Abstract

The invention discloses a lathe knife rest. The lathe knife rest comprises a knife rest upper plate, a knife rest lower plate and a connecting component which is fixedly connected between the knife rest upper plate and the knife rest lower plate, wherein the knife rest upper plate and the connecting component are of concentric square structures; the plane area of the connecting component is smaller than that of the knife rest upper plate; a plurality of fastening bolts are arranged at the positions close to the edge of the knife rest upper plate in the manner of penetrating through the knife rest upper plat; a spring is arranged at each fastening bolt on the lower surface of the knife rest upper plate and is arranged around the fastening bolt, and a planar cushion is arranged at the joint on the lower part of the spring. Compared with the prior art, the lathe knife rest provided by the invention has the advantages that a structure for protecting a knife handle is provided, the knife handle is more tightly clamped, and the service life of the knife handle is prolonged.

Description

A kind of lathe saddle

Technical field

The present invention relates to a kind of machine tool component, particularly a kind of lathe saddle.

Background technology

General horizontal lathe need to be pulled down the handle of a knife on knife rest in the time of tool changing handle, because handle of a knife is to be rotated clamping by the multiple bolts on knife rest, in the course of time, can damage handle of a knife, cause having many indentures or clamping plane injustice on handle of a knife, in use afterwards, there will be and there is no the incomplete situation of clamping, direct result is that shake and mobile occurs handle of a knife in the time of cutting, and affecting cutting precision is even to have an accident.

Summary of the invention

The technical issues that need to address of the present invention are for above-mentioned the deficiencies in the prior art, can extend and provide a kind of the lathe saddle that handle of a knife life ensuring handle of a knife can not be moved.

For solving the problems of the technologies described above, the technical solution used in the present invention is:

A kind of lathe saddle, comprise knife rest upper plate, knife rest lower plate and be fixedly connected on knife rest upper plate and knife rest lower plate between attaching parts, described knife rest upper plate and attaching parts are concentric squares structure, the area of plane of attaching parts is less than knife rest upper plate, through the knife rest upper plate position that keeps to the side, some fastening bolts is set, and at each fastening bolt place of the lower surface of knife rest upper plate, spring is set, spring, around fastening bolt setting, arranges a plane pad in the joint of spring bottom.

Be circular at described plane pad.

On the rebasing end of described plane, there are multiple cannelures.

Compared with prior art, a kind of lathe saddle of the present invention, by the setting of spring shim, prevent set bolt because revolving force produces wearing and tearing and damages handle of a knife, all right further fixing handle of a knife, prevents mobile and shake, extend the service life of handle of a knife, but also can improve cutting quality.

Accompanying drawing explanation

Fig. 1 is side view of the present invention;

Wherein, 1-knife rest upper plate, 2-knife rest lower plate, 3-attaching parts, 4-fastening bolt, 5-spring, 6-plane pad.

The specific embodiment

Describe the preferred technical solution of the present invention in detail below in conjunction with accompanying drawing.

As shown in Figure 1, a kind of lathe saddle of the present invention, comprise knife rest upper plate 1, knife rest lower plate 2 and be fixedly connected on knife rest upper plate 1 and knife rest lower plate 2 between attaching parts 3, described knife rest upper plate 1 and attaching parts 3 are concentric squares structure, the area of plane of attaching parts 3 is less than knife rest upper plate 1, through knife rest upper plate 1 position that keeps to the side, some fastening bolts 4 are set, each fastening bolt 4 places at the lower surface of knife rest upper plate 1 arrange spring 5, spring 5 arranges around fastening bolt 4, in the joint of spring 5 bottoms, a plane pad 6 is set.

Be circular at described plane pad 6.

Described plane pad has multiple cannelures on 6 bottoms.

When clamping handle of a knife, handle of a knife is positioned between knife rest upper plate 1 and knife rest lower plate 2, adjust handle of a knife height, utilize fastening bolt 4 to rotate, fastening bolt 4 touches plane pad 6, spring 5 is elongated, spring 5 can prevent 6 landings of plane pad, for the position of fixed pan pad 6, fastening bolt 4 withstands on plane pad 6 on handle of a knife, fastening jail, plane pad 6 and the laminating of handle of a knife handle body plane, it is maximum that frictional force reaches, therefore, fastness maximum, on plane pad 6 bottoms, having multiple cannelures is in order to have prevented that small iron filings are on handle of a knife, iron filings can be squeezed in cannelure by the revolving force of plane pad 6, avoid plane pad 6 completely not fit and to be squeezed on handle of a knife.

Claims

1. a lathe saddle, comprise knife rest upper plate (1), knife rest lower plate (2) and be fixedly connected on knife rest upper plate (1) and knife rest lower plate (2) between attaching parts (3), described knife rest upper plate (1) and attaching parts (3) are concentric squares structure, the area of plane of attaching parts (3) is less than knife rest upper plate (1), through knife rest upper plate (1) position that keeps to the side, some fastening bolts (4) are set, it is characterized in that: the each fastening bolt (4) at the lower surface of knife rest upper plate (1) locates to arrange spring (5), spring (5) arranges around fastening bolt (4), joint in spring (5) bottom arranges a plane pad (6).

2. a kind of lathe saddle according to claim 1, is characterized in that: be circle at described plane pad (6).

3. a kind of lathe saddle according to claim 1, is characterized in that: described plane pad (6) has multiple cannelures on bottom.
