Description

Technical Field

[0001] This utility model belongs to the technical field of static balance testing, specifically, it relates to a static balance testing device for rotating parts. Background Technology

[0002] Rotating workpieces require static balancing tests before assembly. Currently, static balancing tests are generally performed using static balancing machines. This method mainly uses specialized logistics and programs to automatically load and unload wheels and automatically position and test product balance. While this equipment saves labor intensity, the equipment cost is very high. To improve the accuracy of static balancing tests, the guide rails of static balancing testing equipment are usually shaft-type supports. Application number: CN202011152283.3 discloses a wheel hub static balancing testing device. Through the cooperation of a base plate, slot, insert plate, guide rail, horizontal shaft, wheel hub, and leveling components, the device can quickly determine and adjust uneven positions based on the annular equidistant distribution of screws, support feet, etc., and the setting of a leveling bubble, thereby improving leveling efficiency. However, the insert plate and guide rail of this device are fixedly connected. When the two guide rails are not level due to long-term wear, the integrated guide rail insert plate structure cannot adjust the support position of the guide rails, and the repair process of the guide rail support position is difficult and the overall replacement cost is high.

[0003] In view of this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a static balance testing device for rotating parts. The basic concept of the technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows:

[0005] A static balance testing device for rotating parts includes a support base plate and a side support frame. The side support frame has an L-shaped structure, and a testing support seat is fixedly mounted on the upper end of the side support frame.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0024] like Figures 1 to 5As shown, a static balance testing device for rotating parts includes a base plate 1 and a side support frame 4. The side support frame 4 has an L-shaped structure, and a testing support seat 5 is fixedly installed at the upper end of the side support frame 4. The testing support seat 5 has a U-shaped structure, and threaded holes 16 are provided at both ends of the testing support seat 5. Locking screws 8 are installed in the threaded holes 16. The threaded holes 16 extend into the testing support seat 5 and are provided with a mating groove 17. A track support locking shaft 12 is fitted in the mating groove 17. The end of the support locking shaft 12 corresponding to the threaded hole 16 is provided with a rotating fitting. The locking screw 8 and the support locking shaft 12 are fitted with a rotating fitting end 19 at one end of the groove 18. The rotating fitting end 19 is located in the rotating fitting groove 18. The U-shaped interior of the detection support base 5 is a track mounting groove 13. The detection track 6 is set in the track mounting groove 13. The detection track 6 is a cylindrical structure. The two ends of the detection track 6 are respectively provided with track fitting end grooves 15. The shape and specifications of the track fitting end are adapted to the shape and specifications of the support locking shaft 12. The detection track 6 is fixedly installed by the locking screw 8 and the support locking shaft 12.

[0025] The rotating mating end 19 is provided with a pressing anti-slip pad 20, and the pressing surface of the pressing anti-slip pad 20 is provided with anti-slip particles. The support locking shaft 12 has a hexagonal structure, which limits the detection track 6 to prevent the detection track 6 from rotating relative to the detection support seat 5.

[0026] Limiting end blocks 7 are fixedly installed at both ends of the upper part of the detection support 5. The limiting end of the limiting end block 7 is an arc surface structure, and a buffer pad 14 is provided inside the arc surface structure of the limiting end block 7 for limiting and buffering.

[0027] A support base 2 is installed on the bottom surface of the support base plate 1. The support base 2 is connected to the support base plate 1 by a thread. The support base 2 is provided with a support adjustment hole 3. The support base 2 can be adjusted through the support adjustment hole 3 to ensure that the support base plate 1 is in a horizontal state.

[0028] There is a gap between the detection track 6 and the bottom surface of the track mounting groove 13 of the detection support seat 5. A stable support pad 9 is inserted and installed in the gap to improve the support stability of the detection track 6 during the detection process.

[0029] A storage box 10 is provided on the support base plate 1 between the side support frames 4. A handle 11 is provided at the end of the storage box 10. A cover plate is provided on the storage box 10. The storage box 10 can be removed from the support base plate 1, thereby improving the diameter detection range of rotating parts.

[0030] The working principle of this utility model is as follows:

[0031] Example 1: When performing static balance testing on rotating parts, first use a level to check the level of the support positions of the two testing tracks 6 to ensure that the support positions of the testing tracks 6 are in a horizontal state. If the support positions of the two testing tracks 6 are not horizontal, they need to be adjusted or repaired.

[0032] Adjustments are made using the support base 2, which has support adjustment holes 3. With the help of an adjustment wrench, the support base 2 can be adjusted. A level is placed on the support base plate 1 to check its level, ensuring it is horizontal. Then, the testing track 6 is retested. If the support position of the testing track 6 is horizontal, the parts can be balanced. If the support position of the testing track 6 is not horizontal, or if there is wear or other issues with the current support position, the locking screw 8 can be turned outwards to move the support locking shaft 12 outwards, releasing the lock on both ends of the testing track 6 and allowing it to rotate a certain angle. For example, if the support locking shaft 12 is a hexagonal structure, it can rotate 60 degrees to replace the support position of the testing track 6. Afterwards, the testing track 6 is locked, and a horizontal retest is performed. In other words, the testing track 6 is detachable and can be rotated at different angles to perform static balance testing.

[0033] Example 2: If the detection level cannot be achieved after multiple rotations and adjustments, it indicates that the support positions of the detection track 6 are damaged to varying degrees. In this case, the detection track 6 needs to be removed and subjected to overall grinding and finishing. The detection track 6 is a single-axis structure without any fixed additional components, making the grinding and finishing process convenient. Grinding can ensure that both detection tracks 6 have good surface roughness and reduce the frictional resistance during the static balance detection process.

[0034] Example 3: The specific testing process is as follows: After placing the rotating part to be tested on the testing track 6, the edge of the rotating part is moved slightly to make it swing. Due to gravity, a certain part of the rotating part will always be at the bottom. No matter how the position is changed, this part will always be at the bottom. This is the eccentric position of the part. This position is thicker than other parts or for other reasons. Then, use a marker or chalk to mark the bottom heavy position and the top highest position is the light position. These are relative positions. Then, place a magnet at the light position, that is, the top position when the part is stationary, with a weight of 3 or 5 grams. The weight can be adjusted as needed. The purpose is to measure the approximate weight of the heavy position. Then, rotate the magnet and the eccentric position to a position parallel to the horizontal support. The purpose is to keep the eccentric position and the magnet position balanced. The weight of the magnet can be increased or decreased as needed until it is balanced. After this balance is achieved, slowly rotate the position. If the part can stop at any position, it means that the configuration and size of the eccentric position and the magnet are appropriate. Finally, the weight of the eccentric position is removed by milling or other methods.

[0035] This utility model features a detection support base 5 fixedly mounted above the side support frame 4. The detection support base 5 has a U-shaped structure design, and a detection track 6 is provided in the track mounting groove 13 of the detection support base 5. The two ends of the detection track 6 are locked to the detection support base 5 by a support locking shaft 12. The detection track 6 is a detachable structure, and the radial position of the support can be adjusted for easy inspection, maintenance, and adjustment. Track mating end grooves 15 are provided at both ends of the detection track 6. By engaging the locking screws 8 with the detection support base 5, the horizontal adjustment of the support locking shaft 12 can be achieved, thereby enabling the disassembly and assembly of the detection track 6. Limiting end blocks 7 are provided at both ends of the detection support base 5 to limit the end of the static balance detection process, preventing parts from sliding off the detection track 6 during the detection process and improving the safety of the detection process.
