Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Example

[0033] Reference Figures 1-6 This is an embodiment of the present invention, which provides an automatic feeding device for machining center parts, comprising:

[0034] The supporting mechanism 100 includes a support platform 110, a feeding frame 120 fixedly connected to the top of the support platform 110, a discharge port 130 and a push port 140 respectively opened on both sides of the feeding frame 120, a fixed plate 150 disposed on the side of the push port 140 away from the discharge port 130, and a telescopic plate 160 slidably connected to the inner wall of the fixed plate 150.

[0035] It should be noted that the support platform 110 is the basic support structure of the entire device. It is used to support the feeding frame 120 and other related components to ensure the stability of the device. The feeding frame 120 is used to store the parts to be processed and provides temporary storage space for the parts. The discharge port 130 is the channel through which the parts are output from the feeding frame 120. The parts enter the subsequent conveying stage through this port. When the pusher block 217 enters the feeding frame 120 through the pusher port 140, it can push the parts towards the discharge port 130. The fixed plate 150 is used to provide the installation base for the telescopic plate 160. At the same time, it cooperates with the telescopic plate 160 to guide the parts to the processing center. The adjustment component 230 can not only adjust the angle of the fixed plate 150 to adapt to the feeding requirements of different parts, but also adjust the length of the telescopic plate 160 to meet the conveying distance requirements of different parts.

[0036] The conveying mechanism 200 includes a pusher assembly 210 for intermittently feeding parts stacked in the discharge frame 120 to the discharge port 130, which is located below the discharge frame 120.

[0037] The push assembly 210 includes a servo motor 211 adapted to be installed on the outside of the support platform 110, a connecting rod 212 fixedly connected to the output end of the servo motor 211 via a coupling, a cam 213 fixedly sleeved on the outer surface of the connecting rod 212, a hinge rod 214 hinged to the outer surface of the support platform 110 and used in conjunction with the cam 213, and a force groove 215 formed on the surface of the hinge rod 214.

[0038] And a transport assembly 220, located outside the discharge frame 120, for ensuring that the material delivered through the discharge port 130 smoothly enters the fixed plate 150.

[0039] Specifically, the pushing component 210 also includes a movable column 216 movably connected to the inner wall of the force application groove 215, a pushing block 217 fixedly sleeved on the outer surface of the movable column 216 and used in conjunction with the pushing port 140, a limiting guide rail 218 fixedly connected to the bottom of the feeding frame 120 and used in conjunction with the pushing block 217, and a tension spring 219 fixedly installed at the bottom of the feeding frame 120 and used in conjunction with the hinge rod 214.

[0040] It should be noted that the servo motor 211 is used to drive the connecting rod 212 to rotate, so that the connecting rod 212 drives the cam 213 to rotate synchronously. The rotation of the cam 213 uses the surface protrusion to intermittently squeeze the hinge rod 214, so that the hinge rod 214 swings under the squeezing of the cam 213. The force groove 215 drives the movable column 216 to move, and then the movable column 216 drives the pusher block 217 to move. The pusher block 217 moves linearly under the limit of the limit guide rail 218, preparing for the subsequent pushing action. The limit guide rail 218 is used to ensure that the pusher block 217 can perform horizontal linear movement, so that it can accurately complete the pushing action. When the squeezing effect of the cam 213 disappears, the tension spring 219 can provide a reverse force to the hinge rod 214, so that the pusher block 217 enters the discharge frame 120 through the push port 140, pushing the part to the discharge port 130.

[0041] Furthermore, a rotating bearing sleeve is installed at the connection between the connecting rod 212 and the support platform 110, the outer surface of the pusher block 217 slides in contact with the inner wall of the limiting guide rail 218, and the outer end face of the tension spring 219 is fixedly connected to the outer surface of the hinge rod 214.

[0042] When the cam 213 rotates continuously, it can intermittently squeeze the hinge rod 214 through the protrusion on its surface, so that the hinge rod 214 drives the movable column 216 and the pusher block 217 to move away from the pusher port 140 through the force groove 215.

[0043] After the external force of cam 213 is removed, hinge rod 214 can drive movable column 216 and push block 217 to move in opposite directions with the help of the reaction force of tension spring 219, so that push block 217 enters the feeding frame 120 through push port 140, and pushes the parts in feeding frame 120 toward fixed plate 150.

[0044] Preferably, the transport assembly 220 includes a first belt reel 221 fixedly sleeved on the outer surface of the connecting rod 212, a timing belt 222 sleeved on the outer surface of the first belt reel 221, a second belt reel 223 sleeved on the inner surface of the other end of the timing belt 222, and a feed roller 224 fixedly sleeved on the outer surface of the second belt reel 223.

[0045] It should also be noted that the first belt reel 221 can rotate synchronously with the connecting rod 212. Through its cooperation with the synchronous belt 222, it can drive the second belt reel 223 and the feeding roller 224 to rotate synchronously. Through the friction generated when the feeding roller 224 rotates, it can drive the parts to accurately enter the fixed plate 150 from the discharge port 130.

[0046] It should be noted that a rotating bearing sleeve is installed at the connection between the second belt reel 223 and the feeding frame 120. The bearing sleeve passes through and is fixedly installed on the inner wall of the feeding frame 120. The feeding roller 224 is located directly below the discharge port 130.

[0047] The feeding roller 224 can drive the material fed through the discharge port 130 into the fixed plate 150 accurately by rotating.

[0048] Furthermore, the conveying mechanism 200 also includes a control component 230 for flexibly adjusting the angle of the fixed plate 150 and the length of the telescopic plate 160, which is located on the outside of the feeding frame 120.

[0049] Specifically, the control component 230 includes a rotating column 231 fixedly mounted on the outer surface of the feeding frame 120 via bearings and used in conjunction with the fixing plate 150, a worm gear 232 fixedly sleeved on the outer surface of the rotating column 231, a worm 233 meshing with the outer surface of the worm gear 232, a fixing sleeve 234 fixedly connected to the outer surface of the fixing plate 150, a pull rod 235 movably connected to the inner surface of the fixing sleeve 234, a plurality of positioning grooves 236 opened on the surface of the telescopic plate 160 and used in conjunction with the pull rod 235, and a spring 237 sleeved on the outside of the pull rod 235.

[0050] It should be explained that the rotating column 231 provides rotational support for the fixed plate 150, and the worm gear 232 converts the rotational motion of the worm 233 into the rotation of the rotating column 231, which drives the fixed plate 150 to adjust its angle while locking it. The fixed sleeve 234 provides installation and movement space for the pull rod 235. When the pull rod 235 is inserted into the positioning groove 236 of the telescopic plate 160, it can limit the telescopic plate 160. When it is pulled out, it can release the limit on the telescopic plate 160, so that the length of the telescopic plate 160 can be adjusted according to actual needs. The spring 237 provides a reset force for the pull rod 235 to ensure that its position is maintained in the positioning groove 236, so as to ensure that the position of the telescopic plate 160 remains stable.

[0051] Preferably, the fixing plate 150 is fixedly connected to the outer end face of the rotating column 231, the worm gear 233 is fixedly installed on the outer surface of the feeding frame 120 through the bearing, and when the pull rod 235 is inserted into the positioning groove 236, it can limit the telescopic plate 160. The outer end face of the spring 237 is fixedly connected to the outer surface of the pull rod 235, and its other end abuts against the inner wall of the fixing sleeve 234.

[0052] When using,

[0053] The workpiece to be processed is placed in the feeding frame 120. The servo motor is started to drive the connecting rod 212 to rotate. The connecting rod 212 drives the cam 213 to rotate synchronously. The protrusion on the surface of the cam 213 intermittently presses the hinge rod 214, causing the hinge rod 214 to swing. The hinge rod 214 drives the movable column 216 to move through the force groove 215. The movable column 216 drives the pusher block 217 to move horizontally and linearly along the inner wall of the limiting guide rail 218, moving away from the pusher port 140.

[0054] After the squeezing action of cam 213 disappears, the reaction force of tension spring 219 drives hinge rod 214 to reset, and then the hinge rod 214 drives pusher block 217 to enter feed frame 120 through push port 140, pushing the part to discharge port 130.

[0055] At the same time, the first belt reel 221 rotates synchronously with the connecting rod 212. Through its cooperation with the synchronous belt 222, it drives the second belt reel 223 and the feeding roller 224 to rotate. Then, through the friction force generated by the rotation of the feeding roller 224, the parts are driven to accurately enter the fixed plate 150 from the discharge port 130. Subsequently, the parts are guided to the machining center through the fixed plate 150 and the telescopic plate 160, completing the entire feeding process.

[0056] When faced with the special feeding requirements of different parts: rotate the worm 233 to drive the worm wheel 232 and the rotating column 231 to rotate, and then adjust the angle of the fixed plate 150 by rotating the rotating column 231 to adapt to the feeding angle requirements of different parts;

[0057] Pulling the lever 235 to disengage it from the current positioning slot 236 allows for adjustment of the length of the telescopic plate 160 to meet the conveying distance requirements of different parts. After adjustment, releasing the lever 235 causes the lever 235 to re-insert into the corresponding positioning slot 236 via the reaction force of the spring 237, thus limiting the telescopic plate 160 and ensuring its stable position.

[0058] In summary, the cooperation between the carrying mechanism 100 and the conveying mechanism 200 not only eliminates the need for manual loading of materials one by one, significantly improving production efficiency, but also allows parts to enter the machining center from different directions and angles to meet the processing requirements of different parts. This ensures that the parts can accurately enter the machining center, thereby enabling the device to adapt to the feeding requirements of various special parts while improving the subsequent processing accuracy and product quality.
