[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] In one embodiment, such as Figures 1-5 As shown, a general-purpose parts processing burr removal device includes a machine base 1, a support leg 2, and a processing component 3. The processing component 3 includes a fixed shell 32, a first motor 31, and a bidirectional screw 33. The bidirectional screw 33 has reverse threads at both ends, each engaging a driven ring 34. The driven ring 34 is connected to a fixed ring 36 via a connecting rod 35. The fixed ring 36 fixes a driven rod 38. The top end of the driven rod 38 is rotatably connected to a bearing of the fixed shell 32 via a limiting shaft 37. The bottom end of the driven rod 38 is connected to a grinder 39. When the first motor 31 drives the bidirectional screw 33 to rotate, the two driven rings 34 move synchronously in opposite directions, driving the grinder 39 to rise and fall.

[0034] In this embodiment, the thread lead of the bidirectional screw 33 is 5mm, the power of the first motor 31 is 750W, and the adjustable lifting speed range is 0.1-1mm / s. By driving the first motor 31, the bidirectional screw 33 is rotated. When the bidirectional screw 33 rotates, it will drive the two sets of driven rings 34 to move in opposite directions, and at the same time drive the driven rods 38 to move in opposite directions, so that the grinder 39 moves to the position to be ground and grinds the parts. The support foot 2 is adjustablely connected to the bottom of the machine base 1 through anchor bolts for horizontal calibration.

[0035] In one embodiment, such as Figure 2 As shown, the driven ring 34, connecting rod 35, fixed ring 36, limiting shaft 37, driven rod 38, and grinder 39 are all axially arranged along the symmetrical center line of the two sets of threads of the bidirectional screw 33. When the bidirectional screw 33 is rotated by the first motor 31, the two sets of grinders 39 move in opposite directions to simultaneously grind and deburr the upper and lower surfaces of the gear 46, thereby increasing the working efficiency of deburring.

[0036] In one embodiment, such as Figure 3As shown, the grinder 39 consists of a grinding head 391, an abrasive ball 392, a nylon brush 393, and a rubber pad 394. The top of the grinding head 391 is fixedly connected to the abrasive ball 392, and the abrasive ball 392 is installed on the outer ring of the top of the grinding head 391. The center of the top of the grinding head 391 is fixedly connected to the bottom of the rubber pad 394. One end of the nylon brush 393 is fixedly connected to the outer wall of the rubber pad 394. A cleaning assembly 4 is also provided on the top of the machine base 1. When the grinding head 391 contacts the surface of the gear 46, the abrasive ball 392 on the surface of the grinding head 391 will abrade the surface of the gear 46 to increase the abrasive treatment effect. As the grinding heads 391 move relative to each other, the two sets of rubber pads 394 come into contact with and press against each other. When deburring the thinner gear 46, the two sets of grinding heads 391 are closer together, and the rubber pads 394 are pressed more deeply. The closer the nylon brushes 393 on both sides of the rubber pads 394 are to the meshing surface of the gear 46, the denser the nylon brushes 393 are, and the smaller the brushing area. When deburring the thicker gear 46, the two sets of grinding heads 391 are farther apart, the rubber pads 394 are pressed less, and the farther the nylon brushes 393 on both sides of the rubber pads 394 are from the meshing surface of the gear 46, the sparser the nylon brushes 393 are, and the larger the brushing area is.

[0037] In one embodiment, such as Figure 4 As shown, the cleaning assembly 4 includes a support shell 41 fixedly installed on the top of the machine base 1, a support plate 42 fixedly installed on the top of the support shell 41, a drive cylinder 43 fixedly installed on the top of the support plate 42, and a limiting head 44 fixedly installed on the output end of the drive cylinder 43. A second motor 45 is fixedly installed inside the support shell 41, and a gear 46 is inserted into the output shaft of the second motor 45. A water spray pipe 47 is fixedly installed on the inner wall of the support plate 42, and a blower 48 is fixedly installed on the inner wall of the support plate 42 away from the water spray pipe 47. A recycling assembly 5 is provided on the side of the machine base 1 away from the blower 48. The cleaning assembly 4 is activated by starting the drive cylinder 43. The limiting head 44 is driven to contact the top of the gear 46, limiting the protruding part of the center of the gear 46 to prevent the gear 46 from deviating from the original preset trajectory when rotating. Then, the second motor 45 is started to drive the gear 46 to rotate, so that the two sets of grinding heads 391 automatically contact the upper and lower surfaces of the gear 46 to deburr the surface of the gear 46. While the gear 46 is being ground, water is sprayed through the water spray pipe 47 to reduce the temperature generated by the contact between the gear 46 and the grinding head 391. Then, the blower 48 blows air at the water spray position, so that the water flow and air come into contact with each other to form a water curtain and an air curtain, blocking the splashing burrs and preventing harm to the workers.

[0038] In one embodiment, such as Figure 4As shown, the center position of the output shaft of the second motor 45 coincides with the center position of the output end of the drive cylinder 43, so that the gear 46 always stays on the same axis when rotating, which makes it easier for the grinding head 391 to grind the gear 46.

[0039] In one embodiment, such as Figure 4 As shown, the bottom of the water spray pipe 47 is connected to a water storage device, and the water storage device is equipped with a water pump to continuously provide water to the water spray pipe 47 and power for spraying.

[0040] In one embodiment, such as Figure 5 As shown, the recycling component 5 consists of a baffle 51, a filter plate 52, a collection box 53, and a handle 54. The bottom of the baffle 51 is fixedly connected to the top of the filter plate 52, the bottom of the filter plate 52 is slidably connected to the top of the collection box 53, and one side of the collection box 53 is fixedly connected to one side of the handle 54. When the blower 48 disperses the water flow from the spray pipe 47, the burrs polished off the surface of the gear 46 are also blown onto the surface of the baffle 51 by the air and water, and slowly slide down the surface of the baffle 51. At the same time, the burrs are separated by the filter plate 52 and fall onto the surface of the filter plate 52. The water flow is collected by the collection box 53, and the water flow can be recycled at any time by pulling the handle 54, thereby improving the efficiency of water resource recycling.

[0041] In one embodiment, such as Figure 2 As shown, the limiting head 44 is made of polyurethane material. The elastic modulus of polyurethane is adjustable (Shore hardness A 60-95), which can effectively absorb the impact vibration in the transmission of gear 46, reduce noise, and compared with metal limiting head 44, the soft contact characteristics of polyurethane can prevent scratches on the surface of gear 46 and extend the life of gear 46.

[0042] The above embodiments disclose a general-purpose burr removal device for parts processing. When the first motor 31 drives the bidirectional screw 33 to rotate, the two driven rings 34 move synchronously in opposite directions, driving the grinder 39 to rise and fall, so that the grinder 39 moves to the position to be ground and grinds the parts. The rubber pads 394 between the two sets of grinding heads 391 squeeze each other, automatically adjusting the actual brushing density of the nylon brush 393 on the meshing surface of the gear 46, which can remove burrs from gears 46 of different thicknesses. At the same time, the blower 48 blows air to the water spray position, so that the water flow and the air come into contact with each other to form a water curtain and an air curtain, blocking the splashing burrs and reducing the harm to the environment and workers.

[0043] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
