Description

Technical Field

[0001] This invention relates to the field of harmonica reed thickness detection technology, specifically a harmonica reed thickness detection device. Background Technology

[0002] Harmonica reed thickness testing is crucial to the instrument's performance and quality, primarily in the following aspects: Reed thickness and pitch: Reed thickness is a core factor affecting vibration frequency. For the same length, a thicker reed vibrates more slowly and produces a lower pitch; conversely, a thinner reed produces a higher pitch. Thickness testing ensures that reeds in each register conform to the design pitch, avoiding intonation deviations. Compensating for manufacturing errors: Reed processing may result in uneven thickness, such as larger errors in lower-end products. Testing can screen out reeds with substandard thickness, ensuring consistent intonation before delivery.

[0003] In existing technologies, harmonica reed thickness is mainly measured using a micrometer. During testing, the harmonica reed is placed on an anvil, and the micrometer screw is rotated to press the reed firmly against the anvil. After a "click" sound is heard, rotation is stopped, and the micrometer screw is locked with a locking wrench. The scale value on the micrometer screw is then read. Harmonica reeds whose thickness meets a certain tolerance range are considered qualified products. Currently, harmonica reed testing requires placing each reed individually on the anvil for pressing, and the testing operation is repeated continuously, which is time-consuming and labor-intensive. The efficiency of harmonica reed thickness testing is low and the speed is slow, making it difficult to test a large number of harmonica reeds simultaneously and distinguish qualified products. Summary of the Invention

[0004] This invention provides a harmonica reed thickness detection device, which, through the cooperation of a first push plate inside a placement slot and a second push plate inside a guide slot, can horizontally push the harmonica reeds on the first push plate onto a sealed airbag on a measuring anvil.

[0016] The present invention has the following beneficial effects:

[0017] 1. This harmonica reed thickness detection device, through a measuring anvil fixed on a hollow testing platform, facilitates the simultaneous thickness detection of several harmonica reeds. Several circumferentially spaced placement slots on the annular feeding seat facilitate the simultaneous placement of several harmonica reeds to be tested. A first push plate within the placement slot pushes the harmonica reeds upwards during feeding. A second push plate within the guide slot horizontally pushes the reeds on the first push plate onto the sealed airbag on the measuring anvil. This achieves the purpose of synchronous feeding of several harmonica reeds for testing, greatly improving the convenience of feeding multiple harmonica reeds, saving time and effort, and providing a quick and easy experience.

[0018] By using the threaded rod connected to the mounting block, the horizontal movement of the wedge-shaped contact bar within the annular feeding seat can be adjusted during rotation. This causes the wedge-shaped contact bar to contact the first contact ring, which in turn causes several first contact rods to move the first push plate upward within the placement groove. This adjusts the vertical feeding height of several harmonica reeds. As the wedge-shaped contact bar continues to move, the first contact wedge on the wedge-shaped contact bar contacts the second contact ring, causing the second contact ring to move upward and contact the second contact wedge fixed at one end of several second contact rods. This allows the second push plate to automatically push the harmonica reeds onto the anvil for testing.

[0019] 2. This harmonica reed thickness detection device facilitates the installation of several sealing airbags through a circular groove on the anvil. The height of the sealing airbags protrudes from the surface of the anvil. The piston cylinder fixed on the anvil can communicate with the sealing airbags. When the sealing airbags are compressed, the gas generated is delivered into the piston cylinder, which can push the piston plate and piston rod to move horizontally within the piston cylinder. The greater the deformation of the sealing airbags, the greater the distance the piston plate moves within the piston cylinder. Through the cooperation of the corresponding magnification component and the scale display column, the deformation of the sealing airbags can be magnified, thus allowing the staff to directly observe the changes in the value of the compressed sealing airbags with the naked eye.

[0020] The micro-measuring screw mounted on the L-shaped ruler rotates, causing the test disc to move downwards and press against the harmonica reed on the sealed airbag until the reed contacts the surface of the anvil. If the thickness of the tested harmonica reed is greater than the upper limit of the specified thickness tolerance, the corresponding sealed airbag will be compressed first, with a large deformation and a large piston movement distance. If the thickness of the tested harmonica reed is less than the lower limit of the specified thickness tolerance, the sealed airbag experiences less compression, smaller deformation, and a smaller piston movement distance. If the thickness of the tested harmonica reed is within the specified thickness tolerance range, the sealed airbag experiences moderate compression, moderate deformation, and a moderate piston movement distance. By amplifying the deformation of the sealed airbag through the corresponding amplification components, it is convenient for staff to observe the changes in the corresponding scale display column and determine whether the thickness of several tested harmonica reeds meets the specified thickness tolerance range. This greatly improves the efficiency of distinguishing between qualified and unqualified harmonica reeds. Attached Figure Description

[0034] A mounting block 101 is fixed on the base 1. A threaded rod 19 is threadedly connected to the mounting block 101. A wedge-shaped abutment strip 8 is rotatably connected to the end of the threaded rod 19. The wedge-shaped abutment strip 8 is slidably connected to the annular feeding seat 3, and one end of the wedge-shaped abutment strip 8 abuts against the first abutment ring 11.

[0035] A sliding frame 20 is fixed on the circumferential surface of the annular feeding seat 3. A second abutment ring 21 is slidably connected to the sliding frame 20. A second spring 22 is connected between the second abutment ring 21 and the sliding frame 20. A first abutment wedge block 23 is fixed on the wedge-shaped abutment strip 8.

[0036] A second abutting rod 24 is fixed on the second push plate 7. The second abutting rod 24 is elastically connected to the guide groove 6 through the third spring 25. A second abutting wedge 26 is fixed to one end of the second abutting rod 24. The second abutting wedge 26 abuts against the first abutting wedge 23.

[0037] The test end of the micrometer screw 10 is fixed with a test plate 31, which is opposite to the anvil 32. The L-shaped ruler 9 is equipped with a locking wrench 33 for locking the micrometer screw 10.

[0038] A piston cylinder 27 is fixed on the anvil 32. An amplification component is provided between the piston cylinder 27 and the scale display column 14. A piston plate 28 is slidably connected inside the piston cylinder 27. A piston rod 29 is fixed on the piston plate 28. The piston rod 29 is slidably connected to the piston cylinder 27. A fourth spring 30 is connected between the piston plate 28 and the piston cylinder 27. The piston cylinder 27 is connected to the sealing airbag 13 through a pipe.

[0039] The amplification component includes a water outlet 271, which is fixed to one side of the piston cylinder 27 and connected to a water supply pipe 272. The scale display column 14 is fixed to the anvil 32 and has a cavity 273. One end of the water supply pipe 272 is connected to the scale display column 14 and the water supply pipe 272 is connected to the cavity 273.

[0040] refer to Figures 1-3Before the harmonica reed thickness is tested, several harmonica reeds are placed sequentially into several placement slots 4 on the annular loading seat 3. Then, the threaded rod 19 connected to the mounting block 101 is manually rotated. During the rotation of the threaded rod 19, the wedge-shaped contact strip 8 connected to its end can move horizontally within the annular loading seat 3. During the movement of the wedge-shaped contact strip 8, it can make contact with the first contact ring 11. The guide hole 17 on the first contact ring 11 is fitted onto the first guide post 18 fixed on the annular loading seat 3, so that the first contact ring 11, which is being contacted, moves upward as a whole on the first guide post 18. This can achieve the purpose of pushing several first contact rods 15 to move vertically synchronously within several placement slots 4. The first spring 16 stores force, causing the first push plate 5 to push the harmonica reeds in the placement slots 4 upward, so that the bottom surface of several harmonica reeds is slightly higher. The horizontal height of the upper surface of the sealing airbag 13 facilitates the movement of the harmonica reeds in the horizontal direction, allowing them to move onto the sealing airbag 13. When the wedge-shaped contact strip 8 continues to move, the first contact wedge 23 on the wedge-shaped contact strip 8 can contact the second contact ring 21, causing the second contact ring 21 to slide vertically on the sliding frame 20 fixed on the annular feeding seat 3. The second spring 22 stores force, and when the second contact ring 21 moves upward, the annular feeding seat 3 and several second contact wedges 26 can contact each other simultaneously. When affected by the contact force, the second contact wedge 26 can drive the second contact rod 24 to move horizontally on the guide groove 6. The third spring 25 stores force, causing the second push plate 7 to push the harmonica reeds on the first push plate 5 to automatically move horizontally to the sealing airbag 13 on the anvil 32, thus achieving the purpose of feeding several test harmonica reeds simultaneously.

[0041] Because the harmonica reed is narrow and the upper contact area of ​​the sealing airbag 13 is small, the guide groove 6 can guide the movement of the harmonica reed, so that one end of the harmonica reed rests on the sealing airbag 13 and the other end is located in the guide groove 6. This solves the problem that the harmonica reed is easy to slip off the sealing airbag 13 when manually placed, and can greatly improve the stability of the feeding position of several tested harmonica reeds and the accuracy of thickness detection.

[0042] When measuring thickness, refer to Figures 1 to 7First, determine the upper and lower limits of the thickness tolerance of qualified harmonica reeds. By rotating the micrometer screw 10 on the L-shaped ruler 9, the test end of the micrometer screw 10 drives the test plate 31 to move vertically downward and press against the surface of several harmonica reeds. When the test end of the micrometer screw 10 continues to rotate, it can cause the test plate 31 to continuously press down on several harmonica reeds, so that several sealing airbags 13 are squeezed at the same time, deform and retract into the circular groove 12 opened on the anvil 32 until the micrometer screw 10 stops moving. At this time, one of the harmonica reeds is pressed against the surface of the anvil 32, limiting the downward movement of the micrometer screw 10. By rotating the locking wrench 33, the micrometer screw 10 is locked to avoid deviation when reading the test value and improve the accuracy of the harmonica reed thickness data reading.

[0043] If the thickness of the harmonica reed being tested exceeds the upper limit of the specified thickness tolerance, the corresponding sealing bladder 13 will be compressed first, and the deformation of the sealing bladder 13 will be large. This will cause the gas inside the sealing bladder 13 to be compressed and transported to the piston cylinder 27 through the pipe. The pressure will push the piston plate 28 inside the piston cylinder 27 and the piston rod 29 fixed on the piston plate 28 to move horizontally synchronously. When one end of the piston cylinder 27 is filled with water, the piston plate 28 can compress the water as it moves inside the piston cylinder 27. The fourth spring 30 will then store force, causing the water to be discharged through the outlet 271 on one side of the piston cylinder 27 and flow into the cavity 273 in the scale display column 14 through the water supply pipe 272. The display column 14 is transparent and has water level markings on its surface, allowing operators to visually observe changes in water level within the column. When the thickness of the harmonica reed being tested exceeds the upper limit of the specified thickness tolerance, the piston plate 28 moves a considerable distance within the piston cylinder 27, causing the water to rise significantly within the cavity 273 of the column. Through the coordination of the outlet 271, water pipe 272, column 14, and cavity 273, the deformation of the sealing airbag 13 can be amplified, facilitating the determination of whether the thickness of the harmonica reed being tested exceeds the upper limit of the specified thickness tolerance.

[0044] If the thickness of the tested harmonica reed is at the lower limit of the specified thickness tolerance, when the corresponding sealing airbag 13 is squeezed, the deformation of the sealing airbag 13 is small, and its pressure can push the piston plate 28 and the piston rod 29 fixed on the piston plate 28 to move in the piston cylinder 27. However, the moving distance is small, so the amount of water injected into the cavity 273 is small, and the water level change is small, which makes it easy to judge whether the thickness of the tested harmonica reed is less than the upper limit of the specified thickness tolerance.

[0045] If the thickness of the harmonica reed being tested is between the upper and lower limits of the specified thickness tolerance, the amount of water injected into the cavity 273 is higher than the water level of the harmonica reed when the thickness is at the lower limit of the specified thickness tolerance, but lower than the water level of the harmonica reed when the thickness is at the upper limit of the specified thickness tolerance.

[0046] After the test is completed, by observing the water level height of each scale display column 14, it is easy to determine whether the thickness of the tested harmonica reed is between the upper and lower limits of the specified thickness tolerance, and whether it is a qualified product.

[0047] When the test plate 31 moves up after the test is completed, the sealing airbag 13 returns to its original state, and the fourth spring 30 connected between the piston plate 28 and the piston cylinder 27 releases its elastic force, so that the piston plate 28 returns to its original state and the water in the scale display column 14 flows back into the piston cylinder 27.

[0048] Example 2 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1 to 7 This application also provides a magnifying component technical solution, the magnifying component includes a third abutting wedge 274, the third abutting wedge 274 is fixed on one end of the piston rod 29, a mounting bracket 275 is fixed on the anvil 32, a rocker plate 276 is rotatably connected to the mounting bracket 275, the scale display column 14 is slidably connected to the anvil 32 through a fifth spring 277, and the lower end of the scale display column 14 abuts against one end of the rocker plate 276, and the third abutting wedge 274 abuts against the other end of the rocker plate 276.

[0049] refer to Figure 5 If the thickness of the harmonica reed tested exceeds the upper limit of the specified thickness tolerance, and the deformation of the sealing airbag 13 is large, the gas inside the sealing airbag 13 will be compressed and transported to the piston cylinder 27 through the pipeline. Its pressure will push the piston plate 28 inside the piston cylinder 27 and the piston rod 29 fixed on the piston plate 28 to move horizontally synchronously. Furthermore, the third abutting wedge 274 on the piston rod 29 will move a large distance, causing the third abutting wedge 274 to move in tandem with one end of the rocker arm 276 rotatably connected to the mounting bracket 275. The contact causes the rocker 276 to deflect, pushing the scale display column 14 to move vertically on the anvil 32. The fifth spring 277 stores energy. When the scale display column 14 moves vertically on the anvil 32, the scale lines on the scale display column 14 also change. The deformation of the sealing airbag 13 is large, which increases the contact force of the third contact wedge 274 on the piston rod 29. Consequently, the deflection amplitude of the rocker 276 is large, resulting in a higher vertical movement distance of the scale display column 14 on the anvil 32.

[0050] Similarly, if the thickness of the tested harmonica reed is lower than the lower limit of the specified thickness tolerance, the deformation of the sealing airbag 13 is smaller, resulting in a smaller resistance force of the third abutment wedge 274 on the piston rod 29, causing a smaller deflection amplitude of the rocker 276, and a lower vertical movement height of the scale display column 14 on the anvil 32. By observing the vertical movement height of the scale display column 14, the horizontal movement distance of the piston plate 28 can be magnified, making it convenient to observe the position height of each scale display column 14 to determine whether the thickness of the tested harmonica reed is between the upper and lower limits of the specified thickness tolerance and whether it is a qualified product.

[0052] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
