[0030] This utility model proposes a jig clamping device 100.

[0031] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the jig clamping device 100 includes a frame 1, a connecting assembly, a clamping assembly, and a positioning block 6; the connecting assembly is movably disposed on the frame 1; the clamping assembly includes a mounting plate 2, a first clamping mechanism, and a second clamping mechanism, the mounting plate 2 is connected to the connecting assembly, the first clamping mechanism and the second clamping mechanism are disposed at opposite ends of the mounting plate 2, and the second clamping mechanism is movably connected to the mounting plate 2 to move closer to or further away from the first clamping mechanism; the positioning block 6 is disposed at the end of the first clamping mechanism away from the mounting plate 2.

[0032] In the technical solution of this utility model, a positioning block 6 is provided at the end of the first clamping mechanism away from the mounting plate 2. The positioning block 6 can abut against the workpiece to accurately position it, ensuring correct clamping of the workpiece and thus improving processing quality. In addition, the second clamping mechanism is movably connected to the mounting plate 2, and the distance between it and the first clamping mechanism can be flexibly adjusted to adapt to workpieces of different sizes and shapes.

[0033] Specifically, in one embodiment of this utility model, please refer to... Figure 1 The first clamping mechanism includes a first connecting plate 4 and two clamping arms 3 located on opposite sides of the first connecting plate 4. The first connecting plate 4 is fixedly connected to the mounting plate 2. The second clamping mechanism includes a second connecting plate 5 and two clamping arms 3 located on opposite sides of the second connecting plate 5. The second connecting plate 5 is movably connected to the mounting plate 2. The arrangement of the four clamping arms 3 can evenly distribute the clamping force, avoiding excessive local pressure that could lead to workpiece deformation or damage, and further improving the reliability of clamping and the integrity of the workpiece.

[0034] Furthermore, in one embodiment of this utility model, please refer to... Figure 1 and Figure 2 Each clamping arm 3 has a positioning block 6 at the end furthest from the mounting plate 2. The positioning block 6 at the end of each clamping arm 3 furthest from the mounting plate 2 provides multiple precise positioning reference points for the workpiece. During clamping, these positioning blocks 6 can limit and correct the workpiece from different positions, effectively reducing positional deviations and significantly improving processing quality.

[0035] For versatility, in one embodiment of this invention, the positioning block 6 is detachably connected to the clamping arm 3. This detachable connection allows the positioning block 6 to be easily replaced or adjusted, thus adapting to workpieces of various sizes and shapes, meeting the needs of different production tasks, and expanding the applicability of the equipment. Furthermore, the detachable connection design between the positioning block 6 and the clamping arm 3 allows for quick disassembly and installation when maintenance or replacement of the positioning block 6 is required. This not only reduces the time and difficulty of equipment maintenance but also improves the maintainability of the equipment and lowers maintenance costs.

[0036] Specifically, in one embodiment of this utility model, please refer to... Figure 1 The mounting plate 2 is equipped with a linear slide rail; the second clamping mechanism also includes a first drive module 7 and a first slider. The first slider is slidably mounted on the linear slide rail and connected to the second connecting plate 5. The first drive module 7 is mounted on the mounting plate 2 and drives the first slider to slide. The linear slide rail and the first slider make the movement of the second clamping mechanism smoother and more precise. The first drive module 7 can accurately control the position of the second clamping mechanism, ensuring that its relative position with the first clamping mechanism reaches the expected value, thereby improving the clamping accuracy. The first drive module 7 can be a cylinder or an electric push rod that directly drives the first slider to slide along the linear slide rail, or it can be a stepper motor or servo motor that drives the first slider to slide along the linear slide rail via a screw or belt drive.

[0037] Furthermore, in one embodiment of this utility model, please refer to... Figure 1 and Figure 2The clamping assembly also includes four joint clamping mechanisms, each located on a clamping arm 3. These four joint clamping mechanisms work together to clamp the workpiece. Each joint clamping mechanism includes a needle-type cylinder 8, a connecting block 9, and a clamping block 10. The needle-type cylinder 8 is located on the clamping arm 3 and is inclined relative to it. One end of the connecting block 9 is connected to the piston rod of the needle-type cylinder, and the other end is rotatably connected to the clamping block 10. The clamping block 10 is rotatably located at the lower end of the clamping arm 3. The four clamping blocks 10 work together to clamp the workpiece. The four joint clamping mechanisms are located on each clamping arm 3. Through the precise control of the needle-type cylinder 8, the workpiece can be clamped from multiple directions. This multi-point clamping method ensures accurate positioning of the workpiece in all directions, effectively reducing positional deviations during clamping and thus improving processing quality. The rotatable connection design between the clamping block 10 and the connecting block 9 allows the clamping block 10 to automatically adjust its angle according to the shape and position of the workpiece, better conforming to the workpiece surface. This adaptive adjustment capability prevents clamping instability caused by irregular workpiece shape or uneven surface, ensuring the stability of the machining process.

[0038] Furthermore, in one embodiment of this utility model, please refer to... Figure 1 The connecting assembly includes a horizontal moving mechanism and a vertical moving mechanism. The horizontal moving mechanism is slidably mounted on the frame 1, and the vertical moving mechanism connects the output end of the horizontal moving mechanism to the mounting plate 2. The horizontal moving mechanism drives the vertical moving mechanism to move horizontally, and the vertical moving mechanism drives the mounting plate 2 to move vertically. The coordinated operation of the horizontal and vertical moving mechanisms allows the clamping assembly to adapt to different processing positions. This flexibility enables the device to cope with various complex production environments and different processing requirements. Through automated control, the horizontal and vertical moving mechanisms can quickly and accurately move the clamping assembly to the designated position, reducing the time and error of manual adjustments, thereby improving overall production efficiency.

[0039] Specifically, in one embodiment of this utility model, please refer to... Figure 1 The lateral moving mechanism includes a second drive module 11, a lateral slide rail, and a second slider. The second drive module 11 and the lateral slide rail are mounted on the frame 1. The second slider is slidably mounted on the lateral slide rail. The second drive module 11 drives the second slider to slide, and the second slider is connected to the vertical moving mechanism. The arrangement of the lateral slide rail and the second slider makes the horizontal movement of the vertical moving mechanism smoother and more precise. The second drive module 11 can accurately control the position of the second slider, thereby ensuring the accuracy of the vertical moving mechanism during lateral movement. The second drive module 11 can be a cylinder or an electric push rod that directly drives the second slider to slide, or it can be a stepper motor or servo motor that drives the second slider to slide via a screw or belt drive.

[0040] Furthermore, in one embodiment of this utility model, please refer to... Figure 1 The vertical movement mechanism includes a drive cylinder 12 and multiple telescopic rods 13. The drive cylinder 12 is located at the output end of the horizontal movement mechanism, and its piston rod is connected to the mounting plate 2.
