Description

Technical Field

[0001] The utility model relates to bearing production, which belongs to the technical field, and particularly relates to a fixing device for bearing production. Background Art

[0002] Bearings are a key component in mechanical equipment. They are mainly used to support mechanical rotating bodies, reduce friction during movement, and ensure the accuracy and stability of the rotating body's rotation. Bearings are usually composed of inner rings, outer rings, rolling elements (such as balls or rollers) and cages. The load is transmitted and smooth rotation is ensured through the mutual cooperation of the inner and outer rings and the rolling of the rolling elements. The bearing production fixture is a special tool used to accurately and firmly clamp the bearing raw materials (such as steel pipes or steel rings) during the bearing production process. This device ensures that the bearing maintains the correct position during processing, testing or assembly, prevents it from unnecessary movement, and ensures process quality. The existing bearing production fixture fixes the outer arc surface of the bearing raw material, which is inconvenient for personnel to process the outer arc surface of the bearing raw material.

[0003] For example, the utility model with announcement number CN210413993U discloses a fixing device for bearing production. In this patent scheme, the outer arc surface of the raw material of the processed bearing is fixed by a fixing mechanism, and the bearing cannot be fixed internally. Due to the obstruction of the fixing mechanism on the outer arc surface of the raw material of the bearing, it is inconvenient for the processing device to perform cutting and grinding on the outer arc surface of the raw material of the bearing. Utility Model Content

[0004] In view of this, the utility model aims to solve the shortcomings of the prior art and provide a fixing device for bearing production, which can internally support and fix the bearing raw material, ensuring the stable fixation of the bearing raw material while making it more convenient for the processing device to process the outer arc surface of the bearing raw material, thereby greatly improving the production efficiency of the bearing.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a fixing device for bearing production, including a mounting plate, a frame plate is welded and fixed on the upper end of the mounting plate, three inner supporting arc frames distributed at equal angles are slidably arranged inside the frame plate, a driving mechanism for driving the inner supporting arc frames to move is arranged inside the frame plate, a downward pressing fixing mechanism for fixing the upper end of the bearing is arranged on the rear side of the upper end of the mounting plate, the driving mechanism includes a screw rod rotatably arranged inside the frame plate, a rotating frame is threadedly connected to the outer side surface of the screw rod, three connecting frames are rotatably connected to the inside of the rotating frame, a rotating seat is arranged on the inner side surface of the three inner supporting arc frames, and the lower ends of the three connecting frames are connected to the frame plate. The internal rotation connection of the rotating seat is arranged, and the upper end of the mounting plate is provided with an electric drive unit for driving the screw to rotate, and the electric drive unit includes a motor arranged on the upper end of the mounting plate, and the output shaft of the motor is connected to the lower end of the screw through a coupling, and the downward pressing fixing mechanism includes a connecting plate fixed to the rear side of the upper end of the mounting plate by bolts, and the internal sliding connection of the connecting plate is provided with a limiting column, and the lower end of the limiting column is provided with a pressing ring, and the internal threaded hole opened at the upper end of the connecting plate is threadedly connected with a screw, and the lower end of the screw is rotatably connected with the upper end of the pressing ring, and the upper end of the screw is provided with an auxiliary rotating assembly, and the auxiliary rotating assembly includes a handwheel arranged at the upper end of the screw, and a protective cover is wrapped on the outer arc surface of the handwheel.

[0006] As a further improvement of the utility model, mounting holes are provided at the four corners of the mounting plate.

[0007] As a further improvement of the utility model, a control panel is arranged on the upper end of the mounting plate, and the motor is electrically connected to the control panel.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] Firstly, by inserting the bearing material to be processed into the three inner support arc frames, and then controlling the motor to start running, the output shaft rotates to drive the screw to rotate, so that the rotating frame moves downward, and the internal connecting frame rotates and expands toward each other, driving the three inner support arc frames on the rotating seat to move away from each other to achieve the inner support fixation of the bearing material, and then turning off the motor operation, the bearing material can be fixed by the inner support, which ensures the stability of the bearing material while making it easier for the processing device to process the outer arc surface of the bearing material, greatly improving the production efficiency of the bearing.

[0010] Secondly, when it is necessary to fix the upper end of the bearing raw material, the connecting plate is installed to the mounting plate by bolts, and then the hand wheel is rotated so that the pressure ring on the screw is restricted by the limit column and moves downward to cooperate with the frame plate to fix the upper and lower ends of the bearing raw material, making subsequent processing more stable.

[0011] Thirdly, the anti-skid cover on the hand wheel can prevent the personnel from slipping when rotating the hand wheel, making it easier for the personnel to rotate the hand wheel.

[0012] Fourthly, the fixing device can be quickly fixed on the processing device through the mounting hole, which is convenient for personnel to fix the fixing device. BRIEF DESCRIPTION OF THE DRAWINGS
