The plurality of openings are respectively located on the inner sides of the plurality of needle rollers and are connected to the interior of the collection chamber.

[0007] By adopting the above technical solution, when the needle roller moves, the residue generated by the friction with the core shaft and the needle roller tube rack will enter the collection chamber from the opening, and then be firmly adsorbed by the magnetic disk, effectively preventing the residue from flowing back and causing repeated damage to the core shaft, needle roller tube rack and needle roller, thereby ensuring the accuracy and service life of this product.

[0008] In a preferred example, the present invention can be further configured as follows: a plurality of needle rollers are arranged in a ring shape with equal spacing.

[0009] In a preferred example, the present invention can be further configured as follows: a pressure cover is slidably installed inside the collection chamber, the pressure cover is attached to the outside of the magnet disk, and the sum of the thickness of the magnet disk and the pressure cover is equal to the depth of the collection chamber.

[0010] In a preferred example, the present invention can be further configured as follows: the inner wall of the collection chamber is integrally formed with two plastic sheets, the two plastic sheets are transversely symmetrical about the horizontal center plane of the core axis, and the plastic sheets are movably engaged with the pressure cover.

[0011] In a preferred example, the present invention can be further configured as follows: a plurality of protrusions are evenly spaced and annularly surrounded on the outside of the magnet disk and the outside of the pressure cover, and a plurality of sliding grooves suitable for the sliding of the protrusions are opened on the inner wall of the collection chamber.

[0012] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0013] In the utility model, when the needle roller moves, the residue generated by the friction with the core shaft and the needle roller tube rack will enter the collection chamber from the opening and then be firmly adsorbed by the magnetic disk, effectively preventing the residue from flowing back and causing repeated damage to the core shaft, the needle roller tube rack and the needle roller, thereby ensuring the accuracy and service life of this product.

[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0026] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0027] A high-precision bearing position machining rolling cutter provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0028] Example 1:

[0029] Combine Figure 1-5 As shown, the utility model provides a high-precision bearing position machining rolling cutter, including a tool mechanism 100 and a slag removal mechanism 200. The tool mechanism 100 includes a core shaft 110, a needle roller tube frame 120 sleeved on the outside of the core shaft 110, and a plurality of needle rollers 130 movably embedded in one end of the needle roller tube frame 120.

[0030] The slag removal mechanism 200 includes a collection chamber 210 opened at one end of the core shaft 110, a plurality of openings 220 opened on the outer wall of the core shaft 110, and a magnet disk 230 movably installed inside the collection chamber 210. The plurality of openings 220 are respectively located on the inner sides of the plurality of rollers 130 and are connected to the interior of the collection chamber 210.

[0031] Furthermore, the plurality of needle rollers 130 are arranged in a ring shape at equal intervals. This layout design ensures the aesthetics of the product.

[0032] Furthermore, a plurality of protrusions 500 are evenly spaced and arranged in a circular shape on the outside of the magnet disk 230 and the outside of the pressure cover 300. The inner wall of the collection chamber 210 is provided with a plurality of sliding grooves suitable for the sliding of the protrusions 500. The protrusions 500 cooperate with the sliding grooves to ensure the stable installation of the magnet disk 230 and the pressure cover 300.

[0033] Example 2:

[0034] Combine Figure 1 、 3 and Figure 5 As shown, based on the first embodiment, a pressure cover 300 is slidably installed inside the collection chamber 210, and the pressure cover 300 is attached to the outside of the magnet disk 230. The sum of the thickness of the magnet disk 230 and the pressure cover 300 is equal to the depth of the collection chamber 210. The pressure cover 300 is provided to limit the magnet disk 230.

[0035] Example 3:

[0036] Combine Figure 1-5 As shown, in the above embodiment, two plastic sheets 400 are integrally formed on the inner wall of the collecting chamber 210, and the two plastic sheets 400 are laterally symmetrical about the horizontal center plane of the core shaft 110. The plastic sheets 400 are movably engaged with the pressure cover 300. The provision of the plastic sheet 400 can limit the pressure cover 300 and prevent the pressure cover 300 from separating from the core shaft 110 on its own.

[0037] The working principle and usage process of the present invention: When the device is put into actual use, when the needle roller 130 moves, the residue generated by the friction with the core shaft 110 and the needle roller tube rack 120 will enter the collection chamber 210 from the opening 220, and then be firmly adsorbed by the magnetic disk 230, effectively preventing the residue from flowing back and causing repeated damage to the core shaft 110, the needle roller tube rack 120, and the needle roller 130, thereby ensuring the accuracy and service life of this product.

[0038] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
