Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0037] like Figures 1 to 5 As shown, according to some embodiments of the present application, a height testing machine includes:

[0038] Working frame 100;

[0039] The height measuring mechanism 300 is disposed on the top of the work frame 100 and is used to detect the height of the automobile part 180;

[0040] The clamping mechanism 200 is disposed on the top of the work frame 100 and is used to clamp the automobile part 180. The clamping mechanism 200 includes a first clamping seat 210, a second clamping seat 222, a first clamping block 211, and a second clamping block 223. The first clamping seat 210 is disposed on the top of the work frame 100, and the second clamping seat 222 is slidably disposed on the top of the work frame 100. The first clamping block 211 is disposed on one side of the first clamping seat 210, and the second clamping block 223 is disposed on one side of the second clamping seat 222. The first clamping block 211 and the second clamping block 223 are slidably disposed on the top of the work frame 100. The two clamping blocks 223 are separated to form a clamping gap 215. A first clamping surface 214 is provided on one side of the first clamping block 211, and the first clamping surface 214 faces the clamping gap 215. There are two second clamping blocks 223, and a second clamping surface 225 is provided on one side of the second clamping block 223. The second clamping surfaces 225 of the two second clamping blocks 223 are separated to form a limiting gap 224. The limiting gap 224 is connected to the clamping gap 215. The first clamping surface 214 and the second clamping surface 225 are respectively used to contact with the two sides of the automobile part 180.

[0041] It can be understood that before the automobile part 180 is measured in height, the automobile part 180 is placed in the clamping interval 215, and the second clamping seat 222 is slid. The second clamping seat 222 drives the second clamping block 223 to move, so that the second clamping surfaces 225 of the two second clamping blocks 223 are in contact with one side of the automobile part 180, and one side of the tested automobile part 180 is located in the limit interval 224, and the first clamping surface 214 of the first clamping block 211 is in contact with the other side of the automobile part 180, thereby increasing the clamping area of ​​the first clamping block 211 and the second clamping block 223 on the automobile part 180, avoiding slight displacement of the automobile part 180 when the height measuring mechanism 300 and the automobile part 180 are measured in height, thereby improving the height accuracy of the automobile part 180 detection.

[0042] like Figures 1 to 3 As shown, according to some embodiments of the present application, the clamping mechanism 200 includes an extended clamping block 212, which is disposed on one side of the first clamping block 211. One side of the extended clamping block 212 is provided with an extended clamping surface 213, which faces the clamping interval 215, and is used to contact the outer edge of the automotive part 180.

[0043] It is understandable that when the first clamping surface 214 of the first clamping block 211 contacts the other side of the automobile part 180, the extended clamping surface 213 of the extended clamping block 212 contacts the outer edge of the automobile part 180, thereby further improving the stability of the clamping of the automobile part 180.

[0044] like Figures 1 to 5As shown, according to some embodiments of the present application, the clamping mechanism 200 includes a clamping base 220 and a clamping movable device 221. The clamping base 220 is installed on the top of the workbench 100, the clamping movable device 221 is installed on the top of the clamping base 220, the second clamping seat 222 is connected to the clamping movable device 221, and the clamping movable device 221 drives the second clamping seat 222 to move.

[0045] It is understandable that when the clamping moving device 221 is started, the clamping moving device 221 drives the second clamping seat 222 to move, and the second clamping seat 222 drives the two second clamping blocks 223 to move, thereby facilitating the second clamping surfaces 225 of the two second clamping blocks 223 to contact one side of the automotive part 180.

[0046] like Figures 1 to 3 As shown, according to some embodiments of the present application, a placement jig 160 is provided on the top of the workbench 100, and the placement jig 160 is located below the clamping interval 215. An air avoidance groove 170 is opened on the top of the placement jig 160, and the air avoidance groove 170 extends along the height direction of the placement jig 160.

[0047] It can be understood that when the automobile part 180 needs to be clamped, the automobile part 180 is placed above the placement jig 160, so that the first clamping surface 214 of the first clamping block 211 and the second clamping surface 225 of the second clamping block 223 can face the two sides of the automobile part 180, thereby facilitating the clamping of the automobile part 180; when the bottom of the automobile part 180 is designed with a protrusion, the protrusion can be inserted into the air avoidance groove 170 of the placement jig 160, so that the automobile part 180 can be placed squarely on the placement jig 160.

[0048] like Figures 1 to 7 As shown, according to some embodiments of the present application, the height measuring mechanism 300 includes a height measuring frame 310, a lifting device 350, a lifting seat 322, a detection seat 330, a height measuring sensor 331 and a height measuring probe 332. The height measuring frame 310 is arranged on the top of the working frame 100, the lifting device 350 is arranged on one side of the height measuring frame 310, the lifting seat 322 is arranged on one side of the lifting device 350, the lifting device 350 drives the lifting seat 322 to rise and fall, the detection seat 330 is arranged on one side of the lifting seat 322, the height measuring sensor 331 is arranged on the top of the detection seat 330, the height measuring probe 332 is arranged on the bottom of the detection seat 330, and the height measuring sensor 331 is connected to the height measuring probe 332 by signal.

[0049] It is understandable that when the height of the automobile part 180 is measured, the lifting device 350 is started, and the lifting device 350 drives the lifting seat 322 to descend, so that the lifting seat 322 drives the height measuring probe 332 to contact the top of the automobile part 180, thereby facilitating the height measuring sensor 331 to collect the height information of the automobile part 180.

[0050] In addition, there may be a plurality of height measuring probes 332 , so that the plurality of height measuring probes 332 can respectively contact different surfaces of the top of the automobile part 180 , thereby facilitating detection of whether the top of the automobile part 180 is flat.

[0051] like Figure 6 to Figure 7 As shown, according to some embodiments of the present application, the lifting device 350 includes a lifting frame 311, a lifting screw rod 312, and a lifting nut 313. The lifting frame 311 is arranged on one side of the height measuring frame 310. The lifting screw rod 312 is rotatably connected to the inside of the lifting frame 311. The lifting nut 313 is sleeved on the outside of the lifting screw rod 312. The lifting seat 322 is installed on one side of the lifting nut 313.

[0052] It is understandable that when the lifting screw 312 rotates, the lifting screw 312 drives the lifting nut 313 to move, and the lifting nut 313 drives the lifting seat 322 to move, thereby driving the height measuring probe 332 to contact the top of the automobile part 180.

[0053] like Figure 6 to Figure 7 As shown, according to some embodiments of the present application, the lifting device 350 includes a fixed seat 315, a movable shaft 343, a rotating turntable 314, a first half ring 340 and a second half ring 341. The fixed seat 315 is arranged at the top of the lifting frame 311, the movable shaft 343 is arranged at the top of the fixed seat 315, the movable shaft 343 is coaxially transmitted with the lifting screw 312, the rotating turntable 314 is arranged at the top of the movable shaft 343, the rotating turntable 314 is coaxially transmitted with the movable shaft 343, the first half ring 340 and the second half ring 341 are arranged at the top of the fixed seat 315, the first half ring 340 and the second half ring 341 are elastic, the first half ring 340 and the second half ring 341 are separated to form a fixed interval 342, and one end of the movable shaft 343 is located inside the fixed interval 342.

[0054] It can be understood that when the lifting seat 322 drives the height measuring probe 332 to contact the top of the automobile part 180, the first half ring 340 and the second half ring 341 approach each other, so that the two sides of the fixed interval 342 contact the movable rotating shaft 343, thereby facilitating the fixing of the position of the transmission screw after rotation.

[0055] like Figure 6 As shown, according to some embodiments of the present application, one end of the first half ring 340 is separated from one end of the second half ring 341 to form a movable gap 317, and the movable gap 317 is connected to the fixed gap 342. A fixing hole 318 is opened on one side of the first half ring 340, and the fixing hole 318 is connected to the movable gap 317. The fixing hole 318 passes through one end of the second half ring 341, and a fixing bolt 319 is connected to the inner thread of the fixing hole 318.

[0056] It is understandable that when the lifting seat 322 drives the height measuring probe 332 to contact the top of the automobile part 180, the fixing bolt 319 is screwed into the fixing hole 318, so that the first half ring 340 and the second half ring 341 are close to each other, thereby facilitating the fixing of the position of the lifting screw rod 312 after rotation.

[0057] like Figure 1 to Figure 2 As shown, according to some embodiments of the present application, a first placement rack 110 is provided on the top of the workbench 100 , and a plurality of first placement slots 120 are opened on the top of the first placement rack 110 , and height measuring standard blocks 130 of different heights are placed in the plurality of first placement slots 120 .

[0058] It can be understood that before measuring the height of the automobile part 180, in order to ensure the accuracy of the detection value of the height measuring mechanism 300, it is necessary to place the height measuring standard block 130 of the first placement rack 110 on the placement fixture 160 (the height of the height measuring standard block 130 is consistent with the standard height of the automobile part 180 to be tested), and the height measuring mechanism 300 detects the height of the height measuring standard block 130. When the detected height is equal to the height of the height measuring standard block 130, the height measuring standard block 130 is taken out, and then the automobile part 180 is placed on the placement fixture 160 for testing. During the test, the height of the product can be screened by software in the prior art, thereby facilitating improving the accuracy of the detection.

[0059] like Figure 1 to Figure 2 As shown, according to some embodiments of the present application, a second placement rack 140 is provided on the top of the workbench 100 , and a plurality of second placement slots 150 are opened on the top of the second placement rack 140 , and the second placement slots 150 are used to place the automobile parts 180 to be tested.

[0060] It is understandable that when the height measuring mechanism 300 is being calibrated, the automobile part 180 can be temporarily stored in the second placement slot 150 of the second placement rack 140 .

[0061] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
