Description

Technical Field

[0001] This utility model relates to the field of insulator processing technology, specifically to a positioning mechanism for cutting off the flash of an insulator. Background Technology

[0002] Composite insulators are a common type of insulator used in power construction. They have silicone rubber skirts on the outside. During the molding of silicone rubber skirts, there are often flashes. Therefore, laser equipment is needed to remove these flashes during the processing of the skirts so that the skirts meet the production requirements.

[0003] When cutting off the burrs on insulator skirts, they need to be positioned using clamps. However, because the silicone rubber material of the skirts is relatively soft, the clamps are not secure enough when tightened, causing the skirts to easily detach from the clamps during burr cutting. Therefore, there is an urgent need to design a positioning mechanism for cutting burrs on insulators to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a positioning mechanism for cutting off the flash of an insulator, so as to solve the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A positioning mechanism for cutting off flash from insulators includes a mounting plate. A cylinder is connected to the bottom of the mounting plate by a bearing. A rotating disk is fixed to the top of the cylinder, which extends to the top of the mounting plate. The top of the rotating disk is provided with centrally symmetrically distributed claws. A connecting sleeve is provided inside each claw. A spring is provided inside the connecting sleeve. An iron ring is provided on the top of the spring. Evenly distributed balls are provided on the top of the iron ring. An insulator skirt is sleeved on the outside of the claws. A baffle is provided on the top of the insulator skirt. A plug is fixed at the bottom center of the baffle. The plug is inserted into the connecting sleeve. The outer wall of the plug has an annular groove adapted to the balls. The inner wall of the connecting sleeve has a conical surface.

[0007] Furthermore, the bottom of the claw is slidably connected to the rotating disk, the bottom of the mounting plate is fixed with an electric telescopic rod, the output end of the electric telescopic rod extends to the bottom of the connecting sleeve, the output end of the electric telescopic rod is connected to a conical body with a bearing, and the outer wall of the claw near the conical body is provided with an inclined surface.

[0008] Furthermore, a rotary drive mechanism is provided on one side of the cylinder, and the bottom of the connecting sleeve is fixed to the conical body.

[0009] Furthermore, a feeding clamp is provided at the top of the insulator skirt, and a loading and unloading mechanism is provided inside the feeding clamp.

[0010] Furthermore, the outer wall of the claw is provided with a groove, and an annular spring is provided inside the groove.

[0011] Furthermore, the loading and unloading mechanism is located at the top of the baffle, and an electromagnet is provided inside the cone-shaped body and fixed to the output end of the electric telescopic rod, with a gap between the electromagnet cone-shaped bodies.

[0012] In the above technical solution, the positioning mechanism for cutting off the flash of an insulator provided by this utility model has the following advantages: the ball engages with the annular groove of the plug pin through the elastic force of the spring, and the conical surface guides the ball, preventing the plug pin from being pulled out from the inside of the connecting sleeve in its natural state. This allows the baffle to block the insulator skirt and prevent the insulator skirt from disengaging from the claw during positioning. The electric telescopic rod drives the conical body to move downward, allowing the conical body to squeeze the inclined surface of the claw, thereby enabling multiple claws to move synchronously and providing a better centering effect when fixing the insulator skirt. The electromagnet attracts the iron ring, causing the ball to disengage from the annular groove due to the lack of pressure from the iron ring, making it easy to pull the plug pin out from the outside of the claw.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown in the figure, the positioning mechanism for cutting off the flash of an insulator provided in this embodiment of the utility model includes a mounting plate 1. A cylinder 2 is connected to the bottom bearing of the mounting plate 1. A rotating disk 3 is fixed to the top of the cylinder 2 extending to the top of the mounting plate 1. A centrally symmetrically distributed claw 4 is provided on the top of the rotating disk 3. A connecting sleeve 21 is provided inside the claw 4. A spring 11 is provided inside the connecting sleeve 21. An iron ring 10 is provided on the top of the spring 11. Evenly distributed balls 9 are provided on the top of the iron ring 10. An insulator skirt 5 is sleeved on the outside of the claw 4. A baffle 6 is provided on the top of the insulator skirt 5. A plug pin 7 is fixed at the bottom center of the baffle 6. The plug pin 7 is inserted into the connecting sleeve 21. An annular groove 8 adapted to the balls 9 is provided on the outer wall of the plug pin 7. A conical surface 13 is provided on the inner wall of the connecting sleeve 21.

[0022] Specifically, in this embodiment, a mounting plate 1 is included. A cylinder 2 is connected to the bottom bearing of the mounting plate 1. The cylinder 2 is hollow inside. A rotating disk 3 is fixed to the top of the cylinder 2, which extends to the top of the mounting plate 1. The center of the rotating disk 3 has a through hole with the same inner diameter as the cylinder 2. The top of the rotating disk 3 is provided with centrally symmetrically distributed claws 4. Preferably, there are four claws 4. A connecting sleeve 21 is provided inside the claws 4. The connecting sleeve 21 is located at the center of the four claws 4. A spring 11 is provided inside the connecting sleeve 21. An iron ring 10 is provided on the top of the spring 11. The top of the iron ring 10 is provided with... There are evenly distributed balls 9, preferably three balls 9. An insulator skirt 5 is sleeved on the outside of the claw 4. The insulator skirt 5 is a skirt with cut-off burrs. A baffle 6 is provided on the top of the insulator skirt 5. A plug pin 7 is fixed at the bottom center of the baffle 6. The plug pin 7 is inserted into the inside of the connecting sleeve 21. The outer wall of the plug pin 7 is provided with an annular groove 8 that matches the balls 9. The inner wall of the connecting sleeve 21 is provided with a conical surface 13. The spring 11 applies elastic force to the iron ring 10, so that the iron ring 10 compresses the balls 9, thereby making the balls 9 tend to come together in their natural state.

[0023] The present invention provides a positioning mechanism for cutting off the flash of an insulator. The ball 9 cooperates with the annular groove 8 of the plug pin 7 through the elastic force of the spring 11, and the tapered surface 13 guides the ball 9 so that the plug pin 7 cannot be pulled out from the inside of the connecting sleeve 21 in its natural state. This allows the baffle 6 to block the insulator skirt 5 and prevent the insulator skirt 5 from disengaging from the claw 4 during positioning.

[0024] In another embodiment of this utility model, the bottom of the claw 4 is slidably connected to the rotating disk 3, and an electric telescopic rod 15 is fixed to the bottom of the mounting plate 1. The output end of the electric telescopic rod 15 extends to the bottom of the connecting sleeve 21, and a cone 17 is connected to the output end of the electric telescopic rod 15 by a bearing. An inclined surface 22 is provided on the outer wall of the claw 4 near the cone 17. The electric telescopic rod 15 drives the cone 17 to move downward, so that the cone 17 can squeeze the inclined surface 22 of the claw 4, thereby causing the multiple claws 4 to move away from each other, thus achieving the function of pressing the insulator skirt. 5. The internal tensioning and fixing effect is achieved by driving the cone 17 downward through the electric telescopic rod 15. The multiple claws 4 can move synchronously during the movement, so that the rotation center of the insulator skirt 5 corresponds to the rotation center of the cylinder 2, thereby giving the insulator skirt 5 a better centering effect when fixed. The outer wall of the claw 4 is provided with a groove 18, and the inside of the groove 18 is provided with a ring spring 19. The ring spring 19 makes the multiple claws 4 keep the tendency to close together in the natural state, so that when the cone 17 does not squeeze the claws 4, the claws 4 can return to their original position and close together.

[0025] In another embodiment of this utility model, a rotary drive mechanism 16 is provided on one side of the cylinder 2, and the bottom of the connecting sleeve 21 is fixed to the cone 17. The rotary drive mechanism 16 is used to drive the cylinder 2 to rotate, so that the insulator skirt 5 can rotate after being fixed. At this time, the laser cutting component of the laser equipment is moved to the edge of the insulator skirt 5, so that the burrs on the edge of the insulator skirt 5 can be cut off.

[0026] In another embodiment of this utility model, a feeding clamp 14 is provided on the top of the insulator skirt 5. The feeding clamp 14 is installed with a feeding robot arm. The feeding clamp 14 adsorbs the insulator skirt 5 through a suction cup. The feeding clamp 14 is provided with a loading and unloading mechanism 20. The loading and unloading mechanism 20 is composed of a servo cylinder and a negative pressure adsorption component. The negative pressure adsorption can adsorb and fix the baffle 6. The servo cylinder can insert or pull out the plug pin 7 into the connecting sleeve 21. The loading and unloading mechanism 20 is located on the top of the baffle 6. An electromagnet 12 fixed to the output end of the electric telescopic rod 15 is provided inside the cone 17. There is a gap between the electromagnet 12 and the cone 17. When in use, the power supply of the electromagnet 12 is turned on. The electromagnet 12 can adsorb the iron ring 10 downward, so that the iron ring 10 compresses the spring 11. At this time, the ball 9 is not squeezed by the iron ring 10 and is separated from the annular groove 8. Therefore, the plug pin 7 can be pulled out through the loading and unloading mechanism 20.

[0027] Working principle: During use, the feeding clamp 14 adsorbs and fixes the insulator skirt 5. Then, the robotic arm fits the insulator skirt 5 onto the outside of the claw 4. The electric telescopic rod 15 drives the conical body 17 to move downward, causing the conical body 17 to press against the inclined surface 22 of the claw 4, causing the multiple claws 4 to move away from each other. This fixes the insulator skirt 5 from the inside through the claws 4. At the same time, the loading and unloading mechanism 20 inserts the plug 7 at the bottom of the baffle 6 into the inside of the connecting sleeve 21. Due to the elastic force of the spring 11, the iron ring 10 presses against the ball 9, allowing the ball 9 to maintain a fit with the annular groove 8 of the plug 7 through the action of the conical surface 13. Furthermore, due to the action of the conical surface 13, when the plug 7 is pulled outward, the ball 9 engages with the plug 7. The increased pressure prevents the plug pin 7 from disengaging from the connecting sleeve 21, thus achieving the blocking effect of the baffle 6 on the insulator skirt 5. This effectively prevents the insulator skirt 5 from disengaging from the claw 4. Then, the feeding clamp 14 is disengaged from the insulator skirt 5, and the loading and unloading mechanism 20 is disengaged from the baffle 6. The cylinder 2 is rotated by the rotary drive mechanism 16, which allows the insulator skirt 5 to rotate. When it is necessary to remove the plug pin 7, the power supply of the electromagnet 12 is turned on, so that the electromagnet 12 can attract the iron ring 10 downward, causing the iron ring 10 to compress the spring 11. This causes the ball 9 to disengage from the annular groove 8 without being squeezed by the iron ring 10. At this time, the plug pin 7 can be pulled out by the loading and unloading mechanism 20.

[0028] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
