Description

Technical Field

[0001] This invention relates to the field of motor parts technology, and in particular to a tooling for inspecting motor end caps. Background Technology

[0002] Four mounting holes on the motor end cover The positional accuracy (89.39±0.02) relative to the center of the bearing housing is a critical requirement; any deviation in position will affect the assembly performance between the motor and the end cover. Currently, this is calculated manually using vernier calipers.

[0003] The shortcomings of the above detection methods are:

[0004] 1. Measurement errors pose certain difficulties for product quality inspection, making it hard to reach consistent inspection results.

[0005] 2. Measuring with vernier calipers requires the inspector to have certain professional knowledge and work experience.

[0006] 3. The efficiency of the inspection is relatively low, and the proportion of samples taken is not high. Summary of the Invention

[0007] The technical problem solved by this invention is to provide a tooling for testing motor end caps.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] A motor end cover inspection fixture includes a limit assembly:

[0010] The limiting component is used for positioning and inserting the motor end cover;

[0011] A fixed-point detection component is connected to the top rear end of the limit component. The fixed-point detection component includes a vertical position adjustment component, a detection component, and a sensing component. The vertical position adjustment component is connected to the limit component. The driving end of the vertical position adjustment component is connected to the sensing component and the detection component. The detection component is located outside the sensing component. The vertical position adjustment component drives the sensing component and the detection component to move downward. The detection component contacts the motor end cover. When the sensing value of the sensing component gradually increases before the vertical position adjustment component moves to the set position, the motor end cover does not meet the standard. When the sensing value of the sensing component does not change when the vertical position adjustment component moves to the set position, the motor end cover meets the standard.

[0012] The vertical position adjustment component is connected to the lifting component. When the lifting component moves upward, it pushes the motor end cover inside the support platform upward.

[0013] Furthermore, the limiting component includes a support platform, a bearing housing insertion hole, and a motor cover insertion hole. The motor cover insertion hole is provided on the top of the support platform, and a bearing housing insertion hole is provided at the bottom of the motor cover insertion hole. The motor end cover is inserted into the motor cover insertion hole, and the bearing housing is inserted into the bearing housing insertion hole.

[0014] A movable plate is fixedly connected to the drive end.

[0015] Furthermore, the vertical position adjustment component includes a cylinder, a mounting plate, and a movable plate. The mounting plate is fixedly installed on the top of the support platform, and a cylinder is fixedly connected to the top of the mounting plate. The movable plate is fixedly connected to the cylinder drive end.

[0016] Furthermore, the detection assembly includes a protrusion, a slide bar, a mounting plate, a bearing housing detection block, and a mounting hole detection rod. The movable plate is slidably connected to the slide bar through a straight hole. A protrusion is fixedly connected to the top of the slide bar, and a mounting plate is fixedly connected to the bottom of the slide bar. Mounting hole detection rods are symmetrically fixedly connected to the bottom of the mounting plate, and a bearing housing detection block is fixedly connected to the bottom of the mounting plate.

[0017] Furthermore, the sensing component uses a pressure sensor, which is fixedly installed on the bottom of the movable plate, and the sensing end of the pressure sensor is fixedly connected to the mounting plate.

[0018] Furthermore, when the cylinder extension end extends downwards to half its length, the bearing housing detection block and the mounting hole detection rod are in the detection and positioning stage, and the distance between the bottom of the bearing housing detection block and the mounting hole detection rod and the support platform is twice the height of the motor end cover.

[0019] Furthermore, the lifting assembly includes a push rod, a push rod connecting plate, a connecting plate, a lifting hole, and a straight hole. The support platform has a straight hole, and a connecting plate is slidably connected inside the straight hole. The bottom of the connecting plate is fixedly connected to the push rod connecting plate, and push rods are symmetrically fixedly connected to the top of the push rod connecting plate. The bottom of the support platform has symmetrically opened lifting holes that cooperate with the push rods.

[0020] Furthermore, the top of the connecting plate is fixedly connected to the movable plate.

[0021] The specific beneficial effects are as follows:

[0022] In this invention, the vertical position adjustment component drives the sensing component and the detection component to move downwards. The detection component contacts the motor end cover. If the sensing value of the sensing component gradually increases before the vertical position adjustment component moves to the set position, the motor end cover does not meet the standard. If the sensing value of the sensing component does not change when the vertical position adjustment component moves to the set position, the motor end cover meets the standard. The measurement is error-free, and it can form a consistent inspection result for product quality inspection. It does not require high skills from inspectors, and the inspection method is easy to master. It can be used for large-scale inspection.

[0023] In this invention, the cylinder drives the movable plate to move upward to the detection and positioning stage, and then continues to move upward. The movable plate drives the connecting plate of the lifting assembly to move along the straight hole. The straight hole drives the push rod connecting plate to move, and the push rod connecting plate drives the push rod to move. The push rod moves upward in the lifting hole, and the lifting hole pushes the motor end cover in the motor cover insertion hole to lift upward, thereby separating the motor end cover from the limiting assembly.

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] Example 1

[0033] like Figure 1-6 As shown, a motor end cover inspection fixture includes a limiting component 1:

[0034] Limiting component 1 is used for positioning and plugging the motor end cover;

[0035] The limiting component 1 includes a support platform 11, a bearing housing insertion hole 12, and a motor cover insertion hole 13. The support platform 11 has a motor cover insertion hole 13 at the top and a bearing housing insertion hole 12 at the bottom of the motor cover insertion hole 13. The motor end cover is inserted into the motor cover insertion hole 13 and the bearing housing is inserted into the bearing housing insertion hole 12.

[0036] Manual or robotic arm inserts the motor end cover into the motor cover insertion hole 13 of the limiting component 1, and the bearing chamber into the bearing chamber insertion hole 12. The bearing chamber insertion hole 12 and the motor cover insertion hole 13 cooperate to achieve the positioning and support of the motor end cover, which facilitates the positioning and testing in the later stage.

[0037] A fixed-point detection component is connected to the top rear end of the limit component 1. The fixed-point detection component includes a vertical position adjustment component, a detection component, and a sensing component. The vertical position adjustment component is connected to the limit component 1. The driving end of the vertical position adjustment component is connected to the sensing component and the detection component. The detection component is located outside the sensing component. The vertical position adjustment component drives the sensing component and the detection component to move downward. The detection component contacts the motor end cover. When the sensing value of the sensing component gradually increases before the vertical position adjustment component moves to the set position, the motor end cover does not meet the standard. When the sensing value of the sensing component does not change when the vertical position adjustment component moves to the set position, the motor end cover meets the standard. The measurement is error-free, and it can form a consistent inspection result for product quality inspection. It does not require high skills from inspectors, and the inspection method is easy to master. It can be used for large-scale inspection.

[0038] The vertical position adjustment assembly includes a cylinder 31, a mounting plate 32, and a movable plate 36. The mounting plate 32 is fixedly installed on the top of the support platform 11. The cylinder 31 is fixedly connected to the top of the mounting plate 32, and the movable plate 36 is fixedly connected to the driving end of the cylinder 31.

[0039] The detection assembly includes a protrusion 33, a slide rod 34, a mounting plate 35, a bearing housing detection block 37, and a mounting hole detection rod 38. The movable plate 36 is slidably connected to the slide rod 34 through a straight hole. The top of the slide rod 34 is fixedly connected to the protrusion 33, and the bottom of the slide rod 34 is fixedly connected to the mounting plate 35. The mounting hole detection rods 38 are symmetrically fixedly connected to the bottom of the mounting plate 35. The bottom of the mounting plate 35 is fixedly connected to the bearing housing detection block 37.

[0040] The sensing component is a pressure sensor 39, which is fixedly installed on the bottom of the movable plate 36, and the sensing end of the pressure sensor 39 is fixedly connected to the mounting plate 35.

[0041] When the cylinder 31 extends downward to half its length, the bearing housing detection block 37 and the mounting hole detection rod 38 are in the detection and positioning stage, and the distance between the bottom of the bearing housing detection block 37 and the mounting hole detection rod 38 and the support platform 11 is twice the height of the motor end cover.

[0042] The cylinder 31 of the vertical position adjustment component drives the movable plate 36 to continue moving downwards. The movable plate 36 drives the slide rod 34 of the sensing component and the pressure sensor 39 of the detection component to move downwards. The bearing chamber detection block 37 and the mounting hole detection rod 38 of the detection component move downwards. The bearing chamber detection block 37 and the mounting hole detection rod 38 contact the motor end cover. When the sensing value of the sensing component gradually increases before the vertical position adjustment component moves to the set position, the motor end cover does not meet the standard. When the sensing value of the sensing component does not change when the vertical position adjustment component moves to the set position, the motor end cover meets the standard. This facilitates accurate and rapid detection with no measurement error, and can form a unified inspection result for product quality inspection. It does not require high skills from inspectors and is easy to master. It can be used for large-scale inspection.

[0043] The vertical position adjustment component is connected to the lifting component 2. When the lifting component 2 moves upward, it pushes the motor end cover inside the support platform 11 upward.

[0044] The lifting assembly 2 includes a push rod 21, a push rod connecting plate 22, a connecting plate 23, a lifting hole 24, and a straight hole 25. The support platform 11 has a straight hole 25, and the connecting plate 23 is slidably connected inside the straight hole 25. The bottom of the connecting plate 23 is fixedly connected to the push rod connecting plate 22, and the top of the push rod connecting plate 22 is symmetrically fixedly connected to the push rod 21. The bottom of the support platform 11 has symmetrically opened lifting holes 24 that cooperate with the push rod 21.

[0045] The top of the connecting plate 23 is fixedly connected to the movable plate 36;

[0046] When the cylinder 31 extends to its highest point, the top of the push rod 21 is flush with the top of the support platform 11.

[0047] When the extension end of cylinder 31 moves downward to half of its extension, the top of push rod 21 is lower than the bottom of support platform 11.

[0048] Cylinder 31 drives movable plate 36 to move upward to the detection and positioning stage, and then continues to move upward. Movable plate 36 drives connecting plate 23 of lifting assembly 2 to move along straight hole 25. Straight hole 25 drives push rod connecting plate 22 to move. Push rod connecting plate 22 drives push rod 21 to move. Push rod 21 moves upward in lifting hole 24. Lifting hole 24 pushes motor end cover in motor cover insertion hole 13 to lift upward, realizing separation of motor end cover from limiting assembly 1.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any modifications and variations made by those skilled in the art without departing from the scope of the present invention using the disclosed methods are within the scope of the claims.
