Abstract
Description
Technical Field
[0001] The present application relates to a detection mechanism for a motor housing, belonging to the technical field of motor housing detection. Background Art
[0002] With the development of the economy and the continuous improvement of people's living standards, cars have become an important means of transportation for people. During the use of cars, their motors are the main core power. Therefore, it is very important and necessary to detect the housing of the drive motor for new energy vehicles.
[0003] During the processing of the motor housing, an upper stop and a lower stop need to be machined on the inner wall of the motor housing. Due to the wear of the cutting tool, there are differences in the inner diameter dimensions of the same batch of motor housings. If the inner diameter of the housing is too large, the iron core will fall off, and if the inner diameter of the housing is too small, the iron core will touch the housing, affecting the normal operation of the iron core.
[0004] Therefore, to solve the above technical problems, it is indeed necessary to provide a detection mechanism for a motor housing to detect the inner diameter of the motor housing and overcome the defects in the prior art. Summary of the Utility Model
[0005] The purpose of the present utility model is to provide a detection mechanism with high automation degree that can detect the inner diameter, upper stop, lower stop and height of the motor housing.
[0006] To achieve the above purpose, the technical solution adopted by the present utility model is: including a frame, and further including a base slidably connected to the frame and an upper elastic claw mechanism slidably connected to the frame. The sliding path of the upper elastic claw mechanism corresponds to the sliding path of the base. The frame is equipped with a turntable that rotates around the direction of movement of the upper elastic claw mechanism. The turntable is used to drive the motor housing to rotate, and the upper elastic claw mechanism is used to detect the inner diameter of the upper stop of the motor housing.
[0007] By adopting the above technical solution, the base can drive the motor housing to move towards the upper elastic claw mechanism. The upper elastic claw mechanism is used to detect the inner diameter of the upper stop of the motor housing to obtain the first data. By rotating the turntable to drive the motor housing to rotate, the adjusted motor housing enters the upper elastic claw mechanism again to obtain the second data of the inner diameter of the upper stop of the motor housing. The inner diameter of the upper stop is obtained by combining the first data and the second data.
[0008] The detection mechanism for a motor housing of the present utility model is further provided as: a through groove is provided on the base, and a lower elastic claw mechanism is slidably connected to the frame. The lower elastic claw mechanism can pass through the base and is used to detect the inner diameter of the lower stop of the motor housing.
[0009] A detection mechanism for a motor housing of the present utility model is further configured as follows: A plurality of positioning blocks are installed on the side wall of the through groove, and the plurality of positioning blocks can move away from or close to the center point of the through groove.
[0010] By adopting the above technical solution, the positioning blocks can fix the position of the motor housing and improve stability.
[0011] A detection mechanism for a motor housing of the present utility model is further configured as follows: The turntable moves up and down through a telescopic mechanism. The turntable can pass through the base, and the telescopic mechanism is installed on the frame.
[0012] By adopting the above technical solution, the turntable can jack up the motor housing, rotate automatically when jacking up to adjust the position of the motor housing. When the turntable drops, the motor housing is fixed by the positioning blocks. When the turntable descends below the base, it can avoid affecting the normal movement of the base. The turntable can automatically adjust the position of the motor housing, improving the automation level.
[0013] A detection mechanism for a motor housing of the present utility model is further configured as follows: It further includes a plug block probe mechanism. The plug block probe is slidably connected to the frame, and the sliding path of the plug block probe mechanism corresponds to the sliding path of the base.
[0014] By adopting the above technical solution, the plug block probe is used to measure the inner diameter of the motor housing. With the corresponding sliding paths, it can simultaneously detect the inner diameter of the motor housing and the inner diameter of the lower stop. The plug block probe can slide up and down to obtain the inner diameters at two positions in the vertical direction of the motor housing.
[0015] A detection mechanism for a motor housing of the present utility model is further configured as follows: The moving path of the plug block probe mechanism corresponds to the moving position of the lower elastic claw mechanism.
[0016] By adopting the above technical solution, the plug block probe mechanism and the elastic claw mechanism can simultaneously measure the motor housing, accelerating the measurement time.
[0017] A detection mechanism for a motor housing of the present utility model is further configured as follows: It further includes a height measurement mechanism. The height measurement mechanism is installed on the frame, and the height measurement mechanism is used to measure the height of the motor housing.
[0018] A detection mechanism for a motor housing of the present utility model is further configured as follows: When the upper elastic claw mechanism measures the inner diameter of the upper stop of the motor housing, the height measurement mechanism measures the height of the motor housing.

The two sensors I are located on both sides of the turntable. When the turntable drives the motor housing to move onto the base, the sensor I receives a signal.
[0020] The detection mechanism of a motor housing of the present utility model is further configured as follows: A second sensor is also installed on the frame, and the second sensor is located on both sides of the height detection mechanism. When the base drives the motor housing to move to the height detection mechanism, the second sensor receives a signal.

[0031] Please refer to the attached drawings in the specification Figure 1 to Figure 6As shown, the horizontal direction is a and the vertical direction is b. The present utility model is a detection mechanism for a motor housing. The motor housing 1 is in an elliptical cylindrical shape. An upper stop 11 is provided on the inner wall at the upper end of the motor housing 1, and a lower stop 12 is provided on the inner wall at the lower end of the motor housing 1. The detection mechanism includes a frame 2 and a base 21 that is horizontally slidably connected to the frame 2. The base 21 sequentially passes through a turntable 22 longitudinally installed on the frame 2, a lower elastic measuring claw mechanism 3, a plug measuring head 43 mechanism 4, an upper elastic measuring claw mechanism 5, and a height measuring mechanism 6. In this embodiment, the lower elastic measuring claw mechanism 3 corresponds to the plug measuring head 43 mechanism 4, and the upper elastic measuring claw mechanism 5 corresponds to the height measuring mechanism 6.
[0032] The turntable 22 moves up and down through a telescopic mechanism 221. The telescopic mechanism 221 is installed on the frame 2. In this embodiment, the turntable 22 is in a cross shape and includes two layers. The top layer of the turntable 22 has a size smaller than the inner diameter of the motor housing 1, and the bottom layer of the turntable 22 has a size larger than the inner diameter of the motor housing 1. When in use, the motor housing 1 can be sleeved on the turntable 22.
[0033] A through groove 23 for the up and down movement of the turntable 22 is provided on the base 21. The turntable 22 can pass through the base 21. A number of positioning blocks 231 are installed on the side wall of the through groove 23. The number of positioning blocks 231 can move away from or close to the center point of the through groove 23. When in use, the turntable 22 extends out of the base 21 through the through groove 23. The motor housing 1 is placed on the turntable 22, and the height of the turntable 22 is lowered until the motor housing 1 is installed on the turntable 22. The positioning blocks 231 are moved in a direction away from the center point of the through groove 23 until the motor housing 1 is fixed on the base 21. In this embodiment, the base 21 moves horizontally through a servo motor 211. Two sensors 222 are also installed on the frame 2. The two sensors 222 are located on both sides of the turntable 22. When the turntable 22 drives the motor housing 1 to move onto the base 21, the sensors 222 receive signals and start the positioning blocks 231 to clamp the motor housing 1, with a high degree of automation.
[0034] The lower elastic measuring claw mechanism 3 includes two lower inner diameter measuring heads 31. The lower inner diameter measuring heads 31 move horizontally on the frame 2 through lower horizontal cylinders 32. The two lower horizontal cylinders 32 are fixedly connected to a lower mounting plate 33. The lower mounting plate 33 is lifted and lowered through a first lower lifting cylinder 35. A lower abutting block 34 is fixedly connected to the lower mounting plate 33. An activity groove for the movement of the lower inner diameter measuring heads 31 is provided on the lower abutting block 34. The lower abutting block 34 is used to protect the lower inner diameter measuring heads 31 to prevent the lower inner diameter measuring heads 31 from being damaged when they rise and touch the motor housing 1. The lower inner diameter measuring heads 31 are used to measure the inner diameter of the lower stop 12 of the motor housing 1.
[0035] The plug block probe mechanism 4 includes a support plate 41 fixed to the top of the frame 2. A plug block probe 43 is slidably connected to the support plate 41. The plug block probe 43 is driven vertically by a plug block cylinder 42. An induction point (not shown in the figure) is installed at each end of the plug block probe 43. The two induction points are used to measure the inner diameter of the motor housing 1. The sliding path of the plug block probe 43 corresponds to the sliding path of the lower inner diameter probe 31, and can simultaneously detect the inner diameter of the motor housing 1 and the inner diameter of the lower stop 12. The plug block probe 43 can slide up and down to obtain the inner diameters at two places in the vertical direction of the motor housing 1, avoiding excessive inner diameter errors in the vertical direction of the motor housing 1.
[0036] The upper elastic measuring claw mechanism 5 includes two upper inner diameter probes 51. The upper inner diameter probes 51 move longitudinally on the frame 2 through upper longitudinal cylinders 52. The two upper longitudinal cylinders 52 are fixedly connected to an upper mounting plate 53. The upper mounting plate 53 is lifted and lowered by a first lifting cylinder 55. An upper abutting block 54 is fixedly connected to the upper mounting plate 53. An activity groove for the upper inner diameter probe 51 to move is provided on the upper abutting block 54. The upper abutting block 54 is used to protect the upper inner diameter probe 51 to avoid damage to the upper inner diameter probe 51 when it rises and touches the motor housing 1. The upper inner diameter probe 51 is used to measure the inner diameter of the upper stop 12 of the motor housing 1.
[0037] The height measuring mechanism 6 includes an upper dial gauge measuring block 61 and a lower dial gauge measuring block 62. The upper dial gauge measuring block 61 is lifted and lowered by an upper height cylinder 611, and the lower dial gauge measuring block 62 is lifted and lowered by a lower height cylinder 621. An inductor fixing piece 63 is installed below the upper dial gauge measuring block 61. In this embodiment, the inductor fixing piece 63 is arc-shaped. Sensors two 64 are installed at both ends of the inductor fixing piece 63. When the motor housing 1 moves towards the upper dial gauge measuring block 61, the sensors two 64 can sense the position of the motor housing 1 to avoid the motor housing 1 hitting the upper dial gauge measuring block 61 when it moves.
[0038] The working principle of the detection mechanism of the motor housing 1 of the utility model is as follows: first, the motor housing 1 is placed on the turntable 22, the height of the turntable 22 is lowered until the motor housing 1 is placed on the base 21, the positioning block 231 is started, and the positioning blocks 231 are moved away from the center of the through slot 23 until the motor housing 1 is fixed by the positioning blocks 231, the base 21 is moved, the motor housing 1 is moved downward to the elastic measuring claw mechanism 3, the lifting cylinder 1 is started, and the two lower inner diameter measuring heads 31 are linked to move to the lower stop 1 of the motor housing 1 2, start the lower horizontal cylinder 32, make the lower inner diameter probe 31 move to the side wall of the lower stop 12 of the motor housing 1, and obtain the inner diameter of the lower stop 12, move the plug probe 43 into the motor housing 1, and obtain the inner diameter of the motor housing 1 through the sensing point on the plug probe 43, and lift the plug probe 43 again to obtain another inner diameter of the motor housing 1 through the sensing point. After detecting the inner wall of the motor housing 1 and the inner diameter of the lower stop 12, move the base 21 to move the motor housing 1 to the upper elastic measuring claw mechanism 5, and start the lifting cylinder 2. , the two upper inner diameter measuring heads 51 are linked to move toward the side wall of the upper stop 11 of the motor, and the inner diameter of the upper stop 11 is obtained. The upper dial gauge measuring block 61 and the lower dial gauge measuring block 62 are moved to the motor housing 1 to measure the height of the motor housing 1. After detecting the height of the motor housing 1 and the inner diameter of the upper stop 11, the base 21 drives the motor housing 1 to move above the turntable 22, releases the connection between the positioning block 231 and the motor housing 1, raises the turntable 22, lifts the motor housing 1, rotates 90 degrees, and fixes the motor housing 1 again. On the base 21, the mobile base 21 detects the inner diameter, the lower stop 12, the upper stop 11 and the height of the inner wall of the motor housing 1 in turn to obtain a second set of data, and takes the average of the two sets of data and compares them with the standard size. If the value is within 0.06mm of the standard, production is carried out. Otherwise, the tool is readjusted to process a new motor housing 1 until the processing meets the standard motor housing 1. The motor housings 1 to be produced are inspected by the inspection mechanism in turn. If an unqualified motor housing 1 is found, the above-mentioned tool adjustment steps are repeated to realize the inspection of the motor housing 1.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
