Abstract
The utility model belongs to the technical field of a hydraulic transmission mechanism and particularly relates to a hydraulic actuator for disassembling inner sleeves in interference fit. The hydraulic actuator comprises an oil cylinder body consisting of a positioning end seat, an oil cylinder sleeve and a fixed sliding sleeve, wherein the oil cylinder sleeve is provided with an oil opening I and an oil opening II, a set of piston assembly is arranged in the oil cylinder sleeve and consists of a hollow piston, a front sliding sleeve, a rear sliding sleeve, a screw, a pawl head and a nut, the hollow piston is arranged between the oil opening I and the oil opening II on the oil cylinder sleeve, the outer surface of the front sliding sleeve is in sliding connection with a sliding hole of the positioning end seat, and the outer surface of the rear sliding sleeve is in sliding connection with the inner surface of the fixed sliding sleeve. The hydraulic actuator can be used for conveniently and quickly disassembling spare parts such as an inner steel sleeve and a copper sleeve in a crusher and a valve seat in a diaphragm pump in a labor-saving manner and especially has remarkable advantages in application occasions with narrow disassembling space and high manual difficulty.
Description
Technical field
The utility model belongs to the fluid drive mechanism technical field, especially relates to a kind of hydraulic pressure execution device of dismantling cover in the interference fit.
Background technique
In service work for many years, the Hydraulic power tools that dismounting is often used to some interference assembling parts, such as adopting hydraulic pressure to grab the overcoat of dismounting endoporus interference, simple to operate, laborsaving and to the workpiece not damaged.But when dismantling the interior cover of some outer round surface cooperations with it, it is powerless just to seem.For example, the spare parts such as valve seat in the interior steel bushing in the disintegrator, copper sheathing, the diaphragm pump are after wearing and tearing; When needing to remove, often all be that this spare part is destroyed, could remove then; Most so all easily with the spare part damage that is mated, for assembling next time brings the accident potential in the operation.And labor intensity is big, and is dangerous, waste time and energy, and when having increased the check man greatly, brings very big waste to enterprise, strengthened operation cost.
Summary of the invention
The utility model provides a kind of hydraulic pressure execution device of dismantling cover in the interference fit, simplifies the dismounting operation, saves human and material resources, improves operating efficiency.
The purpose of the utility model realizes through following technical proposals:
A kind of hydraulic pressure execution device of dismantling cover in the interference fit of the utility model; Comprise cylinder body; This cylinder body is by the positioning end seat that has slide opening; The one end fixedly sliding sleeve that is fixedly connected with the other end internal surface of oil cylinder cover therewith of the oil cylinder cover that is fixedly connected of positioning end seat is therewith formed, and described oil cylinder puts to be provided with and leads to hydraulic fluid port I and logical hydraulic fluid port II, it is characterized in that described oil cylinder is provided with one in overlapping and overlaps piston assembly; This piston assembly is by overlapping the box type piston that internal surface is slidingly connected with described oil cylinder; The preceding sliding sleeve that is fixedly connected of box type piston internal surface therewith, therewith before the back sliding sleeve that is fixedly connected of sliding sleeve, intert said before sliding sleeve with after screw rod in the sliding sleeve endoporus; Therewith the ratchet head that is threaded of screw front end and therewith the nut that is threaded of spiro rod rear end form; Described box type piston is between logical hydraulic fluid port I and logical hydraulic fluid port II that said oil cylinder puts, and the outer surface of said preceding sliding sleeve and the slide opening of said positioning end seat are slidingly connected, and the outer surface and the described fixedly sliding sleeve internal surface of said back sliding sleeve are slidingly connected.
The advantage of the utility model:
Spare parts such as valve seat in interior steel bushing in employing the utility model dismounting disintegrator, copper sheathing, diaphragm pump occasion convenient, fast, laborsaving, especially narrow and small in the withdrawal space, manual difficulty more shows advantage.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Like Fig. 1, shown in 2; A kind of hydraulic pressure execution device of dismantling cover in the interference fit of the utility model; Comprise cylinder body, the oil cylinder cover 5 that is fixedly connected of positioning end seat 8 and oil cylinder therewith overlap 3 compositions of fixedly sliding sleeve that 5 the other end internal surface is fixedly connected to this cylinder body therewith by positioning end seat 8, one ends that have slide opening; Described oil cylinder cover 5 is provided with logical hydraulic fluid port I 4 and logical hydraulic fluid port II 7; It is characterized in that being provided with in the described oil cylinder cover 5 a cover piston assembly, this piston assembly is by overlapping the box type piston 6 that 5 internal surfaces are slidingly connected with described oil cylinder, therewith the preceding sliding sleeve 11 that is fixedly connected of box type piston 6 internal surfaces; The back sliding sleeve 2 that preceding therewith sliding sleeve 11 is fixedly connected; Intert screw rod 9 in before said sliding sleeve 11 and back sliding sleeve 2 endoporus, the ratchet head 10 that is threaded of screw front end and 1 composition of nut of being threaded of spiro rod rear end therewith therewith, described box type piston is between logical hydraulic fluid port I and logical hydraulic fluid port II that said oil cylinder puts; The whole internal cavities of oil cylinder cover 5 is divided into two independently hydraulic fluid chambers; These two independently hydraulic fluid chamber be connected with oil pump with logical hydraulic fluid port II through described logical hydraulic fluid port I respectively, said before outer surface and the slide opening of said positioning end seat 8 of sliding sleeve 11 be slidingly connected, the said outer surface of sliding sleeve 2 afterwards and the internal surface of said fixedly sliding sleeve 3 are slidingly connected.Box type piston 6 in above-mentioned, forward and backward sliding sleeve 11,2 are formed a composite entity that is slidingly connected with cylinder body, and screw rod 9 penetrates wherein and by just moving backward with this composite entity after the nut check, removes interior cover thereby drive ratchet head 10.
The outer surface of described box type piston 6 is provided with sealing lead ring assembly 12.
Claims (2)
1. dismantle the hydraulic pressure execution device that overlaps in the interference fit for one kind; Comprise cylinder body; This cylinder body is by the positioning end seat that has slide opening; The one end fixedly sliding sleeve that is fixedly connected with the other end internal surface of oil cylinder cover therewith of the oil cylinder cover that is fixedly connected of positioning end seat is therewith formed, and described oil cylinder puts to be provided with and leads to hydraulic fluid port I and logical hydraulic fluid port II, it is characterized in that described oil cylinder is provided with one in overlapping and overlaps piston assembly; This piston assembly is by overlapping the box type piston that internal surface is slidingly connected with described oil cylinder; The preceding sliding sleeve that is fixedly connected of box type piston internal surface therewith, therewith before the back sliding sleeve that is fixedly connected of sliding sleeve, intert said before sliding sleeve with after screw rod in the sliding sleeve endoporus; Therewith the ratchet head that is threaded of screw front end and therewith the nut that is threaded of spiro rod rear end form; Described box type piston is between logical hydraulic fluid port I and logical hydraulic fluid port II that said oil cylinder puts, and the outer surface of said preceding sliding sleeve and the slide opening of said positioning end seat are slidingly connected, and the outer surface of said back sliding sleeve and the internal surface of said fixedly sliding sleeve are slidingly connected.
