Abstract
The invention relates to the field of machining, in particular to a center bracket of a horizontal machine tool and the horizontal machine tool provided with the center bracket. Disclosed is the center bracket of the horizontal machine tool. The center bracket comprises a bracket seat and a cylindrical clamp. The bracket seat and the cylindrical clamp are fixed by support rods fixed onto an inner wall of the bracket seat. Tail ends of the support rods are provided with roller feet. The roller feet are in contact with the outer side wall of the cylindrical clamp. One of sections at two ends of a cylindrical wall of the cylindrical clamp is provided with multiple uniformly-distributed fixing holes. The center bracket further comprises fixing rods, matching internal diameters of the fixing holes. By adoption of the horizontal machine tool provided with the center bracket, the center of a circle remains unchanged during rotary truning operation of an overall blank roll and is not off the track. The center of a circle of a formed roller and centers of circles at head and tail portions are disposed on the same horizontal line. A product has the same section within the full-length range and high truning precision.
Description
Technical field
The present invention relates to field of machining, particularly relate to horizontal machine tool manufacture field, more specifically relate to the center rest of horizontal machine tool, and be provided with the horizontal machine tool of this center rest.
Background technology
Fig. 1 is the center rest that current horizontal machine tool generally adopts, we can see that its inside is provided with the adjusting rod 2 of three band roller pin 1, current way is placed in flower disc clamp, tailstock and center rest by roller 3 to be processed, because the center of circle of flower disc clamp and tailstock is determined, therefore adjustment three is only needed to be with the length of the adjusting rod of roller pin just by roller leveling, thus can ensure that the roller that length is longer does not bend because of deadweight reason in the processing of car circle.
But, we find in actual application, because the blank cross section of roller is uneven same in length range, its cross section is rendered as irregular circle, therefore, along with the continuous rotation of blank roller in processing, the continuous sideslip in the center of circle, cross section at center rest place, has a strong impact on the car circle homework precision that blank rolls.
Summary of the invention
In order to solve the problem that current horizontal machine tool runs in machining blanks roller, improve car circle homework precision, we disclose a kind of center rest of horizontal machine tool, described center rest comprises bearer carrier, cylindrical shape fixture, described bearer carrier and cylindrical shape fixture are fixed by the support bar being fixed on bearer carrier inwall, the tail end of described support bar is provided with roller pin, and roller pin contacts with the lateral wall of cylindrical shape fixture; The a certain cross section at the barrel two ends of described cylindrical shape fixture is respectively provided with multiple equally distributed fixing hole, also includes the fixed bar mated with fixing hole internal diameter.
The barrel two ends of cylindrical shape fixture mentioned here refer to be positioned at Cylindorical rod to two ends, the cross section, fixing hole place of both sides is round relative to symmetrical section symmetrical.
After blank roller to be processed is put into, fixed bar through fixing hole, props up with the outer wall of blank roller, realizes fixing of blank roller and cylindrical shape fixture.
Fixed bar can be disclosed preferred embodiment bolt in the present invention, also can be the polished rod with locking member.
Preferred as one, a certain cross section at the barrel two ends of described cylindrical shape fixture is respectively provided with the equally distributed fixing hole of even number.
Further, a certain cross section at the barrel two ends of our preferred described cylindrical shape fixture is respectively provided with four equally distributed fixing holes.Such setting both can meet fixing needs, can increase work efficiency again.
Preferred as another kind, described fixed bar is screw rod, and fixing hole is screwed hole accordingly.Thus make adjustment convenient, and fixing rear stability is higher.Here can be full flight screw as required, also can be the screw rod with certain length polished rod, or bolt.
Further, we also preferably also comprise the nut being fixed on screw rod, and described nut is positioned at outside cylindrical shape fixture.Thus improve the stability after fixing further.
Finally, we also disclosed the horizontal machine tool being provided with aforesaid central bracket, wherein center rest, cylindrical shape fixture, flower disc clamp, being centrally located on same level line of tailstock.
Adopt the horizontal machine tool that center rest disclosed in this invention is housed, in the operation of whole blank roller rotating vehicle circle, the center of circle is constant, not sideslip, and the shaping roller center of circle and the center of circle are end to end on a horizontal line.In product length range, cross section is all identical, car circle machining accuracy is high.
Accompanying drawing explanation
Fig. 1 is center rest of the prior art.
Fig. 2 is center rest schematic diagram disclosed in this invention.
Fig. 3 has the horizontal machine tool of center rest disclosed in the present invention for device.
Detailed description of the invention
In order to there be getting to know clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and set forth the present invention further by detailed description of the invention.
For making simplified form, in each figure, only signal has marked part related to the present invention.
As shown in Figure 2, a kind of center rest of horizontal machine tool, described center rest comprises bearer carrier 4, cylindrical shape fixture 5, described bearer carrier and cylindrical shape fixture are fixed by the support bar 6 being fixed on bearer carrier inwall, the tail end of described support bar is provided with roller pin 7, and roller pin 7 contacts with the lateral wall of cylindrical shape fixture; The a certain cross section at the barrel two ends of described cylindrical shape fixture is respectively provided with multiple equally distributed fixing hole, also includes the fixed bar 9 mated with fixing hole internal diameter.
We select bolt as fixed bar 9 in the present embodiment, and correspondingly fixing hole is the screwed hole matched.
During use, we are by center rest device on horizontal machine tool, and concrete referring to Fig. 3, roller 3 to be processed is successively through flower disc clamp 10, center rest 11, tailstock 12.
Then on the standard section, one end of roller to be processed, arrange a scriber 13, live-rollers, constantly adjustment bolt is relative to the screw-in length of screwed hole, and ensure that roller rotates and within one week, do not encounter scriber and be as the criterion, so far the adjustment of bolt is complete.
Normal boot-strap, utilizes a stroke cutter 14 to carry out the operation of car circle.
The integral position of car circle operation central roll does not change, and the center of circle is not with rotation sideslip, and after processing, the length range cross section of product is identical, and precision is high.
