TECHNICAL FIELD
[0001] The utility model relates to a tightness test fixture workpiece quick change tool for workpiece performance test field. BACKGROUND
[0002] Bubble method water flow test is a commonly used detection method, mainly used for evaluating the waterproof sealing performance of materials or structures. When the workpiece to be tested is immersed in water and pressure is applied, the overall waterproof sealing performance of the workpiece to be tested is detected and evaluated by observing the number, size and position of the bubbles.
[0003] The water flow test machine is composed of two parts, a test fixture for fixing the test workpiece, and a test frame for pressurizing the test workpiece. Due to the large volume and weight after mutual installation and combination, it is not suitable for single person to carry and install, and needs to be installed by a crane and two people in cooperation, and is set in the water flow test area. At the same time, the existing test machine is designed for the test workpiece, and cannot be compatible between different workpieces, causing waste of test machine manufacturing cost. UTILITY MODEL CONTENTS
[0004] The utility model aims at overcoming the defects of the prior art, and provides a water flow test fixture workpiece quick change tool.
[0005] One technical solution to achieve the above-mentioned purpose is: a water flow test fixture workpiece quick change tool, a base and a bridge plate;
[0006] The base is set in the test area of the water flow test, and a water flow leak test frame is set above the base. A cylinder facing directly downward is set on the platform of the water flow leak test frame. A bridge plate channel is opened along the length direction of the base on the central axis of the base. A base positioning pin hole is set on the bridge plate channel. A bridge plate conveying device is set in the middle of the bridge plate channel.
[0007] A water flow leak test fixture is installed on the bridge plate, which clamps the workpiece to be tested. Bridge plate positioning pin holes matching the base positioning pin holes are opened on the bridge plate.
[0008] During the water flow test, the bridge plate is set on the bridge plate channel, so that the workpiece to be tested is located directly below the cylinder. Then the bridge plate is positioned by the pin, and the cylinder is turned on to apply downward pressure to the workpiece to be tested.
[0009] Further, the bridge plate conveying device is connected to the front and rear stations through the bridge plate conveying device.
[0010] Further, the connection part of the bridge plate conveying device and the front and rear stations is provided with a waterproof sealing door.
[0011] Further, the cylinder is a pressure adjustable cylinder.
[0012] The advantage effect of the utility model lies in: the utility model discloses a water flow property test fixture workpiece quick-change tool, and the water flow property leak detection frame is fixed on the base in the water flow property test area, and the workpiece is fixed through the water flow property leak detection fixture on the bridge plate.

[0018] In order to better understand the technical scheme of the utility model, the following will be explained in detail through specific examples:
[0019] Please refer to Figs. 1 to 4 The utility model discloses a water flow property test fixture workpiece quick-change tool, adopts the structural form of base 1 and the bridge plate 4 of detachable combination.
[0020] The base 1 is arranged in the test area of water flow property test and is fixed and does not move.
[0021] The water flow property leak detection frame 2 is arranged above the base 1, and the material is stainless steel, the length is 400mm, the outer diameter is 400mm, and the width is 300mm. The platform of the water flow property leak detection frame is supported through four columns, and the installation hole is formed in the platform, and the air cylinder 3 is arranged in the installation hole and faces the directly below, so as to provide pressure for the test workpiece below. The air cylinder is an adjustable air cylinder, so as to meet the requirements of different test workpieces. A bridge plate channel is formed on the central axis of the base 1 along the length direction of the base, and the bridge plate channel passes below the water flow property leak detection frame. The base positioning pin hole is arranged on the bridge plate channel.
[0022] To make the transportation and installation of the bridge plate 4 more convenient, a bridge plate conveying device is arranged in the middle of the bridge plate channel. In one embodiment, the conveying device is a conveying roller. In another embodiment, the conveying device is a conveying belt. The bridge plate conveying device can make a single person carry and assemble the bridge plate.
