Detailed description of the invention
As Fig. 1, 3, shown in 4, one guide roll mechanism, on rod unit 10 bodies of rod, offer the axis hole of wearing connection for rotating pin 20, the end that is positioned at the rotating pin 20 in rod unit 10 outside is connected with roller 30, roller 30 is placed in the guide rail 40 of groove type, the wheel face of roller 30 coordinates with the cell wall formation rolling of the groove that forms guide rail 40, on roller 30, offer the through hole for rotating pin 20 companies of wearing, the flute length direction of offering draw-in groove 23 and draw-in groove 23 on the axle body of the rotating pin 20 of rod unit 10 inner sides is axial vertical with rotating pin 20, rod unit 10 inner sides arrange postive stop baffle 60 and are placed in draw-in groove 23, postive stop baffle 60 is that screw is connected with rod unit 10 inner side, on the bottom land of the groove of formation guide rail 40, offer through hole 41, the Kong Xin of through hole 41 is positioned on rotating pin 20 motion paths, the aperture of through hole 41 is greater than the maximum gauge value of rotating pin 20.Adopt above-mentioned connection structure easily pair roller 30 dismantle and install, its demounting procedure is as follows: first will prop up rod unit 10 and push to through hole 41 positions along guide rail 40, be opened in the limit station place initial position in other words of a rod unit 10 as preferred version through hole 41 of the present utility model, now prop up rod unit 10 like this in disassembly process rod unit 10 can keep stable, then the bolt shown in Fig. 4 61 is backed out, postive stop baffle 60 is extracted from draw-in groove 23, now only need just it can be taken out from through hole 41 to 20 1 axial external force of rotating pin, the last end that as shown in Figure 2 roller 30 is pushed to guide rail 40 along the length direction of guide rail 40 is taken out again, or also roller 30 can be pushed into the place that hole 41 sides do not block by rod unit 10 then take out roller 30 from the groove of guide rail 40, the installation steps of roller 30 are contrary with above-mentioned demounting procedure.
As shown in Figure 1, 2, one end that rotating pin 20 coordinates with roller 30 is provided with the ring flange 22 and the ring flange 22 that radially outwards stretch and is resisted against on the end face of roller 30, ring flange 22 can prevent that roller 30 from sliding on the axis direction of rotating pin 20, makes the axial location of rod unit 10 and roller 30 constant and then ensure that a rod unit 10 is more stable in motion process.
As shown in Figure 2, rolling on face of roller 30 is provided with near one end of a rod unit 10 wheel rim 32 extending radially outward, described wheel rim 32 is positioned at the notch outside of the groove that forms guide rail 40 and is resisted against on the cell wall end face at notch place, between described roller 30 and rotating pin 20, be provided with copper sheathing 50, one end of described copper sheathing 50 is provided with outside flange 51, and described flange 51 is between roller 30 and rod unit 10 and fit with the two.Wheel rim 32 can prevent the bottom land place skew of roller 30 direction guiding rails 40, can avoid the end face of roller 30 and guide rail 40 to produce friction, can ensure that again a rod unit 10 can not produce skew in motion process; Adopting copper sheathing 50 is in order to reduce friction, copper sheathing 50 is also more wear-resisting simultaneously, can improve 30 life-spans of roller, in addition, the flange 51 of copper sheathing 50 is clipped between roller 30 and a rod unit, has avoided the end face of roller 30 directly contact and produce larger friction force with a rod unit, and general run of thins bottom roller 30 and copper sheathing 50 are interference fit, the two is connected as a single entity, so copper sheathing 50 and roller 30 are installation or removal simultaneously.
As shown in Figure 2, roller 30 is provided with circular-shaped, concave cavity 31 near the end face of guide rail 40 1 sides, the diameter of described cavity 31 is more than or equal to the diameter of ring flange 22, described ring flange 22 is contained in cavity 32, thereby be to maintain a certain distance and avoid friction between rotating pin 20 and guide rail 40 in order to allow like this, also make structure compacter, attractive in appearance simultaneously.
As shown in Figure 1, rotating pin 20 inside are provided with oil duct 21, the inwall of described copper sheathing 50 is provided with oil groove 52, the oil inlet of described oil duct 21 is positioned on the end face of rotating pin 20, and the oil outlet of described oil duct 21 is positioned on the face of cylinder of rotating pin 20 and is corresponding with oil groove 52 positions on copper sheathing 50.Oil duct 21 can guide to lubricating oil in the oil groove 52 of copper sheathing 50, and then lubricating oil infiltrates between copper sheathing 50 inside faces and the periphery of rotating pin 20, has reduced to greatest extent the friction force between the two.
