Abstract
The utility model discloses an internal expanding impulse type puller, and belongs to a valve core demounting tool. The puller is provided with a pull rod, wherein an internal thread hole is opened at one end of the pull rod, and a handle is arranged at the other end of the pull rod; a frog capable of axially sliding along the pull rod is installed on the pull rod; an expansion head is installed at the end, at which the internal thread hole is opened, of the pull rod; the expansion head comprises a hexagonal nut, a connector fixed on the end surface of the hexagonal nut and four claws which are uniformly and symmetrically arranged on the end surface of the connector; a thread hole identical to the hexagonal nut is opened at the center of the connector; each claw adopts an internal-taper-shaped elastic sheet, and the wider end of the internal-taper-shaped elastic sheet is installed on the end surface of the connector; a cone-point screw is connected between the expansion head and the internal thread hole; the cone-point screw is inserted into the internal thread hole after penetrating the connector and the hexagonal nut; and the outer end of the frog is provided with a clamping groove matched with the hexagonal nut. The internal expanding impulse type puller disclosed by the utility model has the advantages of simplicity and practicality, convenience for operation, no damage to parts, and high demounting efficiency under the condition of multiple parts.
Description
Technical field
The utility model relates to dismounting spool instrument, specifically is a kind of internal expanding impact type drawbench, mainly is applicable to the spool dismounting of aluminum cold-rolling mill segmentation cooling jet beam; Also be installed in the blind hole, the findings such as bearing of the internal diameter ￠ 8--￠ 9 of endoporus are arranged applicable to pulling out.
Background technology
162 nozzle spools in the cold-rolling mill jet beam need often split out inspection and clean, and some findings that are installed in the band endoporus in the blind hole split out inconvenience.Existing instrument removes trouble, and effect is bad, through regular meeting's damage threshold core and part.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of internal expanding impact type drawbench, but the spool of conveniently fast disassembling aluminum cold-rolling mill segmentation cooling jet beam be installed in the parts such as little bearing in the blind hole.
The utility model is realized with following technical scheme: a kind of internal expanding impact type drawbench, comprise a pull bar, and an end of pull bar has internal thread hole, and the other end is provided with handle; On pull bar, install one and can hit iron in axial sliding along pull bar; That end that has internal thread hole on the pull bar is equipped with the head that rises; The described head that rises comprises hexagonal (hexagon)nut, is fixed on connector and 4 claws that are arranged on symmetrically on the connector end face on the hexagonal (hexagon)nut end face; The connector center has the screwed hole the same with hexagonal (hexagon)nut; Described claw adopts internal taper shape shell fragment, and that end of internal taper shape shell fragment broad is installed on the end face of connector; Rise the head with internal thread hole between be connected a cone-head screw; Cone-head screw passes connector and hexagonal (hexagon)nut inserts in the internal thread hole; Described outer end of hitting iron is provided with the draw-in groove that matches with hexagonal (hexagon)nut.
The beneficial effect of the utility model: simple and practical, easy to operate; Under the part situation how, removal efficiency is high.

Among the figure: 1, cone-head screw, 2, the head that rises, 21, hexagonal (hexagon)nut, 22, connector, 23, claw, 3, pull bar, 31, internal thread hole, 4, hit iron, 41, draw-in groove, 5, handle.
The specific embodiment
As depicted in figs. 1 and 2, a kind of internal expanding impact type drawbench has a pull bar 3, and an end of pull bar 3 has internal thread hole 31, and the other end is provided with handle 5; On pull bar 3, install one and can hit iron 4 in axial sliding along pull bar 3; That end that on pull bar, has internal thread hole is equipped with and rises 2; Rise and 2 be installed in the head of pull bar through cone-head screw 1.
Shown in Fig. 3～5, rising 2 comprises hexagonal (hexagon)nut 21, is fixed on connector 22 and 4 claws 23 that are arranged on symmetrically on connector 22 end faces on hexagonal (hexagon)nut 21 end faces; Connector 22 centers have the screwed hole the same with hexagonal (hexagon)nut; Described claw 23 adopts internal taper shape shell fragment, and that end of internal taper shape shell fragment broad is installed on the end face of connector 22; Rise 2 with internal thread hole 31 between be connected a cone-head screw 1; Cone-head screw 1 passes connector 22 and inserts in the internal thread hole 31 with hexagonal (hexagon)nut 21.
Like Fig. 6 and shown in Figure 7, hit iron 4 the center have through hole, hit iron 4 and be installed on the pull bar 3 through through hole; The outer end of hitting iron 4 is provided with the draw-in groove 41 that matches with hexagonal (hexagon)nut 21.
The course of work: 2 the head of will rising inserts in the endoporus, hits iron 4 and slides into 2 the rear portion of rising, and the draw-in groove 41 that hand will hit on iron 4 end faces blocks on the hexagonal (hexagon)nut 21 of the head that rises; Fixedly rise and 2 can not rotate, the handle 5 that another holds pull bar turns pull bar 3 clockwise, and the cone-head screw in 2 of rising this moment is then toward the internal thread hole precession of 3 li on pull bar; Four claws that drive on the connector 22 open; Claw 23 has just propped up the part endoporus, and it is motionless to hold handle, and light slip of another have gentle hands hit iron 4; Make the handle 5 at the rear portion of its bump pull bar, spool or little bearing just have been drawn out.Then, turn pull bar counterclockwise, cone-head screw screws out, the claw withdrawal, and part can be taken down from the head that rises.
If strengthen the size of drawbench, the utility model also can be dismantled the big part of internal diameter.
