Description

Technical Field

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

[0002] The horizontal multi-stage stainless steel pump is a multi-stage centrifugal pump whose flow-through parts are made of stainless steel. It has the advantages of high efficiency and energy saving, low noise, corrosion resistance and compact structure. During the production process of its stainless steel pump head, two circular through holes will be opened on the side wall as the water inlet and outlet. Both circular through holes need to be welded with internal threaded pipes to facilitate the connection of external pipelines.

[0003] In order to avoid stains remaining on the surface of the stainless steel pump head or the internal threaded tube and affecting the welding quality, workers are usually required to wipe and clean the joint between the stainless steel pump head and the internal threaded tube before welding. In addition, since the two circular through holes on the stainless steel pump head are respectively located on the top and side surfaces of the stainless steel pump head, and the welding gun of the welding equipment can usually only move within the set track, it is necessary to change workstations during the cleaning and welding process to use different brackets to support the stainless steel pump head and use another welding gun for welding, which further reduces the processing efficiency.

[0004] Therefore, it is necessary to design a horizontal multi-stage stainless steel pump processing equipment that can automatically clean the joint between the stainless steel pump head and the internal threaded pipe without changing the work station to improve the cleaning and welding efficiency, in order to address the defect of existing equipment that requires changing the work station to use different brackets and welding guns when welding the internal threaded pipe on the top and side surfaces of the stainless steel pump head.

[0015] The beneficial effects of the present invention are: 1. The device can drive the rotating shaft to rotate by controlling the motor, and then drive the transmission shaft to rotate through the belt transmission part.

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

[0017] 3. After the rotating support rod rotates 90 degrees around the rotating bent rod, the pump head rotates 90 degrees accordingly, and the circular through hole on the corresponding side after the pump head rotates is coaxial with the circular through hole before the pump head rotates, but at different heights. The adaptive adjustment component can be used to clean and weld internal threaded pipes and pump heads of different heights without adjusting the position of the fixture, cleaning pad and welding gun, which greatly improves the processing efficiency.

[0018] 4. When cleaning the joint between the pump head and the internal threaded pipe, first bend the pressure rod to press the arc-shaped pressure block against the outside of the cleaning pad so that the cleaning pad can fit completely with the joint between the pump head and the internal threaded pipe to ensure the cleaning effect.

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

[0020] 6. During the transportation of the internal threaded tube, the lifting material stopper can be moved to the bottom of the storage barrel to prevent the internal threaded tube in the storage barrel from falling freely. In the process of placing the internal threaded tube, under the action of the discharge spring, the lifting material stopper and the electromagnetic clamp can stop descending in time when they come into contact with the pump head, so as to realize the function of transporting the internal threaded tube to different heights.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1: A horizontal multi-stage stainless steel pump processing equipment, such as Figures 1-12As shown, 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 109, a return spring 110, a welding connecting rod 207, a tightening block 2071, a welding gun 208, a rotating disk 4, a bevel gear 401, a rotating pressing mechanism and a rotating support mechanism. The top of the fixed frame 1 is fixedly connected to the top bracket 101, the control motor 102 is installed in the fixed frame 1, and the fixed frame 1 is rotatably connected to the rotating support mechanism. The output shaft of the control motor 102 is fixedly connected to the rotating shaft 103, and the top bracket 101 is rotatably connected with a transmission shaft 105. The transmission shaft 105 and the rotating shaft 103 are connected through a belt transmission member 104. The top bracket 101 is symmetrically slidably connected with a lifting slide 109. The lifting slide 109 and the top bracket 101 are connected through a return spring 110. One end of the return spring 110 is fixed on the lifting slide 109, and the other end is fixed on the lifting slide The cam 208 is connected to the upper and lower frames 101, and the lower and upper frames 102 are connected to the upper and lower frames 103.

[0036] During the processing, it is necessary to weld the internal threaded pipe to 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 pump head is supported by a rotating support mechanism, and then the internal threaded pipe is placed on the circular through hole on the pump head. The rotating support mechanism provides support for the internal threaded pipe. Before welding, the rotating motor 102 is controlled to drive the rotating shaft 103 to rotate, and 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 bar 109 to descend through the rotating pressing mechanism. The rotating pressing mechanism cleans the joint between the internal threaded pipe and the pump head. When the rotating pressing mechanism drops to the lowest point, the joint between the pump head and the internal threaded pipe will be cleaned first. After cleaning, the motor 102 is controlled to rotate the rotating shaft 10 3 drives the rotating disk 4 and the bevel gear 401 to rotate in the opposite direction and reset, and then drives the transmission shaft 105 and the rotary pressing mechanism to rise and reset through the belt transmission part 104. After the lifting slide bar 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 to the bottom of the welding gun 208 through the bevel gear 401. As the control motor 102 continues to rotate, the rotary pressing mechanism drives the welding connecting rod 207 and the welding gun 208 to descend through the lifting slide bar 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, and then the welding gun 208 is controlled to rotate around the internal threaded pipe and weld the internal threaded pipe to the outside of the pump casing.

[0037] Example 2: Based on Example 1, Figure 1-Figure 7 As shown, the rotating downward 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 in the top bracket 101, and the swing rod 107 is rotatably connected in 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, and 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 of different heights.

[0038] When cleaning the surface of the pump head, the control motor 102 drives the rotating shaft 103 to rotate counterclockwise, and the rotating shaft 103 drives the transmission shaft 105 to rotate counterclockwise through the belt transmission member 104. The transmission shaft 105 rotates counterclockwise to drive the rotating push rod 106 to rotate counterclockwise, and 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 lifting slide bar 109 on the left to slide downward along the top bracket 101 through the connecting shaft 108. During the descent of the lifting slide bar 109 on the left, the reset spring 110 is compressed. When the lifting slide bar 109 on the left descends, it descends through the adaptive adjustment component and the cleaning component. The adaptive adjustment component belt During the descent of the dynamic cleaning component, the cleaning component first contacts the pump head, and 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 tube at the circular through holes on the pump head. When the lifting slide bar 109 drops to the lowest point, the cleaning component cleans the connection between the pump head and the internal threaded tube. After cleaning, the control motor 102 drives the rotating shaft 103 to rotate clockwise and reset, and the belt drive 104 and the transmission shaft 105 rotate clockwise and reset accordingly, and the rotating push rod 106 rotates accordingly and returns to a horizontal state, and the swing rod 107 and the connecting shaft 108 return to their original positions.

[0039] like Figure 2 and Figure 3 As 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 spline shaft 2 is fixedly connected to the bottom of the lifting slide rod 109, and the sliding sleeve rod 201 is slidingly connected inside the spline shaft 2. The bottom of one sliding sleeve rod 201 is fixed to the connecting seat 203, and the other sliding sleeve rod 201 is connected to the welding connecting rod 207. The spline shaft 2 and the corresponding connecting seat 203 or the welding connecting rod 207 are connected through the buffer spring 202. The buffer spring 202 is sleeved on the outside of the sliding sleeve rod 201. One end of the buffer spring 202 is fixed to the spline shaft 2, and the other end is fixed to the corresponding connecting seat 203 or the welding connecting rod 207.

[0040] like Figure 3 、 Figure 4 and Figure 6As shown, the cleaning assembly includes a sliding seat 204, a cleaning pad 205, a pressing spring 206, a cleaning motor 305, a driving gear 306, a transmission gear 307 and a seam pressing assembly. The sliding seat 204 is slidably connected to the connecting seat 203, and a cleaning pad 205 is installed in the sliding seat 204. The sliding seat 204 and the connecting seat 203 are connected through a pressing spring 206. One end of the pressing spring 206 is fixed to the sliding seat 204, and the other end is fixed to the connecting seat 203. A cleaning motor 305 is installed on the top of the fixing frame 1, and the fixing frame 1 The top is rotatably connected with a driving gear 306 and a transmission gear 307, and 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, and the cleaning motor 305 drives the transmission gear 307 to rotate through the driving gear 306. A spline groove is provided in the transmission gear 307, and the spline shaft 2 can be inserted into the spline groove in the transmission gear 307 during the descending process. The pressing seam assembly is installed outside the sliding seat 204, and the pressure sealing assembly is used to press the cleaning pad 205 tightly at the joint between the internal threaded tube and the pump head.

[0041] like Figure 4 and Figure 5 As shown, the pressing seam assembly includes a bent pressure rod 3, a fixed rod 301, a fixed slide 302, a return spring 303 and an arc-shaped pressure block 304. The bent pressure rod 3 is symmetrically fixed to the outside of the connecting seat 203, and the fixed rod 301 and the fixed slide 302 are fixed to the outside of the sliding seat 204. The fixed rod 301 is located at the top of the fixed slide 302, and the fixed rod 301 and the fixed slide 302 are jointly slidably connected with the arc-shaped pressure block 304. The inner wall of the arc-shaped pressure block 304 matches the outer wall of the cleaning pad 205, and the arc-shaped pressure block 304 can be attached to the outside of the cleaning pad 205. The arc-shaped pressure block 304 and the fixed rod 301 are connected by the return spring 303. One end of the return spring 303 is fixed to the fixed rod 301, and the other end is fixed to the arc-shaped pressure block 304.

[0042] When the lifting slide bar 109 descends, the spline shaft 2 is pushed down, and the sliding sleeve rod 201, the buffer spring 202 and the connecting seat 203 are lowered accordingly. The cleaning pad 205 will be sleeved outside the internal threaded tube to clean the through hole at the high position of the pump head. When the bottom surface of the cleaning pad 205 is in contact with the top of the pump head, the lifting connecting rod continues to descend and continues to descend through the spline shaft 2. During the descending process 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 to descend through the buffer spring 202. During the descending process of the connecting seat 203, the compression spring 206 is compressed. At the same time, the bending pressure rod 3 is lowered. During the descending process of the bending pressure rod 3, the arc pressure block 304 is pushed to slide along the fixed rod 301 and the fixed slide 302 to the outer corner close to the cleaning pad 205. The return spring 303 is compressed at the same time. When the lifting slide bar 109 descends to When the cleaning pad 205 is rotated, the arc pressing block 304 cleans the joint between the internal threaded pipe and the pump head through the cleaning pad 205. After cleaning, the control motor 102 drives the transmission shaft 105 to rotate and reset through the rotating shaft 103 and the belt transmission member 104, and the rotating 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] like Figures 8-10 As 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 in the fixed frame 1, and the rotating bent rod 402 is coaxially fixed with 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 a frustum, and a section of the end of the frustum-shaped structure at the top of the rotating support rod 404 can tighten the internal threaded pipe to be welded from the inside, and the tightening assembly is installed on the rotating support rod 404.

[0044] like Figures 8-10As shown, the tightening assembly includes a wedge-shaped support block 403, a sliding support pad 405, a connecting spring 406 and an arc-shaped support plate 407. The wedge-shaped support block 403 is fixed on the rotating bent rod 402, and the 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 through the 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 rotation of the rotating support rod 404 around the rotating bent rod 402, the wedge-shaped support block 403 can support the sliding support pad 405 upward, and the arc-shaped support plate 407 is fixed on the rotating bent rod 402. The arc-shaped support plate 407 is used to provide support for the rotating support rod 404 after rotation.

[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 on the top of the pump head to provide support for the pump head. When the internal threaded tube is placed at the circular through hole on the top of the pump head, the frustum-shaped structure on the top of the mobile support rod just supports the internal threaded tube from the bottom. After the internal threaded tube is placed at the circular hole on the top of the pump head and cleaned, the rotating support rod 404 is manually pushed 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 tube. After the pump head rotates 90 degrees, the circular through hole on its side wall The hole is facing upwards, and the height of the circular through hole on the side wall of the pump head is lowered. Under the action of the adaptive adjustment component, the cleaning component and the welding gun 208 can weld the internal threaded tubes of different heights and the circular through holes on the pump head. In this process, the frustum-shaped structure at the end of the rotating support rod 404 will support the internal threaded tube to prevent it from sliding outwards. At this time, the arc-shaped support plate 407 provides support for the rotating support rod 404. During the rotation of the rotating support rod 404, the sliding support pad 405 rotates accordingly. 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, the internal threaded tube is placed on 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 tube from the inside. During the cleaning and welding process, the rotating support rod 404 and the sliding support pad 405 can provide support for the internal threaded tube, which can prevent the internal threaded tube from rotating during the cleaning and welding process to ensure the cleaning and welding effect. The internal threaded tube is placed on the pump head and cleaned. After completion, the control motor 102 drives 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 device thereon will drive the pump head and the internal threaded tube to rotate toward the bottom of the welding gun 208. When the pump head and the internal threaded tube rotate to the bottom of the welding gun 208, there is still a certain distance between the clamping block at the bottom of the welding connecting rod 207 and the internal threaded tube to avoid contact with the welding gun 208 during the rotation and displacement of the pump head and the internal threaded tube. The same is true for the process of the pump head and the internal threaded tube moving to the bottom of the cleaning pad 205.

[0046] like Figure 11 and Figure 12 As shown, it also includes a feeding mechanism for pushing the internal threaded tube, which includes a storage barrel 5, a pushing cylinder 501, a sliding guide frame 502, a sliding guide frame 503, a compression spring 504, an arc-shaped blocking rod 505 and a delivery assembly. The fixed frame 1 is equipped with a storage barrel 5, which is used to store the internal threaded tube to be welded. The height between the bottom outlet of the storage barrel 5 and the fixed frame 1 is just the same as the height of the internal threaded tube to be welded. The fixed frame 1 is equipped with a pushing cylinder 501, and the fixed frame 1 is slidably connected to the sliding guide frame 502. The pushing cylinder 501 The telescopic rod is fixedly connected to the sliding guide frame 502, and a sliding guide frame 503 is slidably connected inside the sliding guide frame 502. The sliding guide frame 503 and the sliding guide frame 502 are connected by a compression spring 504. One end of the compression spring 504 is fixed on the sliding guide frame 503, and the other end is fixed on the sliding guide frame 502. The two sliding guide frames 503 are connected by an arc-shaped baffle rod 505. The delivery assembly is installed in the sliding guide frame 503 and the sliding guide frame 502. The delivery assembly is used to clamp the internal threaded pipe and place the internal threaded pipe in the circular through hole on the steel pump casing.

[0047] like Figure 12 As shown, the delivery assembly includes a connecting slider 506, a lifting stop frame 507, a discharge spring 508 and an electromagnetic clamp 509. The connecting slider 506 is slidably connected in the sliding guide frame 503, and the lifting stop frame 507 is slidably connected in the sliding guide frame 502. The lifting stop frame 507 and the connecting slider 506 are connected through the discharge spring 508. One end of the discharge spring 508 is fixed on the lifting stop frame 507, and the other end is fixed on the connecting slider 506. The lifting stop frame 507 is fixed with an electromagnetic clamp 509. The electromagnetic clamp 509 is used to clamp the internal threaded pipe and place it in the circular through hole on the steel pump casing.

[0048] When the pump head is placed on the rotating support rod 404, the pushing cylinder 501 is started, and the pushing cylinder 501 controls the sliding guide frame 502 and the device thereon to slide along the fixed frame 1 in the direction close to the storage barrel 5. When the electromagnetic clamping block 509 contacts the internal threaded tube that falls on the fixed frame 1, the electromagnetic clamping block 509 is energized and clamps the internal threaded tube. As the sliding guide frame 502 continues to move, the lifting and lowering material blocking frame 507 will cover the outlet at the bottom of the storage barrel 5 to prevent the internal threaded tube from falling from the storage barrel 5. When the electromagnetic clamping block 509 drives the internal threaded tube When it moves to the top of the pump head and aligns with the circular through hole on the pump head, the arc-shaped blocking rod 505 just contacts the storage barrel 5, pushing the cylinder 501 to push the sliding guide frame 502 to continue moving. At this time, since the sliding guide frame 503 is restricted and cannot move, the connecting slider 506 in the sliding guide frame 503 is also restricted and cannot move. As the sliding guide frame 502 continues to move, the connecting slider 506 will slide down along the sliding guide frame 503 under the push of the inclined guide groove on the sliding guide frame 502, raising and lowering the blocking frame 507 and the discharge spring 508. The electromagnetic clamp 509 then descends. During the process of the electromagnetic clamp 509 descending, the internal threaded tube is placed in the circular through hole on the pump head. When the electromagnetic clamp 509 contacts the pump head, the sliding guide frame 502 continues to move, and the connecting slider 506 is pushed down and compresses the discharge 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 discharge spring 508, the electromagnetic clamp 509 can place the internal threaded tube at different heights. After the internal threaded tube is placed, the electromagnetic clamp 509 is powered off and released. In addition to clamping the internal threaded tube, the cylinder 501 is pushed at this time to drive the sliding guide frame 502 to slide and reset, and the connecting slider 506, the lifting stop frame 507, the discharge spring 508 and the electromagnetic clamp 509 rise and reset first. When the connecting slider 506 rises to the highest point, as the sliding guide frame 502 continues to move, the sliding guide frame 503, the compression spring 504 and the arc-shaped baffle rod 505 move and reset accordingly, and under the action of the discharge spring 508, the electromagnetic clamp 509 can place the internal threaded tube at the circular through holes at different heights on the pump head.
