[0021] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] like Figures 1 to 4 As shown, the filter element frame chamfering and cutting device 100 of the present invention includes a base 1 , a blade 2 fixed on the base 1 , and a blade holder 3 .

[0025] The base 1 is cylindrical in shape as a whole, and the bottom is used to be placed on the ground or a workbench.

[0026] The base 1 is hollow and has an inclined surface 11 sloping from top to bottom. The tool holder 3 and the blade 2 are both fixed on the inclined surface 11 .

[0027] In this embodiment, the base 1 is in the shape of a column with a small top and a large bottom, and the inclined surface 11 is inclined downward from the top.

[0028] The inclined surface 11 is provided with a cutting groove 12, which penetrates the base 1 and gradually widens from top to bottom. The blade 21 of the blade 2 partially protrudes into the cutting groove 12. When the filter element frame needs to be cut, the filter element frame is horizontally inserted into the cutting groove 12, moved upward until it contacts the blade 21, and then the filter element frame is rotated to complete the chamfering process.

[0029] The blade holder 3 and the blade 2 are mounted on the inclined surface 11 of the base 1 . In this embodiment, the blade 2 is fixed on the blade holder 3 , and the blade holder 3 is fixed on the inclined surface 11 .

[0030] In this embodiment, there are two tool holders 3 , which are arranged at intervals up and down along one side of the cutting groove 12 .

[0031] The cutting edge 21 of the blade 2 gradually protrudes into the cutting groove 12 from bottom to top along the edge of the cutting groove 12 .

[0032] Specifically, the blade holder 3 is provided with a fixing slot 31, which has an opening facing a side away from the cutting slot 12. The blade holder 3 is fixed to the base 1 via a bolt 33 passing through the fixing slot 31. In this embodiment, the relative position of the bolt 33 and the fixing slot 31 can be adjusted to adjust the position and angle of the blade 2 relative to the cutting slot 12, thereby controlling the position and width of the blade 21 protruding into the cutting slot 12.

[0033] The blade 2 is fixed to the blade holder 3 on a side close to the cutting groove 12. The blade holder 3 is provided with a support block 32 extending toward the inclined surface 11. The blade 2 is supported against the support block 32 along the extending direction of the inclined surface 11. The support block 32 is used to support the blade 2 to prevent the blade 2 from deflecting when cutting the filter element frame.

[0034] When the filter element frame chamfering and cutting device 100 is assembled, the two tool holders 3 are fixed to the base 1 by bolts 33, the blade 2 is inserted into the tool holder 3, and after adjusting the position, the blade 2 is fixed under the tool holder 3 by screws 34. The filter element frame to be chamfered is extended from the side into the cutting groove 12, and the filter element frame is positioned according to the cone angle of the cutting groove 12. The filter element frame is rotated, and the contact part of the filter element frame and the art blade 2 is cut off. The rotation is stopped until the chamfer of the filter element frame reaches the target value, and the filter element frame is taken out to complete the chamfering.

[0035] The tool holder 3 and the base 1 are made of stainless steel.

[0036] The blade 2 is made of ceramic material, which can effectively prevent iron and other forms of metal elements from escaping and contaminating the skeleton. The ceramic blade 2 as a cutting component can effectively prevent the cutting surface from being contaminated. In addition, the ceramic blade 2 is highly sharp and can remove excess parts of the skeleton without the need for high-speed rotation cutting, thereby avoiding the introduction of cutting fluid to cause greater pollution.

[0037] The filter element frame chamfering and cutting device 100 of the present invention is small and flexible, and can be placed at the filter element production site, so as to facilitate the adjustment of the filter element frame external dimensions during the production process. There is no need to introduce a power source, and there is no emission, and no waste liquid is generated, which is convenient for daily production and maintenance. Compared with manual chamfering, it can not only ensure the external dimensions of the filter element frame but also avoid injuries to operators.

[0038] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
