Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile manufacturing equipment, and particularly relates to a door gap and flushness adjustment tool. Background Art
[0002] With the rapid development of the domestic automobile market, the market's requirements for the quality of automobile bodies are gradually increasing. The body-in-white has gradually changed from the traditional steel material to the all-aluminum body. The inspection and adjustment tools between the traditional steel body and the door are mostly in the form of suction cups, curved nylon blocks with strong magnets and other devices.
[0003] These devices may have the following adverse phenomena when in use. The equipment with suction cups providing suction has high requirements for the cleanliness of the vehicle body surface. However, the large-area vehicle body stamping panels leave the stamping workshop and undergo multiple rounds of welding. The surface is often stained with oil and dust, and the suction cups need to be cleaned frequently, which increases the equipment maintenance cost. The suction cups are easy to wear. The equipment with curved nylon blocks inlaid with strong magnets is easy to absorb magnetic dust such as iron sand during use. The accumulated dust is difficult to clean and may scratch the surface of the vehicle body at the least, and affect the positioning accuracy at worst. In addition, because the magnetic force of the tooling itself is not easy to control, it is easy to cause sheet metal damage when taking and placing the tooling on the vehicle body, resulting in product rework or defective products, which increases the company's production costs, affects product consistency, is not conducive to improving the quality and accuracy of the vehicle body, and is also a waste of manpower. Utility Model Content
[0004] The purpose of the utility model is to provide a door gap and flushness adjustment tool to solve the problems existing in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a door gap face difference adjustment tool, comprising a door frame tightening handle, a slot block, a door adjustment handle, a door adjustment top cap, a locating pin connecting block, a locating pin holder and a locating pin; the door frame tightening handle passes through the slot block and is threadedly connected to it, the door adjustment handle also passes through the slot block and is threadedly connected to it, the door adjustment top cap is fixed to the end of the door adjustment handle, the locating pin holder is fixed to the slot block through the locating pin connecting block, the locating pin is fixed to the locating pin holder, and the side of the slot block has a slot.
[0006] Preferably, the slot block is a triangular structure.
[0007] Preferably, the positioning pin connecting block and the positioning pin support are connected via a first gasket bolt assembly.
[0008] Preferably, the positioning pin connecting block and the slot block are connected via a second gasket bolt assembly.
[0009] The beneficial effects of this utility model are: it is compatible with both traditional steel and aluminum bodies and can achieve control of door gap step differences. It allows door gap adjustment with a compact size, avoids the drawbacks of suction cup fixtures requiring maintenance and body cleaning, magnetic fixtures causing errors and easily damaging panels due to dust accumulation, and is easy to adjust and maintain.

[0015] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings and preferred embodiments.
[0016] like Figure 1 As shown, in order to solve the problem that the installation and adjustment of aluminum body doors cannot rely on traditional magnetic suction methods, and the magnetic suction method is prone to cause precision errors caused by scratches, pits and dust accumulation, the suction cup method relies on additional work such as cleaning the body and maintaining the suction cup to be used normally. In order to eliminate such adverse factors, the utility model provides a door gap and face difference adjustment tool, including a door frame tightening handle 1, a slot block 2, a door adjustment handle 3, a door adjustment top cap 4, a locating pin connecting block 5, a locating pin support 6, a locating pin 7, a first gasket bolt assembly 8, and a second gasket bolt assembly 9. Among them, the function of the door frame tightening handle is to tighten the edge of the door frame to stabilize the position of the tooling on the vehicle body, the function of the slot block is to limit the position of the tooling in the vehicle width direction, the function of the door adjustment handle is to drive the door adjustment top cap through the handle end face, and the door adjustment top cap and the door adjustment handle move together to realize the function of controlling the gap between the vehicle body and the door, the locating pin connecting block is responsible for connecting the locating pin holder and the slot block and also has the function of precision adjustment, the locating pin holder is responsible for installing the locating pin, and the locating pin is responsible for determining the precise position and turning point of the tooling on the vehicle body, and the first gasket bolt assembly and the second gasket bolt assembly can fine-tune the relative position of the fixture pin and the slot block.
[0017] Specifically, the door frame tightening handle passes through the slot block and is threadedly connected thereto. The door adjustment handle also passes through the slot block and is threadedly connected thereto. The door adjustment top cap is fixed to the end of the door adjustment handle. The locating pin holder is fixed to the slot block via the locating pin connecting block. The locating pin is fixed to the locating pin holder. The slot block has a slot on its side. The locating pin connecting block and the locating pin holder are connected by a first washer bolt assembly. The locating pin connecting block and the slot block are connected by a second washer bolt assembly.
[0018] When using, first open the car door, insert the locating pin of the tooling into the inner panel of the side panel, rotate the tooling until the slot is stuck in the edge of the door frame, then rotate the door frame to tighten the handle, fix the tooling, close the car door, and stick the car door on the door adjustment top cap, and finally slowly turn the door adjustment handle until the door is flush with the car body.
[0019] It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
