Description

Technical Field

[0001] The utility model relates to the technical field of water jets, in particular to a real-time height measuring device for water jets with a larger cutting angle. Background Art

[0002] Waterjet, which means using water as a knife, is a high-pressure water jet cutting technology. It can perform one-time cutting processing of any material with any curve (except water jet cutting, other cutting methods are limited by the type of material); the heat generated during cutting will be immediately taken away by the high-speed flowing water jet, and no harmful substances will be produced. The material has no thermal effect (cold cutting). After cutting, no secondary processing is required or easy. It is safe, environmentally friendly, fast, efficient, and can achieve cutting processing of any curve. It is convenient, flexible, and widely used. Water jet cutting is a mature cutting process method with good applicability. Since five-axis cutting is an inclined cutting, the height will directly affect the size and precision of the cut product. Different material unevenness and different thickness characteristics require the height of the cutter to be adjusted according to the changes in the material during cutting. Therefore, the height and changes of the material need to be detected at any time during cutting.

[0003] In view of this, our company applied for a utility model patent named "A real-time water jet height measurement device with better stability" on 2024-01-05, with application number 2024200264583. Its solution is mainly to use a miniature wire displacement sensor for height measurement, which will not cause wear and has a longer service life. In this application, two sets of slide rails and sliders are used to control the lifting and lowering of the lifting plate. Compared with one set of sliders and sliders, the shaking of the slide rails and sliders caused by the gap in their own structure can be further alleviated, so that the lifting plate has better stability when moving up and down, and the measurement accuracy is higher, saving detection time. When using a water jet to process a wash basin, it is necessary to cut the faucet hole, drain hole and overflow hole respectively. The faucet hole and drain hole are both flat, while the overflow hole is set on an inclined surface. When using a water jet to cut the overflow hole of the wash basin, the angle of the cutter head needs to be tilted. Since a height measuring sensor block is required for height measurement during water jet cutting, and the height measuring sensor block is generally a circular ring, when the tilt angle is too large, the water spray pipe placed in the cutter head assembly will interfere with the height measuring sensor block, resulting in some models of wash basins being unable to complete the entire processing process. The height measuring sensor block needs to be removed for processing, which is more troublesome. In addition, the lifting plate is a whole plate. In actual use, due to the effect of internal stress, the slide rail is easily stuck, resulting in the lifting plate not moving smoothly up and down. Utility Model Content

[0004] The utility model aims to solve the interference problem between the water jet pipe of the existing water jet cutting equipment and the height measuring induction block in the prior art, and proposes a real-time height measuring device for water jets with a larger cutting angle.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A real-time height measuring device for a water jet with a larger cutting angle comprises a cutter head assembly and a height measuring device installed on one side of the cutter head assembly, the height measuring device comprises a mounting plate and a protective cover connected to the mounting plate, a lifting cylinder and a lifting plate are respectively installed between the mounting plate and the protective cover, a miniature wire displacement sensor is installed on the inner wall of the mounting plate, a height measuring induction plate is installed at the bottom of the lifting plate, a height measuring induction block is installed at the bottom of the height measuring induction plate, and an opening for increasing the cutting angle is processed on the height measuring induction block.

[0007] Furthermore, a first slide rail and a second slider are respectively installed on the inner wall of the mounting plate, and a first slider and a second slide rail are respectively installed on the inner wall of the lifting plate, the first slide rail and the first slider are cooperatively connected to each other, and the second slide rail and the second slider are cooperatively connected to each other.

[0008] Furthermore, an L-shaped fixing plate is installed between the lifting plate and the first sliding block.

[0009] The beneficial effects of the utility model are as follows: an opening for increasing the cutting angle is processed on the height measuring sensor block, and when it is necessary to cut the overflow hole of the wash basin, it is only necessary to swing the water spray pipe in the cutter head assembly to the opening, thereby effectively avoiding interference between the water spray pipe and the height measuring sensor block, greatly increasing the swing angle of the cutter head, and meeting the processing requirements of products of different models; an L-shaped fixing plate is installed between the lifting plate and the first slider, and through this L-shaped fixing plate, the internal stress between the two sets of sliders and the slide rails can be better balanced, effectively preventing the lifting plate from being stuck, and improving the stability of the entire structure.
