Description

Technical Field

[0001] This utility model belongs to the field of vacuum interrupter manufacturing, and in particular relates to a vacuum interrupter production system and vacuum interrupter assembly and testing equipment. Background Technology

[0002] The vacuum interrupter is the core component of a vacuum circuit breaker. To ensure excellent arc-extinguishing performance, the coaxiality of the vacuum interrupter must be guaranteed during assembly.

[0003] Chinese utility model patent with authorization announcement number CN217588739U and authorization announcement date of October 14, 2022 discloses a support device for assembling a vacuum interrupter. The support device includes a worktable, a support frame, a rotary table, a coaxial instrument (equivalent to a testing device), and a base. The worktable is provided with multiple pillars, and the support frame is movably mounted on the pillars. The support frame has a through hole that runs through the support frame in the vertical direction. The rotary table is located below the through hole, and a part of the base passes through the through hole and engages with the rotary table to prevent rotation, so that the rotary table can drive the base to rotate.

[0004] When using the aforementioned support device to produce a vacuum interrupter, firstly, the base needs to be placed on a rotary table; then, the vacuum interrupter needs to be assembled on the base. During the assembly process, the rotary table drives the vacuum interrupter to rotate, and a coaxiality meter is used to check the coaxiality of the vacuum interrupter, thereby ensuring the assembly quality of the vacuum interrupter; finally, a forklift arm is used to send the support frame, base, and vacuum interrupter together into the vacuum brazing furnace.

[0005] In the above process, on the one hand, when the forklift arm is raised and lowered, oil stains easily accumulate on the forklift arm, which can then adhere to the support frame. During welding, the oil stains on the support frame will evaporate in the vacuum brazing furnace, affecting the quality of the vacuum interrupter. On the other hand, using a forklift to transport the support frame, base, and vacuum interrupter is cumbersome and affects production efficiency.

[0006] After the vacuum interrupter is welded, its coaxiality needs to be checked again to ensure that the welded vacuum interrupter has excellent arc-extinguishing performance. The aforementioned patent document does not specify how to check the coaxiality of the vacuum interrupter again. The following is a possible method: Use a forklift to place the support frame, base, and vacuum interrupter back onto the workbench, and then use a coaxiality meter to check the coaxiality of the vacuum interrupter again. Utility Model Content

[0007] The purpose of this invention is to provide a vacuum interrupter production system to solve the technical problems of the cumbersome transportation of vacuum interrupters using forklifts, which affects production efficiency and causes oil stains to adhere to the support frame, affecting the quality of the vacuum interrupters.

[0008] The purpose of this utility model is also to provide a vacuum interrupter assembly and testing device to solve the same technical problems mentioned above.

[0009] To achieve the above objectives, the technical solution of the vacuum interrupter production system provided by this utility model is as follows:

[0010] A vacuum interrupter production system includes a vacuum brazing furnace, a welding furnace frame, and vacuum interrupter assembly and testing equipment. The vacuum interrupter assembly and testing equipment includes a rotary table, a transfer mechanism for transferring the welding furnace frame, and a testing device for measuring the coaxiality of the vacuum interrupter. The welding furnace frame has a vertical through hole for the upper end of the rotary table to pass through. The transfer mechanism includes a horizontal drive mechanism for driving the welding furnace frame to move horizontally and a vertical drive mechanism for driving the horizontal drive mechanism to move vertically. The transfer mechanism has a testing station for allowing the rotary table to pass through the vertical through hole and engage with the vacuum interrupter to prevent rotation; a transfer station located directly above the testing station and where the welding furnace frame is also located directly above the rotary table; a welding station for contacting the welding furnace frame with both the furnace bed and the horizontal drive mechanism of the vacuum brazing furnace; and a disengagement station located directly below the welding station and where the welding furnace frame is separated from the horizontal drive mechanism.

[0011] Furthermore, a rotational power source for driving the rotary table to rotate at a constant speed is provided directly below the rotary table.

[0012] Furthermore, the vacuum interrupter assembly and testing equipment is located on the right side of the vacuum brazing furnace, and the horizontal drive mechanism is a direct drive mechanism whose output end can move in the left and right directions.

[0013] Furthermore, the direct drive mechanism includes a direct power source and a support plate that is connected to the direct power source for transmission.

The support plate constitutes the output end.

[0014] Furthermore, the rotary table includes a large-diameter section and a small-diameter section located above the large-diameter section.

This convenient transfer improves production efficiency. Furthermore, since no forklift is needed, it avoids oil stains from the forklift arms adhering to the welding furnace frame, thus improving welding quality.

During the rotation of the vacuum interrupter, the coaxiality of the vacuum interrupter before welding is checked by the inspection device to ensure the assembly quality of the vacuum interrupter.

[0018] Step S2: After assembly, switch the transfer mechanism sequentially to the transfer station, welding station and unloading station;

[0049] To address the problems in the background technology, the core inventive concept of this utility model is as follows: Vacuum interrupter assembly and testing equipment is used to test both the vacuum interrupter before welding and the vacuum interrupter after welding. The vacuum interrupter assembly and testing equipment is placed near the vacuum brazing furnace. Simultaneously, a transfer mechanism is used to transfer the welding furnace frame carrying the vacuum interrupter, thereby improving the production efficiency of the vacuum interrupter.

[0050] The present invention will be further described in detail below with reference to the embodiments.

[0051] Specific embodiments of the vacuum interrupter production system provided by this utility model:

[0052] like Figures 1-10 As shown in the basic embodiment, the vacuum interrupter production system includes a vacuum brazing furnace 1, a welding furnace frame 2, and a vacuum interrupter assembly and testing equipment 3. The vacuum interrupter assembly and testing equipment 3 includes a rotary table 35, a transfer mechanism for transferring the welding furnace frame 2, and a testing device for measuring the coaxiality of the vacuum interrupter. The welding furnace frame 2 is provided with a vertical through hole 21 for the upper end of the rotary table 35 to pass through. The transfer mechanism includes a horizontal drive mechanism 36 for driving the welding furnace frame 2 to move horizontally and a vertical drive mechanism 32 for driving the horizontal drive mechanism 36 to move up and down. The transfer mechanism has a testing station for the rotary table 35 to pass through the vertical through hole 21 and cooperate with the vacuum interrupter to prevent rotation, a transfer station located directly above the testing station and the welding furnace frame 2 is also located directly above the rotary table 35, a welding station for the welding furnace frame 2 to contact the furnace bed 11 of the vacuum brazing furnace 1 and the horizontal drive mechanism 36, and a separation station located directly below the welding station and separating the welding furnace frame 2 from the horizontal drive mechanism 36.

[0053] Preferably, in one specific embodiment, the testing device includes a bracket 38 and a circular runout tolerance measuring instrument 37 mounted on the bracket 38. The circular runout tolerance measuring instrument 37 can measure the runout of the vacuum interrupter surface. If the runout of the vacuum interrupter surface is 0 when the vacuum interrupter rotates, it proves that the coaxiality of the vacuum interrupter is qualified.

[0054] Of course, in other specific embodiments, the detection device may also be a photoelectric displacement sensor or a coaxial instrument, etc.

[0055] like Figures 1-10 As shown, in one specific embodiment, there are four vertical perforations 21 and four rotating platforms 35, thus accommodating different vacuum interrupters. It should be specifically noted that when a rotating platform 35 drives a single vacuum interrupter to rotate, only one rotating platform 35 engages with that vacuum interrupter to prevent rotation. Simultaneously, this rotating platform 35 rotates on its own axis, and the axis of rotation of this rotating platform 35 coincides with the axis of rotation of the vacuum interrupter (i.e., the vacuum interrupter also rotates). The other three rotating platforms 35 and the welding furnace frame 2 do not rotate. After one rotating platform 35 drives a vacuum interrupter to rotate, the next rotating platform 35 can engage with the vacuum interrupter to prevent rotation, thereby allowing the next rotating platform 35 to drive the vacuum interrupter to rotate.

[0056] Of course, the number of rotary stages 35 can be one, two or other, depending on the specific structure of the vacuum interrupter to be measured, which will not be elaborated here.

[0057] In different specific embodiments, one, two, three, four, or more vacuum interrupters can be assembled simultaneously. For example, when a vacuum interrupter structure only requires one rotary table 35, in Figures 1-10 In the specific embodiment shown, four vacuum interrupters can be assembled simultaneously using four rotary tables 35, which helps to improve production efficiency.

[0058] Compared to existing technologies, the main difference between this invention and existing technologies lies in the following: the vacuum interrupter assembly and testing equipment 3 has a transfer mechanism, which can transfer the welding furnace frame 2 carrying the vacuum interrupter to the vacuum brazing furnace 1, and can also transfer the welding furnace frame 2 inside the vacuum brazing furnace 1 to the rotary table 35. This convenient transfer facilitates production efficiency. Furthermore, since a forklift is not required, oil stains from the forklift arms can be avoided from adhering to the welding furnace frame 2, thus improving welding quality.

[0059] When using the vacuum interrupter production system of this utility model to produce vacuum interrupters, the following steps can be followed:

[0060] Step S1, as follows Figure 5As shown, the transfer mechanism is switched to the inspection station, and the vacuum interrupter is assembled. During the assembly process, the rotary table 35 rotates. Since the rotary table 35 has a vertical through-hole 21 and is fitted with the vacuum interrupter to prevent rotation, the rotary table 35 can drive the vacuum interrupter to rotate (at this time, the welding furnace frame 2 is not in contact with the vacuum interrupter). During the rotation of the vacuum interrupter, the coaxiality of the vacuum interrupter before welding is checked by the inspection device to ensure the assembly quality of the vacuum interrupter.

[0061] Step S2, refer to Figures 6-8 After assembly, the transfer mechanism is switched sequentially to the transfer station, welding station and unloading station.

[0062] Specifically, firstly, the vertical drive mechanism 32 drives the welding furnace frame 2 and the horizontal drive mechanism 36 to rise until the transfer mechanism switches to the intermediate station; then, the horizontal drive mechanism 36 drives the welding furnace frame 2 closer to the vacuum brazing furnace 1, and at the same time, it can be decided whether to use the vertical drive mechanism 32 to adjust the height of the welding furnace frame 2 until the transfer mechanism switches to the welding station; then, the vertical drive mechanism 32 drives the horizontal drive mechanism 36 to descend, at which point the transfer mechanism switches to the disengagement station.

[0063] Step S3: Remove the transfer mechanism from the vacuum brazing furnace 1;

[0064] Step S4: Turn on the vacuum brazing furnace 1 to complete the welding work in the vacuum arc-extinguishing chamber;

[0065] Step S5, refer to Figures 5-8 This allows the transfer mechanism to sequentially switch to the departure station, welding station, transfer station, and inspection station;

[0066] Step S6: Rotate the rotary table 35 again. The rotary table 35 will drive the vacuum interrupter to rotate again, and the coaxiality of the vacuum interrupter after welding will be detected by the detection device.

[0067] Preferably, such as Figures 3-9 As shown, in one specific embodiment, a rotary power source for driving the rotary table 35 to rotate at a constant speed is provided directly below the rotary table 35. The rotary power source can be a commonly used rotary power source such as a rotary motor 34 or a rotary cylinder.

[0068] Of course, in other specific embodiments, referring to the Chinese utility model patent with authorization announcement number CN217588739U, the rotary table 35 may not be equipped with a power source, and the operator needs to manually make the rotary table 35 rotate.

[0069] To facilitate understanding by those skilled in the art, the following description will be based on an example of a vacuum interrupter consisting of an upper and a lower section:

[0070] Compared to the technical solution of manually rotating the rotary table 35, driving the rotary table 35 to rotate at a constant speed by a rotary power source can better ensure the coaxiality of the vacuum interrupter.

[0071] Specifically, when the operator manually rotates the rotary table 35, the rotation speed of the rotary table 35 fluctuates, which causes all parts to tend to move horizontally. Since the lower part is engaged with the rotary table 35 to prevent rotation, while the upper part is not engaged with other structures to prevent rotation, relative movement occurs between the upper and lower parts each time the operator rotates the rotary table 35. This results in a decrease in the coaxiality of the vacuum interrupter and affects the assembly efficiency.

[0072] When the rotary power source drives the rotary table 35 to rotate at a constant speed, there will be no relative motion between the upper and lower parts, thereby improving assembly efficiency.

[0073] To simplify the structure, such as Figures 1-10 As shown, in one specific embodiment, the vacuum interrupter assembly and testing equipment 3 is set on the right side of the vacuum brazing furnace 1. The horizontal drive mechanism 36 is a direct drive mechanism whose output end can move in the left and right directions. At this time, the transfer mechanism only forms a two-degree-of-freedom (up and down and left and right directions) transfer mechanism, which has a simple structure.

[0074] However, in other specific embodiments, the horizontal drive mechanism 36 may also include a left-right drive mechanism and a front-back drive mechanism, with one of the left-right drive mechanism and the front-back drive mechanism located at the output end of the other, so that the transfer mechanism forms a three-degree-of-freedom (front-back direction, left-right direction and up-down direction) transfer mechanism.

[0075] Preferably, such as Figures 1-10 As shown, in one specific embodiment, the direct drive mechanism includes a direct power source and a support plate 361 that is connected to the direct power source for transmission. The support plate 361 is used to support the welding furnace frame 2, and the support plate 361 is provided with a clearance hole 362 for avoiding the rotary table 35. One of the support plate 361 and the vertical drive mechanism 32 has a slide rail extending in the left-right direction, and the other has a sliding part that slides in cooperation with the guide of the slide rail. The support plate 361 constitutes the output end.

[0076] The direct-acting power source can be a direct-acting motor, an electric telescopic rod, or a direct-acting cylinder, etc.; the vertical drive mechanism 32 includes a vertical power source and a guide member that is connected to the vertical power source for transmission. The guide member is a structure such as a guide plate or a guide block, and the vertical power source is a direct-acting motor, a direct-acting telescopic rod, etc., whose output end can move in the vertical direction. The edge portions at both ends of the support plate 361 constitute sliding parts, and the guide member is provided with slide rails; of course, sliders can also be provided on the guide member, and slide rails can be provided on the front and rear sections of the support plate 361.

[0077] like Figures 1-10 As shown, in one specific embodiment, the transfer mechanism further includes a base 31, a vertical drive mechanism 32 mounted on the base 31, and the base 31 and the vertical drive mechanism 32 having a relatively long length in the left-right direction. A self-rotating module is formed by a rotary motor 34, a rotary table 35, and a support platform 33 for supporting the rotary motor 34. The self-rotating module is located in the left half of the base 31, and the right half of the base 31 forms a material preparation area 39 for temporarily placing the raw materials and assembly tools for the vacuum interrupter assembly.

[0078] In reference Figures 1-6 On the basis of, such as Figures 7-8 As shown, when the transfer mechanism is in the welding position, the left end of the pallet 361 extends a long distance. At this time, the sliding part and the slide rail are still guided and matched, so that the vertical drive mechanism 32 can still support the pallet 361 and reduce the deflection force on the direct power source in the horizontal drive mechanism 36.

[0079] Of course, in other specific embodiments, the horizontal drive mechanism 36 can also be two electric telescopic rods installed on the top of the vertical drive mechanism 32. The telescopic ends of the two electric telescopic rods are connected to support plates. The two support plates are arranged at intervals, and the gap between the two support plates forms a clearance space for avoiding the rotary table 35. The welding furnace frame 2 can be placed on the two support plates at the same time.

[0080] Of course, the support plate can also be replaced with support blocks, support cylinders or other support structures, and the electric telescopic rod can also be replaced with a direct-drive motor, direct-drive hydraulic cylinder or other direct-drive power source.

[0081] To better ensure welding quality and reduce the workload of workers, Figure 9 In the specific embodiment shown, the rotary table 35 includes a large-diameter section 351 and a small-diameter section 352 located above the large-diameter section 351. During the production of the vacuum interrupter, workers only need to wipe the upper surfaces of the small-diameter section 352 and the large-diameter section 351 clean to prevent oil stains from adhering to the vacuum interrupter.

[0082] In other specific embodiments, the diameter of the rotary table 35 is always the same. In this case, the staff needs to wipe the rotary table 35 clean to avoid oil stains adhering to the vacuum interrupter.

[0083] In this invention, preferably, the surface of the horizontal drive mechanism 36 is covered with replaceable padding material. When the padding material becomes contaminated with oil, it can be replaced directly, thus preventing oil contamination on the welding furnace frame 2. Of course, the oil can also be wiped off manually.

[0084] Specific embodiments of the vacuum interrupter assembly and testing equipment provided by this utility model:

[0085] Reference Figures 1-10 As shown, the main difference between the vacuum interrupter production system and the vacuum interrupter assembly and testing equipment 3 in this utility model is that the vacuum interrupter production system includes a vacuum brazing furnace 1 and a welding furnace frame 2, while the vacuum interrupter assembly and testing equipment 3 does not include the vacuum brazing furnace 1 and the welding furnace frame 2.

[0086] In this utility model, the specific structure of the vacuum interrupter assembly and testing equipment 3 is the same as that of any specific embodiment of the vacuum interrupter production system provided by this utility model, and will not be described again here.

[0087] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present 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 without creative effort, or make equivalent substitutions for some of the technical features, or organically combine different types of specific implementation methods to create appendices. Figures 1-10 The specific embodiments described herein are provided, but those skilled in the art can certainly devise other specific embodiments not shown in the accompanying drawings. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
