Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, specifically a chuck fixture for joint processing. Background Technology

[0002] In the joint machining process, efficient and precise clamping is crucial for ensuring machining quality and efficiency. Traditional joint machining fixtures are typically designed for joints of specific shapes and sizes. For example, fixtures used for machining bends are difficult to adapt to tees and crosses, let alone ball joints. This necessitates frequent fixture changes when producing various types of joints, consuming significant time and labor costs, and requiring readjustment after each change, severely impacting production efficiency. Therefore, developing a new type of chuck fixture that is compatible with multiple joint types, enables multi-faceted machining in a single clamping operation, and eliminates the need for frequent fixture changes is of significant practical importance. Utility Model Content

[0003] The purpose of this utility model is to provide a chuck fixture for joint processing, so as to solve the problem of poor fixture versatility and the need to frequently change fixtures to process different types of joints in the prior art, so as to realize the clamping of multiple joints at one time and perform multi-face processing, thereby improving processing efficiency and accuracy and reducing production costs.

[0004] A chuck fixture for joint processing, comprising:

[0005] Two opposing square column support bodies are hydraulically driven to move relative to each other to clamp the joint blank. The joint blank is placed on top of the lower square column support body.

[0006] The grippers are used to limit the joint blank. They are integrally formed on the four corners of the clamping surface of the square column support body. They have a tapered boss structure that is wider at the bottom and narrower at the top. Each gripper has three inclined clamping surfaces on its inner side. Each clamping surface is inclined towards the edge of the square column support body to form a multi-directional limiting clamping of the joint blank.

[0007] A connector block, used to connect and fix the clamp and chuck, is located at the end of the square column support body;

[0008] A chuck is used to mount fixtures and drive them to rotate for machining; it is assembled on a machine tool.

[0009] As a preferred embodiment of this utility model, the chuck includes: a chuck connecting part and an integrally formed chuck clamping part; the chuck connecting part is used to connect with the machine tool; the right side of the chuck clamping part has a waist-shaped cavity, and the upper and lower end faces of the waist-shaped cavity have insertion slots, and the insertion block is assembled in the insertion slot for installing and fixing the fixture.

[0010] As a preferred embodiment of this utility model, a circular hole is provided in the middle of the clamping surface of the square column support body for clamping a spherical joint blank.

[0011] As a preferred embodiment of this utility model, the edge of the circular hole is formed into an arc-shaped surface, which can increase the contact area, thereby improving the clamping force and protecting the joint blank.

[0012] As a preferred embodiment of this utility model, the connection between the square column support body and the plug-in block is set as an inclined reinforcing surface to improve the strength of the clamp.

[0013] As a preferred embodiment of this utility model, the chuck has a circular through-slot in the middle, which reduces its weight.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects:

[0015] This fixture is compatible with various connector types, including bends, tees, crosses, and ball joints, eliminating the need to change fixtures when processing different connectors, greatly improving production convenience. For example, when multiple connectors need to be processed simultaneously in a production workshop, using this fixture reduces downtime caused by fixture changes, making the production process smoother. The unique jaw design and overall structure allow for multi-faceted processing of the connector blank after a single clamping. Taking a tee connector as an example, the multi-directional limiting of the jaws allows for processing of three connection ports without re-clamping, ensuring positional accuracy between the ports and improving processing efficiency and product quality. Compared to traditional fixtures, this invention reduces the cumbersome operation of changing fixtures, saving manpower and time costs. According to actual tests, using this fixture can increase production efficiency by 30%-50% when mass-producing different types of connectors, significantly improving the production efficiency of enterprises.
