Description

Technical Field

[0001] The utility model relates to the technical field of motor base detection, in particular to a device for detecting the coaxiality and parallelism of a motor base. Background Art

[0002] From the analysis of the number and types of parts, the motor is a mechanical device with a relatively simple structure and can achieve electromagnetic conversion well. In the motor, the base is an important hardware component. The base is mainly used as a mechanical support for the stator core and windings, and is used to fix the end cover or end shield. The existing motor base has a full-circle structure with good rigidity and easy processing. After the motor base is processed and formed, the length needs to be measured to measure whether the parallelism of the motor base meets the standard.

[0003] After the motor base is produced, it needs to be tested for coaxiality and horizontality. Due to the different sizes of motor bases, different measuring devices need to be replaced for testing, which is troublesome, time-consuming and labor-intensive, thus reducing work efficiency. Moreover, it is not convenient to test the coaxiality and horizontality at the same time during the test. The motor base itself is heavy, and it is more laborious to move it around, which increases the workload and also poses a safety hazard. Utility Model Content

Since different sizes of motor bases require replacement of different measuring devices for testing, it is troublesome, time-consuming and labor-intensive, thereby reducing work efficiency. Moreover, it is not convenient to test the coaxiality and horizontality at the same time during the test. The motor base itself is heavy, and it is laborious to move it around, thereby increasing the workload and posing a safety hazard.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a device for detecting the coaxiality and parallelism of a motor base, comprising: a detection platform, a slide groove is opened at the center of the outer surface of the top of the detection platform, a bidirectional screw is movably embedded in the slide groove, and further comprising:

[0006] A mounting plate, fixedly mounted on one side of the detection platform, a servo motor is fixedly mounted on the outer surface of the mounting plate, and an output end of the servo motor is connected to one end of a bidirectional screw;

[0007] Two sliders are movably sleeved on the outer surface of the bidirectional screw, the two sliders are movably embedded in the inner part of the slide groove, and the tops of the two sliders are provided with electric push rods;

[0008] Two connecting plates are fixedly mounted on the tops of the two electric push rods, and multiple electric telescopic rods are arranged on the upper and lower sides of the opposite surfaces of the two connecting plates, and arc-shaped plates 1 are fixedly mounted on the opposite ends of the multiple electric telescopic rods;

[0009] An infrared emitter is arranged on the outer surface of one of the connecting plates;

[0010] The infrared receiver is arranged on one side of the other connecting plate close to the infrared transmitter.

[0011] Preferably, an L-shaped plate is fixedly mounted on one side of the detection platform close to the top outer surface, a hydraulic cylinder is fixedly mounted on the L-shaped plate close to the center of the top outer surface, and an output end of the hydraulic cylinder passes through the L-shaped plate.

[0012] The technical effect of adopting the above further solution is that the hydraulic cylinder can better drive the arc plate 2 to contact the outer surface of the motor base, so as to check the horizontality of the motor base.

[0013] Preferably, a connector is fixedly mounted on the output end of the hydraulic cylinder, a connecting block is movably embedded inside the connector, and an arc-shaped plate 2 is fixedly mounted on the bottom of the connecting block.

[0014] The technical effect of adopting the above further solution is that the arc plate 2 fits the outer surface of the motor base, and the indicator arrow set at the center does not change its angle, which means that the parallelism of the motor base is qualified.

[0015] Preferably, an indicator arrow is fixedly mounted at the center of the outer surface of one side of the arc-shaped plate.

[0016] The technical effect of adopting the above further solution is that the indicating arrow can more clearly observe the parallelism of the motor base.

[0021] Preferably, an anti-skid plate is fixedly mounted on the bottom of each of the plurality of adjusting screws.

[0022] The technical effect of adopting the above further solution is that the anti-slip plate can better improve the stability of the test bench.

[0023] Preferably, a bubble level is provided on a side of the testing platform away from the L-shaped plate.

[0024] The technical effect of adopting the above further solution is: adjusting the parallelism of the detection platform by means of a bubble level.

[0025] Compared with the prior art, the advantages and positive effects of the utility model are:

[0026] 1. In the utility model, a bubble level is arranged on one side of the inspection platform, and a plurality of adjusting screws are rotated and adjusted inside the threaded sleeve to make the bubble inside the glass tube of the bubble level remain at the highest position. In this way, the inspection platform remains horizontal, which can improve the accuracy of detecting the horizontality of the motor base. The motor base is placed at the center of the upper end of the inspection platform, and then the servo motor is started to drive the bidirectional screw to rotate forward. The bidirectional screw drives the two sliders to move out relatively while rotating forward, so that the coaxiality detection equipment is moved to the two ends of the motor base, so that the connecting plate is embedded inside it, and at the same time, the two sets of electric telescopic rods are opened to drive the arc plate to fit with the inner wall of the motor base. While the electric telescopic rod is moved and adjusted, the electric push rod is also lifted and adjusted accordingly, so that the connecting plate can be better embedded in the center of the two ends of the motor base. The infrared light emitted by the infrared transmitter can be received by the infrared receiver arranged at the other end. If the coaxiality of the motor base is qualified, otherwise it is unqualified.

[0027] 2. In the utility model, the hydraulic cylinder drives the arc plate 2 connected by the connector to fit with the outer surface of the motor base. An indicator arrow is set at the center of one side of the arc plate 2. When the arc plate 2 is fitted to the outer surface of the base that is not parallel to the test bench, the arc plate 2 will rotate inside the connector under the action of the connecting block, and the indicator arrow will also tilt with the inclination of the arc plate 2, so that the position indicated by the indicator arrow to the outer surface of the angle indicator plate is different, and therefore the horizontality of the motor base is unqualified.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0036] Embodiment 1, as Figure 1-4As shown, the utility model provides a device for detecting the coaxiality and parallelism of a motor base, comprising: a detection platform 1, a slide groove 105 is provided at the center of the top outer surface of the detection platform 1, and a bidirectional screw 106 is movably embedded in the slide groove 105, and also comprises: a mounting plate 2, which is fixedly mounted on one side of the detection platform 1, and a servo motor 201 is fixedly mounted on the outer surface of the mounting plate 2, and the output end of the servo motor 201 is connected to one end of the bidirectional screw 106; two sliders 107, which are movably sleeved on the outer surface of the bidirectional screw 106, and the two sliders 107 are both movably embedded in the slide groove 105, and the tops of the two sliders 107 are both provided with electric push rods 108; two connecting plates 109, which are both fixedly mounted on the two electric push rods 108. At the top of the push rod 108, multiple electric telescopic rods 110 are arranged on the upper and lower sides of the opposite surfaces of the two connecting plates 109, and the opposite ends of the multiple electric telescopic rods 110 are fixedly installed with an arc plate 111; an infrared transmitter 112 is arranged on the outer surface of one of the connecting plates 109; an infrared receiver 113 is arranged on the side of the other connecting plate 109 close to the infrared transmitter 112; threaded sleeves 101 are fixedly installed at the four corners of the outer surface of the bottom of the detection platform 1, and the interiors of the multiple threaded sleeves 101 are threadedly installed with adjusting screws 102; the bottoms of the multiple adjusting screws 102 are fixedly installed with anti-skid plates 103; a bubble level 104 is arranged on the side of the detection platform 1 away from the L-shaped plate 114.

[0037] In this embodiment, the bubble level 104 set on one side of the inspection platform 1 is observed, and the multiple adjusting screws 102 are rotated and adjusted inside the threaded sleeve 101 to keep the bubble inside the glass tube of the bubble level 104 at the highest position. In this way, the inspection platform 1 is kept horizontal, which can improve the accuracy of the horizontality of the motor base. The motor base is placed at the center of the upper end of the inspection platform 1, and then the servo motor 201 is started to drive the bidirectional screw 106 to rotate forward. The bidirectional screw 106 rotates forward and drives the two sliders 107 to move out relatively, thereby Move the coaxiality detection equipment to the two ends of the motor base, embed the connecting plate 109 therein, and simultaneously open the two sets of electric telescopic rods 110 to drive the arc plate 111 to fit the inner wall of the motor base. When the electric telescopic rods 110 are moved and adjusted, the electric push rods 108 are also raised and lowered accordingly, so that the connecting plate 109 can be better embedded in the center of the two ends of the motor base. If the infrared light emitted by the infrared transmitter 112 can be received by the infrared receiver 113 set at the other end, the coaxiality of the motor base is qualified, otherwise it is unqualified.

[0038] Embodiment 2, as Figure 1-4As shown, an L-shaped plate 114 is fixedly installed on one side of the testing platform 1 close to the top outer surface, a hydraulic cylinder 115 is fixedly installed at the center of the L-shaped plate 114 close to the top outer surface, and the output end of the hydraulic cylinder 115 passes through the L-shaped plate 114; a connector 119 is fixedly installed at the output end of the hydraulic cylinder 115, a connecting block 120 is movably embedded inside the connector 119, and an arc-shaped plate 116 is fixedly installed at the bottom of the connecting block 120; an indicator arrow 117 is fixedly installed at the center of the outer surface of one side of the arc-shaped plate 116; an angle indicator plate 118 is provided at the center of one side of the connector 119 close to the indicator arrow 117.

[0039] In this embodiment, the hydraulic cylinder 115 drives the arc plate 116 connected by the connector 119 to fit with the outer surface of the motor base. An indicator arrow 117 is set at the center of one side of the arc plate 116. When the arc plate 116 is fitted to the outer surface of the base that is not parallel to the test table 1, the arc plate 116 will rotate inside the connector 119 under the action of the connecting block 120, and the indicator arrow 117 will also tilt with the inclination of the arc plate 116, so that the position indicated by the indicator arrow 117 to the outer surface of the angle indicating plate 118 is different, so the horizontality of the motor base is unqualified.

[0040] Working principle: When in use, observe the bubble level 104 set on one side of the test platform 1, rotate multiple adjusting screws 102 to rotate and adjust inside the threaded sleeve 101, so that the bubble inside the glass tube of the bubble level 104 is kept at the highest position, so that the test platform 1 remains horizontal, which can improve the accuracy of the horizontality of the motor base. Place the motor base at the center of the upper end of the test platform 1, and then start the servo motor 201 to drive the bidirectional screw 106 to rotate forward. The bidirectional screw 106 rotates forward and drives the two sliders 107 to move out relative to each other, so that the coaxiality detection equipment moves to the two ends of the motor base, so that the connecting plate 109 is embedded inside it, and at the same time, the two sets of electric telescopic rods 110 are opened to drive the arc plate 111 to fit the inner wall of the motor base. While the electric telescopic rod 110 is moved and adjusted, the electric push rod 108 is also adjusted up and down accordingly. In order to better enable the connecting plate 109 to be embedded in the center of the two ends of the motor base, the infrared light emitted by the infrared transmitter 112 can be received by the infrared receiver 113 set at the other end, then the coaxiality of the motor base is qualified, otherwise it is unqualified. While the coaxiality is detected, the hydraulic cylinder 115 drives the arc plate 116 connected by the connector 119 to fit with the outer surface of the motor base. An indicator arrow 117 is set at the center of one side of the arc plate 116. When the arc plate 116 is fitted on the outer surface of the base that is not parallel to the test table 1, the arc plate 116 will rotate inside the connector 119 under the action of the connecting block 120, and the indicator arrow 117 will also tilt with the tilt of the arc plate 116, so that the position indicated by the indicator arrow 117 to the outer surface of the angle indicator plate 118 is different, so the horizontality of the motor base is unqualified.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
