Abstract
The utility model discloses the lifting device of traverser in compression machine, comprise cylinder body, piston and gland, between piston and cylinder body, there is gap, piston coordinates with cylinder body seal by wadding, gland is enclosed within on piston and with the upper end of cylinder body and is fixedly connected with, the upper end of piston is fixedly connected with the top board that is useful on jack-up traverser, the lower end of piston is fixedly connected with piston rod, piston rod passes cylinder body downwards, feature is to be provided with flow ring between piston and cylinder body, the lower end of piston rod is bolted with nut, upper cover of piston rod has retracing spring, retracing spring apical grafting between nut and the lower surface of cylinder body, advantage is in the time that traverser shift-in puts in place, under the self gravitation of top board and piston and the elastic force effect of retracing spring, drive piston to move down reset, ensure the reset completely of piston, avoid bumping, and owing to being provided with flow ring between piston and cylinder body, effectively protect the life-span of piston and wadding, also increased the guide function of piston simultaneously.
Description
Technical field
The utility model relates to compression machine, relates in particular to the lifting device of traverser in compression machine.
Background technology
Traverser in compression machine is mainly used in the replacing of mould, while not needing to use, traverser is fixed and is placed in the basis or base of compression machine, in the time that needs use traverser, first, by traverser jack-up from basis or base, then traverser is moved to the mould below of compression machine.
At present, traverser adopts oil cylinder by its jack-up upwards conventionally, but due to the load weight of oil cylinder, the wadding between piston and cylinder body easily damages, and in the time having unbalance loading, piston may be stuck at midway location, and can not arrive initial bit; In addition, when piston does not arrive initial position, and while having traverser to travel, may there is impact events above.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of lifting device of traverser in compression machine that piston resets, avoids to occur to clash into completely that ensures.
The utility model solves the problems of the technologies described above adopted technical scheme: the lifting device of traverser in compression machine, comprise cylinder body, piston and gland, between described piston and described cylinder body, there is gap, described piston coordinates with described cylinder body seal by wadding, described gland is enclosed within on described piston and is fixedly connected with the upper end of described cylinder body, prevent that piston from skidding off cylinder body, the upper end of described piston is fixedly connected with the top board that is useful on jack-up traverser, the lower end of described piston is fixedly connected with piston rod, described piston rod passes described cylinder body to lower seal, the lower end of described cylinder body is provided with oil inlet, between described piston and described cylinder body, be provided with flow ring, the lower end of described piston rod is bolted with nut, described upper cover of piston rod has retracing spring, described retracing spring apical grafting is between described nut and the lower surface of described cylinder body.
The lower end of described cylinder body is fixedly connected with and detects seat, and described detecting on seat is fixedly installed two upper and lower spaced detecting switches, and described detecting switch is positioned at a side and the close described piston rod of described piston rod.
The upper end of described cylinder body is fixedly connected with adapter plate, and described adapter plate is pressed on described gland and is fixedly connected with described gland by screw.
Compared with prior art, the utility model has the advantages that owing to being provided with retracing spring on piston rod, in the time that traverser shift-in puts in place, under the self gravitation of top board and piston and the elastic force effect of retracing spring, drive piston to move down reset, pressure oil is by oil inlet oil return, ensure the reset completely of piston, avoid bumping, and owing to being provided with flow ring between piston and cylinder body, effectively protect the life-span of piston and wadding, avoided wearing and tearing and leakage of oil between piston and cylinder body, also increased the guide function of piston simultaneously; In addition, because the side near piston rod is provided with two upper and lower spaced detecting switches, piston be can be detected in lifting state or falling state by nut near upper detecting switch or lower detecting switch, device lifting and the reliability falling ensured.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
