Description

Technical Field

[0001] The invention relates to the technical field of water pump assembly and manufacturing, and in particular to an automatic water pump assembly system. Background Art

[0002] A water pump is a mechanical device used to transport liquid (usually water) from one place to another. It converts the energy of the liquid into kinetic energy or pressure energy through mechanical energy. Common types of water pumps include centrifugal pumps, plunger pumps, and screw pumps. The most critical requirement for a pump body is sealing performance. Mechanical seals are used to prevent liquid leakage inside the pump body. They are usually installed between the pump body and the pump shaft, and ensure sealing performance through a press-fit connection.

[0003] The specific operation is to install the static ring (i.e. the sealing seat part) of the mechanical seal assembly onto the pump casing or stator of the pump body, and assemble the dynamic ring (i.e. the sealing ring part) onto the rotor shaft. In order to accurately and quickly install the static ring into the groove or seat of the pump body, a pressure device is usually used. However, when assembling the static ring of the existing water pump, it is often necessary to manually place the static ring into the corresponding groove, and then crimp it through a pressure device. This process lacks a mechanical mechanism to replace manual labor, and there are certain potential risks. The crimping equipment is not adaptable enough to different models of water pumps, and the system needs to be frequently adjusted or modified. Poor human-machine collaboration will also affect normal production efficiency. Therefore, the present invention proposes an automatic assembly system for water pumps to solve the problems mentioned in the above background technology. Summary of the invention

A ring-mounting cylinder is rotatably connected to the rear part of the upper side of the rotating seat, and the ring-mounting cylinder corresponds to the rear part of the lower longitudinal seat. The lower end of the ring-mounting cylinder is provided with left and right discharge plates;

[0009] A spur gear is fixed at the transfer point of the swivel seat, a tooth plate is arranged on the upper side of the spur gear, a tooth groove meshing with the spur gear is opened at the front of the lower side of the tooth plate, and hydraulic cylinder three is installed on the left and right sides of the outer side of the vertical seat, and the hydraulic cylinder three is connected to the tooth plate.

[0010] Preferably, the two transport mechanisms include a driving device connected to a driving shaft, conveying rollers are installed at both ends of the two conveying frames of the transport mechanism, and corresponding conveying belts are installed outside the two conveying rollers, and a conveying roller in each of the two conveying frames is fixedly installed on the corresponding driving shaft.

[0011] Preferably, the vertical seat slides up and down on the device seat, two studs are fixed on both sides of the vertical seat, and two locking nuts are threadedly connected to the two studs and attached to the side of the device seat.

[0012] Preferably, corresponding circular openings are opened in the centers of the inner sides of the two discharge plates, which are convenient for passing the static ring, a spring is connected between the outer side of the discharge plate and the rotating seat, and an inclined strip is fixed on the outer side of the discharge plate, and the left and right outer sides of the vertical seat are both provided with inclined surfaces corresponding to the inclined strips.

[0013] Preferably, a stud 1 is fixed at the center of the lower side of the longitudinal seat, a slot corresponding to the stud 1 is opened on the lower side of the swivel seat, and a locking nut 1 attached to the lower side of the swivel seat is threadedly connected on the stud 2.

[0014] Preferably, the ring-mounting cylinder is semi-cylindrical, a limiting rotating frame rotatably connected thereto is disposed on the outer side of the ring-mounting cylinder, a limiting protrusion is disposed at the lower end of the limiting rotating frame, and a limiting groove corresponding to the limiting protrusion is opened in the rotating seat.

[0015] Preferably, a push rod 1 and a push rod 2 are provided on the upper side of the transport mechanism, the push rod 1 is perpendicular to the conveying direction of the transport mechanism, and the push rod 2 is parallel to the conveying direction of the transport mechanism, and a clamping frame is fixed to the front end of the push rod 1 and the push rod 2, and a hydraulic cylinder 1 connected to the push rod 1 is installed at the lower part of the device seat, and the water pump on one side of the transport frame is pushed to the device seat through the push rod 1.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1.

Under the advancement of the second hydraulic cylinder, the tooth plate is advanced, and the static ring in the longitudinal seat is advanced forward while controlling the press-fitting mechanism to turn flat. Then, the static ring is accurately positioned and pressed by the first hydraulic cylinder;

[0019] 2. In the process of the rotating seat of the press-fitting mechanism of the present invention being turned flat, due to the relationship between the inclined surface and the corresponding inclined surface, after the rotating seat is completely turned flat, the two connected inner discharge plates also expand outward, so that the static ring inside the ring-fitting cylinder is automatically discharged. With the continuous advancement of the tooth plate, the fallen static ring is pushed forward and transported to the front end through the channel between the left and right clamping plates. After the rotating seat is turned back, the pressure-fitting water pump also loses the clamping fixation between the device seat and the upper side press-fitting mechanism, which makes it convenient for subsequent pushing;

[0020] 3. The ring-mounting cylinder structure designed in the present invention can be conveniently laid flat for assembling the static ring. After being filled, the ring-mounting cylinder is rotated vertically, and the rotating frame is rotated to one side to complete the closure of the ring-mounting cylinder. The outer limit of its lower end is also turned into the limit groove to limit the ring-mounting cylinder from turning flat, and cooperate with the press-fitting mechanism to complete the press-fitting configuration of the static ring of the water pump.

[0021] In summary, the automated pushing and assembly process of this water pump automatic assembly system reduces manual intervention and significantly improves production efficiency. The hydraulic cylinder and mechanical transmission system ensure the precise crimping of the static ring assembly and reduce assembly errors. The design allows the position of each component to be adjusted to meet the needs of different types of water pumps. Automated operation reduces the labor intensity of workers, reduces labor costs, and improves operational safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figure 1-8 , a water pump automatic assembly system, including a transport mechanism 1, the transport mechanism 1 includes two transport frames, a device seat 8 is arranged at the intersection of the two transport frames, a press-fitting mechanism 2 is arranged above the device seat 8, and the press-fitting assembly of the static ring assembly on one side of the water pump is completed on the device seat 8 by the press-fitting mechanism 2. The transport mechanism 1 includes a driving device, and the driving device is connected to a driving shaft 3. Conveying rollers are installed at both ends of the two transport frames of the transport mechanism 1, and corresponding conveying belts are installed outside the two conveying rollers. One conveying roller in the two conveying frames is fixedly installed on the corresponding driving shaft 3;

[0035] Furthermore, referring to Figure 1 , 3, 4. A push rod 1 4 and a push rod 2 5 are arranged on the upper side of the transport mechanism 1. The push rod 1 4 is perpendicular to the transport direction of the transport mechanism 1, and the push rod 2 5 is parallel to the transport direction of the transport mechanism 1, and a clamping frame 6 is fixed to the front end of the push rod 1 4 and the push rod 2 5. A hydraulic cylinder 3 7 connected to the push rod 1 4 is installed at the lower part of the device seat 8. The water pump on one side of the transport frame is pushed to the device seat 8 through the push rod 1 4. After the crimping is completed, the crimped water pump is pushed to the other transport frame on the front side through the push rod 2 5. Racks 10 are connected to the lower sides of the push rod 1 4 and the push rod 2 5. The two racks 10 slide inward and outward in the device seat 8 and the transport mechanism transport frame respectively. An upper and lower bevel gear 9 is arranged on one side of the intersection of the two racks 10. The two bevel gears 9 are fixedly connected and transferred to the device seat The inside of the seat 8, and one side of the two racks 10 are provided with tooth grooves corresponding to the meshing bevel gears 9. The conveying frame on one side of the transport mechanism 1 conveys the water pump assembly and performs intermittent conveying. When the water pump is conveyed to the pushing range of the clamping frame 6 of the push rod 1 4 on one side, the push rod 1 4 pushes the water pump to the surface of the front device seat 8, and due to the transmission of the two bevel gears 9, the clamping frame 6 connected to the push rod 2 5 will retreat. After the press-fitting mechanism 2 completes the press-fitting of a group of water pumps, the hydraulic cylinder 3 7 drives the connected push rod 1 4 to slide outward to release the pressure and fixation of the water pump. At the same time, the push rod 2 5 is driven forward to complete the delivery of the water pump after the press-fitting, so that it is conveyed to the front conveying frame. According to the above process, in cooperation with the press-fitting mechanism 2 on the device seat, the intermittent pushing and assembly of the water pump are completed in sequence;

[0036] Furthermore, referring to Figure 1 , 3 5. The pressing mechanism 2 includes a vertical seat 201, a rotating seat 202 is rotatably connected to the upper side of the vertical seat 201, a longitudinal seat 203 that slides forward and backward is arranged on the upper side of the rotating seat 202, a clamping plate 215 that slides left and right is arranged inside the longitudinal seat 203, the clamping plate 215 is a static ring pushing channel, a spring 213 is arranged between the lower outer side of the clamping plate 215 and the longitudinal seat 203, a round seat 205 is fixed to the front end of the clamping plate 215, and a hydraulic cylinder 204 fixedly installed on the longitudinal seat 203 is arranged above the round seat 205, the bottom surface of the round seat 205 at the front end of the clamping plate 215 is in direct contact with the interface of the water pump, and when assembling the static ring, it is necessary The upper and lower positions of the press-fitting mechanism 2 are adjusted to ensure that the lower side of the round seat 205 is in full contact with the interface surface of the water pump when the rotating seat 202 is in a flat state, thereby ensuring that it can press the pushed water pump and facilitate the press-fitting of the static ring of the water pump. The vertical seat 201 slides up and down on the device seat 8. The left and right sides of the vertical seat 201 are fixed with studs 216, and the studs 216 are threadedly connected with locking nuts 217 attached to the side of the device seat 8. The vertical seat 201 in the device seat 8 is adjusted by sliding up and down, and the adjusted position is instantly locked by the studs 216 on both sides and the corresponding locking nuts 217.

[0037] Furthermore, referring to Figure 7 , a stud 210 is fixed at the center of the lower side of the longitudinal seat 203, a slot corresponding to the stud 210 is provided on the lower side of the swivel seat 202, a locking nut 211 attached to the lower side of the swivel seat 202 is threadedly connected on the stud 216, and a cylindrical block composed of the left and right round seats 205 is provided with a conical groove inside. The static ring is squeezed by the upper hydraulic cylinder 204 so that the static ring passes through the inside of the round seat 205, opens the round seats 205 on both sides, and falls to the sealing part of the water pump interface below. Previously, it was necessary to ensure that the lower side of the round seat 205 completely corresponds to the interface of the water pump. Therefore, after adjusting the up and down position of the round seat 205, it is necessary to adjust its front and rear position, which can be achieved by sliding the longitudinal seat 203 in the swivel seat 202, and by tightening or loosening the locking nut 211 on the stud 210;

[0038] Furthermore, referring to Figure 5 , 6 The upper rear part of the rotating seat 202 is rotatably connected with a ring cylinder 218, and the ring cylinder 218 corresponds to the rear part of the lower longitudinal seat 203. The lower end of the ring cylinder 218 is provided with left and right discharge plates 209, and the inner centers of the two discharge plates 209 are provided with corresponding circular openings. A spring 208 is connected between the outer side of the discharge plate 209 and the rotating seat 202, and an inclined strip 207 is fixed on the outer side of the discharge plate 209, and the left and right outer sides of the vertical seat 201 are provided with inclined surfaces corresponding to the inclined strip 207. When the water pump is pushed onto the assembly seat 8, the rotating seat 202 is turned flat, and the inner longitudinal seat 203 is also turned flat. As it rotates flat, during this process, the outer inclined strip 207 of the discharge plate 209 contacts the corresponding inclined surfaces on the left and right of the vertical seat 201, so that the inner discharge plate 209 connected with the inclined strip 207 is squeezed outward, and the middle spring 1 208 is stretched, and the discharge plate 209 pulled to the left and right, the vertical ring-mounting cylinder 218 above, and the static ring discharge through the corresponding circular mouth and fall on the surface of the corresponding longitudinal seat 203 below. When the rotating seat 202 rotates, the discharge plate 209 connected with the inclined strip 207 on the left and right will return to the initial position under the tension of the spring 1 208;

[0039] Furthermore, referring to Figure 3 , 56. A spur gear 212 is fixed at the transition of the swivel seat 202. A tooth plate 206 is arranged on the upper side of the spur gear 212. A tooth groove meshing with the spur gear 212 is opened at the front of the lower side of the tooth plate 206. Hydraulic cylinders 214 are installed on the left and right sides of the outer side of the vertical seat 201, and the hydraulic cylinders 214 are connected to the tooth plate 206. By controlling the two hydraulic cylinders 214, the front and rear positions of the connected tooth plates 206 can be adjusted. After the tooth groove at the front end of the tooth plate 206 contacts the spur gear 212 at the transition of the swivel seat 202, a transmission occurs, so that the swivel seat 202 rotates flat, and its front end follows the flattened round seat 205 to complete the compression of the water pump interface. At this time, the rear section of the tooth plate 206 no longer meshes with the spur gear 212, but maintains the current rotation angle, and the static ring falling on the longitudinal seat 203 is pushed forward during the continuous advancement of the tooth plate 206, and the static ring is pushed to the middle of the left and right round seats 205 at the front end. When the hydraulic cylinder 1 204 pushes the static ring in the middle of the round seat 205 downward, the clamping plates 215 on both sides are stretched open, and the static ring is continuously pushed into the corresponding interface by the hydraulic cylinder 1 204 to install the static ring on one side of the water pump, and the spring 213 on the outer side of the clamping plate 215 is compressed until the hydraulic cylinder 1 204 retracts, and the clamping plate 215 and the connected round seat 205 are reset;

[0040] Furthermore, referring to Figure 8 The ring-mounting cylinder 218 is semi-cylindrical, and a limiting rotating frame 219 is rotatably connected to the outer side of the ring-mounting cylinder 218, and a limiting protrusion 220 is provided at the lower end of the limiting rotating frame 219, and a limiting groove 221 corresponding to the limiting protrusion 220 is opened in the rotating seat 202. When the ring-mounting cylinder 218 is used to assemble the static ring of the water pump, it cooperates with the pressing mechanism 2 to complete the automatic loading of the static ring. When it is necessary to install the static ring in the ring-mounting cylinder 218, the limiting rotating frame 219 on the ring-mounting cylinder 218 is rotated so that the limiting protrusion 220 rotates out of the corresponding limiting groove 221. At this time, the ring-mounting cylinder 218 can be flattened, and the limiting rotating frame 219 is rotated out of the open position, and the static ring can be installed in the ring-mounting cylinder 218, and then the ring-mounting cylinder 218 filled with static rings is turned vertically, and the limiting rotating frame 219 on one side is rotated to close one side of the ring-mounting cylinder 218 and limit the flat rotation of the ring-mounting cylinder 218.
