Abstract

The invention relates to a stable lathe jacking tip comprising an assembling shaft, a jacking head and pressing covers. The jacking head is a cone, the small end of the jacking head is a flattened end surface, the large end of the jacking head is provided with a stepped hole, one end of the assembling shaft is inserted into the stepped hole, the assembling shaft and the jacking tip are connected through two bearings, the outer sides of the bearings are provided with the pressing covers, and the stepped hole of the jacking head is a through hole. The stable lathe jacking tip is simple in structure and wide in trial range and is capable of clamping steel pipes with large diameters effectively, producing cost is reduced, and producing efficiency and product quality are improved.

Description

A kind of stable type centre for lathe
Technical field
The present invention relates to the field of plant equipment, especially a kind of stable type centre for lathe.
Background technology
Steel pipe for the production of oil cylinder needs to carry out chamfer machining before welded flange, when adopting traditional lathe to carry out chamfer machining, steel pipe one end is needed to be clamped on chuck, the top of other end tail stock is withstood, due to the specification of steel pipe to be processed from diameter 60-220mm not etc., and the external diameter of engine lathe tailstock centre is maximum only has 40mm, so top top is less than steel tube inner hole, the effect of effectively clamping can not be played, and long being clipped on chuck of steel pipe can produce degree of disturbing owing to being affected by gravity, cause and beat, cannot processing operation be carried out.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome above-mentioned middle Problems existing, provide a kind of stable type centre for lathe.
The technical solution adopted for the present invention to solve the technical problems is: a kind of stable type centre for lathe, comprise assembled shaft, top and gland, described top is cone, top small end is flat end face, the large end in top is provided with shoulder hole, and assembled shaft one end is inserted in shoulder hole, is connected between assembled shaft with top by two bearings, outside bearing, gland is housed, the shoulder hole in described top is through hole.
The invention has the beneficial effects as follows: described a kind of stable type centre for lathe, structure is simple, and scope on probation is large, can effectively clamp large diameter steel pipe, reduces production cost, improves production efficiency and product quality.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the overall structure schematic diagram of a kind of stable type centre for lathe of the present invention.
Accompanying drawing acceptance of the bid note is described below: 1, assembled shaft, 2. gland, 3. screw, 4. comes directly towards, 5. bearing.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of stable type centre for lathe as shown in Figure 1, comprise assembled shaft 1, top 4 and gland 2, top 4 is cone, coming directly towards 4 small ends is flat end face, top 4 greatly end is provided with shoulder hole, assembled shaft 1 one end is inserted in shoulder hole, is connected, gland 2 is housed outside bearing between assembled shaft 1 with top 4 by two bearings 5; Shoulder hole in top 4 is through hole.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
