Description

Technical Field

[0001] The utility model belongs to the technical field of ultrasonic water meter shell production, in particular to a clamping mechanism for ultrasonic water meter shell production. Background Art

[0002] In the related art, a compact ultrasonic water meter housing production clamp with publication number CN220660766U is disclosed. When in use, the device can play a buffering role during the clamping process, avoiding the phenomenon of the clamp applying excessive force when clamping and damaging the water meter housing. However, the device is not convenient for clamping a cylindrical ultrasonic water meter housing.

[0003] Since the ultrasonic water meter shell is mostly cylindrical or rectangular, and the surface of the cylindrical water meter shell is curved rather than flat, the clamping mechanism needs to be designed more precisely to ensure that the clamping force is evenly distributed on the shell surface, otherwise it will lead to loose clamping or deformation. However, when the device clamps the cylindrical ultrasonic water meter shell, there is a risk of rotation or sliding, causing the workpiece to move or rotate, affecting the processing accuracy and stability. Utility Model Content

[0004] The purpose of the utility model is to provide a clamping mechanism for the production of ultrasonic water meter shells. By setting up front and rear clamping mechanisms, the problem that the surface of the cylindrical water meter shell is a curved surface rather than a flat surface is solved. Therefore, the clamping mechanism needs to be designed more accurately to ensure that the clamping force is evenly distributed on the shell surface, otherwise it will lead to loose clamping or deformation. However, when the device clamps the cylindrical ultrasonic water meter shell, there is a risk of rotation or sliding, causing the workpiece to move or rotate, affecting the processing accuracy and stability.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting the front and rear clamping mechanism, when the left and right sides of the ultrasonic water meter housing need to be clamped, the bidirectional threaded rod on the fixed plate can be twisted, and the bidirectional threaded rod drives the two clamping plates through the two connecting blocks 1 to slide on the slide bar 1 in the direction of approaching each other through the connecting block 2, thereby clamping the front and rear of the ultrasonic water meter housing, so that the water meter housing can be firmly fixed on the machine tool during the processing to prevent it from moving or rotating, and the accuracy and stability of the processing can be guaranteed, thereby ensuring the product quality. When the front and rear parts of the water meter housing are clamped, the rest of the parts can be exposed for processing, and the operator can process the housing more easily without worrying about the position change or instability of the housing, thereby achieving more accurate processing;

[0017] 2. By setting up the left and right clamping mechanisms, when it is necessary to process the ultrasonic water meter shell, the ultrasonic water meter shell can be held by hand first to be located in the middle of the device, and then the hydraulic cylinder on the fixed block 1 is started. The hydraulic cylinder drives the two clamping plates 1 to approach each other through the connecting block 3 under the action of the gear and the rack, thereby clamping the left and right sides of the ultrasonic water meter shell, so that the processing interruption or reprocessing caused by the movement or instability of the shell can be reduced, thereby improving production efficiency and work efficiency. When the water meter shell needs to be adjusted or re-clamped, the left and right parts of the clamping mechanism can provide a stable support point, which is convenient for the operator to adjust, saves adjustment time, and ensures the accuracy of the adjusted position.

[0044] A specific application of this embodiment is: when in use, first hold the ultrasonic water meter housing so that it is located in the middle of the device, then start the hydraulic cylinder 32 on the fixed block 1 31, the hydraulic cylinder 32 drives the clamping plate 1 21 on the left to move to the right through the connecting block 3 34, the clamping plate 1 21 pushes the rack 39 at the rear to move to the right through the fixed block 2 37, the rack 39 at the rear drives the rack 39 at the front to move to the left through the gear 36, thereby driving the clamping plate 1 21 at the right to move to the left, clamping the left and right sides of the ultrasonic water meter housing, which can reduce the damage caused by the movement or instability of the housing. In the event of processing interruption or reprocessing, the production efficiency and work efficiency can be improved. When the left and right clamps of the ultrasonic water meter housing are stably clamped, the bidirectional threaded rod 24 on the fixed plate 23 can be twisted, and the bidirectional threaded rod 24 drives the two clamping plates 28 through the two connecting blocks 1 25 to slide on the slide bar 1 26 toward each other through the connecting block 27, thereby clamping the front and back of the ultrasonic water meter housing, which can ensure that the water meter housing is firmly fixed on the machine tool during the processing to prevent it from moving or rotating, and can ensure the accuracy and stability of the processing process, thereby ensuring product quality.
