Description

Technical Field

[0001] The invention relates to a spray cleaning device used for permanent ferrite grinding processing, and belongs to the field of permanent ferrite processing. Background Art

[0002] During the grinding process of permanent magnet ferrite materials, a large amount of chips will be generated, which will not only affect the processing accuracy and workpiece surface quality, but also cause increased tool wear. In order to improve processing efficiency, extend tool life and ensure the stability of the processing process, it is necessary to use a spray cleaning device during the processing. The existing spray cleaning device still has some shortcomings.

[0003] The invention patent with publication number CN103111443B discloses a spray automatic cleaning device, including: a main body, a water wheel, a needle bearing, a thrust bearing, an end cover, a brush body, and a column; the inner ring of the water wheel is sleeved on the connecting column of the main body, and the inner ring of the water wheel and the connecting column of the main body are connected through a needle bearing; the column is threadedly connected to the connecting column of the main body; the thrust bearing is sleeved on the outer ring of the water wheel, and the connecting ring of the end cover is threadedly connected to the lower end of the inner wall of the main body; the ring of the brush body is threadedly connected to the lower end of the outer ring of the water wheel, and the positioning platform of the outer ring of the water wheel is pressed tightly against the inner ring of the thrust bearing. The device has a simple structure and is easy to use. It uses the water pressure of the incoming water as the power for the rotation of the brush body. There is no need to provide an additional power source for the rotation of the brush body. It is energy-saving and environmentally friendly, and at the same time realizes spray cleaning of the environment, instruments, and equipment. Although the above-mentioned device can use water flow to provide power for the rotation of the brush, it cannot break up or gather magnetic debris during use, which is not conducive to subsequent centralized cleaning. Moreover, it cannot reduce the flow rate loss while adjusting the degree of water flow diffusion through a multi-stage guide structure, which affects the cleaning effect.

[0004] Therefore, we have made improvements to this problem and proposed a spray cleaning device for permanent ferrite grinding. Summary of the invention

[0005] (I) The technical problem to be solved by the present invention is that the existing spray cleaning device cannot disperse or gather magnetic debris, which is not conducive to subsequent centralized cleaning, and cannot reduce the flow rate loss while adjusting the water flow diffusion degree through a multi-level guide structure.

[0006] (II) Technical solution In order to achieve the above-mentioned invention object, the present invention provides a spray cleaning device for permanent magnet ferrite grinding processing, including a shell, a support assembly is installed on the outer side of the shell, a block is installed on the shell, a fixed plate is fixedly connected to the block, a waterproof motor housing is fixedly provided on the fixed plate, a baffle is installed on the waterproof motor housing, a turntable is rotatably provided in the middle of the fixed plate, a pressure rod is fixedly connected to the turntable, a sliding assembly is installed on the fixed plate between two adjacent pressure rods, a push rod is installed on the sliding assembly, a ball shaft is fixedly connected to the push rod, a shaft sleeve is rotatably provided on the outer side of the ball shaft, a guide plate is installed on the shaft sleeve, a fixed block is fixedly connected to the fixed plate, and the guide plate and the fixed block are rotatably connected.

[0007] The support assembly includes a first connection shell fixedly connected to the outer shell, a second connection shell is fitted on the outer side of the first connection shell, and support blocks are fixedly connected around the second connection shell.

[0008] The height of the first connecting shell is greater than that of the second connecting shell. The first connecting shell and the second connecting shell are spherical cover structures with cut surfaces on both upper and lower sides. The outer shell forms a first rotating structure through the first connecting shell and the second connecting shell.

[0009] The fixing plate, the stopper and the outer shell are fixedly connected to form an integral structure, the stopper is evenly distributed along the circumference of the fixing plate, and the side surfaces of the stopper and the side surfaces of the guide plate are in contact with each other.

[0010] Among them, a connecting cover is fixedly arranged on the fixing plate, and the side of the connecting cover away from the fixing plate is arranged as a rounded structure, the diameter of the connecting cover decreases from the side close to the fixing plate to the side away from the fixing plate, a bottom plate is fixedly arranged at the bottom of the fixing plate, and a connecting pipe is fixedly connected to the middle of the bottom plate.

[0011] Wherein, the sliding assembly comprises an adjusting block slidably mounted on the fixing plate, a rotating shaft is rotatably mounted on the adjusting block, and the push rod is rotatably connected to the rotating shaft.

[0012] Among them, a slider is fixedly connected to the bottom of the adjustment block, a movable groove for the slider to move is opened on the fixed plate, the inner wall of the movable groove and the outer wall of the slider fit each other, and the adjustment block and the pressure rod are alternately distributed on the fixed plate.

[0013] The adjusting block forms a sliding structure with the fixed plate through the rotating disk and the pressure rod, and a spring is fixedly arranged between the sliding block and the fixed plate.

[0014] The guide plates and the stoppers are alternately distributed on the fixing plate, a chamfered structure is provided on one side of the fixing plate close to the waterproof motor housing, and a gap exists between the fixing plate and the housing.

[0015] Wherein, a connecting shaft is fixedly arranged on the fixed block, the guide plate and the connecting shaft are rotationally connected, and the guide plate and the fixed block form a second rotating structure through the push rod, the ball shaft and the sleeve.

[0016] (III) Beneficial effects The spray cleaning device for permanent ferrite grinding provided by the present invention has the following beneficial effects: When the rotary table rotates clockwise, the adjusting block will automatically gather under the action of the spring, driving the push rod to move toward the position of the central axis of the device. At this time, the ball shaft will pull the guide plate on the sleeve to rotate, so that the water flow of the device is gathered during spraying. When the rotary table rotates counterclockwise, the adjusting block will be moved away from the central axis of the device, so that the push rods at various locations are diffused outward, and the push rod pushes the sleeve through the ball shaft, so that the guide plates at various positions rotate in the opposite direction, so that the water flow of the device is diffused during spraying, so that the device can switch between gathering and dispersing magnetic debris, thereby enhancing the adaptability of the device and solving the problem that the existing spray cleaning device is not conducive to subsequent centralized cleaning of debris.

[0017] 2. By setting blocks that are distributed alternately with the guide plates, the device can prevent water from flowing out of the gap between two adjacent guide plates while guiding the flow, thereby ensuring the water flow regulation effect of the device. The existing equipment uses multiple protruding structures on the outside of a disc, which can achieve the diversion function, but the accuracy is insufficient. The device ensures that the water flow diversion angle can be adjusted while avoiding the formation of gaps between two adjacent diversion areas, thereby ensuring the cleaning effect of the device.

[0018] 3. The multi-stage guiding function is realized by setting the outer shell, the fixed plate and the connecting cover. The fluid will be evenly dispersed to the internal space of the outer shell through the rounded structure of the connecting cover, and will be transported to the guide plate through the gap between the outer shell and the fixed plate and the chamfered structure on the fixed plate, realizing the multi-stage guiding function, reducing the flow velocity loss of the fluid as much as possible, thereby improving the cleaning effect of the device, and solving the problem that the existing spray cleaning device cannot reduce the flow velocity loss while adjusting the water flow diffusion degree through the multi-stage guiding structure. The device has the advantage of better cleaning effect.

[0019] 4. The device is provided with a support assembly, and the first connecting shell on the support assembly can rotate inside the second connecting shell, so that the angle of the outer shell and the fixing plate changes, thereby changing the angle of water flow gathering or diffusion of the device to adapt to the use of permanent ferrites of different shapes, thereby enhancing the applicability of the device.

DETAILED DESCRIPTION

[0023] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples of the specification. The following examples are only used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] Embodiment 1: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, this embodiment proposes a spray cleaning device for permanent ferrite grinding, including a shell 1, a support assembly 2 is installed on the outer side of the shell 1, and the support assembly 2 is used to adjust the direction of the shell 1 so as to subsequently clean the permanent ferrites of different structures, thereby enhancing the adaptability of the device. A stopper 17 is installed on the shell 1, and a fixing plate 3 is fixedly connected to the stopper 17. The stopper 17 is used to connect the shell 1 and the fixing plate 3, while ensuring that a certain gap is reserved between the shell 1 and the fixing plate 3 for water to flow through. A waterproof motor housing 6 is fixedly provided on the fixing plate 3, and a waterproof motor housing 6 is installed on the waterproof motor housing 6. There is a baffle 7, and a turntable 8 is rotatably arranged in the middle of the fixed plate 3. Later, a motor can be installed in the waterproof motor housing 6, and the turntable 8 is connected through the motor output shaft, so as to drive the turntable 8 to rotate. A pressure rod 9 is fixedly connected to the turntable 8, and a sliding assembly 10 is installed on the fixed plate 3 between two adjacent pressure rods 9. A push rod 11 is installed on the sliding assembly 10, and a ball shaft 12 is fixedly connected to the push rod 11. A shaft sleeve 13 is rotatably arranged on the outer side of the ball shaft 12, and a guide plate 14 is installed on the shaft sleeve 13. A fixed block 15 is fixedly connected to the fixed plate 3, and the guide plate 14 and the fixed block 15 are rotatably connected. When the turntable 8 rotates, as shown in FIG. Figure 2As shown, the side of the pressure rod 9 will act on the sliding component 10, so that the sliding component 10 drives the push rod 11 to move away from the central axis of the device, and the push rod 11 pushes the ball shaft 12, and the ball shaft 12 rotates in the sleeve 13 and drives the guide plate 14 to rotate, thereby expanding the cleaning range of the device. The turntable 8 can also be rotated in the opposite direction so that the push rod 11 moves toward the central axis of the device when the guide plate 14 is under pressure, thereby reducing the cleaning range of the device. The device can realize the function of gathering or dispersing magnetic debris by gradually expanding or reducing the cleaning range, so as to facilitate the subsequent centralized treatment of the magnetic debris.

[0025] Embodiment 2: The solution in Example 1 is further introduced below in combination with a specific working method, as described below: like Figure 1 , Fig.12 and Fig.13 As shown, as a preferred embodiment, on the basis of the above method, further, the support assembly 2 includes a first connecting shell 201 fixedly connected to the outer shell 1, a second connecting shell 202 is fitted on the outer side of the first connecting shell 201, and support blocks 203 are fixedly connected on all four sides of the second connecting shell 202. The first connecting shell 201 can rotate inside the second connecting shell 202, thereby changing the orientation of the outer shell 1, and further changing the cleaning position and cleaning angle of the device.

[0026] like Fig.13 As shown, as a preferred embodiment, on the basis of the above method, further, the height of the first connecting shell 201 is greater than the height of the second connecting shell 202, the first connecting shell 201 and the second connecting shell 202 are spherical cover structures with cut surfaces on the upper and lower sides, and the outer shell 1 forms a first rotating structure between the first connecting shell 201 and the second connecting shell 202. The first connecting shell 201 and the second connecting shell 202 of the spherical cover structure enable the first connecting shell 201 to not only adjust the angle in the second connecting shell 202, but also rotate around its own central axis, so that the water flow maintains progressive gathering while gathering, so as to facilitate the subsequent gathering or dispersion of magnetic debris.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the fixed plate 3, the block 17 and the shell 1 are fixedly connected as an integral structure to ensure the overall stability of the device, and the block 17 is evenly distributed along the circumference of the fixed plate 3, and the side of the block 17 is in contact with the side of the guide plate 14. The block 17 ensures that the water flow will not leak from between two adjacent guide plates 14, so that the device can keep the water flow stably dispersed or gathered.

[0028] like Figure 6 and Figure 7 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a connecting cover 18 is fixedly provided on the fixed plate 3, and the side of the connecting cover 18 away from the fixed plate 3 is set as a rounded structure, and the diameter of the connecting cover 18 decreases from the side close to the fixed plate 3 to the side away from the fixed plate 3, so as to ensure that the connecting cover 18 can stably guide the cleaning water, and a bottom plate 4 is fixedly provided at the bottom of the fixed plate 3, and a connecting pipe 5 is fixedly connected in the middle of the bottom plate 4, and the cleaning water is pumped into the device from the middle position of the bottom plate 4 by connecting an external water pump at the connecting pipe 5, and the water flow is guided by the connecting cover 18 so that the water flow is evenly dispersed.

[0029] like Figure 1 and Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, the sliding assembly 10 includes an adjusting block 1001 slidably mounted on the fixed plate 3, and a rotating shaft 1002 is rotatably mounted on the adjusting block 1001. The push rod 11 and the rotating shaft 1002 are rotatably connected. When the adjusting block 1001 moves, the rotating shaft 1002 will push the push rod 11 to move. When the push rod 11 moves toward or away from the center axis of the device, the push rod 11 can push or pull the diversion structure on the device to facilitate the subsequent adjustment of the diversion effect of the device.

[0030] like Figure 1 , Figure 2 and Figure 8 As shown, as a preferred embodiment, on the basis of the above method, further, the bottom of the adjustment block 1001 is fixedly connected with a slider 1003, and a movable groove 19 for the slider 1003 to move is opened on the fixed plate 3, and the inner wall of the movable groove 19 and the outer wall of the slider 1003 fit each other, and the adjustment blocks 1001 and the pressure rods 9 are alternately distributed on the fixed plate 3, and each pressure rod 9 corresponds to an adjustment block 1001, so that the device can synchronously adjust the positions of multiple adjustment blocks 1001, and the slider 1003 in the movable groove 19 keeps the adjustment block 1001 straight when moving.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the adjusting block 1001 forms a sliding structure with the fixed plate 3 through the turntable 8 and the pressure rod 9, and a spring 1004 is fixedly arranged between the slider 1003 and the fixed plate 3. The sliding structure on the device enables the adjusting block 1001 to be pushed to move through the pressure rod 9 when the turntable 8 rotates, and the spring 1004 can reset the adjusted slider 1003 and the adjusting block 1001 so as to subsequently reduce the spray range of the device.

[0032] like Figure 6 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the guide plate 14 and the block 17 are alternately distributed on the fixed plate 3, and a chamfered structure is provided on the side of the fixed plate 3 close to the waterproof motor housing 6, and there is a gap between the fixed plate 3 and the outer shell 1. The gap between the fixed plate 3 and the outer shell 1 can be used for fluid spraying, so as to clean the magnetic blocks during the processing. The fixed plate 3 with the chamfered structure cooperates with the block 17 to realize the diversion function, so as to reduce the flow velocity loss of the water flow in the device.

[0033] like Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a connecting shaft 16 is fixedly provided on the fixed block 15, and the guide plate 14 is rotationally connected to the connecting shaft 16. The guide plate 14 forms a second rotation structure with the fixed block 15 through the push rod 11, the ball shaft 12 and the sleeve 13. When the push rods 11 at various locations diffuse outward, the ball shaft 12 on the push rod 11 will push the sleeve 13 outward, thereby rotating the guide plate 14, thereby realizing the function of diffusing the water flow. On the contrary, when multiple push rods 11 gather synchronously to the middle of the device, the ball shaft 12 will pull the sleeve 13, thereby causing the guide plate 14 to rotate in the opposite direction, thereby gathering the water flow, so that the magnetic debris can be gathered and cleaned up later.

[0034] Embodiment 3: The schemes in Example 1 and Example 2 are further introduced below in combination with specific working methods, as described below for details: Specifically, the spray cleaning device for permanent ferrite grinding is used as follows: Figure 1 , Fig.12 and Fig.13 As shown, the support assembly 2 is used to adjust the orientation of the outer shell 1 so as to clean permanent magnetic ferrites of different structures. The support block 203 is used to support the second connecting shell 202. The first connecting shell 201 can rotate inside the second connecting shell 202 to change the orientation of the outer shell 1, thereby changing the cleaning position and cleaning angle of the device. Since the first connecting shell 201 and the second connecting shell 202 are spherical cover structures with cut surfaces on both the upper and lower sides, the first connecting shell 201 can not only adjust the angle inside the second connecting shell 202, but also rotate around its own central axis. When the water flow gathers, the outer shell 1 is rotated, so that the water flow can gather magnetic debris from different areas.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, the block 17 is used to connect the housing 1 and the fixing plate 3, and at the same time ensure that a gap for water flow is formed between the housing 1, the fixing plate 3, the block 17 and the guide plate 14. An external water pump is connected to the connecting pipe 5 to pump the cleaning water into the device from the middle position of the bottom plate 4. The connecting cover 18 is used to guide the water flow so that the water flow is evenly dispersed. Figure 6 and Figure 7 It can be seen that, since the tip of the connection cover 18 is a rounded structure, and the diameter of the connection cover 18 decreases from the side close to the fixed plate 3 to the side away from the fixed plate 3, the connection cover 18 can stably guide the cleaning water so that the water flow is evenly dispersed. The device can gradually adjust the dispersion degree of the water flow during spraying. The motor is installed in the waterproof motor housing 6, and the motor output shaft is connected to the turntable 8 and drives the turntable 8 to rotate. When the turntable 8 rotates, it will drive the pressure rod 9 to make a circular motion. Figure 2 As shown, the side of the pressure rod 9 will act on the adjustment block 1001 on the sliding assembly 10. The adjustment block 1001 is straight on the fixed plate 3 through the movable groove 19 and the slider 1003. When the adjustment block 1001 moves, it will drive the rotating shaft 1002 to push the push rod 11 to move. When the push rod 11 moves toward or away from the center axis of the device, the push rod 11 will push or pull the ball shaft 12 on the device. When the push rod 11 pushes the ball shaft 12, the ball shaft 12 rotates in the shaft sleeve 13 and drives the guide plate 14 to rotate, thereby expanding the cleaning range of the device, and also making the turntable 8 rotate in the opposite direction. Under the action of the spring 1004, the adjustment blocks 1001 at each position move toward the direction close to the center axis of the device. At this time, the push rod 11 moves toward the center axis of the device, thereby reducing the cleaning range of the device. The magnetic debris is dispersed or gathered by gradually expanding or reducing the cleaning range, thereby centrally processing the magnetic debris.

[0036] The above embodiments are only used to illustrate the present invention, but not to limit the present invention. Although the present invention is described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
