[0002] A horizontal multistage pump is a delivery pump based on the principle of centrifugal force. It is often used in various long-distance water transportation. It has the characteristics of high efficiency, long life, and a wide range of performance. It is often driven directly by a motor to obtain maximum power. The pump body is the main load-bearing and closing device of the entire pump. Many parts need to be installed inside. After the pump body is cast, it needs to be further processed to meet the subsequent assembly. Grooving is an important part of the pump body processing. The automatic processing device for pump bodies in the existing technology cannot realize the installation and fixation of the processed parts, and the degree of automation is poor.

[0004] Furthermore, the conveying mechanism also includes a power motor, a motor gear is fixedly installed on the motor shaft of the power motor, a half-tooth gear is rotatably installed under the main frame, a docking gear is fixedly installed on the half-tooth gear, the docking gear is meshed with the motor gear, and the half-tooth gear is meshed with the shaft gear, an outer gear and an upper gear are rotatably installed on the side of the main frame, the outer gear is meshed with the half-tooth gear, a vertical transmission belt is wrapped around the outer gear and the upper gear, an inner gear is rotatably installed on the side of the main frame, a side bevel gear is fixedly installed on the inner gear, the inner gear is meshed with the upper gear, a conveying bevel gear is fixedly installed on the driving wheel located on one side of the power motor, and the conveying bevel gear is meshed with the side bevel gear.

[0005] Furthermore, a guide post spring is arranged between the guide post and the guide sliding seat, four inner clamping blocks are slidably installed in the connecting seat, and a clamping block spring is arranged between the inner clamping block and the connecting seat.

[0006] When in use, the pump body shell is placed on the connecting plate. At this time, the threaded hole on the connecting plate is aligned with the threaded hole on the pump body shell, and the pump body shell is initially limited by the frame on the shaft gear. The power motor drives the motor gear to rotate, thereby driving the docking gear and the half-tooth gear to rotate, and the half-tooth gear drives the shaft gear and the outer gear to rotate intermittently. When the half-tooth gear is meshed with the shaft gear, the half-tooth gear is not meshed with the outer gear. When the outer gear rotates, the upper gear is driven to rotate through the vertical transmission belt, and the conveying bevel gear and the driving wheel are driven to rotate through the internal gear and the side bevel gear, thereby driving the conveyor belt to move, thereby driving the connecting plate and the pump body shell to move forward once. When the connecting plate reaches the guide column, as the connecting plate continues to move forward, the guide column will enter the arc slide groove, and the guide column will slide along the arc slide groove, and cooperate with the sliding of the guide column in the guide slide seat to drive the connecting plate and the pump body shell to rotate ninety degrees.

[0009] When the half-tooth gear drives the shaft gear to rotate, it drives the long shaft, cam and working gear to rotate. At this time, the cam pushes the lifting push plate to rise, and the screwing motor rotates at the same time, driving the screw head to rotate. The screw head rotates and rises, and the connecting bolts above it in the bolt box are screwed into the screw holes of the connecting plate and the pump body shell above the connecting mechanism to achieve the connection and fixation of the connecting plate and the pump body shell. When the cam continues to rotate, the lifting push plate begins to descend under the action of gravity, and the push plate spring rebounds to push the next connecting bolt to the top of the screw head.

[0011] Furthermore, a lower hanging frame is fixedly installed below the main frame, a tightening plate is slidably installed on the lower hanging frame, a lower pressing spring is arranged between the tightening plate and the lower hanging frame, and the tightening plate contacts the lower end of the inner gear ring.

[0012] The boring frame and the slide column are fixedly installed through a polygonal groove, and the angle of the boring frame can be adjusted by changing the matching surface.

[0013] When the half-tooth gear drives the shaft gear to rotate, the working gear drives the inner gear ring to slide along the annular groove through the inner guide column. Through the sliding cooperation between the slider and the slide column, and the sliding cooperation between the slide column and the side slide frame, the slide column drives the boring tool to move inward first and then outward. The boring tool motor rotates to drive the boring tool to rotate, and the pump body shell is bored by the boring tool. Each time the half-tooth gear meshes with the shaft gear, the slide column moves inward once and resets outward. The slide columns and boring tools arranged on both sides of the main frame can reduce the inclination of the pump body shell during processing, eliminate the opposite force, improve the processing accuracy, and cooperate with the guide column to drive the rotation of the connecting plate to realize the switching of the boring processing on both sides.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) The conveying mechanism provided in the present invention can fully automatically convey the pump body, and can realize automatic steering under the action of the guide column and the arc slide groove. Through the slide columns and boring cutters provided on both sides of the main frame, the inclination of the pump body shell can be reduced during processing, the opposite forces can be eliminated, and the processing accuracy can be improved; (2) The connecting mechanism provided in the present invention can fasten the pump body shell during the conveying and processing process to the connecting plate to prevent the pump body shell from vibrating too much during the conveying and processing process, thereby affecting the processing accuracy; (3) The half-tooth gear provided in the present invention drives the shaft gear and the external gear to rotate intermittently, thereby realizing that the pump body shell is not processed and connected during movement.

At this time, the threaded holes on the connecting plate 119 are aligned with the threaded holes on the pump body shell 4, and the pump body shell 4 is initially limited by the frame on the shaft gear 110. The power motor 102 drives the motor gear 106 to rotate, thereby driving the docking gear 107 and the half-toothed gear 108 to rotate. The half-toothed gear 108 drives the shaft gear 110 and the outer gear 113 to rotate intermittently. When the half-toothed gear 108 is meshed with the shaft gear 110, the half-toothed gear 108 is not meshed with the outer gear 113.

[0024] When the half-tooth gear 108 drives the shaft gear 110 to rotate, it drives the long shaft 109, the cam 111 and the working gear 112 to rotate. At this time, the cam 111 pushes the lifting push plate 205 to rise, and at the same time, the screwing motor 206 rotates, driving the screw head 207 to rotate. The screw head 207 rotates and rises, and the connecting bolt 204 above it in the bolt box 201 is screwed into the connecting disk 119 located above the connecting mechanism and the screw hole of the pump body shell 4, so as to realize the connection and fixation of the connecting disk 119 and the pump body shell 4. When the cam 111 continues to rotate, the lifting push plate 205 begins to descend under the action of gravity, and the push plate spring 203 rebounds, pushing the next connecting bolt 204 to the top of the screw head 207.

[0028] When the half-toothed gear 108 drives the shaft gear 110 to rotate, the working gear 112 drives the inner gear ring 310 to slide along the annular groove 307 through the inner guide column 308. Through the sliding cooperation between the slider 311 and the slide column 302, and the sliding cooperation between the slide column 302 and the side slide frame 301, the slide column 302 moves inward with the boring tool 305 first, and then moves outward. The boring tool motor 304 rotates to drive the boring tool 305 to rotate, and the pump body shell 4 is bored by the boring tool 305. Every time the half-toothed gear 108 meshes with the shaft gear 110, the slide column 302 moves inward once and resets outward.

[0029] The working principle of the pump body grooving processing device of a horizontal multi-stage barrel pump disclosed in the present invention is as follows: when in use, the pump body shell 4 is placed on the connecting plate 119, at which time the threaded holes on the connecting plate 119 are aligned with the threaded holes on the pump body shell 4, and the pump body shell 4 is initially limited by the frame on the shaft gear 110, the power motor 102 drives the motor gear 106 to rotate, thereby driving the docking gear 107 and the half-tooth gear 108 to rotate, and the half-tooth gear 108 drives the shaft gear 110 and the outer gear 113 to rotate intermittently, when the half-tooth gear 108 is meshed with the shaft gear 110, the half-tooth gear 108 is not meshed with the outer gear 113, and when the outer gear 113 rotates, the vertical transmission Belt 114 drives the upper gear 115 to rotate, and drives the conveying bevel gear 105 and the driving wheel 103 to rotate through the internal gear 116 and the side bevel gear 117, thereby driving the conveyor belt 104 to move, thereby driving the connecting plate 119 and the pump body shell 4 to move forward once. When the connecting plate 119 reaches the guide column 123, as the connecting plate 119 continues to move forward, the guide column 123 will enter the arc slide groove 122, and the guide column 123 will slide along the arc slide groove 122, and cooperate with the sliding of the guide column 123 in the guide slide seat 124, driving the connecting plate 119 and the pump body shell 4 to rotate ninety degrees. When the connecting plate 119 and the pump body shell 4 pass two consecutive guide columns 123, they rotate one hundred and eighty degrees. When the half-tooth gear 108 drives the shaft gear 110 to rotate, it drives the long shaft 109, the cam 111 and the working gear 112 to rotate. At this time, the cam 111 pushes the lifting push plate 205 to rise, and at the same time, the screwing motor 206 rotates, driving the screw head 207 to rotate. The screw head 207 rotates and rises, and the connecting bolt 204 above it in the bolt box 201 is screwed into the connecting disk 119 located above the connecting mechanism and the screw hole of the pump body shell 4, so as to realize the connection and fixation of the connecting disk 119 and the pump body shell 4. When the cam 111 continues to rotate, the lifting push plate 205 begins to descend under the action of gravity, and the push plate spring 203 rebounds, pushing the next connecting bolt 204 to the top of the screw head 207. When the half-toothed gear 108 drives the shaft gear 110 to rotate, the working gear 112 drives the inner gear ring 310 to slide along the annular groove 307 through the inner guide column 308. Through the sliding cooperation between the slider 311 and the slide column 302, and the sliding cooperation between the slide column 302 and the side slide frame 301, the slide column 302 moves inward with the boring tool 305 first, and then moves outward. The boring tool motor 304 rotates to drive the boring tool 305 to rotate, and the pump body shell 4 is bored by the boring tool 305. Every time the half-toothed gear 108 meshes with the shaft gear 110, the slide column 302 moves inward once and resets outward. The slide column 302 and the boring tool 305 arranged on both sides of the main frame 101 can reduce the inclination of the pump body shell 4 during processing, eliminate the opposite force, improve the processing accuracy, and cooperate with the guide column 123 to drive the rotation of the connecting plate 119 to realize the switching of the boring processing on both sides.
