Detailed implementation manners
[0033] Example 1: Refer to Figure 1-Figure 8A spraying pre-treatment device for steel frame bed manufacturing includes a base 1, on which a steel pipe body 2 is placed for horizontal rotation. Polishing discs 3 are obliquely arranged on both sides of the steel pipe body 2. The end faces of the polishing discs 3 are in contact with the surface of the steel pipe body 2. A water spray pipe 4 is arranged above the polishing disc 3. A fixing sleeve 5 is fixed to one end of the outer wall of the water spray pipe 4 facing the polishing disc 3. A water spray disc 6 with a disc-shaped structure is rotatably arranged in the fixing sleeve 5. The circumferential outer wall of the water spray disc 6 is provided with water spray ports 601 distributed in a ring array. The end of the water spray pipe 4 is connected to the inside of the water spray disc 6. The water spray disc 6 is provided with a rotating hole at the center position of the end of the water spray pipe 4. The inner wall of the rotating hole is in sliding contact with the outer wall of the water spray pipe 4. The water spray disc 6 is away from the water spray pipe 4. A shaft 7 is fixed to the inner wall at one end, and a plurality of blades 8 are installed on the outer wall of the shaft 7. The fixed sleeve 5 is set to open on one side of the polishing disc 3, and the opening of the fixed sleeve 5 is facing the contact position between the polishing disc 3 and the steel pipe body 2. When in use, the steel pipe body 2 is rotated and the polishing disc 3 is moved along the axial direction of the steel pipe body 2, so that the surface of the steel pipe body 2 is polished by the polishing discs 3 on both sides. The water spray pipe 4 and the water spray disc 6 located above the polishing disc 3 move with the polishing disc 3, and a water pump is connected to the end of the water spray pipe 4 away from the water spray disc 6 so that the water spray port 601 on the periphery of the water spray disc 6 sprays water outward, and the water spray pipe 4 and the fixed sleeve 5 are fixedly arranged, which means that the opening of the fixed sleeve 5 is always facing the polishing disc The contact position between the optical disc 3 and the steel pipe body 2 is made so that the water spraying ports 601 corresponding to the opening of the outer wall of the water spraying plate 6 are sprayed toward the contact position between the polishing disc 3 and the steel pipe body 2 for cleaning, and through the rotation setting of the water spraying plate 6 relative to the water spraying pipe 4 and the fixed sleeve 5 and the setting of the blade 8, the water flow entering the water spraying plate 6 through the water spraying pipe 4 hits the blade 8, so that the water spraying plate 6 is rotated relative to the fixed sleeve 5, that is, the water spraying ports 601 distributed on the outer wall of the water spraying plate 6 are alternately rotated to the opening position of the fixed sleeve 5 to spray water outward. On the one hand, the water spraying plate 6 sprays water during the continuous rotation process, so that the water spraying ports 601 corresponding to the opening of the outer wall of the water spraying plate 6 are in a circular motion, so that the sprayed water flow or The water mist is in an inclined motion state, so that the direction of the water flow sprayed toward the contact position between the polishing disk 3 and the steel pipe body 2 is constantly changing, thereby improving the effect of clearing out the debris. Compared with the conventional means of single-direction flushing, which may cause some debris to be mixed in the contact position, this method effectively improves the effect of flushing the debris out of the surface of the polishing disk 3 by constantly changing direction; on the other hand, by spraying water on the outer wall of the water spray disk 6 and rotating it at the same time, the position of the water spray port 601 is constantly changing, avoiding always fixing the position facing the polishing disk 3, and avoiding part of the debris splashing on the surface around the water spray port 601 during long-term use, affecting the water spraying operation, thereby improving the cleaning of the water spray port 601 position to improve the effectiveness of long-term polishing and flushing.
[0034] In the present invention, support frames 16 are installed at both ends of the top of the base 1. The support frames 16 are provided with circular grooves, and a turntable 17 is rotatably connected to the inner wall of the circular groove. A clamping mechanism is installed in the turntable 17. A motor 18 is installed below one of the support frames 16. A gear 19 is fixed to the output shaft of the motor 18. Tooth grooves meshing with the gear 19 are provided on the outer wall of the turntable 17. It should be noted that: an annular groove is provided at the middle position of the circumferential outer wall of the turntable 17, and the inner wall of the annular groove is in sliding contact with the inner wall of the circular groove. Limiting disks are provided at both ends of the turntable 17 located in the annular groove. The outer diameter of the limiting disks is larger than the inner wall of the annular groove, and tooth grooves distributed in an annular array are provided on the outer wall of the limiting disks at the positions corresponding to the gear 19. Thus, after the steel pipe main body 2 is horizontally clamped and fixed, the motor 18 drives the turntable 17 and the steel pipe main body 2 to rotate along the horizontal axis, and the stability of the rotation of the turntable 17 with the clamping mechanism and the steel pipe main body 2 is ensured by the annular groove provided in the middle of the turntable 17.
[0035] In the present invention, the clamping mechanism is provided with a hydraulic telescopic rod 20 horizontally installed on the turntable 17. A positioning groove is provided at the position of the turntable 17 corresponding to the hydraulic telescopic rod 20.

A connecting column 22 is installed at one end of the connecting plate 21 facing the hydraulic telescopic rod 20. A sliding groove is provided at the position of the outer wall of the turntable 17 corresponding to the connecting column 22. The outer wall of the connecting column 22 is in sliding contact with the inner wall of the sliding groove. A pressing block 23 is fixed to one end of the connecting column 22 facing the steel pipe main body 2. The clamping or loosening operation of the pressing blocks 23 at both ends on the steel pipe main body 2 is realized through the telescopic operation of the hydraulic telescopic rod 20.
[0036] In the present invention, electric guide rails 11 are installed on both sides of the top of the base 1. The electric guide rails 11 are arranged parallel to the steel pipe main body 2. An installation frame 12 is connected to the electric guide rails 11. One end of the polishing disc 3 away from the steel pipe main body 2 is connected with a hydraulic rod 10. Both the hydraulic rod 10 and the water spray pipe 4 are connected to the corresponding installation frame 12. The hydraulic rod 10 is inclined upward in the direction approaching the steel pipe main body 2. Thus, during the rotation of the steel pipe main body 2, the polishing disc 3 and the corresponding water spray pipe 4 are moved in the axial direction by the electric guide rails 11 to ensure the polishing operation of each position of the steel pipe main body 2, and the position of the polishing disc 3 can be adjusted by the hydraulic rod 10 to contact the surface of the steel pipe main body 2.
[0037] In the present invention, a connecting block 9 with a circular cross-section is fixed to one end of the hydraulic rod 10 facing the polishing disc 3, a connecting groove is provided at the end of the polishing disc 3 facing the connecting block 9, the inner wall of the connecting groove is rotatably connected to the connecting block 9 through a bearing, and a guide groove 301 distributed in an annular manner is provided on the circumferential outer wall of the polishing disc 3. In actual use, through the rotation setting of the polishing disc 3 and the connecting block 9, when debris is squeezed and mixed at the position where the polishing disc 3 contacts the surface of the steel pipe body 2, the extrusion force at the contact position between the polishing disc 3 and the steel pipe body 2 will be unbalanced, and the polishing disc 3 will rotate relative to the connecting block 9 during the movement of the polishing disc 3, thereby separating the squeezed and mixed debris and cooperating with water spraying to improve the debris removal effect, and the water flow sprayed from the water spray disc 6 position partially hits the guide groove 301 on the outer wall of the polishing disc 3 to ensure the rotation operation effect of the polishing disc 3 relative to the steel pipe body 2, thereby cooperating with the deflection movement of the water spray port 601 while spraying water to further improve the flushing and cleaning effect and efficiency of the contact position between the polishing disc 3 and the steel pipe body 2.
[0038] In the present invention, a mounting groove 121 is provided above the mounting frame 12, and the hydraulic rod 10 is fixedly installed on the inner wall of the mounting groove 121, and rotating blocks 401 are fixed on the outer walls of both sides of the water spray pipe 4, and rotating cylinders are provided at positions corresponding to the inner wall of the mounting groove 121 and the rotating block 401, and the outer wall of the rotating block 401 is rotatably connected with the inner wall of the rotating cylinder, and a guide pipe 13 is installed on the side of the mounting frame 12 facing the steel pipe main body 2, and a fixing frame 14 is fixed between the guide pipe 13 and the mounting frame 12, and a spring 15 is slidingly provided on the inner wall of the guide pipe 13, one end of the spring 15 is fixed between the end of the connecting block 9 close to the hydraulic rod 10, and the other end of the spring 15 is fixed to the bottom of the water spray pipe 4, and the guide pipe 13 consists of a vertical part and an inclined part, and the inclined part is connected to the bottom end of the vertical part, and the inclined part is arranged parallel to the hydraulic rod 10, and in the process of polishing by contacting the polishing disc 3 with the surface of the steel pipe main body 2 for polishing, the spring 15 is used to auxiliary support the water spray pipe 4, and the steel pipe main body 2 and the polishing process are in progress. The friction between the disks 3 generates mechanical vibration, which is transmitted to the position of the rotating water spray pipe 4 through the spring 15, so that the water spray disk 6 is tilted and reciprocatingly swung to improve the effect of changing the direction of water spraying from the water nozzle 601 toward the polishing disk 3 and the steel pipe body 2, so that the debris mixed in the contact position is effectively flushed out through the changing water spray and the subsequent speed change rotation of the polishing disk 3, thereby improving the polishing operation effect; after the polishing contact, the hydraulic rod 10 can be used to move the polishing disk 3 away from the steel pipe body 2, so that the polishing disk 3 moves back and forth at a position where it does not contact the steel pipe body 2, so that the water spray disk 6 swings back and forth to spray water to improve the cleaning effect of the steel pipe body 2 after polishing; after the polishing and tilting are completed, the water spray pipe 4 is replaced and connected to the fan to blow and air-dry the steel pipe body 2 during the reciprocating swing of the water spray disk 6; thereby, the connection setting of the polishing disk 3 and the water spray pipe 4 effectively improves the pre-treatment operation effect and work efficiency of polishing, cleaning and air drying.
[0039] Example 2: Refer to Figure 1-Figure 8 , a pre-spraying treatment device for manufacturing a steel frame bed. On the basis of Example 1, a pressure monitoring module is arranged between the hydraulic rod 10 and the connecting block 9. The pressure monitoring module is used to monitor the extrusion force between the telescopic rod of the hydraulic rod 10 and the connecting block 9 in real time. It should be noted that: the pressure monitoring module can adopt a pressure sensor; the larger the pressure value may indicate that there are debris between the polishing disc 3 and the steel pipe main body 2 that have not been cleared, and the staff needs to be reminded to clean manually or increase the water spraying intensity; an angle monitoring module corresponding to the position of the water spraying pipe 4 is arranged on the mounting frame 12. The angle monitoring module is used to monitor the deflection angle of the water spraying pipe 4 in real time. It should be noted that: the angle monitoring module is used to monitor the deflection angle of the water spraying pipe 4 relative to the normal state during the polishing movement. The angle monitoring module can choose to adopt an angle monitor to monitor the deflection angle of the rotating block 401, or the angle monitoring module can also choose to adopt a distance sensor arranged in the mounting groove 121, and calculate the deflection angle by monitoring the change in the distance from the water spraying pipe 4. The means of angle monitoring can adopt conventional means in the prior art and will not be described in detail; the larger the rotation angle of the water spraying pipe 4, the greater the surface vibration amplitude, which may be due to the debris between the polishing disc 3 and the steel pipe main body 2 that have not been cleared, and the staff needs to be reminded to clean manually or increase the water spraying intensity.
[0040] In the present invention, the pressure monitoring module and the angle monitoring module are uploaded to the central processing unit, and the processing logic is as follows:
[0041] Step 1, data acquisition: In a fixed data acquisition period Δt, the pressure monitoring module obtains the pressure value in real time and saves it as a pressure value sequence {F1, F2,... F m}, and the angle monitoring module obtains the deflection angle of the water spraying pipe 4 in real time and saves it as an angle deviation value sequence {θ1, θ2,... θ m}, where m represents the number of data points collected;
[0042] Step 2, data screening: Pressure value screening, a pressure threshold F s and a duration threshold T s are preset. Traverse the pressure value sequence. When it is monitored that the pressure value exceeds F s , record the start timestamp, and continuously monitor the subsequent collected pressure values starting from the start timestamp. If the pressure value is always greater than F s within the time of T s , then the pressure data within this period is included in the subsequent calculation, and the average pressure value of this period is calculated as the effective pressure value;
[0043] Angle deviation value screening, set an angle deviation threshold θ s, taking the acquisition period Δt as the unit, scan the sequence of angle deviation values. When the angle deviation value exceeds θ s , record this data point and its timestamp, and check whether the angle deviation value exceeds θ again within the next two acquisition periods s . If it occurs, include the angle deviation data exceeding θ within these three periods s in the calculation, and calculate the average angle of these data as the effective angle deviation value;
[0044] Thus, the effectiveness and accuracy of monitoring and control are improved through the above data screening;
[0045] Step Three: Calculate the evaluation coefficient: Preset the upper limit F of the maximum pressure max and the upper limit θ of the maximum angle deviation max , and calculate the evaluation coefficient E, where ω1 and ω2 are preset weight coefficients, and ω1 + ω2 = 1. Among them, through and the normalization processing of the pressure value and the angle deviation value, the influence of the dimension is eliminated, and the rationality of the overall evaluation coefficient extreme and the effectiveness of judgment are improved;
[0046] Step Four: Control logic: When the calculated evaluation coefficient is less than or equal to the preset reference coefficient, the device maintains the current operation and continues data acquisition and monitoring;
[0047] When the evaluation coefficient is greater than the preset reference coefficient, it indicates that there may be debris between the polishing disc 3 and the steel pipe body 2 and it cannot be effectively cleared, reminding the staff or automatically adjusting the water spraying intensity;
[0048] Through the monitoring of the pressure value and the angle value, the contact polishing work between the polishing disc 3 and the steel pipe body 2 is effectively monitored, and timely reminder is given when there is debris squeezed in, avoiding the expansion of the influence, so as to improve the actual long-term polishing operation effect.
[0049] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.

The spraying pre-treatment device for steel frame bed manufacturing according to claim 9, characterized in that: Upload the pressure monitoring module and angle monitoring module to the central processing, and the processing logic is: Step 1: In a fixed data acquisition period Δt, the pressure monitoring module obtains the pressure value in real time and saves it as a pressure value sequence {F1, F2, ... F m }, the angle monitoring module obtains the deflection angle of the water spray pipe (4) in real time and saves it as an angle deviation value sequence {θ1,θ2,…θ m }, where m represents the number of collected data points; Step 2: Preset the pressure threshold F s and duration threshold T s , traverse the pressure value sequence, when the pressure value exceeds F s When T s The pressure value is always greater than F during the time s , the pressure data during this period will be included in the subsequent calculation, and the average pressure value during this period will be calculated As the effective pressure value; Set the angle deviation threshold θ s , taking the acquisition period Δt as the unit, the angle deviation value sequence is scanned. When the angle deviation value exceeds θ s When the data point and its timestamp are recorded, check whether the angle deviation value exceeds θ again in the next two acquisition cycles. s If the situation occurs, the three cycles will exceed θ s The angle deviation data is taken into account and the average angle of these data is calculated. As the effective angle deviation value; Step 3: Preset the maximum pressure limit F max and the maximum upper limit of the angle deviation θ max , calculate the evaluation coefficient E, Wherein ω1 and ω2 are preset weight coefficients, and ω1+ω2=1; Step 4: When the calculated evaluation coefficient is less than or equal to the preset reference coefficient, the device maintains the current operation and continues to collect and monitor data; When the evaluation coefficient is greater than the preset reference coefficient, it indicates that debris may be mixed between the polishing disc (3) and the steel pipe body (2) and cannot be effectively cleared out.
