Description

Technical Field

[0001] The present invention relates to the technical field of pump body processing, and particularly relates to a processing device for a horizontal multi-stage stainless steel pump. Background Art

[0002] A horizontal multi-stage stainless steel pump is a multi-stage centrifugal pump, and its flow-through components are made of stainless steel material, having the advantages of high efficiency and energy saving, low noise, corrosion resistance, compact structure, etc. During the production of its stainless steel pump head, two circular through-holes are opened on the side wall as the water inlet and outlet, and internal threaded pipes need to be welded at both circular through-holes for connecting external pipelines.

[0003] In order to avoid stains remaining on the surface of the stainless steel pump head or the internal threaded pipe, which may affect the welding quality, workers usually need to wipe and clean the joint between the stainless steel pump head and the internal threaded pipe before welding. And since the two circular through-holes on the stainless steel pump head are respectively located on the top surface and the side surface of the stainless steel pump head, and the welding torch of the welding equipment can usually only move within a set trajectory, it is necessary to switch workstations during the cleaning and welding processes to support the stainless steel pump head with different brackets and use another welding torch for welding, resulting in a further reduction in processing efficiency.

[0004] Therefore, it is necessary to design a processing device for a horizontal multi-stage stainless steel pump, aiming at the defect that the existing equipment needs to switch workstations to use different brackets and welding torches when welding the internal threaded pipes on the top surface and the side surface of the stainless steel pump head, which can automatically clean the joint between the stainless steel pump head and the internal threaded pipe and does not need to switch workstations to improve the cleaning and welding efficiency.

[0015] The beneficial effects of the present invention are as follows: 1.

[0016] 2. The device drives the rotating bent rod and the pump head to rotate through the rotating disk and the bevel gear.

[0017] 3. After the rotating support rod rotates 90 degrees around the rotating bent rod, the pump head rotates 90 degrees accordingly. After the pump head rotates, the circular through holes on the corresponding side are coaxial but not at the same height as those before the pump head rotates. Through the adaptive adjustment component, the internal threaded pipe and the pump head at different heights can be cleaned and welded without adjusting the positions of the fixture, the cleaning pad, and the welding torch, greatly improving the processing efficiency.

[0018] 4. When cleaning the joint between the pump head and the internal threaded pipe, first press the arc-shaped pressing block tightly outside the cleaning pad through the bent pressing rod, so that the cleaning pad can be completely attached to the joint between the pump head and the internal threaded pipe to ensure the cleaning effect.

[0019] 5. During the cleaning and welding process, the rotating support rod and the sliding support pad tighten the internal threaded pipe from the inside to prevent the internal threaded pipe from rotating under force, so as to ensure the processing effect.

[0020] 6. During the process of conveying the internal threaded pipe, the lifting material blocking frame can move to the bottom of the storage barrel to prevent the internal threaded pipes in the storage barrel from falling freely. And during the process of placing the internal threaded pipe, under the action of the feeding spring, the lifting material blocking frame and the electromagnetic clamping block can stop descending in time when contacting the pump head, so as to realize the function of conveying the internal threaded pipe to different heights.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1: A processing device for a horizontal multi-stage stainless steel pump, as Figures 1 - 12As shown in the figure, it includes a fixed frame 1, a top bracket 101, a control motor 102, a rotating shaft 103, a belt transmission member 104, a transmission shaft 105, a lifting slide rod 109, a return spring 110, a welding connecting rod 207, a tightening block 2071, a welding torch 208, a rotating disk 4, a bevel gear 401, a rotating and pressing mechanism, and a rotating support mechanism. The top of the fixed frame 1 is fixedly connected with the top bracket 101. The control motor 102 is installed inside the fixed frame 1. The rotating shaft 103 is rotatably connected inside the fixed frame 1. The output shaft of the control motor 102 is fixedly connected with the rotating shaft 103. The transmission shaft 105 is rotatably connected inside the top bracket 101. The transmission shaft 105 and the rotating shaft 103 are connected by the belt transmission member 104. The lifting slide rods 109 are symmetrically and slidably connected inside the top bracket 101. The lifting slide rods 109 and the top bracket 101 are connected by the return spring 110. One end of the return spring 110 is fixed on the lifting slide rod 109, and the other end is also fixed on the lifting slide rod 109. The rotating disk 4 is fixedly connected to the rotating shaft 103. The bevel gear 401 is rotatably connected inside the fixed frame 1. Teeth are fixed at one end of the rotating disk 4 close to the bevel gear 401. The teeth on the rotating disk 4 are meshed with the bevel gear 401. The rotating and pressing mechanism is installed on the top bracket 101. One side of the lifting slide rod 109 is provided with the welding connecting rod 207 through the rotating and pressing mechanism. The bottom of the welding connecting rod 207 is fixedly connected with the tightening block 2071. The tightening block 2071 presses tightly inside the internal thread tube. The welding torch 208 is installed on the welding connecting rod 207. Under the action of the welding torch 208, the internal thread tube and the pump head are welded together with a welding rod. During the welding process, the tightening block 2071 can press the internal thread tube tightly to prevent the position of the internal thread tube from shifting during the welding process. The rotating and pressing mechanism can drive the welding connecting rod 207 and the welding torch 208 to descend through the lifting slide rod 109. The rotating support mechanism is installed inside the fixed frame 1. The rotating support mechanism is used to support the internal thread tube and drive it to rotate.

[0036] During the processing, the internal threaded pipe needs to be welded at the circular through hole on the pump head of the stainless steel pump to form a water inlet and a water outlet on the pump head of the stainless steel pump. Before welding, the support mechanism is rotated to support the pump head. Subsequently, the internal threaded pipe is placed at the circular through hole on the pump head, and the support mechanism is rotated to support the internal threaded pipe. Before welding, the control motor 102 is driven to drive the rotating shaft 103 to rotate. The rotating shaft 103 drives the transmission shaft 105 to rotate through the belt transmission member 104. The transmission shaft 105 drives the lifting slide rod 109 to descend through the rotating and pressing mechanism. The rotating and pressing mechanism cleans the joint between the internal threaded pipe and the pump head. When the rotating and pressing mechanism descends to the lowest position, it will first clean the joint between the pump head and the internal threaded pipe. After the cleaning is completed, the control motor 102 drives the rotating disk 4 and the bevel gear 401 to rotate in the reverse direction and reset through the rotating shaft 103. Furthermore, the transmission shaft 105 and the rotating and pressing mechanism are driven to rise and reset through the belt transmission member 104. After the lifting slide rod 109 rises and resets under the drive of the reset spring 110, the control motor 102 continues to rotate and drives the rotating disk 4 to continue to rotate through the rotating shaft 103. The rotating disk 4 drives the rotating support mechanism to rotate under the drive of the bevel gear 401 to below the welding torch 208. As the control motor 102 continues to rotate, the rotating and pressing mechanism drives the welding connecting rod 207 and the welding torch 208 to descend through the lifting slide rod 109. When the tightening block 2071 contacts the top of the internal threaded pipe, the tightening block 2071 can provide support for the internal threaded pipe from the inside. Subsequently, the welding torch 208 is controlled to rotate around the internal threaded pipe and the internal threaded pipe is welded outside the pump shell.

[0037] Embodiment 2: On the basis of Embodiment 1, as Figures 1 - 7 shown, the rotating and pressing mechanism includes a rotating push rod 106, a swing rod 107, a connecting shaft 108, an adaptive adjustment component, and a cleaning component. The rotating push rod 106 is rotatably connected inside the top bracket 101. The swing rod 107 is rotatably connected inside the top bracket 101. The connecting shaft 108 is slidably connected to the swing rod 107. The connecting shaft 108 is fixedly connected to the lifting slide rod 109. The adaptive adjustment component is installed on the lifting slide rod 109. The cleaning component is installed in the adaptive adjustment component. Under the action of the adaptive adjustment component, the cleaning component can clean the internal threaded pipes at different heights.

[0038] When cleaning the surface of the pump head, control the motor 102 to drive the rotating shaft 103 to rotate counterclockwise. The rotating shaft 103 drives the transmission shaft 105 to rotate counterclockwise through the belt transmission part 104. The counterclockwise rotation of the transmission shaft 105 drives the rotating push rod 106 to rotate counterclockwise. The rotating push rod 106 pushes the swing rod 107 at the left end to swing downward. When the swing rod 107 at the left end swings downward, it drives the left lifting slide rod 109 to slide downward along the top bracket 101 through the connecting shaft 108. During the process of the left lifting slide rod 109 descending, the return spring 110 is compressed. When the left lifting slide rod 109 descends, it descends through the adaptive adjustment component and the cleaning component. During the process of the adaptive adjustment component driving the cleaning component to descend, the cleaning component first contacts the pump head. Since there are two circular through holes on the pump head and the heights of the two circular through holes on the pump head are different, under the action of the adaptive adjustment component, the cleaning component can always contact the internal threaded pipe at the circular through hole on the pump head. When the lifting slide rod 109 descends to the lowest position, the cleaning component cleans the connection between the pump head and the internal threaded pipe. After cleaning, control the motor 102 to drive the rotating shaft 103 to rotate clockwise to reset. The belt transmission part 104 and the transmission shaft 105 rotate clockwise to reset accordingly. The rotating push rod 106 rotates and returns to the horizontal state. The swing rod 107 and the connecting shaft 108 return to their original positions.

[0039] As Figure 2 and Figure 3 shown, the adaptive adjustment component includes a spline shaft 2, a sliding sleeve rod 201, a buffer spring 202, and a connecting seat 203. The bottom of the lifting slide rod 109 is fixedly connected with the spline shaft 2. The sliding sleeve rod 201 is slidably connected inside the spline shaft 2. The bottom of one sliding sleeve rod 201 is fixedly connected with the connecting seat 203. The other sliding sleeve rod 201 is connected with the welding connecting rod 207. The spline shaft 2 is connected with the corresponding connecting seat 203 or the welding connecting rod 207 through the buffer spring 202. The buffer spring 202 is sleeved outside the sliding sleeve rod 201. One end of the buffer spring 202 is fixed on the spline shaft 2, and the other end is fixed on the corresponding connecting seat 203 or the welding connecting rod 207.

[0040] As Figure 3 、 Figure 4 and Figure 6As shown, the cleaning component includes a sliding seat 204, a cleaning pad 205, a compression spring 206, a cleaning motor 305, a driving gear 306, a transmission gear 307 and a seam pressing component. A sliding seat 204 is slidably connected within a connecting seat 203. A cleaning pad 205 is installed within the sliding seat 204. The sliding seat 204 and the connecting seat 203 are connected by a compression spring 206. One end of the compression spring 206 is fixed on the sliding seat 204, and the other end is fixed on the connecting seat 203. A cleaning motor 305 is installed on the top of the fixing frame 1. A driving gear 306 and a transmission gear 307 are rotatably connected to the top of the fixing frame 1. The driving gear 306 and the transmission gear 307 are meshed. The output shaft of the cleaning motor 305 is fixedly connected to the driving gear 306. The cleaning motor 305 drives the transmission gear 307 to rotate through the driving gear 306. A spline groove is formed within the transmission gear 307. During the downward movement of the spline shaft 2, it can be inserted into the spline groove within the transmission gear 307. The seam pressing component is installed outside the sliding seat 204. The seam pressing component is used to press the cleaning pad 205 tightly against the joint between the internal thread pipe and the pump head.

[0041] As Figure 4 and Figure 5 shown, the seam pressing component includes a bent pressing rod 3, a fixing rod 301, a fixing slideway 302, a return spring 303 and an arc-shaped pressing block 304. Bent pressing rods 3 are symmetrically and fixedly connected outside the connecting seat 203. A fixing rod 301 and a fixing slideway 302 are fixedly connected outside the sliding seat 204. The fixing rod 301 is located at the top of the fixing slideway 302. An arc-shaped pressing block 304 is slidably connected within the fixing rod 301 and the fixing slideway 302. The inner wall of the arc-shaped pressing block 304 matches the outer wall of the cleaning pad 205. The arc-shaped pressing block 304 can be attached to the outside of the cleaning pad 205. The arc-shaped pressing block 304 and the fixing rod 301 are connected by a return spring 303. One end of the return spring 303 is fixed on the fixing rod 301, and the other end is fixed on the arc-shaped pressing block 304.

[0042] During the downward movement of the lifting slide rod 109, the spline shaft 2 is pushed downward, and the sliding sleeve rod 201, the buffer spring 202, and the connecting seat 203 also move downward accordingly. The cleaning pad 205 will cover the outer thread tube. When cleaning the through hole at a high position of the pump head, when the bottom surface of the cleaning pad 205 fits against the top of the pump head, the lifting connecting rod continues to move downward and the spline shaft 2 continues to move downward. During the downward movement of the spline shaft 2, the sliding sleeve rod 201 slides into the spline shaft 2, and the buffer spring 202 between the spline shaft 2 and the connecting seat 203 is compressed. The spline shaft 2 pushes the connecting seat 203 to continue moving downward through the buffer spring 202. During the downward movement of the connecting seat 203, the compression spring 206 is compressed, and at the same time, it moves downward through the bent pressure rod 3. During the downward movement of the bent pressure rod 3, it will push the arc-shaped pressing block 304 to slide along the fixed rod 301 and the fixed slideway 302 towards the outer corner of the cleaning pad 205, and the return spring 303 is compressed at the same time. When the lifting slide rod 109 descends to the lowest position, the arc-shaped pressing block 304 is just pressed against the outer corner of the cleaning pad 205. At this time, the spline shaft 2 just inserts into the spline groove on the transmission gear 307. Start the cleaning motor 305, and the cleaning motor 305 drives the transmission gear 307 to rotate through the driving gear 306. When the transmission gear 307 rotates, it drives the sliding sleeve rod 201 and the connecting seat 203 to rotate through the spline shaft 2. The connecting seat 203 drives the cleaning pad 205 to rotate through the sliding seat 204. During the rotation of the cleaning pad 205, the arc-shaped pressing block 304 cleans the joint between the inner thread tube and the pump head through the cleaning pad 205. After cleaning, control the motor 102 to drive the transmission shaft 105 to rotate and reset through the rotating shaft 103 and the belt transmission member 104, and the rotation and pressing mechanism moves and resets as a whole; when manufacturing this equipment, technicians can install a hot air dryer on the equipment to dry the reset cleaning pad 205 and blow off the impurities on its surface.

[0043] As Figures 8 - 10 shown, the rotating support mechanism includes a rotating bent rod 402, a rotating support rod 404, and a tightening assembly. The rotating bent rod 402 is rotatably connected inside the fixed frame 1. The rotating bent rod 402 is coaxially fixed to the bevel gear 401. The rotating support rod 404 is rotatably connected to the rotating bent rod 402. The top of the rotating support rod 404 is frustum-shaped, and a section at the end of the frustum-shaped structure at the top of the rotating support rod 404 can tightly support the inner thread tube to be welded from the inside. The tightening assembly is installed on the rotating support rod 404.

[0044] As Figures 8 - 10As shown, the tightening component includes a wedge-shaped support block 403, a sliding support pad 405, a connecting spring 406, and an arc-shaped support plate 407. A wedge-shaped support block 403 is fixedly connected to the rotating bent rod 402. A sliding support pad 405 is slidably connected to the rotating support rod 404. The sliding support pad 405 and the rotating support rod 404 are connected by a connecting spring 406. One end of the connecting spring 406 is fixed on the sliding support pad 405, and the other end is fixed on the rotating support rod 404. During the process of the rotating support rod 404 rotating around the rotating bent rod 402, the wedge-shaped support block 403 can push the sliding support pad 405 upward. An arc-shaped support plate 407 is fixedly connected to the rotating bent rod 402, and the arc-shaped support plate 407 is used to support the rotated rotating support rod 404.

[0045] When the pump head is placed outside the rotating bent rod 402, the top of the rotating support rod 404 is aligned with the circular through hole at the top of the pump head to support the pump head. When the internal threaded pipe is placed at the circular through hole at the top of the pump head, the conical structure at the top of the moving support rod just supports the internal threaded pipe from the bottom. When the internal threaded pipe is placed at the circular hole at the top of the pump head and the cleaning is completed, manually push the rotating support rod 404 to rotate downward around the rotating bent rod 402. The rotating support rod 404 drives the pump head to rotate 90 degrees through the internal threaded pipe. After the pump head rotates 90 degrees, the circular through hole on its side wall faces upward, and at this time, the height of the circular through hole on the side wall of the pump head decreases. Under the action of the adaptive adjustment component, both the cleaning component and the welding torch 208 can weld the circular through holes on the internal threaded pipe and the pump head at different heights. During this process, the conical structure at the end of the rotating support rod 404 will support the internal threaded pipe to prevent the internal threaded pipe from sliding outwards. At this time, the arc-shaped support plate 407 supports the rotating support rod 404. During the rotation of the rotating support rod 404, the sliding support pad 405 rotates accordingly. During the rotation of the sliding support pad 405, under the support of the wedge-shaped support block 403, the sliding support pad 405 slides upward along the rotating support rod 404, and the connecting spring 406 is stretched. After the rotation is completed, place the internal threaded pipe at the circular through hole on the side of the pump head. At this time, the sliding support pad 405 provides support for the internal threaded pipe from the inside. During the cleaning and welding process, both the rotating support rod 404 and the sliding support pad 405 can provide support for the internal threaded pipe, and the internal threaded pipe can be prevented from rotating during the cleaning and welding process to ensure the cleaning and welding effects. After the internal threaded pipe is placed on the pump head and the cleaning is completed, control the motor 102 to drive the rotating disk 4 to rotate clockwise through the rotating shaft 103. Driven by the bevel gear 401, the rotating bent rod 402 and the devices thereon will drive the pump head and the internal threaded pipe to rotate towards the bottom of the welding torch 208. When the pump head and the internal threaded pipe rotate to the bottom of the welding torch 208, there is still a certain distance between the pressing block at the bottom of the welding connecting rod 207 and the internal threaded pipe to prevent the pump head and the internal threaded pipe from contacting the welding torch 208 during the process of rotating and shifting. The same is true for the process of the pump head and the internal threaded pipe moving towards the bottom of the cleaning pad 205.

[0046] As Figure 11 and Figure 12 shown, it further includes a feeding mechanism for pushing the internal-thread pipe. The feeding mechanism includes a storage cylinder 5, a pushing cylinder 501, a sliding guide frame 502, a sliding guide box 503, a compression spring 504, an arc-shaped stop rod 505 and a feeding component. The storage cylinder 5 is installed in the fixed frame 1. The storage cylinder 5 is used to store the internal-thread pipes to be welded. The height between the bottom outlet of the storage cylinder 5 and the fixed frame 1 is exactly the same as the height of the internal-thread pipes to be welded. The pushing cylinder 501 is installed in the fixed frame 1. The sliding guide frame 502 is slidably connected in the fixed frame 1. The telescopic rod of the pushing cylinder 501 is fixedly connected to the sliding guide frame 502. The sliding guide box 503 is slidably connected in the sliding guide frame 502. The sliding guide box 503 and the sliding guide frame 502 are connected by the compression spring 504. One end of the compression spring 504 is fixed on the sliding guide box 503, and the other end is fixed on the sliding guide frame 502. The two sliding guide boxes 503 are connected by the arc-shaped stop rod 505. The feeding component is installed in the sliding guide box 503 and the sliding guide frame 502. The feeding component is used to clamp the internal-thread pipe and place the internal-thread pipe at the circular through-hole on the steel pump housing.

[0047] As Figure 12 shown, the feeding component includes a connecting slider 506, a lifting material stop frame 507, a discharging spring 508 and an electromagnetic clamp 509. The connecting slider 506 is slidably connected in the sliding guide box 503. The lifting material stop frame 507 is slidably connected in the sliding guide frame 502. The lifting material stop frame 507 and the connecting slider 506 are connected by the discharging spring 508. One end of the discharging spring 508 is fixed on the lifting material stop frame 507, and the other end is fixed on the connecting slider 506. The electromagnetic clamp 509 is fixedly connected to the lifting material stop frame 507. The electromagnetic clamp 509 is used to clamp the internal-thread pipe and place it at the circular through-hole on the steel pump housing.

[0048] After the pump head is placed on the rotating support rod 404, the pushing cylinder 501 is started. The pushing cylinder 501 controls the sliding guide frame 502 and the devices thereon to slide along the fixed frame 1 towards the direction close to the storage cylinder 5. When the electromagnetic clamping block 509 contacts the internal threaded pipe that has fallen on the fixed frame 1, the electromagnetic clamping block 509 is energized and clamps the internal threaded pipe. As the sliding guide frame 502 continues to move, the lifting and blocking frame 507 will cover the outlet at the bottom of the storage cylinder 5 to prevent the internal threaded pipe from falling out of the storage cylinder 5. When the electromagnetic clamping block 509 drives the internal threaded pipe to move to the top of the pump head and aligns with the circular through-hole opened on the pump head, the arc-shaped blocking rod 505 just contacts the storage cylinder 5. The pushing cylinder 501 pushes the sliding guide frame 502 to continue moving. At this time, since the sliding guide frame 503 is restricted from moving, the connecting slider 506 in the sliding guide frame 503 is also restricted from moving. As the sliding guide frame 502 continues to move, under the push of the inclined guide groove on the sliding guide frame 502, the connecting slider 506 will slide downward along the sliding guide frame 503, and the lifting and blocking frame 507, the discharging spring 508 and the electromagnetic clamping block 509 will descend accordingly. During the descending process of the electromagnetic clamping block 509, the internal threaded pipe is placed in the circular through-hole on the pump head. When the electromagnetic clamping block 509 contacts the pump head, the sliding guide frame 502 continues to move, and the connecting slider 506 is pushed to descend and compress the discharging spring 508. Since the height of the circular through-hole on the side of the pump head is lower after the pump head rotates 90 degrees, under the action of the discharging spring 508, the electromagnetic clamping block 509 can place the internal threaded pipe at different height positions. After the internal threaded pipe is placed, the electromagnetic clamping block 509 is powered off and releases the clamping of the internal threaded pipe. At this time, the pushing cylinder 501 drives the sliding guide frame 502 to slide back to the original position. The connecting slider 506, the lifting and blocking frame 507, the discharging spring 508 and the electromagnetic clamping block 509 first rise back to the original position. When the connecting slider 506 rises to the highest position, as the sliding guide frame 502 continues to move, the sliding guide frame 503, the compression spring 504 and the arc-shaped blocking rod 505 move back to the original position accordingly. And under the action of the discharging spring 508, the electromagnetic clamping block 509 can place the internal threaded pipe at the circular through-holes at different heights on the pump head.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present invention.
