Description

Technical Field

[0001] The invention belongs to the technical field of electric energy meter production and testing lines and testing equipment, and in particular relates to an electric energy meter crimping mechanism. Background Art

[0002] Before leaving the factory, the electric energy meter needs to pass a test. One form of the test is that the detection pins on the test mechanism (including power pins, voltage pins, current pins, etc., all can be referred to as detection pins) and the corresponding metal terminals on the electric energy meter (including voltage terminals, current terminals, signal terminals, etc., all can be referred to as terminals. Where there are terminals on the electric energy meter, terminal slots, terminal holes and other structures will be set to arrange the terminals) contact each other, and the corresponding detection pins and terminals must also be pressed (fixed) against each other. They must not shake or be not pressed during the test, otherwise the test results will be inaccurate.

[0003] Common types of electric energy meters include three-phase meters, direct meters, terminal meters, etc. They have similar structures, but also have some "small differences".

In the prior art, the detection mechanism can usually only detect one type of electric energy meter.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0029] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, an electric energy meter crimping mechanism includes a main substrate 1, an electric energy meter fixture, a detection seat, a cylinder mounting seat 2 fixed relatively to the detection seat, an electric cylinder 3 for driving the electric energy meter fixture to move up and down, and a first detection switching cylinder 4 provided on the cylinder mounting seat 2;

[0030] The cylinder body of the electric cylinder 3 is arranged on the back of the main substrate 1, and the main substrate 1 is provided with a long through slot 1a penetrating the main substrate 1, and the cylinder rod of the electric cylinder 3 is provided with a pulling connection seat 301 passing through the long through slot 1a and being movable up and down along the long through slot 1a, and the electric energy meter fixture is connected to the pulling connection seat 301;

[0031] The detection seat includes a detection gauge support 501, on which are provided a plurality of detection needles 502 and a first switching seat 401 driven by a first detection switching cylinder 4. The first switching seat 401 is slidably connected to the detection gauge support 501. The sliding direction of the first switching seat 401 is parallel to the extension and retraction direction of the cylinder rod of the electric cylinder 3. The first switching seat 401 is provided with a plurality of detection needles 502.

[0032] The detection needle 502 itself belongs to the prior art, and the head of the detection needle 502 is used to contact and press the corresponding terminal.

[0033] For example, it is necessary to detect two types of electricity meters, type A and type B. Type A electricity meter has three more voltage terminals than type B electricity meter. Correspondingly, in terms of the detection socket, three more corresponding detection pins 502 (here named first switching pins) need to be set. Then the three extra first switching pins are set on the first switching socket 401.

[0034] In this way, when detecting type A electricity meter, the first detection switching cylinder 4 drives the first switching seat 401 to rise, driving the above-mentioned three detection needles 502 (first switching needles) to rise into place, and the worker installs the type A electricity meter on the electricity meter fixture. Subsequently, the electric cylinder 3 drives the connection seat 301 to move downward, thereby driving the electricity meter fixture and the type A electricity meter installed on the electricity meter fixture to move downward together, until each detection needle 502 (including the first switching needle) contacts and presses each terminal of the type A electricity meter (in fact, each terminal on the type A electricity meter moves down to contact and press each detection needle 502), and then power is turned on for detection. After the detection is completed, the electric cylinder 3 drives the connection seat 301, the electricity meter fixture and the type A electricity meter installed on the electricity meter fixture to reset, and the worker can take away the type A electricity meter installed on the electricity meter fixture.

[0035] When detecting a type B electric energy meter, the first detection switching cylinder 4 drives the first switching seat 401 to descend, driving the above three detection pins 502 (first switching pins) to descend and reset, and the worker installs the type B electric energy meter on the electric energy meter fixture. Subsequently, the electric cylinder 3 drives the connection seat 301 to move downward, thereby driving the electric energy meter fixture and the type B electric energy meter installed on the electric energy meter fixture to move downward together, until each detection pin 502 (excluding the first switching pin) contacts and presses each terminal of the type B electric energy meter (in fact, each terminal on the type B electric energy meter moves down to contact and press each detection pin 502), and then power is turned on for detection. After the detection is completed, the electric cylinder 3 drives the connection seat 301, the electric energy meter fixture and the type B electric energy meter installed on the electric energy meter fixture to reset, and the worker can take away the type B electric energy meter installed on the electric energy meter fixture.

[0036] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, it also includes a second detection switching cylinder 6 arranged on the cylinder mounting seat 2, and a second switching seat 601 driven by the second detection switching cylinder 6 is provided on the detection table support 501. The second switching seat 601 is slidably connected to the detection table support 501. The sliding direction of the second switching seat 601 is parallel to the extension and retraction direction of the cylinder rod of the electric cylinder 3, and a plurality of detection needles 502 are provided on the second switching seat 601.

[0037] Continuing with the examples in the previous text, in addition to the need to detect type A and type B electricity meters, it is also necessary to detect type C electricity meters. Type C electricity meters have two more power terminals than type B electricity meters. Correspondingly, in terms of the detection socket, two more corresponding detection pins 502 (here named second switching pins) are required. Then the two extra second switching pins are set on the second switching socket 601.

[0038] In this way, when detecting the C-type electric energy meter, the second detection switching cylinder 6 drives the second switching seat 601 to rise, driving the above-mentioned two detection needles 502 (second switching needles) to rise into place (when detecting the C-type electric energy meter, the first detection needle 502 does not rise and does not participate in the work), and the worker installs the C-type electric energy meter on the electric energy meter fixture. Subsequently, the electric cylinder 3 drives the connection seat 301 to move downward, thereby driving the electric energy meter fixture and the C-type electric energy meter installed on the electric energy meter fixture to move downward together, until each detection needle 502 (including the second switching needle, but not including the first switching needle) contacts and presses each terminal of the C-type electric energy meter (in fact, each terminal on the C-type electric energy meter moves down to contact and press each detection needle 502), and then power is turned on for detection. After the detection is completed, the electric cylinder 3 drives the connection seat 301, the electric energy meter fixture and the C-type electric energy meter installed on the electric energy meter fixture to reset, and the worker can take away the C-type electric energy meter installed on the electric energy meter fixture.

[0039] like Figure 1 , Figure 3 As shown, the cylinder body of the first detection switching cylinder 4 is fixed to the cylinder mounting seat 2, the cylinder rod of the first detection switching cylinder 4 is provided with a first floating joint 402, and the first floating joint 402 is connected to the first switching seat 401; the cylinder body of the second detection switching cylinder 6 is fixed to the cylinder mounting seat 2, the cylinder rod of the second detection switching cylinder 6 is provided with a second floating joint 602, and the second floating joint 602 is connected to the second switching seat 601.

[0040] The floating joint belongs to the existing technology, which is beneficial to ensure the smoothness of the movement process of the first switching seat 401 and protect the first detection switching cylinder 4. It is also beneficial to ensure the smoothness of the movement process of the second switching seat 601 and protect the second detection switching cylinder 6.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the electric energy meter fixture includes a back plate 701, two side limit assemblies for contacting the side walls of the electric energy meter, and an upper stop block 702 arranged on the top of the back plate 701, the two side limit assemblies are located on opposite sides of the back plate 701, and the side limit assemblies include at least one side limit block 703.

[0042] The worker can directly clamp the energy meter into the energy meter fixture, with the back of the energy meter vertically attached to the back plate 701, the front dial of the energy meter facing the worker, the side walls (left wall and right wall) of the energy meter both contact the side limit assembly (side limit block 703), and the top of the energy meter contacts the upper stop block 702. If different types of energy meters have different widths, they can also be adapted by replacing the side limit blocks 703 of different sizes.

[0043] like Figure 1 , Figure 3 , Figure 5 As shown, the electric energy meter fixture also includes two lower guard outer flanges 704 arranged at the bottom of the back plate 701, and the side of the lower guard outer flange 704 away from the main substrate 1 is the outer side of the flange, and the distance between the outer side of the flange and the main substrate 1 is M. When the electric energy meter is fixed by the electric energy meter fixture, the distance between the terminal on the electric energy meter closest to the main board and the main substrate 1 is N, and M<N.

[0044] The lower outer flange 704 can assist in limiting the electric energy meter, improve the stability of the electric energy meter after being fixed, and further ensure the structural stability during the detection process.

[0045] like Figure 1 , Figure 2 As shown, the side limit assembly includes two side limit blocks 703;

[0046] In a side limit assembly: one side limit block 703 is located directly above another side limit block 703;

[0047] In a side limit block 703 : the side limit block 703 includes a limit table block 703 . 1 and a limit base block 703 . 2 arranged on the main substrate 1 , and the limit table block 703 . 1 is provided with a screw threadedly connected to the limit base block 703 . 2 , and the axis of the screw is perpendicular to the back plate 701 .

[0048] The limit block 703.1 can be in a rectangular, columnar or other shape, and the side limit block 703 (limit block 703.1) can be rotated. In this way, by rotating the limit block 703.1, the distance between the two side limit components can be adjusted, thereby adapting to electric energy meters of different widths.

[0049] like Figure 3 , Figure 5 As shown, it also includes a base 8 fixed to the main base, and a plurality of springs 801 for supporting the detection seat are provided on the base 8. The lower end of the spring 801 is connected to the base 8, and the upper end of the spring 801 is connected to the detection seat. The detection seat is slidably connected to the main substrate 1, and the sliding direction of the detection seat is parallel to the extension and retraction direction of the cylinder rod of the electric cylinder 3.

[0050] In the actual detection process, since many steps are manually operated, it is inevitable that there will be a situation such as "to detect the B-type electric energy meter, but the detection needle 502 for detecting the A-type electric energy meter is provided", that is, to detect the B-type electric energy meter, but the first detection switching cylinder 4 does not drive the first switching seat 401 to descend, and the three first switching needles do not descend and reset. In this way, the three first switching needles become "redundant detection needles 502", and the "redundant detection needles 502" have no corresponding terminals (where there are terminals on the electric energy meter, terminal slots, terminal holes and other structures will be set to arrange the terminals, and where there are no terminals, no additional cost will be spent to arrange these terminal slots and terminal holes, so if the detection needle 502 can enter the terminal slot or terminal hole, it can contact the corresponding terminal. If the detection needle 502 does not have an accessible terminal slot or terminal hole, it can only directly contact the electric energy meter shell). Once the electric cylinder 3 drives the B-type electric energy meter to move downward, the bottom of the B-type electric energy meter shell will directly squeeze these "redundant detection needles 502" and cause these "redundant detection needles 502" to be damaged.

[0051] In view of this, a number of springs 801 for supporting the detection seat are provided in the present solution, and the detection seat can slide up and down. In this way, if the above-mentioned "terminals and detection pins 502 do not correspond, and detection pins 502 are redundant" occur, the bottom of the electric energy meter housing will push these "redundant detection pins 502" downward, and the detection pins 502 and the detection seat will drop together, and the springs 801 will be compressed, thereby protecting the detection pins 502.

[0052] like Figure 3 , Figure 4 , Figure 5 As shown, the detection table holder 501 is provided with a card slot 501a and an avoidance slot 501b above the card slot 501a, the upper end of the avoidance slot 501b passes through the upper end of the detection table holder 501, a hinge seat 503 is provided on the back of the main substrate 1, a transverse axis 504 rotatably connected to the hinge seat 503 is provided on the hinge seat 503, the transverse axis 504 is parallel to the main substrate 1, a torsion spring connected to the hinge seat 503 is sleeved on the transverse axis 504, the torsion spring is connected to the transverse axis 504, a C-shaped rod 505 is provided on the transverse axis 504, one end of the C-shaped rod 505 is provided with a pushed hemispherical head 505.1 that can be pushed by the electric energy meter fixture, and the other end of the C-shaped rod 505 is a lower limit end, and the main substrate 1 is provided with an upper avoidance opening 1b for the pushed hemispherical head 505.1 to pass through and a lower avoidance opening 1c for the lower limit end to pass through;

[0053] When the vertical projection of the thrust hemispherical head 505.1 overlaps with the vertical projection of the electric energy meter fixture: the lower limit end is in the lower avoidance opening 1c;

[0054] When the pushed hemispherical head 505.1 contacts the back of the electric energy meter fixture: the lower limit end is in the clamping groove 501a or in the avoidance groove 501b or above the avoidance groove 501b.

[0055] As mentioned above, if the "terminals and detection pins 502 do not correspond, and there are redundant detection pins 502", the bottom of the electric energy meter housing will push these "redundant detection pins 502" downward, and the detection pins 502 will move downward with the detection seat, and the spring 801 will be compressed, thereby protecting the detection pins 502.

[0056] Although the above method solves part of the problem, there is also a hidden necessary point, that is, "the stiffness of spring 801 is relatively small". This is because, if the stiffness of spring 801 is relatively large, when the bottom of the electric energy meter housing pushes the "extra detection needle 502" downward, causing the detection needle 502 and the detection seat to drop together, the compression of spring 801 will be more difficult. In this way, the detection needle 502 will still be damaged, so "the stiffness of spring 801 is relatively small".

[0057] However, the stiffness of the spring 801 is relatively small, and the supporting property is insufficient, which may easily lead to insufficient compression between the detection needle 502 and the corresponding terminal. How to solve this problem will be explained later.

[0058] In this solution, a spring 801 with a smaller stiffness is still selected. When a situation occurs, for example, "a type B electric energy meter needs to be detected, but a detection needle 502 for detecting a type A electric energy meter is provided", when the electric cylinder 3 drives the electric energy meter fixture and the type B electric energy meter to move downward, the bottom of the type B electric energy meter casing will press down and push these "redundant detection needles 502", and drive the entire detection seat to move downward, thereby protecting each detection needle 502.

[0059] How does this scheme ensure normal detection? The method is as follows: Normally, under the holding effect of the torsion spring, the pushed hemispherical head 505.1 is exposed outside the upper avoidance opening 1b (such as Figure 4 As shown in ), the lower limit end is in the lower avoidance opening 1c (as shown in Figure 4 In the normal detection process, the electric cylinder 3 drives the electric energy meter fixture and the electric energy meter to move downward. At a certain moment, the head of the detection needle 502 is close to the corresponding terminal, and the electric energy meter fixture (back plate 701) starts to push the pushed hemispherical head 505.1, and the C-shaped rod 505 rotates along the horizontal axis 504 ( Figure 4 In the perspective, the pushed hemispherical head 505.1 will move to the left), when the pushed hemispherical head 505.1 contacts the back of the back plate 701, the lower limit end is also exposed outside the lower avoidance opening 1c and enters the slot 501a, in this way, the slot 501a (detection meter support 501, detection needle 502) can be limited, and in the subsequent process of the electric energy meter fixture continuing to move downward, the pushed hemispherical head 505.1 is always in contact with the back of the back plate 701, and when the terminal and the head of the detection needle 502 are pressed against each other, the positioning of the detection needle 502 and the detection seat is achieved by relying on the lower limit end, thus avoiding the problem of low stiffness of the spring 801.

[0060] In addition, if, for example, a situation occurs in which "a type B electric energy meter is to be detected, but a detection needle 502 for detecting a type A electric energy meter is provided", before the back plate 701 contacts the pushed hemispherical head 505.1, a portion of the detection needle 502 (each first switching needle) has been contacted by the bottom of the type B electric energy meter housing, and the type B electric energy meter drives the detection needle 502 and the detection seat to move downward, and then the electric energy meter fixture (back plate 701) begins to contact the pushed hemispherical head 505.1. At this time, the groove 501a is no longer opposite to the lower limit end, but the avoidance groove 501b (the upper end of the avoidance groove 501b passes through to In this way, when the subsequent electric energy meter fixture (back plate 701) starts to push the pushed hemispherical head 505.1, the C-shaped rod 505 rotates along the horizontal axis 504. When the pushed hemispherical head 505.1 contacts the back of the back plate 701, the lower limit end is also exposed outside the lower avoidance port 1c and enters the avoidance groove 501b. In this way, the lower limit end will not limit the continuous downward movement of each detection needle 502 and the detection meter tow. Then, as the electric cylinder 3 drives the electric energy meter fixture and the B-type electric energy meter to move down to the right position, the detection needle 502 can continue to move down, which can protect the detection needle 502 from damage. In addition, if the electric energy meter moves down a large distance, the lower limit end may also reach the top of the avoidance groove 501b.

[0061] When the electric cylinder 3 drives the electric energy meter fixture to reset, once the pushed hemispherical head 505.1 leaves the back plate 701, the C-shaped rod 505 will automatically reset under the action of the torsion spring.

[0062] like Figure 1 , Figure 3 , Figure 4 As shown, the detection seat also includes a gasket assembly, which is located between the main substrate 1 and the detection table holder 501. The gasket assembly includes two symmetrically arranged side gaskets 506, and the side gaskets 506 are connected to the detection table holder 501 by screws.

[0063] By replacing the side gaskets 506 of different thicknesses, the present invention can be adapted to electric energy meters of different thicknesses.

[0064] The embodiments of the present invention are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
