[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-3 , the utility model provides an embodiment: a composite insulator joint laser marking positioning device, comprising a chassis 1 and a laser marking head body 2, the laser marking head body 2 is located on the top side of the chassis 1, the outer wall of the laser marking head body 2 is fixedly connected to a frame 3, the bottom side of the frame 3 is connected to a switching head 5, the driving end of a motor 4 installed on the top side of the frame 3 is fixedly connected to the top side of the switching head 5, the top of the outer wall of a collecting head 9 fixedly connected to one end of the bottom side of the switching head 5 is fixedly connected to an external joint 10, a plurality of through grooves are provided at the bottom end of the outer wall of the collecting head 9, the input end of the external joint 10 is externally connected to a hose connected to an exhaust gas collection device, the other end of the bottom side of the switching head 5 is fixedly connected to a sleeve 6, a positioning needle 7 is provided on the bottom side of the sleeve 6, the top end of the positioning needle 7 is slidably connected to the inside of the sleeve 6 through a spring 8, one end of the spring 8 is connected to the top side of the inner wall of the sleeve 6, and the other end of the spring 8 is connected to the top side of the positioning needle 7;

[0023] Specifically, the laser marking head body 2 is externally connected to an electric movable frame 3 for free movement to assist the movement, thereby laser marking the insulator joint. The inner wall of the sleeve 6 is a special-shaped groove, and the shape of the top of the positioning pin 7 corresponds to it, so as to prevent the positioning pin 7 whose bottom needle head is consistent with the laser head at the bottom side of the laser marking head body 2 from twisting and deviating, thereby improving the positioning accuracy. The laser marking head body 2 drives the frame body 3 connected thereto and the structure including the positioning pin 7 on the bottom side of the frame body 3 to move for positioning. When the positioning pin 7 abuts against the determined position and completes the positioning, the spring 8 will be compressed for buffering to prevent the needle from excessively contacting the composite insulator to avoid bending of the positioning pin 7, thereby extending the service life and long-term accuracy of the positioning pin 7. By starting the motor 4 to drive the switching head 5 on the bottom side to rotate, the switching head 5 can drive the positioning pin 7 and the collecting head 9 on the bottom side to switch positions. The collecting head 9 comes to a position close to the laser marking head body 2. When laser marking is performed, the harmful gas generated will be collected by the collecting head 9 of the hose connected to the exhaust gas collection device to prevent the harmful gas from damaging the health of employees.

[0024] The left end of the top side of the chassis 1 is fixedly connected with a support frame 11, the right end of the support frame 11 is connected to a limit frame 13 through a motor 2 12, a motor 3 14 is installed on the front side of the limit frame 13, the inner wall of the limit frame 13 is rotatably connected with a bidirectional screw 15, the front end of the bidirectional screw 15 is fixedly connected to the driving end of the motor 3 14, the left end of the curved piece 16 is threadedly connected to the outer wall of the bidirectional screw 15, the right ends of the two curved pieces 16 are fixedly connected with a clamping head 17 on one side thereof, the shape of the clamping head 17 is arc-shaped, and a groove is provided on one side thereof;

[0025] Specifically, the arc-shaped structure of the clamping head 17 cooperates with the groove to clamp the disc-shaped structure of the composite insulator. When the composite insulator is loaded and clamped and positioned, the composite insulator is placed between the two clamping heads 17, and the motor three 14 is started, so that the motor three 14 drives the bidirectional screw 15 to rotate, and drives the two curved pieces 16 connected to the clamping heads 17 to move toward each other. Since the inner wall shape of the limit frame 13 corresponds to the left end shape of the curved piece 16, the curved piece 16 driven by the bidirectional screw 15 can be prevented from rotating, so that it can move normally, thereby clamping and positioning the disc-shaped structure of the composite insulator, and adapting to composite insulators of different specifications, the joint of the composite insulator faces the right end.

[0026] Working principle: Before laser marking the composite insulator joint, the composite insulator needs to be loaded and clamped, that is, the first positioning, by placing the composite insulator between the two clamping heads 17 and starting the motor three 14, so that the motor three 14 drives the bidirectional screw 15 to rotate, and drives the two curved pieces 16 connecting the clamping heads 17 to move toward each other, so that the disc-shaped structure of the composite insulator is clamped and positioned, and the joint of the composite insulator faces the right end. Driven by motor 2 12, the limit frame 13 fixed to the driving end of motor 2 12 rotates together with the structure including the clamping head 17 on the right side of the limit frame 13, thereby rotating the clamped composite insulator, changing its angle, and selecting a suitable position for marking. After determining the approximate position, the laser marking head body 2 drives the frame 3 connected thereto and the structure including the positioning pin 7 on the bottom side of the frame 3 to move. When the positioning pin 7 abuts against the determined position to complete the positioning, start motor 1 4, and motor 1 4 drives the switching head 5 on the bottom side to rotate, so that the switching head 5 drives the positioning pin 7 and the collecting head 9 on the bottom side to switch positions. The collecting head 9 comes to a position close to the laser marking head body 2. When laser marking is performed, the harmful gas generated will be collected by the collecting head 9 of the hose connected to the exhaust gas collection device to prevent the harmful gas from damaging the health of employees.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
