Abstract
The utility model discloses a bonnet pressing sleeve pulling machine. The bonnet pressing sleeve pulling machine comprises an oil cylinder (1), a piston rod (2), a positioning seat (3), a pressing sleeve (4) and a pull rod (10), and is characterized in that the positioning seat (3) is of an integrated structure, the pull rod (10) is of a reducing structure, and the oil cylinder (1), the piston rod (2), the positioning seat (3), the pressing sleeve (4) and the pull rod (10) are provided with a same central shaft. The positioning seat is of the integrated structure, so that stability of parts is enhanced. Since the oil cylinder (1), the piston rod (2), the positioning seat (3), the pressing sleeve (4) and the pull rod (10) are provided with the same central shaft, accuracy and quality of the parts can be effectively improved, and the trouble in detaching the pressing sleeve with the parts different in size from the piston rod is avoided by the reducing pull rod.
Description
Technical field
The utility model relates to the valve technology field, relates in particular to a kind of machine of helping pull a cart for the valve gap gland.
Background technology
At present, method to part such as valve gap gland has employing manual, the mechanical means of employing is also arranged as adopting hydraulic sleeve drawing, and patent No. CN201366691Y openly points out to adopt the method for hydraulic sleeve drawing, but in the practical operation, because the design of part parts is too scattered, brings unnecessary trouble to installation, in addition, when part is carried out gland, owing to not have strict fixedly gland parts and by the position of gland part, so that precision appears in the parts that gone out by gland is not high, non-conformity of quality closes the defective of requirement.
The utility model content
Based on the defects that prior art exists, the utility model provides a kind of machine of helping pull a cart for the valve gap gland, a kind of simple in structure, easy to operate, high rod-pulling type press take hydraulic pressure as power of production efficiency.
A kind of machine of helping pull a cart for the valve gap gland that the utility model provides comprises oil cylinder, piston rod, positioning seat, gland and pull bar; Wherein said positioning seat is the integral type structure; Described pull bar is variable-diameter structure; Described oil cylinder, piston rod, positioning seat, gland and pull bar are provided with same central shaft.
The first preferred machine of helping pull a cart that is used for the valve gap gland that the utility model provides, described positioning seat integral structure is that positioning seat is made of annular plectane and hollow pipe; And annular plectane is positioned at the upper end of hollow pipe.
The second preferred machine of helping pull a cart that is used for the valve gap gland that the utility model provides, described pull bar variable-diameter structure is that pull bar is connected and composed by the different pipe of internal diameter.
Positioning seat adopts integral structure, equipment is installed easier, and oil cylinder, piston rod, positioning seat, gland and pull bar are provided with same central shaft, strictly control by the position of gland part precision and the quality of Effective Raise gland part.
In addition, oil circuit of the present utility model is connected with hydraulic control panel by wire, and overflow valve is housed in the oil piping system; Two height operating pressures that overflow valve is oil circuit control, the reciprocating motion of oil cylinder are that the moving three position four-way directional control valve of armrest is realized
The method of implementing high pressure is before low pressurized overflow manual two-position four way change valve to be housed, and just cuts off the duty of cancellation low pressure relief valve when the cutoff low oil circuit, and high-pressure overflow valve is come into operation, and said method should could be realized when two valves use simultaneously.The method that enforcement is returned at a high speed is the same with Pressure Increasing Oil-Line, and difference is to adopt 3-position 4-way hand-operated direction valve handle to answer reverse operating, and the utility model mechanism reaches microinching by the meter out control of flow control valve.
Description of drawings
The structural representation of a kind of machine of helping pull a cart for the valve gap gland that Fig. 1 provides for the utility model.
Among the figure: 1, oil cylinder; 2, piston rod; 3, positioning seat; 4, gland; The part of 5, being helped pull a cart; 6, hydraulic control panel; 7, frame; 8, base; 9, loam cake; 10, pull bar; 11, guide.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
A kind of machine of helping pull a cart for the valve gap gland that the utility model provides comprises oil cylinder 1, piston rod 2, positioning seat 3, gland 4 and pull bar 10; Oil cylinder 1 is bolted on the base 8 of frame 7, base 8 and loam cake 9 all are bolted on the pillar of frame 7, the upper end of oil cylinder 1 is by arranging adapter sleeve or being fixed on the oil cylinder 1 by the end of bolt with piston rod, the other end of piston rod 2 is connected with pull bar 10 by another adapter sleeve, piston rod 2 all can be in the lower axially-movable of the effect of oil circuit pressure with pull bar 10, in addition, the upper end of piston rod 2 is positioned at the below of loam cake 9 under normal conditions, loam cake 9 is provided with the through hole of laying positioning seat 3, positioning seat 3 is provided with through hole equally, and be provided with annular boss in the positioning seat 3, when preventing that piston rod from axially moving, go out the loam cake 9 of frame 7 because dynamics is excessive, pull bar 10 can pass the through hole of positioning seat 3, pull bar 10 is made of the pipe of different inner diameters herein, with adapt to different sizes by the gland part, gland 4 is fixed by guide in the upper end of pull bar 10, the upper end of gland 4 adopts nut to be fixed on the pull bar 10 in addition, prevent that gland from coming off, and as shown in Figure 1, can be placed between gland 4 and the positioning seat 3 by gland part 5, during practical operation, to be fixed on the pull bar 10 by gland part 5, the be fixed lower end of part 5 can place in the positioning seat 3, and suitable with the hole on the positioning seat 3, then positioning sleeve is passed by the through hole of gland part 5, at this moment, oil circuit is exerted pressure, pulling piston rod 2 and pull bar 10 axially-movables are so that the parts of pull bar 10 ends are drawn in the hole of the part 5 of being helped pull a cart.
When oil cylinder 1, piston rod 2, positioning seat 3, gland 4 and pull bar 10 are provided with same central shaft, the part at gland place because stressed evenly, its precision is higher, and quality is improved greatly.During practical operation, also can the pipe formation pull bar of different inner diameters be installed according to by the size of gland part, can effectively protect equipment not to be damaged like this, improve its service life.
Those skilled in the art should be understood that; piston rod becomes variable-diameter structure according to the height design of oil cylinder; and piston rod and pull bar adopt material as required; in addition; also can improving in shape of hole in the positioning seat; be provided with stair-stepping hole such as inside, above-mentioned distortion all should be contained within the protection domain of the present utility model creation.
