Interpretation definitions: the stator module outer diameter measuring device defines the upper and lower directions of each component in the stator module outer diameter measuring device in a normal operation state.

Based on the references in this background: the problem that the outer diameter measurement value of the stator module is not accurate and the measurement efficiency is low in the prior art is that a stator module outer diameter measurement device is designed for measuring the outer diameter of the stator module 1.

As shown in fig. 1, in general, the stator module 1 formed by the block stator block group circle is in a hollow state. Referring to fig. 1, the stator module outer diameter measuring apparatus of the present application includes a fixing base 20, a conveying mechanism 3, a measuring mechanism 4, and a control mechanism (not shown temporarily).

Specifically, the fixing base 20 is mounted with the stator module 1. It can be seen that the holder 20 is provided with a mounting location (not shown) which is adapted to one end of the stator module 1.

Specifically, the conveying mechanism 3 has a first position 301 and a second position 302. The transport mechanism 3 transports the holder 20 back and forth between a first position 301 and a second position 302. It will be understood that the first position 301 of the transport mechanism 3 is the loading and unloading position (i.e. the position in which the stator module 1 is located in fig. 1), and the second position 302 of the transport mechanism 3 is the measuring position.

Further, referring to fig. 2 to 4, in order to accurately measure the outer diameter of the stator module, the measuring mechanism 4 includes a plurality of detecting joints 40 and a plurality of first transmission assemblies 42. The inspection sub 40 and the first transmission assembly 42 are provided in one-to-one correspondence, and the inspection sub 40 and the conveying path of the conveying mechanism 3 are mutually retracted to prevent the conveying mechanism 3 and the inspection sub 40 from interfering. Also, the sensing connections 40 are circumferentially disposed about the centerline of the second location 302.

Specifically, when the conveying mechanism 3 conveys the fixed seat 20 to the position corresponding to the measuring mechanism 4 (i.e. the second position 302 in the above description), at this time, the center of the second position 302 can be regarded as the center of the fixed seat 20, and errors existing in actual production and regulation are not described for the moment. The detection joint 40 is located in the circumferential direction of the fixing base 20, and the detection joint 40 is disposed toward the circumferential side wall of the stator module 1. Preferably, the detection joint 40 is arranged to extend in a radial direction of the stator module 1, i.e. in a direction perpendicular to the radial extension of the stator module 1 or the holder 20.

Further, the stator module 1 and the fixing base 20 are coaxially arranged, and the output end of the first transmission assembly 42 is in driving connection with the detection joint 40. The first transmission assembly 42 drives the detection joints 40 to move along the radial direction of the fixing base 20, so that each detection joint 40 is abutted to the circumferential side wall of the stator module 1 and then separated from the stator module 1.

Due to machining errors, the radial cross section of the stator module 1 is irregular and round (the measuring device in this application takes the cylindrical stator module as an example, and certainly is not limited to stator modules with other cross-sectional shapes, such as rectangular shape, etc.). But in the production process, partial errors can be allowed as long as the assembly and the performance of the product are not influenced.

In the present application, the amount of movement of the test sub 40 is calibrated to a predetermined value prior to measurement. The first transmission assembly 42 drives the detection joints 40 to move along the radial direction of the stator module 1 (the fixed seat 20) under the control of the control mechanism until each detection joint 40 abuts against the circumferential side wall of the stator module 1; at this time, the control mechanism obtains an actual moving value, and the control mechanism compares and analyzes the actual moving value and the predetermined value to obtain the outer diameter size of the stator module 1 (it can be known that when the detecting joints 40 are sufficient, a more accurate value can be obtained when the detecting joints 40 are arranged around the whole circumferential side of the stator module 1), and if the outer diameter size is within the allowable error range, the stator module 1 is good.

After the measurement is completed, the detection joint 40 is retracted and the transport mechanism 3 is moved along the transport path to transport the fixing base 20, together with the stator module 1, back to the first position 301 of the transport mechanism 3. The device has avoided manual measurement to produce measuring error, has promoted the uniformity of measurement mode, and the measuring accuracy is higher, has further promoted production efficiency.

Wherein, the conveying mechanism 3, the detection joint 40 and the first transmission component 42 are respectively and electrically connected with the control mechanism.

A first embodiment of the present application will now be explained in detail.

In one embodiment, referring to fig. 1 to 3, the first transmission assembly 42 includes a first guide rail 420 and a first power source 421, and the first power source 421 is drivingly connected to the detection joint 40. Alternatively, in the present application, the first power source 421 may be a cylinder.

Optionally, the apparatus further comprises a second support plate 500, the measuring mechanism 4 is mounted to the second support plate 500, and correspondingly, the first guide rail 420 and the first power source 421 are mounted to the second support plate 500.

Specifically, with continued reference to fig. 1 and 2, the first guiding rail 420 extends along a radial direction with the center of the second position 302 as a center. Further, the detection joint 40 is installed on the first guide rail 420, the first power source 421 is electrically connected to the control mechanism, and the control mechanism controls the first power source 421 to drive the detection joint 40, so that the detection joint 40 can move along the extending direction of the first guide rail 420 toward the direction close to the stator module 1 until the detection joint 40 abuts against the circumferential side wall of the stator module 1, and the control mechanism controls the first power source 421 to stop operating.

In one embodiment, with continued reference to fig. 3 and 4, the measuring mechanism 4 further includes a switch assembly 45, the switch assembly 45 includes a first switch 451 and a limiting portion 452 disposed opposite to each other, and one end of the first switch 451 is drivingly connected to the output end of the first power source 421.

Further, the position-limiting portions 452 are circumferentially spaced around the center of the second position 302, and the position-limiting portions 452 and the first switches 451 are arranged in a one-to-one correspondence.

When the detection joint 40 and the first switch 451 move along the extending direction of the first guide rail 420 and toward the direction close to the stator module 1 until the first switch 451 abuts against the limiting portion 452, that is, the switch assembly 45 is triggered to be turned off, the first switch 451 controls the first power source 421 to stop moving through the control mechanism. The switch assembly 45 is beneficial to reducing the motion error of the first power source 421, so that the moving distance of the detection joint 40 is more accurate.

In one embodiment, referring to fig. 3 and 4, the measuring mechanism 4 further includes a first elastic member 41, and two ends of the first elastic member 41 are respectively connected to the output ends of the detecting joint 40 and the first power source 421. Preferably, the first elastic member 41 is a member or assembly having expansion and contraction along its extending direction, such as a spring, silicon, rubber, etc.

Specifically, in order to protect each detection joint 40, the first elastic member 41 may provide a buffer space for the detection joint 40, and when the first power source 421 stops, the first elastic member 41 may drive the detection joint 40 to contract along the central axis direction thereof, so as to ensure that each detection joint 40 can be abutted to the peripheral side of the stator module 1. Meanwhile, the problem that the partial detection joints 40 are damaged due to too large abutting force after the position between each detection joint 40 and the fixed seat 20 deviates and has errors is solved.

In one embodiment, referring to fig. 1 to fig. 3, the stator module outer diameter measuring device further includes an abutting assembly 5, and the abutting assembly 5 includes a ball 501, a first push rod 50 and a second transmission assembly 51.

And the output end of the second transmission assembly 51 is in driving connection with the other end of the first push rod 50.

In one embodiment, the conveying mechanism 3 includes a second guide rail 32 and a third power source 33, the second guide rail 32 extends along a conveying path of the conveying mechanism 3, the second guide rail 32 is perpendicular to a central axis of the stator module 1, and the other end of the first support plate 31 is mounted on the second guide rail 32.

The working process of the device is as follows:

first, after the fixing base 20 and the stator module 1 move to the position (i.e., the second position 302) corresponding to the measuring mechanism 4, the second transmission assembly 51 drives the first push rod 50 to move a predetermined distance along the central axis direction of the stator module 1 through the control mechanism, that is, the ball 501 abuts against the top wall of the fixing base 20 so that the fixing base 20 and the second push rod 611 descend by a predetermined distance along the central axis direction of the fixing base 20.

Then, the detection joint 40 is pushed down by the first power source 421, and the first power source 421 stops working after the switch assembly 45 is triggered. At this time, the detection joint 40 abuts against the circumferential side wall of the stator module 1 under the urging of the first power source 421. Preferably, when the detection joint 40 is in contact with the stator module 1 for the first time, the detection joint 40 is in contact with the periphery of the position of the stator module 1 close to the bottom, and the control mechanism can obtain a set of actual movement values of the detection joint 40. Synchronously, after the detection joint 40 obtains the first set of actual values, the first power source 421 drives the detection joint 40 to move along the extending direction of the first guide rail 420 toward the direction away from the stator module 1, so that the detection joint 40 is separated from the circumferential side wall of the stator module 1, and interference between the detection joint 40 and the subsequent stator module 1 during rotation is avoided.

Alternatively, the two detection joints 40 are in a group, and the two detection joints 40 in the group are arranged oppositely, that is, the two detection joints 40 simultaneously abut against the circumferential outer wall of the stator module 1. It will be appreciated that, at this point, the actual movement values of the two opposing test connections 40 may be combined, and a set of outer diameter data for the stator module 1 may be obtained by calculation and fitting by the control mechanism.

Next, the third transmission assembly 60 drives the fixing base 20 to rotate along the central axis thereof (clockwise or counterclockwise) by a predetermined angle, such as 10 degrees, 20 degrees or 30 degrees, and then the detection joint 40 abuts against the peripheral side of the stator module 1 again to obtain a second set of actual movement values. For example: when the angle of rotation at every turn is 30 degrees, fixing base 20 need drive stator module and rotate 12 times along same direction to obtain the 12 actual numerical values that move of the same water flat height of group, can obtain the external diameter size of the stator module 1 that corresponds the water flat through control mechanism analysis and fitting with this numerical value.

In this way, the second transmission assembly 51 drives the first push rod 50 to continuously move the same predetermined distance along the central axis direction of the stator module 1 through the control mechanism, so that each detection joint 40 is located at another horizontal line height position (with respect to the axial direction of the stator module 1), and the above-mentioned rotating process, measuring process and analyzing process are repeated to obtain the outer diameter dimensions of different height positions of the circumferential side of the stator module 1. And finally, comprehensively comparing and analyzing the numerical values to judge whether the whole circumferential outer diameter of the stator module 1 is qualified.

It can be known that, in the present application, the process of analyzing and fitting the actual movement value by the control mechanism is known by a person skilled in the art through conventional technical means, and is not described in detail herein.

A second embodiment of the present application will now be explained in detail, which scheme is not illustrated for the time being.

In one embodiment, the stator module outer diameter measuring device further includes a rotating component, the rotating component includes a third transmission component 60, an output end of the third transmission component 60 is connected to the measuring mechanism 4, and the third transmission component 60 drives the measuring mechanism 4 to rotate by a predetermined angle along the central axis of the fixing base 20. That is, the third transmission assembly 60 drives the detection joint 40 to rotate along the central axis (clockwise or counterclockwise) of the stator module by a predetermined angle, such as 10 degrees, 20 degrees or 30 degrees, and then the detection joint 40 abuts toward the peripheral side of the stator module 1 again to obtain the actual movement value. And, during the rotation of the detection joint 40, the fixing base 20, together with the stator module 1, is in a relatively immovable state.
