Description

Technical Field

[0001] This utility model relates to the field of reamer processing, specifically a cleaning device for reamer processing. Background Technology

[0002] A cleaning device for reamers is a device used to clean reamers after machining, with the main purpose of reducing residue on the reamer surface after machining.

[0003] Patent CN213001364U discloses a cleaning device for reamer processing, addressing the shortcomings of existing technologies such as low efficiency and incomplete cleaning. The device includes a base and a synchronous transmission mechanism. The top of the base is sequentially bolted to a column, a support base, a mounting plate, and a fixed base. The top of the column is bolted to a top plate. Through the arrangement of a motor, crank, connecting rod, piston rod, brush, synchronous transmission mechanism, driven bevel gear, and driving bevel gear, efficient and thorough cleaning after reamer processing is crucial for maintaining reamer performance and ensuring subsequent machining accuracy. Currently, some reamer cleaning devices use vertically downward brushes for cleaning. However, this method has revealed many problems in practical applications, especially in cleaning the reamer's chip groove, where it is difficult to achieve ideal results.

[0004] Reamers, as high-precision hole-machining tools, typically feature helical chip flutes designed to ensure smooth chip removal during machining, preventing chip buildup that could affect machining quality and tool life. However, when cleaning the chip flutes of a reamer with a vertically downward-moving brush, there is a significant mismatch between the brush's movement direction and the helical shape of the flutes. Because the brush moves vertically downwards, it cannot closely conform to the inner contour of the helical chip flutes, making it difficult for the brush to reach all parts of the flutes during cleaning.

[0005] Specifically, vertical brushes often cannot reach the spiral corners and depths of the chip retrieval groove. Large amounts of chips, oil, and impurities generated during machining easily accumulate in these areas. Chips that remain in the chip retrieval groove for extended periods not only affect the smoothness of chip removal during subsequent uses but may also scratch the surface of machined holes during later machining, reducing machining accuracy and surface quality. Residual oil can cause the reamer to rust, shortening its lifespan.

[0006] Existing cleaning devices using vertical brushes, even with increased brush pressure or extended cleaning time, cannot fundamentally solve the problem of poor contact between the brush and the chip removal groove. This not only leads to low cleaning efficiency, requiring repeated cleaning to barely achieve a certain level of cleanliness, but also, for some high-precision reamers, this incomplete cleaning method is very likely to cause tool failure, increasing production costs. Utility Model Content

[0007] The purpose of this invention is to provide a cleaning device for reamer processing. By using this device, the problem of poor contact between the brush and the chip removal groove cannot be fundamentally solved by existing cleaning devices that use vertical brushes, even if the brush pressure is increased or the cleaning time is extended.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a cleaning device for reamer processing, comprising a cleaning cylinder, a discharge port disposed on one side of the cleaning cylinder, a first support plate fixedly connected to the top of the cleaning cylinder, a first cylinder fixedly connected to one side of the first support plate, a first air rod fixedly connected to the output end of the first air rod, a connecting plate fixedly connected to the lower end of the first air rod, a clamp disposed below the connecting plate, a pushing mechanism disposed below the connecting plate, and a reciprocating mechanism disposed inside the pushing mechanism;

A support rod is provided inside the third hole. A first guide groove is provided inside the support rod. A first guide rod fixedly connected to the first gear is provided inside the first guide groove. A second gear is meshed with the outer side of the first gear. A rotating cylinder is fixedly connected to the upper end of the second gear. A brush cylinder is fixedly connected to the inner side of the second gear.

[0010] Preferably, the first guide groove has a spiral shape, and the first guide groove and the first guide rod are fitted with a clearance fit.

[0011] Preferably, the sum of the vertical height of the second gear and the vertical height of the rotating cylinder is less than the vertical height of the second hole.

[0012] Preferably, the inner side of the third hole fits against the outer side of the support rod, the support rod has a cylindrical shape, and the central axis of the support rod is parallel to the central axis of the second gas rod.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 The present invention provides a technical solution: a cleaning device for reamer processing, comprising a cleaning cylinder 1, a discharge port 2 disposed on one side of the cleaning cylinder 1, a first support plate 3 fixedly connected to the top of the cleaning cylinder 1, a first cylinder 4 fixedly connected to one side of the first support plate 3, a first air rod 5 fixedly connected to the output end of the first air rod 4, a connecting plate 6 fixedly connected to the lower end of the first air rod 5, a clamp 7 disposed below the connecting plate 6, a pushing mechanism 8 disposed below the connecting plate 6, and a reciprocating mechanism 9 disposed inside the pushing mechanism 8;

[0025] The pushing mechanism 8 includes a second cylinder 801 fixedly connected to the other side above the first support plate 3. A second air rod 802 is fixedly connected to the output end of the second cylinder 801. A first hole 803 for nesting the second air rod 802 is provided inside the connecting plate 6. A filter screen frame 804 is fixedly connected to the lower end of the second air rod 802. A filter screen body 805 is provided inside one side of the filter screen frame 804, and a second hole 806 is provided inside the other side of the filter screen frame 804. A first gear 807 is rotatably connected inside the second hole 806. A third hole 808 is provided inside the first gear 807. A support rod 809 is provided inside the third hole 808. A first guide groove 810 is provided inside the support rod 809, and a part fixedly connected to the first gear 807 is provided inside the first guide groove 810. The first guide rod 811 and the first guide groove 810 have a spiral shape. The first guide groove 810 and the first guide rod 811 are fitted with a clearance fit, so that the first guide rod 811 can rotate when it moves inside the first guide groove 810. The outer side of the first gear 807 is meshed with the second gear 812. The upper end of the second gear 812 is fixedly connected to the rotating cylinder 813. The inner side of the second gear 812 is fixedly connected to the brush cylinder 814. The sum of the vertical height of the second gear 812 and the vertical height of the rotating cylinder 813 is less than the vertical height of the second hole 806. The inner side of the third hole 808 is in contact with the outer side of the support rod 809. The support rod 809 has a cylindrical shape. The central axis of the support rod 809 is parallel to the central axis of the second air rod 802.

[0026] The reciprocating mechanism 9 includes a second guide rod 901 fixedly connected to the outside of the rotating cylinder 813. A fourth hole 902 is connected to one side of the second hole 806. A second guide groove 903 is provided inside the fourth hole 902. The second guide rod 901 is nested inside the second guide groove 903. The upper and lower ends of the fourth hole 902 are connected to a fifth hole 904. An electromagnet 905 is fixedly connected to the lower inner surface of the cleaning cylinder 1. A power supply 906 is fixedly connected to the lower outer surface of the cleaning cylinder 1. The support rod 809 is fixedly connected to the electromagnet 905. The second guide groove 903 is composed of multiple guide grooves with a "V" shape, which allows the second guide rod 901 to move up and down when it moves inside the second guide groove 903. The inner side of the fourth hole 902 is in contact with the outer side of the brush cylinder 814.

[0027] When the reamer needs cleaning, the clamp 7 is used to hold the reamer. The first cylinder 4, the first air rod 5, the connecting plate 6, and the clamp 7 are activated, and the reamer moves downward into the cleaning cylinder 1. The second air rod 802 is activated, driving the second air rod 802 and the filter screen frame 804 to move downward, causing the first gear 807 and the first guide rod 811 to move downward. Because the first guide groove 810 has a spiral shape and the first guide groove 810 and the first guide rod 811 are in a clearance fit, the first gear 807 rotates. This, in turn, drives the second guide rod 901 to rotate, causing the second gear 812, rotating cylinder 813, and brush cylinder 814 to rotate. Ultimately, the brush cylinder 814 moves downward and rotates, allowing it to move along the threaded groove of the reamer. The spirally rotating brush cylinder 814 can better conform to the shape of the chip removal groove. During the rotation, the bristles can penetrate deep into the groove along the spiral direction of the chip removal groove, making full contact with the inner wall of the groove, thereby more effectively removing chips, oil stains, and other impurities from the groove, resulting in a better cleaning effect.

[0028] When the rotating cylinder 813 rotates, it drives the second guide rod 901 to rotate. Since the second guide groove 903 is composed of multiple guide grooves with a "V" shape, the inner side of the fourth hole 902 is in contact with the outer side of the brush cylinder 814, so that the second guide rod 901 moves up and down along the trajectory of the second guide groove 903, driving the rotating cylinder 813 and the brush cylinder 814 to move up and down, so that the chips stuck between the brushes can be freed from the brushes' restraint, reducing the damage to the reamer caused by the chips being driven by the brushes.

[0029] When the filter screen frame 804 moves downward, it drives the filter screen body 805 to move downward, so that the filter screen frame 804 and the filter screen body 805 push the chips downward, so that the chips can get closer to the electromagnet 905, thus fixing the chips and reducing the damage to the reamer caused by the movement of the chips.
