Abstract
The utility model belonging to a three-shaft vertical joint screw rolling machine which is characterized in that the slide blocks with cylinder arranged at the tail are assembled on three concentrically uniformly distributed guideways of processing disc; the head of each slide block is vertically arranged by a transmission shaft with the same screwing wheel arranged at the upper end; each transmission shaft is connected with the output shaft relevant to the reduction gearbox of the drive motor fixed on the workbench; a vertical adjusting rod where the workpieces can be placed is arranged on the table-board of the reduction gearbox in the workbench relevant to the circle center of the working disc. The utility model has a simple entirety structure, scientific sound design and good in-phrase processing effect, overcomes the abuse of existing machine tool and screw machine joints, has a high production efficiency and is especially suitable for the screwing rolling processing of the hollow core workpieces such as hydraulic joints and thin-wall hollow core workpieces.
Description
Technical field
The utility model belongs to the screw-rolling machine of field of machining, especially a kind of three shaft vertical joint screw-rolling machines that are exclusively used in the joint rolled thread.
Background technology
Screw-rolling machine is the special-purpose machinery that workpiece is carried out rolled thread, generally is that two cylindrical die rolls of symmetry push rolled thread to therebetween workpiece.For real mandrel class workpiece, can on screw-rolling machine, carry out rolled thread, also can rolled thread on lathe.Rolled thread on screw-rolling machine, pitch is guaranteed, and the screw stress effect is good; Rolled thread on lathe, thread size does not guarantee that screw cuts down, stress effect is relatively poor.For the hollow workpiece of this class of hydraulic joint, adopt lathe and screw-rolling machine rolled thread, make the hollow workpiece deformation easily, production efficiency is lower, and qualification rate is lower.Especially for the thin-wall hollow workpiece, all the more so.And, by understanding, do not find as yet for the special-purpose screw-rolling machine of this class hollow workpiece rolled thread.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, efficient height, the three shaft vertical joint screw-rolling machines that are exclusively used in the joint rolled thread that can ideally carry out rolled thread to the hollow workpiece.
The utility model solves its technical problem and takes following technical scheme to realize:
This three shaft verticals joint screw-rolling machine, by workbench, drive motors, power transmission shaft, reduction box, oil cylinder, the processing dish, cylindrical die roll constitutes, the processing dish is packed on the table surface, it is characterized in that: on three uniform guide rails of processing dish circle level together, all be equipped with the slide block that its afterbody all is equipped with oil cylinder, the head of each slide block all vertically is equipped with the power transmission shaft that its upper end is fixed with identical cylindrical die roll, every power transmission shaft is connected with the corresponding output shaft of reduction box of drive motors in being packed in workbench, and the vertical adjusting lever that can put workpiece thereon is installed on the reduction box table top in the workbench of corresponding scratch diskette home position.
And, the described output shaft that power transmission shaft connected that installs cylindrical die roll for thereon, the bottom all is equipped with the universal drive shaft of bulb.
And, in the upper end of described vertical adjusting lever one rotating disk being installed, workpiece is seated on the rotating disk.
And described power transmission shaft is installed in the head of slide block by bearing.
Advantage of the present utility model and good effect are:
1. adopt the feeding mode of three synchronous interaction cylindrical die rolls of assembling on the processing dish to carry out the workpiece rolled thread, can effectively solve the problem on deformation that the rolled thread workpiece produces, screw stress is good, has guaranteed the rolled thread quality of workpiece.Be particularly useful for the rolled thread processing of hollow workpiece such as hydraulic joint and thin-wall hollow workpiece.
2. overall structure is simple, and design science is reasonable, and synchronous processing is effective, overcome the drawback of existing lathe and screw-rolling machine rolled thread joint workpiece, and production efficiency is higher.
Description of drawings
Fig. 1 is front view of the present utility model (broken section signal);
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is that the B-B of Fig. 2 is to cross-sectional view;
Fig. 4 is that the A-A of Fig. 1 is to schematic cross-section.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
This is exclusively used in three shaft vertical joint screw-rolling machines of joint rolled thread, form by workbench 9 and processing dish 3, the processing dish is packed on the table surface, is shaped on machining hole (not label) at position, the processing dish center of circle, to should also being shaped on through hole (not label) by machining hole on the table top of workbench.
The structure of processing dish and parts thereof is such:
On three uniform guide rails 14 of processing dish circle level together, all be equipped with the slide block 2 that its afterbody all is equipped with oil cylinder 1, the head of each slide block all vertically is equipped with the power transmission shaft 15 that its upper end is fixed with cylindrical die roll 5 by bearing 16, each cylindrical die roll on identical plane and its pitch be consistent, and the diameter of this cylindrical die roll is the integral multiple of the diameter of workpiece 4.Can be on the guide rail of processing dish under the effect of oil cylinder locking phase to interlock.
The structure of the drive unit in the workbench is such:
Be fixed with a reduction box 12 on the base plate 13 in workbench, the deceleration arrangements of reduction box because each gear meshing configuration is comparatively simple, is omitted as shown in Figure 4 in the present embodiment.On the table top 11 of this reduction box, be fixed with a drive motors 10, this drive motors is drawn three vertical output shafts 8 by gear combination on the table top of reduction box, the upper end of these three output shafts all is connected with the power transmission shaft of cylindrical die roll by shaft coupling 17, this output shaft for thereon, the bottom all is equipped with the universal drive shaft of bulb.The one vertical adjusting lever 7 that can put workpiece thereon is installed on the reduction box table top in the workbench of corresponding scratch diskette home position, upper end at vertical adjusting lever is equipped with a rotating disk 6, workpiece is seated on the rotating disk, and rotating disk also rotates thereupon when can be implemented in workpiece by cylindrical die roll driving rotation.This vertical adjusting lever is installed by screw thread and reduction box table top, regulates the height of adjusting workpiece thereby by screw thread vertical adjusting lever is carried out axial displacement.
Operation principle of the present utility model is:
Drive motors is drawn three output shafts that its rotating speed is identical by reduction box on the reduction box table top, this output shaft drives cylindrical die roll and rotates.Vertical adjusting lever supporting workpiece on the table top of reductor.Three uniform oil cylinder linkage driving slide blocks, slide block promotes the cylindrical die roll feeding of its assembling, because output shaft needs to tilt when the cylindrical die roll feeding, therefore adopts universal drive shaft to solve this problem.Three cylindrical die roll interlock feedings are also pushed workpiece rolled thread screw thread, and workpiece rotated on rolling disc and finished rolled thread this moment.After rolled thread was finished, oil cylinder was return, and took out workpiece, carried out the rolled thread of next workpiece.
