Abstract
The invention relates to a hydraulic cylinder with a separated cylinder end and an easily replaced sealing member. The hydraulic cylinder comprises a cylinder body, a piston rod, a piston and a cylinder end, wherein the piston rod is arranged in the cylinder body, the piston is arranged on the piston rod, the cylinder end is sleeved on the piston rod and fixedly connected with the end part of the cylinder body, the cylinder end comprises the separated cylinder end and a gland, the end face of the tail part of the separated cylinder end and one end of the cylinder body are fixedly installed, a guide member sleeved on the piston rod is arranged in the separated cylinder end, the gland is of a convex circular truncated cone shape and is provided with a flange and a convex part, the flange of the gland and the end face of the mouth part of the separated cylinder end are fixedly installed, the convex part of the gland is inserted in the separated cylinder end and supports against the guide member, an O-shaped ring is arranged between the outer wall of the convex part and the inner wall of the separated cylinder end, and a sealing member is arranged on the inner wall of the top of the convex part of the gland. By adopting the separated cylinder end, the sealing member is arranged on the gland, thus the sealing part is conveniently maintained and replaced, and the working efficiency is increased.
Description
Technical field
The present invention relates to technical field of hydraulic oil cylinder, especially a kind of split cylinder head hydraulic jack that is easy to change Sealing.
Background technique
In traditional hydraulic jack, cylinder head is independent as a whole, and cylinder head is fixedly connected with cylinder body; And the Sealing that is used for sealing is directly installed on the groove in the cylinder head with the guiding element that play the guiding role, and traditional oil cylinder advantages of simple design, the problem that all-in-one-piece cylinder head design brings are that installation Sealing and guiding element are the comparison difficulties; Need the certain operation skill of staff; Also reflect from this respect and the height of cost to have such problem for the traditional hydraulic jack of the replacing of Sealing in addition, when needs are changed; Need whole cylinder head be pulled down; Again Sealing is taken out, and the Sealing taking-up is also cumbersome, therefore aspect safeguarding, also has the problem of inconvenience.
Summary of the invention
The technical problem that the present invention will solve is: in order to solve the technical problem that cylinder seal spare is difficult for changing in the existing technology, a kind of split cylinder head hydraulic jack that is easy to change Sealing is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of split cylinder head hydraulic jack that is easy to change Sealing, comprise cylinder body, piston rod, piston and cylinder head, and said piston rod is arranged in the cylinder body; Said piston is installed on the piston rod, and said cylinder head is set on the piston rod and with cylinder ends and fixedly mounts, and said cylinder head comprises split cylinder head and gland; Said split cylinder head tail end face and the fixed installation of cylinder body one end; Be provided with the guiding element that is sleeved on the piston rod in the split cylinder head, said gland is dome platform shape, has flange and protuberance; The oral area end face fixed installation of the flange of gland and split cylinder head; The protuberance of gland inserts in the split cylinder head and withstands guiding element, between said protuberance outer wall and the split cylinder head inwall O type circle is installed, and on the top inner wall of said gland protuberance Sealing is installed.
Sealing and O type circle are not installed on the guiding element among the present invention, but these all are installed on the gland, so just can be convenient for changing Sealing and O type circle, need not remove cylinder head fully, only need pull down gland and just can change fast.
The invention has the beneficial effects as follows; The split cylinder head hydraulic jack that is easy to change Sealing of the present invention adopts split type cylinder head design, has reduced difficulty of processing; Guaranteed the machining accuracy of part; Also obtain solution for the difficult problem of changing of Sealing simultaneously, saved the operating time greatly, improved working efficiency.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation that is easy to change the split cylinder head hydraulic jack of Sealing of the present invention;
Fig. 2 is the A place enlarged view of Fig. 1.
Among the figure: 1. hanger, 2. piston rod, 3 glands, 31. flanges, 32. protuberances, 4.O type circle, 5. Sealing, 6. guiding element, 7. split cylinder head, 8. cylinder body.
Embodiment
Combine accompanying drawing that the present invention is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Shown in Fig. 1 ~ 2, the split cylinder head hydraulic jack that is easy to change Sealing of the present invention comprises cylinder body 8, piston rod 2, piston and cylinder head; Piston rod 2 is arranged in the cylinder body 8, is fixedly connected hanger 1 on the external part of piston rod 2, and piston is installed on the piston rod 2; Cylinder head is set on the piston rod 2 and with cylinder body 8 end screws and is connected, and cylinder head comprises split cylinder head 7 and gland 3, and split cylinder head 7 tail end faces are connected with cylinder body 8 one end screws; Be provided with the guiding element 6 that is sleeved on the piston rod 2 in the split cylinder head 7, gland 3 is dome platform shape, has flange 31 and protuberance 32; The flange 31 of gland 3 is connected with the oral area end face screw of split cylinder head 7; The protuberance 32 of gland 3 inserts in the split cylinder head 7 and withstands guiding element 6, between protuberance 32 outer walls and split cylinder head 7 inwalls O type circle 4 is installed, and oil just can not spill between split cylinder head 7 and gland 3 like this; On the top inner wall of gland 3 protuberances 32 Sealing 5 is installed, having guaranteed so can leakage of oil on the piston rod 2.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
