Description

Technical Field

[0001] This application relates to the field of testing tooling, and in particular to a steering column cover inspection tool. Background Technology

[0002] The upper and lower steering column covers are housing structures used to protect the steering column. When assembled, they effectively prevent dust, water, and other contaminants from entering the steering column. Typically, the upper and lower covers are secured with screws, requiring the mounting holes on the upper and lower covers to align properly. Therefore, after manufacturing, the hole spacing of both the upper and lower covers must be checked to ensure it is appropriate.

[0003] In related technologies, when measuring the distance between two mounting holes of an upper or lower housing, the measuring personnel first measure the distance between the edges of the two mounting holes using a vernier caliper, then measure the diameter of each mounting hole separately, and finally calculate the distance between the two mounting holes. This results in relatively low efficiency in measuring the distance between the mounting holes. Summary of the Invention

[0004] To improve the efficiency of measuring the hole spacing of the mounting holes of the upper or lower cover, this application provides a steering column cover inspection tool.

[0005] The steering column cover inspection tool provided in this application adopts the following technical solution: A steering column cover inspection tool includes a base and further includes: a first mating member fixed to the base, the first mating member being coaxially mated with one of the mounting holes on the cover; a sliding member slidably connected to the base, the sliding direction being towards or away from the first mating member; a second mating member connected to the sliding member, the second mating member being coaxially mated with another mounting hole on the cover; a scale fixed to the base; and a distance indicator connected to the sliding member, the distance indicator cooperating with the scale to indicate the sliding distance of the second mating member relative to the first mating member.

[0006] By adopting the above technical solution, when workers need to use a gauge to measure the distance between two mounting holes on the housing, they first insert the end of the first mating part into one of the mounting holes, making the axis of the first mating part and the axis of that mounting hole coaxial. Then, they move the second mating part, inserting its end into the other mounting hole, making the axis of the second mating part and the axis of that mounting hole coaxial. With this configuration, the sliding distance of the second mating part relative to the first mating part is the distance between the axes of the two mounting holes. The distance between the two mounting holes can be obtained by reading the scale indicated by the distance indicator.

[0007] When workers use this gauge to measure the distance between two mounting holes on a housing, they can directly read the distance without needing to calculate it indirectly, thus improving the efficiency of mounting hole distance measurement. Furthermore, since the distance between the two mounting holes can be obtained directly with a single measurement, compared to existing technologies, it reduces cumulative measurement errors, thereby improving the accuracy of mounting hole distance measurement.

[0008] In some embodiments, the first mating member includes a first mating portion, which is semi-conical and gradually tapers away from the base; the second mating member includes a second mating portion, which is semi-conical and gradually tapers away from the sliding member; when the first mating portion and the second mating portion are fitted together, the center of the end of the first mating portion and the center of the end of the second mating portion coincide.

[0009] By adopting the above technical solution, when the first and second mating parts are fitted together, the distance between the center of the ends of the first and second mating parts is 0. This allows the scale to start from zero, facilitating readings by the operator. Simultaneously, the measurement range of the mounting hole spacing can also start from 0, increasing the measurement range of the mounting hole spacing.

[0010] In some embodiments, the base includes a mounting cavity, and the sliding member is located within the mounting cavity; the sliding member is provided with a first guide wheel and a second guide wheel spaced apart along a first direction, and both the first guide wheel and the second guide wheel are in contact with the inner wall of the mounting cavity; the sliding member is provided with a third guide wheel and a fourth guide wheel spaced apart along a second direction, and both the third guide wheel and the fourth guide wheel are in contact with the inner wall of the mounting cavity, wherein the first direction and the second direction intersect.

[0011] By adopting the above technical solution, the measurement accuracy of the mounting hole spacing of this inspection fixture is improved. At the same time, the friction between the sliding parts and the base is reduced by the action of the guide wheels.

[0012] In some embodiments, the first guide wheel and the second guide wheel are staggered along the sliding direction of the sliding member; the third guide wheel and the fourth guide wheel are staggered along the sliding direction of the sliding member.

[0013] By adopting the above technical solution, misalignment between the first and second mating parts in the width and height directions of the base is further avoided, and the measurement accuracy of the mounting hole distance of this inspection tool is further improved.

[0014] In some embodiments, the sliding member includes a first sliding portion and a second sliding portion, two first sliding portions are spaced apart, and the second sliding portion is located between the two first sliding portions. Both first sliding portions are connected to the second sliding portion. The first guide wheel and the second guide wheel are respectively connected to the two first sliding portions, and the third guide wheel and the fourth guide wheel are both connected to the second sliding portion.

[0015] By adopting the above technical solution, the first guide wheel and the second guide wheel are connected by two spaced-apart first sliding parts, and the third guide wheel and the fourth guide wheel are both connected by second sliding parts. The first and second guide wheels are connected by independent parts, facilitating adjustment of the distance between the two first sliding parts, ensuring that both the first and second guide wheels are in contact with the inner wall of the mounting cavity. The adjustment of the third and fourth guide wheels does not interfere with the first sliding parts, and also facilitates the adjustment of the distance between the third and fourth guide wheels, ensuring they are in contact with the inner wall of the mounting cavity.

[0016] In some embodiments, the second sliding portion includes two clamping plates, both of which clamp the third guide wheel and the fourth guide wheel; the two first sliding portions clamp the second sliding portion, and the clamping direction is the same as the clamping direction of the two clamping plates.

[0017] By adopting the above technical solution, in actual production, a screw can be used to connect the large end of the screw to one of the first sliding parts, and the threaded end of the screw can pass through two clamping plates at once and then connect to the other first sliding part, thereby simplifying the installation steps of the sliding parts and facilitating the installation of the sliding parts.

[0018] In some embodiments, the mounting cavity includes a first inner wall, a second inner wall, a third inner wall, and a fourth inner wall, wherein the first inner wall and the second inner wall are arranged in parallel opposite directions, and the third inner wall and the fourth inner wall are arranged in parallel opposite directions; the normal of the first inner wall is along the first direction, and the normal of the third inner wall is along the second direction.

[0019] By adopting the above technical solution, the first inner wall, the second inner wall, the third inner wall and the fourth inner wall form an enclosure around the sliding member, which can achieve stable positioning of the sliding member in the first direction and the second direction.

[0020] In some embodiments, the base includes a first bent plate and a second bent plate connected to each other, the first inner wall and the third inner wall are disposed on the first bent plate, and the second inner wall and the fourth inner wall are disposed on the second bent plate.

[0021] In some embodiments, an installation gap is provided between the first inner wall and the fourth inner wall, and the first inner wall moves closer to or further away from the fourth inner wall along the first direction; the distance indicator includes a connector, one end of which is connected to the sliding member, and the other end of which extends out of the base through the installation gap.

[0022] By adopting the above technical solution, the existence of the installation gap facilitates the adjustment of the distance between the first inner wall and the fourth inner wall, thereby allowing the first guide wheel and the second guide wheel to respectively conform to the first inner wall and the fourth inner wall. Simultaneously, the installation gap facilitates the connection of the connecting piece and the sliding piece, allowing them to extend beyond the base. Therefore, the installation gap not only facilitates the adjustment of the distance between the first inner wall and the fourth inner wall but also facilitates the connection between the connecting piece and the sliding piece.

[0023] In some embodiments, the first bent plate is provided with a fixing member, one end of which is connected to the first bent plate, and the other end of which passes through the installation gap and is connected to the second bent plate.

[0024] By adopting the above technical solution, the fixing component achieves the connection between the first bent plate and the second bent plate. At the same time, when the second mating component slides away from the first mating component via the sliding component, the fixing component can limit the connection, thereby preventing the sliding component from slipping off the base.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. When workers use this gauge to measure the distance between two mounting holes on a housing, they can directly read the distance between the two mounting holes without having to calculate it indirectly, thus improving the efficiency of measuring the hole distance. Furthermore, since the hole distance between the two mounting holes can be obtained directly with a single measurement, compared to existing technologies, it reduces the cumulative error caused by measurement, thereby improving the accuracy of the hole distance measurement. 2. The first and second guide wheels are connected by independent parts, which facilitates the adjustment of the distance between the two first sliding parts, ensuring that both the first and second guide wheels are in contact with the inner wall of the mounting cavity. The adjustment of the third and fourth guide wheels does not interfere with the first sliding parts, and also facilitates the adjustment of the distance between the third and fourth guide wheels, ensuring that the third and fourth guide wheels are in contact with the inner wall of the mounting cavity; 3. The installation gap facilitates adjustment of the distance between the first and fourth inner walls, allowing the first and second guide wheels to fit against the first and fourth inner walls respectively. Simultaneously, the installation gap facilitates the connection of the connecting piece and the sliding piece, allowing it to extend beyond the base. Therefore, the installation gap not only facilitates adjustment of the distance between the first and fourth inner walls but also facilitates the connection between the connecting piece and the sliding piece.

Detailed Implementation

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0037] Reference Figures 1-4 This application discloses an embodiment of a steering column cover inspection tool, which includes a base 1, a first mating part 2, a sliding part 3, a second mating part 4, a scale 5, and a distance indicator 6. The first mating part 2 is fixed to the base 1 and is used for coaxial engagement with one of the mounting holes 91 on the cover 9. The sliding part 3 is slidably connected to the base 1, and the sliding direction is along the direction of approaching or moving away from the first mating part 2. The second mating part 4 is connected to the sliding part 3 and is used for coaxial engagement with another mounting hole 91 on the cover 9. The scale 5 is fixed to the base 1, and the distance indicator 6 is connected to the sliding part 3. The distance indicator 6 and the scale 5 cooperate to indicate the sliding distance of the second mating part 4 relative to the first mating part 2.

[0038] When the operator needs to use a gauge to measure the distance between the two mounting holes 91 on the housing 9, firstly, the end of the first mating part 2 is inserted into one of the mounting holes 91, making the axis of the first mating part 2 and the axis of the mounting hole 91 coaxial. Then, the second mating part 4 is moved, and the end of the second mating part 4 is inserted into the other mounting hole 91, making the axis of the second mating part 4 and the axis of the mounting hole 91 coaxial. With this configuration, the sliding distance of the second mating part 4 relative to the first mating part 2 is the distance between the axes of the two mounting holes 91. The distance between the two mounting holes 91 can be obtained by reading the scale on the distance indicator 6.

[0039] Therefore, when workers use this gauge to measure the distance between the two mounting holes 91 on the housing 9, they can directly read the distance between the two mounting holes 91 without having to calculate it indirectly, thus improving the efficiency of measuring the hole distance. Furthermore, since the hole distance between the two mounting holes 91 can be obtained directly with just one measurement, compared to existing technologies, the cumulative error caused by measurement is reduced, thereby improving the measurement accuracy of the hole distance.

[0040] Furthermore, refer to Figure 5 , Figure 6The first mating component 2 includes a first mating portion 21, which is semi-conical and gradually tapers away from the base 1, with a pointed end. The second mating component 4 includes a second mating portion 41, which is also semi-conical and gradually tapers away from the sliding component 3, with a pointed end. When the first mating portion 21 and the second mating portion 41 are fitted together, the center of the end of the first mating portion 21 and the center of the end of the second mating portion 41 coincide. In some embodiments, the first mating portion 21 and the second mating portion 41 are arranged in a mirror-symmetrical manner, and when the first mating portion 21 and the second mating portion 41 are fitted together, they form a complete cone shape.

[0041] With this configuration, when the first mating part 21 and the second mating part 41 are engaged, the distance between the center of their ends is zero. This allows the scale 5 to start from zero, facilitating readings. Simultaneously, the measurement range of the hole spacing of the mounting hole 91 can also start from zero, increasing the measurement range of the hole spacing of the mounting hole 91. When the first mating part 21 and the mounting hole 91 are engaged, and the second mating part 41 and the mounting hole 91 are engaged, the self-centering effect of the cone ensures that the center of the first mating part 21 and the center of the mounting hole 91 are concentric, and vice versa. It should be noted that the maximum diameter of both the first mating part 21 and the second mating part 41 must be greater than the diameter of the mounting hole 91 to ensure proper engagement between the conical surfaces of the first mating part 21 and the mounting hole 91.

[0042] In some implementations, reference continues. Figure 5 , Figure 6 The first mating component 2 also includes a first support column 22, which is integrally formed with the first mating part 21. One end of the first support column 22 is connected to the sliding component 3, and the other end is connected to the first mating part 21. The first support column 22 is semi-cylindrical in shape. The second mating component 4 also includes a second support column 42, which is integrally formed with the second mating part 41. One end of the second support column 42 is connected to the sliding component 3, and the other end is connected to the second mating part 41. The second support column 42 is semi-cylindrical in shape. Thus, after the first mating component 2 and the second mating component 4 are fitted together, the first support column 22 and the second support column 42 are assembled into a complete cylinder, and the first mating part 21 and the second mating part 41 are assembled into a complete cone.

[0043] Specifically, refer to Figure 1 and Figure 5The base 1 includes a mounting cavity 11, and a sliding member 3 is located within the mounting cavity 11. The sliding member 3 is provided with a first guide wheel 31 and a second guide wheel 32 spaced apart along a first direction, both of which are in contact with the inner wall of the mounting cavity 11. The sliding member 3 is also provided with a third guide wheel 33 and a fourth guide wheel 34 spaced apart along a second direction, both of which are in contact with the inner wall of the mounting cavity 11. The first and second directions intersect.

[0044] For ease of explanation, the height direction of base 1 (or the height direction of the first mating part 2 and the second mating part 4) is the first direction, and the width direction of base 1 is the second direction. Furthermore, for ease of actual machining, the first and second directions are perpendicular to each other.

[0045] With this configuration, along the height direction of the base 1, the sliding member 3 is limited by the first guide wheel 31 and the second guide wheel 32. Along the width direction of the base 1, the sliding member 3 is limited by the third guide wheel 33 and the fourth guide wheel 34. This restricts the movement of the sliding member 3 in both the height and width directions of the base 1, reducing misalignment of the first mating member 2 and the second mating member 4 in both directions, thereby improving the measurement accuracy of the mounting hole 91 distance by this inspection fixture. Simultaneously, the friction between the sliding member 3 and the base 1 is reduced by the action of each guide wheel.

[0046] Furthermore, refer to Figure 5 , Figure 6 , Figure 7 Along the sliding direction of the sliding member 3, the first guide wheel 31 and the second guide wheel 32 are alternately arranged. Along the sliding direction of the sliding member 3, the third guide wheel 33 and the fourth guide wheel 34 are alternately arranged.

[0047] Because the first guide wheel 31 and the second guide wheel 32 are staggered along the sliding direction of the sliding member 3, the first guide wheel 31 and the second guide wheel 32 prevent the sliding member 3 from twisting about the width direction of the base 1. Because the third guide wheel 33 and the fourth guide wheel 34 are staggered along the sliding direction of the sliding member 3, the third guide wheel 33 and the fourth guide wheel 34 prevent the sliding member 3 from twisting about the height direction of the base 1. This arrangement further prevents misalignment between the first mating member 2 and the second mating member 4 in the width and height directions of the base 1, further improving the measurement accuracy of the mounting hole 91 distance by this inspection tool.

[0048] Furthermore, refer to Figure 4 , Figure 5 , Figure 6The sliding member 3 includes a first sliding part 35 and a second sliding part 36. Two first sliding parts 35 are spaced apart along the height direction of the base 1. The second sliding part 36 is located between the two first sliding parts 35, and both first sliding parts 35 are connected to the second sliding part 36. A first guide wheel 31 and a second guide wheel 32 are respectively connected to the two first sliding parts 35, and a third guide wheel 33 and a fourth guide wheel 34 are both connected to the second sliding part 36.

[0049] With this configuration, the first guide wheel 31 and the second guide wheel 32 are connected by two spaced-apart first sliding parts 35, while the third guide wheel 33 and the fourth guide wheel 34 are both connected by second sliding parts 36. The connection of the first guide wheel 31 and the second guide wheel 32 via independent parts facilitates adjustment of the distance between the two first sliding parts 35, ensuring that both the first guide wheel 31 and the second guide wheel 32 are in contact with the inner wall of the mounting cavity 11. The adjustment of the third guide wheel 33 and the fourth guide wheel 34 does not interfere with the first sliding parts 35, and also facilitates the adjustment of the distance between the third guide wheel 33 and the fourth guide wheel 34, ensuring that they are in contact with the inner wall of the mounting cavity 11.

[0050] Specifically, refer to Figure 5 , Figure 6 The second sliding part 36 includes two clamping plates 361, each clamping a third guide wheel 33 and a fourth guide wheel 34. Two first sliding parts 35 clamp the second sliding part 36, with the clamping direction being the same as that of the clamping plates 361. Specifically, the two clamping plates 361 are arranged vertically along the height direction of the base 1, and the axes of the third guide wheel 33 and the fourth guide wheel 34 are both along the height direction of the base 1. The two clamping plates 361 clamp the third guide wheel 33 and the fourth guide wheel 34. The two sliding parts are spaced apart along the height direction of the base 1. When the two first sliding parts 35 and the second sliding part 36 are connected, the two first sliding parts 35 approach each other along the height direction of the base 1, and then clamp the two clamping plates 361 together, thereby completing the installation of the third guide wheel 33 and the fourth guide wheel 34.

[0051] In this way, in actual production, a screw can be used to connect the large end of the screw to one of the first sliding parts 35, and the threaded end of the screw can pass through the two clamping plates 361 at once and then connect to the other first sliding part 35, thereby simplifying the installation steps of the sliding part 3 and facilitating the installation of the sliding part 3.

[0052] In some implementations, refer to Figures 5-7The first sliding part 35 includes two clamping blocks 351. The first sliding part 35 is connected to the first guide wheel 31 or the second guide wheel 32 through the two clamping blocks 351. The clamping direction of the two clamping blocks 351 is along the width direction of the base 1.

[0053] Furthermore, refer to Figure 5 The mounting cavity 11 includes a first inner wall 111, a second inner wall 112, a third inner wall 113 and a fourth inner wall 114. The first inner wall 111 and the second inner wall 112 are arranged in parallel opposite directions, and the third inner wall 113 and the fourth inner wall 114 are arranged in parallel opposite directions. The normal of the first inner wall 111 is along a first direction, and the normal of the third inner wall 113 is along a second direction.

[0054] With this arrangement, the first inner wall 111, the second inner wall 112, the third inner wall 113 and the fourth inner wall 114 form an enclosure around the sliding member 3, which enables the sliding member 3 to be stably limited in the first direction and the second direction.

[0055] Furthermore, refer to Figure 5 The base 1 includes a first bent plate 12 and a second bent plate 13 connected to each other. A first inner wall 111 and a third inner wall 113 are disposed on the first bent plate 12, and a second inner wall 112 and a fourth inner wall 114 are disposed on the second bent plate 13. The first bent plate 12 includes a first bent edge 121 and a second bent edge 122, and the first inner wall 111 and the third inner wall 113 are respectively disposed on the first bent edge 121 and the second bent edge 122. The second bent plate 13 includes a third bent edge 131 and a fourth bent edge 132, and the second inner wall 112 and the fourth inner wall 114 are respectively disposed on the third bent edge 131 and the fourth bent edge 132.

[0056] With this setup, the mounting cavity 11 can be formed when the bending angles of the first bending plate 12 and the second bending plate 13 are opposite each other. The installation of the base 1 can be completed by connecting the first bending edge 121 and the third bending edge 131, and connecting the second bending edge 122 and the fourth bending edge 132, which facilitates the installation of the base 1.

[0057] Furthermore, refer to Figure 1 and Figure 5 An installation gap 7 is provided between the first inner wall 111 and the fourth inner wall 114, that is, an installation gap 7 is provided between the first bent edge 121 and the third bent edge 131. The first inner wall 111 moves closer to or further away from the fourth inner wall 114 along a first direction. The distance indicator 6 includes a connector, one end of which is connected to the sliding member 3, and the other end of which extends out of the base 1 through the installation gap 7.

[0058] With this configuration, the installation gap 7 facilitates adjustment of the distance between the first inner wall 111 and the fourth inner wall 114, allowing the first guide wheel 31 and the second guide wheel 32 to respectively conform to the first inner wall 111 and the second inner wall 112. Simultaneously, the installation gap 7 facilitates the connection of the connecting member and the sliding member 3, allowing them to extend out of the base 1. Therefore, the installation gap 7 not only facilitates adjustment of the distance between the first inner wall 111 and the fourth inner wall 114 but also facilitates the connection between the connecting member and the sliding member 3.

[0059] Furthermore, refer to Figure 1 , Figure 5 The first bent plate 12 is provided with a fixing member 8. One end of the fixing member 8 is connected to the first bent plate 12, and the other end passes through the installation gap 7 and is connected to the second bent plate 13. Specifically, one end of the fixing member 8 is connected to the first bent edge 121, and the other end is connected to the third bent edge 131. Through this arrangement, the fixing member 8 achieves the connection between the first bent edge 121 and the third bent edge 131. At the same time, when the second mating part 4 slides away from the first mating part 2 via the sliding part 3, the fixing member 8 can limit the connection, thereby preventing the sliding part 3 from slipping off the base 1.

[0060] Similarly, the second bent edge 122 and the fourth bent edge 132 can also be connected using a fastener 8. In some embodiments, the fastener 8 can be a screw.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
