[0005] The purpose of this invention is to address the aforementioned problems in the prior art by providing a gear-shaping clamp.

[0006] The objective of this utility model can be achieved through the following technical solution: A gear-shaping clamp includes a main housing, a positioning ring, a mounting housing, an elastic chuck, a clamping rod, a spacer, and a limiting ring. The main housing is a hollow cylindrical shape with connecting rings formed at both ends. Several first limiting holes are provided in the connecting rings. First connecting steps and second connecting steps are respectively provided on both sides of the main housing. A mounting protrusion is formed on one side of the main housing of the first connecting step. The positioning ring is sleeved on the outside of the mounting protrusion.

The elastic clamp has several third limiting holes. A connecting recess is provided on one side of the spacer. A spacer inside the connecting recess has several fourth limiting holes. The second connecting step extends into the connecting recess to connect the main housing and the spacer. The limiting ring body is connected to the other end of the spacer and has several fifth limiting holes. The clamping rod passes through the fifth limiting hole, the fourth limiting hole, the first limiting hole, the second limiting hole, and the third limiting hole in sequence and is connected to the elastic clamp.

[0007] In the aforementioned tooth-shaping fixture, a fixed end cap is fixedly connected to one end of the mounting housing.

[0008] In the aforementioned tooth-shaping clamp, the elastic chuck is an overall coaxial stepped annular structure, and the elastic chuck includes an elastic clamping section and a connecting positioning section, with a buffer groove formed between the elastic clamping section and the connecting positioning section.

[0009] In the aforementioned tooth-shaping fixture, the limiting ring body has an internal mounting groove, in which a connecting bolt is installed. The connecting bolt passes through the opening at the center of the limiting ring body and extends out of the limiting ring body.

[0010] In the aforementioned tooth-shaping fixture, a plurality of connecting holes are provided on one side of the positioning ring body, and the positioning ring body is fixedly connected to the mounting housing through the connecting holes.

[0011] Compared with the prior art, the toothed clamp provided by this utility model has the following beneficial effects: 1. The main housing, through the connecting ring of the first connecting step and the mounting housing, and the connecting recess of the second connecting step and the spacer, and with the help of the limiting hole and the clamping rod, quickly achieves precise docking of multiple parts; the positioning ring is fitted with the mounting protrusion, and the limiting ring is connected to the spacer, etc., which simplifies the assembly relationship, reduces the installation difficulty, and reduces the assembly time; 2. Each part forms a stable connection and positioning system through the clamping rod passing through the limiting hole. The stepped connection structure of the main housing, the mounting housing, the spacer, etc., enhances the overall structural rigidity of the clamp; 3. The elastic clamp adopts a coaxial stepped ring structure, with an elastic clamping section, a connecting positioning section, and a buffer groove between them. When the elastic clamp is subjected to external force, the buffer groove can effectively disperse the stress, provide sufficient space for elastic deformation, avoid stress concentration leading to clamp damage, and significantly improve the buffering effect.

Detailed Implementation

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figures 1 to 3As shown, this embodiment includes a main housing 1, a positioning ring 2, a mounting housing 3, an elastic clamp 4, a clamping rod 5, a spacer 6, and a limiting ring 7. The main housing 1 is a hollow cylindrical shape with connecting rings 11 integrally formed at both ends. The connecting rings 11 are evenly provided with several first limiting holes 15 around their circumference, providing a positioning basis for the clamping rod 5 to pass through. The main housing 1 has a first connecting step 12 and a second connecting step 13 machined on both sides. On the outer wall of the main housing 1 on one side of the first connecting step 12, a mounting protrusion 14 is integrally formed. The positioning ring 2 is adapted to be installed outside the mounting protrusion 14, and preliminary positioning is achieved through structural adaptation. The mounting housing 3 has a connecting ring 31 integrally formed at one end. The connecting ring 31 has several second limiting holes 32 inside. During assembly, the first connecting step 12 of the main housing 1 extends into the connecting ring 31, so that the main housing 1 and the mounting housing 3 achieve coaxial docking through the stepped surface, providing a coaxial reference for the subsequent insertion of the clamping rod 5.

[0018] like Figures 1 to 2 As shown, a connecting recess 61 is machined on one side of the spacer 6. Several fourth limiting holes 62 are correspondingly opened on the spacer 6 inside the connecting recess 61. The second connecting step 13 of the main housing 1 extends into the connecting recess 61, so that the main housing 1 and the spacer 6 are coaxially connected through the stepped surface fit, ensuring the overall coaxiality accuracy of the fixture. The limiting ring 7 is connected to the other end of the spacer 6 by bolts or interference fit. Several fifth limiting holes 71 are opened on the limiting ring 7, and an installation groove 72 is machined inside it. A connecting bolt 9 is adapted to be installed in the installation groove 72. The connecting bolt 9 passes through the opening at the center of the limiting ring 7 and extends out of the limiting ring 7 for docking and fixing with external equipment, realizing the overall installation and positioning of this embodiment.

[0019] To elaborate further, such as Figures 2 to 3 As shown, the elastic chuck 4 adopts a coaxial stepped annular structure and is fixedly installed inside the mounting housing 3. Several third limiting holes 41 are opened in its circumference for cooperating with the clamping rod 5. The elastic chuck 4 includes an elastic clamping section 42 and a connecting positioning section 43. The elastic clamping section 42 is used to directly contact and clamp the workpiece. The connecting positioning section 43 is adapted to the internal structure of the mounting housing 3 for positioning. A buffer groove 44 is opened between the elastic clamping section 42 and the connecting positioning section 43. The buffer groove 44 can provide elastic deformation space when the elastic chuck 4 is subjected to external force, avoid stress concentration, and improve the buffering effect and service life of the chuck.

[0020] like Figures 1 to 2As shown, the clamping rod 5 passes through the fifth limiting hole 71 of the limiting ring 7, the fourth limiting hole 62 of the spacer 6, the first limiting hole 15 of the connecting ring 11 of the main housing 1, and the second limiting hole 32 of the connecting ring 31 of the mounting housing 3 in sequence, and finally connects with the third limiting hole 41 of the elastic chuck 4. Through the axial movement of the clamping rod 5, the elastic clamping section 42 of the elastic chuck 4 is driven to contract or open, so as to realize the clamping and releasing action of the workpiece.

[0021] To elaborate further, such as Figures 1 to 2 As shown, a fixed end cap 8 is fixedly connected to one end of the mounting housing 3 by means of welding, bolting, etc., which is used to close the end of the mounting housing 3 and to protect and limit the internal components such as the elastic clamp 4.

[0022] To elaborate further, such as Figures 1 to 2 As shown, a number of connection holes 21 are provided on one side of the positioning ring 2. By passing bolts through the connection holes 21, the connection between the mounting housing 3 and the positioning ring 2 is further strengthened, thereby improving the overall structural stability of this embodiment.
