Description

Technical Field

[0001] This utility model belongs to the field of cab assembly technology, specifically relating to a positioning device for welding cab assemblies. Background Technology

[0002] The cab assembly is a crucial component of a vehicle body, serving as the core seating space for the driver and passengers. Its design integrates functionality, safety, and comfort. As the main superstructure of the vehicle, the cab assembly is typically assembled from large stamped sheet metal parts such as the floor, front bulkhead (instrument panel mounting area), side panels (including A / B / C pillars), roof, and rear bulkhead through welding, riveting, and adhesive bonding processes. This forms a rigid frame that supports the vehicle's control system, safety systems, and interior accessories. In commercial vehicles (such as trucks and construction vehicles), the cab assembly often employs a fully enclosed metal structure, flexibly connected to the chassis frame via a four-point suspension mechanism to isolate vibration and noise. Passenger vehicles, on the other hand, more often utilize a monocoque body design, integrating the cab with the body frame to achieve a balance between lightweight design and high rigidity.

[0003] Conventional positioning devices for cab assembly welding can only handle the positioning and clamping of cab assembly parts of a certain standard size. When welding cab assemblies that are beyond the standard size, there will be insufficient space, resulting in low flexibility and versatility. Therefore, we propose a positioning device for cab assembly welding. Utility Model Content

[0026] Example

[0027] Please see Figure 1-5 The technical solution provided in this embodiment is as follows:

[0028] A positioning device for welding a cab assembly includes: a fixed base 1, with multiple electric telescopic rods 2 fixedly connected to the top of the fixed base 1; characterized in that: a control panel 4 is fixedly connected to the surface of two electric telescopic rods 2; a splicing assembly 8 is fixedly connected to the top of the electric telescopic rods 2; a clamping assembly 9 is provided on the top of the splicing assembly 8; a screw storage box 3 is fixedly connected between the bottoms of the multiple electric telescopic rods 2; a connecting box 5 is fixedly connected to the top of the fixed base 1; a sliding groove 6 is provided on the inner wall of the connecting box 5; and a lighting lamp 7 is slidably connected to the inner wall of the sliding groove 6.

[0029] When assembling large or irregularly shaped cab assemblies, multiple devices can be installed as a whole through the structure of splicing component 8, thereby expanding the overall size of the device to accommodate cab assemblies of different sizes and irregular shapes, and providing a more solid welding positioning base.

[0030] In this embodiment, the fixed base 1 helps to support the entire device from the bottom, while the electric telescopic rod 2 can use its own structure to drive the splicing component 8 to move up and down. This structure realizes the up and down adjustment function, which is a device and principle well known to those skilled in the art and will not be described in detail here. The screw storage box 3 can help store the screws that need to be installed later. The control panel 4 can adjust the electric telescopic rod 2 to a suitable position after the device is in place, and then use the splicing component 8 to expand the working range. The connecting box 5 and the internal sliding groove 6 can drive the lighting lamp 7 to a suitable position to help illuminate from the bottom, making it easier for users to find the welding location by the light source when welding in the dark area, thus improving the functionality of the device. The splicing component 8 can use its own structure to correspond to parts of different sizes and models to help clamp the component 9 to install in the corresponding position, thereby further improving the flexibility of the device. In addition, when the volume of the cab assembly gradually increases during the welding process, multiple splicing components 8 can be spliced ​​together to expand the working space, thereby further improving the functionality of the device. The clamping component 9 can be fixed and spliced ​​on the surface of the splicing component 8, and can use its own structure to adjust the clamping point at any time to cope with parts of different heights and sizes.

[0031] The splicing assembly 8 includes a splicing plate 801, splicing clips 802, splicing mounting holes 803, splicing grooves 804, positioning mounting holes 805, and a first mounting screw 806.

The position of the splicing grooves 804 matches the splicing clips 802.

[0032] In this embodiment, the splicing component 8 is inserted into the splicing groove 804 inside the splicing plate 801 of another splicing component 8 through the splicing plate 801 and the splicing clip 802 on the surface for splicing installation, and is reinforced by the splicing mounting hole 803 and the first mounting screw 806, thereby improving the stability of the device during splicing.

[0033] Multiple positioning mounting holes 805 are evenly provided on the top of the splicing plate 801. A first mounting screw 806 is provided on the inner wall of one of the positioning mounting holes 805. The position of the first mounting screw 806 matches the splicing groove 804, and the size of the first mounting screw 806 matches the splicing mounting hole 803.

[0034] In this embodiment, the positioning mounting hole 805 can use its evenly distributed points to help flexibly install the corresponding parts of the clamping component 9, further improving the overall versatility of the device. The first mounting screw 806 can help reinforce the splicing component 8 after it is spliced, by passing through the splicing mounting hole 803 to the position of the corresponding positioning mounting hole 805.

[0035] The clamping assembly 9 includes a mounting plate 901, a mounting hole 902, a second mounting screw 903, a connecting plate 904, an adjusting groove 905, a limiting slide rail 906, a sliding adjusting block 907, a threaded clamping post 908, an auxiliary rotating plate 909, a stabilizing hole 910, and a stabilizing screw 911. The mounting plate 901 is located on the top of the splicing plate 801. The mounting hole 902 is located on the top of the mounting plate 901. The position of the mounting hole 902 matches the positioning mounting hole 805. The second mounting screw 903 is threaded to the inner wall of the mounting hole 902. The size of the second mounting screw 903 matches the mounting hole 902 and the positioning mounting hole 805.

[0036] In this embodiment, the clamping component 9 is placed on top of the splicing component 8 via the mounting plate 901, and the mounting fixing hole 902 corresponds to the position of the positioning mounting hole 805. The second mounting screw 903 is used for fixing and installation. This installation method uses the flexibility of multiple holes to install according to the parts to be clamped and installed, thereby further improving the overall versatility and safety of the device.

[0037] A connecting plate 904 is fixedly connected to the top of one end of a mounting plate 901. An adjusting groove 905 is formed on the inner wall of the connecting plate 904. A limiting slide rail 906 is fixedly connected to the top of the inner wall of the adjusting groove 905.

Holes adapted to the stabilizing screw 911 are formed on both sides of the sliding adjusting block 907.

[0038] In this embodiment, the connecting plate 904 can be linked with the adjusting groove 905 and the limiting slide rail 906 to provide a movable basis for the sliding adjustment position of the sliding adjusting block 907. This allows for vertical adjustment when clamping parts, and after adjustment to the corresponding position, the stabilizing screw 911 can be used to pass through the stabilizing hole 910 to stabilize the corresponding mounting holes on both sides of the sliding adjusting block 907 for fixation. After adjustment, the threaded clamping column 908 and the auxiliary rotating plate 909 are used to clamp the parts. The use of multiple position adjustments and vertical adjustment positions and ranges improves the overall applicability of the device and further enhances its functionality.

[0039] Working Principle: The user can support the entire device using the fixed base 1, which also provides a moving point for pushing the device when moving it. The electric telescopic rod 2 can use its internal structure to drive the overall height adjustment of the splicing component 8 to correspond to different parts of different sizes, thereby further improving the functionality of the device. The control panel 4 can help control the overall up and down adjustment of the device. The connecting box 5 and the internal sliding groove 6 can drive the lighting 7 from the bottom of the splicing component 8 to a suitable position to help the user provide light during positioning, thereby improving the functionality of the device. The splicing component 8 can use its own structure to combine with the clamping component 9 to position and clamp different sized cab assembly parts. Irregularly shaped parts can also be positioned and clamped, improving the overall versatility of the device. When encountering large cab assembly parts, the structure of the splicing component 8 itself can be used to splice multiple devices, thereby further improving the adaptability of the device. The clamping component 9 can use its own structure to adjust the center of gravity position at any time during the clamping of different components, thereby further improving the clamping effect of the device. The screw storage box 3 can help store the screws that need to be installed later, further improving the functionality of the device.
