DETAILED DESCRIPTION

[0023] The present invention will be described in detail below with reference to the accompanying drawings.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] A brace clamp, such as Figure 1-3 As shown, it includes a base plate 1, and an axis positioning assembly 2 is provided in the middle of the front side of the base plate 1, and the axis positioning assembly 2 includes a first V-shaped block 21 fixedly arranged on the front side of the base plate 1, and the opening of the first V-shaped block 21 faces forward; a second V-shaped block 22 is provided in front of the first V-shaped block 21, and the opening of the second V-shaped block 22 faces backward, and the second V-shaped block 22 is connected to the base plate 1 through a clamping assembly; there is also a circumferential limiting assembly 3 on the base plate 1, and the circumferential limiting assembly 3 is provided on the left side and / or right side of the axis positioning assembly 2, and the circumferential limiting assembly 3 includes a limiting member arranged forward from the base plate 1, and a limiting plane is provided at the front end of the limiting member.

[0026] Specifically, the base plate 1 serves as the basis of the fixture, providing a stable support surface for fixing the fixture to the machine tool workbench or other fixed surface. The axis positioning device V-block is used to clamp the cylindrical part of the strut, provide axial positioning, and ensure the correct position of the strut in the fixture. The design of the V-block assembly can adapt to struts of different diameters and has a certain degree of versatility. The clamping assembly is used to fix the V-block assembly on the base plate 1, and the position of the V-block can be adjusted to adapt to struts of different sizes. The circumferential limit assembly 3 is located on the left and / or right side of the axis positioning assembly 2, and is used to limit the rotation of the strut in the horizontal direction (circumferential direction) to ensure the stability of the strut during processing. The limiter is set forward from the base plate 1, and its front end is provided with a limiting plane for contacting a specific part of the strut to prevent the strut from rotating during processing. The design of the limiting plane ensures that the strut does not move unnecessarily when subjected to processing force, while also avoiding damage to the surface of the strut.

[0027] In another specific embodiment, the limiting member is a limiting screw 31, the rear portion of which is screwed into the base plate 1. The limiting screw 31 has a helical thread and is screwed into a threaded hole in the base plate 1. The front end of the limiting screw 31 is typically a flat surface or a head with a boss. This head serves as the limiting surface, which contacts the strut to limit its circumferential movement.

[0028] As another specific embodiment, a positioning nut 32 is further provided at the rear of the limit screw 31. This nut 32 is used to secure the axial position of the limit screw 31, preventing it from loosening due to vibration or other external forces during use. Rotating the nut 32 precisely adjusts the length of the limit screw 31 within the base plate 1, thereby varying the distance between the head of the limit screw 31 and the strut, allowing for fine-tuning of the strut's positioning accuracy.

[0029] As another specific embodiment, the axis positioning components 2 include two, and the two axis positioning components 2 are arranged in parallel along the left and right sides. The two axis positioning components 2 are arranged in parallel along the left and right sides to ensure that the support rod remains balanced in the horizontal direction, increase the stability of the entire structure, and help prevent the support rod from shifting.

[0030] As another specific embodiment, two circumferential limiter assemblies 3 are provided on each side of the axis positioning assembly 2, and the two circumferential limiter assemblies 3 are arranged in parallel with each other. By providing two circumferential limiter assemblies 3 on each side of the axis positioning assembly 2, the horizontal rotation of the support rod can be more effectively restricted, thereby enhancing the stability of the support rod during processing.

[0031] As another specific embodiment, the clamping device includes a pressure plate 25, which acts backward on the second V-shaped block 22. The upper and lower ends of the pressure plate 25 are connected to the base plate 1 via support members 26. The pressure plate 25 compresses the second V-shaped block 22 backward, securing the workpiece in the V-shaped block and preventing it from moving during machining. The support members 26 connect the upper and lower ends of the pressure plate 25 and transmit force to the base plate 1, forming a stable structure for the entire clamping device.

[0032] As another specific embodiment, the middle portion of the pressure plate 25 is provided with at least one connecting groove or a plurality of connecting holes, and the support member 26 and / or the second V-block 22 are connected to the pressure plate 25 via the connecting groove or the connecting hole. The design of the connecting groove or the connecting hole allows the pressure plate 25 to be used in conjunction with a variety of different support members 26 or V-blocks, thereby enhancing the scope of application of the clamping device. The connecting hole can be used to pass through the support member 26 and / or the second V-block 22, while the connecting groove allows the support member 26 or the V-block to move within a certain range, facilitating assembly. Specifically, the connecting groove is a through groove that passes through the front and back. When a connecting groove is used, it is preferred that there is one connecting groove, and the support member 26 and / or the second V-block 22 are both assembled through the connecting groove.

[0033] As another specific embodiment, both ends of the support member 26 are provided with threaded portions respectively used to connect the pressure plate 25 and the base plate 1, and the threaded portion at the front end of the support member 26 passes through the connecting groove or the connecting hole and is screwed with a first connecting nut 27. Each end of the support member 26 has an external threaded portion, which is used to connect with the pressure plate 25 and the base plate 1. The external threaded portion cooperates with the first connecting nut 27 and the internal threaded hole on the base plate 1 to achieve a tightening effect. The support member 26 can fix the pressure plate 25 and the base plate 1 through a simple screwing action of the first connecting nut 27, without the need for a complicated assembly process, saving installation time. Specifically, the middle part of the support member 26 is a support portion, and the outer diameter of the support portion is larger than the connecting groove or the connecting hole, so that the pressure plate 25 can be supported by the support portion.

[0034] In another specific embodiment, a connecting screw 23 is provided on the front side of the second V-shaped block 22. The connecting screw 23 is screwed into the connecting slot or hole, and then engaged with a second connecting nut 24. The combination of the connecting screw 23 and the second connecting nut 24 provides a reliable fastening force, ensuring that the V-shaped block is firmly attached to the pressure plate 25 and prevents displacement during processing. In addition to this method, the second V-shaped block 22 can also be fixedly connected to the pressure plate 25, but it is relatively impossible to replace the second V-shaped block 22 to adapt to different types of braces.

[0035] As another specific embodiment, the base plate 1 is further provided with a tool setting block assembly 4. The tool setting block assembly 4 is used to determine the relative position between the tool and the workpiece, ensuring accuracy during the machining process. It can also quickly complete tool positioning, reducing manual adjustment time and improving production efficiency.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The present invention extends to any new features or any new combinations disclosed in this specification, and any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that detailed technical features not disclosed in this embodiment, such as specific structures and connection methods, can be obtained by those skilled in the art from existing technologies and relevant experience, and the present disclosed embodiments do not specifically limit this.
