Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure cleaning machines, in particular to a high-pressure cleaning tool with air-tightness detection function. Background Art

[0002] When cleaning the valve body with a high-pressure cleaner, it needs to be able to withstand high-pressure flushing and ensure the accuracy of the position, so that the valve body can be cleaned quickly, conveniently and accurately, and the cleanliness inside and outside the valve body can be guaranteed.

[0003] In order to thoroughly clean the casting sand remaining in the inner hole of the workpiece and the iron filings generated during processing, ensure that the product does not move during high-pressure cleaning, and achieve precise positioning cleaning, the utility model designs a pneumatic clamping tooling with airtightness detection in conjunction with a four-axis turntable, which can clamp and clean three surfaces at a time and can clamp four valve bodies at a time to improve production efficiency. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a high-pressure cleaning tool with airtight detection, which has simple clamping, high cleaning efficiency and strong practicality.

[0005] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a high-pressure cleaning tool with airtightness detection, including a bridge plate, a cylinder connecting rod, a valve body locating pin, a sealing ring, a cylinder, a first valve body pressure plate, a spring and a second valve body pressure plate, five cylinder connecting rods are passed through the bridge plate, springs are sleeved on the cylinder connecting rods, valve body locating pins matching with the locating holes on the valve body are also provided on the bridge plate, a sealing ring matching with the bottom of the valve body is also provided on the bridge plate, the cylinder connecting rod is connected to the cylinder, the cylinder is arranged below the bridge plate, the second valve body pressure plate is provided on the top of the cylinder connecting rods at both ends, and the first valve body pressure plate is provided on the top of the middle cylinder connecting rod.

[0006] Preferably, the bridge plate is also provided with air blowing holes.

[0007] Preferably, a nozzle is inserted into the valve hole of the valve body.

[0008] Beneficial effects of the utility model:

[0009] 1. On a four-axis turntable, three surfaces and the inner hole of the valve body can be cleaned in one clamping, which optimizes the previous manual single-sided cleaning method. It not only solves the problem of complicated clamping, but also achieves a good cleaning effect.

[0010] 2. Adding air tightness detection can prevent the valve body from not being clamped tightly due to cylinder problems or improper placement of the valve body, which may cause damage to machine tools, tooling and personnel under the impact of the high-pressure cleaning machine.

[0011] 3. Clamping four valve bodies at one time greatly improves the cleaning efficiency and reduces the processing cost of the enterprise. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] Reference Figure 1-3 , this specific embodiment adopts the following technical scheme: a high-pressure cleaning tool with airtight detection, including a bridge plate 1, a cylinder connecting rod 2, a valve body locating pin 3, a sealing ring 4, a cylinder 5, a first valve body pressure plate 6, a spring 7 and a second valve body pressure plate 8. Five cylinder connecting rods 2 are passed through the bridge plate 1, and the cylinder connecting rod 2 is sleeved with a spring 7. The bridge plate 1 is also provided with a valve body locating pin 3 that matches the locating hole 31 on the valve body. The bridge plate 1 is also provided with a sealing ring 4 that matches the bottom of the valve body. The cylinder connecting rod 2 is connected to the cylinder 5, and the cylinder 5 is arranged below the bridge plate 1. The tops of the cylinder connecting rods 2 at both ends are provided with second valve body pressure plates 8, and the top of the middle cylinder connecting rod 2 is provided with a first valve body pressure plate 6.

[0019] It is worth noting that the bridge plate 1 is also provided with a blowing hole 41 .

[0020] In addition, a nozzle 10 is inserted into the valve hole 9 of the valve body.

[0021] The working principle of this specific implementation is as follows: the two positioning holes 31 on the valve body are respectively placed in the fixed positions on the positioning pin 3, and the four valve bodies are placed in sequence; the starter cylinder 5 switch causes the pressure plate 6 and the pressure plate 8 to compress the spring 7 and press the workpiece valve body. At the same time, the valve body presses the sealing ring, and another machine tool cylinder blows air through the small hole 41 to detect whether the pressure plate 6 and the pressure plate 8 are pressed tightly. After the airtightness test is normal, the machine tool starts to run to clean the valve body hole and surface. The high-pressure water outlet on the special nozzle 10 passes through the inside of the valve hole 9 to clean the iron filings and molding sand remaining in the valve body hole.

[0022] After cleaning, the cylinder 5 is released upward, and the spring 7 pushes the pressing plates 6 and 8 upward, thereby facilitating the removal of the valve body.

[0023] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
