Description

Technical Field

[0001] The utility model relates to the technical field of lathes, in particular to a lathe capable of quickly fixing and protecting a workpiece. Background Art

[0002] Lathes are commonly used machine tools for metal processing. Lathes can perform various cutting operations, such as turning, boring, drilling, etc. Lathes can process shapes such as cylinders, cones, spheres, etc. They are widely used and suitable for mass production of parts. The operation is relatively simple, but it requires skilled techniques and experience, which can improve processing efficiency and accuracy.

[0003] When using the existing lathe, it is not convenient to quickly fix the workpiece, and it cannot provide protection for the workpiece on the lathe. When cutting the workpiece, the waste generated by cutting will splash out of the processing area, and the splashing waste will cause damage to the surrounding workers. The lathe is not safe to use. For this reason, we propose a lathe that can quickly fix and protect the workpiece. Utility Model Content

[0004] The purpose of the utility model is to provide a lathe which can quickly complete the fixation and protection of workpieces, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A lathe for quickly completing the fixation and protection of workpieces comprises a lathe plate, two groups of bottom support frames are installed at the bottom of the lathe plate, and a moving assembly is provided in the inner cavity of the lathe plate, the moving assembly comprises two groups of connecting slides, the tops of the two groups of connecting slides are connected to protective frames, and the front ends of the two groups of protective frames are provided with transparent portholes, the tops of the two groups of protective frames are installed with fixing boxes, a lifting tooth plate is vertically slidably connected in the fixing box, the bottom of the lifting tooth plate is located in the inner cavity of the protective frame, and a downward pressing fixing plate is installed at the bottom of the lifting tooth plate.

[0007] Furthermore: the front end outer wall of the fixed box is connected to a reduction motor, the output end of the reduction motor is connected to a rotating shaft, and a rotating gear is sleeved on the rotating shaft, and the rotating gear is meshed and connected with the lifting gear plate.

[0008] Furthermore: the top wall, the bottom wall of the fixed box and the top wall of the protective frame are all provided with openings which are arranged through, and the openings are slidably connected with the lifting gear plate.

[0009] Further: the moving component includes a stepper motor, the stepper motor is located on the right outer wall of the lathe plate, and the output end of the stepper motor is connected to a bidirectional screw rod, two sets of threaded seats are threadedly connected on the bidirectional screw rod, the tops of the two sets of threaded seats are respectively connected to the bottoms of the two sets of connecting slides, and both ends of the upper surface of the lathe plate are provided with limit grooves, and the limit grooves are slidably connected to the connecting slides.

[0010] Furthermore: the lower surface of the pressing fixing plate is provided with an anti-skid pad, and the lower surface of the anti-skid pad is embedded with staggered protrusions.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model can drive the rotating gear on the rotating shaft to rotate through the operation of the reduction motor. Since the rotating gear is meshed and connected with the lifting gear plate, the lifting gear plate drives the pressing fixing plate to move downward, thereby realizing the rapid fixation of the workpiece on the lathe. The operation of the stepping motor can drive the bidirectional lead screw to rotate. After the two groups of threaded seats threadedly connected with the bidirectional lead screw are slidably connected with the connecting slide seat through the limiting groove, the two groups of protection frames can be moved in relative or opposite directions, which can provide protection for the workpiece on the lathe, avoid splashing of waste materials during cutting of the workpiece to cause damage to surrounding personnel, and improve the safety of the lathe.
