Detailed description of the invention
Be described further below in conjunction with accompanying drawing 1 to accompanying drawing 7 pairs of the utility model.
With a cushioning supportive frame for micro-adjusting mechanism, comprising: fixed support 1, its both sides, lower end horizontally rotate the spacing be provided with between wheelspan between some roller 21, two side wheels 21 and the guide rail of numerical control drilling machine lathe bed both sides respectively and match; Roller bracket 7, it is arranged at above fixed support 1, and drives its relative fixed support 1 to move up and down by elevating mechanism; V-type support 6, be in the shape of the letter V structure, and it is vertically slided by carriage and is arranged on roller bracket 7; And draw-gear, it is arranged on fixed support 1, is walked by the guide rail of walking mechanism along numerical control drilling machine lathe bed both sides for fixed support 1; V-type support 6 is rotatablely equipped with the backing roll 23 of some arrangements that is in the shape of the letter V, on roller bracket 7 be arranged at the backing plate 23 that be in the shape of the letter V corresponding with backing roll 23, V-type support 6 and roller bracket 7 are provided with micro-adjusting mechanism, and micro-adjusting mechanism drives the upper surface of upper roll surface below or above backing plate 22 of each backing roll 23.The cushioning supportive frame of this band micro-adjusting mechanism is made to run to correct position by roller 21 along guide rail by draw-gear during use.To the work piece hoisting of processing be needed on roller bracket 7 afterwards, workpiece contacts with backing plate 22, supports workpiece by the backing plate 22 of V-arrangement, and it supports the good stability of fixation workpiece.The index chuck of numerical control drilling machine blocks the end of workpiece afterwards, and on lathe, workpiece detects in testing agency.Lathe starts to carry out Drilling operation to workpiece afterwards, until the hole on same bus all processes, micro-adjusting mechanism driving V-shaped support 6 moves up, make the upper surface of upper roll surface higher than backing plate 22 of backing roll 23, now workpiece is by backing roll 23 jack-up, and the index chuck on numerical control drilling machine drives workpiece to rotate, workpiece realizes rotating on backing roll 23, frictional force is little, and numerical control drilling machine carries out Drilling operation on another bus of workpiece, until the hole on same bus all processes.Micro-adjusting mechanism counteragent, driving V-shaped support 6 moves down, and the backing roll 23 on V-type support 6 is separated from workpiece, and workpiece is supported by backing plate 22 again.
As shown in Figure 1, further can also comprise the WidFin oil cylinder 13 that horizontal slip is installed on the slide 8 on fixed support 1 and is fixed on fixed support 1, the piston rod head end of WidFin oil cylinder 13 is connected to slide 8, and roller bracket 7 is fixed on slide 8.Fine setting oil cylinder 13 drives slide 8 fixed support 1 transverse shifting relatively, thus the object that the cushioning supportive frame that can realize this band micro-adjusting mechanism is laterally finely tuned, workpiece centering can be guaranteed.Roller bracket 7 lower end is vertically fixed with some guide pillars 4, and on slide 8, correspondence is provided with some guide pin bushings 5, and guide pillar 4 slides and is plugged in guide pin bushing 5.By arranging guide pillar 4 and guide pin bushing 5, roller bracket 7 can be made more steady in the process of lifting.Elevating mechanism can be following structure, and it comprises the hoist cylinder 11 be vertically installed on slide 8, the piston rod head end of hoist cylinder 11 and roller bracket 7.The piston rod of hoist cylinder 11 is protruding, and promote roller bracket 7 and move up, the piston rod of hoist cylinder 7, to bouncing back back, namely pulls roller bracket 7 to move down, thus convenient whole according to the center height of workpiece.
As shown in Figure 1, draw-gear is the adapter sleeve 9 being arranged at fixed support 1 both sides respectively, and the guide rod that stretches out on the endoporus of adapter sleeve 9 and numerical control drilling machine gantry matches.Therefore be inserted in adapter sleeve 9 to play driven the clamp system of this tubing with the object of gantry action by the guide-bar mechanism that stretches out be arranged on numerical control drilling machine gantry, structure is simple, uses reliable.
As shown in Figure 4, carriage can be following structure, it comprise vertically be installed on roller bracket 7 both sides and in the guide plate 17 of U-shaped and correspondence be installed on the self-lubricating plate 18 of V-type support 6 both sides, self-lubricating plate 18 slides and is plugged in the U-lag of guide plate 17.Self-lubricating plate 18 resistance to sliding in guide plate 17 is little, not easy to wear, improves service life and dependability.As shown in Figure 5, micro-adjusting mechanism can for being vertically fixed on the fine setting oil cylinder 14 on roller bracket 7, and the piston rod head end of fine setting oil cylinder 14 is connected with V-type support 6, moved up and down by fine setting oil cylinder 14 driving V-shaped support 6 opposed roller wheel support 7, structure is simple, reliable.
Further, as shown in Figure 2, fixed support 1 bottom level is provided with clamping cylinder 20, after the guide rail walking of the relative numerical control drilling machine of cushioning supportive frame of this band micro-adjusting mechanism puts in place, the piston rod of clamping cylinder 20 stretches out, and its piston rod head end contacts with guide rail lateral margin.Effectively can prevent from that the situation causing affecting crudy occurs to offset in the whole process of processing work to occur.Fixed support 1 both sides are respectively arranged with scrapes bits plate 19, and the upper rail level scraping corresponding with this side respectively guide rail in lower end of bits plate 19 contacts with guide rail side.Scrape bits plate 19 iron filings on guide rail to be struck off, preventing iron filings from entering in locking cylinder affects braking effect and prevents disfiguring workpiece.
As shown in Figure 5, bottom fixed support 1, side is provided with cam guide 10, and its opposite side is provided with eccentric cam guider 12, cam guide 10 and corresponding with this side respectively guide rail lateral margin Structure deformation of eccentric cam guider 12.By adjusting the degree of eccentricity of eccentric cam 12, cam guide 10 and eccentric cam guider 12 are contacted with guide rail lateral margin respectively, thus play the effect preventing the cushioning supportive frame of this band micro-adjusting mechanism from skew not occurring in the process of walking.
As shown in Figure 4, fixed support 1 is provided with some outwardly bumper frame 15 near numerical control drilling machine side, be provided with bumper 16 outside bumper frame 15.Bumper 16 can prevent other work mounting s mechanisms on the cushioning supportive frame of this band micro-adjusting mechanism and numerical control drilling machine from rigid collision occurring, and causes the situation of disfiguring workpiece to occur.As shown in Figure 1, slide 8 can vertically be fixed with scale 2, roller bracket 7 be provided with the pointer 3 pointing to scale 2 scale.Scale 2 and pointer 3 coordinate to indicate current V-type support 6 place height and position, carry out fast and easy adjustment in order to the workpiece for different-diameter specification.
