Description

Technical Field

[0001] This application relates to the technical field of vehicle window motor testing devices, and more specifically to a height detection mechanism for a motor housing bearing mounting base. Background Technology

[0002] A car window motor is a motor used for raising and lowering car windows. The car window motor includes a housing, which refers to the motor housing of this application.

[0003] There is a type of motor housing, such as Figure 1 As shown, the device includes a first cavity 90, and a second cavity 91 is located in the middle section of the first cavity 90. A bearing mounting seat 92 is provided within the second cavity 91. It should be noted that it is necessary to test the height between the top surface of the bearing mounting seat 92 and the bottom wall of the first cavity 90. Currently, when testing the distance between the top surface of the bearing mounting seat 92 and the bottom wall of the first cavity 90, the motor housing is fixed, and the measurement is done manually using measuring tools. Specifically, the distance from the opening of the first cavity 90 to its bottom wall is measured first, and then the distance from the opening of the first cavity 90 to the bearing mounting seat 92 is measured. The difference between the two measurements gives the height of the bearing mounting seat 92 above the bottom wall of the first cavity 90. However, manually measuring two locations results in low efficiency and a large measurement error.

[0004] Therefore, there is a need for a mechanized and more efficient mechanism for detecting the height of the motor housing bearing mounting base. Summary of the Invention

Both ends of the first reset elastic element are connected to the reset base and the synchronous shoulder, respectively. The distance between the end of the fixed cylinder and the end of the detection rod is constant. By moving the slide and bringing the fixed cylinder into contact with the bottom wall of the first cavity, the retraction dimension of the measuring scale body is obtained. The difference between this retraction dimension and the distance between the end of the fixed cylinder and the end of the detection rod is the height dimension of the protruding part of the bearing fixed base. Compared with the prior art, this method has the advantages of mechanization and higher detection efficiency.

[0011] In one or more embodiments of this application, one side of the clamping hole has a through groove, and each of the vertical portions has a bolt hole that extends from one side of the vertical portion to the other side of the vertical portion and passes through the through groove.

[0012] In one or more embodiments of this application, the measuring mechanism further includes a limiting seat located at one end of the base away from the measuring ruler. When the slide slides a predetermined distance toward the placement seat, the slide abuts against the limiting seat.

[0026] Schematic diagram of a motor housing bearing mounting height detection mechanism, for reference. Figures 2 to 3 According to a preferred embodiment of the present invention, a height detection mechanism for a bearing mounting seat 92 of a motor housing is provided for testing the height dimension of the bearing mounting seat 92 of the motor housing. The motor housing includes a first cavity 90, and a second cavity 91 is provided in the middle section of the first cavity 90. The bearing mounting seat 92 is disposed in the second cavity 91. More specifically, the mechanism is used to test the height dimension of the top surface of the bearing mounting seat 92 above the bottom wall of the first cavity 90. The height detection mechanism for the bearing mounting seat 92 of the motor housing includes a base 10 and a measuring mechanism 20.

[0027] Specifically, the base 10 includes a placement seat (not shown in the figure) for fixing the motor housing. The placement seat has a groove, and a clamping block is provided on one side of the groove. The clamping block is moved by an electric push rod. Before measurement, the measuring personnel first place the motor housing into the groove, and then activate the electric push rod to make the clamping block abut against the motor housing, so that the two sides of the motor housing abut against the clamping block and the side wall of the groove, respectively, thereby fixing the motor housing.

[0028] In addition, such as Figure 2As shown, the base 10 also has a base 101. The measuring mechanism 20 includes a slide 201, a measuring scale 202, a reset seat 203, a fixed cylinder 204, a detection rod 205, and a first reset elastic element 206. The slide 201 is slidably disposed on the base 101. The fixed cylinder 204 and the measuring scale 202 are both connected to the slide 201 and located at both ends of the slide 201. The reset seat 203 is located between the fixed cylinder 204 and the measuring scale 202 and is connected to the slide 201. The measuring scale 202 passes through the reset seat 203. One end of the detection rod 205 extends into the reset seat 203 and abuts against the measuring scale 202. The other end of the detection rod 205 passes through the fixing cylinder 204. The end of the detection rod 205 extending into the reset seat 203 has a synchronous shoulder 2051, which abuts against the fixing cylinder 204. The two ends of the first reset elastic member 206 are respectively connected to the reset seat 203 and the synchronous shoulder 2051.

[0029] It should be noted that after the motor housing is placed on the mounting base, the detection rod 205 is directly opposite the bearing mounting base 92, and the fixing cylinder 204 is directly opposite the first recess 90. Before pressing the motor housing with the clamping block, the bearing mounting base 92 and one end of the detection rod 205 passing through the fixing cylinder 204 are first brought into contact, and the fixing cylinder 204 is extended into the first recess 90. Then, the motor housing is fixed by the action of the electric push rod; then the test is performed. Specifically, the slide block 201 is moved towards the placement seat. Since both the fixed cylinder 204 and the measuring scale 202 are mounted on the placement seat, when the placement seat moves, the fixed cylinder 204 and the measuring scale 202 move accordingly, causing the fixed cylinder 204 to abut against the bottom wall of the first recess 90. It should be noted that at this time, since one end of the detection rod 205 abuts against the bearing fixing seat 92, and the detection rod 205 passes through the fixed cylinder 204, and the detection rod 205 and the fixed cylinder 204 can slide relative to each other, when the fixed cylinder 204 abuts against the bottom wall of the first recess 90, the detection rod 205 itself does not move. However, since the measuring scale 202 moves with the slide block 201, and the detection rod 205 and the measuring scale 202 move together, the detection rod 205 abuts against the bottom wall of the first recess 90. When the measuring scale 202 contacts the measuring scale 202, the measuring scale 202 retracts into the housing of the measuring scale 202 a predetermined distance. This retraction distance is the moving distance of the slide 201, which is the distance from the end of the fixed cylinder 204 to the bottom wall of the first cavity 90. After measuring this data, it is subtracted from the distance between the end of the fixed cylinder 204 and the end of the measuring scale 202 in the initial state to calculate the height of the bearing fixing seat 92 above the bottom wall of the first cavity 90. It should also be noted that, because the synchronous shoulder 2051 is always abutting against one end face of the fixed cylinder 204 under the elastic force of the first reset elastic member 206, the distance between the end of the fixed cylinder 204 and the end of the measuring scale 202 in the initial state is a constant set value. Furthermore, after the test, when the slide block 201 slides away from the placement seat, both the fixed cylinder 204 and the detection rod 205 are reset to their initial positions under the elastic force of the first reset elastic element 206, which is preferably a spring. It is evident that, compared to the prior art, this application has the advantages of mechanization and higher detection efficiency.

[0030] Furthermore, to enable the fixed cylinder 204 and the reset seat 203 to be mounted on the slide 201, as follows: Figure 2 As shown, the slide 201 has two vertical parts 2011 at both ends, and each vertical part 2011 has a clamping hole 2012. One clamping hole 2012 clamps the fixing cylinder 204, and the other clamping hole 2012 clamps the reset seat 203.

[0031] In addition, to achieve clamping of the fixed cylinder 204 and the reset seat 203, such as Figure 2 and Figure 3 As shown, one side of the clamping hole 2012 has a through groove 2013, and each of the vertical portions 2011 has a bolt hole 2014. The bolt hole 2014 extends from one side of the vertical portion 2011 to the other side of the vertical portion 2011 and passes through the through groove 2013.

[0032] It should be noted that by inserting the fixed cylinder 204 and the reset seat 203 into the corresponding clamping hole 2012, and by tightening the bolt in the bolt hole 2014, the vertical parts 2011 on both sides of the through groove 2013 are brought closer to each other and clamp the fixed cylinder 204 or the reset seat 203.

[0033] Furthermore, to enable the slide block 201 to slide on the base 101, as follows: Figure 3 As shown, a slide rail 1011 is fixedly installed on the base 101, and the slide block 201 is slidably disposed on the slide rail 1011.

[0034] Furthermore, to prevent the slide block 201 from dislodging from the slide rail 1011, such as... Figure 3 As shown, the measuring mechanism 20 also includes a limiting seat 207, which is located at the end of the base 101 away from the measuring ruler 202. When the slide 201 slides a predetermined distance toward the placement seat, the slide 201 abuts against the limiting seat 207.

[0035] Furthermore, to achieve the power drive of the slide 201, such as Figure 3 As shown, the measuring mechanism 20 also includes a linear drive device 208, which is fixedly mounted on the base 101. The push rod of the linear drive device 208 is fixedly connected to the slide block 201, and the fixed connection method includes, but is not limited to, welding.

[0036] Furthermore, to specifically implement the installation of the measuring ruler 202 on the slide block 201, as follows: Figure 3 As shown, the slide 201 has an extension 2015 at one end away from the placement seat. The measuring ruler 202 is fixedly mounted on the extension 2015, and the extension 2015 is connected to the push rod of the linear drive device 208. The ruler housing of the measuring ruler 202 is bolted to the extension 2015.

[0037] Furthermore, to improve versatility, such as Figure 3As shown, the vertical part 2011 and the slide block 201 are detachably connected by bolts.

[0038] In summary, the height detection mechanism for the motor housing bearing mounting base described in the embodiments of this application is explained, which provides advantages such as mechanization and higher detection efficiency for the height detection mechanism of the motor housing bearing mounting base.

The purpose of the present invention has been fully and effectively achieved.
