Description

Technical Field

[0001] This utility model belongs to the field of metronome manufacturing, specifically a metronome testing platform. Background Technology

[0002] Traditional testing methods for mechanical metronomes have certain drawbacks. Firstly, inspecting for minor scratches, cracks, wear, and other defects on the pendulum surface, as well as the clarity of scales and markings, requires operators to hold the metronome for extended periods, leading to hand fatigue and impacting testing efficiency and accuracy. Secondly, when testing beat frequency, interference from nearby workstations or production equipment can easily affect the test results, reducing the reliability of the testing. Utility Model Content

[0003] The purpose of this invention is to address the above problems by providing a metronome testing platform that can improve the comfort of staff during testing and reduce the impact of the external environment on the test results.

[0004] To achieve the above objectives, the present invention employs a metronome testing platform, comprising a worktable with a horizontally movable sliding platform at its upper end. A carrying plate is mounted on the upper end of the sliding platform, rotating around a horizontally positioned pivot. The rotation angle of the carrying plate is locked by a locking mechanism. One end of the carrying plate is connected to a vertical plate. A soundproof cover is mounted on the upper end of the worktable, with one side open. The sliding platform enters the soundproof cover from the open end. A soundproof plate adapted to the open end of the soundproof cover is mounted on the sliding platform. A testing device for detecting the metronome's beat frequency is installed inside the soundproof cover. The mechanical metronome is placed on the carrying plate, and the carrying plate is rotated to facilitate inspection of the pendulum's appearance and other features, thereby improving the operator's comfort during testing. Simultaneously, when it is necessary to test whether the beat frequency emitted by the mechanical metronome is normal, the sliding platform is pushed into the soundproof cover until the soundproof plate closes the open end of the cover, effectively isolating some external sound and reducing the influence of the external environment on the test results.

[0005] Furthermore, the locking mechanism includes a support rod rotatably mounted on the side end of the vertical plate. The support rod and the carrying plate are respectively positioned on both sides of the vertical plate, and a limiting part is arranged radially along the axis of rotation on the upper end of the sliding platform. When the support rod abuts against the limiting part, the swing angle of the carrying plate can be fixed.

[0006] Furthermore, the soundproof cover has a transparent area on at least one side, so that during the testing process, the staff can clearly observe the swing state of the pendulum without opening the soundproof cover, which facilitates real-time monitoring of the metronome's working status, timely detection of abnormalities, and improves the convenience and efficiency of the testing.

[0007] Furthermore, since the back of a metronome often has a certain curvature, it is prone to rotation when the carrier plate is tilted, making it difficult for operators to observe the pendulum and other components. To secure the metronome, a fixing mechanism is provided on one side of the carrier plate on the vertical plate. This fixing mechanism firmly secures the metronome, preventing rotation or displacement due to its own curvature or changes in the center of gravity. This ensures that the metronome maintains a stable posture, providing a good foundation for testing and improving the reliability of the test results.

[0008] Furthermore, the fixing mechanism uses a suction cup to hold the metronome in place, preventing it from rotating or shifting.

[0009] Furthermore, the fixing mechanism includes a clamping plate for holding the metronome, which may be located above the metronome to fix the metronome between the clamping plate and the carrier plate; or the clamping plate may be spaced apart along the axial direction of the rotating shaft and contact the two sides of the metronome.

[0010] The beneficial effects of this invention are as follows: When inspecting the appearance of a metronome, placing it on a carrier plate eliminates the need for operators to hold the metronome for extended periods, reducing hand fatigue and improving operator comfort. Simultaneously, when the sliding stage is pushed into the soundproof cover, the soundproof panel and cover work together to form a relatively enclosed inspection space, thus isolating some external interference noise and reducing the impact of neighboring workstations or external production equipment, thereby improving the accuracy of beat frequency detection.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0016] Example 1, as Figure 1As shown, the specific structure of this embodiment is a metronome detection platform, which includes a worktable 1. The upper end of the worktable 1 is provided with a sliding table 2 that moves laterally. In this embodiment, the sliding table 2 moves along the length direction of the worktable 1. In order to improve the stability of the sliding, the upper end of the worktable 1 is provided with a groove, and a slide rail in the same direction is provided in the groove. The sliding table is provided in the groove and moves on the slide rail. The upper end of the sliding table 2 is provided with a carrying plate 3. The carrying plate 3 is provided with a rotating shaft 4 at both ends of the worktable 1 along its length. The axial direction of the rotating shaft 4 is the same as that of the worktable 1 along its length. The rotating shaft 4 is rotatably mounted on a support at the upper end of the sliding table 2. The rotation angle of the carrying plate 3 is locked by a locking mechanism. The locking method can be that the rotating shaft is provided with a threaded section and a locking bolt is provided on the threaded section. The locking bolt is located at the outer end of the support. By tightening the locking bolt, the rotating shaft 4 is prevented from rotating, thereby achieving the locking effect. In this embodiment, the locking mechanism includes a support rod 9 rotatably mounted on the side end of the vertical plate 5. The upper end of the support rod 9 is mounted on the vertical plate through a rotating shaft. The support rod 9 and the carrying plate 3 are respectively placed on both sides of the vertical plate 5. The upper end of the sliding table 2 is provided with a limiting part 10 arranged radially along the rotating shaft 4. The upper end surface of the limiting part 10 is higher than the upper end surface of the sliding table 2. The lower end of the support rod 9 abuts against the side end of the limiting part 10, thereby fixing the rotation angle of the carrying plate 3. The vertical plate 5 is fixedly mounted on the upper end of the carrier plate 3. The vertical plate 5 can be configured to match the curvature of the back of the metronome, with the front of the metronome being the surface where the swing arm is located. A fixing mechanism is provided on one side of the vertical plate 5 on the carrier plate 3. The fixing mechanism is a suction cup 12; or the fixing mechanism includes clamping plates 13, which are spaced apart along the axial direction of the rotating shaft 4, and the distance between the two clamping plates 13 is adapted to the width of the metronome.

[0017] A soundproof cover 6 is provided on the upper end of the workbench 1. The soundproof cover 6 is open at one end along the length of the workbench 1. The sliding table 2 enters the soundproof cover 6 from the open end. A soundproof plate 7 is provided on the sliding table 2, which is adapted to the open end of the soundproof cover 6. That is, the outer diameter of the soundproof plate 7 is adapted to the inner diameter of the open end of the soundproof cover 6. The soundproof plate 7 and the soundproof cover 6 can be enclosed to form a box-shaped structure. The soundproof plate 7 and the soundproof cover 6 are made of hard plastic, metal or other materials, and are covered with sound-absorbing cotton or the like. Although they cannot completely isolate external sound, they can reduce the influence of external sound on the test results. The soundproof cover 6 is equipped with a detection device 8 for detecting the beat frequency of the metronome. The detection device 8 adopts the frequency meter and audio analyzer of the prior art. A transparent area 11 is provided on the front side (i.e., the side facing the worker) of the soundproof cover 6. The transparent area 11 is made of acrylic, glass or other materials.

[0018] During testing: The mechanical metronome is placed on the carrier plate 3, with the swing arm of the metronome facing the worker, and the metronome is fixed in place by the fixing mechanism. When it is necessary to inspect the appearance of the swing arm, the carrier plate 3 can be rotated so that the swing arm faces the worker, making it convenient for the worker to inspect. When it is necessary to test the beat frequency, the sliding table 2 is pushed into the soundproof cover 6. The soundproof plate 7 and the soundproof cover 6 cooperate to form a relatively closed testing space, and the testing device 8 detects the sound emitted by the metronome.
