Description

Technical Field

[0001] The utility model relates to the field of automobile processing equipment, in particular to an anti-leakage detection mechanism for automobile welding projection welding screws. Background Art

[0002] Projection welding in automotive welding is a resistance welding method widely used in automobile manufacturing. It is done by pre-processing convex points on the workpiece (or using existing surfaces, chamfers, etc. on the workpiece that can concentrate current), then making these convex points contact with the surface of another workpiece and heating them with electricity, and finally forming welds at the contact points through pressure. Projection welding is a variation of spot welding, but compared with spot welding, projection welding has higher welding efficiency and better welding quality. In the automobile manufacturing process, projection welding technology is widely used to connect various parts.

[0003] The automobile welding projection welding screw leakage prevention detection mechanism is a detection device specially used to prevent welding leaks or missing screws when welding projection welding screws in the automobile manufacturing process. However, when some existing detection mechanisms are working, their commonly used sensors have a sensing distance of 3 to 5 mm. The size of some components is below or below this sensing distance threshold, resulting in the detection mechanism being unable to accurately sense their existence, which in turn affects the accuracy and reliability of the detection mechanism, and may lead to welding leaks or missing screws.

[0004] Therefore, it is necessary to provide a new automobile welding projection welding screw leakage detection mechanism to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an automobile welding projection welding screw leakage prevention detection mechanism which can sense some smaller components and improve the detection accuracy and reliability.

[0006] The utility model provides an anti-leakage detection mechanism for automobile welding projection welding screws, comprising a first bracket, one side of which is fixedly connected to a second bracket; a detection component, the detection component comprising a guide rod, a first connecting block, a screw spring, a sensor and an inductive proximity switch, one side of the second bracket is provided with a guide rod, the bottom of the guide rod is provided with a first connecting block, the bottom of the first connecting block is provided with a screw spring, the bottom of the screw spring is provided with a sensor, and the bottom of the sensor is provided with an inductive proximity switch.

[0007] As an anti-leakage detection mechanism for projection welding screws for automobile welding provided by the utility model, preferably, a second connecting block is provided at the bottom of the screw spring, and a fixing block is provided on one side of the second bracket.

[0008] As an automobile welding projection welding screw leakage detection mechanism provided by the utility model, preferably, a fourth bracket is provided at the bottom of the first bracket, a third bracket is provided on one side of the second bracket, and a support frame is provided at the bottom of the sensor.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The automobile welding projection welding screw leakage prevention detection mechanism is provided with a detection component. When the device is used for detection, the component first contacts the guide rod, causing the guide rod to bear a certain pressure, thereby allowing the guide rod to drive the screw spring to move. When the screw spring moves, it can drive the second connecting block to move, so that the movement of the connecting block can be sensed by the sensor, and the sensing signal can be transmitted, so that smaller components can be detected, thereby improving the accuracy and reliability of the detection of the device to a certain extent, and at the same time improving the working efficiency of the detection mechanism. It solves the problem that when some existing detection mechanisms are working, their commonly used sensors have a sensing distance of 3 to 5 mm, and the size of some components is below or below this sensing distance threshold, resulting in the detection mechanism being unable to accurately sense their existence, thereby affecting the accuracy and reliability of the detection mechanism, and possibly causing welding leaks or missing screws.

DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0017] Please refer to Figure 1、 Figure 2 、 Figure 3 and Figure 4 ,in Figure 1 A schematic structural diagram of a preferred embodiment of the automobile welding projection welding screw leakage detection mechanism provided by the utility model; Figure 2 for Figure 1 A schematic structural diagram of the detection component shown; Figure 3 for Figure 1 A schematic diagram of the structural connection between the first connecting block and the inductive proximity switch is shown; Figure 4 for Figure 1 The schematic diagram of the structural connection between the fixing block and the first bracket is shown. A leak detection mechanism for projection welding screws for automobile welding includes a first bracket 1, a second bracket 2 being fixedly connected to one side of the first bracket 1;

[0018] Detection component 3, detection component 3 includes a guide rod 301, a first connecting block 302, a screw spring 303, a sensor 304 and an inductive proximity switch 305. A guide rod 301 is provided on one side of the second bracket 2, the bottom of the guide rod 301 is provided with a first connecting block 302, the bottom of the first connecting block 302 is provided with a screw spring 303, the bottom of the screw spring 303 is provided with a sensor 304, and the bottom of the sensor 304 is provided with an inductive proximity switch 305.

[0019] In the specific implementation process, Figure 2 、 Figure 3 and Figure 4 As shown, a second connecting block 4 is provided at the bottom of the screw spring 303 , and a fixing block 5 is provided on one side of the second bracket 2 .

[0020] A fourth bracket 7 is provided at the bottom of the first bracket 1 , a third bracket 6 is provided on one side of the second bracket 2 , and a supporting frame 8 is provided at the bottom of the sensor 304 .

[0021] It should be noted that: under the action of the first bracket 1, the second bracket 2, the third bracket 6 and the fourth bracket 7, the device can be used normally. At the same time, by disassembling and assembling each bracket, it is convenient for the staff to disassemble and assemble the device and quickly repair it. At the same time, under the action of each bracket, the stability of the device during use can be improved. When the device is working normally, the guide rod 301 is in contact with the detected component, so that the guide rod 301 is subjected to a certain pressure. When the guide rod 301 moves, the pressure is transmitted to the inside of the screw spring 303, and then the screw spring 303 moves to a certain extent, so that the screw spring 303 can drive the second connecting block 4 to move. When the second connecting block 4 moves, the sensor 304 can sense its movement and then send a signal, so that smaller components can be detected, thereby improving the detection accuracy of the device to a certain extent, and at the same time improving the accuracy of the device during detection, thereby improving its work efficiency.

[0022] The working principle of the leakage prevention detection mechanism for projection welding screws in automobile welding provided by the utility model is as follows:

[0023] When the device is used to detect whether there are convex welded screws, under the action of the detected component, the guide rod 301 is subjected to a certain degree of pressure, and the guide rod 301 transmits the pressure to the inside of the screw spring 303 through the first connecting block 302, and the screw spring 303 is subjected to a certain degree of pressure. When the screw spring 303 is subjected to pressure, a certain degree of displacement occurs, so that the screw spring 303 can drive the second connecting block 4 to move, and when the second connecting block 4 moves, the sensor 304 can sense the movement of the second connecting block 4, and the sensor 304 can send a signal, so that the device can detect screws of different sizes, and thus the accuracy and precision of the detection of the device can be improved, thereby improving the reliability of the device.
