Abstract

The ball head detacher is a maintenance tool of an automobile steering mechanism, and comprises a cylindrical detacher body and a bolt mandril spirally connected with a center hole of the upper bottom surface of the detacher body, wherein the side surface and the lower bottom surface of the detacher body are provided with an axial hole inlet groove and a radial neck inlet groove which are communicated, the width of the hole inlet groove is greater than that of the neck inlet groove, two side support hooks are formed on the lower bottom surface of the detacher body, and the lower bottom end of the detacher body is in an inclined plane concave shape which is in the same direction as. The detacher can be used for detaching pull rod bulbs and wiper rocker arms of various automobiles, and is convenient to use, labor-saving and safe.

Description

Bulb disassembling device

The utility model relates to a kind of service tools of automotive steering structure, particularly the bulb stripper.

In automotive steering structure, bulb works to connect rocking arm and straight and horizontal adjusting rod is coordinated to turn to.Be the tight socket of journal hole of tapering on ball head neck and the rocking arm, bulb axle journal end is a binding bolt.Still the special tool that does not have at present the dismounting bulb, and the Motor Maintenance maintenance often needs the dismounting bulb.Because rocking arm, pull bar etc. are installed in the space that the wheel inboard is very narrow under the frame beam, only expose the bulb axle journal of 3 to 4 millimeters height in rocking arm and the slit, pull bar junction, again owing to rocking arm, pull bar all are unsettled works done, the bulb axle journal connecting bridge corrosion of easily intaking in addition, therefore it is very difficult to dismantle bulb, vehicle propons jack-up be fallen tire down, withstand rocking arm, pound with the hammer skid plate, easily the bulb screw thread is smashed, repair rate is low, also may injure staff by a crashing object, effort, bothersome.

The purpose of this utility model is that the bulb stripper that provides a kind of energy to dismantle bulb is exempted the hard work of existing dismounting mode convenient and strength-savingly.

Composition of the present utility model comprises cylindrical dismounting body and bolt push rod, the bolt push rod is connected with dismounting body upper bottom surface centre hole spiral, dismounting body side surface and bottom surface have axially advancing hole slot and radially advancing the neck groove of connection, advance the hole slot width greater than advancing the neck well width, form the both sides hook at dismounting body bottom surface, bottom face is and advances neck groove inclined-plane indent in the same way under the dismounting body.

Below in conjunction with embodiment and with reference to accompanying drawing the utility model is described in detail.

Fig. 1 is the utility model embodiment schematic perspective view.

Fig. 2 is the utility model embodiment front view.

Fig. 3 is the utility model running condition scheme drawing.

As depicted in figs. 1 and 2, composition of the present utility model comprises cylindrical dismounting body 3 and bolt push rod 1, the bolt push rod is connected with dismounting body 3 upper bottom surface centre holes 2 spirals, dismounting body 3 sides and bottom surface have axially advancing hole slot 4 and radially advancing neck groove 5 of connection, advance hole slot 4 width greater than advancing neck groove 5 width, form both sides hook 6 at dismounting body bottom surface, bottom face is and advances neck groove 5 inclined-plane indent in the same way under the dismounting body, in this embodiment, dismounting body lower surface is the cambered surface indent.The oblique indent design of bottom face under the dismounting body, can make both sides hook 6 put in bulb axle journal between rocking arm (among Fig. 3 shown in 7) and the pull bar (among Fig. 3 shown in 11) (among Fig. 3 shown in 10) slit, hold bulb journal hole on the rocking arm (among Fig. 3 shown in 9), can make dismounting body bottom surface have enough rising again and hold in the palm intensity, when dismounting body bottom surface is the cambered surface indent, play holder intensity maximum, and hook shape and ball head neck gap space match most.Among the embodiment, bottom face has certain tapering on the dismounting body 3, be for has guaranteed holder intensity and with the prerequisite of bolt push rod spiral Joint strenght under reduce and dismantle the body rolled steel dosage, alleviate stripper weight and reduce the space that stripper occupies.

As shown in Figure 3, be the journal hole 9 tight sockets of tapering on bulb axle journal 10 and the rocking arm 7,8 is the bulb binding bolt, and bulb (not drawing among the figure) is contained in the pull bar 11.When needing the dismounting bulb, as long as ball stud cap (not drawing among the figure) is backed out, the dismounting body 3 of the utility model stripper is set on the bulb journal hole 9 from advancing hole slot 4 and advancing neck groove 5, the dismounting body both sides hook 6 of going to the bottom stretches between rocking arm 7 and the pull bar 11 in bulb axle journal 10 slits, and stably hold journal hole 9 bottoms, twist stripper bolt push rod 1 with wrench, make it the lower end and bulb binding bolt 8 holds out against, because bolt push rod 1 is connected with dismounting body 3 upper base centre holes 2 spirals, dismantle the effect national power that body is subjected to upward movement this moment, just journal hole 9 is held up, reach the purpose of pulling down bulb.The utility model dismounting body and function steel are manufactured, can the unit-cast unit moulding, and the cutting thread of holing again, complete in specifications, easy to use, laborsaving, safety significantly improves work efficiency, can be used for dismantling the tie rod ball and the wiper rocking arm of various automobiles.

Claims

1, a kind of bulb stripper that is used for the automotive steering structure maintenance, it is characterized in that forming and comprise cylindrical dismounting body and bolt push rod, the bolt push rod is connected with dismounting body upper bottom surface centre hole spiral, dismounting body side surface and bottom surface have axially advancing hole slot and radially advancing the neck groove of connection, advance the hole slot width greater than advancing the neck well width, form the both sides hook at dismounting body bottom surface, dismounting body lower surface is and advances neck groove inclined-plane indent in the same way.

2, bulb stripper according to claim 1 is characterized in that dismantling that bottom face has tapering on the body.
