[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1 to 5 A tool magazine device for tool changing includes a base 1, on which a horizontal drive assembly is mounted, a base plate 2 is mounted on the drive end of the horizontal drive assembly, and a rotary drive assembly 3 is mounted on the base plate 2.

[0026] A mounting cover assembly is installed on the side of the base plate 2, and a tool clamping assembly is rotatably installed inside the mounting cover assembly. The driving end of the rotary drive assembly 3 is connected to the tool clamping assembly.

[0027] When in use, this device can move the base plate 2, which in turn moves the rotary drive assembly 3 and the mounting cover assembly above the base plate 2, thereby moving the tool clamping assembly. The rotary drive assembly 3 can rotate the tool clamping assembly, making it easier to change the tool held on the tool clamping assembly. This increases the stability of the tool changing process and improves processing efficiency, solving the problem of poor stability in the tool changing process and its impact on processing efficiency in the prior art.

[0028] Furthermore, the horizontal drive assembly includes a cylinder 6 fixedly mounted on the base 1, two slide rails 7 disposed on the base 1, two sliders 8 slidably disposed on the corresponding slide rails 7, and a connecting plate 9 disposed on the drive end of the cylinder 6. The base plate 2 is disposed at the top of the two sliders 8, and the connecting plate 9 is fixedly connected to the bottom of the base plate 2. Driven by the cylinder 6, it can provide fast and stable linear motion. The structure of the double slide rails 7 and sliders 8 ensures that the base plate 2 moves smoothly without shaking, improving positioning accuracy. The connecting plate 9 is fixedly connected to the base plate 2, and can drive the base plate 2 to move when the cylinder 6 drives the connecting plate 9 to move.

[0029] Furthermore, two positioning detection components 23 are provided on one side of the base plate 2, and the two positioning detection components 23 correspond to the positions of the mounting cover assembly. Through the two positioning components, one of them can detect whether the cylinder 6 moves to the accurate position when it drives the base plate 2 to move, and whether the base plate 2 returns to its original position when the cylinder 6 resets.

[0030] The positioning detection component 23 consists of a housing for protecting internal components and fixing them to the equipment, a movable contact mounted on the housing, a detector located on one side of the movable contact, and a contact plate mounted on the base 1. The movable contact contacts the contact plate, and the detector detects whether the movable contact has shifted. If shift occurs, it indicates that the predetermined position has been reached. This positioning detection component 23 is existing technology and will not be described in detail here.

[0031] Furthermore, the rotary drive assembly includes a dual-axis reducer and a rotary motor mounted above the base plate 2. The drive end of the rotary motor is connected to the dual-axis reducer (e.g., a dual-output-shaft worm gear reducer). One of the rotating shafts of the dual-axis reducer is connected to the tool clamping assembly via a transmission assembly. The other rotating shaft of the dual-axis reducer is equipped with a speed detection assembly. The transmission assembly includes a connecting block 10 mounted at the drive end of the rotary drive assembly 3, two rollers 11 mounted on one side of the connecting block 10, a rotating rod 5 rotatably mounted inside the mounting cover assembly, and a fixed mounting... A turntable 12 is placed on the outer periphery of the rotating rod 5, and several transmission grooves 13 are opened on one side of the turntable 12. The two rollers 11 are adapted to the transmission grooves 13. The double rollers 11 and the transmission grooves 13 improve the reliability of power transmission and reduce the risk of slippage. The dual-axis reducer can be driven to rotate by a rotary motor. When the connecting block 10 is driven to rotate by the dual-axis reducer, the rollers 11 are driven into the transmission grooves 13 to drive the turntable 12 to rotate and drive the rotating rod 5 to rotate. The rolling friction of the rollers 11 reduces wear and extends service life. The structure is compact and suitable for high-precision indexing motion.

[0032] Furthermore, the rotational speed detection component includes a mounting plate 17 disposed on one side of the rotary drive component 3. A washer 18 is also installed between the mounting plate 17 and the rotary drive component 3. Another rotating shaft of the rotary drive component 3 movably passes through the mounting plate 17 and is connected to a sensing wheel 20. Two mounting brackets 21 are disposed on one side of the mounting plate 17. A vertical laser speed sensor 22 and a horizontal laser speed sensor 22 are respectively mounted on the two mounting brackets 21. The sensing wheel 20 can be driven to rotate by the rotary drive component 3. The vertical and horizontal laser speed sensors monitor the rotational speed in real time to ensure rotational accuracy. The sensing wheel 20 provides non-contact detection, avoids mechanical wear, and improves long-term reliability. The redundant design of the dual laser speed sensors enhances data accuracy. The washer 18 can protect the surface of the rotary drive component and extend its service life.

[0033] The laser rotation speed sensor 22 detects rotation speed by emitting a laser pulse and measuring the time it takes for the laser to travel from emission to reflection, thereby determining the position of a point on the surface of the rotating object. By continuously measuring the position change, the rotation speed of the rotating object is calculated. This laser rotation speed sensor 22 is existing technology and will not be described in detail here.

[0034] Furthermore, the tool clamping assembly includes a tool disc 14 disposed on one side of the rotating rod 5 and several tool clips 15 disposed on one side of the tool disc 14. One side of the tool clip 15 is provided with a clamping opening 16. The tool can be placed into the clamping opening 16 through the clamping opening 16. Because the tool clip 15 is made of a composite flexible material (including: polyurethane material and carbon fiber reinforced plastic, etc.), the tool clip 15 has good elasticity and can clamp the tool into the clamping opening 16.

[0035] Furthermore, the mounting cover assembly includes a hat cover 19 fixedly mounted on one side of the base plate 2 and a rotating cover 4 rotatably mounted on one end of the rotating rod 5. An outlet 25 is provided on one side of the hat cover 19, and the rotating cover 4 is adapted to the outlet 25. The hat cover 19 provides protection to prevent chips and coolant from entering the internal mechanism. In use, the rotating cover 4 can be manually rotated to open the outlet 25, ensuring smooth tool entry and exit, while reducing external interference. The overall structure is compact and optimizes the space layout.

[0036] Furthermore, a protective cover 24 is installed on the base 1. The protective cover 24 can protect the horizontal drive component and prevent dust from affecting the service life of the horizontal drive component.

[0037] 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.
