As described in the background of the utility model, in the prior art, the calibration fixture generally includes a top plate assembly and a bottom plate assembly that are arranged at intervals, and the top plate assembly is fixed relative to the bottom plate assembly, i.e. the height of the fixture is fixed, and in addition, a docking assembly for docking with a contact assembly on the charging and discharging device is generally disposed on the top plate assembly. When the charging and discharging equipment is detected and calibrated, the whole tool is required to be placed on the mounting position of the battery tray on the charging and discharging equipment, so that the butt joint assembly on the tool is in butt joint with the contact assembly on the charging and discharging equipment, and certain determined states of the charging and discharging equipment are detected and calibrated, for example, the charging and discharging equipment can be compatible with a plurality of different batteries, and the certain determined states refer to corresponding states of the charging and discharging equipment when the charging and discharging equipment charges and discharges the battery at one height.

In order to ensure the butt joint of the butt joint assembly on the tool and the contact assembly on the charging and discharging equipment, when the charging and discharging equipment is in a certain state, the tool with certain height can be usually only adapted, and when the charging and discharging equipment is in a different state, the tool with different height needs to be adapted, and because the whole height of the certain tool is fixed, the same tool can only detect and calibrate the charging and discharging equipment in a certain state, and when the charging and discharging equipment in a different state is detected and calibrated, the power supply calibration tool with different height needs to be equipped, so that the cost is increased.

In view of the above-mentioned problems, the embodiment of the utility model provides a power calibration tool to solve the problem that in the prior art, the charging and discharging equipment in different states cannot be detected and calibrated due to the fixed overall height of the tool.

The technical scheme of the utility model will be further described with reference to specific embodiments and drawings.

Fig. 1 is a front view (not shown) of a power calibration tool according to an embodiment of the present utility model, fig. 2 is a right side view (not shown) of the power calibration tool of fig. 1, and fig. 3 is a top view of the power calibration tool of fig. 1.

As shown in fig. 1-3, the power calibration fixture includes a first docking assembly 50 and a fixture docking mechanism including a bottom plate assembly 10, a top plate assembly 20, and a lift drive assembly 30. The top plate assembly 20 and the bottom plate assembly 10 are disposed at intervals along a first direction (Z-axis direction in fig. 1), and the top plate assembly 20 is used for providing a first docking assembly 50 for docking with a first contact assembly (not shown in the drawing) of the charging and discharging device, and the lifting driving assembly 30 is respectively connected with the bottom plate assembly 10 and the top plate assembly 20, and is used for driving the bottom plate assembly 10 and the top plate assembly 20 to be relatively close to or relatively far away from each other along the first direction.

In the embodiment of the utility model, when the power calibration fixture is used for detecting and calibrating the charging and discharging equipment, as the charging and discharging equipment in different states can only be matched with the fixture docking mechanism with different heights, when the charging and discharging equipment is in a certain determined state, the bottom plate assembly 10 and the top plate assembly 20 can be driven by the lifting driving assembly 30 to be relatively close to or relatively far away from each other along the first direction so as to adjust the distance between the bottom plate assembly 10 and the top plate assembly 20, and as the first docking assembly 50 is arranged on the top plate assembly 20, when the distance between the bottom plate assembly 10 and the top plate assembly 20 can be adjusted, the distance between the first docking assembly 50 and the bottom plate assembly 10 can be adjusted, so that the height of the fixture docking mechanism can be matched with the charging and discharging equipment in a certain determined state, and further, the first docking assembly 50 can be conveniently docked with the first contact assembly, and the distance between the top plate assembly 20 and the bottom plate assembly 10 can be adjusted by the lifting driving assembly 30 so that the power calibration fixture can be used for detecting the charging and discharging equipment in different states, thereby being beneficial to enhancing the power calibration fixture compatibility, and meanwhile, the power calibration fixture has no need to be provided with different heights, and is beneficial to reducing the cost.

It should be noted that the tool docking mechanism is not limited to be applied to a power calibration tool, but can be applied to other types of tools, for example, the tool docking mechanism can be applied to a negative pressure plugging tool, a temperature calibration tool and a dotting tool, and other tools for detecting and calibrating a charging and discharging device.

Further, the base plate assembly 10 is configured to provide a second docking assembly 40 for docking with a second contact assembly (not shown) on the charging and discharging apparatus. The distance between the first contact member and the second contact member is determined when the charge and discharge device is in a certain state, and the distance between the first contact member and the second contact member is different when the charge and discharge device is in a different state. Therefore, in order to ensure the docking of the contact assembly and the docking assembly, when the power calibration fixture is used to detect and calibrate the charging and discharging device, the distance between the first docking assembly 40 and the second docking assembly 50 can be adjusted by the lifting driving assembly 30 according to the distance between the first contact assembly and the second contact assembly in a certain determined state, so as to adapt the distance between the docking assemblies to the distance between the contact assemblies, thereby facilitating the docking of the corresponding docking assemblies with the corresponding contact assemblies.

By arranging the second docking assembly 40 for docking with the second contact assembly on the charging and discharging device on the bottom plate assembly 10, the tool docking mechanism can be applied to tools which are required to be docked with the contact assemblies on two sides corresponding to the top plate assembly 20 and the bottom plate assembly 10, and thus the applicability can be enhanced.

It should be noted that in some exemplary embodiments, when the tool docking mechanism is applied in a power calibration tool, the first docking assembly 50 and the second docking assembly 40 may be understood as electrode taking columns. Of course, in other exemplary embodiments, the docking assembly may be understood as having other understandings, such as, for example, a negative pressure docking nozzle when the tool docking mechanism is applied to a negative pressure blockage measuring tool, or a temperature probe when the tool docking mechanism is applied to a temperature calibration tool, and a copy when the tool docking mechanism is applied to a dotting tool. The docking assembly is specifically configured as the first docking assembly 50 or the second docking assembly 40, or as both the first docking assembly 50 and the second docking assembly 40, and needs to be determined according to the specific tool type. For example, in the negative pressure plugging tool, the docking assembly is set as the first docking assembly 50; in the temperature calibration fixture, the docking assembly may be provided as a first docking assembly 50 or the docking assembly may be provided as a second docking assembly 40; in the dotting tool, the docking assembly is provided as a first docking assembly 50 and a second docking assembly 40.

Further, as shown in fig. 4 and 5, for the bottom plate assembly 10, the bottom plate assembly 10 includes a support plate 11 and a floating plate 12 stacked in a first direction, the floating plate 12 is located on a side of the support plate 11 facing away from the top plate assembly 20, the floating plate 12 is disposed on the support plate 11 in a first direction in a liftable manner, and the floating plate 12 is provided with a relief hole 13 penetrating the floating plate 12 in the first direction. The supporting plate 11 is provided with a second docking assembly 40 which is in docking with a second contact assembly on the charging and discharging equipment, and the avoidance hole 13 is used for enabling the second contact assembly to pass through the avoidance hole 13 to dock with the second docking assembly 40.

When the second contact assembly is set to the probe assembly, in the process of docking the second contact assembly with the second docking assembly 40, the tool is easily jacked up because the elasticity of the second contact assembly is larger than the weight of the whole tool, and a travel switch on the charging and discharging equipment cannot sense the tool, so that the positioning of the tool cannot be accurately realized. Because floating plate 12 liftable ground sets up on backup pad 11, and because second interfacing assembly 40 sets up on backup pad 11, like this when second contact assembly and second interfacing assembly 40 dock, backup pad 11 can be jacked, upwards moves and keeps away from floating plate 12, and floating plate 12's position is unaffected, can make the travel switch on the charge-discharge equipment sense the frock, realizes the accurate positioning of whole frock position, and then can guarantee each electrode column subassembly of getting and the accurate butt joint between corresponding each probe subassembly, ensures the normal operating of equipment.

In order to make the floating plate 12 more stable and stable to run when lifting and lowering in the first direction relative to the support plate 11, in some embodiments, a guiding connection structure is provided between the support plate 11 and the floating plate 12, the guiding connection structure being used for achieving fixation between the support plate 11 and the floating plate 12, and for guiding the support plate 11 and the floating plate 12 to be relatively close to or relatively far away from each other in the first direction.

The support plate 11 and the floating plate 12 can be connected and fixed through the guide connection structure, so that the support plate 11 and the floating plate 12 can form a whole, the support plate 11 and the floating plate 12 are convenient to set and install, the support plate 11 and the floating plate 12 can be relatively close to or relatively far away from the guide, the movement direction between the support plate 11 and the floating plate 12 is guaranteed, and the floating plate 12 can move more stably and more stably relative to the support plate 11 in the lifting process of the first direction.

As for the guide connection structure, specifically, as shown in fig. 5 and 6, the guide connection structure includes positioning shafts 14 disposed on the floating plate 12, positioning holes (not labeled in the drawing) disposed on the supporting plate 11 and matched with the positioning shafts 14 in an up-down guide manner, and the positioning shafts 14 are provided with four, each positioning shaft 14 is respectively fixed at four corners of the floating plate 12, correspondingly, the positioning holes are also provided with four, each positioning hole is respectively disposed at four corners of the supporting plate 11, and is respectively disposed corresponding to each positioning shaft 14 up-down.

The guide connecting structure is arranged as the positioning shaft 14 and the positioning hole, so that the guide connecting structure can be guaranteed to be relatively close to or relatively far away from the support plate 11 and the floating plate 12 through the guide fit between the positioning shaft 14 and the positioning hole, the structural form of the guide connecting structure is simplified, and the guide connecting structure is convenient to process and manufacture.

Through setting the quantity of locating shaft 14 and locating hole to four, each locating shaft 14 is fixed respectively at four corners of floating plate 12, and each locating hole sets up respectively at four corners of backup pad 11, can make four corners of floating plate 12 all receive the direction effect from the direction connection structure, and then makes floating plate 12 more stable when going up and down along the first direction for backup pad 11.

Of course, the number of the positioning shafts 14 and the positioning holes is four, which is only one possible implementation shown in the embodiment of the present utility model, and in other possible implementations, the number of the positioning shafts 14 and the positioning holes may be other values, for example, the number of the positioning shafts 14 and the positioning holes may be two, three, etc., and the embodiment of the present utility model is not limited to the number of the positioning shafts 14 and the positioning holes.

When two positioning shafts 14 and two positioning holes are provided, the two positioning shafts 14 may be located at two diagonally disposed corners of the floating plate 12, and correspondingly, the two positioning holes may be located at two diagonally disposed corners of the supporting plate 11.

When the positioning shafts 14 are provided in two, and the two positioning shafts 14 are diagonally arranged, the number of the positioning shafts 14 can be reduced as much as possible while ensuring the stability of the movement between the support plate 11 and the floating plate 12, thereby playing a role in reducing the cost of the guide connection structure.

For the top plate assembly 20, referring to fig. 1, 2 and 3, the top plate assembly 20 includes a mounting plate 21 and a fixing plate 22 fixedly connected above the mounting plate 21, the mounting plate 21 is connected with a lifting driving assembly 30, the fixing plate 22 is used for setting a first docking assembly 50 docking with a first contact assembly on a charging and discharging device, the fixing plate 22 is further provided with a power taking switching assembly 60, and the power taking switching assembly 60 is used for docking with a power taking port in the charging and discharging device so as to realize power supply to a power supply calibration tool.

Since the fixing plate 22 is fixedly connected above the mounting plate 21, the mounting plate 21 is connected with the lifting driving assembly 30, and therefore the lifting driving assembly 30 can drive the mounting plate 21 to move, and further can drive the fixing plate 22 to move. Because the fixing plate 22 is used for setting the first docking assembly 50, when the lifting driving assembly 30 drives the fixing plate 22 to move, the first docking assembly 50 can be driven to move, and then the first docking assembly 50 can be well matched with the first contact assembly of the charging and discharging equipment in a certain determined state.

When the top plate assembly 20 includes the mounting plate 21 and the fixed plate 22 fixedly connected above the mounting plate 21, the mounting plate 21 can be specially used for being connected with the lifting driving assembly 30, and the fixed plate 22 is specially used for setting the first docking assembly 50, that is, the first docking assembly 50 and the lifting driving assembly 30 are respectively arranged on different parts, compared with the mode that the first docking assembly 50 and the lifting driving assembly 30 are uniformly distributed on the same part, the possibility of interference of the first docking assembly 50 and the lifting driving assembly 30 can be reduced to a certain extent, and the difficulty of layout can be reduced to a certain extent.

As shown in fig. 1, 2 and 7, the lift driving assembly 30 is located between the bottom plate assembly 10 and the top plate assembly 20 and is disposed on the bottom plate assembly 10, and the lift driving assembly 30 has a liftable output end connected to the top plate assembly 20.

The lifting drive assembly 30 is arranged between the bottom plate assembly 10 and the top plate assembly 20, so that the arrangement among the lifting drive assembly 30, the bottom plate assembly 10 and the top plate assembly 20 is more compact, the occupied space of the three can be reduced, and the arrangement of the three is facilitated.

While the above-mentioned lift drive assembly 30 is disposed between the base plate assembly 10 and the top plate assembly 20, disposing the lift drive assembly 30 on the base plate assembly 10 is only one possible implementation of the embodiment of the present utility model, and in another possible implementation, the lift drive assembly 30 may be disposed on the top plate assembly 20, where the output end of the lift drive assembly 30 is connected to the base plate assembly 10. The arrangement of the lifting driving assembly 30 is enriched, and the lifting driving assembly 30 is further convenient to arrange and install.

It should be noted that the above-mentioned lifting drive assembly 30 is located between the bottom plate assembly 10 and the top plate assembly 20 only as one possible way of illustrating the embodiment of the present utility model, and in another possible implementation, the lifting drive assembly 30 may be located outside the bottom plate assembly 10 and the top plate assembly 20. Since the outer space of the floor assembly 10 and the ceiling assembly 20 is relatively large, the lifting driving assembly 30 is disposed at the outer sides of the floor assembly 10 and the ceiling assembly 20, thereby facilitating the installation of the lifting driving assembly 30.

There are various implementations of the above-mentioned lifting drive assembly 30, and in a first possible implementation, referring to fig. 1, 2 and 7, the lifting drive assembly 30 includes a worm wheel 33 and a worm 32 meshed with each other, and a screw 34 connected to the worm wheel 33 and liftable along a first direction. Wherein, lead screw 34 extends along first direction, and the output is provided in lead screw 34, and worm 32 is connected with input shaft 35.

In this implementation, since the worm 32 is connected with the input shaft 35, the worm wheel 33 and the worm 32 are engaged with each other, and thus, when the worm 32 is rotated by the input shaft, the worm wheel 33 can be rotated. Since the screw 34 is connected to the worm wheel 33 and is liftable in the first direction, the screw 34 can be driven to rise and fall in the first direction after the worm wheel 33 starts to rotate.

After the screw 34 is lifted along the first direction, the output end is disposed on the screw 34, so that the output end is driven to lift along the first direction, and the bottom plate assembly 10 and the top plate assembly 20 can be driven to be relatively close to or relatively far away from each other along the first direction.

Wherein, when the elevation driving assembly 30 includes the worm wheel 33 and the worm 32 engaged with each other, since the movement reliability of the worm wheel 33 and the worm 32 is high and a large force can be transmitted, it is possible to ensure that the elevation driving assembly 30 can transmit a large force while ensuring that the elevation driving assembly 30 has a high reliability.

Of course, the lifting driving assembly 30 may be implemented by other possible structures, and the purpose of driving the bottom plate assembly 10 and the top plate assembly 20 to relatively approach or relatively separate in the first direction need only be achieved, which is not limited by the embodiment of the present utility model.

In a second possible implementation, the lifting drive assembly 30 is an electric cylinder, and the telescopic rod on the output end of the electric cylinder can output up-and-down motion, and the output end of the lifting drive assembly 30 is arranged on the telescopic rod. Because the electric cylinder technology is mature and the structure is simple, the structure of the lifting driving assembly 30 can be simplified while the operation reliability of the lifting driving assembly 30 is ensured.

In a third possible implementation manner, the lifting driving assembly 30 is an air cylinder or a hydraulic cylinder, and no matter what implementation manner the lifting driving assembly 30 is, as long as the lifting driving assembly can drive the bottom plate assembly 10 and the top plate assembly 20 to relatively approach or relatively separate along the first direction, the implementation manner of the lifting driving assembly 30 is not listed any more in this embodiment of the present utility model.

When the drop drive assembly 30 is the first possible implementation described above, the input shaft 35 is used to removably attach the crank 70, as shown in fig. 1, 2 and 5.

Because the rocking handle 70 is detachably connected with the input shaft, the rocking handle 70 can be used for driving the input shaft to rotate, so that the humanization degree is higher, and the manual operation is more convenient.

By detachably connecting the crank 70 to the input shaft, the crank 70 can be mounted to or dismounted from the input shaft as desired, which is very flexible and convenient.

In some embodiments, as shown in fig. 8, the rocker arm 70 includes a rocker arm 71 and a crank handle 72 connected to the rocker arm 71, a boss 73 is provided on the rocker arm 71, a placement seat 80 is provided on the base plate assembly 10, and a first receiving hole 81 for receiving the boss 73 and a second receiving hole 82 for receiving the crank handle 72 are provided on the placement seat 80.
