end faces of the mounting plate 210.

In the embodiment of the present application, with the above annular feeding device, the sliding frame 410 is abutted with the balls 323 at the corresponding positions under the action of gravity, so that the relative position change between the sliding frame 410 and the connecting piece 320 is realized through the rolling of the balls 323, and meanwhile, the connecting piece 320 is abutted with the mounting plate 210 through the balls 323 at the bottom, so that the operation stability of the circulation loop of the connecting piece 320 is further improved.

It is to be understood that the form of the engagement between the engaging member 320 and the grabbing assembly 400 and the mounting plate 210 is not limited to the above, for example, the balls 323 can be disposed on the sliding frame 410 and/or the mounting plate 210, and the above effect can be achieved by the engagement between the balls 323 and the engaging member 320, so long as the engagement relationship between the grabbing assembly 400 and the chain 340 can be ensured, which is not described herein in detail.
