Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for electrical equipment, and in particular to a three-station torque testing tooling fixture. Background Technology

[0002] The three-position switch in a GIS gas box requires precise control of the mechanical transmission torque during operation to ensure that the opening and closing actions are complete and without jamming. Therefore, after the three-position mechanism of the GIS gas box is assembled, a torque test is required to verify the mechanical fit of the transmission system and avoid the risk of arcing or poor contact due to improper operation. Existing torque testing equipment requires accurate docking with the three-position mechanism interface, a process that often requires multiple people working together, frequently moving and adjusting the position of the torque testing equipment. Coupled with limited operating space, this not only results in high labor intensity but also low work efficiency, failing to meet production needs.

[0003] Therefore, this utility model proposes a three-station torque testing fixture to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a three-station torque testing fixture, which facilitates the movement of the fixture and its interface with the three-station mechanism, thereby reducing labor intensity and improving work efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a three-station torque testing fixture, which is installed on a truss. Its innovation lies in the fact that the three-station torque testing fixture includes a suspension rod and a fixture fixing frame.

[0006] The suspension rod includes a suspension rod and a hanging ring. The suspension rod has a 7-shaped structure, and the hanging ring is installed on the top of the suspension rod. The hanging ring is installed on the truss via a telescopic electric drum and is moved up and down by the telescopic electric drum.

[0007] The fixture fixing frame includes a rear fixing plate and a front fixing plate. The rear fixing plate is installed at the bottom of the suspension rod and has a first mounting hole. The front fixing plate is parallel to the rear fixing plate and is connected to the rear fixing plate through a top plate. The front fixing plate has a second mounting hole with an internal gear ring inside. The three-position torque testing fixture passes through the first mounting hole and the second mounting hole in sequence. The outer wall of the three-position torque testing fixture has an external gear ring that matches the internal gear ring. The external gear ring is set in the second mounting hole and meshes with the internal gear ring. The outer wall of the three-position torque testing fixture has a limiting step surface that fits against the side wall of the front fixing plate near the rear fixing plate.

[0008] Furthermore, the lifting ring is connected to the suspension rod via a connector;

[0009] The connector includes a connecting seat and a movable fastening block. The lifting ring is installed on the top of the connecting seat. The bottom of the connecting seat has a slot for the movable fastening block to be inserted. There are two through holes on both sides of the slot on the connecting seat for the suspension rod to pass through. The suspension rod passes through the through hole on one side of the slot and enters the slot, and then exits through the through hole on the other side. The movable fastening block is inserted into the slot and is detachably connected to the connecting seat by a first screw. The movable fastening block and the connecting seat cooperate with each other to clamp the suspension rod.

[0010] Furthermore, the top plate has a first insertion protrusion on one side, and a first slot is opened on the rear fixing plate. The first insertion protrusion is inserted into the first slot. A triangular plate is vertically arranged above the top plate. One side of the triangular plate is connected to the rear fixing plate, and the other side is connected to the top plate.

[0011] Furthermore, the top plate has a second slot on the side away from the first insertion protrusion, and the top of the front fixing plate has a second insertion protrusion. The second insertion protrusion is inserted into the second slot, and the two sides of the second slot of the top plate are detachably connected to the front fixing plate by second screws.

[0012] Furthermore, the tooling fixing frame also includes two box corner positioning blocks, which are located on the side of the front fixing plate away from the rear fixing plate. The two box corner positioning blocks are located on both sides of the front fixing plate, and each box corner positioning block is connected to the rear positioning plate through an L-shaped connecting rod.

[0013] Furthermore, a pull handle is installed at the bottom of the rear fixing plate, and an operating handle is installed on one side of the rear fixing plate.

[0014] The advantages of this utility model are:

[0015] The fixture of this invention is suspended by a telescopic electric drum below the truss. When a three-position torque test is required, the fixture is simply installed on the fixture in advance. The fixture is supported by two fixed plates, front and rear, and the internal gear ring in the front fixed plate prevents the fixture from rotating. The limiting step surface on the outer wall of the fixture limits the relative position between the fixture and the front fixed plate, thereby preventing the external gear ring and the internal gear ring of the fixture from disengaging. When the fixture is docked with the three-position mechanism, the fixture with the fixture is simply pulled down to the specified height, and then the fixture is pushed to move and adjust the position of the fixture to complete the docking. This method has low labor intensity, does not interfere with ground equipment, and is easy to operate.

[0016] It facilitates tooling movement and interface with three-station mechanisms, reducing labor intensity and improving work efficiency.

[0017] The lifting ring of this utility model is connected to the suspension rod through a connector. The suspension rod is movably inserted into the through hole of the connecting seat. The relative position of the connecting seat on the suspension rod can be adjusted according to the size of the installed fixture, thereby adjusting the lifting point. This ensures that the fixture remains horizontal and stable after the fixture is installed. After adjustment, the connecting seat is fixed with a movable fastening block to prevent relative displacement between the suspension rod and the connector during the use of the fixture, which would affect stability.

[0018] This utility model features a first insertion protrusion on the top plate. When installing the top plate, the first insertion protrusion can be inserted into the first slot first to pre-position the top plate and the rear fixing plate before installing the triangular plate, making the operation simple.

[0019] The front fixing plate of this utility model is pre-positioned with the top plate by plugging it in, and then detachably connected to the front fixing plate by a second screw, which facilitates the replacement of the front fixing plate and avoids the problem of tooling shaking caused by wear of the internal gear ring due to long-term use of the front fixing plate.

[0020] This utility model sets corner positioning blocks on both sides of the tooling fixing frame. When the tooling on the fixture is connected to the three-position interface of the air box, the fixture is moved to make the air box body enter between the two corner positioning blocks, thereby positioning the relative position of the fixture and the air box body, and realizing the rapid connection between the tooling and the three-position interface of the air box.

[0021] This invention features two handles on the rear fixed plate, allowing testers to apply force to move and adjust the position of the fixture. Attached Figure Description

[0030] This embodiment provides a three-station torque testing fixture, such as... Figure 1-5 As shown, the three-station torque testing fixture includes a suspension rod and a fixture fixing frame.

[0031] The suspension rod includes a suspension rod 1 and a lifting ring 3. The suspension rod 1 has a 7-shaped structure. The lifting ring 3 is installed on the top of the suspension rod 1. The lifting ring 3 is installed at the torque test station of the truss through a telescopic electric drum and is moved up and down by the telescopic electric drum.

[0032] In this embodiment, the lifting ring 3 is connected to the suspension rod 1 through the connector 2; the connector 2 includes a connecting seat 21 and a movable fastening block 22. The lifting ring 3 is installed on the top of the connecting seat 21. The bottom of the connecting seat 21 has a slot 23 for the movable fastening block 22 to be inserted. There are two through holes 24 on both sides of the slot 23 on the connecting seat 21 for the suspension rod 1 to pass through. After the suspension rod 1 passes through the through hole on one side of the slot 23 and enters the slot 23, it exits through the through hole on the other side. The movable fastening block 22 is inserted into the slot 23. Each side of the movable fastening block 22 is detachably connected to the connecting seat 21 by a first screw. The movable fastening block 22 and the connecting seat 21 cooperate with each other to clamp the suspension rod 1. The inspector can adjust the relative position of the connecting seat 2 on the suspension rod 1 according to the size of the installed fixture, thereby adjusting the lifting point so that the fixture remains horizontal and stable after the fixture is installed. After adjustment, tighten the first screw and use the movable fastening block 22 to fix the connecting piece, so as to avoid relative displacement between the suspension rod 1 and the connecting piece 2 during the use of the fixture, which would affect the stability.

[0033] The fixture fixing frame includes a rear fixing plate 4 and a front fixing plate 5. The rear fixing plate 4 is installed at the bottom end 1 of the suspension rod and has a first mounting hole 42. The front fixing plate 5 is parallel to the rear fixing plate 4 and is connected to the rear fixing plate 4 through a top plate 6. The front fixing plate 5 has a second mounting hole and an internal gear ring 51 inside the second mounting hole. The three-position torque testing fixture 13 passes through the first mounting hole 42 and the second mounting hole in sequence. The outer wall of the three-position torque testing fixture 13 has an external gear ring 131 that matches the internal gear ring 51. The external gear ring 131 is set in the second mounting hole and meshes with the internal gear ring 51. The outer wall of the three-position torque testing fixture 13 has a limiting step surface 132. The limiting step surface 132 is in contact with the side wall of the front fixing plate 5 near the rear fixing plate 4.

[0034] In this embodiment, the top plate 6 has a first insertion protrusion 61 on one side, and the rear fixing plate 4 has a first slot 41. The first insertion protrusion 61 is inserted into the first slot 41. A triangular plate 8 is vertically arranged at the center of the top plate 6. One side of the triangular plate 8 is welded to the rear fixing plate 4, and the other side is welded to the top plate 6. The top plate 6 has a second slot 62 at the center of the side away from the first insertion protrusion 61. The top of the front fixing plate 5 has a second insertion protrusion 52, which is inserted into the second slot 62. The two sides of the second slot 62 of the top plate 6 are detachably connected to the front fixing plate 5 by two second screws, which facilitates the replacement of the front fixing plate 5 and avoids the problem of tooling shaking caused by wear of the internal gear ring 51 due to long-term use of the front fixing plate 5. The tooling fixture also includes two corner positioning blocks 10. These two corner positioning blocks 10 are located on the side of the front fixing plate 5 furthest from the rear fixing plate 4, and are positioned on opposite sides of the front fixing plate 5. Each corner positioning block 10 is connected to the rear fixing plate 4 via an L-shaped connecting rod 9. One end of the L-shaped connecting rod 9 is connected to the rear fixing plate 4, and the other end is connected to the corner positioning block 10. The corner positioning block 10 is installed on the side of the L-shaped connecting rod 9 closest to the front fixing plate 5. The corner positioning block 10 has an L-shaped structure that matches the corner of the gas box. The two corner positioning blocks 10 cooperate to form a positioning groove for the gas box body to enter. The opening of the positioning groove for the gas box body to enter has a flared opening to facilitate the entry of the gas box body into the positioning groove. When the tooling on the fixture aligns with the three-position interface of the gas box, the fixture is moved to allow the gas box body to enter the positioning groove between the two corner positioning blocks, thereby positioning the relative position of the fixture and the gas box body and achieving rapid alignment between the tooling and the three-position interface of the gas box.

[0035] In this embodiment, a pull handle 12 is installed at the bottom of the rear fixing plate 4, and an operating handle 11 is installed on one side of the rear fixing plate 4. The operating handle 11 is connected to the rear fixing plate 4 through a connecting plate, which makes it convenient for the tester to apply force to move and adjust the position of the fixture as needed.

[0036] The fixture is suspended by a telescopic electric drum below the truss. When a three-station torque test is required, the fixture is simply installed on the fixture in advance. The fixture is supported by two fixed plates, front and rear, and the internal gear ring 51 in the front fixed plate 5 prevents the fixture from rotating. The limiting step surface 132 on the outer wall of the fixture limits the relative position between the fixture and the front fixed plate 5, thus preventing the outer gear ring 131 of the fixture from disengaging from the inner gear ring 51. When the fixture is docked with the three-station mechanism, the fixture with the fixture is simply pulled down to the specified height, and then the fixture is pushed to move and adjust the position of the fixture to complete the docking. The labor intensity is low, and there is no interference with the ground equipment, making the operation convenient.
