Description

Technical Field

[0001] This utility model relates to the technical field of cutting devices for machining, specifically a cutting device for precision machining of self-lubricating bearings. Background Technology

[0002] Bearing machining cutting devices are mechanical equipment specifically designed for manufacturing and processing various types of bearings. Bearings are key components used to reduce friction between moving parts, and their precision, surface quality, and dimensional accuracy are crucial to their performance. Therefore, bearing machining requires high-precision cutting techniques and equipment. CNC lathes are widely used in bearing machining, especially in the machining of outer diameters and inner holes. The cutting tools of lathes can perform cutting under high-precision control, mainly for machining the outer diameter, inner hole, and end face of bearings.

[0003] However, during use, the cutting device generates cutting force on the workpiece surface through the contact between the rotating tool and the workpiece, causing the material to be removed layer by layer. The tool in the cutting device cuts according to the movement of the workpiece. The movement of the tool may be rotation, feed, or a combination of both. Different tools and movement modes can complete different processing tasks, such as internal and external cylindrical grinding, end face cutting, etc. When it is necessary to clamp the bearing, the clamping blocks may not be evenly distributed on the bearing surface, resulting in inconsistent clamping force at each contact point. Uneven clamping force leads to local over-clamping or insufficient clamping, and the bearing may loosen during the processing. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1-2 , Figure 4-5As shown in this embodiment, a cutting device for precision machining of self-lubricating bearings includes a cutting table 100 and a clamping assembly 200. The clamping assembly 200 includes a first clamping plate 205 and a second clamping plate 206. A fixed cylinder 214 is installed inside the first clamping plate 205 and the second clamping plate 206. A telescopic spring 223 is provided inside the fixed cylinder 214. A moving block 221 is installed at one end of the telescopic spring 223 and moves inside the fixed cylinder 214. A limit rod 222 is installed at one end of the moving block 221 and a telescopic rod 220 is fixedly installed at one end of the moving block 221. A clamping block 224 is installed at one end of the telescopic rod 220. In actual use, the self-lubricating bearing 216 to be machined is placed in the clamping area of ​​the clamping assembly 200, and the clamping gap between the first clamping plate 205 and the second clamping plate 206 is adjusted within the fixed cylinder 214. One end of the telescopic spring 223 is connected to the movable block 221, and the other end is connected to the inner wall of the fixed cylinder 214. The movable block 221 can move back and forth within the fixed cylinder 214. One end of the movable block 221 is equipped with a limit rod 222 to control the range of movement of the movable block 221. When the device starts working, the telescopic spring 223 provides elastic force, allowing the movable block 221 to move freely within the fixed cylinder 214. By adjusting the position of the movable block 221, the telescopic rod 220 and the clamping block 224 contact the surface of the bearing 216. The clamping blocks 224 are evenly distributed on the surface of the bearing 216 to ensure that each contact point can be evenly clamped, avoiding damage to the bearing 216 or inaccurate processing due to local over-clamping or insufficient clamping. The clamping blocks 224 are firmly in contact with the surface of the bearing 216, allowing for precision cutting or processing, ensuring that the bearing 216 will not loosen during processing.

[0023] The clamping block 224, along with components such as the moving block 221, telescopic spring 223, and limiting rod 222, can clamp bearings 216 of different sizes and shapes, offering strong adaptability and meeting various precision machining requirements. Through the telescopic spring 223 and adjustable clamping gap, the clamping block 224 can be evenly distributed on the surface of the bearing 216, ensuring that each contact point receives a consistent clamping force. This uniform clamping force effectively prevents local over-clamping or insufficient clamping, avoiding damage to the bearing 216 or inaccurate machining. The firm contact between the clamping block 224 and the surface of the bearing 216 prevents the bearing 216 from loosening during machining.

[0024] like Figure 2-4As shown, the lower ends of the first clamping plate 205 and the second clamping plate 206 are bolted to the upper end of the connecting plate 211. One end of the connecting plate 211 is bolted to one end of the first sliding block 203 and the second sliding block 207. The first sliding block 203 and the second sliding block 207 have sliding grooves 215 inside. The inside of the sliding grooves 215 is slidably connected to the sliding guide plate 202. The lower end of the sliding guide plate 202 is bolted to the upper end of the clamping worktable 201. The upper end of the connecting plate 211 is fixedly connected to the connecting rod 212 by the fixing bolt 213. One end of the connecting rod 212 is connected to the upper end of the rotating rod 218 by the movable bolt 219.

[0025] Furthermore, a rotating shaft 217 is fixedly installed at the lower end of the rotating rod 218. The rotating shaft 217 is rotatably connected to the inside of the bearing 216, which is installed inside the clamping worktable 201.

[0026] Furthermore, a fixing block 204 is fixedly installed at one end of the second sliding block 207, a telescopic guide post 210 is installed at one end of the fixing block 204, a telescopic hydraulic cylinder 208 is installed at one end of the telescopic guide post 210, one end of the telescopic hydraulic cylinder 208 is connected to one end of the fixing plate 209 by bolts, and one end of the fixing plate 209 is installed at one end of the clamping worktable 201.

[0027] In actual use, when it is necessary to clamp the workpiece, the telescopic hydraulic cylinder 208 is activated, pushing the telescopic guide column 210 to extend outward. Since one end of the second sliding block 207 is fixed with the fixing block 204, the movement of the telescopic guide column 210 will drive the second sliding block 207 to move along the sliding guide plate 202 towards the first sliding block 203. As the second sliding block 207 moves, the connecting plate 211 will also move accordingly. Since the first clamping plate 205 and the second clamping plate 206 are fixed to the connecting plate 211 by bolts, the movement of the connecting plate 211 is transmitted to the rotating rod 218 through the connecting rod 212, causing the rotating rod 218 to rotate around the rotating shaft 217, thereby driving the first clamping plate 205 and the second clamping plate 206 to close inward, thus achieving the clamping of the workpiece.

[0028] like Figure 1-2 As shown, a sliding rod 104 is installed at the lower end of the clamping worktable 201. The sliding rod 104 is slidably connected to the inside of the cutting worktable 100. A movable slide rail groove 102 is opened inside the cutting worktable 100. A slot 101 is opened inside the cutting worktable 100. The lower end of the slot 101 corresponds to the upper end of the collection box 103. In actual use, the cutting equipment is started to process the bearing 216. The chips or waste generated during the processing fall into the collection box 103 through the slot 101. The slot 101 ensures that the waste can be smoothly discharged from the cutting area and collected in the collection box 103.

[0029] The use of collection box 103 can effectively collect waste generated during processing, reduce pollution in the work area, and improve the cleanliness of the work environment. The slot 101 ensures that the waste can be smoothly discharged from the cutting area.

[0030] This utility model provides a cutting device for precision machining of self-lubricating bearings. The specific working principle is as follows: The self-lubricating bearing 216 to be machined is placed in the clamping area of ​​the clamping assembly 200. The clamping gap between the first clamping plate 205 and the second clamping plate 206 is adjusted. Inside the fixed cylinder 214, one end of the telescopic spring 223 is connected to the moving block 221, and the other end is connected to the inner wall of the fixed cylinder 214. The moving block 221 can move back and forth within the fixed cylinder 214. A limit rod 222 is installed at one end of the moving block 221 to control its movement. The movement range of the movable block 221 is such that when the device starts working, the telescopic spring 223 provides elastic force, allowing the movable block 221 to move freely within the fixed cylinder 214. By adjusting the position of the movable block 221, the telescopic rod 220 and the clamping block 224 contact the surface of the bearing 216. The clamping blocks 224 are evenly distributed on the surface of the bearing 216, ensuring that each contact point can be evenly clamped, avoiding damage to the bearing 216 or inaccurate machining due to local over-clamping or insufficient clamping. The clamping blocks 224 are firmly attached to the surface of the bearing 216. The contact allows for precision cutting or machining, ensuring that the bearing 216 does not loosen during processing. The telescopic hydraulic cylinder 208 is activated, pushing the telescopic guide post 210 outwards. Since one end of the second sliding block 207 is fixed to a fixing block 204, the movement of the telescopic guide post 210 causes the second sliding block 207 to move along the sliding guide plate 202 towards the first sliding block 203. As the second sliding block 207 moves, the connecting plate 211 also moves accordingly. This is because the first clamping plate 205 and the second clamping plate 206 are connected by screws... The bolt is fixed to the connecting plate 211. The movement of the connecting plate 211 is transmitted to the rotating rod 218 through the connecting rod 212, causing the rotating rod 218 to rotate around the rotating shaft 217. This causes the first clamping plate 205 and the second clamping plate 206 to close inward, thereby clamping the workpiece. The cutting equipment is started to process the bearing 216. The chips or waste generated during the processing fall into the collection box 103 through the slot 101. The slot 101 ensures that the waste can be smoothly discharged from the cutting area and collected in the collection box 103.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
