Abstract
This invention discloses a lathe center for turning a large tube. The lathe center comprises a head tip (7) and a tail tip (8) and is characterized by further comprising two circular workpieces (1) for fixing and supporting. A central hole is formed in the central position on the bottom of each circular workpiece (1). The head tip (7) and the tail tip (8) are connected with the central holes of the circular workpieces (1), respectively. Adjusting bolts are arranged on the side wall of each circular workpiece (1). The circular workpiece (1) connected with the head tip (7) is connected with a horizontal bar (5) through a fixed bolt (4). The horizontal bar (5) is fixedly connected with a driving lever driven by a disk chuck. The lathe center with such a structure can quickly locate the central line of a seamless tube with a large diameter and is convenient for machining.
Description
Technical field
The present invention relates to a kind of top center device, particularly relate to a kind of turning large effective top center device.
Background technology
Mechanical processing process often will carry out processing excircles, cut groove etc. larger-diameter seamless pipe.The wall thickness of usual seamless pipe is thicker, and the wall thickness disunity of each model seamless pipe, add the machining center line problem being difficult to man-hour solve workpiece.
Summary of the invention
The object of the invention is to solve in seamless pipe process, machining center line is difficult to the problem determined, provides a kind of device of quick position seamless pipe center line.
The technical solution used in the present invention is: a kind of turning large effective top center device, comprise head top top with tail, also comprise two and play annular workpieces that is fixing and supporting role, described annular workpieces bottom centre position is provided with centre bore, the top centre bore that be respectively connected annular workpieces top with tail of described head, described annular workpieces sidewall is provided with adjusting bolt; Describedly connect horizontal bar with the top annular workpieces be connected of head by set bolt, the affixed driving lever stirred by floral disc of described horizontal bar.
As a further improvement on the present invention, describedly the annular workpieces that be connected top with tail is greater than with the diameter of the top annular workpieces be connected of head.
As a further improvement on the present invention, described horizontal bar 5 both sides are respectively provided with the screw of some connection driving levers.
The beneficial effect that the present invention adopts is: the top center device using this structure, can the center line of the larger-diameter seamless pipe of quick position, convenient processing.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Shown in figure: 1 annular workpieces, 3 adjusting bolts, 4 set bolts, 5 horizontal bars, 6 driving levers, 7 heads are top, and 8 tails are top.
Detailed description of the invention
Below in conjunction with Fig. 1, the present invention is described further.
As shown in Figure 1, a kind of turning large effective top center device, comprise head top 7 and tail top 8, also comprise two and play annular workpieces 1 that is fixing and supporting role, described annular workpieces 1 bottom centre position is provided with centre bore, head top 7 is connected the centre bore of annular workpieces 1 respectively with tail top 8, and annular workpieces 1 sidewall is provided with adjusting bolt 3; The annular workpieces 1 be connected with head top 7 connects horizontal bar 5 by set bolt 4, the affixed driving lever 6 stirred by floral disc of horizontal bar 5.
For the ease of processing, be greater than the annular workpieces that be connected top with tail with the diameter of the top annular workpieces be connected of head.
In order to improve this equipment applicability, increase the range of work, horizontal bar 5 both sides are respectively provided with the screw of some connection driving levers.
This device is following work: navigate on lathe with the front and back on head and tailstock top 7 and 8.Materials in the tube are connected on annular workpieces 1 and fix by adjusting bolt 3.Fix on Yi Transverse rod 5 ， Transverse rods at the ring 1 external application set bolt 4 of head one end and fix a dead man stirred by floral disc 6, materials in the tube are rotated and cuts.
Those skilled in the art should know; protection scheme of the present invention is not limited only to the above embodiments; various permutation and combination and conversion can also be carried out on the basis of above-described embodiment; under the prerequisite without prejudice to spirit of the present invention, the various conversion that the present invention carries out all are dropped in protection scope of the present invention.
Claims (3)
1. a turning large effective top center device, comprise head top (7) and tail top (8), it is characterized in that also comprising two plays annular workpieces (1) that is fixing and supporting role, described annular workpieces (1) bottom centre position is provided with centre bore, described head top (7) top with tail (8) are connected the centre bore of annular workpieces (1) respectively, and described annular workpieces (1) sidewall is provided with adjusting bolt (3); The annular workpieces (1) that described top with head (7) are connected connects horizontal bar (5) by set bolt (4), the affixed driving lever (6) stirred by floral disc of described horizontal bar (5).
