[0002] In the operation of a machining center, the tool magazine, as the core component for storing and switching tools, directly affects tool changing efficiency, machining accuracy, and equipment operational stability due to its precise installation and fixation. Existing tool magazine fixing structures have the following shortcomings:

[0003] Especially when precise angular alignment of the tool magazine with the machine tool spindle (or tool holder) is required, traditional methods lack effective real-time detection and quantitative feedback mechanisms. Even minor angular deviations during installation can lead to tool change failures, tool collisions, or decreased machining accuracy. Furthermore, existing tool magazine base structures are functionally limited, typically providing only simple support and bolt fixation, lacking integrated rapid positioning, angle fine-tuning, and error-proofing designs.

[0004] Therefore, there is an urgent need for a tool magazine fixing structure that can achieve fast, accurate, and efficient installation, and has automatic angle detection and calibration functions. Utility Model Content

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.

[0030] Please see Figure 1-6 This utility model provides a technical solution for a tool magazine fixing structure for a machining center: a tool magazine fixing structure for a machining center includes a positioning base plate 1, a positioning component 2, an infrared transmitter 3, a tool gripper 4, and a tool magazine component 5. The positioning component 2 is connected to the right side of the positioning base plate 1, the infrared transmitter 3 is installed at the bottom of the tool gripper 4, and the tool magazine component 5 is installed at the top of the positioning base plate 1.

[0031] The positioning component 2 includes a plug-in block 21, a first connecting arm 22, a point infrared receiver 23, a bearing 24, a shaft seat 25, a fixed arm 26, a second connecting arm 27, a second fixing hole 28, and a strip infrared receiver 29. The right end of the plug-in block 21 is fixedly connected to the first connecting arm 22, and the right side of the first connecting arm 22 is fixedly connected to the point infrared receiver 23. The bottom of the outer wall of the point infrared receiver 23 is fitted with a bearing 24, and the bottom of the outer wall of the bearing 24 is fitted with a shaft seat 25. The front end of the shaft seat 25 is fixedly connected to the fixed arm 26, and the second fixing hole 28 is opened inside the fixed arm 26. The right end of the point infrared receiver 23 is fixedly connected to the second connecting arm 27, and the right end of the second connecting arm 27 is fixedly connected to the strip infrared receiver 29. The plug-in block 21 is plugged into the positioning base plate 1.

[0032] The positioning base plate 1 includes a support plate 11, a positioning component connecting groove 12, a limiting frame 13, a tool magazine positioning hole 14, a fixing plate 15, and a fixing hole 16. The positioning component connecting groove 12 is provided in the middle right side of the top surface of the support plate 11. The limiting frame 13 is provided at the top edge of the support plate 11. The tool magazine positioning hole 14 is provided on the front and rear sides of the top of the support plate 11. The tool magazine positioning hole 14 is located inside the limiting frame 13. The fixing plate 15 is provided on both the front and rear sides of the support plate 11, and the fixing hole 16 is provided inside the fixing plate 15. The plug-in block 21 is plugged into the positioning component connecting groove 12. The tool magazine component 5 is fixed to the top of the support plate 11.

[0033] The support plate 11, the limiting frame 13 and the fixing plate 15 are integrally formed; the left side of the limiting frame 13 is hollowed out, which facilitates the insertion of the tool magazine housing 51 into the limiting frame 13 from the left side;

[0034] The tool magazine assembly 5 includes a tool magazine housing 51 and a second fixing plate 52. The second fixing plate 52 is located on the bottom of both the front and rear sides of the tool magazine housing 51. The second fixing plate 52 has a fixing hole 521 inside. When the tool magazine housing 51 is installed, the right side of the tool magazine housing 51 and the front and rear sides of the second fixing plate 52 are flush with the inner wall of the limiting frame 13, and the fixing hole 521 is vertically aligned with the tool magazine positioning hole 14. A fan-shaped tool holder 53 is located inside the tool magazine housing 51, and the right end of the fan-shaped tool holder 53 is fixed... A rotating cover 54 is provided, and a drive motor 55 is installed on the top of the tool magazine housing 51. The output shaft of the drive motor 55 is connected to the fan-shaped tool holder 53. When the fan-shaped tool holder 53 rotates and extends out of the tool magazine housing 51, a point infrared receiver 23 is set at the bottom of the rotating circumference of the fan-shaped tool holder 53 with its infrared receiving surface facing upward. It can receive infrared signals emitted vertically downward from the tool gripper 4. The position of the point infrared receiver 23 is set according to the radius of the fan-shaped tool holder 53 to ensure the accuracy of subsequent offset detection.

[0035] The plug-in block 21 is square in shape, and the inner wall of the positioning component connecting groove 12 fits against the plug-in block 21. The plug-in block 21 is square in shape to prevent rotation between the support plate 11 and the plug-in block 21.

[0036] Connecting arm 22 and fixing hole 28 are arranged in a straight line, and fixing hole 28 is perpendicular to the strip infrared receiver 29. When the infrared transmitter 3 is vertical to the dot infrared receiver 23, the infrared transmitter 3 moves straight to the right past the strip infrared receiver 29. According to the position of the infrared light signal received by the strip infrared receiver 29, the infrared light signal received by the strip infrared receiver 29 is located on the extension line of connecting arm 27, so the angle is accurate and no offset is required.

[0037] If the position of the received infrared light signal deviates from the center, the angle deviation can be calculated based on the direction and distance of the deviation. When the infrared light signal appears in front of the extension line of the connecting arm 27, it indicates that the angle of the current strip infrared receiver 29 has a backward deviation, that is, the angle of the support plate 11 has a forward deviation.

[0038] By detecting the precise location of the light signal on the strip infrared receiver 29 and combining this with the known distance between the dot infrared receiver 23 and the strip infrared receiver 29, the system can deduce the accurate angular offset, providing precise numerical data for subsequent automatic calibration or manual adjustment. Specifically:

[0039] Taking the vertical point from the point infrared receiver 23 to the strip infrared receiver 29 as one side (i.e., the direction of connecting arm 27), and the line connecting the vertical point of the point infrared receiver 23 and the strip infrared receiver 29 to the position on the strip infrared receiver 29 that receives the light signal as the other side, and the trajectory of the infrared transmitter 3 moving from the state of triggering the point infrared receiver 23 to receiving the infrared light signal from the strip infrared receiver 29 as the hypotenuse, a right triangle is formed. Knowing the lengths of the two sides with right angles, the angle between the hypotenuse and connecting arm 27 can be calculated, i.e., the offset angle.

[0040] A connector 31 is installed on the top of the infrared transmitter 3. The connector 31 is a workpiece adapted to the machine tool gripper 4. The connector 31 and the infrared transmitter 3 are locked together by bolts. The infrared transmitter 3 and the connector 31 are arranged in the same vertical line, which facilitates the connection between the infrared transmitter 3 and the tool gripper 4. In this embodiment, the tool gripper 4 is arranged vertically, and the tool gripper 4 is controlled to move horizontally by the horizontal actuator 6 of the machine tool.

[0041] The infrared transmitter 3 and the point infrared receiver 23 are mature infrared technologies, and their working principles will not be explained in detail here.

[0042] The strip infrared receiver 29 uses a Hamamatsu S8381-512Q linear array sensor;

[0043] The infrared transmitter 3, the dot infrared receiver 23, and the strip infrared receiver 29 are equipped with built-in batteries and chips, and can be wirelessly connected to external control devices to facilitate the transmission of data to external terminals (such as mobile phones, calculators, etc.) for data display and calculation.

[0044] The positioning component connecting groove 12 is equipped with a filling block 121, and the filling block 121 fits against the inner wall of the positioning component connecting groove 12. After the tool magazine assembly 5 is installed and the positioning component 2 is removed, the filling block 121 seals the positioning component connecting groove 12 to prevent dust from accumulating inside the positioning component connecting groove 12.

[0045] The implementation principle of this application embodiment is as follows:

[0046] Connect the infrared transmitter 3 to the connector 31, and connect the connector 31 to the tool chuck 4 of the machine tool. Then, place the positioning base plate 1 on the plane where the tool magazine needs to be installed. Insert the plug block 21 of the positioning component 2 into the positioning component connecting groove 12 of the positioning base plate 1. Then, control the tool chuck 4 of the machine tool to move to the tool changing position. By moving the positioning base plate 1 and the positioning component 2, the point infrared receiver 23 is positioned vertically below the infrared transmitter 3, and the point infrared receiver 23 receives the light signal from the infrared transmitter 3. Then, according to the position of the second fixing hole 28 on the fixing arm 26, a temporary fixing hole is opened on the worktable to fix the fixing arm 26, that is, to fix the position of the point infrared receiver 23.

[0047] Then, the transverse actuator 6 of the machine tool is controlled to drive the tool gripper 4 to move laterally to the right, and the infrared transmitter 3 moves linearly to the right past the strip infrared receiver 29. Based on the position of the infrared light signal received by the strip infrared receiver 29, the offset angle is calculated. Since the bottom of the point infrared receiver 23 is supported by the bearing 24, the positioning base plate 1 is rotated with the point infrared receiver 23 as the center according to the offset angle. After rotating to the required angle, the offset angle test is repeated until the infrared light signal received by the strip infrared receiver 29 is located on the extension line of the connecting arm 27. Then the angle is accurate, and the positioning of the support plate 11 is completed.

[0048] Bolt holes are made at the positions of fixing holes 16 on the front and rear sides of the fixing plate 15. After the bolt holes are made, the positioning component 2, infrared transmitter 3 and connector 31 are disassembled and the tool magazine component 5 is installed.

[0049] Fix the fixing plate 15 to the workbench with bolt holes. Then place the tool magazine housing 51 on the support plate 11. The right side wall of the tool magazine housing 51 and the fixing plate 2 52 are both in contact with the inner wall of the limit frame 13. Fix the fixing plate 2 52 to the tool magazine positioning hole 14 with bolts to complete the precise positioning and installation of the tool magazine.

The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

The power supply is also common knowledge in the field.
