Problems solved by technology

[0007] The above-mentioned detection method adopted at this stage cannot realize the measurement of the thickness of the bottom plate during the production process, and cannot detect quality defects in time. Once a quality problem occurs during production, a batch of car bodies will need to be repaired or even scrapped, and , It is also necessary to arrange special personnel to carry out manual inspection, which will lead to low production efficiency and high production cost. In addition, the above-mentioned detection method cannot be fully inspected, and it is prone to missed inspections

Embodiment Construction

[0030] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0031] The present invention is applied in the flow drill screw tightening process (abbreviated as FDS in English).

[0032] The method for judging the thickness of the FDS bottom plate of the present invention includes a plurality of steps S1-S4, below in conjunction with reference to the attached image 3 Each step is described in detail.

[0033] Setting step S1, setting the standard value of the base plate thickness corresponding to each point on the vehicle body.

[0034] Acquisition step S2, obtaining the screw point length data of the FDS connecting screw and collecting the data information of the FDS device in the working process in real time. The position data at the maximum pressure of the stage, and the point number.

[0035] Processing step S3, according to the length data of the screw tip, the position data of the screw tip when it touches ...

Abstract

The invention discloses an FDS bottom plate thickness judgment method and device, electronic equipment and a storage medium. The judgment method comprises the following steps: a setting step: settinga bottom plate thickness standard value corresponding to each point location; an acquisition step: acquiring screw tip length data H and acquiring data information in the working process of the FDS equipment in real time, wherein the data information comprises position data L1 when the screw tip touches the bottom layer plate, position data L2 when the screw tip has the maximum pressure in the puncture stage, and a point position number; a processing step: according to the H, the L1, the L2 and the point location number, processing to obtain a real-time test calculation value and a standard value of the thickness of the bottom layer plate of the point location corresponding to the point location number; and a judgment step: comparing the real-time test calculation value with a standard value, if a judgment condition is met, judging that the thickness of the bottom plate of the point location is normal, and otherwise, judging that the thickness of the bottom plate of the point locationis reduced and giving an early warning. Whether the thickness of the bottom layer plate in the FDS process is reduced or not can be monitored in real time, and the quality problem in the production process can be found in time.

Description

technical field [0001] The invention relates to the technical field of vehicle body connection technology, in particular to a method, device, electronic equipment and storage medium for determining the thickness of an FDS bottom plate. Background technique [0002] The flow drilling screw tightening process is a cold forming process that conducts the high-speed rotation of the motor through the tightening shaft in the center of the equipment to the plastic deformation of the plates to be connected due to friction and heat, and then self-tapping and screwing. This process is a single-sided connection technology. , referred to as FDS in English. Some companies also refer to this process as hot-melt self-tapping process. [0003] Refer to attached figure 1 , which shows the key stages in the FDS process flow, the key stages include: 1. Pre-drilling; 2. Drilling; 3. Piercing; 4. Self-tapping thread; 5. Tightening; constant torque). [0004] Flow drilling screw tightening pro...
