Abstract
The utility model relates to a drive mechanism, which comprises an oil cylinder an oil cylinder seat, wherein the oil cylinder is provided with a piston rod which can stretch basically along the horizontal direction, the head of the piston rod is provided with a furring bracket, and the height of the furring bracket is suitable for keeping the piston rod to move in a reciprocating way along the horizontal direction. With the stabilization of the furring bracket, the drive mechanism leads the two ends of the piston rod to be supported in a horizontal plane, and is good for keeping the piston rod to move along the horizontal direction when working, so that the defects of oil leakage and inclination as the durative accumulation of head migration caused by adverse factors of dead weight and the like can be further overcome.
Description
Technical field
The utility model relates to casting field and is used to promote a kind of driving mechanism that sandbox moves.
Background technology
In the casting and molding transfer matic, sandbox will move on the roller frame of limit under the promotion of oil cylinder, owing to be the moving of level position, therefore when oil cylinder injustice or sandbox were oversize, the piston rod of oil cylinder need too stretch out or stretch out long to satisfy requirement of actual working condition, in this state, because deadweight, sagging situation or trend can appear in the piston rod front end of oil cylinder, under the continuous accumulation of this situation, after time was long, the phenomenon of oil cylinder leakage of oil will appear.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of and can suitably adjusts the piston rod use location, can avoid the improper user mode of piston rod lasting accumulative total, increase the service life, reduce the driving mechanism of service wear; Its technical problem to be solved can be implemented by the following technical programs.
A kind of driving mechanism comprises oil cylinder and oil cylinder seat thereof, and described oil cylinder has the basic piston rod flexible along the level position, and described piston rod head is provided with a bed hedgehopping support, and the bed hedgehopping height of described bed hedgehopping support is suitable for the reciprocating motion of described piston rod maintenance level position.
As the further improvement of the technical program, described bed hedgehopping support and described piston rod head can be connected to one.
Also as the further improvement of the technical program, described bed hedgehopping support can also have been set up the roller of advancing.
Adopt the driving mechanism of this technical scheme, by stablizing of a bed hedgehopping support, make the piston rod two ends be supported in the plane of a level, motion when helping piston rod work on the maintenance level position, and then overcome because the leakage of oil that the head bias that unfavorable factors such as deadweight are brought occurs under lasting accumulation and the deficiency of inclination.And can be by the mode of setting up roller or connecting as one, make piston rod motion more freely.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model being done one describes in detail.
Fig. 1 is a structural representation of the present utility model;
---oil cylinder 11---oil cylinder seat 12---piston head among the figure: 1
2---guiding trestle 3---roller 4---support 5---sandboxes
The specific embodiment
Driving mechanism as shown in Figure 1, on support 4, be provided with an oil cylinder seat 11, the piston rod front end that is placed in the oil cylinder 1 on the oil cylinder seat 11 is a piston head 12, below piston head 12, be provided with a guiding trestle 2, guiding trestle 2 is along the flexible direction setting of piston rod, and piston head 12 taken naturally be placed on above the guiding trestle 2, so that whole piston rod keeps level.
Be provided with running roller 3 in guiding trestle 2 lower ends, piston head 12 leans on sandbox; The guiding trestle 2 that the piston rod front end of oil cylinder 1 is installed is when piston rod stretches out, guiding trestle passes in and out simultaneously with the oil cylinder piston bar, guiding trestle is the same with sandbox to be moved on running roller, can effectively solve the piston rod sagging problem like this, sandbox is pushed by oil cylinder and makes the oil cylinder piston bar can not be sagging when moving forward.
The long piston rod front end that causes of piston rod of oil cylinder was sagging when this device efficiently solved the propelling movement sandbox, and the serious problem of oil cylinder leakage of oil is overcome, and reliability helps a kind of good working order of the long-term maintenance of piston rod than higher.
