Detailed Embodiments

[0022] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] As Figure 1-6 As commonly shown, this embodiment relates to a test device for automatic laser ranging, which meets multi-scenario simulation test experiments. Specifically, it includes a slide table 5 powered by a driving motor 6. A needle gauge fixing module 9, an edge measurement fixing module 10, a gap measurement fixing module 11, and a breakage measurement fixing module 12 are detachably installed on the slide table 5. Therefore, in this embodiment, different modules are replaced to realize the tests of outer diameter, edge, gap, and breakage. It should be noted that on this basis, this embodiment can also carry other modules to meet more simulation test experiments;

[0024] On this basis, sensor fixing aluminum blocks 2 are arranged on both sides of the slide table 5 and are installed on the breadboard 4 below the slide table 5 to respectively assemble sensors 1. The sensors 1 are adapted to the needle gauge fixing module 9, the edge measurement fixing module 10, the gap measurement fixing module 11, and the breakage measurement fixing module 12 by changing the orientation and assembly height under external force. It should be noted that the test pieces and heights of the needle gauge fixing module 9, the edge measurement fixing module 10, the gap measurement fixing module 11, and the breakage measurement fixing module 12 are not the same. Therefore, when replacing the modules, it is necessary to adapt and adjust the orientation setting and setting height of the sensors 1 to further improve the test accuracy.

[0025] The distance between the two sensors 1 is 10 - 30 cm, and the change in the distance meets the adaptation conditions of various simulation test experiments; preferably, the sensors 1 are threadedly connected to the top surface of the sensor fixing aluminum blocks 2 or are threadedly connected to the top surface of the sensor fixing aluminum blocks 2 through vertical fixing members 8. Therefore, it can be understood that threaded holes are provided on the top surface of the sensor fixing aluminum blocks 2.

[0026] The sensor fixing aluminum blocks 2 are fastened to the breadboard 4 through a plurality of aluminum block L-shaped fixing members 3 provided on both sides thereof. In this embodiment, the sides where the aluminum block L-shaped fixing members 3 are provided are opposite to each other. The aluminum block L-shaped fixing members 3 are L-shaped bent plates. One side plate of the aluminum block L-shaped fixing member 3 is threadedly connected to the sensor fixing aluminum block 2, and the other side plate is threadedly connected to the breadboard 4, thus completing the connection of the sensor fixing aluminum block 2 to the breadboard 4.

[0027] The number of breadboards 4 is multiple. The multiple breadboards 4 are distributed and arranged along the length extension direction of the slide table 5 to jointly support the slide table 5. In this embodiment, the number of breadboards 4 is three. A number of screw holes are also provided on the breadboards 4, and the screw holes are used for the threaded connection of the sensor fixing aluminum blocks 2 and the slide table 5.

[0028] Based on the above structure, the sliding table 5 is fastened to the breadboard 4 by a plurality of L-shaped fixing members 7 of the sliding table arranged on both sides thereof. The L-shaped fixing member 7 of the sliding table is an L-shaped bent plate. One side plate of the L-shaped fixing member 7 of the sliding table is threadedly connected to the sliding table 5, and the other side plate is threadedly connected to the breadboard 4.

[0029] The driving motor 6 is arranged at one free end of the sliding table 5. It should be noted that the driving motor 6 is a prior art.

[0030] Embodiment 1

[0031] Based on the above structure, the needle gauge fixing module 9 is fastened to the sliding table 5 of this embodiment by screws, and the outer diameter measurement is realized by controlling the speed and position of the sliding table 5. It should be noted that this control is not the technical solution to be protected by this application.

[0032] As Figure 3 shown, the needle gauge fixing module 9 includes a plurality of needle gauges fixed on the fixing member at equal intervals. The distance between any two needle gauges is 25 mm to ensure that the sensor 1 can detect outer diameters of different sizes. When replacing the needle gauge fixing module 9 for outer diameter testing, the sensor 1 is directly threadedly connected to the top surface of the sensor fixing aluminum block 2.

[0033] Embodiment 2

[0034] The edge measurement fixing module 10 is fastened to the sliding table 5 of this embodiment by screws, and the outer diameter measurement is realized by controlling the speed and position of the sliding table 5. It should be noted that this control is not the technical solution to be protected by this application.

[0035] As Figure 4 shown, a detection step is formed on the measuring member of the edge measurement fixing module 10. The edge measurement fixing module 10 measures the accuracy of the edge by the edge of the detection step shape to ensure that the edge measurement accuracy of the sensor 1 can reach ±5 mm. When replacing the edge measurement fixing module 10 for edge testing, the sensor 1 is vertically arranged and threadedly connected to the top surface of the sensor fixing aluminum block 2 through the vertical fixing member 8. The sensor 1 is vertically threadedly connected to one side surface of the vertical fixing member 8, and the other side surface of the vertical fixing member 8 is threadedly connected to the top surface of the sensor fixing aluminum block 2.

[0036] Embodiment 3

[0037] The clearance measurement fixing module 11 is fastened to the sliding table 5 of this embodiment by screws, and the outer diameter measurement is realized by controlling the speed and position of the sliding table 5. It should be noted that this control is not the technical solution to be protected by this application.

[0038] As Figure 5As shown, the gap measurement fixing module 11 measures the accuracy of the gap by detecting the gap size between two squares to ensure that the sensor 1 can detect gaps of different sizes. When replacing the gap measurement fixing module 11 for gap testing, the sensor 1 is vertically arranged and threadedly connected to the top surface of the sensor fixing aluminum block 2 through the vertical fixing member 8. The sensor 1 is vertically threadedly connected to one side surface of the vertical fixing member 8, and the other side surface of the vertical fixing member 8 is threadedly connected to the top surface of the sensor fixing aluminum block 2.

[0039] Embodiment 4

[0040] In this embodiment, the damage measurement fixing module 12 is fastened to the sliding table 5 by screws, and the damage test is realized by controlling the speed and position of the sliding table 5. It should be noted that this control is not the technical solution to be protected by this application.

[0041] As Figure 6 shown, the damage measurement fixing module 12 simulates the detection of battery film damage. The gap between two squares represents the damage size to ensure that the sensor 1 can detect the smallest damage gap. When the damage measurement fixing module 12 conducts the damage test, the sensor 1 is vertically arranged and threadedly connected to the top surface of the sensor fixing aluminum block 2 through the vertical fixing member 8. The sensor 1 is vertically threadedly connected to one side surface of the vertical fixing member 8, and the other side surface of the vertical fixing member 8 is threadedly connected to the top surface of the sensor fixing aluminum block 2.

[0042] This application discloses a test device for automatic laser ranging, with a simple and reasonable structure. It is assembled and fixed by screws, which is convenient for disassembly and assembly. The tests of outer diameter, edge, gap, and damage are realized through the position change in the horizontal and vertical directions and the cooperation of different modules. Similarly, it can meet multi-scenario simulation test experiments.

[0043] The above embodiments are not limitations on the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the technical scope of the present utility model also fall within the protection scope of the present utility model.
