Embodiment Construction
[0055] The lifting type automatic leak detector with follow-up guiding function of the present invention will be further described below in conjunction with the accompanying drawings.
[0056] exist figure 1 , 4 , 5, 6 to 15, shows the general embodiment 1 of the lift-type automatic leak detector with the function of following the guide.
[0057] exist figure 1 , 6 Showed the overall structure of automatic leak detector in and 9, and this embodiment is aimed at Figure 4 and Figure 5 The design scheme of the tested workpiece shown in , the arrow in the figure is the moving direction of the tested workpiece. Since the tested workpiece is installed with hexagonal bolts to fix the half-shaft tiles, the direct guide surface formed by the outer contour of the cylinder of the two rows of hexagonal bolts as an accessory is used as a guiding element that engages with the guiding elements of the guiding and positioning assembly to complete the leak detection work. .

The invention relates to a machine which detects the leakage of workpieces to be detected through a differential pressure method in a dried mode, wherein the machine is connected to a leakage detection automatic production line in series. The machine is particularly suitable for enabling the workpieces, with no proper law for appearance, to be detected to be in a posture which is suitable for stable transportation or transfer so that the leakage detection work can be conducted, and the proper posture needs to be assisted through accurate positioning in the sealing link and accurate guiding in the transportation link special for the correct lifting type automatic leakage detection machine. The automatic leakage detection machine comprises a machine frame assembly, a driving roller assembly, an upper clamp assembly, lifting mechanism assemblies, a lower clamp assembly, a pressure fluid driving system, a guiding and positioning assembly, a front blocking assembly and an electrical control system, and the machine frame assembly, the driving roller assembly, the upper clamp assembly, the lifting mechanism assemblies, the lower clamp assembly, the pressure fluid driving system, the guiding and positioning assembly, the front blocking assembly and the electrical control system are composited to form the mechanical and electrical integrated lifting type automatic leakage detection machine. The lifting type automatic leakage detection machine with the follow-up downward-guiding function has various guiding structure forms, can adapt to the workpieces to be detected in various forms, can meet the requirement for automatic leakage detection, is high in reliability, improves the production efficiency and is low in cost.
Description
technical field [0001] The invention relates to a machine for dry-type leakage detection of workpieces to be measured by differential pressure method. The machine is connected in series in the automatic production line of leak detection; Stable conveying or transferring attitude for leak detection work, this appropriate posture needs to be assisted by reasonable positioning of the special sealing link and guidance of the conveying link in the lifting automatic leak testing machine. Background technique [0002] In the processing and production of the metal casing of the engine of the automobile and other transportation equipment, it is necessary to perform leak detection on the casing. If there is leakage in the metal cylinder with defects such as trachoma, follow-up measures need to be taken to deal with it. The leak detection work needs to be carried out in The leak testing machine in the automatic production line needs to use the closure of the upper and lower fixtures to...
