Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, 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 trial-production production process, seat ring being press fit on the press mounting hole of engine cylinder cover with interference, comprise the base 2 that is fixed on press bench face 1 and be positioned at the pedestal ring indenter 3 be connected with press ram 4 above base, base can arrange corresponding workpiece positioning structure, to make workpiece locate rapidly and accurately, specifically two conical dowel pins can be set on base, certainly, we need on the bottom surface of workpiece, correspondingly arrange two locating holes.In addition, arrange a columniform seat ring convex neck 31 at pedestal ring indenter near the end face of base, the external diameter of seat ring convex neck and the internal diameter adaptation of seat ring 9, arrange magnet 5 in pedestal ring indenter inside simultaneously.Like this, seat ring can be enclosed within from lower to upper on the seat ring convex neck of pedestal ring indenter when press-fiting, and utilize the suction of magnet to be absorbed and fixed on pedestal ring indenter by seat ring, 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 holes 32 at pedestal ring indenter end face, magnetic hole is around seat ring convex neck decile layout ringwise, and magnet is then embedded in each magnetic hole, and arranges magnetic conductor 6 at magnet near one end of pedestal ring indenter end face, and the surface of magnetic conductor is lower than pedestal ring indenter end face, thus make the magnetic force of magnet concentrate in magnetic conductor, avoid counter race pressure head to produce magnetization, and be conducive to strengthening the overall suction of magnet.
Owing to usually having an angle between the press-assembling surface of engine cylinder cover and bottom surface, therefore, the bearing-surface of base needs to have corresponding angle of inclination, to make the press-assembling surface maintenance level of workpiece.As a kind of prioritization scheme, as shown in Figure 1, base 2 comprise be connected with press bench face 1 base plate 21, be removably disposed on base plate and the taper liner plate 22 that tilts of upper surface and the location panel 23 that is removably disposed in taper liner plate upper surface, thus make the upper surface of location panel have certain gradient, to make the press-assembling surface 81 maintenance level of workpiece, by changing different taper liner plates, base can be made to adapt to dissimilar workpiece, to make the press-assembling surface of workpiece remain at level.Be understandable that, the conical dowel pin in order to positioning workpieces can be arranged on the upper surface of location panel, and screw all can be adopted to connect between base plate and taper liner plate and between taper liner plate and location panel.
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 be connected with press bench face 1, the location panel 23 be inclined on base plate, the side that location panel is lower and base 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 a 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, thus makes upper and lower connecting rod and support bar form Y-shaped structure.Support bar then comprises the connecting rod 241 of both sides and the adjusting rod 242 of intermediate coaxial, and adjusting rod is with the connecting rod of both sides and is threaded, and the rotation direction of both sides screw thread is contrary.And we also need arrange two parallel planes on the adjusting rod of centre, to clamp two planes with rotary regulating lever by spanner, make the connecting rod of both sides close to each other or be separated from each other, thus 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 be made up of upper and lower connecting rod and support bar can arrange two covers abreast, to improve the stability of support.Further, as shown in Figure 5, also two cover supporting constructions can be shared a support bar, specifically can connect by a gangbar 27 between the upper and lower connecting rod hinge point of two cover supporting constructions, 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 the rotating shaft at gangbar two ends respectively rotationally, and one end of support bar is then rotatably connected on the position, middle of gangbar, make gangbar can at the rotation with in surface crossing gangbar axis and support bar axis.Like this, when the length of support bar, make the angle between the upper and lower connecting rod of both sides become large by gangbar, thus increase the angle of inclination of location panel, because gangbar can at the rotation with in surface crossing gangbar axis and support bar axis, and they sup-port is in the position, middle of gangbar, therefore can guarantees that the supporting construction of support bar to gangbar both sides has identical support force, thus guarantee the stress equalization of location panel.Certainly, we also can arrange a breach on base plate, and one end that lower connection and support bar are connected with base plate is then positioned at this breach, make location panel be adjusted to horizontal level.
As Fig. 1, shown in Fig. 4, in order to provide better support to the workpiece of inclined bottom surface press-fiting in process, we also can arrange at least one workpiece mechanism 7 in the side that location panel upper surface is lower, this workpiece mechanism comprises the fixed block 71 being fixed on location panel upper surface, be positioned at 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 in splitting shape between fixed block and sliding shoe, be slidably connected by the Structure composing such as T-slot or dovetail groove between sliding shoe and location panel, to make sliding shoe can not be separated with location panel, the glide direction of sliding shoe should be consistent with the incline direction of location panel, split lateral vertical that the latch segment of shape and fixed block fit in location panel upper surface, the inclined-plane laminating that opposite side inclined-plane relative on latch segment is corresponding with sliding shoe, it sliding shoe is then the confined planes of fitting with the edge of workpiece away from the another side of latch segment, and between the bottom surface of latch segment and location panel upper surface, leave gap, like this, when latch segment moves down, the push effect of a transverse direction can be produced to sliding shoe, make the confined planes of sliding shoe near and be close to the edge of workpiece, to produce position-limiting action to workpiece.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 location panel surface through bolt through-hole rear thread, and adjusting bolt sheathed back-moving spring 75 between latch segment and location panel.Like this, rotate forward adjusting bolt and can press down latch segment like a cork, and rotate backward adjusting bolt the elastic force of back-moving spring can be utilized to make latch segment lift reset, now mode manually can move sliding shoe, thus make the confined planes on sliding shoe leave the edge of workpiece, to facilitate the dismounting of workpiece.
Further, as shown in Fig. 6, Fig. 8, first rib 721 of evagination is set in the left and right sides, inclined-plane that sliding shoe and latch segment are fitted, thus sliding shoe and latch segment side of fitting is formed 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, arranges lead 77 simultaneously, and arrange holding screw 78 junction of the edges of two sheets of paper in cylindrical hole between lead and sliding shoe; Similarly, second rib 711 of evagination is set in the left and right sides, side that fixed block and latch segment are fitted, thus fixed block and latch segment side of fitting is formed 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 axes normal of cylindrical hole is in location panel upper surface, lead is set in cylindrical hole simultaneously, and between lead and fixed block, holding screw is set the junction of the edges of two sheets of paper.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.When resetting when rising under the effect of latch segment at back-moving spring, sliding shoe can be driven to move to fixed block side, spacing with what remove workpiece, thus form linkage structure.Because cylindrical hole machines by simple drilling, lead then can assembly and disassembly easily, thus makes manufacture and safeguards 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 arrange the tapering of 5-8 degree in the end of guide pillar, and the diameter of guide pillar then should to cover the guide hole 83 coaxial with seat ring press mounting hole adaptive with engine cylinder.Like this, the guide pillar being coaxially arranged on convex neck end face can enter in advance when press-fiting in the guide hole with its adaptation, thus plays guide-localization effect, to mention the relative positional accuracy between seat ring and the press-in hole of workpiece further.
In order to ensure the guide effect between the guide hole that guide pillar and the engine cylinder of seat ring convex neck end face cover, as Fig. 9, shown in Figure 10, pedestal ring indenter can be connected with press ram 4 by Connection Block 10 by we, and circular cavity 11 is set in the lower surface of Connection Block, the madial wall of cavity along the circumferential direction compartment of terrain etc. point arranges three chutes 12 and three circular locating holes 13, chute and locating hole run through lateral wall along the radial direction of 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 radial slide bar 34, slide bar extend in chute slidably, and between the left and right sides of slide bar and chute, there is gap, thus pedestal ring indenter is suspended in the cavity of Connection Block slidably, inside cavity, alignment pin 14 is set gradually outward 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.Can to the pressure of alignment pin, thus pedestal ring indenter flexibly be floated be positioned at the centre position of cavity by regulating spring easily by rotating adjustment screw.When press-fiting, if the trueness error because of workpiece causes coaxiality deviation between pedestal ring indenter and the press mounting hole of workpiece, the guide pillar being arranged on convex neck end face still can rely on the tapering of its end to be first 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 axiality when guaranteeing to press-fit between seat ring and the press mounting hole of workpiece.
