Abstract
Description
Technical Field
[0001] This utility model relates to the field of parts processing technology, and in particular to a fixture for parts processing. Background Technology
[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for construction or inspection. It is also called a clamp. In a broader sense, any device used to quickly, conveniently and safely install a workpiece in any step of the process can be called a fixture.
[0003] A search revealed a Chinese patent with authorization number CN220218074U, which discloses an adjustable fixture for machining mechanical parts. The fixture includes a fixed base with an internal mounting groove. Two symmetrically spaced limiting grooves are formed on the top of the fixed base. A guide rod is installed inside the mounting groove. Two first movable blocks are symmetrically mounted on the guide rod, and two second movable blocks are symmetrically mounted between the two first movable blocks on the guide rod. Two symmetrically arranged moving blocks are positioned on the top of each of the two second movable blocks. The two moving blocks on the top of each second movable block protrude from the inside of the two limiting grooves outside the fixed base. A gripper is connected to one end of each of the two moving blocks protruding from the fixed base. This invention allows for convenient adjustment of the gripper's clamping force on the workpiece, thereby reducing the probability of damage to the workpiece due to excessive clamping force.
[0004] The adjustable fixture for machining mechanical parts in the aforementioned patent has the following shortcomings: when machining parts, there are multiple processes, such as turning, milling, drilling, cutting, and inspection, all of which require clamping and fixing the parts. After clamping and fixing the parts, the aforementioned device cannot continue to adjust the position of the parts. The parts need to be removed from the fixture and clamped and fixed again with the fixture at the next process position, which is very troublesome. The fixture needs to be adjusted multiple times to install and remove the parts, which affects the overall efficiency and continuity of the machining work. Therefore, it is necessary to design a fixture for machining parts to solve the above problems. Utility Model Content

[0023] In this utility model, a first movable seat 12 is fixedly connected to the bottom of the guide plate 11. A first lead screw nut 13 is threaded through the first movable seat 12 and fixedly connected to the first movable seat 12. A first drive lead screw 14 is threaded through the first lead screw nut 13 and adapted to the first drive lead screw 14. Both ends of the first drive lead screw 14 are fitted with first bearing seats 15. The inner wall of the inner ring of the bearing on the first bearing seat 15 is fixedly connected to the base 1. A first servo motor 19 is provided on one side of the first drive lead screw 14. The output end of the first servo motor 19 is connected to the first drive lead screw 14 through a coupling. A scale 27 is provided on one side of the first movable seat 12 and fixedly connected to the top of the base 1.
[0024] In this utility model, sliding plates 16 are fixedly connected to the bottom of both ends of the guide plate 11. A second guide rod 17 is passed through the sliding plate 16. The sliding plate 16 is slidably connected to the second guide rod 17. The second guide rod 17 is fixedly connected to the base 1. When the guide plate 11 moves, it will drive the sliding plate 16 to move along the second guide rod 17, ensuring the stability of the guide plate 11 when it moves, so that the guide plate 11 can make linear motion.
[0025] In this utility model, a first fixing frame 18 is fixedly connected to the top of the base 1, and a first servo motor 19 is fixedly connected to the first fixing frame 18.
[0026] In this invention, two second bearing seats 21 are fixedly connected to the top of the base 1. The inner walls of the inner rings of the bearings on the two second bearing seats 21 are fixedly connected to the same second drive screw 22. The second drive screw 22 is fitted with a second screw nut 23, and the second drive screw 22 and the second screw nut 23 are compatible. A second movable seat 24 is fixedly connected to the outer wall of the second screw nut 23. The second movable seat 24 is fixedly connected to the bottom of the moving platform 2. A second servo motor 26 is provided on one side of the second drive screw 22. The output end of the second servo motor 26 is connected to the second drive screw 22 through a coupling. The second movable seat 24 can be moved by the second servo motor 26 driving the second drive screw 22 to rotate. The movement of the second movable seat 24 can drive the moving platform 2 to move, which can also drive the parts to move and adjust the position of the parts.
[0027] In this utility model, both ends of the second movable seat 24 are provided with third guide rods 25. The second movable seat 24 is slidably connected to the third guide rods 25. The third guide rods 25 are fixedly connected to the base 1. When the second movable seat 24 moves, it will move along the third guide rods 25, so that the second movable seat 24 can make linear motion and ensure the stability of the second movable seat 24 during the movement process.
[0028] In this utility model, a second fixing frame 20 is fixedly connected to the top of the base 1, and a second servo motor 26 is fixedly connected to the second fixing frame 20.
[0029] Working principle: During use, the parts to be processed are placed on the moving table 2. An external power supply is used. The controller of the external device starts the second servo motor 26. The output of the second servo motor 26 drives the coupling to rotate, which in turn drives the second drive screw 22 to rotate. The second drive screw 22 then moves the second screw nut 23, which in turn moves the second moving seat 24 along the third guide rod 25. The movement of the second moving seat 24 moves the moving table 2, which in turn moves the parts. Simultaneously, the moving table 2 moves the first guide rod 4, which in turn moves the slider 8. The slider 8 then moves the second clamping plate 7 and the fixed shaft 9, which in turn moves the roller 10 along... As the guide plate 11 moves, and the roller 10 continues to move towards the inclined plate of the guide plate 11, the roller 10 will move closer to the second drive screw 22, allowing the slider 8 to move along the first guide rod 4 and the slide groove 3. When the slider 8 moves, it will compress the spring 5, causing the spring 5 to contract. The movement of the slider 8 will also cause the second clamping plate 7 to move closer to the first clamping plate 6. During its movement, the second clamping plate 7 will contact the component, and its continued movement will carry the component along with it, ensuring that both the second clamping plate 7 and the first clamping plate 6 can contact the component, thus clamping and fixing it. When the roller 10 moves to the long straight plate of the guide plate 11, the first clamping plate 6 and the second clamping plate 7 will clamp and fix the component, causing the output end of the second servo motor 26 to rotate and continue driving the movement. The movement of platform 2 allows adjustment of the position of the clamped parts, enabling multiple processing steps to be completed on the same fixture, improving the continuity and efficiency of the overall process. After processing, the output of the second servo motor 26 is reversed, returning platform 2 to its initial position. This causes roller 10 to return to its initial position, and the retracted spring 5 to extend, allowing slider 8 to return to its initial position. The first clamping plate 6 and the second clamping plate 7 no longer clamp and fix the parts, allowing the processed parts to be removed. When it is not necessary to adjust the position of the parts during processing, the first servo motor 19 is started via the external controller. The output of the first servo motor 19 drives the coupling to rotate, which in turn drives the first drive screw 14 to rotate. The drive screw 14 moves the first screw nut 13, which in turn moves the first moving seat 12. The first moving seat 12 then moves the guide plate 11, which moves closer to the second drive screw 22. The guide plate 11 then moves the roller 10, which in turn moves the fixed shaft 9. The fixed shaft 9 then moves the slider 8, which in turn moves the second clamping plate 7 closer to the first clamping plate 6. This clamping action effectively secures the components. Reversing the rotation of the output of the first servo motor 19 moves the guide plate 11 away from the second drive screw 22, causing the retracted spring 5 to unfold again, moving the second clamping plate 7 away from the first clamping plate 6. As the guide plate 11 moves, it causes the sliding plate 16 to move along the second guide rod 17.When it is necessary to adjust the position of parts and clamp and fix parts of different sizes during processing, the first drive screw 14 is rotated to adjust the position of the first moving seat 12. The distance the first moving seat 12 moves is determined by the scale 27. The movement of the first moving seat 12 causes the guide plate 11 to move, thereby adjusting the initial position of the guide plate 11, which in turn adjusts the initial position of the second clamping plate 7, thus enabling the clamping and fixing of parts of different sizes.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
