Description

Technical Field

[0001] The utility model specifically relates to the technical field of positioning tooling, in particular to a CNC machining positioning tooling for a metal radiator. Background Art

[0002] The CNC machining center is an advanced mechanical processing equipment that plays a vital role in modern manufacturing. It can control the movement of the tool on multiple coordinate axes through pre-written programs, thereby realizing the processing of parts of various complex shapes. The advantages of the CNC machining center are numerous. First, its machining accuracy is high, which can reach the micron level, and can meet the production of parts with extremely high precision requirements. For example, in the aerospace field, the key components of aircraft engines need to rely on CNC machining centers to ensure accuracy and quality. Secondly, it has the characteristics of high efficiency. It can realize continuous and automated processing, greatly shortening the production cycle. For example, in automobile manufacturing, when mass-producing automobile parts, the high efficiency of the CNC machining center can significantly improve production efficiency and reduce costs. In addition, it also has good repeatability and stability. As long as the program does not change, the processed parts will have a high degree of consistency.

[0003] However, when CNC is machining a workpiece, it is necessary to clamp and fix the workpiece to avoid the workpiece from shifting during the machining process, resulting in incorrect machining positions, and even serious damage to the machining equipment. The traditional positioning tooling is in direct contact with the workpiece when clamping it. In this way, the workpiece may be affected by the squeezing force during the clamping process, causing the clamping position to deform, which cannot effectively guarantee the quality of the workpiece. In addition, the traditional positioning tooling can only achieve effective clamping and fixing of workpieces with neat edges. When clamping and fixing workpieces with special edges, it cannot effectively guarantee the stability of the workpiece clamping.

[0004] After searching, Chinese patent publication number CN202221564226.0 discloses a wire cutting positioning tool; it includes a plate positioning tool, a cutting plate is provided above the plate positioning tool, and the cutting plate is fitted and connected to the plate positioning tool, and a rubber button is provided on the outer side of the plate positioning tool, and the rubber button is rotatably connected to the plate positioning tool via an internal thread;

[0005] The positioning tooling plate in the above patent clamps the cutting plate by cooperating with the cylinder assembly and the rubber screw button to achieve the clamping and fixing of the cutting plate. Since the thrust of the cylinder assembly is large, the edge of the workpiece will be deformed when the push plate contacts the workpiece, which cannot effectively guarantee the quality of the workpiece. In addition, the above patent directly contacts the workpiece during clamping, which may affect the stroke of the machining tool during mechanical processing and cannot achieve the effect of one-time processing and forming.

[0006] In response to the above situation, we provide a CNC machining positioning tool for metal radiators. In this device, the radiator to be processed is pressed on the profiling plate by a pressing plate, and the bottom of the profiling plate is installed on a fixed plate. The clamping plate is driven by multiple cylinders to clamp the profiling plate, and the electric push cylinder drives the push rod to extend and retract to achieve the fit between the pressing plate and the radiator, thereby fixing the radiator on the profiling plate. In this way, during mechanical processing, the edge position of the radiator that needs to be processed will not be affected by the profiling plate and the pressing plate, and a groove is provided on the profiling plate to facilitate the snap-on engagement of the bottom of the radiator, which effectively ensures the stability of the installation between the radiator and the profiling plate, and ensures that there will be no offset during the processing.
