Description

Technical Field

[0001] This utility model relates to a gauge, and more particularly to a position gauge for the shaft of an automotive seat adjustment handle. Background Technology

[0002] Car seats are typically equipped with adjustable seat assemblies, which are adjusted using an adjustment handle. The adjustment handle is connected to the seat assembly via an adjustment handle shaft A. The two parts on the adjustment handle shaft A that connect to the adjustment handle and the seat assembly are a square-shaped first connecting part A1 at the head and a second connecting part A2 with four protruding teeth A21. The first connecting part A1 and the second connecting part A2 are connected by a cylindrical connecting section A3 with a slightly larger outer diameter (e.g., ...). Figure 1 As shown in the figure, the four end faces of the first connecting part A1 have positional requirements. However, in the actual manufacturing process, the positional accuracy of this part can only be determined by the positional accuracy of the original inspection fixture itself.

[0025] As shown in the figure, a position measurement tool for an automotive seat adjustment handle shaft includes a first inspection seat 2 and a second inspection seat 3 spaced apart on an inspection base plate 1. The first inspection seat 2 is used to position and install the adjustment handle shaft A and to inspect the position of the second connecting part A2 of the adjustment handle shaft A. An angle scale 31 is provided on the second inspection seat 3. An inspection pointer 4 is detachably mounted between the first inspection seat 2 and the second inspection seat 3. The two ends of the inspection pointer 4 are an indicating end 41 for cooperating with the angle scale 31 and an inspection end 42 for cooperating with the first connecting part A1 for inspection. The inspection end 42 is provided with a square inspection hole 43 that runs vertically through the shaft and meets the position measurement qualification standard of the first connecting part A1. The diagonal of the inspection hole 43 is perpendicular to the axis of the inspection pointer 4.

[0026] The adjusting handle shaft A is positioned and installed on the first inspection seat 2, so that the square first connecting part A1 of the adjusting handle shaft A extends out of the first inspection seat 2. The inspection hole 43 is fitted onto the first connecting part A1. By moving the inspection pointer 4, the reading on the angle scale 31 corresponding to the indicator end 41 is read to obtain the positional data of the first connecting part A1.

[0027] In this specific embodiment, the inspection end 42 is provided with an inspection block 5 having an inspection hole 43, and the inspection block 5 is detachably disposed on the inspection end 42. This enables the inspection tool to have better versatility; by replacing the inspection block 5 with different inspection holes 43, it can be adapted for the inspection of the first connecting part A1 of different sizes.

[0028] In this specific embodiment, the inspection end 42 has a through-hole cavity 40 for installing the inspection block 5. The inspection block 5 is embedded in the cavity 40. A positioning mechanism for positioning the installation position of the inspection block 5 and a locking mechanism for locking the installation position of the inspection block 5 are provided between the inspection end 42 and the inspection block 5. The structure is simple and easy to assemble and disassemble.

[0029] In this specific embodiment, the positioning mechanism includes a groove 51 disposed on the inspection block 5 and a protrusion 401 disposed in the mounting cavity 40 that mates with the groove 51. The groove 51 is recessed on the two opposite side end faces of the inspection block 5, and the groove 51 extends vertically. The protrusion 401 is disposed on the two inner side end faces of the mounting cavity 40. The inspection block 5 is positioned and installed in the mounting cavity 40 by the protrusion 401 being embedded in the corresponding groove 51. The structure is simple and the positioning is stable.

[0030] In this specific embodiment, the locking mechanism includes a locking rod 6, one end of which has an external thread. A locking hole 46 communicating with the mounting cavity 40 is provided on the right side of the inspection end 42. A locking screw hole 52 is fitted onto the right end face of the inspection block 5. The threaded end of the locking rod 6 passes through the locking hole 46 and is screwed into the locking screw hole 52, thereby locking the installation position of the inspection block 5. The structure is simple and achieves stable position locking.

[0031] In this specific embodiment, a pointer knob 7 is provided at the other end of the locking lever 6. The pointer knob 7 serves two purposes: firstly, it can move the pointer, and secondly, it facilitates the assembly and disassembly of the locking lever 6.

[0032] In this specific embodiment, the inspection base plate 1 is provided with a support seat 8 for placing the inspection pointer 4. The support seat 8 has a raised support post 81, and the inspection pointer 4 has a corresponding support hole 47. When not in use, the inspection pointer 4 is positioned and placed by fitting it onto the corresponding support post 81 through the support hole 47. In this way, the inspection pointer 4 can be neatly stored when not in use, preventing loss.

[0033] In this specific embodiment, a square cavity 21 is provided inside the first inspection seat 2, and an installation hole 22 is provided on the first inspection seat 2, which communicates with the cavity 21 and allows the second connecting part A2 to be inserted and installed. The inner diameter of the installation hole 22 is smaller than the outer diameter of the connecting section A3. After the adjusting handle shaft A is positioned and installed, the connecting section A3 is located on the upper end surface of the first inspection seat 2.

[0034] A rectangular inspection seat 9 is provided inside the cavity 21. The rectangular inspection seat 9 has a vertically extending inspection cavity 91 into which the second connecting part A2 can extend. The inspection cavity 91 has an inspection section that meets the positional accuracy standards of the second connecting part A2. The structure is simple, and it simultaneously achieves the positioning and installation of the adjusting handle shaft A while also simultaneously inspecting the positional accuracy of the second connecting part A2.

[0035] In this specific embodiment, a test ring 911 is coaxially protruding within the test cavity 91, and four recessed portions 912 are evenly distributed and spaced along the circumference of the test ring 911, forming a test section. This structure constitutes a test section that meets the positional accuracy standard of the second connection portion A2; it is simple in structure and easy to manufacture.

[0036] In this specific embodiment, a support spring 10 is provided below the rectangular inspection seat 9. Under the action of the support spring 10, the rectangular inspection seat 9 can move up and down within the cavity 21. It can also be used for similar parts of different lengths without the need to replace other devices, thus improving its versatility.

[0037] The specific inspection method is as follows: First, check the position of the second connecting part A2 of the adjusting handle shaft A. Pass the second connecting part A2 through the mounting hole 22, allowing the toothed portion to enter the inspection chamber. If the position is not up to standard, the second connecting part A2 will not be in place and will jam, requiring no further inspection. If the position is up to standard, the second connecting part A2 will enter the inspection chamber and engage with it, while the lower end face of the connecting section A3 will be tightly engaged with the upper end face of the first inspection seat 2. At this point, the first connecting part A1 will be exposed outside the first inspection seat 2. Then, install the inspection pointer 4. The inspection hole 43 is fitted onto the first connecting part A1. If the position of this part is not up to standard, it will get stuck if it is not fitted in place, and no further inspection is required. If the position of this part is up to standard, the first connecting part A1 can enter into the inspection hole 43 and fit with it. At the same time, the lower end face of the inspection block 5 fits tightly with the upper end face of the connecting section A3. At this time, the indicator end 41 is set on the angle scale 31. By operating the pointer dial 7, the inspection pointer 4 can be gently turned clockwise or counterclockwise to read the scale on the angle scale 31 and record it. If the reading is within ±2°, the product is considered qualified; otherwise, it is unqualified.
