Description

Technical Field

[0001] This utility model relates to the field of lathe technology, and in particular to a turret lathe with a stable transmission structure. Background Art

[0002] Existing turret lathes with stable transmission structures consist of a frame, a turret, and cutting tools mounted on the turret. The cutting tools mounted on the turret can machine the outer cylindrical surface of the workpiece. The cutting tools turn the outer diameter according to the set cutting parameters (such as cutting speed, feed rate, etc.), thereby obtaining an outer cylindrical surface that meets the requirements of dimensional accuracy and surface roughness.

[0003] However, when in use, it lacks an additional support structure to suppress vibration. When performing high-precision turning, it is easy to cause dimensional deviations due to vibration. For example, when turning the outer circle of precision shaft parts, the vibration during the cutting process may cause the cutting tool to produce a small runout in the radial direction, resulting in an increase in the cylindricity error of the outer circle. Vibration will also have a serious impact on the surface quality of the workpiece. Without effective damping measures, the relative vibration between the cutting tool and the workpiece will leave vibration marks on the workpiece surface, which will greatly increase the surface roughness. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a turret lathe with a stable transmission structure. After the workpiece is moved by the support block, the second motor drives the second lead screw to rotate, thereby driving the lifting block downward. This causes the spring and damper to move the pad downward to support the bottom surface, providing additional support for the support block. This support force can effectively reduce the vibration of the support block and the workpiece, preventing vibration from causing turning errors or surface roughness that do not meet requirements during high-precision turning. This additional support structure can absorb and suppress vibration, making the machining more stable and ensuring that the machined workpiece has higher precision and better surface quality.

[0013] Beneficial effects

[0014] 1. Compared with existing technologies, this turret lathe with a stable transmission structure, after the workpiece is moved by the support block, can drive the lead screw to rotate via motor two, thereby driving the lifting block downward. This causes the spring and damper to move the pad downward to support the bottom surface, providing additional support for the support block.

The frame 2 is slidably connected. A handle 7 is fixedly connected to the side surface of the glass door 6. An anti-slip sleeve 8 is fixedly connected to the outer surface of the handle 7. A frame 3 is connected through the side surface of the lathe body 1. A transparent window 4 is fixedly connected to the inner wall of the frame 3. A slide groove 22 is provided on the inner surface of the lathe body 1. A hydraulic cylinder 13 is fixedly connected to the inner surface of the slide groove 22. A hydraulic rod 12 is fixedly connected to the output end of the hydraulic cylinder 13. The upper end of the hydraulic rod 12 is fixedly connected to the lower surface of the slider 23. The slider 23 is slidably connected to the inner surface of the slide groove 22.

[0024] The front surface of the slider 23 is rotatably connected to a power turret 24, which is a mature existing technology and will not be described in detail in this document. A frame 28 is slidably connected to the inner surface of the lathe body 1 to support components. A slide rod 25 is fixedly connected to the inner surface of the frame 28 to limit the sliding direction of the support block 21. The outer wall of the slide rod 25 is slidably connected to the support block 21 for placing the workpiece. The support block 21 has mounting holes 20 for mounting and fixing fixture components. A motor 27 is fixedly connected to the inner surface of the frame 28. A lead screw 26 is fixedly connected to the output end of the motor 27 to drive the support block 21 to move. The lead screw 26 and... The bearing block 21 is threaded, and four sleeves 14 are fixedly connected to the side surface of the bearing block 21 for the lifting block 17 to slide inside. The inner surface of the sleeve 14 is fixedly connected to the motor 2 15, and the output end of the motor 2 15 is fixedly connected to the lead screw 2 16. The outer wall of the lead screw 2 16 is threadedly connected to the lifting block 17 for driving the spring 18 and the damper 19 to move. The lower surface of the lifting block 17 is fixedly connected to the spring 18, and the lower surface of the lifting block 17 is fixedly connected to the damper 19 for cooperating with the spring 18 to absorb and buffer vibration.

[0025] Working principle: In use, the fixture assembly is installed and fixed on the support block 21 through the mounting hole 20. Then, the workpiece is fixed on the fixture assembly. Motor 10 drives the lead screw 9 to rotate. Since the lead screw 9 is threadedly connected to the frame 28, the position of the frame 28 within the lathe body 1 is adjusted according to the rotation direction of the lead screw 9, thereby achieving the overall movement of the frame 28. This moves the support block 21, carrying the workpiece, to a suitable machining position. Motor 27 drives the lead screw 26 to rotate. Because the lead screw 26 is threadedly connected to the support block 21, and the support block 21 is restricted to sliding only in a specific direction by the slide rod 25, therefore... The bearing block 21 will be adjusted laterally within the frame 28 to further move the workpiece to the optimal machining position of the power turret 24. After the bearing block 21 has moved the workpiece, the motor 15 inside the sleeve 14 is started. The motor 15 drives the lead screw 16 to rotate. The lead screw 16 drives the lifting block 17 to move downward. When the lifting block 17 moves downward, it drives the spring 18 and the damper 19 to move downward together. Finally, the spring 18 and the damper 19 drive the pad 11 to move downward and support it on the inner bottom surface of the lathe body 1, providing additional support for the bearing block 21 to reduce vibration during machining and ensure machining accuracy and stability.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
