[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a feeding structure for laser marking of precision bearings for machine tool spindles, including a machine body 1, an operating table on the right side of the machine body 1, and a laser head on the left side of the machine body 1. Fixing frames 2 are respectively provided on both sides of the laser head on the machine body 1, and a servo motor 3 is provided inside the fixing frame 2. One end of the output shaft of the servo motor 3 is connected to the driving wheel through a coupling, and a driven wheel is correspondingly provided on one side of the driving wheel between the fixing frames 2. The driving wheel and the driven wheel are provided with a conveyor belt 4 on the outer wall, and multiple sets of precision bearings 12 are placed on the conveyor belt 4.

[0019] Furthermore, under the action of the servo motor 3, the conveyor belt 4 forms a conveying structure through the driving wheel, the driven wheel and the fixed frame 2, so that the servo motor 3 can drive the conveyor belt 4 to automatically feed multiple sets of precision bearings.

[0020] Multiple sets of engaging grooves 7 are evenly opened on both sides of the upper end face of the conveyor belt 4, and L-shaped limiting rods 6 are inserted into the engaging grooves 7 respectively. The L-shaped limiting rods 6 are respectively set on the motor box 5, and the motor box 5 is provided with sliding rods 8 on both outer walls. Sliding grooves are opened on the upper and lower sides of the conveyor belt 4 on the opposite side of the fixed frame 2, and the other end of the sliding rod 8 is inserted into the sliding groove.

[0021] Furthermore, the motor box 5 is inserted into the engagement groove 7 by an L-shaped limiting rod 6 to form an engagement and limiting structure with the conveyor belt 4, and the motor box 5 is inserted into the sliding groove by a sliding rod 8 to form a sliding structure with the fixed frame 2. Thus, the L-shaped limiting rod 6 and the sliding rod 8 ensure that the conveyor belt 4 can drive the motor box 5 to move back and forth.

[0022] The motor box 5 houses a motor 9, which has an output shaft. The output shaft has a spiral groove, and a spiral block 10 is spiraled inside the spiral groove. A rotating rod 11 is mounted on the spiral block 10, and threads are provided on the outer walls of both ends of the rotating rod 11. Multiple sets of precision bearings 12 are inserted through the rotating rod 11, and nuts 13 are spiraled on both ends of the rotating rod 11. It should be noted that the rotating rod 11 is made of rubber to ensure the friction between the rotating rod 11 and the precision bearings 12. During placement, the appropriate number of precision bearings 12 should be placed according to the length of the rotating rod 11 to ensure that the rotating rod 11 can drive the multiple sets of precision bearings 12 to rotate.

[0023] Furthermore, the nut 13 and the rotating rod 11 form a spiral locking structure, and the nut 13 and the precision bearing 12 form a compression limiting structure, thereby compressing and limiting multiple sets of precision bearings 12 through the nut 13, so that the rotating rod 11 can drive multiple sets of precision bearings 12 to rotate.

[0024] Working principle: Using the laser marking feeding structure for precision bearings on machine tool spindles, if laser marking is required on the top and bottom of the precision bearings 12, they can be placed directly on the conveyor belt 4. Then, the servo motor 3 can be started. The output shaft of the servo motor 3 drives the drive wheel to rotate via a coupling, which in turn drives the conveyor belt 4 via the driven wheel, thus automatically feeding multiple sets of precision bearings 12. If laser marking is required on the side of the precision bearings 12, first, select a rotating rod 11 of appropriate diameter according to the size of the precision bearing 12, and screw the nut 13 onto the lower end of the rotating rod 11. Then, place multiple sets of precision bearings 12 interlaced on the rotating rod 11, and finally screw another set of nuts 13 onto the rotating rod 11. The upper end is used to squeeze and limit the two ends of the precision bearing 12 through two sets of nuts 13, so as to ensure that the subsequent rotating rod 11 can drive multiple sets of precision bearings 12 to rotate, so as to laser mark the side of the precision bearing 12. After the precision bearing 12 is placed, the rotating rod 11 can be installed on the output shaft of the motor 9 through the spiral block 10. Then, the motor box 5 is placed on the conveyor belt 4 and locked and limited by the L-shaped limiting rod 6. At the same time, the slide rod 8 is inserted into the slide groove on the fixed frame 2, so as to ensure that the motor box 5 can move synchronously with the conveyor belt 4, thereby ensuring that multiple sets of precision bearings 12 that need to be marked on the side can be automatically fed. This is the usage process of the feeding structure for laser marking of precision bearings on the machine tool spindle.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
