Description

Technical Field

[0001] This utility model belongs to the field of bearing manufacturing, and specifically relates to a burr removal device for the end face of bearing rings. Background Technology

[0002] In the field of mechanical manufacturing, bearing races are key components of bearings, and their surface quality significantly impacts the overall performance and lifespan of the bearing. However, during the machining process of bearing races, burrs often form on their end faces due to various factors. These burrs not only affect the appearance quality of the bearing races but can also adversely affect bearing operation during use, such as increasing friction and wear, and even leading to bearing failure. Therefore, cleaning the burrs from the end faces of bearing races is an essential step in the bearing machining process.

[0003] Currently, most existing methods for deburring the end faces of bearing races involve grinding and cleaning one side first, and then cleaning the other side. This method has significant problems and limitations. First, because each side of the bearing race needs to be clamped and ground separately, the entire cleaning process is time-consuming, resulting in low production efficiency. Second, multiple clamping not only increases the difficulty of operation but also easily introduces errors. During each clamping process, differences in operator skill, equipment precision, and clamping method can cause changes in the position and orientation of the bearing race, thus affecting the final cleaning effect. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a bearing ring end face burr cleaning device to solve the problems of complex operation and low efficiency in the existing bearing ring end face burr cleaning. It can complete the simultaneous cleaning of both end faces of the bearing ring in one clamping, thus improving the efficiency of bearing ring end face burr cleaning.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A bearing race end face burr cleaning device includes a worktable, a drive motor mounted at one end of the worktable, a lead screw connected to the output shaft of the drive motor, the lead screw being rotatably connected to the worktable, a first guide rail provided on the worktable, a first slider slidably mounted on the first guide rail, a lower clamping seat provided on the upper part of the first slider, an upper clamping seat provided on the upper part of the lower clamping seat, the two ends of the lower clamping seat and the upper clamping seat being connected by fastening bolts, and the bearing race being installed between the lower clamping seat and the upper clamping seat; two fixed seats are symmetrically provided on the worktable, and a grinding mechanism is provided on the fixed seats, the grinding mechanism including a motor base, a grinding motor mounted on the motor base, and a grinding wheel connected to the output shaft of the grinding motor, the two grinding wheels being symmetrically arranged on both sides of the lower clamping seat.

[0009] Furthermore, a fixing plate is fixedly connected to both sides of the fixing base, and a positioning plate is provided on the side of the fixing plate near the bearing ring. The positioning plate is connected to the fixing plate through a connecting rod, and one side of the positioning plate is flush with the working surface of the grinding wheel.

[0010] Furthermore, the connecting rod is clearance-fitted with the fixed plate, and an adjusting screw is fixedly connected to the middle of the positioning plate. The adjusting screw is clearance-fitted with the fixed plate, and the adjusting screw is provided with two sets of adjusting nuts, which are located on both sides of the fixed plate.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figure 1 , Figure 2As shown, a bearing race end face burr cleaning device includes a worktable 1. A drive motor 11 is mounted on one end of the worktable 1. A lead screw 12 is connected to the output shaft of the drive motor 11 and is rotatably connected to the worktable 1. A first guide rail 13 is provided on the worktable 1. A first slider 15 is slidably mounted on the first guide rail 13. A lower clamp 14 is provided on the upper part of the first slider 15, and an upper clamp 16 is provided on the upper part of the lower clamp 14. The two ends of the lower clamp 14 and the upper clamp 16 are connected by fastening bolts 17. The bearing race is installed between the lower clamp 14 and the upper clamp 16. Two fixed seats 2 are symmetrically provided on the worktable 1. A grinding mechanism 3 is provided on the fixed seats 2. Figure 3 As shown, the grinding mechanism 3 includes a motor base 31, on which a grinding motor 36 is mounted. A grinding wheel 37 is connected to the output shaft of the grinding motor 36, and the two grinding wheels 37 are symmetrically arranged on both sides of the lower clamp 14.

[0026] like Figure 2 As shown, several V-shaped grooves 18 are evenly arranged on the upper clamp 16 and the lower clamp 14. The bearing ring is placed inside the V-shaped groove 18, which ensures the stability of the bearing ring during grinding.

[0027] like Figure 4 As shown, the fixed base 2 has an adjustment groove 21 in the middle, a second guide rail 22 on the fixed base 2, a second slider 23 slidably mounted on the second guide rail 22, a slide block 32 on the upper part of the second slider 23, and a motor base 31 fixedly mounted on the slide block 32. Figure 5 As shown, the lower part of the slide block 32 is provided with a connecting plate 33, and the connecting plates 33 on both sides are threaded with double-ended studs 34. One end of the double-ended studs 34 is provided with a handwheel 35. By rotating the handwheel 35, the distance between the two slide blocks 32 can be adjusted, which makes it easier to adjust the distance between the two grinding wheels 37 according to the thickness of the bearing ring, thus enhancing the flexibility of the cleaning device.

[0028] like Figure 4 As shown, the fixed base 2 is fixedly connected to both sides of the fixed plate 24. The fixed plate 24 is provided with a positioning plate 25 on the side of the fixed plate 24 near the bearing ring. The positioning plate 25 is connected to the fixed plate 24 through the connecting rod 26, and one side of the positioning plate 25 is flush with the working surface of the grinding wheel 37. The positioning plate 25 is used to position the bearing ring clamped between the upper clamp 16 and the lower clamp 14 during grinding, so that the distance between the two end faces of the bearing ring and the grinding wheels 37 on both sides is equal, thus ensuring the grinding effect of the bearing ring end face.

[0029] like Figure 4As shown, the connecting rod 26 is clearance-fitted with the fixed plate 24, and the positioning plate 25 is fixedly connected to the middle of the adjusting screw 27. The adjusting screw 27 is clearance-fitted with the fixed plate 24, and the adjusting screw 27 is provided with two sets of adjusting nuts 28, which are located on both sides of the fixed plate 24, so as to facilitate the adjustment of the position of the positioning plate 25 according to the thickness of the bearing ring and the wear of the grinding wheel 37.

[0030] like Figure 4 As shown, the positioning plate 25 has folded edges at both ends to prevent the positioning plate 25 from directly impacting the bearing ring during cleaning, thus avoiding damage to the bearing ring or the positioning plate 25.

[0031] When cleaning burrs on the end face of the bearing race, the bearing race is placed on the V-groove 18 on the lower clamp 14, and the upper clamp 16 is fastened to the upper part of the bearing race. Then, the upper clamp 16 and the lower clamp 14 are connected by the fastening bolt 17. During cleaning, the drive motor 11 is started, which drives the lead screw 12 to rotate. The lead screw 12 drives the lower clamp 14 to move on the worktable 1. When the bearing race moves to one side of the positioning plate 25, if the distance of the bearing race extending from both sides of the lower clamp 14 is inconsistent, the bearing race is pushed to the middle of the lower clamp 14 under the interference of the positioning plate 25, so that the distance of the bearing race extending from both sides of the lower clamp 14 is equal. When the lower clamp 14 continues to move, the grinding wheel 37 grinds and polishes the bearing race to remove the burrs on the end face of the bearing race. This realizes the simultaneous cleaning of the two end faces of the bearing race in one clamping, reduces the number of times the bearing race is clamped, and improves the efficiency of cleaning burrs on the end face of the bearing race.

[0032] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
