Positioning and clamping units 2 and electrical quick plug units 3 are arranged on both the left and right sides of the top of the bottom plate frame unit 1. The Y-direction transfer trolley 5 is slidably installed on the bottom plate frame unit 1 through the Y-direction guide rail unit 4, and the Y-direction transfer trolley 5 is located between the positioning and clamping units 2 on both sides.

The lower left and right symmetric column and cylinder assembly 22 is symmetrically installed on the bottom plate frame 11 on the left and right. The upper left and right symmetric column and cylinder assembly 21 is arranged above the bottom plate frame 11.

[0029] The positioning and clamping unit 2 is symmetric left and right and is used to clamp and position the side panel assembly frame fixture used for the vehicle type to be welded in production at the working position in the welding station.

[0030] The electrical quick plug unit 3 is symmetric left and right and functions to supply electricity and signals to the side panel assembly frame fixture, that is, to supply the required gas, electricity, and signals with the required flow rate to the side panel assembly frame fixture to be positioned and clamped. The electrical quick plug unit 3 is mainly composed of an electrical quick plug female end assembly and symmetric left and right electrical quick plug mounting seats.

[0031] The Y-direction guide rail unit 4 includes a guide rail mounting component 41 and a frame adjustment unit 42. The guide rail mounting component 41 is installed on the bottom plate frame 11 through the frame adjustment unit 42.

[0032] When the Y-direction guide rail unit 4 enters the working position in the welding station of the side panel assembly frame fixture, it guides and corrects the XZ direction of the vehicle body coordinates, and also supports and positions the XZ direction after entering the working position.

[0033] The Y-direction transfer trolley 5 includes an XZ-direction guiding and correcting roller group 51, a lubricating oil pump 52, an electrical quick plug female end 53, and a side panel frame 54. The bottom of the side panel frame 54 is slidably matched with the guide rail mounting component 41 through the XZ-direction guiding and correcting roller group 51. The lubricating oil pump 52 and the electrical quick plug female end 53 are arranged on the side panel frame 54. The electrical quick plug female end 53 is electrically plugged with the electrical quick plug unit 3.

[0034] The Y-direction transfer trolley 5 is used to fix the side panel assembly frame fixture and at the same time dock with the moving equipment track for transporting the side panel assembly frame fixture to ensure that the side panel assembly frame fixture can smoothly enter the working position.

[0035] The working principle of a precision steel structure system for side wall general assembly frame positioning in this embodiment is as follows:

[0036] This embodiment relates to a work station on an operation line, which is used for welding the body parts of a sedan. The body parts are clamped using the corresponding side wall general assembly frame fixture. This embodiment is an auxiliary side wall general assembly frame fixture that brings the body parts into the welding station for positioning and clamping.

[0037] When single model production is carried out, the specific working principle is as follows:

[0038] Step 1, the side wall general assembly frame fixture corresponding to this model enters the welding working position along with the Y-direction transfer trolley 5 through the Y-direction guide rail unit 4.

[0039] Step 2, when entering the working position, the Y-direction guide rail unit 4 plays a guiding and correcting role for the side wall general assembly frame fixture in the XZ directions of the body coordinate.

[0040] Step 3, the sensor of the bottom plate frame unit 1 identifies the positioning and clamping unit 2 that is guided into the working position by the Y-direction guide rail unit 4 and the Y-direction transfer trolley 5. After determining that the side wall general assembly frame fixture is in place, at this time, the positioning and clamping unit 2 positions the side wall general assembly frame fixture in the XYZ three directions. Then, the model identification sensor 16 of the bottom plate frame unit 1 verifies whether the positioned side wall general assembly frame fixture matches the model currently required for welding.

[0041] Step 4, after the frame is confirmed, the cylinder jaws on the positioning and clamping unit 2 extend to tighten and position the side wall general assembly frame fixture.

[0042] Step 5, after Steps 1 - 4, the robot in the work station welds this model.

[0043] When multi-model production is carried out, the specific working principle is as follows:

[0044] When the transfer equipment of the side wall general assembly frame fixture needs to transfer the side wall general assembly frame fixture outside the welding station for switching during the welding process, since the electrical and signal parts of the side wall general assembly frame fixture will be missing due to detachment, it is necessary to confirm in place by the Y-direction sensor corresponding to the side wall general assembly frame fixture on the 3 electrical quick-connect units in the above Step 3. Then, after the above Step 4 is completed, the cylinder on the electrical quick-connect unit 3 extends with the electrical quick-connect female end plate to engage with the electrical quick-connect male end plate on the side wall general assembly frame fixture. After confirming that the engagement is in place, gas, electricity, and signals are supplied to the side wall general assembly frame. Finally, the operation in the above Step 5 is carried out again.

[0045] It should be noted that in the above embodiments, as long as the technical solutions do not conflict, they can be arranged and combined. Those skilled in the art can exhaust all possibilities based on the mathematical knowledge of permutations and combinations. Therefore, the present utility model will no longer describe the technical solutions after permutation and combination one by one, but it should be understood that the technical solutions after permutation and combination have been disclosed by the present utility model.

[0046] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
