Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to an external surface processing device for bearings. Background Technology

[0002] Bearings are an important component in modern machinery. Their main function is to support rotating mechanical parts and reduce the coefficient of friction of mechanical loads during transmission. The outer ring of a cut bearing has many burrs and unevenness on its edge. To ensure the bearing's aesthetics and suitability for installation, its outer surface needs to be ground. However, traditional bearing surface processing equipment has many drawbacks in its design of the grinding brush. First, most equipment uses a fixed installation method for the grinding brush, which is extremely difficult to disassemble once installed. This makes the operation very cumbersome and time-consuming when the grinding brush wears out or needs to be replaced, or when different types of grinding brushes need to be changed according to different bearing processing techniques and requirements. Therefore, we have introduced a bearing surface processing equipment. Utility Model Content

[0003] The main purpose of this utility model is to provide an external surface processing device for bearings, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A bearing machining surface treatment device includes a base with a fixed frame at the upper rear. A motor is fixedly mounted inside the base via an internal cavity. A drive gear is fixedly mounted on the output end of the motor via a rotating rod. A driven gear is meshed with the outer surface of the drive gear. A driving rod is inserted and fixedly mounted on the upper end of the driven gear. A rotating table is fixedly mounted on the upper end of the driving rod. A support rod is provided at the middle of the upper end of the rotating table. A placement platform is rotatably mounted on the upper surface of the support rod. An installation platform is fixedly mounted on the upper surface of the support rod. Three sliding grooves are provided at the upper end of the installation platform. Three vertical plates are provided at the upper end of the installation platform, arranged in an equidistant circular array. First telescopic cylinders are inserted and fixedly mounted on the outer surfaces of each of the three vertical plates. Clamping mechanisms are provided at the output ends of each of the three first telescopic cylinders. A pressing mechanism is inserted and fixedly mounted on the upper front of the fixed frame.

[0006] Preferably, the clamping mechanism includes a mounting base, the upper end of which is provided with a positioning groove. The inner front wall and inner rear wall of the positioning groove are both provided with fixing holes. A positioning seat is movably engaged inside the positioning groove. Springs are fixedly installed on the inner front and inner rear of the positioning seat through an inner groove. Movable blocks are fixedly installed on the opposite surfaces of the two springs. A locking block is fixedly installed on the end of the two movable blocks away from the springs. A support column is fixedly installed in the middle of the upper end of the positioning seat. A grinding brush is fixedly installed on the end of the support column near the clamping mechanism.

[0007] Preferably, the mounting base is fixedly connected to the output end of the first telescopic cylinder.

[0008] By adopting the above technical solution, the first telescopic cylinder can easily move the mounting block.

[0009] Preferably, the mounting base is slidably mounted inside the slide groove via a slider.

[0010] By adopting the above technical solution, the mounting base can be moved along the direction of the slide groove by the slider.

[0011] Preferably, the clamping mechanism is positioned vertically relative to the placement platform.

[0012] By adopting the above technical solution, the object on the placement platform can be easily pressed and fixed by the clamping mechanism.

[0013] Preferably, the clamping mechanism includes a second telescopic cylinder, the output end of which is fixedly fitted with an internal threaded sleeve, the inner surface of which is threadedly connected to a threaded rod, and the lower end of which is provided with a clamping plate.

[0014] By adopting the above technical solution, the second telescopic cylinder can easily drive the pressure plate to move up and down, thereby facilitating height adjustment.

[0015] Preferably, the clamping plate is detachably connected to the internal threaded sleeve via a threaded rod.

[0016] By adopting the above technical solution, the pressure plate can be easily disassembled and replaced via the threaded rod.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this utility model, the positions of the three grinding brushes can be easily adjusted according to the size of the bearing by three first telescopic cylinders, which facilitates grinding of bearings of different sizes. By simultaneously squeezing the two locking blocks, the internal springs are compressed and the two locking blocks are disengaged from the two fixing holes, which facilitates quick disassembly. During installation, the locking blocks are squeezed by the inner wall of the positioning groove, compressing the spring and causing the locking blocks to retract into the positioning seat. When the positioning seat moves to the appropriate position and the locking blocks are aligned with the fixing holes, the spring releases its elastic potential energy, pushing the moving block outward, so that the locking blocks are inserted into the fixing holes for fixation. This facilitates quick replacement of the grinding brushes and helps maintain a good grinding effect.

[0019] 2. In this utility model, when it is necessary to fix bearings of different sizes, the threaded rod on the pressure plate is disassembled and separated from the inner threaded sleeve by rotating the pressure plate. During installation, the threaded rod and the inner threaded sleeve are connected together by thread, which can achieve quick replacement and installation. Attached Figure Description

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] The bearing machining outer surface equipment includes a base 1, a fixed frame 2 at the upper rear of the base 1, a motor 3 fixedly installed inside the base 1 through an inner cavity, a drive gear 4 fixedly installed at the output end of the motor 3 through a rotating rod, a driven gear 5 meshing with the outer surface of the drive gear 4, a driving rod 6 fixedly installed at the upper end of the driven gear 5, a rotating table 7 fixedly installed at the upper end of the driving rod 6, a support rod 8 at the upper middle of the rotating table 7, a placement platform 9 rotatably installed on the upper surface of the support rod 8, a mounting platform 10 fixedly installed on the upper surface of the support rod 8, three sliding grooves 11 at the upper end of the mounting platform 10, three vertical plates 12 at the upper end of the mounting platform 10, the three vertical plates 12 being distributed in a equidistant circular array, a first telescopic cylinder 13 fixedly installed on the outer surface of each of the three vertical plates 12, a clamping mechanism 14 at the output end of each of the three first telescopic cylinders 13, and a pressing mechanism 15 fixedly installed at the upper front of the fixed frame 2.

[0030] In this embodiment, the clamping mechanism 14 includes a mounting base 140. The upper end of the mounting base 140 is provided with a positioning groove 141. The inner front wall and inner rear wall of the positioning groove 141 are both provided with fixing holes 142. The positioning base 143 is movably engaged inside the positioning groove 141. The inner front and inner rear of the positioning base 143 are both fixedly installed with springs 144 through inner grooves. The opposing surfaces of the two springs 144 are both fixedly installed with moving blocks 145. The ends of the two moving blocks 145 away from the springs 144 are both fixedly installed with locking blocks 146. The upper middle part of the positioning base 143 is fixedly installed with a support column 147. The end of the support column 147 near the pressing mechanism 15 is fixedly installed with a polishing brush 148. The mounting base 140 is fixedly connected to the output end of the first telescopic cylinder 13. The mounting base 140 is slidably installed inside the slide groove 11 by a slider.

[0031] Through the above scheme: During installation, by inserting the positioning seat 143 into the positioning groove 141, the locking block 146 is squeezed by the inner wall of the positioning groove 141, compressing the spring 144, causing the locking block 146 to retract into the positioning seat 143. When the positioning seat 143 moves to the appropriate position and the locking block 146 aligns with the fixing hole 142, the spring 144 releases its elastic potential energy, pushing the moving block 145 outward, thereby allowing the locking block 146 to be inserted into the fixing hole 142 for fixation. When it is necessary to disassemble the positioning seat 143, only a certain external force needs to be applied to make the locking block 146 compress the spring 144 again and retract into the positioning seat 143, so that the positioning seat 143 can be removed. This achieves quick installation and disassembly of the grinding brush 148, facilitates the disassembly and replacement of worn grinding brush 148, and also facilitates the replacement of the grinding brush 148 material as needed. The controller opens the first telescopic cylinder 13, which facilitates the displacement of the mounting seat 140, making it convenient to adjust according to the diameter of the bearing being ground.

[0032] In this embodiment, the clamping mechanism 15 is vertically aligned with the placement platform 9. The clamping mechanism 15 includes a second telescopic cylinder 150. An internal threaded sleeve 151 is fixedly installed at the output end of the second telescopic cylinder 150. A threaded rod 152 is threadedly connected to the inner surface of the internal threaded sleeve 151. A clamping plate 153 is provided at the lower end of the threaded rod 152. The clamping plate 153 is detachably connected to the internal threaded sleeve 151 through the threaded rod 152.

[0033] With the above scheme: when the second telescopic cylinder 150 is started, it can easily drive the clamping plate 153 to move up and down, thereby facilitating the clamping and fixing of the bearing on the placement platform 9. When it is necessary to fix bearings of different sizes, by rotating the clamping plate 153, the threaded rod 152 on the clamping plate 153 can be disassembled and separated from the inner threaded sleeve 151. During installation, by threading the threaded rod 152 and the inner threaded sleeve 151 together, quick replacement and installation can be achieved.

[0034] It should be noted that this utility model is an outer surface processing device for bearings. During use, the bearing whose outer surface needs grinding is first placed on the placement table 9. The controller opens the second telescopic cylinder 150, facilitating the downward movement of the clamping plate 153 until it presses and fixes the bearing. During grinding, the controller opens the three first telescopic cylinders 13, which respectively drive the three grinding brushes 148 towards the outer surface of the bearing until they are in contact with it. The controller then opens the motor 3, which drives the drive gear 4 to rotate via a rotating rod. The drive gear 4 drives the driven gear 5 to rotate, which in turn drives the mounting table 10 to rotate. The rotation of the mounting table 10 facilitates the rotation of the three grinding brushes 148 above, allowing the three grinding brushes 148 to grind the outer surface of the bearing. The cylinder 13 is easily adjustable according to the bearing size, facilitating the grinding of bearings of different sizes. When the grinding brush 148 wears out after prolonged use, the two locking blocks 146 are simultaneously squeezed, causing the internal spring 144 to contract due to the compression. This disengages the two locking blocks 146 from the two fixing holes 142, allowing for quick and easy disassembly. During installation, the seat 143 is inserted into the positioning groove 141. The locking blocks 146 are compressed by the inner wall of the positioning groove 141, compressing the spring 144 and causing the locking blocks 146 to retract into the positioning seat 143. When the positioning seat 143 moves to the appropriate position and the locking blocks 146 align with the fixing holes 142, the spring 144 releases its elastic potential energy, pushing the moving block 145 outward. This allows the locking blocks 146 to be inserted into the fixing holes 142 for fixation, facilitating quick and easy replacement of the grinding brush 148 and maintaining a good grinding effect.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
