Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an electrical automation clamping mechanism. Background Art

[0002] The electrical automation clamping mechanism is a commonly used device in electrical engineering. It can clamp the workpiece to facilitate the operator to process the workpiece. Generally speaking, the electrical automation clamping mechanism usually pushes the clamping plate connected to it close to the workpiece from the side of the workpiece through multiple cylinders to achieve clamping of the workpiece. The patent "An Electrical Automation Clamping Mechanism", patent number: CN113910127B, discloses an electrical automation clamping mechanism. The clamping mechanism can effectively distribute the clamping force on the surface of the original through the interaction of multiple clamping blocks and the balance of the clamping force on the original under the action of a single power, preventing the original from being deformed or damaged due to the unbalanced clamping force on the original, reducing the user's cost, improving the user's work efficiency, and improving productivity. The purpose of the electrical automation clamping mechanism to stably clamp the cylindrical original solves the problem of the general electrical automation clamping mechanism holding the cylindrical original unstable. However, the clamping method of the patent can only clamp the tubular workpiece from the outside, which is not suitable for some workpieces that need to be clamped at multiple positions on the outside of the tubular workpiece. In the case of processing, the clamping position needs to be changed many times. At the same time, this clamping mechanism is driven by a motor to move the power shaft left and right. When the power shaft moves to the right, the extension arm pulls the cable, and the cable changes the direction of force through the reversing ring, so that the clamping block moves closer to the center of the clamping shell. When this clamping method is in use, since the cable is a rope that can be bent and straightened, the clamping block can easily block the tubular workpiece under the action of gravity, so that it cannot be moved directly to the position between all the clamping blocks. It is more troublesome to place the tubular workpiece to be clamped on the inside of the clamping mechanism, and the clamping block needs to be manually pushed to move it outward to make room for clamping the tubular workpiece to avoid the clamping block blocking the workpiece. Therefore, it is necessary to further optimize the structure of the electrical automation clamping mechanism to ensure the clamping effect of the electrified tubular workpiece. Utility Model Content

[0025] A first fixed shaft 21 is fixedly provided at the contact position between the first polygonal frame 2 and the rotating rod 5, a through groove 51 which is matched and slidably matched with the first fixed shaft 21 is provided in the middle of the rotating rod 5, a second fixed shaft is fixedly provided at the contact position between the second polygonal frame 4 and the rotating rod 5, and a through hole 52 is also provided at the connection between the rotating rod 5 and the second fixed shaft.

[0026] The driving component 7 includes a bearing 71, a fixing rod 72 and an internal threaded tube 73. The bearing 71 is fixedly arranged at the center position of the electromechanical tube 1 through the fixing rod 72. The internal threaded tube 73 is rotatably arranged inside the bearing 71, and the screw rod 6 passes through the internal threaded tube 73 and is rotatably connected thereto.

[0027] The driving component 7 also includes a motor 74, a driving gear 75 and a driven gear 76. The motor 74 is fixedly arranged on the inner wall of the electromechanical tube 1, the driving gear 75 is fixedly connected to the driving end of the motor 74, and the driven gear 76 is fixedly arranged on the outside of the internal threaded tube 73 and is meshed with the driving gear 75.

[0028] The clamping plate component 8 includes a first connecting shaft 81, a connecting rod 82, a clamping plate 83, a connecting seat 84, a second connecting shaft 85 and a traction spring 86. The first connecting shaft 81 is rotatably set at the end of the rotating rod 5 away from the regular polygon frame 24, the connecting rod 82 is fixedly set at both ends of the first connecting shaft 81, the clamping plates 83 are fixedly set on one side of the connecting rod 82, the connecting seat 84 is fixedly set on the side of the rotating rod 5, the second connecting shaft 85 is fixedly set between the connecting rods 82, and connecting blocks 87 are fixedly set at both ends of the traction spring 86, and the connecting blocks 87 are rotatably connected to the connecting seat 84 and the second connecting shaft 85 respectively, and a rubber pad 88 is also fixedly set on the top of the clamping plate 83.

[0029] A stopper 9 is fixedly provided at one end of the screw rod 6 away from the second polygonal frame 4 , and a mounting plate 10 is also fixedly provided at one side of the electromechanical tube 1 .

[0030] In a specific application of the present invention, since the middle position of the rotating rod 5 is slidably connected to the first polygonal frame 2, and one end of the rotating rod 5 is rotatably connected to the second polygonal frame 4, when the second polygonal frame 4 moves linearly along the axis between the first polygonal frame 2 and the first polygonal frame 2, it can drive the rotating rod 5 rotatably connected thereto to rotate. The number of sides of the first polygonal frame 2 and the second polygonal frame 4 is the same as the number of the clamping plate parts 8. At this time, the spacing between each clamping plate part 8 connected to the other end of the opposite rotating rod 5 changes, so that tubular workpieces with different diameters can be clamped. When the second polygonal frame 4 passes through the first polygonal frame 2, the second polygonal frame 4 can rotate. The clamping plate component 8 moves to the inside of the first polygonal frame 2, and the clamping direction of the clamping plate component 8 is changed from being inclined toward the outside to being inclined toward the inside, and the clamping direction is changed from being inclined toward the outside to being inclined toward the inside. Since the screw rod 6 is driven by the driving component 7 to move linearly along the length direction of the electromechanical tube 1, and the screw rod 6 is fixedly connected to the second polygonal frame 4 through the connecting plate 42, the driving component 7 can control the movement of the second polygonal frame 4, thereby controlling the clamping plate component 8 to clamp, and the internal threaded tube 73 can rotate relative to the bearing 71, and since the screw rod 6 is connected The plate 42 is fixedly connected to the second polygonal frame 4 and cannot rotate, and the internal threaded tube 73 is threadedly connected to the screw rod 6. Therefore, when the internal threaded tube 73 is rotated, the screw rod 6 can move in a straight line. The driven gear 76 fixed to the outside of the internal threaded tube 73 is meshed and connected with the driving gear 75 fixed to the driving end of the motor 74. When the motor 74 is working, it can control the rotation of the internal threaded tube 73. The installation of the stopper 9 can prevent the screw rod 6 from escaping from the internal threaded tube 73. The connecting rod 82 is rotatably connected to the rotating rod 5 through the first connecting shaft 81, so that the clamping plate 83 can rotate. When the inclination angle of the rotating rod 5 is not At the same time, they can all be rotated to a direction perpendicular to the length of the tubular workpiece to ensure the clamping effect, and due to the installation of the traction spring 86, the connecting rod 82 and the rotating rod 5 remain vertical when not subject to external force, and the clamping plates 83 are not affected by gravity and are all facing the ground. There is no need to manually adjust the direction of each clamping plate 83 to clamp the workpiece. At the same time, the installation of the rubber pad 88 can increase the friction between the clamping mechanism and the workpiece to prevent the workpiece from slipping, and the deformation of the rubber pad 88 when squeezing the workpiece can effectively avoid damage to the surface of the workpiece. Therefore, the clamping mechanism has good practicality.
