The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention will be further described.
As shown in Figure 1, the press-loading device of a kind of engine cylinder cover seat ring of the present invention, be mainly used in manufacturing experimently in production process by the seat ring interference be press fit on the press mounting hole of engine cylinder cover, comprise the base 2 be fixed on press bench face 1 and be positioned at the pedestal ring indenter 3 that the base top is connected with press ram 4, on base, corresponding workpiece positioning structure can be set, so that making workpiece can locate rapidly and accurately, specifically two conical dowel pins can be set on base, certainly, we need to correspondingly arrange two locating holes on the bottom surface of workpiece.In addition, at pedestal ring indenter, near the end face of base, a columniform seat ring convex neck 31 is set, the external diameter of seat ring convex neck and the internal diameter adaptation of seat ring 9, the while arranges magnet 5 in pedestal ring indenter inside.Like this, when press-fiting, seat ring can be enclosed within from lower to upper on the seat ring convex neck of pedestal ring indenter, and utilize the suction of magnet that seat ring is absorbed and fixed on pedestal ring indenter, when press ram is descending, the seat ring be adsorbed on pedestal ring indenter can be press fit in the press mounting hole 82 of engine cylinder cover exactly.
Certainly, the arrangement of magnet can be as shown in Figure 2 and Figure 3, we first arrange some magnetic hole 32 at the pedestal ring indenter end face, the magnetic hole around seat ring convex neck ringwise decile arrange, magnet is embedded in each magnetic hole, and near an end of pedestal ring indenter end face, magnetic conductor 6 is set at magnet, and the surface of magnetic conductor is lower than the pedestal ring indenter end face, thereby the magnetic force that makes magnet concentrates in magnetic conductor, avoid the counter race pressure head to produce magnetization, and be conducive to strengthen the overall suction of magnet.
Owing between the press-assembling surface of engine cylinder cover and bottom surface, usually having an angle, therefore, the bearing-surface of base need to have corresponding angle of inclination, in order to make the press-assembling surface maintenance level of workpiece.As a kind of prioritization scheme, as shown in Figure 1, base 2 comprises the base plate 21 that is connected with press bench face 1, is removably disposed on base plate and the taper liner plate 22 that upper surface tilts and the location panel 23 that is removably disposed in taper liner plate upper surface, thereby the upper surface that makes location panel has certain gradient, in order to make the press-assembling surface 81 maintenance levels of workpiece, by changing different taper liner plates, can make base adapt to dissimilar workpiece, in order to make the press-assembling surface of workpiece remain at level.Be understandable that, can be arranged on the upper surface of location panel in order to the conical dowel pin of positioning workpieces, and between base plate and taper liner plate and between taper liner plate and location panel, all can adopt screw to connect.
For the ease of the adjustment at location panel angle of inclination, above-mentioned prioritization scheme also can adopt following scheme to substitute:
As shown in Figure 4, base 2 comprises the base plate 21 that is connected with press bench face 1, is inclined at the location panel 23 on base plate, a side and base that location panel is lower are rotationally connected, simultaneously, the side lower surface that location panel is higher is hinged with connecting rod 25, the other end of upper connecting rod is hinged with lower link 26, the other end of lower link is hinged on base plate, and the hinged length-adjustable support bar 24 at upper and lower rod hinge connection place, the other end of support bar is hinged on base plate, thereby makes upper and lower connecting rod and support bar form Y-shaped structure.Support bar comprises connecting rod 241 and the middle coaxial adjusting rod 242 of both sides, and adjusting rod is and is threaded with the connecting rod of both sides, and the rotation direction of both sides screw thread is contrary.And we also need arrange two parallel planes on middle adjusting rod, in order to clamp two planes with rotary regulating lever by spanner, the connecting rod that makes both sides mutually near or be separated from each other, thereby change the length of support bar, to change the angle between upper and lower connecting rod, and then the angle of inclination of adjustment location panel.Be understandable that, the conical dowel pin of positioning workpieces can be arranged on the upper surface of location panel.It should be noted that, the Y shape supporting construction consisted of upper and lower connecting rod and support bar can arrange two covers abreast, to improve the stability supported.Further, as shown in Figure 5, also two cover supporting constructions can be shared to a support bar, specifically can between the upper and lower connecting rod hinge point of two cover supporting constructions, by a gangbar 27, connect, the two ends of this gangbar are provided with rotating shaft, the upper and lower connecting rods of two cover supporting constructions are set in respectively in the rotating shaft at gangbar two ends rotationally, and an end of support bar is rotatably connected on the position, middle of gangbar, make the gangbar can be at the rotation with in surface of crossing gangbar axis and support bar axis.Like this, when the length of support bar is elongated, can make the angle between the upper and lower connecting rod of both sides become large by gangbar, thereby increase the angle of inclination of location panel, because gangbar can be at the rotation with in surface of crossing gangbar axis and support bar axis, and they sup-port, in the position, middle of gangbar, therefore can be guaranteed that support bar has identical support force to the supporting construction of gangbar both sides, thereby guarantee the stress equalization of location panel.Certainly, we also can arrange a breach on base plate, and the end that lower connection is connected with base plate with support bar is positioned at this breach, make location panel can be adjusted to horizontal level.
As Fig. 1, shown in Fig. 4, for the workpiece to inclined bottom surface provides better support in press-fiting process, we also can be lower at the location panel upper surface a side at least one workpiece mechanism 7 is set, this workpiece mechanism comprises the fixed block 71 that is fixed on the location panel upper surface, be positioned at the fixed block side and be slidably connected at the sliding shoe 72 of location panel upper surface, and be located at the up big and down small latch segment 73 of splitting shape that is between fixed block and sliding shoe, can form and be slidably connected by structures such as T-slot or dovetail grooves between sliding shoe and location panel, in order to sliding shoe can not separated with location panel, the glide direction of sliding shoe should be consistent with the incline direction of location panel, split the lateral vertical of the latch segment of shape and fixed block laminating in the location panel upper surface, fit in the inclined-plane corresponding with sliding shoe, opposite side inclined-plane relative on latch segment, another side away from latch segment on sliding shoe is the confined planes of fitting with the edge of workpiece, and leave gap between the bottom surface of latch segment and location panel upper surface, like this, when latch segment moves down, can produce a horizontal push effect to sliding shoe, the confined planes that makes sliding shoe near and be close to the edge of workpiece, in order to workpiece is produced to position-limiting action.Be understandable that, as shown in Fig. 6, Fig. 7, Fig. 8, we can arrange the bolt through-hole 731 perpendicular to location panel on latch segment, one adjusting bolt 74 is connected to the location panel surface through the bolt through-hole rear thread, and adjusting bolt sheathed back-moving spring 75 between latch segment and location panel.Like this, the forward rotation adjusting bolt can press down latch segment like a cork, and rotate backward adjusting bolt, can utilize the elastic force of back-moving spring that latch segment is lifted to reset, now can move sliding shoe by manual mode, thereby make confined planes on sliding shoe leave the edge of workpiece, to facilitate the dismounting of workpiece.
Further, as shown in Fig. 6, Fig. 8, the first rib 721 of evagination is set in the left and right sides, inclined-plane of sliding shoe and latch segment laminating, thereby sliding shoe and latch segment are fitted, a side forms and the U-shaped chute of latch segment adaptation, at the first rib and the latch segment joint place junction of the edges of two sheets of paper, cylindrical hole 76 is set, the axis of cylindrical hole is parallel with the inclined-plane of sliding shoe, lead 77 is set in cylindrical hole, and between lead and sliding shoe, holding screw 78 is set the junction of the edges of two sheets of paper simultaneously; Similarly, the second rib 711 of evagination is set in the left and right sides, side of fixed block and latch segment laminating, thereby fixed block and latch segment are fitted, a side forms and the U-shaped chute of latch segment adaptation, at the second rib and the latch segment joint place junction of the edges of two sheets of paper, cylindrical hole is set, the axis of cylindrical hole is perpendicular to the location panel upper surface, lead is set in cylindrical hole, and between lead and fixed block, holding screw is set the junction of the edges of two sheets of paper simultaneously.Lead is fixed on sliding shoe and fixed block by holding screw, to form guide rail structure, latch segment can be slided up and down along the lead of fixed block both sides.Rise under the effect of latch segment at back-moving spring while resetting, can drive sliding shoe to fixed block one side shifting, to remove spacing to workpiece, thereby form linkage structure.Because cylindrical hole can machine by simple drilling, lead is assembly and disassembly easily, thereby makes manufacture and safeguard more convenient.
In addition, as shown in Figure 1, Figure 3, we arrange coaxial guide pillar 33 at also can the be present end face of circle convex neck, and the tapering of 5-8 degree is set in the end of guide pillar, and the diameter of guide pillar should cover guide hole 83 adaptations coaxial with the seat ring press mounting hole with engine cylinder.Like this, the guide pillar that coaxially is arranged on convex neck end face can enter in advance in the guide hole adaptive with it when press-fiting, thereby plays the guide-localization effect, further to mention the relative positional accuracy between hole that is pressed into of seat ring and workpiece.
Guide effect between the guide hole covered in order to ensure guide pillar and the engine cylinder of seat ring convex neck end face, as Fig. 9, shown in Figure 10, we can be connected by Connection Block 10 pedestal ring indenter with press ram 4, and in the lower surface of Connection Block, circular cavity 11 is set, the madial wall of cavity along the circumferential direction compartment of terrain etc. minute arranges the locating hole 13 of three chutes 12 and three circles, chute and locating hole radially run through lateral wall along cavity, chute has the upper side wall of a level and the lower wall of a level, and the upper end of pedestal ring indenter is cylindrical, the upper end of pedestal ring indenter is positioned at cavity, and and leave gap between cavity, the position of corresponding three chutes of upper end lateral wall of pedestal ring indenter is respectively equipped with slide bar 34 radially, slide bar extend in chute slidably, and there is gap between the left and right sides of slide bar and chute, thereby pedestal ring indenter is suspended in the cavity of Connection Block slidably, set gradually outward alignment pin 14 from the cavity inboard in locating hole, spring 15 and adjustment screw 16, the end of alignment pin is stretched out locating hole and is resisted against on the lateral wall of pedestal ring indenter.By rotating the adjustment screw pressure of regulating spring to alignment pin easily, thereby flexibly being floated, pedestal ring indenter is positioned at the centre position of cavity.While press-fiting, if because the trueness error of workpiece causes coaxiality deviation between the press mounting hole of pedestal ring indenter and workpiece, the guide pillar that is arranged on convex neck end face still can rely on the tapering of its end first to be advanced in guide hole, now guide hole produces the push effect of a horizontal direction to guide pillar, therefore pedestal ring indenter can overcome the elastic force of spring and automatically adjust its position, thus the axiality between the press mounting hole of seat ring and workpiece while guaranteeing to press-fit.
