[0028] Example 1

[0029] This utility model first provides an adapter tool holder, including a tool holder body 100. A tapered hole 110 is opened inside the first end of the tool holder body 100, and a connecting hole 120 is opened at the second end of the tool holder body 100, the connecting hole 120 communicating with the tapered hole 110. The tool holder body 100 also includes an inner pull stud assembly 200, which includes a threaded pull stud 210. The threaded pull stud 210 is disposed at the center of the small end of the tapered hole 110, and the threaded portion of the threaded pull stud 210 faces the tapered hole 110.

[0030] In this embodiment, a connecting hole 120 is provided at the second end of the tool holder body 100, so that a connector can be provided in the connecting hole 120 to connect with the spindle. The connector can be, for example, a pull stud. A tapered hole 110 is provided inside the first end of the tool holder body 100, with the large end of the tapered hole 110 facing outward. An inner pull stud assembly 200 is provided at the small end of the tapered hole 110. The threaded pull stud 210 in the inner pull stud assembly 200 is positioned at the center of the small end of the tapered hole 110 and is limited, with the threaded portion of the threaded pull stud 210 facing the tapered hole 110, thereby allowing the connection to proceed. The threaded pull stud 210 can connect to a specified type of tool holder inserted into the tapered hole 110; and since the tapered hole 110 is connected to the connecting hole 120, the threaded pull stud 210 itself can be replaced from the connecting hole 120. When different types of tool holders need to be connected, different types of threaded pull studs 210 can be replaced to match the tool holder of that type, so that the spindle can match more types of pull studs and tools for production and processing, improving the versatility of machining tool holders, making them adaptable to various processing and production needs, and expanding the production range of machine tools.

[0031] In an alternative embodiment, the inner pull pin assembly 200 further includes a fixing part (not shown) fixed inside the handle body 100, and a threaded pull pin 210 passing through the fixing part; the end of the threaded pull pin 210 facing the connection hole 120 has a screwing part 211.

[0032] In this embodiment, the position of the threaded rivet 210 is fixed by the fixing part, and then the threaded rivet 210 is connected to the specified type of tool holder, which can ensure the connection stability of the tool holder; and the setting of the screwing part 211 facing the outer end of the connection hole 120 allows the user to screw the exposed screwing part 211 through the connection hole to fix the threaded rivet 210 to the threaded connection hole on the specified type of tool holder.

[0033] In one alternative embodiment, the fixing part is configured as a threaded part or a spring clip to fix the position of the threaded pull stud 210. For ease of understanding, the following explanation is provided: for example, when the fixing part is configured as a threaded part, the threaded pull stud 210 passes through the threaded part in a threaded connection and extends into the tapered hole 110 to connect with a specified type of tool holder, which is simple to operate and reliable in connection; or, for example, when the fixing part is configured as a spring clip, it is threadedly connected with the threaded pull stud 210, and thus the threaded pull stud can be clamped and lifted to achieve overall locking based on the conical surface contact.

[0034] In one alternative embodiment, the adapter tool holder further includes a spindle connection portion 300, the first end of which is connected to the connection hole 120, and the second end of which is used to connect to the spindle. In use, the threaded pull pin 210 can be connected and locked first, and then the spindle connection portion 300 can be connected to the connection hole 120, and finally inserted into the spindle for locking.

[0035] In one optional embodiment, the spindle connection 300 includes an external pull pin 310 and a connecting shaft 320 that are interconnected, and the connecting shaft 320 is detachably and fixedly connected to the connecting hole 120; the external pull pin 310 is used to connect to the spindle.

[0036] In this embodiment, the method of connecting the spindle with the external pull pin 310 is more common and suitable for most machining production environments; while the connecting shaft 320 and the connecting hole 120 are detachably fixedly connected, which can realize the disassembly and assembly of the spindle connecting part 300 and ensure the stable connection between the spindle connecting part 300 and the tool holder body 100.

[0037] In one optional embodiment, a limiting part 130 is provided at the connection between the tapered hole 110 and the connecting hole 120, and the limiting part 130 abuts against the side of the threaded rivet 210 facing the tapered hole 110; the end of the connecting shaft 320 can abut against the side of the inner rivet assembly 200 away from the tapered hole 110.

[0038] In this embodiment, the threaded rivet 210 is axially limited by the limiting part 130 to prevent the threaded rivet 210 from falling toward the tapered hole 110. The end of the connecting shaft 320 can abut against the side of the inner rivet assembly 200 away from the tapered hole 110. That is, the side of the threaded rivet 210 away from the tapered hole 110 is limited by the end of the connecting shaft 320. Therefore, the position of the threaded rivet 210 can be fixed without other structural designs. Of course, with the existing fixing part, the connecting shaft 320 may not abut against the inner rivet assembly 200. It can be understood that even with the existing fixing part, the connecting shaft 320 can abut against the inner rivet assembly 200 to achieve a better fixing effect.

[0039] In one optional embodiment, a first flange portion 140 is provided on the outer side of the first end of the tool holder body 100; the first flange portion 140 is provided with a set screw hole 141 communicating with the tapered hole 110 and / or a separation hole 142 communicating with the tapered hole 110.

[0040] In this embodiment, when a set screw hole 141 is provided on the first flange portion 140, the tool holder can be secured by screwing a set bolt into the set screw hole 141, thereby further enhancing the fixing effect on the tool holder in the tapered hole 110. Since the tool is subjected to axial reaction force during machining, a large adhesion force is generated between the tool holder in the tapered hole 110 and the inner wall of the tapered hole 110, making it difficult to directly remove the tool holder from the tapered hole 110. Therefore, when a separation hole 142 communicating with the tapered hole 110 is provided on the first flange portion 140, a separating member can be inserted into the separation hole 142 to generate a force that moves the tool holder toward the large end of the tapered hole 110, thereby easily removing the tool holder from the tapered hole 110. The separating member can be a rod or a bolt, etc. When the separating member is a bolt, the separation hole 142 is a threaded hole.

[0041] In one optional embodiment, a second flange portion 150 is further provided on the outside of the tool holder body 100. The diameter of the second flange portion 150 is larger than that of the first flange portion 140 and it is located on the side of the first flange portion 140 away from the tapered hole 110, thereby shielding the set screw hole 141 and the separation hole 142 on the first flange portion 140. At the same time, a housing 400 is provided on the side of the second flange portion 150 away from the first flange portion 140, and a tool holder information monitoring module 500 is provided inside the housing 400. The second flange portion 150 provides support and fixation for the housing 400 and the tool holder information monitoring module 500 inside the housing 400. The tool holder information monitoring module 500 is used to monitor the status information of the tool holder. Common status information of the tool holder can include stress, axial force, lateral force, pressure, torque, temperature, etc., to monitor the working status of the tool holder in real time, so that the staff can take corresponding measures according to the different working status of the tool holder to improve the molding quality of the final product. The housing 400 protects the various sub-modules or power supply of the tool holder information monitoring module 500.

[0042] In one optional implementation, the tool holder information monitoring module 500 includes, but is not limited to, a pressure monitoring module, a torque monitoring module, a transverse force monitoring module, and a lateral force monitoring module, and the monitoring end of each monitoring module can be directly connected to the side wall of the tool holder body 100; for example, the detection can be performed by bonding strain gauges, and the specific limitations are not made on the bridging method, bonding angle, and strain gauge model parameters; since the tool holder information monitoring module 500 can monitor torque, transverse force, lateral force, etc., the tool setting operation can be realized through real-time monitoring of the above data.

[0043] Example 2

[0044] This utility model also proposes a machining shaft component, including the aforementioned adapter tool holder and machining tool holder 600. An annular groove 610 is provided on the outer side of the machining tool holder 600. The annular groove 610 is located inside the tapered hole 110 and is at least partially connected to the outside. Since the annular groove 610 is connected to the outside, a separating rod can be inserted through the connection to abut against the downwardly inclined side wall in the annular groove 610, thereby separating the machining tool holder 600 from the tapered hole 110. Alternatively, a fastener similar to a bolt can be inserted through the connection and tightened to achieve a good fixing effect on the machining tool holder 600.

[0045] In one optional embodiment, the lower sidewall of the annular groove 610 is an inclined surface. The separation hole 142 in the adapter tool holder corresponds to the lower inclined sidewall of the annular groove 610. A separation rod is inserted into the separation hole 142. After the separation rod abuts against the lower inclined sidewall, it separates the machining tool holder 600 downward, which facilitates the machining tool holder 600 being pulled out of the tapered hole 110. The set screw hole 141 corresponds to the annular groove 610. By screwing a set screw into the set screw hole, the machining tool holder 600 can be effectively fixed.

[0046] In one alternative embodiment, the machining tool holder 600 has an axially extending groove 620, and the tool holder body 100 has a key 160 that is adapted to the groove 620 to provide a limit in the rotational direction. For ease of understanding, the following example is given: the machining tool holder 600 is inserted into the tapered hole 110 such that the outer tapered surface of the machining tool holder 600 mates with the inner tapered surface of the tapered hole 110, while the key 160 engages with the groove 620; then the machining tool holder 600 is locked in place by tightening the threaded pull stud 210; next, the spindle connection part 300 is connected to the connection hole 120; finally, the spindle connection part 300 is connected to the spindle.
