[0002] When the linear bearing seat is processing the positioning hole, in order to ensure the processing accuracy of the linear bearing seat, a positioning mechanism is used to limit and fix the linear bearing seat. For example, the authorization publication number CN218836921U is a linear bearing seat processing positioning structure, which uses a clamping plate to abut against the surface of the bearing seat to achieve the positioning and clamping of the bearing seat.

[0003] Since there are many types of linear bearing seats, each type of linear bearing seat is of different sizes. In the process of clamping the linear bearing seat with a clamping plate, the size of the clamping plate is not easy to adjust. If the clamping plate is too large, it will cause inconvenience to the removal and placement of the smaller linear bearing seat. If the clamping plate is too small, the area of ​​the pressure point is limited when clamping the large linear bearing seat, thereby affecting the clamping effect.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0031] See also Figure 2 The positioning platform 101 shown in the figure is provided with a guide assembly for guiding the movement of the two positioning plates 203, and the guide assembly includes a connecting plate 501 fixedly connected to the positioning platform 101, and a guide groove 502 is provided on the connecting plate 501, and a T-shaped plate 503 is slidably connected to the guide groove 502, and one end of the T-shaped plate 503 is connected to the positioning plate 203;

[0033] Working principle: When the linear bearing seat is processed and positioned, the linear bearing seat is first placed on the positioning platform 101 and located between the two clamping plates 102. Then, the pressure point area of ​​the two clamping plates 102 is adjusted according to the size of the linear bearing seat. During the adjustment process, the first bevel gear 403 at one end of the rotating rod 402 is driven to rotate by rotating the rotating disk 405. Under the mutual meshing transmission action of the first bevel gear 403 and the second bevel gear 404, the driving rod 302 is driven to rotate;

[0034] Since two thread strips 303 with opposite thread rotation directions are provided on the side wall of the driving rod 302, during the rotation of the driving rod 302, the positioning plates 203 at one end of the two sliding plates 202 will be driven to move closer to or away from each other through the threaded engagement transmission action of the thread strips 303 and the guiding action of the guide assembly. When the moving distance of the two positioning plates 203 adapts to the size of the linear bearing seat, the rotation of the rotating disk 405 can be stopped. Finally, through the pushing action of the push rod motor 6, the clamping plate 102 and the positioning plate 203 are abutted against the side wall of the linear bearing seat, thereby completing the processing and positioning of the linear bearing seat. By adjusting the spacing between the two positioning plates 203, while ensuring the convenience of taking and placing a smaller-sized linear bearing seat, the distribution of the area of ​​the pressure point when clamping a larger-sized linear bearing seat is improved, thereby ensuring the clamping effect of the linear bearing seat, and further improving the flexibility of the use of the linear bearing seat processing and positioning device.
