Horizontal boring machine
Technical field
The utility model relates to field of machining, the horizontal boring machine simple in structure on especially a kind of weldering drill jig that is fixed on automobile frame band rig.
Background technology
The vehicle frame manufacturing of automobile needs welding forming, and wherein must hole with horizontal drilling machine behind welding fabrication in the hole on some punch forming part; Chinese patent application number: 200720069392.2 utility model discloses a kind of horizontal drilling machine, and this horizontal drilling machine comprises bench drill, and bench drill is connected with support with connecting plate, and support is a H shape cross bar of being with feet; Connecting plate is welded on the end of support and has the slotted hole that connects bench drill, is provided with V-arrangement anchor clamps and workpiece holder on support, and bench drill is connected with connecting plate with bolt and nut, and the V-arrangement anchor clamps are connected with support with bolt with workpiece holder; This horizontal drilling machine is according to the processing needs, and the lengthwise position of drilling machine can be regulated, and has enlarged the range of work; Its weak point is: this horizontal drilling machine volume is bigger, and structure is complicated; The boring processing that is used for behind the vehicle frame welding fabrication is not suitable for; Therefore little, the simple in structure horizontal boring machine that designs a kind of volume to the processing of holing of the vehicle frame behind the welding fabrication, becomes problem demanding prompt solution.
The utility model content,
The purpose of this utility model is bigger in order to overcome existing horizontal drilling machine volume, and structure is complicated; Be used for the unaccommodated deficiency of vehicle frame boring processing behind the welding fabrication, provide a kind of and be fit to the processing of holing of the vehicle frame behind the welding fabrication, volume is little, horizontal boring machine simple in structure.
Concrete technical scheme of the present utility model is:
A kind of horizontal boring machine, described horizontal boring machine comprise horizontal base, horizontal base plate, are provided with guide rail, feed mechanism between described horizontal base, horizontal base plate; Described feed mechanism is cylinder (7); Described horizontal boring machine also comprises motor, shaft coupling, reduction box, bushing plate, drill bit; Described motor is connected with reduction box by shaft coupling; Described drill bit passes bushing plate and is connected with reduction box; Described motor is fixedlyed connected with horizontal base plate; Described reduction box is fixedlyed connected with horizontal base plate; Described bushing plate is fixedlyed connected with horizontal base.Replace horizontal drilling machine with the horizontal boring machine special plane, volume is little, and is simple in structure; As feed mechanism, make centripetal force adjustable and feeding is steady with cylinder, withdraw from fast after the processing; Have bushing plate, can improve borehole accuracy.
As preferably, described bushing plate is provided with drill bushing, and described drill bushing and drill bit are adaptive.Bushing plate is provided with drill bushing, and is not easy to wear, the service life of having improved bushing plate, and convenient maintenance and replacement.
As preferably, described reduction box is a gear reduction box.Gear reduction box is simple and reliable, and according to the boring needs, adorns a plurality of drill bits and be easier to.
As preferably, described guide rail is a line slideway.Line slideway precision height, stable working.
The beneficial effects of the utility model are:
Replace horizontal drilling machine to replace common horizontal drilling machine with the horizontal boring machine special plane, volume is little, and is simple in structure; Have bushing plate, can improve borehole accuracy; As feed mechanism, make centripetal force adjustable and feeding is steady with cylinder, withdraw from fast after the processing.Bushing plate is provided with drill bushing, and is not easy to wear, the service life of having improved bushing plate, and convenient maintenance and replacement.Gear reduction box is simple and reliable, and according to the boring needs, adorns a plurality of drill bits and be easier to.Line slideway precision height, stable working.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure: horizontal base-1, horizontal base plate-2, motor-3, shaft coupling-4, bushing plate-5, drill bit-6, cylinder-7, drill bushing-8, gear reduction box-9, line slideway-10.
The specific embodiment
Below in conjunction with shown in the accompanying drawing the utility model is described further
As shown in Figure 1: a kind of horizontal boring machine comprises horizontal base 1, horizontal base plate 2, line slideway 10; Line slideway is connected with horizontal base, horizontal bottom plate screw respectively; The cylinder body of cylinder 7 is connected with horizontal base screw, and expansion link is connected with horizontal base thread; Described horizontal boring machine also comprises motor 3, shaft coupling 4, gear reduction box 9, bushing plate 5, drill bit 6; Motor is connected with gear reduction box by shaft coupling; Bushing plate is provided with drill bushing 8, and drill bushing and drill bit are adaptive; Drill bit has two, and drill bit passes drill bushing and is connected with gear reduction box; Motor is connected with horizontal bottom plate screw; Gear reduction box is connected with horizontal bottom plate screw; Described bushing plate is fixedlyed connected with horizontal base.
Replace horizontal drilling machine to replace common horizontal drilling machine with the horizontal boring machine special plane, volume is little, and is simple in structure; Have bushing plate, can improve borehole accuracy; As feed mechanism, make centripetal force adjustable and feeding is steady with cylinder, withdraw from fast after the processing.Bushing plate is provided with drill bushing, and is not easy to wear, the service life of having improved bushing plate, and convenient maintenance and replacement.Gear reduction box is simple and reliable, and according to the boring needs, adorns a plurality of drill bits and be easier to.Line slideway precision height, stable working.
