Description

Technical Field

[0001] This invention relates to the field of wheel speed sensor manufacturing, and more particularly to an active wheel speed sensor probe height detection device. Background Technology

[0002] During the manufacturing process of wheel speed sensors, the height of their probes needs to be measured. Currently, there is no equipment on the market specifically for measuring the probe height of wheel speed sensors. Therefore, the probe height is mainly measured manually using calipers. This method is not only inefficient but also produces inaccurate data, only meeting the requirements for measurements with large tolerances, and failing to meet the needs for measurements with small tolerances. Summary of the Invention

[0003] The purpose of this invention is to provide an active wheel speed sensor probe height detection device, which solves the problem that the existing wheel speed sensor probe height is mainly detected manually using calipers. This method is not only inefficient, but also the caliper measurement data is not accurate enough. It can only meet some detection requirements with large tolerances, but cannot meet the detection requirements with small tolerances.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: an active wheel speed sensor probe height detection device, including a base plate, a product fixing plate with position adjustment on the base plate, and a right fixing plate located to the right of the product fixing plate; a positioning hole is opened on the product fixing plate, and a detachable product positioning block is provided on the side of the product fixing plate opposite to the right fixing plate, the product positioning block having a probe mounting hole adapted to the positioning hole; a dial indicator is provided on the right fixing plate, the measuring rod of the dial indicator is set along the X-axis direction; the head of the measuring rod of the dial indicator is positioned directly opposite the probe mounting hole; it also includes a height standard block that can be removed and placed, the height standard block including a fixed part and a column part, the fixed part and the side wall of the product positioning block opposite to the right fixing plate are adapted, the column part can be placed in the probe mounting hole, the column part and the probe mounting hole are clearance fitted, and the length of the column part is adapted to the standard height of the probe to be measured.

[0005] Furthermore, a left fixing plate is provided on the left side of the upper surface of the base plate, and a set of guide posts arranged along the X-axis is provided between the left fixing plate and the right fixing plate. Each guide post is provided with a linear guide sleeve, and the lower part of the product fixing plate is provided with a guide sleeve fitting hole that matches the linear guide sleeve. A limit block is also provided on the base plate. The limit block is arranged along the X-axis and has a strip hole extending along the X-axis. The lower part of the outer wall of the product fixing plate facing the limit block has a limit hole that matches the strip hole. A side locking bolt is provided between the strip hole and the limit hole.

[0006] Furthermore, the base plate is provided with a linear slide rail along the X-axis, and a slider with a locking function is provided on the linear slide rail. The bottom of the product fixing plate is set on the slider.

[0007] Furthermore, the upper part of the right fixed plate is provided with an assembly through hole that matches the dial indicator measuring rod, and the top end face of the right fixed plate is provided with an upper positioning through hole that communicates with the assembly through hole; the upper positioning through hole is provided with an upper locking bolt, and the bottom of the upper locking bolt is connected to the side wall of the dial indicator measuring rod.

[0008] Furthermore, a set of height standard blocks is provided, and the length of the standard height column of each standard height block is adapted to the length of the probe to be measured of different lengths.

[0009] The beneficial effects of this invention are as follows: 1. By setting up a dial indicator, a height standard block, an adjustable product fixing plate, and a product positioning block in coordination, the height of the probe to be tested can be quickly detected, and whether the height is qualified can be determined. This structure is simple and reliable, and can conveniently realize the detection of wheel speed sensor probe height. It effectively solves the problem that the existing wheel speed sensor probe height is mainly detected manually using calipers, which is not only inefficient, but also the caliper measurement data is not accurate enough, and can only meet some detection requirements with large allowable tolerances, but cannot meet the detection requirements with small allowable tolerances.

[0010] Guide posts, linear guide sleeves, limit blocks, limit holes, and side locking bolts enable stable and reliable movement of the product fixing plate, while also locking the product fixing plate in the required position.

[0011] Linear guide rails and sliders with locking functions provide a new option for the movement of product fixing plates, ensuring stable and reliable movement of the product fixing plates and enabling position locking.

[0012] A set of height standard blocks can meet the detection requirements of probes of different lengths, making the application range of this active wheel speed sensor probe height detection device wider and better able to meet market demands.

[0013] The product positioning block is detachable, and by replacing the product positioning block, it can be adapted to different sensor products, thereby increasing the applicability.

[0019] Examples, such as Figures 1 to 3 An active wheel speed sensor probe height detection device is shown, comprising a base plate 1, an adjustable product fixing plate 2 on the base plate 1, and a right fixing plate 3 located to the right of the product fixing plate 2. The product fixing plate 2 has a positioning hole 5, and a detachable product positioning block 6 is located on the side of the product fixing plate 2 opposite to the right fixing plate 3. The product positioning block 6 has a probe mounting hole 7 that matches the positioning hole 5. A dial indicator 8 is mounted on the right fixing plate 3, with its measuring rod 9 positioned along the X-axis. The head of the measuring rod 9 of the dial indicator 8 faces the probe mounting hole 7. The device also includes a removable height standard block, comprising a fixing part 10 and a column part 11. The fixing part 10 is fitted to the side wall of the product positioning block 6 opposite to the right fixing plate 3. The column part 11 can be placed inside the probe mounting hole 7 with a clearance fit. The length of the column part 11 matches the standard height of the probe to be measured. The product positioning block 6 and the product fixing plate 2 are fixedly connected by bolts. The measuring rod 9 of the column part 11 and the dial indicator 8 are adapted.

[0020] A left fixing plate 4 is provided on the left side of the upper end face of the base plate 1. A set of guide posts 12 arranged along the X-axis is provided between the left fixing plate 4 and the right fixing plate 3. Each guide post 12 is provided with a linear guide sleeve 13. The lower part of the product fixing plate 2 is provided with a guide sleeve fitting hole that matches the linear guide sleeve 13. A limit block 14 is also provided on the base plate 1. The limit block 14 is arranged along the X-axis. A strip hole 15 extending along the X-axis is opened on the limit block 14. A limit hole 16 matching the strip hole 15 is opened on the lower part of the outer wall of the product fixing plate 2 facing the limit block 14. A side locking bolt is provided between the strip hole 15 and the limit hole 16.

[0021] The base plate is provided with a linear slide rail along the X-axis. The linear slide rail is located on the left side of the right fixed plate 3. A slider with locking function is provided on the linear slide rail. The bottom of the product fixed plate 2 is set on the slider.

[0022] The upper part of the right fixed plate 3 is provided with an assembly through hole 17 that is compatible with the measuring rod 9 of the dial indicator 8. The top end face of the right fixed plate 3 is provided with an upper positioning through hole 18 that communicates with the assembly through hole 17. An upper locking bolt is provided in the upper positioning through hole 18, and the bottom of the upper locking bolt is connected to the side wall of the measuring rod 9 of the dial indicator 8.

[0023] A set of height standard blocks is provided, and the length of the standard height column of each standard height block is adapted to the length of the probe to be measured of different lengths.

[0024] Place the height standard block into the probe mounting hole 7. The cylindrical part 11 of the height standard block is located inside the probe mounting hole 7. The fixing part 10 and the side wall of the product positioning block 6 are in contact. The product fixing plate 2 moves so that the cylindrical part 11 and the head of the dial indicator 8 measuring rod 9 are in contact. The dial indicator 8 measuring rod 9 is retracted. The retraction length is greater than the tolerance range of the height of the probe to be measured specified in the drawing. The dial indicator 8 is zeroed and the position of the product fixing plate 2 is locked, completing the initial setting.

[0025] Then, remove the height standard block. The measuring rod 9 of dial indicator 8 will spring back, and the reading on dial indicator 8 will be negative. Install the probe to be tested into the probe mounting hole 7. If the height of the probe to be tested is exactly the same as the height standard block, the reading on dial indicator 8 should be 0. If they are not the same, the value read by dial indicator 8 is the positive or negative tolerance of the probe to be tested. Of course, if the negative deviation of the probe size is too large, and it cannot even make contact with dial indicator 8, and the reading on dial indicator 8 does not change, then it is directly judged as unqualified.
