DETAILED DESCRIPTION
[0023] The following is a further detailed description of the implementation of the utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Combination Figure 1 , Figure 2 and Figure 3 As shown, a workpiece clamping device of a wire cutting machine tool includes a base 1, on which a symmetrically arranged adjusting device 3 is installed, the adjusting device 3 includes a cylinder 4 installed on the base 1, the output end of the cylinder 4 is fixedly connected to a movable plate 5, and a rotatable clamping mechanism 6 is installed on the movable plate 5. Specifically, the workpiece clamping device of the present invention includes a base 1, an adjusting device 3 and a clamping mechanism 6. A mounting hole 10 is provided on the base 1. The adjusting device 3 is symmetrically arranged on the base 1, and includes a cylinder 4, a movable plate 5 and a position sensor. The cylinder 4 is installed on the base 1, and the output end of the cylinder 4 is fixedly connected to the movable plate 5. A rotatable clamping mechanism 6 is installed on the movable plate 5. The clamping mechanism 6 includes a rotating shaft and a fixed plate, the rotating shaft is installed on the movable plate 5, and the fixed plate is fixed to the upper end of the rotating shaft. The position sensor is connected to the cylinder 4 for detecting the position of the movable plate 5. When in use, the position of the movable plate 5 is adjusted by adjusting the telescopic length of the cylinder 4 according to the size and shape of the workpiece to be clamped, thereby changing the clamping force and position of the clamping mechanism 6 on the workpiece. At the same time, according to the different shapes and positions of the workpiece, the angle of the fixed plate can be adjusted by the rotating shaft to improve the clamping effect. The position of the movable plate 5 can be detected in real time by the position sensor to achieve precise control of the movable plate 5. Through the cooperation of the adjustment device 3 and the clamping mechanism 6, the workpiece requiring different inclination angles can be cut by rotating the clamping mechanism 6, thereby increasing the application range of the clamping device and improving work efficiency.
[0025] Combination Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the clamping mechanism 6 includes a mounting plate 6a installed on one side of the movable plate 5. A rotary motor 6b is fixedly installed on the mounting plate 6a. The output end of the rotary motor 6b penetrates through the movable plate 5 and is fixedly connected to a rotary block 6c. An electric push rod 6d is arranged on the rotary block 6c. The output end of the electric push rod 6d penetrates through the top of the rotary block 6c and is fixedly connected to a clamping block 6e. Specifically, the design of the workpiece clamping device of this wire cutting machine tool has been further improved, especially the part of the clamping mechanism 6. The clamping mechanism 6 now includes a mounting plate 6a, which is fixed on one side of the movable plate 5. A rotary motor 6b is installed on the mounting plate 6a. The output end of the rotary motor 6b passes through the movable plate 5 and is fixedly connected to a rotary block 6c. The design of the rotary block 6c is quite ingenious. It can not only be driven to rotate by the rotary motor 6b, but also bear and transmit the force of the electric push rod 6d. An electric push rod 6d is arranged on the top of the rotary block 6c. The output end of the electric push rod 6d penetrates through the rotary block 6c and is fixedly connected to a clamping block 6e. This design further enhances the clamping force and clamping accuracy of the clamping mechanism 6. Through the cooperation of the rotary motor 6b and the rotary block 6c, the position and angle of the clamping block 6e can be accurately controlled, so as to realize more accurate workpiece clamping. At the same time, the use of the electric push rod 6d also increases the clamping force of the clamping block, ensuring the stability and safety of the workpiece during the processing.
[0026] Combined with Figure 2 、 Figure 4 and Figure 6 As shown, the rotary block 6c is of a U-shaped structure, and the clamping block 6e is installed inside the U-shaped structure. Specifically, the clamping mechanism 6 of the workpiece clamping device of this wire cutting machine tool has been further optimized. Among them, the rotary block 6c adopts a U-shaped structure. This design can better bear and fix the clamping block 6e, and at the same time provide greater clamping force and stability. The clamping block 6e is installed inside the U-shaped structure. Such a layout enables the clamping block 6e to clamp the workpiece more stably, and still be able to maintain the clamping of the workpiece when the rotary block 6c rotates. This design improves the stability and reliability of clamping, and avoids the sliding or loosening of the workpiece during the processing. In addition, this design also helps to reduce the overall size and weight of the device, making it more compact and lightweight. This may be particularly important for some small or light workpieces, because they require smaller clamping devices to ensure processing accuracy and stability.
[0027] Combined with Figure 1 、 Figure 2 、 Figure 4 and Figure 6As shown, a chute 6c1 is provided inside the C-shaped interior of the rotating block 6c, and a slider 6e1 is provided on one side of the clamping block 6e. The slider 6e1 and the chute 6c1 are slidably connected. Specifically, the clamping mechanism 6 of the workpiece clamping device of this wire cutting machine tool has been further improved and perfected. Among them, a chute 6c1 is provided inside the C-shaped interior of the rotating block 6c, and a slider 6e1 is provided on one side of the clamping block 6e. The slider 6e1 and the chute 6c1 are connected through sliding fit. This design not only improves the stability and reliability of the clamping mechanism 6, but also helps to reduce the size and weight of the clamping block. The design of the chute 6c1 enables the rotating block 6c to better carry and fix the clamping block 6e. At the same time, through the sliding fit connection between the slider 6e1 and the chute 6c1, the flexible movement of the clamping block 6e inside the rotating block 6c is realized. This design can better adapt to workpieces of different sizes and shapes and improve the adaptability of clamping. In addition, the sliding fit connection between the slider 6e1 and the chute 6c1 also makes the replacement and adjustment of the clamping block more convenient. Through a simple sliding operation, the clamping block 6e can be easily removed from or installed in the rotating block 6c, thus simplifying the maintenance and adjustment process.
[0028] Combined with Figure 1 , Figure 2 and Figure 3 As shown, movable grooves 1a are provided on both sides of the top of the base 1, and movable blocks 5a are provided on both sides of the bottom of the movable plate 5. The movable blocks 5a and the movable grooves 1a are slidably connected. Specifically, the design of the workpiece clamping device of this wire cutting machine tool has been further optimized. On both sides of the top of the base 1, movable grooves 1a are provided, and on both sides of the bottom of the movable plate 5, movable blocks 5a are provided. The movable blocks 5a and the movable grooves 1a are connected through sliding fit. This design enables the movable plate 5 to move horizontally on the base 1, thereby realizing the rapid and precise clamping of the workpiece. The design of this sliding fit connection not only simplifies the structure of the device, improves its flexibility and adaptability, but also makes the installation and adjustment of the device more convenient. The sliding fit connection between the movable blocks 5a and the movable grooves 1a enables the movable plate 5 to move freely along the horizontal direction of the base 1 to adapt to workpieces of different sizes and shapes. In addition, since the contact area between the movable blocks 5a and the movable grooves 1a is relatively large, the pressure per unit area can be reduced, preventing wear or damage caused by excessive pressure. At the same time, this design also helps to reduce the overall size and weight of the device, making it more compact and lightweight, and more convenient for transportation and use.
[0029] Combined with Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, the parts of the clamping block 6e and the rotating block 6c used for clamping are both installed with anti-skid pads. Specifically, this design takes into account the anti-skid requirements during the clamping process. By installing anti-skid pads on the clamping parts of the clamping block 6e and the rotating block 6c, the friction between the workpiece and the workpiece can be increased to prevent the workpiece from sliding during the clamping process, thereby improving the stability and reliability of the clamping. The choice of anti-skid pad material has a great influence on the anti-skid effect. It is necessary to select suitable materials according to actual use conditions to ensure that the workpiece can be effectively prevented from sliding under various circumstances. In addition, the installation position and fixing method of the anti-skid pad also need to be carefully considered to ensure that it will not shift or fall off during use. This design can further improve the working efficiency and processing quality of the wire cutting machine tool and reduce errors and problems caused by the sliding of the workpiece. In practical applications, it is necessary to appropriately adjust the material, installation position and fixing method of the anti-skid pad according to the specific situation to ensure that it can play the best anti-skid effect. At the same time, it is also necessary to pay attention to the maintenance and replacement of the anti-skid pad to ensure its service life and reliability.
[0030] Combination Figure 1 , Figure 2 and Figure 3 As shown, the bottom sides of the base 1 are provided with extensions 2, and the extensions 2 are provided with threaded holes 2a. Specifically, this design further enhances the stability and adjustability of the workpiece clamping device of the wire cutting machine tool. The extensions 2 provided on both sides of the bottom of the base 1 not only increase the rigidity and stability of the device, making it more durable, but also help to reduce the overall size and weight of the device, making it more compact and lightweight. More importantly, the threaded holes 2a provided on the extensions 2 provide greater flexibility for the installation and adjustment of the device. Through these threaded holes 2a, the device can be fixed to the machine tool base using fasteners such as bolts, thereby achieving quick and easy installation. In addition, these threaded holes 2a can also be used to connect other auxiliary components or devices to further expand the function and application range of the device. The design of this wire cutting machine tool workpiece clamping device improves the stability and adjustability of the device through optimization and innovation in multiple aspects, and also simplifies the installation and adjustment process. In practical applications, appropriate adjustments and maintenance are required according to the specific use environment and workpiece requirements to ensure that its performance reaches the best state.
[0031] Combination Figure 1 , Figure 2 and Figure 3As shown, the base 1, the adjusting device 3 and the clamping mechanism 6 are all made of metal. Specifically, this design selects metal as the material for the base 1, the adjusting device 3 and the clamping mechanism 6, mainly because metal has high strength, rigidity and wear resistance, which can ensure the stability and durability of the device during use. Metal materials can also withstand greater pressure and friction, are not easily deformed or damaged, and can ensure that the clamping mechanism maintains a stable clamping force during long-term use. In addition, the processing and manufacturing of metal materials are relatively easy, which can meet the design requirements of various complex structures, and can enhance its corrosion resistance and aesthetics through surface treatment.
