Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, specifically to a polishing device for a circulating water pump accessory. Background Technology

[0002] Circulating water pumps are installed at heating stations, heat sources, or cold sources. Within the closed loop of a heating or air conditioning water system, the circulating water pump does not lift the water to a higher level, but rather circulates the water continuously within the system to overcome the resistance loss of the loop. During the production process of circulating water pumps, specialized equipment is required for polishing.

[0003] Existing circulating water pump accessories lack a real-time waste collection mechanism during polishing. Because the open polishing area easily leads to waste splashing and scattering into the work area, polluting the workshop environment, workers need to stop the machine for cleaning, thus reducing the overall processing efficiency of the device. To address this issue, we provide a circulating water pump accessory polishing device to solve the above problems. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a waste chip collection mechanism, the timely, rapid, and centralized collection and cleaning of polishing waste chips can be achieved. It can not only collect waste chips during polishing to prevent them from flying and scattering, but also move with the polishing chamber to ensure that the waste chips are completely collected and then completely dumped out. When the collection box is close to the placement slot, the waste chips can be collected by the collection box. When the collection box is pushed out, it will tilt and the waste chips can be dumped out. The movement of the collection box does not require manual adjustment. It responds quickly and is highly efficient, and the application is also safer.

[0016] 2. By setting up a polishing chamber, the polishing area is enclosed, preventing waste chips from flying out and facilitating their collection. An air supply system is installed in the polishing chamber, which not only cools the workpiece but also creates a swirling airflow within the chamber. This blows away the accumulated waste chips, allowing them to pass more effectively through the chip collection plate and preventing excessive chip buildup that could cause blockages.

[0017] 3. By setting up a waste chip auxiliary discharge mechanism, the problem of waste chip clogging on the chip collection concave plate is further prevented. After the extension rod rotates, it will swing the hammer shot with the help of the nylon belt. The hammer shot rubs against the chip collection concave plate and generates vibration, which can clear the waste chip blocking the chip collection concave plate, so that the waste chip can quickly pass through the chip collection concave plate and be collected.

[0018] 4. By setting up a workpiece clamping mechanism, the workpiece can be stably clamped while being moved automatically and quickly without manual adjustment. The position of the workpiece can be moved and the placement angle of the workpiece can be adjusted accordingly, so that different surfaces of the workpiece can be polished flexibly. It is not only suitable for polishing irregular workpieces, but also greatly improves polishing efficiency, making the polishing work faster and more accurate. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-11 This embodiment provides a polishing device for circulating water pump accessories, including: The platform includes a water platform base 1 and a shifting groove 2 located in the middle of the upper part of the water platform base 1. A polishing machine mounting bracket 6 is fixedly connected to the upper right end of the water platform base 1. A lifting rod 7 is installed in the middle of the upper part of the polishing machine mounting bracket 6. A supporting plate 8 is connected to the top of the lifting rod 7. A polishing motor 9 is fixedly installed on the inner side of the supporting plate 8. A polishing disc 10 is connected to the bottom output end of the polishing motor 9. A sliding platform 11 is slidably installed on the inner side of the shifting groove 2. Sliding mechanisms for moving the sliding platform 11 are provided on both the front and rear sides of the sliding platform 11. A waste chip collection mechanism for collecting and dumping waste chips is provided below the sliding platform 11. A polishing chamber 29 is fixedly connected to the upper part of the sliding platform 11. A waste chip auxiliary discharge mechanism for preventing waste chip blockage is provided on the lower inner side of the polishing chamber 29. A workpiece clamping mechanism for clamping workpieces is provided on the upper inner side of the polishing chamber 29. The waste chip collection mechanism includes a placement mechanism located in the middle of the lower surface of the sliding platform 11. The groove 14 has a horizontal sliding groove 20 in the middle of both sides of the groove wall. The inner side of the sliding groove 20 is slidably installed with a moving block 21. The right side of the moving block 21 is connected to a first hydraulic telescopic rod 22. The input end of the first hydraulic telescopic rod 22 is installed with a first hydraulic cylinder 23. The left end of both sides of the groove wall 14 is rotatably connected with a rotating plate 24. The outer wall of the rotating plate 24 is fixedly connected with a pull rod 25. The end of the pull rod 25 is connected to a connecting rod 26 through a shaft. The two ends of the connecting rod 26 away from the sliding groove 20 are fixed with connecting rods 27. The end of the connecting rod 27 is connected to a storage box 28. The bottom left side of the inner cavity of the storage box 28 is set as an inclined surface. The waste chip collection mechanism also includes a waste chip output groove 15 that runs vertically through the middle of the sliding platform 11. A chip collection concave plate 16 is fixedly connected above the waste chip output groove 15. The inside of the chip collection concave plate 16 is uniformly perforated with through holes 17. A polishing machine, namely a polishing motor 9 and a polishing disc 10, is installed on the water platform base 1 using a polishing machine mounting bracket 6. The polishing head required for processing is installed on the polishing disc 10. The polishing motor 9 is balanced and supported by the support plate 8, and can move up and down under the lifting action of the lifting rod 7. Thus, the polishing disc 10 moves up and down accordingly, so that the cutting and lifting actions can be flexibly completed, and the polishing work can be carried out smoothly. Below the sliding platform 11, a storage box 28 is assembled via a placement slot 14 for hoisting. The front and rear side walls of the storage box 28 are connected to a set of pull rod assemblies, namely a pull rod 25 and a connecting rod 26, via connecting rods 27. The connecting rod 26 is directly connected to the storage box 28 via the connecting rod 27, and its position is fixed to the storage box 28, moving with it. The pull rod 25 is rotatably connected to the connecting rod 26, and the pull rod 25 is also rotatably connected to the sliding platform 11 via a rotating piece 24. Therefore, the pull rod 25 can rotate relative to the connecting rod 26. A hydraulic telescopic control component is connected to the right side of the moving block 21. Utilizing the hydraulic telescopic control principle of the first hydraulic cylinder 23 on the first hydraulic telescopic rod 22, the moving block 21 can slide back and forth in the moving slide 20. The moving block 21 is directly connected to the right end of the connecting rod 26. Therefore, during the movement of the moving block 21, the connecting rod 26 will tilt accordingly, and the angle between the pull rod 25 and the connecting rod 26 will change accordingly. Specifically… When the moving block 21 moves to the left, the angle between the pull-down rod 25 and the connecting rod 26 decreases; when the moving block 21 moves to the right, the angle between the pull-down rod 25 and the connecting rod 26 increases. As the angle between the pull-down rod 25 and the connecting rod 26 increases, the storage box 28 gradually rises until its top is in contact with the top surface of the placement slot 14. This allows it to collect the waste debris that leaks from the polishing chamber 29, and the waste debris can be completely collected in the storage box 28. When the angle between the pull-down rod 25 and the connecting rod 26 decreases, the left side of the storage box 28 gradually tilts downward, allowing the waste debris inside the storage box 28 to be poured out. This is very convenient and quick. The entire process does not require manual operation. In addition to being quick and convenient, the storage box 28 directly follows the polishing chamber 29, which not only collects and cleans the waste debris generated during the polishing process in a timely manner, but also concentrates the waste debris while polishing, preventing it from scattering everywhere. The waste debris in the storage box 28 is cleaned out by pouring it out, which is very quick and convenient.

[0023] Example 2: The sliding mechanism includes limiting slide grooves 3 respectively disposed on the inner walls of the front and rear sides of the displacement groove 2. Baffles 4 are fixedly connected to the front and rear sides of the left end of the displacement groove 2. Lead screws 5 are installed on the front and rear sides of the inner side of the displacement groove 2, and the left ends of the lead screws 5 are respectively rotatably engaged in the right side of the baffles 4. The sliding mechanism also includes sliding blocks 12 respectively fixed on the front and rear sides of the sliding platform 11. The interior of each sliding block 12 is penetrated by a connecting circular groove 13, and the lead screws 5 pass through the interior of the connecting circular groove 13 respectively. The sliding platform 11 moves within the shifting groove 2 by means of the lead screw 5. The sliding platform 11 moves smoothly. When the sliding platform 11 moves under the polishing machine mounting frame 6, polishing can be performed. When the sliding platform 11 moves away from under the polishing machine mounting frame 6 and returns to its initial position, the workpiece can be disassembled or the waste collected in the storage box 28 can be emptied and cleaned.

[0024] Example 3: The polishing chamber 29 has a conical cylindrical structure, and the interior of the polishing chamber 29 has a spiral airflow channel. The lower part of the outer wall of the polishing chamber 29 is fixedly connected to the outlet pipe 30 which is connected to the airflow channel. The inner wall of the polishing chamber 29 has air inlets 31 that are connected to the airflow channel. The air inlets 31 are evenly distributed on the inner wall of the polishing chamber 29 in a spiral pattern at equal intervals, and the orientation of the air inlets 31 is horizontal. The conical cylindrical structure of the polishing chamber 29 is designed to enclose the polishing area, allowing polishing to take place inside the chamber. This prevents the waste chips generated during polishing from scattering and facilitates their collection. In addition, the polishing chamber 29 is equipped with an air supply system. A spiral airflow channel is set inside the chamber wall of the polishing chamber 29, with its bottom end connected to the outlet pipe 30 and connected to the inner cavity of the polishing chamber 29 through multiple air inlets 31. Air enters from the outlet pipe 30 and is blown into the polishing chamber 29 through each air inlet 31. This not only provides air cooling for the workpiece but also creates a swirling airflow within the polishing chamber 29 due to the spiral arrangement of the air inlets 31. This better disperses the accumulated waste chips within the polishing chamber 29, allowing them to pass smoothly through the through holes 17 on the chip collection concave plate 16, preventing excessive waste chips from causing blockages.

[0025] Example 4: The waste chip auxiliary discharge mechanism includes a central seat 18 fixedly disposed at the center of the upper surface of the chip collecting concave plate 16. A rotary motor 19 is assembled below the central seat 18, and the output end of the rotary motor 19 passes through the center of the central seat 18 and is connected to a hollow rotating shaft 32. A gear ring 33 is fixed at the top of the hollow rotating shaft 32, and a connecting ring 34 is meshed with the outer teeth of the gear ring 33. An extension rod 35 is fixedly connected to the outer wall of the connecting ring 34 at equal angles, and a nylon belt 36 is connected to the lower end of each extension rod 35. A hammer 37 is connected to the bottom end of each nylon belt 36. The length of each extension rod 35 increases clockwise with the central axis of the connecting ring 34 as the center. In order to avoid the problem of waste chips clogging the through holes 17, an auxiliary waste chip discharge mechanism is additionally provided in the polishing chamber 29. The rotation control motor 19 controls the rotation of the hollow rotating shaft 32, and under the meshing connection between the outer wall saw teeth of the gear ring 33 and the inner wall saw teeth of the connecting ring 34, the connecting ring 34 rotates together with the hollow rotating shaft 32, so that each extending rod 35 rotates accordingly, and through each nylon belt 36, the hammering ball 37 is swung under the action of centrifugal force. The hammering ball 37 is in contact with the chip collecting concave plate 16, and after being swung, it will generate relative friction with the chip collecting concave plate 16 and cause vibration, whereby the clogged waste chips on the chip collecting concave plate 16 can be dredged, so that the waste chips can quickly pass through the chip collecting concave plate 16 and be collected. The lengths of the extending rods 35 are different but change regularly, increasing one by one, so that the entire area of the chip collecting concave plate 16 can be covered, leaving no cleaning dead angle on the chip collecting concave plate 16, and waste chips cannot accumulate on the chip collecting concave plate 16.

[0026] Example 5: The workpiece clamping mechanism includes a second hydraulic cylinder 38 movably assembled inside the hollow rotating shaft 32, the output end of the second hydraulic cylinder 38 is connected with a second hydraulic telescopic rod 39, and the end of the second hydraulic telescopic rod 39 is connected with a polishing seat 40 that is hollow inside and has a hemispherical shape. A "米"-shaped movable groove 41 is opened on the upper shell wall of the polishing seat 40, the movable groove 41 is divided into a supporting groove surface 42 and a stepped tooth surface 43, the supporting groove surface 42 and the stepped tooth surface 43 are sequentially connected, and a supporting groove 44 is provided in the middle of the surface of the supporting groove surface 42. A compensating center column 45 is vertically fixed at the center of the polishing seat 40, and stepped teeth 46 are fixedly provided on both the outer wall of the circular truncated cone at the top end of the compensating center column 45 and the surface of the stepped tooth surface 43. The workpiece clamping mechanism further includes a supporting sliding seat 47 fixedly connected to the bottom of the compensating center column 45, spherical grooves 48 are annularly provided on the upper inclined surface of the supporting sliding seat 47, a spherical head 49 is slidably installed inside the spherical groove 48, an adapter rod 50 is fixedly connected to the outer wall of the spherical head 49 exposed out of the spherical groove 48, an elastic telescopic rod 51 with a spring arranged inside is fixedly connected to the end of the adapter rod 50, a motor mounting plate 52 is fixedly connected to the end of the elastic telescopic rod 51, a rotating motor 53 is installed on the side of the motor mounting plate 52 away from the elastic telescopic rod 51, a gear post 54 is connected to the output shaft end of the rotating motor 53, the gear post 54 is meshed with the stepped teeth 46, the gear post 54 is slidably assembled in the supporting groove 44, a positioning plate 55 is connected to the upper shaft end of the gear post 54, clamping plates inclined upward at an angle of 30° are fixedly provided at equal distances on the upper edge of the positioning plate 55, and clamping hooks are provided at the ends of the clamping plates; Under the hydraulic telescopic control of the second hydraulic cylinder 38 on the second hydraulic telescopic rod 39, the polishing seat 40 can be quickly lifted and lowered. When the polishing seat 40 is raised, the workpiece can be lifted out of the polishing chamber 29, which facilitates the disassembly and assembly of the workpiece. During polishing, the polishing seat 40 is lowered, which can ensure that waste chips are concentrated in the polishing chamber 29 without spilling out. The cross-shaped (rice-shaped) movable groove 41 provided on the polishing seat 40 not only enables the positioning plate 55 to move along the upper circular surface of the polishing seat 40 to adjust its inclination angle, thereby adjusting the placement angle of the workpiece, so that different surfaces of the workpiece can be polished without secondary clamping of the workpiece, but also enables the positioning plate 55 to move in multiple directions along the cross-shaped (rice-shaped) trajectory, so that the workpiece can be adjusted in multiple directions with a large range of angle changes, and polishing processing is more flexible and efficient. The stepped tooth surface 43 section of the movable groove 41 is provided with stepped teeth 46 meshed with the gear column 54. After the rotating motor 53 is started, it will drive the gear column 54 to rotate. Under the action of the inter-tooth meshing structure, the gear column 54 will rotate and move along the distribution direction of the stepped teeth 46. A supporting groove 44 for the sliding of the gear column 54 is provided on the supporting groove surface 42 section, and the gear column 54 can rotate and move along the direction of the supporting groove 44. After the gear column 54 moves, the motor mounting plate 52 connected to the rotating motor 53 moves accordingly, and drives the connected elastic telescopic rod 51 to move. A spring is arranged inside the elastic telescopic rod 51, so its length can elastically expand and contract. The bottom end of the elastic telescopic rod 51 is connected with a spherical head 49 through a connecting rod 50. The spherical head 49 is fitted and installed in a spherical groove 48, and can rotate its angle along the spherical groove 48, so that the elastic telescopic rod 51 can change its own length and inclination angle following the movement of the gear column 54, thereby ensuring a stable supporting effect on the rotating motor 53 and realizing the smooth movement of the gear column 54 in the movable groove 41. The positioning plate 55 can automatically move and change angles on the upper circular surface of the polishing seat 40, so that the workpiece can be stably moved to the desired position without manual adjustment, which saves time and greatly improves the polishing processing efficiency. The clamping plates 56 uniformly fixed obliquely upward on the positioning plate 55 are used for clamping the workpiece. The clamping plates 56 wrap the bottom of the workpiece through the clamping hooks 57 at their top ends. The inclined arrangement of the clamping plates 56 also enables the clamping plates 56 to have certain structural elasticity. After the workpiece is placed inside the clamping plates 56, the reset elasticity of the clamping plates 56 can help clamp the workpiece and hold it firmly.
