Description

Technical Field

[0001] This utility model relates to the field of current transformer assembly technology, specifically to an assembly table for processing current transformers that can assist in calibration. Background Technology

[0002] With the rapid development of electronic equipment, the application of current transformers is becoming increasingly common. A current transformer is a common electronic structure that measures current by converting a large primary current into a small secondary current based on the principle of electromagnetic induction. A current transformer consists of a closed iron core and windings. Its primary winding has very few turns and is connected in series with the circuit whose current needs to be measured. During operation, the secondary circuit of the current transformer is always closed, resulting in very low impedance between the measuring instrument and the series coil of the protection circuit. The operating state of the current transformer is close to a short circuit. Current transformers are widely used in modern industry, such as for inductive power supply and for measuring electrical parameters. When using a current transformer, it needs to be assembled.

[0003] Existing assembly tables mostly use clamps to fix current transformers during assembly to prevent misalignment during the assembly process. This also assists personnel in calibration and facilitates the assembly work. However, if personnel do not stop clamping in time when using existing clamps to tighten the current transformers, the clamping force may be too great, causing deformation of the current transformer components and serious damage, which will affect subsequent normal use. Utility Model Content

[0004] The purpose of this invention is to provide an assembly table for processing current transformers that can assist in calibration, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an assembly table for processing current transformers that can assist in calibration, comprising a worktable, a cylinder fixed to the bottom of the worktable, the output end of the cylinder penetrating the worktable, an assembly table fixed to the top of the output end of the cylinder, and the surface of the assembly table being provided with a fixing component for stabilizing the current transformer and a protective component for preventing damage to the current transformer. The fixing component includes: a fixing clamp, a fixing plate, a slider, a screw, a groove, a movable clamp, a spring, and a round block. The protective component includes:

[0006] A fixed rod is fixed to the surface of the movable clamping block. A sliding groove is formed on the surface of the fixed rod. A sliding rod is slidably connected to the inner wall of the sliding groove. A second spring is fixed to the surface of the sliding rod. The end of the second spring away from the sliding rod is fixed to the inner wall of the sliding groove.

[0007] Preferably, the protective assembly further includes an arc-shaped groove formed on the surface of the slide rod. A fixed seat is fixed to the end of the fixed rod away from the movable clamping block. The slide rod passes through the fixed seat, and a cavity is formed inside the fixed seat. A circular plate is rotatably connected to the inner wall of the cavity, and the slide rod passes through the circular plate. A through hole is formed on the surface of the circular plate, and a short rod abuts against the inner side of the through hole. A long rod is fixed to the surface of the short rod, and the end of the long rod away from the short rod passes through the fixed seat and is slidably connected to the fixed seat. A connecting groove is formed on the surface of the long rod, and the inner wall of the connecting groove slides through the groove. A locking block is connected to the circular plate. A spring is fixed to the surface of the locking block. The end of the spring away from the locking block is fixed to the inner wall of the connecting groove. An abutting rod is provided on the inner side of the circular plate. An abutting groove is provided on the side of the circular block near the circular block. A locking groove is provided on the inner side of the abutting groove. The surface of the sliding rod abuts against the inner wall of the abutting groove. The sliding rod enters the sliding groove. The inner wall of the arc-shaped sliding groove abuts against the surface of the abutting rod. The circular plate rotates clockwise. Through the through hole, short rod, long rod, and locking block, the side of the locking block away from the inclined plane abuts against the inner wall of the abutting groove. The locking block, the abutting groove, and the circular block limit each other. At this time, the circular block and the screw cannot continue to rotate.

[0008] Preferably, the fixing clamp is fixed to the top of the assembly table, the fixing plate is fixed to the top of the assembly table, the surface of the fixing plate is provided with a screw, the screw passes through the fixing plate and is threadedly connected to the fixing plate, a round block is fixed to the right end of the screw, a slider passes through the end of the round block away from the screw, the slider is slidably connected to the top of the assembly table, a groove is opened at the right end of the slider, a movable clamp is slidably connected to the inner wall of the groove, a spring is fixed to the surface of the movable clamp, the end of the spring away from the movable clamp is fixed to the inner wall of the groove, the round block and the slider are rotatably connected, rotating the screw clockwise will drive the round block to rotate, so that the slider will drive the movable clamp to move closer to the fixing clamp, and reversing the direction will move it away, which facilitates clamping and releasing.

[0009] Preferably, the end of the locking block away from the spring is set as an inclined surface. When the contact groove contacts the inclined surface, the locking block can move without hindering the normal reversal of the round block.

[0010] Preferably, the through hole is arc-shaped, so that when the circular plate rotates, it can drive the short rod, long rod, and locking block to move radially in sync.

[0011] Preferably, the end of the abutment rod away from the circular plate extends into the arc-shaped groove. When the sliding rod moves, it abuts against the inner wall of the arc-shaped groove, thereby driving the circular plate to rotate.

[0012] Compared with the prior art, this utility model provides an assembly table for processing current transformers that can assist in calibration, and has the following beneficial effects:

[0013] 1. This calibrable current transformer assembly table, through its protective components, clamps the current transformer by using a sliding rod, spring 1, fixed seat, arc-shaped slide groove, contact rod, through hole, short rod, long rod, and locking block. This ensures that the side of the locking block away from the inclined plane contacts the inner wall of the contact groove, and the locking block, contact groove, and round block mutually limit each other. At this time, the round block and screw cannot continue to rotate, which can prevent excessive clamping force caused by the screw not stopping rotating in time, resulting in deformation or even damage to the current transformer.

[0014] 2. This calibrating assembly table for current transformer processing, through the fixed components, can drive the circular block to rotate by rotating the screw in the forward direction, so that the slider moves the movable clamping block closer to the fixed clamping block, and moves it away in the reverse direction, which facilitates clamping and loosening, and assists in the calibration of current transformer accessories, without causing deviation during assembly.

[0023] like Figures 1-7As shown, this utility model provides a technical solution: an assembly table for processing current transformers that can assist in calibration, including a workbench 1, a cylinder 2 fixed to the bottom of the workbench 1, the output end of the cylinder 2 passing through the workbench 1, and an assembly table 3 fixed to the top of the output end of the cylinder 2. The surface of the assembly table 3 is provided with a fixing component 4 for stabilizing the current transformer and a protective component 5 for preventing damage to the current transformer. The fixing component 4 includes: a fixing clamp 40, a fixing plate 41, a slider 42, a screw 43, a groove 44, a movable clamp 45, a spring 46, and a round block 47. The protective component 5 includes: a fixing rod 50, which is fixed to the surface of the movable clamp 45. The fixed rod 50 has a groove 51 on its surface. A slide rod 52 is slidably connected to the inner wall of the groove 51. A second spring 53 is fixed to the surface of the slide rod 52. The end of the second spring 53 away from the slide rod 52 is fixed to the inner wall of the groove 51. The protective component 5 also includes an arc-shaped groove 54, which is formed on the surface of the slide rod 52. A fixed seat 55 is fixed to the end of the fixed rod 50 away from the movable clamp 45. The slide rod 52 passes through the fixed seat 55. A cavity 56 is formed inside the fixed seat 55. A circular plate 57 is rotatably connected to the inner wall of the cavity 56. The circular plate 57 is penetrated by the slide rod 52. A through hole 58 is formed on the surface of the circular plate 57. A short rod 59 abuts against the inside of the through hole 58. A long rod 500 is fixed to the surface of rod 59. The end of the long rod 500 away from the short rod 59 passes through the fixed seat 55, and the long rod 500 is slidably connected to the fixed seat 55. A connecting groove 501 is formed on the surface of the long rod 500. A locking block 502 is slidably connected to the inner wall of the connecting groove 501. A spring 503 is fixed to the surface of the locking block 502. The end of the spring 503 away from the locking block 502 is fixed to the inner wall of the connecting groove 501. An abutment rod 504 is formed on the inner side of the circular plate 57. An abutment groove 506 is formed on the side of the circular block 47 near the circular block 47. A locking groove 505 is formed on the inner side of the abutment groove 506. The end of the locking block 502 away from the spring 503 is set as an inclined surface. The hole 58 is set to be arc-shaped. The end of the abutment rod 504 away from the circular plate 57 extends into the arc-shaped slide groove 54. The surface of the slide rod 52 abuts against the inner wall of the abutment groove 506. The slide rod 52 enters the slide groove 51, the spring 2 53 is compressed, and at the same time the inner wall of the arc-shaped slide groove 54 abuts against the surface of the abutment rod 504. The circular plate 57 rotates clockwise, and the inner wall of the through hole 58 abuts against the surface of the short rod 59, which drives the long rod 500 and the locking block 502 to move radially in sync. When the locking block 502 enters the abutment groove 506, the side of the locking block 502 away from the inclined surface abuts against the inner wall of the abutment groove 506. The locking block 502, the abutment groove 506, and the circular block 47 limit each other. At this time, the circular block 47 and the screw 43 cannot continue to rotate.

[0024] The fixed clamping block 40 is fixed to the top of the assembly table 3, and the fixed plate 41 is fixed to the top of the assembly table 3. The surface of the fixed plate 41 is provided with a screw 43, which passes through the fixed plate 41 and is threadedly connected to the fixed plate 41. A round block 47 is fixed to the right end of the screw 43. A slider 42 passes through the end of the round block 47 away from the screw 43. The slider 42 is slidably connected to the top of the assembly table 3. A groove 44 is opened at the right end of the slider 42. A movable clamping block 45 is slidably connected to the inner wall of the groove 44. A spring 46 is fixed to the surface of the movable clamping block 45. The end of the spring 46 away from the movable clamping block 45 is fixed to the inner wall of the groove 44. The round block 47 is rotatably connected to the slider 42. Rotating the screw 43 clockwise will drive the round block 47 to rotate, causing the slider 42 to move the movable clamping block 45 closer to the fixed clamping block 40, thereby fixing and clamping the current transformer accessories. Reversing the direction will release the clamping block.

[0025] When assembling the current transformer, place it on the surface of the assembly table 3. Rotating the screw 43 clockwise will cause the circular block 47 to rotate, causing the slider 42 to move the movable clamping block 45 closer to the fixed clamping block 40. This clamps the current transformer components, allowing for auxiliary calibration and preventing misalignment during assembly. Continuing to rotate the screw 43 moves the movable clamping block 45 into the groove 44, compressing the spring 46. The movable clamping block 45 then moves the fixed clamping block 40... The fixed rod 50, fixed seat 55, and sliding rod 52 move closer to the contact groove 506. When the surface of the sliding rod 52 abuts against the inner wall of the contact groove 506, the sliding rod 52 enters the sliding groove 51, and the spring 53 is compressed. At the same time, as the sliding rod 52 moves, the inner wall of the arc-shaped sliding groove 54 abuts against the surface of the contact rod 504, thereby driving the circular plate 57 to rotate clockwise, so that the inner wall of the through hole 58 abuts against the surface of the short rod 59, thereby driving the long rod 500 and the locking block 502 to move radially in sync. When the locking block 502 enters... When the locking block 502 is inserted into the contact groove 506, the side of the locking block 502 away from the inclined surface abuts against the inner wall of the contact groove 506. At this time, the locking block 502, the contact groove 506, and the round block 47 mutually limit each other. At this time, the round block 47 and the screw 43 cannot continue to rotate, thus avoiding excessive clamping force caused by the screw 43 not stopping rotating in time, which could cause deformation or even damage to the current transformer. At this time, the personnel can carry out the assembly work normally. When it is necessary to remove the device after assembly, reverse the screw 43 and the round block 47. At this time, the contact... The groove 506 abuts against the inclined surface of the locking block 502, allowing the locking block 502 to enter the connecting groove 501 without affecting the normal reverse rotation of the round block 47 and the screw 43. This drives the slider 42 and the movable clamping block 45 away from the current transformer, making it easy for personnel to remove them. At the same time, the spring 1 46 and the spring 2 53 drive the movable clamping block 45, the slide rod 52, the long rod 500, and the locking block 502 to reset. Simultaneously, the assembly table 3 can be raised by opening the cylinder 2, making it easy to adjust its height and facilitate assembly work.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
