Description

Technical Field

[0001] This application relates to the field of inspection tool technology, and in particular to a cab mounting bracket inspection tool. Background Technology

[0002] The cab mounting bracket is the foundation for ensuring the normal functioning of the cab. It supports and connects the vehicle frame and the cab, and can withstand unstable loads from the cab and chassis. During assembly, when the cab is lowered, it interferes with the cab mounting bracket, requiring adjustment of the bracket's position.

[0003] To ensure proper assembly, the cab mounting bracket needs to be inspected and calibrated. In the existing technology, since there is no special inspection tool and the mounting bracket has multiple surfaces, the various surfaces of the mounting bracket are inspected by scribing. The inspection requires adjustment of the reference, which is cumbersome and inefficient. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of this application is to provide a cab mounting bracket inspection tool to solve the problem of low inspection efficiency of cab mounting brackets in the prior art.

[0005] To achieve the above and other related objectives, this application provides a cab mounting bracket inspection tool, the mounting bracket having top holes, bottom holes, and wing holes, comprising:

[0006] Base;

[0007] A first detection seat is disposed on the base. A first positioning surface is provided on the top of the first detection seat. A positioning pin for positioning the mounting bracket is provided on the first positioning surface. The positioning pin passes through the bottom hole of the mounting bracket. The bottom of the mounting bracket is in contact with the first positioning surface to position the mounting bracket on the first detection seat.

[0008] A second detection seat is disposed on the base. There is a gap between the second detection seat and the first detection seat. The second detection seat has a second positioning surface on the side close to the first detection seat. The second positioning surface has a first detection hole that passes through the second detection seat in the horizontal direction. The first detection hole is used to detect the hole size of the mounting bracket. When the top of the mounting bracket is positioned on the first detection seat, there is a gap between the top of the mounting bracket and the second positioning surface, and the hole at the top of the mounting bracket is flush with the first detection hole in the horizontal direction.

[0009] A go / no-go gauge is used to extend into the first detection hole for detection;

The third positioning surface is in contact with the wing of the mounting bracket. A second detection hole is opened on the third positioning surface. The hole on the wing of the mounting bracket is flush with the second detection hole in the horizontal direction.

[0014] Optionally, at least two second detection holes are provided, with a gap between adjacent second detection holes.

[0015] Optionally, the cab mounting bracket inspection tool further includes a support base for supporting the mounting bracket, the support base being disposed between the first inspection base and the second inspection base.

[0027] Please see Figures 1 to 3 This application exemplarily provides a cab mounting bracket inspection tool, the mounting bracket having top holes, bottom holes, and wing holes, including:

[0028] Base 1;

[0029] The first detection seat 2 is set on the base 1. The top of the first detection seat 2 is provided with a first positioning surface 3. The first positioning surface 3 is provided with a positioning pin 4 for positioning the mounting bracket 12. The positioning pin 4 passes through the bottom hole of the mounting bracket 12. The bottom of the mounting bracket 12 is in contact with the first positioning surface 3 to position the mounting bracket 12 on the first detection seat 2.

[0030] The second detection seat 5 is disposed on the base 1. There is a gap between the second detection seat 5 and the first detection seat 2. The second detection seat 5 is provided with a second positioning surface 6 on the side close to the first detection seat 2. The second positioning surface 6 is provided with a first detection hole 7 through the second detection seat 5 in the horizontal direction. The first detection hole 7 is used to detect the hole size of the mounting bracket 12. When the top of the mounting bracket 12 is positioned on the first detection seat 2, there is a gap between the top of the mounting bracket 12 and the second positioning surface 6, and the hole at the top of the mounting bracket 12 is flush with the first detection hole 7 in the horizontal direction.

[0031] The go / no-go gauge 8 is used to extend into the first inspection hole 7 for inspection;

[0032] Detection block 9 is used to insert into the gap for detection.

[0033] In the cab mounting bracket inspection fixture provided in this application, the installation position of the mounting bracket 12 is simulated by the first inspection seat 2 and the second inspection seat 5. The top of the mounting bracket 12 is positioned on the first inspection seat 2 by the positioning pin 4. The gap between the top of the mounting bracket 12 and the second inspection seat 5 simulates the reserved gap during installation. The go / no-go gauge 8 is inserted into the first inspection hole 7 and the hole on the top of the mounting bracket 12 in sequence to detect the hole size on the top of the mounting bracket 12. The inspection block 9 is inserted into the gap between the top of the mounting bracket 12 and the second inspection seat 5 to detect the gap size of the mounting bracket 12, thereby improving the inspection efficiency.

[0034] It should be noted that in actual assembly, if the gap between the cab and the mounting bracket 12 does not meet the requirements, the cab will interfere with the mounting bracket 12 when it falls, affecting the assembly. The mounting bracket 12 has a profile including a web 15, a wing 16, and a top surface 17. The web 15 is located at the bottom of the mounting bracket 12 and serves as a positioning surface during assembly. The wing 16 is located on the wing of the mounting bracket 12 and is adjacent to the web 15. The top surface 17 is located at the top of the mounting bracket 12. Since the web 15, wing 16, and top surface 17 of the mounting bracket 12 are not at the same horizontal level, the existing inspection method requires each surface to be inspected separately. The reference for each surface needs to be adjusted, which makes the inspection operation cumbersome and prone to misalignment. Furthermore, due to the large size of the mounting bracket 12, it is necessary to position the mounting bracket 12 with a pin during inspection. However, the pin positioning method is prone to product slippage and injury, posing a significant safety and quality hazard.

[0035] In some embodiments, at least four positioning pins 4 are provided, and the positioning pins 4 are arrayed on the first positioning surface 3. During testing, the mounting bracket 12 passes through the positioning pins 4 through the holes on the width 15 until the width 15 is in contact with the first positioning surface 3, so as to position the mounting bracket 12 on the first testing seat 2.

[0036] In this embodiment, at least four first detection holes 7 are provided, and the array of first detection holes 7 is distributed on the second positioning surface 6. Specifically, the top surface 17 of the mounting bracket 12 is the mounting surface. During the actual assembly process, the cab is lowered, and the mounting holes of the top surface 17 of the mounting bracket 12 are assembled with the cab by fasteners. The first detection seat 2 and the second detection seat 5 simulate the vehicle mounting position. There is a gap between the top surface 17 of the mounting bracket 12 and the second positioning surface 6. The thickness of the detection block 9 is the minimum gap that ensures no interference between the cab and the mounting bracket 12. If the detection block 9 cannot be inserted into the gap between the top surface 17 of the mounting bracket 12 and the second positioning surface 6, the gap size does not meet the assembly requirements and needs to be corrected. If the detection block 9 can be inserted into the gap between the top surface 17 of the mounting bracket 12 and the second positioning surface 6, the gap size meets the assembly requirements. At the same time, the size of the mounting hole of the top surface 17 of the mounting bracket 12 is detected by sequentially inserting the go / no-go gauge 8 into the first detection hole 7 and the mounting hole of the top surface 17 of the mounting bracket 12.

[0037] In the above embodiment, the first detection seat 2 has a third positioning surface 13 on the side near the second detection seat 5. The third positioning surface 13 is in close contact with the wing of the mounting bracket 12. A second detection hole 14 is opened on the third positioning surface 13. The wing hole of the mounting bracket 12 is flush with the second detection hole 14 in the horizontal direction. Specifically, during testing, the mounting bracket 12 is positioned on the first detection seat 2. If the size of the wing surface 16 meets the assembly requirements, the wing surface 16 of the mounting bracket 12 is in contact with the third positioning surface 13. If the size of the wing surface 16 does not meet the assembly requirements, the wing of the mounting bracket 12 is in close contact with the third positioning surface 13. The surface 16 and the third positioning surface 13 cannot be perfectly aligned, resulting in a gap. Since the dimensions of the wing surface 16 and the gap are in the same horizontal direction, the dimensions of the wing surface 16 will affect the gap between the top surface 17 of the mounting bracket 12 and the second positioning surface 6. The inspection of the wing surface 16 and the third positioning surface 13 of the mounting bracket 12 is also a further inspection of the gap between the top surface 17 of the mounting bracket 12 and the second positioning surface 6. At the same time, by inserting the go / no-go gauge 8 into the wing hole and the second inspection hole 14 of the mounting bracket 12 in sequence, the assembly hole dimensions of the wing surface 16 of the mounting bracket 12 are inspected.

[0038] It is understood that at least two second detection holes 14 are provided, with a gap between adjacent second detection holes 14. The mounting bracket 12 has two mounting holes on the wing surface 16, four on the width surface 15, and four on the top surface 17. The number of positioning pins 4, first detection holes 7, and second detection holes 14 can be increased according to actual needs, enabling simultaneous detection of multiple mounting brackets 12 and improving detection efficiency.

[0039] In this embodiment, the cab mounting bracket 12 inspection tool also includes a support seat 10 for supporting the mounting bracket 12. The support seat 10 is disposed between the first inspection seat 2 and the second inspection seat 5. Since the mounting bracket 12 is large in size, the support seat 10 provides auxiliary support, which facilitates the positioning operation of the mounting bracket 12 on the first inspection seat 2.

[0040] In the above embodiment, the support base 10 and the second detection base 5 are connected by a support plate 11, and the support base 10 and the second detection base 5 are connected by the support plate 11 to enhance the stability of the overall structure.

[0041] Specifically, the horizontal height of the second detection seat 5 is greater than that of the support seat 10, and the horizontal height of the support seat 10 is greater than that of the first detection seat 2.

[0042] In this embodiment, when the mounting bracket 12 is positioned on the first detection seat 2, there is a gap between the positioning pin 4 and the bottom hole of the mounting bracket 12, which facilitates the positioning and placement of the mounting bracket 12 on the first detection seat 2.

[0043] In summary, in the cab mounting bracket inspection fixture provided in this application, the first inspection seat 2 and the second inspection seat 5 simulate the vehicle installation position of the mounting bracket 12. The top of the mounting bracket 12 is positioned on the first inspection seat 2 by the positioning pin 4. The gap between the top of the mounting bracket 12 and the second inspection seat 5 simulates the reserved gap during vehicle installation. The go / no-go gauge 8 is inserted into the first inspection hole 7 and the hole on the top of the mounting bracket 12 in sequence to detect the hole size on the top of the mounting bracket 12. The inspection block 9 is inserted into the gap between the top of the mounting bracket 12 and the second inspection seat 5 to detect the gap size of the mounting bracket 12, thereby improving the inspection efficiency.

[0044] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
