[0002] Needle roller bearings are roller bearings with cylindrical rollers, where the rollers are thin and long, and are called needle rollers. This type of bearing is characterized by a compact radial structure and a high load bearing capacity even with a small cross section. The roller diameter is usually no more than 5 mm, and the ratio of length L to diameter D, L / D, is usually greater than or equal to 2.5. When machining needle roller bearings, personnel can choose to use fixtures to assist the needle roller bearings in auxiliary operations.

[0003] In the process of personnel actually using the fixing device, due to the different diameters of the needle roller bearings, the personnel need to adjust the fixing device to adapt to the size of the bearing being processed. However, if the operating steps of the personnel are cumbersome during the adaptation and adjustment process, adding too many steps will reduce the practicality of the fixing device, thereby causing inconvenience to the users. Hereby, a fixing device that can adapt to the processing of needle roller bearings of multiple sizes is proposed. Utility Model Content

The distance between the arc-shaped clamping plates 12 is adjusted to achieve the effect of adapting the diameter of the bearing workpiece. The bidirectional screw 9 is driven by the motor 7 to rotate, and the corresponding two screw sleeves 10 respectively drive the adjacent arc-shaped clamping plates 12 to move, thereby achieving the adjustment of the distance between the two arc-shaped clamping plates 12. Then the personnel controls the cylinder 3 to drive the piston rod 6 to push the fixed plate 4 to move, so that the arc-shaped clamping plate 12 fits the outer ring of the bearing workpiece, thereby achieving the clamping of the diameter of the bearing workpiece. Through the structural design, personnel only need simple adjustment operations to complete the effect of adapting bearing workpieces of different diameters, thereby reducing the difficulty of using the fixing device, bringing great convenience to the actual users, and at the same time, ensuring the quality of stable fixation of the bearing workpiece.

[0025] This program has the following working process:

[0026] When in use, personnel can place the bearing workpiece on the base plate 1, and can adjust the distance between the two corresponding arc-shaped clamping plates 12 according to the diameter of the bearing workpiece that actually needs to be clamped to achieve the effect of adapting the diameter of the bearing workpiece. Driven by the motor 7, the bidirectional screw 9 rotates, and the corresponding two screw sleeves 10 respectively drive the adjacent arc-shaped clamping plates 12 to move, thereby achieving the adjustment of the distance between the two arc-shaped clamping plates 12. Then, personnel control the cylinder 3 to drive the piston rod 6 to push the fixed plate 4 to move, so that the arc-shaped clamping plate 12 fits with the outer ring of the bearing workpiece, thereby achieving the clamping of the diameter of the bearing workpiece.

[0027] According to the above working process, we can know that:

[0028] Through the structural design, personnel only need to make simple adjustments to adapt bearing workpieces of different diameters, thereby reducing the difficulty of using the fixing device, bringing great convenience to actual users, and at the same time ensuring the stable fixation quality of the bearing workpiece.

[0029] Furthermore, one end of the piston rod 6 passes through the adjacent vertical plate 2 through a shaft sleeve and is fixedly connected to one side of the corresponding fixed plate 4. Specifically, through the setting of the piston rod 6 and in cooperation with the cylinder 3, the position of the fixed plate 4 can be changed.

Specifically, the setting of the slider 14 and the slide groove 13 prevents the screw sleeve 10 from rotating along with the bidirectional screw rod 9.

[0033] Furthermore, the two adjacent arc-shaped clamping plates 12 are distributed in a symmetrical state. Specifically, by disposing the arc-shaped clamping plates 12, a better effect of fitting and processing the bearing is achieved.

[0034] To sum up: when personnel use it, they can place the bearing workpiece on the base plate 1, and they can adjust the distance between the two corresponding arc-shaped clamping plates 12 according to the diameter of the bearing workpiece that actually needs to be clamped to achieve the effect of adapting the diameter of the bearing workpiece. Driven by the motor 7, the bidirectional screw rod 9 rotates, and the corresponding two screw sleeves 10 respectively drive the adjacent arc-shaped clamping plates 12 to move, thereby achieving the adjustment of the distance between the two arc-shaped clamping plates 12. Then, personnel control the cylinder 3 to drive the piston rod 6 to push the fixed plate 4 to move, so that the arc-shaped clamping plate 12 fits with the outer ring of the bearing workpiece, thereby achieving the clamping of the diameter of the bearing workpiece. Through the setting of the piston rod 6, in conjunction with the cylinder 3, The position of the fixed plate 4 can be changed. By setting the moving block 15 and cooperating with the displacement groove 5, the fixed plate 4 can maintain stability during the displacement process.
