[0023] It should also be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0024] Please refer to the attached Figures 1 to 5The present application provides a laser measuring instrument for the size of automobile parts, including an inspection platform 1, on which a first stopper 2, a second stopper 3, a sliding platform 4, a white laser lamp 5, a prism 6, a light shielding plate 7 and a display panel 8 are arranged. The first stopper 2 is fixed on the inspection platform, the second stopper 3 and the sliding platform 4 are both slidably connected to the inspection platform, the second stopper 3 is provided with the light shielding plate 7, the light shielding plate 7 is provided with a light-transmitting slit 9, the inspection platform is provided with the white laser lamp 5 and the prism 6, the light emitted by the white laser lamp 5 passes through the prism 6 and the light-transmitting slit 9 and then irradiates the display panel 8, and displays a colored strip-shaped bright spot. When testing, the parts are placed on the inspection platform, the left end of the standard parts contacts the first stopper 2, and the second stopper 3 is slid to contact the right end of the standard parts. Then the sliding platform 4 is adjusted to allow the light emitted by the white laser lamp 5 to pass through the prism 6 and the light-transmitting slit 9 and then irradiate the display panel 8. When the white laser light 5 passes through the prism 6, it is dispersed, and the white light is decomposed into seven color bands of red, orange, yellow, green, blue, indigo, and purple. The light shielding plate blocks the light, and allows the light of a certain area to pass through the light-transmitting slit 9, and the light passing through presents a certain color on the display board 8. Preferably, when placing standard parts, the sliding table 4 is adjusted to allow the yellow or green color dispersed by the white laser light 5 to pass through the light-transmitting slit 9 and be projected on the display board 8, and the display board 8 is now yellow or green.

[0025] After adjusting the position, take out the standard parts from the test bench, and then put the parts to be sampled and tested on the test bench, and similarly make the parts to be sampled and tested contact with the first stopper 2, slide the second stopper 3 to make it contact with the right end of the parts to be sampled and tested, and observe the color and position of the display on the display board 8. When the displayed position and color move to the front of the spectrum, it means that the size of the parts to be sampled and tested is too small, and when the displayed position and color move to the rear of the spectrum, it means that the size of the parts to be sampled and tested is too large. When the present invention detects the size of automobile parts, it only needs to place the parts against the first baffle plate, and then place the second baffle plate against the parts, and the tolerance of the parts can be judged on the display board 8. The seven color bands of red, orange, yellow, green, blue, indigo and purple are continuous. When testing, the colors presented on the display board 8 are different under different error conditions. The test personnel can judge the error more quickly and improve the efficiency of the test.

[0026] Specifically, the display board 8 is a whiteboard, and a scale 24 is provided on the display board 8. The staff further judges the error amount according to the position of the strip bright spot. For example, when placing the standard parts, the strip bright spot is located at the position of scale 240. If the strip bright spot is located at the position of scale 24-1 when placing the sample inspection parts, the size of the sample inspection parts is too small. If the strip bright spot is located at the position of scale 241 when placing the sample inspection parts, the size of the sample inspection parts is too large. Preferably, several parts with different error values ​​are tested, and the scale 24 is drawn by the strip bright spot formed on the display board 8 during the test, and the error value can be judged according to the scale 24. The error situation is judged according to the combination of the position and color of the strip bright spot. The color change is more eye-catching, which can improve the efficiency of detection. The combination of color change and scale 24 can make the measurement more accurate.

[0027] Specifically, the white laser light 5 includes a red laser light 21, a green laser light 22, and a blue laser light 23, which are irradiated at different positions of the prism 6, and the red laser light 21, the green laser light 22, and the blue laser light 23 are collected on the display board 8 after passing through the prism 6 to form a seven-color color band with uniform color band width. The red laser light 21, the green laser light 22, and the blue laser light 23 include the three primary colors of light and can combine to produce white light. Different light rays have different refractive indices in the prism 6, and the three colors of light rays are refracted by the prism 6 and irradiated on the display board 8. The three laser lights emit light rays at certain angles from different positions, and the light rays are collected on the display board 8 after passing through the prism 6, thereby forming a seven-color color band with uniform color band width. By designing the angles of the three laser lights, the three colors of laser lights can be used for color adjustment, so that the width of the dispersed color band is uniform, which is convenient for staff to observe.

[0028] Preferably, the sliding table 4 is provided with a column 10, and the column 10 is provided with two adjusting components 11. The adjusting component 11 includes a swing arm 12, a first screw 13, a second screw 14 and a threaded cylinder 15. The swing arm 12 is rotatably connected to the column 10. The upper end of the first screw 13 is hinged to the swing arm 12. The lower end of the second screw 14 is hinged to the column 10. The threaded cylinder 15 is threadedly connected to the first screw 13 and the second screw 14. The red laser lamp 21 and the blue laser lamp are installed on the swing arm 12, and the green laser lamp 22 is installed on the column 10. An expansion link with adjustable length is formed by the first screw 13, the second screw 14 and the sleeve. By rotating the threaded cylinder 15, the depths of the first screw 13 and the second screw 14 in the threaded cylinder 15 are adjusted, so as to change the length of the expansion link, thereby driving the swing arm 12 to rotate, and adjusting the angles of the red laser lamp 21, the green laser lamp 22 and the blue laser lamp 23, so that the three kinds of light converge on the display board 8 after passing through the triangular prism 6. Compared with the color band formed by directly adopting a single white laser lamp 5, the distribution widths of various colors in the color band of the present invention are more uniform. Due to the uniform width distribution of the color band, when the staff conducts inspections, the deviation of the parts is more intuitive.

[0029] Preferably, the pitch of the first screw 13 is different from the pitch of the second screw 14, and the thread rotation directions of the first screw 13 and the second screw 14 are the same. When the threaded sleeve rotates one week, the telescopic length of the expansion link is equal to the pitch difference between the first screw 13 and the second screw 14, which improves the adjustment accuracy of the expansion link and can adjust the gas color band more precisely, making the adjusted color band easier to observe. For example, when the threaded sleeve is rotated one week, the first screw 13 extends out of the threaded sleeve by a length of one pitch, and at the same time, the second screw 14 enters the screw sleeve by a length of one pitch. The difference between the two is the actual change length of the expansion link, which can more precisely control the adjustment of the gas color band.

[0030] Specifically, the light blocking plate 7 is vertically arranged on the second baffle, the light transmitting slit 9 is vertically arranged on the light blocking plate 7, the cross section of the light transmitting slit 9 is V-shaped, and the end with a larger width in the cross section faces the display board 8. The V-shaped structure can reduce the blocking of light, and the light passing through the light projecting slit can all irradiate on the display board 8, forming a strip-shaped bright spot with clear boundaries, which is convenient to observe on the display board 8.

[0031] Specifically, the inspection table 1 is provided with a first slide rail 16, and the second baffle is slidably connected to the first slide rail 16. The second baffle reciprocates along the first slide, which can ensure that the second baffle moves to a predetermined position and improve the stability.

[0032] Specifically, the detection platform is provided with a second slide rail 17, the sliding platform 4 is slidably connected to the second slide rail 17, the sliding platform 4 is provided with a threaded through hole 18, and the threaded hole is provided with a locking bolt 19. The sliding platform 4 is moved to a proper position, and then the locking bolt 19 is tightened to fix the sliding platform 4 on the detection platform.

[0033] Specifically, an operating knob 20 is provided on the top of the locking bolt 19. The locking bolt 19 is rotated by operating the knob 20, which is convenient to operate.

[0034] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. The protection scope of the present invention should be based on the protection scope of the claims.
