Description
Technical field
The utility model belongs to a kind of machine tool, particularly a kind of pulley extractor.
Background technology
In plant equipment, the tumbler in the rotating shaft such as belt pulley or gear etc. need to change in use for some time.Owing to usually can get rusty between tumbler and the rotating shaft, if therefore be not difficult to extract by means of specific purpose tool.The locking type pulley extractor is exactly the specific purpose tool that occurs in this case.Common locking type pulley extractor comprises push rod, is socketed in screw mandrel and jaw seat on the push rod, and several jaws are arranged on the jaw seat, also has a jack unit on the push rod.During use, catch the tumbler that will extract with jaw, and the push rod roof pressure in rotating shaft, utilize jack unit to make the rotating shaft of push rod roof pressure then, thereby jaw produces the outwards pulling force of pulling tumbler, at last tumbler is pulled out.In common this locking type pulley extractor, because jaw is hinged with the jaw seat, clamp tumbler to push rod is applied in the process of roof pressure power at jaw, obscission appears in jaw easily, cause and operate trouble when using, directly influence the normal use of pulley extractor.
Summary of the invention
The purpose of this utility model is in order to solve the problem that the existing jaw of present locking type pulley extractor comes off easily, a kind of structure improved locking type pulley extractor to be provided, its jaw in use can not being come off.
The purpose of this utility model realizes by following technical proposal: this locking type pulley extractor comprises the jack unit on push rod, the push rod and is socketed in screw mandrel on the push rod, the front end of the screw mandrel jaw seat that is being connected, several and the hinged jaw of jaw seat are set on the jaw seat, locating rack of socket on the screw mandrel, the locating rack front portion is the fence of a sealing, the tail end of locating rack is provided with a retaining ring, and the retaining ring connects with screw mandrel by screw thread.
Above-mentioned jack unit comprises the nut of push rod afterbody, and nut is fixed on the push rod, passes through thread connection between push rod and the screw mandrel.Instrumental purposes such as use spanner reverse push rod on nut, just can make the push rod roof pressure in rotating shaft.
In addition, jack unit also can be made up of the hydraulic part in hydraulic cylinder, oil pipe and the hydraulic cylinder, and hydraulic cylinder is fixed in the screw mandrel, and push rod and hydraulic part are fixed together.Utilize hydraulic principle, can reach the purpose of roof pressure equally.
Above-mentioned fence is provided with and the corresponding recess of jaw equal number and position.
Usually the quantity of jaw is three, and three corresponding recesses are correspondingly also arranged on the fence of locating rack.
When this locking type pulley extractor uses, at first catch the tumbler that to extract with jaw; Push ahead locating rack then, make the jaw location by fence; Then rotate the retaining ring forward, thereby locating rack and jaw all obtain the location; At last, utilize the jack unit of push rod afterbody to make the push rod roof pressure in rotating shaft, jaw produces outside pulling force, and tumbler is extracted.
Compare with existing locking type pulley extractor, the utility model is owing to set up locating rack and retaining ring, and jaw can not come off when making pulley extractor work, and is easy to operate, improved the stability and the operating efficiency of pulley extractor.
Description of drawings

Fig. 2 is the cutaway view of the locking type pulley extractor that provides of the utility model.
Fig. 3 is the profile schematic diagram of locating rack in the locking type pulley extractor that provides of the utility model.
The specific embodiment
As depicted in figs. 1 and 2, the locking type pulley extractor that present embodiment provides is a kind of pulley extractor with mechanical jack unit, and it comprises parts such as push rod 1, screw mandrel 2, locating rack 3, jaw seat 4, retaining ring 5, jaw 6 and nut 7.Screw mandrel 2 is socketed on the push rod 1, passes through thread connection between screw mandrel 2 and the push rod 1.The tail end of push rod 1 nut 7 that is being connected.Jaw seat 4 is fixed in screw mandrel 2 outsides.In the present embodiment, three jaws 6 are set on the jaw seat 4, jaw 6 is hinged with jaw seat 4.
As depicted in figs. 1 and 2, locating rack 3 is placed on the screw mandrel 2.The profile of locating rack 3 as shown in Figure 3.The front portion of locating rack 3 is a fence 30, and three recesses 31 are arranged on the fence 30.Article three, jaw 6 lays respectively in these three recesses 31.In the present embodiment, the sidepiece of jaw 6 also is provided with convex tendon 60.60 barrier effects of convex tendon make jaw 6 be positioned at recess 31 all the time.Obviously, because jaw seat 4 is fixed on the screw mandrel 2, and hinged with jaw 6, so jaw 6 can shrink or open along with moving forward and backward of locating rack 3, and is very convenient during operation.The retaining ring 5 of locating rack 3 afterbodys connects with screw mandrel 2 by screw thread, 5 position-limiting actions of retaining ring.In case after jaw 6 is clamped tumbler, tighten retaining ring 5 forward, can prevent that locating rack 3 from retreating, jaw 6 just can not ease out like this.
