Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and more specifically, to a transverse tool changing mechanism. Background Technology

[0002] A tool magazine system is a device that provides the tool storage and tool changing capabilities required in automated machining processes. Its automatic tool changing mechanism and tool magazine that can store multiple tools have changed the traditional human-based production method. Through computer program control, it can complete various machining requirements, such as milling, drilling, boring, and tapping, which significantly shortens the machining time and reduces production costs.

[0003] In the existing technology, the traditional disc tool magazine tool changing operation requires several rotating mechanisms to assist the tool body in rotating and then cooperating with the tool changing mechanism to perform the tool changing operation. This results in the disc tool magazine having multiple tool magazines and rotating mechanisms, thereby increasing the design cost of the disc tool magazine and adding rotating operation steps.

[0004] A search revealed that Chinese patent CN220312615U discloses a disc tool magazine tool changing mechanism. The rotation of the disc tool magazine causes the internal machining tool to rotate as well. The operation of the cylinder causes the first clamping plate to slide towards the machining tool, so that the first clamping plate and the second clamping plate clamp and limit the machining tool. The telescopic device causes the tool changing plate to slide downward, thereby disengaging the machining tool from the tool slot. The rotating device rotates the tool changing plate to perform the tool changing operation. This tool changing method does not require a rotating mechanism on the disc tool magazine, saving design costs and eliminating the need for a rotation operation step on the machining tool.

[0005] In actual use, the existing disc tool magazine tool changing mechanism uses a snap ring to hold the tool at a specific part. However, the clamping force of the snap ring will weaken due to long-term use or wear, which may cause the tool to shake or loosen during the tool changing process. At the same time, it needs to be inspected and replaced regularly, which increases the maintenance cost and time of the equipment. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] The embodiments disclosed in this application are as follows: Figure 1-7 The transverse tool changing mechanism shown includes a support frame 1, a disc tool magazine 2 fixedly connected to one side of the support frame 1, a machining tool body 3 provided on one side of the disc tool magazine 2, a fixed bracket 4 fixedly connected to one side of the support frame 1, a transverse mechanism installed on the outside of the fixed bracket 4, a movable housing 5 installed above the fixed bracket 4, a tool changing plate 6 provided on one side of the movable housing 5, and a clamping assembly installed inside the tool changing plate 6.

[0026] The clamping assembly includes an electric push rod 8, which is fixedly connected to one side of the tool changer plate 6. A groove 7 is provided on one side of the tool changer plate 6. A sliding plate 9 is fixedly connected to the output end of the electric push rod 8, and the sliding plate 9 slides within the groove 7. A connecting bracket 10 is fixedly connected to one end of the sliding plate 9. Two positioning blocks 11 are fixedly connected to the inner side of the connecting bracket 10, and two sliding rods 12 are fixedly connected to the outer side of the positioning blocks 11. A first movable rod 13 and a second movable rod 14 are provided on the outer side of the positioning blocks 11. A support shaft 15 is rotatably connected inside the first movable rod 13 and the second movable rod 14, and the support shaft 15 is fixedly connected to the inside of the tool changer plate 6. Two guide grooves 16 are provided on the outer side of both the first movable rod 13 and the second movable rod 14, and the inner side of the guide grooves 16 slides with the sliding rod 12. A clamping ring 18 is fixedly connected to one end of both the first movable rod 13 and the second movable rod 14. The first movable rod 13 and the second movable rod 14 are located inside the tool changer plate 6. The movable connection utilizes an electric push rod 8 to drive a sliding plate 9 to slide inside a slide groove 7. The sliding plate 9 can move two positioning blocks 11 via a connecting bracket 10. It slides inside a guide groove 16 via a sliding rod 12 and is hinged to the first movable rod 13 and the second movable rod 14 via a support shaft 15. This allows the positioning blocks 11 to slide inside the guide groove 16 on one side of the first movable rod 13 and the second movable rod 14 via a sliding rod 12 on one side. This pushes the first movable rod 13 and the second movable rod 14 to move relative to each other, causing the clamping ring 18 to clamp the machining tool body 3. By using the other sliding rod 12 to slide inside the guide groove 16 on the other side of the first movable rod 13 and the second movable rod 14, the first movable rod 13 and the second movable rod 14 can be pulled to open the clamping ring 18 outward. This provides a more stable clamping force and reduces the risk of the machining tool body 3 accidentally moving or loosening during clamping.

[0027] Reference Figure 3 and 4As shown, the traversing mechanism includes a servo motor 19, which is fixedly connected to the inside of the moving housing 5. A rotating shaft 20 is fixedly connected to the output end of the servo motor 19. A turntable 21 is fixedly connected to the outside of the rotating shaft 20. A hydraulic rod 22 is fixedly connected to one side of the turntable 21. The outside of the hydraulic rod 22 is fixedly connected to the tool changer 6. A stepper motor 23 is fixedly connected to one side of the fixed bracket 4. Two guide rods 27 are fixedly connected to the upper surface of the fixed bracket 4. A lead screw 24 is fixedly connected to the output end of the stepper motor 23. The lead screw 24 is rotatably connected to the inside of the fixed bracket 4. A threaded bracket 25 is threadedly connected to the outside of the lead screw 24. Multiple sliding blocks 26 are fixedly connected to the bottom end of the threaded bracket 25. The sliding blocks 26 are slidably connected to the outside of the guide rods 27. Next, the extension and retraction of the hydraulic rod 22 can drive the machining tool body 3 to separate from the disc tool magazine 2 via the tool changer 6. The machining tool body 3 can also be inserted into the spindle connection port of the support frame 1 via the tool changer 6. The lead screw 24 provides the power source for the movement of the movable housing 5. It is slidably connected to the outer side of the guide rod 27 via the sliding block 26, so that the movable housing 5 can stably drive the machining tool body 3 to move, so that the machining tool body 3 can maintain good stability during the tool change process. The servo motor 19 provides the power source for the rotation of the tool changer 6, so that the tool changer 6 can drive the machining tool body 3 to rotate the clamping ring 180°. Through the lateral movement, the required machining tool body 3 can be quickly transported from the support frame 1 to the spindle position.

[0028] Working principle of this utility model: This utility model designs a transverse tool changing mechanism, the specific structure of which is shown in the attached instruction manual. Figure 1-7As shown, in this technical solution, through the cooperation between various structures, when a tool change is required, the stepper motor 23 is first started. The stepper motor 23 drives the lead screw 24 to rotate. The lead screw 24 drives the moving housing 5 to move towards the side of the disc tool magazine machine 2 via the thread. Then, the electric push rod 8 is started, which pulls the sliding plate 9 to slide inside the slide groove 7. The movement of the sliding plate 9 can drive the connecting bracket 10 to move. The connecting bracket 10 can drive the sliding rod 12 on one side to move into the guide groove 16 on the side of the first movable rod 13 and the second movable rod 14 through the positioning block 11. Lateral sliding is achieved by hinged pivot 15 to the inner sides of the first movable rod 13 and the second movable rod 14, allowing both the first and second movable rods 13 and 14 to open the clamping rings 18 outwards. Through continuous movement of the moving housing 5, the two clamping rings 18 can move onto the outer retaining ring of the machining tool body 3. Then, the electric push rod 8 pushes the sliding plate 9, causing the connecting bracket 10 to separate the two positioning blocks 11 from the guide grooves 16 on the other side of the first and second movable rods 13 and 14. Simultaneously, the positioning blocks 11 can be connected to the first and second movable rods 13 and 14 via the sliding rod 12 on one side. The guide groove 16 on one side of the movable rod 14 separates, so that the two positioning blocks 11 can push the first movable rod 13 and the second movable rod 14 to drive the clamping ring 18 to move relative to each other, so that the two clamping rings 18 can clamp the machining tool body 3. Then, the hydraulic rod 22 is activated, and the hydraulic rod 22 can drive the tool changing plate 6 to extend to the support frame 1, so that the machining tool body 3 is separated from the disc tool magazine 2. Then, the servo motor 19 is activated, and the servo motor 19 drives the rotating shaft 20 to rotate. The rotating shaft 20 can drive the turntable 21 to rotate, so that the turntable 21 can drive the extended hydraulic... The lever 22 rotates the clamping ring 180°, which facilitates the tool changer 6 to drive the machining tool 3 to rotate the clamping ring 180°. The stepper motor 23 is started, which drives the lead screw 24 to rotate in the opposite direction, so that the lead screw 24 can drive the movable housing 5 to move towards the support frame 1. The sliding block 26 is slidably connected to the outside of the guide rod 27, which facilitates the movable housing 5 to stably drive the tool changer 6 to move towards the support frame 1. Finally, the hydraulic lever 22 is retracted, so that the tool changer 6 can drive the machining tool 3 to be inserted into the spindle connection port on the side of the support frame 1, thereby completing the replacement of the machining tool 3.
