Description

Technical Field

[0001] The invention belongs to the technical field of automobile production, and in particular relates to an auxiliary welding table for manufacturing automobile parts. Background Art

[0002] In the automobile production process, welding technology is required for parts such as chassis and frame. In the prior art, a basic welding table is first built, and then the components to be welded are pre-positioned on the welding table before welding. However, when changing the model of the welded frame or chassis, designers often only adjust the local design of the chassis as needed for the convenience of design, but the welding table used for welding often needs to be replaced as a whole, resulting in a long processing time for the new welding table to be fixed during the replacement process, and increasing the production cost and the time used in the process of replacing the welding table. Summary of the invention

[0003] In view of this, the present invention aims to provide an auxiliary welding table for automobile parts manufacturing, so as to improve the efficiency of welding table replacement when producing similar automobile parts and save costs.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0029] The automobile parts manufacturing auxiliary welding platform of the present invention comprises:

[0030] Base 1, on which there are a plurality of socket holes 11. A plurality of detachable connection support units 2 and limit units 3 can be arranged on the base 1 according to the outer shape structure of the parts to be welded. In some working scenarios, only the support unit 2 or the limit unit 3 can also be arranged. The support unit 2 and the limit unit 3 are respectively connected to the socket holes 11 of the base 1 through socket joints 4. In this embodiment, the support unit 2 is a support block or a support plate, and each support block or support plate is at a different height according to the structure of the parts to be welded, and supports the main part of the parts to be welded. The main part of the parts to be welded can be a metal plate in the middle of an automobile chassis, a battery shell, etc. The limit unit 3 is used to be arranged on the periphery of the support unit 2, and the branch parts to be welded on the main part of the parts can be fixed on the limit unit 3. The branch parts are such as reinforcing beams. The limit unit 3 includes a cross beam 31. A support platform 33 extends out from one side of the lower surface of the cross beam 31. A compression spring 32 is arranged on the side of the cross beam 31 facing the support platform 33. At least two vertical pipes are fixedly arranged at the bottom of the cross beam 31, and the vertical pipes can be connected to the socket joint 4. The compression spring 32 includes a U-shaped hanging part 321 and an elastic part 322. The elastic part 322 is in a "D" shape. A hook body 331 extends upward from the outer end of the support platform 33. Parts to be welded such as reinforcing beams are placed between the elastic part 322 and the hook body 331, and are temporarily fixed to the hook body 331 through the compression spring 32. After welding is completed, the welded parts are lifted by a manipulator, so that the parts are separated from the limit unit 3, and the welding table waits for the next part to be welded. In other embodiments, the positions of the support unit 2 and the limit unit 3, as well as the shapes and structures of each unit, can be set as required, rather than being limited to the technical solutions in this embodiment.

[0031] Each of the plug connectors 4 includes a connecting portion 43 and a plug tube. The connecting portion 43 is fixedly arranged at one end of the plug tube. The plug tube can be inserted into the plug hole 11. A pin 41 is arranged at one side of the plug tube. A boss 12 is arranged on the hole wall of the plug hole 11. When the plug tube is inserted into the plug hole 11, the pin 41 can be placed under the boss 12. Specifically, the cross section of the pin 41 is a right-angled trapezoid, and its hypotenuse faces the end away from the connecting portion 43. A spring 45 is arranged in the plug tube, and one end of the spring 45 abuts on the pin 41. A through hole is opened on one side wall of the plug tube. The pin 41 can pass through the through hole and be placed outside the plug tube. The edge of the part of the pin 41 placed in the plug tube is provided with a flange (not shown in the figure), which can abut against the inner wall of the plug tube to prevent the pin 41 from slipping out of the plug tube. The cross section of the boss 12 is a right-angled trapezoid, and its hypotenuse faces the end away from the connection portion 43, so that when the plug-in tube is inserted into the plug-in hole 11, the hypotenuse of the pin 41 can abut against the boss 12 and move into the plug-in tube under the guiding force of the hypotenuse. When the support unit 2 or the limit unit 3 needs to be replaced, the plug-in tube is first pulled out, and the pin 41 abuts against the hypotenuse of the boss 12 and moves into the plug-in tube under the guiding force of the hypotenuse, so that the plug-in tube can be disengaged from the plug-in hole 11. In order to prevent the plug-in tube from being separated from the plug-in hole 11 when the welded parts are separated from the limit unit 3, the elastic coefficient of the compression spring 32 is smaller than the elastic coefficient of the spring 45, so that when the plug-in tube moves upward, the resistance generated by the pin 41 contacting the edge of the boss 12 is greater than the resistance between the compression spring 32 and the workpiece.

[0032] The boss 12 can be fixed to the hole wall of the plug hole 11 by bolts. Specifically, a cavity is provided inside the base 1, and the plug hole 11 is placed in the cavity in a tubular shape. The bolts can pass through the cavity and be fixed to the boss 12 through the side wall of the plug hole 11. A cut surface 46 is provided on one side of the plug tube, and the boss 12 is opposite to the cut surface 46, and the outer surface of the boss 12 can abut against the cut surface 46 to prevent the plug tube from rotating when inserted into the plug hole 11.

[0033] The connecting portion 43 includes a threaded rod, and a screw hole is formed on the supporting unit 2 and / or the limiting unit 3. The threaded rod can be screwed with the screw hole, and a nut 44 is also screwed on the connecting portion 43, and the nut 44 can be pressed against the supporting unit 2 and the limiting unit 3. The height of the supporting unit 2 and the limiting unit 3 can be adjusted by the threaded rod, and then the height can be locked by the nut 44.

[0034] A limiting platform 47 is provided between the connecting portion 43 and the plug-in portion 42 . When the plug-in tube is inserted into the plug-in hole 11 , the limiting platform 47 abuts against the upper surface of the base 1 .

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
