Technical Field

The invention relates to the technical field of test equipment, in particular to a static balance test device and method based on a coaxial reversing gear set structure.

Background

The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.

In many specific situations, a situation that two rotation directions are positive and negative are required to be presented on one shaft at the same time, in order to meet the use condition, most of the structures adopt a gear set connection mode, and 5 gears are driven by a single motor to be arranged through a specific method so as to achieve that the rotation directions of the gears on the shaft are opposite to the rotation directions of the shaft. Due to this difference in rotational direction, the on-shaft gear is not rigidly connected to the shaft itself, so that the center of mass of the on-shaft gear and the center of mass of the shaft cannot be integrated into one. Under the working condition, if the mass center of the gear on the shaft is not on the center line of the shaft, the mass center positions of the parts connected with the gear on the shaft are not on the same axis correspondingly, and the two parts can cause uncertain damage to the working environment.

Because the gear can not be modified after being processed, the gear-shaft static balance test is needed before the mechanism is put into production, so that the problem that the gear on the shaft and the center of mass of the shaft are not on the same axis is solved, and the requirement of protecting the subsequent use environment is met. The traditional detection method is to press the gear on the bearing manually, then place the gear-shaft on the horizontal platform to observe whether the rotation condition exists, if so, the center of mass of the gear is not in the center line of the shaft. And after the detection is finished, the gear is manually taken down, and then the next gear is mounted on the bearing for detection.

Example two

The embodiment provides a static balance test method based on a coaxial reversing gear set structure.

A static balance test method based on a coaxial reversing gear set structure adopts the static balance test device based on the coaxial reversing gear set structure according to the first embodiment, and comprises the following steps:

Placing the gear 8 on a material conveying mechanism, conveying the gear to a gear-shaft assembly mechanism by the material conveying mechanism, moving the pushing rod 13 from a first position to a second position, placing the gear 8 on a bearing 28 in the center of a gear testing mechanism, retracting the pushing rod 13 to the first position, determining whether the center of mass of the gear deviates from the axis by detecting whether pressure exists on the elastic pressure plate 10 by the pressure sensor 12, and sending a detection result to an electric control system;

And the electric control system sends corresponding control instructions to the sorting and collecting mechanism according to the detection result to collect the gears 8.

Referring to fig. 3, the static balance testing device includes: the working platform 1 is provided with fixed legs 37, and the working platform 1 is provided with a material conveying mechanism of fig. 4, a gear-shaft assembling mechanism of fig. 5 and a sorting and collecting mechanism of fig. 10.

Referring to fig. 4, a material conveying mechanism includes: conveyor supporting leg 3, conveyor 2, gear guide block 4, photoelectric switch 5, arc stand pipe 6 and inclined guide groove 7.

The support legs 3 fix the conveyor 2 at a certain height and place the gears 8 to be detected on the conveyor belt on the surface of the conveyor 2. Due to the structural characteristics of the gears, the gears need to be placed with a certain gap, and the teeth of the two gears cannot be crossed, so that the gears cannot be extruded with the gear guide block 4, and the meshing surface of the gears is damaged. The gear 8 on the conveyor 2 gradually approaches the center of the conveyor due to the gear guide block 4, so that the limit and position guide of the gear 8 are realized. At the position of the end of the gear guide block 4 close to the arc-shaped guide pipe 6, the guide block is provided with a photoelectric switch 5 for detecting whether the gear 8 exists at the current position. If it is detected that the gear 8 is not present here, the conveyor 2 is slowly operated under the control of the electronic control system so that the remote gear 8 is transported to the position of the photoelectric switch 5 in preparation for the subsequent process step. When the electronic control system sends a signal for providing the gear 8 for the gear-shaft assembly mechanism, the conveyor 2 starts to operate, the gear at the photoelectric switch 5 is transported into the arc-shaped guide tube 6, and the gear 8 falls into the lower gear placing block 14 of the gear-shaft assembly mechanism through the inclined guide groove 7 while changing the direction by means of gravity and the arc-shaped structure of the arc-shaped guide tube 6.

Referring to fig. 5-9, a gear-shaft assembly mechanism includes: the lower gear placing block 14, the upper gear placing block 9, the combined photoelectric switch 38, the gear placing block supporting seat 15, the pushing rod 13, the pushing rod placing seat 16, the position sensor 21, the first rocker arm 17, the second rocker arm 18, the motor 19, the motor placing seat 20, the elastic pressing plate 10, the spring 11 and the pressure sensor 12.

When the gear 8 falls into the lower gear placement block 14, the push rod 13 is at the first position. When the pusher reaches the first position, the signal of the position sensor 21 is fed back to the electronic control system by the presence of the small plate on the pusher 13, which sends a command to stop the motor 19, so that the pusher stops in the first position. When the combined photoelectric switch 38 on the lower gear-setting block 14 detects a signal at the same time, i.e. the gear 8 has reached the working position, it is fed back to the electronic control system, which at the same time sends a movement signal to the motor 19. After receiving the signal, the motor 19 rotates anticlockwise, the motor shaft drives the second rocker 18, the second rocker 18 drives the first rocker 17, the first rocker 17 drives the pushing rod 13, the pushing rod 13 only moves forwards at the moment due to the constraint of the pushing rod placing seat 16, then the gear 8 is pushed to the position of fig. 7 from the position of fig. 6, the rotating table 25 of the sorting and collecting mechanism is positioned at the first position, and the gear 8 is installed into the bearing 28 on the rotating shaft seat 27 under the pushing of the pushing rod 13. At the same time, the small plate on the pushing rod 13 breaks the signal of the position sensor 21 at the second position due to the forward movement of the pushing rod 13, and the electronic control system sends a command for stopping the operation of the motor 19 again. Because the upper gear placement block 9 and the sensor 22 on the lower gear placement block 14 allow the system to detect that the gear 8 passes through this area, the electronic control system will again give an operating command to the motor 19, at which time the motor shaft rotates clockwise bringing the propulsion lever 13 back to the first position. At this time, the command is repeated, and the pushing rod 13 can be made to reciprocate at a specific position. Wherein the sensor 22 may employ a non-correlation sensor, by emitting infrared light to determine whether the gear is between the "up-down gear placement blocks".

Since the gear 8 mounted in the bearing 28 is located at the center of the 4 elastic pressing plates 10, if the center of gravity of the gear 8 is not deviated from the rotation axis, the center of gravity of the gear 8 coincides with the axis of the bearing, i.e. the required static balance state is achieved, and the gear 8 will not touch the elastic pressing plates 10 at this time, and the pressure sensor 12 has no feedback system of signals. If the center of gravity of the gear 8 deviates from the rotation axis, the gear 8 will tilt to a certain side, so as to touch the elastic pressing plate 10, the elastic pressing plate 10 transmits the pressure to the pressure sensor 12 through the spring 11, and the pressure sensor 12 will provide a signal for the electric control system.

When the gear 8 passes through the sensor 22, the electric control system not only provides a working signal for the motor 19, but also provides another signal according to whether the pressure sensor 12 has feedback or not, when the pressure sensor 12 does not have feedback, the gear 8 meets the requirement, and at the moment, the electric control system can send an A instruction to the sorting and collecting mechanism; if there is feedback from the pressure sensor 12, meaning that the gear 8 is not satisfactory, a B command is issued for the sorting and collecting mechanism.

Sorting and collecting mechanism, comprising: bearing 28, bearing platen 39, rotary shaft seat 27, lead screw motor 26, rotary table 25, rotation sensor 34, rotary table gear 24, rotary table base 23, power gear 35, rotary motor 36, bi-directional cylinder 29, cylinder bracket 30, storage box shielding plate 32, counting sensor 31, and storage box 33.

Referring to fig. 10-15, upon command from the electronic control system a, the sort and collection mechanism executes the a motion logic and signals the conveyor 2 that the gear 8 is required to provide the gear-shaft assembly mechanism. The gear wheel 8 is now mounted on the bearing 28 and the rotary table 25 is in the first position. Under the control of the command A, the screw motor 26 first operates to enable the movable sliding block to move backward, so that the movable sliding block and the rotary shaft seat 27 connected with the movable sliding block move backward together, and the gear 8 is separated from the center of the elastic pressing plate 10. When the screw motor 26 runs to a specified position, the electric control system controls the rotating motor 36 to rotate clockwise under the requirement of the A instruction, the power gear 35 connected with the rotating motor 36 also rotates clockwise, the power gear 35 is meshed with the rotating table gear 24 sleeved on the rotating table base 23, the rotating table gear 24 rotates anticlockwise, and finally the rotating table 25 rotates anticlockwise by 90 degrees to reach a second position due to the fact that the rotating table 25 is connected with the rotating table gear 24. Since the rotation table's small plate interrupts the signal of the rotation sensor 34 placed on the left bin shield plate 32 when the second position is reached, the system issues a command to stop the rotation table 25 so that the rotation table 25 stops at the second position. At this time, the electric control system controls the bidirectional air cylinder 26 to work, so that the bidirectional air cylinder lifts the gear 8 at the second position, and the gear 8 is separated from the bearing 28 and falls into the left storage box 33. The gear 8 can pass through the counting sensor 31 on the storage box shielding plate 32 in the process of falling into the storage box 33, so that the gear 8 can be counted. After the jacking command is completed, the cylinder head is contracted into the cylinder interior. After the command of the bi-directional air cylinder 26 is completed, the electronic control system controls the rotary motor 36 to rotate 90 degrees counterclockwise back to the first position where the rotary table is located.

When commanded by the electronic control system B, the sorting and collecting mechanism executes the B motion logic and signals the conveyor 2 that the gear 8 is required to be provided to the gear-shaft assembly mechanism. The gear wheel 8 is now mounted on the bearing 28 and the rotary table 25 is in the first position. Under the control of the B instruction, the screw motor 26 first operates to enable the movable sliding block to move backward, so that the movable sliding block and the rotary shaft seat 27 connected with the movable sliding block move backward together, and the gear 8 is separated from the center of the elastic pressing plate 10. When the screw motor 26 is operated to a specified position, under the requirement of the B instruction, the electric control system controls the rotating motor 36 to rotate anticlockwise, the power gear 35 connected with the rotating motor 36 also rotates anticlockwise, the power gear 35 is meshed with the rotating table gear 24 sleeved on the rotating table base 23, so that the rotating table gear 24 rotates clockwise, and finally the rotating table 25 rotates clockwise by 90 degrees to reach a third position due to the fact that the rotating table 25 is connected with the rotating table gear 24. Since the rotation table's platelet interrupts the signal of the rotation sensor 34 placed on the right bin shield 32 when the third position is reached, the system becomes instructed to stop the rotation table 25 so that the rotation table 25 stops at the third position. At this time, the electric control system controls the bidirectional air cylinder 26 to work, so that the bidirectional air cylinder lifts the gear 8 at the third position, and the gear 8 is separated from the bearing 28 and falls into the right storage box 33. The gear 8 can pass through the counting sensor 31 on the storage box shielding plate 32 in the process of falling into the storage box 33, so that the gear 8 can be counted. After the jacking command is completed, the cylinder head is contracted into the cylinder interior. After the command of the bi-directional air cylinder 26 is completed, the electronic control system controls the rotary motor 36 to rotate 90 degrees clockwise to return to the first position where the rotary table is located.
