Description

Technical Field

[0001] The utility model relates to the technical field of numerical control lathes, and particularly relates to a high-precision and multi-functional numerical control lathe fixture. Background Art

[0002] Numerical control lathes are one of the most widely used numerical control machine tools. It is mainly used for the cutting processing of the inner and outer cylindrical surfaces of shaft parts or disc parts, the inner and outer conical surfaces with any cone angle, the complex revolving inner and outer curved surfaces, and cylindrical and conical threads, etc., and can perform grooving, drilling, reaming, boring and other operations. When processing workpieces on a numerical control lathe, a fixture is required to limit and fix them.

[0003] After searching the Chinese patent "A multi-functional fixture for a numerical control lathe", the publication number is "CN219005315U". This patent can adjust the position of the positioning plate through the cooperation of the chute and the slider, which is convenient for the staff to position workpieces of different sizes. By using the cooperation of the rotating block and the rotating rod, it is convenient for the staff to rotate the positioning screw, saving the staff's time. When the positioning screw rotates, the two positioning clamping plates can approach each other to clamp and position the workpiece, increasing the stability during workpiece processing, and solving the problem that most of the fixtures of the current numerical control lathes are fixed and cannot adjust the position of the fixture, making it inconvenient to clamp and position workpieces of different sizes. However, when this device is used, the fixing effect on workpieces of different shapes and sizes is poor, it is inconvenient to stably limit and fix workpieces of different shapes and sizes, and the use effect of the device is reduced.

[0004] Therefore, a high-precision and multi-functional numerical control lathe fixture is proposed to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a high-precision and multi-functional numerical control lathe fixture to solve the above problems, and improve the problem of inconveniently stably limiting and fixing workpieces of different shapes and sizes.

[0006] The utility model realizes the above purpose through the following technical solutions. A high-precision and multi-functional numerical control lathe fixture includes a workbench, and a tool is arranged at the top of the workbench; an installation mechanism for stably limiting and fixing workpieces of different shapes and sizes is arranged at the top of the workbench; wherein, the installation mechanism includes installation blocks arranged on both sides of the top of the workbench, one side of the installation block is rotatably connected with an installation plate, two fixing plates are slidably connected to one side of the installation plate, and a fixing component is arranged on the inner wall of the installation plate.

[0007] Preferably, the mounting mechanism further includes a clamping plate fixedly connected to the outer wall of the fixing plate. Two sliders are fixedly connected to one side of the fixing plate. The sliders are slidably connected to the inner wall of the mounting plate. A limiting plate is slidably connected to the inner wall of the clamping plate, which can quickly limit and fix the workpiece that is inconvenient to be fixed by the three-jaw chuck, and improve the use effect of the device.

[0008] Preferably, several uniformly distributed limiting grooves are formed on the surface of the limiting plate, which can improve the fixing effect between the clamping plate and the limiting plate.

[0009] Preferably, a first threaded rod is threadedly connected to the top end of the fixing plate. One end of the first threaded rod penetrates through the fixing plate and is rotatably connected to the limiting plate. Two telescopic rods are fixedly connected to the top end of the limiting plate, which can drive the two limiting plates to move towards the middle from the upper and lower ends respectively to fix the workpiece.

[0010] Preferably, a bidirectional lead screw is rotatably connected to one side of the inner wall of the mounting plate. The two ends of the bidirectional lead screw are respectively threadedly connected to two of the sliders, which can drive the clamping plates on the two fixing plates to limit and fix the workpiece.

[0011] Preferably, the fixing component includes several uniformly distributed blocks that are slidably connected to one side of the mounting plate. A second threaded rod is rotatably connected to the inner wall of the mounting plate. The second threaded rod is threadedly connected to the blocks, which can drive several blocks to move simultaneously to clamp and fix the workpiece.

[0012] Preferably, a first bevel gear is fixedly connected to one end of the second threaded rod. A second bevel gear is rotatably connected to the inner wall of the mounting plate. The second bevel gear is threadedly connected to the first bevel gear. The second bevel gear cooperates with several first bevel gears to drive several second threaded rods to rotate.

[0013] Preferably, a fixing rod is fixedly connected to one side of the second bevel gear. One end of the fixing rod is fixedly connected to a worm gear. A worm is meshed with one side of the worm gear, which can drive the second bevel gear to rotate and lock and limit it.

[0014] The beneficial effects of the present utility model are:

[0015] 1. By setting up the installation mechanism, when the fixture fixes the workpiece during use, rotating the bidirectional lead screw drives the clamping plates on the two fixed plates to move from the upper and lower ends towards the middle respectively to fix and clamp the workpiece. The groove on the inner wall of the clamping plate is trapezoidal, which can quickly and stably clamp and limit the workpiece. When fixing some smaller workpieces, rotating the first threaded rod drives the limiting plate to move towards one end to clamp it. The limiting groove on the surface of the limiting plate can improve the limiting effect of the limiting plate on the workpiece. The two telescopic rods can stably support the limiting rod and improve the clamping effect of the limiting plate, enabling the fixation of workpieces with different shapes and sizes and enhancing the diversity of workpiece clamping by the device.

[0016] 2. By setting up the fixing component, when installing and fixing the workpiece, rotating the second bevel gear drives several first bevel gears to rotate. The first bevel gear drives the second threaded rod to cooperate with the clamping block so that the clamping block can move from the outside towards the middle simultaneously to quickly clamp and fix the workpiece. The worm can drive the second bevel gear on one side of the worm wheel to rotate. The worm wheel and the worm cooperate with each other to have a certain self-locking property, preventing it from loosening when the clamping block fixes the workpiece, and enabling the quick fixation of the workpiece to improve the use effect of the device.
