Technical field
The utility model relates to a kind of process unit of heat treatment of workpieces, and particularly one is used for the heat treated endoporus seal protecting device of piston rod, belongs to Machining Technology field.
Background technology
Piston rod is one of important moving parts of high-powered low-speed marine diesel engines, its length is longer, deep hole aperture is larger, after roughing, shaft surface needs to carry out special thermal treatment, in treating processes, whole piston rod all will enter process furnace heating, therefore the deep hole hole wall after heat treatment process on rod member certainly will easily be oxidized, variable color, huge workload is brought to follow-up pincers worker finishing, the polishing of deep hole hole wall is not only time-consuming but also require great effort, and deep hole hole wall is oxidized, variable color is the key point improving working (machining) efficiency therefore to adopt suitable means and instrument to prevent.
Utility model content
The purpose of this utility model is; there is provided a kind of for the heat treated endoporus seal protecting device of piston rod; solve the problem of piston rod endoporus inner wall oxide, variable color in heat treatment process; to reduce follow-up a large amount of manual polishing workload, reach reduce costs, improve work efficiency, reduce labour intensity, easy and simple to handle and ensure the effect of quality product.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
A kind of for the heat treated endoporus seal protecting device of piston rod, be placed in the endoporus of described piston rod, it is characterized in that: described protector comprises taper cock body, heat-resisting cotton layer, heat-resisting cotton circle, back up pad and joint bolt, described heat-resisting cotton layer is folded between described taper cock body and back up pad, back up pad described in the conical surface subtend of this taper cock body, described heat-resisting cotton snare is placed in the periphery of described heat-resisting cotton layer and is folded between described taper cock body and back up pad, this heat-resisting cotton circle side Da is placed on the conical surface of described taper cock body, opposite side overhead is in described back up pad, described joint bolt is through described back up pad and heat-resisting cotton layer and be threaded connection on described taper cock body, this joint bolt is by screwing this heat-resisting cotton layer of extruding and heat-resisting cotton circle outwards expands and seals the endoporus of described piston rod.
As further improvement, described taper cock body offers through pressure-releasing hole.
As further improvement, described back up pad offers through pressure-releasing hole.
The beneficial effects of the utility model are; before piston rod thermal treatment; described seal protecting device is arranged on the aperture place in the endoporus of piston rod; and by screwing joint bolt; make heat-resisting cotton layer and heat-resisting cotton circle spreading; extrude the inwall of endoporus; the endoporus of piston rod is sealed; thus avoid endoporus to be oxidized and variable color in heat treated heat-processed; ensure the intact of hole wall, the object of reach and effectively protect hole wall, reduce follow-up work amount, improve work efficiency, reduce labour intensity and guarantee quality product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure,
1-taper cock body, 11-pressure-releasing hole, 21-heat-resisting cotton layer, 22-heat-resisting cotton circle, 3-back up pad, 31-pressure-releasing hole, 4-joint bolt.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but protection domain of the present utility model can not be limited with this.
As shown in Figure 1; the described aperture place be placed in for piston rod heat treated endoporus seal protecting device in the endoporus A of described piston rod, this protector comprise taper cock body 1, heat-resisting cotton layer 21, heat-resisting cotton circle 22, in order to support back up pad 3 and the joint bolt 4 for being connected adjustment.
Described heat-resisting cotton layer 21 is folded between described taper cock body 1 and back up pad 3, back up pad 3 described in the conical surface subtend of this taper cock body 1.Described heat-resisting cotton circle 22 is placed on the periphery of described heat-resisting cotton layer 21, and is folded between described taper cock body 1 and back up pad 3, and this heat-resisting cotton circle 22 side Da are placed on the conical surface of described taper cock body 1, and opposite side overhead is on the medial surface of described back up pad 3.Described heat-resisting cotton layer 21 and heat-resisting cotton circle 22 can bear the high temperature of thermal treatment heating.Offer the pressure-releasing hole 11 and 31 of through part body in a thickness direction on described taper cock body 1 and in back up pad 3 respectively, release of pressure can be carried out when heating, reaching the gas pressure balancing inside and outside endoporus A.
Described joint bolt 4 passes the through hole of described back up pad 3 and heat-resisting cotton layer 21 central authorities; and be threaded connection on described taper cock body 1; this joint bolt 1 is by screwing the described heat-resisting cotton layer 21 of extruding and heat-resisting cotton circle 22 outwards expands; seal up the endoporus A of described piston rod; reach and outer isolated effect; prevent from heating the oxidation stain causing endoporus A hole wall, also can completely cut off in trickle foreign material access aperture, play the effect of protection hole wall.
Working process of the present utility model is as follows:
Before piston rod thermal treatment, described protector is placed in the aperture place in the endoporus A of piston rod, joint bolt 4 is screwed with instrument, make it to drive taper cock body 1, enclose 22 by taper cock body 1 and back up pad 3 to heat-resisting cotton layer 21 and heat-resisting cotton to extrude, the side of heat-resisting cotton circle 22 is moved along the conical surface of taper cock body 1 and outwards expands (see Fig. 1), simultaneously heat-resisting cotton layer 21 is also extruded and expands to periphery and to promote heat-resistingly cottonly to enclose the inwall that 22 outwards extrude endoporus A, thus the endoporus A of piston rod is sealed, the oxidation stain of endoporus A hole wall can not only be prevented, and can completely cut off in trickle foreign material access aperture, what ensure in hole is clean and tidy, reach the effect of seal protection endoporus hole wall.Piston rod is in stove in heat-processed, and hole external and internal pressure carries out release of pressure, to reach the gas pressure balancing inside and outside hole by the release of pressure aperture 11 and 31 on taper cock body 1 and back up pad 3.
The utility model can be high temperature resistant and increased substantially Product processing efficiency, and the fairly simple convenience of on-the-spot actually operating, significantly reduces labour intensity in addition, while guarantee production safety and quality product, improve efficiency.
Above-mentioned case study on implementation is not used for limiting scope of the present utility model; the protection domain that the utility model requires is not limited only to above-mentioned case study on implementation; also should be comprised other to the apparent conversion of the utility model and replacement scheme; all equivalences made according to content of the present utility model change and amendment, all belong to category of the present utility model.
