Description

Technical Field

[0001] The utility model belongs to the technical field of drill polishing processing, in particular to a surface polishing device for alloy gun drill processing. Background Art

[0002] The gun drill polishing device is a device used to perform surface polishing on a gun drill (a deep hole drill).

[0003] During operation, the gun drill is securely fixed to the fixture. Driven by a power system, the polishing head rotates at high speed. Through contact with the drill surface, the polishing material's abrasive action removes minor imperfections and roughness. During the polishing process, the polishing head moves along the drill's axis at a constant feed rate, effectively polishing the entire drill surface.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1 to 2As shown, a surface polishing device for alloy gun drilling according to an embodiment of the present invention includes a machine tool 1; two first supports 11 are fixedly connected to the top of the machine tool 1; a hard water pipe 12 is rotatably connected to the middle of the two first supports 11; a water inlet 13 is connected to the side wall of the hard water pipe 12; two second supports 14 are fixedly connected to the side wall of the hard water pipe 12; a support rod 15 is rotatably connected to the middle of the two second supports 14; a limit seat 16 is fixedly connected to the top of the machine tool 1; the end of the support rod 15 can be fixed in the limit seat 16. A nozzle 17 is fixedly connected to the side wall of the hard water pipe 12; and a plurality of nozzles 18 are fixedly connected to the inner wall of the nozzle 17. During operation, the position of the support rod 15 in the limit seat 16 is changed to drive the hard water pipe 12 to rotate in the first support 11, so that the nozzle 17 can surround gun drills of various sizes at a better angle. At this time, the water inlet 13 is connected to the water pump, and water is sprayed out from the nozzle 18 through the water inlet 13 to cool the drill bit being polished; by setting the nozzle 17 with adjustable angle, the drill bit being polished can be cooled more fully, reducing the problem of material breakage caused by uneven cooling; at the same time, by setting the limit seat 16, the hard water pipe 12 can be fixed in a precise position for continuous operation, thereby improving work efficiency.

[0025] like Figure 2 As shown, the side wall of the rigid water pipe 12 is fixedly connected to an air chamber 2; the top of the air chamber 2 is connected to an air inlet pipe 21; and the side wall of the air chamber 2 is provided with multiple air jet holes 22. During operation, the air inlet pipe 21 is connected to an air pump, which vents air into the air chamber 2 and then exhausts it through the air jet holes 22. The exhausted air serves to guide and focus the water mist sprayed from the nozzle 18. The provision of the air chamber 2 capable of spraying air can guide and focus the water mist discharged from the nozzle 18. At the same time, the air discharged from the air jet holes 22 can blow away debris generated during polishing, reducing the problem of air jet holes 22 being clogged.

[0026] like Figure 2 As shown, a connecting rod is fixed to the side wall of the rigid water pipe, located on the side wall away from the air chamber. A windbreak plate is fixed to the end of the connecting rod. When the air chamber is operating, due to Bernoulli's principle, airborne dust may be blown toward the drill bit by the airflow, affecting polishing accuracy. In this case, the connecting rod prevents some of the dust from entering the work area with the airflow. The windbreak plate reduces dust pollution caused by Bernoulli's principle during operation of the air chamber.

[0027] like Figure 3As shown, the top of the machine tool 1 is provided with a first slide rail 4, which is slidably connected to a first slide rod 41. A transparent sleeve 42 is fixedly connected to the end of the first slide rod 41. During operation, the first slide rod 41 is controlled to slide within the first slide rail 4, driving the transparent sleeve 42 to move to a suitable position to collect debris generated during polishing, thereby reducing clogging caused by debris. The provision of a movable transparent sleeve 42 provides preliminary collection of debris generated during operation, reducing clogging caused by debris.

[0028] like Figure 4 As shown, the top of the machine tool 1 is provided with a second slide rail 5; a second slide bar 51 is slidably connected to the second slide rail 5; a motor 52 is fixedly connected to the top of the second slide bar 51; a rotating shaft 53 is rotatably connected to the side wall of the motor 52; a polishing disk 54 is rotatably connected to the rotating shaft 53; the polishing disk 54 is replaceable and removable; the second slide rail 5 is slidably connected to a third slide bar 56; a third slide rail 57 is provided on the side wall of the third slide bar 56; a fourth slide bar 58 is slidably connected to the third slide bar 57; a drill bit holder is fixedly connected to the top of the fourth slide bar 58. 659; an elastic cloth 55 is fixedly connected between the second slide bar 51 and the third slide bar 56. During operation, the required polishing drill bit is placed in the drill bit holder. 659, the third slide bar 56 is controlled to slide to the appropriate position within the second slide rail 5, and the fourth slide bar 58 is controlled to slide to the appropriate height within the third slide rail 57; the motor 52 is turned on, so that the rotating shaft 53 drives the elastic cloth 55 to rotate, and the second slide bar 51 is controlled to slide to the appropriate position within the second slide rail 5 to polish the drill bit. At this time, the elastic cloth 55 moves with the second slide bar 51 and the third slide bar 56, blocking the debris and wastewater generated during operation and preventing them from entering the second slide rail 5; by providing the elastic cloth 55 that moves with the second slide bar 51 and the third slide bar 56, the debris and wastewater generated during operation are further processed and prevented from entering the second slide rail 5, thereby reducing the problem of the second slide rail 5 being blocked by debris; at the same time, the provision of the elastic cloth 55 also facilitates the subsequent disposal of debris.

[0029] like Figure 5 As shown, two third supports 6 are fixedly attached to the sidewalls of the machine tool 1; a collection bin 61 is rotatably connected between the two third supports 6. During operation, debris and wastewater collected by the elastic cloth 55 and the transparent sleeve 42 are collected in the collection bin 61. The provision of the collection bin 61 collects debris and wastewater generated during operation, reducing clutter on the work platform caused by excessive debris accumulation and facilitating cleanup at the end of the operation.

[0030] Working principle: During operation, the position of the support rod 15 in the limit seat 16 is changed, driving the hard water pipe 12 to rotate in the first support 11, so that the nozzle 17 can surround gun drills of various sizes at a better angle. At this time, the water inlet 13 is connected to the water pump, and water is sprayed out from the nozzle 18 through the water inlet 13 to cool the drill bit being polished. During operation, the air inlet pipe 21 is connected to the air pump to ventilate the interior of the air filling chamber 2, and then discharged from the air jet hole 22. The discharged gas plays a certain guiding and focusing role on the water mist sprayed from the nozzle 18. When the air filling chamber 2 is working, due to the Bernoulli principle, dust floating in the air may be blown toward the drill bit with the air flow, affecting the polishing accuracy. At this time, the wind resistance plate 31 is set to prevent some dust from entering the working area with the air flow. During operation, the first slide bar 41 is controlled to slide in the first slide rail 4, driving the transparent sleeve 42 to move to the appropriate position to collect the debris generated during the polishing work, reducing the blockage problem caused by debris. During operation, the desired polishing drill bit is placed in the drill bit holder. Inside the drill bit holder 659, the third slide bar 56 is controlled to slide to the appropriate position within the second slide rail 5, and the fourth slide bar 58 is controlled to slide to the appropriate height within the third slide rail 57. The motor 52 is turned on, causing the rotating shaft 53 to rotate the elastic cloth 55. The second slide bar 51 is then controlled to slide to the appropriate position within the second slide rail 5 to polish the drill bit. At this point, the elastic cloth 55 moves along with the second and third slide bars 51, 56, blocking debris and wastewater generated during operation and preventing them from entering the second slide rail 5. During operation, the debris and wastewater collected by the elastic cloth 55 and the transparent sleeve 42 are collected in the collection bin 61.
