[0001] The utility model relates to the technical field of welding stud lateral force detection auxiliary devices, in particular to a welding stud lateral force detection device. Background Art

[0002] The detection of the lateral force of welding studs is an important link in welding quality control. However, it should be noted that in the conventional detection of welding studs, the direct detection of "lateral force" is not common because the main concerns during the welding process are welding strength, position accuracy, perpendicularity, and welding defects.

[0003] Before installing other components, it is necessary to detect the lateral force of the welded studs first. There is no dedicated inspection tool for the existing detection of the lateral force of studs, and the existing detection methods have the problems of low detection efficiency and low detection accuracy. Therefore, it is particularly important to design a welding stud lateral force detection device to solve the above technical problems. Summary of the Utility Model

There is no dedicated inspection tool for the existing detection of the lateral force of studs, and the existing detection methods have the problems of low detection efficiency and low detection accuracy, and a welding stud lateral force detection device is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a welding stud lateral force detection device, including a mounting base, a cylinder is fixedly connected to the mounting base, a sliding rod is slidably connected in the cylinder, a limiting seat is also installed on the mounting base, the limiting seat is located on the right side of the cylinder, a sliding seat is slidably arranged in the limiting seat, the sliding seat is fixedly connected to the sliding rod, the right side of the sliding seat is detachably connected to a positioning seat through a limiting rod, a fixing plate is fixedly connected to the right end of the sliding seat, the fixing plate is arranged between the sliding seat and the positioning seat, and a stud to be measured is installed on the right side of the positioning seat.

[0007] Preferably, a pressure sensor is fixedly connected to the left end of the guide rod, and the pressure sensor is detachably connected to the fixing plate.

[0010] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0011] 1. In the present utility model, during use, through the setting of the detection device, the structure of the fixed plate, pressure sensor, guide rod, and measuring rod on the sliding seat driven by the electric cylinder to drive the sliding rod is used to detect the lateral force of the stud to be measured. After applying pressure and maintaining it for a period of time, the displacement sensor performs real-time detection on the induction head on the positioning seat. Once displacement occurs, it proves that the lateral force of the measured stud does not meet the requirements. Compared with the conventional situation where no special inspection tool is designed for detection, the technical solution adopted by the present utility model can complete the professional detection of the welded stud, improve the detection accuracy of the stud after welding, reduce the labor intensity of the staff, and the overall structure is compact, which is easy for the staff to install and maintain.

[0016] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0017] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may be practiced in other ways than those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0018] The present utility model provides a device for detecting the lateral force of a welding stud, which includes a mounting base 1. A cylinder 2 is fixedly connected to the mounting base 1. A slide bar 201 is slidably connected in the cylinder 2. A limit seat 202 is also mounted on the mounting base 1. The limit seat 202 is located on the right side of the cylinder 2. A slide seat 203 is slidably arranged in the limit seat 202. The slide seat 203 is fixedly connected to the slide bar 201. The right side of the slide seat 203 is detachably connected to a positioning seat 3 through a limit rod 306. A fixing plate 204 is fixedly connected to the right end of the slide seat 203. The fixing plate 204 is arranged between the slide seat 203 and the positioning seat 3. A stud 4 to be tested is mounted on the right side of the positioning seat 3. A measuring rod 301 is fixedly connected in the positioning seat 3. A guide rod 302 is slidably arranged at the left end of the measuring rod 301. The outer shapes of the guide rod 302 and the measuring rod 301 fit each other. The guide rod 302 is located on the right side of the fixing plate 204. A pressure sensor 303 is fixedly connected to the left end of the guide rod 302. The pressure sensor 303 is detachably connected to the fixing plate 204. The structural design of the pressure sensor 303 facilitates the collection of detection data.

[0019] When the welding stud lateral force detection device is actually used, first, the overall structure of the device for detecting the stud lateral force is installed on the robotic arm for work. The robotic arm starts to work, making the measuring rod 301 structure on the positioning seat 3 be at a fixed displacement from the stud 4 to be measured. Then, the control box automatically drives the electric cylinder 2 to start working. The electric cylinder 2 drives the sliding rod 201 to drive the sliding seat 203 to slide in the limit seat 202, driving the fixing plate 204 structure on the limit seat 202 to move from left to right along the limit rod 306 until the right end of the guide rod 301 abuts against the stud 4. At this time, the pressure sensor 303 at the left end of the guide rod 302 transmits the pressure data to the central control box in real time, and continuously increases the pressure through the electric cylinder 2. When the lateral force value meets the requirements, it is maintained for a period of time. At this time, the displacement sensor 304 monitors the relative position of the sensing head 305. Once the sensing head 305 has a displacement, it proves that the welding of the stud does not meet the requirements. If there is no displacement, the stud 4 to be measured meets the detection requirements. Through the setting of the detection device, the electric cylinder 2 is used to drive the sliding rod 201 to drive the fixing plate 204, the pressure sensor 303, the guide rod 302 and the measuring rod 301 structures on the sliding seat 203 to detect the lateral force of the stud 4 to be measured. After applying pressure and maintaining it for a period of time, the displacement sensor 304 detects the sensing head 305 on the positioning seat 3 in real time. Once there is a displacement, it proves that the lateral force of the measured stud does not meet the requirements. Compared with the conventional situation where no special inspection tool is designed for detection, the technical solution adopted by the present utility model can complete the professional detection of the welded stud, improve the detection accuracy of the stud after welding, reduce the labor intensity of the staff, and the overall structure is compact, which is easy for the staff to install and maintain.

[0020] As Figure 1-2 shown, a displacement sensor 304 is also installed on one side of the electric cylinder 2 where the mounting seat 1 is located. The sensing head 305 is fixedly connected to the positioning seat 3. The mounting seat 1 can be installed on the robotic arm for detection work.

[0021] The effect achieved by the entire embodiment 1 is that during use, the electric cylinder 2 continuously increases the pressure. When the lateral force value meets the requirements, it is maintained for a period of time. At this time, the displacement sensor 304 monitors the relative position of the sensing head 305. Once the sensing head 305 has a displacement, it proves that the welding of the stud does not meet the requirements. If there is no displacement, the stud 4 to be measured meets the detection requirements.

[0022] Working principle: First, install the overall structure of the device for detecting the lateral force of the stud on the robotic arm used for work. The robotic arm starts to work so that the measuring rod structure on the positioning seat is at a fixed position from the stud to be measured. Then, the control box automatically drives the electric cylinder to start working. The electric cylinder drives the sliding rod to drive the sliding seat to slide in the limit seat, driving the fixed plate structure on the limit seat to move from left to right along the limit rod until the right end of the guide rod abuts against the stud. At this time, the pressure sensor at the left end of the guide rod transmits the pressure data to the central control box in real time, and continuously increases the pressure through the air cylinder. When the lateral force value meets the requirements, maintain for a period of time. At this time, the displacement sensor monitors the relative position of the sensing head. Once the sensing head has a displacement, it proves that the welding of the stud does not meet the requirements. If there is no displacement, the stud to be measured meets the detection requirements.
