Abstract
The utility model provides the auto-reset clamp device of the hydrostatic press mobile pumping station. The auto-reset clamp device of the hydrostatic press mobile pumping station is characterized in that: a bottom in the cylinder of the clamp cylinder is provided with an oil inlet and a center hole; a piston and a piston rod thereof are arranged in the cylinder through the center hole; the upper end of the piston is also provided with a center pole sheathed with a plurality groups of disk springs; the upper end of each disk spring is provided with a positioning pressure plate for the disk spring; ring-shaped pressing locking nuts connected with the cylinder in a screw mode are arranged on the positioning pressure plates; the upper end of the cylinder is provided with a flange for closing the cylinder and bolts for connecting a mobile pumping station; ventilating holes communicated with the upper part of the cylinder are respectively arranged on the flange and the positioning pressure plates; the interiors of the inner holes of the ring-shaped pressing locking nuts are provided with fillers for ventilating and dust-preventing. As an oil supplying system on the upper part of the cylinder of the utility model is removed, the structure is simplified, and the auto-reset clamp device of the hydrostatic press mobile pumping station is safe and reliable; in addition, the utility model has the advantages of simple structure, easy manufacturing, and low cost.
Description
Technical field
The utility model relates to the portable leveling hydraulic press of a kind of large-sized gantry, especially a kind of hydraulic press movable pump station clamping device that automatically resets.
Background technology
The portable leveling hydraulic press of large-sized gantry is widely used in auto manufacturing and the steamer manufacturing industry at present.The movable pump station of the portable leveling hydraulic press of existing large-sized gantry is positioned on the crossbeam at gantry, and movable pump station provides the power source to master cylinder and slide block.Movable pump station also has a clamping device, and this clamping device mainly is made up of two clamping cylinders.When movable pump station fixedly the time, pressure oil is to clamping cylinder forward fuel feeding, makes the piston of clamping cylinder compress the crossbeam at gantry downwards, realizes locking; When movable pump station moved, pressure oil made the piston of clamping cylinder upwards unclamp gantry crossbeam to the reverse fuel feeding of clamping cylinder, realized moving.Though the clamping device of this structure can solve the motion of movable pump station, the function that stops, locking, clamping force is less, complex structure, and the volume of whole clamping device is also big.
Summary of the invention
The utility model provides a kind of hydraulic press movable pump station simple in structure, that clamping force is big clamping device that automatically resets for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of hydraulic press movable pump station clamping device that automatically resets, be shaped on the semiclosed cylinder body of oil-in and centre bore by the bottom, be installed in the cylinder body and the piston that moves up and down in the centre bore and the piston rod of lower end thereof, be enclosed in the flange of cylinder body upper port, and the bolt that is installed in connection movable pump station on the flange is formed, the upper end of described piston also is shaped on newel, be set with array dish spring on the newel, dish spring upper end is equipped with the lower end and has the location platen that the seam center has air-vent, screw thread is equipped with the ring-like locknut that compresses that the upper end has driving hole on the cylinder body of platen upper end, location, and the ring-like locknut endoporus that compresses is equipped with ventilative dustproof filler; Also be shaped on the described flange with ring-like and compress the air-vent that the locknut endoporus communicates.
The utility model can also adopt following technical measures:
Described dish spring is 4 groups.
Advantage and the good effect that the utlity model has are: owing to add array dish spring on cylinder base is shaped on oil-in, piston, thereby make piston rod can lean on dish spring pressure to clamp gantry crossbeam, open gantry crossbeam by cylinder base voltage supply power Chinese pine, removed cylinder body top oil supply system, simplify the structure, circuit, oil circuit open circuit suddenly in the movable pump station moving process even unclamp at clamping device, this clamping device also can recover clamped condition rapidly, therefore safety, reliable, in addition the utility model also have simple in structure, be easy to make and advantage that cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, cylinder body 6 bottoms one side is shaped on the oil-in 19 that leads to side of cylinder block, and the plug screw stifled 1 that stops up fabrication hole is installed below the oil-in.The cylinder base center is shaped on centre bore 21, by centre bore piston 7 and piston rod 20 thereof is installed in cylinder body.Sealing ring 3, guidance tape 4 and the dust ring 2 of piston rod are installed in the centre bore, the sealing ring 5 and the guidance tape 8 of piston also is installed on the piston.In order to give piston pressure, also be shaped on newel 18 in the upper end of piston, on newel, be set with array dish spring 9, present embodiment is 4 groups 8.The location platen 10 that seam 17, center that the lower end has dish spring location have air-vent 22 is installed in dish spring upper end, screw thread is equipped with the ring-like locknut 11 that compresses that compresses the location platen on cylinder body upper port inwall, compresses the locknut upper surface and is shaped on the driving hole 16 that is used to install.The flange 13 of closed cylinder is installed in the upper surface of cylinder body, and the side of flange is shaped on and is communicated with the air-vent 15 compress the locknut endoporus, compresses ventilative dustproof filler 12 is housed in the locknut endoporus, so that the derivation of gas and entering during piston up-down.4 bolts 14 that connect movable pump station also are installed on the flange of cylinder body.
Operating principle:
When cylinder body oil-in input pressure oil, the pressure that pressure oil overcomes the dish spring promotes piston stroking upward, and piston rod unclamps gantry crossbeam, and movable pump station moves; When the cylinder body oil-in stopped the pressure oil input, the dish spring resetted, and promotes descent of piston immediately, and piston rod clamps gantry crossbeam, and movable pump station is fixed.
Claims (2)
1. hydraulic press movable pump station clamping device that automatically resets, be shaped on the semiclosed cylinder body of oil-in and centre bore by the bottom, be installed in the cylinder body and the piston that moves up and down in the centre bore and the piston rod of lower end thereof, be enclosed in the flange of cylinder body upper port, and the bolt that is installed in connection movable pump station on the flange is formed, it is characterized in that: the upper end of described piston also is shaped on newel, be set with array dish spring on the newel, dish spring upper end is equipped with the lower end and has the location platen that the seam center has air-vent, screw thread is equipped with the ring-like locknut that compresses that the upper end has driving hole on the cylinder body of platen upper end, location, and the ring-like locknut endoporus that compresses is equipped with ventilative dustproof filler; Also be shaped on the described flange with ring-like and compress the air-vent that the locknut endoporus communicates.
