Description

Technical Field

[0001] This utility model relates to the field of vertical machining technology, and more particularly to a vertical machining center fixture. Background Technology

[0002] With the continuous development of modern manufacturing, higher and higher requirements are being placed on the precision, efficiency and flexibility of machining. Vertical machining centers, as a commonly used machining equipment, are widely used in the field of mechanical manufacturing. However, to give full play to the performance of vertical machining centers and complete the machining of various complex parts efficiently and accurately, suitable fixtures are indispensable. Traditional vertical machining center fixtures can meet the machining needs to a certain extent, but they also have some limitations. The positioning accuracy of some general fixtures is limited, making it difficult to meet the machining requirements of high-precision parts. The clamping method of some fixtures is complicated and the operation is cumbersome, resulting in low machining efficiency.

[0003] Existing technologies are capable of precisely positioning and clamping workpieces of conventional shapes, including cubes and flat plates, meeting various processing tasks with general precision requirements. As a result, these technologies are widely used in multiple fields of mechanical manufacturing and parts processing, effectively improving production efficiency and processing quality.

[0004] However, the structure is relatively simple and the function is limited, making it difficult to adapt to the diverse processing needs of workpieces of different shapes and sizes. When processing irregularly shaped workpieces, it often cannot provide stable and precise clamping, causing the workpiece to shift or shake during processing, which seriously affects the processing accuracy and surface quality. At the same time, some fixtures cannot achieve firm fixation when clamping workpieces of specific shapes or spherical parts, which easily causes the parts to move during processing, which not only reduces the processing quality of the parts, but also causes damage to the parts and increases production costs.

The bottom of the sliding post 2071 is slidably connected to a groove 2072.

[0032] Specifically, the linkage assembly 203 includes a component called slider 2031, which is tightly fixed to the outer wall of the bidirectional threaded column 202 at its central position via a threaded connection, ensuring a stable connection and smooth relative movement between the two. Connecting rods 2032 are fixedly connected to the left and right sides of slider 2031, respectively. These connecting rods 2032 transmit force and motion, enabling the entire linkage assembly 203 to work in a coordinated manner. The fixing assembly 206 mainly consists of slide rod 2061, the outer wall of which is fixedly installed at the central position of slider 205, ensuring the stability and reliability of slide rod 2061 within slider 205. Fixed blocks 2062 are fixedly connected to both the front and rear sides of slide rod 2061. These fixed blocks 2062 further enhance the stability and support of slide rod 2061, ensuring that the entire fixed assembly 206 remains stable during movement. The limiting assembly 207 includes a component called sliding column 2071. The top of sliding column 2071 is fixedly connected to the bottom of inverted L-shaped plate 4, ensuring the vertical stability of sliding column 2071.

The middle of the outer wall of the first bidirectional threaded column 202 is fixedly connected to a blocking column 5. The top of the load-bearing plate 1 is provided with multiple rectangular openings 6.

[0034] Specifically, the sliding component 211 is composed of a second sliding rod 2111.

The blocking cylinder 5 is used to limit and guide the rotation of the bidirectional threaded column 202, ensuring the movement accuracy and stability of the threaded column. Multiple rectangular openings 6 are evenly opened on the top surface of the load-bearing plate 1. These rectangular openings 6 not only help to reduce the overall weight of the load-bearing plate 1, but also facilitate the installation and fixing of other components, improving the practicality and flexibility of the entire structure.

[0035] Working principle: Before processing, the workpiece needs to be fixed and clamped. The workpiece is placed on the top of the load-bearing plate 1. By controlling the turntable 204, the bidirectional threaded column 202 rotates, causing the front and rear sliders 2031 to move back and forth, which in turn drives the left and right sliders 205 to move. This causes the top inverted L-shaped plate 4 to gradually move towards the center. After reaching an appropriate distance, the motor 208 is started, causing the bidirectional threaded column 209 to rotate, which causes the top L-shaped clamp 308 to converge towards the center. The front has a sliding rod 2111 for the slider 2112 to slide on the outer wall, making the structure stable and preventing it from falling. The convergence towards the center tightly clamps the workpiece, making it convenient for workers to carry out the next processing step. The operation is simple and the clamping is stable, meeting the needs of users.

[0036] When the workpiece has a complex shape and requires different clamps for fixing, simply loosen the knob 306 at the bottom of the fixing plate 301, then press the pressing frame 3051 and pull the L-shaped clamp 308 outwards, so that the fixing post 307 of the fixed connection is pulled out from the circular hole 304 in the fixing plate 301. Then the spring 3052 will push the pressing frame 3051 up. When reinstalling, simply reverse the operation process. This disassembly structure allows for fast clamp replacement and makes it easy for users to operate.

[0037] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
