Description

Technical Field

[0001] This invention relates to the field of bearing machining technology, and in particular to an inner ring turning device for bearing machining that facilitates chip removal. Background Technology

[0002] In the field of mechanical manufacturing, bearings, as the core basic component of the transmission system, directly affect the service performance and service life of the entire machine through their machining accuracy and efficiency. The inner ring of a bearing, as a crucial component, has a decisive impact on the bearing's assembly accuracy and operational reliability due to its machining quality. With the rapid development of high-end equipment manufacturing, more stringent requirements have been placed on the machining accuracy and surface integrity of key parts of the bearing inner ring—such as the inner bore and raceways—making the turning process increasingly important in the process chain. Currently, the turning of bearing inner rings is generally carried out using CNC lathes or dedicated turning production lines. During the machining process, a chuck is typically used to position and clamp the bearing inner ring blank, and then a cutting tool is used to cut and shape its inner circle, flanges, raceways, and oil grooves.

[0003] Chinese patent CN118527682B discloses a roller bearing groove turning device, relating to the field of turning technology. To address damage issues, it specifically includes a base. The top of the base is driven by opposing drive mechanisms to connect two carriages: a first carriage and a second carriage. The top of the first carriage has a clamping mechanism, and the top of the second carriage has a turning mechanism. The clamping mechanism employs a three-jaw chuck structure, with an extended chuck at the inner end of each jaw. This invention, by using an extended chuck, utilizes an abutment rod and clamping arm to simultaneously clamp the outer wall of the outer ring, thereby increasing the contact points, reducing clamping pressure, and preventing outer ring deformation. Furthermore, the linkage between the abutment rod and clamping arm is achieved using a gear and a tooth groove, enabling the clamping of outer rings of different diameters while maintaining rigid clamping stability. However, this device cannot simultaneously collect and separate dust and debris generated during processing, leading to the disorderly diffusion of dust-laden gas within the workshop, thus affecting the operating environment.

[0013] This invention provides a turning device for inner ring machining of bearings that facilitates chip removal. It has the following advantages: 1. This bearing inner ring turning equipment, which facilitates chip removal, uses a dust collection device to draw dust and falling chips generated during machining into a dust collection frame and discharge them into a processing cylinder through a dust outlet pipe. The gas and chips entering the processing cylinder pass through a filter screen, which filters the chips and dust in the gas. The filtered gas is then discharged through a vacuum pump, achieving simultaneous collection and gas-solid separation of machining dust and chips, thus improving the working environment.

[0014] 2. This bearing inner ring turning equipment, which facilitates chip removal, utilizes a scraper and an arc-shaped actuating plate. A second drive motor, via a rotating rod, drives a sealing plug to slide out of the processing cylinder. Simultaneously, the rotating rod moves the arc-shaped actuating plate via a rotating disc. This movement of the arc-shaped actuating plate pushes out the waste chips from the processing cylinder, improving the convenience of material discharge and removing accumulated waste chips. This prevents waste chips from accumulating inside the cylinder or in dead corners, ensuring the cleanliness of the processing cylinder. Furthermore, when the rotating rod drives the scraper close to the filter screen, the second drive motor, activated, rotates the rotating rod, which in turn drives the scraper to clean one side of the filter screen, preventing waste chips from clogging it.

[0015] 3. This bearing inner ring turning equipment, which facilitates chip removal, uses an air jet device to draw external coolant from the inlet pipe into the spiral heat exchange tube via a pump. The coolant in the spiral heat exchange tube exchanges heat with the gas entering the cooling cylinder, cooling the gas. Then, a one-way valve is opened to discharge the cooled gas into the arc-shaped exhaust frame, and finally, the gas is blown towards the clamping assembly through the air jet nozzle, thus cooling the workpiece at the clamping assembly. This achieves directional and efficient air cooling of the turning area.

[0016] 4. This bearing inner ring turning equipment, which facilitates chip removal, uses an arc-shaped exhaust frame and a dust collection frame to ensure that the gas ejected from the exhaust nozzle blows vertically downwards towards the clamping assembly. Meanwhile, the dust collection frame is located directly below the clamping assembly to collect dust. The two form a directional airflow channel of "blowing from above and sucking from below," which avoids the disorderly diffusion of dust-laden airflow in the workshop and achieves synergistic cooling and dust removal functions.

[0019] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] For the first embodiment, please refer to... Figures 1-6 This invention provides a technical solution: In use, the operator places the workpiece to be processed into the clamping assembly 12, which clamps and fixes it. Then, the first electric slide rail 3 is activated, and the electric slider inside the first electric slide rail 3 drives the movable frame 4 to move. The movable frame 4 then drives the turning tool assembly 5 to move to the designated position for turning the workpiece. While the workpiece is being processed, the first drive motor 10 is activated. The output end of the first drive motor 10 drives the clamping assembly 12 to rotate via the belt drive assembly 11. The clamping assembly 12 then... It can drive the workpiece to rotate, and rotate the workpiece to different angles to cooperate with the turning tool assembly 5 for turning. While the workpiece is being processed, the vacuum pump 65 is turned on to suck the dust and falling waste generated during processing into the dust collection frame 61 and discharge it into the processing cylinder 63 through the dust outlet pipe 62. The gas and waste entering the processing cylinder 63 pass through the filter screen 66. The filter screen 66 filters the waste and dust in the gas. The filtered gas is then discharged through the vacuum pump 65, realizing the simultaneous collection and gas-solid separation of processing dust and waste, which improves the working environment.

[0021] When it is necessary to clean the waste inside the processing cylinder 63, the second electric slide rail 613 is activated. The electric slider inside the second electric slide rail 613 drives the limit slider 612 to slide within the limit slide frame 611. The limit slider 612 drives the second drive motor 69 to move via the bracket. The second drive motor 69 drives the sealing plug 67 to slide out of the processing cylinder 63 via the rotating rod 68. At the same time as the rotating rod 68 slides out, it drives the arc-shaped actuating plate 616 to move via the rotating disk 614. The arc-shaped actuating plate 616 moves... During operation, the waste in the processing cylinder 63 can be pushed out, improving the convenience of material discharge and removing accumulated waste in the processing cylinder 63. This avoids the problem of waste residue accumulating in the cylinder or dead corners, ensuring the cleanliness of the processing cylinder. At the same time, when the rotating rod 68 drives the scraper 615 to approach the filter screen 66, the second drive motor 69 is turned on and drives the rotating rod 68 to rotate. The rotating rod 68 can then drive the scraper 615 to clean one side of the filter screen 66, preventing waste from clogging the filter screen 66.

[0022] For the second embodiment, please refer to... Figures 1-8The present invention provides a technical solution: Based on the first embodiment, in use, the air exchange pump 92 is turned on to draw external gas into the cooling cylinder 91, and the liquid pump 99 is turned on to draw external coolant from the liquid inlet pipe 98 into the spiral heat exchange tube 96. The coolant entering the spiral heat exchange tube 96 exchanges heat with the gas entering the cooling cylinder 91 to cool the gas. Then, the one-way valve 93 is turned on to discharge the cooled gas into the arc-shaped exhaust frame 94. Finally, the gas is blown towards the clamping assembly 12 through the jet nozzle 95, which can cool the workpiece at the clamping assembly 12 and achieve directional and efficient air cooling of the turning area.

[0023] The gas ejected from the nozzle 95 blows vertically downwards toward the clamping assembly 12, while the dust collection frame 61 is located directly below the clamping assembly 12 to collect dust. The two form a directional airflow channel of "blowing from above and sucking from below", which avoids the disorderly diffusion of dust-laden airflow in the workshop and achieves the synergistic function of cooling and dust removal.

[0024] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
