However, existing tool holders have poor versatility, cannot install other types of tools, and tool replacement is complicated, time-consuming, labor-intensive, and results in low production efficiency. Utility Model Content
[0004] To improve the ease of tool changing, this application provides a tool holder for easy tool changing.
[0005] The tool holder for convenient tool changing provided in this application adopts the following technical solution:
[0006] A tool holder for easy tool replacement includes a body with a tool mounting port. A locking component is provided inside the tool mounting port on the body. A drive component for controlling the locking component is also provided on the body. The tool mounting head is inserted into the tool mounting port and locked to the body by the locking component.
[0007] By adopting the above technical solution, the tool holder body has a tool mounting port for inserting a tool mounting head, and the drive component can control the locking component to lock the tool mounting head on the body, thus improving the overall convenience of tool replacement.
[0008] Preferably, the locking assembly includes a locking sleeve, a locking movable rod, and a locking retractable sleeve. The locking sleeve is installed on the body at the tool mounting opening, and the inner recess of the locking sleeve fits against the inner wall of the tool mounting opening. The locking movable rod is inserted into the inner recess of the locking sleeve and can reciprocate along the depth direction of the tool mounting opening. The locking retractable sleeve is installed on the body inside the tool mounting opening and is fitted onto the locking movable rod. The movement of the locking movable rod causes the locking retractable sleeve to open or close.
[0009] By adopting the above technical solution, the locking sleeve fits snugly against the inner wall of the tool mounting opening to stably support the locking structure. The locking movable rod moves back and forth along the depth direction of the tool mounting opening, causing the locking shrink sleeve fitted on it to open or close, thereby realizing the locking and unlocking of the tool mounting head and improving the convenience of tool replacement.
[0010] Preferably, the locking movable rod is provided with an opening inclined surface one, and the locking contraction sleeve is provided with an opening inclined surface two on the side near the locking movable rod. The opening inclined surface two can move along the inclination direction of the opening inclined surface one. When the locking movable rod is locked, the locking contraction sleeve opens or closes under the cooperation of the opening inclined surface two and the opening inclined surface one.
[0011] By adopting the above technical solution, the locking movable rod is provided with an opening inclined surface one that cooperates with the opening inclined surface two on the locking contraction sleeve, so that the locking contraction sleeve can open or close when the locking movable rod moves by the cooperation of the two inclined surfaces, which improves the convenience of tool installation and disassembly, and thus improves the convenience of tool replacement.
[0012] Preferably, the driving assembly includes a driving lifting block and a driving member. The driving member is mounted on the body, and a driving sliding groove is formed in the body. The driving sliding groove communicates with the tool mounting port. The driving lifting block is slidably disposed in the driving sliding groove. The driving member is located on one side of the driving lifting block. The side of the driving lifting block away from the driving member cooperates with a locking movable rod. The driving member drives the driving lifting block to move in the direction of the locking movable rod, so that the locking movable rod rises in the tool mounting port.
[0013] By adopting the above technical solution, the drive sliding groove inside the body allows the lifting block to slide, and the drive component can drive the lifting block to move towards the locking movable rod, thereby raising the locking movable rod in the tool mounting port, realizing the unlocking of the tool mounting head, and improving the convenience of tool replacement.
[0014] Preferably, the driving component includes a driving eccentric wheel and a driving locking rod. The main body has a driving hole communicating with the driving sliding groove. The driving eccentric wheel is inserted into the driving hole. The driving lifting block has a positioning hole for the shaft of the driving eccentric wheel to be inserted.

The driving locking rod is threaded to the main body. The driving locking rod has an unlocking notch for the driving eccentric wheel to rotate. The side wall of the driving eccentric wheel has a clearance notch for the driving locking rod to be embedded.
[0015] By adopting the above technical solution, the driving component adopts a structure of driving eccentric wheel and driving locking rod. By utilizing the eccentric rotation of the driving eccentric wheel in the driving hole and the positioning hole and eccentric groove of the driving lifting block, the movement of the driving lifting block can be easily controlled, thereby making it easier to control the lifting and lowering of the locking rod, and ultimately improving the convenience of tool replacement; at the same time, the driving locking rod is used to lock or unlock whether the driving eccentric wheel can rotate.
[0016] Preferably, a wedge is provided at the bottom of the locking movable rod, and an inclined surface is provided at the bottom of the wedge. When the driving lifting block moves toward the locking movable rod, the locking movable rod can be lifted upward by being guided by the inclined surface of the wedge.
[0017] By adopting the above technical solution, when the driving lifting block moves towards the direction of the locking moving rod, the guiding effect of the inclined surface at the bottom of the wedge block can make the locking moving rod rise. The movement of the locking moving rod can open or close the locking shrink sleeve, thereby facilitating the installation and removal of the tool and improving the convenience of tool replacement.
[0018] Preferably, a positioning component is provided at one end of the main body, and the main body is mounted on the cutter head through the positioning component; the positioning component includes a positioning plate and a plurality of positioning sliders, a plurality of positioning grooves are provided on the positioning plate, the positioning sliders are slidably disposed in the positioning grooves, and the positioning sliders can slide along the positioning grooves and protrude from the side wall of the positioning plate.
[0019] By adopting the above technical solution, a positioning component is set at one end of the main body. Using a positioning plate and a positioning slider that can slide in the positioning groove, the positioning slider can slide along the positioning groove and protrude from the side wall of the positioning plate. This makes it easier for the tool holder to be accurately installed on the tool disc through the positioning component, which helps to improve the stability of the tool holder installation and the stability of the tool during subsequent use, and further improves the convenience of tool replacement.
[0020] Preferably, the bottom of the positioning groove is inclined, and the sidewall of the positioning slider that contacts the bottom of the groove is in contact with the inclined bottom of the positioning groove. The positioning assembly also includes a plurality of sliding bolts, the number of which is the same as the number of positioning sliders. The sliding bolts are threadedly connected to the positioning plate and inserted into the positioning groove. One end of the sliding bolt located in the positioning groove is threadedly connected to the positioning slider. The sliding bolts are screwed to allow the positioning slider to slide within the positioning groove. A positioning block is fitted onto one end of the sliding bolt that protrudes from the positioning plate. A retaining ring is provided between the positioning block and the positioning plate. A retaining ring groove is provided at the end of the sliding bolt for the retaining ring to engage.
[0021] By adopting the above technical solution, the tool holder can utilize the inclined positioning groove bottom and the positioning slider in contact with each other, as well as the tightening of the sliding bolts, to allow the positioning slider to slide within the positioning groove, thereby improving the convenience of installing the tool holder on the tool disc through the positioning assembly, and further improving the convenience of tool replacement.
[0022] In summary, this application includes at least one of the following beneficial technical effects:

Figure 1 The tool holder for easy tool changing includes a body 1, a tool mounting port 2 on the body 1, a locking component 3 located inside the tool mounting port 2, and a drive component 4 for controlling the locking component 3 on the body 1. The tool mounting head is inserted into the tool mounting port 2 and locked onto the body 1 by the locking component 3. A positioning component 5 is provided at one end of the body 1, and the body 1 is mounted on the tool disc through the positioning component 5.
[0036] The tool holder body 1 has a tool mounting port 2 for inserting a tool mounting head. The drive component 4 controls the locking component 3 to lock the tool mounting head onto the body 1, thus improving the overall ease of tool replacement. A positioning component 5 is provided at one end of the body 1, which facilitates precise installation of the tool holder onto the tool disc, improving the stability of the tool holder installation and subsequent tool use, further enhancing the ease of tool replacement.
[0037] Reference Figure 1 and Figure 2The locking assembly 3 includes a locking sleeve 31, a locking movable rod 32, and a locking retractable sleeve 33. The locking sleeve 31 is installed on the body 1 at the tool mounting port 2. In this embodiment, the locking sleeve 31 is a structure with a groove and an opening at the bottom of the groove, so the inner recess of the locking sleeve 31 fits against the inner wall of the tool mounting port 2. The locking movable rod 32 is inserted into the inner recess of the locking sleeve 31 and can reciprocate along the depth direction of the tool mounting port 2. The locking retractable sleeve 33 is installed on the body 1 inside the tool mounting port 2, and a step is provided inside the tool mounting port 2 for the locking retractable sleeve 33 to be mounted. The locking retractable sleeve 33 is fitted on the locking movable rod 32, and the locking movable rod 32 reciprocates along the depth direction of the tool mounting port 2.
[0038] Figure 2 and Figure 3 The locking movable rod 32 is provided with an opening inclined surface 321, and the locking contraction sleeve 33 is provided with an opening inclined surface 331 on the side near the locking movable rod 32. The opening inclined surface 331 can move along the inclined direction of the opening inclined surface 321. When the locking movable rod 32 is locked, the locking contraction sleeve 33 opens or closes through the cooperation of the opening inclined surface 331 and the opening inclined surface 321, thereby locking or unlocking the tool.
[0039] Reference Figure 2 and Figure 4 The drive assembly 4 includes a drive lifting block 41 and a drive component 42. The drive component 42 is mounted on the body 1. A drive sliding groove 11 is provided inside the body 1. The drive sliding groove 11 communicates with the tool mounting port 2.

The drive lifting block 41 is slidably disposed in the drive sliding groove 11. The drive component 42 is located on the side of the drive lifting block 41 away from the locking movable rod 32. The side of the drive lifting block 41 away from the drive component 42 cooperates with the locking movable rod 32. Specifically, a wedge block 322 is integrally formed at the bottom of the locking movable rod 32. An inclined surface is provided at the bottom of the wedge block 322. When the drive lifting block 41 moves toward the locking movable rod 32, the locking movable rod 32 can be lifted upward by being guided by the inclined surface of the wedge block 322.
[0040] Reference Figure 4 and Figure 5 The driving component 42 includes a driving eccentric wheel 421 and a driving locking rod 422. The body 1 has a driving hole 12 communicating with the driving sliding groove 11 (e.g., Figure 2The drive eccentric wheel 421 is inserted into the drive hole 12. The drive lifting block 41 has a positioning hole 411 for inserting the shaft of the drive eccentric wheel 421. The drive lifting block 41 has an eccentric groove 412 on the inner wall of the positioning hole 411 for the eccentric rotation of the drive eccentric wheel 421. When the drive eccentric wheel 421 is rotated, the eccentric part of the eccentric wheel moves in the eccentric groove 412 and abuts against the inner wall of the eccentric groove 412 in the length direction of the drive sliding groove 11, thereby moving the drive lifting block 41 toward one side of the locking movable rod 32.
[0041] The drive locking rod 422 is threaded onto the body 1. The drive locking rod 422 has an unlocking notch 4221 for rotating the drive eccentric wheel 421.

The sidewall of the positioning slider 52 that contacts the bottom of the groove is in contact with the bottom of the inclined positioning groove 511. The positioning sliders 52 can slide along the positioning grooves 511 and protrude from the sidewall of the positioning plate 51.
[0043] The positioning assembly 5 also includes several sliding bolts 53, the number of which is the same as the number of positioning sliders 52. The sliding bolts 53 are threaded onto the positioning plate 51 and inserted into the positioning groove 511. One end of the sliding bolt 53 located in the positioning groove 511 is threadedly connected to the positioning slider 52. A positioning block 54 is fitted onto the end of the sliding bolt 53 protruding from the positioning plate 51. A retaining ring 55 is provided between the positioning block 54 and the positioning plate 51. A retaining ring groove 531 is provided at the end of the sliding bolt 53 for the retaining ring 55 to engage. The sliding bolts 53 are screwed on to gradually unscrew the positioning sliders 52.
[0044] The implementation principle of a convenient tool holder for tool replacement according to an embodiment of this application is as follows: When a tool needs to be replaced, the operator rotates the drive locking rod 422, aligning the unlocking notch 4221 with the drive eccentric wheel 421. The drive eccentric wheel 421 rotates, causing the drive lifting block 41 to move to one side of the locking movable rod 32. This causes the locking movable rod 32 to rise, unlocking the tool and allowing for the replacement of a new tool. Then, reversing the above steps will lock the new tool. Rotating the drive eccentric wheel 421 will unlock the tool, improving the convenience of tool replacement.
[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
