Abstract
The utility model relates to a lift regulation mechanism for travelling wheels of a rotary machine tool. A servo motor and a pull rod hydraulic cylinder are arranged on a rack, the servo motor is connected with a screw rod through a coupler, a screw nut is fixed on a support plate and is matched with the screw rod, a pull rod of the pull rod hydraulic cylinder is connected with the support plate, and the travelling wheels are fixedly arranged under the support plate through a travelling wheel frame. According to the lift regulation mechanism, the servo motor is fixed on a travelling drive wheel rack, a ball screw rod is driven by the servo motor to rotate, the rotation of the ball screw rod is transformed into linear motion through the screw nut under the guiding action of a linear guide rail pair, the support plate is driven to do lifting motion, the travelling wheels are fixed on the support plate through the wheel frame, and the lift regulation of the traveling wheels is completed by the rotation of the servo motor. Moreover, the pull rod hydraulic cylinder is further arranged on the rack and is connected with a connecting seat on the support plate, and on the basis of large hydraulic transmission power and high transmission accuracy of the servo motor, the pull rod hydraulic cylinder and the connecting seat jointly work to realize accurate and stable regulation on the lifting of the traveling drive wheels.
Description
Technical field
The utility model relates to field of machine tool equipment, in particular for the rotary machine tool of processing large-diameter workpiece.
Background technology
Large-diameter workpiece such as hauling rope, coastal waters floating structure, radiotelescope and pressure vessel etc.; Need be at some guide pass of outer edge surface Surface Machining of structural I-beam; Because there is the problem of two aspects in the special equipment of these guide pass of processing at present, is in machined surface and green surface transition on the one hand, perhaps is exactly in the processing plane transition that high low head is arranged; The adjusting of can not going up and down of its running wheel, the plane precision that causes like this processing does not reach requirement; Though be that some equipment running wheels have the structure of going up and down to regulate on the other hand; But that have or be to adopt pure hydraulic cylinder to regulate, or be to adopt pure servomotor to regulate, during with pure hydraulic cylinder adjusting; The height that goes up and down can not accurately be controlled; When regulating with pure servomotor, because its lathe frame is heavier relatively, there are some problems again in the power aspect.
The utility model content
The applicant can not regulate the up-down of running wheel in guide pass processing to above-mentioned existing relevant process equipment; Perhaps be exactly when running wheel goes up and down to regulate, can not reach required precision and power requirement; The guide pass precision that finally causes being processed does not reach the shortcoming of requirement; A kind of road wheel lifting regulating mechanism of rotary machine tool is provided; Adopt the up-down of servomotor and pull bar hydraulic cylinder driven in common running wheel, both utilized the high characteristics of driven by servomotor precision, combine the big characteristics of Driven by Hydraulic Cylinder power again; Make the guide pass processing of workpiece can reach certain precision, the processing platform of a precise and high efficiency is provided for the processing of workpiece guide pass.
The technical scheme that the utility model adopted is following:
A kind of road wheel lifting regulating mechanism of rotary machine tool, servomotor and pull bar hydraulic cylinder are installed on the frame, and servomotor is connected with leading screw through shaft coupling, and screw fixing on the supporting plate matches with leading screw; The pull bar of pull bar hydraulic cylinder is connected with supporting plate, is fixed with road wheel in the supporting plate bottom through the walking wheel carrier.
The servomotor of the utility model is fixed on the running wheel frame, drives ball screw by servomotor and rotates, and under the guide effect of line slideway auxiliary, is converted into rectilinear motion to the rotation of ball screw through screw, drives supporting plate and does elevating movement.On supporting plate, also be fixed with Connection Block, road wheel also is fixed on the supporting plate through wheel carrier.Like this, just accomplish the adjusting that road wheel goes up and down through the rotation of servomotor.In addition, the pull bar hydraulic cylinder is installed also on frame, links to each other with Connection Block on the supporting plate, the big characteristics with servomotor transmission precision property of integrated hydraulic transfer motion power, the adjusting of running wheel up-down is accomplished in acting in conjunction.
Description of drawings
Fig. 1 is the front view of the utility model, broken section.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.
As shown in Figure 1, the utility model comprises servomotor 1, shaft coupling 2, bearing block 3, frame 4, ball wire bar pair 5, pull bar hydraulic cylinder 6, oil cylinder earrings 7, line slideway auxiliary 8, link 9, supporting plate 10, wheel carrier 11, road wheel 12.
Servomotor 1 is installed on the frame 4 with pull bar hydraulic cylinder 6; The leading screw 5-1 motion that servomotor 1 drives through shaft coupling 2; The pull bar of pull bar hydraulic cylinder 6 is fastened on the link 9 on the supporting plate 10 through oil cylinder earrings 7; The screw 5-2 of ball wire bar pair also is fixed on the supporting plate 10, and under the guide effect of line slideway auxiliary 8, servomotor 1 is done elevating movement with the pull bar hydraulic cylinder 6 common supporting plates 10 that drive.Road wheel 12 is installed on the walking wheel carrier 11, and wheel carrier 11 is fixed on the supporting plate 10 through some guiding mechanisms and link thereof, also drives walking crop rotation elevating movement when supporting plate moves like this.
When real work, mainly drive the leading screw 5-1 of ball screw assembly, by servomotor 1, drive screw 5-2 and supporting plate 10, wheel carrier 11, road wheel 12 and do elevating movement, utilize the characteristics of servomotor transmission precision property, make it obtain displacement accurately; And pull bar hydraulic cylinder 6 is done driven action, utilizes the big characteristics of hydraulic drive power, balance road wheel 12 stressed, thus can accomplish the adjusting purpose that the running wheel of steady precision goes up and down.Owing to adopted pull bar hydraulic cylinder 6, therefore can the very big load of load-bearing, avoided the direct stressed failure by shear power that on leading screw and screw, produces.
More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of the spirit of the utility model, the utility model can be done any type of modification.
