Description

Technical Field

[0001] The utility model relates to the technical field of relay contact detection equipment, in particular to a relay contact amplification and measurement device. Background Art

[0002] Relay contacts are an important part of the relay, which are responsible for current conduction and conversion. After the relay contacts are processed, sampling inspection is required to measure the size of the relay contacts. Since the size of the relay contacts is small, in order to improve the measurement accuracy, when measuring the relay contacts, it is generally necessary to use an amplifying measuring instrument to amplify the relay contacts for measurement;

[0003] For example, Figure 7 A relay contact magnification measuring device in the prior art is shown in the figure, comprising a machine base, a support is installed on the top of the machine base through an adjustment mechanism, a support plate is detachably fixed on the top of the support through bolts, a placement slot is provided on the support plate, a frame is fixedly installed on the machine base and on one side of the support, a high-power camera is fixedly installed on the frame and directly above the placement slot, a display screen connected to the high-power camera for communication is provided on the frame, and a fill light is provided on the frame and on the outside of the high-power camera. When measuring the relay contact, since the relay contact is irregular in shape, it is necessary to first position the relay contact using a positioning mechanism, and then place the positioning mechanism in the placement slot so that the relay contact is placed in the placement slot, fill light is used to fill light on the relay contact, and the high-power camera is used to capture an image of the relay contact onto the display screen, and then the position of the support is adjusted by the adjustment mechanism to achieve position adjustment of the relay contact, so that the relay contact is imaged to a fixed area of ​​the display screen, and the size is measured by observing the display screen; although this method can magnify and measure the relay contact, in actual use, there are still the following defects:

[0004] Since the relay contact is positioned by the positioning mechanism, when the positioning mechanism is placed in the placement slot, it is difficult to ensure that the staff places the positioning mechanism in the same position each time, so that the staff needs to adjust the support position by the adjustment mechanism each time they magnify and measure the relay contact, which is troublesome and reduces work efficiency;

[0005] Therefore, the present application proposes a relay contact amplification and measurement device. Utility Model Content

[0030] Embodiment 1

[0031] In order to solve the technical problems in the background technology, the following relay contact amplification and measurement device is provided:

When in use, the contact body 5 is clamped and positioned by the clamping mechanism 4, the contact body 5 is supplemented with light by the supplementary light 132, and the contact body 5 is imaged by the high-power camera 14 and displayed on the display screen 131, so that the size of the contact body 5 can be measured by observing the display screen 131.

[0033] By setting the mounting frame 2, the mounting block 3 and the clamping mechanism 4, the clamping mechanism 4 is positioned in the placement groove 121, so that the position of the clamping mechanism 4 is fixed, so that each time the staff enlarges and measures the contact body 5, when the contact body 5 is clamped and positioned by the clamping mechanism 4, the position of the contact body 5 will not change, and the staff does not need to adjust the position of the contact body 5, which facilitates the staff to measure the contact body 5 and improves work efficiency.

[0034] Embodiment 2

[0035] like Figure 1-Figure 6 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0036] In this embodiment, the clamping mechanism 4 includes a clamping plate 1 41 fixedly mounted on the bottom of the mounting block 3, a clamping plate 2 42 is hingedly connected to the bottom of the mounting block 3 and located on one side of the clamping plate 1 41, and a driving member 43 acting on the clamping plate 2 42 is installed on the mounting block 3, which is used to rotate the clamping plate 2 42 at the bottom of the mounting block 3 so that the clamping plate 1 41 and the clamping plate 2 42 are close to each other. When in use, when the contact body 5 is clamped and fixed, the clamping plate 2 42 is pressed against the contact body 5. Apply a force to make it rotate at the bottom of the mounting block 3 so that the clamping plate 42 moves away from the clamping plate 1 41. At this time, the state of the driving member 43 changes, and the end of the contact body 5 is inserted between the clamping plate 1 41 and the clamping plate 2 42. The force on the clamping plate 2 42 is cancelled, and the driving member 43 returns to its original state, so that the clamping plate 2 42 rotates and resets at the bottom of the mounting block 3, thereby the contact body 5 can be clamped and positioned by the clamping plate 1 41 and the clamping plate 2 42, which is convenient for use.

[0037] In this embodiment, the driving member 43 includes a fixed shaft 431 which is vertically fixedly mounted on the bottom of the mounting block 3, the clamping plate 42 is sleeved on the outside of the fixed shaft 431 and is hinged to the mounting block 3, a coil spring 432 is sleeved on the outside of the fixed shaft 431, and the two ends of the coil spring 432 are respectively fixedly connected to the fixed shaft 431 and the clamping plate 42. When in use, a force is applied to the clamping plate 42 to rotate at the bottom of the mounting block 3 so that the clamping plate 42 moves away from the clamping plate 41. The coil spring 432 is deformed by the force. When the force on the clamping plate 42 is cancelled, the coil spring 432 returns to its natural state, so that the clamping plate 42 can be rotated and reset at the bottom of the mounting block 3.

[0038] In this embodiment, a rubber pad 6 is fixedly installed on one side of the clamping plate 1 41 and the clamping plate 2 42 where they are close to each other.

[0039] Embodiment 3

[0040] like Figure 1-Figure 6 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0041] In this embodiment, the mounting frame 2 includes a fixing seat 21 detachably assembled on the support plate 12, and a positioning member 7 for fixing or canceling the fixing between the fixing seat 21 and the support plate 12 is installed on the support plate 12. A connecting rod 22 is installed on the top of the fixing seat 21, and the mounting block 3 is fixedly mounted on the bottom of the connecting rod 22 away from the fixing seat 21 by screws. The mounting block 3 is fixedly mounted on the bottom of the connecting rod 22 away from the fixing seat 21 by screws.

[0042] In this embodiment, the positioning member 7 includes a positioning rod 71 symmetrically hinged on the top of the support plate 12, and two through slots 211 are provided on the fixing seat 21. The two positioning rods 71 ​​can respectively pass through the two through slots 211 and be snapped with the fixing seat 21. When in use, when the fixing seat 21 is installed and positioned, the two through slots 211 on the fixing seat 21 are respectively sleeved on the outside of the two positioning rods 71. After the two positioning rods 71 ​​respectively pass through the two through slots 211, the two positioning rods 71 ​​are respectively rotated so that the two positioning rods 71 ​​are snapped with the fixing seat 21, thereby achieving the positioning effect between the fixing seat 21 and the support plate 12. Conversely, when the fixing seat 21 is disassembled, the two positioning rods 71 ​​are respectively rotated so that the two positioning rods 71 ​​can respectively pass through the two through slots 211, and the fixing seat 21 can be disassembled for easy use.

[0043] In this embodiment, a accommodating cavity 212 is provided in the fixing seat 21, a slot 213 connected to the accommodating cavity 212 is provided on the top of the fixing seat 21, a guide round rod 214 which can penetrate the slot 213 is movably installed on the fixing seat 21 and located in the accommodating cavity 212, a block 215 which is engaged with the slot 213 is fixed on the top of the guiding round rod 214, a spring 216 is sleeved on the outside of the guiding round rod 214, and the two ends of the spring 216 are respectively in conflict with the guiding round rod 214 and the inner top wall of the accommodating cavity 212. Specifically, a limiting plate is fixed at the bottom of the guiding round rod 214, and the two ends of the spring 216 are respectively in conflict with the limiting plate and the inner top wall of the accommodating cavity 212. The contact body 5 is fixed by the clamping mechanism 4. When the contact body 5 is measured, the connecting rod 22 is pulled Move upward, so that the block 215 is displaced to the top of the fixed seat 21, and the clamping mechanism 4 is displaced to the top of the support plate 12. At this time, the spring 216 is deformed, and then a force is applied to the connecting rod 22 to make it rotate around the guide round rod 214, so that the clamping mechanism 4 can be rotated to the outside of the machine base 1, thereby facilitating the clamping and positioning of the contact body 5. After the contact body 5 is clamped and positioned, a force is applied to the connecting rod 22 to make it rotate in the opposite direction around the guide round rod 214 and reset. Then the force on the connecting rod 22 is canceled, and the spring 216 returns to its natural state, so that the connecting rod 22 can be moved downward, so that the block 215 extends into the card slot 213 and is connected with the card slot, so that the connecting rod 22 can be positioned. Similarly, after the measurement of the contact body 5 is completed, it is convenient to cut the contact body 5.
