The half shaft sleeve is an important part of the automobile drive axle assembly, which forms an integral with the drive axle housing and is used to fix the axial relative position of the left and right drive wheels. The shape of the half shaft sleeve is mostly vertical and conical.

[0056] Embodiment 2, refer to Figures 1-3 、 Figures 5-9 The fitting mechanism 200 is provided for the second embodiment of the application.

[0057] The fitting mechanism 200 is used for clamping and fitting the sleeve pipe;

[0065] Specifically, the clamping component 203 can be used for clamping and holding the sleeve pipe with different shapes, and the rotation assembly 202 can drive the sleeve pipe to rotate circumferentially, thereby facilitating the welding work.

[0066] Further, the electric push rod 203a in the fitting mechanism 200 is started, the output end of the electric push rod 203a is extended, the connecting block 203b is driven to drive the fitting plate 203c to approach the surface of the sleeve pipe, if the sleeve pipe to be clamped is a vertical type, the two sides of the compression spring 207 are uniformly stressed, the fitting plate 203c keeps a horizontal state and is closely fitted with the outer wall of the sleeve pipe, the stable clamping force is provided by the pushing force of the electric push rod 203a, and the displacement of the sleeve pipe in the subsequent rotation is prevented;

[0067] If the sleeve pipe is a conical type, because the conical surface has an inclination angle, when the fitting plate 203c contacts the surface of the sleeve pipe, the reaction forces on the two sides are different, the right compression spring 207 with a greater elastic coefficient deforms more than the left compression spring 207, the fitting plate 203c is driven to rotate synchronously with the connecting block 203b, until the fitting plate 203c is completely fitted with the surface of the conical sleeve pipe, in this process, the scale ring 209 on one side of the connecting block 203b rotates with the connecting block 203b, the marker pin 208 (fixedly not moving) points to a specific scale on the scale ring 209, and the operator can intuitively judge the inclination angle of the fitting plate 203c through the corresponding identification of the marker pin 208 and the scale ring 209, and further determine the taper specification of the sleeve pipe, thereby providing a basis for subsequent adjustment of the welding speed and improving the welding precision.

[0068] Embodiment 3, refer to Figure 1 、 Figure 2 、 Figure 4、 Figure 9 For the third embodiment of the present application, a guiding mechanism 300 is provided.

[0069] The guiding mechanism 300 is used to assist the sleeve pipe in sleeving, rotating and taking out.

[0070] The guiding mechanism 300 comprises a fixing assembly 301 arranged on the left and right sides of the insertion ring 103, and a guiding component 302 arranged on the top of the fixing assembly 301.

[0071] The fixing assembly 301 comprises two groups of fixing plates 301a fixedly connected to the left and right sides of the insertion ring 103, and a through slot 301b is arranged in the middle of one of the fixing plates 301a.

[0072] The guiding component 302 comprises a guiding slot 302a arranged on the top of the fixing plate 301a, a guiding rod 302b fixedly connected to the inner side of the guiding slot 302a, an electric telescopic rod 302c and a compression spring 302d respectively sleeved on the outer side of the guiding rod 302b, a universal wheel 302e arranged on the top of the electric telescopic rod 302c, and a horizontal telescopic rod 302f arranged on the opposite side of the electric telescopic rod 302c.

[0073] Specifically, the guiding component 302 can provide an accurate insertion path for the sleeve pipe during the sleeving process, facilitate the insertion of the sleeve pipe, and facilitate the taking out of the sleeve pipe by the staff after the sleeve pipe is welded.

[0074] Further, first, the sleeve pipe is placed on the top of the universal wheels 302e on both sides of the insertion pipe, and the universal wheels 302e are moved to both sides on the surface of the guiding rod 302b under the action of the gravity of the sleeve pipe by using the compression spring 207, until the spacing between the universal wheels 302e is adapted to the diameter of the sleeve pipe, then the one end of the sleeve pipe is aligned with the center hole of the two groups of insertion rings 103, and the sleeve pipe is moved along the surface of the universal wheels 302e, and due to the steering characteristics of the universal wheels 302e, the universal wheels 302e are rotated and rotated with the surface of the sleeve pipe, so that the sleeve pipe is always inserted along the preset axis direction, and the both ends of the sleeve pipe are inserted into the inner side of the two groups of insertion rings 103, and the preliminary sleeving positioning is completed.

[0075] Finally, the sleeve pipe is taken out, the welding head 102 and the driving motor 202g are closed after welding, the output end of the electric push rod 203a is retracted, the abutting plate 203c is separated from the surface of the sleeve pipe, then the left electric telescopic rod 302c is gradually lowered from left to right, so that it presents an inclined shape, and the sleeve pipe is gradually slid to the left side under the action of its own gravity and the universal wheels 302e, thereby assisting the operator in taking out the sleeve pipe.

[0076] The rest of the structure is the same as that of Example 2.

[0077] Example 4, with reference to Figures 1-9 As the fourth embodiment of the present application, the difference between this embodiment and the third embodiment is that this embodiment provides a sleeving device for automobile part production.

[0078] In use of the device;

[0079] First, the operator places the sleeving pipe to be machined on the top of the universal wheels 302e on both sides of the insertion pipe, and the universal wheels 302e will move to both sides on the surface of the guide rod 302b under the action of the gravity of the sleeving pipe by using the compression spring 207, until the spacing between the universal wheels 302e adapts to the diameter of the sleeving pipe, then aligns one end of the sleeving pipe with the center hole of the two groups of insertion rings 103, and pushes the sleeving pipe to move along the surface of the universal wheels 302e, due to the steering characteristics of the universal wheels 302e, the universal wheels 302e can rotate and rotate with the surface of the sleeving pipe when the sleeving pipe is pushed, to ensure that the sleeving pipe is always inserted along the preset axis direction, so that the two ends of the sleeving pipe are inserted into the inside of the two groups of insertion rings 103 respectively, to complete the preliminary sleeving positioning;

[0080] Then start the electric push rod 203a in the fitting mechanism 200, the output end of the electric push rod 203a extends, pushes the connecting block 203b to drive the fitting plate 203c to approach the surface of the sleeving pipe, if the sleeving pipe to be clamped is vertical type, the two sides of the compression spring 207 are uniformly stressed, the fitting plate 203c keeps horizontal state and closely fits with the outer wall of the sleeving pipe, and the stable clamping force is provided by the pushing force of the electric push rod 203a to prevent the displacement of the sleeving pipe in the subsequent rotation;

[0081] If the sleeving pipe is conical, because there is an inclination angle on the conical surface, when the fitting plate 203c contacts the surface of the sleeving pipe, the reaction forces on the two sides are different, the right side compression spring 207 with larger elastic coefficient deforms more than the left side, drives the fitting plate 203c to rotate synchronously with the connecting block 203b, until the fitting plate 203c completely fits the surface of the conical sleeving pipe, in this process, the scale ring 209 on one side of the connecting block 203b rotates with the connecting block 203b, the pointer 208 (fixed) points to a specific scale on the scale ring 209, the operator can intuitively judge the inclination angle of the fitting plate 203c through the corresponding marks of the pointer 208 and the scale ring 209, and further determine the taper specification of the sleeving pipe, to provide basis for subsequent adjustment of welding speed and improve the precision of welding;

[0082] Subsequently, the sleeve pipe is rotationally welded, and the rotational speed of the driving motor 202g is set according to the sleeve pipe shape parameters (vertical type or conical type and its taper) displayed by the indicator 208 and the scale ring 209. If it is a vertical sleeve pipe, the welding efficiency can be improved by increasing the rotational speed, and if it is a conical sleeve pipe, a lower rotational speed can be used to ensure uniform welding seams.

[0083] The driving motor 202g is started, the output shaft of the driving motor 202g drives the driving gear 202f to rotate, the driving gear 202f is engaged with the toothed disc 202d on the outer side of the fixed ring 202c through the driving groove 202e on the surface of the plug-in ring 103, and drives the toothed disc 202d and the fixed ring 202c to rotate synchronously. At the same time, the rotating ring 202b on one side of the fixed ring 202c rotates along the rotating groove 202a on the inner side of the rotating groove 201, providing guidance and support for the rotation of the fixed ring 202c to avoid deviation of the fixed ring 202c. In addition, the toothed disc 202d rotates and engages with the second gear 205 in the annular groove 204, driving the second gear 205 and the transmission rod 206 to rotate synchronously. During the rotation of the fixed ring 202c, the sleeve pipe clamped on the inner side of the fixed ring 202c rotates synchronously with the fixed ring 202c. At this time, the welding head 102 at the top of the support plate 101 is started, and the welding head 102 is aligned with the plug-in welding part of the sleeve pipe. With the circumferential rotation of the sleeve pipe, the welding head 102 completes the annular welding of the plug-in part of the sleeve pipe.

[0084] Finally, the sleeve pipe is taken out. After welding, the welding head 102 and the driving motor 202g are turned off, the output end of the electric push rod 203a is retracted, and the abutting plate 203c is separated from the surface of the sleeve pipe. Then, the left electric telescopic rod 302c is gradually lowered from left to right, so that it presents an inclined shape. Under the action of its own gravity and the universal wheel 302e, the sleeve pipe will gradually slide to the left side, assisting the operator to take out the sleeve pipe.

[0085] In summary: through the setting of the abutting mechanism 200 and the guiding mechanism 300, different shapes of sleeve pipes can be abutted and clamped, and different rotational speeds can be changed according to different shapes of sleeve pipes to improve the welding precision.
