Description

Technical Field

[0001] The invention relates to an integrated clamping device for processing post insulators. Background Art

[0002] During the machining of post insulators, operations such as repairing shrouds, assembling flanges, or repairing seals often require clamping and securing the insulators. Traditional clamping devices present several challenges: Most require the operator to remove the insulator from the fixture, manually adjust its position, and then re-clamp it to achieve machining at different angles. This repeated disassembly and assembly not only consumes time and reduces production efficiency, but also can affect machining accuracy due to inconsistent clamping.

[0003] Furthermore, some rotatable clamping devices lack stability, potentially causing them to wobble or loosen during post insulator rotation, affecting machining accuracy and potentially posing safety hazards to equipment and operators. Furthermore, these devices are often complex to operate, requiring manual intervention and adjustments, making them difficult to implement in automated machining. Summary of the Invention

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 3 As shown, the integrated clamping device for processing post insulators of the present invention includes a clamping arm 1, a clamping arm cylinder 2, a gear 3, a roller assembly 4, a roller cylinder 5 and a mounting seat 6.

[0021] The two clamping arms 1 are symmetrically arranged and rotatably connected to a mounting base 6. Each clamping arm 1 is fitted with a gear 3, which meshes with each other. The base of the clamping arm cylinder 2 is hingedly connected to one clamping arm 1, while the cylinder shaft of the clamping arm cylinder 2 is hingedly connected to the other clamping arm 1. A roller assembly 4 is slidably connected to the clamping surface of each clamping arm 1. Each roller assembly 4 is driven by a roller cylinder 5, and both roller cylinders simultaneously drive the roller assemblies 4 toward or away from each other.

[0022] The clamping arm 1 is provided with an arcuate clamping surface, on which two locking blocks 11 are symmetrically positioned. The roller assembly 4 is positioned between the two locking blocks 11, and the roller cylinder 5 drives the roller assembly 4 in the radial direction of the arcuate clamping surface. A mounting block 12 is hingedly connected to the clamping arm 1, and the arcuate locking block 11 is fixed to the mounting block 12. The clamping surface of the locking block 11 is provided with a plurality of anti-slip teeth.

[0023] The roller assembly 4 includes a roller 41 and a slide 42 . The slide 42 is slidably connected to the clamping arm 1 . The two rollers 41 are arranged up and down and rotatably connected to the slide 42 . The roller cylinder 5 is fixedly connected to the slide 42 .

[0024] The mounting base 6 is provided with a slide groove 61 for sliding connection to the frame to adjust the distance between the two clamping devices to accommodate post insulators of different lengths.

[0025] When machining post insulators, two clamping devices are first installed on the machine frame. The distance between the two clamping devices is adjusted according to the length of the post insulator using the slide slot 61. The design of the slide slot 61 makes it very convenient to adjust the position of the clamping devices on the machine frame, eliminating the need for complex disassembly and reassembly. This greatly improves the flexibility and applicability of the equipment, allowing it to quickly adapt to the machining needs of post insulators of different specifications.

[0026] The two ends of the post insulator are extended into the arc clamping groove between the two clamping arms 1. The arc clamping surface on the clamping arm 1 matches the shape of the post insulator, which can ensure a larger contact area between the clamping arm 1 and the post insulator, thereby providing more stable support and more uniform force distribution during the clamping process, effectively preventing the post insulator from sliding or shaking during processing, and improving processing accuracy and safety.

[0027] In the initial state, the arc surface of roller 41 in roller assembly 4 lies inward of the clamping surface of locking block 11, preventing the arc surface of roller 41 from interfering with the clamping of the post insulator. This ensures that clamping arm 1 is not affected by roller assembly 4 during the initial clamping phase, allowing it to directly and effectively clamp the post insulator, improving clamping efficiency.

[0028] When the post insulator needs to be fixed, the clamping arm cylinder 2 operates, and its cylinder shaft extends or retracts, driving the two clamping arms 1 to rotate around the mounting base 6, and the post insulator is clamped using the arc clamping surface on the clamping arms 1. Because the gears 3 on the two clamping arms 1 mesh with each other, when one clamping arm 1 rotates, the other clamping arm 1 will rotate in the opposite direction accordingly. The synchronization of the gear transmission ensures that the two clamping arms 1 can synchronously and evenly approach or move away from the post insulator during the clamping process, thus achieving precise and stable clamping action, further improving clamping reliability and processing quality.

[0029] During the post insulator machining process, if the post insulator needs to be rotated for circumferential machining, the two roller cylinders 5 first simultaneously drive the roller assembly 4 toward each other, causing the rollers 41 to clamp the post insulator. Precise control of the roller cylinders 5 ensures that the roller assembly 4 firmly clamps the post insulator while avoiding excessive compression or damage to the post insulator surface.

[0030] The cylinder shaft of the clamping arm cylinder 2 then extends, driving the two clamping arms 1 apart and releasing their grip on the post insulator. At this point, the post insulator is primarily held by the roller assembly 4. The roller 41 in the roller assembly 4 is freely rotatable. When external force is applied to the post insulator, the post insulator easily rotates on the roller 41, achieving circumferential machining. The design of the roller 41 allows the post insulator to be flexibly rotated during machining, meeting machining requirements at various angles and improving the versatility and efficiency of the equipment.

[0031] The two rollers 41 arranged above and below the roller assembly 4 can support and clamp the post insulator from different directions. The multi-point contact method further enhances the stability of the clamping, so that the post insulator will not deviate or shake during the rotation process, ensuring the processing accuracy.

[0032] After processing is complete, the cylinder shaft of the clamping arm cylinder 2 retracts, driving the two clamping arms 1 closer together to re-clamp the post insulator. After the roller assembly 4 releases the post insulator, it provides additional fixed support for the post insulator, facilitating subsequent operations. Simultaneously, the roller cylinder 5 drives the roller assembly 4 in a reverse motion, releasing the grip of roller 41 on the post insulator, allowing the post insulator to be easily removed from the clamping device, completing the entire processing cycle.

[0033] The arc-shaped clamping surface on the clamping arm 1 cooperates with the locking block 11, and the auxiliary clamping of the roller assembly 4 provides a stable and reliable clamping effect for the post insulator. The synchronous transmission of the gear 3 ensures the synchronous movement of the clamping arm 1. The anti-slip teeth effectively prevent the post insulator from slipping during the clamping process, greatly improving the stability and safety of the processing.

[0034] The coordinated operation of the clamping arm cylinder 2 and the roller cylinder 5 automates and maximises the efficiency of clamping, releasing and rotating operations. During processing, clamping modes can be quickly switched to meet the needs of different stages of post insulator processing, reducing manual intervention and improving processing efficiency and quality.

[0035] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
