A device for removing connecting screws of automobile sheet metal

Abstract

The invention discloses a vehicle metal plate connecting screw dismounting device, which is suitable for dismounting connecting screws on vehicle metal plates in a narrow space. The vehicle metal plate connecting screw dismounting device is characterized in that two driving rotary discs are positioned in the two ends of a main sleeve through bearings; the two driving rotary discs are connected through a transmission rod; the transmission rod is a polygon prism, and is made of an elastic material; the two ends of the transmission rod are connected between the driving rotary discs through insertion structures; the transmission rod is positioned in the main sleeve; multiple through holes are formed in each driving rotary disc by equal angles; a set of L-shaped connecting rods is positioned oneach driving rotary disc; six L-shaped connecting rods form one set, and are in parallel; one ends of the L-shaped connecting rods in each set correspondingly pass through holes in the correspondingdriving rotary disc; concave wheels sleeve the other ends of the L-shaped connecting rods, and are perpendicular to the driving rotary discs; limiting blocks are respectively positioned at the two ends of the L-shaped connecting rods; and nylon fiber layers are arranged on the outer surfaces of the L-shaped connecting rods.

Description

Technical field [0001] The invention provides an automobile sheet metal connecting screw disassembly device, which relates to a device for disassembling a connecting screw on an automobile sheet metal part, and belongs to the field of automobile manufacturing. In particular, it relates to a device suitable for use in a narrow space for disassembling connecting screws on automobile sheet metal parts. Background technique [0002] At present, sheet metal parts are mainly used for covering parts and load-bearing parts in automobiles. In the actual process, in order to be beautiful and reduce resistance, many connecting screws on automobiles are hidden, and most of them are located in grooves. Some screws The connection position is in a closed groove that cannot be disassembled, and the reserved space is narrow.

Problems solved by technology

[0002] At present, sheet metal parts are mainly used for covering parts and load-bearing parts in automobiles. In the actual process, in order to be beautiful and reduce resistance, many connecting screws on automobiles are hidden, and most of them are located in grooves. The connection position is in a closed groove that cannot be disassembled, and the reserved space is small. When it is necessary to remove the inner screw, the outer baffle needs to be disassembled first, and then proceed step by step. The screw in the groove cannot be disassembled and installed directly. Traditional Most of the current screw removal devices are straight-handled structures, which cannot reach into the working position for removal and installation of screws. The existing extension rods are used for removal, and the axis torque required for removal of screws is transformed through the universal joint. It becomes the torsion force in the vertical direction, and then disassembled by rotation, but due to the narrow space, the rotation in the vertical direction can exert force, and during the rotation process, the universal joint will appear twisted and protruding, which is easy to get stuck In the groove, it cannot be taken out, which will affect the subsequent disassembly;

[0003] Publication No. CN106625355A discloses an axis fixing device for a quick-turn wrench and a quick-turn wrench using the axis fixing device. Between the driving hole and the transmission hole, the driving hole extends along the first axis and is formed on the quick-turn wrench, the driving device of the quick-turn wrench is arranged in the driving hole and can drive the fixing member, and the transmission device of the quick-turn wrench is rotatably arranged on the body The shaft center fixing device of the quick turn wrench includes a shaft hole extending along a second axis and passing through one side of the shaft center fixing device. The transmission groove of the wrench, the second axis intersects the first axis of the drive hole and is perpendicular to each other, the transmission device of the quick-turn wrench can extend into the shaft hole and connect with the drive device, but only one side can be turned. When the screw position achieves multi-layer shading, the power transmission will be insufficient or not transmitted at all, which will affect the power input

[0004] Publication number CN107053056A discloses a wrench head combination type integrated wrench, including a handle, the front end of the handle is connected with a main wrench head, and a through hole is opened on the handle, and a rotating shaft is installed in the through hole, and the rotating shaft is connected with a second A pair of wrenches and a second pair of wrenches. The first pair of wrenches is located above the handle, and the second pair of wrenches is located in the middle of the handle. There is a groove for placing the second pair of wrenches in the handle, and the groove is located The side of the wrench away from the head of the main wrench, the upper surface of the handle is provided with a box for placing the wrench head of the first pair of wrenches, and the box is located on the side of the first pair of wrenches away from the head of the main wrench. Combination, in the actual use process, it does not have the ability to connect and drive in a narrow seam, so it will fall off during the transmission
