Description

Technical Field

[0001] The invention belongs to the technical field of application of measuring tools, and particularly relates to a combined go gauge for a profile groove. Background Art

[0002] The existing skylights of automobiles are all electrically opened, so corresponding guide rails need to be matched. Due to the design requirements of automobiles, the guide rail grooves are designed in various shapes. It is particularly important to inspect the dimensions of the grooves in the guide rail forming parts. When using general measuring tools for measurement, the measurement speed is relatively slow. Therefore, it is necessary to design a go gauge that can quickly detect the dimensions of the grooves in the guide rail forming parts.

[0003] Chinese Utility Model Patent with Publication No. CN220829151U discloses a slide rail groove gauge. The gauge includes a handheld part and a detection part, and the detection part is connected to the handheld part. The slide rail groove gauge is divided into a go gauge and a not-go gauge according to different dimensions of the detection part; the size of the maximum longitudinal section of the detection part of the go gauge is adapted to the maximum material size of the slide rail groove to be measured; the size of the maximum longitudinal section of the detection part of the not-go gauge is adapted to the minimum material size of the slide rail groove to be measured. Since there may be certain errors in the manufacturing process of the guide rail and the assembly of the go gauge and the guide rail, and during the process of pressing and forming the guide rail, or due to changes in factors such as temperature and pressure, the parts may undergo slight deformations within an acceptable range. However, the detection size of the go gauge in this solution is single and has no fault tolerance, and it cannot adapt to some slight changes within the dimensional tolerance range of the workpiece to be detected, and there is a risk of hard contact with the workpiece to be detected. At the same time, when detecting multiple workpieces, due to the possible slight deformations at different positions and sizes of multiple workpieces, the time for adjustment and calibration is relatively long when the go gauge detects multiple workpieces, resulting in a slow detection efficiency. Summary of the Invention

[0004] The purpose of the invention is to provide a combined go gauge for a profile groove with good adaptability and fast detection efficiency.

[0005] To achieve the above purpose, the combined go gauge for a profile groove provided by the utility model includes a support member and a detection assembly connected to each other; the support member includes a handheld part and a mounting part connected to each other, and the detection assembly includes a first detection member; the mounting part is provided with a first mounting hole and a first limiting part, the first detection member is installed in the first mounting hole, the first detection end of the first detection member extends out of the mounting part, and the first limiting part is in limiting cooperation with the first detection member in the axial direction of the first mounting hole; the first limiting part is located in the first mounting hole, and there is a first axial movement gap between the first detection member and the first limiting part in the axial direction of the first mounting hole; and / or there is a first radial movement gap between the first detection member and the first mounting hole in the radial direction of the first mounting hole.

[0006] As can be seen from the above, by setting the first axial movement clearance, when the go - gauge detects the guide rail groove, it can adapt to the small errors of the workpiece to be detected in the first axial direction. There is a first radial movement clearance between the first detecting member and the first mounting hole in the radial direction of the first mounting hole, so that the go - gauge can adapt to the small errors of the workpiece to be detected in the first radial direction, improving the applicability of the go - gauge and the accuracy of detection. It prevents hard contact between the go - gauge and the workpiece during the movement of the go - gauge, resulting in damage to the go - gauge or the workpiece and a decrease in the measurement accuracy of the go - gauge.

[0007] A further solution is that the detection assembly further includes a second detecting member, and the second detecting member is arranged at an interval from the first detecting member; a second mounting hole and a second limiting portion are further provided on the mounting portion. The axial direction of the second mounting hole is parallel to the axial direction of the first mounting hole. The second detecting member is mounted in the second mounting hole, and the second detecting end of the second detecting member extends out of the mounting portion. The second limiting portion is in limiting cooperation with the second detecting member in the axial direction of the second mounting hole; the second limiting portion is located in the second mounting hole, and there is a second axial movement clearance between the second detecting member and the second limiting portion in the axial direction of the second mounting hole; and / or there is a second radial movement clearance between the second detecting member and the second mounting hole in the radial direction of the second mounting hole.

[0008] As can be seen from the above, by setting the second detecting member, it is convenient to perform multi - slot detection on a guide rail with a complex shape, and can further improve the performance of the go - gauge in detecting complex workpieces. At the same time, by setting the second axial movement clearance and the second radial movement clearance, the go - gauge can adapt to the small errors of the workpiece to be detected in the second axial direction and the second radial direction.

[0009] A further solution is that the detection assembly further includes a limiting member. The first limiting portion and the second limiting portion are respectively located at both ends of the limiting member. A mounting groove is provided on the mounting portion, and the first mounting hole and the second mounting hole are both communicated with the mounting groove. The limiting member is detachably mounted in the mounting groove.

[0010] As can be seen from the above, by setting one limiting member, the limitation of both the first detecting member and the second detecting member can be realized simultaneously, thereby reducing the components of the go - gauge, making the structure simple and convenient for production. At the same time, the provided limiting groove facilitates installation and assembly.

[0011] A further solution is that a first limiting groove is formed at one end of the first detecting member away from the first detecting end. The first limiting groove is recessed radially from the outer peripheral wall of the first detecting member, and the first limiting portion extends radially into the first limiting groove along the first detecting member.

[0012] As can be seen from the above, by providing the first limiting groove, it is convenient for the first detecting member to extend into the first limiting groove, with a simple structure and convenient assembly.

[0013] A further solution is that the first limiting groove extends along the circumferential direction of the first detecting member.

[0014] As can be seen from the above, the first limiting groove extends along the circumferential direction of the first detecting member, so that there is no need to rotate the first limiting groove to the corresponding position, which is convenient for disassembly and assembly.

[0015] A further solution is that a second limiting groove is provided at one end of the second detecting member away from the second detecting end, the second limiting groove is recessed radially from the outer peripheral wall of the second detecting member, and the second limiting portion extends radially into the second limiting groove along the second detecting member; the second limiting groove extends along the circumferential direction of the second detecting member.

[0016] As can be seen from the above, the installation can be simplified by providing the limiting groove extending along the circumferential direction of the second detecting member.

[0017] A further solution is that the first detecting member includes a first detecting mounting portion, a first detecting portion, and a second detecting portion connected in sequence along the axial direction, the first limiting portion is in limiting cooperation with the first detecting mounting portion, the first detecting mounting portion is located in the first mounting hole, and both the first detecting portion and the second detecting portion are located outside the first mounting hole and at the first detecting end.

[0018] A further solution is that the second detecting portion is spherical-crowned; and / or the first detecting portion is cylindrical.

[0019] As can be seen from the above, the spherical-crowned second detecting portion is convenient for measuring multiple dimensions of a groove with a special structure. At the same time, the first detecting member is cylindrical, which is convenient for the movement of the go gauge.

[0020] A further solution is that a fifth detecting portion is further provided on the mounting portion; the fifth detecting portion includes a first detecting wall, a second detecting wall, a third detecting wall, a fourth detecting wall, and a fifth detecting wall connected in sequence, the first detecting wall and the fifth detecting wall are both oppositely arranged with respect to the third detecting wall, and the second detecting wall and the fourth detecting wall are oppositely arranged; the fourth detecting wall is closer to the first detecting end than the second detecting wall, the first mounting hole is recessed inward from the fourth detecting wall, and the axial direction of the first mounting hole is parallel to the normal direction of the second detecting wall; in the axial direction of the first mounting hole, the hand-held portion is located between the first detecting wall and the fifth detecting wall.

[0021] As can be seen from the above, the provided fifth detecting portion can further improve and enrich the measuring parts of the go gauge, which is convenient for meeting the measuring requirements of different guide grooves.

[0022] A further solution is that the installation part is further provided with a sixth detection part, which is located on the third detection wall and recesses inward from the third detection wall, and the extending direction of the sixth detection part is perpendicular to the axial direction of the first installation hole.

[0023] As can be seen from the above, by setting the sixth detection part, the detection function of the go gauge is further improved, so as to meet the detection requirements of various parts of the complex guide rail groove.

[0024] In summary, the combined go gauge for the profile groove of the present utility model has good adaptability, fast detection efficiency, and can detect the sizes of various parts of the profile groove with complex structures. Description of the Drawings
