Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile assembly, and in particular relates to a positioning tool for assembling a vehicle body and a vehicle frame. Background Art
[0002] Non-load-bearing vehicles have a clear body and frame structure. The body and frame assembly lines are planned separately in the assembly workshop for subassembly, and then assembled at the assembly station after completion. However, since the transportation system is divided into an aerial EMS hoisting part and a ground panel chain part, the amount of shaking during the assembly process is large, resulting in a long adjustment time and affecting production efficiency.
[0003] In the prior art, the body is carried by the EMS sling with a positioning accuracy of ±3cm, the frame is assembled on the ground drag chain conveyor line, and after the tires are installed, it falls on the floor chain with an accuracy of about ±5cm. The body and frame must be assembled together and the gap between the rear bumper and the body must be uniform, which requires manual adjustment, and the working time is about 5-6 minutes. The rear bumper is assembled on the frame, and the gap between it and the body must be uniform. During the adjustment process, it is necessary to manually use a gap gauge to adjust and measure. It can be seen that the operation of the prior art is relatively complicated and time-consuming, which seriously affects the assembly efficiency. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a positioning tool for assembling a vehicle body and a vehicle frame, which not only improves the assembly accuracy and makes the gaps between accessories relatively uniform, but also optimizes the assembly process and reduces the subsequent adjustment time, thereby effectively improving the assembly work efficiency.
[0005] The positioning tool for assembling a vehicle body and a vehicle frame comprises: a handle, a support platform, a positioning column, and a guide column. The handle is installed at one end of the support platform, and the positioning column is installed at the other end. The guide column is installed at the end of the positioning column away from the support platform.
[0006] Preferably, a circular ring is provided at one end of the handle, and an outer side wall of the circular ring is connected to the support platform.
[0007] Preferably, an extension rod is also installed on the outer side wall of the ring, and the extension rod is in the same straight line as the positioning column and the guide column.
[0008] Preferably, a nut is installed at one end of the extension rod away from the ring.
[0009] Preferably, the diameter of the guide column is smaller than the diameter of the positioning column.
[0010] Preferably, the support platform, the positioning column and the guide column are fixedly connected.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. Improved assembly accuracy, making the gaps between accessories relatively uniform.
[0013] 2. The assembly process is optimized and the subsequent adjustment time is reduced, thereby effectively improving the assembly work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described below in conjunction with the accompanying drawings:
[0019] The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0020] like Figure 1 and Figure 2 As shown, a positioning tool for assembling a vehicle body and a frame comprises: a handle 100, a support platform 200, a positioning column 300, and a guide column 400. The handle 100 is installed at one end of the support platform 200, and the positioning column 300 is installed at the other end. The guide column 400 is installed at the end of the positioning column 300 away from the support platform 200. In this way, the staff can easily place the device between the vehicle body and the frame by using the guide column 400, and position the vehicle body and the frame by using the positioning column 300, so that the vehicle body and the frame are in a relative position. Its supporting surface is placed in the suspension mounting plate of the vehicle body to cooperate with the limit, and the installation position of the device is adjusted by the handle 100. Through the mutual cooperation between the various components, the vehicle body and the frame can be positioned quickly and accurately, which not only improves the assembly accuracy, but also improves the efficiency of the assembly work.
[0021] like Figure 1 and Figure 2As shown, a ring 101 is provided at one end of the handle 100, and the outer side wall of the ring 101 is connected to the support platform 200. In this way, the staff can make manual adjustments through the provided ring 101. Alternatively, the staff can insert a tool into the ring 101 and use the ring 101 as a linkage force point to adjust the vehicle body or frame, which effectively improves the efficiency and accuracy of the adjustment.
[0022] like Figure 1 and Figure 2 As shown, an extension rod 102 is also installed on the outer side wall of the ring 101, and the extension rod 102 is in the same straight line as the positioning column 300 and the guide column 400. In this way, the extension rod 102 further improves the operability of the staff, making it easier for the staff to adjust the device, thereby improving the assembly accuracy of the vehicle body and the frame.
[0023] like Figure 1 and Figure 2 As shown, a nut 103 is installed at one end of the extension rod 102 away from the ring 101. In this way, the staff can adjust the assembly of the vehicle body and the frame with the help of tools and the positioning device, thereby improving the assembly accuracy of the vehicle body and the frame.
[0024] like Figure 1 and Figure 2 As shown, the diameter of the guide column 400 is smaller than the diameter of the positioning column 300. In this way, the diameter of the positioning column 300 is larger than the diameter of the guide column 400, which plays a limiting role, preventing the positioning column 300 from being inserted too deep and affecting the positioning effect. In addition, the larger diameter of the positioning column 300 can be adapted to the vehicle body and the frame, ensuring that the vehicle body and the frame are in relative positions, thereby improving the assembly accuracy of the vehicle body and the frame.
[0025] like Figure 1 and Figure 2 As shown, the support platform 200, the positioning column 300, and the guide column 400 are fixedly connected. In this way, the connection strength between the components is effectively improved through the integrated fixed connection structure, so that the positioning device is not easy to break during the adjustment process, ensuring that the adjustment work can be carried out smoothly.
[0026] like Figure 3 As shown, the support platform 200, the positioning column 300, and the guide column 400 are detachably connected, so that the staff can choose to connect the guide column 400 and / or the positioning column 300 of different specifications according to the actual work requirements, thereby improving the adaptability of the positioning device.
[0027] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
