Description

Technical Field

[0001] The invention belongs to the technical field of tooling and relates to an out-of-mold assembly tooling for a solid insulating cylinder. Background Art

[0002] In a solid switch cabinet, a solid insulating cylinder is usually used to insulate each conductive component from the external environment. Therefore, the performance of the solid insulating cylinder directly affects the safety and reliability of the power transmission and distribution system. The solid insulating cylinder includes a cylinder made of insulating material and a conductive component and a metal shielding component embedded in the cylinder. The conductive component generally includes an incoming conductive rod, an outgoing conductive rod and a vacuum switch tube (also called a vacuum arc extinguishing chamber). The outgoing conductive rod is L-shaped. The horizontal section of the outgoing conductive rod and the upper end of the vacuum switch tube, i.e., the static end, are fixed by fasteners to conduct electricity. At the same time, the switch assembly is used to realize power on or off between the incoming conductive rod and the lower end, i.e., the moving end, of the vacuum switch tube. The metal shielding component is mainly arranged at the connection of the conductive components inside the solid insulating cylinder to play a role in uniform internal electric field, such as a bowl-shaped metal shielding cover arranged outside the end of the horizontal section of the outgoing conductive rod and a metal shielding ring sleeved outside the vertical section of the outgoing conductive rod. For details, please refer to the solid insulating cylinder disclosed in the application number 202011010680.7.

[0003] The cylinder of the solid insulating cylinder is formed by epoxy casting. Before casting, the conductive components and metal shielding components are placed at the corresponding positions of the mold, and then the cylinder is cast into the mold to form the cylinder, so that the conductive components and metal shielding components are embedded in the cylinder at the same time. Among them, the vacuum switch tube and the outgoing line conductive rod, as well as the outgoing line conductive rod and the bowl-shaped metal shielding cover, need to be assembled together before being placed in the mold as a whole. In particular, it is also necessary to fix a protective head at the moving end of the vacuum switch tube, fix a protective cover at the end of the vertical section of the outgoing line conductive rod, and put the metal shielding ring on the vertical section of the outgoing line conductive rod. At present, the vacuum switch tube and the outgoing line conductive rod are directly connected by the staff holding them. The connection process not only requires a long alignment time, resulting in low efficiency; the verticality and parallelism are judged by the naked eye of the staff, resulting in low assembly accuracy and directly affecting the quality of the product. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems existing in the prior art and to propose an out-of-mold assembly tool for a solid insulating cylinder, thereby solving the problems of poor assembly accuracy and low assembly efficiency.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] An out-of-mold assembly tool for a solid insulating cylinder comprises a frame and a positioning seat arranged on the frame, characterized in that the frame is provided with a limit seat lower than the positioning seat and a sliding seat located below the positioning seat and capable of sliding upward, the positioning seat is provided with guide holes penetrating at both ends in the vertical direction, the limit seat has an inner hole parallel to the guide hole, a positioning groove is provided on the upper side of the positioning seat, a blocking member is detachably connected to the notch of the positioning groove on the positioning seat, the positioning groove penetrates in the horizontal direction and its horizontal extension direction is perpendicular to the guide hole and the inner hole of the limit seat, and the bottom wall of the positioning groove is not lower than the upper end of the guide hole.

[0007] This assembly tool is mainly used for the assembly of the outlet conductive rod and the vacuum switch tube outside the mold, and mainly involves the outlet conductive rod, the vacuum switch tube, the protective cover, the protective head and the metal shielding ring, wherein the vacuum switch tube and the protective head need to be fixed together first, and the vertical section of the outlet conductive rod and the protective cover can also be fixed together first (before fixing the vertical section of the outlet conductive rod and the protective cover, the metal shielding ring must be put on the vertical section of the outlet conductive rod). When using this assembly tool for assembly, first remove the blocking piece to make way for the notch of the positioning groove, then pass the vacuum switch tube through the guide hole with the moving end facing downward and make the protective head fixed on the moving end of the vacuum switch tube rest against the sliding seat; put the protective cover into the inner hole of the limit seat, and at the same time, the horizontal section of the outlet conductive rod should be aligned with the positioning groove and put in so that the end of the horizontal section of the outlet conductive rod is located above the guide hole. After the placement is completed, the blocking piece is installed to block the notch of the positioning groove so that the outlet conductive rod is positioned, and then the sliding seat is controlled to slide upward so that the static end of the vacuum switch tube is in contact with the horizontal section end of the outlet conductive rod, and then the horizontal section of the outlet conductive rod is fixed to the static end of the vacuum switch tube using fasteners.

[0008] By arranging the guide hole and the inner hole of the limit seat in parallel and the positioning groove being perpendicular to the guide hole and the inner hole of the limit seat in the horizontal extension direction, the distance between the guide hole and the inner hole of the limit seat can be directly designed according to the required distance between the vacuum switch tube and the vertical section of the outlet conductive rod, so that the vacuum switch tube and the outlet conductive rod only need to be installed in the corresponding position to automatically complete the alignment work, thereby improving the assembly efficiency; at the same time, the parallelism between the vacuum switch tube and the vertical section of the outlet conductive rod and the verticality between the vacuum switch tube and the horizontal section of the outlet conductive rod are guaranteed, thereby improving the assembly accuracy and ensuring the quality of the product after molding.

[0009] In the above-mentioned out-of-mold assembly tooling for a solid insulating tube, the positioning groove includes groove portion one and groove portion two, groove portion two is close to the guide hole, the groove bottom wall of groove portion one is a concave arc surface and the groove bottom wall of groove portion two is a plane, and the groove bottom wall of groove portion one is slightly higher than the groove bottom wall of groove portion two.

[0010] Through the above arrangement, the shape of the positioning groove matches the shape of the outlet conductive rod near the end of the horizontal section, thereby improving the positioning effect of the outlet conductive rod and further improving the assembly accuracy.

[0011] In the above-mentioned out-of-mold assembly tooling for a solid insulating cylinder, the positioning seat includes a seat plate and a guide ring and a protrusion that are fixedly connected to the seat plate, the guide hole is the center hole of the guide ring and the positioning groove is provided on the protrusion, and a boss is extended on one side of the protrusion to form abutment with the side of the guide ring, the upper side surface of the boss is flush with the bottom wall of the groove portion 2, and the side surface of the boss is flush with the upper edge of the guide ring.

[0012] Through the setting of the guide ring, the staff can directly put the bowl-shaped metal shielding cover on the guide ring to form a match with the horizontal section of the outgoing line conductive rod, that is, after the staff completes the connection between the outgoing line conductive rod and the vacuum switch tube using the assembly tool, they only need to put the bowl-shaped metal shielding cover on the guide ring again to further complete the assembly of the outgoing line conductive rod and the bowl-shaped metal shielding cover, which is equivalent to completing multiple required assemblies in one clamping, thereby further improving the assembly efficiency. At the same time, the boss extending from one side of the convex block to form abutment with the side of the guide ring can just match the notch on the bowl-shaped metal shielding cover, thereby ensuring that the bowl-shaped metal shielding cover will not be offset, ensuring the assembly efficiency.

[0013] In the above-mentioned out-of-mold assembly tooling for solid insulation cylinder, the blocking member is a long strip block, one end of the blocking member is hinged on the protrusion, the protrusion is also provided with a clamping column, and the other end of the blocking member is provided with a clamping slot for the clamping column to be inserted. The hinge point between the blocking member and the protrusion and the clamping column are respectively located on both sides of the positioning groove. When the blocking member rotates around the hinge point, the clamping column and the clamping slot can be matched or separated.

[0014] In the above-mentioned out-of-mold assembly tooling for solid insulating tubes, a mating cavity is provided on the upper side of the sliding seat, the mating cavity is an inverted cone-shaped cavity and the center line of the mating cavity is colinear with the center line of the guide hole, and an anti-rotation pin with a non-circular cross-section is provided on the sliding seat in the vertical direction, and the anti-rotation pin is located at the center of the mating cavity.

[0015] The moving end of the vacuum switch tube is fixed with a protective head, and the shape of the matching cavity and the protective head is matched to form the positioning of the vacuum switch tube. The moving end of the vacuum switch tube and the protective head are fixed by screws, so an anti-rotation pin is set in the matching cavity of the sliding seat, and the upper end of the anti-rotation pin is inserted into the concave hole of the screw head that fixes the moving end of the vacuum switch tube and the protective head to form an anti-rotation effect, so that when the static end of the vacuum switch tube is fixed to the power input end of the outgoing conductive rod, the vacuum switch tube can be ensured not to rotate, further improving the assembly accuracy.

[0016] In the above-mentioned out-of-mold assembly tool for solid insulating cylinder, a driving member 1 is provided on the frame, and the driving member 1 has a movable rod that can be telescopic in the vertical direction, and the end of the movable rod of the driving member 1 is fixedly connected to the lower center position of the sliding seat.

[0017] The sliding seat is driven by a driving member 1, thereby realizing intelligent control and improving assembly efficiency.

[0018] In the above-mentioned out-of-mold assembly tooling for solid insulation cylinders, the frame includes a base and two guide columns fixed to the base in parallel along the vertical direction. The two guide columns pass through the sliding seat and the positioning seat is fixed to the two guide columns. Limit springs for limiting the upward sliding height of the sliding seat are respectively provided at the same position on the two guide columns.

[0019] Limiting springs are respectively arranged at the same position of the two guide pillars, which can limit the upward sliding height of the sliding seat, thereby avoiding the vacuum switch tube or the outlet conductive rod from being damaged while ensuring the assembly requirements.

[0020] In the above-mentioned out-of-mold assembly tooling for solid insulating cylinders, two grooves connected to the inner hole of the limit seat are symmetrically arranged on the upper side of the limit seat, the connection direction between the two grooves and the coplanarity of the center line of the guide hole and the center line of the inner hole of the limit seat are perpendicular, and a clearance hole with an upper end connected to the inner hole of the limit seat is provided on the lower side of the frame.

[0021] Two pins are symmetrically arranged outside the protective cover. Their function is to push the protective cover together with the formed product out of the mold by applying force to the two pins after the solid insulating tube is formed. Therefore, the two pins also have special angle requirements. By symmetrically arranging two grooves on the upper side of the limit seat, the connection direction between the two grooves and the center line of the guide hole are perpendicular to the plane where the center line of the inner hole of the limit seat is located. At the same time, a clearance hole connected to the inner hole of the limit seat is arranged on the lower side of the frame. In this way, the staff only needs to align the two grooves with the two pins and put the protective cover into the inner hole of the limit seat, and then use fasteners to pass through the clearance hole on the lower side of the machine base and fix the protective cover to the end of the vertical section of the outlet conductive rod to ensure the required angle requirement, further improving the assembly accuracy. Conventionally, the protective cover and the outlet conductive rod are also connected by the staff directly holding the two components, but the present assembly tool can complete the alignment operation of the two at the same time, thereby further improving the assembly efficiency.

[0022] In the above-mentioned out-of-mold assembly tooling for solid insulating cylinders, a mounting plate and a stationary block are vertically fixed on the frame, a driving member 2 is fixed on one side of the mounting plate, the driving member 2 has a movable rod that can be extended and retracted in the direction vertical to the mounting plate, the movable rod of the driving member 2 passes through the mounting plate and is fixedly connected to the movable block, the movable block and the stationary block are arranged opposite to each other, a semicircular concave cavity 1 is provided on the side of the stationary block facing the movable block, and a semicircular concave cavity 2 is correspondingly provided on the movable block.

[0023] The mounting block and the stationary block are mainly used for the assembly between the vacuum switch tube and the protective head. In the initial state, the stationary block and the movable block are separated, and the vacuum switch tube is placed between the separated movable block and the stationary block with the moving end facing upward. Then, the movable block is controlled to move toward the stationary block through the driving part 2, and the movable block and the stationary block are brought together to clamp the vacuum switch tube. Then, just place the protective head at the moving end of the vacuum switch tube and fix it with screws.

[0024] In the above-mentioned out-of-mold assembly tooling for a solid insulating cylinder, a positioning column and an assembly block are fixedly connected to the frame, the positioning column is located on one side of the assembly block, and a communicating receiving groove and a clamping groove are provided on the upper side of the assembly block. The receiving groove passes through a side of the assembly block facing the positioning column, and the clamping groove is a square groove and passes through a side of the assembly block facing away from the positioning column.

[0025] The metal shielding ring has position requirements in the mold, so a card block will be connected to the end of the columnar connection part of the metal shielding ring (after forming the solid insulating cylinder, the end of the columnar connection part on the metal shielding ring is used to connect with other electrical components through fasteners), and the card block is used to cooperate with the corresponding position in the mold to achieve the positioning of the metal shielding ring, which means that there are also strict angle requirements between the card block and the metal shielding ring. The positioning column and the assembly block are mainly used for the assembly between the metal shielding ring and the card block. During assembly, the metal shielding ring is sleeved outside the positioning column and the columnar connection part integrally formed outside the metal shielding ring is located in the receiving groove. Then a card block is placed in the card groove and then a pin is used to pass through the card block and fixed to the end of the columnar connection part. When the metal shielding ring is loaded into the mold together with the main circuit, the card block is used to cooperate with the corresponding position in the mold to achieve positioning. Therefore, the use of the positioning column and the assembly block can strictly ensure the angle between the card block and the metal shielding ring, improve the assembly accuracy to ensure the quality of the product after molding.

[0026] Compared with the prior art, the out-of-mold assembly tool for solid insulation cylinder has the following advantages:

[0027] 1. The alignment process of connecting components is omitted, which improves assembly efficiency;

[0028] 2. Ensure the required verticality and parallelism after assembly, improve assembly accuracy, and thus ensure the quality of the product after molding;

[0029] 3. It integrates the assembly of metal shielding ring and clamping block, the assembly of bowl-shaped metal shielding cover and outgoing conductive rod, the assembly of outgoing conductive rod and protective cover, the assembly of vacuum switch tube and protective head, and the assembly of outgoing conductive rod and vacuum switch tube. It has richer functions and higher practical value. It can complete multiple required clampings in one clamping, further improving the assembly efficiency and assembly accuracy.

[0043] like Figure 1 and Figure 8 The outside mold assembly tooling for solid insulation cylinder shown in the figure includes a frame 1 and a positioning seat 2, a sliding seat 4 and a limiting seat 3 all arranged on the machine base 1a. The positioning seat 2 is fixed to the frame 1 and the sliding seat 4 is located below the positioning seat 2 and can slide upward. The positioning seat 2 is provided with a guide hole 2b1 penetrating at both ends in the vertical direction. The limiting seat 3 is fixed on the frame 1 and the limiting seat 3 is lower than the positioning seat 2. The limiting seat 3 has an inner hole 3a, and the inner hole 3a of the limiting seat 3 is parallel to the guide hole 2b1. A positioning groove 2c1 is provided on the upper side of the positioning seat 2, which is located between the guide hole 2b1 and the inner hole 3a of the limiting seat 3. A blocking member 5 is detachably connected to the notch of the positioning groove 2c1 on the positioning seat 2.

[0044] Specifically, if Figure 1 As shown, the frame 1 includes a base 1a and two guide columns 1b fixed to the base 1a in parallel in the vertical direction. The positioning base 2 is fixed at the ends of the two guide columns 1b and the two guide columns 1b pass through the sliding base 4. A driving member 16 is fixed on the base 1a. The driving member 16 has a movable rod that can be telescoped in the vertical direction. The end of the movable rod of the driving member 16 is fixedly connected to the lower center position of the sliding base 4. In this embodiment, the driving member 16 is a cylinder, and the movable rod is the piston rod of the cylinder. A limit spring 7 for limiting the upward sliding height of the sliding base 4 is respectively provided at the same position on the two guide columns 1b.

[0045] like Figure 8 As shown, the positioning seat 2 includes a seat plate 2a and a guide ring 2b and a projection 2c both fixedly connected to the seat plate 2a, the guide hole 2b1 is the central hole of the guide ring 2b and the positioning groove 2c1 is provided on the projection 2c. The positioning groove 2c1 includes a groove part 1 2c11 and a groove part 2c12, the groove part 2c12 is close to the guide hole 2b1 and the groove part 2c12 penetrates the side of the projection 2c close to the guide ring 2b, and the groove part 1 2c11 penetrates the side of the projection 2c away from the guide ring 2b. The groove bottom wall of the groove part 1 2c11 is a concave arc surface and the groove bottom wall of the groove part 2c12 is a plane, and the bottom wall of the groove part 1 2c11 is slightly higher than the groove bottom wall of the groove part 2c12. Furthermore, a boss 2c2 is extended from one side of the protrusion 2c to form abutment with the side of the guide ring 2b, and the upper side surface of the boss 2c2 is flush with the bottom wall of the groove portion 2c12, and the upper side surface of the boss 2c2 is flush with the upper end edge of the guide ring 2b.

[0046] Among them, Figure 8 As shown, the blocking member 5 is a long strip block, one end of the blocking member 5 is hinged on the protrusion 2c, and the protrusion 2c is also provided with a clamping column 8. The other end of the blocking member 5 is provided with a clamping slot 5a for the clamping column 8 to be clamped into. The hinge point between the blocking member 5 and the protrusion 2c and the clamping column 8 are respectively located on both sides of the positioning groove 2c1. When the blocking member 5 rotates around the hinge point, the clamping column 8 can cooperate with or separate from the clamping slot 5a.

[0047] like Figure 1 , Figure 3 and Figure 5 As shown, a matching cavity 4a is provided on the sliding seat 4. The matching cavity 4a is an inverted cone-shaped cavity, and the center line of the matching cavity 4a is colinear with the center line of the guide hole 2b1. An anti-rotation pin 4b with a non-circular cross section is provided on the sliding seat 4 in the vertical direction. The anti-rotation pin 4b is located at the center of the matching cavity 4a. In this embodiment, the cross section of the anti-rotation pin 4b is a regular hexagon.

[0048] like Figure 1 , Figure 3 and Figure 5 As shown, two grooves 3b are symmetrically arranged on the upper side of the limit seat 3, both of which are connected to the inner hole 3a of the limit seat 3, and the communication direction between the two grooves 3b is perpendicular to the coplanarity where the center line of the guide hole 2b1 and the center line of the inner hole 3a of the limit seat 3 are located. A clearance hole 1a1 connected to the inner hole 3a of the limit seat 3 is arranged on the lower side of the machine base 1a.

[0049] This assembly tool is mainly used for assembling some parts of the solid insulating cylinder outside the mold, that is, first assembling these parts together using this assembly tool and then putting them into the mold as a whole to form a solid insulating cylinder, mainly involving the outlet conductive rod 15, the vacuum switch tube 17, the protective cover 16, the protective head 18, the bowl-shaped metal shielding cover 19 and the metal shielding ring 20. During assembly, the blocking member 5 is rotated to make the positioning groove 2c1 available, and then the components to be assembled are placed roughly according to the following steps: 1. The protective cover 16 is placed into the inner hole 3a of the limiting seat 3 and the two pins 16a on the outer side of the protective cover 16 are ensured to be embedded in the two grooves 3b of the limiting seat 3; 2. The vacuum switch tube 17 is passed through the guide hole 2b1 with the moving end facing downward and the protective head 18 fixed to the moving end of the vacuum switch tube 17 is located in the matching cavity 4a of the sliding seat 4; 3. The metal shielding ring 20 is placed on the vertical section of the outgoing conductive rod 15 and then the vertical section of the outgoing conductive rod 15 is inserted into the protective cover 16. At the same time, the horizontal section of the outgoing conductive rod 15 should be aligned with the positioning groove 2c1 and placed so that the end of the horizontal section of the outgoing conductive rod 15 is located above the guide hole 2b1; 4. The blocking member 5 is rotated to block the outgoing conductive rod 15 at the positioning groove 2c1 to position the outgoing conductive rod 15.

[0050] After each component is placed, the status is as follows Figure 2 and Figure 3As shown. The protective cover 16 is fixed upwards to the end of the vertical section of the outgoing conductive rod 15 through the clearance hole 1a1 at the bottom of the machine base 1a by fasteners; the sliding seat 4 is controlled by the driving member 16 to push the vacuum switch tube 17 upwards, so that the static end of the vacuum switch tube 17 passes through the guide hole 2b1 and forms a contact with the horizontal section end of the outgoing conductive rod 15, and then the horizontal section of the outgoing conductive rod 15 is fixed to the static end of the vacuum switch tube 17 by fasteners. Figure 4 As shown, after the connection between the outgoing conductive rod 15 and the vacuum switch tube 17 is completed, the staff only needs to put the bowl-shaped metal shielding cover 19 outside the guide ring 2b, and then use the fasteners to fix the bowl-shaped metal shielding cover 19 to the horizontal section of the outgoing conductive rod 15. The state after the outgoing conductive rod 15 and the bowl-shaped metal shielding cover 19 are assembled is as shown in FIG. Figure 5 Through the above operation, the bowl-shaped metal shielding cover 19, the vacuum switch tube 17, the protection head 18, the outlet conductive rod 15, the protection cover 16 and the metal shielding ring 20 are assembled together (the state after the components are assembled together is as shown in FIG. Fig. 9 As shown), and because the guide hole 2b1 is parallel to the inner hole 3a of the limit seat 3 and with the help of the positioning groove 2c1, the alignment process between the components is omitted and the assembly efficiency is improved. At the same time, the parallelism and verticality are guaranteed to improve the assembly accuracy, thereby ensuring the quality of the product after molding.

[0051] Furthermore, if Figure 1 and Figure 6 As shown, a mounting plate 9 and a stationary block 10 are vertically fixed on the base 1a of the frame 1, and a driving member 11 is fixed on one side of the mounting plate 9. The driving member 11 has a movable rod that can be extended and retracted in the direction perpendicular to the mounting plate 9. The movable rod of the driving member 11 passes through the mounting plate 9 and is fixedly connected with a movable block 12. The movable block 12 is arranged opposite to the stationary block 10. A semicircular concave cavity 1 is provided on one side of the stationary block 10 facing the movable block 12, and a semicircular concave cavity 2 is correspondingly provided on the movable block 12. In this embodiment, the driving member 11 is a cylinder, and the movable rod is a piston rod of the cylinder. In addition to being cylinders, the driving member 16 and the driving member 2 11 can also be hydraulic cylinders.

[0052] The mounting block and the stationary block 10 are mainly used for assembling the vacuum switch tube 17 and the protection head 18. Figure 6 As shown, in the initial state, the stationary block 10 and the movable block 12 are separated, and the vacuum switch tube 17 is placed between the separated movable block 12 and the stationary block 10 with the moving end facing upward. Next, the movable block 12 is controlled to move toward the stationary block 10 by the driving member 2 11, and the movable block 12 and the stationary block 10 are brought together to clamp the vacuum switch tube 17, and then the protective head 18 is placed at the moving end of the vacuum switch tube 17 and fixed with screws.

[0053] Furthermore, if Figure 1 , Fig. 7A and Figure 7B As shown, a positioning column 13 and an assembly block 14 are fixedly connected to the base 1a of the frame 1, and the positioning column 13 is located on one side of the assembly block 14. A communicating receiving groove 14a and a clamping groove 14b are provided on the upper side of the assembly block 14, and the bottom wall of the receiving groove 14a is an inner concave arc surface, and the receiving groove 14a penetrates a side of the assembly block 14 facing the positioning column 13, and the clamping groove 14b is a square groove and penetrates a side of the assembly block 14 facing away from the positioning column 13.

[0054] The positioning column 13 and the assembly block 14 are mainly used for assembling the metal shielding ring 20 and the clamping block 21. Fig. 7A As shown, during assembly, the metal shielding ring 20 is sleeved outside the positioning column 13 and the columnar connecting portion 20a integrally formed outside the metal shielding ring 20 is located in the receiving groove 14a, and then a clamping block 21 is placed in the clamping groove 14b and then a pin is passed through the clamping block 21 and fixed to the end of the columnar connecting portion 20a, so that the metal shielding ring 20 and the clamping block 21 are fixed together by the pin. When the metal shielding ring 20 is put into the mold together with the assembled whole, the clamping block 21 cooperates with the corresponding position in the mold to achieve positioning. Therefore, the use of the positioning column 13 and the assembly block 14 can strictly ensure the angle between the clamping block 21 and the metal shielding ring 20, improve the assembly accuracy to ensure the quality of the product after molding.
