Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1 to 12 As shown, this utility model embodiment provides a combined tooling, including a tooling base 2, a clamping member 3, and multiple replaceable positioning members. The tooling base 2 has at least a horizontally arranged machining surface 21, a first side positioning surface 22 perpendicularly distributed to the machining surface 21, and at least one mounting portion; the machining surface 21 is provided with at least one positioning groove, each positioning groove being adapted to at least one type of rotating part; the clamping member 3 has a second side positioning surface 31, the clamping member 3 is selectively installed in one of the positioning grooves, and the second side positioning surface 31 is arranged relatively parallel to the first side positioning surface 22, and the corresponding type of rotating part is placed on the machining surface 21 and its radial movement is restricted by the first side positioning surface 22 and the second side positioning surface 31.

[0021] Positioning elements are selectively installed on the mounting part, each positioning element being adapted to a slot 16 of at least one type of rotating part to restrict the circumferential rotation of the corresponding type of rotating part; wherein, the plurality of replaceable positioning elements include at least a first positioning element 41, a second positioning element 42, and a third positioning element 43; the first positioning element 41 has a first positioning state and a second positioning state: when the first positioning element 41 is installed on the mounting part in the first positioning state, it adapts to and positions a first type of rotating part 11; when the first positioning element 41 is installed in the second positioning state, it adapts to and positions a second type of rotating part 12; when the second positioning element 42 is installed on the mounting part, it adapts to and positions a third type of rotating part 13; when the third positioning element 43 is installed on the mounting part, it adapts to and positions a fourth type of rotating part 14.

[0022] In this combined tooling, the machined surface 21 of the tooling base 2 is provided with multiple positioning slots. The clamping member 3 can be selectively installed in different positioning slots to adapt to the radial dimensions of different types of rotating parts, and provides reference support through the first side positioning surface 22. The clamping member 3 is installed in the positioning slot, and its second side positioning surface 31 is parallel and opposite to the first side positioning surface 22, which together restricts the radial movement of the rotating part. The replaceable positioning members (first positioning member 41, second positioning member 42, and third positioning member 43) on the mounting part are adapted to the rotating part slot 16 to restrict the circumferential rotation of the rotating part. Among them, the first positioning member 41 adapts to two types of parts by switching the installation state (first positioning state or second positioning state), and the second positioning member 42 and the third positioning member are adapted to the third type of rotating part 13 and the fourth type of rotating part 14, respectively, so as to realize the adaptability of this combined tooling to multiple types of rotating parts.

[0023] In some practical applications, the assembly tooling also includes a first bolt 5, which is used to fix the rotating part located between the first side positioning surface 22 and the second side positioning surface 31; the first bolt 5 is installed in the following two ways: The first installation method of the first bolt 5 (not shown in the figure): The clamping member 3 is threadedly connected to the first bolt 5, and the tail end of the first bolt 5 presses against the first flat plane 17 of the rotating part located between the first side positioning surface 22 and the second side positioning surface 31, and makes the rotating part abut against the first side positioning surface 22.

[0024] The second installation method of the first bolt 5 (such as...) Figure 3 and Figure 4 As shown): The tooling base 2 is threaded with the first bolt 5. The tail end of the first bolt 5 presses against the first flat plane 17 of the rotating part located between the first side positioning surface 22 and the second side positioning surface 31, and makes the rotating part abut against the second side positioning surface 31.

[0025] In summary, both installation methods of the first bolt 5 involve the clamping member 3 being installed in the positioning groove, and the tail end of the first bolt 5, which is connected by threads, directly pressing the first flat plane 17 of the rotating part. The axial thrust of the bolt is used to fix and press the rotating part between the first side positioning surface 22 and the second side positioning surface 31. This not only restricts the axial movement of the rotating part to a certain extent, but also restricts the circumferential rotation of the rotating part under the action of the first flat plane 17, so as to facilitate the threaded assembly of the rotating part with other parts.

[0026] In some practical applications, the mounting section has two mounting slots, a first mounting slot 23 and a second mounting slot 24, which are located on the mounting base (e.g., Figure 2 The positioning slot has two, a first positioning slot 211 and a second positioning slot 212, arranged in parallel. When the clamping member 3 is installed in the first positioning slot 211 and the first positioning member 41 is installed in the first mounting slot 23, it adapts to and positions the first type of rotating body part 11 and the second type of rotating body part 12. When the clamping member 3 is installed in the second positioning slot 212 and the second positioning member 42 is installed in the second mounting slot 24, it adapts to and positions the third type of rotating body part 13. When the clamping member 3 is installed in the second positioning slot 212 and the third positioning member 43 is installed in the second mounting slot 24, it adapts to and positions the fourth type of rotating body part 14.

[0027] Specifically, the first positioning member 41 includes a first insert 411 and a second insert 412 connected to the first insert 411 and distributed perpendicularly thereto.

[0028] When the first positioning member 41 is installed in the first positioning state: refer to Figures 3 to 4 As shown, the first positioning member 41 is embedded in the first mounting groove 23, and the second insert 412 at least partially protrudes from the surface of the machining surface 21; the second insert 412 is at least partially inserted into the slot 16 of the first type rotary body part 11 to achieve circumferential positioning of the first type rotary body part 11. In actual use, the first type rotary body part 11 is configured as a 50mm diameter tool extension rod. After one of the 50mm diameter tool extension rods is fixed by the combined tooling, it can be used to connect with other tool accessories or parts.

[0029] When the first positioning member 41 is installed in the second positioning state: refer to Figures 5 to 6 As shown, the first positioning member 41 is embedded in the first mounting groove 23, and the second insert 412 is located at the end of the first insert 411 away from the machining surface 21; the outer peripheral wall of the second type rotary body part 12 has a first outer flange 121 coaxially arranged, and the slot 16 of the second type rotary body part 12 is located on the first outer flange 121; the first outer flange 121 is located beside the machining surface 21 and abuts against the tooling base 2 and the clamping member 3 to achieve axial positioning of the second type rotary body part 12, and the first insert 411 is at least partially inserted into the slot 16 of the second type rotary body part 12 to achieve circumferential positioning of the second type rotary body part 12. In actual use, the second type rotary body part 12 is configured with a 50mm diameter tapered shank, and the portion of the tapered shank between the first side positioning surface 22 and the second side positioning surface 31 is a columnar structure and is fixed therein. One of the 50mm diameter taper shanks, once secured by this tooling assembly, can be used to connect with other tooling accessories via threads or bolts.

[0030] Therefore, the first positioning groove 211 and the first mounting groove 23 are combined as follows: The clamping member 3 is installed in the first positioning groove 211, and the first positioning member 41 (including the mutually perpendicular first insert 411 and second insert 412, forming a T-shaped structure) is installed in the first mounting groove 23. By switching the installation state of the first positioning member 41 (second insert 412 facing up / down), it can be adapted to: First type of rotating body part 11 (50mm tool extension rod): The second insert 412 protrudes from the machining surface 21 and is inserted into the slot 16 of the first type of rotating body part 11 to achieve circumferential positioning; Second type of rotating part 12 (50mm taper shank): The second insert 412 is located at the end away from the machining surface 21, and the first insert 411 is inserted into the slot 16 of the first outer flange 121 of the taper shank. At the same time, the first outer flange 121 abuts against the base and the clamping member 3 to achieve axial positioning.

[0031] Specifically, refer to Figures 7 to 8As shown, the second positioning member 42 is embedded in the second mounting groove 24 and has a second protrusion 421 protruding from the surface of the machined surface 21. The second protrusion 421 is inserted into the slot 16 on the third type rotary body part 13 to achieve circumferential positioning of the third type rotary body part 13. In actual use, the third type rotary body part 13 is configured as an 80mm diameter tool extension rod. After one of the 80mm diameter tool extension rods is fixed by the combined tooling, it can be used to connect with other tool accessories or parts.

[0032] Specifically, refer to Figures 9 to 10 As shown, the third positioning member 43 is embedded in the second mounting groove 24 and has a third protrusion 431 that protrudes out of the second mounting groove 24 and is located on the side of the mounting base; the outer peripheral wall of the fourth type rotary body part 14 has a second outer flange 141 coaxially arranged, and the slot 16 of the fourth type rotary body part 14 is located on the second outer flange 141; the second outer flange 141 is located on the side of the machining surface 21 and abuts against the tooling base 2 and the clamping member 3 to achieve axial positioning of the fourth type rotary body part 14, and the third protrusion 431 is embedded in the slot 16 of the fourth type rotary body part 14 to achieve circumferential positioning of the fourth type rotary body part 14.

[0033] Therefore, the combination of the second positioning slot 212 and the second mounting slot 24 is as follows: The clamping member 3 is installed in the second positioning groove 212, and the second positioning member 42 or the third positioning member 43 is selectively installed in the second mounting groove 24. The third type of rotating part 13 (80mm tool extension rod): the second protrusion 421 of the second positioning part 42 protrudes from the machining surface 21 and is inserted into the slot 16 of the third type of rotating part 13. Fourth type of rotating part 14 (80mm tapered shank): The third protrusion 431 of the third positioning part 43 is located on the side of the base and is embedded in the slot 16 of the second outer flange 141 of the tapered shank. The second outer flange 141 abuts against the base and the clamping part 3 to achieve axial positioning.

[0034] In other practical applications, based on any of the above implementation methods: refer to Figures 11 to 12As shown, the tooling base 2 is also provided with a circular groove 25 for positioning the fifth type rotating body part 15, and at least one threaded hole 26 perpendicular to the axial direction of the circular groove 25 and communicating in the circular groove 25. A second bolt 6 is threadedly connected in the threaded hole 26. The second bolt 6 abuts against the second flat plane 151 on the fifth type rotating body part 15 to restrict its circumferential rotation.

[0035] In actual use, the fifth-type rotating part 15 is configured as a tool extension screw, which includes a cylindrical end and a threaded end. The cylindrical end of the tool extension screw is inserted into the circular groove 25, and the inner wall of the circular groove 25 restricts the radial movement of the fifth-type rotating part 15. A second bolt 6 is screwed into the threaded hole 26 perpendicular to the axial direction of the circular groove 25. The tail end of the second bolt 6 abuts against the second flat plane 151, restricting the circumferential rotation of the fifth-type rotating part 15. The threaded end is exposed above the machined surface 21 and is directly used for connection with other parts. Figure 11 As shown, the threaded end of the fifth type rotating part 15 below is threaded with a nut, and the upper end of the nut is also connected to another fifth type rotating part 15, thereby realizing the connection between the two fifth type rotating parts 15; in this embodiment, a circular groove 25 and a matching threaded hole 26 are set separately, forming a parallel structure with the original positioning groove and mounting groove, thereby improving the compatibility of the combined tooling.
