Abstract
The utility model relates to a tail frame device of a numerical-controlled pipe drilling machine. A slider arranged at the bottom of a tail frame matches with a linear guide rail of a machine body, two ends of a spindle are erected on the case wall of a tail frame case, a chuck is mounted at the front end of the spindle, a gear further arranged at the bottom of the tail frame is meshed with a rack on the machine body, and the gear is driven by a motor mounted on the tail frame. The slider is arranged at the bottom of the tail frame and matches with the linear guide rail on the machine body, simultaneously the gear is driven by the motor to be meshed with the rack on the machine body, and the motor is controlled by a numerical control platform, thereby the tail frame can be accurately positioned at a required position, then the tail frame is firmly locked on the machine bed via a hydraulic locking device to prevent vibration and deviation during drilling.
Description
Technical field
The utility model relates to field of machine tool equipment, in particular for the numerical control drilling machine of processing pipe part areole.
Background technology
Pipe parts such as boiler header need be processed a lot of through holes or blind hole on the tube wall of pipe, the pipe fitting numerical control drilling machine of the applicant's research and development is clamped in the two ends of pipe fitting on the workbench by rotating chuck, the drilling platform movably is arranged on the workbench, the drilling platform is provided with the clamp assemblies and the drill unit assembly of processing pipe fitting, after clamp assemblies is fixing pipe fitting is carried out outer wall boring processing.But the mechanical chuck of installing on the tailstock device of present fixed fitting tail end, rigidity is stronger, easily the pipe fitting that is held is caused damage; Though tailstock can carry out position adjustments by artificial rotation regulating wheel on lathe bed, the manual operations time is long, labour intensity is big, and can't be effectively fixing on lathe bed, causes adding pipe fitting vibration in man-hour, causes the damage of equipment and part.
The utility model content
The applicant is low at above-mentioned existing pipe fitting numerical control drilling machine tailstock device manual adjustment method efficient, can't satisfy the automation requirement, and the rigidity clamping easily causes shortcomings such as pipe fitting damage, a kind of tailstock device of pipe fitting numerical control drilling machine is provided, can make things convenient for accurately and on lathe bed, move, and steadily flexible clamping pipe fitting end.
The technical scheme that the utility model adopted is as follows:
A kind of tailstock device of pipe fitting numerical control drilling machine, be provided with the slide block that cooperates with the lathe bed line slideway in described tailstock bottom, the main shaft two ends are erected on the tank wall of tailstock case, front-end of spindle is equipped with chuck, also be provided with gear is meshed with tooth bar on the lathe bed in described tailstock bottom, described gear is by motor-driven, and described motor is installed on the tailstock.It is further characterized in that:
Be provided with locking device in described tailstock bottom, described locking device comprises and decides the oil cylinder that piece is fixedlyed connected, and is fixed with motion block at the axis of the piston of described oil cylinder, described decide piece and motion block respectively with lathe bed on the locking strip side adjacency that is provided with;
Described chuck is an oild chuck.
The utility model is provided with slide block in the tailstock bottom, match with the line slideway on the lathe bed, be meshed with tooth bar on the lathe bed by motor-driven gear simultaneously, and motor is controlled by the numerical control console, therefore can accurately tailstock be positioned to needed position; Then by hydraulic locking apparatus with firm being locked on the lathe bed of tailstock, prevent that drilling when work from vibration and skew taking place; The utility model adopts oild chuck replacement mechanical chuck that pipe fitting end is carried out clamping, because hydraulic pressure is steadily reliable, speed is slowly even, therefore can avoid rigid mechanical clamping impulsive force big, the drawback of fragile pipe fitting end.
Description of drawings
Fig. 1 is a cutaway view of the present utility model;
Fig. 2 is a front view of the present utility model;
Fig. 3 is the amplification view at A place among Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1 and Figure 2, passive rotary main shaft 2 is installed in the through hole of tailstock case 4 by two ends circular cone roller bearing 3, end at passive rotary main shaft 2 is connected with rotating chuck 1, rotating chuck adopts oild chuck, control and drive by Hydraulic Station, realization is to the clamping of pipe fitting tail end, and the passive pipe fitting of following is rotated.Oild chuck 1 and hydraulic control technology are prior art, are common in the oild chuck that the numerically controlled lathe clamping part uses.The bottom of tailstock is provided with the slide block 8 that matches with the line slideway 14 that is provided with on the lathe bed, and drive the gear 6 of bottom by motor 5, reductor 7 and be meshed, thereby tailstock can move freely on line slideway 14 and accurately locate with tooth bar 13 on the lathe bed.
As shown in Figure 3, on lathe bed, be fixed with the locking strip 15 that parallels with line slideway 14, correspondence position is provided with hydraulic locking apparatus 9 in the bottom of tailstock, locking device 9 comprise cross over be arranged on locking strip 15 both sides decide piece 12 and motion block 11, the cylinder body of hydraulic jack 10 is fixed on to be decided on the piece 12, and motion block 11 is fixed on the piston rod of hydraulic jack 10 by nut.After tailstock moves to assigned address, the numerical control console by hydraulic control with the withdrawal of the piston rod of hydraulic jack 10, thereby will strain motion block 11, clamp the two sides of locking strip 15, realization locking position with deciding piece 12.When the tailstock needs were mobile, the piston rod of hydraulic jack 10 stretched out, and loosens motion block 11, unlocks.
More than describing is to explanation of the present 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 spirit of the present utility model, the utility model can be done any type of modification.
