Abstract
The utility model provides a novel ejector, which is provided with a screw rod connected with a central inner screw hole of an adjusting support body. The adjusting support body is provided with a support groove and a movable groove. The bent foot is embedded in the movable groove, the upper supporting pin of the bent foot is embedded in the supporting groove, the external thread of the adjusting supporting body is connected with the adjusting nut, the opening degree of the bent foot can be quickly and conveniently adjusted by rotating the adjusting nut, the puller not only can be used for independently carrying out inner diameter jacking and pulling or outer diameter jacking and pulling, but also can be used for jacking and pulling parts without internal support by serially connecting two jacks by using a screw rod, and therefore, the puller has wide application range.
Description
The utility model relates to extracting tool.The thruster of one class novelty is provided.
Thruster can be described as again and draws horse, drag hook, bearing to trip out device etc.It is mainly used in bearing, gear, belt pulley and the various turning cylinder fixture that dismounting is assembled very tightly.The parts that adopt thruster dismounting axle sleeve class to cooperate with the hole.Not only can be laborsaving, and can not damage parts.Therefore, thruster is widely used in departments such as machine maintenance, installation, electrician.China Ministry of Machine-Building Industry has issued ministry standard JB3460～83 liang pawl thruster and JB3461～83 three-jaw thrusters December nineteen eighty-three.But the diameter of pulling of three-jaw thruster is regulated comparatively effort.Clubfoot is changed difficulty, and above-mentioned two kinds of thrusters are being helpless aspect the axle sleeve type component of the no internal support of dismounting.Under the situation of no internal support, the screw rod of thruster is top can not to hold out against stressedly, causes the thruster cisco unity malfunction, can't solve this class difficult problem that often runs in the maintenance work.
The purpose of this utility model provides the thruster of a class novelty, and it is easy to adjust to pull diameter, and clubfoot is easy to change, and the further purpose of the utility model provides the thruster that a class also can be used under no internal support situation.
Task of the present utility model is achieved through the following technical solutions.
Thruster described in the utility model has a screw rod, be characterized in the adjusting supporting mass, the center inner bolt hole of regulating supporting mass cooperates connection with screw rod, regulate on the supporting mass and have support slot and loose slot, clubfoot embeds in loose slot, fulcrum post on the clubfoot embeds in support slot, and external screw thread and the adjusting nut regulated on the supporting mass are thread connection.
The utility model clubfoot of being mounted on the thruster of design preferably can be two, three or many, constitutes two pawls, three-jaw or multijaw thruster, clubfoot or outer clubfoot in clubfoot can be made into.
The better design of the utility model is that the spring of eliminating the gap is installed in the bottom of loose slot.
The best design of the utility model is that two thrusters are cascaded with a screw rod.
With reference to the accompanying drawings the utility model is done detailed description below.

With reference to Fig. 1～10, thruster described in the utility model has a screw rod (1), and the center inner bolt hole (3) of regulating supporting mass (2) connects with screw rod (1) matching thread.On adjusting supporting mass (2), have support slot (4) and loose slot (5), the garden segmental arc on clubfoot (6) top embeds in loose slot (5), fulcrum post (7) on the clubfoot (6) embeds in support slot (4), and the external screw thread of regulating on the supporting mass (8) is equipped with the spring (10) of eliminating the gap with adjusting nut (9) thread connection, in the bottom of loose slot (5); The clubfoot that is installed in as required on the thruster can be two, three or many, only needs to leave the loose slot (5) that equates with the clubfoot quantity of being installed on adjusting supporting mass (2) and gets final product, and can produce two pawl three-jaws or multijaw thruster easily; Clubfoot (6) can manufacture interior clubfoot (11) and outer clubfoot (12) as required, thus, and clubfoot thruster and outer clubfoot thruster in can producing; Thruster shown in Figure 1 is one of best embodiment of the present utility model, it is that two thrusters are cascaded with a screw rod, the thruster of this structure can be conveniently used for dismantling the axle sleeve type component of no internal support, has increased the scope of application of thruster greatly.
The operation principle and the using method of thruster described in the utility model are as follows: rotation adjusting nut (9) can be regulated the opening width of clubfoot (6) quickly and easily and be disassembled the parts fit, catches lower surface or other supporting-point that is disassembled parts with the claw hook of clubfoot.Handle (13) on the rotary screw (1) makes the top internal support that withstands of screw rod, and force the adjusting supporting mass (2) that has the center internal thread to move axially, drive clubfoot (6) by regulating supporting mass (2), clubfoot (6) drives and is disassembled parts it is disassembled reposefully.The parts of the no internal support of dismounting should adopt thruster shown in Figure 1 if desired.This thruster utilizes the clubfoot of clubfoot thruster outside the top to withstand to be disassembled the supporting end face of parts outside to constitute external support.The opening width of clubfoot by the adjusting nut adjustment to be fit to needs.Utilize the clubfoot of the interior clubfoot thruster of bottom to catch the lower surface that is disassembled parts, handle (13) on the rotary screw (1) then, the upper end that makes clubfoot thruster outside the top withstand screw rod does not remake axially-movable, and force in the bottom clubfoot thruster to continue to move axially, be disassembled parts by the clubfoot drive it is disassembled reposefully.
Adopt the advantage of thruster described in the utility model to be: (1) can adjust the opening width of clubfoot very easily, adapts to parts are namely pulled diameter to the clubfoot opening width the different needs that is disassembled of different-diameter; (2) change the clubfoot simple procedure, the same base part of thruster has interchangeability, and is easy to use, maintenance, and produce; (3) can use separately interior clubfoot thruster to carry out internal diameter pulls, also the laggard row external diameter of replaceable outer clubfoot is pulled: (4) the most outstanding advantage is to adopt the thruster of series connection can finish the pulling of the parts of no internal support, and particularly removes close-fitting parts in the hole.
Claims (3)
1, thruster, a screw rod (1) is arranged, it is characterized in that having adjusting supporting mass (2), the center inner bolt hole (3) of regulating supporting mass (2) cooperates connection with screw rod (1), on adjusting supporting mass (2), have support slot (4) and loose slot (5), clubfoot (6) embeds in loose slot (5), fulcrum post (7) on the clubfoot (6) embeds in support slot (4), the external screw thread of regulating on the supporting mass (2) (8) is a thread connection with adjusting nut (9), and two thrusters are cascaded with a screw rod (1).
2, thruster according to claim 1, the clubfoot (6) that it is characterized in that being installed on the thruster can be two, three or many.Clubfoot (6) can be made into interior clubfoot (11) or outer clubfoot (12).
