Abstract
The utility model discloses a screw rod comprising a rod body. The rod body is provided with threads, two ends of the rod body are reducing footstep-shaped, and the cross section of the last footstep is square. For the screw rod, the structure is simple, the implement is easy, and the stability is improved greatly, thereby further improving the production efficiency of a machine tool.
Description
Technical field
The utility model relates to lathe and uses the leading screw field, relates in particular to a kind of leading screw.
Background technique
Lathe is the machine that metal blank is processed into machine parts, and it is a machine of making machine, so be called " machine tool " or " toolroom machine " again, is called for short lathe traditionally, and lathe plays significant role in the construction of national economic modernization.In lathe, need use leading screw production, the leading screw poor stability of prior art influences the production of lathe.
The model utility content
The utility model purpose provides a kind of leading screw, with the problem of the leading screw poor stability that solves prior art.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of leading screw includes the thick stick body, and described thick stick forms the multi-turn screw thread on one's body, it is characterized in that: described thick stick body two ends are the step-like of undergauge, and wherein the afterbody step profile section is square.
The utility model is simple in structure, is easy to realize, can improve the stability of leading screw by step-like thick stick end, and the step-like leading screw end section of afterbody is square simultaneously, can guarantee that leading screw closely contacts not slide relative with lathe.The utility model has improved the stability of leading screw greatly, has further improved the manufacturing efficiency of lathe.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1.A kind of leading screw includes thick stick body 1, forms multi-turn screw thread 2 on the thick stick body 1, and thick stick body 1 one ends are the step-like of undergauge, and wherein afterbody step 3 cross sections are square.
