Description

Technical Field

[0001] This utility model relates to the field of inspection tool technology, and specifically to a mobile measuring mechanism used in inspection tools. Background Technology

[0002] Before and after the production of power battery casings, it is usually necessary to measure and inspect the parts of the battery casings using inspection tools to ensure the pass rate of the battery casing parts, thereby ensuring the safety and controllability of the casing assembly.

[0003] Currently, battery casings are typically inspected using a fixture, which includes a fixture base, a measuring tool, and a support. The measuring tool is mounted on the fixture base via the support, and the dimensions of the battery casing are inspected using the measuring tool.

[0004] However, due to the differences in battery casings among different types of power batteries and the large area that needs to be measured, the points that need to be measured by the gauge are located at different positions on the gauge base. This means that the measuring personnel need to adjust the position of the bracket used to mount the measuring instrument according to the measurement requirements. The adjustment of the bracket position inevitably involves the disassembly and assembly of the bracket, which increases the risk of the bracket being bumped or knocked, and also reduces the measurement efficiency of the gauge on the power battery casing. At the same time, the disassembly and assembly of the bracket can also easily affect its positional accuracy, thereby affecting the measurement accuracy. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a mobile measuring mechanism for gauges that eliminates the need to disassemble and reassemble the bracket used to mount the gauge, thereby improving measurement accuracy and gauge measurement efficiency.

[0006] A movable measuring mechanism for use with a gauge, the movable measuring mechanism being mounted on the gauge for measuring components on the gauge, includes a sliding assembly, a support assembly, a locking assembly, and a measuring tool. The sliding assembly is mounted on the gauge along a first direction and has a sliding degree of freedom along the first direction. The support assembly is mounted on the sliding assembly so that the support assembly can move along the first direction, and the support assembly has a plurality of mounting holes arranged along a second direction, the mounting holes extending along the height direction of the gauge. The locking assembly is mounted on the support assembly and at least partially has a movable degree of freedom to move along the height direction of the gauge, so that the locking assembly is locked to the gauge. The measuring tool is mounted on the support assembly to measure components on the gauge. The measuring tool can be selectively mounted on mounting holes at different positions to change the position of the measuring tool in the second direction. Furthermore, the first direction, the second direction, and the height direction of the gauge are perpendicular to each other.

[0007] Furthermore, the mounting holes include a first mounting hole and a second mounting hole, and along the height direction of the fixture, the top of the first mounting hole and the top of the second mounting hole have a height difference.

[0008] Furthermore, the support assembly includes a crossbeam and a gauge mounting bracket, the crossbeam being positioned above the gauge and having a gap between the crossbeam and the gauge; the gauge mounting bracket is mounted on the crossbeam, and mounting holes are formed in the gauge mounting bracket.

[0009] Furthermore, the crossbeam has an adjustment groove extending along the second direction, the gauge mounting bracket is connected to the adjustment groove, and the gauge mounting bracket has a degree of freedom of movement for adjustment relative to the second direction.

[0010] Furthermore, the bracket assembly also includes a mounting plate and a connecting column. The mounting plate is mounted on the sliding assembly, and the connecting column and the locking assembly are respectively mounted on the mounting plate. The connecting column extends along the height direction of the gauge, and the crossbeam is mounted on the top of the connecting column.

[0011] Furthermore, the moving measuring mechanism also includes a stop block disposed at the end of the sliding assembly along the first direction; the projection of the mounting plate along the first direction at least partially coincides with the projection of the stop block along the first direction.

[0012] Furthermore, the moving measuring mechanism also includes multiple locking blocks, which are mounted on the fixture along a first direction; the locking assembly is connected to the locking blocks so that the locking assembly locks with the fixture.

[0013] Furthermore, the locking assembly includes a locking rod arranged along the height direction of the fixture, the locking rod having a degree of freedom of movement along the height direction of the fixture; the locking block is formed with a socket, the locking rod is inserted into the socket, so that the locking assembly and the locking block are locked.

[0014] Furthermore, the support assembly is equipped with a handle for applying force to the support assembly.

[0015] Furthermore, the moving measuring mechanism also includes a gauge zeroing seat, which is mounted on the gauge; the moving measuring mechanism moves along a first direction including an initial position and an end position, and the moving measuring mechanism moves between the initial position and the end position; the gauge zeroing seat is located on one side of the initial position.

[0016] The sliding assembly allows the support assembly to move relative to the gauge along a first direction, thereby enabling the gauge mounted on the support assembly to be translated without disassembling the support assembly used to mount the gauge, thus improving measurement accuracy and gauge measurement efficiency.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the gauge is used to inspect the dimensions of certain parts (battery casing). Different sized parts are placed on the gauge, and the locations of the dimensions to be inspected vary. To facilitate adapting to the dimensional inspection needs of different parts or the inspection needs of different locations of the same part, this embodiment provides a movable measuring mechanism for the gauge, enabling the gauge 1 to measure and inspect the dimensions of different parts.

[0023] like Figure 1 and Figure 2 As shown, as one implementation, a movable measuring mechanism is used for a fixture. The movable measuring mechanism is mounted on the fixture 1, and the movable measuring mechanism is at least partially movable relative to the fixture 1 in order to move the movable measuring mechanism to the position to be measured.

[0024] The movable measuring mechanism includes a sliding assembly 2, a support assembly 3, a locking assembly 4, and a measuring tool 5. The sliding assembly 2 is mounted on the fixture 1 along a first direction and has a sliding degree of freedom along the first direction. The support assembly 3 is mounted on the sliding assembly 2 so that the support assembly 3 can move along the first direction. The locking assembly 4 is mounted on the support assembly 3 and has at least a partial degree of freedom of movement along the height direction of the fixture 1. Through the relative movement of the locking assembly 4, the locking assembly 4 is locked to the fixture 1, thereby locking the support assembly 3 onto the fixture 1. The measuring tool 5 is mounted on the support assembly 3. By moving the support assembly 3, the measuring tool 5 moves to the position where the dimension needs to be measured, thereby measuring the parts on the fixture 1 through the measuring tool 5. There is no need to disassemble and assemble the support assembly used to mount the measuring tool, which improves the measurement accuracy and the measurement efficiency of the fixture.

[0025] The bracket assembly 3 has a plurality of mounting holes 3-1 arranged along the second direction. The mounting holes 3-1 extend along the height direction of the gauge 1. The gauge 5 is mounted on the bracket assembly 3 through the mounting holes 3-1, and the measuring part of the gauge 5 extends at least partially out of the lower end of the mounting hole 3-1 so as to facilitate the measurement of the part's dimensions through the measuring part of the gauge 5.

[0026] Furthermore, the measuring tool 5 can be selectively mounted in the mounting holes 3-1 at different positions to change the position of the measuring tool 5 in the second direction. The position of the measuring tool 5 in the first direction is adjusted by moving the bracket assembly 3 relative to the gauge 1, and the position of the measuring tool 5 in the second direction is adjusted by mounting the measuring tool 5 in the mounting holes 3-1 at different positions.

[0027] The first direction, the second direction, and the height direction of gauge 1 are all perpendicular to each other.

[0028] To facilitate a clearer description of the technical solution of this application, the following definitions are provided. Figure 1 The directions shown are up, down, left, right, front, and back. The first direction refers to... Figure 1 The front and back directions, the second direction refers to Figure 1 The left and right directions in the middle, and the height direction of gauge 1 refers to Figure 1 The up and down directions in the middle.

[0029] As one implementation, two sliding components 2 are installed on the upper surface of the fixture 1, and the two ends of the support component 3 are slidably installed on the fixture 1 through the sliding components 2, so that the support component 3 can be translated along the first direction.

[0030] The sliding assembly 2 includes a slide rail 2-1 and a slider 2-2. The slide rail 2-1 is fixed on the fixture 1 and the extension direction of the slide rail 2-1 is parallel to the first direction. The slider 2-2 is mounted on the slide rail 2-1 and has a degree of freedom to move along the slide rail 2-1.

[0031] The bracket assembly 3 is installed on the slider 2-2. The slider 2-2 can be moved relative to the slide rail 2-1 by applying an external force to the slider 2-2 or the bracket assembly 3, thereby realizing the movement of the bracket assembly 3.

[0032] It should be noted that this implementation does not involve structural improvements to slide rail 2-1 and slider 2-2.

[0033] like Figure 2 and Figure 3As shown, in one implementation, the bracket assembly 3 includes a crossbeam 3-4, a gauge mounting bracket 3-5, a mounting plate 3-7, and a connecting column 3-8. The mounting plate 3-7 is mounted above the slider 2-2. The crossbeam 3-4 is connected to the mounting plate 3-7 via the connecting column 3-8. The gauge mounting bracket 3-5 is mounted on the crossbeam 3-4, and the gauge 5 is mounted on the gauge mounting bracket 3-5.

[0034] Among them, the connecting column 3-8 extends along the height direction of the gauge 1, and the crossbeam 3-4 is installed on the top of the connecting column 3-8.

[0035] Furthermore, the height of the connecting column 3-8 should be greater than the height of the component to be tested, so that the crossbeam 3-4 is above the gauge 1, and there is a gap between the crossbeam 3-4 and the gauge 1, to prevent interference between the crossbeam 3-4 or the gauge 5 installed on the crossbeam 3-4 and the component to be tested during the movement of the support assembly 3 in the first direction.

[0036] As one implementation method, multiple mounting holes 3-1 are uniformly formed on the gauge mounting bracket 3-5.

[0037] Specifically, the bracket assembly 3 includes a plurality of gauge mounting brackets 3-5, which are respectively mounted on the crossbeam 3-4. Each gauge mounting bracket 3-5 has at least one mounting hole 3-1, such that the mounting holes 3-1 are arranged along the second direction.

[0038] Alternatively, the bracket assembly 3 may include a gauge mounting bracket 3-5, on which a plurality of mounting holes 3-1 are formed along a second direction.

[0039] It should be noted that this implementation is described with the bracket assembly 3 including multiple gauge mounting brackets 3-5. The arrangement of multiple gauge mounting brackets 3-5 facilitates the appropriate adjustment of the position of some mounting holes 3-1 in the second direction, thereby making it easier for the gauge 5 to be aligned with the position to be measured by the component.

[0040] As one implementation, the crossbeam 3-4 has an adjustment groove 3-6 extending in the second direction. The measuring tool mounting bracket 3-5 is connected to the adjustment groove 3-6, and the measuring tool mounting bracket 3-5 has a degree of freedom of movement relative to the second direction. That is, the mounting bracket 3-5 can be adjusted in the second direction relative to the crossbeam 3-4 through the adjustment groove 3-6, thereby appropriately adjusting the position of some mounting holes 3-1 in the second direction, so that the measuring tool 5 is aligned with the position to be measured by the component.

[0041] As one implementation, the mounting hole 3-1 includes a first mounting hole 3-2 and a second mounting hole 3-3. Along the height direction of the gauge 1, there is a height difference between the top of the first mounting hole 3-2 and the top of the second mounting hole 3-3. That is, there is a height difference between the gauge 5 installed in the first mounting hole 3-2 and the gauge 5 installed in the second mounting hole 3-3, so as to adapt to the detection needs of different heights at different detection positions.

[0042] It should be noted that, in this implementation, the top height of the mounting hole 3-1 includes, but is not limited to, two types. The top height of the mounting hole 3-1 at different detection positions can be designed according to actual detection requirements in order to meet different detection needs.

[0043] As one implementation, a handle 3-9 is installed on the bracket assembly 3. The handle 3-9 is used to apply force to the bracket assembly 3 so as to drive the bracket assembly 3 to slide.

[0044] Specifically, handle 3-9 can be installed on crossbeam 3-4 or connecting post 3-8.

[0045] In one implementation, the projected area of ​​the mounting plate 3-7 along the height direction of the fixture 1 is greater than the projected area of ​​the slider 2-2 along the height direction of the fixture 1. That is, the mounting part 3-7 extends at least partially to the outer edge of the slider 2-2, and the locking component 4 is installed on the outside of the mounting plate 3-7 extending to the slider 2-2, so that the locking component 4 faces the fixture 1 so that the locking component 4 abuts against the fixture 1, thereby locking the sliding component 2 and fixing the bracket component 3.

[0046] like Figure 2 and Figure 3 As shown, in one implementation, the locking assembly 4 includes a locking bracket 4-2 and a locking rod 4-1. The locking bracket 4-2 is mounted on the mounting plate 3-7, and the locking rod 4-1 is installed in the locking bracket 4-2 in a liftable manner, and the locking rod 4-1 is arranged along the height direction of the inspection tool 1.

[0047] The locking rod 4-1 has a degree of freedom to move along the height direction of the fixture 1. After the locking rod 4-1 descends, it abuts against the fixture 1, thereby locking the locking component 4 and the fixture 1, thus locking the sliding component 2, and fixing the bracket component 3.

[0048] As one implementation, the locking assembly 4 also includes a handle 4-3. One end of the handle 4-3 is rotatably mounted on the locking bracket 4-2 via a pivot. An oblong hole is formed in the middle of the handle 4-3. The top of the locking rod 4-1 is connected to the oblong hole via a connecting shaft, so that the locking rod 4-1 can be driven to rise and fall by the handle 4-3, thereby facilitating the locking assembly 4 to lock with the inspection tool 1.

[0049] As one implementation, the moving measuring mechanism also includes a plurality of locking blocks 7, which are mounted on the gauge 1 and arranged along a first direction.

[0050] The locking assembly 4 includes a locked state and an active state. When the locking assembly is in the locked state, the locking assembly 4 is connected to the locking block 7 so that the locking assembly 4 is locked to the fixture 1. When the locking assembly is in the active state, the locking assembly 4 is separated from the locking block 7 so that the bracket assembly 3 can slide relative to the fixture 1.

[0051] Specifically, the locking block 7 has a socket 7-1. When the locking assembly is in the locked state, the locking rod 4-1 is inserted into the socket 7-1 to lock the locking assembly 4 and the locking block 7. When the locking assembly is in the active state, the locking rod 4-1 is separated from the socket 7-1 so that the bracket assembly 3 can slide relative to the inspection fixture 1.

[0052] Alternatively, the moving measuring mechanism includes a locking block 7, which is elongated and extends along a first direction, and a plurality of insertion holes 7-1 are formed within the locking block 7.

[0053] It should be noted that this implementation is described with the moving measuring mechanism including multiple locking blocks 7. At the same time, the multiple locking blocks 7 can more accurately adjust the position of one or more sockets 7-1 along the first direction, so as to meet the detection requirements of different positions of the component under test.

[0054] As one implementation method, the locking block 7 is located on the outside of the sliding assembly 2 to prevent the locking block 7 from interfering with the component to be inspected, while also improving the ease of installation of the locking block 7.

[0055] As one implementation, the moving measuring mechanism also includes two stops 6, which are respectively arranged at the ends of the sliding component 2 along the first direction, and are used to limit the sliding stroke of the support component 3.

[0056] Specifically, the projection of the mounting plate 3-7 along the first direction at least partially coincides with the projection of the stop block 6 along the first direction, so that when the bracket assembly 3 moves to the foremost or rearmost end, the mounting plate 3-7 abuts against the stop block 6, thereby limiting the sliding stroke of the bracket assembly 3.

[0057] like Figure 1 As shown, in one implementation, the mobile measuring mechanism also includes a gauge zeroing seat 8, which is installed on the gauge 1. The gauge zeroing seat 8 is used to zero the gauge 5 to ensure the accuracy of the measurement of the gauge 5.

[0058] The moving measuring mechanism moves along a first direction, including an initial position and an end position, and moves between the initial position and the end position.

[0059] When the moving measuring mechanism is in the initial position, the slider 2-2 of the moving component 2 is located at the initial position of the slide rail 2-1; when the moving measuring mechanism is in the end position, the slider 2-2 of the moving component 2 is located at the end position of the slide rail 2-1.

[0060] The gauge zeroing seat 8 is located on one side of the initial position. Specifically, the gauge zeroing seat 8 is located in front of the initial position so that the gauge 5 can be zeroed before the measurement begins, and the zeroed gauge 5 can be installed on the bracket assembly 3 to improve the ease of use of the mobile measuring mechanism.

[0061] It should be noted that the measuring instrument 5 is a dial indicator or a micrometer indicator, and the zeroing seat 8 is used to zero the measuring instrument 5. This application does not involve any improvement to the zeroing seat 8.

[0062] Finally, it should be noted that the above are only some preferred embodiments of this application and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
