Description

Technical Field

[0001] This utility model belongs to the field of drilling machine loading technology, and particularly relates to a CNC drilling machine with a positioning and loading mechanism. Background Technology

[0002] Currently, in the field of machining, CNC drilling machines, as the core equipment for achieving precise drilling of materials, are widely used in the production and processing of various products such as hardware parts, auto parts, and electronic components. As the manufacturing industry transforms towards automation and efficiency, the limitations of traditional CNC drilling machines in the material handling process are becoming increasingly prominent, making it difficult to meet the needs of modern mass production.

[0003] In traditional CNC drilling machines, the material loading process is highly dependent on manual operation. Operators need to place materials one by one on the machining station of the drilling machine. They not only need to focus continuously to ensure that the material placement is roughly accurate, but also need to frequently repeat the actions of picking up and putting down materials. Under this operation method, a single drilling machine usually needs to be equipped with at least one full-time operator. For mass production scenarios, not only does the labor cost increase significantly, but it is also limited by the speed of manual operation, resulting in low overall processing efficiency.

[0004] To address this issue, we propose a CNC drilling machine with a positioning and feeding mechanism. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a CNC drilling machine with a positioning and feeding mechanism, thereby reducing the labor intensity of operators.

[0021] Reference Figures 1 to 5 A CNC drilling machine with a positioning and feeding mechanism includes: Workbench 1 has a reserved slot in the middle, in which a first turntable 11 is rotatably installed. The first turntable 11 is used to push the material to make centrifugal motion. A second turntable 15 is set on one side above the first turntable 11. The second turntable 15 is rotatably installed on the workbench 1. A coupling is fixedly installed in the middle of the first turntable 11 and the second turntable 15. The other end of the coupling passes through the inner shaft of the bearing and is fixedly connected to the transmission shaft of the motor 3. The bearing is fixedly installed on the workbench 1. A material trough 16 is opened on the outside of the second turntable 15. The material trough 16 is used to receive the material. Drilling assembly, which is positioned above the second turntable 15; The feeding component is located above the first turntable 11 and is used to feed materials onto the first turntable 11. A limiting and guiding mechanism is installed on the outside of the first turntable 11 and the second turntable 15. The limiting and guiding mechanism is used to guide the material on the first turntable 11 sequentially into the material trough 16, below the drilling assembly, and at the end of the limiting and guiding mechanism. The positioning component is located on one side of the second turntable 15 and is used to clamp the material in the trough 16.

[0022] When this application is in use, after the CNC drilling machine is started, the unloading component first transports the material to the first turntable 11. The first turntable 11 rotates under the action of the drive device, and uses centrifugal force to push the material to the edge. At this time, the limiting guide mechanism restricts the movement trajectory of the material, so that the material enters the material trough 16 of the second turntable 15 along the preset path. The second turntable 15 rotates to transport the material in the trough 16 to the bottom of the drilling component. The positioning component then clamps and fixes the material. The drilling component starts to complete the drilling operation. After the drilling is completed, the second turntable 15 continues to rotate. Under the guidance of the limiting guide mechanism, the material is separated from the trough 16 and moves to the end of the limiting guide mechanism, and finally the material is discharged, realizing the material loading, conveying, positioning, drilling and discharge.

[0023] It should be noted that the material is cylindrical.

[0024] In the example of this application, the drilling assembly includes a first bracket 2 fixedly installed on the side wall of the workbench 1. A drilling device 21 is mounted on the first bracket 2. The drilling device 21 includes a lifting drive device, a rotary motor, and a drill bit. The lifting drive device is fixedly installed on the first bracket 2. The driving end of the lifting drive device is connected to the rotary motor. The rotary motor's rotation drive end is detachably installed with the drill bit. The lifting drive device uses a cylinder, hydraulic cylinder, or electric cylinder, which can control the rotary motor and the drill bit to move up and down. The drill bit is driven by the rotary motor to rotate and realize the drilling process.

[0025] As a preferred example of this utility model, the first bracket 2 of the drilling assembly is fixedly installed on the side wall of the workbench 1 to provide stable support for the drilling device 21 at the top. When the second turntable 15 conveys the material to the area directly below the drilling device 21 and the positioning assembly completes the material positioning, the drilling device 21 receives a control signal and starts to control the drill bit to move downward in the vertical direction to perform drilling operations on the material.

[0026] In the example of this application, the feeding assembly includes a second bracket 22 fixedly installed on one side of the top of the workbench 1. A material cylinder 23 is provided through the top of the second bracket 22. A first electric push rod 24 is fixedly installed on one side of the bottom of the material cylinder 23. The other end of the first electric push rod 24 is movably inserted into the inner cavity of the material cylinder 23 and abuts against the material on the bottom side inside the material cylinder 23.

[0027] As a preferred example of this utility model, the operator first loads a batch of materials into the material cylinder 23 at the top of the second support 22. The materials move towards the bottom of the material cylinder 23 under the action of gravity. When the feeding program is started, the first electric push rod 24 receives the instruction to retract, and its end separates from the material on the bottom side inside the material cylinder 23. The materials move towards the outlet of the material cylinder 23 under the action of gravity, so that the materials fall individually onto the first turntable 11 below.

[0028] In the example of this application, both ends of the material trough 16 are connected and have arc-shaped openings.

[0029] As a preferred example of this utility model, when the material on the first turntable 11 moves to the second turntable 15 under the guidance of the limiting and guiding mechanism, the material first contacts the arc-shaped opening at the inlet end of the trough 16. The smooth curved surface of the arc-shaped opening guides the material to gradually enter the trough 16, avoiding the collision between the material's corners and the straight edge of the trough 16, which would cause jamming. After the material rotates with the second turntable 15 in the trough 16 to the drilling area to complete the processing, the second turntable 15 continues to rotate. Under the action of centrifugal force and the limiting and guiding mechanism, the material smoothly detaches from the arc-shaped opening at the outlet end of the trough 16 and transitions along the arc surface to the subsequent conveying path, ensuring that the material enters and exits the trough 16 smoothly.

[0030] In the example of this application, the limiting and guiding mechanism includes a first outer cover 12 disposed on the outside of the first turntable 11 and a second outer cover 13 disposed on the outside of the second turntable 15. The first outer cover 12 and the second outer cover 13 are both fixedly installed on the workbench 1, and a third outer cover 14 is fixedly connected between the first outer cover 12 and the second outer cover 13.

[0031] As a preferred example of this utility model, the first outer cover 12 surrounds the outside of the first turntable 11, forming a semi-enclosed channel. When the first turntable 11 drives the material to move centrifugally, the first outer cover 12 prevents the material from scattering outward and guides the material to move towards the second turntable 15. The second outer cover 13 surrounds the outside of the second turntable 15 and connects with the first outer cover 12 to form a complete material guiding channel. After the material enters the trough 16 of the second turntable 15, and the third outer cover 14 is installed between the first outer cover 12 and the second outer cover 13, the material can be pulled into the trough 16 of the second turntable 15. The second outer cover 13 restricts the material to move stably in the trough 16 and prevents the material from leaving the trough 16 during the rotation of the second turntable 15.

[0032] In the example of this application, a sloping groove 31 is provided at one end of the side wall of the workbench 1. The sloping groove 31 corresponds to the end of the second outer cover 13, and the cross-section of the sloping groove 31 is triangular.

[0033] As a preferred example of this utility model, after the material completes the drilling operation, it moves to the end of the second outer cover 13 under the guidance of the limiting and guiding mechanism. At this time, the material is freed from the constraint of the limiting and guiding mechanism and directly enters the inclined groove 31 on the side wall of the corresponding workbench 1. Since the cross-section of the inclined groove 31 is triangular and has a certain inclination angle, the material slides automatically down along the inclined surface of the inclined groove 31 under the action of gravity. Without the need for an additional driving device, it can slide out of the workbench 1 from the bottom outlet of the inclined groove 31, completing the discharge process and realizing the automatic collection of processed materials.

[0034] In the example of this application, two motors 3 are fixedly installed at the bottom of the workbench 1. The drive output end of the motor 3 is connected to the transmission shaft. Both transmission shafts pass through the workbench 1 and are fixedly connected to the central shafts of the first turntable 11 and the second turntable 15 respectively.

[0035] As a preferred example of this utility model, after the motor 3 is started, its drive output end drives the transmission shaft to rotate. The two transmission shafts pass through the workbench 1 and are fixedly connected to the central shafts of the first turntable 11 and the second turntable 15, thereby driving the first turntable 11 and the second turntable 15 to rotate.

[0036] In the example of this application, the positioning component includes a limiting groove 32 opened on one side of the second outer cover 13, a pressing block 33 is slidably installed in the limiting groove 32, the inner wall of the pressing block 33 is arc-shaped, the pressing block 33 is connected to the driving end of the second electric push rod 34, and the second electric push rod 34 is installed on the outside of the second outer cover 13.

[0037] As a preferred example of this utility model, when the second turntable 15 conveys the material in the trough 16 to the bottom of the drilling assembly, the second electric push rod 34 starts to extend, pushing the extrusion block 33, which is fixedly connected to it, to slide in the limiting groove 32 of the second outer cover 13. The extrusion block 33 gradually approaches the material. Since the inner wall of the extrusion block 33 is arc-shaped, after it fits against the surface of the material, it continues to apply pressure to clamp and fix the material in the trough 16. During the drilling process, the extrusion block 33 remains in a clamped state to prevent the material from shifting. After the drilling is completed, the second electric push rod 34 retracts, driving the extrusion block 33 to reset in the limiting groove 32, releasing the clamping of the material. The material then enters the subsequent discharge process as the second turntable 15 rotates.

[0038] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
