Description

Technical Field

[0001] The utility model relates to the technical field of sample clamping, in particular to a clamping device for fixing irregular samples used in a wire cutting machine. Background Art

[0002] Wire cutting machine is one of the important processing equipment in modern manufacturing industry, which is widely used in precision cutting of various materials such as metal, plastic, ceramic, etc. Wire cutting technology is favored for its high precision and high flexibility, especially when processing complex shapes or irregular samples. However, for the processing of irregular samples, the traditional clamping device of wire cutting machine is often difficult to adapt to the changing shapes and sizes. Incorrect selection of the clamping device of wire cutting machine and loose clamping may lead to the scrapping of workpieces. It is very important to choose the right clamping device.

[0003] With the development of industrial automation and precision manufacturing, the requirements for wire cutting machine clamping devices are getting higher and higher. The wire cutting clamps currently used in the market are generally the pressure plate clamps that come with the machine tool. They have a simple structure and are only suitable for clamping relatively regular specimens. Although some specially designed clamping devices can adapt to irregular specimens, they are often complex in structure, expensive, and the adjustment process is cumbersome, which is not conducive to rapid production change and efficient production.

[0004] In recent years, in order to solve the above problems, some new clamping device design schemes have emerged in the industry. These schemes attempt to improve the adaptability to irregular specimens by improving the design of the clamping mechanism. For example, the use of adjustable clamping arms, flexible clamping materials, or automatic adjustment systems based on machine vision and other technical means. The development of these technologies has improved the processing capabilities of wire cutting machines for irregular specimens to a certain extent, but there are still problems such as limited adaptability, complex operation, or high cost, which cannot fully meet the needs of modern precision manufacturing. Therefore, the development of a new type of wire cutting machine clamping device suitable for irregular specimens, which can not only ensure processing accuracy and efficiency, but also reduce costs and operating difficulties, has become a problem that needs to be solved urgently in the current field of wire cutting technology.

[0005] The Chinese patent application with publication number CN206561284U was submitted by Tu Yingming et al., and relates to a clamping device for a metallographic sample cutting machine. The device includes a pad, a base, a left fixed clamping end, a right fixed clamping end, a left movable clamping end, a right movable clamping end, a locking device, and a jacking device, wherein each clamping end has neatly arranged elastic units, and each unit can independently perform reciprocating linear motion under the action of its own contact spring. This design changes the surface clamping or line clamping of the traditional cutting machine clamping device into point clamping, realizing multi-point contact to adapt to the maximum fitting of irregular sample surfaces, solve the problem of difficult or loose clamping of irregularly shaped samples, or even the sample flying out at the moment of cutting, and eliminate potential safety hazards. However, it still has the following technical problems: although effective clamping of irregular samples is achieved, the complexity of the device may lead to increased maintenance costs and increased difficulty in operation, and under extreme working conditions, the reliability of multi-point contact may be affected, resulting in unstable clamping effect.

[0006] The Chinese patent document with publication number CN215091184U discloses a clamping device for a CNC wire cutting machine tool, which includes a machine tool, a combination clamping plate is arranged on both sides of the top of the machine tool, a movable clamping block is arranged in the combination clamping plate, and a smart lock is arranged on the two side walls outside the movable clamping block, and the smart lock is composed of a permanent magnet, a limit spring, an electromagnet, a sleeve and a power supply system. Although the device has a sample clamping function, the device is applicable to limited samples, and in the actual cutting process, the CNC system cannot accurately identify the shape and size of the sample, and it is difficult for the pressure plate clamp to fix irregular samples.

[0007] Therefore, the utility model provides a clamping device for fixing irregular samples for a wire cutting machine, which can fix and clamp irregular samples, and has important practical application value for improving cutting accuracy and cutting efficiency and ensuring cutting quality.
