Description

Technical Field

[0001] The utility model relates to a fixing device, in particular to a machine tool mould fixing device, belonging to the technical field of machine tool processing. Background Art

[0002] Machine tools and molds are two crucial areas in modern manufacturing. Machine tools, as industrial mother machines, are the core equipment for manufacturing various mechanical parts and products. They use precise mechanical movements to achieve material cutting, forming, grinding and other processing processes, while molds are tools used to form and shape materials in the manufacturing process to obtain specific shapes and sizes. The accuracy and performance of machine tools directly affect the manufacturing quality of molds, and high-quality molds can improve product quality and production efficiency. Molds are usually used to produce large batches of products, such as plastics and metal parts. The fixation of machine tool molds is an important link in mechanical processing, especially in mold processing, stamping, forming, die-casting and other processes. Accurate fixation of molds is crucial to ensure the dimensional accuracy, shape and surface quality of workpieces;

[0003] A Chinese public patent (publication number: CN218224336U) discloses a stamping die fixing tool, including a middle plate, a left plate and a right plate. The stamping die fixing tool can adjust the distance between the left plate and the right plate and the middle plate respectively through an auxiliary adjustment unit, so that the stamping die fixing work can be adapted to different stamping dies. The stamping die placed on the surface of the fixed table can be matched and fixedly clamped through the fixing unit, so that the fixing work of the stamping die by the stamping die fixing tool can be quickly completed. The telescopic rod can be assisted to be extended and retracted through the buffer spring, and the rotation adjustment of the adjustment rod can be more convenient through the rotary handle. The outer surface of the stamping die can be buffered and protected by the buffer pad when the splint and the stamping die are matched and fixed, the left plate and the right plate can be fixedly supported by the support plate, and the supporting effect of the support plate on the left plate and the right plate can be improved through the fixing hole.

[0004] The fixing tool fixes the mold by rotating the adjusting rod in sequence to drive the clamping plate to move, but the method is relatively cumbersome and it is impossible to ensure that the moving positions of the two clamping plates are the same. If the clamping is unstable, it is easy to affect the quality of the produced product. Therefore, a machine tool mold fixing device is proposed. Utility Model Content

[0025] In one embodiment, a first bearing 7 is fixedly mounted on the outer side of the circular column 5 , and the outer side of the first bearing 7 is fixedly connected to the inner wall of the sleeve 6 . The sleeve 6 is rotatably mounted on the outer side of the circular column 5 through the provision of the first bearing 7 .

[0026] In one embodiment, an internal threaded barrel 302 is rotatably installed on the right side of the inner wall of the rectangular box 2, and the right end of the internal threaded barrel 302 extends to the right side of the rectangular box 2. The internal thread of the internal threaded barrel 302 is connected to a threaded rod 306, and the left end of the threaded rod 306 is rotatably installed with a rectangular plate 305. The rectangular plate 305 is slidably set on the upper surface of the base 1, and the two limiting plates 4 are rotatably installed on the side close to each other, and the other end of the connecting rod 304 is rotatably connected to the left side of the rectangular plate 305. By rotating the internal threaded barrel 302, the threaded rod 306 that is threadedly matched with the internal threaded barrel 302 moves, and at the same time, the moving threaded rod 306 drives the rectangular plate 305 to move, and the rectangular plate 305 moves and pushes the two connecting rods 304 to rotate, and the two rotating connecting rods 304 drive the two limiting plates 4 to rotate, and the mold is clamped and fixed by the two limiting plates 4.

[0027] In one embodiment, a through hole 8 is opened on the right side of the rectangular box 2, and a second bearing 9 is fixedly installed inside the through hole 8. The inner wall of the second bearing 9 is fixedly connected to the outer side of the internal threaded tube 302. Through the setting of the second bearing 9, the internal threaded tube 302 is rotatably installed on the right side of the inner wall of the rectangular box 2.

[0028] In one embodiment, a guide groove 303 is provided on the upper surface of the base 1, and a guide block 307 is fixedly installed on the lower surface of the rectangular plate 305. The outer side of the guide block 307 is in movable contact with the inner wall of the guide groove 303. The movement of the rectangular plate 305 is guided by the cooperation between the set guide block 307 and the guide groove 303.

[0029] In one embodiment, a rotating handle 301 is fixedly mounted on the right end of the internally threaded barrel 302 , and the rotating handle 301 assists in rotating the internally threaded barrel 302 , thereby improving portability during use.

[0030] In one embodiment, mounting plates 10 are fixedly installed on the left and right sides of the base 1, and mounting nuts are movably provided inside the mounting plates 10. When the entire device needs to be installed, the base 1 is installed on the upper surface of the machine tool through the mounting plates 10 and the mounting nuts.

[0031] When the utility model is working: when the whole device needs to be installed on the upper surface of the machine tool, the base 1 is placed on the upper surface of the machine tool, and the lower surface of the mounting plate 10 is in contact with the upper surface of the machine tool. The mounting plate 10 is fixed by the mounting nut inside the mounting plate 10, and the base 1 is fixed to the upper surface of the machine tool. When the mold needs to be fixed, the handle 301 is rotated clockwise to make the handle 301 drive the internal threaded barrel 302 to rotate. Since the internal threaded barrel 302 is threadedly matched with the threaded rod 306, the internal threaded barrel 302 rotates At the same time, the threaded rod 306 moves to the left, and the moving threaded rod 306 drives the rectangular plate 305 to move to the left. The rectangular plate 305 drives the guide block 307 to move inside the guide groove 303 while moving. The rectangular plate 305 drives the two connecting rods 304 to rotate away from each other. The two connecting rods 304 drive the two limiting plates 4 to rotate away from each other. The limiting plates 4 drive the first bearing 7 to rotate outside the circular column 5. At this time, the distance between the two limiting plates 4 can be expanded, and then the mold is placed on the upper surface of the base 1.

[0032] The handle 301 is rotated counterclockwise, and the handle 301 drives the internal threaded cylinder 302 to rotate. The internal threaded cylinder 302 rotates in the opposite direction, and the threaded rod 306 moves rightward. The moving threaded rod 306 drives the rectangular plate 305 to move rightward. The rectangular plate 305 moves rightward, and the two connecting rods 304 rotate in the opposite direction toward each other. The connecting rod 304 drives the two limiting plates 4 to rotate in the opposite direction toward each other. The limiting plate 4 drives the first bearing 7 to rotate on the outside of the circular column 5 until the two limiting plates 4 are aligned with the front and rear sides of the mold. The sides of the mold are in contact, and the handle 301 is stopped at this time. Under the self-locking of the threads of the internal threaded tube 302 and the threaded rod 306, the position of the rectangular plate 305 is fixed, and the two connecting rods 304 and the two limit plates 4 are fixed at the same time. The mold is clamped and fixed by rotating the two limit plates 4 inward at the same time, so that the two limit plates 4 can be rotated inward at the same time by rotating an internal threaded tube 302, thereby clamping and fixing the mold through the two limit plates 4, thereby improving the portability during use.
