[0031] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0032] It should be noted that the terms "first", "second" and "third" in the embodiments of the present invention are only used for distinction and do not impose any restrictions on quantity or order. "Multiple" means at least two.

[0033] like Figure 1 and Figure 2 As shown, the first embodiment of the present invention provides a mounting fixture, which includes: an axle seat 1 , a first arm 2 , a second arm 3 and a first positioning pin 5 .

[0034] The shaft seat 1 is provided with a shaft hole, and a plurality of positioning holes arranged at intervals are provided on the end surface of the shaft seat 1 where the shaft hole is provided. The positioning holes can be Figure 1 as well as Figure 2 The first positioning hole 13 or the second positioning hole 14 shown. In actual use, the shaft seat 1 can be set on the tool magazine bracket 82 (please refer to Figure 3 Under the condition that the base plate 7 is provided, the shaft seat 1 is provided on the base plate 7, and the base plate 7 is fixed to the tool magazine support 82 or the column by fasteners, so that the shaft seat 1 is provided on the tool magazine support 82 or the column through the base plate 7. The fasteners can be threaded connectors.

[0035] Please continue reading Figure 1 One end of the first arm 2 is hinged to the shaft seat 1 and can rotate around the axis of the shaft hole. The end of the first arm 2 away from the shaft seat 1 can be used as a handle for the operator to hold; a first hook structure 21 is provided between the two ends of the first arm 2. One end of the second arm 3 is provided with a second hook structure 31, and the other end of the second arm 3 is used to connect an external component, which can be Figure 3 as well as Figure 4 The tool magazine tension spring 83 is shown. The second arm 3 is connected to the first arm 2 through the connection between the first hook structure 21 and the second hook structure 31.

[0036] The first locating pin 5 is inserted into any locating hole on the end surface of the shaft seat 1. It should be understood that "any" does not necessarily mean a single locating pin. In practice, multiple first locating pins 5 may be inserted into different locating holes. When the first locating pin 5 is inserted into the locating hole, it is positioned in the rotation path of the first arm 2, preventing further rotation. For example, the first locating pin 5 may be positioned on the side of the first arm 2 that is relatively far from the second arm 3, preventing further clockwise rotation of the first arm 2.

[0037] The first positioning pin 5 acts as a limit for the first arm 2. The first positioning pin 5 is inserted into the positioning hole. Specifically, the first positioning pin 5 passes through a first positioning hole 13 and a second positioning hole 14 that is opposite to the first positioning hole 13. The first positioning pin 5 blocks the further rotation of the first arm 2, so that the first arm 2 can only rotate to the side in front of the first positioning pin 5 (here Figure 2 ), preventing the first arm 2 from rotating clockwise and falling down (here Figure 2 on the right side of the ).

[0038] Once the position of the first arm 2 around the shaft seat 1 is determined, the first locating pin 5 is inserted sequentially through the locating holes on the two end surfaces of the shaft seat 1 to position the first arm 2. The provision of multiple locating holes allows the first arm 2 to be restrained in different rotational positions, thereby adapting to different machine tool specifications or tool magazine tension springs 83. After the first arm 2 rotates to the appropriate position, the first locating pin 5 is inserted into the locating hole to restrain the first arm 2.

[0039] Using the mounting fixture in the embodiment of the present invention, one end of the first arm 2 is hinged to the shaft seat 1, and a first hook structure 21 is provided on the first arm 2, and a second hook structure 31 is provided on one end of the second arm 3, and the first hook structure 21 is connected to the second hook structure 31. When the first arm 2 rotates around the shaft seat 1, the first arm 2 can push or pull the second arm 3, so that the other end of the second arm 3 pulls the external component. The first locating pin 5 is inserted into the locating hole, so that after the first arm 2 rotates to a suitable position, the first locating pin 5 can limit the first arm 2, thereby being suitable for machine tools or tool magazine tension springs 83 of different specifications. In actual use, the other end of the second arm 3 can pull the tool magazine tension spring 83 to replace manual operation.

[0040] For example, when the tool magazine tension spring 83 needs to be installed on the machine tool, one end of the tool magazine tension spring 83 is hooked on the back of the cutter disc 81. The second hook structure 31 of the second arm 3 is hooked to the other end of the tool magazine tension spring 83, and then the first arm 2 is pressed downward, that is, the first arm 2 rotates around the axis of the shaft seat 1. The downward pressure of the first arm 2 will pull the second arm 3 to the side away from the tool magazine tension spring 83, thereby pulling the tool magazine tension spring 83 until the end of the tool magazine tension spring 83 is hooked on the tool magazine bracket 82 (in the prior art, the inner side of the tool magazine bracket 82 is generally provided with a raised cylindrical structure for hooking the tool magazine tension spring 83), thereby realizing that one end of the tool magazine tension spring 83 is connected to the cutter disc 81, and the other end of the tool magazine tension spring 83 is connected to the tool magazine bracket 82. Adopting the installation jig in the embodiment of the present invention to replace manual operation to install the tool magazine tension spring can improve work efficiency and convenience, and is applicable to machine tools or tool magazine tension springs 83 of different specifications.

[0041] In some embodiments, reference Figure 1 and Figure 2 The shaft seat 1 has an opening, flanked by a first side plate 11 and a second side plate 12. The mounting fixture also includes a rotating shaft 4, which can be a cylindrical pin. One end of the first arm 2 is inserted into the opening, and the rotating shaft 4 passes through the first side plate 11, the first arm 2, and the second side plate 12 in sequence.

[0042] When the first arm 2 is rotated, the first arm 2 rotates around the rotation axis 4. Inserting one end of the first arm 2 into the opening forms a hidden structure arrangement, avoiding the problem of the first arm 2 being installed outside the shaft seat 1 and possibly interfering with other structures.

[0043] In some embodiments, reference Figure 1 and Figure 2 The positioning holes include a first positioning hole 13 and a second positioning hole 14, each corresponding to the first positioning hole 13. Multiple first positioning holes 13 are arranged in a circular arc on the first side plate 11, while multiple second positioning holes 14 are arranged in a circular arc on the second side plate 12. Specifically, the multiple first positioning holes 13 are arranged in a semicircular shape, and the multiple second positioning holes 14 are also arranged in a semicircular shape. The first positioning pin 5 is used to sequentially pass through the first positioning hole 13 and the second positioning hole 14 to prevent the first arm 2 from further rotation.

[0044] Specifically, the first side plate 11 is provided with a plurality of first positioning holes 13 extending therethrough, and the second side plate 12 is provided with a plurality of second positioning holes 14 extending therethrough, with the first positioning holes 13 and the second positioning holes 14 being provided in a one-to-one correspondence. A first positioning pin 5 passes through both the first and second positioning holes 13, 14. The first positioning pin 5 blocks the rotation of the first arm 2, preventing it from further rotating and thus preventing it from falling. Once the first arm 2 has been positioned about the axle seat 1, the first positioning pin 5 is then passed through the first and second positioning holes 13, 14, sequentially to limit the position of the first arm 2.

[0045] In some embodiments, reference Figure 1 and Figure 2 The second arm 3 includes a first screw 33, a sleeve 35, and a second screw 34, which are connected in sequence. The first screw 33 and sleeve 35 are threadedly connected, and the second screw 34 and sleeve 35 are also threadedly connected. One end of the first screw 33 is connected to the first arm 2. A second hook structure 31 is provided on the first screw 33. A third hook structure 32 is provided near the end of the second arm 3 away from the second hook structure 31.

[0046] Specifically, the third hook structure 32 is mounted on the second screw 34. Both the first screw 33 and the second screw 34 are threadedly connected to the sleeve 35. Rotating the first screw 33 or the second screw 34 adjusts the length of the second arm 3. For example, relative rotation of the first screw 33 and the sleeve 35 increases or decreases the length of the portion of the first screw 33 located within the sleeve 35, thereby adjusting the length of the first screw 33 located outside the sleeve 35 and, consequently, adjusting the length of the second arm 3. Rotating the second screw 34 similarly adjusts the length of the second arm 3.

[0047] In some embodiments, reference Figure 1 and Figure 2 The second arm 3 also includes a first nut 36 and a second nut 37. The first nut 36 is mounted on the connection between the first screw 33 and the sleeve 35 to secure the first screw 33 and the sleeve 35. The second nut 37 is mounted on the connection between the second screw 34 and the sleeve 35 to secure the second screw 34 and the sleeve 35. To adjust the length of the second arm 3, the length of the first screw 36 or the second screw 37 inserted into the sleeve 35 can be increased or decreased, and the first nut 36 or the second nut 37 is used to secure the second arm 3. The arrangement of the first nut 36 and the second nut 37 allows the second arm 3 to withstand greater tension while preventing the first screw 36 and the second screw 37 from easily extending or contracting.

[0048] In some embodiments, reference Figure 1 and Figure 2The mounting fixture further includes a second positioning pin 6, which is used to be inserted into any positioning hole. When the second positioning pin 6 is inserted into the positioning hole, the second positioning pin 6 is located on the rotation path of the first arm 2 to prevent the first arm 2 from continuing to rotate in the second direction, which is the opposite direction of the first direction. In this embodiment, reference Figure 2 , the first direction may be clockwise. Correspondingly, the second direction is counterclockwise.

[0049] Specifically, the second positioning pin 6 is located on a side of the first arm 2 relatively close to the second arm 3 to prevent the first arm 2 from rotating counterclockwise. Figure 2 As shown, the second positioning pin 6 is located on the left side of the first arm 2 (with Figure 2 When the second arm 3 pulls the tool magazine tension spring 83, the second arm 3 will be subjected to a reaction force. The second positioning pin 6 can resist the rotation tendency of the second arm 3 in the other direction.

[0050] In some embodiments, reference Figure 1 and Figure 2 A third hook structure 32 is provided at one end of the second arm 3 away from the second hook structure 31; one of the first hook structure 21 and the second hook structure 31 is a ring structure and the other is a hook structure, while the third hook structure 32 is a hook structure or a ring structure. The third hook structure 32 is provided so that this end of the second arm 3 can be connected to an external component (for example, a tool magazine tension spring 83). The third hook structure 32 is a hook structure, which facilitates the connection and disassembly of the second arm 3 and an external component (for example, a tool magazine tension spring 83). The first hook structure 21 and the second hook structure 31 are connected by hooking the hook structure on the ring structure. When the two need to be disassembled, the second hook structure 31 can be removed from the first hook structure 21, which facilitates the installation and disassembly operations.

[0051] In some embodiments, reference Figure 1 and Figure 2 At least two first hook structures 21 are provided along the length of the first arm 2. In practice, different machine tools may have different tool magazine tension springs 83 models or specifications, or different machine tool models may result in different distances between the tool disc 81 and the tool magazine support 82. To accommodate different machine tools, multiple first hook structures 21 are provided on the first arm 2.

[0052] In some embodiments, see Figure 1 as well as Figure 2 The mounting fixture further comprises a base plate 7, and the shaft seat 1 is arranged on the base plate 7. The base plate 7 is provided so that the entire mounting fixture is conveniently installed in an application environment such as a machine tool body.

[0053] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 as well as Figure 5 The second embodiment of the present invention provides a machine tool. The machine tool includes a machine tool body 8 and a mounting fixture in any one of the above embodiments. The machine tool body 8 includes a tool disc 81, a tool magazine support 82 and a tool magazine tension spring 83. The tool disc 81 is set on the tool magazine support 82, and the mounting fixture is installed on the tool magazine support 82. A fixing column 84 is set on the inner side of the tool magazine support 82. Please refer to Figure 5 One end of the tool magazine spring 83 is connected to the cutter disc 81, and the other end of the tool magazine spring 83 is connected to the end of the second arm 3 away from the first arm 2. The end of the tool magazine spring 83 away from the cutter disc 81 is finally pulled and hung on the fixed column 84 through the second arm 3.

[0054] In actual use, the mounting fixture in the embodiment of the present invention is installed on the tool magazine bracket 82 through the base plate 7. When the tool magazine tension spring 83 needs to be installed between the tool disc 81 and the tool magazine bracket 82, one end of the tool magazine tension spring 83 is hooked on the tool disc 81, and the other end of the tool magazine tension spring 83 is hooked on the second arm 3. Press the end of the first arm 2 away from the shaft seat 1, so that the first arm 2 rotates clockwise relative to the shaft seat 1, thereby pulling the second arm 3. The second arm 3 pulls the tool magazine tension spring 83 until the tool magazine tension spring 83 is hooked on the fixed column 84 of the tool magazine bracket 82. This method replaces the method of completely manually installing the tool magazine tension spring 83, can improve work efficiency and convenience, and is suitable for machine tools or tool magazine tension springs of different specifications.

[0055] Further, in some embodiments, please refer to Figure 3 The machine tool body also includes a column, and the mounting fixture can be located on the side of the column. For example, Figure 3 The mounting fixture may be located on a side of the column away from the tool magazine.

[0056] Furthermore, in some embodiments, a mounting position (not shown) for placing a mounting fixture is provided on the tool magazine support 82.
