Description

Technical Field

[0001] This invention relates to the field of precision parts machining technology, and in particular to an automatic positioning and assembly robot for precision parts machining. Background Technology

[0002] In today's industrial manufacturing field, the machining and assembly of precision parts are key links that determine product performance and quality. With the rapid development of technology, the demand for precision parts in various industries is increasing day by day, and more stringent requirements are being placed on the machining accuracy, assembly quality and production efficiency of parts.

[0003] Traditional manual assembly methods have many insurmountable limitations when dealing with precision parts. First, manual operation cannot guarantee high precision. Second, manual assembly is inefficient. Workers are prone to fatigue during long hours of high-intensity assembly work, which leads to a decrease in assembly speed and makes it difficult to meet the needs of large-scale production. In addition, manual assembly is labor-intensive and requires strict skill levels from workers, which increases the company's human resource costs and training difficulties.

[0004] Therefore, this application proposes an automatic positioning and assembly robot for precision parts machining. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned technical problems by proposing an automatic positioning and assembly robot for precision parts processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automated positioning and assembly robot for precision parts machining includes a support plate with four mounting blocks mounted on it. A first piston cylinder is installed through each mounting block, and a first movable piston is movably connected within the first piston cylinder. A drive rod is fixed to the first movable piston, and a guided clamping plate is fixed to the drive rod. The four clamping plates can move synchronously to clamp parts. A mounting frame is mounted on the support plate, with a first guide groove at its upper end. A first slider, driven to move, is slidably connected within the first guide groove. A connecting frame is mounted on the first slider, and a movable frame is fixed to the connecting frame. A second guide groove is provided at the bottom of the movable frame, with a second slider slidably connected within the second guide groove. A lifting and lowering fixed frame is mounted on the bottom of the second slider, and a pneumatic gripper is mounted on the fixed frame. The pneumatic gripper is used to clamp and assemble parts onto the workpiece.

[0007] Preferably, the bottom of the support plate is fixed with four support legs, which are arranged in a rectangular shape, and each of the four support legs has a leather pad fixed to its bottom.

[0008] Preferably, the upper end of the support plate is provided with a cross guide groove, and a guide block is slidably connected in the cross guide groove. The guide block is fixedly connected to the bottom of the clamping plate.

[0009] Preferably, a U-shaped frame is fixed to the bottom of the support plate, a first electric push rod is installed at the bottom of the U-shaped frame, a first connecting rod is fixed to the output end of the first electric push rod, a second piston cylinder is fixed to the bottom of the support plate, a second movable piston is slidably connected inside the second piston cylinder, the first connecting rod is fixedly connected to the bottom of the second movable piston, and the second piston cylinder is connected to the first piston cylinder through a connecting pipe.

[0010] Preferably, a first motor is mounted on the mounting bracket, and a first screw is fixed to the output end of the first motor. The first screw passes through the first slider and is threadedly connected to it. The first screw is rotatably connected to the inner wall of the first guide groove.

[0011] Preferably, a second motor is installed on the movable frame, and a second screw is fixed to the output end of the second motor. The second screw passes through the second slider and is threadedly connected to it. The second screw is rotatably connected to the inner wall of the second guide groove.

[0012] Preferably, a second electric push rod is installed at the bottom of the second slider, and a second connecting rod is fixed to the output end of the second electric push rod. The second connecting rod is fixedly connected to the upper end of the fixing frame.

[0013] Preferably, the guide includes a sleeve fixed to the bottom of the second slider, a guide rod slidably connected inside the sleeve, and the guide rod is fixedly connected to the upper end of the fixing frame.

[0014] Compared with the prior art, the beneficial effects of this invention are as follows: 1. Precise and stable clamping: The parts are clamped by the synchronous movement of four clamping plates, and the pressure inside the four first piston cylinders is the same, which ensures that the clamping force of the clamping plates is consistent. This enables automatic centering and clamping of parts such as pump bodies, effectively avoiding clamping deviations, providing a precise benchmark for subsequent assembly work, and improving assembly accuracy.

[0015] 2. Flexible multi-directional movement: Flexible X-axis and Y-axis adjustment: During the assembly stage, the first motor drives the first screw to rotate, causing the first slider to slide along the X-axis in the first guide groove, thus moving the mounting frame and the moving frame along the X-axis. The second motor drives the second screw to rotate, causing the second slider to slide along the Y-axis in the second guide groove, thus moving the gripper and the assembly along the Y-axis. This design allows the assembly to be flexibly positioned on the horizontal plane, meeting the needs of different assembly positions and greatly improving the robot's applicability. Precise vertical control: The second electric push rod can drive the fixed frame to move up and down, thereby driving the gripper and the assembly to move precisely in the vertical direction. Combined with the guiding effect of the sleeve and guide rod in the guide component, it ensures that the fixed frame is stable and reliable during the up and down movement, ensuring that the assembly can be accurately moved to the appropriate position above the part for assembly, effectively improving the assembly accuracy and quality.

[0016] 3. Highly efficient and automated operation: The entire clamping process is completed automatically through the cooperation of the first electric push rod, hydraulic oil and piston cylinder, without the need for manual intervention. This achieves automatic positioning and clamping of parts, greatly improving production efficiency and reducing errors and labor intensity caused by manual operation.

[0017] 4. Integrated Assembly Process: From clamping the components to their horizontal and vertical movement, and finally to assembly, the entire process is automated and integrated. The components work collaboratively and smoothly, enabling the rapid and accurate assembly of precision parts, further improving production efficiency and meeting the demands of modern industrial production for efficient and precise assembly.

[0018] In summary, this invention enables automatic centering and clamping of parts, ensuring consistent clamping force and improving assembly accuracy; it allows for flexible multi-axis movement, accurately completing the assembly of parts with efficiency far exceeding that of manual labor; it reduces the labor intensity of workers, decreases reliance on worker skills, saves enterprise manpower and training costs, meets the needs of large-scale production, and effectively guarantees the quality and efficiency of precision parts processing and assembly.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Reference Figures 1-5 An automatic positioning and assembly robot for precision parts processing includes a support plate 1. Four support legs 2 are fixed to the bottom of the support plate 1 by welding. The four support legs 2 are arranged in a rectangular shape, and each of the four support legs 2 has a leather pad fixed to its bottom, so as to provide stable support for the support plate 1.

[0023] Four mounting blocks 11 are installed on the support plate 1. A first piston cylinder 12 is installed through the mounting blocks 11. A first movable piston 31 is movably connected inside the first piston cylinder 12. A drive rod 32 is fixed on the first movable piston 31. A guide plate 14 is fixed on the drive rod 32. A cross guide groove 29 is provided at the upper end of the support plate 1. A guide block 30 is slidably connected inside the cross guide groove 29. The guide block 30 is fixedly connected to the bottom of the clamping plate 14. The clamping plate 14 can be guided by the cross guide groove 29 and the guide block 30, thereby ensuring its stable movement.

[0024] Four clamping plates 14 can move synchronously to clamp the parts. A U-shaped frame 15 is fixed to the bottom of the support plate 1. A first electric push rod 16 is installed at the bottom of the U-shaped frame 15. A first connecting rod 17 is fixed to the output end of the first electric push rod 16. A second piston cylinder 18 is fixed to the bottom of the support plate 1. A second moving piston 19 is slidably connected inside the second piston cylinder 18. The first connecting rod 17 is fixedly connected to the bottom of the second moving piston 19. The second piston cylinder 18 is connected to the first piston cylinder 12 through a connecting pipe 13.

[0025] Further explanation: The first piston cylinder 12 and the second piston cylinder 18 are filled with hydraulic oil. The first electric push rod 16 can drive the first connecting rod 17 and the second moving piston 19 to move. The movement of the second moving piston 19 can squeeze the hydraulic oil in the second piston cylinder 18 into the four first piston cylinders 12 through the connecting pipe 13. The increased pressure in the first piston cylinder 12 can drive the drive rod 32 and the first moving piston 31 to move. The movement of the drive rod 32 drives the clamping plate 14 to move, thereby clamping the parts and realizing automatic positioning of the parts.

[0026] Because the pressure is evenly distributed in the four first piston cylinders 12, the clamping force of the clamping plate 14 is the same. For clamping the transmission housing, such as when a gear is installed in the pump body, the clamping plate 14 can clamp the pump body and clamp it in the center.

[0027] A mounting bracket 3 is installed on the support plate 1. The upper end of the mounting bracket 3 is provided with a first guide groove 4. A first slider 6, which is driven to move, is slidably connected in the first guide groove 4. A connecting bracket 8 is installed on the first slider 6. A first motor 7 is installed on the mounting bracket 3. A first screw 5 is fixed to the output end of the first motor 7. The first screw 5 passes through the first slider 6 and is threadedly connected to it. The first screw 5 is rotatably connected to the inner wall of the first guide groove 4. When the first motor 7 works, it drives the first screw 5 to rotate. The rotation of the first screw 5 causes the first slider 6 to move in the first guide groove 4, thereby driving the connecting bracket 8 to move.

[0028] A movable frame 9 is fixed on the connecting frame 8. The movement of the connecting frame 8 drives the movable frame 9 to move. The bottom of the movable frame 9 is provided with a second guide groove 21. A second slider 20 is slidably connected in the second guide groove 21. A lifting fixed frame 27 is installed on the bottom of the second slider 20. A second motor 10 is installed on the movable frame 9. A second screw 22 is fixed to the output end of the second motor 10. The second screw 22 passes through the second slider 20 and is threadedly connected to it. The second screw 22 is rotatably connected to the inner wall of the second guide groove 21. The operation of the second motor 10 drives the second screw 22 to rotate. The rotation of the second screw 22 causes the second slider 20 to move. The movement of the second slider 20 drives the second electric push rod 23 to move.

[0029] A pneumatic gripper 28 is mounted on the fixed frame 27. The pneumatic gripper 28 is used to clamp the assembly and assemble it onto the part. A second electric push rod 23 is mounted on the bottom of the second slider 20. A second connecting rod 26 is fixed to the output end of the second electric push rod 23. The second connecting rod 26 is fixedly connected to the upper end of the fixed frame 27. A guide component is also included. The guide component includes a sleeve 24 fixed to the bottom of the second slider 20. A guide rod 25 is slidably connected inside the sleeve 24. The guide rod 25 is fixedly connected to the upper end of the fixed frame 27. This ensures that the fixed frame 27 moves stably up and down.

[0030] The second electric push rod 23 drives the fixed frame 27 to move down, which in turn drives the pneumatic gripper 28 to move down. The pneumatic gripper 28 clamps the parts to be assembled. The first slider 6 and the second slider 20 can move the clamped parts. The assembly of the parts can be achieved by the second electric push rod 23 driving the pneumatic gripper 28 to move down.

[0031] The work process is as follows: Part clamping stage: At the bottom of the support plate 1, the first electric push rod 16 installed on the U-shaped frame 15 starts working, and its output end drives the first connecting rod 17 to move upward. The first connecting rod 17 is connected to the bottom of the second moving piston 19 fixed in the second piston cylinder 18, thereby pushing the second moving piston 19 to slide upward.

[0032] Since the second piston cylinder 18 is connected to the four first piston cylinders 12 through the connecting pipe 13, and the first piston cylinders 12 and the second piston cylinder 18 are filled with hydraulic oil, when the second moving piston 19 moves upward, it will squeeze the hydraulic oil in the second piston cylinder 18 into the four first piston cylinders 12 through the connecting pipe 13.

[0033] As hydraulic oil enters the first piston cylinder 12, the pressure inside the first piston cylinder 12 increases, pushing the first moving piston 31 to move. The drive rod 32 fixed on the first moving piston 31 moves accordingly, and the other end of the drive rod 32 is connected to the clamping plate 14.

[0034] The upper end of the support plate 1 is provided with a cross guide groove 29. The guide block 30 fixed at the bottom of the clamping plate 14 slides in the cross guide groove 29, which guides the clamping plate 14 and ensures its stable movement. Under the action of hydraulic oil pressure, the four clamping plates 14 move synchronously towards the center to clamp the parts placed on the support plate 1. Since the pressure inside the four first piston cylinders 12 is the same, the clamping force of the clamping plates 14 is consistent, which can realize the automatic centering and clamping of parts such as pump bodies.

[0035] Assembly clamping stage: The second electric push rod 23 installed on the movable frame 9 is activated, and its output end drives the second connecting rod 26 to move downward. The second connecting rod 26 is connected to the upper end of the fixed frame 27. The guide rod 25 fixed at the upper end of the fixed frame 27 slides in the sleeve 24 to provide guidance for the movement of the fixed frame 27 and ensure its stable up and down movement.

[0036] The fixed frame 27 is driven to move down by the second electric push rod 23, which in turn drives the pneumatic gripper 28 fixed on the fixed frame 27 to move down to the assembly position, and the pneumatic gripper 28 works to clamp the assembly.

[0037] Assembly stage of components: Horizontal movement: X-axis direction: A first motor 7 is installed on the mounting bracket 3 on the support plate 1. When the first motor 7 is started, its output end drives the first screw 5 to rotate. The first screw 5 passes through the first slider 6 and is threadedly connected to it. The first screw 5 is rotatably connected to the inner wall of the first guide groove 4 at the upper end of the mounting bracket 3. When the first screw 5 rotates, the first slider 6 slides in the first guide groove 4 along the X-axis direction. A connecting bracket 8 is installed on the first slider 6. The connecting bracket 8 moves with the first slider 6, thereby driving the moving bracket 9 to move along the X-axis direction.

[0038] Y-axis direction: A second motor 10 is installed on the moving frame 9. When the second motor 10 is started, its output end drives the second screw 22 to rotate. The second screw 22 passes through the second slider 20 and is threadedly connected to it. The second screw 22 is rotatably connected to the inner wall of the second guide groove 21 at the bottom of the moving frame 9. When the second screw 22 rotates, the second slider 20 slides in the second guide groove 21 along the Y-axis direction. The bottom of the second slider 20 is equipped with a second electric push rod 23, a fixed frame 27, and a pneumatic gripper 28 for clamping the assembly, thereby driving the assembly to move along the Y-axis direction.

[0039] Vertical movement: After the assembly moves to a suitable position above the part, the second electric push rod 23 is activated again, driving the fixing frame 27 to move down, which in turn drives the pneumatic gripper 28 and the assembly to move down, accurately assembling the assembly onto the clamped part, thus completing the assembly of the precision part.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
