Description

Technical Field

[0001] This invention relates to the field of filter processing, and in particular to a filter housing polishing device. Background Technology

[0002] A filter is an accessory that uses filter paper to filter impurities or gases. It generally refers to automotive filters, which are engine components. A filter mainly consists of a housing and a filter element. The filter element is the primary filtration component, responsible for filtering the gas, while the housing provides necessary protection for the filter element. During filter manufacturing, the housing is formed using automated stamping equipment. After processing, the inside of the housing needs to be polished to ensure a tight fit when the filter element is installed inside.

[0003] Specifically, a polishing device for processing filter housings, patent number CN221583189U, has the following defects when polishing the inner wall of the filter housing: it adjusts the polishing roller in the drive polishing device to move laterally at a fixed distance so that the polishing roller is inserted into the inner wall of the housing and in close contact with it. At the same time, the motor drives the polishing device to rotate the polishing roller and polish the inner wall of the housing. However, at this time, the distance between the polishing roller and the motor output shaft is fixed, but the inner wall of the housing may be uneven. Therefore, the polishing roller may not be able to fully contact the inner wall of the housing in different directions during the rotation process, thus affecting the polishing effect. Summary of the Invention

[0004] The purpose of this invention is to provide a filter housing polishing device.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0006] A filter housing polishing device includes a machine base and a housing mounted on top of the machine base. A cylinder extending to the bottom of the machine base is housed within the housing. A sleeve is screwed into the cylinder. A locking mechanism penetrating the side wall of the sleeve is provided on the cylinder. A cover extending from the top of the cylinder into its opening is provided at the bottom of the cylinder to support the sleeve. A fixing plate driven vertically by a hydraulic rod is radially provided on the outer wall of the cover. An air outlet pipe is provided on the side wall of the cover. A motor is also provided at the bottom of the cover. The output shaft of the motor is connected to a mounting rod inside the sleeve. A fan blade is provided on the motor output shaft. A C-shaped rod penetrating its side wall is provided on the mounting rod. A grinding rod is provided at one end of the C-shaped rod. A spring is sleeved on the C-shaped rod between the grinding rod and the mounting rod.

[0007] Preferably, the inner diameter of the opening end of the cover is smaller than the inner diameter of the sleeve, and the fan blade is disposed on the motor output shaft inside the opening of the cover.

[0008] Preferably, the mounting rod is provided with a through hole for the C-shaped rod to pass through, the two ends of the C-shaped rod are connected by a strip plate, the strip plate is provided with bolts for locking and fixing the grinding rod, the back of the strip plate is provided with a magnetic seat corresponding to the mounting rod, and the magnetic seat is covered with an insulating cover made of polyethylene material.

[0009] Preferably, a dust collector bag is fixed to the air outlet pipe by a clamp, and a box for accommodating the dust collector bag is provided on the side wall of the cover.

[0010] Preferably, the top of the sleeve is fitted with a limiting ring located above the cylinder, the bottom of the sleeve is higher than the horizontal plane of the bottom of the cylinder, and the cylinder is fixedly connected to the machine base.

[0011] Preferably, the locking mechanism includes an electric push rod disposed on the outer wall of the top of the cylinder, an extrusion rod disposed on the output shaft of the electric push rod, and mounting holes for the corresponding extrusion rods to pass through are provided on the side walls of the cylinder and the sleeve.

[0012] The beneficial effects of this invention are as follows: This invention uses a motor to drive the mounting rod, the C-shaped rod, the strip plate, and the grinding rod to rotate inside the filter housing. The grinding rod, which is in contact with the inner wall of the housing, can perform grinding and polishing work. At this time, under the influence of the spring's extension force, the strip plate is pushed to keep the grinding rod in contact with the inner wall of the housing. This allows the position of the grinding rod to be automatically adjusted slightly under the influence of the spring's extension force and to fully contact the inner wall of the housing. This allows the grinding rod to fully grind the inner wall of the filter housing. During the grinding process, the output shaft of the motor also drives the fan blades to rotate, thereby generating a strong suction force to draw the grinding debris obtained inside the housing downward into the cover, and finally guide it into the dust collector bag for filtration through the air outlet pipe.

Detailed Implementation

[0017] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] A filter housing polishing device includes a machine base 1 and a housing 2 disposed on the top of the machine base 1. A cylinder 3 extending to the bottom of the machine base 1 is disposed inside the housing 2. A sleeve 4 is screwed into the cylinder 3. A locking mechanism 5 penetrating the side wall of the sleeve 4 is disposed on the cylinder 3.

[0019] The bottom of the cylinder 3 is provided with a cover 6 that extends to its opening to support the sleeve 4. The outer wall of the cover 6 is provided with a fixing plate 8 that is driven vertically by a hydraulic rod 7. The side wall of the cover 6 is provided with an air outlet pipe 9. A dust collector bag is fixed to the air outlet pipe 9 by a clamp. The side wall of the cover 6 is provided with a box for accommodating the dust collector bag.

[0020] The bottom of the cover 6 is also provided with a motor 10. The output shaft of the motor 10 is connected to the mounting rod 11 inside the sleeve. The output shaft of the motor 10 is provided with a fan blade 12. The mounting rod 11 is provided with a C-shaped rod 13 that penetrates its side wall. One end of the C-shaped rod 13 is provided with a grinding rod 14. A spring 15 is sleeved on the C-shaped rod 13 between the grinding rod 14 and the mounting rod 11.

[0021] like Figure 2 , 3 As shown, the inner diameter of the opening end of the cover 15 is smaller than the inner diameter of the sleeve 4, and the fan blade 12 is mounted on the output shaft of the motor 10 inside the opening of the cover 15.

[0022] In this embodiment, the mounting rod 11 is provided with a through hole for the through-hole of the C-shaped rod 13. The two ends of the C-shaped rod 13 are connected by a strip plate 16. The strip plate 16 is provided with bolts for locking and fixing the grinding rod 14. The back of the strip plate 16 is provided with a magnetic seat 17 corresponding to the mounting rod 11. A polyethylene insulating cover 18 is fastened to the magnetic seat 17.

[0023] In this embodiment, the top of the sleeve 4 is fitted with a limiting ring 19 located above the cylinder 3. The limiting ring 19 prevents the sleeve 4 from completely sliding into the cylinder 3. The bottom of the sleeve 4 is higher than the horizontal plane of the bottom of the cylinder 3. The cylinder 3 is fixedly connected to the machine base 1.

[0024] like Figure 3 As shown, the locking mechanism 5 includes an electric push rod 51 disposed on the outer wall of the top of the cylinder 3, and a pressing rod 52 disposed on the output shaft of the electric push rod 51. The cylinder 3 and the sleeve 4 are provided with mounting holes for the corresponding pressing rod 52 to pass through.

[0025] When using, select a sleeve 4 of the corresponding size according to the diameter of the filter housing of this batch. At the same time, the sleeve 4 is screwed and fixed to the cylinder 3, and the corresponding mounting holes on the sleeve 4 and the cylinder 3 are aligned. The isolation cover 18 is removed, and the C-shaped rod 13 is pulled and slid in the through hole while the spring 15 is compressed. Finally, the magnetic seat 17 is magnetically connected to the mounting rod 11, and the C-shaped rod 17 is fixed to the grinding rod 14 through the strip plate 16. The gap between the grinding rod 14 and the inner wall of the sleeve 4 can be used to smoothly install the filter housing.

[0026] When inserting the filter housing, open the switch door of the housing 2 and place the housing into the sleeve 4. At this time, the grinding rod 14 is located in the opening of the housing, and the lowered bottom end of the housing contacts the top surface of the cover 6 to provide support. Then, by forcibly pressing, the C-shaped rod 13, the strip plate 16 and the grinding rod 14 are moved to the right, so that the magnetic seat 17 is separated from the mounting rod 11. At the same time, a magnetic isolation cover 18 is fastened on the magnetic seat 17. At this time, bolts can be set on the isolation cover 18 to lock it to the magnetic seat 17, so as to prevent the magnetic attraction of the magnetic seat 17 from acting on the mounting rod 11 to drive the grinding rod 14 to move towards the mounting rod 11 and compress the spring 15.

[0027] During grinding and polishing, the electric push rod 51 drives the extrusion rod 52 to slide within the mounting hole and contact the outer wall of the filter housing inside the sleeve 4, thereby locking and fixing it to prevent the grinding rod 14 from causing the housing to rotate inside the sleeve 4 during grinding. The motor 10 drives the mounting rod 11, the C-shaped rod 13, the strip plate 16, and the grinding rod 14 to rotate inside the filter housing. The grinding rod 14, which contacts the inner wall of the housing, can then perform the grinding and polishing work. During this process, under the influence of the spring 15's extension force, the strip plate 16 is pushed, causing the grinding rod 14 to remain in contact with the inner wall of the housing. This allows the position of the grinding rod 14 to be automatically adjusted slightly under the influence of the spring 15 during rotational grinding, ensuring full contact with the inner wall of the housing. This allows the grinding rod 14 to fully grind the inner wall of the filter housing. During the grinding process, the output shaft of the motor 10 also drives the fan blade 12 to rotate, thereby generating a strong suction force to draw the grinding debris from the housing downwards into the cover 6. Finally, the debris is guided into the dust collector bag through the exhaust pipe 9 for filtration. The filtered gas is discharged through the exhaust pipe on the box. Finally, the dust collector bag can be replaced by opening the switch door on the box.

[0028] After the work is completed, the filter housing can be removed from the sleeve 4 by following the reverse steps. At the same time, the cover 6 can be moved down by the hydraulic rod 7 to fully open the bottom opening of the cylinder 3 and the sleeve 4, so as to facilitate the cleaning or maintenance of the internal components.

[0029] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
