The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
Like Fig. 2; Hydraulic cylinder is made up of front end housing 1a, piston rod 1b, cylinder barrel 1c, piston 1d, back cylinder cover 1e etc.; Sliding bearing (not expression in the accompanying drawing) is housed between cylinder cap and the piston rod; The end that piston rod is positioned at front end housing 1a is used to connect the gusset piece of drilling machine, makes collar bush press moving and moving of piston rod, and the end that piston rod is positioned at back cylinder cover 1e is used to eliminate the condition of self-locking because of the frictional force generation with the other end.
Referring to Fig. 1, the drilling machine feed that the utility model proposes includes head box 2, on head box 2, is provided with the spline housing 6 and the belt drive unit 7 that drive main shaft 3 rotations with hydraulic cylinder and automatic feeder, also comprises the mechanism of the feed of control main shaft, withdrawing; Hydraulic cylinder 1 is housed in the head box 2, and the piston rod 1b of hydraulic cylinder 1 is connected as a single entity through gusset piece 5 and collar bush 4, and the keeping parallelism of piston rod 1b and collar bush 4 axis; Referring to Fig. 3, in hydraulic circuit, insert the unidirectional flow speed control valve 12 of KFC type, be installed in the head box right side, the speed in the time of can adjusting main shaft cutting feed through the speed governing knob 12a on the unidirectional flow speed control valve 12; Speed control rod 14 is arranged on gusset piece, speed governing piece 15 is housed on the speed control rod 14, reach speed governing and stir post 15a, be used for secondary speed control is carried out in the main shaft feed; As shown in Figure 5, on gusset piece, also have depthkeeping bar 17, down stroke briquetting 18 is arranged, up stroke briquetting 19 on the bar; The left side of head box 2 is equipped with electric control box 20.
The mechanism of control feed velocity is that post 15a etc. is stirred in the unidirectional flow speed control valve of hydraulic cylinder 1, KFC type 12, speed control rod 14, speed governing piece 15 and speed governing, and wherein speed governing knob 12a is used to adjust drill bit carries out drilling to workpiece feed velocity.Through the drive of piston rod 1b, gusset piece 5 and speed control rod 14, be fixed on speed governing on the speed governing piece 15 and stir post 15a and move down, stir the speed-varying rotor 12b on the unidirectional flow speed control valve 12 of KFC type, make feed velocity produce the secondary speed change.Before stirring post 15a and not stirring speed-varying rotor 12b, feed velocity is the feed velocity without speed governing; After stirring post 15a and stirring speed-varying rotor 12b, feed velocity is through the adjusted drilling feed velocity of speed governing knob 12a.
The structure of control main shaft depth of cut is the lower stroke switch 13 that is contained in head box 2 right sides, upper stroke switch 16, with together depthkeeping bar 17 of collar bush 3 and gusset piece 4, be installed in down stroke briquetting 18 and up stroke briquetting 19 etc. on the depthkeeping bar 17.When the up stroke briquetting 19 on the depthkeeping bar 17 was pressed onto upper stroke switch 16, hydraulic cylinder stopped to move back and draws, and this moment, main shaft 3 was in the original position of stroke; When the down stroke briquetting 18 on the depthkeeping bar 17 was pressed onto lower stroke switch 13, hydraulic cylinder 1 stopped to advance, and this moment, main shaft was in the final position of stroke.Down stroke briquetting 18 is fixed on the depthkeeping bar 17 through holding screw, through the position of adjustment down stroke briquetting 18 on depthkeeping bar 17, just can control the stroke of main shaft 3, thereby realize the control of drilling depth.
During work, workbench (not representing locking mechanism among the figure) must be locked after adjusting to the right place, so that the drill bit that is fastened in the spindle taper hole can carry out Drilling Operations (not representing drill bit and workpiece among the figure) to workpiece in the position of adjustment workbench 10 on column 9 earlier; Energized makes oil supply system 11 work then; On the guidance panel of electric control box 20, confirm the drilling machine feed mode on demand: manual control main shaft feed withdrawing is arranged, control main shaft feed withdrawing and control main shaft automatically and repeat the feed withdrawing automatically; Restart motor 8, motor 8 drives main shaft 3 rotations through belt drive unit 7 and spline housing 6; The corresponding button on the push panel, the piston rod 1b of hydraulic cylinder 1 advances gusset piece 5 downwards, drives collar bush 4, main shaft 3 feeds fast downwards, when stir post 15a dial change fast rotor 12b after, the main shaft feed promptly can be changed into the drilling feed, drill bit is holed.After down stroke briquetting 18 was pressed onto lower stroke switch 13, hydraulic cylinder 1 was become to move back fast by the drilling feed and draws, and got back to the stroke original position fast thereby drive main shaft, in the process that main shaft returns, stirs post 15a speed-varying rotor 12b is dialled original state of getting back to.
Like Fig. 6; When work, can select through the cycle knob 20a on electric control box 20 panels is single cycle or repetitive cycling, confirms still work automatically of manual operation through pattern knob 20b; After boring reaches and confirms the degree of depth; In this locational time of staying, in the stand-by period of its start of a run, have sufficient time to workpiece loading and unloading through knob 20c adjustment drill bit with assurance through knob 20d adjustment drill bit.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
