Background technology
When boring machine carries out the bore hole operation, its boring cutter need be in the complete dark scope in hole feed with from the end boring in hole to the other end.At present, the feed arrangement of boring cutter is the knife rest that boring cutter is installed on boring bar, and knife rest rotates with boring bar and can on boring bar, endwisely slip, and has shift fork to be installed on the movable carriage, promotes the knife rest feed again through shift fork during feed.But this shift fork is step when operation, and making feed also is the batch (-type) feed, turns around feed once.Feed arrangement is relatively heavier simultaneously, and volume is bigger, and install adjustment is very loaded down with trivial details.Boring equipment as one of tooling device important in the shipbuilding; Because the equipment body is very big; Make its feed arrangement that will dispose just heavy more huge, adjusting at the scene and operation be difficulty relatively more, so cause the precision of this boring equipment to be difficult to control more easily; Often occur because the production cycle and the quality of bore hole process and quality influence whole piece ship bring bigger loss for shipbuilding enterprise.
Summary of the invention
To above-mentioned deficiency, the utility model be exactly to provide a kind of can be continuously, the steady feed arrangement of the boring cutter of feed.
The feed arrangement of the boring cutter that the utility model provides; Be installed in outside the boring bar to boring cutter knife rest matched in clearance; The screw mandrel that is installed in boring bar one side is abreast arranged, and the boring cutter knife rest is threaded with screw mandrel, and the boring bar end is equipped with feed change; The feed change casing is fixedly connected with the boring equipment frame, between boring bar and the screw mandrel with the planetary gearsets transmission.
The feed arrangement of the boring cutter that the utility model provides is delivered on the screw mandrel by the rotation with boring bar of the feed change of boring bar end, and the rotation of screw mandrel is then moved along the boring bar axis through driving the boring cutter knife rest with being threaded of boring cutter knife rest.Compared with prior art, the utility model is through the continuous feed that drives the realization boring cutter certainly of boring bar, and the relevant stable drive of relative boring, realizes the high accuracy operation.Simultaneously, the utility model also compact conformation is reasonable, and weight is lighter, and transmission is uniform and stable.
Said boring cutter knife rest is installed through carriage saddle, promptly has a carriage saddle to be installed on boring bar and the screw mandrel in addition, and the boring cutter knife rest then is installed on the carriage saddle, so that knife rest is carried out modularized design, is convenient for changing cutter.
The central gear of said planetary gearsets is installed on the feed change casing, and planetary gear is installed on the boring bar end face, and screw mandrel cogs and is connected with planetary gear through change-speed gearing, and change-speed gearing is installed on the boring bar end face.Said planetary gear has a plurality of, and planetary gear also has a plurality of the link with change-speed gearing group between the screw mandrel, and each bar change-speed gearing group chains all has manual clutch, so that when operation, can in a plurality of feed velocitys, select one.
The feed arrangement of the boring cutter that the utility model provides is equipped with the driven by servomotor device between boring bar and the boring equipment frame, and servo motor shaft is connected with a worm screw, and worm gear is that axle is installed with the boring bar; Also can install the rotating speed of gear again additional between servomotor and the worm screw with further adjustment boring bar.With the driven by servomotor boring bar, the rotation that not only makes the boring machine more steadily also and then make feed more steady.
Description of drawings
Fig. 1 is the structure chart of the utility model one embodiment, among the figure: the 1-feed change, the 2-servo drive, 3-holds bracing or strutting arrangement, 4-intermediate supports device; The 5-boring bar, 6-carriage saddle, 7-copper nut, 8-plane knife rest, 9-screw mandrel; The 10-inner conical drogue, 11-external conical sleeve, 12-self-aligning roller bearing, 13-knife rest.
The specific embodiment
In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is done further to detail below, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
The feed arrangement of the utility model boring cutter, its a kind of specific embodiment is as shown in Figure 1.There is boring bar 5 to be installed on the frame (not shown) with intermediate supports device 4, plane knife rest 8 and straight hole boring tool holder are installed on the boring bar active section through end bracing or strutting arrangement 3.Boring bar one side is equipped with a rhizoid bar 9 abreast, and a feed change 1 is respectively installed at the boring bar two ends, and the feed change casing is installed on the frame, and the boring bar section is a circle jaggy in this example, and screw mandrel is mounted in this breach, and feed change then is a round box.The planetary gear transmission shifting mechanism is installed in the feed change of two ends symmetrically.The central gear coaxial with boring bar is installed on each casing; There are three planetary gears and seven travelling gears to be installed in the boring bar end and are connected with the screw mandrel upper transfer gear; Also have four clutch gears to be equipped with on the adjustable shelf; Transmission link through six different speed ratios of the collocation of clutch gear one-tenth capable of being combined promptly can obtain six kinds of different speed ratios through manual adjustment between screw mandrel and boring bar.Servo drive 2 is arranged, and wherein having with the boring bar is the worm gear of axle, and the worm screw that cooperates with worm gear is connected with a servomotor through speed change gear, and this drive unit is installed on the frame.The straight hole boring tool holder comprises carriage saddle 6 and knife rest 13, and carriage saddle is installed with copper nut 7, and copper nut is threaded with screw mandrel, and carriage saddle also is installed on the boring bar with the mode of matched in clearance simultaneously, and knife rest then is installed on the carriage saddle through screw.
