[0002] The motor frame is an important part of the motor, mainly used to support and protect the various components inside the motor. The detection of the frame diameter is one of the key steps to ensure the correct installation and operation of the motor. The correct diameter size can ensure the good coordination between the motor and other mechanical components, as well as the stability and safety of the overall structure.

[0003] When measuring, the flat probes at both ends of the outside micrometer need to be kept in contact with the outer circle of the workpiece and moved back and forth to find the maximum point position of the outer circle of the workpiece to reduce the measurement error. In particular, finding the two-point position of the outer diameter is time-consuming, resulting in low measurement efficiency, and occasionally measurement position deviations will occur, leading to measurement errors. Summary of the invention

[0004] The present invention aims to solve the problem that it takes a long time to find the two-point position of the outer diameter of the workpiece in the prior art, and the measurement efficiency is low, and proposes the following technical solution:

[0006] After the moving jaw of the vernier caliper is adjusted, the detection component of the fixed block is fitted to the surface of the motor base, and the vernier caliper is pushed to make the detection component of the sliding block slide over the surface of the workpiece to be measured. The maximum or minimum data is read through the micrometer to obtain the outer diameter or inner diameter value of the motor base.

[0007] As a preferred embodiment of the above technical solution, the detection assembly includes a mounting block and an adjusting ring. The adjusting ring is threadedly sleeved on the surface of the mounting block. A replacement block is rotatably inserted in the middle of the mounting block. One end of the replacement block is flush with the surface of the adjusting ring. The adjusting ring is rotated to move relative to the mounting block, and the replacement block replaces the adjusting ring and fits the detection position of the motor base.

[0008] As a preferred embodiment of the above technical solution, a leveling sheet is sleeved on the surface of the replacement block, one end of the leveling sheet is in contact with the surface of the installation block, and the other end of the leveling sheet is flush with the surface of the adjustment ring.

[0009] As a preferred embodiment of the above technical solution, magnetic blocks are arranged inside the leveling plate and the mounting block, and the two magnetic blocks have opposite magnetic properties.

[0010] As a preferred embodiment of the above technical solution, the fixed block is installed on the front jaw of the vernier caliper through a locking screw, and the fixed block is installed on the upper and lower front jaws of the vernier caliper to respectively detect the inner diameter and outer diameter data of the motor base.

[0011] As a preferred embodiment of the above technical solution, the fixed block sliding block locking screw fixed block is installed on the front jaw of the vernier caliper, and the sliding block is installed on the upper and lower moving jaws of the vernier caliper to respectively detect the inner diameter and outer diameter data of the motor base.

[0012] The detection method of the motor base diameter detection device comprises the following steps:

[0013] S1, pre-adjustment;

[0014] Push the moving claw to move the sliding block so that the corresponding detection component moves, calculate the distance between the two detection components and set it as the basic distance;

[0015] S2, diameter detection;

[0016] After fitting the detection component corresponding to the fixed block to the surface of the workpiece to be measured, push the vernier caliper to make the detection component of the sliding block slide over the inner diameter or outer diameter surface of the workpiece to be measured, and record the maximum or minimum data read by the micrometer;

[0017] S3, data calculation;

[0018] When inspecting the inner diameter of a workpiece, the shrinkage distance data of the inspection component being pushed and retracted is recorded, and the inner diameter data of the workpiece is obtained by subtracting the shrinkage distance from the base distance;

[0019] When detecting the outer diameter of the workpiece, the expansion distance data of the detection component being pushed and expanded is recorded, and the base distance is added to the expansion distance to obtain the outer diameter data of the workpiece;

[0020] S4, data statistics;

[0021] The measured workpiece inner and outer diameter data are summarized and analyzed to identify potential problems and deficiencies in production.

[0022] The beneficial effects of the present invention are:

[0023] 1. Use a vernier caliper as the basic framework, combine the solid detection component with the micrometer, pre-adjust the position of the measuring movable jaw, push the vernier caliper to make the detection component of the sliding block slide across the surface of the workpiece to be measured, and use the contraction or expansion data of the detection component to quickly measure the outer diameter or inner diameter of the workpiece to be measured, which reduces the detection time and greatly improves the detection efficiency of the motor base;

[0024] 2. By adjusting the detection component to change its use shape, the basic detection points of the detection component are not changed.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings of the specification.

[0031] Example

[0032] Figure 1-Figure 4 In the present invention, the motor base diameter detection device comprises: a vernier caliper 10, a fixed block 20 and a sliding block, wherein one side of the fixed block 20 and the sliding block are both provided with a detection component 30, and the other end of the sliding block is provided with a micrometer 60 connected to the corresponding detection component 30;

[0033] After the moving jaws of the vernier caliper 10 are adjusted, the detection component 30 of the fixed block 20 is fitted onto the surface of the motor base, and the vernier caliper 10 is pushed so that the detection component 30 of the sliding block slides over the surface of the workpiece to be measured, and the maximum or minimum data is read through the micrometer 60 to obtain the outer diameter or inner diameter value of the motor base.

[0034] A vernier caliper 10 is used as the basic framework, and the solid detection component 30 and the micrometer 60 are combined together. After pre-adjusting the position of the measuring movable jaw, the vernier caliper 10 is pushed to make the detection component 30 of the sliding block slide across the surface of the workpiece to be measured, and the contraction or expansion data of the detection component 30 is used to quickly measure the outer diameter or inner diameter of the workpiece to be measured, thereby reducing the detection time and greatly improving the detection efficiency of the motor base.

[0035] The detection method of the motor base diameter detection device comprises the following steps:

[0036] S1, pre-adjustment;

[0037] Push the movable claw to move the sliding block so that the corresponding detection component 30 moves, calculate the distance between the two detection components 30 and set it as the basic distance;

[0038] S2, diameter detection;

[0039] After the detection assembly 30 corresponding to the fixed block 20 is attached to the surface of the workpiece to be measured, the vernier caliper 10 is pushed so that the detection assembly 30 of the sliding block slides over the inner diameter or outer diameter surface of the workpiece to be measured, and the maximum or minimum data read by the micrometer 60 is recorded;

[0040] S3, data calculation;

[0041] When detecting the inner diameter of the workpiece, the shrinkage distance data of the detection component 30 being pushed and retracted is recorded, and the inner diameter data of the workpiece is obtained by subtracting the shrinkage distance from the base distance;

[0042] When detecting the outer diameter of the workpiece, the expansion distance data of the detection component 30 being pushed and expanded is recorded, and the base distance is added to the expansion distance to obtain the outer diameter data of the workpiece;

[0043] S4, data statistics;

[0044] The measured workpiece inner and outer diameter data are summarized and analyzed to identify potential problems and deficiencies in production.

[0045] Figure 2-Figure 4 In the figure, the detection component 30 includes a mounting block 31 and an adjusting ring 32. The adjusting ring 32 is threadedly sleeved on the surface of the mounting block 31. A replacement block 33 is rotatably inserted in the middle of the mounting block 31. One end of the replacement block 33 is flush with the surface of the adjusting ring 32. The adjusting ring 32 is rotated to move relative to the mounting block 31, and the replacement block 33 replaces the adjusting ring 32 and fits the detection position of the motor base.

[0046] When inspecting the inner diameter of the motor base, the adjusting ring 32 is rotated to move it relative to the mounting block 31, and the replacement block 33 is exposed. The replacement block 33 can replace the adjusting ring 32 and fit the inspection position of the workpiece to be inspected, thereby preventing the inspection component 30 and the inspection position of the workpiece to be inspected from being suspended in the air and failing to perform inspection normally.

[0047] By adjusting the detection component 30 to change its use shape, the basic detection points of the detection component 30 are not changed. The adjustment method is simple and efficient, can adapt to the detection of the outer diameter and inner diameter of the workpiece to be measured, and is more convenient to use.

[0048] Figure 2-Figure 3In the embodiment, a leveling piece 34 is sleeved on the surface of the replacement block 33 , one end of the leveling piece 34 is in contact with the surface of the mounting block 31 , and the other end of the leveling piece 34 is flush with the surface of the adjustment ring 32 .

[0049] The leveling piece 34 and the mounting block 31 are both provided with magnetic blocks inside, and the two magnetic blocks have opposite magnetic properties.

[0050] The leveling piece 34 can block the position of the replacement block 33 to ensure the detection plane of the detection component 30, and avoid the situation where part of the workpiece enters the groove when detecting the outer diameter of the workpiece, causing incorrect detection data, thereby ensuring the accuracy of the data.

[0051] Figure 1 In the figure, the fixed block 20 is a sliding block through a locking screw 40; the fixed block 20 is installed on the front claw of the vernier caliper 10, and the fixed block 20 is installed on the upper and lower front claws of the vernier caliper 10 to respectively detect the inner diameter and outer diameter data of the motor base.

[0052] The fixed block 20, the sliding block locking screw 40, and the sliding block 50 are installed on the front claw of the vernier caliper 10, and the sliding block is installed on the upper and lower moving claws of the vernier caliper 10 to respectively detect the inner diameter and outer diameter data of the motor base.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
