Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary wiring tooling for electric energy meter detection, in particular to a manual crimping tooling for round meters. Background Art

[0002] After a typical electric energy meter is assembled, it needs to be calibrated to determine whether it is accurate. Calibration requires the use of a calibration auxiliary wiring device for electrically connecting the electric energy meter and the detection device. Generally, the calibration auxiliary wiring device and the detection device are electrically connected in advance, and then during calibration, the electric energy meter only needs to be plugged into the calibration auxiliary wiring device, which improves the efficiency of connecting the electric energy meter and the detection device.

[0003] A circular electric energy meter in the prior art includes a circular meter head and two rows of pins extending from the lower end of the meter head.

[0004] The patent announcement number "CN221631660U" records that "an auxiliary device for calibrating an electric energy meter" includes a base, and the front side of the base is provided with at least one group of clamping and mounting mechanisms. The clamping and mounting mechanisms include a fixed block fixed on the base and a sliding block that slides. The sliding block is driven by a driving mechanism to slide close to or away from the fixed block. A socket is formed when the sliding block and the fixed block are brought close to each other. A copper sheet is provided on at least one of the two opposite sides of the sliding block and the fixed block. The copper sheet is located in the socket. The copper sheets in the four sockets on the device are respectively connected to the calibration device through wires, and then the four terminals of the meter are respectively aligned with the four sockets and inserted and attached to the copper sheet, thereby electrically connecting to the calibration device. After the calibration is completed, the meter is directly unplugged. Through the device of the utility model, the meter and the calibration device can be quickly connected and calibrated, avoiding the need to connect wires one by one, thereby improving work efficiency.

[0005] The manual also records in detail that the two sliding blocks are driven to move toward the corresponding fixed blocks by the sliding bar arranged in the length direction and the extrusion block on the sliding bar to clamp the pins of the electric energy meter, and a cylinder is installed in the length direction to drive the sliding bar to move. In this way, the length dimension of the auxiliary device is greatly increased. Therefore, if the length dimension provided by the installation position of the actual production line is not sufficient to install the above-mentioned auxiliary device, it is necessary to design an auxiliary wiring tool with a short length dimension.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] A manual crimping tool for a circular meter includes a base plate 1, which is provided with mounting holes for mounting the present invention on a production line frame. The upper end of the base plate 1 is provided with two groups of symmetrical clamping components, and the two groups of clamping components respectively correspond to the two rows of pins 18 at the lower end of the circular meter 17.

[0022] The clamping assembly includes a first clamping block 2 located on the outside and a second clamping block 3 located on the inside. The first clamping block 2 is fixed on the base plate 1. A notch 4 is provided on the side of the first clamping block 2 facing the second clamping block 3. The number of notches 4 is equivalent to the number of pins 18 in the same column at the lower end of the circular meter 17, and they correspond one to one. A through hole 6 corresponding to the notch 4 is penetrated on the base plate 1. A copper sheet 5 is fixed in the notch 4. The copper sheet 5 has a conductive function. The lower end of the copper sheet 5 extends through the through hole 6 to the bottom of the base plate 1.

[0023] The second clamping block 3 is slidably installed on the base plate 1, and the second clamping block 3 moves parallel to the connecting direction of the first clamping block 2 and the second clamping block 3. The two second clamping blocks 3 move toward or away from the corresponding first clamping block 2 synchronously.

[0024] The two second clamping blocks 3 are driven by the same double-threaded screw 11 to move synchronously. The double-threaded screw 11 has two sections of external threads of the same specifications. A threaded hole is provided along the direction of movement on the two second clamping blocks 3. The threaded hole is provided with an internal thread matching the external thread. The double-threaded screw 11 passes through the two second clamping blocks 3 through the threaded hole, and the two sections of external threads on the double-threaded screw 11 are respectively adapted to the internal threads in the two threaded holes. The double-threaded screw 11 is rotatably installed on the base plate 1. One end of the double-threaded screw 11 is connected to a rotating handle 12. The double-threaded screw 11 is manually rotated by rotating the handle 12. A notch for the double-threaded screw 11 to pass through is provided on the first clamping block 2, and the double-threaded screw 11 does not contact the first clamping block 2.

[0025] Before testing, the utility model is pre-installed on the rack of the testing production line, and several copper sheets 5 are extended to one end below the base plate 1 and electrically connected to the testing equipment via wires. After the test begins, the two rows of pins 18 of the circular gauge 17 are inserted one by one into the corresponding notches 4. The rotating handle 12 is then manually driven to rotate, thereby driving the double-threaded screw 11 to rotate. Driven by the double-threaded screw 11, the two second clamping blocks 3 move toward the corresponding first clamping blocks 2, thereby pressing the pins 18 of the circular gauge 17 against the first clamping blocks 2 through the second clamping blocks 3. The second clamping blocks 3 squeeze the pins 18, making them tightly attached to the copper sheet 5, thereby electrically connecting the circular gauge 17 to the testing equipment. After the test is completed, the rotating handle 12 is rotated in the opposite direction, and the second clamping blocks 3 move away from the corresponding first clamping blocks 2, thereby loosening the pins 18 of the circular gauge 17, making it easier to remove the circular gauge 17 from the tooling after the test is completed.

[0026] The two second clamping blocks move under the drive of the double-threaded screw, and the double-threaded screw is driven to rotate by turning the handle, thereby setting the driving structure of the two second clamping blocks in the width direction of the tooling. Compared with the auxiliary device mentioned in the background technology, the length of the utility model is greatly reduced, and it can meet the installation requirements of installation positions that are insufficient in length.

[0027] According to a preferred technical solution, an insulating pad 7 corresponding to the notch 4 is fixed on the side of the second clamping block 3 facing the first clamping block 2. The insulating pad 7 is pressed against the pin 18 of the round table 17, further ensuring that the pin 18 is pressed against the copper sheet 5, ensuring good contact between the pin 18 and the copper sheet 5, and the insulating pad 7 can prevent the second clamping block 3 from making hard contact with the pin 18, thereby avoiding scratching the pin 18.

[0028] According to a preferred technical solution, a socket 15 extending downward is provided at the upper end of the first clamp 2 corresponding to the notch 4, and the socket 15 is located in the direction of the notch 4 away from the second clamp 3. The upper end of the copper sheet 5 is bent downward to form a plug-in portion 16 matching the socket 15, and the plug-in portion 16 is inserted into the socket 15. A hook is formed at the upper end of the copper sheet 5 by the bent plug-in portion 16, thereby hanging the copper sheet 5 on the first clamp 2, facilitating the installation and disassembly of the copper sheet 5.

[0029] According to the preferred technical solution, a slide groove 8 is provided at the upper end of the base plate 1 along the moving direction of the second clamping block 3, and a first slider 9 is fixedly connected to the lower end of the second clamping block 3 and matched to slide in the slide groove 8. The second clamping block 3 is slidably installed on the base plate 1 through the slide groove 8.

[0030] The preferred technical solution is that the distance of the first clamping block 2 can be adjusted, and a strip groove 13 is provided on the first clamping block 2. The depth of the strip groove 13 runs through the first clamping block 2, and the length of the strip groove 13 is parallel to the connecting direction of the first clamping block 2 and the second clamping block 3. A vertical bolt 14 is provided in the strip groove 13, and the lower end of the bolt 14 is screwed to the base plate 1. The lower end of the first clamping block 2 is fixedly connected with a second slider 10 that slides in the slide groove 8. By loosening the bolt 14, the first clamping block 2 can be moved in a moving direction parallel to the second clamping block 3 through the strip groove 13, thereby adjusting the position of the first clamping block 2 so that the first clamping block 2 can be located in a suitable position corresponding to the pin 18 of the circular meter 17. After adjustment, tighten the bolt 14 to lock the first clamping block 2 on the base plate 1.
