The technical solution of the utility model is:
A kind of pull rod bearing quickly exchanges device for, and the present apparatus includes handle and the frame that is fixedly connected with handle, the frame
The arranged on left and right sides of frame is coaxially arranged with propulsion device and pressurizing unit respectively, and the propulsion device is by push bolt and bolt sleeve
Composition is equipped with mutually matched screw thread on the periphery of push bolt and the inner circumferential of bolt sleeve；The pressurizing unit by apical axis with
Apical axis set composition, the apical axis front end are equipped with extrusion head, and rear end and inner hole of shaft sleeve cooperation position, and the apical axis, which is put on, to be equipped with and squeeze
The mutually matched fixing groove of pressure head, top end face of shaft bush are equipped with the positioning step for steady brace bearing axle sleeve.
The bolt sleeve is fixed-type by welding manner with frame left.
The apical axis set and frame right are fixed-type by welding manner.
The push bolt end face is equipped with convex cone, and the extrusion head is equipped with the fixation hole to match with the convex cone.
The beneficial effects of the utility model are:
The utility model is mainly constituted by exchanging propulsion device and pressurizing unit coaxially arranged on device frame for, described to push away
It is made of into device push bolt and bolt sleeve, mutually matched spiral shell is equipped on the periphery of push bolt and the inner circumferential of bolt sleeve
Line；The pressurizing unit is made of apical axis and apical axis set, and the apical axis front end is equipped with extrusion head, and rear end and inner hole of shaft sleeve cooperation are fixed
Position, the apical axis put on to be equipped with and be equipped with the mutually matched fixing groove of extrusion head, top end face of shaft bush for steady brace bearing
The positioning step of axle sleeve.The utility model to pull rod bearing to exchange difficulty for small, other components damages are reduced when exchanging bearing for,
Requirement to people maintenance personal reduces.

Specific embodiment
The utility model is that a kind of pull rod bearing quickly exchanges device for, shown in Fig. 1, is mainly used to exchange for and is socketed in pull rod 14
Interior bearing 12, the present apparatus include handle 1 and the frame being fixedly connected with handle 2, and 2 profile of frame is a rectangle, frame
Size can be determined according to the working space of installation pull rod bearing.
It is equipped with propulsion device in the left side of frame 2, right side is equipped with pressurizing unit, and propulsion device and pressurizing unit are on frame
It is arranged along same axis, wherein propulsion device is made of push bolt 3 and bolt sleeve 4, and bolt sleeve 4 is fixed by welding manner
It in the left side of frame, can also be integrally formed, the inner peripheral surface of bolt sleeve is equipped with internal screw thread；The outer peripheral surface of push bolt 3 is equipped with
External screw thread, the screw-internal thread fit with bolt sleeve, 3 tail portion of push bolt can connect the nut for helping to screw, and promote spiral shell
On the front end face of bolt, it is equipped with a convex cone 5.Wherein pressurizing unit is made of an apical axis 6 and an apical axis set 7, apical axis set
It is fixed on frame right by welding manner, can also be integrally formed with frame, apical axis is put on equipped with a fixing groove 10, this is solid
Determining slot is circular groove, is equipped with a through-hole at the rear of fixing groove, which is connected to fixed slot tail, and the other end passes through
Wear apical axis set.On the front end face of apical axis set, it is additionally provided with a positioning step 11, which is used for and exchanged for bearing
