Description

Technical Field

[0001] The utility model relates to the field of positioning moulds, in particular to a vacuum arc extinguishing chamber assembly positioning mould. Background Art

[0002] Chinese utility model patent application number: CN201520341656.X, a vacuum arc chamber is proposed, aiming to provide a vacuum arc chamber capable of ensuring sealing, the key points of its technical solution are comprising a top cover and a ceramic insulating shell, the top cover is provided with a convex ring, the ceramic insulating shell is provided with a groove matching the convex ring, the groove is provided with a sealing mechanism, the sealing mechanism includes a sealing ring abutting against the outer side wall of the convex ring, the ceramic insulating shell is provided with a fixing groove for the sealing ring to be inserted and fixed, in the assembly and manufacturing process of the vacuum arc chamber, the positioning mold plays a key role, it is used to determine the positional relationship of the parts when they are stacked and assembled.

[0003] However, there are some shortcomings in the existing vacuum interrupter during the assembly process that still need to be improved. The existing mold lacks a clear initial positioning reference, which leads to a large degree of randomness in the placement of the vacuum interrupter components to be assembled. This makes it easy for the initial position of the components to deviate, which in turn causes a series of assembly errors in the subsequent assembly process, affecting the assembly accuracy of the entire vacuum interrupter. During the assembly process, the existing mold cannot achieve precise positioning between the various components and cannot ensure that the various components are in precise relative positions. This will result in low matching accuracy between the various components of the vacuum interrupter, affecting its performance and quality.

[0004] The existing mold lacks effective guiding and supporting structures during the movement of the lower mold and the pressure plate. This makes them prone to displacement and shaking during movement, resulting in the inability of the positioning punch and the positioning die to accurately match, further reducing the assembly accuracy. The existing mold cannot effectively fix and limit the vacuum interrupter components from multiple directions. The components are prone to displacement during the assembly process, resulting in an unsmooth assembly process and even component damage. Therefore, we have made improvements to this and proposed a vacuum interrupter assembly positioning mold. Utility Model Content

[0014] Compared with the prior art, the utility model has the following beneficial effects: the positioning angle grooves and the positioning pins embedded therein provided at the four corners of the lower die base of the utility model provide accurate initial positioning references for the vacuum arc chamber components to be assembled. This design can ensure that the components are in precise positions when placed, reducing assembly errors caused by initial position deviations. The lower die cavity and the center hole of the die inside the positioning die of the utility model precisely match the positioning punch under the pressure plate.

[0015] The mold guide rods embedded on both sides of the lower fixed plate of the utility model play a good guiding and supporting role in the movement of the lower mold and the pressing plate. It ensures that the lower mold and the pressing plate move stably along a straight line, avoids deviation and shaking during the movement, further improves the accuracy of the positioning punch and the positioning die, and thus improves the assembly quality.

[0016] The L-shaped fixed side plate of the lower mold welded to one side of the lower mold base of the utility model, and the angle iron positioning block installed on the top edge of the lower mold base, can fix and limit the vacuum arc chamber components from multiple directions.

[0018] The utility model adopts a linkage structure design. Through the coordinated work of the linkage block, the mold folding rod and the punch connecting rod, the linear motion of the assembly telescopic rod is converted into the precise movement of the pressing plate and the positioning punch. This linkage design enables the various parts of the mold to cooperate efficiently, reduces manual intervention and operation steps, and further improves assembly efficiency.

[0019] The mold spring connected to the center end below the fixed plate of the utility model plays a buffering role during the assembly process. When the positioning punch contacts the positioning die, the mold spring can absorb a certain impact force to avoid damage to the mold and vacuum interrupter components due to excessive impact force, thereby extending the service life of the mold and components. The guiding function of the mold guide rod not only ensures the movement accuracy, but also protects the mold components to a certain extent. It can prevent the lower mold and the pressure plate from colliding and rubbing with other components during movement, reduce the wear of the components, and improve the reliability and stability of the mold.

It should be noted that similar numbers and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0030] Example 1: Please refer to Figure 1-Figure 6A vacuum arc extinguishing chamber assembly positioning mold comprises a base 1, a lower mold base 2 is installed at the center end above the base 1, a lower mold L-shaped fixed side plate 3 is welded to one side of the lower mold base 2, positioning angle grooves 4 are arranged at the four corners of the lower mold base 2, a slot hole 41 is opened at the center of the positioning angle groove 4, a positioning pin 5 is arranged in the slot hole 41, a positioning die 6 is fixed above the lower mold base 2, a lower mold cavity 7 is arranged inside the positioning die 6, and the center of the lower mold cavity 7 is connected to the center hole 8 of the die.

[0031] An angle iron positioning block 9 is installed on the top edge of the lower die base 2. A buffer pad 10 is fixed below the base 1, and there are four buffer pads 10, which are linearly installed at the four corners of the bottom of the base 1. Support side frames 11 are inlaid on both sides above the base 1, and upper frames 12 are bolted above the two plates of the support side frames 11.

[0032] An assembly hydraulic cylinder 13 is installed above the upper frame 12, and an assembly telescopic rod 14 is slidably connected inside the assembly hydraulic cylinder 13. A fixed plate 15 is installed below the upper frame 12, and a mold spring 16 is connected to the center end below the fixed plate 15, and mold guide rods 17 are embedded on both sides.

[0033] A linkage block 18 is provided between the two rods of the mold guide rod 17, and the top of the linkage block 18 is connected to the bottom of the assembly telescopic rod 14, and a mold folding rod 19 is installed on the rotating shaft of the linkage part of the linkage block 18. A lower mold 20 is installed on the bottom rod of the mold guide rod 17, and a pressing plate 21 is provided below the lower mold 20. A punch connecting rod 22 is embedded in the U groove at the front end of the pressing plate 21, and the top end of the punch connecting rod 22 is connected to the mold folding rod 19.

[0034] A positioning punch 23 is provided at the center end below the pressure plate 21, and the punch connecting rod 22 is installed with the positioning punch 23 through a connecting rod. The main function of the vacuum interrupter assembly positioning mold is to achieve accurate assembly and positioning of the vacuum interrupter. It uses the assembly hydraulic cylinder 13 to provide power through the cooperation of the lower die base 2 and the upper frame 12 and other components, combined with the linkage structure such as the die spring 16, the die guide rod 17, and the die folding rod 19, so that the positioning punch 23 and the positioning die 6 are accurately docked to complete the assembly and positioning of the vacuum interrupter.

[0035] The specific working principle of the utility model is as follows: the mold is placed on a working plane, and the four cushions 10 under the base 1 play a role of buffering and stable support. The cushions 10 can reduce the impact force between the mold and the ground during the working process, prevent the vibration from affecting the assembly accuracy, and also ensure the stability of the mold placement, making the entire assembly process more reliable.

[0036] The lower die base 2 is installed at the center end above the base 1, and the lower die L-shaped fixed side plate 3 on one side is used to assist in fixing and positioning related components. The positioning angle grooves 4 at the four corners of the lower die base 2 and the positioning pins 5 embedded therein provide precise positioning references for the subsequent placement of the vacuum arc chamber components to be assembled, ensuring the accuracy of component placement. The positioning die 6 is fixed above the lower die base 2, and the lower die cavity 7 and the die center hole 8 inside it are key structures for placing specific parts of the vacuum arc chamber, providing accurate spatial positions for assembly. The angle iron positioning block 9 on the top edge of the lower die base 2 further positions and limits the components to improve the accuracy and stability of assembly.

[0037] When the assembly operation is required, the assembly hydraulic cylinder 13 is started. The assembly hydraulic cylinder 13 is the power source of the entire mold, which converts hydraulic energy into mechanical energy. The assembly telescopic rod 14 slides inside the assembly hydraulic cylinder 13. As the hydraulic oil is injected or discharged, the assembly telescopic rod 14 moves up and down. The movement of the assembly telescopic rod 14 will provide power for the subsequent mold linkage and drive the entire assembly process. When the assembly telescopic rod 14 moves downward, the linkage block 18 connected to the bottom of the assembly telescopic rod 14 also moves downward. The movement of the linkage block 18 drives the mold folding rod 19 installed with the rotating shaft to move. The rotation of the mold folding rod 19 will produce force transmission and change of direction, thereby achieving a linkage effect. At the same time, the mold guide rods 17 embedded on both sides below the fixed plate 15 play a guiding and supporting role. The mold guide rods 17 ensure the linearity and stability of the lower mold 20 and the pressure plate 21 during the movement process, prevent deviation or shaking during the movement process, and ensure the accuracy of assembly. The mold spring 16 is installed at the center end below the fixed plate 15, and plays a buffering and resetting role during the movement. When the assembly telescopic rod 14 moves downward, the mold spring 16 will be compressed to store a certain amount of elastic potential energy; when the assembly is completed, the elastic potential energy of the spring is released to help the mold components to reset.

[0038] The movement of the mold folding rod 19 is transmitted to the pressing plate 21 through the punch connecting rod 22. Since the top of the punch connecting rod 22 is connected to the mold folding rod 19 and the bottom is embedded in the U groove at the front end of the pressing plate 21, when the mold folding rod 19 rotates, the punch connecting rod 22 will drive the pressing plate 21 to move downward.

[0039] The positioning convex mold 23 provided at the center end below the pressing plate 21 moves downward as the pressing plate 21 descends. The positioning convex mold 23 cooperates with the positioning concave mold 6, and the positioning convex mold 23 is accurately inserted into the lower mold cavity 7 and the center hole 8 of the concave mold 6. Through this precise cooperation, the assembly positioning of the vacuum interrupter components is realized, and each component is accurately installed at a predetermined position.

[0040] When the assembly is completed, the assembly hydraulic cylinder 13 controls the assembly telescopic rod 14 to move upward. As the assembly telescopic rod 14 rises, the linkage block 18, the mold folding rod 19, the punch connecting rod 22 and other components are reset in sequence. At the same time, the elastic potential energy of the mold spring 16 is released, assisting the lower mold 20 and the pressing plate 21 to move upward and return to the initial position, ready for the next assembly operation.

[0041] Embodiment 2: A vacuum arc chamber assembly positioning mold, select a flat and solid ground, and place the base 1 with four buffer pads 10 on the ground. The buffer pads 10 can play a role in buffering and shock absorption to ensure the stability of the mold during operation. Check whether the buffer pads 10 are evenly stressed. If necessary, adjust the flatness of the ground or replace the buffer pads to ensure that the base 1 is in a horizontal state.

[0042] Install the lower die base 2 on the upper center end of the base 1 to ensure that it is firmly installed. Next, weld the lower die L-shaped fixed side plate 3 to one side of the lower die base 2 to ensure the welding quality so that it can stably fix the vacuum interrupter components. Insert the positioning pin 5 into the positioning angle groove 4, check the embedding depth and stability of the positioning pin 5 to ensure that it can provide an accurate initial positioning reference for the vacuum interrupter components to be assembled.

[0043] Fix the positioning die 6 above the lower die base 2 to ensure that the lower die cavity 7 and the die center hole 8 inside the positioning die 6 are positioned accurately. At the same time, install the angle iron positioning block 9 on the top edge of the lower die base 2 so that it can fix and limit the vacuum interrupter components from multiple directions.

[0044] The supporting side frames 11 are embedded on both sides above the base 1 to ensure the verticality of the installation of the supporting side frames 11. Then, the upper frame 12 is fixed on the two plates of the supporting side frames 11 with bolts to ensure a firm connection.

[0045] Install the assembly hydraulic cylinder 13 above the upper frame 12, and ensure that its installation position is accurate so as to provide stable power for the assembly action of the mold. Install the assembly telescopic rod 14 inside the assembly hydraulic cylinder 13 and check its smoothness of sliding.

[0046] Install the fixed plate 15 below the upper frame 12, connect the mold spring 16 to the center end below the fixed plate 15, and embed the mold guide rods 17 on both sides. Check the elasticity and installation position of the mold spring 16 to ensure that it can play a buffering role during the assembly process; check the installation verticality and sliding smoothness of the mold guide rod 17 to ensure that it can play a good guiding and supporting role during the movement of the lower mold 20 and the pressure plate 21.

[0047] A linkage block 18 is installed between the two rods of the mold guide rod 17, and its top is connected to the bottom of the assembly telescopic rod 14. The mold folding rod 19 rotating shaft is installed on the linkage part of the linkage block 18 to ensure that the linkage block 18 and the mold folding rod 19 can move flexibly. A pressing plate 21 is set below the lower mold 20, and the punch connecting rod 22 is embedded in the U groove at the front end of the pressing plate 21, and its top end is connected to the mold folding rod 19. Finally, the positioning punch 23 is installed at the lower center end of the pressing plate 21, and the punch connecting rod 22 is connected to the positioning punch 23 through a connecting rod to ensure that the entire linkage structure can work together.

[0048] After all parts are installed, debug the mold. Start the assembly hydraulic cylinder 13, observe the up and down movement of the assembly telescopic rod 14, and check whether the linkage block 18, mold folding rod 19, punch connecting rod 22 and positioning punch 23 can move accurately according to the design requirements. Adjust the position and connection of each component to ensure that the positioning punch 23 can be accurately inserted into the lower mold cavity 7 and the center hole 8 of the positioning die 6 to achieve accurate positioning of the vacuum interrupter components.

[0049] The workflow of vacuum arc chamber assembly and positioning mold: Place the mold as a whole on a suitable working plane, and use the four buffer pads 10 at the four corners below the base 1 to play a buffering and stable support role to ensure that the mold is placed stably. Preliminarily position the vacuum arc chamber related components to be assembled according to the positioning pins 5 in the positioning angle grooves 4 at the four corners of the lower die base 2, and place them on the lower die base 2. At the same time, use the angle iron positioning block 9 on the top edge of the lower die base 2 to further limit and accurately adjust the position of the components, so that the components are accurately located at the appropriate position above the positioning die 6. The lower die L-shaped fixed side plate 3 assists in fixing and positioning related components to ensure that the components are placed stably.

[0050] The assembly hydraulic cylinder 13 is turned on, and the hydraulic system starts to work, so that the assembly telescopic rod 14 starts to slide downward inside the assembly hydraulic cylinder 13. The downward movement of the assembly telescopic rod 14 provides power for the subsequent mold linkage.

[0051] As the assembly telescopic rod 14 moves downward, the linkage block 18 connected to the bottom thereof moves downward synchronously. The downward movement of the linkage block 18 drives the mold folding rod 19 installed on the rotating shaft of its linkage part to rotate. The mold guide rods 17 embedded on both sides of the lower side of the fixed plate 15 play a guiding and supporting role, ensuring that the lower mold 20 and the pressing plate 21 move stably along a straight line during the movement. At the same time, the mold spring 16 at the center end of the lower side of the fixed plate 15 begins to be compressed to store elastic potential energy.

[0052] The rotation of the mold folding rod 19 is transmitted to the pressing plate 21 through the punch connecting rod 22. Since the top of the punch connecting rod 22 is connected to the mold folding rod 19, and the bottom is embedded in the U groove at the front end of the pressing plate 21, the mold folding rod 19 drives the pressing plate 21 to move downward when it rotates. The positioning punch 23 at the center end below the pressing plate 21 moves downward as the pressing plate 21 descends, and finally the positioning punch 23 is accurately inserted into the lower mold cavity 7 and the center hole 8 of the positioning die 6, so as to realize the precise assembly and positioning of the vacuum interrupter components.

[0053] After the assembly positioning is completed, the assembly hydraulic cylinder 13 is controlled to make the assembly telescopic rod 14 slide upward.

[0054] The upward movement of the assembly telescopic rod 14 drives the linkage block 18 to move upward, and the linkage block 18 drives the mold folding rod 19 to rotate in the opposite direction and reset. The compressed mold spring 16 releases elastic potential energy, assisting the lower mold 20 and the pressing plate 21 to move upward along the mold guide rod 17 and return to the initial position. At the same time, the punch connecting rod 22 is also reset with the movement of the mold folding rod 19 and the pressing plate 21, ready for the next assembly operation. When the mold parts are reset, the finished vacuum interrupter that has been assembled and positioned is taken out of the mold, completing the entire assembly process.

[0055] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods.
