[0029] like Figure 1 and 2As shown, in one embodiment of the present utility model, the automobile parts detection device includes a frame 100, a positioning mechanism 200 and an inner diameter measuring mechanism 300; the positioning mechanism 200 and the inner diameter measuring mechanism 300 are relatively arranged on the frame 100; and the positioning mechanism 200 is used to be positioned and connected with one end of the automobile tubular accessory; the inner diameter measuring mechanism 300 includes a measuring spindle 310, a measuring movable shaft 320 and a pressure sensor 330; one side end of the measuring spindle 310 is used to extend to the internal setting of the other end of the automobile tubular accessory; one end of the measuring movable shaft 320 is telescopically connected to the placement cavity 311 inside the measuring spindle 310; the other end of the measuring movable shaft 320 is used to abut against the inner wall of the automobile tubular accessory; the pressure sensor 330 is connected to the measuring movable shaft 320 and is used to abut against the inner wall of the automobile tubular accessory.
[0030] The technical solution of the present invention positions and fixes one side of an automobile tubular fitting through a positioning mechanism, combines a measuring spindle with a measuring movable shaft and a pressure sensor, and because the diameter of the measuring spindle itself is known, it is possible to judge whether the measuring movable shaft just contacts its inner wall based on the abutment stress of the pressure sensor; if the shear pressure after contact is 0 or close to 0, the inner diameter of the automobile tubular fitting can be measured based on the sum of the extended length of the measuring movable shaft and the diameter of the measuring spindle itself; thereby achieving accurate measurement of the inner diameter of the automobile tubular fitting within a small error or within an allowable range, thereby improving detection efficiency.
[0031] In some embodiments, there are at least two measuring movable axes 320, which are symmetrically arranged around the measuring main axis 310. Figure 1 and 2 As shown, there are four measuring movable axes 320, and two of them form a pair. That is, by combining the two sets of measurement data, the final measured value can be further known, thereby improving the accuracy of the data.
[0032] Specifically, in some embodiments, Figure 1 As shown, the inner diameter measuring mechanism 300 also includes a measuring transverse movement component 340 and a motion drive component 350; the fixed end of the measuring transverse movement component 340 is connected to the frame 100; the movable end of the measuring transverse movement component 340 is connected to the measuring spindle 310, so that the measuring spindle 310 moves transversely toward or away from the positioning mechanism 200; the motion drive component 350 is connected to the measuring transverse movement component 340; and the movable end of the motion drive component 350 is connected to the measuring movable shaft 320, so that the measuring movable shaft 320 moves up and down toward or away from the measuring spindle 310.
[0033] Specifically, in some embodiments, Figure 2 As shown, the measuring transverse movement assembly 340 includes a second transverse movement driving component 341 and a support 342; the second transverse movement driving component 341 is fixedly connected to the frame 100 and connected to the support 342; the support 342 is movably connected to the frame 100; and the mounting end of the motion driving assembly 350 is connected to the support 342; one end of the measuring spindle 310 is fixedly connected to the support 342. Figure 2 As shown, a guide slider 344 is provided at the bottom of the support 342; a guide rail 345 is provided on the frame 100; and the guide slider 344 is movably connected to the guide rail 345. Furthermore, the second transverse driving component 341 is a second transverse driving cylinder or a second transverse driving screw.
[0034] Specifically, in some embodiments, Figure 2 and 3 As shown, the motion drive assembly 350 includes a push rod 351 and a third transverse driving component 352; the third transverse driving component 352 is connected to the support 342 and connected to one end of the push rod 351; the other end of the push rod 351 passes through the placement cavity 311 and abuts against the measurement movable shaft 320. Figure 3 As shown, the other end of the pushing rod 351 is provided with a pushing slope 353; the bottom of the measuring movable shaft 320 abuts against the pushing slope 353. Furthermore, the pushing slope 353 is in the shape of a conical slope with an isosceles triangle cross section. That is to say, in the process of pushing the pushing rod 351 to the inner depth of the placement cavity 311, due to the setting of the pushing slope 353, the measuring movable shaft 320 is pushed upward and contacts the inner wall of the automobile tubular fitting; when the shear pressure after contact is 0 or close to 0, the inner diameter of the automobile tubular fitting can be measured based on the sum of the extended length of the measuring movable shaft and the diameter of the measuring spindle itself; thereby achieving accurate measurement of the inner diameter of the automobile tubular fitting within a small error or within an allowable range, thereby improving detection efficiency. Among them, Figure 2 As shown, a mounting groove 343 is provided in the support 342, and the third transverse driving component 352 is installed inside the mounting groove 343. Furthermore, the third transverse driving component 352 is a third transverse driving screw rod or a third transverse driving cylinder.
[0035] Specifically, in some embodiments, Figure 1As shown, the positioning mechanism 200 includes a first transverse driving component 210, a support component 220, and an elastic limiting component 230; the first transverse driving component 210 is connected to the frame 100 and is connected to one end of the elastic limiting component 230; the outer surface of the elastic limiting component 230 is used to connect to the inner wall of the automobile tubular accessory; the support component 220 is connected to the frame 100 and is arranged below the elastic limiting component 230; and the support component 220 is used to abut the outer surface of the automobile tubular accessory. In other words, the bottom support and positioning of the automobile tubular accessory by the support component 220, combined with the internal elastic limiting effect of the automobile tubular accessory by the upper elastic limiting component, can improve the assembly stability of the automobile tubular accessory and avoid sliding or rotation that affects measurement accuracy. Among them, the first transverse driving component 210 can be a first transverse driving cylinder or a first transverse driving screw.
[0036] Specifically, in some embodiments, Figure 2 As shown, the support component 220 is provided with an arc-shaped support cavity 221; the interior of the support cavity 221 is used for abutting the outer surface of the automobile tubular fitting. Figure 2 As shown, a limiting groove 222 is further provided at the bottom of the support cavity 221. This structure prevents the automobile tubular fitting from moving in the circumferential direction or toward the inner diameter measuring mechanism 300 through the initial limiting effect of the support cavity 221 and the secondary limiting effect of the limiting groove 222, thereby improving the assembly stability of the automobile tubular fitting.
[0037] Specifically, in some embodiments, Figure 1 and 2 As shown, the elastic limiting component 230 includes a support rod 231 and an elastic connecting member 232; one end of the support rod 231 is connected to the movable end of the first transverse driving component 210; the elastic connecting member 232 is connected around the outer surface of the support rod 231. Figure 2 and 4 As shown, the elastic connector 232 includes at least one spring 234 and an arc-shaped stop plate 233. The springs 234 are arranged in an array and arranged in parallel on the outer surface of the support rod 231. The stop plate 233 is connected to one end of the spring 234 away from the support rod 231. In other words, the elastic compression of the spring and the abutment of the arc-shaped stop plate 233 further enhance the positioning stability of the automotive tubular accessory.
[0038] Specifically, in some embodiments, Figure 4As shown, the side of the limiting plate 233 facing the inner diameter measuring mechanism 300 is provided with a guide arc surface 235. The guide arc surface 235 is a semicircular arc surface. This structure can improve the smoothness of the limiting plate 233 in guiding the insertion of the automobile tubular fitting, reducing collision damage between the two.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
