Description

Technical Field

[0001] The utility model relates to the detection field, in particular to a swing type workpiece detection device. Background Art

[0002] With the continuous development of the automobile industry, major automobile manufacturers have shortened the production cycle for models with considerable sales to increase output. In the above production process, factors such as efficiency improvement, structural optimization, and cost reduction are very important, which has also led to an increasing degree of automation in the automobile production process.

[0003] If columnar parts (such as positioning columns, bolts, etc.) need to be installed on some workpieces, they need to be inspected in the subsequent process of installing the columnar parts. It is necessary not only to inspect whether the columnar parts are installed normally, but also to hydraulically inspect the relative position accuracy of the columnar parts (such as whether the height of the top protruding from the workpiece meets the requirements). In general, direct inspection using traditional inspection devices such as distance sensors can meet the inspection requirements.

[0004] However, sometimes the volume of such columnar parts is relatively small, and conventional detection methods are prone to deviations. If the detection results are inaccurate, it may affect the normal progress of subsequent processes.

[0005] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention

[0006] The utility model aims to solve the above-mentioned deficiencies in the prior art and proposes a swing-type workpiece detection device which has a simple structure, ingenious design and can accurately and stably realize workpiece detection.

[0007] The technical solution of the utility model is: a swing type workpiece detection device, characterized in that: the device comprises a mounting frame 1, the mounting frame 1 is connected to the cylinder body of the swing cylinder 2, and the end of the swing arm 3 of the swing cylinder 2 is provided with a detection mechanism 4,

[0008] The detection mechanism 4 includes a shell 5 directly connected to the swing arm 3, a connecting sleeve 6 is arranged in the shell 5, a trigger shaft 7 is movably connected in the connecting sleeve 6, a bottom end 8 is arranged at the bottom end of the trigger shaft 7, the contour of the bottom end 8 is larger than the inner hole of the connecting sleeve 6, the upper part of the trigger shaft 7 is threadedly connected with a trigger nut 9, and the trigger nut 9 is located above the connecting sleeve 6, and a spring 10 is also sleeved on the upper part of the trigger shaft 7, the bottom end of the spring 10 is in contact with the trigger nut 9, and the top end is in contact with the inner wall of the shell 5, and a distance sensor 11 is also arranged on the shell 5, and the trigger nut 9 can trigger the distance sensor 11.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] The swing-type workpiece detection device of this structural form has a simple structure, ingenious design, and reasonable layout. It designs a special detection mechanism to solve the problems existing in the traditional process of using sensors to directly detect protruding columnar parts on products. The trigger shaft in the detection mechanism can move upward after contacting the workpiece, allowing the trigger nut set on it to move to a position matching the distance sensor, thereby triggering the distance sensor. Through this brief detection method, the reliability of the detection can be guaranteed, and at the same time, the relative position relationship between the trigger nut and the distance sensor can be accurately adjusted and determined in advance, so the problem of detection deviation in the traditional direct detection process will not occur. In addition, the manufacturing process of this detection device is simple and the manufacturing cost is low. Therefore, it can be said that it has many advantages and is particularly suitable for promotion and application in this field. Its market prospects are very broad. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The specific implementation of the present utility model will be described below in conjunction with the accompanying drawings. Figures 1 to 4 As shown: A swing type workpiece detection device, which includes a mounting frame 1 as a basis, the mounting frame 1 is connected to the cylinder body of the swing cylinder 2, and the end of the swing arm 3 of the swing cylinder 2 is provided with a detection mechanism 4,

[0016] The detection mechanism 4 includes a shell 5 directly connected to the swing arm 3, a connecting sleeve 6 is arranged in the shell 5, a trigger shaft 7 is movably connected in the connecting sleeve 6, a bottom end 8 is arranged at the bottom end of the trigger shaft 7, the contour of the bottom end 8 is larger than the inner hole of the connecting sleeve 6, the upper part of the trigger shaft 7 is threadedly connected with a trigger nut 9, and the trigger nut 9 is located above the connecting sleeve 6, and a spring 10 is also sleeved on the upper part of the trigger shaft 7, the bottom end of the spring 10 is in contact with the trigger nut 9, and the top end is in contact with the inner wall of the shell 5, and a distance sensor 11 is also arranged on the shell 5, and the trigger nut 9 can trigger the distance sensor 11.

[0017] The working process of the swing-type workpiece detection device of the embodiment of the utility model is as follows: the detection device is fixed on the frame at the detection station by using the mounting frame 1, and the specific position of the mounting frame 1 is adjusted to ensure that the adding detection mechanism 4 can detect the workpiece at the detection station;

[0018] The workpiece is transported from the previous station to the inspection station by the manipulator or other transport mechanism. After the workpiece is in place, the control system sends a signal to the swing cylinder 2 in the inspection device, and the swing arm 3 of the swing cylinder 2 drives the inspection mechanism 4 to swing. After the swing arm 3 moves to the right position, the inspection mechanism 4 just contacts the top of the columnar part 12 on the workpiece.

[0019] Specifically, the bottom end 8 in the detection mechanism contacts the top end of the columnar part 12. Since the detection mechanism 4 as a whole moves downward relative to the columnar part 12, when the columnar part 12 is fixed, the trigger shaft 7 will move upward relative to the connecting sleeve 6 under the action of the columnar part 12. During the upward movement of the trigger shaft 7, the spring 10 is compressed, and the trigger nut 9 moves with the trigger shaft 7. When the detection mechanism stops moving, the trigger nut 9 can just trigger the distance sensor 11; that is, the distance sensor 11 can detect the trigger nut 9 when the swing cylinder 2 is in the detection state, indicating that the columnar part 12 is correctly installed on the current workpiece to be measured, and the height of the columnar part 12 protruding from the workpiece to be measured also meets the requirements; on the contrary, if the distance sensor 11 cannot be triggered, it means that the columnar part 12 is missing, or there is a deviation in the installation position of the columnar part 12;

[0020] After the inspection is completed, the swing cylinder 2 drives the swing arm 3 to swing in the opposite direction to make room, the inspected workpiece is removed, and a new workpiece to be inspected is placed on the inspection station, and the above operation is repeated for inspection.
