Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bellows production, and in particular relates to a special notching fixture for double-interface bellows. Background Art
[0002] When the bellows are hydraulically formed, process waste edges are reserved, and a cutting process is set up in the subsequent process to provide customers with customized interface shapes and sizes. Usually, the bellows has an interface at one end and a closed bottom at the other end. When cutting the bellows, only one cut is needed to meet the requirements. However, some customers also customize the bellows with interfaces at both ends, which require two cuts and the lengths of the two ends must be kept consistent, with a parallelism within 0.1mm.
[0003] The previous cutting clamping method is to clamp the process end of the bellows, relying on the end face of the spring collet and the process corrugated surface for positioning. Due to the limitations of the bellows process, the interface length after the bellows is cut has a certain height difference, which is easy to cause tolerance accumulation on the double-interface bellows, making the parallelism of the interface end face of the bellows not meet the standard. Utility Model Content
[0004] In order to solve the problems raised in the above background technology, the utility model provides a special notching fixture for a double-interface corrugated pipe, which has the characteristics of simple structure and good parallelism.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special cutting clamp for double-interface corrugated pipes, including a spring clamp, a clamp ring is provided inside the spring clamp, and the clamp ring includes a symmetrically arranged left clamp block and a right clamp block, wherein the left clamp block and the right clamp block are both provided with clamp grooves inside.
[0006] In order to ensure the coaxiality of the double-interface bellows and the spring chuck after clamping, positioning grooves are further provided on both ends of the left clamping block and the right clamping block respectively.
[0007] In order to prevent the double-interface bellows from being crushed, the friction force can also be increased to prevent the double-interface bellows and the clamp ring from rotating relative to each other during cutting. Furthermore, a rubber pad is provided inside the clamping groove.
[0008] In order to ensure the parallelism of the left clamping block and the right clamping block, further, a protrusion is provided on the end surface of the left clamping block in contact with the right clamping block, and a groove corresponding to the protrusion is provided on the right clamping block.
[0009] In order to position the installation of the clamp ring, a positioning hole is further provided inside the spring clamp.
[0010] In order to limit the installation of the clamp ring and ensure the consistency of the clamping position of the clamp ring each time, a step is further provided at the lower end of the positioning hole.

[0012] 1. The utility model sets a clamp ring inside the spring chuck, and the clamp ring includes a symmetrically arranged left clamp block and a right clamp block. The double-interface bellows is clamped by the left clamp block and the right clamp block, and then put into the spring chuck, and the interface at one end of the double-interface bellows is cut off first, and then the clamp ring is taken out and turned around, and then the interface at the other end is cut off, so as to ensure the consistency and parallelism of the interface lengths at both ends of the double-interface bellows;
[0013] 2. After the left clamping block and the right clamping block of the utility model are clamped with the double-interface bellows, the positioning groove fits with the outer diameter of the interface of the double-interface bellows, thereby ensuring the coaxiality of the double-interface bellows and the spring chuck after clamping;
[0014] 3. The end surfaces of the left clamping block and the right clamping block of the utility model are provided with a protrusion, and the right clamping block is provided with a groove corresponding to the protrusion to ensure the parallelism of the left clamping block and the right clamping block;
