Description

Technical Field

[0001] This utility model belongs to the field of machining technology, and in particular relates to a quick-change fixture for multi-process machining. Background Technology

[0002] Machining refers to the process of cutting and shaping metallic or non-metallic materials through physical processing methods such as turning, milling, planing, grinding, and drilling to change their shape, size, or properties, and ultimately manufacture parts or products that meet design requirements. During multi-stage machining, appropriate fixtures are often used to ensure the stability of the parts and the machining accuracy.

[0003] The existing utility model with authorization announcement number CN216542061U discloses a multi-process fixture for CNC machining of turbine machinery. The setting of the adjusting rotating plate facilitates rotation adjustment by fixing it to the top center of the supporting fixed plate with bearings and fixing it with pins. It also facilitates the flipping plate of the supporting plate to be flipped and fixed by the fixed shaft, which solves the problem of not being able to perform rotation adjustment machining and disassembly maintenance. The setting of the supporting flipping plate facilitates the flipping adjustment and fixing by fixing it to the top of the adjusting rotating plate by the fixed shaft, and facilitates synchronous rotation adjustment with the adjusting rotating plate. It also facilitates the threaded clamping rod to drive the clamping plate to clamp the workpiece by the threaded installation, which solves the problem of only being able to perform one process operation after clamping.

[0004] While the above technical solution enables rotational adjustment and disassembly maintenance, and facilitates multi-process processing after rotational adjustment, the clamping force of the clamping structure requires manual adjustment. It lacks an efficient clamping structure that can adaptively and quickly clamp parts with appropriate force, resulting in low efficiency of clamping force adjustment and thus affecting the processing efficiency of subsequent parts in multiple processes.

[0005] To address these issues, we propose a quick-change fixture for multi-process machining. Utility Model Content

[0006] The purpose of this invention is to solve the problem that the existing technology lacks an efficient clamping structure that can quickly and adaptively clamp parts with appropriate force, resulting in low efficiency of clamping force adjustment, which affects the processing efficiency of subsequent multi-process parts. Therefore, this invention proposes a quick-change fixture for multi-process processing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A quick-change fixture for multi-process machining includes a base, a button controller fixedly connected to the left side of the base, a servo motor fixedly connected to the inner wall of the base, a turntable disposed above the base, a rotating rod fixedly connected to the output end of the servo motor, a clamping seat fixedly connected to the upper surface of the turntable, a hydraulic rod fixedly connected to the inner wall of the clamping seat, a top plate fixedly connected to the telescopic end of the hydraulic rod, a pressure sensor fixedly connected to the right side of the top plate, a clamping plate disposed on the right side of the top plate, and four guide rods fixedly connected to the left side of the clamping plate.

[0009] Preferably, the top end of the rotating rod is fixedly connected to the bottom surface of the turntable, the right side of the pressure sensor is in contact with the left side of the clamping plate, the outer surface of each guide rod is slidably connected to the inside of the top plate, an electric push rod is fixedly connected to the inner wall of the base, a lifting plate is fixedly connected to the telescopic end of the electric push rod, the upper surface of the lifting plate is in contact with the bottom surface of the turntable, and the servo motor, hydraulic rod and pressure sensor are all electrically connected to the button controller through wires.

[0010] Preferably, the upper surface of the lifting plate is fixedly connected to two positioning posts, and the upper surface of the turntable is provided with several identical positioning holes, with the outer surface of each positioning post in contact with the inner wall of the positioning hole.

[0011] Preferably, mounting plates are fixedly connected to both the front and back of the base, and each mounting plate has several identical mounting holes on its upper surface.

[0012] Preferably, an auxiliary bearing is fixedly connected to the inner wall of the base, and the inner ring of the auxiliary bearing is fixedly connected to the outer surface of the rotating rod.

[0013] Preferably, the bottom surface of the top plate is fixedly connected to two limiting sliders, and the outer surface of each limiting slider is slidably connected to the inside of the clamp.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] Through the coordinated operation of the base, button controller, servo motor, rotating rod, turntable, clamp, hydraulic rod, top plate, clamping plate, guide rod, and pressure sensor, the button controller can communicate with external control structures. The button controller can energize the servo motor to control the rotating rod, causing the turntable and clamp to rotate at different angles, thereby changing the position of the clamped part within the clamp. The button controller can control the hydraulic rod to gradually extend, and as the clamping plate and clamp gradually tighten the part, the pressure sensor senses that the pressure on the clamping plate gradually increases until it reaches the preset pressure value of the button controller. At this point, the button controller stops the hydraulic rod from extending, achieving efficient and adaptive clamping of the part. This avoids the problem of low clamping force adjustment efficiency due to the lack of an efficient clamping structure that can adaptively and quickly clamp parts with appropriate force, thus affecting the processing efficiency of subsequent multi-process parts.

Detailed Implementation

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

[0022] Reference Figures 1-4This embodiment provides a quick-change fixture for multi-process machining. The quick-change fixture includes a base 1, and a button controller 2 is fixedly connected to the left side of the base 1. The button controller 2 adopts an MCU, which can be an Arduino series. It is small in size, low in cost and low in power consumption, and is suitable for miniaturization and embedded applications. It can control multiple components through programming. It can be connected to the control terminal of each electrical component through digital output pins and control the power of each component through analog output pins. Specific control logic and timing can be implemented by writing code. A servo motor 3 is fixedly connected to the inner wall of the base 1, and an electric push rod 14 is fixedly connected to the inner wall of the base 1. A lifting plate 15 is fixedly connected to the telescopic end of the electric push rod 14. The upper surface of the lifting plate 15 is in contact with the bottom surface of the turntable 5. By setting the electric push rod 14, it can control the lifting and lowering of the lifting plate 15 by telescopic extension after being energized. By setting the lifting plate 15, the height position of the positioning structure on it can be controlled.

[0023] A turntable 5 is mounted on top of the base 1. A rotating rod 4 is fixedly connected to the output end of the servo motor 3. The top of the rotating rod 4 is fixedly connected to the bottom surface of the turntable 5. Two positioning posts 16 are fixedly connected to the upper surface of the lifting plate 15. Several identical positioning holes 17 are opened on the upper surface of the turntable 5. The outer surface of each positioning post 16 is in contact with the inner wall of the positioning hole 17. By setting the positioning posts 16, the turntable 5 can be docked with the positioning hole 17 after rotating to the appropriate position, thereby increasing the stability of the parts on the turntable 5.

[0024] A clamping seat 6 is fixedly connected to the upper surface of the turntable 5. A hydraulic rod 7 is fixedly connected to the inner wall of the clamping seat 6. Mounting plates 12 are fixedly connected to both the front and back of the base 1. Several identical mounting holes 13 are opened on the upper surface of each mounting plate 12. By setting the mounting holes 13, the mounting plate 12 can be fixed in the processing environment of each process in conjunction with the external positioning structure, thereby fixing the entire fixture structure.

[0025] The telescopic end of the hydraulic rod 7 is fixedly connected to the top plate 8. The right side of the top plate 8 is fixedly connected to the pressure sensor 11. The servo motor 3, the hydraulic rod 7, and the pressure sensor 11 are all electrically connected to the button controller 2 through wires. The inner wall of the base 1 is fixedly connected to the auxiliary bearing 19. The inner ring of the auxiliary bearing 19 is fixedly connected to the outer surface of the rotating rod 4. By setting the auxiliary bearing 19, the base 1 and the rotating rod 4 can be connected, thereby increasing the smoothness of the rotation of the rotating rod 4.

[0026] A clamping plate 9 is provided on the right side of the top plate 8. The right side of the pressure sensor 11 is in contact with the left side of the clamping plate 9. Four guide rods 10 are fixedly connected to the left side of the clamping plate 9. The outer surface of each guide rod 10 is slidably connected to the inside of the top plate 8. Two limiting sliders 18 are fixedly connected to the bottom surface of the top plate 8. The outer surface of each limiting slider 18 is slidably connected to the inside of the clamping seat 6. By setting the limiting sliders 18, the top plate 8 can slide left and right inside the clamping seat 6, thereby increasing the directional stability of the top plate 8 in the left and right movement within the clamping seat 6.

[0027] The working principle of this utility model is as follows: During use, an external bolt or other fixing structure, along with multiple mounting holes 13, is used to fix the mounting plate 12 in the middle of multiple processes forming a circle. The button controller 2 communicates with the external control structure. When it is necessary to adjust the work position angle of the part inside the clamp 6, the external control mechanism controls the servo motor 3 to rotate the rotating rod 4 and turntable 5 via the button controller 2. After rotating to a suitable angle, the button controller 2 controls the electric push rod 14 to extend, allowing the two positioning pins 16 to be inserted into the two positioning holes 17 respectively, thus fixing the work position of the part inside the clamp 6. When the part to be processed is placed into the clamp 6, the external control structure controls the servo motor 3 to rotate via the button controller 2. As the hydraulic rod 7 gradually extends, and the clamping plate 9 and the clamping seat 6 gradually clamp the part, the pressure sensor 11 senses that the pressure of the clamping plate 9 will gradually increase until the pressure value reaches the preset pressure value of the button controller 2. At this point, the button controller 2 controls the hydraulic rod 7 to stop extending, thus achieving efficient adaptive clamping of the part. The preset pressure value of the button controller 2 can be flexibly set and adjusted according to the hardness and processing characteristics of different parts. The design of the quick-change fixture for multi-process processing effectively solves the problem that the lack of an efficient clamping structure that can adaptively and quickly clamp parts with appropriate force leads to low efficiency in clamping force adjustment, which affects the processing efficiency of subsequent multi-process parts.
