Technical Field

[0001] This utility model relates to the field of CNC lathe technology, and in particular to a clamping fixture for a square product CNC lathe. Background Technology

[0002] A square-shaped CNC lathe is a type of lathe capable of machining square workpieces. Often called a square lathe or multi-functional lathe, it not only has the ability to machine round workpieces but also square, rectangular, and other irregularly shaped workpieces. Square lathes hold an important position in the machining field and are widely used in various industrial sectors. They possess the following characteristics: High machining accuracy: Equipped with high-precision cutting tools and fixtures to ensure machining accuracy; High efficiency: High adaptability, capable of machining workpieces of various shapes to meet different production needs; High degree of automation: Reduces the labor intensity of operators and improves production efficiency. Applications of square lathes include: Mechanical manufacturing: Used for machining key components such as bearing seats and housings; Automotive parts processing: Used for machining complex-shaped workpieces such as engine blocks and gearbox housings; Aerospace: In these fields, the demand for square workpieces is high, and square lathes play a crucial role. CNC lathe clamping fixtures refer to devices used to position and clamp workpieces on the machine tool or in fixtures during CNC lathe machining. Their main function is to ensure that the workpiece maintains the correct position during machining, preventing displacement under cutting forces, thereby ensuring machining accuracy and efficiency.

[0003] When a worker needs to process a square workpiece, the worker places the square workpiece on a clamping fixture so that the clamping workpiece can be held in place. However, existing clamping fixtures may become unstable in holding square workpieces due to thread damage during use. This causes the CNC machine tool to produce large deviations due to workpiece shaking during processing, which in turn leads to a reduction in product quality. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of reduced product quality in existing technologies, and to propose a clamping fixture for a square product CNC lathe.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a clamping fixture for a square product CNC lathe, comprising a main sleeve, a placement opening, and a replacement device. The placement opening is located on the surface of the main sleeve, and the replacement device is disposed on the surface of the main sleeve. The replacement device includes a placement groove located on the surface of the main sleeve. A support frame is placed on the surface of the placement groove, and placement frames are fixedly connected to both ends of the support frame. The placement frames are placed on the surface of the placement groove. A threaded ring is fixedly connected to the surface of the support frame, and the threaded ring is located above the placement opening. A threaded rod is threadedly connected to the inner surface of the threaded ring. Support blocks are fixedly connected to the surfaces on both sides of the main sleeve. Limiting rods are threadedly connected to the inner surfaces of the support blocks, and the limiting rods are inserted into the inner surfaces of the placement frames. A guide groove is provided on the surface of the main sleeve, and a slider is slidably connected to the surface of the guide groove. A pressure block is fixedly connected between two sliders, and the pressure block is slidably connected to the surface of the main sleeve. Threaded holes are provided on the surfaces on both sides of the main sleeve, and the limiting rods are threadedly connected to the surfaces of the threaded holes. The threaded holes can cooperate with the main sleeve to restrict the placement frames.

[0006] Preferably, the surface of the pressure block is provided with a protective device, the protective device including a built-in groove, the built-in groove being formed on the surface of the pressure block, the built-in groove being able to cooperate with the pressure block to achieve the purpose of guiding the push plate.

A support frame 33 is placed on the surface of the placement groove 34. Placement frames 38 are fixedly connected to both ends of the support frame 33. The placement frames 38 are placed on the surface of the placement groove 34. A threaded ring 32 is fixedly connected to the surface of the support frame 33. The threaded ring 32 is located above the placement opening 2. A threaded rod 31 is threadedly connected to the inner surface of the threaded ring 32. Support blocks 37 are fixedly connected to the surfaces on both sides of the main sleeve 1. Limiting rods 36 are threadedly connected to the inner surface of the support blocks 37. The limiting rods 36 are inserted into the inner surface of the placement frames 38. A guide groove 310 is formed on the surface of the main sleeve 1. A slider 39 is slidably connected to the surface of the guide groove 310. A pressure block 311 is fixedly connected between the two sliders 39. The pressure block 311 is slidably connected to the surface of the main sleeve 1.

[0020] Specifically, threaded holes 35 are provided on the surfaces of both sides of the main sleeve 1. The limiting rod 36 is threadedly connected to the surface of the threaded hole 35. The threaded hole 35 can cooperate with the main sleeve 1 to achieve the purpose of limiting the placement frame 38.

[0021] Specifically, the surface of the pressing block 311 is provided with a protective device 4, which includes a built-in groove 46, which is formed on the surface of the pressing block 311.

[0022] In this embodiment, the built-in groove 46 can cooperate with the pressure block 311 to guide the push plate 41.

[0023] In this embodiment: a push plate 41 is placed on the surface of the built-in groove 46, and a slide rod 45 is fixedly connected to the lower surface of the push plate 41. The slide rod 45 is slidably connected to the surface of the pressure block 311, and the slide rod 45 can cooperate with the push plate 41 to guide the push plate 41.

[0024] Specifically, a pressure plate 43 is fixedly connected to the bottom end of the slide bar 45, and a protective pad 44 is fixedly connected to the surface of the pressure plate 43.

[0025] In this embodiment, the slide bar 45 can cooperate with the pressure plate 43 to push the pressure plate 43.

[0026] Specifically, a return spring 42 is fixedly connected between the push plate 41 and the built-in groove 46, and the return spring 42 is wound around the surface of the slide rod 45.

[0027] In this embodiment, the reset spring 42 can cooperate with the push plate 41 and the built-in groove 46 to achieve the purpose of resetting the pressure block 311.

[0028] Working principle: By setting the replacement device 3, rotating the limiting rod 36 disengages the limiting rod 36 from the threaded hole 35 and the placement frame 38, lifting the support frame 33 upwards. The support frame 33 then drives the placement frame 38 and the threaded rod 31, disengaging the support frame 33 from the placement groove 34. The worker then installs the new fixing component onto the placement groove 34. By setting the replacement device 3, the worker can effectively and conveniently replace the fixed component with damaged threads, avoiding the situation where the worker cannot stably clamp the square workpiece when fixing it, thereby improving the processing quality of the square workpiece. In addition, by setting the protection device 4, rotating the threaded rod 31, guided by the threaded ring 32, causes the threaded rod 31 to press against the pressure block 311. The pressure block 31 is then released by the reset spring. Spring 42 drives push plate 41, push plate 41 pushes slide rod 45, slide rod 45 pushes pressure plate 43, pressure plate 43 pushes protective pad 44. When protective pad 44 is placed on the workpiece, pressure plate 43 is resisted, and pressure block 311 will continue to slide. When pressure block 311 abuts against push plate 41, pressure block 311 will push push plate 41, push plate 41 pushes slide rod 45, slide rod 45 pushes pressure plate 43, and pressure plate 43 presses protective pad 44 to restrict the workpiece. When limit rod 36 retracts, pressure plate 43 is supported by the workpiece, and return spring 42 will pull pressure block 311 up, and pressure block 311 will move away from push plate 41. By setting protective device 4, the surface of the workpiece can be effectively protected, avoiding damage to the surface of the workpiece, thereby improving the quality of the workpiece.
