Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
A half shaft quick dismounting tool comprises a connecting rod 1, wherein a baffle disc 2 is fixed at one end of the connecting rod 1, a columnar clamping sleeve 3 used for being clamped and fixed at the end part of a half shaft to be dismounted is fixed at the other end of the connecting rod 1, the clamping sleeve 3 is hollow, one end, far away from the connecting rod 1, of the clamping sleeve is arranged in an opening mode, at least three threaded through holes 33 are uniformly formed in the circumferential direction of the side wall of the clamping sleeve 3, and a flat head bolt 31 used for fastening the half shaft is arranged on each threaded through hole 33; and a metal sliding block 4 for impacting the baffle disc 2 is sleeved on the connecting rod 1 between the baffle disc 2 and the clamping sleeve 3 in a sliding manner. When the tool is used, the clamping sleeve 3 is sleeved at the end part of the half shaft to be disassembled, then the half shaft to be disassembled is fixed by screwing the flat head bolt 31, then the sliding block 4 slides rapidly towards one end of the baffle disc 2, so that the sliding block 4 and the baffle disc 2 are impacted, and therefore the tool is used for generating tension on the half shaft, the half shaft is separated from the gearbox, and the disassembling work is completed.
It should be noted that this frock is more suitable for dismantling the tip does not have the screw half axle. If the end part of the half shaft is provided with threads, a plurality of circles of paper or anti-slip rubber layers can be wound at the positions where the threads are arranged, and then the half shaft and the half shaft are fixed through the clamping sleeve 3 and the flat head bolt 31, so that the threads on the half shaft are prevented from being damaged.
In the present embodiment, the flat head bolt 31 is an eyelet bolt, an inner hexagon bolt or an outer hexagon bolt. Preferably, the movable joint bolt is used, so that the bolt is conveniently adjusted, the tool is more simply and conveniently fixed with the half shaft, and the working efficiency is improved.
In the embodiment, the connecting rod 1 and the clamping sleeve 3 are in threaded connection; the connecting rod 1 is close to the one end of the clamping sleeve 3 is provided with an external thread 5, the clamping sleeve 3 is close to one side of the connecting rod 1 is fixed with a connecting block 32 which is used for being in threaded connection with the connecting rod 1, the connecting block 32 and the clamping sleeve 3 are integrally formed, a screw hole with an internal thread 6 is formed in the connecting block 32, and the screw hole is in threaded connection with one end of the connecting rod 1 provided with the external thread 5. The clamping sleeve 3 on the tool is convenient to replace and maintain, and the clamping sleeve 3 is convenient to adapt to the more suitable connecting rod 1.
In the present embodiment, the connecting rod 1 has multiple links, including a first link 11, a middle link 12 and a last link 13; one end of the first section of connecting rod 11 is fixedly connected with the baffle disc 2, and the other end is provided with the external thread 5; one end of the middle section connecting rod 12 is provided with an external thread 5, and the other end is provided with a connecting screw hole 7 with the internal thread 6; one end of the tail connecting rod 13 is connected with a clamping sleeve 3, and the other end of the tail connecting rod is provided with a connecting screw hole 7 with the internal thread 6; the external thread 5 is matched with the internal thread 6. The length of conveniently adjusting connecting rod 1 is set up like this, through the regulation of connecting rod 1 length, can adjust the slidable distance of slider 4 to indirectly adjust the size of slider 4 to 2 effort of fender dish, and then adjust the effort size of frock to the semi-axis.
In this embodiment, an anti-slip pad is fixed to the top end of the flat head bolt 31, so that the friction force between the flat head bolt 31 and the half shaft is increased, and the fixing is firmer.
In this embodiment, two circles of threaded through holes 33 are formed in the sidewall of the clamping sleeve 3 in a circumferentially staggered manner, and at least three threaded through holes 33 are formed in each circle. Set up like this, can make flat head bolt 31 more even with the atress of each contact point on the semi-axis, it is more firm to make this dismantlement frock and semi-axis end fixing, thereby can not cause the phenomenon of stress concentration harm semi-axis.
The above embodiments are only used for illustrating the present invention, and not for limiting the present invention, and those skilled in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention, so that all equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the claims.
