Description

Technical Field

[0001] This utility model relates to the field of turning mechanism technology, specifically to a dual-turret synchronous turning mechanism. Background Technology

[0002] In the field of modern machining, turning is a fundamental and important machining method, widely used in aerospace, automobile manufacturing, precision instruments and many other industries. With the continuous development of the manufacturing industry, higher and higher requirements are being placed on the machining accuracy, surface quality and production efficiency of workpieces.

[0003] Traditional single-turret turning machines have significant limitations when machining workpieces. Since only one tool can be used at a time, frequent tool changes for workpieces requiring multiple operations and tool combinations not only greatly increase machining auxiliary time and reduce production efficiency, but also make it difficult to machine multiple parts of a workpiece simultaneously. For example, when drilling holes and surface finishing are required, they usually have to be done separately. Generally, one end is drilled first, and then the surface is cut flat, which further prolongs the machining cycle and increases production costs. Utility Model Content

[0004] In view of the problems existing in the above-mentioned turning mechanisms, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a dual-turret synchronous turning mechanism, which solves the problem that single-turret turning machines cannot process multiple parts of a workpiece at the same time. For example, when it is necessary to open holes and finish the surface of a workpiece, they can usually only be done separately. Generally, one end is opened first, and then the surface is cut flat, which further prolongs the processing cycle and increases production costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

A square hole is formed between the two first cavities and the second cavity. The two first trapezoidal blocks are slidably disposed inside the corresponding square holes and are fixedly connected to the other end of the corresponding movable plates.

[0009] Preferably, the first adjusting mechanism includes a cylinder, a second trapezoidal block, and two T-shaped blocks. The cylinder is fixedly connected to one side of the support column, and the output end of the cylinder passes through one side of the support column and extends into the interior of the second cavity. The second trapezoidal block is fixedly connected to the output end of the cylinder, and the two T-shaped blocks are respectively fixedly connected to the two inclined surfaces of the second trapezoidal block.

[0010] Preferably, the second adjusting mechanism includes a motor, a lead screw, and a limiting rod.

[0014] 1. This utility model adjusts the lateral spacing of the two cutting tools via an electric slide rail, allowing the first and second cutting tools to simultaneously process different parts of the workpiece, such as opening holes at one end and surface finishing. This avoids the frequent tool changes and step-by-step processing required by traditional single-turret machine tools, significantly reducing auxiliary time, enabling simultaneous operation of multiple processes, shortening the processing cycle, and reducing production costs.

[0025] The electric slide rail 5 drives the slider 6 and the support column 7 to move laterally along the base 1, adjusting the lateral distance between the double cutters and the workpiece 4. By changing the first cutting cutter 8 of different specifications, it is convenient to open a circular groove of different sizes at one end of the workpiece 4. Subsequently, by adjusting the height of the second cutting cutter 10, it can be applied to workpieces 4 of different sizes, thereby enhancing the practicality of the device.

[0026] To fix the first cutting tool 8, such as Figure 2-3As shown, the fixing mechanism includes two movable plates 11, two insert blocks 12, and two first trapezoidal blocks 13. The two movable plates 11 are slidably disposed inside the corresponding first cavities. Through holes are formed between the two grooves and the first cavities. The two insert blocks 12 are slidably disposed inside the through holes and are fixedly connected to one side of the corresponding movable plates 11. Square holes are formed between the two first cavities and the second cavity. The two first trapezoidal blocks 13 are slidably disposed inside the corresponding square holes and are fixedly connected to the other end of the corresponding movable plates 11. The first adjusting mechanism includes a cylinder 14. The second trapezoidal block 15 and two T-shaped blocks 16 are fixedly connected to one side of the support column 7. The output end of the cylinder 14 passes through one side of the support column 7 and extends into the interior of the second cavity.

The T-shaped blocks 16 on both sides slide along the T-shaped groove of the first trapezoidal block 13, driving the moving plate 11 and the insert block 12 to move towards the groove. The insert block 12 is inserted into the slot of the first cutting blade 8.

Limit rod 19 ensures the straightness of movement and realizes precise adjustment of tool height.
