Description

Technical Field

[0001] The utility model belongs to the technical field of chucks, and in particular relates to a novel barrel-type chuck structure. Background Art

[0002] As an important clamping device, barrel chuck plays a vital role in industrial production. It is usually used in the field of mechanical processing to clamp workpieces of various shapes and sizes, such as round rods, square tubes, rectangular tubes, etc., so as to perform turning, milling, drilling and other processing operations. The traditional barrel chuck structure usually adopts a four-sided clamping mechanism for synchronous clamping. This clamping method can only clamp some relatively standard symmetrical workpieces, and cannot effectively clamp square tubes and some special-shaped workpieces. Utility Model Content

[0003] The purpose of this utility model is to solve some limitations of the traditional barrel-type chuck structure. For example, when clamping workpieces of different shapes and sizes, chucks of different specifications need to be replaced, which increases production costs and operation complexity. In addition, for workpieces of special shapes, the clamping effect of the traditional chuck structure may not be good and cannot meet the needs of high-precision processing.

[0004] The utility model achieves the above-mentioned purpose through the following technical scheme: a new type of barrel-type chuck structure, including a large clamping tooth, a group of propulsion clamping components are arranged on the upper end of the large clamping tooth, two groups of propulsion clamping components are arranged on the upper end of the group of propulsion clamping components, and clamping discs are arranged on the upper ends of the two groups of propulsion clamping components;

[0005] The set of propulsion and clamping components includes a fixed seat, the lower end of the fixed seat is fixedly connected to two first telescopic cylinders, the output end of the first telescopic cylinder passes through the upper end of the fixed seat and is fixedly connected to a first propulsion disk, guide columns are arranged at the four corners of the first propulsion disk, two connecting columns are symmetrically arranged on both sides of the upper end of the first propulsion disk, the connecting columns are fixedly connected to a first pushing connecting rod, and the upper end of the first pushing connecting rod is fixedly connected to a first sliding clamp. Through the arrangement of one set of propulsion and clamping components and two sets of propulsion and clamping components, two sets of clamping methods are realized, and separate clamping is completed in the horizontal and vertical directions, so that different sizes can be completed, whether it is round rods or square tubes and rectangular tubes, and can meet the clamping requirements.

[0006] Furthermore, the two groups of propulsion and clamping assemblies include two second telescopic cylinders, the output ends of the second telescopic cylinders pass through the upper end of the fixed seat and are fixedly connected to a second propulsion disk, two second propulsion connecting rods are symmetrically arranged on both sides of the upper end of the second propulsion disk, through holes are symmetrically arranged on both sides of the second propulsion disk, and the upper ends of the second push connecting rods are fixedly connected to second sliding clamps. The design of the second group of propulsion and clamping assemblies enhances the versatility of the chuck, making it applicable to a wider range of workpiece types and processing scenarios.

[0007] Furthermore, the connecting column is arranged through the through hole, and the first group of propulsion components and the second group of propulsion components are arranged up and down, and are clamped separately, which is more flexible.

[0008] Furthermore, the upper end of the clamping plate is provided with four symmetrical sliding grooves for assembly and connection with the first sliding clamp and the second sliding clamp.

[0009] Compared with the prior art, the beneficial effects of this invention are:

[0010] 1. Diversified clamping methods: The structure includes one and two groups of push clamping components. Through their settings, two groups of clamping methods are realized. These two clamping methods can be clamped separately horizontally and vertically to meet the clamping needs of workpieces of different sizes and shapes, such as round rods, square tubes, rectangular tubes, etc., which improves the flexibility and applicability of clamping;

[0011] 2. Enhanced chuck versatility: The introduction of the second set of push-on clamping component design enhances the versatility of the chuck, making the chuck structure applicable to a wider range of workpiece types and processing scenarios;

[0012] 3. Flexibility and adjustability: The four symmetrical slides on the upper end of the clamping plate are assembled and connected with the first sliding clamp and the second sliding clamp, which further enhances the stability and accuracy of clamping, and also provides a more convenient adjustment and operation method; BRIEF DESCRIPTION OF THE DRAWINGS
