[0002] The clamping device in a four-axis machine tool is a crucial component for fixing and positioning the workpiece. Its main function is to securely clamp the workpiece to be processed onto the machine tool's worktable, ensuring stability and accuracy during machining. Currently, in the use of four-axis machine tools, the clamping mechanism is typically set in a fixed manner. When machining plate-shaped workpieces on a four-axis machine tool, which are thin or thick, long or narrow, different clamping devices need to be installed according to the different shapes of the workpieces. This process is relatively cumbersome and inefficient, making it difficult to achieve the quick-change effect of the clamping mechanism on the four-axis machine tool. Furthermore, it is not applicable to plate-shaped workpieces of different shapes, which can affect the stability after clamping, thus reducing the effectiveness of the clamping device and indirectly affecting the machining efficiency of the four-axis machine tool.
[0003] Therefore, it is necessary to develop a quick-change clamping device for four-axis machine tools. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] This utility model provides the following technical solution: a quick-change clamping device for a four-axis machine tool. Please refer to [link / reference]. Figures 1-4 The system includes a four-axis machine tool 1. Guide grooves 101 are provided on both sides of the surface of the four-axis machine tool 1. A guide plate 102 is provided on the inner wall of one side of the guide groove 101. A base 2 is installed at the bottom of the four-axis machine tool 1. A mounting plate 201 is installed inside the lower part of the base 2. A motor 202 is installed at the bottom of the mounting plate 201. A rotating shaft 203 is installed at the output end of the motor 202. A movable seat 204 is threaded onto the outer wall of the rotating shaft 203. Movable plates 3 are installed on both sides of the top of the four-axis machine tool 1. A guide seat 301 is installed at the bottom of the movable plate 3. The outer wall of the guide seat 301 is slidably connected to the outer wall of the guide groove 101. The interior of the guide seat 301 is slidably connected to the outer wall of the guide plate 102. A support is rotatably connected to the bottom of the guide seat 301. The support arm A302 slides four sets of movable plates 3 onto the outer wall of the guide plate 102 on the four-axis machine tool 1 via the guide seat 301, allowing the four sets of movable plates 3 to move horizontally on the guide plate 102. At the same time, the guide plate 102 extends beyond the four-axis machine tool 1, thereby increasing the range of motion of the movable plates 3 and increasing the processing area of the four-axis machine tool 1. By installing the output end of the motor 202 in the base 2 with the rotating shaft 203, and rotatably connecting the top of the four sets of support arms A302 to the bottom of the guide seat 301, and rotatably connecting the bottom end to the movable seat 204 on the outer wall of the rotating shaft 203, the motor 202 drives the movable seat 204 to move up and down, simultaneously driving the four sets of movable plates 3 to move outward or inward.
[0023] A side frame 4 is mounted on the top of the movable plate 3. A rotating rod 401 is rotatably connected inside the side frame 4. A fixed seat 402 is mounted on one end of the rotating rod 401. A spring 403 is provided on one side of the outer wall of the rotating rod 401, and a knob 404 is threadedly connected to the other side of the outer wall of the rotating rod 401. Four sets of side frames 4 are installed on the top of the movable plate 3, and the fixed seat 402 is installed on one end of the rotating rod 401 inside the side frame 4. Rotating the rotating rod 401 will synchronously drive the fixed seat 402 to rotate. The knob 404 is threadedly connected to the rotating rod 4. On the outer wall of 01, a spring 403 is fitted on the outer wall. After the rotating rod 401 is rotated for adjustment, it is tightened by the knob 404 until the spring 403 deforms and contracts. Utilizing the elastic reaction force of the spring 403, the loosening of the knob 404 after tightening is minimized, preventing the rotating rod 401 from rotating again. A clamping plate 405 is installed on one side of the outer wall of the fixing base 402. Slides 406 are installed on the upper and lower sides of one side of the outer wall of the clamping plate 405. Slide grooves 40 are formed on the upper and lower surfaces of the clamping plate 405. 7. The outer wall of the slide block 406 is slidably connected to the interior of the slide groove 407. A support arm B408 is rotatably connected to the center of one side of the outer wall of the slide block 406. A tension spring 409 is provided between the opposite sides of the two sets of support arms B408. A limit post 410 is provided on one side of the outer wall of the slide block 406. The support arm B408 is rotatably connected between the slide block 406 on the clamping plate 405 and the fixed seat 402, and a tension spring 409 is provided between the two sets of support arms B408. Since the clamping plate 405 is cuboid in shape, it allows the rotating rod 40 to rotate. 1. To adjust the vertical or horizontal orientation of the clamping plate 405, place the plate workpiece on the table of the four-axis machine tool 1. The motor 202 drives and controls the four sets of side frames 4 to tighten inward until the clamping plate 405 clamps and fixes the plate workpiece. During this process, the clamping plate 405 can be adjusted according to the thinness, thickness, narrowness, or length of the plate workpiece to avoid situations where it is impossible to stably clamp the plate workpiece with different shapes. At the same time, adjusting the clamping plate 405 only requires rotating the rotating rod 401, which is simple to operate and achieves the effect of quick change.
[0024] Working principle: When using this utility model, four sets of movable plates 3 are slidably mounted on the outer wall of the guide plate 102 on the four-axis machine tool 1 via the guide seat 301, allowing the four sets of movable plates 3 to move horizontally on the guide plate 102. Simultaneously, the guide plate 102 extends beyond the four-axis machine tool 1, increasing the moving range of the movable plates 3 and thus increasing the processing area of the four-axis machine tool 1. A rotating shaft 203 is installed at the output end of the motor 202 inside the base 2, and the top ends of the four sets of support arms A302 are rotatably connected to the bottom of the guide seat 301, with the bottom ends rotatably connected... The movable seat 204, connected to the outer wall of the rotating shaft 203, moves up and down as driven by the motor 202, simultaneously moving the four sets of movable plates 3 outward or inward. By mounting the four sets of side frames 4 on the top of the movable plates 3 and installing the fixed seat 402 on one end of the rotating rod 401 within the side frames 4, rotating the rotating rod 401 synchronously drives the fixed seat 402 to rotate. A knob 404, threadedly connected to the outer wall of the rotating rod 401 and coupled with a spring 403 on the outer wall, allows the rotating rod 401 to be adjusted by the knob. Tighten knob 404 until spring 403 deforms and contracts. Utilizing the elastic reaction force of spring 403, this prevents loosening of knob 404 and avoids the possibility of the rotating rod 401 rotating again. Support arms B408 are rotatably connected between the slide 406 on the clamping plate 405 and the fixed seat 402, with a tension spring 409 placed between the two sets of support arms B408. Since the clamping plate 405 is cuboid in shape, rotating the rotating rod 401 adjusts the vertical or horizontal orientation of the clamping plate 405. This allows the plate-shaped workpiece to be placed on a four-axis machine tool. On the table, the motor 202 drives and controls the four sets of side frames 4 to tighten inward until the clamping plate 405 clamps and fixes the plate workpiece. During this process, the clamping plate 405 can be adjusted according to the thinness, thickness, narrowness or length of the plate workpiece to avoid situations where it is impossible to stably clamp the plate workpiece with different shapes. At the same time, adjusting the clamping plate 405 only requires rotating the rotating rod 401, which is simple to operate and achieves a quick change effect. This effectively improves the use of the clamping device on the four-axis machine tool and indirectly improves the processing effect of the four-axis machine tool.
