Description of reference numerals: 1-oscillating oil cylinder, 2-axle bed, 3-trip shaft, 4-pivoted arm, 5-rolling bearing, 6-fixed axis, 7-bolster, 8-bowl-type claw, 9-bearing (ball) cover, 10-positioning sleeve, 11-bearing, 12-sand draining port, 13-roller, 14-sandbox, 15-sandbox hanger.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the utility model mainly is made up of turning device 1, trip shaft 3, pivoted arm 4, rolling bearing 5, fixed axis 6, bolster 7, bowl-type claw 8, bearing (ball) cover 9, positioning sleeve 10, bearing 11 and roller 13, trip shaft logical 3 crosses bearing 11 and positioning sleeve 10 is installed in the axle bed 2, bearing (ball) cover 9 encapsulation are adopted in the end of axle bed 2, the bearing 11 preferred taper roll bearings that adopt; Trip shaft 3 adopts flat key to be connected with the output shaft of turning device 1 and rotates synchronously, and an end of pivoted arm 4 adopts and is bolted on the trip shaft 3, rotates along with the rotation of trip shaft 3; The other end at pivoted arm 4 is equipped with fixed axis 6, and bowl-type claw 8 is installed on the fixed axis 6 by rolling bearing 5 and can freely rotates around fixed axis 6; Bolster 7 is fixed on the bowl-type claw 8, and roller 13 is installed in the bowl-type claw 8 by bolster 7, and roller 13 can freely rotate around bolster 7.
As shown in Figure 2, described turning device 1 adopts oscillating motor of the prior art, and oscillating motor is an axle output bidentate stripe shape, and its linear reciprocating motion by piston is converted into forward and reverse revolution of rack drives gear, and the output torque, oscillating motor provides driving source by Hydraulic Station.
As shown in Figure 3, the utility model occurs in molding, mould turnover, flow coater in pairs, to realize clamping and the upset work to large scale, large-tonnage sandbox, its working condition is as follows: after bowl-type claw 8 held up sandbox 14, sandbox hanger 14 directly was pressed on the roller 13; Provide driving source by Hydraulic Station to oscillating motor, oscillating motor drives trip shaft 3 and rotates, and then drives pivoted arm 4 rotations, and sandbox 14 overturns along with the rotation of pivoted arm 4; In switching process, bowl-type claw 8 is remaining the state vertically downward shown in Fig. 3 owing to be subjected to the effect of sandbox 14 gravity, is rolling friction between sandbox hanger 15 and the roller 13, assurance bowl-type claw 8 is held sandbox hanger 15 all the time, to finish the mould turnover action; The bottom of described bowl-type claw 8 offers sand draining port 11, and the molding sand that enters in the course of the work in the bowl-type claw 8 can spill by sand draining port 11, influences equipment operation to prevent to occur long-pending sand in the bowl-type claw 8.
