Description

Technical Field

The invention relates to the field of abnormal sound testing devices, in particular to an abnormal sound testing feeding mechanism.

Background Art

In the field of industrial automation, abnormal sound testing is an important step in evaluating whether products (such as motors, bearings, etc.) produce abnormal sounds during operation, which is crucial to ensuring product quality. The two-stage pneumatic feeding mechanism widely used in the prior art mainly relies on air pressure drive, and realizes the automatic feeding process of materials through the coordinated work of multiple pneumatic components.

Although this structure has achieved automation to a certain extent, it has the following obvious technical defects:

1. Structural vibration problem: Due to the inherent instability and air pressure fluctuations of the pneumatic system, the entire mechanism is prone to vibration during the material feeding process, which not only affects the stability and accuracy of the material feeding, but may also cause damage to the material itself or affect the accuracy of the test results.

2. Insufficient positioning accuracy: The two-stage pneumatic structure cannot achieve precise control of the material position. In practical applications, it is often necessary to move the mechanism to the extreme position. This mechanical positioning method is inefficient and easily affected by external environmental factors (such as air pressure changes, wear, etc.), resulting in positioning accuracy that cannot meet the needs of abnormal sound testing.

3. Difficulty in speed control: The speed control of the pneumatic system is relatively complex and not precise enough, especially when the feeding speed needs to be fine-tuned to match different test requirements. The existing technology is difficult to achieve fast and accurate adjustment, which limits the test efficiency and flexibility.

In order to solve the defects in the above-mentioned prior art, the present invention proposes an innovative abnormal sound testing feeding mechanism.

DETAILED DESCRIPTION

In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are only connected to form a whole through a connecting structure. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

Embodiment, as shown in FIG. 1 to FIG. 8 , the present application provides an abnormal sound test feeding mechanism, which is used to prevent jitter and vibration during the loading and unloading and testing process, while improving the stability and uniformity of the overall operation.

As shown in FIG. 1 and FIG. 2 , a feeding mechanism for abnormal sound testing of the present invention comprises a mounting seat 1, on which a feeding mechanism 2 is provided, and the feeding mechanism 2 comprises a feeding plate 21 and a material mounting platform 22 provided on the feeding plate 21;

As shown in Figures 2 and 8, the feed plate 21 of the present invention is a rectangular long plate, and a connecting seat 211 is provided at one end of the upper surface of the feed plate 21. The material mounting platform 22 is clamped in the connecting seat 211, and the material mounting platform 22 is fixed to the feed plate 21 by screws. A storage groove 220 is provided on the material mounting platform 22, and the storage groove 220 is used to place the product to be inspected.

The entire equipment is installed in a semi-sealed environment. Only when the feeding plate 21 is extended can the products to be tested be placed and taken out. An abnormal sound testing device is arranged directly above the entire mounting seat 1. The abnormal sound testing device is fixed. When the feeding plate 21 is retracted, the material mounting table 22 is moved to the bottom of the abnormal sound testing device for testing.

In order to reduce the friction force of the feeding plate 21 during its movement, a sliding device 3 is provided at the bottom of the feeding plate 21 , and the feeding plate 21 is driven by a power device to slide back and forth on the sliding device 3 .

Specifically, as shown in Figures 2 and 3, the sliding device 3 of the present invention includes two slide rails 31, which are arranged in parallel. The two slide rails 31 are fixed to the lower surface of the feed plate 21. At the same time, two supporting sliders 32 are arranged on each slide rail 31. The slide rail 31 is slidably connected in the supporting slider 32, so that the slide rail 31 can only slide back and forth in a straight line.

Each supporting slider 32 is fixed on the mounting base 1 and fixed by screws, and each slide rail 31 slides and cooperates on the corresponding supporting slider 32. In order to provide further support and protect the stability of the slide rail 31, two auxiliary support platforms 33 are also provided on the mounting base 1. The auxiliary support platforms 33 are laid on the moving path of the slide rail 31. In addition to supporting the slider 32, the bottom of the slide rail 31 can also rest on the corresponding auxiliary support platform 33 when moving, which can reduce the pressure on the supporting slider 32 and reduce friction.

In order to solve the volatility and instability of the existing pneumatic system transmission mode, the entire mechanism is prone to shaking during the material feeding process, which not only affects the stability and accuracy of the material feeding, but may also damage the material itself or affect the accuracy of the test results. In addition, the driving time of the pneumatic transmission system is unstable and will change with the air pressure. The interval time of each transportation is different, so it is necessary to increase the waiting time in the middle until the product is transferred to the bottom of the abnormal sound test device, which increases the processing time in the middle.

In order to make the telescopic movement of the feeding plate 21 smoother, a motion control device 4 is also provided on the feeding plate 21. The motion control device 4 includes a driving motor 41 and a transmission connection device 42. The driving motor 41 drives the feeding plate 21 to move through the transmission connection device 42. The driving motor 41 is connected to a driving motor controller. The driving motor 41 generally adopts a servo motor or a stepping motor. The number of rotations can be accurately controlled according to the current input to achieve the control of the moving distance of the feeding plate 21.

In order to further increase the moving distance of the feeding plate 21, a gear transmission system is set up, as shown in Figures 4 and 5, a driving gear 411 is arranged on the output shaft of the driving motor 41, and the transmission connection device 42 includes a driven gear 421 and a driven gear seat 422. A synchronous belt 43 is arranged between the driving gear 411 and the driven gear 421, and a synchronous connecting block 44 is arranged on the synchronous belt 43. The synchronous connecting block 44 is fixed on the feeding plate 21, and the synchronous connecting block 44 is fixed on the feeding plate 21 by screws, and the synchronous connecting block 44 reciprocates between the driving gear 411 and the driven gear 421 along with the synchronous belt 43.

As shown in Figure 5, the driving gear 411 rotates forward and reversely to drive the synchronous belt 43 and the driven gear 421 to rotate, and the synchronous connecting block 44 drives the feeding plate 21 to move as the moving synchronous belt 43 moves, and the synchronous connecting block 44 only moves on the upper synchronous belt 43 between the driving gear 411 and the driven gear 421, and does not move downward as the synchronous belt 43 turns.

At the same time, the rotation speed of the driving gear 411 can also be adjusted to finely adjust the feeding speed to match different testing requirements.

In order to further improve the accuracy of the movement of the feeding plate 21 , a detection device 6 is further provided on the mounting base 1 , and the detection device 6 is used to detect and control the moving position of the feeding plate 21 .

As shown in Figure 2, the detection device 6 includes a sensor detection probe 61 and a grating ruler 62. The sensor detection probe 61 is fixed on the mounting base 1. The sensor detection probe 61 is located on the side of the moving track of the feed plate 21, and the grating ruler 62 is fixed on the side wall of the feed plate 21. Barcodes with different spacings are coated on the grating ruler 62. When the sensor detection probe 61 is irradiated on different barcodes, it will reflect the reflection code corresponding to the barcode. After decoding, the location information of the barcode can be obtained.

The sensor detection probe 61 can obtain the position information of the feed plate 21 by scanning the barcode on the grating ruler 62, and then the sensor detection probe 61 feeds back the detected position information to the drive motor controller, and the drive motor controller controls the forward and reverse rotation of the drive motor 41 according to the position information.

By setting a high-precision grating ruler and sensor detection probe as a position feedback device, the positioning accuracy is enhanced. The grating ruler can provide the controller with the position information of the structure movement in real time and accurately, and realize the fine control of the material position on the feed plate and the material mounting table by the drive motor. It not only meets the strict requirements of high-precision abnormal sound test on material positioning accuracy, but also improves the accuracy and repeatability of the test.

A clamping device 5 is also provided on the mounting seat 1 , and the clamping device 5 abuts against the upper surface of the feeding plate 21 .

As shown in Figures 4 and 5: In order to keep the feeding plate 21 stationary during loading and unloading and testing, a plurality of clamping members 51 are arranged on the mounting base 1. The clamping members 51 are symmetrically arranged on both sides. The clamping members 51 can fix the feeding plate 21 during loading and unloading and testing. The clamping members 51 can be set to an even number, such as 2, 4, 6, or 8.

The clamping device 5 of the present invention includes four clamping members 51, each of which rests against the upper surface of the feed plate 21 when the feed plate 21 is stationary. There are four clamping members 51 in total, two of which are arranged on both sides of the feed plate 21, and the four clamping members 51 are arranged symmetrically. By arranging four clamping members, the feed plate is fixed during the process of loading and unloading and testing, which effectively reduces the jitter and vibration during the process of loading and unloading and testing, improves the stability and reliability, and provides a stable environment for the smooth conduct of the abnormal sound test.

As shown in FIG. 6 , each pressing member 51 includes a rotating motor 511 and a lifting rod 512 . The rotating motor 511 provides power for turning in the horizontal direction, while the lifting rod 512 provides power for lifting in the vertical direction.

The end of the lifting rod 512 is provided with a connecting rod 513, and the bottom of the connecting rod 513 is provided with a pressing block 514. The rotating motor 511 drives the lifting rod 512 to rotate, and the lifting rod 512 moves up and down to make the pressing block 514 press or move away from the surface of the feeding plate 21. In order to reduce the impact force of the pressing block 514 pressing down, each pressing block 514 is made of silicone material, which has a certain elasticity and is not easy to damage the feeding plate 21.

Operation principle: As shown in Figures 1, 7 and 8, Figure 1 shows a normal transportation process. The driving motor 41 rotates to rotate the driving gear 411, which drives the synchronous belt 43 and the driven gear 421 to rotate, and then the synchronous connecting block 44 pushes the feeding plate 21 to control the telescopic movement, and the slide rail 31 and the supporting slider 32 cooperate to reduce friction.

At the same time, the sensor detection probe 61 can obtain the position information of the feeding plate 21 by scanning the bar code on the grating ruler 62, so that the feeding plate 21 can extend and move from the detection end to the loading and unloading end.

As shown in Figure 7, it is a state diagram of loading or unloading. At this time, the clamping blocks 514 of the four clamping members 51 are all pressed against the feeding plate 21 by the lifting rod 512 and maintained for a fixed time, so that the staff can place the product to be tested into the storage slot 220 of the material mounting table 22, and then the lifting rod 512 is lifted, the rotating motor 511 rotates, and the connecting rod 513 rotates 90 degrees to separate the clamping block 514 and the feeding plate 21.

Then, the product to be tested is transported in the form of FIG. 1 until the sensor detection probe 61 obtains the feed plate 21 reaching the bottom of the abnormal sound test device by scanning the bar code on the grating ruler 62, and then the rotating motor 511 is started to rotate, so that the connecting rod 513 rotates 90 degrees in the opposite direction, so that the clamping block 514 is above the feed plate 21, and then the lifting rod 512 is driven down to make the clamping block 514 rest on the feed plate 21. The product to be tested is fixed in the storage slot 220, and the abnormal sound test device is started to carry out the experiment.

After the experiment is completed, according to the above-mentioned operating principle, the clamping block 514 is removed, the feeding plate 21 is extended, and the feeding plate 21 is fixed with the clamping block 514, the product to be tested is removed, and a new product to be tested is replaced, and this operation is repeated.

In the present invention, by integrating a servo motor as a power source, using a driving gear and a driven gear, and transmitting through a synchronous belt and synchronous movement of a feed plate, it is beneficial to the smooth and precise control of the power output of the driving motor;

The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
