Description

Technical Field

[0001] This utility model belongs to the field of transducer processing technology, and in particular relates to a ceramic sheet clamping device for transducer processing. Background Technology

[0002] Ultrasonic water meters are widely used as water flow measurement instruments. The important part of an ultrasonic water meter is the measuring pipe section, i.e., the meter body. It is usually made of metal tubular parts that are machined and contain ultrasonic transducers, seals, and fasteners. Some are made of plastic non-metallic materials with reflective sheets and other parts. The transducer consists of a shell, matching layer, piezoelectric ceramic disc, backing, lead cable, and array receiver. During the assembly of the transducer, the piezoelectric ceramic disc needs to be bonded to the transducer shell. The bonding process requires first fixing the shell, then injecting special adhesive into the shell using a dispensing machine, and finally inserting the piezoelectric ceramic disc for bonding and fixing.

[0003] CN210531355U discloses a ceramic sheet clamping device for transducer processing. It includes a limiting fixture and a clamping module. The limiting fixture includes a limiting plate and a first counterweight plate, which are fixedly connected. The limiting plate has several limiting grooves and limiting posts at both ends. The clamping module includes a clamping plate and a second counterweight plate, which are fixedly connected. The clamping plate has several telescopic pressure rods, and both ends of the clamping plate and the second counterweight plate have limiting holes. The number of limiting grooves and telescopic pressure rods are the same and their positions correspond. Fixed-length pressure rods are provided at the center and four corners of the clamping plate, and positioning grooves are provided at the center and four corners of the limiting plate. This device ensures that the piezoelectric ceramic disc (ceramic sheet) remains horizontal, resulting in better transducer performance and extended transducer lifespan.

[0004] The following shortcomings were found during the use of the ceramic sheet clamping device;

[0005] 1. Because the size of the limiting groove is fixed, this device can only perform ceramic plate installation operations on transducer housings of a specific size.

[0006] 2. During use, the ceramic sheet must be completely fixed to the inner cavity of the transducer housing 3 with special adhesive before the transducer housing 3 can be removed. Then, the transducer housing 3 must be reinstalled one by one and the ceramic sheet is applied with adhesive one by one. This results in low efficiency of ceramic sheet installation.

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A ceramic sheet clamping device for transducer processing includes: an operating table and a clamping plate, wherein the clamping plate slides up and down in the middle of the top of the operating table; a mounting table, wherein there are two mounting tables, which are fixedly connected by a connecting rod, wherein the mounting tables slide left and right on the top of the operating table, and two sets of transducer housing clamping assemblies are provided on the top of the mounting tables, wherein the two sets of transducer housing clamping assemblies are symmetrically distributed on the top of the mounting tables, and each set of transducer housing clamping assemblies contains N components; the bottom of the clamping plate is provided with two sets of movable clamping assemblies that cooperate with the transducer housing clamping assemblies.

[0009] Furthermore, the movable clamping assembly includes a lifting rod disposed at the bottom of the clamping plate, N clamping rods welded to the bottom of the lifting rod, a detachable clamping head threadedly connected to the bottom of the clamping rod, and fixing rods welded to both the front and rear ends of the top of the lifting rod. The top of the fixing rod passes through the inner cavity of the clamping plate and extends to the outer side of the clamping plate. Two nuts are threadedly connected to the surface of the fixing rod, and the two nuts are respectively attached to the upper and lower sides of the clamping plate. An adjustment groove for the fixing rod to move is provided through the top of the clamping plate.

[0010] Furthermore, the number of N is ten.

[0011] Furthermore, the transducer housing clamping assembly includes two clamping plates that slide left and right on the top of the mounting platform. A sliding block is fixedly connected to the bottom of the clamping plates. A sliding groove for the sliding block to slide is provided on the top of the mounting platform. A guide rod is fixedly installed in the inner cavity of the mounting platform. The bottom of the sliding block extends into the inner cavity of the mounting platform and slides on the top of the guide rod. A movable block slides back and forth in the inner cavity of the mounting platform. Rotating rods are rotatably connected to the left and right sides of the top of the movable block. The end of the rotating rod away from the movable block is rotatably connected to the top of the sliding block.

[0012] Furthermore, the inner cavity of the mounting platform is rotatably connected to two threaded rods, and the movable blocks in the two sets of transducer housing clamping assemblies are respectively threaded to the surfaces of the two threaded rods.

[0013] Furthermore, a threaded rod is rotatably connected to the center of the top of the operating table. Guide rails are provided on both the front and rear sides of the threaded rod. The guide rails are fixedly installed on the top of the operating table. The bottom of the mounting platform is threadedly connected to the surface of the threaded rod, and the bottom of the mounting platform slides on the surface of the guide rails.

A cylinder is fixedly installed on the top of the top plate. The output end of the cylinder extends to the bottom of the top plate and is fixedly installed with the top of the clamping plate.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model achieves the installation and clamping of ceramic sheets on transducer housings of different sizes by using the transducer housing clamping assembly and the movable pressing assembly in combination. At the same time, with the setting of two mounting platforms, the pressing operation and loading and unloading can be carried out simultaneously, improving the efficiency of ceramic sheet clamping.

[0017] 2. By setting the adjustment groove, when the size of the transducer housing changes, the clamping heads in the two sets of movable clamping components also need to be adjusted so that the clamping heads can be lowered to clamp the ceramic plates in the transducer housing.

By setting the threaded rod two, this utility model can drive multiple movable blocks in the same group to slide synchronously in the inner cavity of the mounting platform, thereby linking the transducer housing clamping components in the same group to clamp multiple transducer housings synchronously, thus improving processing efficiency.

[0028] In the following description, embodiments of the ceramic sheet clamping device for transducer processing of the present invention will be described with reference to the accompanying drawings.

[0029] Figure 1-6 This invention illustrates a ceramic sheet pressing device for transducer processing according to an embodiment of the present invention. The device includes an operating table 1 and a pressing plate 2. The pressing plate 2 slides up and down in the middle of the top of the operating table 1. Specifically, two support columns 9 are welded to the front and rear ends of the middle of the top of the operating table 1. The pressing plate 2 slides up and down on the surface of the support columns 9. A top plate 10 is fixedly installed on the top of the support columns 9. A cylinder 11 is fixedly installed on the top of the top plate 10. The output end of the cylinder 11 extends to the bottom of the top plate 10 and is fixedly installed with the top of the pressing plate 2.

[0030] The system includes two mounting platforms 4, which are fixedly connected by a connecting rod 6. The mounting platforms 4 slide left and right on the top of the operating platform 1. Specifically, a threaded rod 7 is rotatably connected to the center of the top of the operating platform 1. Guide rails 8 are provided on both the front and rear sides of the threaded rod 7, and the guide rails 8 are fixedly installed on the top of the operating platform 1. The bottom of the mounting platform 4 is threadedly connected to the surface of the threaded rod 7, and the bottom of the mounting platform 4 slides on the surface of the guide rails 8. Two sets of transducer housing clamping assemblies 5 are provided on the top of the mounting platform 4, symmetrically distributed left and right on the top of the mounting platform 4. Each set of transducer housing clamping assemblies 5 contains N units. Specifically, each transducer housing clamping assembly 5 includes two clamping plates 51 that slide left and right on the top of the mounting platform 4. A sliding block 52 is fixedly connected to the bottom of the clamping plate 51. A sliding groove 13 is provided on the top of the mounting platform 4 for the sliding block 52 to slide. A guide rail is fixedly installed inside the cavity of the mounting platform 4. The bottom of the guide rod 53 and the sliding block 52 extend into the inner cavity of the mounting platform 4 and slide on the top of the guide rod 53. The inner cavity of the mounting platform 4 has a movable block 54 that slides back and forth. The left and right sides of the top of the movable block 54 are rotatably connected to the rotating rod 55. The end of the rotating rod 55 away from the movable block 54 is rotatably connected to the top of the sliding block 52. Specifically, the inner cavity of the mounting platform 4 is rotatably connected to two threaded rods 56. The movable blocks 54 in the two sets of transducer housing clamping assemblies 5 are respectively threaded to the surfaces of the two threaded rods 56. Through the setting of the threaded rods 56, multiple movable blocks 54 in the same group can be driven to slide synchronously in the inner cavity of the mounting platform 4, thereby linking the transducer housing clamping assemblies 5 in the same group to clamp multiple transducer housings synchronously, improving processing efficiency. The two threaded rods 56 are connected by a belt pulley. The inner cavity of the mounting platform 4 is equipped with a motor, and the output shaft of the motor is fixedly installed with one of the threaded rods 56.

[0031] The bottom of the clamping plate 2 is provided with a movable clamping assembly 3 that works in conjunction with the transducer housing clamping assembly 5. There are two sets of movable clamping assemblies 3. Specifically, each movable clamping assembly 3 includes a lifting rod 31 located at the bottom of the clamping plate 2. N clamping rods 32 are welded to the bottom of the lifting rod 31. A detachable clamping head 33 is threaded to the bottom of each clamping rod 32. Fixing rods 34 are welded to both the front and rear ends of the top of the lifting rod 31. The top of each fixing rod 34 passes through the inner cavity of the clamping plate 2 and extends to the outer side of the clamping plate 2. Two nuts 35 are threaded to the surface of each fixing rod 34. Nuts 35 are respectively attached to the upper and lower sides of the clamping plate 2. The top of the clamping plate 2 is provided with an adjustment groove 12 for the fixed rod 34 to move. With the setting of the adjustment groove 12, when the size of the transducer housing changes, the clamping heads 33 in the two sets of movable clamping assemblies 3 also need to be adjusted so that the clamping heads 33 can be moved down to clamp the ceramic sheet in the transducer housing. At this time, the fixed rod 34 only needs to slide in the inner cavity of the adjustment groove 12 to quickly adjust the position of the clamping head 33, thereby realizing the processing of transducer housings of different sizes. Specifically, the number of N is ten.

[0032] Working Principle: In use, the user places the transducer housings one by one between the two clamping plates 51 in each group of transducer housing clamping assemblies 5. Then, the motor inside the mounting platform 4 rotates, causing the two threaded rods 56 to rotate synchronously inside the mounting platform 4. This causes the movable blocks 54 in each group to slide synchronously backward inside the mounting platform 4, which in turn causes the rotating rod 55 to rotate and pull the two sliding blocks 52 to slide towards each other on the top plate of the guide rod 53. This allows the two clamping plates 51 to slide towards each other on the top plate of the mounting platform 4, clamping the transducer housings. Then, glue is injected into the inner cavity and ceramic plates are placed one by one. Finally... The cylinder 11 drives the clamping plate 2 to slide downward on the surface of the support column 9, thereby moving the clamping head 33 in the movable clamping assembly 3 down to the inner cavity of the transducer housing to clamp the ceramic sheet. At this time, the user can unload and reload the transducer housing on the top of the other mounting platform 4, so that the clamping operation and loading and unloading operations can be carried out simultaneously, improving the efficiency of ceramic sheet clamping. After the ceramic sheet is clamped and fixed, the threaded rod 7 is rotated to drive the two mounting platforms 4 to slide synchronously on the top of the guide rail 8, so that the mounting platform 4 to be clamped moves to the bottom of the clamping plate 2 for clamping operation, and the clamped transducer housing is unloaded.

[0033] In summary, this ceramic sheet clamping device for transducer processing, through the combined use of the transducer housing clamping assembly 5 and the movable clamping assembly 3, enables the installation and clamping of ceramic sheets on transducer housings of different sizes. Furthermore, the inclusion of two mounting platforms 4 allows for simultaneous clamping operations and loading / unloading, thereby improving the efficiency of ceramic sheet clamping.
