[0042] Please refer to the accompanying drawings Figure 1 , Figure 1 The structure diagram of the lifting water spraying mechanism provided by the embodiment of the present application is shown. The embodiment provides a lifting water spraying mechanism, which includes a main water pipe 1000, a distribution pipe 2000, a spray head 3000, a movable block 4000 and a movable guide rail 5000. The distribution pipe 2000 is provided with a plurality of assembly ports 2001, and the spray head 3000 is arranged on the assembly ports 2001. In order to realize flexible adjustment of the direction of the spray head 3000, an adjusting connecting piece 6000 is arranged between the spray head 3000 and the assembly port 2001. Through the adjusting connecting piece 6000, the operator can change the direction of the spray head 3000 according to the actual demand, so as to make the water spraying coverage more reasonable and meet the water spraying demand in different scenes.

[0043] The inside of the distribution pipe 2000 and the inside of the main water pipe 1000 are in communication with each other, which ensures that the water flow can smoothly flow from the main water pipe 1000 into the distribution pipe 2000, and then be sprayed out through the spray head 3000. The outside of the main water pipe 1000 is connected with the movable block 4000, and the movable block 4000 is movably assembled on the movable guide rail 5000. Such design makes the whole lifting water spraying mechanism move up and down along the movable guide rail 5000. When it is necessary to adjust the water spraying height, a driving device is not mentioned in the present description, but in actual application, the movable block 4000 can be driven to move on the movable guide rail 5000, thereby driving the main water pipe 1000, the distribution pipe 2000 and the spray head 3000 to move up and down together, realizing water spraying operation at different heights.

[0044] In some embodiments of the present application, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration various embodiments in which the application can be practiced. Figure 2 and the accompanying drawings that form a part hereof, and in which is shown by way of illustration various embodiments in which the application can be practiced. Figure 3 , Figure 2 The structural schematic diagram of the adjusting connector provided by the embodiments of the present application. Figure 3 The sectional view of the adjusting connector provided by the embodiments of the present application. The adjusting connector 6000 shown is composed of a first connecting pipe 6001, a second connecting pipe 6002 and a third connecting pipe 6003. One end of the first connecting pipe 6001 is rotationally connected to the assembly port 2001 of the distribution pipe 2000, and in the unfixed state, the first connecting pipe 6001 can rotate relative to the assembly port 2001 to achieve a certain range of swing. The side wall of the second connecting pipe 6002 is rotationally connected to the other end of the first connecting pipe 6001, which makes the second connecting pipe 6002 not only move with the swing of the first connecting pipe 6001, but also rotate at the connection part with the first connecting pipe 6001, further increasing the adjustable angle range. The third connecting pipe 6003 is rotationally connected to the end of the second connecting pipe 6002, and the spray head 3000 is assembled on the third connecting pipe 6003, so that the spray head 3000 can rotate with the third connecting pipe 6003. Moreover, the internal spaces of the first connecting pipe 6001, the second connecting pipe 6002, the third connecting pipe 6003 and the spray head 3000 are sequentially communicated, ensuring that the water flow can smoothly flow from the distribution pipe 2000 to the spray head 3000 through the adjusting connector 6000. The beneficial effects brought by this arrangement are remarkable. The design of multiple rotation connection points greatly improves the flexibility of the orientation of the spray head 3000, and the operator can accurately adjust the orientation of the spray head 3000 according to the actual scene, such as different shapes of the site, different distribution of the to-be-sprayed water area, etc., so that the water spraying coverage is more reasonable, meeting the water spraying needs in various complex scenes and improving the efficiency and effect of water spraying operation. Secondly, the design of sequentially communicating internal spaces ensures the stability of water flow transmission, which will not affect the normal spraying of water flow due to the structure of the connector, and ensures the overall performance of the lifting water spraying mechanism.

[0045] In some embodiments of the present application, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration various embodiments in which the application can be practiced. Figure 4 and the accompanying drawings that form a part hereof, and in which is shown by way of illustration various embodiments in which the application can be practiced. Figure 5 , Figure 4 The assembly schematic diagram at the communicating valve provided by the embodiments of the present application. Figure 5The cross-sectional view of the communication valve provided by the embodiment of the present application. The communication valve 7000 shown should be installed at the connection of the main water pipe 1000 and the distribution pipe 2000, ensuring that the water flow from the main water pipe 1000 into the distribution pipe 2000 can be effectively controlled. This position should be convenient for operation and maintenance, usually selected in an easily accessible place, avoiding installation in narrow or difficult to reach space. Flange connection, threaded connection or welding can be used to firmly install the communication valve 7000 between the main water pipe 1000 and the distribution pipe 2000, ensuring the sealing of the connection and preventing water leakage.

[0046] The communication valve 7000 is provided with a plunger pin 7001, and the distribution pipe 2000 is provided with a positioning part 2002. The outer diameter of the positioning part 2002 is matched with the inner diameter of the through hole inside the communication valve 7000, which can smoothly extend into the inside of the communication valve 7000. A recess groove is opened on the outer wall of the positioning part 2002, and the size of the recess groove is matched with the size of the end of the plunger pin 7001.

[0047] The plunger pin 7001 is installed on the communication valve 7000 through a rotating seat, and the rotating seat is provided with an axis hole, and the plunger pin 7001 passes through the axis hole and can rotate around the center of the axis hole. When it is needed to connect and fix the distribution pipe 2000 with the main water pipe 1000, the positioning part 2002 is first inserted into the inside of the communication valve 7000, at which time the operator manually rotates the plunger pin 7001, so that the end thereof is aligned with the recess groove on the positioning part 2002 and is inserted. After insertion, the plunger pin 7001 limits the positioning part 2002 in the communication valve 7000, preventing the displacement or falling of the distribution pipe 2000 under the impact of water flow and the like, ensuring the stability and reliability of the connection of the main water pipe 1000 with the distribution pipe 2000, and further ensuring the normal operation of the entire lifting water spraying mechanism.

[0048] When daily maintenance or disassembly of the distribution pipe 2000 is needed, the operator only needs to reversely rotate the plunger pin 7001, so that the end thereof is withdrawn from the recess groove, so that the positioning part 2002 can be easily extracted from the inside of the communication valve 7000, and the disassembly and installation operation of the distribution pipe 2000 can be conveniently and quickly completed.

[0049] In some embodiments of the present application, when the distribution pipe 2000 is set up, the first pipe segment and the second pipe segment are connected together through a suitable connection method such as welding, flange connection, etc., to ensure that the internal spaces of the two are in communication with each other, forming a curved pipe structure, which in some embodiments is a U-shaped structure. During the connection process, the sealing property of the connection part needs to be ensured to prevent water leakage. A plurality of assembly ports 2001 are uniformly or according to actual needs arranged on the first pipe segment and the second pipe segment, so as to install the spray head 3000. At the same time, the distribution pipe 2000 is connected with the main water pipe 1000 through the communication valve 7000, to ensure that the water flow can smoothly flow from the main water pipe 1000 into the distribution pipe 2000. When installing, the orientation and position of the U-shaped pipe should be reasonably planned, so that the U-shaped opening accurately corresponds to the water spraying space that needs to be sprayed, wherein the water spraying space refers to the space formed by the half-encircling of the opening of the curved pipe. When actually spraying water, the spray will be generated in the water spraying space.

[0050] The entire lifting water spraying mechanism is installed at a suitable position of the grinding machine, to ensure that the opening of the U-shaped distribution pipe 2000 accurately aligns with the grinding position of the grinding wheel. Generally, a special mounting seat can be arranged on the grinding machine bed or related support, and the movable guide rail 5000 is fixed on the mounting seat by using bolts, nuts, etc., so that the entire lifting water spraying mechanism is stably installed on the grinding machine.

[0051] According to the actual height of the grinding wheel, the movable block 4000 is driven to move on the movable guide rail 5000 by a driving device such as a motor, a screw nut mechanism, etc., to adjust the height of the main water pipe 1000, the distribution pipe 2000 and the spray head 3000, so that the spray head 3000 can accurately spray towards the grinding position of the grinding wheel. During the adjustment process, some positioning devices or scale markings can be arranged to facilitate the operator to accurately adjust to the appropriate height.

[0052] The orientation of the spray head 3000 is adjusted by using the adjusting connecting piece 6000 according to the shape of the grinding wheel, the rotation direction and the grinding process requirements. For example, for grinding wheels of different diameters, the angle of the spray head 3000 needs to be adjusted accordingly to ensure that the cooling liquid can be accurately sprayed to the grinding position. The rotating joint on the adjusting connecting piece 6000 can be manually operated, or some automatic angle adjusting device can be used to accurately adjust according to the preset program.

[0053] In some embodiments of the present application, part of the second connecting pipe 6002 extends into the interior of the first connecting pipe 6001, so that a certain degree of expansion and rotation adjustment can be achieved between the second connecting pipe 6002 and the first connecting pipe 6001. A first fastening nut 6004 is sleeved on the outer wall of the first connecting pipe 6001, and the outer walls of the first connecting pipe 6001 and the second connecting pipe 6002 are provided with external threads matched with the first fastening nut 6004 at corresponding positions. When it is necessary to adjust the position and angle of the second connecting pipe 6002 relative to the first connecting pipe 6001, the first fastening nut 6004 is loosened first, at which time the second connecting pipe 6002 can slide in the first connecting pipe 6001 to change the extension length, and also can be rotated by a certain angle. After being adjusted to a suitable position and angle, the first fastening nut 6004 is tightened, which cooperates with the outer wall of the first connecting pipe 6001 and the outer wall of the second connecting pipe 6002 to generate radial pressure, so as to position the second connecting pipe 6002 relative to the first connecting pipe 6001, and ensure the stability of the position of the two pipes during water spraying.

[0054] After part of the second connecting pipe 6002 is rotationally connected to the second end of the first connecting pipe 6001 in the above manner, not only can it move with the swing of the first connecting pipe 6001, but also can rotate up and down at the position connected with the first connecting pipe 6001, further increasing the adjustable angle range.

[0055] Part of the third connecting pipe 6003 extends into the interior of the second connecting pipe 6002, and similarly, the outer walls of the second connecting pipe 6002 and the third connecting pipe 6003 are provided with external threads matched with a second fastening nut 6005 at corresponding positions. The second fastening nut 6005 is sleeved on the outer wall of the second connecting pipe 6002, and when it is necessary to adjust the position and angle of the third connecting pipe 6003 relative to the second connecting pipe 6002, the second fastening nut 6005 is loosened first, at which time the third connecting pipe 6003 can slide and rotate in the second connecting pipe 6002. After being adjusted to a suitable state, the second fastening nut 6005 is tightened, which cooperates with the outer wall of the second connecting pipe 6002 and the outer wall of the third connecting pipe 6003 to position the third connecting pipe 6003 relative to the second connecting pipe 6002.

[0056] The spray head 3000 is assembled on the third connecting pipe 6003 by threaded connection. In this way, the spray head 3000 can rotate together with the third connecting pipe 6003, and different types of spray heads 3000 can be replaced to adapt to different water spraying requirements, such as fan-shaped spray heads, conical spray heads, etc.

[0057] The internal space of the first connecting pipe 6001, the second connecting pipe 6002, the third connecting pipe 6003 and the spray head 3000 are sequentially communicated. In order to ensure the sealing of the connection, a rubber sealing ring is used for sealing at each connection position. For example, an O-shaped rubber sealing ring is installed at the rotating connection between the first connecting pipe 6001 and the second connecting pipe 6002 to prevent water leakage. The beneficial effects brought by such a design are significant. The multiple rotating connection points and the design of the telescopic adjustment greatly improve the flexibility of the orientation and position adjustment of the spray head 3000. The operator can accurately adjust the orientation and position of the spray head 3000 according to the actual scene, such as different shapes of the site, different distribution of the water spraying area, etc., so that the water spraying coverage is more reasonable, the water spraying demand in various complex scenes is met, and the efficiency and effect of the water spraying operation are improved. Secondly, the design of the internal space sequentially communicated ensures the stability of the water flow transmission, and the normal spraying of the water flow is not affected by the structure of the connecting piece, ensuring the overall performance of the lifting water spraying mechanism.

[0058] In some embodiments of the present application, the first end of the first connecting pipe 6001 is detachably connected to the assembly port 2001. According to the length of the distribution pipe 2000 and the number of assembly ports 2001 to be set, the interval distance between each assembly port 2001 is calculated to ensure equal intervals for uniform distribution. In the manufacturing process of the distribution pipe 2000, a specially designed mold is used, and the positions and shapes of the assembly ports 2001 are set on the mold according to the requirement of uniform distribution. The distribution pipe 2000 with uniformly distributed assembly ports 2001 is manufactured by one-time molding, ensuring the accuracy and consistency of the positions of the assembly ports 2001.

[0059] The spray head 3000 connected to the assembly port 2001 can uniformly spray water below the distribution pipe 2000, providing more uniform and comprehensive water spraying coverage to the parts below, such as grinding wheels, which need to be cooled or cleaned, improving the cooling and cleaning effect, avoiding the occurrence of local overheating or incomplete cleaning, and ensuring the quality and efficiency of the grinding work.

[0060] The uniformly distributed assembly ports 2001 make the distribution pipe 2000 receive more balanced forces such as water flow pressure during water spraying, reducing problems such as pipe deformation and vibration caused by uneven stress, which is beneficial to prolong the service life of the distribution pipe 2000 and improve the stability and reliability of the entire water spraying system.

[0061] In some embodiments of the present application, the movable block 4000 comprises an assemblable first part and a second part; the main water pipe 1000 is clamped in the fitting groove formed by the first part and the second part. The first part and the second part are both designed as half-groove structures matching the outer contour of the main water pipe 1000, and after splicing, they can form a complete fitting groove wrapping the main water pipe 1000. For example, according to the circular cross-section of the main water pipe 1000, the fitting surfaces of the first and second parts are designed as semicircular grooves respectively to ensure close fitting.

[0062] Corresponding connecting structures such as bolt holes, buckles or dovetail grooves are provided on the edges of the first and second parts. When using bolt connection, bolt holes are drilled at corresponding positions of the two parts, and by inserting bolts and tightening nuts, the two parts are fixed together, thereby firmly clamping the main water pipe 1000 in the fitting groove; if buckles are used for connection, a protruding buckle is provided on the first part and a corresponding buckle slot is provided on the second part, and during installation, the buckle is inserted into the buckle slot; for dovetail groove connection, a dovetail-shaped protrusion is processed on the first part and a matching dovetail groove is processed on the second part, and during assembly, the protrusion is slid into the dovetail groove and fixed.

[0063] The movable block 4000 assembled and clamping the main water pipe 1000 is installed on the movable guide rail 5000. By adjusting the position of the movable block 4000 on the guide rail, the height of the main water pipe 1000 and the distribution pipe 2000 and the spray head 3000 are determined, and at the same time, the connecting structure between the movable block 4000 and the guide rail, such as the cooperation of the slider and the guide rail, ensures that the movable block 4000 can smoothly move up and down along the guide rail.

[0064] The movable block 4000 adopts a two-part structure that can be assembled, which facilitates the installation and disassembly of the main water pipe 1000. When installing the main water pipe 1000, it can be placed in the fitting groove without complicated operation, and then the movable block 4000 is assembled; when repairing or replacing the main water pipe 1000, the movable block 4000 can also be easily disassembled, improving the maintenance efficiency and reducing downtime.

[0065] In some embodiments of the present application, the top of the main water pipe 1000 is provided with a liquid opening. The liquid opening can be designed in a circular, square or elliptical shape. The circular opening is relatively simple to process and has less resistance when fluid passes through; the square opening is convenient for docking with some specific-shaped liquid input devices; the elliptical opening can take into account the characteristics of circular and square openings to some extent, and the appropriate shape can be selected according to specific needs.

[0066] To facilitate connection with the liquid supply device, a threaded connection, flange connection or quick connector can be provided at the opening. Threaded connection is suitable for smaller pipe diameter and lower pressure, simple operation and good sealing; flange connection is suitable for larger pipe diameter and higher pressure system, firm connection and reliable sealing; quick connector is convenient and fast, can realize quick disassembly and assembly, suitable for frequent replacement of liquid supply source or maintenance operation.

[0067] Reference is made to the accompanying drawings Figure 6 , Figure 6 The assembly schematic diagram of the lifting water spraying mechanism provided by the embodiment of the application is assembled on a grinding machine. The vertical grinding machine shown includes a rotating main shaft 8000 and a grinding head; the grinding head is arranged at the end of the rotating main shaft 8000 and completes rotary grinding under the driving of the rotating main shaft 8000,

[0068] The lifting water spraying mechanism is installed on the bed of the vertical grinding machine or a special support, ensuring that the whole mechanism is stable and does not interfere with the normal operation of other parts of the grinding machine. The movable guide rail 5000 is fixed to the bed of the grinding machine by bolt connection or welding, providing stable support for the lifting movement of the water spraying mechanism.

[0069] According to different working heights of the grinding head, the movable block 4000 is moved on the movable guide rail 5000 by the driving device. The driving device can be a motor cooperating with a screw nut mechanism. The rotation of the screw is controlled by the forward and reverse rotation of the motor, so that the nut drives the movable block 4000 to move up and down, thereby accurately adjusting the height of the main water pipe 1000, the distribution pipe 2000 and the nozzle 3000, so that the nozzle 3000 is always aligned with the grinding position of the grinding head.

[0070] The angle of the nozzle 3000 is adjusted by the adjusting connecting piece 6000. Since the adjusting connecting piece 6000 includes a first connecting pipe 6001, a second connecting pipe 6002 and a third connecting pipe 6003, the first connecting pipe 6001 is rotationally connected to the assembly port 2001, the second connecting pipe 6002 is rotationally connected to the first connecting pipe 6001, and the third connecting pipe 6003 is rotationally connected to the end of the second connecting pipe 6002 and the nozzle 3000 is assembled on the third connecting pipe 6003. The operator can manually or through an automatic device adjust these rotationally connected parts according to the shape of the grinding head, the direction of rotation and the grinding process requirements, so that the nozzle 3000 can spray water to the grinding position at the best angle.

[0071] The high-speed jet stream of water can timely flush away the debris generated by grinding, avoiding the accumulation of debris in the grinding area. The accumulated debris may scratch the surface of the workpiece and affect the grinding accuracy. By spraying water to clean the debris, the smooth progress of the grinding work is ensured and the machining accuracy is improved.

[0072] The height of the lifting water spraying mechanism and the angle of the nozzle 3000 can be adjusted, which can adapt to different specifications of the grinding head and various grinding process requirements. Whether it is small precision grinding or large rough grinding, the water spraying system can be adjusted to the best working state, improving the versatility and applicability of the vertical grinding machine. The nozzle 3000 can accurately spray water to the grinding position of the grinding head, so that the coolant fully covers the grinding point, effectively removes a large amount of heat generated during grinding, prevents the grinding head and workpiece from being damaged due to overheating, and improves the service life of the grinding head and the machining quality of the workpiece.

[0073] The technical features of the above embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered as within the scope of the present disclosure.

[0074] The above embodiments only express several implementation manners of the present application, and the description is specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the scope of the present application. Therefore, the scope of the patent protection of the present application should be subject to the appended claims.
