However, with the long-term use of the semi-automatic assembling device, the moving mechanism of the semi-automatic assembling device is abraded, so that the moving stroke of the semi-automatic assembling device deviates, the assembling position of the mandrel is out of standard, and the processing quality is affected. The production error problem that this kind of part damage leads to needs the maintenance personal to maintain the device by a wide margin, not only complex operation to cost of maintenance is too high.

In addition, if the semi-automatic assembling device is used for assembling air bladder shafts with different specifications, workers are required to adjust the moving mechanism of the semi-automatic assembling device and change the moving stroke of the moving mechanism.

In addition, because the air bladder is the rubber material, its in-process of preserving and transporting, the condition of buckling can appear in the difficult exemption, this degree of difficulty that has just increased the dabber assembly, even under the positioning action of anchor clamps, the dabber also is difficult to with the air bladder coaxial completely for the dabber is at the in-process of assembly, moves towards the direction of deviating the air bladder axis, arouses the dabber to push up the inner wall of air bladder, leads to the air bladder to warp or even damage.

The preliminary positioning assembly 31 includes a pushing member 311, and the pushing member 311 is slidably mounted on the guiding structure 22 for pushing the mandrel 80 into the assembling passage 902, so as to preliminarily assemble the mandrel 80. When the pushing member 311 moves along the guiding structure 22, the pushing member 311 pushes the mandrel 80 to enter the assembling channel 902 through the insertion opening 901, so as to be assembled on the shaft barrel 90.

Further, the preliminary positioning assembly 31 further includes a push-fit driving member 312, and the push-fit driving member 312 is controllably connected to the electric control mechanism 10, so that the electric control mechanism 10 can control the operation of the push-fit driving member 312. The pushing driving member 312 is mounted on the pushing member 311, and provides power for the movement of the pushing member 311, so as to control the pushing member 311 to move along the guiding structure 22.

The driving part 3122 is rotatably connected to the base body 21, and the driving part 3122 is connected to the driving part 3121 in a driving manner, so as to drive the pushing member 311 to move along a direction parallel to the extending direction of the guiding structure 22.

Preferably, the driving part 3121 is implemented as a motor, and the driving part 3122 is implemented as a screw.

Preferably, the pushing member 311 is mounted to the driving member 3121, the entrainment member 3122 is screw-coupled to the base main body 21, and the entrainment portion 3122 moves in a direction parallel to the extending direction of the guide structure 21 when the driving member 3121 rotates.

Specifically, the precision positioning member 32 is mounted to the pushing member 311. It should be noted that, since the pushing element 311 is interfered by the shaft sleeve 90 during the moving process, the core shaft 80 cannot be pushed to the predetermined position in the shaft sleeve 90 accurately, and therefore, the precise positioning element 32 is provided to further assemble and position the core shaft 80 and the shaft sleeve 90 during the secondary assembly process. If the preliminary positioning assembly 31 is not provided, but only the precise positioning member 32 is relied on, accumulated errors are generated in the pushing process of the precise positioning member 32, and particularly, when the mandrel 80 is installed into the insertion port 901 of the bushing 90, because the errors are large in the process of initially installing the mandrel 80 into the bushing 90, the pushing member 311 of the preliminary positioning assembly 31 can firstly push the mandrel 80 into the bushing 90 until the pushing member 311 reaches the maximum stroke, and the electrical control mechanism 10 can perform positioning of the relative position between the mandrel 80 and the bushing 90.

When the driving unit 322 operates, the auxiliary pushing unit 321 pushes the mandrel 80 to move further based on the basis of the preliminary assembly of the pushing member 311, so that the mandrel 80 is inserted into the predetermined position of the assembly channel 902, thereby assembling the mandrel 80 to the shaft barrel 90.

Specifically, the driving part 3121 is controlled by the electrical control mechanism 10 to operate, the pushing and installing driving part 312 drives the driving part 3122 to rotate, since the driving part 3122 is connected with the base main body 21 by threads, and the pushing element 311 is installed on the driving part 3122, so that the driving part 3122 moves along a direction parallel to an extending direction of the guiding structure 22, and the driving part 3122 drives the pushing element 311 to move along the guiding structure 22 in a direction close to the shaft cylinder 90 carried on the base main body 21, at this time, the spindle 80 arranged on the pushing element 311 is coaxial with the shaft cylinder 90 and abuts against the auxiliary pushing unit 321 carried on the pushing element 311, so that the pushing element 311 pushes the spindle 80 through the insertion port 901 while moving to enter the assembling channel 902, and realizing preliminary assembly. Subsequently, the driving unit 322 is controlled by the electrical control mechanism 10 to operate, the driving unit 322 drives the auxiliary pushing unit 321 to move along a direction parallel to the extending direction of the guiding structure 22, the auxiliary pushing unit 321 pushes the mandrel 80 to move further in the assembling channel 902, so that the mandrel 80 is assembled at the predetermined position of the shaft cylinder 90, and the assembling position of the mandrel 80 is further adjusted, so as to compensate assembling deviation of the disposable assembling device caused by mechanical wear, thereby realizing accurate assembling. Meanwhile, the movement stroke of the pushing unit 322 can be controlled by the driving unit 322 to control the spindle 80 to be assembled at different positions of the shaft cylinder 90, so as to meet the assembly requirements of spindle assemblies with different specifications.

It is worth mentioning that the cross-sectional dimension of the abutting portion 321A is larger than the cross-sectional dimension of the channel 801A and not larger than the cross-sectional dimension of the assembling channel 902A, so that the abutting portion 321A can enter the assembling channel 902A through the insertion interface 901A, thereby pushing the mandrel 80A to completely enter the shaft barrel 90A.

It is worth mentioning that two adjacent flaring assemblies 33 are equidistantly distributed on the shaft barrel 90. Preferably, there are two flaring assemblies 33, and the two flaring assemblies 33 are symmetrically arranged with reference to the central axis of the shaft barrel 90, so that when the two flaring assemblies 33 are respectively away from each other along the radial direction of the insertion port 901, both the two flaring assemblies 33 apply a pulling force to the shaft barrel 90, so that the insertion port 901 is deformed, thereby expanding the insertion port 901.
