Description

Technical Field

[0001] This invention relates to the technical field of impeller processing equipment, and in particular to a polishing machine for impeller processing and its usage method. Background Technology

[0002] The impeller is the only component in bladed fluid machinery that transfers energy to the fluid. It converts the mechanical energy of the prime mover into the kinetic and pressure energy of the fluid. The impeller has a complex structure, consisting of several curved blades. The blades are non-developable twisted ruled surfaces, which presents certain difficulties in traditional precision machining.

[0003] During production, liquid ball milling technology is used to polish the surface of the impeller. The impeller is inserted into a liquid containing ball milling particles and rotated, so that the particles rub against the surface of the impeller continuously, achieving the polishing effect.

[0004] However, in order to improve polishing efficiency, existing polishing equipment often polishes multiple sets of impellers continuously. Since a certain amount of particles are generated after the impellers are polished and mixed into the liquid, the impellers polished later experience greater particle resistance in the liquid, resulting in a greater degree of polishing. This affects the polishing degree of different batches of impellers, and in particular, it can easily cause greater wear on the surface of the impellers polished later, which is quite inconvenient. Summary of the Invention

[0029] An eccentric wheel is fixedly inserted and connected to the transmission rod.

One end of the second compression spring is fixedly connected to the screening box, and the other end of the second compression spring is fixedly connected to the inner wall of the machine body.

[0035] Preferably, the adjustment mechanism includes:

[0049] Preferably, a pump body is fixedly installed on one side of the machine body, and the pump body can pump the polishing liquid filtered by the filter screen back to the impeller polishing position.

[0050] The present invention also provides a method of using a polishing machine for impeller processing, including the following specific steps:

[0051] Step 1: Rotate the bidirectional screw to bring multiple clamping blocks closer together and clamp the impeller at the bottom of the sealing plate. At this time, start the cylinder so that the sealing plate can drive the impeller to make the sealing plate stick to the top of the machine body and form a sealed polishing cavity with the bearing plate. The sealing plate can also be connected to the rotating rod.

[0052] Step 2: Start the motor. The motor drives the rotating rod to rotate through the transmission rod, which in turn drives the clamped impeller to rotate and polish the impeller with the polishing liquid and steel balls inside the polishing chamber.

[0053] Step 3: After polishing, a large number of impurities are mixed in the polishing liquid. At this time, the winding rod can be rotated. The rotation of the winding rod can drive the threaded rod to rotate through multiple helical gears. By adjusting the position of the sliding block, the guide plate can be adjusted vertically and the connecting ring can be lifted to open the sealing plug. This allows the polishing liquid mixed with impurities to flow into the screening box. At the same time, the pump is started to re-inject the polishing liquid into the polishing chamber to stabilize the polishing operation.

[0054] Step 4: While the winding rod rotates, the pull rope can be unwound, thereby releasing the pull on the reciprocating plate. Under the elastic force of the second compression spring, the reciprocating plate can be pressed tightly against the eccentric wheel. Thus, while the transmission rod rotates and drives the rotating rod to rotate the impeller for polishing, the eccentric wheel can be driven to filter the polishing liquid containing impurities flowing down.

[0055] The technical effects and advantages of this invention are as follows:

[0056] (1) The present invention utilizes a combination of sealing mechanism, transmission mechanism, steel ball, filtration mechanism and adjustment mechanism. The transmission mechanism can drive the impeller held by the clamping mechanism to rotate, thereby cooperating with polishing liquid and steel ball to perform liquid ball milling operation on the impeller. When the polishing liquid contains a lot of impurities, the sealing plug can be opened by the adjustment mechanism to allow the polishing liquid to flow downward and be filtered by the filtration mechanism, and then pumped back by the pump body to form a cycle. This ensures the polishing quality of multiple impellers, reduces the impact of impurities on subsequent polishing, and is easy to use.

[0057] (2) The present invention utilizes a combination of a guide plate, an extrusion rod, a moving component, and an adjusting component. By rotating the winding rod in the moving component, the guide plate can slide within the inner cavity of the machine body, and the extrusion rod can squeeze the connecting ring, thereby opening the sealing plug and allowing the polishing liquid containing impurities to flow down. At the same time, the rotation of the winding rod can cancel the pulling of the connecting rope, so that the reciprocating plate can be tightly attached to the eccentric wheel. Thus, the polishing liquid flowing down can be filtered while polishing. When the sealing plug is not opened, the winding rod can be used to wind up the rope, so that the reciprocating plate is in the extreme position and the eccentric wheel cannot contact the reciprocating plate. Thus, when the sealing plug cannot be opened and the polishing liquid does not need to be filtered, the load of the motor driving the filtration mechanism to sieve can be eliminated, thereby extending the service life of the motor. At the same time, the pump body does not need to work, reducing energy consumption. Attached Figure Description

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.

[0067] This invention provides, for example Figure 1-7 The polishing machine for impeller processing shown includes a machine body 1, with a mounting frame 2 fixedly connected to its top. The mounting frame 2 has a C-shaped cross section and a clamping mechanism 3 for fixing the impeller is provided on the mounting frame 2.

[0068] Furthermore, the machine body 1 is equipped with a circulating polishing device, which includes: a sealing mechanism 4, a transmission mechanism 5, steel balls 6, a filtering mechanism 7, and an adjusting mechanism 8. The sealing mechanism 4 is located inside the machine body 1 and, together with the clamping mechanism 3, forms a sealed cavity for sealing the polishing liquid. The transmission mechanism 5 is located inside the machine body 1 and is used to drive the impeller to rotate. Multiple steel balls 6 are located at the top of the sealing mechanism 4 and can work with the polishing liquid to polish the rotating impeller. The filtering mechanism 7 is located at the bottom of the transmission mechanism 5 and can drive the filtering mechanism 7 to perform a filtering operation. The adjusting mechanism 8 is located inside the machine body 1 and is used to open and close the sealing mechanism 4 and the filtering mechanism 7.

[0069] The clamping mechanism 3 includes: a cylinder 31, a fixed plate 32, a sealing plate 33, a bidirectional screw 34, and a clamping block 35. The cylinder 31 is fixedly mounted on the top of the mounting frame 2. The output end of the cylinder 31 is connected to the fixed plate 32 via a transmission connection. The cylinder 31 is connected to a drive source via an external switch. By starting the switch, the cylinder 31 can be controlled to move the fixed plate 32 vertically. Multiple limit rods are fixedly connected to the top of the fixed plate 32. These limit rods are slidably inserted into the mounting frame 2, further stabilizing the vertical movement of the fixed plate 32. The sealing plate 33 is rotatably mounted on the fixed plate 2. Multiple rotating blocks are fixedly connected to the bottom end of the fixed plate 32 and the top end of the sealing plate 33. An annular groove is provided at the bottom end of the fixed plate 32, and the sealing plate 33 can rotate at the bottom end of the fixed plate 32 through the rotating blocks. A groove is provided at the bottom end of the sealing plate 33, and the two ends of the bidirectional screw 34 extend in the left and right direction and are rotatably disposed inside the groove. Multiple clamping blocks 35 are threadedly connected to the bidirectional screw 34. The cross-section of the clamping block 35 is L-shaped. By rotating the bidirectional screw 34, the multiple clamping blocks 35 can be driven to move closer to each other, thereby fixing and clamping the impeller in the middle, which is convenient for subsequent rotation and polishing operations.

[0070] Furthermore, the sealing mechanism 4 includes: a support plate 41, a sealing plug 42, sliding rods 43, a connecting ring 44, and a first compression spring 45. The support plate 41 is fixedly connected to the inside of the machine body 1. Multiple steel balls 6 are disposed at the top of the support plate 41. The support plate 41 can isolate a cavity at the top of the machine body 1 for grinding the impeller. Multiple through slots are equidistantly opened at the top of the support plate 41. The sealing plug 42 is slidably inserted into the inner cavity of the through slots, and the sealing plug 42 can block the through slots, thereby ensuring that the polishing liquid does not flow down during polishing. Multiple sliding rods 43 are equidistantly fixedly connected to the bottom end of the sealing plug 42. Multiple sliding rods 43 are slidably inserted into the support plate 41. The spacing of the multiple sliding rods 43 is smaller than the diameter of the steel balls 6, thereby... When opened, only polishing liquid and impurities flow downwards, while the steel balls 6 used for grinding remain inside the grinding cavity formed by the top of the support plate 41. The connecting ring 44 is fixedly connected to the bottom end of multiple slide rods 43, and the connecting ring 44 is used to control the vertical movement of the multiple slide rods 43. Multiple first compression springs 45 are spaced apart and sleeved on the outside of the multiple slide rods 43. One end of the first compression spring 45 is fixedly connected to the support plate 41, and the other end of the first compression spring 45 is fixedly connected to the connecting ring 44. The first compression spring 45 is always in a compressed state, so that it can always provide a stable downward elastic force to the connecting ring 44, thereby pulling the sealing plug 42 through the slide rod 43 to ensure sealing.

[0071] Furthermore, the transmission mechanism 5 includes: a motor 51, a transmission rod 52, a rotating rod 53, and an eccentric wheel 54. The motor 51 is fixedly installed inside the machine body 1 and is electrically connected to an external power supply through an external switch. The output end of the motor 51 is connected to the transmission rod 52. The rotating rod 53 is fixedly connected to the top end of the transmission rod 52 and is rotatably inserted into the bearing plate 41. The bottom end of the sealing plate 33 has a rotating groove, and the rotating rod 53 cooperates with the inner cavity of the rotating groove. The cross-section of the rotating rod 53 is square, so that after the cylinder 31 drives the sealing plate 33 to move down, it can be inserted into the rotating rod 53, thereby driving the motor 51 to drive the impeller clamped on the entire sealing plate 33 to rotate. With the help of polishing liquid and steel balls 6, liquid ball milling can be performed to achieve polishing. The eccentric wheel 54 is fixedly inserted into the transmission rod 52 and cooperates with the filter mechanism 7.

[0072] Furthermore, the filtration mechanism 7 includes: a sieving box 71, reciprocating rods 72, a filter screen 73, and second compression springs 74. The sieving box 71 is disposed inside the machine body 1. Multiple reciprocating rods 72 are respectively fixedly connected to both sides of the sieving box 71, and the reciprocating rods 72 are slidably inserted into the inner wall of the machine body 1. The filter screen 73 is fixedly installed at the bottom of the sieving box 71 to block impurities inside the polishing liquid. Multiple second compression springs 74 are respectively fixedly connected to the outside of multiple reciprocating rods 72 on one adjacent side. One end of the second compression spring 74 is fixedly connected to the sieving box 71, and the other end of the second compression spring 74 is fixedly connected to the inner wall of the machine body 1. The second compression spring 74 is always in a compressed state, thereby providing a stable elastic force to the sieving box 71, so that the sieving box 71 can always be in a position slightly to the left inside the machine body 1 without the action of external force.

[0073] Furthermore, the adjustment mechanism 8 includes: a guide plate 81, a squeezing rod 82, a moving component 83, and a pulling component 84. The guide plate 81 is slidably connected to the inner cavity of the machine body 1. The top of the guide plate 81 is provided with an inclined surface, so that the sealing plug 42 is opened, and the polishing liquid can flow accurately into the interior of the screening box 71 along the inclined surface. Multiple squeezing rods 82 are fixedly connected to the top of the guide plate 81 at equal intervals. The squeezing rods 82 are used to push up the connecting ring 44 when the guide plate 81 moves upward, thereby opening the sealing plug 42. The squeezing rods 82 and the connecting ring 44 cooperate with each other. The moving component 83 is disposed inside the machine body 1. The moving component 83 can drive the guide plate 81 to move vertically and open the sealing plate 33 through the squeezing rod 82 to perform a filtration operation on the polishing liquid. The pulling component 84 is connected to the moving component 83 and can limit the state of the screening box 71.

[0074] Furthermore, the moving component 83 includes: a take-up rod 831, a threaded rod 832, a helical gear 833, a sliding rod 834, and a slider 835. The take-up rod 831 is rotatably connected to the machine body 1. Grooves are provided on both sides of the inner wall of the machine body 1. The two ends of the threaded rod 832 are rotatably connected to the inner wall of one of the grooves. One end of the take-up rod 831 and the threaded rod 832 are respectively fixedly connected to multiple helical gears 833, and the multiple helical gears 833 are meshed together. The two ends of the sliding rod 834 are fixedly connected to the inner wall of another groove. The guide plate 81 is slidably connected to the inner cavity of the machine body 1 through the slider 835. One slider 835 is threadedly connected to the threaded rod 832, and the other slider 835 is slidably connected to the sliding rod 834. The rotation of the take-up rod 831 can drive the threaded rod 832 to rotate through the multiple helical gears 833, thereby adjusting the position of the slider 835 to achieve vertical adjustment of the guide plate 81.

[0075] Furthermore, the pulling assembly 84 includes a reciprocating plate 841 and a pull rope 842. The reciprocating plate 841 is fixedly connected to the top of the screening box 71 and cooperates with the eccentric wheel 54. One end of the pull rope 842 is fixedly connected to the reciprocating plate 841, and the other end of the pull rope 842 is fixedly connected to the winding rod 831. When the winding rod 831 rotates and the guide plate 81 rises, the winding of the pull rope 842 can be canceled, thereby canceling the pulling of the reciprocating plate 841. Under the elastic force of the second compression spring 74, the reciprocating plate 841 can be tightly pressed against the eccentric wheel 54, thereby canceling the pulling of the transmission rod. The rotation of the rotating rod 53 causes the impeller to rotate and polish, while simultaneously driving the eccentric wheel 54 to filter the impurity-containing polishing liquid flowing down. When filtration is not required, the winding rod 831 can be rotated in the opposite direction to wind up the pull rope 842, thereby placing the reciprocating plate 841 at its limit position. The eccentric wheel 54 cannot contact the reciprocating plate 841, thus eliminating the load of the motor 51 driving the filtration mechanism 7 to sieve when the sealing plug 42 cannot be opened and filtration of polishing liquid is not required. This extends the service life of the motor 51, and the pump body 9 does not need to work, reducing energy consumption.

[0076] Furthermore, a pump body 9 is fixedly installed on one side of the machine body 1. The pump body 9 can pump the polishing liquid filtered by the filter screen 73 back to the impeller grinding position. The pump body 9 is electrically connected to an external power supply through an external switch, so that the filtered polishing liquid can be pumped back to the impeller grinding position to form a cycle, thereby further reducing costs.

[0077] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.

The guide plate (81) is slidably connected to the inner cavity of the body (1) through the slider (835).

7. A polishing machine for impeller processing according to claim 6, characterized in that, The pulling assembly (84) includes: A reciprocating plate (841) is fixedly connected to the top of the screening box (71), and the reciprocating plate (841) cooperates with the eccentric wheel (54). A pull rope (842) is fixedly connected at one end to a reciprocating plate (841) and at the other end to a winding rod (831).

8. A polishing machine for impeller processing according to claim 7, characterized in that, A pump body (9) is fixedly installed on one side of the machine body (1). The pump body (9) can pump the polishing liquid filtered by the filter screen (73) back to the impeller polishing position.

9. The method of using a polishing machine for impeller processing according to claim 8, characterized in that, The specific usage steps are as follows: Step 1: Rotate the bidirectional screw (34) to bring multiple clamping blocks (35) closer together and clamp the impeller at the bottom of the sealing plate (33). At this time, start the cylinder (31) so that the sealing plate (33) can drive the impeller so that the sealing plate (33) is attached to the top of the machine body (1) and forms a sealed polishing cavity with the bearing plate (41). The sealing plate (33) can be inserted and connected with the rotating rod (53). Step 2: Start the motor (51). The motor (51) drives the rotating rod (53) to rotate through the transmission rod (52), thereby driving the clamped impeller to rotate and polishing with the polishing liquid and steel balls (6) inside the polishing chamber. Step 3: After polishing, a large number of impurities are mixed in the polishing liquid. At this time, the winding rod (831) can be rotated. The rotation of the winding rod (831) can drive the threaded rod (832) to rotate through multiple helical gears (833). Thus, by adjusting the position of the sliding block (835), the guide plate (81) can be adjusted vertically, and the connecting ring (44) can be lifted, thereby opening the sealing plug (42) so that the polishing liquid mixed with impurities can flow into the interior of the screening box (71). At the same time, the pump body (9) is started to re-inject the polishing liquid into the interior of the polishing cavity to stabilize the polishing operation. Step 4: While the winding rod (831) is rotating, the pull rope (842) can be unwound, thereby releasing the pull on the reciprocating plate (841). Under the elastic force of the second compression spring (74), the reciprocating plate (841) can be pressed tightly against the eccentric wheel (54). Thus, while the transmission rod (52) rotates and drives the rotating rod (53) to make the impeller rotate for polishing, the eccentric wheel (54) can be driven to filter the polishing liquid containing impurities flowing down.
