Adjusting limiting mechanism for ultrasonic welding

Abstract

The invention discloses an adjusting limiting mechanism for ultrasonic welding. The adjusting limiting mechanism comprises a clamp, inclined blocks, screw rods, hoops, optical shafts, handles, pin shafts, a machine frame and nuts. According to the adjusting limiting mechanism for the ultrasonic welding, stable and reliable limiting precision can be obtained for high-frequency high-load equipment needing to be adjusted in place, when the clamp reaches a position, the inclined surface of the clamp collides with the inclined surfaces of the inclined blocks, the movement of the clamp is stopped, and the impact force is broken down into into component force in a vertical direction and a horizontal direction by the inclined surfaces of the inclined blocks, the screw rods are directly contacted with the machine frame in the vertical direction, so that the impact force is directly borne by the machine frame; the impact force in the horizontal direction is transmitted to the optical shafts, theoptical shafts are tightly held by the hoops and are fixed on the machine frame, so that the impact force in the horizontal direction is also absorbed by the rack finally; in the whole process, the clamp, the inclined blocks and the optical shafts are in surface contact, so that area of thrust surface is large, deformation is not easy, so that the requirement that the limiting precision is not influenced while the adjusting limiting mechanism is long-term uses is met; and the inclined blocks and the screw rods are connected through fine threads, so that the adjusting precision is ensured.

Description

technical field [0001] The invention relates to the technical field of limit mechanisms, in particular to an adjustment limit mechanism for ultrasonic welding. Background technique [0002] In actual production, sometimes the accuracy of the equipment cannot be guaranteed through machining or the equipment needs to be compatible with a variety of products, and the equipment needs to be adjusted. Due to cost and safety considerations, some equipment can only be adjusted manually. At present, most of the equipment adjustment is through screw adjustment. , which is convenient and can obtain high precision. However, due to the high load and frequency of some equipment, the screw teeth will be deformed due to impact force after long-term use, resulting in lower limit accuracy and even scrapped parts. In addition, there is also a buffer mechanism before the screw limit to reduce the impact force on the screw, but the buffer mechanism will inevitably reduce the movement speed of th...

[0002] In actual production, sometimes the accuracy of the equipment cannot be guaranteed through machining or the equipment needs to be compatible with a variety of products, and the equipment needs to be adjusted. Due to cost and safety considerations, some equipment can only be adjusted manually. At present, most of the equipment adjustment is through screw adjustment. , which is convenient and can obtain high precision. However, due to the high load and frequency of some equipment, the screw teeth will be deformed due to impact force after long-term use, resulting in lower limit accuracy and even scrapped parts.

In addition, there is also a buffer mechanism before the screw limit to reduce the impact force on the screw, but the buffer mechanism will inevitably reduce the movement speed of the equipment, resulting in a slowdown of the equipment beat, so it is not suitable for high-frequency equipment
