Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically a CNC roll lathe with rapid positioning. Background Technology

[0002] A roll lathe is a type of CNC lathe, which is a machine tool specifically used for processing rolls. During processing, one end of the roll is fixed to the machine tool's fixture, and then tightened by a center. The fixture then drives the roll to rotate, and the processing is achieved by using a cutting tool on the side.

[0003] Currently, the clamping seats of roll lathes on the market are mainly designed for positioning and fixing circular end faces. However, the clamping end of rolls often has a rectangular end face, which makes it impossible for traditional clamping seats to effectively position and clamp such rolls. Other types of clamping seats must be replaced to adapt to different end face shapes. This process is both complicated and time-consuming, reducing the flexibility and adaptability of operation, which may affect its overall practicality.

[0004] Therefore, this invention provides a CNC roll lathe with rapid positioning to solve the above problems. Summary of the Invention

[0005] This invention provides a CNC roll lathe with rapid positioning, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a CNC roll lathe for rapid positioning, the CNC roll lathe comprising a base plate, a lathe body fixedly mounted on the base plate, a fixture seat fixedly mounted on the top of the lathe body, a fixed frame fixedly mounted on one side of the fixture seat, and a clamping mechanism disposed inside the fixed frame for clamping the roll.

[0007] The clamping mechanism includes a fixed ring fixedly installed inside the fixed frame, a groove opened inside the fixed ring, a clamping block slidably installed inside the groove, a slider fixedly installed on the clamping block, a straight groove opened inside the fixed ring for the slider to slide, a rotating ring rotatably installed inside the fixed frame, an inclined groove opened inside the rotating ring for the slider to slide, a control frame fixedly installed on the fixed frame, a first threaded rod rotatably installed inside the control frame, a moving block screwed to the side surface of the first threaded rod, a rotating rod rotatably installed on the moving block, and connecting rods rotatably installed at both ends of the rotating rod.

[0008] Preferably, multiple sliding grooves are provided, and the sliding grooves are arranged in a ring array inside the fixed ring. Two rotating rings are provided, and the rotating rings are respectively arranged on both sides of the fixed ring.

[0009] Preferably, the movable block is slidably mounted inside the control frame, and the end of the connecting rod away from the rotating rod is rotatably connected to the side surface of the rotating ring.

[0010] Preferably, a guide rail is fixedly connected to the top of the lathe body, a movable plate is slidably connected to the top of the guide rail, and a placement rack is slidably connected to the top of the movable plate.

[0011] Preferably, connecting plates are fixedly connected to both sides of the movable plate, and fixing blocks are fixedly connected to both sides of the lathe body, with a second threaded rod rotatably connected between every two fixing blocks.

[0012] Preferably, the second threaded rod passes through the connecting plate, and the connecting plate has a threaded hole inside that is adapted to the second threaded rod.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Through the linkage design of the rotating ring, inclined groove and connecting rod in the clamping mechanism, when the rotating ring rotates, the inclined groove drives the slider to slide along the straight groove, which drives the clamping block to synchronously contract or expand along the radial direction of the groove, thereby achieving rapid clamping of the roll; at the same time, the groove and clamping block structure distributed in a ring array can adapt to rolls of different diameters, and can complete the clamping of rolls of multiple specifications without changing the fixture, significantly shortening the changeover adjustment time.

[0015] 2. The guide rail and moving plate on the top of the lathe body are equipped with a threaded rod structure. Under the control of the CNC system, the moving plate is driven to move linearly along the guide rail by rotating the threaded rod, which can achieve precise positioning of the axial position of the roll (the repeatability can reach ±0.05mm). The guiding effect of the guide rail ensures that the movement process is smooth and vibration-free, avoiding machining errors caused by the offset of the roll during the positioning process.

[0016] 3. The CNC system integrates bidirectional control of radial clamping and axial movement. Through program instructions, it synchronously coordinates clamping and positioning actions to achieve fully automated operation of the "clamping-movement-release" process, reducing manual intervention. At the same time, the system can be set with overload protection to avoid equipment damage caused by misoperation. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] This utility model provides a CNC roll lathe for rapid positioning, such as... Figures 1-5 As shown, it includes a base plate 1, a lathe body 2 fixedly mounted on the base plate 1, a fixture seat 3 fixedly mounted on the top of the lathe body 2, a fixing frame 4 fixedly mounted on one side of the fixture seat 3, and a clamping mechanism disposed inside the fixing frame 4 for clamping the rolls.

[0025] The clamping mechanism includes a fixed ring 5 fixedly installed inside the fixed frame 4, a slide groove 6 opened inside the fixed ring 5, a clamping block 7 slidably installed inside the slide groove 6, a slider 8 fixedly installed on the clamping block 7, a straight through groove 9 opened inside the fixed ring 5 for the slider 8 to slide, a rotating ring 10 rotatably installed inside the fixed frame 4, an inclined groove 11 opened inside the rotating ring 10 for the slider 8 to slide, a control frame 12 fixedly installed on the fixed frame 4, a first threaded rod 13 rotatably installed inside the control frame 12, a moving block 14 screwed to the side surface of the first threaded rod 13, a rotating rod 15 rotatably installed on the moving block 14, and a connecting rod 16 rotatably installed at both ends of the rotating rod 15.

[0026] Multiple slide grooves 6 are provided, and the slide grooves 6 are arranged in a ring array inside the fixed ring 5. Two rotating rings 10 are provided, and the rotating rings 10 are respectively arranged on both sides of the fixed ring 5.

[0027] The movable block 14 is slidably mounted inside the control frame 12, and the end of the connecting rod 16 away from the rotating rod 15 is rotatably connected to the side surface of the rotating ring 10.

[0028] When using this CNC roll lathe, the base plate 1 is first placed in a suitable position. Then, the roll to be processed is placed on the fixture seat 3 and clamped by the clamping mechanism. Specifically, by starting the external motor, the first threaded rod 13 is rotated, causing the moving block 14 screwed to the side surface of the first threaded rod 13 to slide inside the control frame 12. The sliding of the moving block 14 drives the rotating rod 15 and the connecting rod 16 rotatably mounted on both ends of the rotating rod 15 to move. The movement of the connecting rod 16 further drives the rotating ring 10 to rotate inside the fixed frame 4. Due to the rotation... The ring 10 has an inclined groove 11 for the slider 8 to slide inside, and the slider 8 is fixedly installed on the clamping block 7. The clamping block 7 is slidably installed inside the slide groove 6. Therefore, the rotation of the rotating ring 10 will cause the clamping block 7 to slide inside the slide groove 6. When the upper and lower clamping blocks 7 clamp the roller, when the moving block 14 moves again, the upper and lower clamping blocks 7 will no longer slide inward, but will instead cause the left and right clamping blocks 7 to slide inward, thus achieving the clamping of the circular or rectangular roller. After clamping is completed, the lathe body 2 is started to process the roller, which improves the processing efficiency and reduces the operation difficulty.

[0029] In order to facilitate the processing of rolls of different lengths, such as Figures 1-3 As shown, a guide rail 17 is fixedly connected to the top of the lathe body 2, a movable plate 18 is slidably connected to the top of the guide rail 17, and a placement rack 19 is slidably connected to the top of the movable plate 18.

[0030] When using this CNC roll lathe, the operator can place the roll to be processed on the placement frame 19. Since the placement frame 19 is slidably mounted on the top of the moving plate 18, and the moving plate 18 is slidably mounted on the top of the guide rail 17, the operator can adjust the position of the placement frame 19 on the moving plate 18 and the position of the moving plate 18 on the guide rail 17 to clamp and fix rolls of different lengths, thereby improving the applicability and practicality of the CNC roll lathe.

[0031] It should be noted that, in order to facilitate the sliding of the movable plate 18 on the guide rail 17, such as Figures 1-3 As shown, connecting plates 20 are fixedly connected to both sides of the movable plate 18, and fixing blocks 21 are fixedly connected to both sides of the lathe body 2. A second threaded rod 22 is rotatably connected between every two fixing blocks 21.

[0032] The second threaded rod 22 passes through the connecting plate 20, and the connecting plate 20 has a threaded hole inside that matches the second threaded rod 22.

[0033] When using this CNC roll lathe, the operator can start the external motor to drive the second threaded rod 22 to rotate synchronously. Since the second threaded rod 22 is compatible with the threaded hole inside the connecting plate 20, the second threaded rod 22 will push the connecting plate 20 to move during rotation. The connecting plate 20 drives the moving plate 18 to slide on the guide rail 17, thereby realizing the rapid adjustment of the position of the moving plate 18, further improving the efficiency of clamping and fixing rolls of different lengths, making the operation of the CNC roll lathe more convenient and reducing the labor intensity of the operator.

[0034] This invention achieves rapid, precise, and multi-specification positioning of rolls through innovative clamping mechanism design and CNC linkage control, significantly improving the processing efficiency and versatility of CNC roll lathes, and is suitable for high-precision processing scenarios of batch rolls.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
