Description

Technical Field

[0001] This utility model relates to the technical field of appearance inspection equipment, specifically a tooling for sending vacuum circuit breakers for inspection. Background Technology

[0002] Vacuum circuit breakers are widely used in power distribution networks primarily because their arc-extinguishing medium and the insulating medium between the contacts after arc extinguishing are both in high vacuum. Vacuum circuit breakers offer advantages such as small size, light weight, suitability for frequent operation, and maintenance-free arc extinguishing. After production, vacuum circuit breakers undergo performance and visual inspections. Visual inspections include examining the basic structural appearance of the vacuum circuit breaker, as well as the nameplates on the opening / closing handle, energy storage indicator, connection plates, pole markings, aviation connector caps, and electronic tags on the nameplates.

[0003] Existing visual inspection devices for vacuum circuit breakers mainly involve inspecting each vacuum circuit breaker individually, requiring multi-angle adjustments to the vacuum circuit breaker or the visual inspection camera, resulting in low inspection efficiency.

[0004] For example, the aforementioned problem exists in patent (CN119619151A); it describes "a circuit breaker appearance quality inspection system, including an inspection platform, an inspection box, a fixing block, a feeding platform, a CCD camera, a control cylinder, etc.; the inspection box is fixedly connected to the inspection platform, and a feeding platform is installed in front of the inspection platform, located in front of the inspection box. The circuit breaker is fed into the inspection box from the feeding platform. A fixing block is fixedly connected inside the inspection box, and a CCD camera is fixedly connected to both the inspection box and the fixing block. This device uses two CCD cameras..." The machine tests the circuit breaker. Two CCD cameras inspect the circuit breaker from all sides and top and bottom. During the test, the rotating mechanism and the lifting and flipping mechanism can adjust the state of the circuit breaker to quickly test different positions on the outside of the circuit breaker. However, it is necessary to first send the vacuum circuit breaker into the test box and then perform an external inspection on it. Only after one vacuum circuit breaker has been tested and sent out can other vacuum circuit breakers be sent into the test box. The operation is relatively cumbersome and the work efficiency is not high.

[0005] To address the current issues of low efficiency in testing vacuum circuit breakers by individually adjusting each one or the visual inspection camera, we propose a vacuum circuit breaker testing fixture. Utility Model Content

[0026] 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.

[0027] Example 1

[0028] Please see Figures 1-2 and Figures 4-6This utility model provides a technical solution: a vacuum circuit breaker inspection fixture, including an inspection frame 1, an adjusting frame 2, and several clamping frames 3. The inspection frame 1 has symmetrically arranged rotary conveying components 101 on both sides of its inner wall. The adjusting frame 2 is located between two rotary conveying components 101. The adjusting frame 2 includes a rotating base 201. A first cylinder 202 and a second cylinder 203 are vertically and symmetrically arranged on both sides of the top of the rotating base 201. A first insertion plate 204 is hinged to the top of the first cylinder 202 and the second cylinder 203. The bottom center of the clamping frame 3 is provided with a second plug-in plate 301 that matches the first plug-in plate 204; the rotating base 201 includes a support plate 205 and a first servo motor 206. The outer wall of the support plate 205 is provided with an annular rack 207, and the output end of the first servo motor 206 is provided with a gear 208 that meshes with the annular rack 207; the top of the first plug-in plate 204 is provided with a plurality of frustum-shaped protrusions 209, and the bottom of the second plug-in plate 301 is provided with a frustum-shaped groove 302 that matches the frustum-shaped protrusions 209.

[0029] In one embodiment, five frustum-shaped protrusions 209 are provided. One frustum-shaped protrusion 209 is located at the top center of the first insertion plate 204, and the other four frustum-shaped protrusions 209 are evenly distributed in a square on the top of the first insertion plate 204. The center of the inscribed circle of the square distribution structure of the four frustum-shaped protrusions 209 coincides with the top center of the first insertion plate 204. By limiting the number and distribution position of the frustum-shaped protrusions 209, the matching and limiting effect of the frustum-shaped protrusions 209 and the frustum-shaped grooves 302 can be effectively guaranteed, ensuring that the clamping frame 3 can rotate with the adjusting frame 2, while ensuring the stability of the rotation of the clamping frame 3.

[0030] In one embodiment, the rotary conveyor assembly 101 includes a drive roller 102, a driven roller 103, a conveyor belt 104, and a third servo motor 105. The drive roller 102 and the driven roller 103 are rotatably connected to the inspection frame 1. The conveyor belt 104 is movably fitted onto the outer wall of the drive roller 102 and the driven roller 103. The output end of the third servo motor 105 is driven by one end of the drive roller 102. The rotary conveyor assembly 101 adopts a conventional conveyor belt type rotary conveyor. The third servo motor 105 drives the drive roller 102 to rotate. The drive roller 102 and the driven roller 103 cooperate to drive the conveyor belt 104 to rotate, thereby ensuring that the conveyor belt 104 drives the clamping frame 3 to perform horizontal inspection. The two third servo motors 105 need to be synchronously controlled by a synchronous control circuit to ensure that the rotary conveyor assemblies 101 on both sides of the inspection frame 1 perform synchronous conveying work.

[0031] The working principle of this utility model:

[0032] Refer to the instruction manual appendix Figures 1-2 and Figures 4-6 This utility model comprises a test-feeding frame 1, an adjusting frame 2, a clamping frame 3, a rotating base 201, a first cylinder 202, a second cylinder 203, a first connector plate 204, and a second connector plate 301. The clamping frame 3 is used to clamp and fix the vacuum circuit breaker, and the test-feeding frame 1 is used to feed the clamping frame 3 for testing, thereby realizing the testing operation of the vacuum circuit breaker. When the clamping frame 3 moves above the adjusting frame 2 for testing, the adjusting frame 2 can adjust the clamping frame 3, thereby realizing the adjustment operation of the vacuum circuit breaker. The operation is convenient and quick. The appearance inspection equipment for vacuum circuit breakers can be set above the adjusting frame 2. When the clamping frame 3 is transported to the top of the adjusting frame 2, the appearance inspection equipment performs appearance inspection on the vacuum circuit breaker at the top of the clamping frame 3. The rotary conveying component 101 in the inspection frame 1 can realize continuous conveying of the clamping frame 3. It is only necessary to maintain the distance between different clamping frames 3 to avoid contact and collision between different vacuum circuit breakers. It can realize continuous inspection operation of vacuum circuit breakers and effectively improve the inspection and testing efficiency of vacuum circuit breakers.

[0033] The rotating base 201 at the bottom of the adjusting frame 2 can rotate the first cylinder 202 and the second cylinder 203 as a whole, thereby driving the first plug plate 204 to rotate. After the first plug plate 204 and the second plug plate 301 are plugged in, the clamping frame 3 can be rotated to adjust the rotation, thereby realizing the rotation adjustment of the vacuum circuit breaker. This allows the vacuum circuit breaker to rotate during visual inspection, which can effectively improve the efficiency of visual inspection of the vacuum circuit breaker.

[0034] When the first cylinder 202 and the second cylinder 203 are adjusted synchronously for lifting and lowering, the first insertion plate 204 can be driven to move up and down as a whole, thereby realizing the insertion and separation of the first insertion plate 204 and the second insertion plate 301. At the same time, the clamping frame 3 can be pushed up to the position separated from the rotary conveying assembly 101. After the first insertion plate 204 and the second insertion plate 301 are inserted and the clamping frame 3 is separated from the rotary conveying assembly 101, when the first cylinder 202 and the second cylinder 203 are adjusted asynchronously for lifting and lowering, the tilt adjustment of the first insertion plate 204 and the second insertion plate 301 can be realized, thereby realizing the tilt adjustment of the clamping frame 3 and the vacuum circuit breaker. This allows the vacuum circuit breaker to rotate at a tilt angle, which can effectively increase the diversity of appearance inspection of the vacuum circuit breaker, facilitate appearance inspection of specific positions of the vacuum circuit breaker, and effectively improve the inspection accuracy of the vacuum circuit breaker.

[0035] The support plate 205 supports the first cylinder 202 and the second cylinder 203. The first servo motor 206 can drive the gear 208 to rotate. The gear 208 can drive the support plate 205 to rotate through the ring rack 207, thereby driving the rotation of the first cylinder 202, the second cylinder 203 and the first plug-in plate 204.

[0036] The first cylinder 202, the second cylinder 203, the first servo motor 206, and the third servo motor 105 can be controlled by a program to perform specified actions, so that the first cylinder 202, the second cylinder 203, the first servo motor 206, and the third servo motor 105 work according to the specified actions (this can be solved by using existing technology in this field);

[0037] During the docking operation of the first connector 204 and the second connector 301, the frustum-shaped protrusion 209 and the frustum-shaped groove 302 are inserted. Due to the design of the frustum-shaped structure, the frustum-shaped protrusion 209 and the frustum-shaped groove 302 have a guiding function when they are inserted. This allows for automatic alignment even if there is a small deviation between the positions of the first connector 204 and the second connector 301.

[0038] By designing clamping and conveying components corresponding to the vacuum circuit breaker, the vacuum circuit breaker can be fed into the testing area more stably. At the same time, the conveying components can be designed so that the vacuum circuit breaker can complete the designed actions in the testing area, making the testing more comprehensive.

[0039] Example 2

[0040] Please see Figures 1-3 This utility model provides a technical solution: a vacuum circuit breaker inspection fixture, wherein the clamping frame 3 includes a support plate 303, a second plug-in plate 301 is disposed at the bottom center of the support plate 303, and clamping plates 304 are symmetrically and movably connected on both sides of the top of the support plate 303. A reciprocating adjustment mechanism 305 for the clamping plates 304 is provided on the top of the support plate 303. The reciprocating adjustment mechanism 305 includes a second servo motor 306 and a ball screw 307. The ball screw 307 is rotatably disposed on the top of the support plate 303. The thread directions on both sides of the outer wall of the ball screw 307 are opposite. Screw nuts 308 are respectively fitted on both sides of the outer wall of the ball screw 307. The two screw nuts 308 are respectively fixedly connected to the two clamping plates 304. The output end of the second servo motor 306 is connected to one end of the ball screw 307 for transmission.

[0041] In one embodiment, the clamping plate 304 has several sliding plates 309 at its bottom, and a slider 310 at the bottom of each sliding plate 309. The support plate 303 has a guide rail 311 at its top that matches the slider 310. The lead screw nut 308 is fixedly connected to the clamping plate 304 via the sliding plates 309. Several clamping bars 312 are horizontally arranged on the outer wall of the clamping plate 304. The sliding plates 309 provide sliding support at the bottom of the clamping plate 304. The slider 310 and the guide rail 311 cooperate to guide the sliding plates 309, which can effectively improve the stability and safety of the clamping plate 304. When the ball screw 307 drives the lead screw nut 308 to move horizontally for adjustment, the lead screw nut 308 can drive the clamping plate 304 to move horizontally for adjustment via the sliding plates 309, thereby ensuring that the two clamping plates 304 clamp the vacuum circuit breaker.

[0042] The working principle of this utility model:

[0043] Refer to the instruction manual appendix Figures 1-3 This utility model includes a clamping frame 3 comprising a support plate 303, a clamping plate 304, and a reciprocating adjustment mechanism 305. The support plate 303 at the bottom of the clamping frame 3 supports the clamping plate 304 and the second plug-in plate 301. In use, the vacuum circuit breaker to be tested is placed between the two clamping plates 304, and the reciprocating adjustment mechanism 305 drives the two clamping plates 304 to clamp, fix, and release the vacuum circuit breaker. The clamping frame 3 is independently designed, and multiple clamping frames 3 can be placed on the test rack 1 at the same time. It is only necessary to maintain the distance between different clamping frames 3 to avoid contact and collision between different vacuum circuit breakers, thereby ensuring continuous feeding and inspection of vacuum circuit breakers.

[0044] When the reciprocating adjustment mechanism 305 is working, the second servo motor 306 drives the ball screw 307 to rotate. Since the threads on both sides of the outer wall of the ball screw 307 are opposite, when the ball screw 307 rotates, the ball screw 307 can drive the two screw nuts 308 to move synchronously. The two screw nuts 308 move in opposite directions, so that the two clamping plates 304 can move towards the center of the ball screw 307 at the same time or towards both ends of the ball screw 307 at the same time, ensuring the clamping and loosening operation of the vacuum circuit breaker by the two clamping plates 304.

[0045] By arranging displacement sensors or force sensors between the two clamping plates 304, the second servo motor 306 is controlled to stop working after the two clamping plates 304 clamp the vacuum circuit breaker, so as to avoid damage to the vacuum circuit breaker clamping (the above control method can be solved by existing technical means in this field, or other control methods can be used).

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
