Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a fixture for complex parts with good adaptability. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in place, ensuring it maintains the correct relative position during machining. It is an indispensable and crucial piece of equipment in machining. In traditional machining, fixtures are used to fix the workpiece in order to ensure machining accuracy and improve production efficiency.

[0003] According to a part clamping structure disclosed in the above application (Announcement No.: CN223406461U), the upper outer wall of the clamping plate in the stabilizing mechanism is squeezed, which allows the clamping plate to rotate around the rotating rod. During the rotation of the clamping plate, the bottom of the part is lifted, which can prevent the part from falling during rotation. Furthermore, the setting of the adjusting rod can make the rotating roller rotate, so that the rotating roller can better fit with the bottom wall of the part for clamping. By the locking rod engaging inside the locking groove, the rotating roller on the outer wall of the adjusting rod driven by the rotating cylinder can be prevented from rotating after the rotating roller has stabilized the clamping of the part, which would lead to unstable clamping.

[0004] However, in actual use, although the above-mentioned equipment can limit the bottom of the part and prevent the roller from rotating after stabilizing the part, thus causing unstable clamping, it cannot be fully adapted to different parts. Therefore, we propose a fixture for complex parts with good adaptability. Utility Model Content

[0005] The purpose of this invention is to provide a fixture for complex parts with good adaptability, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixture for complex parts with good adaptability, including a base, an adaptability assembly for the fixture being provided on the outer wall of the base, the adaptability assembly including a protective shell, the protective shell being fixedly connected to the outer wall of the base, a motor being fixedly connected to the outer wall of the protective shell, a bidirectional lead screw being fixedly connected to the output end of the motor through the protective shell, and a slider being slidably connected to the outer wall of the bidirectional lead screw; A connecting movable plate is fixedly connected to the outer wall of the slider. A spring telescopic rod is rotatably mounted on the outer wall of the connecting movable plate. An installation plate is fixedly connected to the end of the spring telescopic rod. A movable insert rod is fixedly connected to the outer wall of the installation plate. A clamp is provided on the inner wall of the connecting movable plate. An installation screw groove is opened on the inner wall of the clamp. A threaded fixing bolt is detachably installed on the inner wall of the installation screw groove.

[0007] Preferably, the center line of the threaded fixing bolt is on the same straight line as the center line of the mounting screw groove and the center line of the collet.

[0008] Preferably, the number of sliders is two sets, and the two sets of sliders are arranged on both sides mirroring the center plane of the bidirectional lead screw.

[0009] Preferably, the slider is slidably connected to the inner wall of the protective shell, and the outer wall of the slider is adapted to the inner wall of the protective shell, so that the slider can move smoothly.

[0010] Preferably, the outer wall of the base is provided with a guide assembly for guiding the connecting movable plate. The guide assembly includes a vertical plate, which is fixedly connected to the outer wall of the base. A horizontal bar is fixedly connected to the outer wall of the vertical plate, and a sliding hole is provided on the outer wall of the connecting movable plate.

[0011] Preferably, the number of vertical plates is two sets, and the two sets of vertical plates are arranged on both sides of the center plane of the base.

[0012] Preferably, the crossbar is slidably connected to the inner wall of the sliding hole, and the outer wall of the crossbar is adapted to the inner wall of the sliding hole.

[0013] Compared with the prior art, this utility model provides a fixture for complex parts with good adaptability, which has the following beneficial effects: 1. This highly adaptable fixture for complex parts, when in daily use, starts the motor to drive the bidirectional lead screw to rotate, which in turn causes the limited slider to move the connecting moving plate and the chuck to shift. This allows the chuck to clamp the compatible part after shifting, facilitating subsequent processing. When the chuck needs to be replaced, the threaded fixing bolt can be easily removed and unscrewed for convenient replacement. After re-screwing the threaded fixing bolt, the elastic telescopic rod and mounting plate can be stretched, and the elastic telescopic rod can be rotated. After the moving insertion rod is aligned with the screwed-in threaded fixing bolt, the elastic telescopic rod can be released. This allows the elastic telescopic rod to retract and drive the moving insertion rod into the chuck, ensuring convenient replacement of the chuck and preventing the threaded fixing bolt from loosening.

[0014] 2. This highly adaptable fixture for complex parts, when the motor drives the bidirectional lead screw to rotate, thereby causing the limited slider to move the connecting moving plate and the chuck, the vertical plate and horizontal bar further provide stability to the connecting moving plate, allowing the connecting moving plate to slide smoothly on the outer wall of the horizontal bar through the sliding hole, ultimately improving the overall practicality and stability.

[0018] Furthermore, the connecting movable plate 205 is fixedly connected to the outer wall of the slider 204. A spring telescopic rod 206 is rotatably installed on the outer wall of the connecting movable plate 205. An installation plate 207 is fixedly connected to the end of the spring telescopic rod 206. A movable insert rod 208 is fixedly connected to the outer wall of the installation plate 207. A clamp 209 is provided on the inner wall of the connecting movable plate 205. An installation screw groove 210 is opened on the inner wall of the clamp 209. A threaded fixing bolt 211 is detachably installed on the inner wall of the installation screw groove 210.

[0019] In this embodiment of the utility model, the center line of the threaded fixing bolt 211, the center line of the mounting screw groove 210, and the center line of the chuck 209 are all on the same straight line. There are two sets of sliders 204, and the two sets of sliders 204 are mirror images of the center plane of the bidirectional lead screw 203 on both sides. The sliders 204 are slidably connected to the inner wall of the protective shell 201, and the outer wall of the sliders 204 is adapted to the inner wall of the protective shell 201, so that the sliders 204 can move smoothly.

[0020] Furthermore, the outer wall of the base 1 is provided with a guide assembly 3 for guiding the connecting movable plate 205. The guide assembly 3 includes a vertical plate 301, which is fixedly connected to the outer wall of the base 1. A horizontal bar 302 is fixedly connected to the outer wall of the vertical plate 301. A sliding hole 303 is opened on the outer wall of the connecting movable plate 205.

[0021] In this invention, during daily use, the starting motor 202 drives the bidirectional lead screw 203 to rotate, which in turn causes the limited slider 204 to move the connecting moving plate 205 and the chuck 209. This allows the chuck 209 to clamp the appropriate part after displacement, facilitating subsequent processing. When the chuck 209 needs to be replaced, the threaded fixing bolt 211 can be easily disassembled and unscrewed, making it easy to replace the chuck 209. After re-screwing the threaded fixing bolt 211, the elastic telescopic rod 206 and the mounting plate 207 can be stretched. The elastic telescopic rod 206 is then rotated so that the moving insertion rod 208 is aligned with the screwed-in threaded fixing bolt 211. The elastic telescopic rod 206 can then be released, allowing it to retract and drive the moving insertion rod 208 into the chuck 209. This ensures that the chuck 209 can be easily replaced and also prevents the threaded fixing bolt 211 from loosening.

[0022] When the motor 202 drives the bidirectional lead screw 203 to rotate, thereby causing the limited slider 204 to move the connecting moving plate 205 and the chuck 209, the vertical plate 301 and the horizontal bar 302 can further provide stability to the connecting moving plate 205, so that the connecting moving plate 205 can slide smoothly on the outer wall of the horizontal bar 302 through the sliding hole 303, ultimately improving the overall practicality and stability.
