Technical Field

[0001] This invention relates to the field of filter housing polishing technology, specifically to a filter housing polishing device. Background Technology

[0002] As a component for filtering impurities or gases, automotive filters can effectively filter impurities in air or liquids. During the manufacturing process, the filter housing needs to be polished to shape its surface. Therefore, the quality of the polishing equipment determines the overall shaping quality.

[0003] For example, patent CN120170561A discloses a filter housing grinding and polishing device, which includes a frame. A protective cylinder with one end sealed is provided on the frame. A locking mechanism driven by a motor I is provided inside the protective cylinder. A filter housing is sleeved on the locking mechanism. A grinding mechanism and a cleaning mechanism are provided on the upper and lower sides of the filter housing inside the protective cylinder. A horizontally movable sealing mechanism is also provided at the open end of the protective cylinder. The locking mechanism includes a cylinder. Multiple sets of grooves are axially provided on the outer wall of the cylinder. A locking block with one end extending to the outside of the groove is inclinedly provided in the groove. A positioning shaft passing through the locking block is provided in the groove.

[0004] For example, patent CN116117606B discloses an automatic polishing device for filter housings, which includes a cylindrical internal support device. The left end of the internal support device is rotatably mounted on a bracket via a coaxially fixed sleeve, and the right end is connected to the output shaft of a geared motor via a coaxially mounted connecting shaft. The connecting shaft and the output shaft of the geared motor are detachably connected. The geared motor is mounted on a mounting plate that can slide left and right. The right end of the geared motor is connected to a telescopic device fixed on the mounting plate. A polishing mechanism is provided on one side of the internal support device. The internal support device includes a cover plate one, a ring, and a cover plate two arranged coaxially from left to right. The cover plate one and the ring, the rings and the ring and the cover plate two are all connected together by multiple circumferentially arranged connecting rods.

[0005] For example, the patent with publication number CN221539124U discloses a filter housing polishing device, which belongs to the technical field of filter production and processing equipment. It includes a base, a support plate on the base, a fixing mechanism on the support plate, an mounting plate on the top of the base, a rotating plate on the bottom of the mounting plate corresponding to the position of the support plate, and a polishing mechanism on the rotating plate. The support plate is connected to the base through a first rotating rod, and the bottom end of the first rotating rod extends downward to the bottom of the base and is fixedly fitted with a first gear. The rotating plate is connected to the mounting plate through a second rotating rod, and the top end of the second rotating rod extends upward to the top of the mounting plate and is fixedly fitted with a second gear. The filter housing is fixed on the support plate by the fixing mechanism, and the outer wall of the filter housing is polished by the polishing mechanism.

[0006] Most of the existing technologies mentioned above improve the overall structure. However, existing filter housing grinding equipment mostly requires manual positioning by the user during operation. After installing the automotive filter housing to be processed, the grinding operation is carried out. It cannot automatically process the multi-directional uniformity after positioning, thus having certain limitations in use. Summary of the Invention

[0007] The purpose of this invention is to provide a filter housing grinding device to solve the problem in the background art that most of them require manual positioning by the user, and the grinding operation is carried out after the automotive filter housing to be processed is installed. They cannot adaptively perform multi-directional uniform automatic processing after positioning.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a filter housing grinding device, comprising a grinding docking roller connected to the middle end of a base via a preset motor; a first gear fixedly connected to the lower end of the grinding docking roller; a second gear rotatably connected to the inner side of the base, the second gear meshing with the first gear; a nested docking component nested on the outer side of the base, the outer side of the nested docking component being fitted with the filter housing workpiece to be processed; an adaptive movable guide structure is provided between the base and the nested docking component, the adaptive movable guide structure enabling multi-directional reciprocating contact between the docked workpiece and the grinding docking roller.

[0009] Furthermore, the adaptive active guiding structure is provided with a docking transmission disk, and the lower end of the docking transmission disk is docked with a docking transmission disk. The lower end of the docking transmission disk is rotatably connected to a guide docking rod, which runs through the inner side of the base. The end of the guide docking rod is rotatably connected to the lower end of the nested docking member. A reserved docking disk is fixedly connected to the outer side of the lower end of the nested docking member.

[0010] Furthermore, the fixed rack is fixedly connected to the inner side of the base, and the outer side of the reserved docking plate is rotatably connected to a docking limiting member. A return spring is fixedly connected to the outer side of the docking limiting member, and the return spring is docked with the inner side of the reserved docking plate. At the same time, the docking limiting member and the fixed rack are in corresponding contact.

[0011] Furthermore, the first gear drives the outer second gear and the docking transmission disk to rotate synchronously, and the docking transmission disk drives the nested docking parts to reciprocate along the inner side of the base through the guide docking rod to form a transverse moving structure, and the nested docking parts are symmetrically distributed about the center point of the base.

[0012] Furthermore, during the lateral movement of the nested docking component, the reserved docking plate on its outer side synchronously contacts the fixed rack and rotates, and the fixed rack and the reserved docking plate in the inward movement state are engaged and rotated through the docking limiting component; the docking limiting component is reset through the return spring and the inner side of the reserved docking plate.

[0013] Furthermore, an auxiliary locking structure is provided on the inner side of the nested docking member to prevent misalignment of the workpiece carried on the outer side of the nested docking member; the auxiliary locking structure is provided with a fixed guide member, which is fixedly connected to the inner side of the base; a built-in liquid bladder is nested at the lower inner end of the nested docking member; a supply pipe passes through the outer side of the built-in liquid bladder and passes through the inner side of the nested docking member.

[0014] Furthermore, an external liquid bladder is bonded to the inner side of the upper end of the nested docking member, and a limiting reserved part is docked to the outer side of the external liquid bladder. The limiting reserved part is symmetrically distributed about the center point of the nested docking member, and the external liquid bladder is connected to the supply pipe.

[0015] Furthermore, during the lateral movement of the nested docking member, the built-in liquid bladder on its inner side simultaneously contacts the fixed guide member, and the built-in liquid bladder is pressurized and supplies liquid to the outer liquid bladder through the supply pipe along the inside of the nested docking member.

[0016] Furthermore, when the external liquid bladder expands under pressure, it pushes the outer limiting reserved member to move laterally, and the limiting reserved member forms a nested structure along the inner side of the nested docking member, and the limiting reserved member is symmetrically distributed about the center point of the nested docking member.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This filter housing grinding equipment is equipped with an adaptive movable guide structure. Through the adaptive movable guide structure, the workpiece and the grinding docking roller are made into multi-directional reciprocating contact. The drive motor drives the brush-type grinding docking roller and the first gear to rotate. During the rotation of the first gear, the second gear on the outside and the docking transmission disk will rotate synchronously. The lower end of the docking transmission disk will rotate with its circumference. Through the guide docking rod, the nested docking parts will reciprocate along the inner side of the base to form a transverse movable structure. This allows the nested workpiece on the outside to reciprocate to contact the brush-type grinding docking roller. With the adaptive rotation structure, the surface of the workpiece is uniformly and adaptively treated with the brush-type grinding docking roller.

[0019] Furthermore, as the nested docking component reciprocates along the inner side of the base via the power transmission of the guide docking rod, the reserved docking plate on its lower outer side will engage with the fixed rack and rotate. When the fixed rack contacts the reserved docking plate in an inwardly moving lateral state, the docking limiting component on the outer side of the reserved docking plate will be in a rotating state engaged with the fixed rack. When the reserved docking plate resets outward with the nested docking component, the docking limiting component on its outer side will disengage from the fixed rack through the elastic support of the reset spring. With the reciprocating movement of the equipment, the workpiece on the outer side of the nested docking component is evenly driven to contact the grinding docking roller for surface treatment without dead angles. No manual positioning is required from the user. After the required automotive filter housing is installed, the device can automatically perform active grinding operation and achieve multi-directional uniform automatic processing after adaptive positioning, thus improving the practicality of the device.

[0020] Furthermore, an auxiliary locking structure is provided to prevent misalignment of the workpiece carried on the outside of the nested docking piece. During the lateral movement of the nested docking piece, its lower end will reciprocate to contact the fixed guide, thereby pressurizing the built-in liquid bladder on its inner side through the fixed guide. When the built-in liquid bladder is pressurized, it will supply liquid to the outer liquid bladder through the supply pipe along the inside of the nested docking piece. Then, the expanded outer liquid bladder will push the outer limit reservation piece to move laterally, thereby adaptively positioning and locking the inner side of the workpiece nested on the outside of the nested docking piece. This avoids misalignment or slippage during surface treatment and improves the processing quality of the device. Attached Figure Description

[0031] 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.

[0032] Example 1: Please refer to Figures 1-9 The present invention provides the following technical solution: a filter housing grinding device, which solves the drawback of requiring manual positioning by the user and installation of the automotive filter housing to be processed before grinding. The device discloses a base 1 with a grinding roller 2 connected to its middle end via a pre-set motor; a first gear 3 is fixedly connected to the lower end of the grinding roller 2; a second gear 4 is rotatably connected to the inner side of the base 1, and the second gear 4 meshes with the first gear 3; a nested docking piece 7 is nested on the outer side of the base 1, and the filter housing workpiece to be processed is sleeved on the outer side of the nested docking piece 7; an adaptive movable guide structure is provided between the base 1 and the nested docking piece 7, which enables multi-directional reciprocating contact between the docked workpiece and the grinding roller 2.

[0033] The adaptive activity guidance structure is equipped with a docking transmission disk 5, and the lower end of the docking transmission disk 5 is docked with another docking transmission disk 5. The lower end of the docking transmission disk 5 is rotatably connected to a guide docking rod 6, which runs along the inner side of the base 1. The end of the guide docking rod 6 is rotatably connected to the lower end of the nested docking member 7. A reserved docking disk 8 is fixedly connected to the outer side of the lower end of the nested docking member 7. A fixed rack 9 is fixedly docked to the inner side of the base 1. A docking limiting member 10 is rotatably connected to the outer side of the reserved docking disk 8, and a return spring 11 is fixedly connected to the outer side of the docking limiting member 10. The return spring 11 is docked with the inner side of the reserved docking disk 8. At the same time, the docking limiting member 10 and the fixed rack 9 are in corresponding contact. The first gear 3 drives the outer side... The second gear 4 and the docking transmission disk 5 rotate synchronously. The docking transmission disk 5 drives the nested docking piece 7 to reciprocate along the inner side of the base 1 through the guide docking rod 6, forming a transverse movable structure. The nested docking pieces 7 are symmetrically distributed about the center point of the base 1. During the transverse movement of the nested docking piece 7, the reserved docking disk 8 on its outer side simultaneously contacts the fixed rack 9 and rotates. The fixed rack 9 and the reserved docking disk 8 in the inward moving state are engaged and rotated through the docking limit member 10. The docking limit member 10 is reset through the return spring 11 and the inner side of the reserved docking disk 8. After the filter housing workpiece to be processed is sleeved on the outer side of the nested docking piece 7, the motor can be driven to drive the brush-type grinding plate. The receiving roller 2 and the first gear 3 rotate. During the rotation of the first gear 3, the outer second gear 4 and the docking transmission disk 5 will rotate synchronously. As the docking transmission disk 5 rotates, the guide docking rod 6 drives the nested docking piece 7 to reciprocate along the inner side of the base 1, forming a transverse moving structure. This allows the nested workpiece on the outer side to reciprocate in contact with the brush-type grinding docking roller 2. With the adaptive rotation structure, the workpiece surface is uniformly and adaptively surface-treated with the brush-type grinding docking roller 2. During the reciprocating movement of the nested docking piece 7 along the inner side of the base 1 through the transmission of force from the guide docking rod 6, the reserved docking disk 8 on the outer side of its lower end will contact the meshing of the fixed rack 9 and rotate. When the fixed rack 9 contacts the reserved docking plate 8 which is in an inwardly moving lateral state, the docking limiting member 10 on the outside of the reserved docking plate 8 will be in a rotating state that meshes with the fixed rack 9. When the reserved docking plate 8 is reset outward along with the nested docking member 7, the docking limiting member 10 on its outside will be released from the meshing state with the fixed rack 9 through the elastic support of the reset spring 11. With the reciprocating movement of the equipment, the workpiece on the outside of the nested docking member 7 is uniformly driven to contact the grinding docking roller 2 without dead angles for surface treatment. There is no need for the user to perform extra manual positioning. After the required automotive filter housing is installed, the active grinding operation can be performed adaptively, and multi-directional uniform automatic processing can be achieved after adaptive positioning.

[0034] Example 2: Based on Example 1, to address the problem of the inability to adaptively perform multi-directional uniform automatic processing after positioning, an auxiliary locking structure is also disclosed, the specific structure of which is as follows:

[0035] An auxiliary locking structure is provided on the inner side of the nested docking part 7, which is used to lock the workpiece carried on the outer side of the nested docking part 7 to prevent misalignment.

[0036] The auxiliary locking structure is equipped with a fixed guide 12, which is fixedly connected to the inner side of the base 1. A built-in liquid bladder 13 is nested at the lower inner end of the nested docking member 7. A supply pipe 14 passes through the outer side of the built-in liquid bladder 13 and runs along the inner side of the nested docking member 7. An outer liquid bladder 15 is bonded to the inner upper end of the nested docking member 7, and a limit stop 16 is connected to the outer side of the outer liquid bladder 15. The limit stop 16 is symmetrically distributed about the center point of the nested docking member 7. The outer liquid bladder 15 and the supply pipe 14 are interconnected. During the lateral movement of the nested docking member 7, the built-in liquid bladder 13 on its inner side simultaneously contacts the fixed guide 12, and the built-in liquid bladder 13, under pressure, supplies liquid to the outer liquid bladder 15 through the supply pipe 14 along the interior of the nested docking member 7. When the external liquid bladder 15 expands under pressure, it pushes the outer limiting pre-reserved part 16 to move laterally. The limiting pre-reserved part 16 forms a nested structure along the inner side of the nested docking part 7, and the limiting pre-reserved part 16 is symmetrically distributed about the center point of the nested docking part 7. During the lateral movement of the nested docking part 7, its lower end will reciprocate to contact the fixed guide 12, thereby applying pressure to the inner liquid bladder 13 through the fixed guide 12. When the inner liquid bladder 13 is compressed, it will supply the external liquid bladder 15 through the supply pipe 14 along the inside of the nested docking part 7. Then, the expanded external liquid bladder 15 pushes the outer limiting pre-reserved part 16 to move laterally, thereby performing adaptive positioning and locking treatment on the inner side of the workpiece sleeved on the outer side of the nested docking part 7, avoiding misalignment or slippage during the surface treatment process.
