Description

Technical Field

[0001] This invention relates to the field of guide cone grinding technology, specifically to a fan guide cone grinding device with curved surface adaptability. Background Technology

[0002] A fan guide cone is a device used to guide fluid, typically used in fan or blower systems. Its main function is to change the direction and speed of the fluid to optimize the performance and efficiency of the fan. Usually, the surface of a fan guide cone is very rough after production, so it needs to be polished to reduce the impact of surface roughness on fluid flow.

[0003] In the existing technology, the grinding of the guide cone of the fan is usually done by workers manually. The manual grinding method is not only labor-intensive, time-consuming and laborious, but also inefficient. It is difficult to ensure the integrity and consistency of the surface quality of the workpiece. At the same time, the noise and dust at the work site also seriously affect the health of the workers. Summary of the Invention

[0004] The purpose of this invention is to provide a grinding device for a fan guide cone with curved surface adaptability, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A fan guide cone grinding device with curved surface adaptation includes: a body, on one side of which a sliding door is symmetrically arranged and slidably connected to the body; a grinding table is arranged inside the body and rotatably connected to the body; a grinding device is also arranged inside the body and slidably connected to the body; the grinding device includes: a movable disc and slidably connected to the body.

[0008] The worker places the blower guide cone to be ground on the grinding table surface. The clamping plate on the grinding table then secures the guide cone. After the guide cone is secured, the worker closes the sliding door, creating a sealed space in the grinding chamber. The controller then starts the motor, and the drive shaft in the motor rotates the grinding table. As the grinding table rotates, it drives the guide cone to rotate. Simultaneously, the controller activates the hydraulic cylinder, and the hydraulic rod in the cylinder moves the moving disc closer to the grinding chamber. During the movement of the moving disc, the controller activates the grinding device, which then grinds the guide cone. Because the surface of the guide cone is curved, the grinding device adaptively adjusts its grinding radius according to the curvature of the guide cone during grinding, thus achieving curved surface grinding, saving grinding time and improving grinding efficiency.

[0009] Preferably, the machine body is provided with a grinding chamber, the movable disk is provided with a moving chamber, the movable disk is provided with a plurality of moving grooves on the side near the grinding table, the plurality of moving grooves are arranged around the axis of the movable disk, the moving grooves are provided with a sliding group, the sliding group is provided with an auxiliary block on the side away from the movable disk, the bottom of the auxiliary block is provided with a plurality of auxiliary wheels, the plurality of auxiliary wheels are equally distributed along the arc edge of the auxiliary block.

[0010] Preferably, the sliding assembly consists of a first sliding column, a second sliding column, and a third sliding column. The bottom of the moving disk is provided with a tightening groove, which is located on the side of the moving disk away from the first sliding column. The bottom of the moving disk is also provided with a plurality of extrusion grooves, which are located between two adjacent moving grooves. A limit groove is provided between the moving groove and the extrusion groove.

[0011] Preferably, a tightening column is slidably connected in the tightening groove, and an extrusion column is slidably connected in the extrusion groove. Rotating rollers are respectively provided at the bottom of the tightening column and the extrusion column. A linkage rod is provided between the first sliding column and the tightening column. Hinges are respectively provided between the second sliding column and the third sliding column and the extrusion column. A limit rod is provided at the center of the hinge rod, and the hinge rod is slidably connected to the limit groove through the limit rod.

[0012] Preferably, a spring is provided on the side of the sliding assembly near the axis of the moving disk, one end of the spring is connected to the side wall of the sliding assembly, and the other end of the spring is connected to the side wall of the moving groove, and a telescopic rod is provided inside the hinge rod.

[0013] Preferably, a conveying groove is provided on the side of the sliding group away from the moving disk, a flexible grinding belt is provided in the conveying groove, a transmission roller is provided in the conveying groove, a micro motor is provided in the conveying groove, the drive shaft of the micro motor is connected to the transmission roller, and the rotating roller at the bottom of the extrusion column and the rotating roller at the bottom of the tightening column are in contact with the flexible grinding belt respectively.

[0014] Preferably, the machine body is provided with an air pump and an air outlet, and the air pump is connected to the air outlet through a pipe;

[0015] Before the grinding device starts grinding, the first sliding column, the second sliding column, and the third sliding column are located at the end of the moving groove near the axis of the moving disk, the limiting rod is also located at the end of the limiting groove near the axis of the moving disk, and the tightening column is located at the end of the tightening groove away from the axis of the moving disk. Then the controller controls the micro motor inside the conveying groove to start, the drive shaft in the micro motor drives the transmission roller to rotate, and during the rotation of the transmission roller, the transmission roller drives the flexible grinding belt to rotate, and the flexible grinding belt then grinds the surface of the guide cone.

[0016] During the grinding process of the flexible grinding belt, the controller starts the hydraulic cylinder inside the machine body. The hydraulic rod in the hydraulic cylinder drives the moving disc to move. The moving disc moves towards the side closer to the grinding chamber. During the movement of the moving disc, the moving disc drives the sliding group, tightening column and extrusion column to move. At the same time as the moving disc moves, the auxiliary wheel at the bottom of the auxiliary block is always in contact with the surface of the guide cone. Since the surface of the guide cone is curved, the auxiliary wheel is affected by the curved surface of the guide cone, which causes the distance between the sliding group and the axis of the moving disc to continuously increase. Then the auxiliary wheel drives the auxiliary block to move, the auxiliary block drives the sliding group to move, and the sliding group then moves along the moving groove to the side away from the axis of the moving disc.

[0017] During the movement of the sliding group, the movement of the first sliding column drives the linkage rod to move. When the linkage rod moves, it drives the tightening column to move. The tightening column moves along the tightening groove towards the side closer to the axis of the moving disk. When the sliding group moves away from the axis of the guide cone, it drives the tightening column to move towards the side closer to the axis of the guide cone, so that the tightening column tightens the flexible grinding belt, so that the flexible grinding belt is always in a taut state, thereby improving the grinding quality of the guide cone.

[0018] When the second and third sliding columns move, they drive one end of the hinge rod to move. When one end of the hinge rod moves, it drives the limiting rod to move. The limiting rod moves along the limiting groove to the side away from the moving disk. When the limiting rod moves, it drives the other end of the hinge rod to move. The other end of the hinge rod then drives the extrusion column to move. The extrusion column moves along the extrusion groove to the side away from the axis of the moving disk. The extrusion column changes the extrusion force on the flexible grinding belt as the curvature of the guide cone changes, thereby ensuring that the grinding force of the flexible grinding belt on the guide cone is the same, thus improving the grinding quality of the guide cone.

[0019] By moving the sliding assembly under the action of the curved surface of the guide cone, the sliding assembly moves to the side away from the axis of the guide cone, thereby causing the sliding assembly to drive the extrusion column and the tightening column to move respectively. This achieves the tensioning of the flexible grinding belt by the extrusion column and the tightening column, thus realizing the adaptation of the flexible grinding belt to the curved surface grinding, thereby saving the grinding time of the guide cone and improving the grinding efficiency of the guide cone.

[0020] During the grinding process, the controller starts the air pump inside the machine. The air pump draws in outside air, which is then transported through a pipe to the air outlet. The air is then sprayed onto the surface of the guide cone through the air outlet, thus cleaning the surface of the guide cone. The impurities generated during grinding then fall into the impurity chamber.

[0021] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0022] 1. By moving the sliding assembly under the action of the curved surface of the guide cone, the sliding assembly moves to the side away from the axis of the guide cone, thereby causing the sliding assembly to drive the extrusion column and the tightening column to move respectively. This achieves the tensioning of the flexible grinding belt by the extrusion column and the tightening column, thus realizing the adaptation of the flexible grinding belt to the curved surface grinding, thereby saving the grinding time of the guide cone and improving the grinding efficiency of the guide cone.

[0023] 2. During the movement of the sliding group, the movement of the first sliding column drives the linkage rod to move. When the linkage rod moves, it drives the tightening column to move. The tightening column moves along the tightening groove towards the side closer to the axis of the moving disc. When the sliding group moves away from the axis of the guide cone, it drives the tightening column to move towards the side closer to the axis of the guide cone, so that the tightening column tightens the flexible grinding belt, keeping the flexible grinding belt in a taut state, thereby improving the grinding quality of the guide cone.

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.

[0035] Please see Figures 1-7 The present invention provides the following technical solution:

[0036] A fan guide cone grinding device with curved surface adaptation includes: a body 1, on one side of the body 1, a sliding door 11 is symmetrically arranged, the sliding door 11 is slidably connected to the body 1, a grinding table 12 is arranged inside the body 1, the grinding table 12 is rotatably connected to the body 1, and a grinding device 2 is also arranged inside the body 1, the grinding device 2 is slidably connected to the body 1, the grinding device 2 includes: a moving disk 21, the moving disk 21 is slidably connected to the body 1.

After the guide cone is fixed, the operator closes the sliding door 11, so that the polishing chamber 22 forms a sealed space. Then, the controller controls the motor to start, and the drive shaft in the motor drives the polishing table 12 to rotate. During the rotation of the polishing table 12, the polishing table 12 drives the guide cone to rotate. At the same time as the guide cone rotates, the controller controls the hydraulic cylinder to start. The hydraulic rod in the hydraulic cylinder drives the moving plate 21 to move. The moving plate 21 moves to the side closer to the polishing chamber 22. During the movement of the moving plate 21, the controller controls the polishing device 2 to start. The polishing device 2 then polishes the guide cone. Since the surface of the guide cone is curved, the polishing device 2 adaptively adjusts the polishing radius according to the curvature of the guide cone during the polishing process, so that the polishing device 2 can achieve curved surface polishing.

The bottom of the moving disk 21 is also provided with a plurality of extrusion grooves 28, which are located between two adjacent moving grooves 24. A limit groove is provided between the moving groove 24 and the extrusion groove 28.

[0041] In one specific embodiment of the present invention, a tightening column 271 is slidably connected in the tightening groove 27, and an extrusion column 281 is slidably connected in the extrusion groove 28. Rotating rollers are respectively provided at the bottom of the tightening column 271 and the extrusion column 281. A linkage rod 29 is provided between the first sliding column 251 and the tightening column 271. A hinge rod 30 is provided between the second sliding column 252 and the third sliding column 253 and the extrusion column 281, respectively. A limit rod is provided at the center of the hinge rod 30, and the hinge rod 30 is slidably connected to the limit groove through the limit rod.

[0042] In one specific embodiment of the present invention, a spring is provided on the side of the sliding assembly 25 near the axis of the moving disk 21. One end of the spring is connected to the side wall of the sliding assembly 25, and the other end of the spring is connected to the side wall of the moving groove 24. A telescopic rod is provided inside the hinge rod 30.

[0043] In one specific embodiment of the present invention, a conveying groove 254 is provided on the side of the sliding group 25 away from the moving disk 21. A flexible polishing belt 31 is provided in the conveying groove 254. A transmission roller is provided in the conveying groove 254. A micro motor (not shown in the figure) is provided in the conveying groove 254. The drive shaft of the micro motor is connected to the transmission roller (not shown in the figure). The rotating roller at the bottom of the extrusion column 281 and the rotating roller at the bottom of the tightening column 271 are in contact with the flexible polishing belt 31, respectively.

[0044] In one specific embodiment of the present invention, the body 1 is provided with an air pump (not shown in the figure) and an air outlet, and the air pump is connected to the air outlet through a pipe.

[0045] Before the grinding device 2 starts grinding, the first sliding column 251, the second sliding column 252 and the third sliding column 253 are located at one end of the moving groove 24 near the axis of the moving disk 21, and the limiting rod is also located at one end of the limiting groove near the axis of the moving disk 21. The tightening column 271 is located at one end of the tightening groove 27 away from the axis of the moving disk 21. Then the controller controls the micro motor inside the conveying groove 254 to start. The drive shaft in the micro motor drives the transmission roller to rotate. During the rotation of the transmission roller, the transmission roller drives the flexible grinding belt 31 to rotate. The flexible grinding belt 31 then grinds the surface of the guide cone.

[0046] During the grinding process of the flexible grinding belt 31, the controller controls the hydraulic cylinder in the machine body 1 to start. The hydraulic rod in the hydraulic cylinder drives the moving disk 21 to move. The moving disk 21 moves to the side closer to the grinding chamber 22. During the movement of the moving disk 21, the moving disk 21 drives the sliding group 25, the tightening column 271 and the extrusion column 281 to move. While the moving disk 21 moves, the auxiliary wheel at the bottom of the auxiliary block 26 is always in contact with the surface of the guide cone. Since the surface of the guide cone is curved, the auxiliary wheel is affected by the curved surface of the guide cone, which causes the distance between the sliding group 25 and the axis of the moving disk 21 to continuously increase. Then the auxiliary wheel drives the auxiliary block 26 to move, and the auxiliary block 26 drives the sliding group 25 to move. The sliding group 25 then moves along the moving groove 24 to the side away from the axis of the moving disk 21.

[0047] During the movement of the sliding assembly 25, the first sliding column 251 moves, driving the linkage rod 29 to move. When the linkage rod 29 moves, it drives the tightening column 271 to move. The tightening column 271 moves along the tightening groove 27 towards the side closer to the axis of the moving disk 21. When the sliding assembly 25 moves away from the axis of the guide cone, it drives the tightening column 271 to move towards the side closer to the axis of the guide cone, so that the tightening column 271 tightens the flexible grinding belt 31, so that the flexible grinding belt 31 is always in a taut state.

[0048] When the second sliding column 252 and the third sliding column 253 move, they drive one end of the hinge rod 30 to move. When one end of the hinge rod 30 moves, it drives the limiting rod to move. The limiting rod moves along the limiting groove to the side away from the moving disk 21. When the limiting rod moves, it drives the other end of the hinge rod 30 to move. The other end of the hinge rod 30 drives the extrusion column 281 to move. The extrusion column 281 moves along the extrusion groove 28 to the side away from the axis of the moving disk 21. The extrusion column 281 changes the extrusion force on the flexible grinding belt 31 as the curvature of the guide cone changes, thereby ensuring that the extrusion force of the flexible grinding belt 31 on the guide cone is the same.

[0049] As the sliding assembly 25 moves under the action of the guide cone curved surface, the sliding assembly 25 moves to the side away from the axis of the guide cone, thereby causing the sliding assembly 25 to drive the extrusion column 281 and the tightening column 271 to move respectively, thus realizing the tension of the flexible grinding belt 31 by the extrusion column 281 and the tightening column 271, thereby realizing the adaptation of the flexible grinding belt 31 to curved surface grinding.

[0050] During the grinding process, the controller controls the air pump inside the machine body 1 to start. The air pump draws in outside air, which is then transported to the air outlet through a pipe. The air is then sprayed onto the surface of the guide cone through the air outlet, thereby cleaning the surface of the guide cone. The impurities generated during grinding then fall into the impurity chamber 13.

[0051] Working principle of the invention:

[0052] The staff places the fan guide cone to be polished on the surface of the polishing table 12. Then, the clamping plate on the surface of the polishing table 12 fixes the fan guide cone. After the guide cone is fixed, the staff closes the sliding door 11, so that the polishing chamber 22 forms a sealed space. Then, the controller controls the motor to start. The drive shaft in the motor drives the polishing table 12 to rotate. During the rotation of the polishing table 12, the polishing table 12 drives the guide cone to rotate.

[0053] Before the grinding device 2 starts grinding, the first sliding column 251, the second sliding column 252 and the third sliding column 253 are located at one end of the moving groove 24 near the axis of the moving disk 21, and the limiting rod is also located at one end of the limiting groove near the axis of the moving disk 21. The tightening column 271 is located at one end of the tightening groove 27 away from the axis of the moving disk 21. Then the controller controls the micro motor inside the conveying groove 254 to start. The drive shaft in the micro motor drives the transmission roller to rotate. During the rotation of the transmission roller, the transmission roller drives the flexible grinding belt 31 to rotate. The flexible grinding belt 31 then grinds the surface of the guide cone.

[0054] During the grinding process of the flexible grinding belt 31, the controller controls the hydraulic cylinder in the machine body 1 to start. The hydraulic rod in the hydraulic cylinder drives the moving disk 21 to move. The moving disk 21 moves to the side closer to the grinding chamber 22. During the movement of the moving disk 21, the moving disk 21 drives the sliding group 25, the tightening column 271 and the extrusion column 281 to move. While the moving disk 21 moves, the auxiliary wheel at the bottom of the auxiliary block 26 is always in contact with the surface of the guide cone. Since the surface of the guide cone is curved, the auxiliary wheel is affected by the curved surface of the guide cone, which causes the distance between the sliding group 25 and the axis of the moving disk 21 to continuously increase. Then the auxiliary wheel drives the auxiliary block 26 to move, and the auxiliary block 26 drives the sliding group 25 to move. The sliding group 25 then moves along the moving groove 24 to the side away from the axis of the moving disk 21.

[0055] During the movement of the sliding assembly 25, the first sliding column 251 moves, driving the linkage rod 29 to move. When the linkage rod 29 moves, it drives the tightening column 271 to move. The tightening column 271 moves along the tightening groove 27 towards the side closer to the axis of the moving disk 21. When the sliding assembly 25 moves away from the axis of the guide cone, it drives the tightening column 271 to move towards the side closer to the axis of the guide cone, so that the tightening column 271 tightens the flexible grinding belt 31, so that the flexible grinding belt 31 is always in a taut state.

[0056] When the second sliding column 252 and the third sliding column 253 move, they drive one end of the hinge rod 30 to move. When one end of the hinge rod 30 moves, it drives the limiting rod to move. The limiting rod moves along the limiting groove to the side away from the moving disk 21. When the limiting rod moves, it drives the other end of the hinge rod 30 to move. The other end of the hinge rod 30 drives the extrusion column 281 to move. The extrusion column 281 moves along the extrusion groove 28 to the side away from the axis of the moving disk 21. The extrusion column 281 changes the extrusion force on the flexible grinding belt 31 as the curvature of the guide cone changes, thereby ensuring that the extrusion force of the flexible grinding belt 31 on the guide cone is the same.

[0057] As the sliding assembly 25 moves under the action of the guide cone curved surface, the sliding assembly 25 moves to the side away from the axis of the guide cone, thereby causing the sliding assembly 25 to drive the extrusion column 281 and the tightening column 271 to move respectively, thus realizing the tension of the flexible grinding belt 31 by the extrusion column 281 and the tightening column 271, thereby realizing the adaptation of the flexible grinding belt 31 to curved surface grinding.

[0058] During the grinding process, the controller controls the air pump inside the machine body 1 to start. The air pump draws in outside air, which is then transported to the air outlet through a pipe. The air is then sprayed onto the surface of the guide cone through the air outlet, thereby cleaning the surface of the guide cone. The impurities generated during grinding then fall into the impurity chamber 13.
