Abstract
The utility model provides a mechanical-seal stationary seal ring press-in device belonging to the field of machine tools. The mechanical-seal stationary seal ring press-in device comprises a handwheel, a screw rod, an upper guiding nut, an auxiliary frame, a lower guiding nut, a main frame, a guiding head and a stationary seal ring pressing plate, which are arranged from the top down; the main frame is connected with a machine to be loaded with a stationary seal ring; the auxiliary frame is fixed at the upper end of the main frame; run-through through holes are formed in the central position of the main frame and the central position of the auxiliary frame; the lower guiding nut is fixed on the upper side of an upper end port of the through hole of the main frame; the upper guiding nut is fixed on the upper side of an upper end port of the through hole of the auxiliary frame; the screw rod is screwed between the upper and the lower guiding nuts; the upper end and the lower end of the screw rod extend from the main frame and the upper guiding nut; the handwheel is arranged at the upper end of the screw rod; the guiding head is arranged at the lower end of the screw rod; and the stationary seal ring pressing plate is mounted on the guiding head. Due to the implementation of the technical scheme, the mechanical-seal stationary seal ring press-in device has the advantages that the stationary seal ring is mounted conveniently, and the damage to the stationary seal ring during the mounting process is avoided.
Description
Technical field
The machine envelope stationary ring press-in device of the utility model belongs to the machine tool field, relates in particular to a kind of machine envelope stationary ring press-in device.
Background technology
The stationary ring sealing is the common seal form of a kind of ten minutes, uses very extensive.But in the process that it is overhauled and installs, the phenomenon that stationary ring is difficult for installation usually occurs, especially large-sized fragility stationary ring is very easily broken in installation, has brought unnecessary trouble and serious economy loss to service work.
Summary of the invention
The purpose of the utility model is to propose a kind of stationary ring that makes things convenient for and installs, can be with the machine envelope stationary ring press-in device of its damage in the installation process.
The purpose of the utility model is achieved in that machine envelope stationary ring press-in device, is made up of handwheel, leading screw, last spigot nut, secondary frame, following spigot nut, mainframe, guide head and stationary ring pressing plate from top to bottom.Mainframe be housed to the mechanical connection of stationary ring, be fixed with secondary frame in the mainframe upper end, have the through hole of perforation in mainframe and secondary frame central position; Through hole port upside at mainframe is fixed with spigot nut down, and spigot nut on the through hole port upside of secondary frame is fixing is connected with leading screw between upper and lower spigot nut; Leading screw stretches out mainframe and last spigot nut in two ends up and down; The leading screw upper end is equiped with handwheel, and the lower end is equiped with guide head, on guide head, is equiped with the stationary ring pressing plate.
Owing to implement above technical scheme, make the machine envelope stationary ring press-in device of the utility model make things convenient for stationary ring to install, can not cause damage in the installation process to stationary ring.
Description of drawings: the concrete structure of the utility model is provided by following accompanying drawing and embodiment:
Fig. 1 is a machine envelope stationary ring press-in device structural representation.
Legend: 1, handwheel, 2, leading screw, 3, go up spigot nut, 4, secondary frame, 5, spigot nut down, 6, mainframe, 7, screw, 8, guide head, 9, the stationary ring pressing plate.
The specific embodiment: the utility model is not limited by the following examples, and can confirm concrete embodiment according to the technical scheme and the actual conditions of the utility model.
Embodiment: as shown in Figure 1, machine envelope stationary ring press-in device is made up of handwheel 1, leading screw 2, last spigot nut 3, secondary frame 4, following spigot nut 5, mainframe 6, guide head 8 and stationary ring pressing plate 9 from top to bottom.Mainframe 6 and the mechanical connection that is housed to stationary ring; Be fixed with secondary frame 4 in mainframe 6 upper ends, have the through hole of perforation, be fixed with spigot nut 5 down at the through hole port upside of mainframe 6 at mainframe 6 and secondary frame 4 center positions; Spigot nut 3 on the through hole port upside of secondary frame 4 is fixing; 3,5 of upper and lower spigot nuts are connected with leading screw 2, and leading screw stretches out mainframe 6 and last spigot nut 3 in two ends about in the of 2, and leading screw 2 upper ends are equiped with handwheel 1; The lower end is equiped with guide head 8, on guide head 8, is equiped with stationary ring pressing plate 9.
During use, machine is sealed the stationary ring press-in device through mainframe 6 and the mechanical connection that is housed to stationary ring, stationary ring pressing plate 9 lies on the stationary ring, and guide head 8 is pressed on the stationary ring pressing plate 9, rotates handwheel 1, can be with mild, harmless the packing into of stationary ring.
Above technical characterictic has constituted the most preferred embodiment of the utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
