Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to a tooling device for detecting the coaxiality of cutting tools. Background Technology

[0002] In the machining of metal mechanical parts, tool changing is usually done manually by on-site personnel. The coaxiality of the tool during installation can only be checked by dial gauge after the tool is installed on the CNC machine tool. If the coaxiality of the tool is not up to standard, the tool needs to be removed from the CNC machine tool or re-grinded after removal, and then reinstalled on the CNC machine tool. This forms a heavy workload, which not only affects the processing efficiency of the product, but also the frequent tool removal and installation can easily lead to tool confusion, and the length of the tool is difficult to control when locking the tool. Summary of the Invention

[0003] This application provides a tooling device for detecting the coaxiality of cutting tools, which aims to solve at least one of the technical problems existing in the prior art.

[0004] This application also provides a tooling device for detecting the coaxiality of a cutting tool, including a frame assembly, a detection assembly, and a spindle assembly for clamping a tool holder. The spindle assembly and the detection assembly are both mounted on the frame assembly, and the detection assembly is located on one side of the spindle assembly for detecting the coaxiality of the cutting tool fixed on the tool holder.

[0005] The spindle assembly includes a spindle motor, a spindle box, and a tool-removing cylinder. The spindle box has a mandrel for clamping the tool holder. The spindle motor is mounted on the spindle box and is connected to the mandrel for transmission. The tool-removing cylinder is connected to the spindle box and is located on the side of the spindle box away from the detection component, and is used to assist the tool holder in disengaging from the mandrel.

[0006] The technical solution provided in this application embodiment can include the following beneficial effects: This application designs a tooling device for detecting the coaxiality of a cutting tool, which includes a frame assembly, a detection assembly, and a spindle assembly. The spindle assembly is used to clamp and fix the tool holder so that the tool can be quickly clamped by the mandrel through the tool holder. Then, the detection assembly detects the coaxiality of the tool. When the coaxiality of the tool does not meet the requirements, the tool can be removed from the mandrel and reinstalled, or the tool holder and the tool can be removed from the mandrel and re-grinded to ensure the coaxiality of the tool when it is installed on the CNC machine tool through the tool holder. This eliminates the need for repeated tool disassembly and reassembly on the CNC machine tool, simplifies operation, reduces labor time, and improves work efficiency.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] like Figures 1 to 13 As shown, this application provides a tooling device, including a frame assembly 10 and a spindle assembly 20. The spindle assembly 20 is mounted on the frame assembly 10 and is used to clamp a tool holder 200. The tool holder 200 is used to fix a cutting tool 100, so that the cutting tool 100 can be quickly clamped by the spindle 211 through the tool holder 200. This ensures that the repeatability of the cutting tool 100 is within the range of -0.01mm to 0.01mm. At the same time, compared with the traditional method, the cutting tool 100 can be replaced in only 30 seconds. The operation is simple, reducing labor time and improving work efficiency.

[0032] In an optional embodiment, the spindle assembly 20 includes a spindle drive assembly 23, a spindle housing 21, and a tool-changing cylinder 22. The spindle housing 21 has a spindle 211 for holding the tool holder 200. The spindle drive assembly 23 is mounted on the spindle housing 21 and is drively connected to the spindle 211. The tool-changing cylinder 22 is connected to the spindle housing 21 and is located on the side of the spindle housing 21 away from the detection assembly 30. It assists in disengaging the tool holder 200 from the spindle 211 so that the tool holder 200 can be fixed or released during automatic tool changing. The tool holder 200 of the 00 design prevents the tool 100 from retracting during tool locking when it is installed on the CNC machine tool. It also ensures that the tool changing environment of the tool 100 and tool holder 200 in the tooling equipment is consistent with the machining environment of the tool 100 on the CNC machine tool. At the same time, it can also avoid the difficulty in controlling the length of each tool 100 on the CNC machine tool due to different retraction amounts of different tools 100. The design is simple, practical, and effectively improves the efficiency and accuracy of tool 100 replacement.

[0033] For example, when the tool 100 needs to be installed on a CNC machine tool, the tool 100 is fixed on the tool holder 200, and then the tool holder 200 is fixed on the spindle 211 to check the parameters to ensure the accuracy of the tool 100 after it is installed on the CNC machine tool; or the tool holder 200 is fixed on the spindle 211 first, and then the tool 100 is fixed on the tool holder 200, so that the tool 100 can be measured in length and tested for coaxiality by tooling equipment to ensure the accuracy of the tool 100 after it is installed on the CNC machine tool. In this application, the tool holder 200 can be clamped by the mandrel 211, allowing the tool 100 to be measured in length and tested for coaxiality on the tooling equipment. When the installation length of the tool 100 meets the process accuracy and / or the coaxiality of the tool 100 meets the requirements, the entire mechanism of the tool holder 200 and the tool 100 can be removed and installed on the CNC machine tool. This prevents the machining accuracy of the CNC equipment from being affected by inconsistent installation lengths and / or poor coaxiality of the tool 100 after it is installed on the CNC machine tool. It also avoids the tool 100 from being repeatedly disassembled and reassembled on the CNC machine tool. The tooling structure is compact, simple to operate, convenient to use, reduces labor time, improves work efficiency, and has good reliability.

[0034] In an optional embodiment, the spindle 211 is provided with a clamping cavity with a taper of 7:24. The clamping cavity is configured to receive the tool holder 200 for fixing. A pull claw portion may be provided on its inner side. The pull claw portion is drivenly connected to the tool-removing cylinder 22, so that the tool-removing cylinder 22 can drive the pull claw portion to reciprocate, for clamping or releasing the tool holder 200, so that the tool holder 200 can be quickly fixed on or removed from the spindle 211, without affecting the installation length and coaxiality of the tool 100. This ensures the accuracy of the tool 100, together with the tool holder 200, being removed from the spindle 211 and installed on the CNC equipment after calibration.

[0035] In an optional embodiment, the spindle box 21 includes a first bracket 212, the spindle 211 is mounted on the frame assembly 10 via the first bracket 212, the tool-cutting cylinder 22 is fixed at the end of the frame assembly 10 away from the detection assembly 30 and is coaxially arranged with the spindle 211, and the spindle drive assembly 23 is arranged at the upper end of the first bracket 212 for driving the spindle 211 to rotate relative to the first bracket 212, and enabling the spindle drive assembly 23 and the tool-cutting cylinder 22 to be arranged in different directions along the first bracket 212, replacing the existing structure in which the spindle drive assembly 23 and the tool-cutting cylinder 22 are installed sequentially along the axial direction, which can reduce the axial length of the spindle drive assembly 23 and reduce the space occupied by the spindle drive assembly 23. The tool-clamping cylinder 22 is a force-enhancing gas-liquid conversion device. It compresses air to act on the cylinder piston, generating thrust, which in turn pushes the hydraulic cylinder piston. This causes hydraulic pressure, several times higher than the compressed air pressure, to act on the connecting rod within the spindle 211, generating thrust to clamp or release the tool holder 200, thus assisting in the up and down movement of the tool holder 200. When the tool holder 200 is being moved up, the tool-clamping cylinder 22 clamps it tightly via a connecting cylinder; when the tool holder is being moved down, it releases it by blowing air.

[0036] In an optional embodiment, the spindle drive assembly 23 includes a spindle motor 231 and a spindle transmission component 232. The spindle motor 231 is mounted on the upper end of the first bracket 212, and the spindle transmission component 232 is connected between the spindle motor 231 and the spindle 211, enabling the spindle motor 231 to drive the spindle 211 to rotate via the spindle transmission component 232. The spindle transmission component 232 may include, but is not limited to, a belt drive component.

[0037] In an optional embodiment, the spindle 211 is provided with a pull rod and a pull claw. The pull claw is connected to the cutter cylinder 22 through the pull rod, so that the cutter cylinder 22 can tighten or loosen the pull pin 201 of the cutter handle 200 through the pull claw, ensuring that the installation length and coaxiality of the cutter 100 will not change during the disassembly and assembly of the cutter handle 200.

[0038] In an optional embodiment, the tooling equipment further includes a detection component 30, which is mounted on the frame assembly 10 and located on one side of the spindle assembly 20. The detection component 30 is used to detect the coaxiality of the tool 100 fixed on the tool holder 200. When the coaxiality of the tool 100 does not meet the requirements, the tool 100 can be removed from the spindle 211 and reinstalled, or the tool holder 200 and the tool 100 can be removed from the spindle 211 and re-grinded to ensure the coaxiality of the tool 100 when it is installed on the CNC machine tool through the tool holder 200. This eliminates the need for repeated tool disassembly and reassembly on the CNC machine tool, simplifies operation, reduces labor time, and improves work efficiency.

[0039] In an optional embodiment, the tooling device further includes a tool stop assembly 40, which is mounted on the frame assembly 10 and located on the side of the spindle assembly 20 away from the tool holder cylinder 22. The tool stop assembly 40 is used to detect the length of the tool 100 extending out of the tool holder 200, so that the length of the tool 100 installed on the CNC machine tool can be controlled, ensuring that the installation length of the tool 100 is within the accuracy required by the process, and also ensuring that the length of multiple tools 100 installed on the CNC machine tool can be kept consistent, without the need to disassemble and reassemble the tools, and without worrying about the tool 100 retracting when locking the tool.

[0040] In an optional embodiment, the spindle assembly 20 further includes a tool change button 25 for controlling the operation of the tool change cylinder 22. The tool change button 25 is mounted at the lower end of the spindle housing 21 and faces the operator, so that the operator can use the tool change button 25 to mount the tool holder 200 and the cutting tool 100 onto the spindle 211, or to remove the tool holder 200 and the cutting tool 100 from the spindle 211.

[0041] For example, when it is necessary to install the tool holder 200 and the tool 100 onto the spindle 211, press the tool change button 25 to install the tool holder 200 of the tool 100 onto the spindle 211, and then release the tool change button 25 to complete the installation of the tool holder 200. Next, loosen the locking nut on the tool holder 200 and move the tool 100 into the tool holder 200, ensuring that the length of the tool 100 extending out of the tool holder 200 is less than the length of the tool 100 after it is installed on the CNC machine tool, to avoid the tool 100 colliding with the tool stop assembly 40 during the movement. Then adjust the tool stop assembly 40 to the position where the tool 100 needs to be installed on the CNC machine tool. The tool 100 can be manually pulled out from the tool holder 200 and pressed against the tool stop assembly 40, and the tool 100 should be held manually, and then the locking nut should be pre-tightened. After the locking nut is pre-tightened, the tool 100 nut can be tightened using a dedicated tool 100 wrench. After confirming that the length of the tool 100 extending out of the tool holder 200 is correct, the tool stop assembly 40 is reset, that is, the tool stop assembly 40 is moved toward the side away from the spindle 211.

[0042] After the tool holder 200 and the tool 100 are installed on the spindle 211, the length of the tool 100 is checked using a detection function to check the position of the tool 100. If the length of the tool 100 meets the requirements, the coaxiality of the corresponding diameter of the tool 100 is checked using the detection component 30. If the length of the tool 100 does not meet the requirements, the tool 100 on the tool holder 200 is loosened again, the compensation value for the length of the tool 100 is increased, the tool stop component 40 is moved and the tool is relocked, and then the length of the tool 100 is checked again using the detection function to check the position of the tool 100. If the length of the tool 100 meets the requirements, the coaxiality of the tool 100 is checked again. If the coaxiality of the tool 100 does not meet the requirements, the tool 100 can be replaced or the tool 100 together with the tool holder 200 can be removed from the spindle 211 and re-ground to ensure the coaxiality of the tool 100 when it is installed on the CNC machine tool through the tool holder 200. This eliminates the need for repeated tool disassembly and reassembly on the CNC machine tool, simplifies the operation, reduces labor time, and improves work efficiency.

[0043] In an optional embodiment, the spindle box 21 includes a positioning assembly 24. The tool 100 mounting seat of the spindle 211 is provided with a positioning key. The positioning key is symmetrically mounted on the edges of both sides of the tool 100 mounting seat by positioning key locking screws. The positioning assembly 24 is disposed on the first bracket 212 and located on one side of the tool 100 mounting seat so as to cooperate with the positioning key to limit the rotation of the spindle 211 relative to the first bracket 212, thereby realizing the quick replacement or installation of the tool 100.

[0044] For example, the positioning component 24 includes a positioning block 243, a positioning drive 242, and a positioning mounting plate 241 for fixing to the first bracket 212. The positioning mounting plate 241 has a positioning movable groove 2411 and a positioning mounting part. The positioning drive 242 is fixed to the positioning mounting part and connected to the positioning block 243. The positioning block 243 is movably installed in the positioning movable groove 2411 so that the positioning drive 242 can drive the positioning block 243 to extend or retract into the positioning movable groove 2411. When the positioning block 243 extends out of the positioning movable groove 2411, it engages with the positioning key, thereby restricting the rotation of the spindle 211 relative to the first bracket 212. When the positioning block 243 retracts into the positioning movable groove 2411, it releases the engagement with the positioning key, allowing the spindle 211 to rotate freely.

[0045] In an optional embodiment, the spindle box 21 includes an encoder 26 and a code disk 27. The encoder 26 is disposed on the side of the spindle 211 near the tool-changing cylinder 22. The code disk 27 is fixed on the spindle 211 and is used to cooperate with the encoder 26 to detect the rotation angle of the spindle, thereby improving the rotation accuracy of the spindle 211 and ensuring the positioning of the spindle 211 after working in coordination with the detection component 30 during rotation. This facilitates the adjustment of the tool 100 or the re-grinding of the tool 100 when the coaxiality of the tool 100 does not meet the requirements.

[0046] In one optional embodiment, the tool holder 200 includes a tool holder 200 chuck, a tool holder 200 retaining ring, a tool holder 200 connecting seat, a tool holder 200 mounting head, a tool holder 200 small ring, a tool holder 200 large ring, and a tool holder 200 base. The tool holder 200 chuck is installed inside the tool holder 200 retaining ring and above the tool holder 200 connecting seat. The front end of the tool holder 200 connecting seat has a tool holder 200 external thread. The tool holder 200 mounting head is installed at the top of the tool holder 200 base. The tool holder 200 small ring is connected to the bottom of the tool holder 200 connecting seat. The tool holder 200 large ring is connected to the tool holder 200 base. The inside of the tool holder 200 retaining ring has a tool holder 200 internal thread, and the outside of the tool holder 200 retaining ring has a tool holder 200 tooth. The tool holder 200 chuck has a tool holder 200 groove.

[0047] The tool holder 200 retaining ring and the tool holder 200 connecting seat are detachably connected by threads. During clamping, the tool holder 200 chuck and the tool 100 are loosened or secured by rotating the tool holder 200 retaining ring; counterclockwise rotation secures the tool, while clockwise rotation loosens it. The tool holder 200 mounting head is spherical and is installed within the clamping cavity of the spindle 211 for easy positioning, preventing eccentricity of the tool holder 200 and facilitating fixation. The tool holder 200 has six teeth, with dimensions of 20*10*5mm, evenly distributed on the outer side of the tool holder 200 retaining ring, allowing the operator to clamp the tool 100 by manipulating the retaining ring with a wrench. The tool holder 200 connecting seat... The chuck has an internal slope that matches the slope of the mounting bottom of the tool holder 200. This sloped installation method facilitates the installation of the tool holder 200 and prevents the tool holder 200 from tilting, which could cause the tool 100 to be misaligned and result in insufficient machining accuracy. The tool holder 200 has a groove around its edge for secondary fixing. To further secure the tool 100 and prevent it from flying off during rotation, the tool holder 200 has a cylindrical mounting groove at its center. The diameter of this mounting groove is the same as that of the tool 100. The size of the mounting groove at the center of the tool holder 200 varies depending on the model of the tool holder 200. Therefore, different models of tool 100 are paired with different models of tool holder 200.

[0048] Specifically, when using the tool holder 200, the tool 100 is clamped together with the corresponding tool holder 200 chuck, and the tool holder 200 chuck and the tool 100 are fixed on the tool holder 200 connecting seat by the tool holder 200 fixing ring. After fixing, the tool holder 200 mounting head of the tool 100 mounting seat is aligned with the clamping cavity, inserted and clamped.

[0049] In an optional embodiment, the detection component 30 includes an adjustment component 32, a translation component 33, and a sliding component 31 on which a dial indicator 311 is mounted. The sliding component 31 is connected to the adjustment component 32 via the translation component 33. The adjustment component 32 is mounted on the frame component 10 and is used to adjust the height position of the dial indicator 311 so that the dial indicator 311 can match different types of cutting tools 100, each type of cutting tool 100 may have a different diameter.

[0050] In an optional embodiment, the adjusting assembly 32 includes a guide shaft 322, a guide sleeve 321, and an adjusting plate 323. A translation assembly 33 is mounted on the adjusting plate 323. Both ends of the adjusting plate 323 are connected to two guide sleeves 321. The two guide sleeves 321 are correspondingly mounted on two guide shafts 322. The two guide shafts 322 are spaced apart on the frame assembly 10 so that the adjusting plate 323 can move along the direction of the guide shafts 322 through the cooperation of the guide sleeves 321 and the guide shafts 322. This allows adjustment of the height position of the adjusting plate 323 relative to the frame assembly 10, thereby controlling the position of the dial indicator 311 relative to the tool 100. The guide sleeve 321 has an adjusting hole on the side facing away from the adjusting plate 323, and an adjusting screw is installed in the adjusting hole. This screw can be used to lock or loosen the locking state of the guide sleeve 321 relative to the guide shaft 322, thereby adjusting the position of the adjusting plate 323.

[0051] In an optional embodiment, the translation assembly 33 includes a translation drive assembly 331, a translation guide assembly 332, and a translation slider 333. The translation assembly 31 is mounted on the translation slider 333, which is slidably connected to the adjustment plate 323 via the translation guide assembly 332. The translation drive assembly 331 is mounted on the adjustment plate 323 and is used to drive the translation slider 333 to move along the length direction of the adjustment plate 323, so as to control the dial indicator 311 to detect the coaxiality of the tool 100 at any length, ensuring that the coaxiality of the tool 100 remains consistent at any length. The length direction of the adjustment plate 323 is consistent with the extension direction of the mandrel 211 and the length direction of the frame assembly 10.

[0052] In an optional embodiment, the translation drive assembly 331 includes a translation drive motor and a translation belt assembly. The translation belt assembly includes a translation belt, a first translation pulley, and a second translation pulley. The first translation pulley is fixed on the output shaft of the translation drive motor, and the second translation pulley is suspended below the adjusting plate 323 via a translation mounting plate 334. The translation drive motor is suspended on the other side of the adjusting plate 323 via a translation fixing plate. The translation belt connects the first translation pulley and the second translation pulley, and the translation slider 333 is fixed on the translation belt so that the translation drive motor can drive the translation slider 333 to move along the length direction of the adjusting plate 323 via the translation belt.

[0053] In an optional embodiment, the sliding assembly 31 includes a sliding mounting plate 312, a sliding drive motor 313, a sliding guide rail assembly 315, and a dial indicator mounting base 314. The dial indicator mounting base 314 is slidably mounted on the sliding mounting plate 312 via the sliding guide rail assembly 315. The sliding mounting plate 312 is obliquely mounted on the translation slider 333 of the translation assembly 33. The sliding drive motor 313 is mounted on the sliding mounting plate 312 and is used to drive the dial indicator 311 on the dial indicator mounting base 314 to move along the length direction of the sliding mounting plate 312, so that the dial indicator 311 can be tilted relative to the frame assembly 10. The length direction of the sliding mounting plate 312 is perpendicular to the length direction of the adjusting plate 323.

[0054] In an optional embodiment, the translation slider 333 has an inclined first slope with an inclination angle of 43 to 45 degrees relative to the horizontal plane of the frame assembly 10. The sliding mounting plate 312 is mounted on the first slope so that the dial indicator 311 mounted on the dial indicator mounting base 314 can be tilted to 43 to 45 degrees relative to the horizontal plane of the frame assembly 10 to ensure the accuracy of the dial indicator 311 in detecting the coaxiality of the tool 100.

[0055] In an alternative embodiment, the first inclined plane is tilted at an angle of 44 degrees relative to the horizontal plane of the rack assembly 10.

[0056] In an optional embodiment, the tool stop assembly 40 includes a tool stop drive assembly 41, a tool stop arm 42, a touch sensor 43, and a tool stop mounting plate 44 mounted on the frame assembly 10. The touch sensor 43 is mounted on the tool stop arm 42, which is slidably mounted on the tool stop mounting plate 44. The tool stop drive assembly 41 drives the tool stop arm 42 to move along the length direction of the tool stop mounting plate 44, so as to verify and re-inspect the installation length of the tool 100, ensuring that the installation length of the tool 100 is within the accuracy required by the process. The length direction of the tool stop mounting plate 44 is consistent with the length direction of the frame assembly 10.

[0057] In an optional embodiment, the touch sensor 43 includes a contact sensor and a contact block. The contact block is mounted on the side of the contact sensor near the spindle box 21 and is used to contact the tool 100 and transmit the pressure when the tool 100 contacts the contact sensor, thereby realizing the detection of the installation length of the tool 100.

[0058] In an optional embodiment, the tool stop drive assembly 41 includes a servo motor and a lead screw assembly. The servo motor is connected to the lead screw assembly's lead shaft, and the tool stop arm 42 is connected to the lead screw assembly's lead shaft sleeve, so that the servo motor can drive the tool stop arm 42 to move through the lead screw assembly and ensure the accuracy of the tool stop arm 42 during the movement.

[0059] In an alternative implementation, the cutter drive assembly 41 is a linear module motor.

[0060] In an optional embodiment, the tool stop assembly 40 includes a magnetic scale 48 and a reading head 47. The magnetic scale 48 is installed below the tool stop drive assembly 41. The reading head 47 is connected to and corresponds to the tool stop arm 42, and is used to obtain the sliding position of the tool stop arm 42 and feed it back to the linear module motor. This allows the linear module motor to readjust the position of the tool stop arm 42 or reinstall the tool 100 based on the parameters fed back by the reading head 47. Then, the installation length of the tool 100 is re-inspected until it is within the accuracy required by the process. This achieves precise control and detection of the tool 100 length when changing the tool 100 on the CNC machine tool. Combined with the coaxiality detection of the detection assembly 30, the coaxiality of the tool 100 after replacement can be automatically detected, preventing inconsistent installation lengths and poor coaxiality of the tool 100 from affecting the machining accuracy of the CNC machine tool.

[0061] In an optional embodiment, the length of the tool holder 200 can be selected according to the model of the tool 100, that is, the tool holder 200 has different lengths. The tooling equipment can adapt to different lengths of tool 100 and tool holders 200 by detecting the tool stop assembly 40 and the detection assembly 30, so that different lengths of tool holders 200 can be selected to match the corresponding tool 100, ensuring that the installation length of the tool 100 is the same.

[0062] After adopting the above technical solution, since the tool stop drive assembly 41 is a high-precision linear module motor, and the tool stop drive assembly 41 can also distinguish the detection resolution of the tool 100 installation length with 0.1um through the cooperation of the magnetic scale 48 and the reading head 47, and can monitor the position of the linear module motor throughout the process. Among them, the tool stop assembly 40 is also equipped with a high-precision displacement sensor to detect the actual tool installation length of the tool 100 in real time and feed it back to the tooling equipment to compensate for the error generated by the tool 100 during the installation process. After the tool stop assembly 40 obtains the error, it compensates for the previous error and reinstalls the tool 100 so that the final installed tool 100 length meets the process accuracy; at the same time, after the tool 100 length is checked, the detection assembly 30 can automatically detect whether the coaxiality of the tool 100 meets the requirements.

[0063] In an optional embodiment, the cutter block assembly 40 further includes a cable routing chain 46 and a cutter block support plate 45. The cutter block support plate 45 is fixed to the lower end of the cutter block arm 42, one end of the cable routing chain 46 is fixedly connected to the cutter block support plate 45, and the other end of the cable routing chain 46 is movable above the cutter block support plate 45.

[0064] In one optional embodiment, the frame assembly 10 includes a body 11, an air supply assembly 14, and an electrical assembly 15. The body 11 contains a first chamber 11a and a second chamber 11b that are isolated from each other. The air supply assembly 14 is disposed in the first chamber 11a and connected to the pneumatic components of the detection assembly 30 and the spindle assembly 20. The electrical assembly 15 is disposed in the second chamber 11b and connected to the electrical components of the detection assembly 30 and the spindle assembly 20. The pneumatic components of the spindle assembly 20 include, but are not limited to, a tool changer cylinder 22, and the electrical components of the spindle assembly 20 include, but are not limited to, a spindle motor 231, a tool change button 25, and an encoder 26.

[0065] After adopting the above technical solution, due to the different heat generation of various components inside the machine body 11 during the operation of the tooling equipment, such as electrical component 15 which is a component with high heat generation, while air source component 14 and other components have low or no heat generation, interference will occur between electrical component 15 and air source component 14 when they are integrated into the machine body 11. The component with high heat generation will affect the component with low or no heat generation, thus shortening the service life of the component with low or no heat generation. However, this application places the electrical component 15, which has high heat generation, in the second chamber 11b. This not only avoids the heat generated by the electrical component 15 during operation from affecting the operation of the air source component 14 in the first chamber 11a, ensuring that the air source component 14 can operate at a safe operating temperature, but also achieves gas-electric separation, effectively preventing contact between the air source component 14 and the electrical component 15 and / or cables, avoiding related safety accidents, and making the tooling equipment safer and ensuring safe use.

[0066] In an alternative implementation, the rack assembly 10 includes a cooling fan 16 that forces heat out of the second chamber 11b and introduces cool air, thereby enabling the electrical components 15 within the second chamber 11b to operate normally within their specified temperature range.

[0067] In an optional embodiment, the body 11 includes a support frame 111, a support panel 112, and a partition plate. A first chamber 11a and a second chamber 11b are formed within the support frame 111 and separated by the partition plate. The support panel 112 is fixed to the upper end of the support frame 111. The spindle assembly 20, the detection assembly 30, and the blade stop assembly 40 are all mounted on the support panel 112. The spindle assembly 20 and the detection assembly 30 are located at the upper end of the support panel 112, and the blade stop assembly 40 is located at the lower end of the support panel 112 and extends at least partially out of the support panel 112.

[0068] In an alternative embodiment, at least some components of the electrical component 15 are attached to the partition plate so that heat can be dissipated to the surroundings through the partition plate and the housing of the support frame 111, thereby effectively increasing the heat dissipation effect of the heat dissipation structure.

[0069] In an optional embodiment, the frame assembly 10 further includes a display device 13 and an operation button 12. The display device 13 is mounted on the upper end of the machine body 11 and located at the rear end of the spindle assembly 20, while the operation button 12 is mounted on the upper end of the machine body 11 and located at the front end of the spindle assembly 20. The operation button 12 is at least partially used to control the operation of the tool stop assembly 40, so that the tool stop assembly 40 can detect the installation length of the tool 100 according to the corresponding tool length button.

[0070] In one optional embodiment, the support panel 112 is provided with a first mounting part, a second mounting part, a third mounting part and a fourth mounting part. The spindle assembly 20 is mounted in the middle of the support panel 112 via the first mounting part. The detection assembly 30 is mounted on one side of the support panel 112 via the second mounting part and is close to the rear of the support panel 112. The tool stop assembly 40 is mounted on one side of the support panel 112 via the third mounting part and is located in front of the detection assembly 30. The operation button 12 is located on the side of the tool stop assembly 40 facing away from the detection assembly 30. The display device 13 is mounted on the side of the support panel 112 facing away from the detection assembly 30 via the fourth mounting part and is located at the rear of the support panel 112.
