Description

Be used to process the Ni Zhifu drill of valve

Technical field

The utility model relates to a kind of drilling machine, especially a kind of drilling equipment of many drill bits.

Background technology

In the valve processing, often need are evenly processed several holes to the same end face of several workpiece of same size, as process through hole on former and later two end faces of valve main valve body, the processing method that the workman adopts usually is that workpiece is fixed on the radial drilling machine commonly used, after finishing the position line in each hole, luxuriant boring one by one, after the institute on what a end face of processing is porose, unclamp anchor clamps again, the another side that changes workpiece clamps and carries out the boring of setting-out one by one processing again, after processing what a workpiece, process another workpiece more successively.This processing method is for the workpiece of the fixedly specification of batch machining, its production efficiency is low, because, the position line of at first determining each hole just needs for a long time, sometimes need to determine as calculated the particular location in each hole, processing a workpiece often needs the process that repeatedly repeats to clamp, process, unclamp, and will repeat the identical course of work for different workpiece.For equipment investment, the equipment input cost of radial drilling machine is big simultaneously, and therefore the shortcoming of traditional processing method is: production efficiency is low, equipment input cost height.

Summary of the invention

The purpose of this utility model just provides the Ni Zhifu drill that a kind of production efficiency height, low being used to of equipment input cost are processed valve.

By a kind of Ni Zhifu drill that is used to process valve that the utility model proposes, comprise frame and the Ni Zhifu drill device that is connected on the frame, the Ni Zhifu drill device is by making the lathe bed of feed motion with respect to frame and being fixed on drive unit on the lathe bed, some brills and transmission device constitute, drive unit connects the brill rotation that drives on the Ni Zhifu drill head with transmission device, on frame, be arranged with two Ni Zhifu drill devices, the transmission device of every Ni Zhifu drill device comprises power transmission shaft, master gear and several and master gear mesh from gear, the rear end of each brill be provided with from the brill gear of gears engaged, master gear is fixed on the power transmission shaft, is rotatably connected on the support that is connected with lathe bed from gear and brill.

Adopt said structure, when to Workpiece boring, workpiece is fixed on the centre position of two Ni Zhifu drills on the frame, open drive unit, power transmission shaft rotates from gear with moving several of forward (FWD) simultaneously by master gear, drive brill from gear again by gears engaged and rotate, by the lathe bed feeding whole device is moved to workpiece gradually again, can once bore whole through holes of end face simultaneously with drill rear end.

When making each bit bore, can carry out simultaneously, described brill comprises drill bit and drill bushing, drill sleeve is contained in the drill bushing, brill is provided with and bores the length adjusting device, and it comprises gear and rotating bolt, and gear and bolt are affixed, the rear end of drill bit is provided with tooth bar, the adaptive formation rack and pinion drive mechanism of wheel and rack.When need are regulated the length of boring, rotating bolt, the gear drive tooth bar moves forward and backward, and can realize boring the adjusting of length.

In sum, because the utility model is in when boring, the institute of two end faces of valve is porose once can all to be drilled to, and workpiece is in when boring, not repeated disassembled and assembled anchor clamps, so the utility model working (machining) efficiency height, the utility model is simple in structure simultaneously, so the equipment input cost is low.

The specific embodiment

Below in conjunction with description of drawings the utility model is described in further detail.

The utility model as shown in Figure 1, it comprises frame 16 and is connected in two Ni Zhifu drill devices of symmetric arrangement on the frame 16, every Ni Zhifu drill device constitutes by making the lathe bed 1 of feed motion with respect to frame 16 and be fixed on the drive unit on the lathe bed 1, some brills and transmission device, and drive unit connects the brill rotation that drives on the Ni Zhifu drill device with transmission device.

Drive unit as shown in Figure 1, it comprises motor 2.

Transmission device as shown in Figure 3, Figure 4, it comprises power transmission shaft 4, master gear 11 and some from gear 9, affixed from gear 9 and turning cylinder 8, turning cylinder 8 two ends are connected on the support 20 by bearing.Master gear 11 is fixed on the power transmission shaft 4, and from gears engaged, drill bushing 10 is fixed in the bearing 18 with respectively, and bearing 18 is fixed in the bearing block 17, and bearing block 17 is fixed on the support 20, and an end of brill 5 is connected with and bores gear 12, from gear 9 and 12 engagements of brill gear.

Bore 5 and constitute, bore the length adjusting device boring also to be provided with on 5 by drill bushing 10 and drill bit 7 two parts.Drill bit 7 is sleeved in the drill bushing 10, and it comprises gear 15 and rotating bolt 13 to bore the length adjusting device, and gear 15 is affixed with bolt 13, and the rear end of drill bit 7 is provided with tooth bar 14, gear 15 and tooth bar 14 adaptive formation rack and pinion drive mechanisms.

Motor 2 connects by shaft coupling 3 with power transmission shaft 4.
