Description
Technical Field
[0001] This application relates to the technical field of automatic feeding for numerical control machine tools, for example, it relates to an automatic feeding bin for a numerical control machine tool. Background Art
[0002] Machining refers to a series of process operations such as cutting, grinding, stamping, and drilling on metals or other materials through various machine tools to manufacture parts or products with specific shapes, sizes, and precision requirements. Usually, various machine tools such as lathes, milling machines, drilling machines, and grinding machines are used. For example, lathes are mainly used for machining cylindrical parts, such as shaft parts.
[0003] The machining industry is currently in the process of comprehensively transforming to an automated production mode. As an important part of data automation, the automatic feeding system needs to be optimized and improved according to the application scenario. The mechanical dial bins of existing lathes are basically manual operations. The operator manually feeds the workpieces to be fed, and the equipment for docking the robotic arm with the material receiving robot has a high cost and low filling efficiency due to complex processes. Summary of the Utility Model
[0004] To have a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below. The summary is not a general review, nor is it intended to identify key / important constituent elements or delineate the protection scope of these embodiments, but rather serves as a preface to the subsequent detailed description.
[0005] Embodiments of the present disclosure provide an automatic feeding bin for a numerical control machine tool to solve the problems of high cost and low feeding efficiency.
[0006] To achieve the above object, the technical solution adopted by the present utility model is:
[0007] A CNC machine tool automatic feeding silo comprises a vertical frame and a conveying mechanism, wherein the conveying mechanism is arranged on one side of the vertical frame, and the material is self-sliding and conveyed inside the vertical frame by gravity, a top connecting plate is fixedly arranged on the top of the inner side of the vertical frame, the top connecting plate is used to temporarily store the material to be supplied, and one end of the top connecting plate is inclined downward, and the CNC cylindrical material will have a downward rolling tendency due to gravity, and the bottom side of the top connecting plate is sequentially arranged with an inclined first slide plate, a second slide plate, and a third slide plate from top to bottom, and the first slide plate and the third slide plate have the same inclination direction and are opposite to the inclination direction of the inclined end of the top connecting plate, so that the material can be fed to the machine tool automatically. The second slide is opposite to the first slide and the first slide is inclined in the opposite direction. The first slide, the second slide and the third slide are connected end to end. After the CNC feed is placed on the top connecting plate, the feed will roll outward under its own gravity, and then roll into the first slide, and then roll from the first slide into the second slide and the third slide in sequence. By setting three slides, more feed can be accommodated to achieve the purpose of temporarily storing more materials in the feed bin. The bottom end of the third slide is connected to the conveying mechanism, which is mainly composed of a conveying guide plate, a fixing frame, a lifting cylinder and a thumb cylinder. The plate is arranged horizontally and one end is connected to the bottom end of the third slide plate, so that the feed will naturally roll from the third slide plate to the conveying guide plate, and a fixing frame is arranged on the bottom side of the other end of the conveying guide plate, and a lifting cylinder is arranged on the inner side of the fixing frame, and a thumb cylinder is arranged on one side of the conveying guide plate, and the feed is blocked and moved by the thumb cylinder, and a lifting block with an adaptation groove is fixed on the output end of the lifting cylinder, and the adaptation groove space of the lifting block is larger than the volume of the feed. When the CNC machine tool is feeding, the feed is placed on the top connecting plate, and then it will roll into the first slide plate and the second slide plate in turn under the action of gravity. The plate and the third slide plate achieve the automation of material delivery by means of their own gravity, and then will be blocked on the conveying guide plate by the thumb cylinder. During the feeding, the thumb cylinder will push the adjacent feed to roll to the other end of the conveying guide plate, and finally roll into the adapter groove in the lifting block. After the lifting block receives the feed, the lifting cylinder will start to drive the lifting block to rise. After it rises to the supply position, the feeding workpiece will be taken away by the material receiving robot, completing a feeding cycle. This reciprocating cycle realizes automatic feeding and increases feeding efficiency. In addition, the device has a simple structure, simple assembly components, low cost, and saves costs.
[0008] Furthermore, side fixing plates are provided on both sides of the vertical frame, and a plurality of fixing screws are fixed on both sides of the first slide plate, the second slide plate and the third slide plate. The fixing screws pass through the corresponding side fixing plates and are fixed with nuts. The fixing screws cooperate with the side fixing plates to fix each slide plate.
[0009] Furthermore, the bottom of the vertical frame is provided with supporting legs, and the bottom ends of the supporting legs are provided with anchor plates, so that the supporting legs cooperate with the anchor plates to support the vertical frame.
[0010] Furthermore, an induction photoelectric eye is fixed on one end side of the conveying guide plate. The induction photoelectric eye is signal-connected to a PLC control cabinet. The PLC control cabinet is fixedly arranged on one side of the conveying guide plate and is signal-connected to a thumb cylinder and a lifting cylinder. During automatic feeding, the PLC control cabinet controls the processes of each component, and the induction photoelectric eye conducts signal feedback. After the feeding process starts, the PLC control cabinet first controls the thumb cylinder to pick up a feeding workpiece. When the workpiece rolls towards the lifting block, it will pass by the induction photoelectric eye. Then, the induction photoelectric eye will give a signal feedback to the PLC control cabinet, and the PLC control cabinet will control the lifting cylinder to drive the lifting block to rise, bringing the required feeding workpiece to the feeding position. After the feeding workpiece is taken away by the receiving robot, the PLC control cabinet controls the lifting cylinder to reset. This process is continuously repeated to achieve automatic feeding.
[0011] Furthermore, anti-detachment side plates are respectively arranged on both sides of the conveying guide plate. The height of the anti-detachment side plates is greater than the height of the feeding axis. The anti-detachment side plates can prevent the feeding workpiece from falling off the conveying guide plate. The thumb cylinder and the induction photoelectric eye are both fixedly installed on one side of the corresponding anti-detachment side plate, and the anti-detachment side plates support the thumb cylinder and the induction photoelectric eye.
[0012] Furthermore, retaining guide plates are fixedly arranged on the top end sides of the first sliding plate, the second sliding plate, and the third sliding plate. The retaining guide plates are in an arc shape curved towards their inner sides, which can well block the feeding workpiece that rolls too fast and prevent the feeding from jumping out of the range of the vertical frame.
[0013] Furthermore, a blocking plate is erected on one end side of the top contact plate. The blocking plate can block the feeding during feeding, which can prevent the feeding from rolling too fast and jumping out of the vertical frame.
[0014] Furthermore, a guiding vertical plate is arranged at the bottom of one end side of the conveying guide plate. The guiding vertical plate is vertical and is arranged in contact with the side wall of the lifting block. The guiding vertical plate ensures the stability of the lifting block during the lifting process and prevents it from swinging and causing the feeding workpiece to fall off.
[0015] The thumb cylinder and the PLC control cabinet are both prior arts, and those skilled in the art can clearly and correctly understand the present utility model and obtain relevant materials from existing literature.
[0016] A kind of automatic feeding bin for a numerical control machine tool provided by an embodiment of the present disclosure can achieve the following technical effects:
[0017] After placing the numerical control feeder on the top connection plate, the feeder will roll towards the inclined side under its own gravity, and then roll into the first slide plate, and then successively roll into the second slide plate and the third slide plate from the first slide plate. By setting three slide plates, more feeders can be accommodated. During the feeding process, the thumb cylinder will push the adjacent feeder to roll towards the other end of the conveying guide plate, and finally roll into the fitting groove in the lifting block. After the lifting block receives the feeder, the lifting cylinder will start to drive the lifting block to rise. After rising to the supply position, the feeding workpiece will be taken away by the receiving robot to complete a feeding cycle. This process repeats in a cycle to achieve automatic feeding, increasing the feeding efficiency. Moreover, the device has a simple structure, simple combined components, low cost, and saves costs.

[0025] In order to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of the present disclosure. In the following technical description, for the sake of explanation, numerous details are provided to give a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be shown in a simplified manner to simplify the drawings.
[0026] An automatic feeding bin for a numerical control machine tool includes a vertical frame 1 and a conveying mechanism 2. The conveying mechanism 2 is arranged on one side of the vertical frame 1 and slides and conveys automatically inside the vertical frame 1 by the gravity of the material. Legs 11 are provided at the bottom of the vertical frame 1, and floor plates 19 are provided at the bottom ends of the legs 11. The vertical frame 1 is supported by the cooperation of the legs 11 and the floor plates 19. A top contact plate 12 is fixedly arranged at the top inside the vertical frame 1. The top contact plate 12 is used to temporarily store the materials to be supplied, and one end of the top contact plate 12 is inclined downward. The cylindrical materials of the numerical control will tend to roll downward due to gravity. A blocking plate 121 is erected on one side of one end of the top contact plate 12. The blocking plate 121 is used to block the feeding during feeding, which can prevent the feeding from rolling too fast and jumping out of the vertical frame 1.
[0027] An inclined first sliding plate 14, a second sliding plate 15, and a third sliding plate 16 are sequentially arranged on the bottom side of the top contact plate 12 from top to bottom. The first sliding plate 14 and the third sliding plate 16 have the same inclination direction and are opposite to the inclination direction of the inclined end of the top contact plate 12. The second sliding plate 15 is opposite to the inclination direction of the first sliding plate 14 and the first sliding plate 14. The first sliding plate 14, the second sliding plate 15, and the third sliding plate 16 are connected end to end in sequence. Side fixing plates 13 are arranged on both sides of the vertical frame 1. A number of fixing screws 18 are fixedly arranged on both sides of the first sliding plate 14, the second sliding plate 15, and the third sliding plate 16. The fixing screws 18 pass through the corresponding side fixing plates 13 and are fixed with nuts. The fixing screws 18 cooperate with the side fixing plates 13 to fix each sliding plate. After placing the numerical control feeding on the top contact plate 12, the feeding will roll toward the inclined side under its own gravity, and then will roll into the first sliding plate 14, and thus will sequentially roll into the second sliding plate 15 and the third sliding plate 16 from the first sliding plate 14. By setting three sliding plates, more feedings can be accommodated, achieving the purpose of temporarily storing more materials in the feeding bin. Guide plates 17 are fixedly arranged at the top end sides of the first sliding plate 14, the second sliding plate 15, and the third sliding plate 16. The guide plates 17 are in an arc shape bent toward the inside of themselves, which can well block the feeding workpieces that roll too fast and prevent the feeding from jumping out of the range of the vertical frame 1.
[0028] The bottom end of the third slide plate 16 is connected to a conveying mechanism 2. The conveying mechanism 2 mainly consists of a conveying guide plate 21, a fixing frame 24, a lifting cylinder 25, and a thumb cylinder 27. The conveying guide plate 21 is horizontally arranged and one end thereof is connected to the bottom end of the third slide plate 16, so that the feeding material will naturally roll from the third slide plate 16 onto the conveying guide plate 21. A fixing frame 24 is arranged on the bottom side of the other end of the conveying guide plate 21. A lifting cylinder 25 is arranged inside the fixing frame 24. A thumb cylinder 27 is arranged on one side of the conveying guide plate 21 to block and push the feeding material through the thumb cylinder 27. The output end of the lifting cylinder 25 is fixed with a lifting block 26 provided with a fitting groove, and the space of the fitting groove of the lifting block 26 is larger than the volume of the feeding material.
[0029] When feeding a numerical control machine tool, the feeding material is placed on the abutting plate 12, and then it will roll into the first slide plate 14, the second slide plate 15, and the third slide plate 16 in sequence under the action of gravity to achieve the automation of material feeding by its own gravity. Then it will be blocked on the conveying guide plate 21 by the thumb cylinder 27. During the feeding process, the thumb cylinder 27 will push the adjacent feeding material to roll towards the other end of the conveying guide plate 21, and finally roll into the fitting groove in the lifting block 26. After the lifting block 26 receives the feeding material, the lifting cylinder 25 will start to drive the lifting block 26 to rise. After rising to the supply position, the receiving robot will take away the feeding workpiece to complete a feeding cycle. This process is repeated in a cycle to achieve automatic feeding, improve the feeding efficiency. And the structure of this device is simple, the combined components are simple, the cost is low, and the cost is saved. A guiding vertical plate 23 is arranged at the bottom of one end side of the conveying guide plate 21. The guiding vertical plate is vertical and is arranged in contact with the side wall of the lifting block 26, which can ensure the stability of the lifting block 26 during the lifting process and prevent it from swinging and causing the feeding workpiece to fall off.
[0030] An induction electric eye 28 is fixed on one end of the conveying guide plate 21, and the signal of the induction electric eye 28 is connected to the PLC control cabinet 3. The PLC control cabinet 3 is fixed on one side of the conveying guide plate 21 and is connected to the thumb cylinder 27 and the lifting cylinder 25 by signal. In the automatic feeding, the PLC control cabinet 3 controls the process of each component, and the induction electric eye 28 performs signal feedback. After the feeding process starts, the PLC control cabinet 3 first controls the thumb cylinder 27 to move a feeding workpiece. When the workpiece rolls to the lifting block 26, it will pass by the induction electric eye 28, and then the induction electric eye 28 will feedback the signal to the PLC control cabinet 3, and then the PLC control cabinet 3 controls The lifting cylinder 25 drives the lifting block 26 to lift and bring the required feeding workpiece to the feeding position. After the feeding workpiece is taken away by the receiving robot, the PLC control cabinet 3 controls the lifting cylinder 25 to reset. This process is repeated continuously to realize automatic feeding. Anti-slip side plates 22 are respectively provided on both sides of the conveying guide plate 21. The height of the anti-slip side plates 22 is greater than the height of the feeding axis. The anti-slip side plates 22 can prevent the feeding workpiece from falling off the conveying guide plate 21. The thumb cylinder 27 and the induction electric eye 28 are fixedly installed on one side of the corresponding anti-slip side plate 22, and the thumb cylinder 27 and the induction electric eye 28 are supported by the anti-slip side plate 22.
