Technical Field

[0001] This utility model relates to the field of CNC cutting tool technology, specifically a tool holder for CNC machine tools. Background Technology

[0002] CNC cutting tools are tools used for cutting processes in mechanical manufacturing, also known as cutting tools. In a broad sense, cutting tools include both cutting tools and grinding wheels; in addition to cutting inserts, CNC cutting tools also include accessories such as tool holders and tool shanks.

[0003] In the prior art, Chinese utility model publication number CN217832915U discloses a tool holder for CNC machine tools, including a base and a horizontal placement plate. Supporting side plates are symmetrically arranged on both sides of the base. Push handles are provided between each of the two supporting side plates and the base. A bottom placement plate and a top placement plate are arranged between the two supporting side plates, forming an angle with the supporting side plates. A vertical support plate is connected to the side of the base away from the push handles. The horizontal placement plate is positioned between the bottom placement plate and the vertical support plate. Tool placement holes are provided on the bottom placement plate, the top placement plate, and the horizontal placement plate. The tool holder can be moved by pulling or pushing the push handles between the supporting side plates and the base. The bottom placement plate and the top placement plate are inclined, allowing longer and heavier tools to be placed on the horizontal placement plate. This prevents the tool holder from tipping over due to the inclined placement, utilizing limited space to meet the tool placement requirements.

[0026] 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.

[0027] This utility model provides, for example Figures 1-6 The tool holder for a CNC machine tool shown includes:

[0028] The storage box 1 for storing cutting tools and the transfer device for taking and putting away cutting tools are located at the bottom of the storage box 1.

[0029] The inner cavity of the storage box 1 is provided with two sets of rotatable chain belts 2. The chain belts 2 are movably connected to the movable frame 3 through a movable shaft. The inner side of the movable frame 3 is movably connected to two sets of clamps 4 for clamping and fixing different tools through a movable shaft. The movable frame 3 is provided with an adjustment component 5 for opening and closing the clamps 4.

[0030] The transfer device includes a fixed frame 6 fixed to the bottom of the storage box 1, and a support frame 7 for transferring the tool is slidably arranged inside the fixed frame 6. The support frame 7 can be adjusted up and down inside the fixed frame 6 and the storage box 1.

[0031] First, the tools need to be numbered. A recognition camera is installed at the bottom of storage box 1 to identify the numbers on the tools.

[0032] By matching the cutting tools with the fixture 4, different cutting tools are stored. The rotating chain belt 2 adjusts the position of the movable frame 3 to be directly above the fixed frame 6. Then, the support frame 7 is moved and lifted in the transfer device to realize the transfer of the cutting tools between the fixed frame 6 and the movable frame 3. At the same time, the adjustment component 5 is used to open and close the fixture 4 to realize automatic picking and placing. This not only allows for the storage of different cutting tools, but also reduces the amount of manual work and makes the storage of cutting tools more convenient.

[0033] Among them, such as Figure 1-2 As shown:

[0034] Two sets of rotating shafts 8 are rotatably connected to the two sides of the inner cavity of the storage box 1 via bearings. Two sets of sprockets 9 are fixed to the outer side of the rotating shafts 8. The chain belt 2 is driven and connected to the sprockets 9 on the outer side of the two sets of rotating shafts 8. A first servo motor 10 is fixed to the outer side of the storage box 1. The output shaft of the first servo motor 10 is fixedly connected to the end of one set of rotating shafts 8. The first servo motor 10 drives one set of rotating shafts 8 to rotate. Then the chain belt 2 rotates in cooperation with the other set of rotating shafts 8 and sprockets 9, realizing the alternating change of the position of multiple sets of movable frames 3.

[0035] Furthermore, such as Figure 3 As shown:

[0036] The adjustment assembly 5 includes three sets of connecting shafts 51 rotatably connected to the top of the inner cavity of the movable frame 3 via bearings. An adjustment support plate 52 is fixed to the bottom of each connecting shaft 51, located inside the clamp 4. A traction spring 53 is also fixed to the opposite side of the clamp 4. Both the support spring 53 and the adjustment support plate 52 are connected to the upper end of the inner side of the clamp 4. Adjacent sets of connecting shafts 51 are connected to a connecting belt 55 via a pulley 54. A second servo motor 56 is fixed to the top of the movable frame 3, and the output shaft of the second servo motor 56 is connected to... A set of connecting shafts 51 is fixedly connected to the top. The second servo motor 56 drives the set of connecting shafts 51 to rotate. Then, in conjunction with the pulley 54 and the connecting belt 55, the other two sets of connecting shafts 51 are synchronously driven, so that the adjusting support plate 52 can rotate 90 degrees. The distance between the two sets of clamps 4 is adjusted by the local difference of the connecting shafts 51 at the edge of the adjusting support plate 52. Then, the upper end of the clamp 4 is pulled and moved, and the lower end of the clamp 4 is opened and closed by using the lever principle to realize the clamping and release of the tool.

[0037] Preferred, such as Figure 5-6 As shown:

[0038] A belt conveyor frame 11 is fixed to the bottom of the fixed frame 6. On both sides of the belt on the belt conveyor frame 11, there are outwardly extending fixed plates 12. A limit rod 13 is fixed to the top of the fixed plate 12. The top of the limit rod 13 extends upward to the inner cavity of the fixed frame 6 and passes through the support frame 7. The belt is rotated by the belt conveyor frame 11, and the belt drives the fixed plate 12 to move back and forth. Then the limit rod 13 drives the support frame 7 to move back and forth within the fixed frame 6, so that the tool can move back and forth within the fixed frame 6, which is convenient for the tool to be picked up and put down.

[0039] It is worth noting that, such as Figure 4-5 As shown:

[0040] Electric push rods 14 are installed around the bottom of the fixed frame 6 via mounting bases. The movable end of the electric push rod 14 passes through the fixed frame 6 and contacts the bottom of the support frame 7. The support frame 7, which is transferred to the top of the electric push rod 14, is lifted and adjusted by the electric push rod 14. At the same time, the limiting rod 13 limits the support frame 7 to prevent the support frame 7 from moving forward or backward, which would prevent the support frame 7 from entering or leaving the storage box 1 normally.

[0041] In a further preferred embodiment, such as Figure 2 As shown:

[0042] A limiting groove 15 is provided on the side wall of the inner cavity of the storage box 1. Multiple sets of sliders 16 are slidably arranged in the limiting groove 15. The opposing side of the sliders 16 passes through the sliding groove and is fixedly connected to the chain belt 2. Through the cooperation of the sliders 16 and the sliding groove, the chain belt 2 can be limited to prevent the chain belt 2 from shaking due to the influence of gravity, which would cause the movable frame 3 and the clamp 4 to shake, affecting the stability of the tool storage. At the same time, it provides positioning for the alignment of the support frame 7 and the clamp 4.

[0043] In addition, such as Figure 1 As shown:

[0044] A PLC controller is installed on the outside of the storage box 1. The first servo motor 10, the second servo motor 56, the electric push rod 14 and the belt conveyor frame 11 are all electrically connected to the PLC controller. With the cooperation of the PLC controller, the tool can be transferred step by step according to the programmed instructions, realizing the automated picking and placing of the tool.

[0045] In practical use, when storing the cutting tools, first place the tool on top of the support frame 7 with the number facing upwards. Then, operate the PLC controller. The belt conveyor 11 drives the belt to rotate, moving the fixed plate 12 and the limit rod 13 backwards. The limit rod 13 drives the support frame 7 to move backwards within the fixed frame 6. During the backward movement of the cutting tool, the recognition camera above identifies the number on the top of the cutting tool and controls the first servo motor 10 to start via the PLC controller. The first servo motor 10 drives the rotating shaft 8 to rotate, and then the chain wheel 9 drives the chain belt 2 to rotate, thereby adjusting the position of the movable frame 3. When the corresponding movable frame 3 moves to the fixed frame... After the tool is positioned above the support frame 7, the electric actuator 14 lifts the support frame 7, causing the tool on top of the support frame 7 to move upward into the movable frame 3 and simultaneously into the inner side of the clamp 4. Then, the second servo motor 56 drives the connecting shaft 51 to rotate, and the connecting shaft 51 drives the adjusting support plate 52 to rotate. The adjusting support plate 52 supports the upper end of the clamp 4, causing the lower end of the tool to close and clamp the tool, thus completing the storage of the tool. Conversely, if it is necessary to remove the tool, the corresponding tool orientation is input on the PLC controller, and the device operates in reverse to transfer the tool from the storage box 1 to the fixed frame 6, and then transfers it from the rear end to the front end of the fixed frame 6 through the support frame 7, making it convenient for workers to collect.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
