Abstract
The utility model discloses a lower roll angle adjusting device of a tubular bar straightening machine and belongs to the technical field of tubular material straightening machines. The lower roll angle adjusting device of the tubular bar straightening machine comprises a power transmission mechanism, a lower straightening roll angle adjusting mechanism and a locking mechanism, and is characterized in that a motor (1) with a encoder drives a first cylindrical gear (5) and a second cylindrical gear (6) both arranged on a supporting seat (2) to rotate through a bevel gear (3) arranged on the supporting seat (2) in a transmission mode. The second cylindrical gear (6) is meshed with a sector gear (8) arranged on a roller seat (12), the roller seat (12) is arranged on a machine seat (18) through a thrust bearing (14), and the upper face of the machine seat (18) is connected with a roller plate (9) through bolts (13). A lower straightening roll (11) is installed on the roller plate (9) through a left shaft bearing seat (10) and a right shaft bearing seat (10'), the top end arc face of a piston rod (16) of a hydraulic locking cylinder (15) arranged on the machine seat (18) abuts against a circumferential face of the roller seat (12). The lower roll angle adjusting device of the tubular bar straightening machine has the advantages of being fast, high in angle-adjusting accuracy, large in angle-adjusting range, and convenient to install.
Description
Technical field
The utility model belongs to the tube bar straightening machine technical field, is specifically related to a kind of lower roll reclining apparatus of tube bar straightening machine.
Background technology
At present, what tube bar straightening machine lower roll reclining apparatus generally adopted both at home and abroad is worm-and-wheel gear, lock with nut after regulating, the shortcoming that this employing Worm Wheel System carries out mechanism's existence of angle modulation is that fit clearance is often larger, be difficult to obtain desirable smoothing roll and adjust precision, finally affect bar to the requirement of flattening precision.
Summary of the invention
The utility model purpose provides a kind of lower roll reclining apparatus of tube bar straightening machine of new construction, can effectively overcome the shortcoming that prior art exists.
The utility model purpose is such realization, as shown in Figure 1, it comprises power drive mechanism, lower smoothing roll angle adjusting mechanism and retaining mechanism, it is characterized in that driving the first roller gear 5 and 6 rotations of the second roller gear that are installed on the bearing 2 with the motor 1 of encoder by the Bevel Gear Transmission 3 that is installed on the bearing 2, the second roller gear 6 is meshed with sector gear 8 on being installed in roller seat 12, roller seat 12 is installed on the support 18 by thrust bearing 14, be connected with roller dish 9 by bolt 13 above the roller seat 12, lower smoothing roll 11 is by Y-axis bearing 10,10 ＇ are installed in above the roller dish 9, and the periphery that is installed in the top cambered surface of piston rod 16 of the hydraulic plunger type locking cylinder 15 on the support 18 and roller seat 12 is inconsistent.
Advantage of the present utility model and good effect are: the large shortcoming of fit clearance when effectively having overcome Worm Wheel System in the prior art, can realize the angle of smoothing roll under the fine adjustment reaching the requirement of flattening precision, simultaneously, mechanism is simple, and reliable, cost is lower.
Description of drawings
Fig. 1 is organigram of the present invention, and Fig. 2 is the top view of Fig. 1.Among the figure: 1-motor, 2-bearing, 3-Bevel Gear Transmission, 4-bearing, the 5-the first roller gear, the 6-the second roller gear, 7-bearing, 8-sector gear, 9-roller dish, 10,10 ＇-left and right bearing block, 11-lower smoothing roll, 12-roller seat, 13-bolt connects, 14-thrust bearing, 15-hydraulic plunger type locking cylinder, 16-piston rod, 17-bearing, 18-support, 19-bolt connects.
The specific embodiment
The specific embodiment: as shown in Figure 1, carry encoder EAM58C on motor 1 axle, the aligning angle of the lower smoothing roll of in advance needs being regulated by encoder is accurately located, when needs adjustment aligning angle, starter motor 1 drives Bevel Gear Transmission 3, drive the first and second roller gears 5,6 rotate, drive the sector gear 8 of installing on the roller seat 12 and rotate, and be with action roller dish 9 and lower smoothing roll 11 to rotate together, reach the purpose of regulating lower smoothing roll angle.After adjusting lower smoothing roll angle, roller seat 12 lockings, guaranteed the stable of angle modulation position by hydraulic plunger type locking cylinder 15.When the aligning angle need to be readjusted, at first oppositely adjust hydraulic plunger type locking cylinder 15, thereby with roller seat 12 releases, then repeat said process and got final product angled reorientating.If need oppositely to adjust, only need reset and carry encoder on the motor shaft, repeat said process and get final product.
