Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0025] Example 1: The purpose of this device is to detect the dimensions of the cabinet chassis so that the measured dimensions of the sheet metal parts can be compared with the preset dimensions, and the processing parameters can be adjusted in a timely manner to ensure the dimensional accuracy of the products.

[0026] like Figure 1 , Figure 2 and Figure 6 As shown, this embodiment 1 provides a sheet metal cabinet chassis size detection device based on laser ranging, including a base 1, a support frame 2, a detection component and an L-shaped positioning block 4. The base 1 has an arc-shaped hole 3, and the support frame 2 is slidably limited in the arc-shaped hole 3. Further, a sliding rod that matches the shape of the arc-shaped hole 3 is provided at the arc-shaped hole 3. The bottom of the support frame 2 is connected to a slider and sleeved on the sliding rod. With the double limitation of the arc-shaped hole 3, the support frame 2 can be stably slid.

[0027] The bottom of the support frame 2 is connected to a rotating component 11 to drive the support frame 2 to move from one end of the arc-shaped hole 3 to the other end. During this process, the arc-shaped hole 3 is a quarter-circle arc segment. The rotating component 11 drives the support frame 2 to move from the left side of the cabinet chassis to the rear side of the cabinet chassis.

[0028] The detection assembly includes a sliding part 5, a flipping part 6, and a detection part. The sliding part 5 is mounted on the support frame 2, the flipping part 6 is slidably connected to the sliding part 5, and the detection part is mounted on the flipping part 6. The sliding part 5 is used to drive the flipping part 6 and the detection part to move left and right and up and down. The flipping part 6 drives the detection part to flip so that the detection end of the detection part is always aligned with the cabinet chassis, enabling the detection part to measure everything from height to length and width.

[0029] The L-shaped positioning block 4 abuts against one corner of the cabinet chassis for positioning, in order to cooperate with the sliding part 5, the flipping part 6, the detection part and the rotating part 11 to detect the dimensions of the cabinet chassis.

[0030] The specific detection process in this embodiment is as follows: First, the cabinet chassis is placed at the L-shaped positioning block 4, and initial data is measured. This initial data can be pre-designed during the production of the device. The initial data includes the lateral distance, longitudinal distance, and height between the detection unit and the L-shaped positioning block 4 at a specific position. The initial data also includes the distance between the detection unit and the side of the cabinet chassis that abuts against the L-shaped positioning block 4. Then, the detection unit is positioned at the location where the initial data was measured. This position is adjusted through the coordinated movement of the rotating part 11, the sliding part 5, and the flipping part 6 to obtain secondary data. The final size of the cabinet chassis is the corresponding initial distance minus the corresponding secondary data.

[0031] Furthermore, the inspection unit is equipped with a laser rangefinder 7, a high-precision instrument that uses a laser beam to measure the distance to a target. Its core function is to quickly and non-contactly acquire distance or dimensional parameters between objects. It is widely used in industrial inspection fields such as cabinet and chassis size measurement, engineering surveying, and automation control. It replaces traditional tools such as tape measures and calipers, enabling the quantitative inspection of the geometric parameters of objects.

[0032] Example 2, combined with Figure 1 and Figure 2 As shown, based on Embodiment 1, the difference between this embodiment and Embodiment 1 is that the sliding part 5 includes a crossbar 51, a first electric telescopic rod 52 and a second electric telescopic rod 53. The support frame 2 is provided with a vertical sliding groove. The crossbar 51 is slidably arranged in the vertical sliding groove. The first electric telescopic rod 52 is vertically arranged in the vertical sliding groove and its telescopic end is connected to the crossbar 51.

[0033] like Figure 7 As shown, a dovetail groove 13 is formed at the bottom of the crossbar 51 along its length. The second electric telescopic rod 53 at the bottom is arranged laterally inside the crossbar 51, and its telescopic end is connected to the flipping part 6. The flipping part 6 is slidably engaged with the dovetail groove 13. It can be seen that, on the one hand, the trapezoidal structure of the dovetail groove 13 can limit the horizontal displacement of the component, and the fitted inclined surface can prevent loosening and misalignment after connection. At the same time, it can guide the flipping part 6 to move along a fixed trajectory, ensuring the stability of the horizontal movement of the flipping part 6. On the other hand, after assembly, the component cannot be separated perpendicular to the groove direction, but can only slide along the length of the groove, thereby ensuring that the crossbar 51 can stably support the flipping part 6.

[0034] When measuring the height distance between the testing unit and the cabinet chassis, the first electric telescopic rod 52 and the second electric telescopic rod 53 are positioned at their maximum extension to ensure that the testing unit is located above the cabinet chassis when measuring the height of the secondary data and can measure the height distance between the testing unit and the cabinet chassis, thus completing the height measurement of the cabinet chassis.

[0035] When measuring the horizontal and vertical distances between the detection unit and the cabinet chassis, the first electric telescopic rod 52 and the second electric telescopic rod 53 are positioned at their minimum extension. At this time, the flipping unit 6 drives the detection unit to turn and align the detection end with the cabinet chassis. Meanwhile, there is a certain distance between the detection unit and the cabinet chassis, which facilitates the measurement of secondary data.

[0036] In this embodiment, the sliding part 5 facilitates the specific movement of the detection part for secondary data measurement, ensuring the normal operation of the detection part.

[0037] Example 3, combined with Figure 3 , Figure 4 and Figure 5 As shown, based on Embodiment 1, the flipping part 6 of this embodiment includes a support plate 61, a connecting rod 62 and a flipping plate 63. The support plate 61 is slidably engaged with the dovetail groove 13 and connected to the telescopic end of the second electric telescopic rod 53. In this embodiment, the support plate 61 serves as the supporting skeleton of the flipping part 6 to ensure the overall connection stability.

[0038] The connecting rod 62 is rotatably installed on the left end of the support plate 61. Specifically, the connecting rod 62 is L-shaped. In this embodiment, there are two connecting rods 62. The two connecting rods 62 are rotatably installed on the front and rear ends of the left side of the support plate 61. The two connecting rods 62 are respectively rotatably installed in the middle position of the front and rear ends of the flip plate 63.

[0039] The end of the flip plate 63 furthest from the connecting rod 62 is connected to a driving component 8 to drive it to flip. The flip plate 63 has a positioning groove for mounting the laser rangefinder 7. The laser rangefinder 7 is installed in the positioning groove to ensure a constant position. Specifically, when the driving component 8 is activated, one end of the flip plate 63 begins to move and achieves a 90-degree flip under the linkage and limiting action of the connecting rod 62.

[0040] In this process, the driving component 8 includes a lead screw 81, a limiting rod, a first sliding block 83, and a second sliding block 84. The lead screw 81 is laterally rotatably arranged on the support plate 61; the limiting rod is arranged parallel to the lead screw 81; the first sliding block 83 is threadedly connected to the lead screw 81 and rotatably connected to one side of the flip plate 63; the second sliding block 84 is slidably connected to the limiting rod and rotatably connected to the other side of the flip plate 63.

[0041] In this embodiment, the first sliding block 83 and the second sliding block 84 are located on the right side. The first sliding block 83 is rotatably mounted on the front right side of the flip plate 63, and the second sliding block 84 is rotatably mounted on the rear right side of the flip plate 63.

[0042] The specific working process is as follows: During the flipping process, the lead screw 81 rotates, causing the first sliding block 83 to move to the left. At this time, the first sliding block 83 pulls on the flipping plate 63, and the second sliding block 84 limits the flipping plate 63 and moves together with it under the action of the flipping plate 63. With the cooperation of the first sliding block 83 and the connecting rod 62, the flipping plate 63 rotates until it is perpendicular to the support plate 61. At this time, the position of the detection end of the laser rangefinder 7 changes, so that the laser rangefinder 7 can be aligned with the left side of the cabinet chassis to complete the measurement of the cabinet chassis length.

[0043] During reset, the lead screw 81 rotates in the opposite direction and drives the first sliding block 83 to move to the right. At this time, the first sliding block 83 pulls the flip plate 63, and the second sliding block 84 limits the flip plate 63 and moves together with it under the drive of the flip plate 63. With the cooperation of the first sliding block 83 and the connecting rod 62, the flip plate 63 rotates until the flip plate 63 is arranged parallel to the support plate 61 to reset.

[0044] Furthermore, the lead screw 81 is connected to a first motor 9. Specifically, the first motor 9 is located at the middle left side of the support plate 61 and is fixedly mounted on the support plate 61 by a mounting bracket, offset from the position of the connecting rod 62. The output end of the first motor 9 is connected to a first gear, and one end of the lead screw 81 is fitted with a second gear. The first gear and the second gear are connected by a transmission chain, so that the first motor 9 can transmit power to the lead screw 81 and drive the lead screw 81 to rotate.

[0045] Example 4, based on Example 1, the base 1 has a receiving cavity 10 communicating with the arc-shaped hole 3. The rotating component 11 in this example includes a connecting rod 111 and a rotating shaft 112, wherein one end of the connecting rod 111 is fixedly connected to the support frame 2; the rotating shaft 112 is vertically rotatably installed in the receiving cavity 10 and is fixedly connected to the other end of the connecting rod 111.

[0046] Specifically, the rotating shaft 112 is located at the center of the arc-shaped hole 3 (a quarter-circle arc segment). When the rotating shaft 112 rotates, the connecting rod 111 drives the slider at the bottom of the support frame 2 to move along the trajectory of the arc-shaped hole 3 to the other end of the arc segment, completing the alignment of the laser rangefinder 7 with the rear side of the cabinet chassis, ensuring the measurement of the width of the cabinet chassis.

[0047] Furthermore, a second motor 12 is connected to one end of the rotating shaft 112. Specifically, the second motor 12 provides power for the rotation of the rotating shaft 112. In addition, the second motor 12 is located inside the accommodating cavity 10. It can be seen that the base 1 is equipped with a heat dissipation component for the second motor 12 to ensure its normal operation. In addition, a cavity door corresponding to the position of the second motor 12 is opened on the front side of the base 1 for easy maintenance.

[0048] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
