Description

Technical Field

[0001] This invention relates to the field of industrial robot technology, and in particular to an industrial robot for drilling pins. Background Technology

[0002] The radial oil hole on the sidewall of the pin serves the core function of lubrication and pressure balance: it connects the axial lubrication channels inside the pin with the external friction surfaces (such as the inner wall of the bushing), forming a continuous lubricating oil film to reduce wear. Simultaneously, under high-speed or hydraulic conditions, it helps balance internal and external pressures and remove impurities. The commonly used term "pin drill" is not a standard tool name; in this context, it often refers to a deep-hole drill (such as a gun drill) used to machine radial oil holes with large diameters and precise positioning requirements, or generally refers to the drilling and milling process of this oil hole. Therefore, this hole is a crucial lubrication channel ensuring the long-term reliable operation of the pin, and its machining typically requires specialized deep-hole drilling technology. However, existing pin drilling robots' feeding mechanisms can only transport pins of a specified diameter. Limited by the rigid structure of the feeding components, a new feeding mechanism is needed when transporting pins of different diameters, resulting in low work efficiency. Summary of the Invention

Detailed Implementation

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] Example 1: Reference Figures 1-9 An industrial robot for drilling pins includes: a base 1, on which a material distribution component 2, a drilling component 3, and an unloading component 4 are connected. The output end of the drilling component 3 faces the material distribution component 2, and the output end of the unloading component 4 faces the unloading guide rail 5 on the base 1. Two parallel plates 6 are longitudinally slidably connected to the base 1. The bottom of the plates 6 contacts and engages with the material distribution component 2. Two guide rails 7 are connected to one plate 6, and two guide rails 8 are slidably connected to the other plate 6. The guide rails 7 and the guide rails 8 are arranged opposite to each other. The mounting plate 9 of the guide rails 8 is connected to the other plate 6 by a limiting spring 10.

[0019] The principles and beneficial effects of the above scheme are as follows: The material distribution component 2 is used to transport the pins from the guide rail 7 and the second guide rail 8. When the pin is transported to the bottom of the drilling component 3 through the material distribution component 2, the drilling component 3 begins to drill the pin. After the drilling is completed, the unloading component 4 is activated to push the processed pin onto the unloading guide rail 5. At the same time, the material distribution component 2 moves in the opposite direction to transport the new pin to be processed to the bottom of the drilling component 3 for processing. When the pin is transported to the material distribution component 2, the guide rail 7 and the second guide rail 8 cooperate to guide the pin from top to bottom. When the diameter of the pin increases, the second guide rail 8 moves away from the plate 6. The movement of the mounting plate 9 causes the limit spring 10 to be stretched. When the diameter of the pin decreases, the length of the limit spring 10 decreases, and the mounting plate 9 and the second guide rail 8 move towards the plate 6. The device is equipped with two movable guide rails 2 8. The elastic force of the limit spring 10 restricts the guide rail 2 8 to always clamp the conveyed pin with the guide rail 7 opposite it. It can convey pins of different diameters, avoids changing the material conveying mechanism during processing, and improves processing efficiency.

[0020] Example 2: Reference Figures 1-9 Both guide rail 7 and guide rail 8 have a chamfer 11 at the top.

[0021] The principles and beneficial effects of the above scheme are as follows: The chamfer 11 at the top of guide rail 7 and guide rail 8 forms a smooth transition guide surface. When the pin enters the clamping channel formed by the guide rail from the feeding position, the chamfer 11 can effectively guide the pin to slide smoothly into the gap between the two guide rails, avoiding jamming or surface scratches caused by hard collision between the pin end and the right-angle edge of the guide rail. At the same time, the chamfer 11 provides progressive contact when the pin diameter changes. With the elastic adjustment of the limit spring 10, pins of different diameters can smoothly transition to a stable conveying position. This structure not only improves the smoothness of pin conveying and positioning accuracy, but also reduces the equipment adjustment time caused by frequent changes in pin specifications, further improving the continuous operation capability and equipment adaptability of the production line.

[0022] Example 3: Reference Figures 1-9 The drilling component 3 includes: a longitudinal slide rail 12, which is connected to a horizontal moving component. A motor 13 is slidably connected to the longitudinal slide rail 12. The top end of the motor 13 is connected to the bottom end of a spring 14, and the top end of the spring 14 is connected to the top end of the longitudinal slide rail 12. The output end of the motor 13 facing the material distribution component 2 is connected to the drill bit 15.

[0023] The horizontal moving component includes: a fixed block 17, which is connected to the base 1. The fixed block 17 is slidably connected to the sliding plate 16. The fixed block 17 is connected to the end of the push rod 19 through a spring 18. The push rod 19 is connected to the sliding plate 16. The other end of the push rod 19 is in contact with the material distribution component 2. The sliding plate 16 is connected to the longitudinal slide rail 12.

[0024] The principles and beneficial effects of the above scheme are as follows: During drilling, after the material distribution component 2 moves the pin into position, it simultaneously drives the sliding plate 16 to slide against the fixed block 17 via the push rod 19. The spring 18 is compressed, and the movement of the sliding plate 16 drives the longitudinal slide rail 12 to move. When drilling is required, the motor 13 slides downward along the longitudinal slide rail 12, and the spring 14 is stretched. The downward movement of the motor 13 can be achieved by installing a cylinder element on the longitudinal slide rail 12 and connecting the output end of the cylinder element to the motor 13. After the motor 13 starts and drives the drill bit 15 to rotate, it begins to drill the pin. After drilling is completed, the output end of the cylinder element moves upward, driving the motor 13 to move upward, preparing for the next operation.

[0025] Example 4: Reference Figures 1-9 The unloading component 4 includes a cylinder 20 and a push plate 21. The cylinder 20 is connected to the sliding plate 16. The output end of the cylinder 20 is connected to the end of the push plate 21. The other end of the push plate 21 is set towards the unloading guide rail 5.

[0026] The principles and beneficial effects of the above scheme are as follows: After the pin drilling process is completed, the output end of the cylinder 20 on the sliding plate 16 drives the push plate 21 to move towards the material distribution component 2, thereby applying external force to the processed pin and causing it to move towards the material guide rail 5 to unload. Integrating the unloading component 4 on the sliding plate 16 has the advantage of compact structure, and the unloading action can correspond to the horizontal movement of the drilling component, simplifying the overall layout and control system.

[0027] Example 5: Reference Figures 1-9 The material distribution component 2 includes: cylinder 22, the output end of cylinder 22 on the base 1 is connected to the connecting plate, the connecting plate is fixed between two slide plates 23, the slide plates 23 are slidably connected to the base 1, the side wall of the slide plate 23 is slidably connected to the longitudinal slide plate 24, the output end of the motor 25 on the connecting plate is connected to the screw 26, the screw 26 is connected to the guide mechanism 27, the guide mechanism 27 is in contact with the bottom of the longitudinal slide plate 24, a tension spring 28 is connected between the longitudinal slide plate 24 and the slide plate 23, and the top of the longitudinal slide plate 24 is in contact with the bottom of the plate body 6.

[0028] The principles and beneficial effects of the above scheme are as follows: When the diameter of the pin increases, the longitudinal slide plate 24 of the slide plate 23 moves upward and the tension spring 28 extends. When the diameter of the pin decreases, the longitudinal slide plate 24 of the slide plate 23 moves downward and the tension spring 28 shortens. The upward or downward movement of the longitudinal slide plate 24 is controlled by the guide mechanism 27. When the motor 25 starts, the rotation of the screw 26 can control the longitudinal slide plate 24 to move upward through the guide mechanism 27. The reverse rotation of the screw 26 can control the longitudinal slide plate 24 to move downward through the guide mechanism 27.

[0029] Example 6: Reference Figures 1-9 The guiding mechanism 27 includes: a screw block 29, the screw rod 26 is threadedly connected to the screw block 29, both ends of the screw block 29 are slidably connected in a groove 31, the groove 31 is opened through the slide plate 23, the end of the screw block 29 is connected to the end of the connecting piece 30, the guide post 33 of the connecting piece 30 is in contact with the inclined surface 35, the inclined surface 35 is set towards the cylinder 22, and the inclined surface 35 is opened on the guide block 34 of the longitudinal slide plate 24.

[0030] The end of the guide plate 32 away from the longitudinal slide plate 24 is longitudinally slidably connected to a lifting plate 36. The lifting plate 36 is connected to the guide plate 32 through a spring 37. The bottom of the guide block 2 of the lifting plate 36 is provided with an inclined surface 38. The inclined surface 38 is set away from the inclined surface 35 and slides with the guide post 39. The guide post 39 is connected to the mounting post 41 through a connecting plate 40. The mounting post 41 slides with the guide groove 42 of the guide plate 32 and is connected to the slide plate 23.

[0031] The principles and beneficial effects of the above scheme are as follows: With the sliding engagement of the groove 31 and the connecting piece 30, the rotation of the screw 26 can drive the screw block 29 to move, thereby moving the connecting piece 30 and the guide piece 32, and the guide post 33 moves synchronously. Through frictional engagement with the inclined surface 35 facing the cylinder 22, the guide block 34 and the longitudinal slide plate 24 move upward. The reverse rotation of screw 26 can drive screw block 29 to move in the opposite direction, thereby causing connecting piece 30 to move in the opposite direction. Guide post 33 and guide piece 32 move in the opposite direction synchronously. Guide block 34 and longitudinal slide plate 24 move downward through frictional engagement with inclined surface 35 facing cylinder 22. Because a tension spring 28 is provided between the longitudinal slide plate 24 and the slide plate 23, the tension spring 28 can not only drive the longitudinal slide plate 24 to return to its original position on the slide plate 23.

[0032] As the longitudinal slide plate 24 moves upward, the guide post 39, which remains stationary on the slide plate 23 through the mounting post 41 and the connecting plate 40, slides in contact with the inclined surface 38 away from the cylinder 22. Under the guidance of the moving guide plate 32, the lifting plate 36 moves upward, and the spring 37 is stretched. The downward movement of the longitudinal sliding plate 24 is achieved through the reverse sliding engagement between the mounting column 41 and the inclined plane 38. Under the guidance of the moving guide plate 32, the lifting plate 36 moves downward, and the spring 37 is shortened. The longitudinal slide plate 24 and the lifting plate 36 are raised and lowered synchronously, and the distance between the lifting plate 36 and the longitudinal slide plate 24 is increased or decreased. Furthermore, the adjustable lifting plate 36 and the longitudinal slide plate 24 are adjusted synchronously with the rising or falling plate body 6 and the guide rails 7 and 8 inside it. In addition, the top of the slide plate 23 allows pins of different diameters to be stored and clamped by the material distribution component 2. The linkage between different components in the device is fully utilized, and the autonomous adjustment capability of the device is improved.

[0033] Example 7: Reference Figures 1-9 The end of the longitudinal slide plate 24 is connected to the clamping plate 43, and the end of the lifting plate 36 is connected to the clamping plate 44. The clamping plates 43 and 44, which are arranged opposite to each other, form a U-shaped clamping groove 45 with the top of the slide plate 23. The push plate 21 is set towards the U-shaped clamping groove 45. A clamping plate 46 is set above the U-shaped clamping groove 45. The clamping plate 46 is slidably connected to the longitudinal slide rail 12. The screw block 47 of the clamping plate 46 is threadedly connected to the screw rod 48. The screw rod 48 is connected to the output end of the motor 49. The motor 49 is connected to the longitudinal slide rail 12.

[0034] The other end of the push rod 19 is in contact with the baffle 50, and the baffle 50 is connected to the other end of the lifting plate 36.

[0035] The principles and beneficial effects of the above scheme are as follows: While the material distribution component 2 stores and clamps pins of different diameters, the clamping plate 43 and clamping plate 44 form a U-shaped clamping groove 45, which increases the contact area between the material distribution component 2 and the pins, further improving the stability of the mechanism during clamping and preventing the pins from shifting during drilling. When the material distribution component 2 moves towards the sliding plate 16, the contact between the baffle 50 and the other end of the push rod 19 can drive the sliding plate 16 to move synchronously. The sliding plate 16 is slidably connected to the fixed block 17 through the limiting groove, so it will not continue to move after it has moved into place. The motor 13 and cylinder 20 move along with the sliding plate 16. Once the pin is in place, drilling begins. To further increase stability during drilling, a second motor 49 is connected to the longitudinal slide rail 12. The second motor 49 drives the second screw 48 to rotate forward, which in turn moves the second screw block 47 and the third clamping plate 46 downward, applying pressure to the top of the pin to further increase stability during drilling and ensure machining accuracy. The second motor 49 drives the second screw 48 to rotate in reverse, which in turn moves the second screw block 47 and the third clamping plate 46 upward, facilitating rapid unloading after the pusher plate 21 is started. When the material distribution component 2 is reset, the sliding plate 16 is reset synchronously. The U-shaped clamping groove 45 can be adjusted based on the actual pin diameter to increase the practicality of the device.

[0036] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
