Background technology
In a lot of plant equipment, other ancillary equipment need be installed in a lot of fuel tank or the casing outside that liquid medium is housed, and this ancillary equipment adopts sealed self-locking nut assembly to be fixed on casing mostly.Because fuel tank is all generally install near organism bottom engine, work under bad environment, vibrates larger.Therefore, the sealing property after sealed self-locking nut installation determines service behaviour and the security performance of complete machine.But all adopt on drilling machine in the production and processing of current a lot of sealed self-locking nut, carry out the mode of operation press-fited with simple frock, this mode of operation makes the flatness of the sealed self-locking nut seal closure bottom surface of producing poor, causes sealing property bad; Assembling height dimension uniformity is poor, and rework rate is high, wastes a lot of time, even produces some underproof product wastes and produces material, bring very large loss to enterprise.
Utility model content
For overcoming above-mentioned defect, the utility model provides a kind of assembling device processing sealed self-locking nut assembly on punch press.
An assembling device for sealed self-locking nut assembly, this assembling device comprises: die shoe, bottom plate, punch, lower bolster, cope match-plate pattern, upper bolster, die shank, locating pin, guide pin bushing, cylindroid helical-coil compression spring group, unloading bolt group; Described die shoe is positioned at the bottommost of whole assembling device; Bottom plate is fixed on die shoe; Described punch is fixed on the central part of die shoe through the center of bottom plate; Bottom plate, lower bolster are all sleeved on punch; Described cope match-plate pattern is fixed on upper bolster, and upper bolster is set with and is fixed on die shank; Locating pin is fixed on punch, is integrated with punch; Described guide pin bushing is sleeved on the outer surface of bottom plate, lower bolster; Cylindroid helical-coil compression spring group is made up of 3 cylindroid helical-coil compression springs; Unloading bolt group is made up of 3 unloading bolts; Cylindroid helical-coil compression spring is equal with the quantity of unloading bolt, and described cylindroid helical-coil compression spring is sleeved on unloading bolt; Cylindroid helical-coil compression spring and unloading bolt match between two and are fixed on uniformly on die shoe.
Mobile space is provided with between described bottom plate and lower bolster.
The utility model is by processing sealed self-locking nut assembly on punch press, compared with processing on drilling machine with tradition, it is good that the part processed has flatness, sealing property is good, Assembly of the parts dimensional uniformity is high, and processing efficiency is high, reduces the waste of some substandard product materials, the advantage such as save production cost, and can bring good benefit for enterprise.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
As shown in Figure 1, an assembling device for sealed self-locking nut assembly, this assembling device comprises: die shoe 1, bottom plate 2, punch 3, lower bolster 4, cope match-plate pattern 5, upper bolster 6, die shank 7, guide pin bushing 10, cylindroid helical-coil compression spring group 11, unloading bolt group 12 form.Die shoe 1 is positioned at the bottommost of whole assembling device, plays a supportive role.Bottom plate 2 is fixed by screws on die shoe 1.The center that punch 3 passes bottom plate 2 is fixed by screws in the central part of die shoe 1.Bottom plate 2, lower bolster 4 are all sleeved on punch 3.Cope match-plate pattern 5 is fixed on upper bolster 6 by screw and straight pin, and upper bolster 6 is set with and is fixed on die shank 7.Locating pin 9 is fixed on punch 3, is integrated with punch 3.Guide pin bushing 10 is sleeved on the outer surface of bottom plate 2, lower bolster 4, play the guiding role to cope match-plate pattern 5.Cylindroid helical-coil compression spring group 12 is made up of 3 cylindroid helical-coil compression springs; Unloading bolt group 13 is made up of 3 unloading bolts; Cylindroid helical-coil compression spring is equal with the quantity of unloading bolt, and cylindroid helical-coil compression spring is sleeved on unloading bolt.Cylindroid helical-coil compression spring and unloading bolt match between two and are fixed on uniformly on die shoe 1.
As shown in Figure 2, sealed self-locking nut assembly 8 seal closure 14, sealing ring 15, packing ring 16, self-locking nut 17 form.In sealed self-locking nut assembly 8, the guarantee of seal closure 14 mounting plane degree is realized by elastic blank holding device, and cylindroid helical-coil compression spring 12, unloading bolt 13 and lower bolster 4 form elastic blank holding and shedding mechanism jointly.In the effect of cylindroid helical-coil compression spring 12, upwards released by lower bolster 4, make locating pin 9 bottom surface lower than the certain distance of lower bolster 4, the locating pin 9 on punch 3 is inserted in packing ring 16 and self-locking nut 17.When patrix is descending, cope match-plate pattern 5 first touches seal closure 14, under spring force, cope match-plate pattern 5, seal closure 14 and lower bolster 4 are fitted completely, patrix continues descending, and make in packing ring 16 in locating pin 9 and self-locking nut 17 indentation sealing cover 14, patrix continues descending, until lower bolster 4 and bottom plate 2 are fitted completely, realize mounting plane leveling bottom seal closure.
The control of compression distance, by controlling the gauge of punch 3 height dimension and lower bolster 4, after lower bolster 4 is depressed into and fits completely with die shoe 1, locating pin 9 bottom surface on punch 3 can enter the fixing size of seal closure 14 bottom mounting surfaces one, be the size that packing ring 16 is pressed into, this press-in size is equal with the mobile space 11 between upper mounted plate 2 with lower bolster 4.Lower bolster 4 can slide up and down at the outer surface of punch 3.
The realization of material unloading function, when patrix is up, under the effect of cylindroid helical-coil compression spring 12, unloading bolt 13 promotes lower bolster 4 and moves upward, and the sealed self-locking nut assembly 8 after assembling is come off from punch 3.
The utility model eliminates the structural shape that conventional ones mould both sides guide pillar guide pin bushing carries out leading, use guide pin bushing 10 and bottom plate 2 instead, lower bolster 4, cope match-plate pattern 5 carry out cooperation and come adjustment assembly center, make this assembling device compacter, it is more convenient to process, and well solve the problem that seal closure mounting plane is uneven and packing ring setting height(from bottom) is inconsistent, make the product quality of sealed self-locking nut more reliable, production efficiency improves greatly.
Raw-material selection and Heat Treatment Control: in order to ensure the reliability of this device, to the raw material of vital part in device and the property indices that will reach, all made concrete requirement.Specific as follows:
(1) die shoe 1, bottom plate 2, upper bolster 6 and die shank 7 all adopt 45# Steel material, reach 32 ~ 36HRC through heat treatment, make it to bear larger impulsive force.
(2) punch 3, cope match-plate pattern 5 and lower bolster 4 adopt Cr12MoV, and reach 52 ~ 56HRC through heat treatment, make it to have stronger abrasion resistance properties.
The utility model assembling device has the following advantages:
(1) employing is processed on punch press, and production efficiency improves greatly;
(2) elastic blank holding device is adopted to make mounting plane smooth;
(3) cope match-plate pattern and location punch dimensionally stable, the depth consistency that packing ring is pressed into is guaranteed.
