[0041] See also Figure 1-Figure 10 The present invention provides a technical solution: an automobile gap detection device, comprising a base 1, a support frame 2 is installed on the top of the base 1 through a rotating seat 9, a limit mechanism 3 is installed in the support frame 2, driving mechanisms 6 are provided on both sides of the support frame 2, a transmission rod 5 is provided on the inner side of the driving mechanism 6, and a support rod 7 is connected between adjacent ends of the transmission rod 5, an adjustment mechanism 4 is installed on one side of the support rod 7, and laser test elements 8 are installed on the adjustment mechanisms 4 on both sides, and the gap between parts in the limit mechanism 3 is detected by the laser of the laser test elements 8 on both sides;

[0042] The adjustment mechanism 4 includes an adjustment seat 401, and one side of the adjustment seat 401 is connected with multiple sliders 403 equidistantly along the axis, and the laser test element 8 is installed on one side of the slider 403. The slider 403 is configured to move linearly along the radial direction of the adjustment seat 401, and the measurement range of the multiple laser test elements 8 is adjusted by radial movement of the multiple sliders 403.

[0043] A plurality of travel grooves 404 are equidistantly provided along the axis on one side of the adjustment seat 401, the slider 403 is slidably connected in the travel groove 404, the inner side of the slider 403 is connected to the outer wall of the laser test element 8, a slide rod 405 is connected to the side of the slider 403 away from the laser test element 8, the slide rod 405 is slidably connected in the slide hole provided in the inner cavity of the travel groove 404, and the other end of the slide rod 405 is connected to a step block, the outer side wall of the slide rod 405 is sleeved with a spring 406, and the two ends of the spring 406 are respectively connected to the step block and one side of the outer side of the adjustment seat 401;

[0044] The slider 403 is connected to a hinge block 407 on one side, a connecting rod 408 is hinged on the bottom of the hinge block 407, and a rotating disk 409 is hinged between the multiple connecting rods 408.

The connecting block 413 is connected to the outside of the support rod 7 at the corresponding position. The laser testing element 8 includes protective shells respectively arranged on the sliders 403 on both sides, and laser displacement sensors and induction cameras are respectively installed in the protective shells on both sides.

[0045] Specifically: when performing gap detection, the cylinder liner or cylinder head to be tested can be clamped in the limit mechanism 3, and the position of the laser test element 8 can be adjusted so that the laser displacement sensor passes the test laser from the side wall of the cylinder liner, and the sensing camera on the corresponding side acquires the laser data.

[0047] See also Figure 3-Figure 4The driving mechanism 6 includes a driving turntable 601, which is connected to one side of the transmission rod 5 at the corresponding position through a shaft body. The driving turntable 601 is rotated to drive the transmission rod 5 to adjust the tilt angle, and a lifting plate 606 is rotatably connected outside the shaft body, and a lifting block 607 is connected between the lifting plates 606 on both sides through a rod body, and a lifting hydraulic cylinder 608 is connected to the bottom of the lifting block 607, and the lifting hydraulic cylinder 608 is connected to the top of the supporting bracket 2.

[0048] Specifically, through the designed driving mechanism 6, when the part hole is a tilting device on the part surface, the electric push rod 604 can be extended to drive the fixed block 603 to move, and the movement of the fixed block 603 can drive the driving rod 602 to move. The other end of the driving rod 602 can push the driving turntable 601 to rotate, and the driving turntable 601 can drive the inner transmission rod 5 to rotate through the shaft body. The rotation of the transmission rod 5 can drive the adjustment mechanism 4 connected on both sides to rotate synchronously around the limit mechanism 3, so that the relative axis between the laser test element 8 and the gap hole can be adjusted, which is conducive to satisfying the adjustment adaptation of the punching angle on the part surface after the axis direction is adjusted;

[0049] See also Figure 2-Figure 3 The limiting mechanism 3 includes a limiting ring 301, and the limiting ring 301 is connected with a mounting plate 302 on all sides. The bottom side of the mounting plate 302 is connected to a limiting hydraulic cylinder 303, and one end of the piston rod of the limiting hydraulic cylinder 303 is inserted into an opening on one side of the limiting ring 301, and one end of the piston rod of the limiting hydraulic cylinder 303 is connected to a limiting block 304, and the cross-sectional shape of the limiting block 304 is an arc.

[0052] Specifically, through the designed limiting mechanism 3, when inspection is required, the part can be placed in the limiting ring 301, and in order to improve the measurement accuracy, the gap to be inspected needs to be placed between the corresponding adjustment mechanisms 4 on both sides, and when the axial hole corresponds to the central axis of the laser test element 8, the arc limiting block 304 is fully clamped and limited by the corresponding side limiting hydraulic cylinder 303. The limiting hydraulic cylinder 303 set on the four axes solves the problem of inconvenient clamping and limiting of the special-shaped surfaces of different parts, which is beneficial to improving the centering detection stability of the hole gap to be inspected.

[0053] Working principle: When in use, when performing gap detection, the cylinder liner or cylinder head to be detected is clamped in the limiting mechanism 3, and the position of the laser test element 8 is adjusted so that the laser displacement sensor passes the test laser through the side wall of the cylinder liner. The sensing camera on the corresponding side acquires the laser data. When the laser is offset or blocked by the gap, the sensing camera obtains the current test deviation data. When the inner diameter of the cylinder liner of the component to be tested changes, the output shaft of the driving motor of the rotating driving member 410 drives the matching gear assembly and the rotating disk 409 to rotate. The rotating disk 409 rotates to pull the connecting rod 408 and the hinge block 407 to move. The movement of the hinge block 407 drives the laser test element 8 and the slider 403 to move. The movement of the slider 403 pulls the slide rod 405 to slide in the slide hole, and the distance between the laser test element 8 and the axis position of the adjustment seat 401 is adjusted.

[0054] When the part hole is a tilting device on the part surface, the electric push rod 604 is extended to drive the fixed block 603 to move, and the fixed block 603 moves to drive the driving rod 602 to move. The other end of the driving rod 602 pushes the driving turntable 601 to rotate, and the driving turntable 601 drives the inner transmission rod 5 to rotate through the shaft body. The rotation of the transmission rod 5 drives the adjustment mechanism 4 connected on both sides to rotate synchronously around the limit mechanism 3, so as to adjust the relative axis between the laser test element 8 and the gap hole to match the part surface angle;

[0055] When testing is required, the part is placed in the limit ring 301. To improve the measurement accuracy, the gap to be tested needs to be placed between the corresponding adjustment mechanisms 4 on both sides. When the axial hole corresponds to the central axis of the laser test element 8, the arc limit block 304 is fully clamped and limited by the corresponding side limit hydraulic cylinder 303.
