Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a coordinate measuring tool for detecting sensor positioning seats. Background Technology
[0002] In production such as Figure 1 When testing the sensor positioning seat 01 shown, its flatness and positional accuracy need to be checked to ensure that the geometric tolerances, such as flatness and positional accuracy, of the sensor positioning seat 01 meet the design requirements. However, production inspection personnel cannot directly use existing coordinate measuring machines to test the sensor positioning seat 01, resulting in slow inspection speed and low inspection efficiency. Utility Model Content
[0003] To improve the detection efficiency of side sensor positioning seats, this utility model proposes a coordinate measuring tool for detecting sensor positioning seats. The coordinate measuring tool for detecting sensor positioning seats includes a base, and a positioning mechanism is provided on the top plane of the base. The number and relative position of the positioning mechanism correspond to the clamping feet of the sensor positioning seat to be detected.
[0004] The positioning mechanism includes a detection pin and a positioning lock. The detection pin is installed and fixed on the top plane of the base, and the diameter of the detection pin is equal to the inner diameter of the positioning through hole on the locking foot of the sensor to be tested.
[0005] The positioning lock includes a locking pin and a locking block. The locking pin is installed and fixed on the top plane of the base and close to the detection pin, and the locking block is sleeved on the locking pin.
[0006] When using the coordinate measuring tool for sensor positioning seat testing of this invention to test the sensor positioning seat, simply place the sensor positioning seat on the base. The alignment of the positioning holes on the sensor positioning seat's feet with the detection pins in the positioning mechanism will determine whether the flatness and positional accuracy of the sensor positioning seat meet the design requirements. Furthermore, when installing and fixing the sensor positioning seat onto the base, the locking block in the positioning lock can be used to press down on the sensor positioning seat's feet, preventing the sensor positioning seat from falling off the coordinate measuring tool during testing and affecting the testing process. Therefore, using the coordinate measuring tool for sensor positioning seat testing of this invention to test the flatness and positional accuracy of the sensor positioning seat is simple, convenient, fast, and efficient.
[0007] Preferably, a locking spring is fitted onto the locking pin, and the locking spring presses against the locking block. This way, when the locking block is used to press down on the locking foot of the sensor positioning seat to be tested, the locking spring can press against the locking block, preventing the locking block from shifting and becoming misaligned, thus preventing the locking foot from being unable to be pressed down and affecting the detection. Further, the locking block includes a horizontal plate and a vertical plate. The horizontal plate has a locking hole for the locking pin to pass through, and the vertical plate is located between the horizontal plate and the base, and is perpendicularly connected to the horizontal plate to form an L-shaped structure. This way, the vertical plate in the locking block, in cooperation with the locking foot, keeps the horizontal plate parallel to the top plane of the base. When using the locking block to press down on the locking foot of the sensor positioning seat to be tested, the operator only needs to rotate the locking block, making the operation simple and convenient. More preferably, the locking hole is a strip-shaped through hole. This way, during use, the operator can move the locking block as needed, i.e., adjust the position of the locking pin in the locking hole, to facilitate the locking block pressing down on the locking foot of the sensor positioning seat to be tested. Therefore, when assembling the coordinate gauge for sensor positioning seat detection of this utility model, the setting accuracy of the locking pin in the positioning lock relative to the detection pin can be reduced, and the assembly difficulty of the coordinate gauge for sensor positioning seat detection of this utility model can be reduced.
[0008] Preferably, the base is provided with weight-reducing holes, and the positioning mechanism is distributed around the weight-reducing holes. This effectively reduces the weight of the coordinate measuring machine used for sensor positioning seat testing, facilitating operator movement of the coordinate measuring machine as needed. Furthermore, a positioning slot for mounting a positioning block is provided at the edge of the weight-reducing holes, and a positioning protrusion is provided on the top of the positioning block. The cross-section of the positioning protrusion has the same shape and specifications as the cross-section of the positioning hole on the sensor positioning seat to be tested. Thus, when the sensor positioning seat to be tested is installed on the coordinate measuring machine used for sensor positioning seat testing, if the positioning protrusion on the positioning block can be directly inserted into the positioning hole on the sensor positioning seat to be tested, it can be determined that the flatness and contour of the sensor positioning seat to be tested meet the design requirements.
[0009] Preferably, the bottom of the positioning slot is provided with at least two positioning pins, and the positioning block is installed and fixed in the positioning slot by the positioning pins. This uses two positioning pins to position the positioning block in the positioning slot, preventing misalignment of the positioning block when installed on the base, which would affect detection. Further, the base is provided with positioning bolts, which are installed on the side wall of the positioning slot and connected to the positioning block. This positioning bolt on the base connects to the positioning block when it is installed in the positioning slot, fixing the positioning block in the slot, making assembly and fixing simple and convenient. More preferably, the engaging surface of the positioning block facing the positioning slot is an L-shaped surface. This allows the L-shaped engaging surface to be used for positioning the positioning block when it is installed in the positioning slot, improving the assembly efficiency of the coordinate measuring machine for sensor positioning base detection of this utility model.
[0010] Preferably, an extension arm is provided on the side wall of the base, which is positioned opposite to the positioning slot, and the free end of the extension arm extends away from the positioning slot. In this way, during testing, the extension arm can be clamped by a fixture to erect the coordinate measuring machine for testing the sensor positioning seat of this invention, thereby testing the form and position tolerances of the sensor positioning seat to be tested. This increases the testing items of the coordinate measuring machine for testing the sensor positioning seat of this invention and expands its applicable scope. Attached Figure Description

[0015] Below, in conjunction with Figures 2 to 4 This paper provides a detailed description of the coordinate measuring tool used for detecting the sensor positioning seat of this utility model.
[0016] like Figures 2 to 4As shown, the coordinate measuring tool for detecting the sensor positioning seat of this utility model includes a base 1. A positioning mechanism is provided on the top plane of the base 1 (not shown in the figure). The number and relative position of this positioning mechanism correspond to the locking feet 21 of the sensor positioning seat 2 to be tested. For example, when the sensor positioning seat 2 to be tested has three locking feet 21, and these three locking feet 21 are evenly distributed on the same circumference, then the base 1 is provided with three positioning mechanisms, and these three positioning mechanisms are evenly distributed on the same circumference. The positioning mechanism includes a detection pin 31 and a positioning lock 32. The detection pin 31 is installed and fixed on the top plane of the base 1, that is, the detection pin 31 is perpendicular to the top plane of the base 1, and the diameter of the detection pin 31 is equal to the inner diameter of the positioning through hole (not shown in the figure) on the locking foot 21 of the sensor positioning seat 2 to be tested. Thus, when the operator places the sensor positioning seat 2 to be tested onto the coordinate measuring machine for testing the sensor positioning seat of this utility model, if the detection pin 31 is directly inserted into the positioning through hole on the corresponding latch 21, it can be determined that the flatness and position of the sensor positioning seat 2 to be tested meet the design requirements; if the detection pin 31 cannot be directly inserted into the positioning through hole on the corresponding latch 21, it can be determined that the flatness and position of the sensor positioning seat 2 to be tested do not meet the design requirements. The positioning lock 32 includes a locking pin 321 and a locking block 322. The locking pin 321 is installed and fixed on the top plane of the base 1 and close to the detection pin 31, and the locking block 322 is sleeved on the locking pin 321. In this way, when the sensor positioning seat 2 to be tested is installed and fixed onto the base 1, the locking block 322 in the positioning lock 32 can be used to press down the latch 21 of the sensor positioning seat 2 to be tested, preventing the sensor positioning seat 2 to be tested from falling off the coordinate measuring machine for testing the sensor positioning seat of this utility model during the testing process, which would affect the testing. Preferably, a locking spring 323 is fitted onto the locking pin 321, and the locking spring 323 presses against the locking block 322. Thus, when the locking block 322 presses against the locking foot 21 of the sensor positioning seat 2 to be tested, the locking spring 323 can press against the locking block 322, preventing the locking block 322 from shifting and becoming misaligned, thus failing to press against the locking foot 21 and affecting the detection. Preferably, the locking block 322 includes a horizontal plate 3221 and a vertical plate 3222. The horizontal plate 3221 is provided with a locking hole 32211 for the locking pin 321 to pass through. The vertical plate 3222 is located between the horizontal plate 3221 and the base 1 and is vertically connected to the horizontal plate 3221 to form an L-shaped structure. In this way, the vertical plate 3222 in the locking block 322 cooperates with the locking foot 21 to keep the horizontal plate 3221 parallel to the top plane of the base 1. When using the locking block 322 to press down the locking foot 21 of the sensor positioning seat 2 to be tested, the operator only needs to rotate the locking block 322, which is simple and convenient. Preferably, the locking hole 32211 is a strip-shaped through hole.In this way, during use, the operator can move the locking block 322 as needed, that is, adjust the position of the locking pin 321 in the locking hole 32211, so that the locking block 322 can press the locking foot 21 of the sensor positioning seat 2 to be tested. Therefore, when assembling the coordinate gauge for testing the sensor positioning seat of this utility model, the setting accuracy of the locking pin 321 in the positioning lock 32 relative to the detection pin 31 can be reduced, and the assembly difficulty of the coordinate gauge for testing the sensor positioning seat of this utility model can be reduced.
[0017] like Figures 2 to 4As shown, the base 1 is provided with weight-reducing holes 11, and the positioning mechanism is distributed around the weight-reducing holes 11. Thus, by providing weight-reducing holes 11 on the base 1, the weight of the coordinate measuring machine used for sensor positioning seat testing of this utility model can be effectively reduced, making it convenient for operators to move the coordinate measuring machine as needed. Preferably, a positioning slot 12 for mounting the positioning block 4 is provided at the edge of the weight-reducing hole 11, and a positioning protrusion 41 is provided on the top of the positioning block 4, and the cross-section of the positioning protrusion 41 has the same shape and specifications as the cross-section of the positioning hole (not shown in the figure) on the sensor positioning seat 2 to be tested. Thus, when the sensor positioning seat 2 to be tested is installed on the coordinate measuring machine used for sensor positioning seat testing of this utility model, if the positioning protrusion 41 on the positioning block 4 can be directly inserted into the positioning hole on the sensor positioning seat 2 to be tested, it can be determined that the flatness and contour of the sensor positioning seat 2 to be tested meet the design requirements. Preferably, the bottom of the positioning slot 12 is provided with at least two positioning pins 13, and the positioning block is installed and fixed in the positioning slot 12 by the positioning pins 13. In this way, using the two positioning pins 13 to position the positioning block 4 in the positioning slot 11 can prevent the positioning block 4 from being misaligned when installed on the base 1, thus affecting the detection. Preferably, the base 1 is provided with a positioning bolt 14, which is installed on the side wall of the positioning slot 11 and connected to the positioning block 4. Thus, providing a positioning bolt 14 on the base 1 to connect with the positioning block 4 when it is installed in the positioning slot 11, fixing the positioning block 4 in the positioning slot 11, makes assembly and fixing simple and convenient. Preferably, the engaging surface (not shown in the figure) of the positioning block 4 facing the positioning slot 11 is an L-shaped surface. Thus, when installing the positioning block 4 into the positioning slot 11, the L-shaped engaging surface can be used to position the positioning block 4, improving the assembly efficiency of the coordinate gauge for sensor positioning seat detection of this utility model. Preferably, an extension arm 15 is provided on the side wall of the base 1. The extension arm 15 is arranged opposite to the positioning slot 11, and the free end of the extension arm 15 extends away from the positioning slot 11. Thus, during testing, a clamp such as pliers can be used to hold the extension arm 15 to erect the coordinate measuring machine for testing the sensor positioning seat of this invention, so as to test the form and position tolerances of the sensor positioning seat 2 under test, increasing the testing items of the coordinate measuring machine for testing the sensor positioning seat of this invention and expanding its applicable scope. Preferably, all corners of the base 1 are rounded. This prevents operators from being cut by the sharp edges of the base 1 during use, improving the safety of using the coordinate measuring machine for testing the sensor positioning seat of this invention. Preferably, the base 1 is made of stainless steel to prevent rust and deformation.
[0018] In summary, the coordinate measuring tool for detecting sensor positioning seats of this invention is simple, convenient, fast, efficient, and safe when used to detect the flatness and position of the sensor positioning seat to be tested.
