The utility model relates to a kind of puncher, particularly relate to a kind of can simultaneously to the puncher that the cylinders such as the nozzle in multiple TOP-TIP are processed.
In TOP-TIP, picture nozzle, sleeve is modal cylinder-like part, need to carry out a large amount of drilling operations in process, present perforation processing is carried out usually on horizontal drilling machine, because existing horizontal drilling machine only has a driving floral disc and a tailstock, a part can only be processed at every turn, cause operating efficiency lower.Meanwhile, for the hole machined that some are darker, because drill bit is longer, easily eccentric.
Utility model content
For overcoming above-mentioned defect, the utility model aims to provide one and can greatly increase work efficiency, and can ensure again the bull puncher of crudy simultaneously.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bull puncher, comprise lathe bed, one end of described lathe bed is provided with power cabinet, described power cabinet upper driving is connected with multiple chuck, described lathe bed is provided with two guide rails, described slide on rails is connected with a drill headstock, described drill headstock is in transmission connection by a rhizoid bar and a driving machine, described drill headstock is provided with and chuck hub multiple drill bit frame one to one, and described drill bit frame is connected to a drill bit on the direction of chuck.
Be provided with one piece of guide plate between described chuck and drill headstock, described guide plate is provided with the pilot hole that several and drill bit frame position match, and the diameter of described pilot hole and drill bit matches.
Have employed bull puncher of the present utility model, by arranging multiple chuck and drill bit, bore operation can be carried out to multiple sleeve simultaneously, the operating efficiency greatly improved, meanwhile, by arranging guide plate, making drill bit pass pilot hole and holing again, improve the rigidity of drill bit, ensure that crudy.

Detailed description of the invention
As shown in Figure 1, the utility model discloses a kind of bull puncher, comprise lathe bed 1, one end of described lathe bed 1 is provided with power cabinet 2, and bull puncher of the present utility model can use repacking of ordinary lathe, retain lathe bed 1 and the power cabinet 2 of lathe, its innovative point is mainly that described power cabinet 2 upper driving is connected with multiple chuck 3, and each chuck 3 is in transmission connection with lathe mair motor respectively by belt by repacking, under normal circumstances, the quantity of described chuck 3 is set to 2; Described lathe bed 1 is provided with two guide rails 4, described guide rail 4 slidably connects a drill headstock 5, described guide rail 4 can adopt lathe originally all, also can arrange in addition, described drill headstock 5 is in transmission connection by a rhizoid bar 7 and a driving machine 8, described drill headstock 5 is provided with and chuck 3 center multiple drill bit frame 6 one to one, and described drill bit frame 6 is connected to a drill bit 9 on the direction of chuck 3.The center of the chuck 3 that described drill bit 9 is corresponding with it on the same axis.
During specific works, needing the piece-holder of punching on chuck 3, turn on the power cabinet 2, makes chuck 3 drive Work piece high-speed to rotate, simultaneously, open driving machine 8, driving machine 8 is rotated forward, by the conduction of screw mandrel 7, drives drill headstock 5 to move to chuck 3 direction along guide rail 4, when drill bit 9 touches workpiece, drill headstock 5 continues to move along guide rail 4 to chuck 3 direction, carries out drilling operation; When punching is after set depth, driving machine 8 is rotated backward, cross the conduction of screw mandrel 7, drill headstock 5 is driven to move along guide rail 4 towards away from chuck 3 direction, make drill bit 9 leave workpiece, close down power cabinet 2, chuck 3 is stopped operating, then workpiece is pulled down from chuck 3, namely complete the perforation processing to workpiece.The perforation processing while of owing to once can carry out multiple workpiece, makes production efficiency increase at double.
When processing darker hole, in order to improve the rigidity of drill bit 9, another innovative point of bull puncher of the present utility model is to be provided with one piece of guide plate 10 between described chuck 3 and drill headstock 5, described guide plate 10 is provided with the pilot hole 11 that several and drill bit frame 6 position match, and described pilot hole 11 matches with the diameter of drill bit 9.The diameter of usual pilot hole 11 is more bigger than the diameter of drill bit 9, be exactly that drill bit 9 can smoothly by pilot hole 11 specifically, pilot hole 11 again can about fast drill bit 9 rocking in radial direction simultaneously, like this, when carrying out deep hole machining, crudy can not be affected because the radial direction of drill bit is rocked.
