Detailed Description

Referring to fig. 1, the present application provides a technical solution: the utility model provides an automobile rear axle sleeve pipe extracting tool, includes positioning iron 1, and the pull rod 2 is installed in positioning iron 1's inside rotation, and positioning iron 1's surface is equipped with locking device 3, and positioning iron 1's surface is equipped with strutting arrangement 4.

The specific arrangement and function of the locker 3 and the supporting device 4 will be described in detail below.

Referring to fig. 2 and 3 and fig. 4, in the present embodiment: locking device 3 includes reserve chamber 33, reserves the inside at pull rod 2 of chamber 33 division, and the inner wall sliding connection who reserves chamber 33 has inserted bar 31, and first jack 34 has been seted up on the surface of location iron 1, and the size of first jack 34 on the location iron 1 and the size looks adaptation of inserted bar 31. The inside inserted bar 31 of twitch pull rod 2 is fixing a position the back in putting into the sleeve pipe with location iron 1, when inserted bar 31 rotate to and the locating lever between be the position of vertical angle, insert the inner wall at first jack 34 with inserted bar 31, realized the quick hasp work to rotation back pull rod 2 and location iron 1, improved the stability after location iron 1 and pull rod 2 rotate.

The outer circumferential surface of the insert rod 31, which is positioned on the inner wall of the positioning cavity of the pull rod 2, is fixedly connected with a ring 37, the surface of the insert rod 31 is sleeved with a spring 38, and two ends of the spring 38 are respectively fixedly connected with the ring 37 and the inner wall of the pull rod 2. The insert rod 31 is inserted into the inner wall of the first insert hole 34 by the elastic force of the spring 38 between the pre-chamber 33 and the ring 37 of the pull rod 2. The end face of the insertion rod 31 is fixedly connected with an auxiliary block 35, and the auxiliary block 35 is in a circular truncated cone-shaped structure. The auxiliary block 35 with the circular truncated cone-shaped structure facilitates quick clamping between the opposite insertion rod 31 and the first insertion hole 34, and further improves the efficiency of clamping between the opposite pull rod 2 and the positioning iron 1.

The surface of the positioning iron 1 is fixedly connected with a positioning block 32, and the surface of the positioning block 32 is provided with a second jack 36. The insertion rod 31 is inserted into the inner wall of the second insertion hole 36 on the positioning block 32, so that the clamping work between the positioning iron 1 and the pull rod 2 in a horizontal state is facilitated, the situation that the positioning iron 1 penetrates into the sleeve and rubs with the inner wall of the sleeve is reduced, and the use safety of the disassembling tool is improved.

Referring to fig. 2, 3 and 5, specifically, the supporting device 4 includes a rectangular hole 43, the rectangular hole 43 is opened on the surface of the positioning iron 1, two limiting bars 41 are slidably connected to the inner wall of the rectangular hole 43 on the positioning iron 1, two supporting rods 42 are fixedly connected to the surface of the limiting bars 41, and the supporting rods 42 are slidably connected to the inside of the positioning iron 1. The rotating block 47 drives the driving rod 46 to rotate in the fixing frame 45, so that the limiting strips 41 are driven on the inner wall of the rectangular hole 43, and the distance between the two limiting strips 41 can be adjusted. Two fixing frames 45 are fixedly connected to the side wall of the positioning iron 1, a driving rod 46 is inserted into the internal thread of the fixing frame 45, the driving rod 46 is rotatably connected with the inside of the limiting strip 41, and a rotating block 47 is fixedly connected to one end, far away from the limiting strip 41, of the driving rod 46. The rotating block 47 is rotated, and the rotating block 47 drives the driving rod 46 to rotate inside the fixing frame 45.

One end of the support rod 42 away from the position-limiting bar 41 is glued with an elastic block 44, and the elastic block 44 is in a hemispherical structure. The elastic block 44 with the hemispherical structure is supported on the inner wall of the sleeve, so that the stability of the positioning iron 1 supported on the inner wall of the sleeve is further improved.

The working principle is as follows: the inside inserted bar 31 of twitch pull rod 2, after putting into the sleeve pipe location with positioning iron 1, when inserted bar 31 rotates to and is the position of vertical angle between the locating lever, loosen inserted bar 31, inserted bar 31 can receive spring 38 elastic force effect and insert the inner wall at first jack 34 between reserved chamber 33 and ring 37 on the pull rod 2 this moment, realized the quick hasp work to pull rod 2 and positioning iron 1 after rotating, the stability after positioning iron 1 and pull rod 2 rotate has been improved, the auxiliary block 35 of round platform column structure has made things convenient for the quick joint between inserted bar 31 and first jack 34, the efficiency of the buckle between pull rod 2 and positioning iron 1 has further been improved, through setting up locking device 3, the hasp work after having made things convenient for rotating perpendicularly between positioning iron 1 and the pull rod 2, the stability between positioning iron 1 and the pull rod 2 after having improved to rotate has been reduced and has been connected for rotating between positioning iron 1 and the pull rod 2, the condition that the user appears easily between positioning iron 1 and the pull rod 2 in the process of strikeing the pull rod, the dismouting efficiency of the sleeve pipe has been improved as far as possible.

The insertion rod 31 is inserted into the inner wall of the second insertion hole 36 on the positioning block 32, so that the clamping work between the positioning iron 1 and the pull rod 2 in a horizontal state is facilitated, the situation that the positioning iron 1 deeply penetrates into the sleeve and rubs with the inner wall of the sleeve is reduced, and the use safety of the dismounting tool is improved.

When the work is dismantled to the sleeve pipe of equidimension not in needs, rotatable commentaries on classics piece 47, commentaries on classics piece 47 can drive actuating lever 46 and rotate at the inside of mount 45, thereby realized the drive to spacing 41 at rectangular hole 43 inner wall, can realize the regulation of distance between two spacing 41 this moment, make four bracing pieces 42 support at the sheathed tube inner wall of equidimension structure not, thereby made things convenient for the work of dismantling not equidimension structure sheathed tube, hemispherical structure's elastic block 44 supports at the sheathed tube inner wall, further improved the stability that positioning iron 1 supported at the sheathed tube inner wall, through setting up strutting arrangement 4, the regulation to distance between four bracing pieces 42 has been made things convenient for, thereby made things convenient for the work of dismantling not support of equidimension structure positioning iron 1.
