Abstract
Description
Technical Field
[0001] This utility model relates to the field of engraving machine technology, specifically to a tool magazine mechanism for an engraving machine. Background Technology
[0002] A multi-axis engraving machine is a high-precision, high-efficiency CNC machine tool. Based on digital control technology, it uses computer-generated graphics to export programs, which are then imported into the engraving machine to generate pulse signals that drive its multi-axis motion. The spindle rotates the cutting tool to perform precision machining on the workpiece. It has wide applications in fields such as machinery manufacturing, electronics, instrumentation, mold making, automobiles, and aerospace. In addition, multi-axis linkage engraving machines can also achieve mass production, further improving production efficiency and processing quality.
[0003] However, existing tool magazines for CNC engraving machines are simply installed on the side of the machine. When the machine needs to change tools, the machining head must stop working and move to the tool magazine to change the tool before it can continue processing. This leads to a decrease in the working efficiency of the CNC engraving machine. Furthermore, as the working position of the CNC engraving machine changes, the tool magazine cannot adapt to the position well. In addition, existing tool magazines are mostly fixed with bolts during installation, making it extremely inconvenient to disassemble and replace the tool magazine.
[0004] Therefore, we propose a tool magazine mechanism for a precision engraving machine. Utility Model Content
[0005] The purpose of this utility model is to provide a tool magazine mechanism for a precision engraving machine to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a tool magazine mechanism for a precision engraving machine, comprising:
[0007] A connecting plate, with connecting columns symmetrically fixedly connected to the bottom of the connecting plate, a connecting plate fixedly connected to the lower end of the connecting columns, multiple sets of adjustable tool holders arranged around the connecting plate, an adjustment mechanism for adjusting the position of the tool holders provided on the lower side of the connecting plate, and an installation mechanism for installing a tool magazine provided inside the connecting plate.
[0008] An adjustment mechanism, comprising an arc-shaped groove, a driven gear mounted on the bottom of the connecting plate, an arc-shaped groove being equidistantly arranged inside the driven gear, and a sliding rod being slidably mounted inside the arc-shaped groove;
[0009] The installation mechanism includes a locking post, which is installed inside the connecting plate. A recycling groove is symmetrically opened on the outside of the locking post, and a locking plate is rotatably installed inside the recycling groove.
[0010] Preferably, the adjustment mechanism further includes sliding grooves. Sliding grooves are sequentially and equidistantly arranged inside the connecting plate. A guide rail is fixedly connected to the outside of the connecting plate. An extension rod is slidably installed inside the guide rail, and the extension rod is fixedly connected to the sliding rod. Rotation of the driven gear drives the sliding rod to slide through the arc-shaped grooves. The movement of the sliding rod causes the extension rod to move within the guide rail. The forward movement of the extension rod within the guide rail simultaneously moves the tool holder, thereby changing the position of the tool holder. This allows the tool holder's position to be adjusted according to the position of the machining head, achieving adaptive adjustment.
[0011] Preferably, one end of the extension rod is fixedly connected to a tool holder, and each tool holder stores a tool for fine engraving, which facilitates quick tool replacement.
[0012] Preferably, a fixing plate is fixedly connected to the outer side of the connecting plate. A drive gear is rotatably mounted on the bottom of the fixing plate, and the outer side of the drive gear meshes with a driven gear. A rotary motor is mounted on the top of the fixing plate. A through hole is provided inside the fixing plate for connecting the output end of the rotary motor. The output end of the rotary motor passes through the inside of the fixing plate and is fixedly connected to the drive gear. When the rotary motor is started, the rotary motor drives the drive gear to rotate, and the rotation of the drive gear drives the outer meshing driven gear to rotate.
[0013] Preferably, the mounting mechanism further includes a clamping plate, a clamping plate fixedly connected to the outer side of the locking plate, a movable column installed inside the locking column, a spring installed on the outer side of the movable column with its bottom fixedly connected to the inside of the locking column, a chuck fixedly connected to the top of the movable column with its top fixedly connected to the chuck, and a pressing rod installed inside the locking column with its bottom contacting the top of the chuck. Pressing the pressing rod causes it to move inwards into the locking column under pressure. As the pressing rod moves, its bottom presses against the chuck, causing the chuck to move downwards, thus moving the clamping plate along with it. The movement of the clamping plate then moves the locking plate, which rotates and moves towards the center of the locking column until it is completely retracted into the recovery slot. At this point, the entire locking column is removed from the connecting plate, thus disassembling the tool holder.
[0014] Preferably, the locking post has a threaded groove on its outer side, and a rotating handle is installed on the outer side of the locking post. The rotating handle is engaged with the locking post through the threaded groove, and a handle is fixedly connected to the outer top of the locking post. By rotating the rotating handle, the rotating handle moves upward through the threaded groove, releasing the locking mechanism from the connecting plate.
[0015] Preferably, the outer side of the rotating handle is provided with an anti-slip groove.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the cooperation of the arc groove, sliding rod, connecting plate, sliding groove, guide rail, extension rod, tool holder, fixing plate, rotating motor, and drive gear, it can adaptively adjust according to the position change of the engraving machine head. The tool holder moves forward simultaneously with the tool changer, facilitating tool replacement, increasing replacement speed, and improving processing efficiency. Through the cooperation of the recovery groove, locking plate, clamping plate, moving column, spring, chuck, pressing rod, threaded groove, rotating handle, and handle, the tool holder can be quickly installed and disassembled, facilitating tool magazine replacement and maintenance. This avoids the traditional threaded connection method, improving the stability of the tool magazine body. Attached Figure Description

[0022] 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.
[0023] Please see Figure 1-4 A tool magazine mechanism for a CNC engraving machine, comprising:
[0024] A connecting plate 1 is provided, with connecting columns 2 symmetrically fixedly connected to the bottom of the connecting plate 1. A connecting plate 6 is fixedly connected to the lower end of the connecting column 2. Multiple sets of adjustable tool holders 10 are arranged around the connecting plate 6. An adjustment mechanism for adjusting the position of the tool holders 10 is provided on the lower side of the connecting plate 6. An installation mechanism for installing a tool magazine is provided inside the connecting plate 1.
[0025] The adjustment mechanism includes an arc groove 4. A driven gear 3 is installed at the bottom of the connecting plate 6. Arc grooves 4 are opened sequentially and equidistantly inside the driven gear 3. A sliding rod 5 is slidably installed inside the arc groove 4.
[0026] The installation mechanism includes a locking post 14, which is installed inside the connecting plate 1. A recycling groove 15 is symmetrically opened on the outside of the locking post 14, and a locking plate 16 is rotatably installed inside the recycling groove 15.
[0027] Please see Figure 1-4 The adjustment mechanism also includes sliding grooves 7. Sliding grooves 7 are equidistantly arranged inside the connecting plate 6. A guide rail 8 is fixedly connected to the outside of the connecting plate 6. An extension rod 9 is slidably installed inside the guide rail 8, and the extension rod 9 is fixedly connected to the sliding rod 5. When the driven gear 3 rotates, it drives the sliding rod 5 to slide through the arc-shaped groove 4. The movement of the sliding rod 5 causes the extension rod 9 to move within the guide rail 8. The forward movement of the extension rod 9 within the guide rail 8 simultaneously moves the tool holder 10, thereby changing the position of the tool holder 10. This allows the position of the tool holder 10 to be adjusted according to the position of the processing head, achieving adaptive adjustment.
[0028] Please see Figure 1-4 One end of the extension rod 9 is fixedly connected to a tool holder 10, and each tool holder 10 stores a tool for fine carving, which facilitates quick tool replacement.
[0029] Please see Figure 1-4 A fixing plate 11 is fixedly connected to the outer side of the connecting plate 6. A drive gear 13 is rotatably mounted on the bottom of the fixing plate 11, and the outer side of the drive gear 13 meshes with the driven gear 3. A rotary motor 12 is mounted on the top of the fixing plate 11. A through hole is provided inside the fixing plate 11 for connecting the output end of the rotary motor 12. The output end of the rotary motor 12 passes through the inside of the fixing plate 11 and is fixedly connected to the drive gear 13. When the rotary motor 12 is started, the rotary motor 12 drives the drive gear 13 to rotate, and the rotation of the drive gear 13 drives the outer meshing driven gear 3 to rotate.
[0030] Please see Figure 1-4The installation mechanism also includes a clamping plate 17, which is fixedly connected to the outer side of the locking plate 16. A moving column 18 is installed inside the locking column 14, and a spring 19 is installed on the outer side of the moving column 18. The bottom of the spring 19 is fixedly connected to the inside of the locking column 14. A chuck 20 is fixedly connected to the top of the moving column 18, and the top of the spring 19 is fixedly connected to the chuck 20. A pressing rod 21 is installed inside the locking column 14, and the bottom of the pressing rod 21 contacts the top of the chuck 20. When the pressing rod 21 is pressed, it is subjected to a pressing force and moves into the locking column 14. When the pressing rod 21 moves, its bottom presses against the chuck 20, causing the chuck 20 to move downwards, thereby moving the clamping plate 17 together. The movement of the clamping plate 17 causes the locking plate 16 to move, and the locking plate 16 rotates and moves towards the center of the locking column 14 until the locking plate 16 is completely retracted into the recovery slot 15. At this point, the locking column 14 is removed from the connecting plate 1, thereby disassembling the tool holder 10.
[0031] Please see Figure 1-4 The locking post 14 has a threaded groove 22 on its outer side, and a rotating handle 23 is installed on the outer side of the locking post 14. The rotating handle 23 is engaged with the locking post 14 through the threaded groove 22. A handle 24 is fixedly connected to the outer top of the locking post 14. By rotating the rotating handle 23, the rotating handle 23 moves upward through the threaded groove 22, releasing the locking mechanism from the connecting plate 1.
[0032] Please see Figure 1-4 The rotating handle 23 has an anti-slip groove 25 on its outer side.
[0033] Working Principle: When using this device, if the position needs to be changed according to the position of the machining head, the rotating motor 12 is started. The rotating motor 12 drives the driving gear 13 to rotate, which in turn drives the driven gear 3 meshing with it on the outside. The driven gear 3, through the engagement of the arc groove 4, drives the sliding rod 5 to slide. The movement of the sliding rod 5 drives the extension rod 9 to move within the guide rail 8. The extension rod 9 moves forward within the guide rail 8, simultaneously moving the tool holder 10, thereby changing the position of the tool holder 10. This adaptive adjustment changes the position of the tool holder 10 according to the position of the machining head. When the entire tool holder 10 needs to be replaced, the rotating handle 23 is rotated. The rotation of the rotating handle 23 passes through the threaded groove 22. The locking pin 10 is disassembled by pressing the compression rod 21, which moves upward to release the contact lock between the locking pin 1 and the connecting plate 1. The compression rod 21 is then pressed and moves into the locking pin 14 under the pressure. When the compression rod 21 moves, its bottom presses against the chuck 20, which moves downward under the pressure. This causes the chuck 20 to move along with the locking plate 17. The movement of the locking plate 17 causes the locking plate 16 to move. The locking plate 16 rotates and moves toward the center of the locking pin 14 until it is completely retracted into the recovery slot 15. At this point, the locking pin 14 is removed from the connecting plate 1, thus disassembling the tool holder 10. To reinstall, the locking pin 14 is directly inserted into the connecting plate 1. The locking plate 16 unfolds outward under the pressure of the spring 19 and then engages with the rotating handle 23 to achieve connection and locking.
