Abstract

The invention relates to the field of machining equipment and provides a small lathe. The small lathe comprises a lathe bed, a spindle box provided with a spindle, a longitudinal dragging plate connected with the lathe bed through a longitudinal guide rail and a transverse dragging plate connected with the longitudinal dragging plate through a transverse guide rail. The small lathe further comprises a longitudinal cylinder, a transverse cylinder, a longitudinal limiting assembly, a transverse limiting assembly, a conical elastic clamp, a threaded connecting rod and a connecting rod driving assembly, wherein a cylinder rod of the longitudinal cylinder is connected with the rear end of the longitudinal dragging plate and is also connected with the lathe bed, a cylinder rod of the transverse cylinder is connected with the rear end of the transverse dragging plate and is also connected with the longitudinal dragging plate, the longitudinal limiting assembly is located on the front side of the longitudinal dragging plate, and the transverse limiting assembly is located on the front side of the transverse dragging plate. A conical hole matched with the conical elastic clamp is formed in the front end of the spindle. The front end of the threaded connecting rod penetrates through the spindle to be connected with the rear end of the conical elastic clamp in a threaded mode. The small lathe is simple in structure, capable of clamping parts effortlessly and high in efficiency.

Description

technical field

[0001] The invention relates to the field of machining equipment, in particular to a small lathe. Background technique

[0002] The structure of the small lathe can be understood from a kind of instrument lathe disclosed in the utility model of Chinese Patent Application No. 200620107461. Therefore, it is an urgent problem to design a small lathe with simple structure, labor-saving clamping parts and high efficiency. Contents of the invention

[0003] The purpose of the present invention is to overcome the disadvantages of complex structure, labor-intensive clamping and low efficiency of the current lathe components driven by motors and parts clamped by chucks, and to provide a simple structure and labor-saving and efficient clamping parts. Taller small lathes.

[0004] Concrete technical scheme of the present invention is:

[0005] A small lathe, comprising a bed, a headstock with a main shaft, a longitudinal carriage connected to the bed through longit...
