For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The utility model provides a laser distance measuring and positioning ruler for top surface arrangement of spare parts, which adopts an adjustable ruler component and a laser distance meter to work together for positioning, effectively reducing the complexity of positioning the installation holes of the motor vehicle assembly spare parts, making the operation safer, improving the positioning accuracy, and greatly improving the quality and efficiency of the measurement process.

[0039] like Figure 1 and Figure 2 The laser distance measuring and positioning ruler of the utility model comprises a rotating base 1, an adjustable ruler assembly 2, a support frame 3 and a laser distance meter 4. The laser distance meter 4 is arranged on the top of the adjustable ruler assembly 2, and the adjustable ruler assembly 2 is horizontally mounted to the top of the support frame 3 through the rotating base 1. The adjustable ruler assembly 2 rotates in a vertical plane under the action of the rotating base 1. The laser distance meter 4 emits a laser, which is projected upward onto the top surface of the motor vehicle compartment, thereby locating the drilling position required for the installation of spare parts onto the top surface of the motor vehicle compartment, playing a role of projection positioning. At the same time, when multiple laser distance meters 4 are set, the posture of the utility model can be calibrated by comparing the degrees between the multiple laser distance meters 4.

[0040] like Figure 1 The support frame 3 includes a column 31 and a diagonal brace 32 . The column 31 is vertically arranged, and the diagonal brace 32 is diagonally arranged. The top of the diagonal brace 32 is connected to the outer wall of the column 31 to effectively support the column 31 . Figure 1 In the embodiment of the present invention, three diagonal braces 32 are provided, which are evenly arranged on the periphery of the column 31. Specifically, a hoop 33 is provided around the periphery of the column 31, and a connecting plate 34 is provided on the outer wall of the hoop 33. A double-ear plate 36 is provided on the top of the diagonal brace 32, and the connecting plate 34 is inserted into the double-ear plate 36 and connected to each other by inserting a transverse hinge shaft 35. The inclination angle of the diagonal brace 32 can be changed based on the hinge shaft 35.

[0041] The hoop 33 is sleeved on the outer circumference of the column 31 and can be stabilized at a certain height of the column 31 by friction. In other embodiments, the hoop 33 can also be installed on the column 31 by threaded connection, the hoop 33 is provided with an internal thread, and the outer wall of the column 31 is provided with an external thread. The height of the hoop 33 is adjusted by rotating the hoop 33, thereby adjusting the height of the connection point between the diagonal brace 32 and the column 31.

[0042] During assembly, the hoop 33 is looped around the outer periphery of the column 31 and stabilized at a certain height, and the angle of the diagonal brace 32 is adjusted so that the bottom end of the diagonal brace 32 is in the same plane as the bottom end of the column 31, or the bottom end of the column 31 is higher than the bottom end of the diagonal brace 32 and the bottom end of the diagonal brace 32 is in the same plane.

[0043] like Figure 1 and Figure 2 The rotating base 1 includes a U-shaped slot 11, a rotating plate 12, a ruler sleeve 14 and a bolt 15. The bottom of the U-shaped slot 11 is fixed to the top of the column 31, and the notch of the U-shaped slot 11 faces upward. The rotating plate 12 is vertically inserted into the notch of the U-shaped slot 11 and connected to each other by inserting a horizontal bolt 15. A tightening handle 13 is provided at one end of the bolt 15 on the U-shaped slot 11. The ruler sleeve 14 is connected to the top of the rotating plate 12 and is provided with a horizontal through hole for inserting a ruler 21.

[0044] The ruler sleeve 14 and the rotating plate 12 can be an integrally formed structure. The rotating plate 12 is circular. When the rotating plate 12 rotates in the notch of the U-shaped slot 11 , the edge of the rotating plate 12 will not rub against the inner wall of the U-shaped slot 11 .

[0045] During assembly, the rotating plate 12 is inserted into the notch of the U-shaped slot 11 and is clamped and fixed by the bolt 15 and the tightening handle 13. When the angle needs to be adjusted, the bolt 15 is loosened by the tightening handle 13, and the U-shaped slot 11 no longer tightly clamps the rotating plate 12. The rotating plate 12 can rotate around the bolt 15 in the notch of the U-shaped slot 11, thereby changing the through-hole direction of the ruler sleeve 14.

[0046] like Figure 1 The adjustable ruler assembly 2 includes a ruler 21 and a laser rangefinder base 22. The ruler 21 is laterally inserted into the through hole of the ruler sleeve 14. A transverse ruler insertion hole 23 is provided at the lower part of the laser rangefinder base 22, and the ruler 21 is laterally inserted into the ruler insertion hole 23. The laser rangefinder 4 is located at the upper part of the laser rangefinder base 22.

[0047] The cross section of the ruler 21 is circular, and accordingly, the through hole of the ruler sleeve 14 and the ruler insertion hole 23 are also circular. Therefore, the ruler 21 can rotate in the through hole of the ruler sleeve 14, and the laser rangefinder base 22 can also rotate outside the ruler 21.

[0048] There are two laser rangefinders 4, and correspondingly, there are two laser rangefinder bases 22. A scale 24 is provided on the ruler 21, in which one laser rangefinder base 22 and the laser rangefinder 4 are located at the 0 scale position, as a reference, and the other laser rangefinder base 22 and the laser rangefinder 4 move laterally on the ruler 21. The laser rangefinder 4 and the laser rangefinder 2 can adopt YHJ-100J and the like. Of course, the utility model can include more laser rangefinders 4 and be equipped with corresponding laser rangefinder bases 22, which can generate multiple positioning points and realize multi-hole simultaneous positioning. When all laser rangefinders 4 are turned on, the laser can be projected onto the top surface of the motor vehicle compartment. At the same time, the laser rangefinder 4 can also measure the distance between it and the projection surface. As long as the degrees of two laser rangefinders 4 are the same, it proves that the ruler 21 and the projection surface are parallel to each other, and the distance between the two laser rangefinders 4 on the ruler 21 is the same as the distance between the projection points of the two laser rangefinders 4 on the projection surface. If the degrees of the laser rangefinder 4 are the same or different, it proves that the ruler 21 and the projection surface are not parallel to each other, and the posture of the entire device needs to be adjusted. The adjustment includes the following aspects:

[0049] 1. Adjust the diagonal brace 32:

[0050] By moving the hoop 33 on the column 31, the height of the top of the diagonal brace 32 can be adjusted. By adjusting the angle of each diagonal brace 32, the inclination of the column 31 can be changed, thereby changing the inclination of the ruler 21.

[0051] 2. Adjust the rotating base 1:

[0052] The bolt 15 is loosened by tightening the handle 13 and the rotating plate 12 is rotated, thereby changing the direction of the through hole of the ruler sleeve 14 and changing the inclination of the ruler 21 .

[0053] 3. Adjust ruler 21:

[0054] By rotating the ruler 21 to make it rotate in the ruler sleeve 14 , the position of the laser rangefinder base 22 is changed, thereby changing the laser projection angle of the laser rangefinder 4 .

[0055] 4. Adjust the laser rangefinder 4:

[0056] By rotating the laser rangefinder base 22 on the ruler 21 , the position of the laser rangefinder 4 can be changed, thereby changing the laser projection angle of the laser rangefinder 4 .

[0057] The use process of the utility model is:

[0058] S1: Place the utility model on the floor of a train compartment, arrange two laser rangefinders 4 at corresponding scales of a ruler 21 according to the drilling positions of the components in the drawing, and one of the laser rangefinders 4 is located at the 0 scale position as a reference.

[0059] S2: Start the two laser rangefinders 4, project the laser onto the top surface of the train compartment, and observe the readings of the two laser rangefinders 4. If they are the same, the distances between the two laser rangefinders 4 and the top surface of the train compartment are the same, the ruler 21 and the top surface of the train compartment are parallel to each other, and the projection position is accurate. If they are not the same, adjust the entire device through the above-mentioned adjustment methods until the readings of the two laser rangefinders 4 are the same.

[0060] For example, adjust the vertical angle of the ruler 21 until the values ​​measured by the two laser rangefinders 4 from the top surface are equal, and fix them with the tightening handle 13. The position of the laser rangefinder 4 at one end is fixed at the 0 scale of the ruler, and the other laser rangefinder 4 is adjusted to the size scale required by the drawing. Arrange the parts according to the target position of the laser projection.

[0061] S3: After that, drill holes according to the projection position and proceed to the next step of installing spare parts.

[0062] The utility model is used for the installation of spare parts on the top surface of the motor vehicle compartment, and can quickly and accurately drill holes for the installation position, and has the following advantages:

[0063] 1. High positioning accuracy avoids the human eye error caused by traditional measuring tape and improves the quality of layout.

[0064] 2. The positioning time is short, which shortens the installation cycle and improves the overall assembly and flow time.

[0065] 3. High safety, avoiding high-altitude operations and significantly reducing operational complexity.

[0066] Of course, the device of the present invention can also be used for arranging and positioning parts for assembling other equipment.

[0067] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
