Abstract
The device for cutting off the bar stock without stopping is mounted on a lathe and comprises a self-centering chuck (1) for clamping the bar stock (2), a cutter (6) for cutting off the bar stock, a transverse carriage (10) for enabling the cutter to transversely move, a longitudinal carriage (12) for enabling the cutter to longitudinally move, and a cutter holder (7) for mounting the cutter on the longitudinal carriage. The support plate has the advantages that the support plate has a supporting effect on the bar stock, the bar stock cannot shake due to the cutting force of the cutter in the process of cutting off the bar stock, so that the length of the bar stock extending out of the chuck can be several times of the length of a workpiece, and when one workpiece is cut off, the transverse carriage and the longitudinal carriage only need to be moved, the cutting can be repeatedly performed without stopping, and the working efficiency is greatly improved; the shaft sleeves with different diameters can be replaced, so that workpieces with different diameters can be processed.
Description
Technical Field
The utility model relates to a device for cutting off bar stock without stopping.
Background
The blanking process of the workpiece such as the short shaft is to cut long bars (or round tubes) into short bars with the same length, when the bars are cut on a lathe, the bars are clamped by the self-centering chuck, the bars are cut by the separating knife, the separating knife is close to the centering chuck, so that moment generated by the separating knife to the bars in the cutting process is not large, the bars do not shake, the separating knife is not easy to damage (the separating knife can be broken when the bars shake), but after each section is cut, the self-centering chuck is required to be stopped, the bars are pulled out from the self-centering chuck for one section, the self-centering chuck is clamped again, and the working efficiency is low.
Disclosure of Invention
Aiming at the defects, the utility model provides a device for cutting off bars without stopping, which can greatly reduce the stopping times of a lathe in the cutting process of the bars and improve the working efficiency.
The technical scheme of the utility model is that the device for cutting off the bar stock without stopping comprises a self-centering chuck 1 for clamping the bar stock 2, a cutter 6 for cutting off the bar stock, a transverse carriage 10 for enabling the cutter to transversely move, a longitudinal carriage 12 for enabling the cutter to longitudinally move, and a cutter frame 7 for enabling the cutter to be mounted on the longitudinal carriage.
When the self-centering chuck is used, a bar is clamped by the self-centering chuck, the right end of the bar passes through the shaft sleeve, the lathe spindle is started, the self-centering chuck connected with the lathe spindle rotates, the transverse carriage is moved leftwards to enable the cutter to have a specified distance from the right end of the bar, the longitudinal carriage is moved again to enable the cutter to advance to cut off the bar, and then the cutter is retracted; repeating the above operation again, namely moving the transverse carriage leftwards to enable the cutter to have a specified distance from the right end of the bar, moving the longitudinal carriage to enable the cutter to advance to cut off the bar, and then retracting the cutter.
The utility model has the beneficial effects that the supporting plate has supporting effect on the bar stock, the cutting force of the separating knife can not shake the bar stock in the process of cutting off the bar stock, thus the length of the bar stock extending out of the chuck can be several times of the length of a workpiece, and when one workpiece is cut off, the bar stock can be repeatedly cut off only by moving the transverse carriage and the longitudinal carriage without stopping, thereby greatly improving the working efficiency; the shaft sleeves with different diameters can be replaced, so that workpieces with different diameters can be processed.

Fig. 1 is a schematic structural view of the present utility model.
Fig. 2 is a view in the direction a of fig. 1.
The reference signs are as follows: 1-self-centering chuck, 2-bar, 3-axle sleeve, 4-bearing plate, 5-base, 6-cutter, 7-knife rest, 8-first transverse guide rail, 9-second transverse guide rail, 10-transverse carriage, 11-longitudinal guide rail, 12-longitudinal carriage, 13-hem, 14-waist, 15-bolt.
Detailed Description
The device for cutting off the bar stock without stopping comprises a self-centering chuck 1 for clamping the bar stock 2, a cutter 6 for cutting off the bar stock, a transverse carriage 9 for enabling the cutter to transversely move, a longitudinal carriage 12 for enabling the cutter to longitudinally move, a cutter frame 7 for mounting the cutter on the longitudinal carriage, a first transverse guide rail 8 and a second transverse guide rail 9 respectively arranged at the two longitudinal ends of the transverse carriage, a longitudinal guide rail 11 arranged on the transverse carriage, a support plate 4 fixedly arranged on the transverse carriage along the longitudinal guide rail, a shaft sleeve 3 connected in the support plate and coaxial with the self-centering chuck, and a clearance fit between the shaft sleeve and the bar stock.
The support plate may be screwed to the waist 14 of the transverse carriage as shown in broken lines in fig. 2, but this requires tapping of the waist 14 of the transverse carriage.
In order to not change the structure of the transverse carriage, the bottom of the supporting plate is connected with a strip-shaped base 5, two ends of the base are respectively provided with a folded edge 13 with 90 degrees, the folded edges are sleeved at two longitudinal ends of the transverse carriage, bolts 15 are screwed in the folded edges, and the base can be installed and fixed on the transverse carriage by screwing the bolts.
In order to adapt to the processing of workpieces with different diameters, one end of the shaft sleeve is provided with a flange, and the flange is connected with the supporting plate through a screw, so that the shaft sleeve with different diameters can be conveniently replaced.
