Description

Technical Field

[0001] This utility model relates to the field of ceramic processing, and in particular to a cylindrical axial feature fixture. Background Technology

[0002] For cylindrical products with other structural features on both ends, traditional CNC machine tools require two clamping operations, one for each end feature. This machining method is often inefficient for such cylindrical products, requiring operators to perform two clamping operations and the machine tool to perform two centering operations, consuming significant time and effort from the operators.

[0003] The State Intellectual Property Office application number 202220413838.3 discloses a symmetrical wire cutting fixture for cylindrical workpieces, including a base. A V-shaped groove is formed on the top of the base, and a cylinder is placed on top of the V-shaped groove. Sliding cavities are formed at both ends of the top of the base. A first locking tooth is fixedly installed on the top of the inner side of each sliding cavity. A limiting plate is provided on the inner side of each sliding cavity, and a first threaded rod is threadedly connected to the internal side of the limiting plate. Moving blocks are provided at both ends of the top of the base, and a support plate is fixedly installed on the top of each moving block. This utility model utilizes the method of placing the cylinder on the V-shaped groove, then rotating the first threaded rod to release the first locking tooth from the second locking tooth, causing a baffle to hold the cylinder in the middle, and then rotating the second threaded rod to fix the cylinder. This greatly reduces the time the worker spends clamping the cylinder, increases efficiency, and provides more stable clamping. However, this application has a complex structure, requiring two clamping operations to process both end faces. Utility Model Content

[0021] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0022] Example 1: Figure 1-3 As shown: In order to facilitate the processing of cylindrical products with characteristic structures at both ends and improve production efficiency, this utility model discloses a cylindrical axial feature fixture, including a clamping support column 1, a positioning clamping block 2, and a spring buckle 3.

[0023] The clamping support column 1 is made of stainless steel and its dimensions are designed and processed according to the stroke of the CNC engraving machine and the size of the product. It includes 9 square slots 11 and 2 base plate features, and the bottom surface has good flatness (flatness is about 0.05, and the clamping accuracy is high). After the machine tool platform is powered on, the clamping support column 1 can be reliably fixed by magnetic force. By flipping it up and down, the processing of both ends of the product can be convenient.

[0024] The positioning clamping block 2 is made of rubber material and consists of clamping features and slot fixing features. It can cooperate with the clamping support column 1 to control the clamping position of cylindrical products of different sizes. In the figure, the positioning clamping block is an angular clamping component, and the angles of the left and right angular clamping components are opposite each other.

[0025] The spring buckle 3 is made of spring material and its two ends are fixed to the two positioning clamping blocks 2 respectively. It works together with the positioning clamping blocks 2 to achieve the firmness of product clamping. The spring buckle 3 can be a common part on the market, or it can be composed of a high-strength tension spring 32. The two ends of the high-strength tension spring 32 are fixed to the fixing posts 31 extending outward from the surface of the positioning clamping blocks.

[0026] A novel cylindrical axial feature fixture with a unique structure solves the inconvenience of multiple clamping operations for machining the two end faces of traditional cylindrical feature products, thereby improving production efficiency.

[0027] Please see Figure 1 This utility model discloses a cylindrical axial feature clamp, which includes a clamping support column 1, a positioning clamping block 2, a spring buckle 3, and a product 4.

[0028] The position is adjusted according to the size of product 4. The positioning clamping block 2 and the spring buckle 3 work together to achieve the first-level clamping effect of product 4 through the spring force. The rubber positioning clamping block 2 and the clamping support column 1 work together to achieve the second-level clamping effect between the support column and product 4 through the through hole positioning slot structure. The stainless steel clamping support column 1 and the CNC machine tool platform work together. After the platform is electromagnetized, it can attract the stainless steel clamping support column 1 to achieve the third-level clamping effect of the machine tool platform on product 4.

[0029] In this embodiment, the positioning clamping block 2 and the spring buckle 3 are first applied together to the product 4 to achieve a first-level clamping effect on the product.

[0030] The square column structure of the positioning clamping block 2 is placed in the slot 11 corresponding to the clamping support column 1 to achieve a two-stage clamping effect on the product 4.

[0031] When the machine tool platform is powered by an electromagnetic force, it attracts the stainless steel clamping support column 1, thereby achieving three-level clamping of product 4 and making it secure. When processing the other end of the cylindrical product, it is only necessary to de-energize and flip the product in the second-level clamping state, and then apply electromagnetic force to clamp and process product 4.

[0032] When working, process the materials according to the following steps:

[0033] 1. Material clamping: Fix the cylindrical product onto the clamping fixture according to the steps above;

[0034] 2. Measurement Center: Use a dial indicator to measure the product center and processing location;

[0035] 3. Tool setting: Move the grinding wheel to the inner diameter of the material, manually rotate the grinding wheel, and move the grinding wheel to the closest point to the inner diameter. Move and rotate the grinding wheel at the same time until the tool touches the inner diameter of the material, then retract 0.5mm. This is the zero point of machining.

[0036] 4. Machining: Start the machine tool according to the set machining parameters. After the program is completed, turn off the machine tool table current, flip the clamping device up and down, and turn on the power again to process the other end surface feature.

[0037] 5. Fixture maintenance: If the product is found to be flat, check the fixture dimensions and surface condition in a timely manner.

[0038] This invention solves the problem of low clamping efficiency in traditional processing methods for cylindrical products by designing a universal clamping fixture for cylindrical products. It significantly improves the clamping efficiency of operators and also enhances the precision and quality of the products.

[0039] This utility model provides a cylindrical axial feature fixture, which enables the machining of both end face features of cylindrical feature products in a single clamping and centering operation, facilitating the work of machining personnel and improving machining efficiency.
