Description

Technical Field

[0001] The invention relates to the technical field of self-priming pump casing processing, in particular to a self-priming pump casing processing device. Background Art

[0002] On existing production lines for intelligent manufacturing equipment for processing self-priming pump casings, the cutting tool rotates at high speed in a fixed position. Because the equipment structure lacks a provision for localized negative pressure or a diversion and collection unit, the fine-grained metal debris produced by cutting is primarily flung around by centrifugal force or randomly settles on the machine table, guide rails, tool guards, and surrounding workpieces. Over extended periods of operation, the debris adheres to the lead screw, linear guide rails, and lubricant film surfaces, causing accelerated wear of the kinematic pairs, reduced positioning accuracy, and even seizure and failure. Frequent downtime for cleaning and recalibration is required, increasing the machine's non-productive hours.

[0003] More seriously, metal debris, spun by turbulent air, forms floating particles. Inhalable particles smaller than 10 μm can enter the operator's lungs through the respiratory tract, causing occupational diseases such as chronic pneumoconiosis and metal fume fever. Larger fragments can be ejected at high speed, injuring the operator's eyes and face or lacer their skin, requiring them to wear heavy masks and protective gloves to operate. Furthermore, hot debris coming into contact with engine oil and coolant easily produces smoke and pungent odors, placing higher demands on workshop ventilation and fire protection.

[0031] The working principle of a self-priming pump casing processing device disclosed in the present invention is as follows: the flange of the self-priming pump casing is placed on the fixed table 128, and the telescopic rod of the clamping and regulating electric cylinder 137 is controlled to adjust the telescopic rod of the clamping and regulating electric cylinder 137 through two clamping and regulating connecting rods 138 to adjust the two clamping sliding blocks 139 to align with the mounting holes of the flange. Before that, a stud 140 of appropriate size is selected according to the diameter of the mounting holes of different flanges, and it is installed on the clamping sliding block 139, and then the flange is fixed to the fixed table 128 by the nut 141 and the stud 140. According to the processing position, the placement position of the self-priming pump casing is adjusted midway. The self-priming pump has at least two flanges. The placement position of the self-priming pump casing on the fixed table 128 can be selected by fixing the flanges in different positions. The bottom servo motor 130 and the top servo motor 131 control the corresponding bottom screw rod 132 and top screw rod 133. The bottom screw rod 132 is used to drive the translation top frame 127 to slide on the bottom guide slide 134, and the top screw rod 133 is used to drive the fixed table 128 to slide on the top guide slide 135, and the displacement directions of the two are perpendicular. Horizontal displacement of the self-priming pump housing is achieved. The output shaft of the rotary drive motor 144 is controlled, and the output shaft of the rotary drive motor 144 drives the input shaft of the rotary drive gearbox 145 to rotate. The output shaft of the rotary drive gearbox 145 drives the mobile platform on the rotary support disk 142 to rotate, thereby driving the self-priming pump housing to be processed to rotate.

[0032] By driving the tool 113 to rotate, the tool 113 contacts the inner wall of the self-priming pump housing, and the self-priming pump housing rotates, the feed turning inside the self-priming pump housing is realized, wherein the rotation of the tool 113 combined with the self-rotation of the self-priming pump housing can improve the efficiency of the self-priming pump housing turning process, and increase the linear speed of the contact surface. Specifically, the drive motor 119 is started, and the output shaft of the drive motor 119 drives the drive gear 120 to rotate, and the drive gear 120 drives the gear ring sleeve 121 to rotate, and the gear ring sleeve 121 drives the outer ring gear 125 to rotate synchronously, and the outer ring gear 125 drives the center spline gear 123 to rotate through the planetary gear 124. During this process, if the electromagnet 118 is in a completely unpowered state at this time, the friction between the electromagnet 118 and the planetary gear mounting plate 122 is only provided by the gravity of the electromagnet 118 itself, that is, the planetary gear mounting plate 122 can rotate. , the planetary gear mounting plate 122 can rotate, which means that the planetary gear 124 installed on the planetary gear mounting plate 122 can revolve. Therefore, when the outer ring gear 125 drives the center spline gear 123 to rotate through the planetary gear 124, the planetary gear 124 will also revolve, which releases part of the power. At this time, the transmission ratio between the outer ring gear 125 and the center spline gear 123 is the lowest. By controlling the size of the magnetic force of the electromagnet 118, the size of the friction between the electromagnet 118 and the planetary gear mounting plate 122 can be controlled, thereby controlling the planetary gear The revolution speed of the wheel 124 controls the transmission ratio between the center spline gear 123 and the outer ring gear 125, thereby realizing the control of the rotation speed of the center spline gear 123. The rotation speed of the center spline gear 123 is the same as that of the spline shaft 116, which controls the rotation speed of the booster blade 111 on the tool rod 112. The rotation of the booster blade 111 will generate a downward thrust, causing the tool rod 112 to move downward, controlling the tool 113 to contact with the self-priming pump housing, and realizing the turning feed. At the same time, due to the downward thrust generated by the booster blade 111 Because of the negative pressure, the area below the booster blades 111 is in a negative pressure state, and the debris separated from the self-priming pump housing is sucked into the booster hood pipe 109, and then guided to the inside of the top collection tower 102 through the tapered bellows 108 (the top collection tower 102 is connected to the purifier through a pipe to filter debris from the inhaled air. At the same time, as time goes by, some debris will accumulate on the top panel 104. Therefore, it is necessary to use an easy-to-disassemble installation method between the top collection tower 102 and the housing 101, and regularly clean the top panel 104). If the angle of the tool 113 for turning the self-priming pump housing is adjusted, it is necessary to control the outer adjustment electric cylinder 106 and the inner adjustment electric cylinder 115. The outer adjustment electric cylinder 106 and the inner adjustment electric cylinder 115 respectively drive the tool rod 112 to swing along the rotating axis in different directions for processing different positions.As the speed of the booster blade 111 increases, the thrust generated increases, and the booster blade 111 will overcome the elastic force of the spring 129 and move downward (that is, move toward the self-priming pump housing). When the thrust generated by the booster blade 111 is the same as the elastic force of the spring 129, the booster blade 111 will no longer move. If it is greater than the elastic force of the spring 129, it will continue to move downward, otherwise it will reset upward.
