Detailed description of the invention
Be a kind of end face finish-milling fixture being applicable to the gradient engine cylinder cover of band of the present invention as shown in Figure 1, Figure 2, Figure 3 and Figure 4, it comprises the base for placing cylinder cap 15 and establishes the hold-down mechanism for fixing cylinder cap 15 on the base, base comprises one piece of location-plate be obliquely installed 2, cylinder cap 15 is placed on its bottom surface the detent mechanism that location-plate 2 is arranged and positions, detent mechanism is formed with the inclined plane identical with cylinder cap 15 top surface inclination angle, after clamping cylinder cap 15, the end face of cylinder cap 15 and horizontal direction parallel.Compared with prior art, it is consistent with top surface of cylinder cover angle that this top surface of cylinder cover finish-milling fixture has made cylinder cap installation placement location, make cylinder cap 15 after clamping, machine tool horizontal direction still can be kept to process, thus considerably reduce troublesome angle adjustment problem in traditional frock, facilitate the operation clamping of workman, cylinder cap 15 clamping efficiency significantly improves.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, detent mechanism comprises multiple support nail be located on location-plate 2, and on the plane of orientation that the end face that cylinder cap 15 is supported on all support nails is formed, this plane of orientation is the inclined plane identical with cylinder cap 15 top surface inclination angle.Support nail is provided with eight altogether.Support nail is according to the difference of its shape, cylindrical support is divided into follow closely 9 and semicolumn support nail 10, cylindrical support nail 9 has seven, semicolumn support nail 10 is one, wherein six cylindrical support nail 9 point two row's distributions on location-plate 2, remain cylindrical support nail 9 near an end of location-plate 2 and the centre position being positioned at two row's cylindrical support nails 9 arrange, the other end that semicolumn support nail 10 is positioned at location-plate 2 is arranged.This set of support nail can guarantee that cylinder cap 15 is located more accurately with steady.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the angle that location-plate 2 tilts can be identical with cylinder cap 15 top surface inclination angle, on base plate 5, ad-hoc location is provided with three end faces and wants isoplanar to polish with these three floor 3 upper surfaces of floor 3(at the inclination angle identical with cylinder cap 15 top surface inclination angle and form the fixed pan of location-plate 2), namely location-plate 2 is arranged on three floors 3.Location-plate 2 adopts this set, so only need guarantee that support nail and location-plate 2 are installed in vertical state.In order to ensure cylinder cap 15 end face add man-hour position reliable, location is more accurate, two locating holes are side by side processed with on location-plate 2 both sides, and in these two locating holes, two alignment pins are installed, one of them is circular pegs 11, another one is rhombus pin 14, and with this two pin of screw fastening, select in the bottom surface of cylinder cap 15 and have the locating hole suitable with this two alignment pins.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, hold-down mechanism comprises three oil cylinders be located on base, three oil cylinders clamp cylinder cap 15 jointly, three oil cylinders are distributed in the both sides of location-plate 2, are respectively and are positioned at left oil cylinder on the left of location-plate 21 and the right side one oil cylinder 6 be positioned on the right side of location-plate 2 and right two oil cylinders 7.Base is provided with the cushion block for installing oil cylinder, be respectively the left cushion block 4 be positioned on the left of location-plate 2 and the right cushion block 8 be positioned on the right side of location-plate 2, left cushion block 4 and the end face of right cushion block 8 are the inclined plane identical with cylinder cap 15 top surface inclination angle, left oil cylinder 1 is arranged on the end face of left cushion block 4, and a right oil cylinder 6 and right two oil cylinders 7 are arranged on the end face of right cushion block 8.In order to ensure the normal work of oil cylinder, between left oil cylinder 1, a right oil cylinder 6, right two oil cylinders 7, oil inlet pipe 12 and oil exit pipe 13 are installed.
When using this fixture, engine cylinder cover 15 to be processed is placed on the Position with One Plane and Two Holes position of setting on location-plate 2, push down cylinder cap 15 with being arranged on base plate 5 both sides with the oil cylinder on the cushion block of same tilt angle simultaneously, whole like this cylinder cap 15 is just clamped completely on lathe, finally machine and just can carry out finish-milling to this cylinder cap 15 end face and machined, can change in time when support nail wear extent is excessive in multiple clamping.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
