The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0014] like Figure 1-2The annular forging positioning device for bearing installation shown in the figure comprises a base 1 and a positioning assembly mounted on the base 1, wherein the positioning assembly comprises a fixing plate 1 2 and a fixing plate 2 6, both of which are right-angle bent plates. The fixing plate 1 2 and the fixing plate 2 6 are assembled and mounted above the base 1, and the area between the fixing plate 1 2 and the fixing plate 2 6 is square in shape, the fixing plate 1 2 is fixedly mounted above the base 1, and the fixing plate 2 6 is movably mounted above the base 1. The outer walls of both sides of the fixing plate 1 2 are provided with a notch 1 3, and the end of the fixing plate 2 6 is embedded in the notch 1 3. A slide groove 5 is provided on the table surface of the base 1, and a lead screw 11 is installed on the bottom of the base 1. The fixing plate 2 6 is adapted to be connected with the lead screw 11, and the fixing plate 2 6 is driven by the lead screw 11. A motor 10 is fixedly mounted on the bottom surface of the base 1, and the output end of the motor 10 is fixedly connected with the end of the lead screw 11, and both ends of the lead screw 11 are connected to the bottom surface of the base 1 through bearings.

[0015] The opening position of the slide slot 5 corresponds to the diagonal of the square area formed by the fixed plate 1 2 and the fixed plate 2 6. The bottom surface of the tip of the fixed plate 2 6 is fixedly installed with a movable block 12, and the movable block 12 is threadedly connected with the lead screw 11. A fixed rod 7 is fixedly installed on the upper side of the fixed plate 2 6. A notch 2 4 is opened on the upper outer wall of the fixed plate 1 2, and one end of the fixed rod 7 passes through the notch 2 4. A photoreceptor 9 is fixedly installed on the top surface of the tip of the fixed plate 1 2, and a spotlight 8 is fixedly installed on the top surface of the tip of the fixed plate 2 6. The light source end of the spotlight 8 is installed toward the photoreceptor 9. The spotlight 8 and the photoreceptor 9 are respectively installed at the two ends of the diagonal of the square area formed by the fixed plate 1 2 and the fixed plate 2 6.

[0016] Embodiment: Place the annular forging on the base 1, start the motor 10, drive the lead screw 11 to rotate, the lead screw 11 drives the movable block 12 to start sliding horizontally, the movable block 12 drives the fixed plate 2 6 to slide, the fixed plate 2 6 slides according to the opening direction of the slide groove 5, because the annular forging is a regular circular ring, the fixed plate 2 6 will shrink the square area between the fixed plate 1 2 and the fixed plate 2 6 when moving, and as the fixed plate 2 6 moves, the area between the fixed plate 1 2 and the fixed plate 2 6 will adapt to the size of the circular ring, and the inner walls of the fixed plate 1 2 and the fixed plate 2 6 will fix the annular forging in the shrunk area, fixing the annular forging. In the initial state, the area of ​​the square area is large, and annular forgings of various sizes can be placed, so the positioning assembly can clamp and position annular forgings of different sizes. When installing bearings of different sizes, there is no need to replace equipment, which can improve work efficiency.

[0017] During the movement of the fixed plate 26, the fixed rod 7 slides inside the slot 24, the outer wall of the fixed plate 26 slides inside the slot 13, the rays of the spotlight 8 are aimed at the photoreceptor 9, and the rays of the spotlight 8 are consistent with the diagonal of the square area. When the motor 10 stops running and the fixed plate 26 and the fixed plate 12 clamp the annular forging, the fixed rod 7 reinforces the outer wall of the fixed plate 26 and limits the moving direction of the fixed plate 26 to prevent deformation when the fixed plate 26 clamps the annular forging. The photoreceptor 9 will receive the rays of the spotlight 8. When the motor 10 is running, the photoreceptor 9 always receives the rays of the spotlight 8, which means that the positioning component is operating normally. If the rays of the spotlight 8 are not received for a long time, it means that the fixed plate 26 is offset during operation and cannot accurately position the annular forging. At this time, the photoreceptor 9 sends an electrical signal to stop the motor 10. An operator will check.

[0018] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.

[0019] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
